               The Exchange Offer will expire at 5:00 P.M.,
         New York City time, on            , 1998, unless extended
                          -----------------------

     RCN Corporation ("RCN") 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 9.80% Senior Discount Notes due 2008, Series B (the "New
Notes") of RCN for each $1,000 principal amount of the issued and outstanding
9.80% Senior Discount Notes due 2008, Series A (the "Old Notes," and together
with the New Notes, the "Notes") of RCN. As of the date of this Prospectus there
were outstanding $567,000,000 principal amount of Old Notes. The terms of the
New Notes are identical in all material respects to the Old Notes except that
the offer of the New Notes will have been registered under the Securities Act
and, therefore, the New Notes will not be subject to certain transfer
restrictions, registration rights and related liquidated damage provisions
applicable to the Old Notes.

     The Old Notes were issued at a substantial discount from their principal
amount at maturity and the purchase discount on the Old Notes accretes from
February 6, 1998 until February 15, 2003 Cash interest will be payable
semi-annually on February 15 and August 15 of each year, commencing August 15,
2003. See "Description of the New Notes." No interest will have accrued on the
Old Notes on the date of exchange for the New Notes and therefore no interest
will be paid thereon.

     The New Notes are being offered hereunder in order to satisfy certain
obligations of RCN under the Registration Rights Agreement, dated February 6,
1998, among RCN and the other signatories thereto (the "Registration Rights
Agreement"). Based upon interpretations contained in letters issued to third
parties by the staff of the Securities and Exchange Commission (the
"Commission"), RCN 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 each holder thereof (other than a broker-dealer, as set forth
below, and any such holder which is an "affiliate" of RCN 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 and such holder has no arrangement or
understanding with any person to participate in the distribution of such New
Notes. Each holder wishing to accept the Exchange Offer must represent to RCN in
the Letter of Transmittal that such conditions have been met. 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
such New Notes. The Letter of Transmittal states that by so acknowledging and
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 New Notes received in exchange for
Old Notes where such Old Notes were

the symbol "RCNC."

     See "Risk Factors" beginning on page 15 for a discussion of certain risk
factors that should be considered by holders prior to tendering their Old Notes
in the Exchange Offer.

acquired by such broker-dealer as a result of market-making activities or other
trading activities. RCN has agreed that, for a period of 90 days after the
Expiration Date (as defined herein), it will make this Prospectus available to
any broker-dealer for use in connection with any such resale. See "Plan of
Distribution."

     RCN will not receive any proceeds from the Exchange Offer. RCN will pay all
the expenses incident to the Exchange Offer. Tenders of Old Notes pursuant to
the Exchange Offer may be withdrawn at any time prior to the Expiration Date. In
the event RCN terminates the Exchange Offer and does not accept for exchange any
Old Notes, RCN will promptly return all previously tendered Old Notes to the
holders thereof. See "The Exchange Offer."

     Prior to this Exchange Offer, there has been no public market for the
Notes. RCN 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 than an active public market for the New Notes
will develop.

                                     SUMMARY

     The following is a brief summary of the matters covered by this Prospectus
and is qualified in its entirety by the more detailed information (including the
financial statements and the notes thereto) included elsewhere herein. All
amounts regarding shares and per share data of RCN Common Stock have been
adjusted to reflect the one for one stock dividend ("Stock Dividend") declared
on March 9, 1998 to be effective on April 3, 1998. Unless the context indicates
otherwise, "RCN" or "the Company" means RCN Corporation and its subsidiaries and
those joint ventures in which the Company exercises control.


                                   The Company

     RCN is developing advanced fiber optic networks to provide a wide range of
telecommunications services including local and long distance telephone, video
programming and data services (including high speed Internet access), primarily
to residential customers in selected markets in the Boston to Washington, D.C.
corridor. The region, one of the most densely populated in the United States,
represents approximately 4% of the geography of the U.S., but accounts for over
26% of the telecommunications market based upon the number of telephone access
lines. The Company believes that of the estimated 22 million homes in the Boston
to Washington, D.C. corridor, approximately 9 million homes are located in
high-density urban and suburban residential areas that will support development
of an advanced fiber optic network on an attractive economic basis. RCN believes
that its capability to deliver multiple services (telephone, video programming
and Internet access) to any given customer on its networks will provide it with
competitive advantages over other competitors. RCN's strategy is to become the
leading single-source provider of voice, video and data services to residential
customers in each of its markets by offering individual or bundled service
options, superior customer service and competitive prices.

     RCN's initial advanced fiber optic networks have been established in New
York City and, through a joint venture with the Boston Edison Company ("BECO"),
in Boston and surrounding communities. RCN has also entered into a joint venture
named Starpower Communications, LLC ("Starpower") with Pepco Communications,
L.L.C. ("Pepco Communications"), an indirect wholly owned subsidiary of Potomac
Electric Power Company ("PEPCO"), to develop an advanced fiber network in the
Washington, D.C. area. On February 20, 1998, RCN acquired Washington, D.C.'s
largest Internet service provider ("ISP"), Erols Internet, Inc. ("Erols"), and
on February 27, 1998, RCN acquired Boston's largest ISP, Ultranet
Communications, Inc. ("Ultranet"). RCN also benefits from a strategic
relationship with MFS Communications Company, Inc. (now a subsidiary of
WorldCom, Inc.) ("MFS/WorldCom") in New York City and Boston and from its
interconnection and resale agreements with incumbent telephone service providers
including Bell Atlantic. RCN believes that these joint ventures and
relationships provide it with a number of important advantages including access
to rights of way and use of existing fiber optic facilities, the ability to
enter its target markets quickly and efficiently and a reduction in the up-front
capital investment required to develop its networks. In addition, the Company's
joint venture partners provide access to additional assets, equity capital and
established customer bases. The Company also benefits from its relationship with
its largest shareholder, Peter Kiewit Sons' Inc. ("PKS"), the founder of MFS
Communications Company, Inc., and from the experience gained by certain of the
Company's key employees who participated in the development of MFS
Communications Company, Inc.

     As of December 31, 1997, the Company had approximately 267,600 connections
which were delivered through a variety of owned and leased facilities including
hybrid fiber/coaxial cable systems, a wireless video system and advanced fiber
optic networks. In addition, the Company gained approximately 325,000 Internet
service customers upon completion of the acquisitions of Ultranet and Erols.
Without giving effect to such acquisitions, RCN had pro forma revenues and
EBITDA (as defined below) before nonrecurring charges of $127.3 million and
$(7.7) million, respectively, for the year ended December 31, 1997 and $110.1
million and $23.5 million, respectively, for the year ended December 31, 1996.
The Company is deploying advanced fiber optic networks specifically designed to
provide high speed, high capacity telecommunications services for all new
network facilities. RCN also intends to upgrade certain of its hybrid
fiber/coaxial cable systems to enable them to provide the same range of voice,
video and data services, including bundled service options. See "Business--The
Delivery Platforms." Since it formally commenced operation of its advanced fiber
optic networks in New York City and Boston in September 1996, RCN has built or
acquired, through its joint venture with BECO and long term lease arrangements,
approximately 400 route miles of fiber optic cable and added approximately
15,100 customer connections to its advanced fiber optic networks. In addition,
during the same period the Company added approximately 29,700 wireless video,
resold telephone and other connections, the majority of which represent
customers that RCN expects to migrate to its advanced fiber optic networks. At
December 31, 1997, RCN had approximately 82,700 total connections attributable
to customers in the New York City and Boston markets (of which approximately
42,600 were wireless video service and other connections and approximately
24,900 were resold telephone connections) and had approximately 184,900
connections attributable to its hybrid fiber/coaxial cable systems in the states
of New York (outside New York City), New Jersey and Pennsylvania, all within 75
miles of New York City. Because it delivers multiple services, RCN reports the
total number of its various service connections (for local telephone, video
programming and Internet access) rather than the number of customers. See
"Business--RCN Services--Connections."

     RCN's extensive operating experience in both the telephone and video
industries and in the design and development of telecommunications facilities
provides it with expertise in systems operation and development, an established
infrastructure for customer service and billing for both voice and video
services and established relationships with providers of equipment and video
programming. In addition, the Company's management team and board of directors
benefit from experience gained in connection with the management of Commonwealth
Telephone Enterprises Inc. ("Commonwealth Telephone") (formerly C-TEC
Corporation ("C-TEC")), which prior to September 30, 1997 owned and operated
RCN. See "Description of the Distribution and Related Agreements--Background."
C-TEC has 100 years of experience in the telephone business and nearly 25 years
of experience in the cable television business. Both C-TEC and certain members
of management also have extensive experience in the design and development of
advanced telecommunications facilities.

     RCN seeks to exploit competitive opportunities which have resulted from
widespread changes in the U.S. telecommunications industry. Industry sources
estimate that annual revenues generated by the U.S. telecommunications industry
in 1996 were approximately $210 billion (comprised of $183 billion in
telecommunications revenues and $27 billion in cable television revenues).
Approximately 50% of such revenue is estimated to be attributable to residential
users. RCN believes that density is a critical factor in the effective economic
deployment of its networks, and that the Boston to Washington, D.C. corridor is
a particularly attractive market for developing advanced fiber optic facilities
due to population density, favorable demographics and the aging infrastructure
of the incumbent service providers' network facilities in this region. The
Company applies a subscriber-driven investment strategy focusing on subscriber
density, proximity to the Company's advanced fiber optic networks and network
development costs, in order to determine if the number of potential connections
in a target area will permit network development on an attractive economic
basis.

Business Strategy

     The Company believes that the opportunity to effectively deploy advanced
fiber optic networks and to compete with incumbent telephone and cable
television service providers results from several key factors, including the
broad deregulation of the telecommunications industry pursuant to the
Telecommunications Act of 1996, the need for more advanced, higher capacity
networks to meet growing consumer demands for new communications products and
services and the superior technology of the Company's networks. In order to
achieve its goal of becoming the leading provider of telecommunications, video
and data services to residential customers in its target markets, RCN is
pursuing the following key strategies:

     Developing Advanced Fiber Optic Networks. RCN's advanced fiber optic
networks are specifically designed to provide a single source for high speed,
high capacity voice, video programming and data services. RCN believes that its
high capacity advanced fiber optic networks provide RCN with certain competitive
advantages such as increased capacity (including the ability to offer bundled
voice, video and data services) and generally superior signal quality and
network reliability relative to the typical networks of the incumbent service
providers. By using advanced fiber optic networks capable of delivering multiple
services, RCN is able to address a larger number of potential subscriber
connections in its target markets than incumbent service providers which
typically provide only single or limited services.

     Focusing on Residential Customers in High-Density Markets. RCN seeks to be
the first operator of an advanced fiber optic network providing voice, video and
data services to residential customers in each of its target markets. RCN
believes that it is unique in its markets in offering a wide range of bundled
voice, video and data services to customers in residential areas and in striving
to connect residential customers directly to its advanced fiber optic networks.
RCN also believes that residential customers will be attracted to lower prices,
broader service offerings, enhanced levels of customer care and consumer choice.
Although the Company's primary focus is on residential customers, RCN also
serves certain commercial accounts which are located on or in close proximity to
its networks.

     Implementing Subscriber-Driven Investment Strategy. RCN attempts to
efficiently deploy its capital by tying facility development to the procurement
of customer connections. In order to promote its presence in its markets and to
develop a subscriber base for its advanced fiber optic networks, the Company may
provide telephone services to customers located near its advanced fiber networks
by first reselling services, and then by establishing leased facilities (such as
unbundled local loops), in advance of constructing or extending its networks.
RCN also provides wireless video services to approximately 38,000 customers in
New York City with a view to extending the advanced fiber optic network to
service many of these existing customers. In addition, RCN intends to extend its
network to cover most of the areas currently served by Erols and Ultranet.

     Utilizing Strategic Alliances and Existing Facilities to Speed and Reduce
Cost of Entry. By utilizing strategic alliances, RCN is able to enter the market
quickly and efficiently and to reduce the up-front capital investment required
to develop its networks. Through alliances with companies such as BECO, Pepco
Communications and MFS/WorldCom, which provide or are expected to provide RCN
with extensive fiber optic networks or other assets, by utilizing certain
components of its own existing cable television infrastructure, and through the
strategic acquisitions of Ultranet and Erols, RCN has been able to expedite and
reduce the cost of market entry and business development and has created the
opportunity to leverage existing customer relationships.

     Offering Bundled Voice, Video and Data Services. RCN believes that, as a
full service voice, video and data programming provider, it will be able to
offer a single-source package of voice, video and data services, individually or
on a bundled basis, which is not yet generally available from any incumbent
telephone, cable or other service provider. In addition, services provided over
RCN's advanced fiber optic networks are generally priced at competitive rates as
compared to the incumbent service providers.

     Providing Superior Customer Service. RCN seeks to provide superior customer
service as compared to incumbent service providers, with service features such
as a 24-hour-a-day call center and quality control system, on-time service
guarantees and bundled service offerings, providing the consumer with added
choice and convenience.

Recent Developments

     On February 20, 1998, RCN acquired Erols and on February 27, 1998, RCN
acquired Ultranet. With these acquisitions, RCN became a leading ISP in the
Boston to Washington, D.C. corridor, serving approximately 325,000 Internet
customers. See "Business--The Acquisitions of Ultranet and Erols" and
"Business--RCN Services--Connections."

     Erols is a leading regional ISP with approximately 293,000 residential and
business subscribers as of December 31, 1997 in targeted markets, including New
York City, Philadelphia, Washington, D.C. and Boston. RCN expects to contribute
to Starpower the subscribers acquired in the acquisition of Erols located in the
Washington, D.C. area in which Starpower operates. The joint venture partners of
Starpower are currently negotiating the terms of such contribution. On February
20, 1998, approximately 61% of all of Erols' subscribers were located in the
relevant Washington, D.C. area. Erols currently operates 57 physical points of
presence ("POPs") throughout its geographic markets, and also currently utilizes
32 "Virtual POPs," which permit subscribers located adjacent to, but outside of
the local calling areas of, physical POPs to dial into the Erols network on a
local basis through arrangements with the relevant local exchange carrier
("LEC"). Erols offers a broad range of Internet-based services, including (i)
Global Trader(sm), Erols' turn-key e-commerce product for small businesses, (ii)
Internet security services, including security consulting and virtual private
networks, and (iii) Web hosting, design and development services. RCN acquired
Erols in exchange for consideration consisting of $29.2 million in cash and
1,730,648 shares of RCN Common Stock plus the assumption and repayment of
approximately $5.8 million of debt (including payment of accrued interest). See
"Business--The Acquisitions of Ultranet and Erols--Merger With Erols Internet,
Inc."

     Ultranet is a leading ISP in the Boston area with more than 32,000
residential and business customers in New England. RCN contributed to its joint
venture with BECO the subscribers acquired in the acquisition of Ultranet
located in the Boston area in which the BECO joint venture operates as well as
1.36% (or all of Erols' subscribers located in the relevant Boston area) of the
subscribers acquired in the acquisition of Erols. On February 27, 1998,
approximately 27% of all of Ultranet's subscribers were located in the relevant
Boston area. Ultranet provides Internet service to over 500 schools, and is
presently building a network which will provide access throughout New
Hampshire's universities and colleges. Ultranet has a wide network of 42 POPs.
Services Ultranet offers to subscribers include (i) virtual hosting, which gives
customers a corporate presence on the Internet, (ii) firewall security, which
provides high quality control in monitoring access to documents and visitors to
the customer's websites, and (iii) UltraFax, which allows customers to send
faxes from their desktops. Ultranet also offers its customers access to its
network via an 800 number which allows access from every major city in the
world. RCN acquired Ultranet in exchange for consideration consisting of
approximately $7.9 million cash and 890,384 shares of RCN Common Stock. Ultranet
had total revenues of approximately $6.7 million for the year ended June 30,
1997. See "Business--The Acquisitions of Ultranet and Erols--Merger With
Ultranet Communications, Inc."

Key Strategic Relationships

     RCN has agreements in place with MFS/WorldCom which provide the Company
with the right to use portions of MFS/WorldCom's fiber networks in Boston and
New York City and under which MFS/WorldCom has agreed to install segments of
RCN's network. The Company is also developing alliances with utility companies
in its target markets, including joint ventures with BECO in Boston and with
Pepco Communications, an indirect subsidiary of PEPCO, in the Washington, D.C.
metropolitan area. The BECO joint venture provides RCN with access to and use of
certain existing BECO facilities and assets, including 126 fiber miles of BECO's
existing fiber backbone, and the ability to use BECO's real estate, poles,
easements and other interests for the construction and operation of the network.
The venture is 51% owned by RCN and is managed by RCN and is accounted for on a
consolidated basis. RCN and BECO have committed to provide additional equity
capital contributions to the joint venture on a 51% and 49% basis, respectively.
Starpower, the joint venture with Pepco Communications, provides RCN with access
to and use of certain existing facilities in the Washington, D.C. market
pursuant to a Fiber Use Agreement and other agreements. Starpower is owned 50%
by RCN and 50% by Pepco Communications and is accounted for under the equity
method of accounting. The parties have committed to make equity capital
contributions to the joint venture on a 50% and 50% basis; the venture is
managed by a committee on which RCN and Pepco Communications will have equal
representation. Utilities have a number of attributes which make them
particularly attractive as partners for the Company, including (i) contiguous
and broad geographic coverage with extensive conduits and rights-of-way, (ii)
significant access to capital, (iii) a reputation for reliability and customer
service and (iv) existing customer relationships (BECO and PEPCO served
approximately 660,000 and 687,000 customers, respectively, as of December 31,
1997). Through these joint ventures, RCN's joint venture partners have provided
or will provide access to extensive fiber optic facilities, as well as
commitments to make significant equity capital contributions throughout the term
of the respective joint venture agreements. The Company anticipates that its
joint venture partners will each contribute approximately $150 million in
capital contributions to the joint ventures in the period from September 30,
1997 through 2000 in order to fund capital expenditures at the joint venture
company level. RCN expects to contribute to Starpower the subscribers acquired
in the acquisition of Erols located in the Washington, D.C. area in which
Starpower operates. The joint venture partners of Starpower are currently
negotiating the terms of such contribution. On February 20, 1998, approximately
61% of all of Erols' subscribers were located in the relevant Washington, D.C.
area. RCN anticipates that Pepco Communications will make a contribution equal
to the value of such subscribers. RCN contributed to its joint venture with BECO
the subscribers acquired in the acquisition of Ultranet located in the Boston
area in which the BECO joint venture operates as well as 1.36% (or all of Erols'
subscribers located in the relevant Boston area) of the subscribers acquired in
the acquisition of Erols. On February 27, 1998, approximately 27% of all of
Ultranet's subscribers were located in the relevant Boston area. BECO has made a
corresponding contribution to the joint venture in the form of a note in the
principal amount of 49/51 of the agreed value of the subscribers contributed by
RCN.

Network Development and Financing Plan

     In developing its advanced fiber optic networks, the Company undertakes a
subscriber-driven capital expenditure strategy whereby it (i) closely monitors
development of its subscriber base in order to tailor network development in
each target market, and (ii) seeks to establish a customer base in advance of or
concurrently with its network deployment. As part of this development plan, RCN
pre-markets its services by offering resale telephone (and, in New York City,
wireless video) services in areas targeted for expansion of advanced fiber optic
network facilities. Depending upon factors such as subscriber density, proximity
to the advanced fiber optic network and development costs and the degree of
success achieved in its initial markets, the Company will determine whether
extending its advanced fiber optic network to additional high density target
markets can be achieved on an attractive economic basis.

     The Company expects that it will require a substantial amount of capital to
fund the network development and operations in the Boston to Washington, D.C.
corridor, including funding the development of its advanced fiber optic
networks, upgrading its hybrid fiber/coaxial plant and funding operating losses
and debt service requirements. The Company currently estimates that its capital
requirements for the period from January 1, 1998 through 1999 will be
approximately $785 million, which includes capital expenditures (including
connection costs which will only be incurred as the Company obtains
revenue-generating customer connections) of approximately $300 million in 1998
and approximately $485 million through 1999. These capital expenditures will be
used principally to fund the buildout of the Company's fiber optic network in
high density areas in the Boston, New York and Washington, D.C. markets and to
upgrade its hybrid fiber/coaxial cable systems. In addition to its own capital
requirements, the Company's joint venture partners are each expected to
contribute approximately $150 million in capital to the joint ventures through
2000 in connection with development of the Boston and Washington, D.C. markets.
Immediately following the consummation of the acquisition of Erols (the
"Acquisition") and the placement of the Old Notes on February 6, 1998, (the
"Offering"), the Company had approximately $993 million of cash and cash
equivalents and approximately $62 million of restricted cash. Such amounts are
expected to provide sufficient liquidity to meet the Company's capital
requirements through mid-2000.

     The Company will continue to require additional capital for planned
increases in network coverage and other capital expenditures, working capital,
debt service requirements and anticipated further operating losses. Sources of
funding for the Company's further financing requirements may include vendor
financing, public offerings or private placements of equity and/or debt
securities, and bank loans. There can be no assurance that additional financing
will be available to the Company or, if available, that it can be obtained on a
timely basis and on acceptable terms. See "Risk Factors--Further Capital
Requirements" and "Management's Discussion and Analysis of Financial Condition
and Results of Operations--Liquidity and Capital Resources."

The Distribution

     Prior to September 30, 1997, the Company was operated as a wholly-owned
subsidiary of C-TEC. On February 12, 1997, the C-TEC Board of Directors approved
a plan to restructure C-TEC, and, among other things, create a separate company
consisting of the businesses and operations that now comprise RCN (the "RCN
Businesses") and the associated assets and liabilities of such businesses and
operations, and to distribute to its stockholders all of its interest in the RCN
Businesses (the "Distribution") and all of its interests in Cable Michigan, Inc.
("Cable Michigan"), a Pennsylvania corporation that operates cable television
systems in the State of Michigan (the "Cable Michigan Distribution"). On
September 30, 1997 (the "Distribution Date"), each holder of record of C-TEC's
common stock, par value $1.00 per share ("C-TEC Common Stock"), and holders of
C-TEC's Class B Common Stock, par value $1.00 per share ("C-TEC Class B Common
Stock" and together with the C-TEC Common Stock, the "C-TEC Common Equity")
received (i) two shares (when adjusted for the Stock Dividend) of RCN Common
Stock for every one share of C-TEC Common Equity held as of September 19, 1997
(the "Record Date") and one share of Cable Michigan Common Stock for every four
shares of C-TEC Common Equity held as of the Record Date. Following the
Distribution and the Cable Michigan Distribution, C-TEC changed its name to
Commonwealth Telephone Enterprises Inc. The Company, Commonwealth Telephone and
Cable Michigan have entered into certain agreements providing for the
Distribution and the Cable Michigan Distribution, and governing various ongoing
relationships between the three companies, including a distribution agreement
and a tax sharing agreement. See "Description of the Distribution and Related
Agreements."

                                   2008, Series B. The terms of the New Notes
                                   and the Old Notes are identical in all
                                   material respects, except that the offer of
                                   the New Notes will have been registered under
                                   the Securities Act and, therefore, the New
                                   Notes will not be subject to certain transfer
                                   restrictions, registration rights and related
                                   liquidated damage provisions applicable to
                                   the Old Notes.

The Exchange Offer..............   RCN is offering, upon the terms and subject
                                   to the conditions of the Exchange Offer, to

                                   for each $1,000 principal amount of Old
                                   Notes. See "The Exchange Offer" for a
                                   description of the procedures for tendering
                                   Old Notes. The Exchange Offer is intended to
                                   satisfy obligations of the Company under the
                                   Registration Rights Agreement, dated February

                                   termination of the Exchange Offer.

Certain Federal Income 
Tax Considerations..............   The exchange of Old Notes for New Notes
                                   pursuant to the Exchange Offer will not
                                   result in any income, gain or loss to the
                                   holders or the Company for federal income tax
                                   purposes. See "Certain U.S. Federal Income
                                   Tax Considerations."

Use of Proceeds.................   There will be no proceeds to the Company from
                                   the issuance of the New Notes pursuant to the
                                   Exchange Offer.

Exchange Agent..................   The Chase Manhattan Bank is serving as
                                   Exchange Agent in connection with the
                                   Exchange Offer.


                      Consequences of Exchanging Old Notes
                         Pursuant to the Exchange Offer

     Based upon interpretations contained in letters issued to third parties by
the staff of the commission, the company believes that, generally, any holder of
Old Notes (other than a broker-dealer, as set forth below, and any holder who is
an "affiliate" of the Company within the meaning of Rule 405 under the
Securities Act) who exchanges its Old Notes for New Notes pursuant to the
Exchange Offer may offer such New Notes for resale, resell such New Notes, or
otherwise transfer such 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 and such holder has
no arrangement or understanding with any person to participate in a distribution
of such New Notes. Each holder wishing to accept the Exchange Offer must
represent to the Company in the Letter of Transmittal that such conditions have
been met. 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 such 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 does not currently intend to take any action to register or
qualify the New Notes for resale in any such jurisdictions. If a holder of Old
Notes does not exchange such Old Notes for New Notes pursuant to the Exchange
Offer, 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, except pursuant to
an exemption from, or in a transaction not subject to, the Securities Act and
applicable state securities laws. Any holder who tenders in the Exchange Offer
with the intention to participate, or for the purpose of participating, in a
distribution of New Notes could not rely on the position of the staff of the
Commission enunciated in Exxon Capital Holdings Corporation (available May 13,
1988) or similar no-action letters and, in the absence of an exemption
therefrom, must comply with the registration and prospectus delivery
requirements of the Securities Act in connection with a secondary resale
transaction. Failure to comply with such requirements in such instance may
result in such holder incurring liability under the Securities Act for which the
holder is not indemnified by the Company. See "The Exchange Offer--Consequences
of Failure to Exchange."


                      SUMMARY DESCRIPTION OF THE NEW NOTES

Securities Offered.............    $567,000,000 aggregate principal amount at
                                   maturity of 9.80% of Senior Discount Notes
                                   due 2008, Series B. The New Notes will be
                                   issued at a discount to their aggregate
                                   principal amount at maturity. The yield to
                                   maturity of the Notes will be 9.80% (computed
                                   on a semi-annual bond equivalent basis),
                                   calculated from February 6, 1998. See
                                   "Certain U.S. Federal Income Tax
                                   Considerations."

Maturity Date..................    February 15, 2008.

Ranking........................    The Notes will be senior unsecured
                                   obligations of RCN. The Notes will rank
                                   senior in right of payment to all
                                   subordinated indebtedness of RCN and will
                                   rank pari passu in right of payment with all
                                   existing and future indebtedness of RCN that
                                   is not by its terms subordinated in right and
                                   priority to the Notes. In addition, claims of
                                   holders of the Notes will be structurally
                                   subordinated to claims of holders of
                                   indebtedness of RCN's subsidiaries. As of
                                   September 30, 1997, the aggregate amount of
                                   indebtedness outstanding under the Credit
                                   Agreement to which holders of Notes would
                                   have been structurally subordinated was
                                   approximately $110 million. In addition,
                                   subsequent to September 30, 1997, RCN issued
                                   $225 million aggregate principal amount
                                   outstanding of 10% Senior Notes due 2007 and
                                   approximately $601 million aggregate
                                   principal amount at maturity of 111/8% Senior
                                   Discount Notes due 2007 for gross proceeds of
                                   approximately $350 million (together, the
                                   "1997 Notes Offering"). RCN and its
                                   subsidiaries are expected to incur
                                   substantial additional indebtedness.

Interest.......................    Cash interest will not accrue on the Notes
                                   prior to February 15, 2003. Thereafter, cash
                                   interest on the Notes will accrue at a rate
                                   of 9.80% per annum and will be payable semi-
                                   annually in arrears on each February 15 and
                                   August 15 of each year, commencing August 15,
                                   2003.

Original Issue Discount........    For federal income tax purposes, the Notes
                                   will be treated as having been issued with
                                   "original issue discount" equal to the
                                   difference between the issue price of the
                                   Notes and the sum of all cash payments
                                   (whether denominated as principal or
                                   interest) to be made thereon. Each holder of
                                   a Note must include as gross income for
                                   federal income tax purposes a portion of such
                                   original issue discount for each day during
                                   each taxable year in which a Note is held
                                   even though no cash interest payments will be
                                   received prior to August 15, 2003. See
                                   "Certain U.S. Federal Income Tax
                                   Considerations."

Optional Redemption............    The Notes will be redeemable at the option of
                                   RCN, in whole or in part, at any time on or
                                   after February 15, 2003 at the redemption
                                   prices set forth under "Description of the
                                   New Notes--Redemption," plus accrued and
                                   unpaid interest, if any, thereon to the date
                                   of redemption. In addition, prior to February
                                   15, 2001, RCN may use the net proceeds of one
                                   or more Public Equity Offerings (as defined)
                                   of RCN yielding gross cash proceeds of at
                                   least $30 million to redeem up to an
                                   aggregate of 35% of the principal amount at
                                   maturity of the Notes originally issued (on a
                                   pro rata basis) at a redemption price equal
                                   to 109.80% of the Accreted Value at the
                                   redemption date of the Notes so redeemed.

Change of Control..............    In the event of a Change of Control, RCN will
                                   be required to make an offer to purchase all
                                   outstanding Notes at a purchase price equal
                                   to 101% of the Accreted Value thereof plus
                                   accrued and unpaid interest, if any, thereon
                                   to the date of purchase. See "Description of
                                   the New Notes--Certain Covenants--Change of
                                   Control" for a discussion of such covenant.

Asset Sale Offer...............    In addition, RCN will, subject to certain
                                   conditions, be obligated to make an offer to
                                   purchase Notes with the Net Cash Proceeds of
                                   certain Asset Sales at a price of 100% of the
                                   Accreted Value thereof plus accrued and
                                   unpaid interest, if any, to the date of
                                   purchase. See "Description of the New
                                   Notes--Certain Covenants--Disposition of
                                   Proceeds of Asset Sales."

Certain Covenants..............    The indenture under which the Notes will be
                                   issued (the "Indenture") will contain certain
                                   covenants, including (i) limitations on
                                   additional indebtedness, (ii) limitations on
                                   restricted payments, (iii) limitations on
                                   liens securing certain indebtedness, (iv)
                                   limitations on certain guarantees, (v)
                                   limitations on dividend and other payment
                                   restrictions affecting Restricted
                                   Subsidiaries or Restricted Affiliates (as
                                   defined), (vi) limitations on transactions
                                   with affiliates, (vii) limitations on
                                   issuances and sales of Preferred Stock by
                                   Restricted Subsidiaries and Restricted
                                   Affiliates (as defined), (viii) limitations
                                   on the disposition of proceeds of asset sales
                                   and (ix) limitations on designations of
                                   Unrestricted Subsidiaries (as defined) and
                                   Restricted Affiliates. In addition, the
                                   Indenture limits the ability of RCN to
                                   consolidate, merge or sell all or
                                   substantially all of its assets. These
                                   covenants are subject to important exceptions
                                   and qualifications. See "Description of the
                                   New Notes--Certain Covenants."

Absence of a Public 
Market for the Notes...........    The Notes are new securities for which there
                                   is currently no established trading market.
                                   Although the initial purchasers of the Old
                                   Notes have informed RCN that they currently
                                   intend to make a market in the Notes, they
                                   are not obligated to do so and any such
                                   market making may be discontinued at any time
                                   without notice. Accordingly, there can be no
                                   assurance as to the development or liquidity
                                   of any market for the Notes. RCN does not
                                   intend to apply for listing of the Notes on
                                   any securities exchange or for quotation
                                   through NASDAQ.

Use of Proceeds................    There will be no proceeds to the Company from
                                   the issuance of New Notes.


                                  Risk Factors

     Holders of Old Notes should carefully consider all of the information set
forth in this Prospectus and, in particular, should evaluate the specific risk
factors set forth under "Risk Factors," beginning on page 15, for a discussion
of certain risks involved with an investment in the New Notes before accepting
the Exchange Offer.

                 Summary Historical Consolidated Financial Data

     Prior to September 30, 1997, the Company operated as part of C-TEC. The
table below sets forth selected historical consolidated financial data for RCN.
The historical financial data presented below reflect periods during which the
Company did not operate as an independent company and, accordingly, certain
assumptions were made in preparing such financial data. Therefore, such data may
not reflect the results of operations or the financial condition which would
have resulted if the Company had operated as a separate, independent company
during such periods, and are not necessarily indicative of the Company's future
results of operation or financial condition.

     The selected historical consolidated financial data for the years ended
December 31, 1994 and 1993 and as of December 31, 1995, 1994 and 1993 are
derived from the Company's unaudited historical consolidated financial
statements not included in this Prospectus. The selected historical consolidated
financial data of the Company for the years ended December 31, 1997, 1996 and
1995 and as of December 31, 1997 and 1996 are derived from and should be read in
conjunction with the Company's audited historical consolidated financial
statements (the "Financial Statements") and the Company's unaudited pro forma
consolidated financial statements included elsewhere in this Prospectus. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations," "Unaudited Pro Forma Consolidated Financial Statements" and the
Financial Statements.

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

(1)  Certain of the Company's businesses were acquired by C-TEC and transferred
     to the Company in connection with the Distribution. In May 1995, a
     subsidiary of C-TEC acquired Twin County Trans Video, Inc. ("Twin County")
     and accordingly Twin County is fully consolidated in the Company's
     financial statements since the date of acquisition. See Note 4 to the
     Consolidated Financial Statements of the Company.

(2)  Nonrecurring charges of $10,000 represent costs incurred with respect to
     the termination of a marketing services agreement related to the Company's
     wireless video services.

(3)  Equity in loss of unconsolidated entities primarily consists of the
     Company's proportionate share of income (losses) and amortization of excess
     cost over net assets of Megacable, S.A. de C.V. ("Megacable"). The Company
     purchased its 40% equity interest in Megacable in January 1995 and accounts
     for its investment by the equity method of accounting.

(4)  In 1997, the minority interest in (income) loss of consolidated entities
     consists of minority losses of the RCN-BECOCOM joint venture of $6,562,
     minority losses of Freedom New York, L.L.C. ("Freedom") through March 1997
     of $966 and minority income earned by a cable television partnership of
     $(232). The minority interest in (income) loss of consolidated entities
     primarily consists of the approximately 20% minority interest in the loss
     of Freedom in 1996. Prior to 1996 the minority interest represents minority
     income earned by a cable television partnership.

(5)  The cumulative effect of changes in accounting principles reflects the
     adoption of Statement of Financial Accounting Standards No. 109 "Accounting
     for Income Taxes" in 1993 and the accounting for benefits under Statement
     of Financial Accounting Standards No. 112-- "Employers' Accounting for
     Postemployment Benefits" in 1994.

(6)  Extraordinary charge represents the fee, net of taxes, paid in connection
     with the early prepayment of Senior Secured Notes of C-TEC Cable Systems,
     Inc. The Senior Secured Notes were prepaid in connection with the Company's
     acquisition of a new $125,000 credit agreement comprised of a five year
     revolving credit facility in the amount of $25,000 and a $100,000 term
     credit facility which is to be repaid over six years in quarterly
     installments from September 30, 1997 through June 30, 2005.

(7)  During 1994, C-TEC transferred to the Company an equity contribution of
     $298,759 primarily representing net proceeds from a C-TEC common stock
     rights offering.



                        Summary Pro Forma Financial Data

     The following unaudited summary pro forma financial data include
adjustments to the historical statements of operations of the Company for the
years ended December 31, 1997 and 1996 as if the Distribution, borrowings of
$110 million under the Credit Agreement, the 1997 Notes Offering, the
Acquisition and the issuance of the Notes had occurred on the first day of the
respective periods. Such adjustments result primarily from changes in the
capital structure of the Company and accounting for the Acquisition. See
"Unaudited Pro Forma Consolidated Financial Statements" and the notes thereto.
The following unaudited pro forma financial data for the respective periods are
provided for information purposes only and should not be construed to be
indicative of the Company's results of operations or financial condition had the
Distribution, borrowings of $110 million under the Credit Agreement, the 1997
Notes Offering, the Acquisition and the issuance of the Notes had occurred on
the dates assumed, may not reflect the results of operations or financial
condition which would have resulted had the Company been operated as a separate,
independent Company during such period, and are not necessarily indicative of
the Company's future results of operations or financial condition.

                                  RISK FACTORS

     In addition to the other information contained in this Prospectus, holders
of Old Notes should carefully review the following factors before accepting the
Exchange Offer.

     This Prospectus contains certain forward-looking statements regarding the
Company's operations, economic performance and financial condition, including,
in particular, statements made as to plans to develop networks and upgrade
facilities, the market opportunity presented by markets targeted by the Company,
the Company's intention to connect certain wireless video and resale telephone
customers to its advanced fiber optic networks, the development of the Company's
businesses, the markets for the Company's services and products, the Company's
anticipated capital expenditures, the Company's anticipated sources of capital
and effects of regulatory reform and competitive and technological developments.
Such forward-looking statements are subject to known and unknown risks and
uncertainties. Actual results could differ materially from those currently
anticipated due to a number of factors, including those identified in this
Section and elsewhere in this Prospectus. Such risks include, but are not
limited to, the Company's ability to successfully market its services to current
and new customers, connect existing customers to its advanced fiber optic
networks, access markets, finance network development, design and construct
fiber optic networks, install or lease fiber optic cable and other facilities,
including switching electronics, and obtain rights-of-way, building access
rights and any required governmental authorizations, franchises and permits, all
in a timely manner, at reasonable costs and on satisfactory terms and
conditions, as well as regulatory, legislative, judicial, competitive and
technological developments that could cause actual results to vary materially
from the future results indicated, expressed or implied, in such forward-looking
statements.

Limited Operating History; Negative Cash Flow; Operating Losses

     The Company has only recently begun operating a voice, video and data
services business and this business has only a limited operating history upon
which investors may base an evaluation of its performance. In connection with
entering this business, the Company has incurred operating and net losses and
negative cash flows to build its networks and pursue its business plans and
expects to continue to do so for the foreseeable future as its expands its
network and customer base. The extent to which it continues to experience
negative cash flow in the future will be affected by a variety of factors,
including the pace of its entry into new markets, the time and expense required
for building out its planned network, its success in marketing its services, the
intensity of the competition experienced by the Company and the availability of
additional capital to pursue its business plans. The Company had operating
losses after depreciation and amortization and nonrecurring charges of
$70,875,000, $13,078,000 and $5,342,000 for the years ended December 31, 1997,
1996 and 1995. On a pro forma basis, the Company had operating losses after
depreciation and amortization and nonrecurring charges of $91,930,000 and
$45,457,000 for the years ended December 31, 1997 and 1996. There can be no
assurance that the Company will achieve or sustain profitability or positive
cash flows from operating activities in the future. See "Management's Discussion
and Analysis of Financial Condition and Results of Operations."

Further Capital Requirements

     The Company expects that it will require a substantial amount of capital to
fund the development and operations of business in the Boston to Washington,
D.C. corridor, including to fund its advanced fiber optic networks, the upgrade
of hybrid fiber/coaxial plant, the funding of operating losses and debt service
requirements. The Company currently estimates that its capital requirements for
the period from January 1, 1998 through 1999 will be approximately $785 million,
which includes capital expenditures (including connection costs which will only
be incurred as the Company obtains revenue generating customer connections) of
approximately $300 million in 1998 and approximately $485 million through 1999.
These capital expenditures will be used principally to fund the buildout of the
Company's fiber optic network in high density areas in the Boston, New York and
Washington, D.C. markets and represent only the Company's proportionate share of
the funding requirements of the Boston and Washington, D.C. joint ventures. The
Company is obligated to fund its portion of any capital contributions required
by the joint ventures' annual budget or capital contribution schedule. See
"--Dependence on Strategic Relationships; Terms of Joint Venture Arrangements."
The Company expects that its joint venture partners will each contribute
approximately $150 million in capital to the joint ventures in the period from
September 30, 1997 through 2000 in order to fund capital expenditures at the
joint venture company level. RCN expects to contribute to Starpower, the joint
venture with Pepco Communications, the subscribers acquired in the acquisition
of Erols located in the Washington, D.C. area in which Starpower operates. The
joint venture partners of Starpower are currently negotiating the terms of such
contribution. On February 20, 1998, approximately 61% of all of Erols'
subscribers were located in the relevant Washington, D.C. area. RCN anticipates
that Pepco Communications will make a contribution equal to the value of such
subscribers. Failure by its joint venture partner(s) to make anticipated capital
contributions could have a material adverse effect on the Company.

     The Company believes that, following the consummation of the Offering, it
has sufficient liquidity to meet its capital requirements through mid-2000. The
actual timing and amount of capital required for the rollout of the Company's
network and to fund operating losses may vary materially from the Company's
estimates and additional funds will be required in the event of significant
departures from the current business plan, unforeseen delays, cost overruns,
engineering design changes and other technological risks or to meet other
unanticipated expenses. The Company will continue to require additional capital
for planned increases in network coverage and other capital expenditures,
working capital, debt service requirements and anticipated further operating
losses. Sources of funding for the Company's further financing requirements may
include vendor financing, public offerings or private placements of equity
and/or debt securities, and bank loans. There can be no assurance that
additional financing will be available to the Company or, if available, that it
can be obtained on a timely basis and on acceptable terms. Failure to obtain
such financing could result in the delay or curtailment of the Company's
development and expansion plans and expenditures. Any of these events could
impair the Company's ability to meet its debt service requirements and could
have a material adverse effect on its business. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations."

Substantial Indebtedness; Effect of Financial Leverage

     The Company has indebtedness that is substantial in relation to its
shareholders' equity and cash flow. As of December 31, 1997, on a pro forma
basis, the Company had an aggregate of approximately $1,039 million of
indebtedness outstanding, representing 71.8% of total capitalization, and the
ability to borrow up to an additional $22 million under the Credit Agreement. As
a result of the substantial indebtedness of the Company following the Offering,
the Company's fixed charges are expected to exceed its earnings for the
foreseeable future and there can be no assurance that the Company's operating
cash flow will be sufficient to pay interest on the Notes following February 15,
2003. In addition, the Company will require, and the Indenture permits the
Company to incur, substantial additional indebtedness, particularly in
connection with the buildout of the Company's networks and the introduction of
its telecommunications services to new markets. The leveraged nature of the
Company could limit its ability to effect future financings or may otherwise
restrict the Company's business activities.

     The extent of the Company's leverage may have the following consequences:
(i) limit the ability of the Company to obtain necessary financing in the future
for working capital, capital expenditures, debt service requirements or other
purposes, (ii) require that a substantial portion of the Company's cash flows
from operations be dedicated to the payment of principal and interest on its
indebtedness and therefore not be available for other purposes; (iii) limit the
Company's flexibility in planning for, or reacting to, changes in its business;
(iv) place the Company at a competitive disadvantage as compared with less
leveraged competitors; and (v) render the Company more vulnerable in the event
of a downturn in its business.

Holding Company Structure; Structural Subordination

     RCN is a holding company with limited assets that conducts substantially
all of its operations through subsidiaries and joint ventures. The Notes will be
solely obligations of RCN and no other entity has any obligation, contingent or
otherwise, to make payments in respect of the Notes. Accordingly, RCN will be
dependent on dividends and other distributions from its subsidiaries and joint
ventures to generate the funds necessary to meet its obligations, including the
payment of principal and interest on the Notes. The ability of the Company's
subsidiaries and joint ventures to pay dividends to RCN will be subject to,
among other things, the terms of any debt instruments and applicable law. In
addition, the terms of the Company's joint ventures require the mutual consent
of the Company and its joint venture partner to distribute or advance funds to
the Company. Claims of holders of the Notes will be effectively subordinated to
the indebtedness and other liabilities and commitments of RCN's subsidiaries and
joint ventures and the interest of RCN in its joint ventures will be limited to
the extent of its direct or indirect equity interest in such entities.
Consequently, in the event of an insolvency, liquidation, reorganization,
dissolution or other winding up of the Company's subsidiaries and joint
ventures, the ability of RCN's creditors, including holders of the Notes, will
be subject to the prior claims of those entities' creditors, including trade
creditors, and any prior or equal claim of any joint venture partner. Any
distributions in respect of RCN's equity interests in non-wholly owned
subsidiaries or in joint ventures may be expected to be made on a pro rata basis
to all equity holders. The Company expects that a majority of its cash flow in
the advanced fiber optic network business will ultimately derive from its joint
venture investments. The Indenture permits substantial indebtedness to be
incurred by subsidiaries and joint ventures of RCN and does not, except under
limited circumstances, require a guarantee by subsidiaries of RCN. In addition,
the Indenture permits the Company's subsidiaries and joint ventures to become
parties to debt instruments that limit such entities' ability to pay dividends
or make distributions to RCN.

Ability to Manage Growth; Risks Related to Acquisitions

     The expansion and development of the Company's operations (including the
construction and development of additional networks) will depend on, among other
things, the Company's ability to assess markets, design fiber optic network
backbone routes, install or lease fiber optic cable and other facilities,
including switches, and obtain rights-of-way, building access rights and any
required government authorizations, franchises and permits, all in a timely
manner, at reasonable costs and on satisfactory terms and conditions. There can
be no assurance that the Company will be able to expand its existing network.
Furthermore, the Company's ability to manage its expansion effectively will also
require it to continue to implement and improve its operating and administrative
systems and attract and retain qualified management and professional and
technical personnel. If the Company were not able to manage its planned
expansion effectively it could have a material adverse effect on the Company.

     Although the Company's acquisitions of Erols and Ultranet were consummated
in February, 1998, the process of integrating the business of the ISPs into the
Company may take a significant period of time, may place a significant strain on
the Company's resources, and could subject the Company to additional expenses
during the integration process. In addition, RCN expects that it will need to
upgrade the systems and controls of the companies being acquired. As a result,
there can be no assurance that the Company will be able to successfully
integrate these ISPs successfully or in a timely manner. See "--Risks Relating
to Provision of Internet Services."

Rapid Technological Changes

     The telecommunication 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 its ability to acquire
necessary technologies, the effect of technological changes on the business of
the Company cannot be predicted. There can be no assurance that technological
developments in telecommunications will not have a material adverse effect on
the Company.

Dependence on Strategic Relationships; Terms of Joint Venture Arrangements

     The Company has entered into a number of strategic alliances and
relationships in order to provide it with early entry into the market for
telecommunications services. As the Company's network is further developed, it
will be dependent on these arrangements to provide the full range of its
telecommunication service offerings. The key strategic relationships include (1)
RCN's arrangements with MFS/WorldCom to, among other things, lease portions of
MFS/WorldCom's fiber optic network in New York City and Boston, (2) RCN's joint
venture with BECO under which the Company has access to BECO's extensive fiber
optic network in Greater Boston and (3) RCN's joint venture with Pepco
Communications, an indirect subsidiary of PEPCO, to develop an advanced fiber
optic network in the Washington, D.C. market. See "Business--Strategic
Relationships." The Company also has in place arrangements to act as a reseller
of Bell Atlantic local telephone services and arrangements to lease Bell
Atlantic unbundled local loop and T-1 facilities (including Bell Atlantic
services previously provided by NYNEX). Any disruption of these relationships or
arrangements could have a material adverse effect on the Company. The Company
has also executed comprehensive telephone service co-carrier interconnection
agreements with Bell Atlantic and Sprint, covering, along with the District of
Columbia, ten states in the Northeast and New England-Middle Atlantic corridor
areas, which the Company has targeted as its initial geographic markets. The
Company may be required to negotiate new interconnection agreements from time to
time and as it enters new markets in the future. There can be no assurance that
the Company will successfully negotiate such other agreements for
interconnection with the incumbent local exchange carrier or renewals of
existing interconnection agreements. The failure to negotiate or renew required
interconnection agreements could have a material adverse effect on the Company.

     The agreements governing the Company's joint ventures with BECO and Pepco
Communications contain material provisions for the management, governance and
ownership of the Greater Boston and Washington, D. C. businesses, respectively.
The Boston Joint Venture Agreement (as defined under "Business--Strategic
Relationships") provides, among other things, that (1) certain fundamental
business actions, such as material capital expenditures, debt incurrences and
distributions to the Company and BECO, require the joint approval of RCN and
BECO; (2) neither RCN nor BECO may transfer their interests in the joint venture
for a period of three years without the other's consent and, thereafter, may
only do so while observing certain rights of first offer and tag-along rights;
(3) upon a change of control (as defined) of RCN Telecom Services of
Massachusetts ("RCN Massachusetts") or BECOCOM, Inc. ("BECOCOM"), the other
party has the right to acquire all of the equity interest in the joint venture
for fair market value; (4) following certain deadlock events (defined generally
as an inability of RCN and BECO to agree upon certain fundamental business
actions requiring mutual consent), either RCN or BECO may offer to buy the
other's interest in the joint venture or sell its own interest in the joint
venture, which gives the offeree the right to elect to buy or sell its interest;
and (5) in the event of a default by the Company in meeting a capital call, BECO
may dilute the Company's interest in the joint venture. The Amended and Restated
Operating Agreement (the "Starpower Operating Agreement") for Starpower
provides, among other things, that (1) so long as each partner maintains a 50%
interest in the joint venture, all business actions require the approval of the
operating committee; (2) subject to certain exceptions, neither RCN nor Pepco
Communications may sell any interest in Starpower within the first four years
after the execution of the Starpower Operating Agreement nor may they thereafter
sell any interest in Starpower without satisfying certain conditions; (3) upon a
change of control of RCN Washington or Pepco Communications, which the other
party has reason to believe will have a material adverse effect on Starpower,
the other party may offer to buy out the entity experiencing the change of
control or to sell its own interest in the joint venture, which gives the
offeree the right to elect to buy or sell its interest or accept the change of
control; (4) after three years following the execution of the agreement, upon
certain deadlock events (defined generally as an inability of the operating
committee to agree upon any business actions), either RCN Washington or Pepco
Communications may offer to buy the other's interest in the joint venture or
sell its own interest in the joint venture, which gives the offeree the
obligation to elect to buy or sell its interest; and (5) failure to make
scheduled capital contributions or to vote in favor of certain additional
capital contributions may result in dilution of equity interests. Accordingly,
certain matters beyond the control of the Company, such as a change of control
of RCN or an inability to agree on certain proposed actions, could result in it
being forced to sell its interest in the relevant joint venture or buy out the
interest of the other joint venturer. There can be no assurance that these
provisions will not have a material adverse effect upon the Company's liquidity
or future prospects or that, if necessary, the Company will be able to raise the
necessary funds to acquire the balance of the interests in the joint venture on
a timely basis and thereby maintain its interest in the venture in question. See
"Business--Strategic Relationships." In addition, although certain covenants
contained in the indentures applicable to the 1997 Notes (the "1997 Notes
Indentures") and the Indenture are applicable to the joint venture companies,
neither the joint venture companies nor the Company's joint venture partners are
parties to the 1997 Notes Indentures or the Indenture and accordingly are not
bound to comply with the terms of the 1997 Notes Indentures or the Indenture. A
disagreement with its joint venture partners over certain business actions,
including actions related to compliance with the 1997 Notes Indentures or the
Indenture, could give rise to a deadlock event.

Competition

     RCN competes with a wide range of service providers for each of the
services that it provides. Virtually all markets for voice and video services
are extremely competitive, and RCN expects that competition will intensify in
the future. In each of the markets in which it offers voice and video
programming services, RCN faces significant competition often from larger,
better-financed incumbent local telephone carriers and cable companies, and RCN
often competes directly with incumbent providers which have historically
dominated their respective local telephone and cable television markets. These
incumbents presently have numerous advantages as a result of their historic
monopoly control of their respective markets.

     With respect to local telephone services, RCN competes with the incumbent
LECs, and alternative service providers including competitive local exchange
carriers ("CLECs") and cellular and other wireless telephone service providers.
With respect to long distance telephone services, RCN faces, and expects to
continue to face, significant competition from the interexchange carriers
("IXCs"), including AT&T, Sprint and MCI, which account for the majority of all
long distance revenue. Certain of the IXCs, including AT&T, MCI and Sprint, have
announced their intention to offer local services in major U.S. markets using
their existing infrastructure in combination with resale of incumbent LEC
service, lease of unbundled local loops or other providers' services.

     All of the Company's video services face competition from alternative
methods of receiving and distributing television signals and from other sources
of news, information and entertainment. Among the alternative video distribution
technologies are home satellite dish earth stations, private satellite master
antenna television systems, direct broadcast satellite services ("DBS") and
wireless program distribution services such as multi-channel multipoint
distribution service systems. The Company expects that its video programming
service will face growing competition from current and new DBS service
providers.

     RCN believes that among the existing competitors, the incumbent LECs and
the incumbent cable providers provide the most direct competition to RCN in the
delivery of "last mile" connections to residential consumers for voice and video
services. In each of its target markets for advanced fiber optic networks, RCN
faces, and expects to continue to face, significant competition from the
incumbent LECs (including Bell Atlantic in New York City and Boston), which
currently dominate their local telephone markets. RCN competes with the
incumbent LECs in its markets for local exchange services on the basis of
product offerings (including the ability to offer bundled voice and video
services), reliability, state-of-the-art technology and superior customer
service, as well as price. The incumbent LECs have begun to expand the amount of
fiber facilities in their networks and to prepare to re-enter into the long
distance telephone services market and, in addition, have long-standing
relationships with their customers. The Company expects that the increased
competition made possible by regulatory reform will result in certain pricing
and margin pressures in the telecommunications services business.

     The Telecommunications Act of 1996 (the "1996 Act") permits the incumbent
LECs and others to provide a wide variety of video services directly to
subscribers in competition with RCN. Various LECs currently are providing video
services within and outside their telephone service areas through a variety of
distribution methods, including both the deployment of broadband wire facilities
and the use of wireless transmission facilities. The Company cannot predict the
likelihood of success of video service ventures by LECs or the impact on the
Company of such competitive ventures.

     Certain of RCN's video programming service businesses compete with
incumbent wireline cable companies in their respective service areas. In
particular, RCN's advanced fiber optic networks compete for cable subscribers
with the major wireline cable operators in New York City and Boston, primarily
Time Warner Cable in New York City and Cablevision in Boston. RCN's wireless
video service in New York City competes with Time Warner Cable, Cablevision
Systems and Comcast. RCN's Pennsylvania hybrid fiber/coaxial cable television
system competes with an alternate service provider, Service Electric Cable TV,
which also holds a franchise for the relevant service area.

     RCN also faces, and expects to continue to face, competition from other
potential competitors in certain of the markets in which RCN offers its
services. Other CLECs, such as Teleport Communications Group, compete for local
telephone services, although they have to date focused primarily on the market
for commercial customers. In addition, potential competitors capable of offering
private line and special access services also include other smaller long
distance carriers, cable television companies, electric utilities, microwave
carriers, wireless telephone system operators and private networks built by
large end-users, including Winstar, Dualstar and New Vision. Cellularvision, a
provider of local multipoint distribution service ("LMDS"), offers wireless
Internet and video programming services in New York City and has announced plans
to offer telephone service in the future.

     The market for Internet access services is extremely competitive and highly
fragmented. No significant barriers to entry exist, and accordingly competition
in this market is expected to intensify. The Company competes (or in the future
may compete) directly or indirectly with (i) national and regional ISPs; (ii)
established online services; (iii) computer software and technology companies;
(iv) national telecommunications companies; (v) LECs; (vi) cable operators; and
(vii) nonprofit or educational ISPs, and some of these present or potential
future competitors have or can be expected to have substantially greater market
presence and financial, technical, marketing and other resources than the
Company. Certain of the Company's online competitors, including America Online,
Inc. ("America Online"), the Microsoft Network and Prodigy, have introduced
unlimited access to the Internet and their proprietary content at flat rates,
and certain of the LECs have also introduced competitive flat-rate pricing for
unlimited access (without a set-up fee for at least some period of time). Bell
Atlantic has recently filed with the Federal Communications Commission (the
"FCC") a petition for an exemption from a regulation prohibiting it from
building a high-speed network. Bell Atlantic's petition requests that such
network, which would serve as an Internet backbone, not be subject to pricing
and other regulatory restriction. The network would span the states from Maine
to Virginia. There can be no assurance that competition will not lead to pricing
pressures in the Internet business. For additional information on the
competitive environment in which the Company operates, see
"Business--Competition."

     Other new technologies may become competitive with services that RCN
offers. Advances in communications technology as well as changes in the
marketplace and the regulatory and legislative environment are constantly
occurring. In addition, a continuing trend toward business combinations and
alliances in the telecommunications industry may also create significant new
competitors to RCN. The Company cannot predict whether competition from such
developing and future technologies or from such future competitors will have a
material impact on its operations.

Regulation

     The telephone and video programming transmission services offered by the
Company are subject to federal, state, and local government regulation. The 1996
Act, which became effective in February 1996, introduced widespread changes in
the regulation of the communications industry, including the local telephone,
long distance telephone, data services, and television entertainment segments in
which the Company operates.

     The 1996 Act eliminates many of the pre-existing legal barriers to
competition in the telephone and video programming communications businesses,
preempts many of the state barriers to local telephone service competition that
previously existed in state and local laws and regulations, and sets basic
standards for relationships between telecommunications providers.

     Among other things, the 1996 Act removes barriers to entry in the local
exchange telephone market by preempting state and local laws that restrict
competition and by requiring LECs to provide nondiscriminatory access and
interconnection to potential competitors, such as cable operators, wireless
telecommunications providers, and long distance companies. In addition, the 1996
Act provides relief from the earnings restrictions and price controls that have
governed the local telephone business for many years. The 1996 Act will also,
once certain thresholds are met, allow Regional Bell Operating Companies
("RBOCs") to enter the long distance market within their own local service
regions.

     Regulations promulgated by the FCC under the 1996 Act require LECs to open
their telephone networks to competition by providing competitors
interconnection, access to unbundled network elements and retail services at
wholesale rates. Numerous parties appealed certain aspects of these regulations,
and the appeals were consolidated in the United States Court of Appeals for the
Eighth Circuit. On July 18, 1997, the Eighth Circuit found constitutional
challenges to certain practices implementing cost provisions of the
Telecommunications Act that were ordered by certain state public utility
commissions ("PUCs") to be premature; vacated significant portions of the FCC's
nationwide pricing rules; and confined the use of combined unbundled network
elements to instances where the requesting carrier itself would do the
combining. On October 14, 1997, the Eighth Circuit issued a decision vacating
additional FCC rules that will likely have the effect of increasing the cost of
obtaining the use of combinations of an incumbent LEC's unbundled network
elements. On January 26, 1998, the Supreme Court granted a writ of certiorari
under which it will review the July 18 Eighth Circuit decision; it is expected
(but not yet certain) that the Court will hear arguments on this case in the
fall of 1998. The Eighth Circuit decisions create uncertainty about the rules
governing pricing and terms and conditions of interconnection agreements, and
could make negotiating and enforcing such agreements more difficult and
protracted and may require renegotiation of existing agreements. Prior to the
Eighth Circuit decisions, the Company had entered into interconnection
agreements with Bell Atlantic, covering all of its target market area, that are
generally consistent with the FCC guidelines, and those agreements remain in
effect notwithstanding the reversal of the FCC rules. There can be no assurance,
however, that the Company will be able to obtain or enforce future
interconnection agreements, or obtain renewal of existing agreements, on terms
acceptable to the Company.

     Certain RBOCs have also raised constitutional challenges to restrictions in
the 1996 Act preventing BOCs from entering the long distance market in their
home region. On December 31, 1997, the U.S. District Court for the Northern
District of Texas issued a decision (the "SBC Decision") finding that Sections
271 to 275 of the Telecommunications Act of 1996 are unconstitutional. SBC
Communications, Inc., et al. v. Federal Communications Commission, et al., Civil
Action No. 7:97-CV-163-X. These sections of the 1996 Act impose restrictions on
the lines of business in which the RBOCs may engage, including establishing the
conditions they must satisfy before they may provide in-region interLATA
telecommunications services. The District Court has stayed the SBC Decision
pending appeal. If the stay is lifted, the RBOCs (including Bell Atlantic, which
was permitted to intervene in the case) would be able to provide interLATA
services immediately without satisfying the statutory conditions. Although the
Company believes the factual assumptions and legal reasoning in the SBC Decision
are erroneous and therefore the decision will likely be reversed on appeal,
there can be no assurance of this outcome. If the SBC Decision were upheld on
appeal it may have an unfavorable effect on the Company's business for at least
two reasons. First, RBOCs currently have an incentive to foster competition
within their service areas so that they can qualify to offer interLATA services.
The SBC Decision removes this incentive by allowing RBOCs to offer interLATA
service without regard to their progress in opening their local markets to
competition. However, the SBC Decision would not affect other provisions of the
Act which create legal obligations for all incumbent LECs to offer
interconnection and network access, and therefore will not impair the Company's
ability to compete in local exchange markets. Second, the Company is legally
able to offer its customers both long distance and local exchange services,
which the RBOCs currently may not do. This ability to offer "one-stop shopping"
gives the Company a marketing advantage that it would no longer enjoy if the SBC
Decision were upheld on appeal. The Company cannot predict either the outcome of
these or future challenges to the 1996 Act, any related appeal of regulation or
court decision, or the eventual effect on its business or the industry in
general.

     The 1996 Act also makes far-reaching changes in the regulation of the video
programming transmission services offered by RCN, including changes to the
regulations applicable to video operators, the elimination of restrictions on
telephone company entry into the video business, and the establishment of a new
"open video systems" ("OVS") regulatory structure for telephone companies and
others to offer such services. Under the 1996 Act, local telephone companies,
including both incumbent LECs such as Bell Atlantic, and CLECs such as RCN, may
provide service as traditional cable television operators subject to municipal
cable television franchises, or they may opt to provide their programming over
non-franchised open video systems subject to certain conditions, including, but
not limited to, making available a portion of their channel capacity for use by
unaffiliated program distributors and satisfying certain other requirements,
including providing capacity for public, educational and government channels,
and payment of a gross receipts fee equivalent to the franchise fee paid by the
incumbent cable television operator. RCN is one of the first CLECs to provide
television programming over an advanced fiber optic network pursuant to the OVS
regulations implemented by the FCC under the 1996 Act. As discussed below, RCN
is currently providing OVS service in the City of Boston and the City of New
York, and has entered into an OVS agreement to allow it to provide OVS services
in a number of communities surrounding Boston. Starpower is negotiating similar
agreements in Washington and surrounding communities.

     RCN's voice business is subject to regulation by the FCC at the federal
level with respect to interstate telephone services (i.e., those that originate
in one state and terminate in separate states). State regulatory commissions
have jurisdiction over intrastate communications (i.e., those that originate and
terminate in the same state). See "Business--Regulation--Regulation of Voice
Services." Municipalities also regulate limited aspects of RCN's voice business
by, for example, imposing various zoning requirements and, in some instances,
requiring telecommunications licenses, franchise agreements and/or installation
permits for access to local streets and rights-of-way. In New York City, for
example, RCN will be required to obtain a telephone franchise in order to
provide voice services using its advanced fiber optic network facilities located
in the streets of New York City.

     In February 1997, RCN subsidiaries were certified to operate OVS networks
in the five boroughs of New York City and, as part of a joint venture with
Boston Edison, in Boston and 47 surrounding communities. Initiation of OVS
services is subject to negotiation of certain agreements with local governments.
RCN executed an agreement with the City of Boston on June 2, 1997, and initiated
OVS service in the City on that day. Pursuant to its agreement with the City of
Boston, RCN will be required to pay a fee to the City equal to 5% of video
revenues. RCN has entered into similar OVS agreements or is in the process of
negotiating agreements with certain other Boston-area municipalities, either to
offer OVS services or franchised cable television services. It executed an
agreement with the City of New York on December 29, 1997, and has initiated OVS
service in the Borough of Manhattan pursuant to that agreement.

     In areas where it offers video programming services as an OVS operator, RCN
is required to hold a 90-day open enrollment period every three years, during
which times RCN will be required to offer capacity on its network to other video
programming providers ("VPPs"). Under the OVS regulations, RCN must offer at
least two-thirds of its capacity to unaffiliated parties, if demand for such
capacity exists during the open enrollment period. In certain areas, RCN is in
discussions with local municipal authorities to explore the feasibility of
obtaining a cable franchise in lieu of an OVS agreement, and will consider
providing RCN video service pursuant to franchise agreements rather than OVS
certification, if franchise agreements can be obtained on terms and conditions
acceptable to RCN. However, RCN will consider the relative benefits of OVS
certification versus local franchise agreements, including the possible
imposition of universal service requirements, before making any such decisions.
In addition, the current FCC rules concerning OVS are subject to appeal in the
United States Court of Appeals and, to the extent that certain favorable aspects
of the FCC's rules are overturned on appeal, the determination of whether to
operate as an OVS provider versus as a franchised cable television operator may
be affected. Moreover, the incumbent cable television provider in Boston,
Cablevision Systems, has requested that the FCC permit it to obtain capacity on
RCN's Boston area OVS network, and Time Warner, the incumbent cable television
provider in certain communities in the Boston area, has made a similar filing at
the FCC with respect to its request for capacity on the Boston OVS network. RCN
will continue to oppose these requests made to the FCC, but to the extent that
the FCC were to grant any such request(s), such a result would likely affect the
Company's determination as to whether to operate as an OVS provider versus as a
franchised cable television operator.

     Prior to its certification as an OVS provider, RCN offered limited video
programming services using the video dialtone ("VDT") services offered by
MFS/WorldCom in Manhattan and the City of Boston. In February, 1997, the FCC
held that MFS/WorldCom's facilities did not qualify as video dialtone facilities
entitled to an extension of time to comply with the newly-adopted OVS rules;
nonetheless, the FCC did not direct MFS/WorldCom and RCN to cease video
programming distribution operations over the MFS/WorldCom platform. One of the
incumbent cable television companies in New York City has filed a complaint with
the New York Public Service Commission challenging the former (pre-OVS)
operations of RCN and WorldCom under the VDT framework, which remains pending
before that Commission.

     RCN's 18 GHz wireless video services in New York City are distributed using
microwave facilities provided by Bartholdi Cable Company ("Bartholdi Cable")
pursuant to temporary authorizations issued to Bartholdi Cable by the FCC.
Bartholdi Cable has agreed to provide transmission services to RCN until RCN has
either converted the wireless video subscribers to its advanced fiber optic
network facilities or has obtained FCC authority to provide such services
pursuant to its own wireless radio licenses. In addition, Bartholdi Cable has
agreed to transfer to RCN the transmission equipment on demand. Bartholdi
Cable's obligation to provide transmission services is subject to Bartholdi
Cable having licenses from the FCC to provide such services. The qualifications
of Bartholdi Cable to hold certain of the licenses needed to provide
transmission services to RCN are at issue in an FCC proceeding in which an
initial decision (the "Initial Decision") was released on March 6, 1998. In the
Initial Decision, the Administrative Law Judge found Bartholdi Cable unqualified
with respect to 15 such licenses. The Initial Decision will become effective 50
days after its release unless Bartholdi Cable, as expected, files exceptions to
the Initial Decision within 30 days of its release or the FCC elects to review
the case on its own motion. Because of the uncertainty as to Bartholdi Cable's
right in the future to offer transmission services to RCN, the Company filed its
own license applications at the FCC for all of the microwave transmission paths
which are currently being used by Bartholdi Cable to provide transmission
services to RCN and, in light of the increased uncertainties resulting from the
Initial Decision in the FCC proceeding involving certain of Bartholdi Cable's
licenses, the Company expects now actively to pursue its license applications.
While the Company expects to receive authorizations to transmit over these
microwave paths, there can be no assurance that RCN will be able to offer
wireless video services pursuant to its own FCC licenses or that the FCC's
investigation will be resolved favorably. The failure to obtain such license or
resolve such proceedings would materially adversely affect the Company's
wireless video operations in New York City.

     There can be no assurance that RCN will be able to obtain or retain all
necessary authorizations needed to construct advanced fiber optic network
facilities in order to convert its wireless video subscribers to an advanced
fiber optic network.

     RCN's hybrid fiber/coaxial cable systems are subject to regulation under
the Cable Television Consumer Protection and Competition Act of 1992, as amended
(the "1992 Act"), which provides, among other things, for rate regulation for
cable services in communities that are not subject to "effective competition."
On September 8, 1997, the Company was notified by the FCC that it has ruled that
certain of the Company's upper levels of service for its New Jersey systems are
regulated levels of service and that the Company's rates for such levels of
service have exceeded the allowable rates under the FCC rate regulation rules
which have been effective since September 1993. The Company had treated these
levels of service as unregulated. The Company intends to contest this decision.
The Company does not believe that the ultimate resolution of this matter will
have a material impact on its results of operations or financial condition. With
the passage of the 1996 Act all cable systems rates will be deregulated as
effective competition is shown to exist in the franchise area, or by March 31,
1999, whichever date is sooner. RCN anticipates that the remaining provisions of
the 1992 Act that do not relate to rate regulation, such as the provisions
relating to retransmission consent and customer service standards, will remain
in place and may serve to reduce the future operating margins of RCN's hybrid
fiber/coaxial cable television businesses as video programming competition
develops in its cable television service markets. Federal requirements also
impose certain broadcast signal carriage requirements that allow local
commercial television broadcast stations to require a cable system to carry the
station, and that require cable operators to set aside certain channels for
public, educational and governmental access programming. Because a cable
communications system uses local streets and rights-of-way, such cable systems
are generally subject to state and local regulation, typically imposed through
the franchising process. The terms and conditions of state or local government
franchises vary materially from jurisdiction to jurisdiction and generally
contain provisions governing cable service rates, franchise fees, franchise
term, system construction and maintenance obligations, customer service
standards, franchise renewal, sale or transfer of the franchise, territory of
the franchisee and use and occupancy of public streets and types of cable
services provided.

     RCN's ability to provide franchised cable television services is dependent
on its ability to obtain and renew its franchise agreements from local
government authorities on generally acceptable terms. RCN currently has 91
franchise agreements relating to the hybrid fiber/coaxial cable systems'
networks in New York (outside New York City), New Jersey and Pennsylvania. These
franchises typically contain many conditions, such as time limitations on
commencement and completion of construction, conditions of service, including
the number of channels, the provision of free service to schools and certain
other public institutions, and the maintenance of insurance and indemnity bonds.
These franchises provide for the payment of fees to the issuing authorities and
generally range from 3% to 5% of revenues. The duration of these outstanding
franchises presently varies up to the year 2011. To date, all of RCN's cable
franchises have been renewed or extended, generally at or prior to their stated
expirations and on acceptable terms. Approximately 39 of RCN's hybrid
fiber/coaxial cable system's franchises are due for renewal within the next
three years. No assurances can be given that RCN will be able to renew its
franchises on acceptable terms. No one franchise accounts for more than 7% of
RCN's total revenue. RCN's five largest franchises account for approximately 27%
of RCN's total revenue.

     The data services business, including Internet access, is largely
unregulated at this time (apart from Federal, state, and local laws and
regulations applicable to businesses in general). However, there can be no
assurance that this business will not become subject to regulatory restraints.
Some jurisdictions have sought to impose taxes and other burdens on providers of
data services, and to regulate content provided via the Internet and other
information services. RCN expects that proposals of this nature will continue to
be debated in Congress and state legislatures in the future. In addition,
although the FCC has on several occasions rejected proposals to impose
additional costs on providers of Internet access service and other data services
to the extent they use local exchange telephone network facilities for access to
their customers, similar proposals may well be considered by the FCC or Congress
in the future. See "--Potential Liabilities Associated with Internet
Businesses."

     The foregoing does not purport to describe all present and proposed
federal, state, and local regulations and legislation affecting the telephone
and video programming industries. Other existing federal regulations, copyright
licensing, and, in many jurisdictions, state and local franchise requirements,
are currently the subject of judicial proceedings, legislative hearings and
administrative proposals which could change, in varying degrees, the manner in
which communications companies operate. The ultimate outcome of these
proceedings, and the ultimate impact of the 1996 Act or any final regulations
adopted pursuant to the new law on RCN or its businesses cannot be determined at
this time. For additional information on the regulatory environment in which the
Company operates, see "Business--Regulation."

Need to Obtain and Maintain Permits, Building Access Agreements and 
Rights-of-Way

     In order to develop its networks, the Company must obtain local franchises
and other permits, as well as building access agreements and rights to utilize
underground conduit and pole space and other rights-of-way and fiber capacity
from entities such as incumbent LECs and other utilities, railroads, long
distance companies, state highway authorities, local governments and transit
authorities. There can be no assurance that the Company will be able to maintain
its existing franchises, permits and rights or to obtain and maintain the other
franchises, permits, building access agreements and rights needed to implement
its business plan on acceptable terms. Although the Company does not believe
that any of the existing arrangements will be canceled or will not be renewed as
needed in the near future, cancellation or non-renewal of certain of such
arrangements could materially adversely affect the Company's business in the
affected area. In addition, the failure to enter into and maintain any such
required arrangements for a particular network, including a network which is
already under development, may affect the Company's ability to acquire or
develop that network.

Ability to Procure Programming Services

     The Company's video programming services are dependent upon management's
ability to procure programming that is attractive to its customers at reasonable
commercial rates. The Company is dependent upon third parties for the
development and delivery of programming services. These programming suppliers
charge the Company for the right to distribute the channels to the Company's
customers. The costs to the Company for programming services is determined
through negotiations with these programming suppliers. Management believes that
the availability of sufficient programming on a timely basis will be important
to the Company's future success. There can be no assurance that the Company will
have access to programming services or that management can secure rights to such
programming on commercially acceptable terms.

Liabilities for Unearned Revenues

     Erols offers one-, two- and three-year subscriptions for Internet access,
which generally are paid for in advance. Such subscriptions are subject to
cancellation with a full refund for the first 30 days and to cancellation with a
pro-rated refund thereafter. Such revenues will be recognized over the term of
each such subscription, resulting in material short-and long-term liabilities
for unearned revenues. As of December 31, 1996, Erols had short- and long-term
liabilities for unearned revenues of approximately $12.9 million and $3.4
million, respectively and, as of December 31, 1997, of approximately $25.6
million and $8.9 million, respectively. Cancellation by a significant number of
the subscribers under such contracts could require cash payment of material
sums.

Variability of Operating Results

     As a result of factors such as the significant expenses associated with the
development of its networks and services, the Company anticipates that its
operating results could vary significantly from period to period.

Risks Relating to Provision of Internet Services

     Dependence on the Internet; Uncertain Acceptance of the Internet as a
Medium of Commerce and Communication. The Company's Internet business will
depend in part upon the continuing development and expansion of the Internet and
the market for Internet access. Important issues concerning business and
personal use of the Internet (including security, reliability, cost, ease of
use, access and quality of service) remain unresolved and may significantly
affect the growth of Internet use. Acceptance of the Internet for commerce and
communications generally requires that potential users accept a new way of
conducting business and exchanging information, industry participants continue
to provide new and compelling content and applications, and the Internet provide
a reliable and secure computer platform. A diminution in the growth of demand
for Internet services or an absolute decrease in such demand could have a
material adverse effect on the Company's Internet business.

     Evolving Industry Standards. New industry standards have the potential to
replace or provide lower-cost alternatives to existing services. The adoption of
such new industry standards could render the Company's existing services
obsolete and unmarketable or require reduction in the fees charged therefor. For
example, Erols' services currently rely on the widespread commercial use of
Transmission Control Protocol/Internet Protocol ("TCP/IP"). Alternative open and
proprietary protocol standards that compete with TCP/IP, including proprietary
protocols developed by International Business Machines Corporation ("IBM") and
Novell, Inc. have been or are being developed.

     ISPs participate in the Internet through contractual "peering arrangements"
with Internet companies. These contractual arrangements are not subject to
regulation and could be subject to revision in terms, conditions or costs over
time.

     Constraints on Capacity and Supply of Equipment. The Company's ability to
provide Internet service will depend in part on its ability to provide
sufficient capacity, both at the level of particular POPs (affecting only
subscribers attempting to use that POP) and in connection with system-wide
services (such as e-mail and news services, which can effect all subscribers).
In addition, the Company will be dependent in part on the availability of
equipment such as modems, servers and other equipment. Any shortage of such
equipment or capacity of servers could result in a strain on incoming access
lines during peak times, causing busy signals and/or delays for subscribers.

     Reliance on Network Infrastructure; Risk of System Failure; Security Risks.
Internet network infrastructure is vulnerable to computer viruses and other
similar disruptive problems caused by its users, other Internet users or other
third parties. Computer viruses and other problems could lead to interruptions
of, delays in, or cessation of service, by the Company, as well as corruption of
the Company's or its subscribers' computer systems. In addition, there can be no
assurance that subscribers or others will not assert claims of liability against
the Company as a result of events such as computer viruses, other inappropriate
uses or security breaches.

     Proprietary Rights; Risk of Infringement. Erols relies on a combination of
copyright, trademark and trade secret laws and contractual restrictions to
establish and protect its proprietary technology. However, there can be no
assurance that Erols' technology will not be misappropriated or that equivalent
or superior technologies will not be developed. In addition, there can be no
assurance that third parties will not assert that the Erols' services or its
users' content infringe their proprietary rights.

     The Company has obtained authorization, typically in the form of a license,
to distribute third-party software incorporated in the Erols access software
product for Windows 3.1, Windows 95, Windows NT and Macintosh platforms. The
Company plans to maintain or negotiate renewals of existing software licenses
and authorizations. The Company may want or need to license other applications
in the future.

Potential Liabilities Associated with Internet Businesses

     Prior to the enactment of the Communications Decency Act of 1996 (the
"CDA"), which is Title V of the 1996 Act, a federal district court held that an
online service provider could be found liable for defamation, on the ground that
the service provider exercised active editorial control over postings to its
service. The CDA contains a provision which, one court has held, shields ISPs
from such liability for material posted to the Internet by their subscribers or
other third parties. Other courts have held that online service providers and
ISPs may, under certain circumstances, be subject to damages for copying or
distributing copyrighted materials.

     As enacted, the CDA imposed fines on any entity that (i) by means of a
telecommunications device, knowingly sends indecent or obscene material to a
minor; (ii) by means of an interactive computer service, sends or displays
indecent material to a minor; or (iii) permits any telecommunications facility
under such entity's control to be used for the foregoing purposes. That
provision, as applied to indecent materials, has been declared unconstitutional
by the United States Supreme Court. While the Clinton Administration has
announced that it will not seek passage of similar legislation to replace this
provision, action by Congress in this area remains possible. At present, the
Company intends to exercise editorial control over Internet postings to the
extent of blocking Web sites and Usenet News groups when the Company becomes
aware that such sites or groups offer child pornography.

     As the law in this area develops, the potential that liability might be
imposed on the Company for information carried on and disseminated through its
network could require the Company to implement measures to comply with
applicable law and reduce its exposure to such liability, which could require
the expenditure of substantial resources or the discontinuation or modification
of certain service offerings.

Reliance on Key Personnel

     The Company believes that its continued success will depend in large part
on its ability to attract and retain highly skilled and qualified personnel. The
Company believes that the Distribution will, among other things, permit the
Company to offer equity-based compensation that is more directly linked to the
Company's performance, which the Company believes will facilitate the
attraction, retention and motivation of highly skilled and qualified personnel.
In this regard, the Company has implemented an Employee Stock Ownership Plan
("ESOP") and makes available competitive employee benefit programs providing
benefits substantially comparable to benefits provided immediately prior to the
Distribution. There can be no assurance that the Company will retain or, as
necessary, attract qualified management personnel.

Conflicts of Interest

     As a result of the Distribution, there exist relationships that may lead to
conflicts of interest. Level 3 Telecom Holdings, Inc. ("Kiewit Telecom"),
formerly Kiewit Telecom Holdings, Inc., effectively controls the Company,
Commonwealth Telephone and Cable Michigan. In addition, the majority of the
Company's named executive officers are also directors and/or executive officers
of Commonwealth Telephone or Cable Michigan. See "Management." In particular,
David C. McCourt, Chairman and Chief Executive Officer of the Company, has
served as a director and Chairman and Chief Executive Officer of Cable Michigan
since the Distribution and will remain as a director and Chairman and Chief
Executive Officer of Commonwealth Telephone. Mr. McCourt expects to devote
approximately 70% of his time to managing the affairs of the Company. In
addition, Michael J. Mahoney, who has been President and Chief Operating
Officer, as well as a director, of the Company since the Distribution, is also a
director of Commonwealth Telephone. Mr. Mahoney expects to devote approximately
85-90% of his time to managing the affairs of the Company. The Company's other
named executive officers expect to devote the following approximate portions of
their time to managing the affairs of the Company: Mr. Godfrey (80%); Mr.
Haverkate (75%) and Mr. Adams (100%). The success of the Company may be affected
by the degree of involvement of its officers and directors in the Company's
business and the abilities of the Company's officers, directors and employees in
managing both the Company and the operations of Cable Michigan and/or
Commonwealth Telephone. Potential conflicts of interest will be dealt with on a
case-by-case basis taking into consideration relevant factors including the
requirements of NASDAQ and prevailing corporate practices.

     In connection with the Distribution, Commonwealth Telephone has agreed to
provide or cause to be provided to the Company and to Cable Michigan certain
specified services for a transitional period after the Distribution. The fees
for such services will be an allocated portion (based on relative usage) of the
cost incurred by Commonwealth Telephone to provide such services to the Company,
Cable Michigan and Commonwealth Telephone. Based on this allocation arrangement,
the fee for such services to the Company would have been approximately $753,000
for 1996. See "Description of the Distribution and Related Agreements--
Transitional Services and Arrangements." The aforementioned arrangements are not
the result of arm's length negotiation between unrelated parties as the Company
and Commonwealth Telephone have certain common officers and directors. Although
the transitional service arrangements in such agreements are designed to reflect
arrangements that would have been agreed upon by parties negotiating at arm's
length, there can be no assurance that the Company would not be able to obtain
better terms from unrelated third parties. Additional or modified agreements,
arrangements and transactions may be entered into between the Company and either
or both of Commonwealth Telephone and Cable Michigan, which will be negotiated
at arm's length.

Absence of Public Market for the Notes; Transfer Restrictions

     The New Notes are being offered to holders of Old Notes. The New Notes are
new securities for which there currently is no established trading market.
Although the Initial Purchasers have informed the Company that they currently
intend to make a market in the Notes, they are not obligated to do so, and any
such market-making may be discontinued at any time without notice. Accordingly,
there can be no assurance as to the development or liquidity of any market for
the Notes. The Company does not intend to apply for listing of the Notes on any
securities exchange or for quotation through NASDAQ. If a trading market
develops for the New Notes, future trading prices of such securities will depend
on many factors, including prevailing interest rates, the Company's results of
operations and financial condition and the market for similar securities.


                              USE OF PROCEEDS

     There will be no proceeds to the Company from the issuance of the New Notes
pursuant to the Exchange Offer. In consideration for issuing the New Notes in
exchange for the Old Notes as described in this Prospectus, the Company will
receive Old Notes in like principal amount. The Old Notes surrendered in
exchange for the New Notes will be retired and canceled. Accordingly, the
issuance of the New Notes will not result in any change in the indebtedness of
the Company. The net proceeds to the company from the sale of the Old Notes was
approximately $345 million after deducting the Initial Purchasers' discount and
estimated expenses payable by the Company. The net proceeds will be used to fund
and support the expansion and interconnection of existing networks and services
and the development and operation of new advanced fiber optic networks.


                              CAPITALIZATION

     The following table sets forth the capitalization of the Company as of
December 31, 1997, (i) on an unaudited historical basis, (ii) on an unaudited
pro forma basis, giving effect to the Acquisition as if it had been consummated
on December 31, 1997, and (iii) on an unaudited pro forma as adjusted basis,
giving effect to the consummation of the Offering. The capitalization table
below should be read in conjunction with the historical Consolidated Financial
Statements and Notes thereto included elsewhere in this Prospectus,
"Management's Discussion and Analysis of Financial Condition and Results of
Operations" and "Unaudited Pro Forma Consolidated Financial Statements." The
unaudited pro forma capitalization presented below is provided for informational
purposes only and should not be construed as indicative of the Company's
capitalization or financial condition had the transactions reflected thereby
been consummated on the date assumed, and may not reflect the capitalization or
financial condition which would have resulted had the Company been operated as a
separate, independent company during such period, and are not necessarily
indicative of the Company's future capitalization or financial condition.

              UNAUDITED PRO FORMA CONSOLIDATED FINANCIAL STATEMENTS

     Prior to September 30, 1997, the Company was operated as part of C-TEC. The
following Unaudited Pro Forma Consolidated Statement of Operations sets forth
the historical statements of operations of the Company for the years ended
December 31, 1997 and 1996 and as adjusted for the Distribution, the issuance of
the 1997 Notes, the Acquisition and the issuance of the Notes offered hereby,
and the related transactions and events described in the notes thereto, as if
such transactions and events had been consummated on the first day of the
respective periods. The following Unaudited Pro Forma Consolidated Balance Sheet
sets forth the historical balance sheet of the Company as of December 31, 1997,
and as adjusted for the transactions and events described in the notes thereto
as if such transactions and events had been consummated on December 31, 1997.

     Management believes that the assumptions used provide a reasonable basis on
which to present such Unaudited Pro Forma Condensed Consolidated Financial
Statements. The Unaudited Pro Forma Consolidated Financial Statements should be
read in conjunction with the historical Financial Statements and notes thereto
included elsewhere in this Prospectus and "Management's Discussion and Analysis
of Financial Condition and Results of Operations." The Unaudited Pro Forma
Consolidated Financial Statements are provided for information purposes only and
should not be construed to be indicative of the Company's results of operations
or financial condition had the Distribution and the transactions and events
described above been consummated on the dates assumed, may not reflect the
results of operations or financial condition which would have resulted had the
Company been operated as a separate, independent Company during such period, and
are not necessarily indicative of the Company's future results of operations or
financial condition.

acquisition of the minority interest of Freedom had occurred at the beginning of
1996.

      (4) Adjustment to eliminate interest income of $8,686 for the year ended
December 31, 1997 and $15,127 for the year ended December 31, 1996, net of
income taxes of $(3,040) for the year ended December 31, 1997 and $(5,294) for
the year ended December 31, 1996, on outstanding intercompany notes payable owed
to the Company of which $110,000 was repaid and the remaining balance was

issuance costs related to the issuance of the 1997 Notes aggregating $50,221 for
the year ended December 31, 1997 and $63,438 for the year ended December 31,

      (8) Adjustment to eliminate interest expense and amortization of debt

the year ended December 31, 1996 and related income taxes of $3,661 for the year

repayment of $5,800 of debt (including payment of accrued interest).
Additionally, the Company is converting approximately 998,719 stock options for
Erols common stock into options to purchase 699,104 shares of RCN Common Stock
at an average exercise price of $3.424 per share. The Company accounted for this
transaction under the purchase method of accounting and accordingly, the
financial statements of Erols are not consolidated with the Company's historical
financial statements as of and for the years ended December 31, 1997 and 1996.
The financial information of Erols was provided by Erols.

     (12) Such adjustments include a pro forma allocation of historical
operating results of Erols to the joint venture with PEPCO (see Note 18) based
upon the relationship of the number of subscribers expected to be contributed to
the joint venture to the total number of subscribers acquired in the merger. The
Company's share of such operating results, including the depreciation and
amortization effects of the allocation of a portion of the total purchase price
to the joint venture, representing the assumed value of the subscribers to be
contributed to the joint venture, are included in the adjustment for "equity in
the loss of unconsolidated entities."

     (13) Such adjustment reflects the increase in depreciation and amortization
for the effect of the fair value adjustment of the net assets of Erols acquired.
See Note 17. Amortization of such excess over a five year period has been
assumed, although a shorter life may result based on the study discussed in Note
17. Also, as discussed in Note 17, a portion of the excess may be allocated to
certain in-process research and development projects. To the extent amounts are
allocated to certain in-process research and development projects, pro forma
amortization expense would be ratably reduced.


                                 RCN CORPORATION
   NOTES TO UNAUDITED PRO FORMA CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

     (14) Adjustment to reflect the tax effect of the pro forma adjustments,
including the tax effect of the historical results of operations of Erols.

     (15) Adjustment to reflect interest expense and amortization of debt
issuance costs related to the issuance of the Notes aggregating $34,958 and
$34,958 for the years ended December 31, 1997 and 1996, respectively, net of
income taxes of $12,235 and $12,235 for the years ended December 31, 1997 and
1996, respectively.

     (16) Adjustment to reflect $29,200 cash portion of the consideration for
the merger and $5,800 of debt (including accrued interest) of Erols outstanding
at December 31, 1997 which the Company repaid at closing.

     (17) The Company allocated the purchase price for Erols (see Note 11) on
the basis of the fair market value of the assets acquired and liabilities
assumed. The Company expects to undertake a study to determine such fair market
values, including in-process research and development. Such fair market values
may differ from the allocations assumed in the pro forma financial statements.
The impact on deferred tax balances was included in the above-referenced fair
value adjustments. Erols' historical property, plant and equipment has been
adjusted to its estimated fair value based upon its depreciated cost. The
remaining excess of consideration over the historical book value of Erols net
assets acquired has been preliminarily allocated to subscriber base, goodwill
and other intangible assets. Additionally, to the extent that a portion of the
purchase price is allocated to in-process research and development, a charge,
which may be material, would be recognized in the period in which the RCN/Erols
merger occurred and ratably reduce the amounts preliminarily allocated to
subscriber base, goodwill and other intangible assets.

     (18) A subsidiary of the Company is a party to a joint venture with a
subsidiary of PEPCO, to provide the greater Washington, D.C. area residents and
businesses local and long-distance telephone, cable television, and Internet
services as a package from a single source. As a result of this joint venture,
the Company expects to contribute to the joint venture the subscribers acquired
in the merger with Erols which are located in the relevant joint venture market.
The joint venture partners of Starpower are currently negotiating the terms of
such contribution. The value of such contribution for accounting purposes is
estimated to be approximately $58,951. The joint venture is accounted for under
the equity method of accounting. As a result, the Company's contribution is
reflected as an increase in "Investments." Additionally, the Company will
allocate the liability for the unearned revenue related to the subscribers
contributed to Starpower.

     (19) Adjustment to reflect the elimination of Erols' deficit and the
issuance of 1,730,648 shares of RCN stock as a portion of the consideration for
the merger. See Note 11.

     (20) Adjustment to reflect the issuance in February 1998 of $350,587 of
9.80% Senior Discount Notes due 2008. The debt issuance costs of $6,000 are
included in "deferred charges and other assets" and are amortized over the term
of the Notes.

     (21) Represents adjustment for shares to be issued in connection with the
acquisition of Erols. See Note 11.

                     MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                  FINANCIAL CONDITION AND RESULTS OF OPERATIONS
                  (Dollars in thousands, except per share data)

     Certain statements contained in this annual report are "forward-looking
statements" within the meaning of the Private Securities Litigation Reform Act
of 1995 and are thus prospective. Such forward-looking statements include, in
particular, statements made as to plans to develop networks and upgrade
facilities, the market opportunity presented by markets targeted by the Company,
the Company's intention to connect certain wireless video resale telephone and
Internet service customers to its advanced fiber optic networks, the development
of the Company's businesses, the markets for the Company's services and
products, the Company's anticipated capital expenditures, the Company's
anticipated sources of capital and effects of regulatory reform and competitive
and technological developments. No assurance can be given that the future
results covered by the forward looking statements will be achieved. Such
statements are subject to risks, uncertainties and other factors which could
cause actual results to differ materially from future results expressed or
implied by such forward-looking statements.

     The following discussion should be read in conjunction with the Company's
historical Consolidated Financial Statements and Notes thereto:

General

     The Company is developing networks that are capable of providing a full
range of high speed, high capacity telecommunications services, including voice,
video programming and data services including Internet access. The Company
intends to provide these services individually or in bundled service packages
primarily to residential customers in high-density areas and also seeks to serve
certain commercial accounts on or near its networks. In 1997, the Company
commenced providing service through advanced fiber optic network facilities in
New York City and Boston. The Company also has hybrid fiber/coaxial cable
television operations in New York (outside New York City), New Jersey and
Pennsylvania ("Hybrid Fiber/Coaxial"), wireless video operations in New York
City ("Wireless Video"), and certain other operations, including long distance
telephone (collectively, "Other Operations"). The Company has historically
managed its business along these lines and the discussion which follows
addresses those lines accordingly.

     Financial results related to advanced fiber optic networks and from
provision of Internet services are currently included in the "Advanced Fiber,
Wireless Video and Other Operating" segment data. The Company may present
separate segment information with respect to the advanced fiber optic networks
and Internet business in future periods in connection with the Company's
adoption of Statement of Financial Accounting Standards No. 131 -- "Disclosure
about Segments of an Enterprise and Related Information." The Company expects
that the operating and net losses and negative cash flows from its advanced
fiber optic network business will rise in the future as it expands and develops
its network and customer base. There can be no assurance that RCN will achieve
or sustain profitability or positive cash flows from operating activities in the
future as it develops its advanced fiber optic network.

     The negative operating cash flow from the Company's advanced fiber optic
network business has resulted primarily from expenditures associated with the
development of the Company's operational infrastructure and marketing expenses.
The Company expects it will continue to experience negative operating cash flow
while it continues to invest in its networks and until such time as revenue
growth is sufficient to fund operating expenses. The Company expects to achieve
positive operating margins over time by (i) increasing the number of customers
it serves, (ii) increasing the number of connections per customer by cross
marketing its services and promoting bundled service options and therefore
increasing the revenue per customer, (iii) lowering the costs associated with
new subscriber additions and (iv) reducing the cost of providing services by
capturing economies of scale. The Company expects its operating revenues will
increase in 1998 through internal growth of its current advanced fiber optic
networks; however, the Company also expects negative operating cash flow will
increase for some period of time as the Company initiates network development in
Washington, D.C. and expands its current networks. When the Company makes its
initial investment in a new market, the operating losses typically increase as
the network and sales force are expanded to facilitate growth. The Company's
ability to generate positive cash flow in the future will depend on the extent
of capital expenditures in current and additional markets, the ability of the
joint ventures to generate revenues and cash flow, competition in the Company's
markets and any potential adverse regulatory developments. The Company will be
dependent on various financing sources to fund its growth as well as continued
losses from operations. There can be no assurance that such funding will be
available, or available on terms acceptable to the Company. See "--Liquidity and
Capital Resources."

     The terms of the Company's joint ventures require the mutual consent of the
Company and its joint venture partner to distribute or advance funds to the
Company. The Company's debt agreements allow subsidiaries and joint ventures to
incur indebtedness for network buildout costs, which indebtedness may contain
limitations on the subsidiaries' and the joint venture's ability to pay
dividends and distributions to the Company. Although the joint ventures have not
had a significant impact on the Company's cash flows in the periods presented,
cash flows available to the Company in future periods will be affected by the
extent to which operations are conducted through joint ventures. Due to the
degree of control that the Company has in the joint ventures, RCN accounts for
the BECO joint venture on a consolidated basis and Starpower under the equity
method of accounting.

     Prior to September 30, 1997, the Company was operated as part of C-TEC. On
September 30, 1997, C-TEC distributed 100% of the outstanding shares of common
stock of its wholly owned subsidiaries, RCN and Cable Michigan to holders of
record of C-TEC's Common Stock and C-TEC's Class B Common Stock as of the close
of business on September 19, 1997 in accordance with the terms of a Distribution
Agreement dated September 5, 1997 among C-TEC, RCN and Cable Michigan (the
"Distribution Agreement"). RCN consists primarily of C-TEC's bundled residential
voice, video and Internet access operations in the Boston to Washington, D.C.
corridor, its existing New York, New Jersey and Pennsylvania cable television
operations, a portion of its long distance operations and its international
investment in Megacable. C-TEC , RCN and Cable Michigan have entered into
certain agreements providing for the Distribution, and governing various ongoing
relationships between the three companies, including a distribution agreement
and a tax-sharing agreement. The historical financial information presented
herein reflects periods during which the Company did not operate as an
independent company and accordingly, certain assumptions were made in preparing
such financial information. Such information, therefore, may not necessarily
reflect the results of operations or the financial condition of the Company
which would have resulted had the Company been an independent, public company
during the reporting periods, and are not necessarily indicative of the
Company's future operating results or financial condition.

     Certain of the Company's businesses were acquired by C-TEC and transferred
to the Company in connection with the Distribution. On August 30, 1996, a
subsidiary of C-TEC acquired an 80.1% interest in Freedom and all related rights
and liabilities from Kiewit Telecom. Freedom held the wireless cable television
business of Liberty Cable. The Company acquired the remaining minority interest
in Freedom in March 1997. The acquisition was accounted for as a purchase and is
reflected in the Company's consolidated financial statements since September
1996. On May 15, 1995, C-TEC Cable Systems, Inc., a wholly owned subsidiary of
C-TEC ("RCN Cable"), acquired 40% of the outstanding common stock of Twin
County. The remaining shares were subject to an escrow agreement, pending
completion of the merger, and were required to be voted under the direction of
the Company. As of May 15, 1995, the Company also assumed management of Twin
County. As a result, the Company had control of Twin County and accordingly has
fully consolidated Twin County in the Company's financial statements since May
1995, the date of the original acquisition. The remaining outstanding common
stock of Twin County was acquired in September 1995. Goodwill relating to this
acquisition is being amortized over a period of approximately 10 years. In
January 1995, RCN International Holdings, Inc. (formerly C-TEC International,
Inc.), a wholly owned subsidiary of C-TEC, purchased a 40% equity position in
Megacable, the second largest cable television provider in Mexico. The Company
accounts for its investment by the equity method of accounting and is amortizing
the original excess cost over the underlying equity in the net assets on a
straight-line basis over 15 years.

     Year Ended December 31, 1997 Compared to Year Ended December 31, 1996

     For the year ended December 31, 1997, operating income before depreciation
and amortization and nonrecurring charge was ($7,670) as compared to $25,803 for
the year ended December 31, 1996. Sales increased 21.3% to $127,297 for the year
ended December 31, 1997 from $104,910 for the same period in 1996.

     Sales. Sales are primarily comprised of subscription fees for basic,
premium and pay per view cable television services; local telephone service fees
consisting primarily of monthly line charges, local toll and special features;
long distance telephone service fees based on minutes of traffic and tariffed
rates or contracted fees; and Internet access fees billed at contracted rates.
For the year ended December 31, 1997, sales were $127,297, an increase of
$22,387 due to higher Hybrid Fiber/Coaxial sales of $8,004 and higher Advanced
Fiber, Wireless Video and Other Operating sales of $14,343. The increase in
Hybrid Fiber/Coaxial sales principally results from higher basic service revenue
resulting from approximately 4,850 additional average monthly subscribers over
1996, the effects of a rate increase in the first quarter of 1997 and cash
incentives related to the launch of certain new channels. Advanced Fiber,
Wireless Video and Other Operating sales increased primarily due to the
acquisition of Freedom in August 1996 (the "Freedom Acquisition"), which
resulted in higher basic and premium video revenue. Additionally, higher voice
revenue of approximately $3,200 resulted from higher advanced fiber optic voice
connections and higher resold voice connections. The increase in Advanced Fiber,
Wireless Video and Other Operating sales also includes increases of
approximately $3,300 related to the long distance business.

     Costs and Expenses Excluding Depreciation and Amortization and Nonrecurring
Charges. Costs and expenses, excluding depreciation and amortization and
nonrecurring charges, are comprised of direct costs of providing services,
primarily cable programming and franchise costs, network access fees, video
transmission licensing fees, salaries and benefits, and customer service costs;
sales and marketing costs; and general and administrative expenses. For the year
ended December 31, 1997, costs and expenses, excluding depreciation,
amortization, and nonrecurring charges, were $134,967, an increase of $55,860 or
70.6% as compared to 1996. The increase is primarily attributable to higher
Advanced Fiber, Wireless Video and Other Operating costs and expenses, excluding
depreciation and amortization, of approximately $42,500, resulting principally
from the Freedom Acquisition in August 1996 and expansion of the business in the
Boston and New York City markets. The most significant increases occurred in
personnel and related costs, due to increased headcount primarily in operations,
marketing and customer service to support the expansion of the business,
origination and programming cost associated with an increase in video
connections, and advertising expenses of approximately $9,000 associated with a
high visibility campaign. The long distance business contributed approximately
$6,100 of the remaining increase in Advanced Fiber, Wireless Video and Other
Operating costs and expenses, excluding depreciation and amortization. Hybrid
Fiber/Coaxial costs and expenses, excluding depreciation and amortization,
increased approximately $8,300 primarily due to higher basic programming costs
resulting from higher rates, additional channels and subscriber increases.
Additionally, in connection with the Distribution (see Note 1 to the
Consolidated Financial Statements), C-TEC completed a comprehensive study of its
employee benefit plans in 1996. As a result of this study, effective December
31, 1996, in general, employees of RCN no longer accrued benefits under the
defined benefit pension plan, but became fully vested in their benefit accrued
through that date. C-TEC notified affected participants in December 1996. In
December 1996, C-TEC allocated pension plan assets of $6,984 to a separate plan
for employees who no longer accrue benefits after December 31, 1996 (the
"curtailed plan"). The underlying liabilities were also allocated. The
allocation of assets and liabilities resulted in a curtailment/settlement gain
attributable to Hybrid Fiber/Coaxial cable operations of approximately $1,500.
Such gain did not recur in 1997. The remaining increase in costs and expenses,
excluding depreciation and amortization, of approximately $5,000 is primarily
due to costs associated with the spin-off of the Company from C-TEC.

     Depreciation and Amortization. Depreciation and amortization is comprised
principally of depreciation relating to the Company's Hybrid Fiber/Coaxial
facilities, advanced fiber and wireless video network and amortization of
subscriber lists, building access rights and goodwill. Depreciation and
amortization increased $14,324, or 36.8% to $53,205 for the year ended December
31, 1997 as compared to $38,881 for 1996. The increase is principally due to the
additional depreciation and amortization resulting from the Freedom Acquisition
and depreciation related to the Company's advanced fiber optic networks in New
York City and Boston.

     In future periods, depreciation and amortization are expected to exceed
amounts recorded in 1997 due to depreciation with respect to the Company's
advanced fiber optic networks in New York City and Boston and due to
depreciation and amortization with respect to the Company's acquisitions in
February 1998 of Erols and Ultranet. See Note 19 to the Consolidated Financial
Statements.

     Nonrecurring Charges. Nonrecurring charges of $10,000 represent costs
incurred with respect to the termination of a marketing services agreement held
by Freedom.

     Interest Income. For the year ended December 31, 1997, interest income was
$22,824, a decrease of $2,778, or 10.9% primarily due to lower average cash
balances and lower average notes receivable with related parties. Average cash
balances decreased principally as a result of the Freedom Acquisition in August
1996 (as well as the acquisition in March 1997 of the remaining 19.9% ownership
interest in Freedom) and capital expenditures, partially offset by the proceeds
of the Company's high yield debt offering in October 1997. See Note 10 to the
Consolidated Financial Statements.

     Interest Expense. For the year ended December 31, 1997, interest expense
was $25,602, an increase of $9,556, or 59.6% primarily due to interest expense
on the Company's $225,000 of 10% Senior Notes and $601,045 aggregate principal
amount at maturity of 11 1/8% Senior Discount Notes placed in October 1997. See
Note 10 to the Consolidated Financial Statements. This was partially offset by
lower interest expense resulting from the required principal payment of $18,750
on 9.65% Senior Secured Notes in December 1996. Additionally, the Company paid
$922 to Kiewit Telecom in 1996 in connection with the Company's August 1996
acquisition of Kiewit Telecom's 80.1% interest in Freedom. This portion of the
consideration represents an amount to compensate Kiewit Telecom for forgone
interest on the amount which it had invested in Freedom.

     Income Tax. Benefit for income taxes increased $21,828 primarily due to the
increase of $65,020 in loss before taxes. For an analysis of the change in
income taxes, see the reconciliation of the effective income tax rate in Note 11
to the Consolidated Financial Statements.

     Minority Interest. Minority interest in the loss of consolidated entities
increased $5,956 primarily as a result of the minority share of the losses of
the BECO joint venture (see Note 7 to the Consolidated Financial Statements),
which began operations in June 1997. Additionally, the minority share of the
losses of Freedom from January 1 through March 21, at which time the Company
acquired the remaining 19.9% ownership interest, was $966.

     Equity in Loss of Unconsolidated Entities. The Company's equity in the
(loss) of unconsolidated entities was ($3,804) in 1997 and ($2,282) in 1996, and
is comprised principally of the Company's share of the operating results of
Megacable. In January 1995, the Company purchased a forty percent equity
position in Megacable, a Mexican cable television provider, for cash of $84,115.
The Company is exposed to foreign currency translation adjustments resulting
from translation into U.S. dollars of the financial statements of Megacable,
which through December 1996 utilized the peso as the local and functional
currency. Such adjustments have historically been included as a separate
component of shareholders' equity. Effective January 1, 1997, since the three
year cumulative rate of inflation at December 31, 1996 exceeded 100% , Mexico is
being treated for accounting purposes under Statement of Financial Accounting
Standards No. 52 -- "Foreign Currency Translation" as having a highly
inflationary economy. As a result, the financial statements of Megacable are
remeasured as if the functional currency were the U.S. dollar. The remeasurement
of the Mexican peso into U.S. dollars creates translation adjustments which are
included in net income. The Company is also exposed to foreign currency
transaction losses resulting from transactions of Megacable which are made in
currencies different from its own. The Company's proportionate share of
transaction gains (losses) are included in income as they occur. The Company
does not hedge its foreign currency exchange risk and it is not possible to
determine what effect future currency fluctuations will have on the Company's
operating results. Exchange gains (losses) of ($12), $247, and ($932) in 1997,
1996, and 1995, respectively, including translation losses in 1997, are included
in the respective statements of operations through the Company's proportionate
share of losses of Megacable.

     In 1997, Megacable had sales of $30,441, operating income before
depreciation and amortization of $10,504 and net income of $6,653. In 1996,
Megacable had sales of $23,225, operating income before depreciation and
amortization of $10,183 and net income of $10,226. Year end subscriber counts
were 211,627 at December 31, 1997 as compared to 178,664 at December 31, 1996.
In 1997 and 1996, the Company's share of the income of Megacable was $2,411 and
$4,090, respectively, which includes the exchange gains (losses) as discussed
above. The Company's investment in Megacable exceeded its underlying equity in
the net assets of Megacable when acquired by approximately $94,000, which
goodwill is being amortized on a straight-line basis over 15 years. In 1997 and
1996, amortization of the Company's excess purchase price over the net assets of
Megacable when acquired was $6,280 in each year.

     Extraordinary Charge. In September 1997, the Company prepaid Senior Secured
Notes with the proceeds of new credit facilities. See Note 10 to the
Consolidated Financial Statements. The early extinguishment of the 9.65% Senior
Secured Notes resulted in an extraordinary charge of $3,210, net of taxes.

     Year Ended December 31, 1996 Compared to Year Ended December 31, 1995

     For the year ended December 31, 1996, operating income before depreciation
and amortization was $25,803 as compared to $16,994 for the year ended December
31, 1995. Sales increased 14.0% to $104,910 for 1996 from $91,997 in 1995. The
improvement in operating income before depreciation and amortization of $8,809
was offset by higher depreciation and amortization of $16,545, as discussed
below, resulting in a net loss of ($5,989) for the year ended December 31, 1996
as compared to net income of $2,114 in 1995.

     Sales. For 1996, sales were $104,910, an increase of $12,913, or 14.0% due
to higher Hybrid Fiber/Coaxial sales partially offset by lower Advanced Fiber,
Wireless Video and Other Operating sales, principally long distance. Hybrid
Fiber/Coaxial sales increased $17,692, or 26.6%, primarily due to the
acquisition of the Pennsylvania cable system (formerly Twin County Trans Video,
Inc.) in May 1995, which resulted in $13,530 of the increase in Hybrid
Fiber/Coaxial sales in 1996. The Pennsylvania cable system serves approximately
74,000 subscribers in the Greater Lehigh Valley area of Pennsylvania. The 14.0%
increase in sales in 1996 was lower than the increase of 54.6% in 1995,
principally due to the consolidation of the Pennsylvania cable system for seven
months (from acquisition in May 1995). Since the Pennsylvania cable system was
consolidated for seven months in 1995, consolidation for a full year in 1996
reflects only an incremental five months revenue as compared to an incremental
seven months revenue in 1995. Additionally, long distance revenues decreased
approximately 30% from 1995 to 1996, principally as a result of termination of
AT&T Tariff 12 production in 1996, as compared to increases of 77% from 1994 to
1995, which resulted from the resale of AT&T Tariff 12 long distance services
and increases in long distance switched business and 800 services sales in 1995.
The remaining increase in Hybrid Fiber/Coaxial sales is due to higher basic
service revenues resulting from an increase in average subscribers of 4,995 or
5.3% and the full year impact, in 1996, of the 9.6% rate increase in April 1995
and the impact of 5.9% rate increase in February 1996. These increases were
partially offset by lower Advanced Fiber, Wireless Video and Other Operating
sales of $4,760 primarily resulting from the termination in the second quarter
of 1995 of an agreement for the resale of AT&T Tariff 12 long distance services
to another long distance reseller. Included in Advanced Fiber, Wireless Video
and Other Operating sales for 1996 were Wireless Video sales of $3,532, compared
to zero for 1995 reflecting the Freedom Acquisition.

     Cost and Expenses, Excluding Depreciation and Amortization. In 1996, costs
and expenses, excluding depreciation and amortization, were $79,107, an increase
of $4,104 or 5.5% as compared to 1995. Hybrid Fiber/Coaxial programming expense
increased $3,930 due to license fee increases, channel additions, and subscriber
growth, primarily due to the acquisition of the Pennsylvania cable system.
Additionally, Hybrid Fiber/Coaxial salaries and benefits expense increased
$1,862 primarily due to the acquisition of the Pennsylvania cable system.
Corporate costs and expenses, excluding depreciation and amortization, decreased
$487. This decrease is primarily due to the corporate allocable share of the
gain on the partial curtailment and settlement of C-TEC's defined benefit
pension plan of $992 (see Note 13 to the Consolidated Financial Statements)
partially offset by the Company's allocable portion of costs associated with the
investigation of the feasibility of various restructuring alternatives to
enhance shareholder value. Advanced Fiber, Wireless Video and Other Operating
costs and expenses, excluding depreciation and amortization, decreased $1,465
primarily due to lower expenses associated with the 97% reduction in AT&T Tariff
12 long distance revenues partially offset by an increase of $2,320 representing
costs associated with the development of the Company's advanced fiber optic
networks in New York City and Boston and Wireless Video costs and expenses of
$8,303 in 1996 compared to zero in 1995 reflecting the Freedom Acquisition.

     Depreciation and Amortization. For 1996, depreciation and amortization
expense was $38,881, an increase of $16,545 or 74.1% as compared to 1995
primarily due to purchase accounting effects of the acquisition of Pennsylvania
cable system in May 1995 and the Freedom acquisition on August 30, 1996. See
Note 4 to the Consolidated Financial Statements. In addition, the Company
incurred $3,756 in depreciation related to the Company's advanced fiber optic
networks in New York City and Boston.

     Interest Income. For the year ended December 31, 1996, interest income was
$25,602, a decrease of $3,399, or 11.7% due primarily to a reduction in average
cash balances in 1996 as compared to 1995 and a decrease in the average yield on
invested cash, partially offset by interest income of $2,222 accrued on a
$13,088 note receivable acquired from Mazon Corporativo S.A. de C.V. in January
1996. Average cash balances decreased in 1996 primarily due to cash used in the
Freedom acquisition and the purchase of the loan receivable from Mazon
Corporativo S. A. de C.V. Additionally, lower balances on notes
receivable-affiliates contributed to the decrease.

     Interest Expense. Interest expense for 1996 was $16,046, a decrease of
$471, or 2.9% in 1996 as compared to 1995. This decrease is due to lower average
rates on outstanding debt and includes approximately $922 paid to Kiewit
Telecom, the Company's controlling shareholder, in connection with the Freedom
acquisition. This portion of the consideration represents an amount to
compensate Kiewit Telecom for forgone interest on the amount invested in
Freedom.

     Income Taxes. The Company's effective income tax rate was (19.5%) in 1996
and 34.6% in 1995. For an analysis of the change in income taxes, see the
reconciliation of the effective income tax rate in Note 11 to the Consolidated
Financial Statements.

     Minority Interest. As a result of the Freedom Acquisition, Freedom's
financial results are consolidated with the Company since August 30, 1996, the
date of acquisition. This resulted in minority interest in the loss of Freedom
of $1,546 for 1996. Additionally, the 20% minority interest in the income of
HomeLink Limited Partnership, a Hybrid Fiber/Coaxial subsidiary, was ($206) in
1996 as compared to ($144) in 1995.

     Equity in Loss of Unconsolidated Entities. In 1996, Megacable had sales of
$23,225, operating income before depreciation and amortization of $10,183 and
net income of $10,226. In 1995, Megacable had sales of $20,841, operating income
before depreciation and amortization of $8,154 and net income of $5,802. Year
end subscriber counts were 178,664 at December 31, 1996 as compared to 177,317
at December 31, 1995. In 1996 and 1995, the Company's share of the income of
Megacable was $4,090 and $2,696, respectively, which includes foreign currency
transaction losses as noted in the 1997 discussion. In 1996 and 1995,
amortization of the Company's excess purchase price over the net assets of
Megacable when acquired was $6,280 and $5,757, respectively.

Liquidity and Capital Resources

     The Company expects that it will require a substantial amount of capital to
fund the network development and operations in the Boston to Washington, D.C.
corridor, including funding the development of its advanced fiber optic
networks, upgrading its Hybrid Fiber/Coaxial plant, funding operating losses and
debt service requirements. The Company currently estimates that its capital
requirements for the period from January 1, 1998 through 1999 will be
approximately $785,000, which includes capital expenditures (including
connection costs which will only be incurred as the Company obtains
revenue-generating customer connections) of approximately $300,000 in 1998 and
approximately $485,000 in 1999. These capital expenditures will be used
principally to fund the buildout of the Company's fiber optic network in high
density areas in the Boston, New York and Washington, D.C. markets and to
upgrade its Hybrid Fiber/Coaxial cable systems. To build out these areas on an
efficient basis, the Company undertakes a subscriber-driven capital expenditure
strategy whereby it (i) closely monitors development of its subscriber base in
order to tailor network development in each target market, and (ii) seeks to
establish a customer base in advance of or concurrently with its network
deployment. For example, the Company offers resale telephone services on an
interim basis to customers located near its advanced fiber optic networks.
Depending upon factors such as subscriber density, proximity to the advanced
fiber optic network and development costs and the degree of success achieved in
its initial markets, the Company will determine whether extending its advanced
fiber optic network to additional high density target markets can be achieved on
an attractive economic basis. In addition to its own capital requirements, the
Company's joint venture partners are each expected to contribute approximately
$150,000 in capital to the joint ventures in connection with development of the
Boston and Washington, D.C. markets through 2000.

     In October 1997, the Company raised $575,000 in gross proceeds from an
offering of two tranches of debt securities. The offering was comprised of
$225,000 principal amount of 10% Senior Notes and $601,000 principal amount at
maturity of 11 1/8% Senior Discount Notes, both due in 2007. The proceeds
include $61,045 of restricted cash to be used to fund the Escrow Account to pay
interest on the 10% Senior Notes for three years. In February 1998, the Company
raised $350,587 in gross proceeds from an offering of $567,000 principal amount
at maturity of 9.8% Senior Discount Notes, due in 2008. The Company expects to
have sufficient liquidity to meet its capital requirements through mid-2000. The
Company will continue to require additional capital for planned increases in
network coverage and other capital expenditures, working capital, debt service
requirements, and anticipated further operating losses. The actual timing and
amount of capital required to roll out the Company's network and to fund
operating losses may vary materially from the Company's estimates and additional
funds will be required in the event of significant departures from the current
business plan, unforeseen delays, cost overruns, engineering design changes and
other technological risks or other unanticipated expenses. Due to its subscriber
driven investment strategy, should the Company encounter a successful rollout in
its initial markets, the Company may accelerate the expansion and extend the
reach of its network. Conversely, should the Company be less successful than
anticipated, the operating losses associated with the installed network may be
higher than anticipated. The Company presently intends to judge the success of
its initial rollout in deciding whether to undertake additional capital
expenditures to rollout the network to additional areas. Since the Company
anticipates that, if it is successful, it will continue to extend its network
coverage into additional areas within the Boston-Washington, D.C. corridor, it
expects to continue to experience losses and negative cash flow on an aggregate
basis for an extended period of time.

     The Company's current joint venture agreements reduce the amount of
expenditures required by RCN to develop the network due both to access to the
joint venture partners' existing facilities and to the anticipated joint venture
partners' equity contributions. However, the joint venture arrangements will
also reduce the potential cash flows to be realized from operation of the
networks in the markets in which the joint ventures operate and restrict the
Company's access to cash flow generated by the joint ventures (which will be
paid in the form of dividends). The Company may enter into additional joint
ventures in the future as the Company begins to develop new markets.

     Sources of funding for the Company's further financing requirements may
include vendor financing, public offering or private placements of equity and/or
debt securities, and bank loans. There can be no assurance that additional
financing will be available to the Company or, if available, that it can be
obtained on a timely basis and on acceptable terms. Failure to obtain such
financing could result in the delay or curtailment of the Company's development
and expansion plans and expenditures. Any of these events could impair the
Company's ability to meet its debt service requirements and could have a
material adverse effect on its business.

     RCN Cable and certain of its subsidiaries have in place secured credit
facilitates comprised of a five-year revolving credit facility in the amount of
$25,000 (the "Revolving Credit Facility") and an eight- year term credit
facility in the amount of $100,000 (the "Term Credit Facility"), both of which
facilities are governed by a single credit agreement dated as of July 1, 1997
(the "Credit Agreement"). As of December 31,1997, $100,000 of the Term Credit
Facility was outstanding. The term loan must be repaid over six years in
quarterly installments, at the end of September, December, March and June of
each year from September 30, 1999 through June 30, 2005. As of December 31,
1997, $3,000 principal was outstanding under the Revolving Credit Facility.
Revolving loans may be repaid and reborrowed from time to time.

     The Company has indebtedness that is substantial in relation to its
shareholders' equity and cash flow. At December 31, 1997, after giving effect to
the 1998 Notes Offering, the Company had an aggregate of approximately
$1,036,000 of indebtedness outstanding, and the ability to borrow up to an
additional $22,000 under the Credit Agreement. As a result of the substantial
indebtedness of the Company, the Company's fixed charges are expected to exceed
its earnings for the foreseeable future. In addition, the Company will require
substantial additional indebtedness particularly in connection with the buildout
of the Company's networks and the introduction of its telecommunications
services to new markets. The leveraged nature of the Company could limit its
ability to effect future financing or may otherwise restrict the Company's
business activities.

     The extent of the Company's leverage may have the following consequences:
(i) limit the ability of the Company to obtain necessary financing in the future
for working capital, capital expenditures, debt service requirements or other
purposes; (ii) require that a substantial portion of the Company's cash flows
from operations be dedicated to the payment of principal and interest on its
indebtedness and therefore not be available for other purposes; (iii) limit the
Company's flexibility in planning for, or reacting to, changes in its business;
(iv) place the Company at a competitive disadvantage as compared with less
leveraged competitors; and (v) render the Company more vulnerable in the event
of a downturn in its business.

     For the year ended December 31, 1997, the Company's net cash provided by
operating activities was $1,661, comprised primarily of a net loss of ($52,391)
adjusted by non-cash depreciation and amortization of $53,205, other non-cash
items totaling ($611) , working capital changes of $377 and changes in other
deferred expenses of $1,081. Net cash used in investing activities of $475,860
consisted primarily of purchases of short-term investments of $445,137,
additions to property, plant and equipment of $79,042 and acquisitions of
$30,490 (primarily acquisition of the minority interest of Freedom) partially
offset by sales and maturities of short-term investments of $76,923. Net cash
provided by financing activities of $635,266 consisted primarily of issuance of
long-term debt of $688,000, change in affiliate notes of $97,624 and transfers
from C-TEC of $89,324 partially offset by redemption of long-term debt of
$141,250, transfers to C-TEC of $23,474, payments made for debt financing costs
of $19,743 and an increase related to cash restricted for debt service of
$61,250.

     For the year ended December 31, 1996, the Company's net cash provided by
operating activities was $23,831 comprised primarily of a net loss of $5,989
adjusted by non-cash depreciation and amortization of $38,881 and other non-cash
items totaling ($7,184). Net cash used in investing activities of $9,377
consisted primarily of additions to property, plant and equipment of $40,369,
the purchase of a loan receivable of $13,088 and acquisitions of $30,090
(primarily the Freedom Acquisition), partially offset by net sales and
maturities of short-term investments of $73,995. Net cash provided by financing
activities of $9,391 included the issuance of long-term debt of $19,000 and
change in affiliate notes of $32,802 partially offset by the redemption of
long-term debt of $44,750.

     Impact of the Year 2000 Issue

     The Company has certain financial, administrative and operational systems
which are subject to Year 2000 exposures. The Company has performed a study to
identify those specific systems which require remediation and developed a plan
to correct such situations in a timely fashion. The Company's plan is proceeding
on target. The plan includes ensuring that those systems for which the Company
is dependent on external vendors, such as certain billing systems, will be Year
2000 compliant by the end of 1999 based on the status of external vendors'
remediation efforts. For those internal systems that require corrective action,
the Company has contracted with its information systems services provider to
rewrite the relevant programming code. Finally, the Company is well along on a
conversion of its suite of financial systems to a state-of-the-art Oracle
system. Such system is expected to ensure Year 2000 compliance in financial
applications, enable the Company to process and report its financial
transactions more efficiently and provide a greater level of detailed
information to facilitate management's analysis which is critical to its
business decisions.

     The Company is employing a team approach across its MIS, financial and
operational groups in addressing the above issues, as well as utilizing the
assistance of external consultants in the case of the Oracle implementation.
Such team approach facilitates a consistent progress along plans without
disruption of other areas of the business.

     There is no assurance that the Company's plans will continue to progress as
intended. The Company estimates that its cost of Year 2000 remediation will not
be material.

     The tender to the Company of Old Notes by a holder thereof as set forth
below and the acceptance thereof by the Company will constitute a binding
agreement between the tendering holder and the Company upon the terms and
subject to the conditions set forth in this Prospectus and in the accompanying
Letter of Transmittal. Except as set forth below, a holder who wishes to tender
Old Notes for exchange pursuant to the Exchange Offer must transmit a properly
completed and duly executed Letter of Transmittal, including all other documents
required by such Letter of Transmittal, to The Chase Manhattan Bank (the
"Exchange Agent") at one of the addresses set forth below under "Exchange Agent"
on or prior to the Expiration Date. In addition, (i) a timely confirmation of a
book-entry transfer (a "Book-Entry Confirmation") of such Old Notes, if such
procedure is available, into the Exchange Agent's account at The Depository
Trust Company (the "Book-Entry Transfer Facility") pursuant to the procedure for
book-entry transfer described below, must be received by the Exchange Agent
prior to the Expiration Date, (ii) certificates for such Old Notes must be
received by the Exchange Agent along with the Letter of Transmittal or (iii) the
holder must comply with the guaranteed delivery procedures described below. THE
METHOD OF DELIVERY OF OLD NOTES, LETTERS OF TRANSMITTAL AND ALL OTHER REQUIRED
DOCUMENTS IS AT THE ELECTION AND RISK OF THE HOLDERS. IF SUCH DELIVERY IS BY
MAIL, IT IS RECOMMENDED THAT REGISTERED MAIL, PROPERLY INSURED, WITH RETURN
RECEIPT REQUESTED, BE USED. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO
ASSURE TIMELY DELIVERY. NO LETTERS OF TRANSMITTAL OR OLD NOTES SHOULD BE SENT TO
THE COMPANY.

     Signatures on a Letter of Transmittal or a notice of withdrawal, as the
case may be, must be guaranteed unless the Old Notes surrendered for exchange
pursuant thereto are tendered (i) by a registered holder of the Old Notes who
has not completed the box entitled "Special Issuance Instructions" or "Special
Delivery Instructions" on the Letter of Transmittal or (ii) for the account of
an Eligible Institution (as defined below). In the event that signatures on a
Letter of Transmittal or a notice of withdrawal, as the case may be, are
required to be guaranteed, such guarantees must be by a firm which is a member
of a registered national securities exchange or a member of the National
Association of Securities Dealers, Inc. or by a commercial bank or trust company
having an office or correspondent in the United States (collectively, "Eligible
Institutions"). If Old Notes are registered in the name of a person other than
the person signing the Letter of Transmittal, the Old Notes surrendered for
exchange must be endorsed by, or be accompanied by a written instrument or
instruments of transfer or exchange, in satisfactory form as determined by the
Company in its sole discretion, duly executed by the registered holder with the
signature thereon guaranteed by an Eligible Institution.

     All questions as to the validity, form, eligibility (including time of
receipt) and acceptance of Old Notes tendered for exchange will be determined by
the Company in its sole discretion, which determination shall be final and
binding. The Company reserves the absolute right to reject any and all tenders
of any particular Old Notes not properly tendered or to not accept any
particular Old Notes which acceptance might, in the judgment of the Company or
its counsel, be unlawful. The Company also reserves the absolute right in its
sole discretion to waive any defects or irregularities or conditions of the
Exchange Offer as to any particular Old Notes either before or after the
Expiration Date (including the right to waive the ineligibility of any holder
who seeks to tender Old Notes in the Exchange Offer). The interpretation of the
terms and conditions of the Exchange Offer as to any particular Old Notes either
before or after the Expiration Date (including the Letter of Transmittal and the
instructions thereto) by the Company shall be final and binding on all parties.
Unless waived, any defects or irregularities in connection with the tenders of
Old Notes for exchange must be cured within such reasonable period of time as
the Company shall determine. Neither the Company, the Exchange Agent nor any
other person shall be under any duty to give notification of any defect or
irregularity with respect to any tender of Old Notes for exchange, nor shall any
of them incur any liability for failure to give such notification.

     If the Letter of Transmittal is signed by a person or persons other than
the registered holder or holders of Old Notes, such Old Notes must be endorsed
or accompanied by appropriate powers of attorney, in either case signed exactly
as the name or names of the registered holder or holders that appear on the Old
Notes.

     If the Letter of Transmittal or any Old Notes or powers of attorney are
signed by trustees, executors, administrators, guardians, attorneys-in-fact,
officers of corporations or others acting in a fiduciary or representative
capacity, such person should so indicate when signing and, unless waived by the
Company, proper evidence satisfactory to the Company of its authority to so act
must be submitted.

     By tendering, each holder will represent to the Company that, among other
things, (i) the New Notes acquired pursuant to the Exchange Offer are being
acquired in the ordinary course of business of the person receiving such New
Notes, whether or not such person is the holder, (ii) neither the holder nor any
such other person has an arrangement or understanding with any person to
participate in the distribution of such New Notes, (iii) if the holder is not a
broker-dealer, or is a broker-dealer but will not receive New Notes for its own
account in exchange for Old Notes, neither the holder nor any such other person
is engaged in or intends to participate in the distribution of such New Notes
and (iv) neither the holder nor any such other person is an "affiliate", as
defined under Rule 405 of the Securities Act, of the Company. If the exchange
offeree is a broker-dealer holding Old Notes acquired for its own account as a
result of market-making activities or other trading activities, it will be
required to acknowledge that it will deliver a prospectus in connection with any
resale of New Notes received in exchange for such Old Notes.

Acceptance of Old Notes for Exchange; Delivery of New Notes

     Upon satisfaction or waiver of all of the conditions to the Exchange Offer,
the Company will accept, promptly after the Expiration Date, all Old Notes
properly tendered and will issue the New Notes promptly after acceptance of the
Old Notes. See "--Certain Conditions to the Exchange Offer" below. For purposes
of the Exchange Offer, the Company shall be deemed to have accepted properly
tendered Old Notes for exchange when, as and if the Company has given oral or
written notice thereof to the Exchange Agent.

     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 certificates for such Old Notes or a timely Book-Entry
Confirmation of such Old Notes into the Exchange Agent's account at the
Book-Entry Transfer Facility pursuant to the book-entry transfer procedures
described below, a properly completed and duly executed Letter of Transmittal
and all other required documents. If any tendered Old Notes are not accepted for
any reason set forth in the terms and conditions of the Exchange Offer or if
certificates representing Old Notes are submitted for a greater principal amount
than the holder desires to exchange, such unaccepted or non-exchanged Old Notes
will be returned without expense to the tendering holder thereof (or, in the
case of Old Notes tendered by book-entry transfer into the Exchange Agent's
account at the Book-Entry Transfer Facility pursuant to the book-entry transfer
procedures described below, such non-exchanged Old Notes will be credited to an
account maintained with such Book-Entry Transfer Facility) as promptly as
practicable after the expiration or termination of the Exchange Offer.

Interest on the New Notes

     The Notes (including the New Notes) were issued at a substantial discount
from their principal amount. Commencing February 15, 2003, cash interest on the
Notes will accrue at the rate of 9.80% per annum and will be payable in cash
semi-annually on each February 15 and August 15, commencing on August 15, 2003.
Prior to August 15, 2003, there will be no periodic payment of interest. No
interest will have accrued on the Old Discount Notes on the date of the exchange
for the New Notes and therefore no interest will be paid thereon to the holders.

Book-Entry Transfer

     The Exchange Agent will make a request to establish an account with respect
to the Old Notes at the Book-Entry Transfer Facility for purposes of the
Exchange Offer promptly after the date of this Prospectus. Any financial
institution that is a participant in the Book-Entry Transfer Facility's systems
may make book-entry delivery of Notes by causing the Book-Entry Transfer
Facility to transfer such Notes into the Exchange Agent's account in accordance
with the Book-Entry Transfer Facility's Automated Tender Offer Program ("ATOP")
procedures for transfer. However, the exchange for the Notes so tendered will
only be made after timely confirmation of such book-entry transfer of Notes into
the Exchange Agent's account, and timely receipt by the Exchange Agent of an
Agent's Message (as such term is defined in the next sentence) and any other
documents required by the Letter of Transmittal. The term "Agent's Message"
means a message, transmitted by the Book-Entry Transfer Facility and received by
the Exchange Agent and forming a part of a Book-Entry Confirmation, which states
that the Book-Entry Transfer Facility has received an express acknowledgment
from a participant tendering Notes that are the subject of such Book-Entry
Confirmation that such participant has received and agrees to be bound by the
terms of the Letter of Transmittal, and that the Company may enforce such
agreement against such participant.

Guaranteed Delivery Procedures

     If a registered holder of the Old Notes desires to tender such Old Notes
and the Old Notes are not immediately available, or time will not permit such
holder's Old Notes or other required documents to reach the Exchange Agent
before the Expiration Date, or the procedure for book-entry transfer cannot be
completed on a timely basis, a tender may be effected if (i) the tender is made
through an Eligible Institution, (ii) prior to the Expiration Date, the Exchange
Agent receives from such Eligible Institution a properly completed and duly
executed Letter of Transmittal (or a facsimile thereof) and Notice of Guaranteed
Delivery, substantially in the form provided by the Company (by telegram, telex,
facsimile transmission, mail or hand delivery), setting forth the name and
address of the holder of Old Notes and the amount of Old Notes tendered, stating
that the tender is being made thereby and guaranteeing that within five New York
Stock Exchange ("NYSE") trading days after the date of execution of the Notice
of Guaranteed Delivery, the certificates of all physically tendered Old Notes,
in proper form for transfer, or a Book-Entry Confirmation, as the case may be,
and any other documents required by the Letter of Transmittal will be deposited
by the Eligible Institution with the Exchange Agent, and (iii) the certificates
for all physically tendered Old Notes, in proper form for transfer, or a
Book-Entry Confirmation, as the case may be, and all other documents required by
the Letter of Transmittal, are received by the Exchange Agent within five NYSE
trading days after the date of execution of the Notice of Guaranteed Delivery.

Withdrawal Rights

     Tenders of Old Notes may be withdrawn at any time prior to the Expiration
Date.

     For a withdrawal to be effective, a written notice of withdrawal must be
received by the Exchange Agent at one of the addresses set forth below under
"Exchange Agent." Any such notice of withdrawal must specify the name of the
person having tendered the Old Notes to be withdrawn, identify the Old Notes to
be withdrawn (including the principal amount of such Old Notes), and (where
certificates for Old Notes have been transmitted) specify the name in which such
Old Notes are registered, if different from that of the withdrawing holder. If
certificates for Old Notes have been delivered or otherwise identified to the
Exchange Agent, then, prior to the release of such certificates, the withdrawing
holder must also submit the serial numbers of the particular certificates to be
withdrawn and a signed notice of withdrawal with signatures guaranteed by an
Eligible Institution unless such holder is an Eligible Institution. If Old Notes
have been tendered pursuant to the procedure for book-entry transfer described
above, any note of withdrawal must specify the name and number of the account at
the Book-Entry Transfer Facility to be credited with the withdrawn Old Notes and
otherwise comply with the procedures of such facility. All questions as to the
validity, form and eligibility (including time of receipt) of such notices will
be determined by the Company, whose determination shall be final and binding on
all parties. Any Old Notes so withdrawn will be deemed not to have been validly
tendered for exchange for purposes of the Exchange Offer. Any Old Notes which
have been tendered for exchange but which are not exchanged for any reason will
be returned to the holder thereof without cost to such holder (or, in the case
of Old Notes tendered by book-entry transfer into the Exchange Agent's account
at the Book-Entry Transfer Facility pursuant to the book-entry transfer
procedures described above, such Old Notes will be credited to an account
maintained with such Book-Entry Transfer Facility for the Old Notes) 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 under "--Procedures for Tendering Old Notes" above at any
time on or prior to the Expiration Date.

Certain Conditions to the Exchange Offer

     Notwithstanding any other provisions of the Exchange Offer, the Company
shall not be required to accept for exchange, or to issue New Notes in exchange
for, any Old Notes and may terminate or amend the Exchange Offer, if at any time
before the acceptance of such Old Notes for exchange or the exchange of the New
Notes for such Old Notes, such acceptance or issuance would violate applicable
law or any interpretation of the staff of the Commission.

     The foregoing condition is for the sole benefit of the Company and may be
asserted by the Company regardless of the circumstances giving rise to such
condition or may be waived by the Company in whole or in part at any time and
from time to time in its sole discretion. The failure by the Company at any time
to exercise 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.

     In addition, the Company will not accept for exchange any Old Notes
tendered, and no New Notes will be issued in exchange for any such Old Notes, if
at such time any stop order shall be threatened or in effect with respect to the
Registration Statement of which this Prospectus constitutes a part or the
qualification of the Indenture under the Trust Indenture Act of 1939, as amended
(the "TIA").

Fees and Expenses

     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 the Company and its affiliates. No additional compensation
will be paid to any such officers and employees who engage in soliciting
tenders. The Company will not make any payment to brokers, dealers, or others
soliciting acceptances of the Exchange Offer. The Company, 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.

     The estimated cash expenses to be incurred in connection with the Exchange
Offer will be paid by the Company and are estimated in the aggregate to be
$250,000.

Transfer Taxes

     Holders who tender their Old Notes for exchange will not be obligated to
pay any transfer taxes in connection therewith, except that holders who instruct
the Company to register New Notes in the name of, or request that Old Notes not
tendered or not accepted in the Exchange Offer be returned to, a person other
than the registered tendering holder will be responsible for the payment of any
applicable transfer tax thereon.

Consequences of Failure to Exchange

     Holders of Old Notes who do not exchange their Old Notes for New Notes
pursuant to the Exchange Offer will continue to be subject to the restrictions
on transfer of such Old Notes as set forth in the legend thereon. In general,
the Old Notes may not be offered or sold, unless registered under the Securities
Act, except pursuant to an exemption from, or in a transaction not subject to,
the Securities Act and applicable state securities laws. The Company does not
intend to register the Old Notes under the Securities Act. The Company believes
that, based upon interpretations contained in letters issued to third parties by
the staff of the Commission, New Notes issued pursuant to the Exchange Offer in
exchange for Old Notes may be offered for resale, resold or otherwise
transferred by each holder thereof (other than a broker-dealer, as set forth
below, and any such holder which is an "affiliate" of the Company 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 and such holder has no arrangement or understanding with any person to
participate in the distribution of such 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, such 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
such New Notes. See "Plan of Distribution." In addition, to comply with the
securities laws of certain jurisdictions, if applicable, the New Notes may not
be offered or sold unless they have been registered or qualified for sale in
such jurisdiction or an exemption from registration or qualification is
available and is complied with. The Company does not currently intend to take
any action to register or qualify the New Notes for resale in any such
jurisdictions.


                                    BUSINESS

Overview

     RCN is developing advanced fiber optic networks to provide a wide range of
telecommunications services including local and long distance telephone, video
programming and data services (including high speed Internet access), primarily
to residential customers in selected markets in the Boston to Washington, D.C.
corridor. The region, one of the most densely populated in the United States,
represents approximately 4% of the geography of the U.S., but accounts for over
26% of the telecommunications market based upon the number of telephone access
lines. The Company believes that of the estimated 22 million homes in the Boston
to Washington, D.C. corridor, approximately 9 million homes are located in
high-density urban and suburban residential areas that will support development
of an advanced fiber optic network on an attractive economic basis. RCN believes
that its capability to deliver multiple services (telephone, video programming
and Internet access) to any given customer on its networks will provide it with
competitive advantages over other competitors. RCN's strategy is to become the
leading single-source provider of voice, video and data services to residential
customers in each of its markets by offering individual or bundled service
options, superior customer service and competitive prices.

     RCN's initial advanced fiber optic networks have been established in New
York City and, through a joint venture with BECO, in Boston and surrounding
communities. RCN has also entered into a joint venture named Starpower with
Pepco Communications, an indirect wholly owned subsidiary of PEPCO, to develop
an advanced fiber network in the Washington, D.C. area. On February 20, 1998,
RCN acquired Washington, D.C.'s largest ISP, Erols, and on February 27, 1998,
RCN acquired Boston's largest ISP, Ultranet. RCN also benefits from a strategic
relationship with MFS/WorldCom in New York City and Boston and from its
interconnection and resale agreements with incumbent telephone service providers
including Bell Atlantic. RCN believes that these joint ventures and
relationships provide it with a number of important advantages including access
to rights of way and use of existing fiber optic facilities, the ability to
enter its target markets quickly and efficiently and a reduction in the up-front
capital investment required to develop its networks. In addition, the Company's
joint venture partners provide access to additional assets, equity capital and
established customer bases. The Company also benefits from its relationship with
its largest shareholder, PKS, the founder of MFS Communications Company, Inc.,
and from the experience gained by certain of the Company's key employees who
participated in the development of MFS Communications Company, Inc.

     As of December 31, 1997, the Company had approximately 267,600 connections
which were delivered through a variety of owned and leased facilities including
hybrid fiber/coaxial cable systems, a wireless video system and advanced fiber
optic networks. In addition, the Company gained approximately 325,000 Internet
service customers as a result of the recent completion of the acquisitions of
Ultranet and Erols. Without giving effect to such acquisitions, RCN had pro
forma revenues and EBITDA before nonrecurring charges of $127.3 million and
$(7.7) million, respectively, for the year ended December 31, 1997 and $110.1
million and $23.5 million, respectively, for the year ended December 31, 1996.
The Company is deploying advanced fiber optic networks specifically designed to
provide high speed, high capacity telecommunications services for all new
network facilities. RCN also intends to upgrade certain of its hybrid
fiber/coaxial cable systems to enable them to provide the same range of voice,
video and data services, including bundled service options. See "--The Delivery
Platforms." Since it formally commenced operation of its advanced fiber optic
networks in New York City and Boston in September 1996, RCN has built or
acquired, through its joint venture with BECO and long term lease arrangements,
approximately 400 route miles of fiber optic cable and added approximately
15,100 customer connections to its advanced fiber optic networks. In addition,
during the same period the Company added approximately 29,700 wireless video,
resold telephone and other connections, the majority of which represent
customers that RCN expects to migrate to its advanced fiber optic networks. At
December 31, 1997, RCN had approximately 82,700 total connections attributable
to customers in the New York City and Boston markets (of which approximately
42,600 were wireless video service and other connections and approximately
24,900 were resold telephone connections) and had approximately 184,900 were
connections attributable to its hybrid fiber/coaxial cable systems in the states
of New York (outside New York City), New Jersey and Pennsylvania, all within 75
miles of New York City. Because it delivers multiple services, RCN reports the
total number of its various service connections (for local telephone, video
programming and Internet access) rather than the number of customers. See "--RCN
Services--Connections."

     RCN's extensive operating experience in both the telephone and video
industries and in the design and development of telecommunications facilities
provides it with expertise in systems operation and development, an established
infrastructure for customer service and billing for both voice and video
services and established relationships with providers of equipment and video
programming. In addition, the Company's management team and board of directors
benefit from experience gained in connection with the management of C-TEC, which
prior to September 30, 1997 owned and operated RCN. See "Description of the
Distribution and Related Agreements--Background." C-TEC has 100 years of
experience in the telephone business and nearly 25 years of experience in the
cable television business. Both C-TEC and certain members of management also
have extensive experience in the design and development of advanced
telecommunications facilities.

     RCN seeks to exploit competitive opportunities which have resulted from
widespread changes in the U.S. telecommunications industry. Industry sources
estimate that annual revenues generated by the U.S. telecommunications industry
in 1996 were approximately $210 billion (comprised of $183 billion in
telecommunications revenues and $27 billion in cable television revenues).
Approximately 50% of such revenue is estimated to be attributable to residential
users. RCN believes that density is a critical factor in the effective economic
deployment of its networks, and that the Boston to Washington, D.C. corridor is
a particularly attractive market for developing advanced fiber optic facilities
due to population density, favorable demographics and the aging infrastructure
of the incumbent service providers' network facilities in this region. The
Company applies a subscriber-driven investment strategy focusing on subscriber
density, proximity to the Company's advanced fiber optic networks and network
development costs, in order to determine if the number of potential connections
in a target area will permit network development on an attractive economic
basis.

Business Strategy

     The Company believes that the opportunity to effectively deploy advanced
fiber optic networks and to compete with incumbent telephone and cable
television service providers results from several key factors, including the
broad deregulation of the telecommunications industry pursuant to the
Telecommunications Act of 1996, the need for more advanced, higher capacity
networks to meet growing consumer demands for new communications products and
services and the superior technology of the Company's networks. In order to
achieve its goal of becoming the leading provider of telecommunications, video
and data services to residential customers in its target markets, RCN is
pursuing the following key strategies:

     Developing Advanced Fiber Optic Networks. RCN's advanced fiber optic
networks are specifically designed to provide a single source for high speed,
high capacity voice, video programming and data services. RCN believes that its
high capacity advanced fiber optic networks provide RCN with certain competitive
advantages such as increased capacity (including the ability to offer bundled
voice, video and data services) and generally superior signal quality and
network reliability relative to the typical networks of the incumbent service
providers. By using advanced fiber optic networks capable of delivering multiple
services, RCN is able to address a larger number of potential subscriber
connections in its target markets than incumbent service providers which
typically provide only single or limited services.

     Focusing on Residential Customers in High-Density Markets. RCN seeks to be
the first operator of an advanced fiber optic network providing voice, video and
data services to residential customers in each of its target markets. RCN
believes that it is unique in its markets in offering a wide range of bundled
voice, video and data services to customers in residential areas and in striving
to connect residential customers directly to its advanced fiber optic networks.
RCN also believes that residential customers will be attracted to lower prices,
broader service offerings, enhanced levels of customer care and consumer choice.
Although the Company's primary focus is on residential customers, RCN also
serves certain commercial accounts which are located on or in close proximity to
its networks.

     Implementing Subscriber-Driven Investment Strategy. RCN attempts to
efficiently deploy its capital by tying facility development to the procurement
of customer connections. In order to promote its presence in its markets and to
develop a subscriber base for its advanced fiber optic networks, the Company may
provide telephone services to customers located near its advanced fiber networks
by first reselling services, and then by establishing leased facilities (such as
unbundled local loops), in advance of constructing or extending its networks.
RCN also provides wireless video services to approximately 38,000 customers in
New York City with a view to extending the advanced fiber optic network to
service many of these existing customers. In addition, RCN intends to extend its
network to cover the primary areas currently served by Erols and Ultranet.

     Utilizing Strategic Alliances and Existing Facilities to Speed and Reduce
Cost of Entry. By utilizing strategic alliances, RCN is able to enter the market
quickly and efficiently and to reduce the up-front capital investment required
to develop its networks. Through alliances with companies such as BECO, Pepco
Communications and MFS/WorldCom, which provide or are expected to provide RCN
with extensive fiber optic networks or other assets, by utilizing certain
components of its own existing cable television infrastructure, and through the
strategic acquisitions of Ultranet and Erols, RCN has been able to expedite and
reduce the cost of market entry and business development and has created the
opportunity to leverage existing customer relationships.

     Offering Bundled Voice, Video and Data Services. RCN believes that, as a
full service voice, video and data programming provider, it will be able to
offer a single-source package of voice, video and data services, individually or
on a bundled basis, which is not yet generally available from any incumbent
telephone, cable or other service provider. In addition, services provided over
RCN's advanced fiber optic networks are generally priced at competitive rates as
compared to the incumbent service providers.

     Providing Superior Customer Service. RCN seeks to provide superior customer
service as compared to incumbent service providers, with service features such
as a 24-hour-a-day call center and quality control system, on-time service
guarantees and bundled service offerings, providing the consumer with added
choice and convenience.

Recent Developments

     On February 20, 1998, RCN acquired Erols and on February 27, 1998, RCN
acquired Ultranet. With these acquisitions, RCN became a leading ISP in the
Boston to Washington, D.C. corridor, serving approximately 325,000 Internet
service customers. See "Business--The Acquisitions of Ultranet and Erols" and
"Business--RCN Services--Connections."

     Erols is a leading regional ISP with approximately 293,000 residential and
business subscribers as of December 31, 1997 in targeted markets, including New
York City, Philadelphia, Washington, D.C. and Boston. RCN expects to contribute
to Starpower the subscribers acquired in the acquisition of Erols located in the
Washington, D.C. area in which Starpower operates. The joint venture partners of
Starpower are currently negotiating the terms of such contribution. On February
20, 1998, approximately 61% of all of Erols' subscribers were located in the
relevant Washington, D.C. area. Erols currently operates 57 POPs throughout its
geographic markets, and also currently utilizes 42 "Virtual POPs," which permit
subscribers located adjacent to, but outside of the local calling areas of,
physical POPs to dial into the Erols network on a local basis through
arrangements with the relevant LEC. Erols offers a broad range of Internet-based
services, including (i) Global Trader(sm), Erols' turn-key e-commerce product
for small businesses, (ii) Internet security services, including security
consulting and virtual private networks, and (iii) Web hosting, design and
development services. RCN acquired Erols in exchange for consideration
consisting of $29.2 million in cash and 1,730,648 shares of RCN Common Stock
plus the assumption and repayment of approximately $5.8 million of debt
(including payment of accrued interest). See "Business--The Acquisitions of
Ultranet and Erols--Merger With Erols Internet, Inc."

     Ultranet is a leading ISP in the Boston area with more than 32,000
residential and business customers in New England. RCN contributed to its joint
venture with BECO the subscribers acquired in the acquisition of Ultranet
located in the Boston area in which the BECO joint venture operates as well as
1.36% (or all of Erols' subscribers located in the relevant Boston area) of the
subscribers acquired in the acquisition of Erols. On February 27, 1998,
approximately 27% of all of Ultranet's subscribers were located in the relevant
Boston area. Ultranet provides Internet service to over 500 schools, and is
presently building a network which will provide access throughout New
Hampshire's universities and colleges. Ultranet has a wide network of 42 POPs.
Services Ultranet offers to subscribers include (i) virtual hosting, which gives
customers a corporate presence on the Internet, (ii) firewall security, which
provides high quality control in monitoring access to documents and visitors to
the customer's websites, and (iii) UltraFax, which allows customers to send
faxes from their desktops. Ultranet also offers its customers access to its
network via an 800 number which allows access from every major city in the
world. RCN acquired Ultranet in exchange for consideration consisting of
approximately $7.9 million in cash and 890,384 shares of RCN Common Stock.
Ultranet had total revenues of approximately $6.7 million for the year ended
June 30, 1997. See "Business--The Acquisitions of Ultranet and Erols--Merger
With Ultranet Communications, Inc."

Industry Overview--Market Opportunities in Telecommunications

     Overview of Incumbent Service Providers

     The telecommunications industry today is dominated by the incumbent LECs
and cable television companies and by the IXCs. Typically, only the incumbent
LECs and cable television companies have a last mile connection to their
customers (with the exception of a small number of "competitive access
providers" (or "CAPs"), whose networks and operations have been targeted almost
exclusively at medium to large commercial users).

     The distribution networks and customer connections of the incumbent LECs
can typically be characterized as low capacity, high reliability systems based
upon copper twisted-pairs. Although telephone service has relatively modest
capacity requirements, the provisioning of switch-based usage is a complex and
difficult process. The incumbent LEC telephone networks were constructed over a
hundred-year period under a regulatory regime which placed a premium upon
reliability and universal service, but which did not make significant
advancement in terms of network or operating efficiency. While the incumbent
LECs have begun to expand the amount of fiber optic facilities in their
networks, the basic local exchange systems have remained largely unchanged and
are typically unable to deliver higher capacity services such as video or high
speed Internet connections. These limitations, together with the significant
investment imbedded in the existing systems and the magnitude of the costs of an
extensive upgrade of such systems, have discouraged the incumbent LECs from
expanding their service offerings or comprehensively deploying new networks.
Instead, the incumbent LECs have concentrated their development efforts
primarily on re-entering the long distance business (which can be done with a
relatively modest investment).

     The distribution networks and customer connections of cable television
operators can typically be characterized as one-way, medium to high bandwidth
systems with generally lower reliability and integrity than the incumbent LECs'
telephone networks. The initial construction phase of the cable networks was
characterized by the rapid building of a subscriber base and the cost-effective
coverage of a broad service area, rather than providing a framework for a wide
range of high-capacity services with the necessary reliability for delivery of
telephone services. Accordingly, most existing cable television systems do not
typically have the capacity or architecture to enter into the telephony
business, nor do their operators typically have the experience or infrastructure
to quickly or effectively enter into the provisioning of switch-based, usage
sensitive services.

     The data services industry is a relatively new and growing business segment
developed to meet consumer needs arising from the rapid growth of initially
simple services such as fax transmission to increasingly complex and capacity
consuming uses, such as local area networks and Internet access, video
teleconferencing and other high bandwidth applications. Increasingly, demand for
telecommunications services relating to data transmission will require higher
capacity platforms to deliver highly complex material (including interactive
applications) at speeds which will maximize and promote rather than inhibit the
utility of such services.

     Widespread Changes in Telecommunications Industry

     Both the telephone and cable television segments of the telecommunications
industry as well as overall network capacity requirements are currently
undergoing widespread changes brought about by, among other things, (i)
decisions of federal and state regulators which have opened the monopoly local
telephone and cable television markets to competition; (ii) the ensuing
transformation of the previously monopolistic telecommunications market
controlled by heavily regulated incumbents into a consumer-driven competitive
service industry; and (iii) the need for higher speed, higher capacity networks
to meet the increasing consumer demand for expanded telecommunications services
including broader video choices and high speed data and Internet services. The
convergence of these trends and the inherent limitations of most existing
networks have created opportunities for new types of communications companies
capable of providing a wide range of voice, video and data services through new
and advanced high speed, high capacity telecommunications networks.

     Opening of Telecommunications Markets

     Divestiture of the Bell System. Until the passage of recent federal
legislative reform and other state and federal regulatory efforts to expand
competition into the local telephone market, the structure of the U.S.
telecommunications industry was shaped principally by the 1984 court-supervised
divestiture of local telephone services from AT&T (the "Divestiture") and other
judicial and regulatory initiatives which were designed primarily to implement
structural and technical industry changes through which competition could
develop in the long distance market. Under this structure, the RBOCs and certain
other LECs were permitted to retain their monopolies in the provision of local
exchange services, but were required to connect their local subscribers to the
long distance services of AT&T and other IXCs. Under this regime, two distinct
industry segments developed; competitive IXCs, which offered subscribers long
distance telephone services between judicially defined local access and
transport areas ("LATAs"), and monopoly LECs, which offered subscribers local
and toll services within judicially defined LATAs, including connection (or
"access") to IXCs for interLATA long distance services. As a result, the
long-distance business became intensely competitive, with low barriers to entry
and many service providers competing in a commodity-type market, while providers
of local exchange services continued to face relatively little competition.

     Deregulation of Local Telephone Services. After the structural and
technical network changes were put in place following the Divestiture to give
IXCs other than AT&T "equal access" to the local exchange facilities of the
monopoly incumbent LECs, and with robust long distance competition began to
provide consumers with diverse services and lower rates, regulatory policy
gradually began to examine whether the competitive benefits which were being
experienced in the long distance marketplace as a result of Divestiture should
be expanded to local exchange services. While a small number of states and the
FCC had already adopted rules and regulations which opened certain limited and
discrete segments of the local exchange market to competition from CAPs and
CLECs offering primarily dedicated high-speed private line and some local
switching services to large business users, the passage of the 1996 Act in
February 1996 codified the pro-competitive policies on a national level and
required both the FCC and the state regulatory commissions to adopt dramatic and
sweeping changes in their rules and regulations in furtherance of those
policies. The 1996 Act required regulators to remove market entry barriers and
to enable companies like RCN to become full service providers of local telephone
service by, among other things, mandating that the incumbent LECs provide
interconnection and competitively priced network facilities to competitors. In
addition, the 1996 Act permits RBOCs to offer long distance interLATA services
in competition with IXCs once they have demonstrated that they have implemented
changes to permit economically efficient competition in their local markets for
both business and residential services. Re-entry into the long distance market
has become a central objective to all of the incumbent LECs due to the
relatively modest capital investment required and the prospect of attaining
substantial operating efficiencies in offering these services, as opposed to the
extensive network overhaul and the magnitude of the capital requirements that
would be necessary for the incumbent LECs to enter into video or other
high-bandwidth services using their own facilities. Although the incumbent LECs
have begun to expand the amount of fiber facilities in their networks, the
incumbent LEC networks are still largely copper wire-based, which limits their
ability to expand into video programming and other high capacity services.

     Deregulation of Cable Television. Unlike the local telephone market, the
cable television market is not subject to regulatory or statutory prohibitions
on competition. Nevertheless, competition to incumbent franchised cable
television operators has developed in only a handful of markets nationwide.
Because of the lack of any meaningful competition in 1992, Congress passed
legislation providing for the regulation of certain cable rates. Subsequently,
as part of its general goal of supplanting regulation with competition, the 1996
Act took further steps to provide alternative regulatory structures to encourage
entry into the multichannel video programming distribution market. Among other
things, the 1996 Act required that the FCC adopt rules to implement a new "Open
Video Systems" ("OVS") structure for telephone companies or others to deliver
video services through their networks. The OVS structure was specifically
designed by the Congress and the FCC to encourage more competition to local
cable television providers. Among other efforts to remove barriers which had
discouraged competition from developing in the video market, the 1996 Act
specifies that OVS providers, and any video programming providers ("VPPs") that
lease facilities from such OVS providers, may offer video services without
obtaining a local cable television franchise. Certain other obligations similar
to those placed on cable television operators, such as a gross receipts fee and
the transmission of public, educational and government programming, will also
apply to OVS providers.

     Demand for High Speed, High Capacity Telecommunications Services. The
Company believes that, as a result of increased competition and the development
of new telecommunications products and services, the telecommunications market
has become increasingly consumer-driven, and pricing, service quality and
customer service are becoming more important than loyalty to the incumbent
providers. However, due to the inherent bandwidth limitations of the existing
copper wire networks, the incumbent LECs would be required to undertake
significant capital expenditures in order to offer high speed, high capacity
services and, to date, have instead focused primarily on reentering the long
distance business which can be provisioned over their existing facilities with
modest investment. Similarly, constraints of traditional coaxial cable
television systems and lack of necessary infrastructure have limited cable
operators from offering switch-based, usage sensitive services such as telephone
and certain data services. As a result, newly constructed facilities such as
RCN's advanced fiber optic networks provide a superior platform for providing
cost effective, high speed, high capacity telecommunications and enhanced
telecommunications services.

     The RCN Opportunity. The incumbent local telephone and cable television
providers have to date generally been slow to expand their services beyond their
traditional lines of business due primarily to the fundamental limitations of
their existing networks. In particular, the LECs have generally not offered
video programming services, nor have the incumbent cable operators generally
entered the telephone services market. RCN believes that it will be able to
offer a single-source package of bundled voice, video and data services which
are not yet generally available from any incumbent telephone, cable or other
providers. In addition, most of the other new competitive entrants, including
most CLECs, have focused almost exclusively on providing telephone service to
medium to large commercial customers and have tailored the coverage area of
their networks and the configuration of their business operations to provision
services accordingly. As a result, CLECs have generally not yet begun to offer
their telephone services to the residential marketplace, or expanded their
offerings to include video programming services. Similarly, while a number of
companies have begun to market wireless alternatives to cable television
service, those companies have not generally begun to offer telephone services to
their customers. Accordingly, RCN believes that it is well-positioned to take
advantage of the new regulatory and market environment. By combining the
enhanced telephone and data services offered by CLECs with high quality video
programming, RCN acts as a single source provider of a wide range of voice,
video and data services to the residential market as well as to select
institutional and commercial customers with ready access to its facilities.
RCN's integrated service offerings are available either individually or in
bundled packages, providing the consumer with added choice and convenience.
RCN's bundled services are provided using state-of-the-art technology and are
generally provided at competitive prices and with superior customer service as
compared to RCN's existing competitors. As such, RCN believes that it is poised
to become an effective competitor in each of its markets.

RCN Services

     RCN provides a wide range of local and long distance telephone, video
programming and data services, both individually and in bundled service options.

     RCN provides these services through a range of facilities including its
advanced fiber optic networks in New York City and Boston, a wireless video
system in New York City, its hybrid fiber/coaxial cable systems in the states of
New York (outside New York City), New Jersey and Pennsylvania, and resale local
and long distance telephony services.

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

(1)  Because RCN delivers multiple services, the Company accounts for its
     customer activity by the number of individual local telephone, video
     programming or Internet access services, or "connections", purchased.
     Consequently, a single customer purchasing local telephone, video
     programming and Internet access constitutes three connections.

(2)  Includes approximately 38,000 wireless connections. RCN classifies
     connections provided over advanced fiber optic networks within the "Other"
     category until the relevant network is capable of providing voice, video
     and data services, including local telephone service through an RCN switch.
     "Other" also includes, among other things, wireline video connections
     serving the University of Delaware (4,474 connections at December 31,
     1997).

(3)  Reflects Internet connections acquired in connection with the Erols and
     Ultranet acquisitions. RCN expects to contribute to Starpower, the joint
     venture with Pepco Communications, the subscribers acquired in the
     acquisition of Erols located in the Washington, D.C. area in which
     Starpower operates. The joint venture partners of Starpower are currently
     negotiating the terms of such contribution. RCN contributed to its joint
     venture with BECO the subscribers acquired in the acquisition of Ultranet
     located in the Boston area in which the BECO joint venture operates as well
     as 1.36% of the subscribers acquired in the acquisition of Erols. Starpower
     is accounted for under the equity method of accounting and the BECO joint
     venture is accounted for on a consolidated basis. See "--The Acquisitions
     of Ultranet and Erols."

(4)  In August 1997, RCN commenced offering resold local phone service, long
     distance and Internet access to customers in the area served by its Hybrid
     Fiber/Coaxial Cable Systems in the Lehigh Valley area.

     Set forth below is a brief description of RCN's services:

     Voice. RCN offers full-featured local exchange telephone service, including
standard dial tone access, enhanced 911 access, operator services and directory
assistance in competition with the incumbent local exchange providers and CLECs.
In addition, RCN offers a wide range of value-added services, including call
forwarding, call waiting, conference calling, speed dial, calling card,
800-numbers and voice mail. RCN also provides Centrex service and associated
features. RCN's local telephone rates are generally competitive with the rates
charged by the incumbent providers. At December 31, 1997 RCN had approximately
3,200 telephone service connections on its advanced fiber optic networks and
approximately 24,900 customers for resold telephone service.

     Through its RCN Commercial division ("RCN Commercial"), RCN provides long
distance telephone services, including outbound, inbound, calling card, and
operator services. These services are offered to residential and business
customers. As of December 31, 1997 RCN Commercial had approximately 13,595
customers. In the future RCN intends to offer long distance telephone service
predominantly to customers whom it expects will eventually be connected to its
own facilities.

     Video Services. RCN offers a diverse line-up of high quality basic, premium
and pay-per-view video programming. Depending on the system, RCN offers from 61
to 110 channels. RCN's basic video programming package provides extensive
channel selection featuring all major cable and broadcast networks. RCN's
premium services include HBO, Cinemax, Showtime and The Movie Channel, as well
as supplementary channels such as HBO 2, HBO 3 and Cinemax 2. RCN's StarCinema,
available on the Company's advanced fiber optic networks, utilizes the latest
"impulse" technology allowing convenient impulse pay-per-view ordering of the
latest hit movies and special events instantly from the customer's remote. RCN's
"Music Choice" offers 30 different commercial-free music channels delivered to
the customer's stereo in digital CD quality sound.

     As of December 31, 1997 RCN had approximately 11,800 subscribers for its
video programming services provided over advanced fiber optic networks in New
York City and Boston. As of such date, RCN also had approximately 38,000
connections attributable to the wireless video system and approximately 184,900
connections attributable to the hybrid fiber/coaxial cable systems.

     RCN also acts as a provider of DirecTV direct broadcast satellite service
to multiple dwelling units ("MDUs") in New York City. DirecTV allows RCN to
deliver an additional 175 channels of programming including exclusive sports
programming.

     Internet Access and Data Transmission. RCN's StarPass Internet service
provides access for personal computers to RCN's advanced fiber optic network for
a reliable high speed connection to provide access to electronic mail, World
Wide Web, Internet chat lines and newsgroups and remote access and file transfer
services. RCN provides data transmission services over its advanced fiber optic
network either via two-way dial-up modem over traditional telephone lines or via
cable modem utilizing RCN's high capacity network. RCN also offers private line
point-to-point data transmission services such as DS-1 and DS-3 with the
capability to provide higher speed connections as well. Following the recent
Erols and Ultranet acquisitions, RCN believes it is the largest regional
provider of Internet services in the Northeast.

     Migration of Customers to Advanced Fiber Networks

     RCN provides wireless video services to customers located near its advanced
fiber optic network in New York City and provides resale telephone service with
a view to extending the advanced fiber optic network and fully activating RCN's
own telephone switches to service many of those customers. As RCN's advanced
fiber optic network is extended into these areas or buildings, customers
receiving wireless video service in New York City will be switched to the
advanced fiber optic network from the wireless video network, and the wireless
video equipment will be used to provide service to other customers in
off-network premises. Similarly, as the advanced fiber optic network is
developed and switches are deployed, voice customers will be switched to the
advanced fiber optic network from resale accounts, thereby allowing RCN to gain
additional revenue (and larger margins) from originating and terminating access
fees and to control the related services and service quality.

Strategic Relationships

     RCN has developed a number of strategic alliances and relationships in
order to provide it with early entry and to reduce the cost of entry into the
market for telecommunications services. RCN expects to continue to pursue
opportunities that may be afforded by entering into strategic alliances to
facilitate network expansion and entry into new markets.

     Relationship with MFS/WorldCom

     RCN commenced development of its communications network by entering into
lease arrangements with MFS/WorldCom, allowing RCN initial access to fiber optic
networks owned by MFS/WorldCom in Boston and New York City. Through a
construction cooperation agreement with MFS/WorldCom under which MFS/WorldCom
has agreed to install segments of RCN's network, RCN has also been able to
reduce the cost and time of installation of fiber in New York City and Boston.
Under certain other agreements, MFS/WorldCom has also agreed to support RCN's
efforts to implement OVS Service and to provide RCN with local switched voice
and data services for RCN's voice service business. The following describes the
terms of the main agreements between MFS/WorldCom and RCN:

     Fiber Agreements. RCN, through its affiliates, has entered into Fiber
Agreements (the "Fiber Agreements"), each dated May 8, 1997, with MFS/WorldCom,
which owns or has the right to use certain fiber optic network facilities (the
"Fiber Optic Facilities") in the Boston, Massachusetts and Borough of Manhattan,
New York, New York markets (the "Service Areas"). Pursuant to the Fiber
Agreements, MFS/WorldCom (i) will construct and provide extensions connecting
the Fiber Optic Facilities to buildings designated by RCN (the "Extensions") and
(ii) has granted to RCN the right to use certain dedicated fibers in the Fiber
Optic Facilities and the Extensions, except that RCN may not use such facilities
to deliver telephone services to commercial customers in the Service Areas. In
return, RCN has reimbursed MFS/WorldCom for the costs MFS/WorldCom incurred to
install, construct and acquire the Fiber Optic Facilities constructed prior to
March 31, 1997. RCN has further agreed to pay all of the costs MFS/WorldCom
incurs to (i) install, construct and acquire the Fiber Optic Facilities
constructed between March 31, 1997 and May 8, 1998 and the Extensions, and (ii)
maintain, and support RCN's use of, the Fiber Optic Facilities and the
Extensions. Unless earlier terminated upon the occurrence of certain events set
forth therein, including a change of control of RCN, the Fiber Agreements
terminate by their terms on January 1, 2007, provided that (i) at such time the
parties may agree to extend the Fiber Agreements for up to 10 years or enter
into other alternative arrangements, and (ii) under certain circumstances,
MFS/WorldCom is required to transfer the Extensions to RCN.

     BECO Joint Venture

     In September 1996, RCN and BECO, through wholly owned subsidiaries, entered
into a letter of intent to form a joint venture to utilize 126 fiber miles of
BECO's fiber optic network to deliver RCN's comprehensive communications package
in Greater Boston. The venture, in the form of an unregulated entity with a term
expiring in the year 2060, was formed pursuant to a joint venture agreement
dated December 23, 1996 (the "Boston Joint Venture Agreement") providing for the
organization and operation of RCN-BECOCOM, LLC ("RCN-BECOCOM"). RCN-BECOCOM is a
Massachusetts limited liability company organized to own and operate an advanced
fiber optic telecommunications network (the "Network") and to provide, in the
market in and around Boston, Massachusetts (the "Boston Market"), voice, video
and data services, as well as the communications support component of energy
related customer services offered by BECO (collectively, the "Boston Services").
RCN, through RCN Massachusetts, owns 51% of the equity interest in RCN-BECOCOM
and BECO, through a subsidiary, owns the remaining 49% interest. This joint
venture with BECO is reflected on RCN's financial statements on a consolidated
basis.

     The closing of the transactions contemplated by the Boston Joint Venture
Agreement occurred on June 17, 1997. At the closing, (i) RCN transferred to
RCN-BECOCOM its business of providing Boston Services; (ii) BECO transferred to
RCN-BECOCOM access to and use of certain existing BECO facilities; (iii) RCN and
BECO made initial cash capital contributions to RCN-BECOCOM; and (iv) the
parties and/or their affiliates executed and delivered (a) the Amended and
Restated Operating Agreement of RCN-BECOCOM (the "BECO Operating Agreement");
(b) the Construction and Indefeasible Right of Use Agreement (the "IRU
Agreement"); (c) the Management Agreement (the "Management Agreement"); (d) the
Exchange Agreement (the "Exchange Agreement"); and (e) the Joint Investment and
Noncompetition Agreement (the "Joint Investment Agreement").

     Pursuant to the BECO Operating Agreement, RCN and BECO are required to make
any additional capital contributions required by RCN-BECOCOM's annual budget on
a 51%/49% basis. The annual budget will be prepared by RCN and is subject to
review by each member of RCN-BECOCOM. RCN will manage the business of
RCN-BECOCOM; however, certain extra ordinary actions require the consent of both
parties. In addition, if a deadlock arises relating to a merger, reorganization,
issuances of equity, liquidation or bankruptcy, amendments to the organizational
documents or an expansion of operations of RCN-BECOCOM beyond those contemplated
by the BECO Operating Agreement, the disputing party will either sell its
interest or purchase the other party's interest in the joint venture. In the
event of a deadlock relating to other fundamental business actions or relating
to the annual budget, the matter will be submitted to arbitration. Neither RCN
nor BECO may transfer its interest in RCN-BECOCOM until June 17, 2000 without
the other's written consent. After such date, each party has the right to
purchase the interest proposed to be sold by the other party. If a party
proposes to sell more than 33% of its interest, the other party has "tag-along"
rights to sell a proportionate share of its interest. In the event a member's
interest becomes less than 25%, the other members have the option to purchase
such interest at fair market value. Upon a change in control of either RCN
Massachusetts or BECOCOM, the other party has the right to purchase all of the
equity interest in RCN-BECOCOM for fair market value, as determined by an
appraisal proceeding.

     RCN will manage the business of RCN-BECOCOM pursuant to the terms of the
Management Agreement and, in consideration therefor, will receive reimbursement
for its reasonable costs, and a performance-based fee (based on factors
including the number of subscribers and operating cash flow) to be determined by
agreement of RCN and RCN-BECOCOM. The initial term of the agreement expires on
December 31, 2001. The agreement provides for automatic successive three-year
renewal periods, unless notice is given ninety days before the end of the
period.

     Pursuant to the IRU Agreement, BECO will, for certain agreed upon fees, (i)
provide construction services to build out the Network, (ii) make available to
RCN-BECOCOM (a) all of the available capacity of BECO's existing fiber backbone,
and (b) the ability to use BECO's real estate, poles, easements and other
interests for the construction and operation of the Network and (iii) maintain
the Network. BECO's construction obligations expire on June 17, 2007 and the
term of the IRU Agreement generally expires on December 31, 2060. One year
before each respective expiration date, BECO agrees to commence good-faith
negotiations to extend construction obligations beyond June 17, 2007 and to
allow continued use of BECO's facilities beyond December 31, 2060.

     Under the Joint Investment Agreement, BECO will have the right to acquire
up to a 20% equity interest in any joint venture between RCN and an electric
utility company formed to provide any services similar to the Boston Services in
New England outside the Boston Market. BECO's joint investment right shall
terminate (i) upon BECO's stake in RCN-BECOCOM dropping below a 1/3 interest and
(ii) on the later to occur of (a) June 17, 2002 or (b) two years after RCN's
stake in RCN-BECOCOM falls below a 1/3 interest. The agreement also provides
that neither RCN, BECO nor their affiliates will be permitted to be involved in
any other enterprise providing services similar to the Boston Services in the
Boston Market. This covenant not to compete will survive for a period of two
years after either party is no longer a member of RCN-BECOCOM.

     Pursuant to the Exchange Agreement, BECO had the right at the time of the
Distribution, and has the right every two years thereafter, to convert its
ownership interest in RCN-BECOCOM into the Common Stock of RCN pursuant to
specific terms and conditions, including exercise periods, appraisal procedures
and restrictions specifically set forth in the Exchange Agreement. Although BECO
exercised its conversion right, BECO remains obligated to make 49% of all cash
contributions by the parties and any cash contributions made after conversion
will result in it owning a portion of RCN-BECOCOM based on the value of
RCN-BECOCOM at the time of the contribution. BECO may exercise its conversion
rights in whole or in part from time to time. BECO has notified RCN that it has
elected to exercise its option to the full extent permitted by the Exchange
Agreement with respect to 1997. RCN and BECO are presently in discussions with
respect to the calculation of the agreed upon value for the exercise of such
option. BECO's right to convert its joint venture interest into Company Common
Stock is subject to certain limitations designed to ensure that the conversion
does not jeopardize the tax free nature of the Distribution. In the event BECO
is unable to convert any portion of its interest as a result of such
limitations, BECO has the right to require RCN to purchase such portion. Subject
to certain restrictions set forth in the Exchange Agreement, BECO will also be
entitled, upon exchanging its investment interest in RCN-BECOCOM for Company
Common Stock, to customary registration rights with respect to such shares.

     RCN expects to benefit from the ability to utilize BECO's large fiber optic
network, its focus on innovative technology, its sales and marketing expertise
and its reach into the market. In the future, the venture may expand into energy
management and property monitoring services. Starting in Boston, the joint
venture partners will consider further expansion into surrounding markets. RCN
anticipates that as a result of its access to the extensive BECO network, RCN's
reliance on and utilization of MFS/WorldCom facilities in Boston will be reduced
significantly.

     Starpower Joint Venture

     On August 1, 1997, RCN Telecom Services Inc., a subsidiary of RCN, and
Potomac Capital Investment Corporation ("PCI"), a wholly owned subsidiary of
PEPCO, entered into a letter of intent (the "Letter of Intent") to form a joint
venture which will own and operate a communications network to provide voice,
video, data and other communications services to residential and commercial
customers in the greater Washington, D.C., Virginia and Maryland area (the
"Washington, D.C. Market"). Starpower, an unregulated limited liability company
with a perpetual term, was formed on October 28, 1997 by RCN Telecom Services of
Washington, D.C., Inc. ("RCN Washington") and Pepco Communications. Starpower
was formed to construct, own, lease, operate and market a network for the
selling of voice, video, data and other telecommunications services (the
"Relevant Business") to all potential commercial and residential customers in
the Washington, D.C. Market. RCN, through RCN Washington, owns 50% of the equity
interest in Starpower and PCI, through Pepco Communications, owns the remaining
50% interest. Starpower is accounted for under the equity method of accounting.

     The closing (the "Starpower Closing") of the Starpower joint venture
occurred on December 19, 1997. At the closing, RCN Washington transferred to
Starpower all its right, title and interest in and to (i) all customer accounts
of RCN Long Distance in the Washington, D.C. Market, (ii) its business plan in
the Washington, D.C. Market and experience with respect to the Relevant
Business, (iii) all building access agreements covering any property located in
the Washington, D.C. Market, (iv) the Support Services Agreement (as described
below) and (v) the benefit of certain agreements pursuant to the Assignment of
Benefits Agreement (as described below). The documents signed at the Starpower
Closing were the Amended and Restated Operating Agreement of Starpower dated as
of December 18, 1997 by and between Pepco Communications and RCN Washington
("Starpower Operating Agreement"), Fiber Use Agreement dated as of December 18,
1997 between PEPCO and Starpower ("Fiber Use Agreement"), Agency Agreement dated
as of December 18, 1997 by and between RCN Washington, RCN Telecom Services of
Maryland, Inc., RCN Telecom Services of Virginia, Inc. and Starpower ("Agency
Agreement"), Non-competition Agreement dated as of December 18, 1997 by and
among RCN Telecom Services, Inc., PCI and Starpower ("Non-competition
Agreement"), Assignment of Benefits Agreement dated as of December 18, 1997 by
and between RCN Washington and Starpower ("Assignment of Benefits Agreement"),
Support Services Agreement dated as of December 18, 1997 by and between RCN
Operating Services, Inc. and Starpower ("Support Services Agreement"), Guarantee
dated as of December 18, 1997 by PCI on behalf of Pepco Communications in favor
of Starpower, Guarantee dated as of December 18, 1997 by RCN on behalf of RCN
Washington and other RCN obligors in favor of Starpower and Contribution
Agreement dated as of December 18, 1997 by and between RCN Washington. and
Starpower ("Contribution Agreement"). RCN Washington and Pepco Communications
also each paid $12.5 million in cash in January 1998 as their initial capital
contributions.

     Pursuant to the Starpower Operating Agreement, RCN Washington and Pepco
Communications are each required to make additional capital contributions in
accordance with a schedule set forth in such agreement on a 50%/50% basis.
Failure of either RCN Washington or Pepco Communications to make a scheduled
capital contribution or to vote in favor of certain additional capital
contributions may result in the recalculation of equity interests. The business
and affairs of Starpower is to be managed by RCN Washington and Pepco
Communications. So long as RCN Washington and Pepco Communications maintain a
50%/50% equity interest in the joint venture, each of RCN Washington and Pepco
Communications will appoint three members to the operating committee, the
approval of which is required for any business action. Certain fundamental
business actions, such as mergers, acquisitions, sales of substantially all of
the assets, liquidation and amendments to the certificate of organization or any
agreement signed at the Starpower Closing, require the unanimous approval of the
operating committee regardless of whether the parties continue to maintain a
50%/50% ownership interest. Failure to reach agreement may trigger a deadlock
event. In the event a deadlock arises within the first three years of the joint
venture, the proposed action shall be deemed rejected. If the deadlock arises
thereafter, the disputing party may give a notice to the other party offering to
sell its membership or to purchase all membership interests from the other
party; the offeree has the obligation to elect to buy or sell its interest.
Subject to certain exceptions, neither RCN Washington nor Pepco Communications
may sell any interest in Starpower for four years. Thereafter, RCN Washington or
Pepco Communications may sell any of its membership interests with the written
consent of the other subject to a right of first offer by the other party. RCN
Washington shall be restricted from transferring its interest if Pepco
Communications can demonstrate that such assignment would have a material
adverse impact on Starpower's business. Upon a change of control of RCN
Washington or Pepco Communications, which the other party has reason to believe
will have a material adverse effect on Starpower, the other party may offer to
sell its membership interests or to acquire such party's membership interests or
accept the change of control. The offeree has the right to elect to buy or sell
its interest. If a party proposes to sell its interest to a third party, the
other party has "tag-along" rights to sell a proportionate share of its
interest. Both RCN Washington and Pepco Communications may transfer their
membership interests to certain affiliates.

     Under the Fiber Use Agreement, PEPCO agreed, for certain agreed upon fees,
(i) to provide construction services to develop a network and (ii) to grant
Starpower an indefeasible right of use of certain facilities and an irrevocable
right to install, maintain, use and operate its strand fiber connections to
leased facilities. Starpower has the right, at the end of the term, to purchase
not less than the whole network at the fair market value less the amount
previously paid by Starpower with respect to such facilities. The initial term
is ten years and the agreement may be renewed four times.

     Under the Support Services Agreement, a subsidiary of RCN will provide
support services including customer service, billing, marketing, and certain
administrative, accounting and technical support services, each of which shall
be provided at cost. The Support Services Agreement also contains certain
indemnity provisions.

     Under the Non-competition Agreement, for so long as either RCN Washington
or Pepco Communications owns an interest in Starpower, neither party nor any of
their affiliates may compete with any Relevant Business in the Washington, D.C.
Market. Neither RCN Washington nor Pepco Communications shall attempt to
solicit, divert or accept business from the customers of Starpower for any
Relevant Business in the Washington, D.C. Market or solicit any individual who
is employed by Starpower.

     Starpower agreed, in the Agency Agreement, to serve as RCN Washington's
exclusive agent for the provision of telephony services in the Washington, D.C.
Market until Starpower receives sufficient authorization for it to provide
telephony services in the Washington, D.C. Market. All revenues and customers
under this Agency Agreement belong to Starpower. Starpower must indemnify RCN
Washington for any tax liability resulting from its obligations under this
Agency Agreement. The Agency Agreement also contains certain other indemnity
provisions.

     Pursuant to the Assignment of Benefits Agreement, RCN Washington assigned
the benefits of all of the agreements (the "Assigned Agreements") with suppliers
of programming and entertainment, voice, video and data services,
telecommunications equipment and other products and services useful in the
conduct of the Relevant Business in the Washington, D.C. Market to Starpower.
RCN Washington may not transfer or assign its interest in the Assigned
Agreements if doing so would have a material adverse effect on Starpower's
ability to conduct the Relevant Business in the Washington, D.C. Market. In
addition, RCN Washington may not amend, modify or assign the Assigned Agreements
without the prior written consent of Starpower and Starpower has the right to
terminate any agreement amended, modified or assigned without its consent. RCN
Washington has agreed to take all reasonable steps necessary to obtain consent
for Starpower to use programming agreements prior to the date Starpower begins
offering OVS services. The Assignment of Benefits Agreement expires on December
19, 1998 and Starpower has certain renewal rights. Starpower may terminate the
Assignment of Benefits Agreement on 60 days notice.

     RCN has agreed to unconditionally guarantee the due and punctual
performance and discharge all of its affiliates' material covenants, warranties,
undertakings and other obligations under the agreements signed at the Starpower
Closing. PCI has agreed to unconditionally guarantee the due and punctual
performance and discharge by Pepco Communications of all its material covenants,
warranties, undertakings and other obligations under the Starpower Operating
Agreement.

The Acquisition of Ultranet and Erols

     Merger with Erols Internet, Inc.

     On January 21, 1998, RCN entered into the Agreement and Plan of Merger (the
"Erols Merger Agreement") among RCN, Erols, Erol Onaran, Gold & Appel Transfer,
S.A., a British Virgin Islands corporation ("Gold & Appel"), and ENET Holding,
Inc., a Delaware corporation and a wholly owned subsidiary of RCN ("ENET"), to
acquire all of the outstanding shares of common stock of Erols. On February 20,
1998, Erols merged with and into ENET (the "Erols Merger"), with ENET as the
surviving corporation. The total consideration paid by RCN in the Erols Merger
consisted of $29.2 million in cash and 1,730,648 shares of RCN Common Stock plus
the assumption and repayment of approximately $5.8 million of debt (including
payment of accrued interest).

     At the effective time of the Erols Merger, 998,719 outstanding options to
purchase shares of Erols common stock issued to persons who were employees of
Erols at such effective time, with an average exercise price of $2.40 per share
of Erols common stock, were canceled and RCN issued in exchange therefor options
to purchase 699,104 shares of RCN Common Stock having an average exercise price
of $3.424 per share.

     The Erols Merger Agreement contains customary representations, warranties,
and covenants by each party, which representations and warranties will survive
until March 31, 1999, except for certain specified representations and
warranties which will survive indefinitely or until the expiration of the
applicable statute of limitations. Pursuant to the Erols Merger Agreement, each
party has agreed to provide indemnification from damages arising out of any
misrepresentation or breach of warranty, covenant or agreement made or to be
performed by such party pursuant to the Erols Merger Agreement. In addition,
Erol Onaran has agreed to provide indemnification from damages arising out of
any misrepresentation or breach of warranty, covenant or agreement made or to be
performed by Erols on or before the Effective Time, subject to certain
thresholds and limitations, and arising from certain matters set forth in the
Erols Merger Agreement.

     Pursuant to the Erols Merger Agreement, at the Effective Time both an
escrow agreement (the "Erols Escrow Agreement") and a registration rights
agreement (the "Erols Registration Rights Agreement") were executed and
delivered. Under the terms of the Erols Escrow Agreement, RCN delivered to the
Erols Escrow Agent an aggregate of approximately $5.84 million in cash and
93,210 shares of RCN Common Stock to be held, invested and distributed by the
Erols Escrow Agent pursuant to the Erols Escrow Agreement. Under the terms of
the Erols Registration Rights Agreement, Erol Onaran and Gold & Appel each
received customary demand and piggy-back registration rights, subject to certain
limitations as set forth in the Erols Registration Rights Agreement.

     Merger With Ultranet Communications, Inc.

     On January 21, 1998, RCN, UNET Holdings, Inc. and Ultranet entered into an
Agreement and Plan of Merger (the "Ultranet Merger Agreement"). The total
consideration for the acquisition consisted of approximately $7.9 million in
cash and 890,384 shares of RCN Common Stock.

     At the Effective Time, 63,500 outstanding options to purchase shares of
Ultranet common stock issued to persons who were employees of Ultranet at such
effective time, with an average exercise price of $3.363 per share, were
canceled and RCN issued in exchange therefor options to purchase 117,052 shares
of RCN Common Stock having an average exercise price of $1.8245 per share. In
the event an option holder is terminated without cause, such option holder's
options will vest and will be exercisable for a period of six months following
termination. RCN is obligated to honor all obligations of Ultranet under
employment agreements as contemplated in the Ultranet Merger Agreement following
the acquisition.

     RCN also agreed to indemnify Ultranet and its directors, officers and
stockholders from and against liabilities or expenses incurred (i) in connection
with the severance benefits under any severance arrangement applying to any
former employee of Ultranet employed by RCN after the Ultranet Merger is
consummated, (ii) relating to a former employee's employment and/or termination
by RCN after the Ultranet Merger is consummated and (iii) incurred by an
indemnified person with respect thereto.

     Indemnification and Noncompetition Agreement

     Certain stockholders holding at least 95% of the Ultranet common stock,
Series A Preferred Stock and Series B Preferred Stock executed an
Indemnification and Noncompetition Agreement (the "Indemnification Agreement")
which provides that certain representations and warranties included in the
Ultranet Merger Agreement will survive the consummation of the merger. Such
stockholders agree to indemnify RCN, severally and on a pro rata basis, and RCN
agrees to indemnify the stockholders against all losses incurred by any of them
arising out of any breach of any tax representation in the Ultranet Merger
Agreement insofar as such breach causes the merger not to qualify as a
reorganization or any material failure to perform any of its covenants or
agreements contained in the Ultranet Merger Agreement. The maximum amount of
indemnification by the stockholders on the one hand and by RCN on the other hand
is $7.5 million plus certain amounts up to $2.5 million with respect to breach
of tax representations.

     The Indemnification Agreement provides that the stockholders will not
knowingly take any action which would cause the merger not to qualify as a
reorganization. Certain employees also agree not to engage in any activity which
would compete with Ultranet in the geographic region identified as the
"Boston-Washington" corridor for a period ending the earlier of five years after
the consummation of the merger or one year after his or her termination (or two
years in the case of termination for cause or voluntary termination).

     Contribution of Erols' and Ultranet's Subscribers

     RCN expects to contribute to Starpower, the joint venture with Pepco
Communications, the subscribers acquired in the acquisition of Erols located in
the Washington, D.C. area in which Starpower operates. The joint venture
partners of Starpower are currently negotiating the terms of such contribution.
On February 20, 1998, approximately 61% of all of Erols' subscribers were
located in the relevant Washington, D.C. area. RCN anticipates that Pepco
Communications will make a contribution equal to the value of such subscribers.

     RCN contributed to its joint venture with BECO the subscribers acquired in
the acquisition of Ultranet located in the Boston area as well as 1.36% (or all
of Erols' subscribers located in the relevant Boston area) of the subscribers
acquired in the acquisition of Erols. On February 27, 1998, approximately 27% of
all of Ultranet's subscribers were located in the relevant Boston area. BECO has
made a corresponding contribution to the joint venture in the form of a note in
the principal amount of 49/51 of the agreed value of the subscribers contributed
by RCN.

The Delivery Platforms

     Overview of Advanced Fiber Optic Networks

     RCN's advanced fiber optic networks in Boston and New York City are, and
RCN expects that its future networks will be, designed to support voice, video
and data services via a switched, fiber-rich network architecture. The Company's
full service advanced fiber optic networks in Boston and New York City consist
of owned or leased fiber optic cables, local and long distance digital switches,
video headends, video and voice transmission and distribution equipment and
associated wiring and network termination equipment. The Company's local
telephone switching network (consisting of Lucent 5ESS-2000 switches) is
installed and fully operational in Boston and in New York City. The networks'
leased fiber optic cables make up the fiber backbone, which acts as the common
signal transport medium for both digital signals (voice and data) and analog
signals (video). In both New York City and Boston, the digital backbone
transmission network utilizes synchronous optical network ("SONET") self-healing
rings that provide high speed, redundant connections for the delivery of RCN's
voice and data services. Facility connections from the backbone network to
individual buildings or service areas are provided by either leased facilities
provided by MFS/WorldCom, BECO or the incumbent LEC, or through RCN-owned fiber.
This fiber backbone includes over 5,267 fiber miles in New York City and over
9,347 fiber miles in Boston. RCN owns two switches (one in Boston and one in New
York City) and two General Instrument video headends that are installed and in
service in both Boston and New York City. As of December 31, 1997 RCN had
connected 493 buildings (424 in NYC and 69 in Boston) to its facilities.

     Fiber optic systems are suitable for transmission of digitized voice, data,
video or a combination of these types of information. The main benefits of
deploying fiber in place of traditional coaxial cable or copper wire result from
its greater capacity, increased functionality, smaller size and decreased
requirements for periodic amplification of the signal. These factors contribute
to lower installation and maintenance costs and increase the variety and quality
of the service offerings. The inherent bandwidth limitations of twisted pair
copper wire historically used in telephone networks present a substantial
obstacle to the use of existing telephone networks to provide video programming
services. Although coaxial cable provides substantially greater bandwidth than
twisted pair copper wire, fiber optic cable provides substantially greater
bandwidth than coaxial cable. Consequently, newly constructed fiber networks
such as RCN's provide a superior platform for delivering high speed, high
capacity voice, video and data services as compared to systems based on copper
wire or coaxial cable networks.

     The fiber cable utilized by RCN's networks has the increased capacity and
bandwidth necessary for complex data and video transmission. The fiber optic
cable typically contains between 12 and 288 fiber strands, each of which is
capable of providing many telecommunications channels or "circuits". Depending
on transmission electronics, a single pair of glass fibers on RCN's networks
currently can transmit tens of thousands of simultaneous voice conversations,
whereas even with multiplexing equipment a typical pair of copper wires can
carry a maximum of 24 simultaneous conversations. Although the LECs commonly use
copper wire in their networks, they are currently deploying fiber optic cable to
upgrade portions of their copper based network, particularly in areas served by
RCN. RCN expects that continuing development in communications equipment will
increase the capacity of each optical fiber, thereby providing even more
capacity at relatively low incremental cost.

     As the Company's network is further developed, it will be dependent on
certain strategic alliances and other arrangements in order to provide the full
range of its telecommunication service offerings. These relationships include
RCN's arrangements with MFS/WorldCom to lease portions of MFS/WorldCom's fiber
optic network in New York City and Boston, RCN's joint venture with BECO under
which the Company has access to BECO's extensive fiber optic network in Greater
Boston, the Starpower joint venture with Pepco Communications, a subsidiary of
PEPCO, and RCN's arrangements to lease Bell Atlantic unbundled local loop and
T-1 facilities. See "Strategic Relationships" and "Voice Services Advanced Fiber
OpticNetworks." Any disruption of these arrangements and relationships could
have a material adverse effect on the Company.

     Voice Services

     Advanced Fiber Optic Networks. The Company's advanced fiber optic networks
in New York City and Boston utilize a voice network that supports both switched
and non-switched (private line) services. Individual buildings are connected to
the network backbone via fiber extensions that are generally terminated on SONET
equipment, which provide redundant and fail-safe interconnection between the
building and the RCN central office or switch location. In situations where
fiber extensions are not yet available, interim facility connections can be
provided by leasing special access facilities through a leasing arrangement with
MFS/WorldCom or the incumbent LEC. In this regard, RCN has in place arrangements
which allow it to lease certain facilities owned by the incumbent LECs
(unbundled local loops and T-1 facilities) to provide voice services. This
enables RCN to provide voice and data services to off-net subscribers who are
not physically connected to RCN's advanced fiber optic network. As RCN's network
expands to reach more areas within a target market, subscribers served by these
temporary connections will be migrated to RCN's advanced fiber optic network.
Within a building (or small grouping of buildings) a voice service hub is
established by installing an Integrated Digital Loop Carrier ("IDLC") device,
which acts as the point of interface between the SONET backbone facility and the
intra-building wiring. Each IDLC is installed with a standby power system and is
capable of serving up to 672 lines. The IDLC is capable of supporting a wide
range of both non-switched services (DS-1, digital data) and switched voice
services and features including ISDN, Custom Calling and CLASS features. Within
each building, internal wiring (twisted pair copper cable) connects the IDLC to
the customer premises and the customer-owned telephone equipment. In certain
instances, voice service is extended to other buildings in the building group or
cluster via either fiber optic cable or twisted pair copper cable. At the time
of initial wiring, RCN generally installs wiring in excess of its initial
requirements, in order to meet future subscriber demand.

     Video Programming

     Advanced Fiber Optic Networks. There are presently two video headend
locations within RCN's advanced fiber optic networks in New York City and
Boston. The video headends consist of optical transmitters, optical receivers,
satellite receivers, signal processors, modulators, encoding equipment and
network status monitoring and automated tape distribution equipment. From the
headend, the video signal is distributed to individual fiber nodes or receivers
via the same fiber cable backbone used to deliver the voice and data service.
The fiber cable terminates in a fiber optic receiver within an individual
building or service area. From the fiber node, coaxial cable and related
distribution equipment is used to distribute the video signals to the customer
premises. The bandwidth of the video distribution is a minimum of 750 MHZ, which
is capable of supporting a minimum of 110 video channels. This distribution
plant is specifically designed to be predominantly fiber-based, which increases
the reliability and improves the quality of the services delivered compared to
traditional cable television distribution architectures.

     Wireless Video. RCN also owns and operates a "wireless video" television
system (which was formerly operated as Liberty Cable Television of New York, the
operations of which were acquired by RCN in 1996) using point-to-point 18GHz
microwave technology. RCN is utilizing this system in New York City as an
alternate platform for delivering television programming to buildings that are
not yet connected to the advanced fiber optic network. RCN expects that the
majority of the buildings currently served by the wireless service will
ultimately be connected to the network, to the extent that connection is
feasible. As buildings are connected to the RCN network, RCN will reuse the
microwave equipment to provide service to other customers in off-network
premises. The transmission equipment and microwave services used to provide
RCN's wireless service are provided by Bartholdi Cable, which formerly operated
Liberty Cable Television of New York. Bartholdi Cable has agreed to provide
transmission services to RCN until RCN has either converted the subscribers to
its advanced fiber optic network or has obtained FCC authority to provide such
services pursuant to its own licenses. In addition, Bartholdi Cable has agreed
to transfer to RCN the transmission equipment on demand. Bartholdi Cable's
obligation to provide transmission services is subject to Bartholdi Cable having
authority to provide such services. The qualifications of Bartholdi Cable to
hold certain of the licenses needed to provide transmission services to RCN are
at issue in an FCC proceeding in which an Initial Decision was released on March
6, 1998. In the Initial Decision, the Administrative Law Judge found Bartholdi
Cable unqualified with respect to 15 such licenses. The Initial Decision will
become effective 50 days after its release unless Bartholdi Cable, as expected,
files exceptions to the Initial Decision within 30 days of its release or the
FCC elects to review the case on its own motion. Because of the uncertainty as
to Bartholdi Cable's right in the future to offer transmission services to RCN,
the Company filed its own license applications at the FCC for all of the
microwave transmission paths which are currently being used by Bartholdi Cable
to provide transmission services to RCN and, in light of the increased
uncertainties resulting from the Initial Decision in the FCC proceeding
involving certain of Bartholdi Cable's licenses, the Company expcets now
actively to pursue its license applications. There can be no assurance that RCN
will be able to obtain its own FCC license.

     Hybrid Fiber/Coaxial Cable Systems. RCN owns and operates hybrid
fiber/coaxial cable television networks in Pennsylvania, New Jersey and New York
State (outside of New York City), all within 75 miles of New York City. These
networks offer expanded bandwidth and a platform for two-way services, and have
an aggregate of 658 route miles of fiber optic cable, including separate high
capacity fiber optic rings with a minimum 84 fibers in Pennsylvania (covering
approximately 69 route miles) designed and constructed as competitive telephony
networks. The New York system includes 211 route miles of fiber optic cable
serving 98 nodes from one head-end. Approximately 70% of the New York system is
two-way active 750 MHZ plant with 84 active channels of programming. The New
Jersey system has deployed 144 route miles of fiber optic cable (over 30 miles
of which is two-way active) from two head-ends, and generally operates a 400/450
MHZ plant providing 62 channels of video programming. The Pennsylvania system
operates 2,649 miles of coaxial cable and over 234 route miles of fiber with 43
nodes from one headend, operating at 550 MHZ with 84 active channels. All of the
Company's hybrid fiber/coaxial cable systems are 100% one-way addressable.

     These fiber-rich networks provide a basic fiber optic platform capable of
enhancement for supporting two-way services, such as high-speed Internet
services, in the future. RCN is presently expanding the fiber capacity of
certain of these fiber/coaxial cable television networks so that they will be
capable of delivering switched two-way services in the future. In August 1997,
RCN commenced offering resold local phone service, long distance and Internet
access to customers in the area served by its Hybrid Fiber/Coaxial Cable Systems
in Pennsylvania.

     Data Services

     RCN's Internet access and data transmission services are currently provided
over the advanced fiber optic network via dial-up modems facilitated through the
RCN voice network in on-net subscriber applications. In off-net situations,
subscribers use conventional dial-up modems through the incumbent LEC network to
access RCN's Internet transmission network. RCN is beginning to offer Internet
and data transmission services via cable modems. Cable modems, which utilize the
broadband coaxial plant, offer higher speed access for data transmission than
the speeds achieved by conventional telephone dial-up technology.

     Erols provides high quality Internet access services to businesses by
utilizing high-speed access via ISDN, frame relay, fractional T-1, T-1 and T-3
circuits. Erols' network infrastructure currently supports modems with
dial-access speeds of up to 56 Kbps. Erols provides new dial-access subscribers
with its easy-to-install proprietary access software package, which incorporates
a telephone dialer, an e-mail platform, a Web browser (either Netscape
Communication Corporation's ("Netscape") Navigator (a registered trademark of
Netscape) or Microsoft Corp.'s Microsoft(R) Internet Explorer) and SurfWatchTM
software for parental control over Internet content access. This software
package permits simplified access to the Internet through a "point and click"
graphical user interface. After installation, the subscriber has a direct
connection to the Internet using Point-to-Point Protocol and access to all of
the Internet's resources, including e-mail, the World Wide Web, Usenet News
service and Internet Relay Chat. Access software automatically displays the
Erols World Wide Web site each time a subscriber logs on, providing Erols with
the opportunity to communicate with its subscribers at the start of each
session. Erols maintains "24 x 7" subscriber and technical support 365 days a
year.

     Ultranet utilizes K56Flex protocol to support its POPs, a result of a major
mid-1997 upgrade in Ultranet transmission equipment. This advancement has
empowered users to gain access to two to four times more quickly to equipment
that is also more reliable. The new infrastructure takes advantage of Rockwell
technology that supports the K56Flex modems (speeds up to 56 Kbps) and ISDN
(speeds up to 128 Kbps). By connecting users to the Internet faster, downloading
time is decreased, and in turn, telephone costs and time online.

     RCN intends to extend its network to cover most of the areas currently
served by Erols and Ultranet and ultimately to migrate most of those customers
to RCN's advanced fiber optic network, subject to certain regulatory approvals
and the approval of RCN's joint venture partners.

Hybrid Fiber/Coaxial Cable Systems

     RCN's hybrid fiber/coaxial cable systems were operated by C-TEC prior to
the Distribution. The following table summarizes the development of the hybrid
fiber/coaxial cable systems over the last five years:

</TABLE>
- -------------------

(1)  Decline in basic penetration levels and average monthly revenue per
     subscriber in 1995 reflects the acquisition of the Pennsylvania cable
     systems, which are in a market in which a competing franchisee also offers
     service. 

     The service areas for these cable television networks enjoy favorable
customer demographics. The New York and New Jersey systems primarily serve
affluent bedroom communities in suburban New York City, with 28,411 and 76,127
connections at December 31, 1997 respectively. The system in New York State
serves ten municipalities in Duchess, Putnam and Westchester Counties,
approximately 45 miles north of New York City. The New Jersey system serves 31
contiguous municipalities in Hunterdon, Mercer, Morris and Somerset Counties,
approximately 50 miles west of Manhattan. The Pennsylvania system, which is the
largest competitive cable television system in the United States, serves
Pennsylvania's Lehigh Valley area including the cities of Allentown, Bethlehem
and Easton, and virtually all of Lehigh and Northampton Counties, and is located
less than 10 miles west of the Company's New Jersey system.

Interconnection

     Because access to the public switched telephone network is an essential
component of any regional or national telecommunications network,
interconnection is critical to RCN's ability to provide voice and data services.
Bell Atlantic and the other incumbent LECs and independent telephone companies
are required to provide interconnection to CLECs such as RCN pursuant to the
facilities-based interconnection requirements of Section 251 of the 1996 Act.
Under the 1996 Act, the RBOC's ability to offer inter-LATA long distance service
is contingent upon their ability to create an environment allowing
economically-efficient competition in their local markets for both business and
residential services.

     RCN has achieved interconnection through comprehensive telephone service
co-carrier interconnection agreements with Bell Atlantic and Sprint-New Jersey
covering their service areas in ten states and the District of Columbia in the
Northeast and New England-Middle Atlantic corridor areas. These agreements will
remain in effect regardless of the outcome of the proceedings regarding the
FCC's Section 251 regulations. RCN's interconnection agreements with Bell
Atlantic cover its service areas in the states of Massachusetts, New York,
Vermont, New Hampshire, Maine, Rhode Island, Delaware, Maryland, New Jersey,
Pennsylvania and Virginia and the District of Columbia. The agreement with
Sprint-New Jersey covers its service area in the State of New Jersey. All of
these agreements have been approved by the state regulatory commissions pursuant
to Section 252 of the Communications Act of 1934, as amended by the
Telecommunications Act of 1996 (the "Communications Act"). RCN believes it has
more interconnection agreements with incumbent LECs than any other company
focused primarily on the residential telecommunications market.

     The terms of RCN's interconnection agreements with the incumbent LECs
include the following provisions: (i) interconnection at any technically
feasible point within their networks, equal in quality to what the incumbent LEC
provides to itself or to affiliates, (ii) exchange of all local traffic at a
fully reciprocal and identical rate; (iii) receipt by RCN of access charges for
long distance calls made to and from its customers, including full "pass
through" to RCN of such compensation on number portability; (iv) interim number
portability arrangements to allow customers to keep their telephone numbers when
they switch carriers; (v) unbundled network elements, including local loop
transmission from the incumbent LEC's central offices to the customer's premises
distinct from local switching or other services; (vi) nondiscriminatory access
to 911 and emergency 911 services; directory assistance services to allow RCN's
customers to obtain telephone numbers; operator call completion services and
white pages directory listings for RCN's customers; and (vii) access to the
poles, ducts, conduits and rights-of-way owned or controlled by the incumbent
LEC at nondiscriminatory rates. The interconnection agreements generally have an
initial term of three years and are cancellable thereafter at 90 days' notice.

Resale Arrangements

     Resale of Bell Atlantic Local Telephone Services

     RCN provides local telephone service on a resale basis to customers not
connected to the advanced fiber optic facilities. As of December 31, 1997 RCN
had 24,900 customers for local telephone services provided through agreements to
act as a reseller of Bell Atlantic local telephone services. RCN offers its
resale customers competitive telephone rates and RCN's superior customer
service. Resale customers are billed by RCN and RCN personnel provision customer
service requests by coordinating with the incumbent LECs on the customers'
behalf.

     RCN has entered into agreements to act as a reseller of Bell Atlantic local
telephone services, which enable RCN to grow its subscriber base by offering
telephone services in advance of connecting the customers to an advanced fiber
optic network. RCN's agreements with Bell Atlantic allow RCN to purchase at a
"wholesale" discount (the amount of which is determined by regulatory
commissions in each state) any telephone services that those companies offer to
their end users, such as local exchange services, vertical features including
Caller ID, Call Waiting, etc., and regional toll calls. The agreements provide
that RCN will be entitled to the most favorable terms and conditions, including
wholesale discounts, available to any telecommunications carrier reselling
similar services.

     Long Distance Resale

     RCN Commercial provides long distance telephone services, including private
line, operator and calling card services, to residential and business customers
throughout the United States. Such services are provided through an owned and
leased switching network utilizing leased interconnection facilities and long
distance resale. RCN provides on network origination and termination of long
distance telephone services throughout the Mid-Atlantic and New England states.
For call origination and completion throughout the rest of the country, RCN has
various resale agreements. Specifically, RCN has contracted with LCI for 800/888
origination, Frontier for off network origination of outbound calling and
various carriers for terminating calls.

     DirecTV

     In October 1996, RCN signed an agreement with DirecTV to deliver DirecTV's
high-power direct broadcast satellite service to MDUs in New York City. DirecTV
allows RCN to offer an additional 175 channels of programming including
exclusive sports programming.

Marketing

     RCN Telecom Services

     RCN focuses its marketing efforts on residential customers in high-density
areas, with an initial focus on residential customers located on or near RCN's
current or proposed advanced fiber optic networks. Through these advanced fiber
optic networks, RCN is able to offer a wide range of telecommunication services,
including bundled service options, and to offer its services at rates that are
competitive with the incumbent LECs and cable television operators and the major
IXCs. RCN believes that quality of service, superior technology and the ability
to offer bundled services, as well as price, will be more important to its
customers than brand-name recognition. Although RCN's initial marketing focus
has been on residential customers, it also will seek to provide communications
services to commercial customers located on its advanced fiber optic networks
wherever feasible, particularly with respect to small and medium size businesses
in Boston and in other areas outside of New York City, including new markets.
RCN will also market its advanced fiber-based services to institutional
accounts, such as hotels, universities and hospitals.

     RCN has a team of direct sales personnel calling on targeted customers.
This team has salespeople dedicated to selling commercial accounts and
salespeople dedicated to selling to residential households. This is done with a
combination of lead follow-up and cold calling. Prospective commercial customers
are typically offered local and long distance voice services, with options for
video and data service as well. Prospective residential customers are solicited
as the fiber network is activated at the customer location and the complete
array of RCN services is offered, with the choice of a discounted bundled
package or individual service selections.

     RCN markets its telephone services both as separate customer options for
local voice, long distance, video, and data access, and as a bundled discounted
package from a single service provider. RCN advertises its services and
availability through television, radio and newspapers, as well as on bus
shelters, subway stations, billboards, and other local outlets, and recently
launched a mass-media advertising campaign in New York City and Boston. Customer
response is generally channeled to 1-800-RING-RCN or www.rcn.com. Advertising is
supported via targeted direct mail and telemarketing. Customers are offered
special incentives to purchase more than one service from RCN. For example, as a
six-month introductory offer, New York City customers purchasing both video and
local voice service are currently eligible for a basic cable rate reductions.

     RCN has employed specific teams dedicated to offering service to customers
in MDUs in high-density metropolitan areas. First, an access agreement team
makes presentations to owners/managers of MDUs seeking to obtain private access
agreements. This team also assists with presentations to municipal officials in
connection with applications for OVS license agreements and franchise
agreements. As of December 31, 1997 RCN had obtained 654 access agreements
covering over 125,987 units in MDUs in New York City and Boston and surrounding
communities (markets of 2.9 million households and 770,000 households,
respectively). Access agreements permit the installation of electronics and
wiring to service the buildings and typically provide a term of access of 5-10
years. Of RCN's current access agreements, 5% expire within the next three
years, 22% expire in 3-5 years and 73% expire thereafter. The access agreements
generally provide for non-exclusive access, but for exclusive marketing
assistance, whereby the building management promotes and assists in the
promotion of RCN's services on an exclusive basis. As an incentive, RCN may
negotiate a success-based marketing payment to the building owner. This payment
takes the form of either a percentage of revenue, or a reduced rate for
services. RCN has also employed bulk service agreements pursuant to which RCN
provides services (generally video services) at a flat subscription rate
covering all units in the residential building (typically, a condominium or
cooperative apartment building) or institution. RCN believes that bulk sales
contracts are a useful vehicle for early entry into a market, but expects the
majority of its future agreements to facilitate the purchase of services on an
individual basis.

     Second, a sales team, led by a group of customer account managers, seeks to
solidify the relationships with the building owners/management, by coordinating
the installation process, organizing the initial marketing and promotion at each
building, and selling RCN services to each building resident. Usually, after an
announcement and informational package is distributed to each building resident,
a lobby demonstration and enrollment event takes place over several evenings.
Residents are offered free installation and convenient appointments. After the
initial sales and installation process is completed, the customer account
manager works with the building owner/manager to maximize ongoing penetration,
especially through the signup of new move-in residents.

     RCN has opened two high-tech visitor centers in prominent locations in
Boston and New York City, where potential customers can sample RCN's services. A
network operations center including a graphic representation of the RCN network
is on view at each location.

     Hybrid Fiber/Coaxial Cable Television

     Sales and marketing to customers served by the Company's hybrid
fiber/coaxial cable systems is accomplished through a variety of means including
door-to-door sales, direct mail, telemarketing, incentive programs and print and
broadcast advertising. In addition to marketing efforts targeting new
subscribers, the Company conducts periodic campaigns to encourage existing
customers to purchase higher levels of service.

Customer Service and Billing

     RCN has implemented a flexible, customer-service oriented approach which
RCN believes differentiates it from the mass-market strategy of the incumbent
providers. RCN provides customer service 24 hours a day, seven days a week from
established central call centers. The facilities utilize state of the art
technology which allows communication with subscribers, field technicians and
the Company's field offices. The largest of these facilities is located in
Dallas, Pennsylvania and handles the majority of the customer service calls. In
1997, approximately 90% of calls placed to the facility in Dallas, Pennsylvania
were answered in 30 seconds or less. Additionally, the facility in Dallas,
Pennsylvania initiates 540 technician service routes per day. The technical
staff consistently maintains an on-time appointment percentage of 99.8%. In
order to maximize efficiency, all service trucks are equipped with two-way
radios and supervisors' trucks are equipped with cellular phones. RCN's customer
service professionals, installers and technicians have been professionally
trained, and many of the service technicians are trained to handle both voice
and video service. RCN believes that its infrastructure for billing and customer
service will provide a competitive advantage in expanding into new markets.

     RCN's advanced fiber optic network is continuously monitored for quality
control and capacity issues, pursuant to a control system featuring 16 alarm
monitor points per hub site and automated housekeeping alarms.

     Billing services for video are provided by CableData while RCN telephony
billing services are provided by Consolidated Communications Systems and
Services. At the present time, RCN customers receive separate billing statements
for video and telephone service although RCN intends to offer a single billing
option in the future.

     Account piracy is monitored by ongoing field audits and, in RCN's advanced
fiber optic networks, through use of state of the art scrambling systems.
Potential new customers are generally screened for credit history before being
authorized for service. RCN employs a full-time credit and collection staff as
well as a group that seeks to minimize toll fraud by detecting and monitoring
suspicious calling patterns.

Programming and Suppliers

     RCN has secured license arrangements with all of its desired programming
suppliers, some of which provide volume discount pricing structures and/or offer
marketing support to the Company. Many of these arrangements are extensions of
long-standing agreements entered into by or on behalf of the Company's hybrid
fiber/coaxial cable systems, and some are newly negotiated based upon RCN's OVS
certifications. RCN has generally obtained these license arrangements on terms
and conditions that it considers favorable.

     RCN programming arrangements include arrangements for basic video channels,
premium channels including multi-plexing, pay-per-view movies and events, adult
entertainment, electronic program guide services and digital music services, as
well as retransmission arrangements for relevant network broadcasters.

     The Company generally pays a monthly fee per subscriber per channel for
programming purchased from its suppliers. Programming costs increase in the
ordinary course of the Company's business as a result of increases in the number
of subscribers, expansion of the number of channels provided to customers and
contractual rate increases from programming suppliers. The Company anticipates
that future contract renewals for video providers such as the Company will
result in programming costs exceeding current levels, particularly for sports
programming.

     A wide range of national manufacturers are the primary sources of supplies,
equipment and materials utilized in the development and enhancement of the
Company's networks. RCN has entered into Master Purchase Agreements with certain
equipment suppliers which enable it to purchase video and switching equipment on
terms which it considers favorable. The Company anticipates that the costs for
these supplies, equipment and materials will be significant in future periods.
The amount of such costs will depend on numerous factors, many of which are
beyond the Company's control.

RCN Commercial

     RCN Commercial, a division of RCN's wholly owned subsidiary RCN Long
Distance Company, provides switched-based resale long distance services to
customers on the advanced fiber optic network as well as other customers. RCN
Commercial operates the long distance business formerly operated by C-TEC,
except within the Commonwealth Service Territory. During 1996, RCN obtained
certification in forty-seven states. RCN Commercial also provides local
telephone service to commercial customers. As of December 31, 1997 Commercial
had approximately 13,595 long distance customers.

International

     The Company owns a 40% interest in Megacable, the second largest cable
television provider in Mexico. Megacable owns 22 wireline cable systems, and one
MMDS cable system, in Mexico, principally on the Pacific and Gulf coasts and
including Guadalajara, the second largest city in Mexico, Hermosillo, the
largest city in the state of Sonora and Veracruz, the largest city in the state
of Veracruz. At December 31, 1997 their wireline systems passed approximately
635,350 homes and served approximately 209,300 subscribers. Megacable had
revenues of $30.4 million and $23.2 million for the years ended December 31,
1997 and 1996, respectively. Recent financial results for Megacable expressed on
a U.S. GAAP basis and subscriber data are summarized below:

     new services to customers, to further improve the quality of service and to
     fund new investment opportunities.

(3) Includes 2,325 MMDS subsidiaries in Juarez, Mexico.

     Megacable is presently expanding the fiber capacity of certain of its
systems to provide high-speed data services and potentially voice services.
Specifically, Megacable has built out its systems in Veracruz, Jalapa, Tepic and
certain neighborhoods in Guadalajara using hybrid fiber/coaxial network
architecture, to provide a fiber optic cable "backbone" capable of providing
these services.

     Additionally, Megacable presently holds a 99% interest in Megacable
Comunicaciones de Mexico S.A. ("MCM"). MCM has received a license from the
Mexican government to allow it to build a fiber optic network in Mexico City,
Monterrey and Guadalajara. MCM intends to use this network to provide local
voice and high-speed data service in these cities, principally to commercial
customers in Mexico City.

Competition

     Overview

     RCN competes with a wide range of service providers for each of the
services that it provides. Virtually all markets for voice and video services
are extremely competitive, and RCN expects that competition will intensify in
the future. In each of the markets in which it offers voice and video
programming services, RCN faces significant competition often from larger,
better-financed incumbent local telephone carriers and cable companies, and RCN
often competes directly with incumbent providers which have historically
dominated their respective local telephone and cable television markets. These
incumbents presently have numerous advantages as a result of their historic
monopoly control of their respective markets. However, RCN believes that most
existing and potential competitors will, at least initially, provide narrower
service offerings over limited delivery platforms as compared to the wide range
of voice, video and data services that will be provided over RCN's fiber-based
networks, thereby providing RCN with an opportunity to achieve important market
penetration.

     With respect to local telephone services, RCN competes with the incumbent
LECs, and alternative service providers including CLECs. Commercial mobile radio
services providers, including cellular carriers (such as Bell Atlantic Mobile
Services), personal communications services ("PCS") carriers (such as Sprint
Spectrum), and enhanced specialized mobile radio services ("ESMRS") providers
(such as NexTel), may also become a source of competitive local and long
distance telephone service. However, RCN believes these operators may primarily
use competitive access services to transport their calls among their radio
transmitter/receiver sites through networks that avoid the incumbent LECs with
whom they compete.

     With respect to long distance telephone services, RCN faces, and expects to
continue to face, significant competition from the IXCs, including AT&T, Sprint
and MCI, which account for the majority of all long distance revenue. The major
long distance service providers benefit from established market share and from
established trade names brought about by nationwide advertising. RCN, however,
regards its long-distance service as a complementary service rather than a
principal source of revenue. Certain IXCs, including AT&T, MCI and Sprint, have
also announced their intention to offer local services in major U.S. markets
using their existing infrastructure in combination with resale of incumbent LEC
service, lease of unbundled local loops or other providers' services.

     All of the Company's video services face competition from alternative
methods of receiving and distributing television signals and from other sources
of news, information and entertainment such as off-air television broadcast
programming, newspapers, movie theaters, live sporting events, interactive
online computer services and home video products, including videotape cassette
recorders. Among the alternative video distribution technologies are home
satellite dish earth stations ("HSDs") which enable individual households to
receive many of the satellite-delivered program services formerly available only
to cable subscribers. Furthermore, the 1992 Act contains provisions, which the
FCC has implemented with regulations, to enhance the ability of cable
competitors to purchase and make available to HSD owners certain
satellite-delivered cable programming at competitive costs. RCN faces additional
competition from private satellite master antenna television ("SMATV") systems
that serve condominiums, apartment and office complexes and private residential
developments. The FCC and Congress have adopted policies providing a more
favorable operating environment for new and existing technologies that provide,
or have the potential to provide, substantial competition to the Company's
various video distribution systems. These technologies include, among others,
DBS service whereby signals are transmitted by satellite to receiving facilities
located on customer premises. The Company expects that its video programming
services will face growing competition from current and new DBS service
providers. RCN also competes with wireless program distribution services such as
multi-channel multipoint distribution service ("MMDS") which use low-power
microwave frequencies to transmit video programming over-the-air to subscribers.
The Company is unable to predict whether wireless video services will have a
material impact on its operations.

     Other new technologies, including Internet-based services, may become
competitive with services that RCN can offer. Advances in communications
technology as well as changes in the marketplace and the regulatory and
legislative environment are constantly occurring. Thus, it is not possible to
predict the effect that ongoing or future developments might have on the video
industry or on the operations of the Company.

     RCN believes that among the existing competitors, the incumbent LECs,
incumbent cable providers and the CLECs provide the most direct competition to
RCN in the delivery of "last mile" connections for voice and video services.

     Incumbent LECs

     In each of its target markets for advanced fiber optic networks, RCN faces,
and expects to continue to face, significant competition from the incumbent LECs
(including Bell Atlantic in New York City and Boston), which currently dominate
their local telephone markets. RCN competes with the incumbent LECs in its
markets for local exchange services on the basis of product offerings (including
the ability to offer bundled voice and video services), reliability,
state-of-the-art technology and superior customer service, as well as price. RCN
believes that its advanced fiber optic networks provide superior technology for
delivering high-speed, high-capacity voice, video and data services as compared
to the primarily copper wire based networks of the incumbent LECs. However, the
incumbent LECs have begun to expand the amount of fiber facilities in their
networks and to prepare to re-enter the long distance telephone service market
and, in addition, have long-standing relationships with their customers.

     In addition, under the 1996 Act, and ensuing federal and state regulatory
initiatives, barriers to local exchange competition are being removed. The
introduction of such competition, however, also establishes the predicate for
the incumbent RBOCs, such as Bell Atlantic, to provide in-region interexchange
long distance services. The incumbent RBOCs are currently allowed to offer
"incidental" long distance service in-region and to offer out-of-region long
distance service. Once the incumbent RBOCs are allowed to offer in-region long
distance services, they will also be in a position to offer single source local
and long distance service similar to that offered by RCN and proposed by the
three largest IXCs (AT&T, MCI and Sprint). The Company expects that the
increased competition made possible by regulatory reform will result in certain
pricing and margin pressures in the telecommunications services business.

     RCN has sought, and will continue to seek, to provide a full range of local
voice services in competition with incumbent LECs in its service areas. The
Company expects that competition for local telephone services will be based
primarily on quality, capacity and reliability of network facilities, customer
service, response to customer needs, service features and price, and will not be
based on any proprietary technology. As a result of the comparatively recent
installation of RCN's advanced fiber optic networks, its dual path architecture
and the state-of-the-art technology used in its networks, RCN may have capital
cost and service quality advantages over some currently available local networks
relied upon by the incumbent LECs, as well as the competitive advantage provided
by the ability to deliver a bundled voice and video service.

     The 1996 Act permits the incumbent LECs and others to provide a wide
variety of video services directly to subscribers in competition with RCN.
Various LECs currently are providing video services within and outside their
telephone service areas through a variety of distribution methods, including
both the deployment of broadband wire facilities and the use of wireless
transmission facilities. The Company cannot predict the likelihood of success of
video service ventures by LECs or the impact on the Company of such competitive
ventures.

     Incumbent Cable Television Service Providers

     Certain of RCN's video service businesses compete with incumbent wireline
cable companies in their respective service areas. In particular, RCN's advanced
fiber optic networks compete for cable subscribers with the major wireline cable
operators in New York City and Boston, primarily Time-Warner Cable in New York
City and Cablevision in Boston. RCN's wireless video service in New York City
competes primarily with Time-Warner Cable. RCN believes that the expanded
capacity and fiber-to-node architecture of its advanced fiber optic networks in
New York City and Boston make it better equipped to provide high-capacity
communications services than coaxial cable based networks utilizing "tree and
branch" architecture. RCN's Pennsylvania hybrid fiber/coaxial cable television
system competes with an alternate service provider, Service Electric, which also
holds a franchise for the relevant service area.

     Since cable television systems generally operate pursuant to franchises
granted on a non-exclusive basis, and the 1992 Act prohibits franchising
authorities from unreasonably denying requests for additional franchises and
permits franchising authorities to operate cable systems, well-financed
businesses from outside the cable industry (such as the public utilities that
own certain of the poles on which cable is attached) may become competitors for
franchises or providers of competing services.

     CLECs and Other Competitors

     RCN also faces, and expects to continue to face, competition from other
potential competitors in certain of the markets in which RCN offers its
services. Other CLECs such as Teleport Communications Group, compete for local
telephone services, although they have to date focused primarily on the market
for commercial customers rather than residential customers. In addition,
potential competitors capable of offering private line and special access
services also include other smaller long distance carriers, cable television
companies, electric utilities, microwave carriers, wireless telephone system
operators and private networks built by large end-users, including Winstar,
Dualstar and New Vision. However, RCN believes that, at least initially, it is
relatively unique in its markets in offering bundled voice, video and data
services to customers in residential areas, and in striving to connect
residential customers directly to its advanced fiber optic network.

     Internet Services

     The market for Internet access services is extremely competitive and highly
fragmented. No significant barriers to entry exist, and accordingly competition
in this market is expected to intensify. The Company competes (or in the future
may compete) directly or indirectly with (i) national and regional ISPs; (ii)
established online services; (iii) computer software and technology companies;
(iv) national telecommunications companies; (v) LECs; (vi) cable operators; and
(vii) nonprofit or educational ISPs, and some of these present or potential
future competitors have or can be expected to have substantially greater market
presence and financial, technical, marketing and other resources than the
Company. Certain of the Company's online competitors, including America Online,
the Microsoft Network and Prodigy, have introduced unlimited access to the
Internet and their proprietary content at flat rates, and certain of the LECs
have also introduced competitive flat-rate pricing for unlimited access (without
a set-up fee for at least some period of time). Bell Atlantic has recently filed
with the Federal Communications Commission (the "FCC") a petition for an
exemption from a regulation prohibiting it from building a high-speed network.
Bell Atlantic's petition requests that such network, which would serve as an
Internet backbone, not be subject to pricing and other regulatory restriction.
The network would span the states from Maine to Virginia. There can be no
assurance that competition will not lead to pricing pressures in the Internet
business. For additional information on the competitive environment in which the
Company operates, see "Business--Competition."

     Other new technologies may become competitive with services that RCN can
offer. Cellularvision, a provider of LMDS, recently began offering wireless
Internet and video programming services in New York City and has announced plans
to offer telephone service in the future. Advances in communications technology
as well as changes in the marketplace and the regulatory and legislative
environment are constantly occurring. In addition, a continuing trend toward
business combinations and alliances in the telecommunications industry may also
create significant new competitors to RCN. The Company cannot predict whether
competition from such developing and future technologies or from such future
competitors will have a material impact on its operations.

Regulation

     The telephone and video programming transmission services offered by the
Company are subject to federal, state and local government regulation. The 1996
Act, which became effective in February 1996, introduced widespread changes in
the regulation of the communications industry, including the local telephone,
long distance telephone, data services, and television entertainment segments in
which the Company operates. The 1996 Act was intended to promote competition and
decrease regulation of these segments of the industry. The law delegates to both
the FCC and the states broad regulatory and administrative authority to
implement the 1996 Act.

     Telecommunications Act of 1996

     The 1996 Act eliminates many of the pre-existing legal barriers to
competition in the telephone and video programming communications businesses,
preempts many of the state barriers to local telephone service competition that
previously existed in state and local laws and regulations, and sets basic
standards for relationships between telecommunications providers.

     Among other things, the 1996 Act removes barriers to entry in the local
exchange telephone market by preempting state and local laws that restrict
competition and by requiring LECs to provide nondiscriminatory access and
interconnection to potential competitors, such as cable operators, wireless
telecommunications providers, and long distance companies. In addition, the 1996
Act provides relief from the earnings restrictions and price controls that have
governed the local telephone business for many years. The 1996 Act will also,
once certain thresholds are met, allow incumbent RBOCs to enter the long
distance market within their own local service regions.

     Regulations promulgated by the FCC under the 1996 Act require LECs to open
their telephone networks to competition by providing competitors
interconnection, access to unbundled network elements and retail services at
wholesale rates. As a result of these changes, companies such as RCN are now
able to interconnect with the incumbent LECs in order to provide local exchange
services. Numerous parties appealed certain aspects of these regulations, and
the appeals were consolidated in the United States Court of Appeals for the
Eighth Circuit. On July 18, 1997, the Eighth Circuit found constitutional
challenges to certain practices implementing cost provisions of the
Telecommunications Act that were ordered by certain state PUCs to be premature;
vacated significant portions of the FCC's nationwide pricing rules; and confined
the use of combined unbundled network elements to instances where the requesting
carrier itself would do the combining. On October 14, 1997, the Eighth Circuit
issued a decision vacating additional FCC rules that will likely have the effect
of increasing the cost of obtaining the use of combinations of an ILEC's
unbundled network elements. On January 26, 1998, the Supreme Court granted a
writ of certiorari under which it will review the July 18 Eighth Circuit
decision; it is expected (but not yet certain) that the Court will hear
arguments on this case in the fall of 1998. The Eighth Circuit decisions create
uncertainty about the rules governing pricing and terms and conditions of
interconnection agreements, and could make negotiating and enforcing such
agreements more difficult and protracted and may require renegotiation of
existing agreements. Prior to the Eighth Circuit decisions, the Company had
entered into interconnection agreements with Bell Atlantic, covering all of its
target market area, that are generally consistent with the FCC guidelines, and
those agreements remain in effect notwithstanding the reversal of the FCC rules.
There can be no assurance, however, that the Company will be able to obtain or
enforce future interconnection agreements, or obtain renewal of existing
agreements, on terms acceptable to the Company.

     Certain Bell Operating Companies ("BOCs") have also raised constitutional
challenges to restrictions in the 1996 Act preventing BOCs from entering the
long distance market in their home region. On December 31, 1997, the U.S.
District Court for the Northern District of Texas issued the SBC Decision
finding that Sections 271 to 275 of the 1996 Act are unconstitutional. SBC
Communications, Inc., et al. v. Federal Communications Commission, et al., Civil
Action No. 7:97-CV-163-X. These sections of the Act impose restrictions on the
lines of business in which the RBOCs may engage, including establishing the
conditions they must satisfy before they may provide in-region interLATA
telecommunications services. The District Court has stayed the SBC Decision
pending appeal. If the stay is lifted, the RBOCs (including Bell Atlantic, which
was permitted to intervene in the case) would be able to provide interLATA
services immediately without satisfying the statutory conditions. Although the
Company believes the factual assumptions and legal reasoning in the SBC Decision
are erroneous and therefore the decision will likely be reversed on appeal,
there can be no assurance of this outcome. If the SBC Decision were upheld on
appeal it may have an unfavorable effect on the Company's business for at least
two reasons. First, RBOCs currently have an incentive to foster competition
within their service areas so that they can qualify to offer interLATA services.
The SBC Decision removes this incentive by allowing RBOCs to offer interLATA
service without regard to their progress in opening their local markets to
competition. However, the SBC Decision would not affect other provisions of the
Act which create legal obligations for all ILECs to offer interconnection and
network access, and therefore will not impair the Company's ability to compete
in local exchange markets. Second, the Company is legally able to offer its
customers both long distance and local exchange services, which the RBOCs
currently may not do. This ability to offer "one-stop shopping" gives the
Company a marketing advantage that it would no longer enjoy if the SBC Decision
were upheld on appeal. The Company cannot predict either the outcome of these or
future challenges to the 1996 Act, any related appeal of regulation or court
decision, or the eventual effect on its business or the industry in general.

     The 1996 Act also makes far-reaching changes in the regulation of the video
programming transmission services offered by RCN, including changes to the
regulations applicable to video operators, the elimination of restrictions on
telephone company entry into the video business, and the establishment of a new
OVS regulatory structure for telephone companies and others to offer such
services. Under the 1996 Act, local telephone companies, including both
incumbent LECs such as Bell Atlantic, and CLECs such as RCN, may provide service
as traditional cable television operators subject to municipal cable television
franchises, or they may opt to provide their programming over non-franchised
open video systems subject to certain conditions, including, but not limited to,
making available a portion of their channel capacity for use by unaffiliated
program distributors and satisfying certain other requirements, including
providing capacity for public, educational and government channels, and payment
of a gross receipts fee equivalent to the franchise fee paid by the incumbent
cable television operator. RCN is one of the first CLECs to provide television
programming over an advanced fiber optic network pursuant to the OVS regulations
implemented by the FCC under the 1996 Act. As discussed below, RCN is currently
providing OVS service in the City of Boston, in the City of New York and in a
number of communities surrounding Boston. Starpower is negotiating similar
agreements in Washington and surrounding communities.

     Regulation of Voice Services

     RCN's voice business is subject to regulation by the FCC at the federal
level with respect to interstate telephone services (i.e., those that originate
in one state and terminate in a different state). State regulatory commissions
have jurisdiction over intrastate communications (i.e., those that originate and
terminate in the same state).

     State Regulation of Intrastate Local and Long Distance Telephone Services.
RCN's intrastate telephone services in Boston, New York City, and the Lehigh
Valley are (and Starpower's similar services in the Washington area will be)
regulated by the public service commissions or comparable agencies of the
various states in which these services are offered. RCN subsidiaries have
received either permanent or interim authority to offer intrastate telephone
services, including local exchange service, in Massachusetts, New York,
Pennsylvania, Maryland, the District of Columbia, and Virginia (as well as in
some neighboring jurisdictions where the Company does not currently operate but
may expand in the future). Starpower has filed separately applications for
similar authority in Maryland, the District of Columbia, and Virginia.
Starpower's applications in Maryland and Virginia have been granted. RCN's
resale agreements with Bell Atlantic have been approved, pursuant to Section 252
of the Communications Act by state regulatory commissions in Delaware, the
District of Columbia, Maine, Maryland, Massachusetts, New York, New Jersey, New
Hampshire, Pennsylvania, Rhode Island, Vermont, and Virginia.

     RCN Long Distance Company is authorized to offer intrastate long distance
services in Pennsylvania, New York and Massachusetts and, in addition, has
received state regulatory authority to offer such services in 45 other states
nationwide. Pursuant to such authorizations, RCN Long Distance Company is
permitted to resell intrastate long distance services both to other carriers,
including RCN's local operating subsidiaries and Starpower for resale to their
end user subscribers, and to its own end user customers.

     FCC Regulation of Interstate and International Telephone Services. RCN,
through several of its subsidiaries, including RCN Long Distance Company, may
also provide domestic interstate telephone services nationwide pursuant to
tariffs on file at the FCC, and has been authorized by the FCC under Section 214
of the 1996 Act to offer worldwide international services as well. RCN is
authorized to resell in-state long-distance services in 48 states (all except
Alaska and Hawaii), and, where required, has registered with or obtained
licenses or certificates from state regulatory agencies for the provision of
this service.

     Local Regulation of Telephone Services. Municipalities also regulate
limited aspects of RCN's voice business by, for example, imposing various zoning
requirements and, in some instances, requiring telecommunications licenses,
franchise agreements and/or installation permits for access to local streets and
rights-of-way. In New York City, for example, RCN will be required to obtain a
telephone franchise in order to provide voice services using its advanced fiber
optic network facilities located in the streets of New York City (although
services may be provided over certain leased or resold facilities pending
receipt of a franchise).

     Regulation of Video Services

     Open Video Systems. In February 1997, RCN subsidiaries were certified to
operate OVS networks in the five boroughs of New York City and, as part of the
BECO joint venture, in Boston and 47 surrounding communities. Initiation of OVS
services is subject to completion of an open enrollment period for
non-affiliated video programmers to seek capacity on the systems and upon
negotiation of certain agreements with local governments. The initial open
enrollment period for both the New York City and Boston area systems has
expired. RCN executed an agreement with the City of Boston on June 2, 1997, and
initiated OVS service in the City on that day. Pursuant to its agreement with
the City of Boston, RCN will be required to pay a fee to the City equal to 5% of
video revenues. RCN has entered into similar OVS agreements or is in the process
of negotiating agreements with certain other Boston-area municipalities, either
to offer OVS services or franchised cable television services. RCN executed an
agreement with the City of New York on December 29, 1997, and has initiated OVS
service in the Borough of Manhattan pursuant to that agreement.

     In areas where it offers video programming services as an OVS operator, RCN
is required to hold a 90-day open enrollment period every three years, during
which times RCN will be required to offer capacity on its network to other VPPs.
Under the OVS regulations, RCN must offer at least two-thirds of its capacity to
unaffiliated parties, if demand for such capacity exists during the open
enrollment period. In certain areas, RCN is in discussions with local municipal
authorities to explore the feasibility of obtaining a cable franchise in lieu of
an OVS agreement, and will consider providing RCN video service pursuant to
franchise agreements rather than OVS certification, if franchise agreements can
be obtained on terms and conditions acceptable to RCN. However, RCN will
consider the relative benefits of OVS certification versus local franchise
agreements, including the possible imposition of universal service requirements,
before making any such decisions. In addition, the current FCC rules concerning
OVS are subject to appeal in the United States Court of Appeals and, to the
extent that certain favorable aspects of the FCC's rules are overturned on
appeal, the determination of whether to operate as an OVS provider versus as a
franchised cable television operator may be affected. Moreover, the incumbent
cable television provider in Boston, Cablevision Systems, has requested that the
FCC permit it to obtain capacity on RCN's Boston area OVS network, and Time
Warner, the incumbent cable television provider in certain communities in the
Boston area, has made a similar filing at the FCC with respect to its request
for capacity on the Boston OVS network. RCN will continue to oppose these
requests, but to the extent that the FCC were to grant any such request(s), such
a result would likely affect the Company's determination as to whether to
operate as an OVS provider versus as a franchised cable television operator.

     Prior to its certification as an OVS provider, RCN offered limited video
programming services using the VDT services offered by MFS/WorldCom in Manhattan
and the City of Boston. In February 1997, the FCC held that MFS/WorldCom's
facilities did not qualify as video dialtone facilities entitled to an extension
of time to comply with the newly adopted OVS rules; nonetheless, the FCC did not
direct MFS/WorldCom and RCN to cease video programming distribution operations
over the MFS/WorldCom platform. One of the incumbent cable television companies
in New York City has filed a complaint with the New York Public Service
Commission challenging the former (pre-OVS) operations of RCN and WorldCom under
the VDT framework, which remains pending before that Commission.

     Wireless Video Services. RCN's 18 GHz wireless video services in New York
City are distributed using microwave facilities provided by Bartholdi Cable
pursuant to temporary authorizations issued to Bartholdi Cable by the FCC.
Bartholdi Cable has agreed to provide transmission services to RCN until RCN has
either converted the wireless video subscribers to its advanced fiber optic
network facilities or has obtained FCC authority to provide such services
pursuant to its own wireless radio licenses. In addition, Bartholdi Cable has
agreed to transfer to RCN the transmission equipment on demand. Bartholdi
Cable's obligation to provide transmission services is subject to Bartholdi
Cable having licenses from the FCC to provide such services. The qualifications
of Bartholdi Cable to hold certain of the licenses needed to provide
transmission services to RCN are at issue in an FCC proceeding in which an
Initial Decision was released on March 6, 1998. In the Initial Decision, the
Administrative Law Judge found Bartholdi Cable unqualified with respect to 15
such licenses. The Initial Decision will become effective 50 days after its
release unless Bartholdi Cable, as expected, files exceptions to the Initial
Decision within 30 days of its release or the FCC elects to review the case on
its own motion. Because of the uncertainty as to Bartholdi Cable's right in the
future to offer transmission services to RCN, the Company filed its own license
applications at the FCC for all of the microwave transmission paths which are
currently being used by Bartholdi Cable to provide transmission services to RCN
and, in light of the increased uncertainties resulting from the Initial Decsion
in the FCC proceeding invoving certain of Bartholdi Cable's licenses, the
Company expects now actively to pursue its license applications. While the
Company expects to receive authorizations to transmit over these microwave
paths, there can be no assurance that RCN will be able to offer wireless video
services pursuant to its own FCC licenses or that the FCC's investigation will
be resolved favorably. The failure to obtain such license or resolve such
proceedings would materially adversely affect the Company's wireless video
operations in New York City.

     There can be no assurance that RCN will be able to obtain or retain all
necessary authorizations needed to construct advanced fiber optic network
facilities, to convert its wireless video subscribers to an advanced fiber optic
network or to offer wireless video services pursuant to its own FCC licenses.

     Hybrid Fiber/Coaxial Cable. RCN's hybrid fiber/coaxial cable systems are
subject to regulation under the Cable Television Consumer Protection and
Competition Act of 1992, as amended (the "1992 Act"), which provides, among
other things, for rate regulation for cable services in communities that are not
subject to "effective competition," certain programming requirements, and
broadcast signal carriage requirements that allow local commercial television
broadcast stations to require a cable system to carry the station. Local
commercial television broadcast stations may elect once every three years to
require a cable system to carry the station ("must-carry"), subject to certain
exceptions, or to withhold consent and negotiate the terms of carriage
("retransmission consent"). A cable system generally is required to devote up to
one-third of its activated channel capacity for the carriage of local commercial
television stations whether pursuant to the mandatory carriage or retransmission
consent requirements of the 1992 Act. Local non-commercial television stations
are also given mandatory carriage rights. The FCC recently issued rules
establishing standards for digital television ("DTV"). Among other provisions,
the FCC's rules require television stations to simulcast their NTSC and DTV
signals for a period of years. During this simulcast period, it is unclear
whether must-carry rules will apply to DTV signals. The Communications Act
permits franchising authorities to require cable operators to set aside certain
channels for public, educational and governmental access programming. Cable
systems with 36 or more channels must designate a portion of their channel
capacity for commercial leased access by third parties to provide programming
that may compete with services offered by the cable operator.

     On September 8, 1997, the Company was notified by the FCC that it has ruled
that certain of the Company's upper levels of service for its New Jersey systems
are regulated levels of service and that the Company's rates for such levels of
service have exceeded the allowable rates under the FCC rate regulation rules
which have been effective since September 1993. The Company had treated these
levels of service as unregulated. The Company intends to contest this decision.
The Company does not believe that the ultimate resolution of this matter will
have a material impact on its results of operations or financial condition.

     Because a cable communications system uses local streets and rights-of-way,
such cable systems are generally subject to state and local regulation,
typically imposed through the franchising process. The terms and conditions of
state or local government franchises vary materially from jurisdiction to
jurisdiction and generally contain provisions governing cable service rates,
franchise fees, franchise term, system construction and maintenance obligations,
customer service standards, franchise renewal, sale or transfer of the
franchise, territory of the franchisee and use and occupancy of public streets
and types of cable services provided. Local franchising authorities (state or
local, depending on the practice in individual states) may award one or more
franchises within their jurisdictions and prohibit non-grandfathered cable
systems from operating without a franchise in such jurisdictions. The
Communications Act also provides that in granting or renewing franchises, local
authorities may establish requirements for cable-related facilities and
equipment, but not for video programming or information services other than in
broad categories. The Communications Act limits the payment of franchise fees to
5% of revenues derived from cable operations and permits the cable operator to
obtain modification of franchise requirements by the franchise authority or
judicial action if warranted by changed circumstances.

     RCN's ability to provide franchised cable television services is dependent
to a large extent on its ability to obtain and renew its franchise agreements
from local government authorities on generally acceptable terms. RCN currently
has 91 franchise agreements relating to the hybrid fiber/coaxial cable systems
in New York (outside New York City), New Jersey and Pennsylvania. These
franchises typically contain many conditions, such as time limitations on
commencement and completion of construction, conditions of service, including
the number of channels, the provision of free service to schools and certain
other public institutions, and the maintenance of insurance and indemnity bonds.
These franchises provide for the payment of fees to the issuing authorities and
generally range from 3% to 5% of revenues. The duration of these outstanding
franchises presently varies up to the year 2011. To date, all of RCN's cable
franchises have been renewed or extended, generally at or prior to their stated
expirations and on acceptable terms. Approximately 39 of RCN's hybrid
fiber/coaxial cable systems' franchises are due for renewal within the next
three years. No assurance can be given that RCN will be able to renew its
franchises on acceptable terms. No one franchise accounts for more than 7% of
RCN's total revenue. RCN's five largest franchises account for approximately 27%
of RCN's total revenue.

     The hybrid fiber/coaxial cable systems are also subject to certain service
quality standards and other obligations imposed by the FCC and, where effective
competition has not been demonstrated to exist, to rate regulation by the FCC as
well. RCN's cable television system in Pennsylvania has been operating in a
competitive cable environment for almost 30 years, with approximately 80% of the
homes passed having access to an alternate cable operator, Service Electric
Cable TV. As a result, the Company's Pennsylvania cable system is exempt from
many FCC cable television regulations, including rate regulation. Its other
cable television systems in New York State and New Jersey currently remain
subject to FCC rate regulation. With the passage of the 1996 Act, however, all
cable systems rates will be deregulated as effective competition is shown to
exist in the franchise area, or by March 31, 1999, whichever date is sooner. RCN
anticipates that the remaining provisions of the 1992 Act that do not relate to
rate regulation, such as the provisions relating to retransmission consent and
customer service standards, will remain in place and may serve to reduce the
future operating margins of RCN's hybrid fiber/coaxial cable television
businesses as video programming competition develops in its cable television
service markets.

     The Communications Act requires the FCC to regulate the rates, terms and
conditions imposed by public utilities for cable systems' use of utility pole
and conduit space unless state authorities can demonstrate that they adequately
regulate pole attachment rates. In the absence of state regulation, the FCC
administers pole attachment rates on a formula basis. In some cases, utility
companies have increased pole attachment fees for cable systems that have
installed fiber optic cables and that are using such cables for the distribution
of non-video services. The FCC concluded that, in the absence of state
regulation, it has jurisdiction to determine whether utility companies have
justified their demand for additional rental fees and that the Communications
Act does not permit disparate rates based on the type of service provided over
the equipment attached to the utility's pole. The 1996 Act and the FCC's
implementing regulations modify the current pole attachment provisions of the
Communications Act by immediately permitting certain providers of
telecommunications services to rely upon the protections of the current law and
by requiring that utilities provide cable systems and telecommunications
carriers with nondiscriminatory access to any pole, conduit or right-of-way
controlled by the utility. The FCC has recently adopted new regulations to
govern the charges for pole attachments used by companies provided
telecommunications services, including cable operators. These new pole
attachment rate regulations will become effective five years after enactment of
the 1996 Act, and any increase in attachment rates resulting from the FCC's new
regulations will be phased in equal annual increments over a period of five
years beginning on the effective date of the new FCC regulations. The ultimate
outcome of these rulemakings and the ultimate impact of any revised FCC rate
formula or of any new pole attachment rate regulations on the Company or its
businesses cannot be determined at this time.

     The 1992 Act, the 1996 Act and FCC regulations preclude any satellite video
programmer affiliated with a cable company, or with a common carrier providing
video programming directly to its subscribers, from favoring an affiliated
company over competitors and require such programmers to sell their programming
to other multichannel video distributors. These provisions limit the ability of
program suppliers affiliated with cable companies or with common carriers
providing satellite delivered video programming directly to their subscribers to
offer exclusive programming arrangements to their affiliates. The Communications
Act also includes provisions, among others, concerning horizontal and vertical
ownership of cable systems, customer service, subscriber privacy, marketing
practices, equal employment opportunity, obscene or indecent programming,
regulation of technical standards and equipment compatibility.

     In addition to the FCC regulations noted above, there are other FCC
regulations covering such areas as equal employment opportunity, syndicated
program exclusivity, network program non-duplication, registration of cable
systems, maintenance of various records and public inspection files, microwave
frequency usage, lockbox availability, sponsorship identification, antenna
structure notification, tower marking and lighting, carriage of local sports
broadcast programming, application of rules governing political broadcasts,
limitations on advertising contained in non-broadcast children's programming,
consumer protection and customer service, ownership of home wiring, indecent
programming, programmer access to cable systems, programming agreements,
technical standards, consumer electronics equipment compatibility and closed
captioning. The FCC has the authority to enforce its regulations through the
imposition of substantial fines, the issuance of cease and desist orders and/or
the imposition of other administrative sanctions, such as the revocation of FCC
licenses needed to operate certain transmission facilities often used in
connection with cable operations.

     Other bills and administrative proposals pertaining to cable television
have previously been introduced in Congress or considered by other governmental
bodies over the past several years. It is probable that there will be
legislative proposals in the future by Congress and other governmental bodies
relating to the regulation of communications services.

     Cable television systems are subject to federal compulsory copyright
licensing covering the retransmission of television and radio broadcast signals.
In exchange for filing certain reports and contributing a percentage of their
basic revenues to a federal copyright royalty pool, cable operators can obtain
blanket licenses to retransmit the copyrighted material on broadcast signals.

     The data services business, including Internet access, is largely
unregulated at this time (apart from Federal, state, and local laws and
regulations applicable to businesses in general). However, there can be no
assurance that this business will not become subject to regulatory restraints.
Some jurisdictions have sought to impose taxes and other burdens on providers of
data services, and to regulate content provided via the Internet and other
information services. RCN expects that proposals of this nature will continue to
be debated in Congress and state legislatures in the future. In addition,
although the FCC has on several occasions rejected proposals to impose
additional costs on providers of Internet access service and other data services
to the extent they use local exchange telephone network facilities for access to
their customers, similar proposals may well be considered by the FCC or Congress
in the future.

     The foregoing does not purport to describe all present and proposed
federal, state, and local regulations and legislation affecting the telephone
and video programming industries. Other existing federal regulations, copyright
licensing, and, in many jurisdictions, state and local franchise requirements,
are currently the subject of judicial proceedings, legislative hearings and
administrative proposals which could change, in varying degrees, the manner in
which communications companies operate. The ultimate outcome of these
proceedings, and the ultimate impact of the 1996 Act or any final regulations
adopted pursuant to the new law on RCN or its businesses cannot be determined at
this time.

Employees

     As of December 31, 1997 the Company had 1,150 full-time employees including

Legal Proceedings

     On September 30, 1997, the Yee Family Trusts, as holders of Commonwealth
Telephone's Preferred Stock Series A and Preferred Stock Series B, filed an
action against the Company, Commonwealth Telephone and Cable Michigan in the
Superior Court of New Jersey, Chancery Division. The complaint alleges that
Commonwealth Telephone's distribution of the common stock of RCN and Cable
Michigan in connection with its restructuring (1) constituted a fraudulent
conveyance; (2) breached the terms of a contract between plaintiffs and
Commonwealth; (3) breached the covenant of good faith and fair dealing allegedly
owed plaintiffs; and (4) breached fiduciary duties allegedly owed plaintiffs. On
December 1, 1997, the complaint was amended to allege that Commonwealth
Telephone's distribution of the common stock of RCN and Cable Michigan was an
unlawful distribution in violation of 15 Pa.C.S. 1551(b)(2). The plaintiffs are
seeking to set aside the alleged fraudulent conveyance and unspecified monetary
damages alleged to be in excess of $52 million. The Company believes this
lawsuit is without merit and intends to contest this action vigorously. On
January 9, 1998, the defendants, including RCN, filed a Motion to Dismiss, or in
the Alternative, for Summary Judgment. Plaintiffs' response to this motion is
due on March 9, 1998 and defendants' reply is due on April 6, 1998. The New
Jersey court is scheduled to hear oral argument on the motion on or about April
17, 1998.

     In the normal course of business, there are various legal proceedings
outstanding, including both commercial and regulatory litigation. In the opinion
of management, these proceedings will not have a material adverse effect on the
results of operations or financial condition of the Company.

(1)  No RCN stock options were exercised by the Named Executive Officers during
     the fiscal year ended December 31, 1997.

(2)  Denominated in shares of RCN Common Stock.

(3)  The fair market value of RCN Common Stock at December 31, 1997 was $17.125
     per share.

Effect of Distribution on Equity-Related Benefits

     In connection with the Distribution, each C-TEC option held by the Named
Executive Officers and all other holders of such options was adjusted so that
each such executive officer and other holder currently holds options to purchase
shares of Commonwealth Telephone Common Stock, RCN Common Stock and Cable
Michigan Common Stock, respectively. The number of shares subject to, and the
exercise price of, such options were adjusted to take into account the
Distribution and to ensure that the aggregate intrinsic value of the resulting
RCN, Cable Michigan and Commonwealth Telephone options immediately after the
Distribution was equal to the aggregate intrinsic value of the C-TEC options
immediately prior to the Distribution. Shares of restricted C-TEC Common Stock
awarded under the C-TEC Executive Stock Purchase Plan ("ESPP") and share units
awarded under the ESPP that relate to C-TEC Common Stock were adjusted so that
following the Distribution, each such participant was credited with an aggregate
equivalent value of restricted shares of common stock of Commonwealth Telephone,
the Company and Cable Michigan. See Note (4) to "Security Ownership of Certain
Beneficial Owners and Management."

Pension Benefits

     C-TEC completed a comprehensive study of its employee benefit plans in
1996. As a result of this study, effective after December 31, 1996, in general,
employees other than those of the C-TEC Group no longer accrue benefits under
the C-TEC defined benefit pension plan, but became fully vested in their
benefits accrued through that date. Such benefits, for the Named Executive
Officers affected by this event, computed as the present value at July 31, 1997
of a life annuity beginning at age 65, are as follows: Mr. McCourt, $11,679; Mr.
Mahoney, $29,124; Mr. Godfrey, $10,874; Mr. Haverkate, $41,894; and Mr. Adams,
$7,249.

Directors' Compensation

     Non-employee Directors of the Company will receive a retainer of $900 per
month and will be paid $1,000 for each board meeting attended. The Committee
Chairmen and other committee members will be paid $1,500 and $1,000,
respectively, for each committee meeting attended. Pursuant to the RCN
Corporation 1997 Stock Plan for Non-Employee Directors, the retainer will be
paid in shares of RCN Common Stock and each non-employee director will receive
an annual grant of a non-qualified option covering 4,000 shares of RCN Common
Stock.

Compensation Committee Interlocks and Insider Participation

     The Company has established a Compensation Committee, all the members of
which are non-employee directors.


         SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

     Set forth in the table below is information as of March 1, 1998 (or as of

own more than five percent of the outstanding RCN Common Stock, (ii) each
director of the Company, (iii) each of the Named Executive Officers of the
Company and (iv) all directors and officers of the Company as a group. To the

(2)  Under the ESPP, participating executive officers who forgo current
     compensation are credited with "Share Units," the value of which is based
     on the value of a share of Company Common Stock. ESPP participants who
     elect to receive Share Units in lieu of current compensation are also
     credited with restricted "Matching Shares," which vest over a period of 3
     years from the grant date, subject to continued employment. Matching
     Shares, unless forfeited, have voting and dividend rights. In connection
     with the Distribution, Share Units and Matching Shares were adjusted in an
     equitable manner so that participants were credited with an aggregate
     equivalent value of restricted shares of Commonwealth Telephone, RCN and
     Cable Michigan Common Stock. The holdings indicated include Share Units and
     Matching Shares.

             DESCRIPTION OF THE DISTRIBUTION AND RELATED AGREEMENTS

     This section of the Prospectus describes certain agreements among the
Company, Commonwealth Telephone and Cable Michigan that will govern certain of
the on-going relationships among such entities, and will provide for an orderly
transition to the status of three separate, independent companies. To the extent
that they relate to the Distribution Agreement or the Tax Sharing Agreement
(collectively, the "Distribution Documents"), the following descriptions
describe the Distribution Documents as in effect as of the Distribution, do not
purport to be complete and are qualified in their entirety by reference to the
Distribution Documents, which were filed as exhibits to the Company's
Information Statement on Form 10 ("Form 10"), and are incorporated herein by
reference.

     The Distribution Documents were entered into in connection with the
Distribution and are, therefore, not the result of arm's length negotiation
between unrelated parties as the Company, Commonwealth Telephone and Cable
Michigan have certain common officers and directors. Nevertheless, the
transitional service arrangements in such agreements are designed to reflect
arrangements that would have been agreed upon by parties negotiating at arm's
length. Any additional or modified agreements, arrangements and transactions
entered into between the Company and either or both of Commonwealth Telephone
and Cable Michigan will be negotiated at arm's length.

Background

     On February 12, 1997, the Board of Directors of C-TEC (now Commonwealth
Telephone) approved a plan to restructure C-TEC (the "Restructuring"). Under the
Restructuring, C-TEC would be separated into three different, publicly traded
companies engaged, respectively, in the following businesses:

      (i)  the business of the Company;

     (ii)  a cable television business in the State of Michigan, which would be
           owned by Cable Michigan and would include C-TEC's 61.92% interest in
           Mercom, Inc.; and

    (iii)  C-TEC's Pennsylvania telephone and engineering business, which would
           be owned by Commonwealth Telephone and would consist of C-TEC's
           Commonwealth Telephone Company business (Pennsylvania rural LEC
           operations), C-TEC's Pennsylvania CLEC operations, Commonwealth
           Communications, Inc. (communications engineering) and C-TEC's long
           distance business related to the Commonwealth Telephone Company and
           Pennsylvania CLEC operations.

     Following the Distribution, C-TEC's name was changed to Commonwealth
Telephone Enterprises, Inc.

     The C-TEC Board of Directors determined that the Restructuring and the
subsequent Distribution would, among other things, (i) facilitate possible
future equity or equity-linked offerings by the Company; (ii) facilitate
possible future acquisitions and joint venture investments by the Company; (iii)
facilitate the ability of the Company to grow in both size and profitability;
(iv) allow the management of the Company to focus attention and financial
resources on its business; and (v) allow for the establishment of an employee
stock ownership plan for the employees of the Company with stock that correlates
more closely to the Company's business, as well as permit the Company to offer
other employee incentives that are more directly linked to the performance of
its business.

     On September 30, 1997, C-TEC effected the Distribution by the delivery of
the shares of Company Common Stock to the Distribution Agent for distribution to
the holders of record of C-TEC Common Stock and C-TEC Class B Common Stock. As a
result of the Distribution, 100% of the shares outstanding on such date of
Company Common Stock were distributed to holders of C-TEC Common Equity.

Terms of Distribution Agreement

     Commonwealth Telephone, Cable Michigan and the Company entered into a
Distribution Agreement prior to the Distribution, among other things, to define
certain aspects (other than those with respect to taxes, which shall be governed
by the Tax Sharing Agreement (defined below)) of the relationship among
Commonwealth Telephone, Cable Michigan and the Company after the Distribution
and to provide for the allocation of certain assets and liabilities (other than
those with respect to taxes, which shall be governed by the Tax Sharing
Agreement) among Commonwealth Telephone, Cable Michigan and the Company.

     Indemnification

     The Company, Cable Michigan and Commonwealth Telephone have agreed to
indemnify one another against certain liabilities. The Company has agreed to
indemnify Commonwealth Telephone and its subsidiaries (collectively, the
"Commonwealth Telephone Group") and the respective directors, officers,
employees and affiliates of each person in the Commonwealth Telephone Group
(collectively, the "Commonwealth Telephone Indemnitees") and Cable Michigan and
its subsidiaries (collectively, the "Cable Michigan Group") and the respective
directors, officers, employees and affiliates of each person in the Cable
Michigan Group (collectively, the "Cable Michigan Indemnitees") from and against
any and all damage, loss, liability and expense ("Losses") incurred or suffered
by any of the Commonwealth Telephone Indemnitees or the Cable Michigan
Indemnitees, respectively, (i) arising out of, or due to the failure of the
Company or any of its subsidiaries at the time of the Distribution
(collectively, the "Company Group") to pay, perform or otherwise discharge any
of the Company Liabilities (as defined below), (ii) arising out of the breach by
any member of the Company Group of any obligation under the Distribution
Agreement or any of the other Distribution Documents and (iii) in the case of
the Commonwealth Telephone Indemnitees, arising out of the provision by the
Commonwealth Telephone Group of the services described below to the Company
Group except to the extent that such Losses result from the gross negligence or
willful misconduct of a Commonwealth Telephone Indemnitee. "Company Liabilities"
refers to (i) all liabilities of the Company Group under the Distribution
Agreement or any of the other Distribution Documents, (ii) all other liabilities
of the Company, Cable Michigan or Commonwealth Telephone (or their respective
subsidiaries), except as specifically provided in the Distribution Agreement or
any of the other Distribution Documents and whether arising before, on or after
the Distribution Date, to the extent such liabilities arise primarily from or
relate primarily to the management or conduct of the Company Businesses prior to
the effective time of the Distribution (the liabilities in clauses (i) and (ii)
collectively, the "True Company Liabilities") and (iii) 30% of the Shared
Liabilities (as defined below).

     Cable Michigan has agreed to indemnify the Company Group and the respective
directors, officers, employees and Affiliates of each Person in the Company
Group (collectively, the "Company Indemnitees") and the Commonwealth Telephone
Indemnitees from and against any and all Losses incurred or suffered by any of
the Company Indemnitees or the Commonwealth Telephone Indemnitees, respectively,
(i) arising out of, or due to the failure of any Person in the Cable Michigan
Group to pay, perform or otherwise discharge any of the Cable Michigan
Liabilities (as defined below), (ii) arising out of the breach by any member of
the Cable Michigan Group of any obligation under the Distribution Agreement or
any of the other Distribution Documents, (iii) in the case of the Commonwealth
Telephone Indemnitees, arising out of the provision by the Commonwealth
Telephone Group of Services (as defined below) to the Cable Michigan Group
except to the extent that such Losses result from the gross negligence or
willful misconduct of a Commonwealth Telephone Indemnitee and (iv) in the case
of the Company Indemnitees, arising out of the provision by the Company of the
services described below to the Cable Michigan Group except to the extent that
such Losses result from the gross negligence or willful misconduct of a Company
Indemnitee. "Cable Michigan Liabilities" refers to (i) all liabilities of the
Cable Michigan Group under the Distribution Agreement or any of the other
Distribution Documents, (ii) all other liabilities of the Company, Cable
Michigan or Commonwealth Telephone (or their respective subsidiaries), except as
specifically provided in the Distribution Agreement or any of the other
Distribution Documents and whether arising before, on or after the Distribution
Date, to the extent such liabilities arise primarily from or relate primarily to
the management or conduct of the business of the Cable Michigan Group prior to
the effective time of the Distribution (the liabilities in clauses (i) and (ii)
collectively, the "True Cable Michigan Liabilities") and (iii) 20% of the Shared
Liabilities (as defined below).

     Commonwealth Telephone has agreed to indemnify the Company Indemnitees and
the Cable Michigan Indemnitees from and against any and all Losses incurred or
suffered by any of the Company Indemnitees or the Cable Michigan Indemnitees,
respectively, (i) arising out of, or due to the failure of any Person in the
Commonwealth Telephone Group to pay, perform or otherwise discharge any of the
Commonwealth Telephone Liabilities (as defined below), (ii) arising out of the
breach by any member of the Commonwealth Telephone Group of any obligation under
the Distribution Agreement or any of the other Distribution Documents and (iii)
in the case of the Company Indemnitees, arising out of the provision by the
Company of the services described below to the Commonwealth Telephone Group
except to the extent that such Losses result from the gross negligence or
willful misconduct of a Company Indemnitee. "Commonwealth Telephone Liabilities"
refers to (i) all liabilities of the Commonwealth Telephone Group under the
Distribution Agreement or any of the other Distribution Documents, (ii) all
other liabilities of the Company, Cable Michigan or Commonwealth Telephone (or
their respective subsidiaries), except as specifically provided in the
Distribution Agreement or any of the other Distribution Documents and whether
arising before, on or after the Distribution Date, to the extent such
liabilities arise primarily from or relate primarily to the management or
conduct of the business of the Commonwealth Telephone Group prior to the
effective time of the Distribution (the liabilities in clauses (i) and (ii)
collectively, the "True Commonwealth Telephone Liabilities") and (iii) 50% of
the Shared Liabilities (as defined below).

     "Shared Liability" means any liability (whether arising before, on or after
the Distribution Date) of the Company, Cable Michigan or Commonwealth Telephone
or their respective subsidiaries which (i) (a) arises from the conduct of the
corporate overhead function with respect to Commonwealth Telephone and its
subsidiaries prior to the effective time of the Distribution with certain
exceptions or (b) is one of certain fees and expenses incurred in connection
with the Restructuring and (ii) is not a True Commonwealth Telephone Liability,
a True Cable Michigan Liability or a True Company Liability.

     The Company, Cable Michigan and Commonwealth Telephone have also generally
agreed to indemnify each other and each other's affiliates and controlling
persons from certain liabilities under the securities laws in connection with
the Company's Form 10, the Company's offering memorandum in connection with the
1997 Notes Offering and Cable Michigan's Informational Statement on Form 10 and
Cable Michigan Prospectus. For information regarding indemnification for tax
liabilities, see "--Tax Sharing Agreement."

     The Company does not believe that any of the foregoing indemnities will
have a material adverse effect on the business, financial condition or results
of operations of the Company.

     The Distribution Agreement also includes procedures for notice and payment
of indemnification claims and provides that the indemnifying party may assume
the defense of claims or suits brought by third parties for non-Shared
Liabilities and may participate in the defense of claims or suits brought by
third parties for Shared Liabilities. RCN is entitled to assume the defense of
claims or suits brought by third parties for Shared Liabilities. Any
indemnification paid under the foregoing indemnities is to be paid net of the
amount of any insurance or other amounts that would be payable by any third
party to the indemnified party in the absence of such indemnity.

     Employee Matters

     Under the Distribution Agreement, Cable Michigan, RCN and Commonwealth
Telephone agreed generally to assume employee benefits-related liabilities with
respect to its current and, in some cases, former employees.

     Transitional Services and Arrangements

     The Company has agreed to provide or cause to be provided to the
Commonwealth Telephone Group certain specified services for a transitional
period after the Distribution. The transitional services to be provided are the
following: (i) accounting, (ii) payroll, (iii) management supervision, (iv) cash
management, (v) human resources and benefit plan administration, (vi) insurance
administration, (vii) legal, (viii) tax, (ix) internal audit, (x) investor and
public relations and (xi) other miscellaneous administrative services. The fee
per year for these services will be 3.5% of the first $175 million of revenue of
the Commonwealth Telephone Group and 1.75% of any additional revenue. Based on
the Commonwealth Telephone Group's revenue for 1996, the fee for that year would
have been approximately $6,326,000.

     The Company has also agreed to provide or cause to be provided to the Cable
Michigan Group certain specified services for a transitional period after the
Distribution. The transitional services to be provided are the following: (i)
customer service, (ii) marketing, (iii) accounting, (iv) payroll, (v) management
supervision, (vi) cash management, (vii) human resources and benefit plan
administration, (viii) insurance administration, (ix) legal, (x) tax, (xi)
internal audit, (xii) programming administration, (xiii) billing, (xiv) monthly
cable guides, (xv) investor and public relations, (xvi) provision of third party
programming and (xvii) other miscellaneous administrative services. Subject to
certain limitations, the fee per year for services listed in items (ii)-(xii),
(xv) and (xvii) will be 4.0% of the revenues of the Cable Michigan Group plus a
direct allocation of certain consolidated cable administrative functions. Based
on the Cable Michigan Group's revenue for 1996 and the allocation of certain
consolidated cable administrative functions, the charge for such services for
that year would have been approximately $4,418,000. The charge for customer
service listed in item (i) along with the billing service listed in item (xiii)
will be a pro rata share (based on the relative number of subscribers) of the
fees and expenses incurred by the Company to provide such customer and billing
services for the Company and the Cable Michigan Group. Based on this allocation
arrangement, the charge to Cable Michigan for such customer and billing services
would have been approximately $3,114,000 in 1996. The third party expense
incurred by RCN to obtain third party programming and monthly cable guides for
Cable Michigan referred to in items (xiv) and (xvi) above will be reimbursed to
RCN by Cable Michigan, and no additional fee will be charged with respect
thereto.

     Commonwealth Telephone has agreed to provide or cause to be provided to the
Company Group and the Michigan Group financial data processing applications,
lockbox services, storage facilities, LAN and WAN support services, building
maintenance and other miscellaneous administrative services for a transitional
period after the Distribution. The fees for such services and arrangements will
be an allocated portion (based on relative usage) of the cost incurred by
Commonwealth Telephone to provide such services and arrangements to all three
groups. Based on this allocation arrangement, the fee for providing such
services and arrangements to the Company Group and the Cable Michigan Group
would have been approximately $753,000 and $248,000, respectively, for 1996.

     The nature, scope and timing of the foregoing services are to be
substantially consistent with the nature, scope and timing of the service
provider's services prior to the Distribution, provided that the service
provider shall not be obligated to hire additional or replacement employees, or
increase the compensation of its existing employees, in order to provide the
services. The services commenced on the Distribution Date and will terminate
upon 60 days notice by either the service provider or the relevant service
recipient, except that the billing, customer service, programming administration
and provision of third party programming services provided by RCN to Cable
Michigan may not be terminated by RCN on less than one year advance notice to
Cable Michigan. A service recipient may also terminate individual services by
giving 60 days notice to the applicable service provider.

     Intercompany Accounts; Intellectual Property Rights and Licenses

     Except as otherwise provided in the Tax Sharing Agreement or the
Distribution Agreement, all intercompany receivable, payable and loan balances
among the Company Group, the Cable Michigan Group and the Commonwealth Telephone
Group were settled prior to the Distribution by payment in full by the party or
parties owing any such obligation; provided however, that certain de minimis
accounts payable and accounts receivable may be settled within 30 days after the
Distribution. The Distribution Agreement provides that all arrangements and
agreements between the parties terminated as of the Distribution Date other than
the Distribution Documents and certain commercial contracts on terms that
management believes to be arm's-length. These contracts comprise switch and
facilities leases, an Internet access resale agreement, an interim carrier
agreement, local and long distance phone service agreements, a maintenance
agreement and switch monitoring and traffic capacity services agreements.

     None of the Groups will have any right or license in or to any technology,
software, intellectual property, know-how or other proprietary right owned,
licensed or held for use by another Group.

     Miscellaneous

     As a result of the Distribution, there exist relationships that may lead to
conflicts of interest. Each of the Company, Commonwealth Telephone and Cable
Michigan are effectively controlled by Kiewit Telecom. In addition, the majority
of the Company's named executive officers are also directors and/or executive
officers of Commonwealth Telephone or Cable Michigan. See "Management." In
particular, David C. McCourt, Chairman and Chief Executive Officer of the
Company, has served as a director and Chairman and Chief Executive Officer of
Cable Michigan since the Distribution and as a director and Chairman and Chief
Executive Officer of C-TEC/Commonwealth Telephone since October 1993. Mr.
McCourt expects to devote approximately 70% of his time to managing the affairs
of the Company. In addition, Michael J. Mahoney, who has been President and
Chief Operating Officer, as well as a director, of the Company since the
Distribution is also a director of Commonwealth Telephone. Mr. Mahoney expects
to devote approximately 85-90% of his time to managing the affairs of the
Company. The Company's other named executive officers expect to devote the
following approximate portions of their time to managing the affairs of the
Company: Mr. Godfrey (80%); Mr. Haverkate (75%) and Mr. Adams (100%). The
success of the Company may be affected by the degree of involvement of its
officers and directors in the Company's business and the abilities of the
Company's officers, directors and employees in managing both the Company and the
operations of Cable Michigan and/or Commonwealth Telephone. Potential conflicts
of interest will be dealt with on a case-by-case basis taking into consideration
relevant factors including the requirements of NASDAQ and prevailing corporate
practices.

Tax Sharing Agreement

     The Tax Sharing Agreement, by and among the Company, Cable Michigan and
Commonwealth Telephone (the "Tax Sharing Agreement"), governs contingent tax
liabilities and benefits, tax contests and other tax matters with respect to tax
returns filed with respect to tax periods, in the case of the Company, ending or
deemed to end on or before the Distribution Date. Under the Tax Sharing
Agreement, Adjustments (as defined in the Tax Sharing Agreement) to taxes that
are clearly attributable to the Company Group, the Cable Michigan Group, or the
Commonwealth Telephone Group will be borne solely by such Group. Adjustments to
all other tax liabilities will be borne 50% by Commonwealth Telephone, 30% by
the Company and 20% by Cable Michigan.

     Notwithstanding the above, if as a result of the acquisition of all or a
portion of the capital stock or assets of the Company, the Distribution or the
Cable Michigan Distribution fails to qualify as a tax-free distribution under
Section 355 of the Code, then the Company will be liable for any and all
increases in tax attributable thereto.


                       DESCRIPTION OF CERTAIN INDEBTEDNESS

     This section of the Prospectus describes the terms and conditions of the
Credit Agreement that certain subsidiaries of the Company have in place and of
the 10% Senior Notes and the 11-1/8% Senior Discount Notes which RCN has
outstanding. The following description does not purport to be complete and is
subject to, and is qualified in its entirety by reference to, all of the
provisions of the Credit Agreement, which was an exhibit to the Company's Form
10 filed with the Commission, and to the provisions of the documents governing
such 10% Senior Notes and the 11-1/8% Senior Discount Notes, which were filed as
exhibits to the Company's Registration Statement filed with the Commission, and
are incorporated herein by reference.

Credit Agreement

     Capitalized terms used in this Section and not otherwise defined herein are
used as defined in the Credit Agreement.

     Certain of the Company's direct and indirect subsidiaries, namely, RCN
Cable and its subsidiaries RCN of New Jersey, Inc. (formerly ComVideo Systems,
Inc.; "ComVideo") and RCN of Southeast New York, Inc. (formerly C-TEC Cable
Systems of New York, Inc.; "Cable Systems New York" and together with ComVideo,
the "Borrowers"), have in place two secured credit facilities (the "Credit
Facilities") pursuant to a single credit agreement with a group of lenders for
which First Union National Bank acts as agent (the "Credit Agreement"), which
was effective as of July 1, 1997 (the "Closing Date"). The first is a five-year
revolving credit facility in the amount of $25 million (the "Revolving Credit
Facility"). The second is an eight-year term credit facility in the amount of
$100 million (the "Term Credit Facility").

     Borrowings under the Credit Facilities are available for the following
purposes: (i) to refinance existing indebtedness of the Borrowers, (ii) to
finance an equity investment by RCN Cable in RCN Telecom Services, Inc. (a
member of the RCN Group), (iii) to finance permitted acquisitions, and (iv) for
capital expenditures, working capital and general corporate purposes. Borrowings
under the Credit Agreement are subject to the conditions that there can be no
default or event of default under the Credit Agreement and that the
representations and warranties of the Borrowers contained in the Credit
Agreement and related pledge agreements must be true. Each Borrower is jointly
and severally liable for all borrowings and other obligations under the Credit
Facilities.

     The interest rate on the Credit Facilities is, at the election of the
Borrowers, based on either a LIBOR or a Base Rate option (each as defined in the
Credit Agreement). In the case of the LIBOR option, the interest rate includes a
spread that varies, based on RCN Cable's Leverage Ratio (defined as the ratio of
Total Debt at the last day of the most recently ended fiscal quarter to
Operating Cash Flow for the four fiscal quarters then ended), from 50 basis
points to 125 basis points. In the case of the Revolving Credit Facility, a fee
of 20 basis points on the unused revolving commitment accrues and is payable
quarterly in arrears.

     The entire amount of the Revolving Credit Facility is available to the
Borrowers until June 30, 2002. As of December 31, 1997, $3 million of principal
was outstanding thereunder. Revolving loans may be repaid and reborrowed from
time to time.

     The entire $100 million of the Term Credit Facility was borrowed, all of
which remained outstanding as of December 31, 1997. The Term Credit Facility
must be repaid over six years in quarterly installments, at the end of
September, December, March and June of each year from September 30, 1999 through
June 30, 2005. The aggregate annual installments payable on the term loan are as
follows:


          1999..................................           $3,750,000   
          2000..................................          $11,250,000   
          2001..................................          $16,250,000   
          2002..................................          $17,500,000   
          2003..................................          $19,374,000   
          2004..................................          $21,250,000   
          2005..................................          $10,626,000   
          
     The Borrowers have the option to repay the Term Credit Facility in whole or
in part at any time, without penalty, subject to customary "breakage" charges.
Any amount of the Term Credit Facility that is repaid may not be reborrowed.

     The Borrowers are required to apply 100% of the net cash proceeds realized
from certain asset sales, certain payments under insurance policies and certain
incurrences of additional debt to repay the Revolving Credit Facility. Any
excess amounts of such net cash proceeds not applied to repay Revolving Credit
Facility are applied to reduce the scheduled installments of the Term Credit
Facility on a pro rata basis.

     All borrowings under the Credit Facilities will be pari passu, and will be
secured under a common collateral package including (i) a first priority pledge
by RCN Cable of 100% of the stock in ComVideo (which will be given only after
approval from the appropriate regulatory authority in New Jersey is granted) and
in Cable Systems New York; (ii) a first priority pledge by ComVideo of 100% of
its partnership interests in Home Link Communications of Princeton, L.P. ("Home
Link") at such time that ComVideo has acquired 100% of the partnership interests
in Home Link (at which time Home Link will become a Borrower) and subject also
to approval of the appropriate regulatory authority in New Jersey being granted;
(iii) a first priority pledge by each Borrower of 100% of the stock owned by it
in each other material subsidiary of such Borrower created after the Closing
Date; and (iv) a first priority pledge by RCN of 100% of the stock of RCN Cable.
In addition, the Borrowers are subject to a prohibition on granting other
negative pledges to other parties on the assets of RCN Cable and certain of its
subsidiaries (subject to customary exceptions). The stock and assets of RCN
Telecom Services of Pennsylvania, Inc. (formerly C-TEC Cable Systems of
Pennsylvania, Inc.), RCN Telecom Services, Inc. and RCN International Holdings,
Inc. are excluded from the security arrangements.

     The Credit Agreement contains customary covenants for facilities of this
nature, including covenants limiting debt, liens, investments, consolidations,
mergers, acquisitions and sales of assets, payment of dividends and other
distributions, making of capital expenditures and transactions with affiliates.
The Credit Agreement requires the Borrowers, Home Link and all subsidiaries of
the Borrowers created after the Closing Date on a combined basis to maintain the
following financial ratios: (i) the ratio of Total Debt at any fiscal quarter
end to Operating Cash Flow for the trailing four fiscal quarters is not to
exceed 5.0:1 initially, adjusting over time to 4.0:1; (ii) the ratio of
Operating Cash Flow to Interest Expense for any four consecutive fiscal quarters
is not to fall below 2.75:1 for periods ending during the first 3 years after
the Closing Date, adjusting to 3.0:1 thereafter; and (iii) the ratio of
Operating Cash Flow (minus certain capital expenditures, cash taxes and cash
dividends) to Fixed Charges (defined as scheduled principal payments and
interest expense) for any four consecutive quarters is not to fall below 1.0:1
for periods ending on or before December 31, 2000 and adjusting to 1.05:1
thereafter.

     The Credit Agreement includes customary events of default. Upon the
occurrence of any event of default, the lenders may accelerate the outstanding
loans and cancel any unborrowed commitment. These events of default include
payment and covenant defaults (subject in certain cases to a grace period),
misrepresentations, cross default to certain other debt, bankruptcy, ERISA and
judgment defaults and a change of control default. For this purpose, "change of
control" is defined to mean any time that (A) PKS shall cease to hold, either
directly or indirectly through one or more PKS entities, shares of RCN
constituting at least thirty percent (30%) of the number of outstanding common
shares or at least thirty percent (30%) of the voting power represented by the
outstanding voting shares of RCN (in each case, outstanding shares excluding
shares issued after the Distribution Date (i) for cash, (ii) in consideration
for the acquisition of any investment or property or the provision of services,
(iii) upon the exercise of any warrant, option, convertible security or similar
instrument issued after the Distribution Date for consideration described in
clauses (i) and (ii) or (iv) in connection with an employee stock option plan
and similar benefit arrangement adopted after the Distribution Date by RCN or
any of its wholly owned subsidiaries), (B) any person (other than PKS or a PKS
entity) or group of persons shall have acquired in one or more series of
transactions beneficial ownership of more than fifty-one percent (51%) of the
outstanding common stock or of the voting power represented by the outstanding
voting shares of RCN or (C) RCN shall cease to hold, directly or indirectly, all
of the outstanding shares of capital stock of RCN Cable.

1997 Notes Offering

     10% Senior Notes due 2007

     The 10% Senior Notes were issued under an indenture dated October 17, 1997
between RCN and The Chase Manhattan Bank, as Trustee (the "10% Indenture"). The
10% Senior Notes are general senior obligations of RCN, limited to $225 million
aggregate principal amount and will mature on October 15, 2007. The 10% Senior
Notes will be collateralized, pending disbursement pursuant to the Escrow and
Security Agreement dated as of October 17, 1997 among RCN, The Chase Manhattan
Bank, as Trustee, and The Chase Manhattan Bank, as Escrow Agent (the "Escrow
Agreement"), by a pledge of the Escrow Account (as defined in the Escrow
Agreement), which contains approximately $61 million of the net proceeds from
the sale of the 10% Senior Notes, representing funds that, together with the
proceeds from the investment thereof, will be sufficient to pay interest on the
10% Senior Notes for six scheduled interest payments. Interest on the 10% Senior
Notes will be payable in cash at a rate of 10% per annum semi-annually in
arrears on each April 15 and October 15, commencing April 15, 1998.

     The 10% Indenture contains provisions which are substantially similar to
the ones which will be contained in the indenture governing the Notes, including
certain covenants that, among other things, limit the ability of RCN and its
subsidiaries to incur indebtedness, pay dividends, prepay subordinated
indebtedness, repurchase capital stock, engage in transactions with stockholders
and affiliates, create liens, sell assets and engage in mergers and
consolidations.

     The 10% Senior Notes are redeemable, in whole or in part, at any time on or
after October 15, 2002 at the option of RCN. The 10% Senior Notes may be
redeemed at redemption prices starting at 105% of the principal amount and
declining to 100% of the principal amount, plus any accrued and unpaid interest.

     11-1/8% Senior Discount Notes due 2007

     The 11-1/8% Senior Discount Notes were issued under an indenture dated
October 17, 1997 between RCN and The Chase Manhattan Bank, as Trustee (the
"11-1/8% Indenture"). The 11-1/8% Senior Discount Notes are general senior
obligations of RCN, limited to $601,045,000 aggregate principal amount at
maturity and will mature on October 15, 2007. The 11-1/8% Senior Discount Notes
were issued at a discount to yield gross proceeds of $350,000,524. The 11-1/8%
Senior Discount Notes will not bear cash interest prior to October 15, 2002. The
yield to maturity of the 11-1/8% Senior Discount Notes, determined on a
semi-annual bond equivalent basis, will be 11-1/8% per annum.

     The 11-1/8% Indenture contains provisions which are substantially similar
to the ones which will be contained in the indenture governing the Notes,
including certain covenants that, among other things, limit the ability of RCN
and its subsidiaries to incur indebtedness, pay dividends, prepay subordinated
indebtedness, repurchase capital stock, engage in transactions with stockholders
and affiliates, create liens, sell assets and engage in mergers and
consolidations.

     The 11-1/8% Senior Discount Notes are redeemable, in whole or in part, at
any time on or after October 15, 2002 at the option of RCN. The 11-1/8% Senior
Discount Notes may be redeemed at redemption prices starting at 105.562% of the
principal amount at maturity and declining to 100% of the principal amount at
maturity, plus any accrued and unpaid interest.


                          DESCRIPTION OF THE NEW NOTES

     The New Notes will be issued under an Indenture (the "Indenture") dated as
of February 6, 1998 between RCN and The Chase Manhattan Bank, as trustee (in
such capacity, the "Trustee"). The Indenture has been filed as an exhibit to the
Registration Statement of which this Prospectus constitutes a part. Upon the
issuance of the New Notes, the Indenture will be subject to the Trust Indenture
Act of 1939, as amended (the "Trust Indenture Act"). The following summary of
certain provisions of the Indenture does not purport to be complete and is
subject to, and is qualified in its entirety by reference to all of the
provisions of the Indenture, including the definitions of certain terms therein
and those terms made a part of the Indenture by reference to the Trust Indenture
Act of 1939, as in effect on the date of such Indenture, and to the Trust
Indenture Act, in the case of the New Notes. Whenever particular provisions or
definitions of the Indenture, the Notes or the terms defined therein are
referred to herein, such provisions or definitions are incorporated herein by
reference. As used in this section, "Company" refers to RCN Corporation. The
definitions of certain capitalized terms used in the following summary are set
forth below under "--Certain Definitions."

General

     The terms of the New Notes are identical in all material respects to the
terms of the Old Notes, except for certain transfer restrictions and
registration rights to the Old Notes and except that, if the Exchange Offer is
required to be consummated under the Registration Rights Agreement and the
Company fails to consummate the Exchange Offer within 135 days after the Issue
Date, then the interest rate on the Old Notes will increase, with respect to the
each 90-day period until the consummation of the Exchange Offer in an amount
equal to 0.25% per annum of the principal amount of the Notes, subject to a
maximum amount of 1.00% of the principal amount of the Notes.

     The Notes will be issued only in registered form, without coupons, in
denominations of $1,000 and integral multiples of $1,000. See "Book-Entry;
Delivery and Form." Principal of, premium, if any, and interest on the Notes are
payable, and the Notes are exchangeable and transferable, at the office or
agency of RCN in the City of New York maintained for such purposes (which
initially will be the corporate trust office of the Trustee). See "Book-Entry;
Delivery and Form." No service charge will be made for any registration of
transfer, exchange or redemption of the Notes, except in certain circumstances
for any tax or other governmental charge that may be imposed in connection
therewith.

     Any Old Notes that remain outstanding after the completion of an Exchange
Offer, together with the New Notes issued in connection with such Exchange
Offer, will be treated as a single class of securities under the Indenture.

Maturity, Interest and Principal

     The New Notes will be general senior unsecured obligations of RCN, limited
to $567,000,000 aggregate principal amount at maturity, and will mature on
February 15, 2008. See "--Ranking." The Old Notes were issued at a discount to
yield gross proceeds of $350,587,440. See "Certain U.S. Federal Income Tax
Considerations." The Notes will not bear cash interest prior to February 15,
2003. Commencing on August 15, 2003, interest on the Notes will be payable, in
cash at a rate of 9.80% per annum, semi-annually in arrears on each February 15
and August 15 to the holders of record of Notes at the close of business on the
February 1 and August 1 immediately preceding such interest payment date.
Interest will accrue from the most recent interest payment date to which
interest has been paid or duly provided for or, if no interest has been paid or
duly provided for, from February 15, 2003. Interest will be computed on the
basis of a 360-day year of twelve 30-day months. Interest on overdue principal
and, to the extent permitted by law, on overdue installments of interest will
accrue at the rate of interest borne by the Notes. The yield to maturity of the
Notes, determined on a semi-annual bond equivalent basis, will be 9.80% per
annum.

Redemption

     Optional Redemption by RCN. The Notes will be redeemable, in whole or in
part, at any time on or after February 15, 2003 at the option of RCN, upon not
less than 30 nor more than 60 days' notice, at the redemption prices (expressed
as percentages of principal amount at maturity) set forth below, plus accrued
and unpaid interest to the redemption date, if redeemed during the 12-month
period beginning February 15 of the years indicated below:

Year                                                  Redemption Price
- ----                                                  ----------------
2003................................................      104.900%
2004................................................      103.267%
2005................................................      101.633%
2006 and thereafter.................................      100.000%

     Redemption Following Public Equity Offerings. Notwithstanding the
foregoing, on or prior to February 15, 2001, RCN may, at its option, use the net
proceeds of one or more Public Equity Offerings (as defined below) yielding
gross cash proceeds of not less than $30 million to redeem up to an aggregate of
35% of the aggregate principal amount at maturity of Notes originally issued, in
each case on a pro rata basis (or as nearly pro rata as practicable), at a
redemption price of 109.80% of the Accreted Value of Notes; provided that not
less than 65% of the originally issued aggregate principal amount at maturity of
Notes would remain outstanding immediately after such redemption. To effect the
foregoing redemption, RCN must mail a notice of redemption not later than 60
days after the consummation of the Public Equity Offering that resulted in the
requisite gross proceeds.

     As used above, "Public Equity Offering" means an underwritten public
offering of Common Stock of RCN effected on a primary basis and registered with
the Commission under the Securities Act.

     Selection; Effect of Redemption Notice. Notice of an optional redemption
must be given no less than 30 nor more than 60 days prior to the applicable
redemption date. In the case of a partial redemption of an issue of Notes,
selection of the Notes for redemption will be made by lot, pro rata or by such
other method as the applicable Trustee in its sole discretion deems fair and
appropriate or in such manner as complies with the requirements of the principal
securities exchange, if any, on which the applicable Notes being redeemed are
listed and of the Depository Trust Company ("DTC"); provided that any redemption
following one or more Public Equity Offerings will be made on a pro rata or on
as nearly a pro rata basis as practicable (subject to the procedures of DTC).
Upon giving of a redemption notice, interest on Notes called for redemption will
cease to accrue from and after the date fixed for redemption (unless RCN
defaults in providing the funds for such redemption) and, upon redemption on
such redemption date, such Notes will cease to be outstanding.

Mandatory Redemption

     Sinking Fund.   RCN will not be required to make any mandatory sinking fund
 payments in respect of the Notes.

     Offers to Purchase upon Change of Control and Certain Asset Sales.
Following the occurrence of a Change of Control, RCN will be required to make an
offer to purchase all outstanding Notes at a price of 101% of the Accreted Value
thereof plus accrued and unpaid interest, if any, to the date of purchase, and
purchase all Notes validly tendered pursuant thereto. In addition, RCN may be
obligated to make an offer to purchase Notes with a portion of the Net Cash
Proceeds of certain Asset Sales at a price of 100% of the Accreted Value thereof
plus accrued and unpaid interest, if any, to the date of purchase. See
"--Certain Covenants--Change of Control" and "--Certain Covenants--Disposition
of Proceeds of Asset Sales," respectively.

Ranking

     The indebtedness of RCN evidenced by the Notes will rank senior in right of
payment to all subordinated indebtedness of RCN and pari passu in right of
payment with all other existing and future unsubordinated indebtedness of RCN.
RCN is a holding company with limited assets and no business operations of its
own. RCN operates its business through its subsidiaries. Any right of RCN and
its creditors, including holders of the Notes, to participate in the assets of
any of RCN's subsidiaries upon any liquidation or administration of any such
subsidiary will be subject to the prior claims of the subsidiary's creditors,
including trade creditors. For a discussion of certain adverse consequences of
RCN being a holding company and of the terms of potential future indebtedness of
RCN and its subsidiaries, see "Risk Factors--Holding Company Structure;
Structural Subordination."

Certain Covenants

     Set forth below are certain covenants that are contained in the Indenture.

     Limitation on Additional Indebtedness. The Indenture provides that RCN will
not, and will not permit any Restricted Subsidiary or Restricted Affiliate to,
directly or indirectly, create, incur, assume, issue, guarantee or in any manner
become directly or indirectly liable for or with respect to, contingently or
otherwise, the payment of (collectively, to "incur") any Indebtedness (including
any Acquired Indebtedness), except for Permitted Indebtedness; provided that (A)
(i) RCN will be permitted to incur Indebtedness (including Acquired Indebtedness
and Buildout Indebtedness) and (ii) a Restricted Subsidiary or Restricted
Affiliate will be permitted to incur Acquired Indebtedness or Buildout
Indebtedness, if, in either case, after giving pro forma effect to such
incurrence (including the application of the net proceeds therefrom), either (X)
the ratio of Total Consolidated Indebtedness to Consolidated Pro Forma Operating
Cash Flow would not be greater than or equal to 5.5:1.0 if such Indebtedness is
incurred prior to October 15, 2000 or 5.0:1.0 if such Indebtedness is incurred
on or after October 15, 2000 or (Y) the ratio of Total Consolidated Indebtedness
to Total Invested Equity Capital would not exceed 2.0:1.0 and (B) on or after
October 15, 2002, a Restricted Affiliate will be permitted to incur Acquired
Indebtedness or Buildout Indebtedness, if, after giving pro forma effect to such
incurrence (including the application of the net proceeds therefrom), the ratio
of Total Affiliate Indebtedness to Affiliate Pro Forma Operating Cash Flow of
such Restricted Affiliate would not be greater than or equal to 4.0:1.0.

     Limitation on Restricted Payments. The Indenture provides that RCN will
not, and will not permit any of the Restricted Subsidiaries or Restricted
Affiliates to, make, directly or indirectly, any Restricted Payment unless:

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

    (ii) immediately after giving effect to such Restricted Payment, RCN would
     be able to incur $1.00 of Indebtedness under clause (A)(X) of the proviso
     of the covenant described under "Limitation on Additional Indebtedness";
     and

     (iii) immediately after giving effect to such Restricted Payment, the
     aggregate amount of all Restricted Payments declared or made on or after
     the Issue Date and all Designation Amounts does not exceed an amount equal
     to the sum of, without duplication, (a) 50% of cumulative Consolidated Net
     Income accrued on a cumulative basis during the period beginning on January
     1, 1998 and ending on the last day of the fiscal quarter of RCN immediately
     preceding the date of such proposed Restricted Payment (or, if such
     cumulative Consolidated Net Income for such period is a deficit, minus 100%
     of such deficit) plus (b) the aggregate net cash proceeds received by RCN
     from the issue or sale (other than to a Restricted Subsidiary or to a
     Restricted Affiliate) of its Capital Stock (other than Disqualified Stock)
     on or after the Issue Date (including, without duplication, upon the
     exercise of options, warrants or rights) plus (c) the aggregate net
     proceeds received by RCN from the issuance (other than to a Restricted
     Subsidiary or to a Restricted Affiliate) on or after the Issue Date of its
     Capital Stock (other than Disqualified Stock) upon the conversion of, or
     exchange for, Indebtedness of RCN or a Restricted Subsidiary plus (d) in
     the case of the disposition or repayment of any Investment constituting a
     Restricted Payment (other than an Investment made pursuant to clause (v),
     (vi) or (vii) of the following paragraph) made after the Issue Date an
     amount equal to the lesser of the return of capital with respect to such
     Investment and the cost of such Investment, in either case, less the cost
     of the disposition of such Investment plus (e) in the case of the
     Revocation of the Designation of a Subsidiary as an Unrestricted
     Subsidiary, an amount equal to the consolidated net Investment in such
     Subsidiary on the date of Revocation but not in an amount exceeding the net
     amount of any Investments constituting Restricted Payments made (or deemed
     made) in such Subsidiary after the Issue Date plus (f) in the case of the
     JV Designation after the Issue Date of a New Joint Venture as a Restricted
     Affiliate, an amount equal to the consolidated net Investment in such New
     Joint Venture on the date of such JV Designation but not in an amount
     exceeding the net amount of any Investments constituting Restricted
     Payments made (or deemed made) in such New Joint Venture after the Issue
     Date. For purposes of the preceding clauses (b) and (c) and without
     duplication, the value of the aggregate net cash proceeds received by RCN
     upon the issuance of Capital Stock either upon the conversion of
     convertible Indebtedness or in exchange for outstanding Indebtedness or
     upon the exercise of options, warrants or rights will be the net cash
     proceeds received upon the issuance of such Indebtedness, options, warrants
     or rights plus the incremental amount received by RCN upon the conversion,
     exchange or exercise thereof.

     For purposes of determining the amount expended for Restricted Payments,
cash distributed shall be valued at the face amount thereof and property other
than cash shall be valued at its Fair Market Value.

     The provisions of this covenant shall not prohibit: (i) the payment of any
dividend or other distribution within 60 days after the date of declaration
thereof, if at such date of declaration such payment would comply with the
provisions of the Indenture; (ii) so long as no Default shall have occurred and
be continuing, the purchase, redemption, retirement or other acquisition of any
shares of Capital Stock of RCN (A) in exchange for or conversion into or (B) out
of the net cash proceeds of the substantially concurrent issue and sale (other
than to a Restricted Subsidiary or to a Restricted Affiliate) of shares of
Capital Stock of RCN (other than Disqualified Stock); provided that any such net
cash proceeds pursuant to the immediately preceding subclause (B) are excluded
from clause (iii)(b) of the preceding paragraph; (iii) so long as no Default
shall have occurred and be continuing, the purchase, redemption, defeasance or
other acquisition or retirement for value of Subordinated Indebtedness made by
exchange for (including any such exchange pursuant to the exercise of a
conversion right or privilege in which cash is paid in lieu of fractional shares
or scrip), or out of the net cash proceeds of, a substantially concurrent issue
or sale (other than to a Restricted Subsidiary or to a Restricted Affiliate) of
(A) Capital Stock (other than Disqualified Stock) of RCN; provided that any such
net cash proceeds, to the extent so used, are excluded from clause (iii)(b) of
the preceding paragraph, and/or (B) other Subordinated Indebtedness, having an
Average Life to Stated Maturity that is equal to or greater than the Average
Life to Stated Maturity of the Subordinated Indebtedness being purchased,
redeemed, defeased or otherwise acquired or retired; (iv) so long as no Default
shall have occurred and be continuing, any Investment constituting a Restricted
Payment made by RCN or any Restricted Subsidiary in any Restricted Affiliate to
fund the capital requirements for financing or supporting a Permitted Business
of such Restricted Affiliate; (v) so long as no Default shall have occurred and
be continuing, Investments constituting a Restricted Payment made by RCN or any
Restricted Subsidiary in any person (including any Unrestricted Subsidiary or a
Restricted Affiliate) in an amount not to exceed $10 million in the aggregate at
any time outstanding; (vi) so long as no Default shall have occurred and be
continuing, the making of a direct or indirect Investment constituting a
Restricted Payment out of the proceeds of the issue or sale (other than to a
Subsidiary or to a Restricted Affiliate) of Capital Stock (other than
Disqualified Stock) of RCN; provided that any such net cash proceeds are
excluded from clause (iii)(b) of the preceding paragraph; or (vii) so long as no
Default shall have occurred and be continuing, any Investment constituting a
Restricted Payment made in Megacable S.A. de C.V. not to exceed $20 million in
the aggregate at any time outstanding. Restricted Payments of the type set forth
in the preceding clauses (v) and (vii) shall be included in making the
determination of available amounts under clause (iii) of the preceding paragraph
to the extent they are outstanding.

     In no event shall a Restricted Payment made on the basis of consolidated
financial statements prepared in good faith in accordance with GAAP be subject
to rescission or constitute a Default by reason of any requisite subsequent
restatement of such financial statements which would have made such Restricted
Payment prohibited at the time that it was made.

     Limitation on Business. The Indenture provides that RCN will not, and will
not permit any of the Restricted Subsidiaries or Restricted Affiliates to,
engage in a business which is not substantially a Permitted Business.

     Limitation on Liens Securing Certain Indebtedness. The Indenture provides
that RCN will not, and will not permit any Restricted Subsidiary or Restricted
Affiliate to, create, incur, assume or suffer to exist any Liens of any kind
against or upon any property or assets of RCN or any Restricted Subsidiary or
Restricted Affiliate, whether now owned or hereafter acquired, or any proceeds
therefrom, which secure either (x) Subordinated Indebtedness unless the Notes
issued thereunder are secured by a Lien on such property, assets or proceeds
that is senior in priority to the Liens securing such Subordinated Indebtedness
or (y) Senior Debt Securities unless the Notes issued thereunder are equally and
ratably secured with the Liens securing such Senior Debt Securities other than
the Lien on the escrow account in favor of the escrow agent and the trustee
under the indenture governing the 10% Senior Notes.

     Limitation on Certain Guarantees and Indebtedness of Restricted
Subsidiaries and Restricted Affiliates. The Indenture provides that RCN will not
permit any Restricted Subsidiary or Restricted Affiliate directly or indirectly,
to assume, guarantee or in any other manner become liable, whether as issuer,
guarantor or co-obligor, with respect to (i) any Subordinated Indebtedness or
(ii) any Senior Debt Securities, unless, in each case, such Restricted
Subsidiary or Restricted Affiliate, as the case may be, simultaneously executes
and delivers a supplemental indenture providing for the guarantee of payment of
the Notes by such Restricted Subsidiary or Restricted Affiliate, as the case may
be, on a basis senior to any such Subordinated Indebtedness or pari passu with
any such Senior Debt Securities, as the case may be. Each guarantee of the Notes
created pursuant to such provisions is referred to as a "Guarantee" and the
issuer of each such Guarantee, so long as the Guarantee remains outstanding, is
referred to as a "Guarantor."

     Notwithstanding the foregoing, in the event of the unconditional release of
any Guarantor from its obligations in respect of the Indebtedness which gave
rise to the requirement that a Guarantee be given, such Guarantor shall be
released from all obligations under its Guarantee. In addition, upon any sale or
disposition (by merger or otherwise) of any Guarantor by RCN or a Restricted
Subsidiary to any person that is not an Affiliate of RCN or any of the
Restricted Subsidiaries which is otherwise in compliance with the terms of the
Indenture and as a result of which such Guarantor ceases to be a Restricted
Subsidiary of RCN, such Guarantor will be deemed to be automatically and
unconditionally released from all obligations under its Guarantee; provided that
each such Guarantor is sold or disposed of in accordance with the "Disposition
of Proceeds of Asset Sales" covenant.

     Change of Control. Upon the occurrence of a Change of Control (the date of
such occurrence being the "Change of Control Date"), RCN shall make an offer to
purchase (the "Change of Control Offer"), on a business day (the "Change of
Control Payment Date") not later than 60 days following the Change of Control
Date, all Notes then outstanding at a purchase price equal to 101% of the
Accreted Value thereof plus accrued and unpaid interest, if any, to any Change
of Control Payment Date. Notice of a Change of Control Offer shall be given to
holders of Notes, not less than 25 days nor more than 45 days before the Change
of Control Payment Date. The Change of Control Offer is required to remain open
for at least 20 business days and until the close of business on the Change of
Control Payment Date.

     If a Change of Control Offer is made, there can be no assurance that RCN
will have available funds sufficient to pay for all of the Notes that might be
delivered by holders of Notes seeking to accept the Change of Control Offer. RCN
shall not be required to make a Change of Control Offer following a Change of
Control if a third party makes the Change of Control Offer in the manner, at the
times and otherwise in compliance with the requirements applicable to a Change
of Control Offer made by RCN and purchases all Notes validly tendered and not
withdrawn under such Change of Control Offer.

     If RCN is required to make a Change of Control Offer, RCN will comply with
all applicable tender offer laws and regulations, including, to the extent
applicable, Section 14(e) and Rule 14e-1 under the Exchange Act, and any other
applicable securities laws and regulations.

     Limitation on Dividend and Other Payment Restrictions Affecting Restricted
Subsidiaries or Restricted Affiliates. The Indenture provides that RCN will not,
and will not permit any Restricted Subsidiary or Restricted Affiliate to,
directly or indirectly, create or otherwise enter into or cause to become
effective any consensual encumbrance or consensual restriction of any kind on
the ability of any Restricted Subsidiary or Restricted Affiliate to (a) pay
dividends, in cash or otherwise, or make any other distributions on its Capital
Stock or any other interest or participation in, or measured by, its profits to
the extent owned by RCN or any Restricted Subsidiary or Restricted Affiliate,
(b) pay any Indebtedness owed to RCN or any Restricted Subsidiary or Restricted
Affiliate, (c) make any Investment in RCN or any Restricted Subsidiary or
Restricted Affiliate or (d) transfer any of its properties or assets to RCN or
to any Restricted Subsidiary or Restricted Affiliate, except for (i) any
encumbrance or restriction in existence on the Issue Date, (ii) customary
non-assignment provisions, (iii) any encumbrance or restriction pertaining to an
asset subject to a Lien to the extent set forth in the security documentation
governing such Lien, (iv) any encumbrance or restriction applicable to a
Restricted Subsidiary or Restricted Affiliate at the time that it becomes a
Restricted Subsidiary or Restricted Affiliate that is not created in
contemplation thereof, (v) any encumbrance or restriction existing under any
agreement that refinances or replaces an agreement containing a restriction
permitted by clause (iv) above; provided that the terms and conditions of any
such encumbrance or restriction are not materially less favorable to the holders
of Notes than those under or pursuant to the agreement being replaced or the
agreement evidencing the Indebtedness refinanced, (vi) any encumbrance or
restriction imposed upon a Restricted Subsidiary or Restricted Affiliate
pursuant to an agreement which has been entered into for the sale or disposition
of all or substantially all of the Capital Stock or assets of such Restricted
Subsidiary or Restricted Affiliate or any Asset Sale to the extent limited to
the Capital Stock or assets in question, and (vii) any customary encumbrance or
restriction applicable to a Restricted Subsidiary or Restricted Affiliate that
is contained in an agreement or instrument governing or relating to Indebtedness
contained in any Permitted Credit Facility; provided that (subject to customary
net worth, leverage, invested capital and other financial covenants) the
provisions of such agreement permit the payment of interest and principal and
mandatory repurchases pursuant to the terms of the Indenture and the Notes and
other indebtedness that is solely an obligation of RCN; provided, further, that
such agreement may contain customary covenants regarding the merger of or sale
of all or any substantial part of the assets of RCN or any Restricted Subsidiary
or Restricted Affiliate, customary restrictions on transactions with affiliates,
and customary subordination provisions governing indebtedness owed to RCN or any
Restricted Subsidiary or Restricted Affiliate.

     Disposition of Proceeds of Asset Sales. The Indenture provides that RCN
will not, and will not permit any Restricted Subsidiary or Restricted Affiliate
to, make any Asset Sale unless (a) RCN or such Restricted Subsidiary or
Restricted Affiliate, as the case may be, receives consideration at the time of
such Asset Sale at least equal to the Fair Market Value of the shares or assets
sold or otherwise disposed of and (b) at least 75% of such consideration
consists of cash or Cash Equivalents; provided that the amount of any
liabilities (other than Subordinated Indebtedness or Indebtedness of a
Restricted Subsidiary that would not constitute Restricted Subsidiary
Indebtedness) that are assumed by the transferee of any such assets pursuant to
an agreement that unconditionally releases RCN or such Restricted Subsidiary or
Restricted Affiliate, as the case may be, from further liability shall be
treated as cash for purposes of this covenant. RCN or the applicable Restricted
Subsidiary, as the case may be, may (i) apply the Net Cash Proceeds from any
such Asset Sale by RCN or a Restricted Subsidiary and the Net Cash Proceeds of
any Asset Sale by a Restricted Affiliate to the extent distributed to RCN or a
Restricted Subsidiary within 365 days of the receipt thereof to repay an amount
of Indebtedness (other than Subordinated Indebtedness) of RCN in an amount not
exceeding the Other Senior Debt Pro Rata Share and elect to permanently reduce
the amount of the commitments thereunder by the amount of the Indebtedness so
repaid, (ii) apply the Net Cash Proceeds from any such Asset Sale by RCN or a
Restricted Subsidiary and the Net Cash Proceeds of any Asset Sale by a
Restricted Affiliate to the extent distributed to RCN or a Restricted Subsidiary
to repay any Restricted Subsidiary Indebtedness and elect to permanently reduce
the commitments thereunder by the amount of the Indebtedness so repaid or (iii)
apply the Net Cash Proceeds from any Asset Sale by RCN or a Restricted
Subsidiary and the Net Cash Proceeds of any Asset Sale by a Restricted Affiliate
to the extent distributed to RCN or a Restricted Subsidiary within 365 days
thereof, to an investment in properties and assets that will be used in a
Permitted Business (or in Capital Stock and other securities of any person that
will become a Restricted Subsidiary or Restricted Affiliate as a result of such
investment to the extent such person owns properties and assets that will be
used in a Permitted Business) of RCN or any Restricted Subsidiary ("Replacement
Assets"). Notwithstanding anything herein to the contrary, in the event of any
Asset Sale of all or substantially all of the properties or assets of any
Restricted Affiliate Group, whether in a single transaction or series of related
transactions, the Restricted Affiliate Group shall be required to distribute the
Net Cash Proceeds therefrom, after providing for all Indebtedness and other
liabilities of such Restricted Affiliate Group, to RCN or a Restricted
Subsidiary and the Other Partner on a pro rata basis in accordance with their
respective equity interests. Any Net Cash Proceeds from any Asset Sale that are
neither used to repay, and permanently reduce the commitments under, any
Restricted Subsidiary Indebtedness as set forth in clause (ii) of the preceding
sentence or invested in Replacement Assets within the 365-day period as set
forth in clause (iii) shall constitute "Excess Proceeds." Any Excess Proceeds
not used as set forth in clause (i) of the second preceding sentence shall
constitute "Offer Excess Proceeds" subject to disposition as provided below.

     When the aggregate amount of Offer Excess Proceeds equals or exceeds $10
million, RCN shall make an offer to purchase (an "Asset Sale Offer"), from all
holders of Notes issued under the Indenture, that aggregate principal amount of
Notes as can be purchased by application of such Offer Excess Proceeds at a
price in cash equal to 100% of the outstanding Accreted Value thereof plus
accrued and unpaid interest, if any, to the purchase date. Each Asset Sale Offer
shall remain open for a period of 20 business days or such longer period as may
be required by law. To the extent that the aggregate purchase price for the
Notes tendered pursuant to an Asset Sale Offer is less than the Offer Excess
Proceeds, RCN or any Restricted Subsidiary may use such deficiency for general
corporate purposes. If the aggregate purchase price for the Notes validly
tendered and not withdrawn by holders thereof exceeds the amount of Notes which
can be purchased with the Offer Excess Proceeds, Notes to be purchased will be
selected on a pro rata basis. Upon completion of such Asset Sale Offer, the
amount of Offer Excess Proceeds shall be reset to zero.

     Notwithstanding the two immediately preceding paragraphs, RCN, the
Restricted Subsidiaries and the Restricted Affiliates will be permitted to
consummate an Asset Sale without complying with such paragraphs to the extent
(i) at least 75% of the consideration of such Asset Sale constitutes Replacement
Assets, cash or Cash Equivalents (including obligations deemed to be cash under
this covenant) and (ii) such Asset Sale is for Fair Market Value; provided that
any consideration constituting (or deemed to constitute) cash or Cash
Equivalents received by RCN, any of the Restricted Subsidiaries or any of the
Restricted Affiliates in connection with any Asset Sale permitted to be
consummated under this paragraph shall constitute Net Cash Proceeds subject to
the provisions of the two preceding paragraphs.

     If RCN is required to make an Asset Sale Offer, RCN will comply with all
applicable tender offer rules, including, to the extent applicable, Section
14(e) and Rule 14e-1 under the Exchange Act, and any other applicable securities
laws and regulations.

     Limitation on Issuances and Sales of Preferred Stock by Restricted
Subsidiaries and Restricted Affiliates. The Indenture provides that RCN (i) will
not permit any Restricted Subsidiary to issue any Preferred Stock (other than to
RCN or a Restricted Subsidiary) and (ii) will not permit any person (other than
RCN or a Restricted Subsidiary) to own any Preferred Stock of any Restricted
Subsidiary. In addition, RCN (i) will not permit any Restricted Affiliate to
issue any Preferred Stock (other than (x) to RCN or a Restricted Subsidiary or
(y) to the holders of Common Stock in such Restricted Affiliate on a pro rata
basis based upon their ownership of Common Stock) or (ii) will not permit any
person not referred to in the preceding parenthetical of clause (i) of this
sentence to own any Preferred Stock of any Restricted Affiliate.

     Limitation on Transactions with Affiliates. The Indenture provides that RCN
will not, and will not permit, cause or suffer any Restricted Subsidiary to,
conduct any business or enter into any transaction (or series of related
transactions which are similar or part of a common plan) with or for the benefit
of any of their respective Affiliates or any beneficial holder of 10% or more of
the Common Stock of RCN or any officer or director of RCN (each, an "Affiliate
Transaction"), unless the terms of the Affiliate Transaction are set forth in
writing, and are fair and reasonable to RCN or such Restricted Subsidiary, as
the case may be. Each Affiliate Transaction involving aggregate payments or
other Fair Market Value in excess of $5 million shall be approved by a majority
of the Board, such approval to be evidenced by a Board Resolution stating that
the Board has determined that such transaction or transactions comply with the
foregoing provisions. In addition to the foregoing, each Affiliate Transaction
involving aggregate consideration of $10 million or more shall be approved by a
majority of the Disinterested Directors; provided that, in lieu of such approval
by the Disinterested Directors, RCN may obtain a written opinion from an
Independent Financial Advisor stating that the terms of such Affiliate
Transaction to RCN or the Restricted Subsidiary, as the case may be, are fair
from a financial point of view. In addition, the Indenture provides that a
Restricted Affiliate will not enter into any transaction (or series of related
transactions which are similar or part of a common plan) with or for the benefit
of the Other Partner, unless the terms of such transaction or transactions are
in writing, and are fair and reasonable to such Restricted Affiliate. For
purposes of this covenant, any Affiliate Transaction approved by a majority of
the Disinterested Directors or as to which a written opinion has been obtained
from an Independent Financial Advisor, on the basis set forth in the preceding
sentence, shall be deemed to be on terms that are fair and reasonable to RCN and
the Restricted Subsidiaries, as the case may be, and therefore shall be
permitted under this covenant.

     Notwithstanding the foregoing, the restrictions set forth in this covenant
shall not apply to (i) transactions with or among, or solely for the benefit of,
RCN and/or any of the Restricted Subsidiaries, (ii) transactions pursuant to
agreements and arrangements existing on the Issue Date, (iii) transactions among
any of RCN or the Restricted Subsidiaries, on the one hand, and any of the
Restricted Affiliates, on the other hand, provided that such transactions are in
the ordinary course of business and are related to or in furtherance of a
Permitted Business, (iv) dividends paid by RCN pursuant to and in compliance
with the covenant "Limitation on Restricted Payments," (v) customary directors'
fees, indemnification and similar arrangements, consulting fees, employee
salaries bonuses, employment agreements and arrangements, compensation or
employee benefit arrangements or legal fees and (vi) grants of customary
registration rights with respect to securities of RCN.

     Reports. The Indenture provides that, whether or not RCN has a class of
securities registered under the Exchange Act, RCN shall furnish without cost to
each holder of record of Notes issued thereunder (in sufficient quantities for
distribution to beneficial holders) and file with the Trustee and the
Commission, (i) within the applicable time period required under the Exchange
Act, after the end of each fiscal year of RCN, the information required by Form
10-K (or any successor form thereto) under the Exchange Act with respect to such
period, (ii) within the applicable time period required under the Exchange Act
after the end of each of the first three fiscal quarters of each fiscal year of
RCN, the information required by Form 10-Q (or any successor form thereto) under
the Exchange Act with respect to such period and (iii) any current reports on
Form 8-K (or any successor forms) required to be filed under the Exchange Act.

     Designations of Unrestricted Subsidiaries. The Indenture provides that RCN
will not designate any Subsidiary of RCN (other than a newly created Subsidiary
in which no Investment has previously been made) as an "Unrestricted Subsidiary"
under the Indenture (a "Designation") unless:

      (a) no Default shall have occurred and be continuing at the time of or
     after giving effect to such Designation;

      (b) except in the case of a Permitted Investment or an Investment made
     pursuant to clause (iii) or (iv) of the second paragraph of the covenant
     "Limitation on Restricted Payments," immediately after giving effect to
     such Designation, RCN would be able to incur $1.00 of Indebtedness under
     clause (A)(X) of the proviso of the covenant "Limitation on Additional
     Indebtedness"; and

      (c) RCN would not be prohibited under the Indenture from making an
     Investment at the time of such Designation (assuming the effectiveness of
     such Designation) in an amount (the "US Designation Amount") equal to the
     Fair Market Value of the net Investment of RCN or any other Restricted
     Subsidiary in such Subsidiary on such date. In the event of any such
     Designation, RCN shall be deemed to have made an Investment constituting a
     Restricted Payment pursuant to the covenant "Limitation on Restricted
     Payments" for all purposes of the Indenture in the US Designation Amount.
     The Indenture further provides that neither RCN nor any Restricted
     Subsidiary shall at any time (x) provide a guarantee of, or similar credit
     support to, any Indebtedness of any Unrestricted Subsidiary (including any
     undertaking, agreement or instrument evidencing such Indebtedness);
     provided that RCN may pledge Capital Stock or Indebtedness of any
     Unrestricted Subsidiary on a nonrecourse basis such that the pledgee has no
     claim whatsoever against RCN other than to obtain such pledged property,
     (y) be directly or indirectly liable for any Indebtedness of any
     Unrestricted Subsidiary or (z) be directly or indirectly liable for any
     other Indebtedness which provides that the holder thereof may (upon notice,
     lapse of time or both) declare a default thereon (or cause the payment
     thereof to be accelerated or payable prior to its final scheduled maturity)
     upon the occurrence of a default with respect to any other Indebtedness
     that is Indebtedness of an Unrestricted Subsidiary (including any
     corresponding right to take enforcement action against such Unrestricted
     Subsidiary), except in the case of clause (x) or (y) to the extent
     permitted under the covenants "Limitation on Restricted Payments" and
     "Limitation on Transactions with Affiliates."

     The Indenture further provides that RCN will not revoke any Designation of
a Subsidiary as an Unrestricted Subsidiary (a "Revocation") unless:

      (a) no Default shall have occurred and be continuing at the time of and
     after giving effect to such Revocation; and

      (b) all Liens and Indebtedness of such Unrestricted Subsidiary outstanding
     immediately following such Revocation would, if incurred at such time, have
     been permitted to be incurred for all purposes of the Indenture.

     All Designations and Revocations must be evidenced by Board Resolutions
delivered to the Trustee certifying compliance with the foregoing provisions.

     Designations of Restricted Affiliates. The Indenture provides that RCN will
not designate any Joint Venture (other than a newly created Joint Venture in
which no Investment has previously been made) and each of its Subsidiaries as a
"Restricted Affiliate" under the Indenture (a "JV Designation") unless:

      (a) no Default shall have occurred and be continuing at the time of and
     after giving effect to such JV Designation; and

      (b) all Liens and Indebtedness of such Joint Venture outstanding
     immediately following such JV Designation would, if incurred at such time,
     have been permitted to be incurred for all purposes of the Indenture.

     Notwithstanding the foregoing, the BECO Joint Venture and the Starpower
Joint Venture shall initially constitute Restricted Affiliates at the Issue
Date. RCN and the Restricted Subsidiaries shall at all times maintain a
Restricted Affiliate so that it qualifies as a Joint Venture under clauses (a)
and (b) of the definition thereof, unless either (1) RCN is able to, and does in
fact, make an effective JV Revocation under the provisions set forth below at
the time of such event or (2) the Restricted Affiliate ceases to qualify as a
Joint Venture by reason of an Asset Sale by RCN or a Restricted Subsidiary of
all of RCN's or such Restricted Subsidiary's interest in the Capital Stock of
such Restricted Affiliate to any person other than RCN or a Restricted
Subsidiary or any of their respective Affiliates, which, in the case of this
clause (2), shall be deemed an effective JV Revocation.

     The Indenture further provides that RCN will not revoke any JV Designation
of a Joint Venture as a Restricted Affiliate (a "JV Revocation") unless:

      (a) no Default shall have occurred and be continuing at the time of or
     after giving effect to such JV Revocation;

      (b) except in the case of a Permitted Investment or an Investment made
     pursuant to clause (v) or (vi) of the second paragraph of the covenant
     "Limitation on Restricted Payments" and except in the case in which the
     Restricted Affiliate will become a Restricted Subsidiary, immediately after
     giving effect to such JV Revocation, RCN would be able to incur $1.00 of
     Indebtedness under the proviso of clause (A)(X) of the covenant "Limitation
     on Additional Indebtedness"; and

      (c) RCN would not be prohibited under the Indenture from making an
     Investment at the time of such JV Revocation (assuming the effectiveness of
     such JV Revocation) in an amount (the "JV Revocation Amount") equal to the
     Fair Market Value of the net Investment of RCN or any other Restricted
     Subsidiary in such Restricted Subsidiary on such date. In the event of any
     such JV Revocation, except in the case in which the Restricted Affiliate
     will become a Restricted Subsidiary, RCN shall be deemed to have made an
     Investment constituting a Restricted Payment pursuant to the covenant
     "Limitation on Restricted Payments" for all purposes of the Indenture in
     the JV Revocation Amount.

     All JV Designations and JV Revocations must be evidenced by Board
Resolutions delivered to the Trustee certifying compliance with the foregoing
provisions.

Consolidation, Merger, Sale of Assets, Etc.

     The Indenture provides that RCN will not (i) consolidate or combine with or
merge with or into or, directly or indirectly, sell, assign, convey, lease,
transfer or otherwise dispose of all or substantially all of its properties and
assets to any person or persons in a single transaction or through a series of
transactions, or (ii) permit any of the Restricted Subsidiaries to enter into
any such transaction or series of transactions if it would result in the
disposition of all or substantially all of the properties or assets of RCN and
the Restricted Subsidiaries on a consolidated basis, unless, in the case of
either (i) or (ii), (a) RCN shall be the continuing person or, if RCN is not the
continuing person, the resulting, surviving or transferee person (the "surviving
entity") shall be a company organized and existing under the laws of the United
States or any State or territory thereof; (b) the surviving entity shall
expressly assume all of the obligations of RCN under the Notes and the
Indenture, and shall, if required by law to effectuate such assumption, execute
a supplemental indenture to effect such assumption which supplemental indenture
shall be delivered to the Trustee and shall be in form and substance reasonably
satisfactory to the Trustee; (c) immediately after giving effect to such
transaction or series of transactions on a pro forma basis (including, without
limitation, any Indebtedness incurred or anticipated to be incurred in
connection with or in respect of such transaction or series of transactions),
RCN or the surviving entity (assuming such surviving entity's assumption of RCN
obligations under the Notes and Indenture), as the case may be, would be able to
incur $1.00 of Indebtedness under clause (A)(X) of the proviso of the covenant
"Limitation on Additional Indebtedness"; (d) immediately after giving effect to
such transaction or series of transactions on a pro forma basis (including,
without limitation, any Indebtedness incurred or anticipated to be incurred in
connection with or in respect of such transaction or series of transactions), no
Default shall have occurred and be continuing; and (e) RCN or the surviving
entity, as the case may be, shall have delivered to the Trustee an Officers'
Certificate stating that such transaction or series of transactions, and, if a
supplemental indenture, is required in connection with such transaction or
series of transactions to effectuate such assumption, such supplemental
indenture complies with this covenant and that all conditions precedent in the
Indenture relating to the transaction or series of transactions have been
satisfied.

     Upon any consolidation or merger or any sale, assignment, conveyance,
lease, transfer or other disposition of all or substantially all of the assets
of RCN in accordance with the foregoing in which RCN or the Restricted
Subsidiary, as the case may be, is not the continuing corporation, the successor
corporation formed by such a consolidation or into which RCN or such Restricted
Subsidiary is merged or to which such transfer is made will succeed to, and be
substituted for, and may exercise every right and power of, RCN or such
Restricted Subsidiary, as the case may be, under the Indenture with the same
effect as if such successor corporation had been named as RCN or such Restricted
Subsidiary therein; and thereafter, except in the case of (i) any lease or (ii)
any sale, assignment, conveyance, transfer, lease or other disposition to a
Restricted Subsidiary of RCN, RCN shall be discharged from all obligations and
covenants under the Indenture and the Notes issued thereunder.

     The Indenture provides that for all purposes of the Indenture and the Notes
(including the provision of this covenant and the covenants "Limitation on
Additional Indebtedness," "Limitation on Restricted Payments" and "Limitation on
Liens"), Subsidiaries of any surviving entity will, upon such transaction or
series of related transactions, become Restricted Subsidiaries or Unrestricted
Subsidiaries as provided pursuant to the covenant "Limitation on Designations of
Unrestricted Subsidiaries" and all Indebtedness, and all Liens on property or
assets, of RCN and the Restricted Subsidiaries in existence immediately prior to
such transaction or series of related transactions will be deemed to have been
incurred upon such transaction or series of related transactions.

Events of Default

     The following are "Events of Default" under the Indenture:

      (i) default in the payment of interest on the Notes when it becomes due
     and payable and continuance of such default for a period of 30 days or
     more; or

     (ii) default in the payment of the principal of, or premium, if any, on the
     Notes when due; or

    (iii) default in the performance, or breach, of any covenant described under
     "--Certain Covenants--Change of Control," "--Disposition of Proceeds of
     Asset Sales" or "--Consolidation, Merger, Sale of Assets, Etc."; or

     (iv) default in the performance, or breach, of any covenant in the
     Indenture (other than defaults specified in clause (i), (ii) or (iii)
     above) and continuance of such default or breach for a period of 30 days or
     more after written notice to RCN by the Trustee or to RCN and the Trustee
     by the holders of at least 25% in Accreted Value of the outstanding Notes
     (when such notice is deemed received in accordance with the Indenture); or

      (v) failure to perform any term, covenant, condition or provision of one
     or more classes or issues of Indebtedness in an aggregate principal amount
     of $10 million or more under which RCN or a Material Restricted Subsidiary
     is obligated, and either (a) such Indebtedness is already due and payable
     in full or (b) such failure results in the acceleration of the maturity of
     such Indebtedness; or

     (vi) any holder of at least $10 million in aggregate principal amount of
     Indebtedness of RCN or any Material Restricted Subsidiary shall commence
     judicial proceedings or take any other action to foreclose upon, or dispose
     of, assets of RCN or any Material Restricted Subsidiary having an aggregate
     Fair Market Value, individually or in the aggregate, of $10 million or more
     or shall have exercised any right under applicable law or applicable
     security documents to take ownership of any such assets in lieu of
     foreclosure; provided that, in any such case, RCN or any Material
     Restricted Subsidiary shall not have obtained, prior to any such
     foreclosure or disposition of assets, a stay of all such actions that
     remains in effect; or

     (vii) one or more final non-appealable judgments, orders or decrees for the
     payment of money of $10 million or more, either individually or in the
     aggregate, shall be entered against RCN or any Material Restricted
     Subsidiary or any of their respective properties and shall not be
     discharged and there shall have been a period of 60 days or more during
     which a stay of enforcement of such judgment or order, by reason of pending
     appeal or otherwise, shall not be in effect; or

     (viii) certain events of bankruptcy, insolvency, reorganization,
     administration or similar proceedings with respect to RCN or any Material
     Restricted Subsidiary shall have occurred.

     If an Event of Default (other than an Event of Default specified in clause
(viii) with respect to RCN) under the Indenture occurs and is continuing, then
the Trustee thereunder or the holders of at least 25% in Accreted Value of the
outstanding Notes may by written notice, and the Trustee upon request of the
holders of not less than 25% in Accreted Value of the outstanding Notes shall,
declare the Default Amount of the outstanding Notes issued thereunder to be due
and payable immediately, together with all accrued and unpaid interest and
premium, if any, thereon. Upon any such declaration, the Default Amount shall
become due and payable immediately. If an Event of Default under the Indenture
specified in clause (viii) with respect to RCN occurs and is continuing, then
the Default Amount will ipso facto become and be immediately due and payable
without any declaration or other act on the part of the Trustee or any holder.

     After a declaration of acceleration or any ipso facto acceleration pursuant
to clause (viii) under the Indenture, the holders of a majority in Accreted
Value of outstanding Notes may, by notice to the applicable Trustee, rescind
such declaration of acceleration and its consequences if all existing Events of
Default, other than nonpayment of the principal of, and accrued and unpaid
interest on, such Notes that has become due solely as a result of such
acceleration, have been cured or waived and if the rescission of acceleration
would not conflict with any judgment or decree. The holders of a majority in
Accreted Value of the outstanding Notes also have the right to waive past
defaults, except a default in the payment of the principal of, or any interest
on, any outstanding Note, or in respect of a covenant or a provision that cannot
be modified or amended without the consent of all holders of the Notes.

     No holder of any of the Notes issued under the Indenture has any right to
institute any proceeding with respect to such Indenture or any remedy
thereunder, unless the holders of at least 25% in Accreted Value of the
outstanding Notes have made written request, and offered reasonable indemnity,
to the Trustee to institute such proceeding as Trustee, the Trustee has failed
to institute such proceeding within 60 days after receipt of such notice and the
Trustee has not within such 60-day period received directions inconsistent with
such written request by holders of a majority in Accreted Value of the
outstanding Notes. Such limitations do not apply, however, to a suit instituted
by a holder of a Note for the enforcement of the payment of the principal of,
premium, if any, or any accrued and unpaid interest on, such Note on or after
the respective due dates expressed in such Note.

     During the existence of an Event of Default under the Indenture, the
Trustee is required to exercise such rights and powers vested in it under such
Indenture and use the same degree of care and skill in its exercise thereof as a
prudent person would exercise under the circumstances in the conduct of such
person's own affairs. Subject to the provisions of the Indenture relating to the
duties of the Trustee, if an Event of Default shall occur and be continuing, the
Trustee is not under any obligation to exercise any of its rights or powers
under the Indenture at the request or direction of any of the holders unless
such holders shall have offered to the Trustee reasonable security or indemnity.
Subject to certain provisions concerning the rights of the Trustee, the holders
of a majority in Accreted Value of the outstanding Notes have the right to
direct the time, method and place of conducting any proceeding for any remedy
available to the Trustee, or exercising any trust, or power conferred on the
Trustee.

     The Indenture provides that the Trustee will, within 45 days after the
occurrence of any Default, give to the holders of the Notes notice of such
Default known to it, unless such Default shall have been cured or waived;
provided that, except in the case of a Default in payment of principal of or
premium, if any, on any Note when due or in the case of any Default in the
payment of any interest on the Notes or in the case of any Default arising from
the occurrence of any Change of Control, the Trustee shall be protected in
withholding such notice if it determines in good faith that the withholding of
such notice is in the interest of such holders.

     RCN is required to furnish to the Trustee annually a statement as to
compliance with all conditions and covenants under the Indenture.

Satisfaction and Discharge of the Indenture; Defeasance

     RCN may terminate its obligations under the Indenture, when (1) either: (A)
all Notes issued thereunder that have been theretofore authenticated and
delivered have been delivered to the Trustee for cancellation, or (B) all such
Notes issued thereunder that have not theretofore delivered to the Trustee for
cancellation will become due and payable (a "Discharge") under irrevocable
arrangements satisfactory to the Trustee for the giving of notice of redemption
by such Trustee in the name, and at the expense, of RCN, and RCN has irrevocably
deposited or caused to be deposited with such Trustee funds in an amount
sufficient to pay and discharge the entire indebtedness on such issue of Notes,
not theretofore delivered to the Trustee for cancellation, for principal of,
premium, if any, on and interest to the date of deposit or maturity or date of
redemption; (2) RCN has paid or caused to be paid all other sums then due and
payable under the Indenture by RCN; and (3) RCN has delivered to the Trustee an
officers' certificate and an opinion of counsel, each stating that all
conditions precedent under the Indenture relating to the satisfaction and
discharge of the Indenture have been complied with.

     RCN may elect, at its option, to have its obligations under the Indenture
discharged with respect to the outstanding Notes ("legal defeasance"). Such
defeasance means that RCN will be deemed to have paid and discharged the entire
indebtedness represented by the outstanding Notes under the Indenture, except
for (1) the rights of holders of Notes to receive payments in respect of the
principal of and any premium and interest on the Notes when payments are due,
(2) RCN's obligations with respect to the Notes concerning issuing temporary
Notes, registration of transfer of Notes, mutilated, destroyed, lost or stolen
Notes and the maintenance of an office or agency for payment and money for
security payments held in trust, (3) the rights, powers, trusts, duties and
immunities of the Trustee, and (4) the defeasance provisions of the Indenture.
In addition, RCN may elect, at its option, to have its obligations released with
respect to certain covenants in the Indenture, including covenants relating to
Asset Sales and Changes of Control ("covenant defeasance"), and any omission to
comply with such obligation shall not constitute a Default or an Event of
Default with respect to the Notes under such Indenture. In the event covenant
defeasance occurs, certain events (not including non-payment, bankruptcy and
insolvency events) described under "Events of Default" will no longer constitute
an Event of Default with respect to such Notes.

     In order to exercise either legal defeasance or covenant defeasance with
respect to outstanding Notes: (1) RCN must irrevocably have deposited or caused
to be deposited with the Trustee as trust funds in trust for the purpose of
making the following payments, specifically pledged as security for, and
dedicated solely to the benefits of the holders of the Notes: (A) money in an
amount, or (B) U.S. Government Obligations which through the scheduled payment
of principal and interest in respect thereof in accordance with their terms will
provide, not later than the due date of any payment, money in an amount, or (C)
a combination thereof, in each case sufficient without reinvestment, in the
opinion of an internationally recognized firm of independent public accountants
expressed in a written certification thereof delivered to the Trustee to pay and
discharge, and which shall be applied by the Trustee to pay and discharge, the
entire Indebtedness in respect of the principal of and premium, if any, and
interest on the Notes on the maturity thereof or (if RCN has made irrevocable
arrangements satisfactory to the Trustee for the giving of notice of redemption
by the Trustee in the name and at the expense of RCN) the redemption date
thereof, as the case may be, in accordance with the terms of such Indenture and
Notes; (2) in the case of legal defeasance under the Indenture, RCN shall have
delivered to the Trustee an opinion of counsel stating that, under then
applicable Federal income tax law, the holders of the Notes will not recognize
gain or loss for federal income tax purposes as a result of the deposit,
defeasance and discharge to be effected with respect to the Notes and will be
subject to federal income tax on the same amount, in the same manner and at the
same times as would be the case if such deposit, defeasance and discharge were
not to occur; (3) in the case of covenant defeasance under the Indenture, RCN
shall have delivered to the Trustee an opinion of counsel to the effect that the
holders of such outstanding Notes will not recognize gain or loss for U.S.
federal income tax purposes as a result of the deposit and covenant defeasance
to be effected with respect to the Notes and will be subject to U.S. federal
income tax on the same amount, in the same manner and at the same times as would
be the case if such deposit and covenant defeasance were not to occur; (4) no
Default with respect to the outstanding Notes shall have occurred and be
continuing at the time of such deposit after giving effect thereto or, in the
case of legal defeasance, no Default relating to bankruptcy or insolvency shall
have occurred and be continuing at any time on or prior to the 91st day after
the date of such deposit (it being understood that this condition shall not be
deemed satisfied until after such 91st day); (5) such legal defeasance or
covenant defeasance shall not cause the applicable Trustee to have a conflicting
interest within the meaning of the Trust Indenture Act (assuming all Notes were
in default within the meaning of such Act); (6) such defeasance or covenant
defeasance shall not result in a breach or violation of, or constitute a default
under, any other agreement or instrument to which RCN is a party or by which it
is bound; (7) such legal defeasance or covenant defeasance shall not result in
the trust arising from such deposit constituting an investment company within
the meaning of the Investment Company Act of 1940, as amended, unless such trust
shall be registered under such Act or exempt from registration thereunder; and
(8) RCN shall have delivered to the Trustee an officers' certificate and an
opinion of counsel stating that all conditions precedent with respect to such
defeasance or covenant defeasance have been complied with.

Amendment and Waivers

     From time to time, RCN, when authorized by resolutions of the Board, and
the Trustee, without the consent of the holders of Notes, may amend, waive or
supplement the Indenture and the Notes for certain specified purposes,
including, among other things, curing ambiguities, defects or inconsistencies,
to provide for the assumption of RCN's obligations to holders of the 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 the Notes, to add Guarantors
with respect to the Notes, to secure the Notes, to maintain the qualification of
the Indenture under the Trust Indenture Act or to make any change that does not
adversely affect the rights of any holder. Other amendments and modifications of
the Indenture or the Notes issued thereunder may be made by RCN and the Trustee
with the consent of the holders of not less than a majority of the aggregate
Accreted Value of the outstanding Notes; provided that no such modification or
amendment may, without the consent of the holder of each outstanding Note
affected thereby, (i) reduce the principal amount of, or extend the fixed
maturity of the Notes, or alter or waive the redemption provisions of the Notes
(other than, subject to clause (vii) below, provisions relating to repurchase of
Notes upon the occurrence of an Asset Sale or a Change of Control) or change the
calculation of "Accreted Value", (ii) change the currency in which any Notes or
any premium or the accrued interest thereon is payable, (iii) reduce the
percentage in Accreted Value outstanding of Notes which must consent to an
amendment, supplement or waiver or consent to take any action under the

enforcement of any payment on or with respect to the Notes, (v) waive a default
in payment with respect to the Notes or any Guarantee, (vi) reduce the rate or
extend the time for payment of interest on the Notes, (vii) following the
occurrence of an Asset Sale or a Change of Control, alter the obligation to
purchase Notes as a result thereof in accordance with the Indenture or waive any
default in the performance thereof, (viii) adversely affect the ranking of the
Notes, or (ix) release any Guarantor from any of its obligations under its
Guarantee or the Indenture, except in compliance with the terms of the
Indenture.

Regarding the Trustee

     The Chase Manhattan Bank will serve as Trustee. The Indenture provides
that, except during the continuance of an Event of Default, the Trustee will
perform only such duties as are specifically set forth in the Indenture. If an
Event of Default has occurred and is continuing, the Trustee will exercise such
rights and powers vested in it under the Indenture and use the same degree of
care and skill in its exercise as a prudent person would exercise under the
circumstances in the conduct of such person's own affairs.

     The Indenture and provisions of the Trust Indenture Act incorporated by
reference therein contain limitations on the rights of the Trustee, should it
become a creditor of RCN, to obtain payment of claims in certain cases or to
realize on certain property received by it in respect of any such claims, as
security or otherwise. The Trustee is permitted to engage in other transactions;
provided that if he acquires any conflicting interest (as defined) he must
eliminate such conflict or resign.

Governing Law

     The Indenture provides that the Indenture and Notes are governed by and
construed in accordance with laws of the State of New York without giving effect
to principles of conflicts of law.

class or kind ordinarily having the power to vote for the election of directors
or other members of the governing body of such person.

     "Wholly Owned Restricted Subsidiary" means any Restricted Subsidiary in
which all of the outstanding Capital Stock is owned by RCN or another Wholly
Owned Restricted Subsidiary. For the purposes of this definition, any directors'
qualifying shares or investments by foreign nationals mandated by applicable law
shall be disregarded in determining the ownership of a Restricted Subsidiary.


                          BOOK-ENTRY; DELIVERY AND FORM

     The Old Notes were and the New Notes will be represented by one or more
permanent global note in definitive, fully registered book-entry form (the
"Global Securities") which will be registered in the name of a nominee of the
Depository Trust Company ("DTC") and deposited on behalf of purchasers of the
Notes represented thereby with a custodian for DTC for credit to the respective
accounts of the purchasers (or to such other accounts as they may direct) at
DTC.

     The Global Securities. The Company expects that pursuant to procedures
established by DTC (a) upon issuance of the Global Securities, DTC or its
custodian will credit on its internal system portions of the Global Securities
which shall be comprised of the corresponding respective amounts of the Global
Securities to the respective accounts of persons who have accounts with such
depositary and (b) ownership of the Notes will be shown on, and the transfer of
ownership thereof will be effected only through, records maintained by DTC or
its nominee (with respect to interests of Participants (as defined below) and
the records of Participants (with respect to interests of persons other than
Participants). Ownership of beneficial interests in the Global Securities will
be limited to persons who have accounts with DTC ("Participants") or persons who
hold interests through Participants.

     So long as DTC or its nominee is the registered owner or holder of any of
the Notes, DTC or such nominee will be considered the sole owner or holder of
such Notes represented by the Global Securities for all purposes under the
Indenture and under the Notes represented thereby. No beneficial owner of an
interest in the Global Securities will be able to transfer such interest except
in accordance with the applicable procedures of DTC in addition to those
provided for under the Indenture.

     Payments of the principal of, premium, if any, and interest (including
Additional Interest) on the Notes represented by the Global Securities will be
made to DTC or its nominee, as the case may be, as the registered owner thereof.
None of the Company, the Trustee or any paying agent under the Indenture will
have any responsibility or liability for any aspect of the records relating to
or payments made on account of beneficial ownership interests in the Global
Securities or for maintaining, supervising or reviewing any records relating to
such beneficial ownership interest.

     The Company expects that DTC or its nominee, upon receipt of any payment of
the principal of, premium, if any, and interest (including Additional Interest)
on the Notes represented by the Global Securities, will credit Participants'
accounts with payments in amounts proportionate to their respective beneficial
interests in the Global Securities as shown on the records of DTC or its
nominee. The Company also expects that payments by Participants to owners of
beneficial interests in the Global Securities held through such Participants
will be governed by standing instructions and customary practice as is now the
case with securities held for the accounts of customers registered in the names
of nominees for such customers. Such payment will be the responsibility of such
Participants.

     Transfers between Participants in DTC will be effected in accordance with
DTC rules and will be settled in immediately available funds. If a holder
requires physical delivery of a Certificated Security for any reason, including
to sell Notes to persons in states which require physical delivery of such
securities or to pledge such securities, such holder must transfer its interest
in the Global Securities in accordance with the normal procedures of DTC and in
accordance with the procedures set forth in the Indenture.

     Any beneficial interest in one of the Global Securities that is transferred
to a person who takes delivery in the form of an interest in the other Global
Security will, upon transfer, cease to be an interest in such Global Security
and, accordingly, will thereafter be subject to all transfer restrictions, if
any, and other procedures applicable to beneficial interests in such other
Global Security for as long as it remains such an interest.

     DTC has advised the Company that DTC will take any action permitted to be
taken by a holder of Notes (including the presentation of Notes for exchange as
described below) only at the direction of one or more Participants to whose
account the DTC interests in the Global Securities are credited and only in
respect of the aggregate principal amount of as to which such Participant or
Participants has or have given such direction. However, if there is an Event
of Default under the Indenture, DTC will exchange the Global Securities for
Certificated Securities, which it will distribute to its Participants and which
will be legended as set forth under the heading "Notice to Investors."

     DTC has advised the Company as follows: DTC is a limited purpose trust
company organized under the laws of the State of New York, a member of the
Federal Reserve System, a "clearing corporation" within the meaning of the
Uniform Commercial Code and a "clearing agency" registered pursuant to the
provisions of Section 17A of the Exchange Act. DTC was created to hold
securities for its Participants and facilitate the clearance and settlement of
securities transactions between Participants through electronic book-entry
changes in accounts of its Participants, thereby eliminating the need for
physical movement of certificates. Participants include securities brokers and
dealers, banks, trust companies and clearing corporations and certain other
organizations. Indirect access to the DTC system is available to others such as
banks, brokers, dealers and trust companies that clear through or maintain a
custodial relationship with a Participant, either directly or indirectly
("Indirect Participants").

     Although DTC is expected to follow the foregoing procedures in order to
facilitate transfers of interests in the Global Securities among Participants of
DTC, it is under no obligation to perform such procedures, and such procedures
may be discontinued at any time. Neither RCN nor either Trustee will have any
responsibility for the performance by DTC or its direct or indirect participants
of their respective obligations under the rules and procedures governing their
operations.

     Certificated Securities. Interests in the Global Securities will be
exchanged for Certificated Securities if (i) DTC notifies the Company that it is
unwilling or unable to continue as depositary for the Global Securities, or DTC
ceases to be a "Clearing Agency" registered under the Exchange Act, and a
successor depositary is not appointed by the Company within 90 days, or (ii) an
Event of Default has occurred and is continuing with respect to the Notes. Upon
the occurrence of any of the events described in the preceding sentence, the
Company will cause the appropriate Certificated Securities to be delivered.


                 CERTAIN U.S. FEDERAL INCOME TAX CONSIDERATIONS

     The following is a summary of the material United States federal income tax
consequences of the exchange of the Old Notes for New Notes and the ownership
and disposition of the Notes to U.S. Holders (as defined below). This summary is
based on the Internal Revenue Code of 1986, as amended to the date hereof (the
"Code"), administrative pronouncements, judicial decisions and existing and
proposed Treasury Regulations, changes to any of which subsequent to the date of
this Prospectus may affect the tax consequences described herein, possibly with
retroactive effect. This summary discusses only Notes held as capital assets
within the meaning of Section 1221 of the Code. It does not discuss all of the
tax consequences that may be relevant to a holder in light of his particular
circumstances or to holders subject to special rules, such as persons who are
not U.S. Holders, certain financial institutions, insurance companies, dealers
in securities and holders who hold the Notes as part of a straddle or a hedging
or conversion transaction. Persons considering the exchange of the Old Notes for
New Notes should consult their tax advisors with regard to the application of
the United States federal income tax laws to their particular situations as well
as any tax consequences arising under the laws of any state, local or foreign
taxing jurisdiction.

     As used herein, the term "U.S. Holder" means a beneficial owner of an Old
Note who exchanges it for a New Note and that for United States federal income
tax purposes is (i) a citizen or resident of the United States, (ii) a
corporation, partnership or other entity created or organized in or under the
laws of the United States or of any political subdivision thereof, (iii) an
estate the income of which is subject to United States federal income taxation
regardless of its source or (iv) a trust if a court within the United States is
able to exercise primary supervision over the administration of the trust and
one or more United States persons have the authority to control all substantial
decisions of the trust. The term also includes certain former citizens or
residents of the United States.

     Tax Consequences of the Exchange of Old Notes for New Notes

     There will be no federal income tax consequences to Holders exchanging Old
Notes for New Notes pursuant to the Exchange Offer. For federal income tax
purposes, the New Notes will be considered a continuation of the Old Notes and
the exchange of Old Notes for New Notes hereunder will not alter the federal
income tax consequences, including the accrual of original issue discount
("OID") on the Notes, as described below, of owning the Notes to Holders. A U.S.
Holder will have the same adjusted basis and holding period in the New Note as
it had in the Old Note immediately before the exchange.

     The discussion below relating to the Notes is equally applicable to the Old
Notes and the New Notes.

     Stated Interest

     Payments of stated interest on the Notes will not be separately taxable to
holders thereof, but, rather, such stated interest will be included in income as
original issue discount ("OID") on an accrual basis, as described below.

     Original Issue Discount

     The excess of a Note's "stated redemption price at maturity" over its
"issue price" will generally constitute OID for federal income tax purposes. The
stated redemption price at maturity of a Note will equal the sum of all cash
payments (whether denominated as principal or interest) payable on the Notes.
The issue price of a Note is equal the first price to the public (not including
bond houses, brokers, or similar persons or organizations acting in the capacity
of underwriters, placement agents, or wholesalers) at which a substantial amount
of the Notes is sold for money. Regardless of their method of accounting, U.S.
Holders of the Notes will be required to include such OID in income for United
States federal income tax purposes as it accrues, in accordance with a constant
yield method based on a compounding of interest, before the receipt of cash
payments attributable to such income. Under this method, U.S. Holders of the
Notes generally will be required to include in income increasingly greater
amounts of OID in successive accrual periods.

     The Company does not intend to treat the possibility of an optional
redemption or repurchase of the Notes as giving rise to any additional accrual
of OID or recognition of ordinary income upon redemption, sale or exchange of
the Notes. U.S. Holders may wish to consider that United States Treasury
Regulations regarding the treatment of certain contingencies were recently
issued and may wish to consult their tax advisers in this regard.

     Market Discount and Premium

     If a U.S. Holder purchased a Note for an amount that was less than its
"adjusted issue price," the amount of the difference would be treated as "market
discount" for United States federal income tax purposes, unless such difference
was less than a specified de minimis amount. The adjusted issue price of a Note
is defined as the sum of the issue price of the Note and the aggregate amount of
previously accrued OID, less any prior principal and interest payments on the
Note.

     Under the market discount rules of the Code, a U.S. Holder will be required
to treat any prior payment on, or any gain on the sale, exchange, retirement or
other disposition of, a Note as ordinary income to the extent of the market
discount which has not previously been included in income (pursuant to an
election by the Holder to include such market discount in income as it accrues)
and is treated as having accrued on such Note at the time of such payment or
disposition. If such Note is disposed of in a nontaxable transaction (other than
as provided in Code Sections 1276(c) and (d)), accrued market discount will be
includible as ordinary income to the U.S. Holder as if such Holder had sold the
Note at its then fair market value. In addition, unless the U.S. Holder elects
to include market discount in income as it accrues, the U.S. Holder may be
required to defer, until the maturity of the Note or its earlier disposition
(including a nontaxable transaction other than as provided in Code Sections
1276(c) and (d)), the deduction of all or a portion of the interest expense on
any indebtedness incurred or maintained to purchase or carry such Note.

     A U.S. Holder who purchased a Note for an amount that was greater than its
adjusted issue price but less than its stated redemption price at maturity would
be considered to have purchased such Note at an "acquisition premium." Under the
acquisition premium rules of the Code and the regulations thereunder, unless
such Holder makes the election described under "Election to Treat all Interest
as Original Issue Discount" below, the amount of OID which such Holder must
include in its gross income with respect to such Note for any taxable year will
be reduced by the portion of such acquisition premium properly allocable to such
year.

     Election to Treat All Interest as Original Issue Discount.

     A U.S. Holder may elect to include in gross income all interest that
accrues on a Note using the constant-yield method described above under the
heading "Original Issue Discount", with the modifications described below. For
purposes of this election, interest includes stated interest, OID, de minimis
OID, market discount, de minimis market discount and unstated interest, as
adjusted by any acquisition premium. As provided for above, payments of stated
interest on the Notes will already be included in income as OID.

     In applying the constant-yield method to a Note with respect to which this
election has been made, the issue price of the Note will equal the electing U.S.
Holder's adjusted basis in the Note immediately after its acquisition and the
issue date of the Note will be the date of its acquisition by the electing U.S.
Holder. This election will generally apply only to the Note with respect to
which it is made and may not be revoked without the consent of the Internal
Revenue Service.

     If the election to apply the constant-yield method to all interest on a
Note is made with respect to a Note with market discount, the electing U.S.
Holder will be treated as having made the election discussed above under "Market
Discount" to include market discount in income currently over the life of all
debt instruments held or thereafter acquired by such U.S. Holder.

     Sale, Exchange or Retirement of the Notes

     Upon the sale, exchange or retirement of a Note, a U.S. Holder will
recognize taxable gain or loss equal to the difference between the amount
realized on such sale, exchange or retirement and such U.S. Holder's adjusted
tax basis in the Note. A U.S. Holder's adjusted tax basis in a Note will
generally equal the cost of such Note to the Holder, increased by the amount of
any market discount and OID previously included in income by such U.S. Holder
with respect to such Note and reduced by any principal and interest payments
received by the U.S. Holder. Except as otherwise described under "Market
Discount and Premium" above, gain or loss realized on the sale, exchange or
retirement of a Note will be capital gain or loss. Recently enacted legislation
includes substantial changes to the United States federal taxation of capital
gains recognized by individuals, including a 20% maximum tax rate for certain
gains from the sale of capital assets held for more than 18 months. The
deduction of capital losses is subject to certain limitations. Prospective
investors should consult their tax advisors regarding the treatment of capital
gains and losses.

     Backup Withholding and Information Reporting

     Certain noncorporate U.S. Holders may be subject to information reporting
and backup withholding at a rate of 31% on payments of principal, premium, if
any, and interest (including OID) on, and the proceeds of a disposition of, a
Note. Backup withholding will apply only if the U.S. Holder (i) fails to furnish
its Taxpayer Identification Number ("TIN") which, in the case of an individual,
would be his or her Social Security Number, (ii) furnishes an incorrect TIN,
(iii) is notified by the IRS that it has failed to properly report payments of
interest and dividends or (iv) under certain circumstances, fails to certify,
under penalty of perjury, that it has furnished a correct TIN and has not been
notified by the IRS that it is subject to backup withholding. U.S. Holders
should consult their tax advisors regarding their qualification for an exemption
from backup withholding and the procedure for obtaining such an exemption if
applicable.

     The amount of any backup withholding from a payment to a U.S. Holder will
be allowed as a credit against such U.S. Holder's United States federal income
tax liability and may entitle such U.S. Holder to a refund, provided that the
required information is furnished to the IRS.

     The Company will furnish annually to the IRS and to record holders of the
Notes (other than with respect to certain exempt holders) information relating
to the stated interest and the OID accruing during the calender year. Such
information will be based on the amount of OID that would have accrued to a U.S.
Holder who acquired the Note on original issue.

 
                              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 such 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 where
such Old Notes were acquired as a result of market-making activities or other
trading activities. The Company has agreed that for a period of 90 days after
the Expiration Date, it will make this Prospectus, as amended or supplemented,
available to any such broker-dealer for use in connection with any such resale.
In addition, until        , 1998 (90 days after the date of this Prospectus),
all dealers effecting transactions in the New Notes may be required to deliver
a prospectus.

     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 concessions from any such
broker-dealer and/or purchasers of any such 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 or dealer that participates in a distribution of
such New Notes may be deemed to be an "underwriter" within the meaning of the
Securities Act and any profit on any such 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.

     For a period of 90 days after the Expiration Date the Company will promptly
send additional copies of this Prospectus and any amendment or supplement to
this Prospectus to any broker-dealer that requests such documents in the Letter
of Transmittal.

     The Company has agreed in the Registration Rights Agreement to indemnify
each broker-dealer reselling New Notes pursuant to this Prospectus, and their
officers, directors and controlling persons, against certain liabilities in
connection with the offer and sale of the New Notes, including liabilities under
the Securities Act, or to contribute to payments that such broker-dealers may be
required to make in respect thereof.

                        REPORT OF INDEPENDENT ACCOUNTANTS



     To the Shareholders of RCN Corporation:

     We have audited the accompanying consolidated balance sheets of RCN
Corporation and Subsidiaries as of December 31, 1997 and 1996, and the related
consolidated statements of operations, changes in shareholders' equity and cash
flows for each of the three years in the period ended December 31, 1997. 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, the consolidated financial statements referred to above
present fairly, in all material respects, the consolidated financial position of
RCN Corporation and Subsidiaries as of December 31, 1997 and 1996, and the
consolidated results of their operations and their cash flows for each of the
three years in the period ended December 31, 1997, in conformity with generally
accepted accounting principles.

                                 RCN CORPORATION
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                  (Thousands of Dollars Except Per Share Data)



1. BACKGROUND AND BASIS OF PRESENTATION

     Prior to September 30, 1997, RCN Corporation (the "Company" or "RCN") was
operated as part of C-TEC Corporation ("C-TEC"). On September 30, 1997, C-TEC
distributed 100 percent of the outstanding shares of common stock of its wholly
owned subsidiaries, RCN Corporation ("RCN") and Cable Michigan, Inc. ("Cable
Michigan") to holders of record of C-TEC's Common Stock and C-TEC's Class B
Common Stock as of the close of business on September 19, 1997 (the
"Distribution") in accordance with the terms of a Distribution Agreement dated
September 5, 1997 among C-TEC, RCN and Cable Michigan. RCN consists primarily of
C-TEC's bundled residential voice, video and Internet access operations in the
Boston to Washington, D.C. corridor, its existing New York, New Jersey and
Pennsylvania cable television operations, a portion of its long distance
operations and its international investment in Megacable, S.A. de
C.V.("Megacable") Cable Michigan, Inc. consists of C-TEC's Michigan cable
operations, including its 62% ownership in Mercom, Inc.. In connection with the
Distribution, C-TEC changed its name to Commonwealth Telephone Enterprises, Inc.
("CTE").

     The consolidated financial statements have been prepared using the
historical basis of assets and liabilities and historical results of operations
of all wholly and majority owned subsidiaries. However, the historical financial
information presented herein reflects periods during which the Company did not
operate as an independent company and accordingly, certain assumptions were made
in preparing such financial information. Such information, therefore, may not
necessarily reflect the results of operations, financial condition or cash flows
of the Company in the future or what they would have been had the Company been
an independent, public company during the reporting periods. All material
intercompany transactions and balances have been eliminated. Investments
accounted for by the equity method include a 40% interest in Megacable, a
Mexican cable television system operator. Joint ventures which the Company
controls and in which the minority investors do not possess significant veto
rights are consolidated. Other joint ventures are accounted for by the equity
method.

     C-TEC's corporate services group has historically provided substantial
support services such as finance, cash management, legal, human resources,
insurance and risk management and its financial statements are included in the
consolidated financial statements of the Company. Prior to the Distribution, the
corporate office allocated the cost for these services pro rata among the
business units supported primarily based on assets; contribution to consolidated
earnings before interest, depreciation, amortization, and income taxes; and
number of employees. In the opinion of management, the method of allocating
these costs is reasonable; however, the costs of these services remaining with
the Company after allocation to C-TEC's other business units are not necessarily
indicative of the costs that would have been incurred by the Company on a
stand-alone basis. Also included in the Company's consolidated financial
statements are the financial statements of the corporate financial services
company which invests excess cash of, and advances funds to the Company and
prior to the Distribution, C-TEC. The financial services company charges
interest expense on outstanding advances and pays interest income on excess cash
invested for affiliates.

     CTE, RCN and Cable Michigan have entered into certain agreements providing
for the Distribution, and governing various ongoing relationships, including the
provision of support services, between the three companies, including a
distribution agreement and a tax-sharing agreement.

2.  SEGMENT INFORMATION

     The Company is developing advanced fiber optic networks to provide a wide
range of telecommunications services including local and long distance
telephone, video programming and data services (including high speed Internet
access), primarily to residential customers in selected high density markets in
the Boston to Washington, D.C. corridor. The Company also seeks to serve certain
commercial accounts on or near its networks. RCN's initial advanced fiber
optic networks have been established in New York City and, through a joint
venture with the Boston Edison Company ("BECO"), in Boston and surrounding
communities. RCN has also entered into a joint venture named Starpower
Communications, LLC ("Starpower") with Pepco Communications, LLC ("Pepco
Communications"), an indirect wholly owned subsidiary of Potomac Electric Power
Company ("PEPCO"), to develop an advanced fiber network in the Washington, D.C.
area. In February 1998, RCN acquired Boston's and Washington, D.C.'s largest
Internet service providers ("ISP"), Ultranet Communications, Inc. ("Ultranet")
and Erols Internet, Inc. ("Erols"), respectively. The Company also has hybrid
fiber/coaxial operations in New York (outside New York City), New Jersey and
Pennsylvania, wireless video operations in New York City and certain other
operations, including long distance telephone.

3. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     Use of Estimates - The preparation of financial statements in conformity
with generally accepted accounting principles requires management to make
estimates and assumptions that affect the reported 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.

     Cash and Temporary Cash Investments - For purposes of reporting cash flows,
the Company considers all highly liquid investments purchased with an original
maturity of three months or less to be temporary cash investments.
Temporary cash investments are stated at cost which approximates market.

     Short Term Investments and Investments Restricted for Debt Service -
Management determines the appropriate classification of its investments in debt
and equity securities at the time of purchase and reevaluates such determination
at each balance sheet date in accordance with Statement of Financial Accounting
Standards No. 115 -- "Accounting for Certain Investments in Debt and Equity
Securities." At December 31, 1997 and 1996, marketable debt and equity
securities have been categorized as available for sale. The Company states its
short term investments at cost, which approximates market. Investments
restricted for debt service have been categorized as held to maturity.

     Property, Plant and Equipment and Depreciation - Property, plant and
equipment reflects the original cost of acquisition or construction, including
payroll and related costs such as taxes, pensions and other fringe benefits, and
certain general administrative costs.

     Depreciation is provided on the straight-line method based on the useful
lives of the various classes of depreciable property. The average estimated
lives of depreciable property, plant and equipment are:

                                                          Lives    
                                                       ----------- 
     Hybrid fiber/coaxial plant                         5-22 years 
     Advanced fiber plant                              10-15 years 
     Wireless & other plant                              5 years   
     Buildings and leasehold improvements               5-45 years 
     Furniture, fixtures and vehicles                   3-10 years 
     Other                                               3 years   

     Repairs of all property, plant and equipment and minor replacements and
renewals are charged to expense as incurred. Major replacements and betterments
are capitalized. Gain or loss is recognized on major retirements and
dispositions.

     Intangible Assets - Intangible assets are amortized on a straight-line
basis over the expected period of benefit ranging from 2 to 15 years.

     Accounting for Impairments - The Company follows the provisions of
Statement of Financial Accounting Standards No. 121 -- "Accounting for the
Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed of "
("SFAS 121"). SFAS 121 requires that long-lived assets and certain identifiable
intangibles to be held and used by an entity be reviewed for impairment whenever
events or changes in circumstances indicate that the carrying amount of an asset
may not be recoverable. In performing the review for recoverability, the Company
estimates the future cash flows expected to result from the use of the asset and
its eventual disposition. If the sum of the expected net future cash flows
(undiscounted and without interest charges) is less than the carrying amount of
the asset, an impairment loss is recognized. Measurement of an impairment loss
for long-lived assets and identifiable intangibles expected to be held and used
is based on the fair value of the asset.

     No impairment losses have been recognized by the Company pursuant to SFAS
121.

     Revenue Recognition - Local telephone service revenue is recorded as earned
based on tariffed rates. Long distance telephone service revenue is recorded
based on minutes of traffic processed and tariffed rates or contracted fees.
Revenues from cable programming services are recorded in the month the service
is provided. Internet access service revenues are recorded based on contracted
fees.

     Advertising Expense - Advertising costs are expensed as incurred.
Advertising expense charged to operations was $12,203, $1,441 and $862 in 1997,
1996 and 1995, respectively.

     Stock Based Compensation - The Company applies Accounting Principles Board
Opinion No. 25 -- "Accounting for Stock Issued to Employees" ("APB 25") in
accounting for its stock plans. The Company has adopted the disclosure - only
provisions of Statement of Financial Accounting Standards No. 123 -- "Accounting
for Stock-Based Compensation" ("SFAS 123").

     Earnings (loss) per share - The Company has adopted  statement of Financial
Accounting Standards No. 128 --"Earnings Per Share" ("SFAS 128"). Basic earnings
(loss) per share is computed  based on net income (loss) divided by the weighted
average number of shares of common stock outstanding during the period.

     Diluted earnings (loss) per share is computed based on net income (loss)
divided by the weighted average number of shares of common stock outstanding
during the period after giving effect to convertible securities considered to be
dilutive common stock equivalents. The conversion of stock options during
periods in which the Company incurs a loss from continuing operations is not
assumed since the effect is anti-dilutive. The number of stock options which
would have been converted in 1997 and have a dilutive effect if the Company had
income from continuing operations is 517,506.

     For periods prior to October 1, 1997, during which the Company was a wholly
owned subsidiary of C-TEC, earnings (loss) per share was calculated by dividing
net income (loss) by the number of average common shares of C-TEC outstanding,
based upon a distribution ratio of one share of Company common equity for each
share of C-TEC common equity owned.

</TABLE>

     Income Taxes - The Company and its subsidiaries report income for federal
tax purposes on a consolidated basis.. Prior to the Distribution, the Company
and its subsidiaries were included in the consolidated federal income tax return
of C-TEC. Income tax expense is allocated to subsidiaries on a separate return
basis except that the Company's subsidiaries receive benefit for the utilization
of net operating losses and investment tax credits included in the consolidated
return even if such losses and credits could not have been used on a separate
return basis. The Company accounts for income taxes using Statement of Financial
Accounting Standards No. 109 -- "Accounting for Income Taxes." The statement
requires the use of an asset and liability approach for financial reporting
purposes. The asset and liability approach requires the recognition of deferred
tax assets and liabilities for the expected future tax consequences of temporary
differences between financial reporting basis and tax basis of assets and
liabilities. If it is more likely than not that some portion or all of a
deferred tax asset will not be realized, a valuation allowance is recognized.

     Investment tax credits ("ITC") for the Company have been deferred in prior
years and are being amortized over the average lives of the applicable property.

     Foreign Currency Translation - The Company has a 40% interest in Megacable.
For purposes of determining its equity in the earnings of Megacable, the Company
translates the revenues and expenses of Megacable into U.S. dollars at the
average exchange rates that prevailed during the period. Assets and liabilities
are translated into U.S. dollars at the rates in effect at the end of the fiscal
period. Prior to 1997, the Company's share of the gains or losses that result
from this process are shown in the cumulative translation adjustment account in
the common shareholders' equity section of the balance sheet. Effective January
1, 1997, since the three-year cumulative rate of inflation at December 31, 1996
exceeded 100%, Mexico is treated for accounting purposes as having a highly
inflationary economy. As a result, the financial statements of Megacable are
remeasured as if the functional currency were the U.S. dollar. The remeasurement
of the Mexican peso into U.S. dollars creates translation adjustments which are
included in net income. The Company's proportionate share of gains and losses
resulting from transactions of Megacable, which are made in currencies different
from its own, are included in income as they occur.

4.  BUSINESS COMBINATIONS

     The following business combinations were transacted by wholly owned
subsidiaries of C-TEC. The acquired businesses were transferred to the Company
in connection with the Distribution.

     On August 30, 1996, FNY Holding Company, Inc., formerly a wholly owned
subsidiary of C-TEC ("FNY") acquired from Kiewit Telecom Holdings, C-TEC's
controlling shareholder at the time, an 80.1% interest in Freedom New York, LLC
and all related rights and liabilities ("Freedom") for cash consideration of
approximately $29,000. In addition, FNY assumed liabilities of approximately
$7,600. (In March 1996, Freedom had acquired the wireless cable television
business of Liberty Cable Television). The acquisition was accounted for as a
purchase, and accordingly, Freedom is included in the Company's consolidated
financial statements since September 1996. The full fair value of assets
acquired and liabilities assumed has been reflected in the Company's financial
statements with minority interest reflecting the separate 19.9% ownership.

     FNY allocated the purchase price paid on the basis of the fair value of
property, plant and equipment and identifiable intangible assets acquired and
liabilities assumed. There was no excess cost over fair value of net assets
acquired.

     Contingent consideration of $15,000 was payable in cash and was to be based
upon the number of net eligible subscribers, as defined in the Acquisition
Agreement, in excess of 16,563 delivered to the Company. The contingent
consideration is not included in the acquisition cost total above but was to
have been recorded when and if the future delivery of subscribers occurred. In
addition, FNY paid $922 to Kiewit Telecom Holdings which represents compensation
for foregone interest on the amount invested by Kiewit Telecom Holdings in
Freedom. This amount has been charged to operations.

     On March 21, 1997, the Company paid $15,000 in full satisfaction of
contingent consideration payable for the original acquisition of Freedom.
Additionally, pursuant to the terms of the Freedom Operating Agreement, the
assets of RCN Telecom Services of New York, Inc., a wholly-owned subsidiary of
RCN, were contributed to Freedom, in which the Company had an 80.1% ownership
interest prior to such contribution. Subsequent to this contribution, the
Company paid $15,000 to acquire the minority ownership of Freedom. These amounts
were primarily allocated to excess cost over fair value of net assets acquired
and are being amortized over a period of approximately six years. The Company
also paid $10,000 to terminate a marketing services agreement between Freedom
and an entity controlled by Freedom's former minority owners. The Company
charged this amount to operations for the quarter ended March 31, 1997.

     On May 15, 1995, C-TEC Cable Systems, Inc, ("RCN Cable") formerly a wholly
owned subsidiary of C-TEC, acquired 40% of the outstanding common stock of Twin
County Trans Video, Inc. ("Twin County") in exchange for cash of approximately
$26,300, including a $1,000 deposit made in 1994, and a $4,000, 5% promissory
note of RCN Cable. In addition, RCN Cable paid $11,000 in consideration of a
noncompete agreement and assumed liabilities of approximately $16,400. The
remaining shares were subject to an escrow agreement, pending completion of the
merger, and were required to be voted under the direction of RCN Cable. As of
May 15, 1995, RCN Cable also assumed management of Twin County. As a result, RCN
Cable had control of Twin County and accordingly Twin County is consolidated in
the Company's financial statements since May 1995, the date of the original
acquisition. The remaining outstanding common stock of Twin County was acquired
in September 1995 in exchange for $52,000 stated value redeemable convertible
preferred stock of C-TEC. The preferred stock has a stated dividend rate of 5%,
beginning January 1, 1996. The fair value of the preferred stock, as determined
by an independent appraiser was $39,500 which was recorded as additional paid-in
capital to the Company. In 1996, the $4,000 promissory note was canceled and RCN
Cable paid cash of $500 in settlement of certain purchase price adjustments.

     RCN Cable has allocated the purchase price paid for Twin County on the
basis of the fair value of property, plant and equipment and identifiable
intangible assets acquired and liabilities assumed. The excess of the
consideration for the acquisition over the fair value of the net assets acquired
of approximately $16,700 has been allocated to goodwill and is being amortized
over a period of approximately 10 years.

     In January 1995, RCN International Holdings, Inc. (formerly C-TEC
International, Inc.), formerly a wholly owned subsidiary of C-TEC, purchased a
40% equity position in Megacable. The aggregate consideration for the purchase
was cash of $84,115. The Company accounts for its investment by the equity
method of accounting. The original excess cost over the underlying equity in the
net assets acquired is approximately $94,000, which is being amortized on a
straight-line basis over 15 years.

     In January 1995, RCN Cable purchased the assets of Higgins Lake Cable, Inc.
for cash of approximately $4,750.

     In June 1995, C-TEC invested approximately $2,220 for a one-third interest
in a partnership which intends to provide alternative access telephone service
to commercial subscribers. C-TEC transferred this investment to RCN Cable in
1996 at net book value of $1,977. The Company disposed of its investment in 1997
and realized a gain of $661.

     In November 1995, the Company purchased the assets used in the provision of
residential telephone services in New York by RealCom Office Communications,
Inc. for cash of approximately $1,050.

venture to utilize 126 fiber miles of BECO's fiber optic network to deliver
RCN's comprehensive communications package in Greater Boston. The venture, in
the form of an unregulated entity with a term expiring in the year 2060, was
formed pursuant to a joint venture agreement dated December 23, 1996 (the
"Boston Joint Venture Agreement") providing for the organization and operation
of RCN-BECOCOM, LLC ("RCN-BECOCOM"). RCN-BECOCOM was organized to own and
operate an advanced fiber optic telecommunications network and to provide, in
the market in and around Boston, Massachusetts , voice, video and data services,
as well as the communications support component of energy related customer
services offered by BECO. RCN owns 51% of the equity interest in RCN-BECOCOM and
BECO, owns the remaining 49% interest. Future capital contributions are required
to be made on a 51% and 49% basis for RCN and BECO, respectively.

     The closing of the transactions contemplated by the Boston Joint Venture
Agreement occurred on June 17, 1997. RCN will manage the business of RCN-BECOCOM
pursuant to the terms of the Management Agreement and, in consideration
therefor, will receive reimbursement for its reasonable costs, and a
performance-based fee (based on factors including the number of subscribers and
operating cash flow) to be determined by agreement of RCN and RCN-BECOCOM. The
initial term of the agreement expires on December 31, 2001. The agreement
provides for automatic successive three-year renewal periods, unless notice is
given ninety days before the end of the period. As a result of its ownership,
management and control, this joint venture with BECO is consolidated in RCN's
financial statements.

     Pursuant to an Indefeasible Right of Use Agreement ("IRU Agreement") , BECO
will, for certain agreed upon fees, (i) provide construction services to build
out the Network, (ii) make available to RCN-BECOCOM (a) all of the available
capacity of BECO's existing fiber backbone, and (b) the ability to use BECO's
real estate, poles, easements and other interests for the construction and
operation of the Network and (iii) maintain the Network. BECO's construction
obligations expire on June 17, 2007 and the term of the IRU Agreement expires on
December 31, 2060. One year before each respective expiration date, BECO agrees
to commence good-faith negotiations to extend construction obligations beyond
June 17, 2007 and to allow continued use of BECO's facilities beyond December
31, 2060. The fair value of the IRU transferred by BECO to the joint venture is
reflected as "Advanced Fiber Plant" in property, plant and equipment.

     BECO will have the right at the time of the Distribution and every two
years thereafter to convert its ownership interest in RCN-BECOCOM into the
Common Stock of RCN pursuant to specific terms and conditions. If BECO exercises
its conversion rights, BECO will remain obligated to make 49% of all cash
contributions by the parties and any cash contributions made after conversion
will result in it owning a portion of RCN-BECOCOM based on the value of
RCN-BECOCOM at the time of the contribution. BECO may exercise its conversion
rights in whole or in part from time to time. In January 1998, BECO notified RCN
that it has elected to exercise its option to the full extent permitted by the
Exchange Agreement with respect to 1997. RCN and BECO are presently in
discussions with respect to the calculation of the agreed upon value for the
exercise of such option.

     b. On August 1, 1997, RCN and Potomac Capital Investment Corporation
("PCI"), a wholly owned subsidiary of PEPCO, entered into a letter of intent
(the "Letter of Intent") to form a joint venture which will own and operate a
communications network to provide voice, video, data and other communications
services to residential and commercial customers in the greater Washington,
D.C., Virginia and Maryland area (the "Washington, D.C. Market"). Starpower, an
unregulated limited liability company with a perpetual term, was formed on
October 28, 1997 to construct, own, lease, operate and market a network for the
selling of voice, video, data and other telecommunications services to all
potential commercial and residential customers in the Washington, D.C. Market.
RCN, owns 50% of the equity interest in Starpower and PCI, owns the remaining
50% interest.

     The closing of the Starpower joint venture (the "Starpower Closing")
occurred on December 19, 1997.

     Pursuant to the Amended and Restated Operating Agreement, RCN and Pepco
Communications are each required to make additional capital contributions in
accordance with a schedule set forth in such agreement on a 50%/50% basis.
Failure of either RCN or Pepco Communications to make a scheduled capital
contribution or to vote in favor of certain additional capital contributions may
result in the recalculation of equity interests. The business and affairs of
Starpower is to be managed by RCN and Pepco Communications. So long as RCN and
Pepco Communications maintain a 50%/50% equity interest in the joint venture,
each of RCN and Pepco Communications will appoint three members to the operating
committee, the approval of which is required for any business action. Certain
fundamental business actions, such as mergers, acquisitions, sales of
substantially all of the assets, liquidation and amendments to the certificate
of organization or any agreement signed at the Starpower Closing, require the
unanimous approval of the operating committee regardless of whether the parties
continue to maintain a 50%/50% ownership interest. As a result of the joint
control, Starpower is accounted for under the equity method of accounting.

     A subsidiary of RCN will provide support services including customer
service, billing, marketing and certain administrative, accounting and technical
support services, each of which shall be provided at cost.

     c. The basis of the Company's investment in Megacable exceeded its
underlying equity in the net assets of Megacable when acquired by approximately
$94,000 which excess is being amortized on a straight-line basis over 15 years.
At December 31, 1997, the unamortized excess over the underlying equity in the
net assets was $75,886. The Company recorded its proportionate share of (losses)
and amortization of excess cost over net assets of ($3,869), ($2,190) and
($3,061) in 1997, 1996 and 1995, respectively.

     Effective January 1, 1997, since the three-year cumulative rate of
inflation at December 31, 1996 exceeded 100%, Mexico is being treated for
accounting purposes under Statement of Financial Accounting Standards No. 52
- --"Foreign Currency Translation", as having a highly inflationary economy. As a
result, the financial statements of Megacable are remeasured as if the
functional currency were the U.S. dollar. The remeasurement of the Mexican peso
into U.S. dollars creates translation adjustments which are included in net
income. Exchange gains (losses) of $(12), $247, and $(932) in 1997, 1996, and
1995, respectively, including translation losses in 1997, are included in the
respective statements of operations through the Company's proportionate share of
losses of Megacable.

     The following table reflects the summarized financial position and results
of operations of Megacable as of and for the years ended December 31, 1997 and
1996:

     In October 1997, pursuant to Rule 144A of the Securities Exchange Act of
1933, the Company completed an offering of 10% Senior Notes with an aggregate
principal amount of $225,000 and 11 1/8% Senior Discount Notes with an aggregate
principal amount at maturity of $601,045, both due 2007, to qualified
institutional buyers as defined in Rule 144A. The Senior Discount Notes were
issued at a discount and generated gross proceeds to the Company of $350,000. In
December 1997, the Company commenced an SEC registered Exchange Offer of its 10%
Senior Notes due 2007, Series B for any and all outstanding 10% Senior Notes due
2007, Series A and its 11 1/8% Senior Discount Notes due 2007, Series B for any
and all outstanding 11 1/8% Senior Discount Notes due 2007 Series A. The
Exchange Offer closed in January of 1998. All outstanding notes were exchanged.

     The 10% Senior Notes were issued under an indenture dated October 17, 1997
(the "10% Indenture") between the Company and The Chase Manhattan Bank, as
Trustee. The 10% Senior Notes are general senior obligations of the Company
which mature on October 15, 2007 and are collateralized by a pledge of the
Escrow Account which contains approximately $61,000 of the net proceeds from the
sale of the 10% Senior Notes plus approximately $1,000 of aggregate interest,
representing funds that, together with the future proceeds from the investment
thereof, will be sufficient to pay interest on the 10% Senior Notes for six
scheduled interest payments. Interest on the 10% Senior Notes is payable in cash
semi-annually in arrears on each April 15 and October 15, commencing April 15,
1998.

     The 10% Indenture contains certain covenants that, among other things,
limit the ability of the Company and its subsidiaries to incur indebtedness, pay
dividends, prepay subordinated indebtedness, repurchase capital stock, engage in
transactions with stockholders and affiliates, create liens, sell assets and
engage in mergers and consolidations.

     The 10% Senior Notes are redeemable, in whole or in part, at any time on or
after October 15, 2002 at the option of the Company. The 10% Senior Notes have
redemption prices starting at 105% of the principal amount and declining to 100%
of the principal amount, plus any accrued interest.

     The 11-1/8% Senior Discount Notes were issued under an indenture dated
October 17, 1997 (the "11-1/8% Indenture")between the Company and The Chase
Manhattan Bank, as Trustee. The 11-1/8% Senior Discount Notes are general senior
obligations of the Company, limited to $601,045 aggregate principal amount at
maturity and will mature on October 15, 2007. The 11-1/8% Senior Discount Notes
were issued at a discount to yield gross proceeds of $350,000. The 11-1/8%
Senior Discount Notes will not bear cash interest prior to October 15, 2002.

     The 11-1/8% Indenture contains certain covenants that, among other things,
limit the ability of the Company and its subsidiaries to incur indebtedness, pay
dividends, prepay subordinated indebtedness, repurchase capital stock, engage in
transactions with stockholders and affiliates, create liens, sell assets and
engage in mergers and consolidations.

     The 11-1/8% Senior Discount Notes are redeemable, in whole or in part, at
any time on or after October 15, 2002 at the option of the Company. The 11-1/8%
Senior Discount Notes have redemption prices starting at 105.562% of the
principal amount at maturity and declining to 100% of the principal amount at
maturity, plus any accrued interest.

     Certain subsidiaries of the Company, including RCN Cable, have in place a
$125,000 credit agreement comprised of two credit facilities. The first is a
five year revolving credit facility in the amount of $25,000 which provides
credit availability through June 30, 2002. Revolving loans may be repaid and
reborrowed from time to time. The second is a term credit facility in the amount
of $100,000 which is to be repaid over six years in quarterly installments from
September 30, 1999 through June 30, 2005. Interest only is due through June 30,
1999. The interest rate is based on either a LIBOR or Base Rate option, at the
election of the Company (6.82% at December 31, 1997). The credit agreement is
collateralized by a pledge by the Company of its stock in RCN Cable and may, in
the future, be secured by pledges of stock of subsidiaries of the Company. At
December 31, 1997, the entire $100,000 term credit facility is outstanding and
$3,000 of the revolving credit facility is outstanding. RCN Cable used a portion
of its initial Borrowings under the credit facilities to prepay higher priced
Senior Secured Notes. The early extinguishment of the Senior Secured Notes
resulted in an extraordinary charge of $3,210, net of taxes of $1,728. The
credit agreement contains restrictive covenants which, among other things,
require the Company to maintain certain debt to cash flow and interest coverage
ratios and place certain limitations on additional debt and investments. The
Company does not believe that these covenants will materially restrict its
activities.

     In 1989, in order to complete the August 29, 1989 Michigan Cable Television
acquisition, RCN Cable entered into a private placement of Senior Secured Notes
for $150,000 and a $70,000 Revolving Secured Credit Agreement, which was
voluntarily reduced to $60,000 in 1990 and which, in accordance with its terms,
reduced on a quarterly basis, through original scheduled maturity in September
1996. In August 1996, RCN Cable obtained an amendment and waiver related to this
Revolving Secured Credit Agreement which extended final maturity to December
1996 and increased the amount of available Borrowings. Additionally, the
restrictive covenant relating to limitations on the amount of capital
expenditures was waived for the year ending December 31, 1996. The Senior
Secured Notes were collateralized by the stock of certain cable subsidiaries of
the Company. On September 1, 1996 and on each September 1 thereafter, a
mandatory principal repayment was required on the Senior Secured Notes. The
Senior Secured Notes contained restrictive covenants which, among other things,
required maintenance of a specified debt to cash flow ratio. These notes were
prepaid in 1997 as discussed above. The Senior Secured Notes were classified as
long-term at December 31, 1996 since the Company had the intent and the ability
to refinance this obligation on a long-term basis through the above credit
facilities.

     In connection with the acquisition of Twin County Trans Video, Inc., RCN
Cable issued a $4,000 promissory note at 5% due in May 2003. The note was
unsecured. In September 1996, the note was canceled in settlement of certain
purchase price adjustments.

     Contractual maturities of long-term debt are as follows:

               Year Ending December 31,           Aggregate Amounts
               ------------------------           -----------------
          1998...................................    $   --   
          1999...................................    $ 3,750

          2001...................................    $16,250  
          2002...................................    $20,500  
          
     b.  Short-term debt

     At December 31, 1997, the Company had unused lines of credit for $5,500 at
prime (8.50% at December 31, 1997). Short-term unsecured Borrowings may be made
under these lines of credit. The amounts available under these lines of credit
are reduced by outstanding letters of credit ($3,060 at December 31,1997). All
unused lines of credit are cancelable at the option of the banks. There are no
commitment or facility fees associated with maintaining availability of the
above-mentioned lines of credit.

from affiliates of $3,186 and $501, respectively. At December 31, 1996, the
Company had tax related balances due to affiliates of $817.

     Temporary differences that give rise to a significant portion of deferred
tax assets and liabilities at December 31, are as follows:

     In the opinion of management, based on the future turnaround of existing
temporary differences for the consolidated taxpaying group, primarily
depreciation, the Company will more likely than not be able to realize
substantially all of its deferred tax assets.

     A valuation allowance has been provided for the portion of deferred tax
assets which, in the opinion of management is uncertain as to their realization.
The valuation allowance relates primarily to state net operating loss
carryforwards generated by certain subsidiaries.

     The net change in the valuation allowance for deferred tax assets during
1997 was an increase of $4,713.

     Net operating losses will expire as follows:

     The provision (benefit) for income taxes is different from the amounts
computed by applying the U.S. statutory federal tax rate of 35%. The differences

     In 1995, C-TEC received official notification of final settlement from the
Internal Revenue Service relating to the examination of C-TEC's consolidated
federal income tax returns for 1989, 1990 and 1991. The most significant
adjustment relates to the disallowance of the claimed amortization of certain
intangible assets. As a result of the disallowance, the Company's taxes payable
for prior years increased approximately $580. The amount accrued in previous
years was sufficient to satisfy the above adjustment. No additional accrual
during 1995 was required.

     In 1997 and 1996, estimated non-deductible expenses relate primarily to
charges in connection with the restructuring of the Company.

12. STOCKHOLDERS' EQUITY AND STOCK PLANS

     The Company has authorized 100,000,000 shares of $1 par value common stock
and 200,000,000 shares of $1 par value Class B nonvoting common stock. The
Company also has authorized 25,000,000 shares of $1 par value preferred stock.
At December 31, 1997, 54,989,870 shares of common stock are issued and
outstanding.

     In March 1998, the Company's Board of Directors approved a two-for-one
stock split, payable in the form of a 100% stock dividend. The record date for
the stock split is March 20, 1998. Stockholders of record at the market close on
that date will receive an additional share of RCN common stock for each share
held. The distribution date for the stock dividend will be April 3, 1998. All
share and per share data, stock option data, and market prices of the Company's
common stock have been restated to reflect this stock split.

     In connection with the Distribution, the Company Board adopted the 1997 RCN
Corporation Stock Option Plan ("the 1997 Plan"), designed to provide equity
based compensation opportunities to key employees when shareholders of the
Company have received a corresponding benefit through appreciation in the value
of RCN Common Stock.

     The 1997 Plan contemplates the issuance of incentive stock options, as well
as stock options that are not designated as incentive stock options,
performance-based stock options, stock appreciation rights, performance share
units, restricted stock, phantom stock units and other stock-based awards
(collectively, "Awards"). Up to 5,000,000 shares of Common Stock, plus 3,040,100
shares of Common Stock issuable in connection with the Distribution related
option adjustments, may be issued pursuant to Awards granted under the 1997
Plan.

     Unless earlier terminated by the Company Board, the 1997 Plan will expire
on the tenth anniversary of the Distribution. The Company Board or the
Compensation Committee may, at any time, or from time to time, amend or suspend
and, if suspended, reinstate, the 1997 Plan in whole or in part.

     Prior to the Distribution, certain employees of RCN were granted stock
option awards under C-TEC's stock option plans. In connection with the
Distribution 3,040,100 options covering Common Stock were issued. Each C-TEC
option was adjusted so that each holder would currently hold options to purchase
shares of CTE Common Stock, RCN Common Stock and Cable Michigan Common Stock.
The number of shares subject to, and the exercise price of, such options were
adjusted to take into account the Distribution and to ensure that the aggregate
intrinsic value of the resulting RCN, Cable Michigan and CTE options immediately
after the Distribution was equal to the aggregate intrinsic value of the C-TEC
options immediately prior to the Distribution.

     Information relating to stock options is as follows:

     No compensation expense related to stock option grants was recorded in 1997
as the option exercise prices were equal to fair market value on the date
granted.

     Pro forma information regarding net income and earnings per share is
required by SFAS 123, and has been determined as if the Company had accounted
for its stock options under the fair value method of SFAS 123. The fair value
for these options was estimated at the date of grant using a Black Scholes
option pricing model with weighted average assumptions for dividend yield of 0%
for 1997, 1996 and 1995; expected volatility of 38.6% prior to the Distribution
and 49.8% subsequent to the Distribution for 1997, 39.5% for 1996, and 35.9% for
1995; risk-free interest rate of 6.52%, 5.95% and 6.32% for 1997, 1996 and 1995,
respectively; and expected lives of 5 years for 1997, 1996 and 1995.

     The weighted-average fair value of options granted during 1997 was $7.46.

     For purposes of pro forma disclosures, the estimated fair value of the
options is amortized to expense over the options' vesting period. The Company's
pro forma net earnings and earnings per share were as follows:

     In November 1996, the C-TEC shareholders approved a stock purchase plan for
certain key executives (the C-TEC "Executive Stock Purchase Plan" or "C-TEC
ESPP"). Under the C-TEC ESPP, participants may purchase shares of C-TEC Common
Stock in an amount of between 1% and 20% of their annual base compensation and
between 1% and 100% of their annual bonus compensation provided, however, that
in no event shall the participant's total contribution exceed 20% of the sum of
their annual compensation, as defined by the C-TEC ESPP. Participant's accounts
are credited with the number of share units derived by dividing the amount of
the participant's contribution by the average price of a share of C-TEC Common
Stock at approximately the time such contribution is made. The share units
credited to a participant's account do not give such participant any rights as a
shareholder with respect to, or any rights as a holder or record owner of, any
shares of C-TEC Common Stock. Amounts representing share units that have been
credited to a participant's account will be distributed, either in a lump sum or
in installments, as elected by the participant, following the earlier of the
participant's termination of employment or three calendar years following the
date on which the share units were initially credited to the participant's
account. It is anticipated that, at the time of distribution, a participant will
receive one share of C-TEC Common Stock for each share unit being distributed.

     Following the crediting of each share unit to a participant's account, a
matching share of Common Stock is issued in the participant's name. Each
matching share is subject to forfeiture as provided in the C-TEC ESPP. The
issuance of matching shares will be subject to the participant's execution of an
escrow agreement. A participant will be deemed to be the holder of, and may
exercise all the rights of a record owner of, the matching shares issued to such
participant while such matching shares are held in escrow.

     Shares of restricted C-TEC Common Stock awarded under the C-TEC Executive
Stock Purchase Plan and share units awarded under the C-TEC ESPP that relate to
C-TEC Common Stock were adjusted so that following the Distribution, each such
participant was credited with an aggregate equivalent value of restricted shares
of common stock of Commonwealth Telephone Enterprises, the Company and Cable
Michigan. In 1997, the Company's Board of Directors approved the RCN Corporation
Executive Stock Purchase Plan (the "RCN ESPP"), with terms substantially the
same as the C-TEC ESPP. The number of shares which may be distributed under the
RCN ESPP as matching shares or in payment of share units is 250,000. At December
31, 1997, 61,412 matching shares have been issued under the RCN ESPP, none of
which are vested. The Company recognizes the cost of the matching shares over
the vesting period. Expense recognized in 1997 and 1996 was $80 and $145,
respectively.

13.  PENSIONS AND EMPLOYEE BENEFITS

     Prior to the Distribution, the Company's financial statements reflect the
costs experienced for its employees and retirees while included in the C-TEC
plans.

     Through December 31, 1996, substantially all employees of the Company were
included in a trusteed noncontributory defined benefit pension plan, maintained
by C-TEC. Upon retirement, employees are provided a monthly pension based on
length of service and compensation. C-TEC funds pension costs to the extent
necessary to meet the minimum funding requirements of ERISA. Substantially, all
employees of C-TEC's Pennsylvania cable television operations (formerly Twin
County Trans Video, Inc.) were covered by an underfunded plan which was merged
into C-TEC's overfunded plan on February 28, 1996.

     The information that follows relates to the entire C-TEC noncontributory
defined benefit plan. The components of C-TEC's pension cost are as follows:


                                                             1996        1995

Benefits earned during the year (service cost)............  $2,365      $1,656
Interest cost on projected benefit obligation.............   3,412       3,083
Actual return on plan assets..............................  (3,880)    (12,897)
Other components - net....................................  (1,456)      8,482
                                                           -------    --------
Net periodic pension cost.................................    $441       $ 324
                                                           =======    ========

     The following assumptions were used in the determination of the
consolidated projected benefit obligation and net periodic pension cost:

                                                                December 31,
                                                           -------------------
                                                             1996        1995
                                                           -------    --------
Discount rate.............................................    7.5%        7.0%
Expected long-term rate of return on plan assets..........    8.0%        8.0%
Weighted average long-term rate of compensation 
  increases...............................................    6.0%        6.0%

     The Company's allocable share of the consolidated net periodic pension
costs, based on the Company's proportionate share of consolidated annualized
salaries as of the valuation date, was approximately $158 and $251 for 1996 and
1995, respectively. These amounts are reflected in operating expenses. As
discussed below, no pension cost (credit) was recognized in 1997.

     In connection with the restructuring, C-TEC completed a comprehensive study
of its employee benefit plans in 1996. As a result of this study, effective
December 31, 1996, in general, employees of the Company no longer accrue
benefits under the defined benefit pension plans and became fully vested in
their benefit accrued through that date. C-TEC notified affected participants in
December 1996. In December 1996, C-TEC allocated pension plan assets of $6,984
and the related liabilities to a separate plan for employees who no longer
accrue benefits after lump sum distributions. The allocation of assets and
liabilities resulted in a curtailment/settlement gain of $4,292. The Company's
allocable share of this gain was $3,437. This gain results primarily from the
reduction of the related projected benefit obligation. The curtailed plan has
assets in excess of the projected benefit obligation. Such excess amounts to
$3,917 which, along with unrecognized items of $1,148 results in prepaid pension
cost of $2,769, which is included in "Prepayments and other" in the accompanying
1997 and 1996 consolidated balance sheets.

     The following table sets forth the plans' funded status and amounts
recognized in C-TEC's balance sheet at December 31, 1996:


Plan assets at fair value..........................................   $55,325
Actuarial present value of benefit obligations:
Accumulated benefit obligations:
Vested.............................................................    32,372
Nonvested..........................................................     1,704
                                                                   ----------

                                                                   ----------
Prepaid pension cost...............................................   $ 2,967 
                                                                   ========== 


     C-TEC's pension plan has assets in excess of the accumulated benefit
obligation. Plan assets include cash, equity, fixed income securities and pooled
funds under management by an insurance company. Plan assets include common stock
of C-TEC with a fair value of approximately $5,835 at December 31, 1996.

     Prepaid pension cost is included in "Deferred Charges and Other Assets" in
the accompanying 1996 consolidated balance sheet. The prepaid pension asset was
transferred to CTE in connection with the Distribution in 1997.

     C-TEC sponsors a 401(k) savings plan covering substantially all employees
of the Company who are not covered by collective bargaining agreements.
Contributions made by the Company to the 401(k) plan are based on a specific
percentage of employees contributions. Contributions charged to expense were
$354 and $268 in 1996 and 1995, respectively. Contributions charged to expense
in 1997 prior to the Distribution were $515.

     In connection with the Distribution, RCN established a qualified savings
plan under Section 401(k) of the Code that will also qualify as an ESOP under
Sections 401(a) and 4975(e)(7) of the Code (the "ESOP"). Eligible active
employees under the ESOP, employees of the Company Businesses who make Section
401(k) contributions and certain other employees will be allocated shares of
Company Common Stock. Contributions charged to expense in 1997 were $306.

     The Company provides certain postemployment benefits to former or inactive
employees of the Company who are not retirees. These benefits are primarily
short-term disability salary continuance. The Company accrues the cost of
postemployment benefits over employees' service lives. The Company uses the
services of an enrolled actuary to calculate the expense. Prior to the
Distribution, C-TEC allocated the cost of these benefits to the Company based on
the Company's proportionate share of consolidated annualized salaries. The
Company reimbursed C-TEC for its allocable share of the consolidated
postemployment benefit cost. The net periodic postemployment benefit cost
(credit) was approximately $458, $539 and ($106) in 1997, 1996 and 1995,
respectively.

14.  COMMITMENTS AND CONTINGENCIES

     a. The Company had various purchase commitments at December 31, 1997
related to its 1998 construction budget.

     b. Total rental expense, primarily for office space and pole rentals, was
$3,505, $3,632 and $2,846 for 1997, 1996 and 1995, respectively. At December 31,
1997, rental commitments under noncancelable leases, excluding annual pole
rental commitments of approximately $794 that are expected to continue
indefinitely, are as follows:

                                                      Aggregate
          Year                                         Amounts   
          ----                                        ---------
          1998........................................  $3,725
          1999........................................  $3,314
          2000........................................  $2,939
          2001........................................  $2,826
          2002........................................  $2,848
          Thereafter..................................  $8,501
                                                              
     c. The Company has outstanding letters of credit aggregating $3,060 at
December 31, 1997.

     d. The Company has entered into various noncancelable contracts for network
services. Future obligations under these agreements are as follows:

                                                       Network
          Year                                         Services  
          ----                                        ---------
          1998........................................  $3,026
          1999........................................  $3,064
          2000........................................  $3,012
          2001........................................  $2,762
          2002........................................    $ 12
          Thereafter..................................    $ 14
                                                                      
     e. The Company is subject to the provisions of the Cable Television
Consumer Protection and Competition Act of 1992, as amended, and the
Telecommunications Act of 1996. The Company has either settled challenges or
accrued for anticipated exposures related to rate regulation. However, there is
no assurance that there will not be additional challenges to its rates.

     f. In the normal course of business, there are various legal proceedings
outstanding. In the opinion of management, these proceedings will not have a
material adverse effect on the financial position or results of operations or
liquidity of the Company.

     g. The Company has agreed to indemnify Cable Michigan and CTE and their
respective subsidiaries against any and all liabilities which arise primarily
from or relate primarily to the management or conduct of the business of the
Company prior to the effective time of the Distribution. The Company has also
agreed to indemnify Cable Michigan and CTE and their respective subsidiaries
against 30% of any liability which arises from or relates to the management or
conduct prior to the effective time of the Distribution of the businesses of
C-TEC and its subsidiaries and which is not a true CTE liability, a true Cable
Michigan liability or a true Company liability.

     The Tax Sharing Agreement, by and among the Company, Cable Michigan and CTE
(the "Tax Sharing Agreement"), governs contingent tax liabilities and benefits,
tax contests and other tax matters with respect to tax returns filed with
respect to tax periods, in the case of the Company, ending or deemed to end on
or before the Distribution Date. Under the Tax Sharing Agreement, Adjustments
(as defined in the Tax Sharing Agreement) to taxes that are clearly attributable
to the Company Group, the Cable Michigan Group, or the CTE Group will be borne
solely by such group. Adjustments to all other tax liabilities will be borne 50%
by CTE, 30% by the Company and 20% by Cable Michigan.

     Notwithstanding the above, if as a result of the acquisition of all or a
portion of the Capital stock or assets of the Company, the Distribution fails to
qualify as a tax-free distribution under Section 355 of the Code, then the
Company will be liable for any and all increases in tax attributable thereto.

     h. Under the Starpower Amended and Restated Operating Agreement, the
Company is committed to make quarterly capital contributions aggregating the
following in the years ended December 31:

          1998........................................  $56,250 
          1999........................................  $68,750 
          2000........................................  $25,000 
          

     i. If, within five years after the Distribution, the ESOP portion of the
401(k) Plan does not hold shares representing at least 3% of the number of
shares of Company Common Stock outstanding immediately after the Distribution as
increased by the number of shares issuable to BECO pursuant to the Exchange
Agreement (collectively, "Outstanding Company Common Stock") with a market value
at such time of not less than $24,000, RCN will issue to the ESOP, in exchange
for a note from the ESOP (the "ESOP Note"), the amount of Company Common Stock
necessary to increase the ESOP's holdings of Company Common Stock to that level,
provided, however, that RCN is not obligated to issue shares to the ESOP in
excess of 5% of the number of shares of Outstanding Company Common Stock.

15. AFFILIATE AND RELATED PARTY TRANSACTIONS

     The Company had the following transactions with affiliates during the years
ended December 31, 1997, 1996 and 1995:

</TABLE>

     At December 31, 1997 and 1996, the Company has accounts receivable from
related parties of $9,829 and $12,614, respectively, for these transactions. At
December 31, 1997 and 1996, the Company has accounts payable to related parties
of $3,748 and $4,880, respectively, for these transactions.

     The Company had notes receivable of $7,914 in 1996 from advances by the
Company's corporate financial services company to CTE. The Company also had
notes receivable of $147,567 at December 31, 1996, from Cable Michigan, Inc.
primarily related to the acquisition of the Michigan cable operations and
subsequent operations. All intercompany notes receivable were settled in
connection with the Distribution.

     The Company had notes payable of $11,854 in 1996 from excess cash advanced
by CTE to the Company's corporate financial services company for investment. All
intercompany notes payable were settled in connection with the Distribution.

16.  OFF BALANCE SHEET RISK AND CONCENTRATION OF CREDIT RISK

     Certain financial instruments potentially subject the Company to
concentrations of credit risk. These financial instruments consist primarily of
trade receivables, cash and temporary cash investments, and short-term
investments.

     The Company places its cash and temporary investments with high credit
quality financial institutions and limits the amount of credit exposure to any
one financial institution. The Company also periodically evaluates the
creditworthiness of the institutions with which it invests. The Company does,
however, maintain unsecured cash and temporary cash investment balances in
excess of federally insured limits.

     The Company's trade receivables reflect a customer base primarily centered
in the Boston to Washington, D.C. corridor of the United States. The Company
routinely assesses the financial strength of its customers. As a consequence,
concentrations of credit risk are limited.

17.  DISCLOSURE ABOUT FAIR VALUE OF FINANCIAL INSTRUMENTS

     a.  Cash and temporary cash investments

     The carrying amount approximates fair value because of the short maturity
of these instruments.

     b.  Short-term investments

     Short-term investments consist of commercial paper, corporate debt
securities, certificates of deposit and federal agency notes. Short-term
investments are carried at amortized cost which approximates fair value due to
the short period of time to maturity.

     c.  Long-term investments

     Long-term investments consist of investments accounted for under the equity
method for which disclosure of fair value is not required. The note and interest
receivable are carried at cost plus accrued interest which management believes
approximates fair value.

     d.  Investments restricted for debt service

     Investments restricted for debt service consists of an amount placed in
escrow from the proceeds of the 10% Senior Notes which, together with the
proceeds from the investment thereof, will be sufficient to pay interest on the
10% Senior Notes for six scheduled interest payments. Investments restricted for
debt service are carried at amortized cost.

     e.  Long-term debt

     The fair value of fixed rate long-term debt was estimated based on the
Company's current incremental borrowing rate for debt of the same remaining
maturities. The fair value of floating rate debt is considered to be equal to
the carrying value since the debt reprices at least every six months and the
Company believes that its credit risk has not changed from the time the floating
rate debt was borrowed and therefore, it would obtain similar rates in the
current market.

     f.  Letter of credit

     The contract amount of letters of credit represents a reasonable estimate
of their value since such instruments reflect fair value as a condition of their
underlying purpose and are subject to fees competitively determined in the
marketplace.

     The estimated carrying fair value of the Company's financial instruments
are as follows at December 31:

19.  SUBSEQUENT EVENTS

     a. In February 1998, the Company completed an offering of 9.8% Senior
Discount Notes with an aggregate principal amount at maturity of $567,000, due
February 2008. The 9.8% Senior Discount Notes were issued at a discount and
generated gross proceeds to the Company of $350,587.

     The 9.8% Senior Discount Notes are general senior obligations of the
Company, limited to $567,000 aggregate principal amount at maturity and will
mature on February 15, 2008. The 9.8% Senior Discount Notes were issued at
a discount to yield gross proceeds of $350,587. The 9.8% Senior Discount Notes
will not pay cash interest prior to February 15, 2003. The yield to maturity of
the 9.8% Senior Discount Notes, determined on a semi-annual bond equivalent
basis, will be 9.8% per annum.

     The 9.8% Indenture contains certain covenants that, among other things,
limit the ability of the Company and its subsidiaries to incur indebtedness, pay
dividends, prepay subordinate indebtedness, repurchase capital stock, engage in
transactions with stockholders and affiliates, create liens, sell assets and
engage in mergers and consolidations.

     The 9.8% Senior Discount Notes are redeemable, in whole or in part, at any
time on or after February 15, 2003 at the option of the Company. The 9.8% Senior
Discount Notes may be redeemed at redemption prices starting at 104.9% of the
principal amount at maturity and declining to 100% of the principal amount at
maturity, plus any accrued and unpaid interest.

     b. On January 21, 1998, RCN entered into the Agreement and Plan of Merger
(the "Erols Merger Agreement") among RCN, Erols Internet, Inc. ("Erols"), Erol
Onaran, Gold & Appel Transfer, S.A., a British Virgin Islands corporation ("Gold
& Appel"), and ENET Holdings, Inc., a Delaware corporation and a wholly owned
subsidiary of RCN ("ENET"), to acquire all of the outstanding shares of common
stock of Erols. The merger was consummated on February 20, 1998. Erols merged
with and into ENET (the "Erols Merger"), with ENET as the surviving corporation.
The approximate total Erols Merger consideration was $29,200 in cash, 1,730,648
shares of RCN common stock plus the assumption and repayment of $5,800 of debt.
Additionally, the Company is converting approximately 999,000 Erols stock
options to 699,104 RCN stock options at an average exercise price of $3.424 per
share. The transaction was accounted for under the purchase method of
accounting.

     RCN expects to contribute to Starpower approximately 60% of the subscribers
acquired in the acquisition of Erols.

     c. On January 21, 1998, RCN, UNET Holdings, Inc., a wholly owned subsidiary
of RCN, and Ultranet Communications, Inc. ("Ultranet") entered into an Agreement
and Plan of Merger (the "Ultranet Merger Agreement"). The total consideration
for the acquisition was 7,368 in cash, 890,384 shares of RCN common stock, and
$3,000 in deferred compensation. Additionally, the Company is converting 63,500
UltraNet stock options to 117,052 RCN stock options at an average exercise price
of $1.825 per share and making cash payments aggregating approximately $503 to
certain other holders of UltraNet stock options. The transaction was consummated
on February 27, 1998. The transaction was accounted for under the purchase
method of accounting.

     RCN expects to contribute to RCN-BECOCOM approximately 30% of the
subscribers acquired in the acquisition of Ultranet.

     d. RCN paid $12,500 in cash in January 1998 as its initial capital
contribution to Starpower.

     e. In January 1998, BECO notified RCN that it has elected to exercise its
option to the full extent permitted by the Exchange Agreement (Note 7) with
respect to 1997. RCN and BECO are presently in discussions with respect to the
calculation of the agreed upon value for the exercise of such option.

     f. On February 27, 1998, the Company entered into an Agreement and Plan of
Merger (the "Merger Agreement") with Lancit Media Entertainment, Ltd. ("Lancit")
and LME Acquisition Corporation ("MergerSub"), a wholly owned subsidiary of RCN.
Pursuant to the terms of the Merger Agreement, MergerSub will be merged with and
into Lancit (the "Merger") such that immediately following the Merger, Lancit
will be a wholly-owned subsidiary of RCN. The consummation of the Merger is
subject to customary conditions, including the adoption and approval of the
Merger and the Merger Agreement by the stockholders of Lancit in accordance with
the provisions of applicable law and the filing and effectiveness of a
registration statement of RCN. There is no assurance that this transaction will
be consummated.

                              EROLS INTERNET, INC.

                    NOTES TO FINANCIAL STATEMENTS (continued)

1.       Organization

     Erols Internet, Inc. (the "Company") began operations on August 1, 1995 as
a division of OEO, Inc., which changed its name to Erols Internet, Inc. on
December 2, 1996. The Company is an Internet service provider ("ISP"), offering
a combination of low priced, high quality Internet access in targeted markets
located throughout the corridor stretching from Massachusetts to Virginia.

     From its inception on August 1, 1995 through December 2, 1996, the Company
operated as a division of OEO, Inc., a company that had two divisions consisting
of the Company's ISP operations and a computer, television and video cassette
recorder repair division. On December 2, 1996, OEO, Inc. reincorporated in the
State of Delaware and changed its name to Erols Internet, Inc. Shortly
thereafter, on December 28, 1996, the assets and liabilities of the computer,
television and video cassette recorder repair division were spun-off to a newly
formed Virginia corporation named Erol's Computer & TV/VCR, Inc.

     The financial statements of Erols Internet, Inc. as of and for the five
month period ended December 31, 1995 have been prepared on the basis that Erols
Internet, Inc. operated as a division of OEO, Inc. and accordingly, there are no
equity accounts such as common stock or paid in capital related to the Internet
division. The financial statements of Erols Internet, Inc. as of December 31,
1996 have been prepared on the basis that Erols Internet, Inc. operated as a
separately incorporated company and accordingly, reflect the shares of Common
Stock issued to the former stockholder of OEO, Inc. as a result of the
reincorporation and recapitalization of Erols Internet, Inc. Additionally, the
statements of operations for the period from August 1, 1995 (inception) to
December 31, 1995 and for the period from January 1, 1996 to December 28, 1996
have been prepared from the historical books and records of the Internet
division and include all amounts directly attributable and identifiable to the
Internet business as well as indirect expenses, such as physical operating costs
and management salaries. The physical operating costs and management salaries
were charged based on square feet and hours attributable to the Internet
business, respectively.

     The Company has experienced operating losses since its inception as a
result of efforts to build its network infrastructure, increase internal
staffing, develop its systems and expand into new markets. The Company expects
to continue to focus on increasing its subscriber base and geographic coverage.
Accordingly, the Company expects its cost and operating expenses and capital
expenditures to continue to increase significantly, all of which will have a
negative impact on short-term operating results. The online services and
Internet markets are highly competitive. The Company believes that existing
competitors, Internet-based services, Internet service providers, Internet
directory services and telecommunication companies are likely to enhance their
service offerings resulting in greater competition for the Company. The
competitive conditions could have the following effects: require additional
pricing programs, increase spending on marketing, limit the Company's ability to
expand its subscriber base and result in increase attrition in the existing
subscriber base. There can be no assurance that growth in the Company's revenues
or subscriber base will continue or that the Company will be able to achieve or
sustain profitability or positive cash flow.

2.       Summary of Significant Accounting Policies

Use of Estimates

     The preparation of the 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.

Cash and Cash Equivalents

     For purposes of the statements of cash flows, the Company considers all
highly liquid investments with a maturity of three months or less at the time of
purchase to be cash equivalents. On December 31, 1997, the Company had purchased
$5,125,000 of U.S. Government securities under agreements to resell on January
1, 1998. Due to the short-term nature of the agreements, the Company did not
take possession of the securities which were held by the Company's asset
managers. The market value of the securities approximated the carrying amount at
December 31, 1997.

Restricted Cash

     Certain capital lease agreements generally require the Company to maintain
restricted cash deposit accounts with a bank which amounted to $850,166 and
$893,353 as of December 31, 1996 and 1997, respectively.

Impairment of Long-Lived Assets

     At each balance sheet date, management determines whether any property and
equipment or any other assets have been impaired based on the criteria
established in Statement of Financial Accounting Standards No. 121 ("SFAS 121"),
"Accounting for the Impairment of Long-Lived Assets and Long-Lived Assets to be
Disposed of." The Company made no adjustments to the carrying values of the
assets during the period from August 1, 1995 (inception) to December 31, 1995
and during the years ended December 31, 1996 and 1997.

Stock Compensation

     The Company accounts for its stock-based compensation in accordance with
APB No. 25 "Accounting for Stock Issued to Employees" ("APB 25") using the
intrinsic value method. The Company has made pro forma disclosures required by
SFAS No. 123 "Accounting for Stock Based Compensation" ("SFAS 123") using the
fair value method.

Revenue Recognition

     The Company recognizes Internet access revenue when the services are
provided. During the period from August 1, 1995 (inception) to December 31, 1995
and the years ended December 31, 1996 and 1997, the Company offered one, two and
three year contracts for Internet access that are generally paid for in advance
by customers. The Company has deferred recognizing revenue on these advance
payments and amortizes the amounts to revenue on a straight-line basis as the
services are provided.

     The Company allows for cancellations of up to thirty days after service is
initiated for a full refund. Any cancellations in the period subsequent to the
first thirty days of service are refunded on a pro-rata schedule. The Company
reviews its history of cancellations periodically and, when appropriate, records
a reserve for estimated amount of returns.

     The Company recognizes web page hosting revenues when the services are
rendered. During the year ended 1997, the Company offered monthly and one year
contracts to host customers' web pages. The revenues related to these contracts
were recognized on the straight line basis over the term of the contract.
Revenues from internet classes and product sales are recognized as the service
is performed or product shipped.

Costs of Revenues

     Cost of dial access revenues primarily consists of telecommunication
expenses inherent in the network infrastructure. Cost of dial access revenues
also includes fees paid for lease of the Company's backbone, as well as license
fees for Web browser software based on a per user charge, other license fees
paid to third-party software vendors, product costs, and contractor fees for
distribution of software to new subscribers.

Advertising Costs

     All advertising and promotion costs are expensed as incurred. During the
period from August 1, 1995 (inception) to December 31, 1995 and for the years
ended December 31, 1996 and 1997, the Company expensed $121,451, $6,530,877 and
$12,267,445, respectively, as advertising costs.

Income Taxes

     Prior to December 28, 1996, the Internet Business operated as a division of
OEO, Inc. and accordingly, a consolidated tax return for OEO, Inc. was filed.
Since OEO, Inc. generated consolidated net losses for the period from August 1,
1995 to December 28, 1996, no provision for income taxes would have been
recorded for the consolidated company and, as such, no additional disclosure has
been made as to the Internet division's portion of the net losses for tax
purposes. In connection with the reincorporation of OEO, Inc. and the spin-off
of Erol's Computer & TV/VCR, Inc., the provision for income taxes and the
resulting deferred tax asset (see Note 8) for the Company using the liability
method was calculated for the period December 2, 1996 through December 31, 1996.
There was no provision for income taxes required for this period.

Financial Instruments and Concentration of Credit Risk

     Financial instruments that potentially subject the Company to
concentrations of credit risk consist primarily of cash, restricted cash and
accounts receivable. The cash and restricted cash are held by a high credit
quality financial institution. For accounts receivable, the Company performs
ongoing credit evaluations of its customers' financial condition and generally
does not require collateral. The Company maintains reserves for credit losses,
and such losses have been within management's expectations. The concentration of
credit risk is mitigated by the large customer base.  The carrying amount of
the receivables approximates their fair value.

Sources of Supplies

     The Company relies on local telephone companies and other companies to
provide data communications. Although management feels alternative
telecommunications facilities could be found in a timely manner, any disruption
of these services could have an adverse effect on operating results. Although
the Company attempts to maintain multiple vendors for each required product, its
modems, terminal servers, and high-performance routers, which are important
components of its network, are currently acquired from two sources. In addition,
some of the Company's suppliers have limited resources and production capacity.
If the suppliers are unable to meet the Company's needs as it builds out its
network infrastructure, then delays and increased costs in the expansion of the
Company's network infrastructure could result, which would affect operating
results adversely.

Recent Pronouncements

     In June 1997, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 130 ("SFAS 130"), "Comprehensive Income",
which is required to be adopted for the year ended December 31, 1998. SFAS 130
requires that an enterprise (a) classify items of other comprehensive income by
their nature in the financial statements and (b) display the accumulated balance
of other comprehensive income separately from retained earnings and additional
paid-in capital in the Statements of Stockholders' Deficit. The Company will be
required to restate earlier periods provided for comparative purposes. The
disclosure for comprehensive income is not expected to be material.

3.       Property and Equipment

     Property and equipment, including leasehold improvements, are stated at
cost. Depreciation is calculated using the straight-line method over estimated
useful lives ranging between three and seven years. Leasehold improvements are
amortized over the lesser of the related lease term or the useful life.

     Property and equipment consisted of the following:

4.   Notes Payable

     Pursuant to a promissory note agreement dated December 20, 1995, the
Company owed $500,000 to a financial institution as of December 31, 1995. The
loan bore interest at an annual rate of 1.5% plus prime rate (10% at December
31, 1995). Prior to the repayment of the loan balance, the loan was
collateralized by certain assets of the Company and was guaranteed by an officer
and stockholder of the Company. During 1996, the Company repaid the balance of
the note plus unpaid interest totaling $16,131.

     As of December 31, 1996 and 1997, the Company had a short-term line of
credit arrangement with a bank which allowed for aggregate borrowings up to
$700,000. As of December 31, 1996 and 1997, $700,000 was outstanding under this
arrangement. The line of credit bears interest at the bank prime rate plus
1-1/2% per annum (10% as of December 31, 1997). As of December 31, 1996 and
1997, the Company has accrued $2,051 and $7,158, respectively, of interest
related to this line of credit. The note is due on September 25, 1998. The line
of credit is personally guaranteed by an officer and stockholder of the Company.
See Note 6.

     During December 1997, the Company entered into a subordinated revolving
line of credit agreement, with a maximum borrowing amount of $5,000,000, and a
$5,000,000 subordinated note payable agreement with a stockholder. The Company
received the proceeds from the $5,000,000 note payable in December 1997 and
utilized the proceeds to repay certain accounts payable. The subordinated
revolving line of credit and note payable bear interest at a fluctuating rate
equal to the greater of 11% per annum or 4-1/2 per annum over the prime rate.
The subordinated revolving line of credit agreement provides for an unused
facility fee equal to 1/2% of the difference between the average daily balance
outstanding and the $5,000,000 maximum borrowing amount, payable quarterly. The
revolving line of credit and the note payable are secured by certain assets of
the Company. The balance of the note payable, as well as any outstanding
borrowings under the line of credit facility, are due upon the acquisition of
more than 50% of the Company's outstanding Common Stock or the sale in an
underwritten public offering of debt or equity securities issued by the Company.

5.   Commitments

Operating Leases

     The Company leases office space and various office and computer equipment
under non-cancellable operating lease agreements. The leases generally provide
for renewal terms and the Company is required to pay a portion of the common
areas' expenses including maintenance, real estate taxes and other expenses.
Rent expense for the period from August 1, 1995 (inception) to December 31, 1995
and for the years ended December 31, 1996 and 1997, was $12,601, $843,615 and
$2,236,183, respectively. The Company is also required to pay additional rent
based on certain percentages of revenues recorded by the various stores (kiosks)
when the revenues exceed certain predetermined amounts. The Company has not
incurred any significant additional rent charges to date.

     As of December 31, 1997, payments due under non-cancellable operating
leases are as follows:

          1998................................    $   1,301,609

Capital Leases

     The Company leases certain office and computer equipment as a result of
sales-leaseback agreements, which will be accounted for as capital leases. The
Company recorded approximately $192,000 of deferred gain related to the
difference between the sale price of the equipment and present value of the
minimum lease payments. The Company will amortize the deferred gain to other
income over the lease term. Computer equipment held under capital leases at
December 31, 1996 and 1997 amounted to $1,956,407 and $4,320,349, respectively.
Accumulated amortization related to this equipment amounted to $480,384 and
$1,329,551 at December 31, 1996 and 1997, respectively. Amortization related to
capital leased equipment is included in depreciation and amortization expense.
The non-cash portion of these transactions has been excluded from the Statements
of Cash Flows.

     As of December 31, 1997, future minimum lease payments under the capital
leases are as follows:


1998...............................................    $    1,805,933

Letters of Credit

     During 1996 and 1997, in connection with capital lease agreements, the
Company obtained several letters of credit with a financial institution in the
amounts of the lease obligations. As collateral for these letters of credit, the
financial institution required that the Company invest certain amounts in
certificate of deposits at the financial institution. The total amount of cash
restricted in connection with these letters of credit is approximately $905,000
and $837,000 at December 31, 1996 and 1997, respectively. The certificates of
deposit bear interest at a rate of 4.7%, mature in one year and are renewable at
the option of the financial institution. The letters of credit expire in 1998
and will be automatically renewed, subject to certain withdrawal privileges by
the Company, by the financial institution for an additional one year period for
each year under which the capital lease obligations are outstanding.

Employment Agreements

     During 1996 and 1997, the Company executed employment agreements with
certain key executives under which the Company is required to pay the following
base salaries annually over the next two years:


1998......................................     $      840,000
1999......................................            225,000

Other Commitments

     Effective January 31, 1997, the Company entered into an ISP License
Agreement with a vendor. The Company agreed to license a minimum of 1,000,000
software mailbox products in exchange for $3,000,000, which is to be paid in
quarterly installments over the next three years. After exceeding the 1,000,000
software mail box products, the Company may license additional mailbox products
for a fee of $3.00 per mailbox.

6.   Related Party Transactions

     Since inception, the Company has shared common facilities and operating
costs such as executive management salaries, accounting, supplies, marketing,
etc., with Erol's Computer & TV/VCR, Inc. (the "Affiliated Company") which
shares common ownership with the Company. During the period from August 1, 1995
(inception) to December 31, 1995 and the years ended December 31, 1996 and 1997,
$11,530, $721,557 and $0 were charged to operations related to shared facilities
and operating costs, respectively.

     The Company executed a promissory note agreement with an Individual (the
"Individual"), an officer and stockholder of the Company, and the Affiliated
Company, whereby the Company agreed to loan $350,000 to the Individual and the
Affiliated Company. The note bears annual interest at a rate equivalent to the
federal rate, defined by the Internal Revenue Code. The balance of the note plus
compounded interest will become due to the Company three weeks after the date on
which the short-term line of credit arrangement expires and the Individual has
been released as a guarantor of the line of credit arrangement with the bank.

     Since inception in August 1995 through December 31, 1996, Erols Internet
paid certain expenses related to the Affiliated Company on behalf of the
Affiliated Company. These expenses amounted to $658,422 and $1,645,511 during
the period from August 1, 1995 (inception) to December 31, 1995 and during the
year ended December 31, 1996, respectively. Since there is no intention to repay
these amounts to the Company, the Company has written off the receivable and has
included the amount in other expense in the Statements of Operations.

     Effective January 1, 1997, the Company entered into a five year management
agreement with Erol's Computer & VCR (the "Affiliated Company"). Pursuant to
this agreement, the Company will provide office space, general and
administrative services, sales services and print advertising services to the
Affiliated Company in exchange for a management fee. The management fee is based
on actual direct labor charges to the Affiliated Company and an allocation of
facilities costs based on square feet used by the Affiliated Company. During the
year ended December 31, 1997, the management fee amounted to $58,784. The
$58,784 is included in accounts receivable as of December 31, 1997. During
December 1997, the parties agreed to terminate the agreement effective December
31, 1997.

     The Company purchased computer equipment for resale and internal use from
the Affiliated Company. During the year ended December 31, 1997, purchases
amounted to $532,714.

7.   Stockholders' Deficit

Equity transactions

     During 1995, the Company operated as a division of OEO, Inc. and
accordingly, had no Common Stock outstanding. During 1996, as a part of the
reorganization, the sole common stockholder was issued 4,272,023 shares of
voting Common Stock, par value $0.001 in Erols Internet, Inc.

     In December 1996, the Company completed a private placement to raise total
proceeds of approximately $3,000,000 from an outside investor (the "Minority
Stockholder"). The Company sold 1,314,469 shares of voting Common Stock at $2.29
per share.

     In May 1997, the Company completed a private placement to raise total
proceeds of approximately $500,000 from the Minority Stockholder. The Company
sold 131,447 shares of voting Common Stock at $3.80 per share.

     In September 1997, the Company completed a private placement to raise total
proceeds of approximately $500,000 from the Minority Stockholder. The Company
sold 114,600 shares of voting Common Stock at $4.36 per share.

     On December 4, 1997, the Board of Directors and stockholders of the Company
approved a 1 for 2.3583672 reverse stock split of the Company's $0.001 par value
voting Common Stock, which became effective on December 5, 1997. In addition,
the Company eliminated the authorized non-voting Common Stock. All references in
the accompanying financial statements to the number of shares of Common Stock
and per-share amounts have been restated to reflect these transactions.

Stock Option Plan

     During 1996, the Company adopted a stock option plan (the "Option Plan")
which permits the Company to grant up to 657,234 voting Common Stock options to
employees, board members and others who contribute materially to the success of
the Company. During 1997, the Company increased the number of options available
for grant under the plan to 826,843. Stock options are generally granted at
prices which the Company's Board of Directors believes approximates the fair
market value of its Common Stock at the date of grant. Individual grants
generally become exercisable ratably over a period of three years from the date
of hire. The contractual term of the options is ten years from the date of
grant.

     In December 1996, the Company issued 328,617 options to a certain officer
at an exercise price of $1.18 which was considered to be below fair market value
at the time of the option grant. Accordingly, the Company recorded deferred
stock compensation of $364,250 which will be amortized to expense over the
vesting period of three years beginning in January 1997, of which $161,889 was
recognized as expense during 1997.


     Common stock option activity was as follows:

     Had compensation expense related to the stock option plan been determined
based on the fair value at the grant date for options granted during the period
from August 1, 1995 to December 31, 1995 and for the years ended December 31,
1996 and 1997 consistent with the provisions of SFAS 123, the Company's net loss
would have been as follows:

     The effect of applying SFAS 123 on 1995, 1996 and 1997 pro forma net loss
as stated above is not necessarily representative of the effects on reported net
loss for future years due to, among other things, the vesting period of the
stock options and the fair value of additional stock options in future years.

     The fair value of each option grant is estimated on the date of grant using
the Black-Scholes option-pricing fair value model with the following
weighted-average assumptions used for grants in 1996 and 1997: dividend yield of
0%, expected volatility of 70%; risk-free interest rate of 6.5%; and expected
terms from 3 to 4 years. The weighted average fair values of the options granted
in 1996 and 1997 with a stock price equal to the exercise price is $1.31 and
$1.79, respectively. The weighted average fair value of the options granted in
1996 with a stock price greater than the exercise price in 1996 is $0.38.

9.   Contingencies

     On September 1, 1997, a motion for judgment was filed against the Company
in Virginia state court by the Company's former Vice President, Marketing. The
motion for judgment alleges breach of contract and wrongful termination and
seeks punitive and compensatory damages of approximately $1,000,000.
Additionally, the Company's former Vice President, Marketing seeks to exercise
certain stock options. Discovery has just been initiated and, therefore, it is
premature to reach an opinion on liability or the extent of exposure. However,
the Company believes that it has a meritorious defense and is conducting a
vigorous defense. The Company doesn't believe that the conclusion of this matter
will materially affect the Company's financial position or results of
operations.

10.  Subsequent Event

     On January 21, 1998, the Company entered into an Agreement and Plan of
Merger with RCN Corporation ("RCN"). In the transaction, RCN will issue common
stock and replacement stock options valued at $48,500,000 and pay $35,000,000 in
cash, including the assumption and repayment of the $5,700,000 note payable, in
exchange for all of the outstanding equity securities of Erols Internet, Inc.
The Agreement and Plan of Merger was closed on February 20, 1998.

     In conjunction with the merger agreement with RCN, certain outstanding
options held by two employees of the Company became fully vested. Additionally,
all outstanding options held by non-employees will fully vest and be repurchased
by the Company at a price equal to the difference between $14 and the option
exercise price multiplied by the number of outstanding options.

                  INFORMATION NOT REQUIRED IN PROSPECTUS


Item 20.  Indemnification of Directors and Officers

               Reference is made to Section 102(b)(7) of the Delaware General
Corporation Law (the "DGCL"), which enables a corporation in its original
certificate of incorporation or an amendment thereto to eliminate or limit the
personal liability of a director for violations of the director's fiduciary
duty, except (i) for any breach of the director's duty of loyalty to the
corporation or it stockholders, (ii) for acts or omissions not in good faith
or which involve intentional misconduct or a knowing violation of law, (iii)
pursuant to Section 174 of the DGCL (providing for liability of directors for
the unlawful payment of dividends or unlawful stock purchases or redemptions)
or (iv) for any transaction from which a director derived an improper personal
benefit.

               Section 145 of the DGCL empowers the Company to indemnify,
subject to the standards set forth therein, any person in connection with any
action, suit or proceeding brought before or threatened by reason of the fact
that the person was a director, officer, employee or agent of such company, or
is or was serving as such with respect to another entity at the request of
such company.  The DGCL also provides that the Company may purchase insurance
on behalf of any such director, officer, employee or agent.

               The Company's Amended and Restated Articles of Incorporation
provides in effect for the indemnification by the Company of each director and
officer of the Company to the fullest extent permitted by applicable law.

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.

              (2) For the purpose of determining any liability under the
Securities Act of 1933, each post-effective amendment shall be deemed to be a
new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial
bona fide offering thereof.

              (3) To remove from registration by means of a post-effective
amendment any of the securities being registered which remain unsold at the
termination of the offering.

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

              (c) 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.

              (d) 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.

amount of all Notes outstanding at the time of the offer to purchase or repay

or the aggregate accreted value, as the case may be, of all other Indebtedness

Notes theretofore authenticated and delivered under this Indenture, except:

                  (a) Notes theretofore canceled by the Trustee or delivered to
         the Trustee for cancellation;

                  (b) Notes, or portions thereof, for whose payment or

         with the Trustee or any Paying Agent (other than the Company or any

         Company or any Affiliate thereof (if the Company or such Affiliate
         shall act as Paying Agent) for the Holders of such Notes; provided,
         however, that if such Notes are to be redeemed, notice of such
         redemption has been duly given pursuant to this Indenture or provision
         therefor satisfactory to the Trustee has been made;

                  (c) Notes with respect to which the Company has effected
         defeasance or covenant defeasance as provided in Article Four, to the
         extent provided in Sections 4.02 and 4.03 hereof; and

                  (d) Notes in exchange for or in lieu of which other Notes have
         been authenticated and delivered pursuant to this Indenture, other than
         any such Notes in respect of which there shall have been presented to

         fide purchaser in whose hands the Notes are valid obligations of the
         Company;

provided, however, that in determining whether the Holders of the requisite
principal amount of Outstanding Notes have given any request, demand,
authorization, direction, notice, consent or waiver hereunder, Notes owned by
the Company or any other obligor upon the Notes or any Affiliate of the Company
or such other obligor shall be disregarded and deemed not to be Outstanding,
except that, in determining whether the Trustee shall be protected in relying
upon any such request, demand, authorization, direction, notice, consent or

owned which have been pledged in good faith may be regarded as Outstanding if
the pledgee establishes to the satisfaction of the Trustee the pledgee's right
so to act with respect to such Notes and that the pledgee is not the Company or
any other obligor upon the Notes or any Affiliate of the Company or such other
obligor. If the Paying Agent holds, in its capacity as such, on any Maturity
Date or on any optional redemption date money sufficient to pay all accrued
interest and principal with respect to such Notes payable on that date and is
not prohibited from paying such money to the Holders thereof pursuant to the
terms of this Indenture, then on and after that date such Notes cease to be
Outstanding and interest on them ceases to accrue. Notes may also cease to be
Outstanding to the extent expressly provided in Article Four.

                  Section 1.03. Rules of Construction.

                  For all purposes of this Indenture, except as otherwise
expressly provided or unless the context otherwise requires:

                  (a) the terms defined in this Article have the meanings
assigned to them in this Article, and include the plural as well as the
singular;

                  (b) all other terms used herein which are defined in the Trust
Indenture Act, either directly or by reference therein, have the meanings
assigned to them therein;

                  (c) all accounting terms not otherwise defined herein have the
meanings assigned to them in accordance with GAAP;

                  (d) the words "herein," "hereof" and "hereunder" and other
words of similar import refer to this Indenture as a whole and not to any
particular Article, Section or other subdivision;

                  (e) all references to "$" or "dollars" refer to the lawful
currency of the United States of America; and

                  (f) the words "include," "included" and "including" as used
herein are deemed in each case to be followed by the phrase "without
limitation."

                  Section 1.04. Form of Documents Delivered to Trustee.

                  In any case where several matters are required to be certified
by, or covered by an opinion of, any specified person, it is not necessary that
all such matters be certified by, or covered by the opinion of, only one such
person, or that they be so certified or covered by only one document, but one
such person may certify or give an opinion with respect to some matters and one
or more other persons as to other matters, and any such person may certify or
give an opinion as to such matters in one or several documents.

                  Any certificate or opinion of an officer of the Company may be
based, insofar as it relates to legal matters, upon a certificate or opinion of,
or representations by, counsel, unless such officer knows, or in the exercise of
reasonable care should know, that the certificate or opinion or representations
with respect to the matters upon which his certificate or opinion is based are
erroneous. Any such certificate or opinion may be based, insofar as it relates
to factual matters, upon a certificate or opinion of, or representations by, an
officer or officers of the Company stating that the information with respect to
such factual matters is in the possession of the Company, unless such counsel
knows, or in the exercise of reasonable care should know, that the certificate
or opinion or representations with respect to such matters are erroneous.

                  Where any person is required to make, give or execute two or
more applications, requests, consents, certificates, statements, opinions or
other instruments under this Indenture, they may, but need not, be consolidated,
with proper identification of each matter covered therein, and form one
instrument.

                  Section 1.05. Acts of Holders.

                  (a) Any request, demand, authorization, direction, notice,
consent, waiver or other action provided by this Indenture to be given or taken
by Holders may be embodied in and evidenced by one or more instruments of
substantially similar tenor signed by such Holders in person or by an agent duly
appointed in writing; and, except as herein otherwise expressly provided, such
action shall become effective when such instrument or instruments are delivered
to the Trustee and, where it is hereby expressly required, to the Company. Such
instrument or instruments (and the action embodied therein and evidenced
thereby) are herein sometimes referred to as the "Act" of the Holders signing
such instrument or instruments. Proof of execution (as provided below in
subsection (b) of this Section 1.05) of any such instrument or of a writing
appointing any such agent shall be sufficient for any purpose of this Indenture
and (subject to Section 6.01 hereof) conclusive in favor of the Trustee and the
Company, if made in the manner provided in this Section.

                  (b) The fact and date of the execution by any person of any
such instrument or writing may be proved in any reasonable manner which the
Trustee deems sufficient.

                  (c) The ownership of Notes shall be proved by the Note
Register.

                  (d) Any request, demand, authorization, direction, notice,
consent, waiver or other action by the Holder of any Note shall bind every
future Holder of the same Note or the Holder of every Note issued upon the
transfer thereof or in exchange therefor or in lieu thereof to the same extent
as the original Holder, in respect of anything done, suffered or omitted to be
done by the Trustee, any Paying Agent or the Company in reliance thereon,
whether or not notation of such action is made upon such Note.

                  Section 1.06. Notices, etc., to the Trustee and the Company.

                  Any request, demand, authorization, direction, notice,
consent, waiver or Act of Holders or other document provided or permitted by
this Indenture to be made upon, given or furnished to, or filed with:

                  (a) the Trustee by any Holder or by the Company shall be
sufficient for every purpose hereunder if made, given, furnished or filed, in
writing, to or with the Trustee at the Corporate Trust Office, 450 West 33rd
Street, 15th Floor, New York, New York 10001, Attention: Global Trust Services
or at any other address previously furnished in writing to the Holders and the
Company by the Trustee; or

                  (b) the Company by the Trustee or by any Holder shall be
sufficient for every purpose (except as otherwise expressly provided herein)
hereunder if in writing and mailed, first-class postage prepaid, to the Company
addressed to it at RCN Corporation, 105 Carnegie Center, Princeton, New Jersey,
08540-6215, Attention: Chief Executive Officer, or at any other address
previously furnished in writing to the Trustee by the Company.

                  Section 1.07. Notice to Holders; Waiver.

                  Where this Indenture provides for notice to Holders of any
event, such notice shall be sufficiently given (unless otherwise expressly
provided herein) if in writing and mailed, first-class postage prepaid, to each
Holder affected by such event, at the address of such Holder as it appears in
the Note Register, not later than the latest date, and not earlier than the
earliest date, prescribed for the giving of such notice. In any case where
notice to Holders is given by mail, neither the failure to mail such notice, nor
any defect in any notice so mailed, to any particular Holder shall affect the
sufficiency of such notice with respect to other Holders. Any notice when mailed
to a Holder in the aforesaid manner shall be conclusively deemed to have been
received by such Holder whether or not actually received by such Holder. Where
this Indenture provides for notice in any manner, such notice may be waived in
writing by the person entitled to receive such notice, either before or after
the event, and such waiver shall be the equivalent of such notice. Waivers of
notice by Holders shall be filed with the Trustee, but such filing shall not be
a condition precedent to the validity of any action taken in reliance upon such
waiver.

                  In case by reason of the suspension of regular mail service or
by reason of any other cause, it shall be impracticable to mail notice of any
event as required by any provision of this Indenture, then any method of giving
such notice as shall be satisfactory to the Trustee shall be deemed to be a
sufficient giving of such notice.

                  Section 1.08. Conflict with Trust Indenture Act.

                  If any provision hereof limits, qualifies or conflicts with
any provision of the Trust Indenture Act or another provision which is required
or deemed to be included in this Indenture by any of the provisions of the Trust
Indenture Act, such provision or requirement of the Trust Indenture Act shall
control.

                  If any provision of this Indenture modifies or excludes any
provision of the Trust Indenture Act that may be so modified or excluded, the
latter provision shall be deemed to apply to this Indenture as so modified or
excluded, as the case may be.

                  Section 1.09. Effect of Headings and Table of Contents.

                  The Article and Section headings herein and the Table of
Contents are for convenience only and shall not affect the construction hereof.

                  Section 1.10. Successors and Assigns.

                  All covenants and agreements in this Indenture by the Company
shall bind its successors and assigns, whether so expressed or not.

                  Section 1.11. Separability Clause.

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

                  Section 1.12. Benefits of Indenture.

                  Nothing in this Indenture or in the Notes issued pursuant
hereto, express or implied, shall give to any person (other than the parties
hereto and their successors hereunder, any Paying Agent and the Holders) any
benefit or any legal or equitable right, remedy or claim under this Indenture.

                  Section 1.13. GOVERNING LAW.

                  THIS INDENTURE AND THE NOTES SHALL BE GOVERNED BY, AND
CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK WITHOUT GIVING
EFFECT TO PRINCIPLES OF CONFLICTS OF LAW.

                  Section 1.14. No Recourse Against Others.

                  A director, officer, employee or stockholder, as such, of the
Company shall not have any liability for any obligations of the Company under
the Notes or this Indenture or for any claim based on, in respect of or by
reason of such obligations or their creation.

                  Section 1.15. Independence of Covenants.

                  All covenants and agreements in this Indenture shall be given
independent effect so that if a particular action or condition is not permitted
by any of such covenants, the fact that it would be permitted by an exception
to, or be otherwise within the limitations of, another covenant shall not avoid
the occurrence of a Default if such action is taken or condition exists.

                  Section 1.16. Exhibits.

                  All exhibits attached hereto are by this reference made a part
hereof with the same effect as if herein set forth in full.

                  Section 1.17. Counterparts.

                  This Indenture may be executed in any number of counterparts
and by telecopier, each of which shall be an original; but such counterparts
shall together constitute but one and the same instrument.

                  Section 1.18. Duplicate Originals.

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

                                   ARTICLE TWO

                                   NOTE FORMS

                  Section 2.01. Form and Dating.

                  The Notes and the Trustee's certificate of authentication with
respect thereto shall be in substantially the forms set forth, or referenced, in
Exhibit A-1 and Exhibit A-2, respectively, annexed hereto, with such appropriate
insertions, omissions, substitutions and other variations as are required or
permitted by this Indenture and may have such letters, numbers or other marks of
identification and such legends or endorsements placed thereon as may be
required to comply with any applicable law or with the rules of the Depository,
any clearing agency or any securities exchange or as may, consistently herewith,
be determined by the officers executing such Notes, as evidenced by their
execution thereof.

                  The definitive Notes shall be printed, typewritten,
lithographed or engraved or produced by any combination of these methods or may
be produced in any other manner permitted by the rules of any securities
exchange on which the Notes may be listed, all as determined by the officers
executing such Notes, as evidenced by their execution of such Notes.

                  Each Note shall be dated the date of its issuance and shall
show the date of its authentication. The terms and provisions contained in the
Notes shall constitute, and are expressly made, a part of this Indenture.

                                  ARTICLE THREE

                                    THE NOTES

                  Section 3.01. Title and Terms.

                  The aggregate principal amount at maturity of the Notes which
may be authenticated and delivered under this Indenture is limited to
$567,000,000, except for Notes authenticated and delivered upon registration of
transfer of, or in exchange for, or in lieu of, other Notes pursuant to Section
3.03, 3.04, 3.05, 3.06, 9.06, 10.10 or 10.15 hereof.

                  The Notes will mature on February 15, 2008. The Notes shall be
issued at a discount to yield gross proceeds of $350,587,440. The Notes shall
not bear cash interest prior to February 15, 2003. Commencing on August 15,
2003, interest on the Notes will be payable in cash at a rate of 9.80% per
annum, semi-annually in arrears from the most recent Interest Payment Date to
which interest has been paid or, if no interest has been paid from February 15,
2003. Interest on any overdue principal, interest (to the extent lawful) or
premium, if any, shall be payable on demand.

                  Section 3.02. Registrar and Paying Agent.

                  The Company shall maintain an office or agency (which shall be
located in the Borough of Manhattan in The City of New York, State of New York)
where Notes may be presented for registration of transfer or for exchange (the
"Registrar"), an office or agency (which shall be located in the Borough of
Manhattan in The City of New York, State of New York) where Notes may be
presented for payment (the "Paying Agent" or "Agent") and an office or agency
where notices and demands to or upon the Company in respect of the Notes and
this Indenture may be served. The Registrar shall keep a register of the Notes
and of their transfer and exchange. The Company may have one or more
co-registrars and one or more additional paying agents. The term "Paying Agent"
or "Agent" includes any additional paying agent. The Company may act as its own
Paying Agent, except for the purposes of payments on account of principal on the
Notes pursuant to Sections 10.10 and 10.15 hereof.

                  The Company shall enter into an appropriate agency agreement
with any Agent not a party to this Indenture, which shall incorporate the
provisions of the Trust Indenture Act. The agreement shall implement the
provisions of this Indenture that relate to such Agent. The Company shall notify
the Trustee of the name and address of any such Agent. If the Company fails to
maintain a Registrar or Paying Agent, or fails to give the foregoing notice, the
Trustee shall act as such and shall be entitled to appropriate compensation in
accordance with Section 6.07 hereof.

                  The Company initially appoints the Trustee as the Registrar
and Paying Agent and agent for service of notices and demands in connection with
the Notes.

                  Section 3.03. Execution and Authentication.

                  The Initial Notes and the Trustee's certificate of
authentication shall be substantially in the form of Exhibit A-1 hereto. The
Exchange Notes and the Trustee's certificate of authentication relating thereto
shall be substantially in the form of Exhibit A-2 hereto. The Notes may have
notations, legends or endorsements required by law, stock exchange rule or
usage. The Company shall approve the form of the Notes and any notation, legend
or endorsement thereon. Each Note shall be dated the date of issuance and shall
show the date of its authentication.

                  The terms and provisions contained in the Notes annexed hereto
as Exhibits A-1 and A-2 shall constitute, and are hereby expressly made, a part
of this Indenture and, to the extent applicable, 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.

                  Notes offered and sold in reliance on Rule 144A and Notes
offered and sold in reliance on Regulation S shall be issued initially in the
form of one or more Global Notes, substantially in the form set forth in Exhibit
A-1, deposited with the Trustee, as custodian for the Depository, duly executed
by the Company and authenticated by the Trustee as hereinafter provided and
shall bear the legend set forth in Exhibit B. The aggregate principal amount of
the Global Notes may from time to time be increased or decreased by adjustments
made on the records of the Trustee, as custodian for the Depository, as
hereinafter provided.

                  Notes issued in exchange for interests in a Global Note
pursuant to Section 3.17 hereof may be issued in the form of permanent
certificated Notes in registered form in substantially the form set forth in
Exhibit A-1 (the "Physical Notes").

                  Two Officers, or an Officer and an Assistant Secretary, shall
sign, or one Officer shall sign, and one Officer or an Assistant Secretary (each
of whom shall, in each case, have been duly authorized by all requisite
corporate actions) shall attest to, the Notes for the Company by manual or
facsimile signature.

                  If an Officer or Assistant Secretary whose signature is on a
Note was an Officer or Assistant Secretary at the time of such execution but no
longer holds that office or position at the time the Trustee authenticates the
Note, the Note shall nevertheless be valid.

                  The Trustee shall authenticate (i) Initial Notes for aggregate
principal amount of the Notes at maturity not to exceed $567,000,000 at any
time, (ii) Private Exchange Notes from time to time only in exchange for a like
principal amount of Initial Notes and (iii) Unrestricted Notes from time to time
only in exchange for (A) a like principal amount of Initial Notes or (B) a like
principal amount of Private Exchange Notes, in each case upon a written order of
the Company in the form of an Officers' Certificate of the Company. Each such
written order shall specify the amount of Notes to be authenticated and the date
on which the Notes are to be authenticated, whether the Notes are to be Initial
Notes, Private Exchange Notes or Unrestricted Notes and whether (subject to this
Section 3.03) the Notes are to be issued as Physical Notes or Global Notes and
such other information as the Trustee may reasonably request. The aggregate
principal amount of the Notes at maturity outstanding at any time may not exceed
$567,000,000, except as provided in Section 3.06 hereof.

                  Notwithstanding the foregoing, all Notes issued under this
Indenture shall vote and consent together on all matters (as to which any of
such Notes may vote or consent) as one class and no series of Notes will have
the right to vote or consent as a separate class on any matter.

                  The Trustee may appoint an authenticating agent reasonably
acceptable to the Company to authenticate Notes. Unless otherwise provided in
the appointment, an authenticating agent may authenticate Notes whenever the
Trustee may do so. Each reference in this Indenture to authentication by the
Trustee includes authentication by such agent. An authenticating agent has the
same rights as an Agent to deal with the Company and Affiliates of the Company.

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

                  Section 3.04. Temporary Notes.

                  Until definitive Notes are prepared and ready for delivery,
the Company may execute and upon a Company Order the Trustee shall authenticate
and deliver temporary Notes. Temporary Notes shall be substantially in the form
of definitive Notes, in any authorized denominations, but may have variations
that the Company reasonably considers appropriate for temporary Notes as
conclusively evidenced by the Company's execution of such temporary Notes.

                  If temporary Notes are issued, the Company will cause
definitive Notes to be prepared without unreasonable delay but in no event later
than the date that the Exchange Offer is consummated. After the preparation of
definitive Notes, the temporary Notes shall be exchangeable for definitive Notes
upon surrender of the temporary Notes at the office or agency of the Company
designated for such purpose pursuant to Section 10.02 hereof, without charge to
the Holder. Upon surrender for cancellation of any one or more temporary Notes,
the Company shall execute and the Trustee shall authenticate and deliver in
exchange therefor a like principal amount of definitive Notes of like tenor and
of authorized denominations. Until so exchanged the temporary Notes shall in all
respects be entitled to the same benefits under this Indenture as definitive
Notes.

                  Section 3.05. Transfer and Exchange.

                  The Company shall cause to be kept at the Corporate Trust
Office of the Trustee a register (the register maintained in such office and in
any other office or agency designated pursuant to Section 10.02 hereof being
sometimes referred to herein as the "Note Register") in which, subject to such
reasonable regulations as the Registrar may prescribe, the Company shall provide
for the registration of Notes and of transfers and exchanges of Notes. The
Trustee is hereby initially appointed Registrar for the purpose of registering
Notes and transfers of Notes as herein provided.

                  When Notes are presented to the Registrar or a co-Registrar
with a request from the Holder of such Notes to register the transfer or
exchange for an equal principal amount of Notes of other authorized
denominations, the Registrar shall register the transfer or make the exchange as
requested; provided, however, that every Note presented or surrendered for
registration of transfer or exchange shall be duly endorsed or be accompanied by
a written instrument of transfer or exchange in form satisfactory to the Company
and the Registrar, duly executed by the Holder thereof or his attorney duly
authorized in writing. Whenever any Notes are so presented for exchange, the
Company shall execute, and the Trustee shall authenticate and deliver, the Notes
which the Holder making the exchange is entitled to receive. No service charge
shall be made to the Noteholder for any registration of transfer or exchange.
The Company may require from the Noteholder payment of a sum sufficient to cover
any transfer taxes or other governmental charge that may be imposed in relation
to a transfer or exchange, but this provision shall not apply to any exchange
pursuant to Section 10.10, 10.15 or 9.06 hereof (in which events the Company
will be responsible for the payment of all such taxes which arise solely as a
result of the transfer or exchange and do not depend on the tax status of the
Holder). The Trustee shall not be required to exchange or register the transfer
of any Note for a period of 15 days immediately preceding the first mailing of
notice of redemption of Notes to be redeemed or of any Note selected, called or
being called for redemption except, in the case of any Note where public notice
has been given that such Note is to be redeemed in part, the portion thereof not
to be redeemed.

                  All Notes issued upon any registration of transfer or exchange
of Notes shall be the valid obligations of the Company, evidencing the same
Indebtedness, and entitled to the same benefits under this Indenture, as the
Notes surrendered upon such registration of transfer or exchange.

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

                  Section 3.06. Mutilated, Destroyed, Lost and Stolen Notes.

                  If a mutilated Note is surrendered to the Trustee or if the
Holder of a Note of any series claims that the Note has been lost, destroyed or
wrongfully taken, the Company shall execute and upon a Company Order, the
Trustee shall authenticate and deliver a replacement Note of like tenor and
principal amount, bearing a number not contemporaneously outstanding if the
Holder of such Note furnishes to the Company and to the Trustee evidence
reasonably acceptable to them of the ownership and the destruction, loss or
theft of such Note and an indemnity bond shall be posted by such Holder,
sufficient in the judgment of the Company or the Trustee, as the case may be, to
protect the Company, the Trustee or any Agent from any loss that any of them may
suffer if such Note is replaced. The Company may charge such Holder for the
Company's expenses in replacing such Note (including (i) expenses of the Trustee
charged to the Company and (ii) any tax or other governmental charge that may be
imposed) and the Trustee may charge the Company for the Trustee's expenses in
replacing such Note.

                  Every replacement Note issued pursuant to this Section in lieu
of any destroyed, lost or stolen Note shall constitute an original additional
contractual obligation of the Company, whether or not the destroyed, lost or
stolen Note shall be at any time enforceable by anyone, and shall be entitled to
all benefits of this Indenture equally and proportionately with any and all
other Notes duly issued hereunder.

                  The provisions of this Section are exclusive and shall
preclude (to the extent lawful) all other rights and remedies with respect to
the replacement or payment of mutilated, destroyed, lost or stolen Notes.

                  Section 3.07. Payment of Interest; Interest Rights Preserved.

                  Interest on any Note which is payable, and is punctually paid
or duly provided for, on any Interest Payment Date shall be paid to the person
in whose name that Note (or one or more Predecessor Notes) is registered at the
close of business on the Regular Record Date for such interest.

                  Any interest on any Note which is payable, but is not
punctually paid or duly provided for, on any Interest Payment Date and interest
on such defaulted interest at the then applicable interest rate borne by the
Notes, to the extent lawful (such defaulted interest and interest thereon herein
collectively called "Defaulted Interest") shall forthwith cease to be payable to
the Holder on the Regular Record Date; and such Defaulted Interest may be paid
by the Company, at its election in each case, as provided in subsection (a) or
(b) below:

                  (a) The Company may elect to make payment of any Defaulted
Interest to the persons in whose names the Notes (or their respective
Predecessor Notes) are registered at the close of business on a Special Record
Date for the payment of such Defaulted Interest, which shall be fixed in the
following manner. The Company shall notify the Trustee in writing of the amount
of Defaulted Interest proposed to be paid on each Note and the date of the
proposed payment, and at the same time the Company shall deposit with the
Trustee an amount of money equal to the aggregate amount proposed to be paid in
respect of such Defaulted Interest or shall make arrangements satisfactory to
the Trustee for such deposit on or prior to the date of the proposed payment,
such money when deposited to be held in trust for the benefit of the persons
entitled to such Defaulted Interest as provided in this subsection (a).
Thereupon the Trustee shall fix a Special Record Date for the payment of such
Defaulted Interest which shall be not more than 15 days and not less than 10
days prior to the date of the proposed payment and not less than 10 days after
the receipt by the Trustee of the notice of the proposed payment. The Trustee
shall promptly notify the Company in writing of such Special Record Date. In the
name and at the expense of the Company, the Trustee shall cause notice of the
proposed payment of such Defaulted Interest and the Special Record Date therefor
to be mailed, first-class postage prepaid, to each Holder at its address as it
appears in the Note Register, not less than 10 days prior to such Special Record
Date. Notice of the proposed payment of such Defaulted Interest and the Special
Record Date therefor having been so mailed, such Defaulted Interest shall be
paid to the persons in whose names the Notes (or their respective Predecessor
Notes) are registered on such Special Record Date and shall no longer be payable
pursuant to the following subsection (b).

                  (b) The Company may make payment of any Defaulted Interest in
any other lawful manner not inconsistent with the requirements of any securities
exchange on which the Notes may be listed, and upon such notice as may be
required by such exchange, if, after written notice given by the Company to the
Trustee of the proposed payment pursuant to this subsection (b), such payment
shall be deemed practicable by the Trustee.

                  Subject to the foregoing provisions of this Section, each Note
delivered under this Indenture upon registration of transfer of or in exchange
for or in lieu of any other Note shall carry the rights to interest accrued and
unpaid, and to accrue, which were carried by such other Note.

                  Section 3.08. Persons Deemed Owners.

                  Prior to and at the time of due presentment for registration
of transfer, the Company, the Trustee and any agent of the Company or the
Trustee may treat the person in whose name any Note is registered in the Note
Register as the owner of such Note for the purpose of receiving payment of
principal of, premium, if any, and (subject to Section 3.07 hereof) interest on
such Note and for all other purposes whatsoever, whether or not such Note shall
be overdue, and neither the Company, the Trustee nor any agent of the Company or
the Trustee shall be affected by notice to the contrary.

                  Section 3.09. Cancellation.

                  All Notes surrendered for payment, redemption, registration of
transfer or exchange shall be delivered to the Trustee and, if not already
canceled, shall be promptly canceled by it. The Company may at any time deliver
to the Trustee for cancellation any Notes previously authenticated and delivered
hereunder which the Company may have acquired in any manner whatsoever, and all
Notes so delivered shall be promptly canceled by the Trustee. The Registrar and
the Paying Agent shall forward to the Trustee any Notes surrendered to them for
registration of transfer or exchange, redemption or payment. The Trustee and no
one else shall cancel all Notes surrendered for registration of transfer,
exchange, payment, replacement or cancellation. No Notes shall be authenticated
in lieu of or in exchange for any Notes canceled as provided in this Section
3.09 hereof, except as expressly permitted by this Indenture. All canceled Notes
held by the Trustee shall be destroyed and certification of their destruction
delivered to the Company unless by a Company Order the Company shall timely
direct that the canceled Notes be returned to it. The Trustee shall provide the
Company a list of all Notes that have been canceled from time to time as
requested by the Company.

                  Section 3.10. Computation of Interest.

                  Interest on the Notes shall be computed on the basis of a
360-day year of twelve 30-day months.

                  Section 3.11. Legal Holidays.

                  In any case where any Interest Payment Date, Redemption Date,
date established for the payment of Defaulted Interest or Stated Maturity of any
Note shall not be a Business Day, then (notwithstanding any other provision of
this Indenture or of the Notes) payment of principal, premium, if any, or
interest need not be made on such date, but may be made on the next succeeding
Business Day with the same force and effect as if made on the Interest Payment
Date, Redemption Date, date established for the payment of Defaulted Interest or
at the Stated Maturity, as the case may be. In such event, no interest shall
accrue with respect to such payment for the period from and after such Interest
Payment Date, Redemption Date, date established for the payment of Defaulted
Interest or Stated Maturity, as the case may be, to the next succeeding Business
Day and, with respect to any Interest Payment Date, interest for the period from
and after such Interest Payment Date shall accrue with respect to the next
succeeding Interest Payment Date.

                  Section 3.12. CUSIP and CINS Numbers.

                  The Company in issuing the Notes may use "CUSIP" and "CINS"
numbers (if then generally in use), and if so, the Trustee shall use the CUSIP
or CINS numbers, as the case may be, in notices of redemption or exchange as a
convenience to Holders; provided, however, that any such notice may state that
no representation is made as to the correctness or accuracy of the CUSIP or CINS
number, as the case may be, printed in the notice or on the Notes, and that
reliance may be placed only on the other identification numbers printed on the
Notes. The Company shall promptly notify the Trustee in writing of any change in
the CUSIP or CINS number of any type of Notes.

                  Section 3.13. Paying Agent To Hold Money in Trust.

                  Each Paying Agent shall hold in trust for the benefit of the
Noteholders or the Trustee all money held by the Paying Agent for the payment of
principal of, premium, if any, or interest on the Notes, and shall notify the
Trustee of any default by the Company in making any such payment. Money held in
trust by the Paying Agent need not be segregated except as required by law and
in no event shall the Paying Agent be liable for any interest on any money
received by it hereunder. The Company at any time may require the Paying Agent
to pay all money held by it to the Trustee and account for any funds disbursed
and the Trustee may at any time during the continuance of any Event of Default,
upon a Company Order to the Paying Agent, require such Paying Agent to pay
forthwith all money so held by it to the Trustee and to account for any funds
disbursed. Upon making such payment, the Paying Agent shall have no further
liability for the money delivered to the Trustee.

                  Section 3.14. Treasury Notes.

                  In determining whether the Holders of the required aggregate
principal amount of Notes have concurred in any direction, waiver, consent or
notice, Notes owned by the Company or an Affiliate of the Company shall be
considered as though they are not outstanding, except that for the purposes of
determining whether the Trustee shall be protected in relying on any such
direction, waiver or consent, only Notes which a Responsible Officer of the
Trustee actually knows are so owned shall be so considered. The Company shall
notify the Trustee, in writing, when it or any of its Affiliates repurchases or
otherwise acquires Notes, of the aggregate principal amount of such Notes so
repurchased or otherwise acquired.

                  Section 3.15. Deposits of Monies.

                  Prior to 1:00 p.m. New York City time on each Interest Payment
Date, maturity date, Change of Control Payment Date and Asset Sale Offer
Purchase Date, the Company shall have deposited with the Paying Agent in
immediately available funds money sufficient to make cash payments, if any, due
on such Interest Payment Date, maturity date, Change of Control Payment Date and
Asset Sale Offer Purchase Date, as the case may be, in a timely manner which
permits the Paying Agent to remit payment to the Holders on such Interest
Payment Date, maturity date, Change of Control Payment Date and Asset Sale Offer
Purchase Date, as the case may be.

                  Section 3.16. Book-Entry Provisions for Global Notes.

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

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

                  (b) Transfers of Global Notes shall be limited to transfers in
whole, but not in part, to the Depository, its successors or their respective
nominees. Interests of beneficial owners in the Global Notes may be transferred
or exchanged for Physical Notes in accordance with the rules and procedures of
the Depository and the provisions of Sections 3.03 and 3.17 hereof. In addition,
Physical Notes shall be transferred to all beneficial owners, in exchange for
their beneficial interests in Global Notes if (i) the Depository notifies the
Company that it is unwilling or unable to continue as Depository for any Global
Note, or that it will cease to be a "Clearing Agency" under the Exchange Act,
and in either case a successor Depository is not appointed by the Company within
90 days of such notice or (ii) an Event of Default has occurred and is
continuing and the Registrar has received a written request from the Depository
to issue Physical Notes.

                  (c) In connection with any transfer or exchange of a portion
of the beneficial interest in any Global Note to beneficial owners pursuant to
paragraph (b), the Registrar shall (if one or more Physical Notes are to be
issued) reflect on its books and records the date and a decrease in the
principal amount at maturity of the Global Note in an amount equal to the
principal amount at maturity of the beneficial interest in the Global Note to be
transferred, and the Company shall execute, and the Trustee shall authenticate
and deliver, one or more Physical Notes of like tenor and principal amount of
authorized denominations.

                  (d) In connection with the transfer of Global Notes as an
entirety to beneficial owners pursuant to paragraph (b), the Global Notes shall
be deemed to be surrendered to the Trustee for cancellation, and the Company
shall execute, and the Trustee shall authenticate and deliver, to each
beneficial owner identified by the Depository in exchange for its beneficial
interest in the Global Notes, an equal aggregate principal amount at maturity of
Physical Notes of like tenor of authorized denominations.

                  (e) Any Physical Note constituting a Restricted Note delivered
in exchange for an interest in a Global Note pursuant to subparagraph (b), (c)
or (d) of this Section 3.16 shall, except as otherwise provided by Section 3.17
hereof, bear the Private Placement Legend.

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

         Affiliate of the Company has held any beneficial interest in such Note,
         or portion thereof, at any time on or prior to the second anniversary
         of the Issue Date and such transfer can otherwise be lawfully made

         thereunder or (y) such transfer is being made by a proposed transferor
         who has checked the box provided for on the form of Note stating, or

         form of Note stating, or has otherwise advised the Company and the
         Registrar in writing, that it is purchasing the Note for its own

         investment discretion and that it and any such account is a QIB within
         the meaning of Rule 144A, and is aware that the sale to it is being

         date and an increase in the principal amount at maturity of the 144A
         Global Note in an amount equal to the principal amount at maturity of
         Physical Notes to be transferred, and the Trustee shall cancel the
         Physical Note so transferred; and

delivered to the Registrar an Opinion of Counsel reasonably satisfactory to the
Company and the Trustee to the effect that neither such legend nor the related
restrictions on transfer are required in order to maintain compliance with the
provisions of the Securities Act or (iii) such Note has been sold pursuant to an
effective registration statement under the Securities Act.

                  (e) Other Transfers. If a Holder proposes to transfer a Note
constituting a Restricted Note pursuant to any exemption from the registration
requirements of the Securities Act other than as provided for by Section 3.17(a)
and (b) hereof, the Registrar shall only register such transfer or exchange if
such transferor delivers an Opinion of Counsel satisfactory to the Company and
the Registrar that such transfer is in compliance with the Securities Act and
the terms of this Indenture; provided, however, that the Company may, based upon
the opinion of its counsel, instruct the Registrar by a Company Order not to
register such transfer in any case where the proposed transferee is not a QIB,
or a Non-U.S. person or Institutional Accredited Investor.

                  (f) General. By its acceptance of any Note bearing the Private
Placement Legend, each Holder of such a Note acknowledges the restrictions on
transfer of such Note set forth in this Indenture and in the Private Placement
Legend and agrees that it will transfer such Note only as provided in this
Indenture.

such letters, notices or other written communications at any reasonable time
upon the giving of reasonable prior written notice to the Registrar.

Indenture insofar as such Notes are concerned (and the Trustee, at the expense
of the Company, and, upon Company Request, shall execute proper instruments
acknowledging the same), except for the following, which shall survive until
otherwise terminated or discharged hereunder: (a) the rights of Holders of
Defeased Notes to receive, solely from the trust fund described in Section 4.04
hereof and as more fully set forth in such Section, payments in respect of the
principal of, premium, if any, and interest on such Notes when such payments are
due, (b) the Company's obligations with respect to such Defeased Notes under
Sections 3.04, 3.05, 3.06, 10.02 and 10.03 hereof, (c) the rights, powers,
trusts, duties and immunities of the Trustee hereunder, including, without
limitation, the Trustee's rights under Sections 4.05 and 6.07 hereof, and (d)
this Article Four. Subject to compliance with this Article Four, the Company may
exercise its option under this Section 4.02 notwithstanding the prior exercise
of its option under Section 4.03 hereof with respect to the Notes.

                  Section 4.03. Covenant Defeasance.

                  Upon the Company's exercise under Section 4.01 hereof of the
option applicable to this Section 4.03, the Company shall be released from its
obligations under any covenant or provision contained in Sections 10.06 through
10.23 hereof and the provisions of clause (c) of Section 8.01 shall not apply,
with respect to the Defeased Notes, on and after the date the conditions set
forth below are satisfied (hereinafter, "covenant defeasance"), and the Defeased
Notes shall thereafter be deemed not to be "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. For this
purpose, such covenant defeasance means that, with respect to the Defeased
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 Section or
Article, whether directly or indirectly, by reason of any reference elsewhere
herein to any such Section or Article or by reason of any reference in any such
Section or Article 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 5.01(iii) or (iv) hereof, but, except as specified above, the
remainder of this Indenture and such Defeased Notes shall be unaffected thereby.

                  Section 4.04. Conditions to Defeasance or Covenant Defeasance.

                  The following shall be the conditions to application of either
Section 4.02 or Section 4.03 hereof to the Defeased Notes:

                  (1)  The Company shall irrevocably have deposited or
         caused to be deposited with the Trustee (or another trustee satisfying
         the requirements of Section 6.09 hereof who shall agree to comply with
         the provisions of this Article Four applicable to it) as trust funds in
         trust for the purpose of making the following payments, specifically
         pledged as security for, and dedicated solely to, the benefit of the
         Holders of such Notes, (a) money in an amount, or (b) U.S. Government
         Obligations which through the scheduled payment of principal, premium,
         if any, and interest in respect thereof in accordance with their terms
         will provide, not later than the due date of any payment, money in an
         amount, or (c) a combination thereof, in any such case, sufficient
         without reinvestment, in the opinion of a nationally recognized firm of
         independent public accountants expressed in a written certification
         thereof delivered to the Trustee, to pay and discharge the entire
         Indebtedness in respect of, and which shall be applied by the Trustee
         (or other qualifying trustee) to pay and discharge, the principal of,
         premium, if any, and interest on the Defeased Notes at the Stated
         Maturity of such principal or installment of principal, premium, if
         any, or interest or (if the Company has made irrevocable arrangements
         satisfactory to such Trustee for the giving of notice of redemption by
         such Trustee in the name and at the expense of the Company) the
         redemption date thereof, as the case may be, in accordance with the
         terms of the Indenture and the Notes; provided, however, that the
         Trustee shall have been irrevocably instructed to apply such cash or
         the proceeds of such U.S. Government Obligations to said payments with
         respect to the Notes;

                  (2) No Default with respect to the Outstanding Notes
         shall have occurred and be continuing on the date of such deposit or,
         insofar as Section 4.02 hereof is concerned, at any time during the
         period ending on the ninety-first day after the date of such deposit
         (it being understood that this condition shall not be deemed satisfied
         until the expiration of such period) no Default relating to Section
         5.01(viii), (ix) or (x) hereof;

                  (3) Neither the Company nor any Subsidiary of the
         Company is an "insolvent person" within the meaning of any applicable
         Bankruptcy Law on the date of such deposit or at any time during the
         period ending on the ninety-first day after the date of such deposit
         (it being understood that this condition shall not be deemed satisfied
         until the expiration of such period);

                  (4) Such defeasance or covenant defeasance shall not
         cause the Trustee for the Notes to have a conflicting interest in
         violation of Section 6.08 hereof and for purposes of the Trust
         Indenture Act with respect to any securities of the Company;

                  (5) Such defeasance or covenant defeasance shall not
         result in a breach or violation of, or constitute a default under, this
         Indenture or any other material agreement or instrument to which the
         Company is a party or by which it is bound;

                  (6) In the case of an election under Section 4.02
         hereof, the Company shall have delivered to the Trustee an Opinion of
         Counsel stating that (x) the Company has received from, or there has
         been published by, the Internal Revenue Service a ruling or (y) since
         the date hereof, there has been a change in the applicable federal
         income tax law, in either case to the effect that, and based thereon
         such opinion shall confirm that, the Holders of the Outstanding Notes
         will not recognize income, gain or loss for federal income tax purposes
         as a result of such deposit, defeasance and discharge to be effected
         with respect to the Notes and will be subject to federal income tax on
         the same amount, in the same manner and at the same times as would have
         been the case if such deposit, defeasance and discharge had not
         occurred;

                  (7) In the case of an election under Section 4.03
         hereof, the Company shall have delivered to the Trustee an Opinion of
         Counsel to the effect that the Holders of the Outstanding Notes will
         not recognize income, gain or loss for federal income tax purposes as a
         result of the deposit and covenant defeasance to be effected with
         respect to the Notes and will be subject to Federal income tax on the
         same amount, in the same manner and at the same times as would have
         been the case if such deposit and covenant defeasance had not occurred;

                  (8) The Company shall have delivered to the Trustee, an
         Opinion of Counsel to the effect that, immediately following the
         ninety-first day after the deposit, the trust funds established
         pursuant to this Article will not be subject to the effect of any
         applicable bankruptcy, insolvency, reorganization or similar laws
         affecting creditors' rights generally under any applicable U.S. Federal
         or state law;

                  (9) The Company shall have delivered to the Trustee an
         Officers' Certificate stating that the deposit made by the Company
         pursuant to its election under Section 4.02 or 4.03 hereof was not made
         by the Company with the intent of preferring the Holders over the other
         creditors of the Company or with the intent of defeating, hindering,
         delaying or defrauding creditors of the Company or others;

                  (10) The Company shall have delivered to the Trustee an
         Officers' Certificate and an Opinion of Counsel, each stating that (i)
         all conditions precedent (other than conditions requiring the passage
         of time) provided for relating to either the defeasance under Section
         4.02 or the covenant defeasance under Section 4.03 (as the case may be)
         have been complied with as contemplated by this Section 4.04 and (ii)
         if any other Indebtedness of the Company shall then be outstanding or
         committed, such defeasance or covenant defeasance will not violate the
         provisions of the agreements or instruments evidencing such
         Indebtedness; and

                  (11) Such defeasance or covenant defeasance shall not
         result in a trust arising from such deposit constituting an investment
         company within the meaning of the Investment Company Act of 1940, as
         amended, unless such trust shall be registered under the Act or exempt
         from registration thereunder.

                  Opinions required to be delivered under this Section may have
such qualifications as are customary for opinions of the type required and
reasonably acceptable to the Trustee.

                  Section 4.05. Deposited Money and U.S. Government Obligations
                                To Be Held in Trust; Other Miscellaneous
                                Provisions.

                  Subject to the proviso of the last paragraph of Section 10.03,
all money and U.S. Government Obligations (including the proceeds thereof)
deposited with the Trustee (or other qualifying trustee, collectively for
purposes of this Section 4.05, the "Trustee") pursuant to Section 4.04 in
respect of the Defeased Notes shall be held in trust and applied by the Trustee,
in accordance with the provisions of such Notes and this Indenture, to the
payment, either directly or through any Paying Agent (other than the Company) as
the Trustee may determine, to the Holders of such Notes of all sums due and to
become due thereon in respect of principal, premium, if any, and interest, but
such money need not be segregated from other funds except to the extent required
by law.

                  The Company shall pay and indemnify the Trustee, its officers,
directors and agents and hold such harmless against any tax, fee or other charge
imposed on or assessed against the U.S. Government Obligations deposited
pursuant to Section 4.04 or the principal, premium, if any, 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 Defeased Notes.

                  Anything in this Article Four to the contrary notwithstanding,
the Trustee shall deliver or pay to the Company from time to time upon Company
Request any money or U.S. Government Obligations held by it as provided in
Section 4.04 which, in the opinion of an internationally recognized firm of
independent public accountants expressed in a written certification thereof
delivered to the Trustee, are in excess of the amount thereof which would then
be required to be deposited to effect an equivalent defeasance or covenant
defeasance.

                  Section 4.06. Reinstatement.

                  If the Trustee or Paying Agent is unable to apply any money or
U.S. Government Obligations in accordance with Section 4.02 or 4.03 hereof, as
the case may be, by reason of any order or judgment of any court or governmental
authority enjoining, restraining or otherwise prohibiting such application, then
the obligations of the Company under this Indenture and the Notes shall be
revived and reinstated as though no deposit had occurred pursuant to Section
4.02 or 4.03 hereof, as the case may be, until such time as the Trustee or
Paying Agent is permitted to apply all such money and U.S. Government
Obligations in accordance with Section 4.02 or 4.03 hereof, as the case may be;
provided, however, that if the Company makes any payment of principal, premium,
if any, or interest on any Note following the reinstatement of its obligations,
the Company shall be subrogated to the rights of the Holders of such Notes to
receive such payment from the money and U.S. Government Obligations held by the
Trustee or Paying Agent.

         that remains in effect; or

                  Section 5.02. Acceleration of Maturity Rescission and
                                Annulment.

                  If an Event of Default (other than an Event of Default
specified in clause (viii), (ix) or (x) of Section 5.01 hereof with respect to
the Company) occurs and is continuing, then the Trustee or the holders of at
least 25% in Accreted Value of the Outstanding Notes may, by written notice, and
the Trustee upon the request of the holders of not less than 25% in Accreted
Value of the Outstanding Notes shall, declare the Default Amount of all
Outstanding Notes to be immediately due and payable and upon any such
declaration such amounts shall become immediately due and payable. If an Event
of Default specified in clause (viii), (ix) or (x) above with respect to the
Company occurs and is continuing, then the Default Amount of all Outstanding
Notes shall ipso facto become and be immediately due and payable without any
declaration or other act on the part of the Trustee or any Holder.

                  After a declaration of acceleration or any ipso facto
acceleration as related to clause (viii), (ix) or (ix) of Section 5.01, the
holders of a majority in Accreted Value of the Outstanding Notes may, by notice
to the Trustee, rescind such declaration of acceleration and its consequences if
all existing Events of Default, other than nonpayment of the principal of and
accrued and unpaid interest on, the Notes that has become due solely as a result
of such acceleration, have been cured or waived and if the rescission of
acceleration would not conflict with any judgment or decree.

                  Section 5.03. Collection of Indebtedness and Suits for
                                Enforcement by Trustee.

                  The Company covenants that if an Event of Default specified in
Section 5.01(i), 5.01(ii) or 5.01(iii) (to the extent relating to a payment
required by Section 10.10 or Section 10.15) shall have occurred and be
continuing, the Company will, upon demand of the Trustee, pay to the Trustee,
for the benefit of the Holders of such Notes, the whole amount then due and
payable on such Notes for principal, premium, if any, and interest, with
interest upon the overdue principal, premium, if any, and, to the extent that
payment of such interest shall be legally enforceable, upon overdue installments
of interest, at the rate then borne by the Notes; and, in addition thereto, 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.

                  If the Company fails to pay such amounts forthwith upon such
demand, the Trustee, in its own name and as trustee of an express trust, may,
but is not obligated under this paragraph to, institute a judicial proceeding
for the collection of the sums so due and unpaid and may, but is not obligated
under this paragraph to, prosecute such proceeding to judgment or final decree,
and may, but is not obligated under this paragraph to, enforce the same against
the Company or any other obligor upon the Notes and collect the moneys adjudged
or decreed to be payable in the manner provided by law out of the property of
the Company or any other obligor upon the Notes, wherever situated.

                  If an Event of Default occurs and is continuing, the Trustee
may in its discretion, but is not obligated under this paragraph to, (i) proceed
to protect and enforce its rights and the rights of the Holders under this
Indenture by such appropriate private or judicial proceedings as the Trustee
shall deem most effectual to protect and enforce such rights, whether for the
specific enforcement of any covenant or agreement contained in this Indenture or
in aid of the exercise of any power granted herein or (ii) proceed to protect
and enforce any other proper remedy. No recovery of any such judgment upon any
property of the Company shall affect or impair any rights, powers or remedies of
the Trustee or the Holders.

                  Section 5.04. Trustee May File Proofs of Claims.

                  In case of the pendency of any receivership, insolvency,
liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or
other judicial proceeding relative to the Company or any other obligor upon the
Notes or the property of the Company or of such other obligor or their
creditors, the Trustee (irrespective of whether the principal of the Notes shall
then be due and payable as therein expressed or by declaration or otherwise and
irrespective of whether the Trustee shall have made any demand on the Company
for the payment of overdue principal or interest) shall be entitled and
empowered, by intervention in such proceeding or otherwise,

                  (a) to file and prove a claim for the whole amount of
principal, premium, if any, and interest owing and unpaid in respect of the
Notes and to file such 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, fees, expenses, disbursements and advances of the
Trustee, its agents and counsel) and of the Holders allowed in such judicial
proceeding, and

                  (b) to collect and receive any moneys or other property
payable or deliverable on any such claims and to distribute the same;

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 the
Trustee as administrative expenses associated with any such proceeding, and in
the event that the Trustee shall consent to the making of such payments directly
to Holders, any amount due 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 6.07 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 6.07 hereof out of the estate in
any such proceeding, shall be denied for any reason, payment of the same shall
be secured by a Lien on, and shall be paid out of, any and all distributions,
dividends, money, securities and other properties that the Holders may be
entitled to receive in such proceeding whether in liquidation or under any plan
of reorganization or arrangement or otherwise.

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

                  Section 5.05. Trustee May Enforce Claims Without Possession of
Notes.

                  All rights of action and claims under this Indenture, or the
Notes may be prosecuted and enforced by the Trustee without the possession of
any of the Notes or the production thereof in any proceeding relating thereto,
and any such proceeding instituted by the Trustee shall be brought in its own
name and as trustee of an express trust, and any recovery of judgment shall,
after provision for the payment of the reasonable compensation, fees, expenses,
disbursements and advances of the Trustee, its agents and counsel, be for the
ratable benefit of the Holders of the Notes in respect of which such judgment
has been recovered.

                  Section 5.06. Application of Money Collected.

                  Any money collected by the Trustee pursuant to this Article
shall be applied in the following order, at the date or dates fixed by the
Trustee and, in case of the distribution of such money on account of principal,
premium, if any, or interest, upon presentation of the Notes and the notation
thereon of the payment if only partially paid and upon surrender thereof if
fully paid:

                  First:  to the Trustee for amounts due under Section 6.07;

                  Second: to Holders for interest accrued on the Notes, ratably,
         without preference or priority of any kind, according to the amounts
         due and payable on the Notes for interest;

                  Third: to Holders of principal and premium, if any, owing
         under the Notes, ratably, without preference or priority of any kind,
         according to the amounts due and payable on the Notes for principal;
         and

                  Fourth:  the balance, if any, to the Company.

                  The Trustee, upon prior written notice to the Company, may fix

Section 5.06.

                  Section 5.07. Limitation on Suits.

                  No Holder of any Notes shall have any right to institute any
proceeding, judicial or otherwise, with respect to this Indenture, or for the
appointment of a receiver or trustee, or for any other remedy hereunder, unless

                  (a) such Holder has previously given written notice to the
         Trustee of a continuing Event of Default;

                  (b) the Holders of not less than 25% in Accreted Value of the
         Outstanding Notes shall have made written request to the Trustee to
         institute proceedings in respect of such Event of Default in its own
         name as Trustee hereunder;

                  (c) such Holder or Holders have offered to the Trustee
         indemnity satisfactory to it against the costs, expenses and
         liabilities to be incurred in compliance with such request;

                  (d) the Trustee for 60 days after its receipt of such notice,
         request and offer of indemnity has failed to institute any such
         proceeding; and

                  (e) no direction inconsistent with such written request has
         been given to the Trustee during such 60-day period by the Holders of a
         majority in aggregate principal amount of the Outstanding Notes;

it being understood and intended that no one or more Holders shall have any
right in any manner whatever by virtue of, or by availing of, any provision of
this Indenture or any Note to affect, disturb or prejudice the rights of any
other Holders, or to obtain or to seek to obtain priority or preference over any
other Holders or to enforce any right under this Indenture or any Note, except
in the manner provided in this Indenture and for the equal and ratable benefit
of all the Holders.

                  Section 5.08. Unconditional Right of Holders To Re-
                                ceive Principal, Premium and Interest.

                  Notwithstanding any other provision in this Indenture, the
Holder of any Note shall have the right, which is absolute and unconditional, to
receive cash payment of the principal of, premium, if any, and (subject to
Section 3.07 hereof) interest on such Note on the respective Stated Maturities
expressed in such Note (or, in the case of redemption, on the respective
Redemption Date) and to institute suit for the enforcement of any such payment,
and such rights shall not be impaired without the consent of such Holder.

                  Section 5.09. Restoration of Rights and Remedies.

                  If the Trustee or any Holder has instituted any proceeding to
enforce any right or remedy under this Indenture or any Note and such proceeding
has been discontinued or abandoned for any reason, or has been determined
adversely to the Trustee or to such Holder, then and in every such case the
Company, the Trustee and the Holders shall, subject to any determination in such
proceeding, be restored severally and respectively to their former positions
hereunder, and thereafter all rights and remedies of the Trustee and the Holders
shall continue as though no such proceeding had been instituted.

                  Section 5.10. Rights and Remedies Cumulative.

                  Except as provided in Section 3.06, no right or remedy herein
conferred upon or reserved to the Trustee or to the Holders is intended to be
exclusive of any other right or remedy, and every right and remedy shall, to the
extent permitted by law, be cumulative and in addition to every other right and
remedy given hereunder or now or hereafter existing at law or in equity or
otherwise. The assertion or employment of any right or remedy hereunder, or
otherwise, shall not prevent the concurrent assertion or employment of any other
appropriate right or remedy.

                  Section 5.11. Delay or Omission Not Waiver.

                  No delay or omission of the Trustee or of any Holder of any
Note to exercise any right or remedy accruing upon any Event of Default shall
impair any such right or remedy or constitute a waiver of any such Event of
Default or an acquiescence therein. Every right and remedy given by this Article
Five or by law to the Trustee or to the Holders may be exercised from time to
time, and as often as may be deemed expedient, by the Trustee or by the Holders,
as the case may be.

                  Section 5.12. Control by Majority.

                  The Holders of a majority in Accreted Value of the Outstanding
Notes shall have the right to direct the time, method and place of conducting
any proceeding for any remedy available to the Trustee, or exercising any trust
or power conferred on the Trustee, provided, however, that:

                  (a) such direction shall not be in conflict with any rule of
law or with this Indenture or any Note or expose the Trustee to personal
liability; and

                  (b) the Trustee may take any other action deemed proper by the
Trustee which is not inconsistent with such direction.

                  Section 5.13. Waiver of Past Defaults.

                  The Holders of not less than a majority in Accreted Value of
the Outstanding Notes may on behalf of the Holders of all the Notes waive any
past Default hereunder and its consequences, except a Default

                  (a) in the payment of the principal of, or interest on any
Outstanding Note or

                  (b) in respect of a covenant or provision hereof which under
Article Nine cannot be modified or amended without the consent of the Holder of
each Outstanding Note affected thereby.

                  Upon any such waiver, such Default shall cease to exist, and
any Event of Default arising therefrom shall be deemed to have been cured, for
every purpose of this Indenture; but no such waiver shall extend to any
subsequent or other Default or Event of Default or impair any right consequent
thereon.

                  Section 5.14. Undertaking for Costs.

                  All parties to this Indenture agree, and each Holder of any
Note by his acceptance thereof shall be deemed to have agreed, that any court
may in its discretion require, 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, suffered or omitted by it as Trustee, the filing by any party litigant in
such suit of an undertaking to pay the costs of such suit, and that such court
may in its discretion assess reasonable costs, including reasonable attorneys'
fees, against any party litigant in such suit, having due regard to the merits
and good faith of the claims or defenses made by such party litigant; but the
provisions of this Section 5.14 shall not apply to any suit instituted by the
Trustee, to any suit instituted by any Holder, or group of Holders, holding in
the aggregate more than 10% in Accreted Value of the Outstanding Notes, or to
any suit instituted by any Holder for the enforcement of the payment of the
principal of, premium, if any, or interest on any Note on or after the
respective Stated Maturities expressed in such Note (or, in the case of
redemption, on or after the respective Redemption Dates).

                  Section 5.15. Waiver of Stay, Extension or Usury Laws.

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

                  Section 5.16. Unconditional Right of Holders To
                                Receive Payment.

                  Notwithstanding any other provision in this Indenture and any
other provision of any Note, the right of any Holder of any Note to receive
payment of the principal of, premium, if any, and interest on such Note on or
after the respective Stated Maturities (or the respective Redemption Dates, in
the case of redemption) expressed in such Note, or after such respective dates,
shall not be impaired or affected without the consent of such Holder.

                                   ARTICLE SIX

                                   THE TRUSTEE

                  Section 6.01. Certain Duties and Responsibilities.

                  (a)  Except during the continuance of an Event of Default,

                  (1) the Trustee undertakes to perform such duties and
         only such duties as are specifically set forth in this Indenture, and
         no implied covenants or obligations shall be read into this Indenture
         against the Trustee; and

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

                  (b) During the existence of an Event of Default, the Trustee
is required to exercise such rights and powers vested in it under this Indenture
use the same degree of care and skill in its exercise thereof as a prudent
person would exercise under the circumstances in the conduct of such person's
own affairs.

                  (c) No provision of this Indenture shall be construed to
relieve the Trustee from liability for its own negligent action, its own
negligent failure to act, or its own willful misconduct, except that no
provision of this Indenture shall require the Trustee to expend or risk its own
funds or otherwise incur any financial liability in the performance of any of
its duties hereunder, or in the exercise of any of its rights or powers, if it
shall have reasonable grounds for believing that repayment of such funds or
adequate indemnity against such risk or liability is not reasonably assured to
it.

                  (d) Whether or not therein expressly so provided, every
provision of this Indenture relating to the conduct or affecting the liability
of or affording protection to the Trustee shall be subject to the provisions of
this Section 6.01.

                  Section 6.02. Notice of Defaults.

                  Within 45 days after the occurrence of any Default, the
Trustee shall transmit by mail to all Holders, as their names and addresses
appear in the Note Register, notice of such Default hereunder actually known to
a Responsible Officer, the Trustee, unless such Default shall have been cured or
waived; provided, however, that, except in the case of a Default in the payment
of the principal of, premium, if any, or interest on any Note or in the case of
any Default arising from the occurrence of a Change of Control, the Trustee
shall be protected in withholding such notice if and so long as a trust
committee of Responsible Officers of the Trustee in good faith determines that
the withholding of such notice is in the interest of the Holders.

                  Section 6.03. Certain Rights of Trustee.

                  Subject to Section 6.01 hereof and the provisions of Section
315 of the Trust Indenture Act:

                  (a) the Trustee may conclusively rely and shall be fully
protected in acting or refraining from acting upon any resolution, certificate,
statement, instrument, opinion, report, notice, request, direction, consent,
order, bond, debenture, note, other evidence of indebtedness or other paper or
document believed by it to be genuine and to have been signed or presented by
the proper party or parties;

                  (b) any request or direction of the Company mentioned herein
shall be sufficiently evidenced by a Company Request or Company Order and any
resolution of the Board may be sufficiently evidenced by a Board Resolution
thereof;

                  (c) the Trustee may consult with counsel and any advice of
such counsel or any Opinion of Counsel shall be full and complete authorization
and protection in respect of any action taken, suffered or omitted by it
hereunder in good faith and in reliance thereon in accordance with such advice
or Opinion of Counsel;

                  (d) 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 pursuant to this Indenture, unless such Holders
shall have offered to the Trustee reasonable security or indemnity satisfactory
to it against the costs, expenses and liabilities which might be incurred by the
Trustee in compliance with such request or direction;

                  (e) the Trustee shall not be liable for any action taken or
omitted by it in good faith and believed by it to be authorized or within the
discretion, rights or powers conferred upon it by this Indenture other than any
liabilities arising out of its own negligence;

                  (f) the Trustee shall not be bound to make any investigation
into the facts or matters stated in any resolution, certificate, statement,
instrument, opinion, report, notice, request, direction, consent, order,
approval, appraisal, bond, debenture, note, coupon, security, other evidence of
indebtedness or other paper or document unless requested in writing so to do by
the Holders of not less than a majority in aggregate principal amount of the
Notes then Outstanding; provided, however, that, if the payment within a
reasonable time to the Trustee of the costs, expenses or liabilities likely to
be incurred by it in the making of such investigation is, in the opinion of the
Trustee, not reasonably assured to the Trustee by the security afforded to it by
the terms of this Indenture, the Trustee may require indemnity satisfactory to
it against such expenses or liabilities as a condition to proceeding; the
reasonable expenses of every such investigation shall be paid by the Company or,
if paid by the Trustee or any predecessor Trustee, shall be repaid by the
Company upon demand; provided, further, the Trustee in its discretion may make
such further inquiry or investigation into such facts or matters as it may deem
fit, and, if the Trustee shall determine to make such further inquiry or
investigation, it shall be entitled to examine the books, records and premises
of the Company, personally or by agent or attorney;

                  (g) the Trustee may execute any of the trusts or powers
hereunder or perform any duties hereunder either directly or by or through
agents, attorneys, custodian or nominees and the Trustee shall not be
responsible for any misconduct or negligence on the part of any agent, attorney,
custodian or nominee appointed with due care by it hereunder;

                  (h) except with respect to Section 10.01, the Trustee
shall have no duty to inquire as to the performance of the Company's covenants
in Article Ten. In addition, the Trustee shall not be deemed to have knowledge
of any Default or Event of Default except (i) any Event of Default occurring
pursuant to Sections 5.01(i), 5.01(ii) and 10.01 or (ii) any Default or Event of
Default of which the Trustee shall have received written notification or a
Responsible Officer obtained actual knowledge; and

                  (i) if the Trustee is acting in the capacity of Registrar
and/or Paying Agent, then the rights afforded to the Trustee under this Section
6.03 shall also be afforded to such Registrar and/or Paying Agent.

                  Section 6.04. Trustee Not Responsible for Recitals,
                                Dispositions of Notes or Application of
                                Proceeds Thereof.

                  The recitals contained herein and in the Notes, except the
Trustee's certificate of authentication, shall be taken as the statements of the
Company, and the Trustee assumes no responsibility for their correctness. The
Trustee makes no representations as to the validity or sufficiency of this
Indenture or of the Notes except that the Trustee represents that it is duly
authorized to execute and deliver this Indenture, authenticate the Notes and
perform its obligations hereunder and that the statements made by it in a
Statement of Eligibility and Qualification on Form T-1, if any, to be supplied
to the Company are true and accurate subject to the qualifications set forth
therein. The Trustee shall not be accountable for the use or application by the
Company of Notes or the proceeds thereof.

                  Section 6.05. Trustee and Agents May Hold
                                Notes; Collections; Etc.

                  The Trustee, any Paying Agent, Registrar or any other agent of
the Company, in its individual or any other capacity, may become the owner or
pledgee of Notes, with the same rights it would have if it were not the Trustee,
Paying Agent, Registrar or such other agent and, subject to Section 6.08 hereof
and Sections 310 and 311 of the Trust Indenture Act, may otherwise deal with the
Company and receive, collect, hold and retain collections from the Company with
the same rights it would have if it were not the Trustee, Paying Agent,
Registrar or such other agent.

                  Section 6.06. Money Held in Trust.

                  All moneys received by the Trustee shall, until used or
applied as herein provided, be held in trust for the purposes for which they
were received, but need not be segregated from other funds except to the extent
required herein or by law. The Trustee shall not be under any liability for
interest on any moneys received by it hereunder.

                  Section 6.07. Compensation and Indemnification of Trustee and
                                Its Prior Claim.

                  The Company covenants and agrees: (a) to pay to the Trustee
from time to time, and the Trustee shall be entitled to, reasonable compensation
for all services rendered by it hereunder (which shall not be limited by any
provision of law in regard to the compensation of a trustee of an express
trust); (b) to reimburse the Trustee and each predecessor Trustee upon its
request for all reasonable expenses, fees, disbursements and advances incurred
or made by or on behalf of it in accordance with any of the provisions of this
Indenture (including the reasonable compensation, fees, and the expenses and
disbursements of its counsel and of all agents and other persons not regularly
in its employ), except any such expense, disbursement or advance as may arise
from its negligence or bad faith; and (c) to indemnify the Trustee and any of
its officers, directors, employees and agents and each predecessor Trustee for,
and to hold it harmless against any loss, liability or expense (including
attorneys' fees and expenses incurred in defending themselves) incurred without
negligence or bad faith on its part, arising out of or in connection with the
acceptance or administration of this Indenture or the trusts hereunder and its
duties hereunder, including enforcement of this Section 6.07.

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

                  The obligations of the Company under this Section to
compensate and indemnify the Trustee and each predecessor Trustee and to pay or
reimburse the Trustee and each predecessor Trustee for expenses, disbursements
and advances shall constitute an additional obligation hereunder and shall
survive the satisfaction and discharge of this Indenture or the rejection or
termination of this Indenture under bankruptcy law. Such additional indebtedness
shall be a senior claim to that of the Notes upon all property and funds held or
collected by the Trustee as such, except funds held in trust for the benefit of
the Holders of particular Notes, and the Notes are hereby subordinated to such
senior claim. If the Trustee renders services and incurs expenses following an
Event of Default under Section 5.01(viii), Section 5.01(ix) or Section 5.01(x)
hereof, the parties hereto and the Holders by their acceptance of the Notes
hereby agree that such expenses are intended to constitute expenses of
administration under any bankruptcy law.

                  Section 6.08. Conflicting Interests.

                  The Trustee shall be subject to and comply with the provisions
of Section 310(b) of the Trust Indenture Act.

                  Section 6.09. Corporate Trustee Required; Eligibility.

                  There shall at all times be a Trustee hereunder which shall be
eligible to act as Trustee under Trust Indenture Act Sections 310(a)(1) and (2)
and which shall have a combined capital and surplus of at least $50,000,000. If
such corporation publishes reports of condition at least annually, pursuant to
law or to the requirements of any Federal, state, territorial or District of
Columbia supervising or examining authority, then for the purposes of this
Section, 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. If at any time the Trustee shall cease to be eligible in
accordance with the provisions of this Section, the Trustee shall resign
immediately in the manner and with the effect hereinafter specified in this
Article.

                  Section 6.10. Resignation and Removal; Appointment of
                                Successor Trustee.

                  (a) No resignation or removal of the Trustee and no
appointment of a successor Trustee pursuant to this Article shall become
effective until the acceptance of appointment by the successor Trustee under
Section 6.11.

                  (b) The Trustee, or any trustee or trustees hereinafter
appointed, may at any time resign by giving written notice thereof to the
Company at least 20 Business Days prior to the date of such proposed
resignation. Upon receiving such notice of resignation, the Company shall, after
all monies due and owing have been paid to the Trustee, promptly appoint a
successor trustee by written instrument executed by authority of the Board, a
copy of which shall be delivered to the resigning Trustee and a copy to the
successor Trustee. If an instrument of acceptance by a successor Trustee shall
not have been delivered to the Trustee within 20 Business Days after the giving
of such notice of resignation, the resigning Trustee may, or any Holder who has
been a bona fide Holder of a Note for at least six months may, on behalf of
himself and all others similarly situated, petition any court of competent
jurisdiction for the appointment of a successor Trustee. Such court may
thereupon, after such notice, if any, as it may deem proper, appoint a successor
Trustee.

                  (c) The Trustee may be removed at any time by an Act of the
Holders of a majority in principal amount of the Outstanding Notes, delivered to
the Trustee and to the Company.

                  (d) If at any time:

                  (1) the Trustee shall fail to comply with the
         provisions of Section 310(b) of the Trust Indenture Act in accordance
         with Section 6.08 hereof after written request therefor by the Company
         or by any Holder who has been a bona fide Holder of a Note for at least
         six months, or

                  (2) the Trustee shall cease to be eligible under
         Section 6.09 hereof and shall fail to resign after written request
         therefor by the Company or by any Holder who has been a bona fide
         Holder of a Note for at least six months, or

                  (3) the Trustee shall become incapable of acting or
         shall be adjudged a bankrupt or insolvent, or a receiver of the Trustee
         or of its property shall be appointed or any public officer shall take
         charge or control of the Trustee or of its property or affairs for the
         purpose or rehabilitation, conservation or liquidation,

then, in any case, (i) the Company by a Board Resolution may remove the Trustee,
or (ii) subject to Section 5.14, the Holder of any Note who has been a bona fide
Holder of a Note for at least six months may, on behalf of himself and all
others similarly situated, petition any court of competent jurisdiction for the
removal of the Trustee and the appointment of a successor Trustee. Such court
may thereupon, after such notice, if any, as it may deem proper and prescribe,
remove the Trustee and appoint a successor Trustee.

                  (e) If the Trustee shall resign, be removed or become
incapable of acting, or if a vacancy shall occur in the office of Trustee for
any cause, the Company, by a Board Resolution, shall promptly appoint a
successor Trustee. If, within one year after such resignation, removal or
incapability, or the occurrence of such vacancy, a successor Trustee shall be
appointed by Act of the Holders of a majority in principal amount of the
Outstanding Notes delivered to the Company and the retiring Trustee, the
successor Trustee so appointed shall, forthwith upon its acceptance of such
appointment, become the successor Trustee and supersede the successor Trustee
appointed by the Company. If no successor Trustee shall have been so appointed
by the Company or the Holders of the Notes and accepted appointment in the
manner hereinafter provided, the Holder of any Note who has been a bona fide
Holder for at least six months may, subject to Section 5.14, on behalf of
himself and all others similarly situated, petition any court of competent
jurisdiction for the appointment of a successor Trustee.

                  (f) The Company shall give notice of each resignation and each
removal of the Trustee and each appointment of a successor Trustee by mailing
written notice of such event by first-class mail, postage prepaid, to the
Holders of Notes as their names and addresses appear in the Note Register. Each
notice shall include the name of the successor Trustee and the address of its
Corporate Trust Office.

                  Section 6.11. Acceptance of Appointment by Successor.

                  Every successor Trustee appointed hereunder shall execute,
acknowledge and deliver to the Company and to the retiring Trustee an instrument
accepting such appointment, and thereupon the resignation or removal of the
retiring Trustee shall become effective and such successor Trustee, without any
further act, deed or conveyance, shall become vested with all the rights,
powers, trusts and duties of the retiring Trustee as if originally named as
Trustee hereunder; but, nevertheless, on the written request of the Company or
the successor Trustee, upon payment of amounts due to it pursuant to Section
6.07, such retiring Trustee shall duly assign, transfer and deliver to the
successor Trustee all moneys and property at the time held by it hereunder and
shall execute and deliver an instrument transferring to such successor Trustee
all the rights, powers, duties and obligations of the retiring Trustee. Upon
request of any such successor Trustee, the Company shall execute any and all
instruments for more fully and certainly vesting in and confirming to such
successor Trustee all such rights and powers. Any Trustee ceasing to act shall,
nevertheless, retain a prior claim upon all property or funds held or collected
by such Trustee to secure any amounts then due it pursuant to the provisions of
Section 6.07.

                  No successor Trustee with respect to the Notes shall accept
appointment as provided in this Section 6.11 unless at the time of such
acceptance such successor Trustee shall be eligible to act as Trustee under this
Article.

                  Upon acceptance of appointment by any successor Trustee as
provided in this Section 6.11, the successor shall give notice thereof to the
Holders of the Notes, by mailing such notice to such Holders at their addresses
as they shall appear on the Note Register. If the acceptance of appointment is
substantially contemporaneous with the resignation, then the notice called for
by the preceding sentence may be combined with the notice called for by Section
6.10. If the Company fails to give such notice within 10 days after acceptance
of appointment by the successor Trustee, the successor Trustee shall cause such
notice to be given at the expense of the Company.

                  Section 6.12. Merger, Conversion, Amalgamation, Consolidation
                                or Succession to Business.

                  Any corporation into which the Trustee may be merged or
converted or with which it may be consolidated or amalgamated, or any
corporation resulting from any merger, conversion, amalgamation or consolidation
to which the Trustee shall be a party, or any corporation succeeding to all or
substantially all of the corporate trust business of the Trustee, shall be the
successor of the Trustee hereunder without the execution or filing of any paper
or any further act on the part of any of the parties hereto, provided such
corporation shall be eligible under this Article Six to serve as Trustee
hereunder.

                  In case at the time such successor to the Trustee under this
Section 6.12 shall succeed to the trusts created by this Indenture any of the
Notes shall have been authenticated but not delivered, any such successor to the
Trustee may adopt the certificate of authentication of any predecessor Trustee
and deliver such Notes so authenticated; and, in case at that time any of the
Notes shall not have been authenticated, any successor to the Trustee under this
Section 6.12 may authenticate such Notes either in the name of any predecessor
hereunder or in the name of the successor Trustee; and in all such cases such
certificate shall have the full force which it is anywhere in the Notes or in
this Indenture provided that the certificate of the Trustee shall have been
authenticated.

this Section 7.04 for purposes of determining compliance with any provisions of
this Indenture.

                   CONSOLIDATION, MERGER, SALE OF ASSETS, ETC.

                  Section 8.01. Company May Consolidate, etc., Only on Certain
                                Terms.

                  The Company will not (i) consolidate or combine with or merge
with or into or, directly or indirectly, sell, assign, convey, lease, transfer
or otherwise dispose of all or substantially all of its properties and assets to
any person or persons in a single transaction or through a series of
transactions, or (ii) permit any of the Restricted Subsidiaries to enter into
any such transaction or series of transactions if it would result in the
disposition of all or substantially all of the properties or assets of the
Company and the Restricted Subsidiaries on a consolidated basis, unless, in the
case of either (i) or (ii), (a) the Company shall be the continuing person or,
if the Company is not the continuing person, the resulting, surviving or
transferee person (the "surviving entity") shall be a company organized and
existing under the laws of the United States or any State or territory thereof;
(b) the surviving entity shall expressly assume all of the obligations of the
Company under the Notes and this Indenture, and shall, if required by law to
effectuate such assumption, execute a supplemental indenture to effect such
assumption which supplemental indenture shall be delivered to the Trustee and
shall be in form and substance reasonably satisfactory to the Trustee; (c)
immediately after giving effect to such transaction or series of transactions on
a pro forma basis (including, without limitation, any Indebtedness incurred or
anticipated to be incurred in connection with or in respect of such transaction
or series of transactions), the Company or the surviving entity (assuming such
surviving entity's assumption of the Company's obligations under the Notes and
this Indenture), as the case may be, would be able to incur $1.00 of
Indebtedness under clause (A)(X) of the proviso of Section 10.11; (d)
immediately after giving effect to such transaction or series of transactions on
a pro forma basis (including, without limitation, any Indebtedness incurred or

or series of transactions), no Default shall have occurred and be continuing;
and (e) the Company or the surviving entity, as the case may be, shall have
delivered to the Trustee an Officers' Certificate and Opinion of Counsel stating
that such transaction or series of transactions, and, if a supplemental
indenture is required in connection with such transaction or series of
transactions to effectuate such assumption, such supplemental indenture,
complies with this covenant and that all conditions precedent in this Indenture
relating to the transaction or series of transactions have been satisfied.

                  Section 8.02. Successor Substituted.

                  Upon any consolidation or merger or any sale, assignment,
conveyance, lease, transfer or other disposition of all or substantially all of
the assets of the Company in accordance with the foregoing in which the Company
or the Restricted Subsidiary, as the case may be, is not the continuing
corporation, the successor corporation formed by such a consolidation or into
which the Company or such Restricted Subsidiary is merged or to which such
transfer is made will succeed to, and be substituted for, and may exercise every
right and power of, the Company or such Restricted Subsidiary, as the case may
be, under this Indenture and the Notes with the same effect as if such successor
corporation had been named as the Company or such Restricted Subsidiary therein;
and thereafter, except in the case of (i) any lease or (ii) any sale,
assignment, conveyance, transfer, lease or other disposition to a Restricted
Subsidiary of the Company, the Company shall be discharged from all obligations
and covenants under this Indenture and the Notes.

                  For all purposes of this Indenture and the Notes (including
the provision of this Article Eight and Section 10.11, Section 10.13 and Section
10.16), Subsidiaries of any surviving entity will, upon such transaction or
series of related transactions, become Restricted Subsidiaries or Unrestricted
Subsidiaries as provided pursuant to Section 10.21 and all Indebtedness, and all
Liens on property or assets, of the Company and the Restricted Subsidiaries in
existence immediately prior to such transaction or series of related
transactions will be deemed to have been incurred upon such transaction or
series of related transactions.

in each case, such provisions shall not materially adversely affect the legal
rights of the Holders;

                  (d) to comply with the requirements of the SEC in order to
effect or maintain the qualification of this Indenture under the Trust Indenture
Act, as contemplated by Section 9.05 hereof or otherwise;

adversely affect the legal rights of any Holder; or

                  (g)  to add Guarantors with respect to the Notes;

provided, however, that the Company has delivered to the Trustee an Opinion of
Counsel stating that such change, agreement or waiver does not materially
adversely affect the legal rights of any Holder.

                  Section 9.02. Supplemental Indentures, Agreements and Waivers
                                with Consent of Holders.

                  With the written consent of the Holders of not less than a
majority of Accreted Value of the Outstanding Notes delivered to the Company and
the Trustee, the Company when authorized by a Board Resolution, together with
the Trustee, may amend, waive, modify or supplement any other provision of this
Indenture or the Notes; provided, however, that no such amendment, waiver,

each Outstanding Note affected thereby:

                     (i) reduce the principal amount of, or extend the fixed
         maturity of, or alter the redemption provisions of, the Notes, (other

         consent to take any action under this Indenture or the Notes,

                    (iv) impair the right to institute suit for the enforcement
         of any payment on or with respect to the Notes,

                   (vii) following the occurrence of a Change of Control or an

                  (viii) affect the ranking of the Notes in a manner adverse to
the holder of the Notes,

                    (ix) release any Guarantor from any of its obligations under
         its Guarantee or this Indenture except in compliance with the terms of
         this Indenture, or

                     (x) permit the creation of any Lien (other than the Lien as
         the Pledgee) created by the Escrow Agreement or terminate the Lien
         created by the Escrow Agreement.

                  Upon the written request of the Company accompanied by a copy
of a Board Resolution of the Board authorizing the execution of any such
supplemental indenture or other agreement, instrument or waiver, and an
Officers' Certificate and an Opinion of Counsel upon which the Trustee shall be
fully protected in relying upon as conclusive evidence that such change,
agreement, supplement or waiver is permitted by this Indenture and upon the
filing with the Trustee of evidence of the consent of Holders as aforesaid, the
Trustee shall join with the Company in the execution of such supplemental
indenture or other agreement, instrument or waiver.

                  It shall not be necessary for any Act of Holders under this
Section to approve the particular form of any proposed supplemental indenture or
other agreement, instrument or waiver, but it shall be sufficient if such Act
shall approve the substance thereof.

                  Section 9.03. Execution of Supplemental Indentures, Agreements
                                and Waivers.

                  In executing, or accepting the additional trusts created by,
any supplemental indenture, agreement, instrument or waiver permitted by this
Article Nine or the modifications thereby of the trusts created by this
Indenture, the Trustee shall be entitled to receive, and shall be fully
protected in relying upon, an Opinion of Counsel and an Officers' Certificate
from each obligor under the Notes entering into such supplemental indenture,
agreement, instrument or waiver, each stating that the execution of such
supplemental indenture, agreement, instrument or waiver (a) is authorized or
permitted by this Indenture and (b) does not violate the provisions of any
agreement or instrument evidencing any other Indebtedness of the Company or any
other Subsidiary of the Company. The Trustee may, but shall not be obligated to,
enter into any such supplemental indenture, agreement, instrument or waiver
which affects the Trustee's own rights, duties or immunities under this
Indenture, the Notes or otherwise.

                  Section 9.04. Effect of Supplemental Indentures.

                  Upon the execution of any supplemental indenture under this
Article Nine, this Indenture and/or the Notes, if applicable, shall be modified
in accordance therewith, and such supplemental indenture shall form a part of
this Indenture and/or the Notes, if applicable, as the case may be, for all
purposes; and every Holder of Notes theretofore or thereafter authenticated and
delivered hereunder shall be bound thereby.

                  Section 9.05. Conformity with Trust Indenture Act.

                  Every supplemental indenture executed pursuant to this Article
Nine shall conform to the requirements of the Trust Indenture Act as then in
effect.

                  Section 9.06. Reference in Notes to Supplemental Indentures.

                  Notes authenticated and delivered after the execution of any
supplemental indenture pursuant to this Article may, and shall if required by
the Trustee, bear a notation in form approved by the Trustee as to any matter
provided for in such supplemental indenture. If the Company shall so determine,
new Notes so modified as to conform, in the opinion of the Trustee and the
Board, to any such supplemental indenture may be prepared and executed by the
Company and authenticated and delivered by the Trustee upon a Company Order in
exchange for Outstanding Notes.

                  Section 9.07. Record Date.

                  The Company may, but shall not be obligated to, fix, a record
date for the purpose of determining the Holders entitled to consent to any
supplemental indenture, agreement or instrument or any waiver, and shall
promptly notify the Trustee of any such record date. If a record date is fixed
those persons who were Holders at such record date (or their duly designated
proxies), and only those persons, shall be entitled to consent to such
supplemental indenture, agreement or instrument or waiver or to revoke any
consent previously given, whether or not such persons continue to be Holders
after such record date. No such consent shall be valid or effective for more
than 90 days after such record date.

                  Section 9.08. Revocation and Effect of Consents.

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

                                   ARTICLE TEN

                                    COVENANTS

                  Section 10.01. Payment of Principal, Premium and Interest.

                  The Company shall duly and punctually pay the principal of,
premium, if any, and interest on the Notes in accordance with the terms of the
Notes and this Indenture.

                  Section 10.02. Maintenance of Office or Agency.

                  The Company shall maintain in the Borough of Manhattan in The
City of New York, State of New York, an office or agency where Notes may be
presented or surrendered for payment, where Notes may be surrendered for
registration of transfer or exchange and where notices and demands to or upon
the Company in respect of the Notes and this Indenture may be served. The office
of the Trustee at its Corporate Trust Office will be such office or agency of
the Company, unless the Company shall designate and maintain some other office
or agency for one or more of such purposes. The Company will give prompt written
notice to the Trustee of any change in the location of any such office or
agency. If at any time the Company shall fail to maintain any such required
office or agency or shall fail to furnish the Trustee with the address thereof,
such presentations, surrenders, notices and demands may be made or served at the
Corporate Trust Office of the Trustee, and the Company hereby appoints the
Trustee as its agent to receive all such presentations, surrenders, notices and
demands.

                  The Company may also from time to time designate one or more
other offices or agencies (in or outside of The City of New York, State of New
York) where the Notes may be presented or surrendered for any or all such
purposes, and may from time to time rescind such designation; 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 City of New York, State
of New York for such purposes. The Company will give prompt written notice to
the Trustee of any such designation or rescission and any change in the location
of any such other office or agency.

                  Section 10.03. Money for Note Payments To Be Held in Trust.

                  If the Company shall at any time act as its own Paying Agent,
it will, on or before each due date of the principal of, premium, if any, or
interest on any of the Notes, segregate and hold in trust for the benefit of the
Holders entitled thereto a sum sufficient to pay the principal, premium, if any,
or interest so becoming due until such sums shall be paid to such persons or
otherwise disposed of as herein provided, and will promptly notify the Trustee
of its action or failure so to act.

                  If the Company is not acting as Paying Agent, the Company
will, on or before each due date of the principal of, premium, if any, or
interest on, any Notes, deposit with a Paying Agent a sum in same day funds
sufficient to pay the principal, premium, if any, or interest so becoming due,
such sum to be held in trust for the benefit of the Holders entitled to such
principal, premium or interest, and (unless such Paying Agent is the Trustee)
the Company will promptly notify the Trustee of such action or any failure so to
act.

                  If the Company is not acting as Paying Agent, the Company will
cause each Paying Agent other than the Trustee to execute and deliver to the
Trustee an instrument in which such Paying Agent will agree with the Trustee,
subject to the provisions of this Section 10.03, that such Paying Agent will:

                  (a) hold all sums held by it for the payment of the principal
of, premium, if any, or interest on Notes in trust for the benefit of the
Holders entitled thereto until such sums shall be paid to such Holders or
otherwise disposed of as herein provided;

                  (b) give the Trustee notice of any Default by the Company (or
any other obligor upon the Notes) in the making of any payment of principal of,
premium, if any, or interest on the Notes;

                  (c) at any time during the continuance of any such Default,
upon the written request of the Trustee, forthwith pay to the Trustee all sums
so held in trust by such Paying Agent; and

                  (d) acknowledge, accept and agree to comply in all aspects
with the provisions of this Indenture relating to the duties, rights and
liabilities of such Paying Agent.

                  The Company may at any time, for the purpose of obtaining the
satisfaction and discharge of this Indenture or for any other purpose, pay, or
by Company Order direct any Paying Agent to pay, to the Trustee all sums held in
trust by the Company or such Paying Agent, such sums to be held by the Trustee
upon the same trusts as those upon which such sums were held by the Company or
such Paying Agent; and, upon such payment by any Paying Agent to the Trustee,
such Paying Agent will be released from all further liability with respect to
such money.

                  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 Note and remaining unclaimed for two years after such
principal, premium, if any, or interest has become due and payable shall be paid
to the Company upon receipt of a Company Request therefor, or (if then held by
the Company) will be discharged from such trust; and the Holder of such Note
will thereafter, as an unsecured general 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, will 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, at the option of the Company
in the New York Times or 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 publication, any unclaimed
balance of such money then remaining shall be repaid to the Company.

                  Section 10.04. Corporate Existence.

                  Subject to Article Eight, the Company shall do or cause to be
done all things necessary to preserve and keep in full force and effect the
corporate existence, rights (charter and statutory), licenses and franchises of
the Company and each of the Restricted Subsidiaries; provided, however, that the
Company will not be required to preserve any such right, license or franchise if
the Board shall determine that the preservation thereof is no longer desirable
in the conduct of the business of the Company and the Restricted Subsidiaries as
a whole and that the loss thereof is not adverse in any material respect to the
Holders; provided, further, that the foregoing will not prohibit a sale,
transfer or conveyance of a Subsidiary of the Company or any of its assets in
compliance with the terms of this Indenture.

                  Section 10.05. Payment of Taxes and Other Claims.

                  The Company shall pay or discharge or cause to be paid or
discharged, before the same shall become delinquent, (a) all material taxes,
assessments and governmental charges levied or imposed (i) upon the Company or
any of its Restricted Subsidiaries or (ii) upon the income, profits or property
of the Company or any of the Restricted Subsidiaries and (b) all material lawful
claims for labor, materials and supplies, which, if unpaid, could reasonably be
expected to become a Lien upon the property of the Company or any of the
Restricted Subsidiaries; provided, however, that the Company will not be
required to pay or discharge or cause to be paid or discharged any such tax,
assessment, charge or claim (x) whose amount, applicability or validity is being
contested in good faith by appropriate proceedings properly instituted and
diligently conducted or (y) if the failure to so pay, discharge or cause to be
paid or discharged could not reasonably be expected to have a Material Adverse
Effect (as defined in the Purchase Agreement).

                  Section 10.06. Maintenance of Properties.

                  The Company shall cause all material properties owned by the
Company or any of the Restricted Subsidiaries or used or held for use in the
conduct of their respective businesses to be maintained and kept in good
condition, repair and working order and supplied with all necessary equipment
and will cause to be made all necessary repairs, renewals, replacements,
betterments and improvements thereof, all as in the judgment of the Company may
be necessary so that the business carried on in connection therewith may be
properly and advantageously conducted at all times; provided, however, that
nothing in this Section 10.06 will prevent the Company from discontinuing the
maintenance of any of such properties if such discontinuance is, in the judgment
of the Company, desirable in the conduct of its business or the business of any
of the Restricted Subsidiaries and is not disadvantageous in any material
respect to the Holders.

                  Section 10.07. Insurance.

                  The Company shall at all times keep all of its and the
Restricted Subsidiaries' properties which are of an insurable nature insured
with insurers, believed by the Company in good faith to be financially sound and
responsible, against loss or damage to the extent that property of similar
character is usually and customarily so insured by corporations similarly
situated and owning like properties.

                  Section 10.08. Books and Records.

                  The Company shall keep proper books of record and account, in
which full and correct entries will be made of all financial transactions and
the assets and business of the Company and each Restricted Subsidiary and each
Restricted Affiliate of the Company in material compliance with GAAP.

                  Section 10.09. Provision of Financial Statements.

                  The Company shall file with the SEC (so long as the SEC will
accept any such filings), the Trustee and the Initial Purchasers the annual
reports, quarterly reports and other documents required to be filed with the SEC
pursuant to Sections 13 and 15 of the Exchange Act, whether or not the Company
has a class of securities registered under the Exchange Act. The Company will
also comply with the other provisions of Section 314(a) of the Trust Indenture
Act.

                  Section 10.10. Change of Control.

                  Upon the occurrence of a Change of Control (the date of such
occurrence being the "Change of Control Date"), the Company shall make an offer
to purchase (the "Change of Control Offer"), on a business day (the "Change of
Control Payment Date") not later than 60 days following the Change of Control
Date, all Notes then outstanding at a purchase price equal to 101% of the
Accreted Value thereof on any Change of Control Payment Date, plus accrued and
unpaid interest, if any, to any Change of Control Payment Date. Notice of a
Change of Control Offer shall be given to Holders and the Trustee not less than
25 days nor more than 45 days before the Change of Control Payment Date. The
Change of Control Offer is required to remain open for at least 20 business days
and until the close of business on the Change of Control Payment Date. Failure
to mail the notice of a Change of Control Offer on the date specified below or
to have satisfied the foregoing condition precedent by the date that such notice
is required to be mailed will constitute a Default under Section 5.01(iv).

                  Notice of a Change of Control Offer shall be mailed by the
Company not more than 20 Business Days after the Change of Control Date to the
Holders of Notes at their last registered addresses with a copy to the Trustee
and the Paying Agent. The Change of Control Offer shall remain open from the
time of mailing for at least 20 Business Days and until 5:00 p.m., New York City
time, on the Change of Control Payment Date. The notice, which shall govern the
terms of the Change of Control Offer, shall include such disclosures as are
required by law and shall state:

                  (a) that the Change of Control Offer is being made pursuant to
this Section 10.10 and that all Notes tendered into the Change of Control Offer
will be accepted for payment;

                  (b) the purchase price (including the amount of accrued
interest, if any) for each Note, the Change of Control Payment Date and the date
on which the Change of Control Offer expires;

                  (c) that any Note not tendered for payment will continue to
accrete Accreted Value or accrue interest in accordance with the terms thereof;

                  (d) that, unless the Company shall default in the payment of
the purchase price, any Note accepted for payment pursuant to the Change of
Control Offer shall cease to accrete Accrued Interest or accrue interest after
the Change of Control Payment Date;

                  (e) that Holders electing to have Notes purchased pursuant to
a Change of Control Offer will be required to surrender their Notes to the
Paying Agent at the address specified in the notice prior to 5:00 p.m., New York
City time, on the Change of Control Payment Date and must complete any form
letter of transmittal proposed by the Company and acceptable to the Trustee and
the Paying Agent;

                  (f) that Holders of Notes will be entitled to withdraw their
election if the Paying Agent receives, not later than 5:00 p.m., New York City
time, on the Change of Control Payment Date, a facsimile transmission or letter
setting forth the name of the Holders, the principal amount of Notes the Holders
delivered for purchase, the Note certificate number (if any) and a statement
that such Holder is withdrawing his election to have such Notes purchased;

                  (g) that Holders whose Notes are purchased only in part will
be issued Notes of like tenor equal in principal amount to the unpurchased
portion of the Notes surrendered;

                  (h) the instructions that Holders must follow in order to
tender their Notes; and

                  (i) information concerning the business of the Company, the
most recent annual and quarterly reports of the Company filed with the SEC
pursuant to the Exchange Act (or, if the Company is not required to file any
such reports with the SEC, the comparable reports prepared pursuant to Section
10.09), a description of material developments in the Company's business,
information with respect to pro forma historical financial information after
giving effect to such Change of Control and such other information concerning
the circumstances and relevant facts regarding such Change of Control and Change
of Control Offer as would, in the good faith judgment of the Company, be
material to a Holder of Notes in connection with the decision of such Holder as
to whether or not it should tender Notes pursuant to the Change of Control
Offer.

                  On the Change of Control Payment Date, the Company will (i)
accept for payment Notes or portions thereof tendered pursuant to the Change of
Control Offer, (ii) deposit with the Paying Agent money, in immediately
available funds, sufficient to pay the purchase price of all Notes or portions
thereof so tendered and accepted and (iii) deliver to the Trustee the Notes so
accepted together with an Officers' Certificate setting forth the Notes or
portions thereof tendered to and accepted for payment by the Company. The Paying
Agent will promptly mail or deliver to the Holders of Notes so accepted payment
in an amount equal to the purchase price, and the Trustee shall promptly
authenticate and mail or deliver to such Holders a new Note of like tenor equal
in principal amount to any unpurchased portion of the Note surrendered. Any
Notes not so accepted shall be promptly mailed or delivered by the Company to
the Holder thereof. The Company will publicly announce the results of the Change
of Control Offer not later than the first Business Day following the Change of
Control Payment Date. Except as described above with respect to a Change of
Control, this Indenture does not contain provisions that permit the Holders to
require that the Company repurchase or redeem the Notes in the event of a
takeover, recapitalization or similar transaction which may be highly leveraged.
If a Change of Control Offer is made, there can be no assurance that the Company
will have available funds sufficient to pay for all of the Notes that might be
delivered by holders of Notes seeking to accept the Change of Control Offer. The
Company shall not be required to make a Change of Control Offer following a
Change of Control if a third party makes the Change of Control Offer in the
manner, at the times and otherwise in compliance with the requirements
applicable to a Change of Control Offer made by the Company and purchases all
Notes validly tendered and not withdrawn under such Change of Control Offer.

                  If the Company is required to make a Change of Control Offer,
the Company will comply with all applicable tender offer laws and regulations,
including, to the extent applicable, Section 14(e) and Rule 14e-1 under the
Exchange Act, and any other applicable securities laws and regulations. To the
extent that the provisions of any securities laws or regulations conflict with
the provisions of this Section 10.10, the Company will comply with the
applicable securities laws and regulations and shall not be deemed to have
breached its obligations under this Section 10.10 by virtue thereof.

                  Section 10.11. Limitation on Additional Indebtedness.

                  The Company shall not, and shall not permit any Restricted
Subsidiary or Restricted Affiliate to, directly or indirectly, create, incur,
assume, issue, guarantee or in any manner become directly or indirectly liable
for or with respect to, contingently or otherwise, the payment of (collectively
to "incur") any Indebtedness (including any Acquired Indebtedness), except for
Permitted Indebtedness; provided, that (A)(i) the Company will be permitted to
incur Indebtedness (including Acquired Indebtedness and Buildout Indebtedness)
and (ii) a Restricted Subsidiary or Restricted Affiliate will be permitted to
incur Acquired Indebtedness or Buildout Indebtedness, if, in either case,
immediately after giving pro forma effect to such incurrence (including the
application of the net proceeds therefrom), either (X) the ratio of Total
Consolidated Indebtedness to Consolidated Pro Forma Operating Cash Flow would
not be greater than or equal to 5.5 to 1.0 if such Indebtedness is incurred
prior to October 15, 2000 or 5.0 to 1.0 if such Indebtedness is incurred on or
after October 15, 2000 or (Y) the ratio of Total Consolidated Indebtedness to
Total Invested Equity Capital would not exceed 2.0 to 1.0 and (B) on or after
October 15, 2002, a Restricted Affiliate will be permitted to incur Acquired
Indebtedness or Buildout Indebtedness, if, after giving pro forma effect to such
incurrence (including the application of the net proceeds therefrom), the ratio
of Total Affiliate Indebtedness to Affiliate Pro Forma Operating Cash Flow of
such Restricted Affiliate would not be greater than or equal to 4.0 to 1.0.

                  For purposes of determining compliance with this Section
10.11, in the event that an item of Indebtedness meets the criteria of more than
one of the types of Indebtedness permitted by this covenant, the Company in its
sole discretion shall classify such item of Indebtedness and only be required to
include the amount of such Indebtedness as one of such types.

                  Section 10.12. Statement by Officers as to Default.

                  The Company will deliver to the Trustee, within 120 days after
the end of each fiscal year of the Company ending after the date hereof, a
written statement signed by the chairman or a chief executive officer, the
principal financial officer or principal accounting officer of the Company,
stating (i) that a review of the activities of the Company 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 (ii) that, to the knowledge
of each officer signing such certificate, the Company has kept, observed,
performed and fulfilled each and every covenant and condition contained in this
Indenture and is not in default in the performance or observance of any of the
terms, provisions, conditions and covenants hereof (or, if a Default shall have
occurred, describing all such Defaults of which such officers may have
knowledge, their status and what action the Company is taking or proposes to
take with respect thereto). When any Default under this Indenture has occurred
and is continuing, or if the Trustee or any Holder or the trustee for or the
holder of any other evidence of Indebtedness of the Company or any Restricted
Subsidiary gives any notice or takes any other action with respect to a claimed
default (other than with respect to Indebtedness (other than Indebtedness
evidenced by the Notes) in the principal amount of less than $1.0 million), the
Company will promptly notify the Trustee of such Default, notice or action and
will deliver to the Trustee by registered or certified mail or by telegram, or
facsimile transmission followed by hard copy by registered or certified mail an
Officers' Certificate specifying such event, notice or other action within five
Business Days after the Company becomes aware of such occurrence and what action
the Company is taking or proposes to take with respect thereto.

                  Section 10.13. Limitation on Restricted Payments.

                  The Company shall not, and shall not permit any of the
Restricted Subsidiaries or Restricted Affiliates to, make, directly or
indirectly, any Restricted Payment unless:

                     (i) no Default shall have occurred and be continuing at the
         time of or upon giving effect to such Restricted Payment;

                    (ii) immediately after giving effect to such Restricted
         Payment, the Company would be able to incur $1.00 of Indebtedness under
         clause (A)(X) of the proviso of Section 10.11 hereof; and

                   (iii) immediately after giving effect to such Restricted
         Payment, the aggregate amount of all Restricted Payments declared or
         made on or after the Issue Date and all Designation Amounts does not
         exceed an amount equal to the sum of, without duplication, (a) 50% of
         the cumulative Consolidated Net Income accrued on a cumulative basis
         during the period beginning on January 1, 1998 and ending on the last
         day of the fiscal quarter of the Company immediately preceding the date
         of such proposed Restricted Payment (or, if such cumulative
         Consolidated Net Income for such period is a deficit, minus 100% of
         such deficit), plus (b) the aggregate net cash proceeds received by the
         Company from the issue or sale (other than to a Restricted Subsidiary
         or Restricted Affiliate of the Company) of its Capital Stock (other
         than Disqualified Stock) on or after the Issue Date (including, without
         duplication, upon exercise of warrants, options or rights), plus (c)
         the aggregate net proceeds received by the Company from the issuance
         (other than to a Restricted Subsidiary or to a Restricted Affiliate of
         the Company) on or after the Issue Date of its Capital Stock (other
         than Disqualified Stock) upon the conversion of, or exchange for,
         Indebtedness of the Company or a Restricted Subsidiary, plus (d) in the
         case of the disposition or repayment of any Investment constituting a
         Restricted Payment made other than an Investment made pursuant to
         clause (c), (f) or (g) of the following paragraph made after the Issue
         Date, an amount equal to the lesser of the return of capital with
         respect to such Investment and the cost of such Investment, in either
         case, less the cost of the disposition of such Investment, plus (e) in
         the case of any Revocation of the Designation of a Subsidiary as an
         Unrestricted Subsidiary, an amount equal to the consolidated net
         Investment in such Subsidiary on the date of Revocation but not in an
         amount exceeding the net amount of any Investments constituting
         Restricted Payments made (or deemed made) in such Subsidiary after the
         Issue Date plus (f) in the case of the JV Designation after the Issue
         Date of a New Joint Venture as a Restricted Affiliate, an amount equal
         to the consolidated net Investment in such New Joint Venture on the
         date of such JV Designation but not in an amount exceeding the net
         amount of any Investments constituting Restricted Payments made (or
         deemed made) in such New Joint Venture after the Issue Date. For
         purposes of the preceding clauses (b) and (c) and without duplication,
         the value of the aggregate net cash proceeds received by the Company
         upon the issuance of Capital Stock either upon the conversion of
         convertible Indebtedness or in exchange for outstanding Indebtedness or
         upon the exercise of options, warrants or rights will be the net cash
         proceeds received upon the issuance of such Indebtedness, options,
         warrants or rights plus the incremental amount received by the Company
         upon the conversion, exchange or exercise thereof.

For purposes of determining the amount expended for Restricted Payments, cash
distributed shall be valued at the face amount thereof and property other than
cash shall be valued at its Fair Market Value.

                  The provisions of this Section 10.13 shall not prohibit (each
of which shall be given independent effect):

                  (a) the payment of any dividend or other distribution within
         60 days after the date of declaration thereof, if at such date of
         declaration such payment would comply with the provisions of this
         Indenture;

                  (b) so long as no Default shall have occurred and be
         continuing, the purchase, redemption, retirement or other acquisition
         of any shares of Capital Stock of the Company (A) in exchange for or
         conversion into or (B) out of the net cash proceeds of the
         substantially concurrent issue and sale (other than to a Restricted
         Subsidiary or to a Restricted Affiliate) of shares of Capital Stock of
         the Company (other than Disqualified Stock); provided that any such net
         cash proceeds pursuant to the immediately preceding subclause (B) are
         excluded from clause (iii)(b) of the preceding paragraph;

                  (c) so long as no Default shall have occurred and be
         continuing, the purchase, redemption, defeasance or other acquisition
         or retirement for value of Subordinated Indebtedness made by exchange
         for (including any such exchange pursuant to the exercise of a
         conversion right or privilege in which cash is paid in lieu of
         fractional shares or scrip), or out of the net cash proceeds of, a
         substantially concurrent issue or sale (other than to a Restricted
         Subsidiary or to a Restricted Affiliate) of (A) Capital Stock (other
         than Disqualified Stock) of the Company; provided that any such net
         cash proceeds, to the extent so used, are excluded from clause (iii)(b)
         of the preceding paragraph, and/or (B) other Subordinated Indebtedness,
         having an Average Life to Stated Maturity that is equal to or greater
         than the Average Life to Stated Maturity of the Subordinated
         Indebtedness being purchased, redeemed, defeased or otherwise acquired
         or retired;

                  (d) so long as no Default shall have occurred and be
         continuing, any Investment constituting a Restricted Payment made by
         the Company or any Restricted Subsidiary in any Restricted Affiliate to
         fund the capital requirements for financing or supporting a Permitted
         Business of such Restricted Affiliate;

                  (e) so long as no Default shall have occurred and be
         continuing, Investments constituting a Restricted Payment made by the
         Company or any Restricted Subsidiary in any person (including any
         Unrestricted Subsidiary or a Restricted Affiliate) in an amount not to
         exceed $10 million in the aggregate at any time outstanding;

                  (f) so long as no Default shall have occurred and be
         continuing, the making of a direct or indirect Investment constituting
         a Restricted Payment out of the proceeds of the issue or sale (other
         than to a Subsidiary or to a Restricted Affiliate) of Capital Stock
         (other than Disqualified Stock) of the Company; provided that any such
         net cash proceeds are excluded from clause (iii)(b) of the preceding
         paragraph; or

                  (g) so long as no Default shall have occurred and be
         continuing, any Investment constituting a Restricted Payment made in
         Megacable S.A. de C.V. not to exceed $20 million in the aggregate at
         any time outstanding.

                  Restricted Payments of the type set forth in the preceding
clauses (e) and (g) shall be included in making the determination of available
amounts under clause (iii) of the preceding paragraph to the extent they are
outstanding.

                  In no event shall a Restricted Payment made on the basis of
consolidated financial statements prepared in good faith in accordance with GAAP
be subject to rescission or constitute a Default by reason of any requisite
subsequent restatement of such financial statements which would have made such
Restricted Payment prohibited at the time that it was made.

                  Section 10.14. Limitation on Transactions with Affiliates.

                  The Company shall not, and shall not permit, cause or suffer
any Restricted Subsidiary to, conduct any business or enter into any transaction
(or series of related transactions which are similar or part of a common plan)
with or for the benefit of any of their respective Affiliates or any beneficial
holder of 10% or more of the Common Stock of the Company or any officer or
director of the Company (each, an "Affiliate Transaction"), unless the terms of
the Affiliate Transaction are set forth in writing, and are fair and reasonable
to the Company or such Restricted Subsidiary, as the case may be. Each Affiliate
Transaction involving aggregate payments or other Fair Market Value in excess of
$5 million shall be approved by a majority of the Board, such approval to be
evidenced by a Board Resolution stating that the Board has determined that such
transaction or transactions comply with the foregoing provisions. In addition to
the foregoing, each Affiliate Transaction involving aggregate consideration of
$10 million or more shall be approved by a majority of the Disinterested
Directors; provided that, in lieu of such approval by the Disinterested
Directors, the Company may obtain a written opinion from an Independent
Financial Advisor stating that the terms of such Affiliate Transaction to the
Company or the Restricted Subsidiary, as the case may be, are fair from a
financial point of view. In addition, a Restricted Affiliate shall not enter
into any transaction (or series of related transactions which are similar or
part of a common plan) with or for the benefit of the Other Partner, unless the
terms of such transaction or transactions are in writing, and are fair and
reasonable to such Restricted Affiliate. For purposes of this covenant, any
Affiliate Transaction approved by a majority of the Disinterested Directors or
as to which a written opinion has been obtained from an Independent Financial
Advisor, on the basis set forth in the preceding sentence, shall be deemed to be
on terms that are fair and reasonable to the Company and the Restricted
Subsidiaries, as the case may be, and therefore shall be permitted under this
covenant.

                  Notwithstanding the foregoing, the restrictions set forth in
this covenant shall not apply to (i) transactions with or among, or solely for
the benefit of, the Company and/or any of the Restricted Subsidiaries, (ii)
transactions pursuant to agreements and arrangements existing on the Issue Date,
(iii) transactions among any of the Company or the Restricted Subsidiaries, on
the one hand, and any of the Restricted Affiliates, on the other hand, provided
that such transactions are in the ordinary course of business and are related to
or in furtherance of a Permitted Business, (iv) dividends paid by the Company
pursuant to and in compliance with this Section 10.13, (v) customary directors'
fees, indemnification and similar arrangements, consulting fees, employee
salaries bonuses, employment agreements and arrangements, compensation or
employee benefit arrangements or legal fees and (vi) grants of customary
registration rights with respect to securities of the Company.

                  Section 10.15. Disposition of Proceeds of Asset Sales.

                  The Company shall not, and shall not permit any Restricted
Subsidiary or Restricted Affiliate to, make any Asset Sale unless (a) the
Company or such Restricted Subsidiary or such Restricted Affiliate, as the case
may be, receives consideration at the time of such Asset Sale at least equal to
the Fair Market Value of the shares or assets sold or otherwise disposed of and
(b) at least 75% of such consideration consists of cash or Cash Equivalents;
provided that the amount of any liabilities (other than Subordinated
Indebtedness or Indebtedness of a Restricted Subsidiary that would not
constitute Restricted Subsidiary Indebtedness) that are assumed by the
transferee of any such assets pursuant to an agreement that unconditionally
releases the Company or such Restricted Subsidiary or Restricted Affiliate, as
the case may be, from further liability shall be treated as cash for purposes of
this Section 10.15. The Company or the applicable Restricted Subsidiary, as the
case may be, may (i) apply the Net Cash Proceeds from any such Asset Sale by the
Company or a Restricted Subsidiary and the Net Cash Proceeds of any Asset Sale
by a Restricted Affiliate to the extent distributed to the Company or a
Restricted Subsidiary within 365 days of the receipt thereof to repay an amount
of Indebtedness (other than Subordinated Indebtedness) of the Company in an
amount not exceeding the Other Senior Debt Pro Rata Share and elect to
permanently reduce the amount of the commitments thereunder by the amount of the
Indebtedness so repaid, (ii) apply the Net Cash Proceeds from such Asset Sale by
the Company or a Restricted Subsidiary and the Net Cash Proceeds of any Asset
Sale by a Restricted Affiliate to the extent distributed to the Company or a
Restricted Subsidiary to repay any Restricted Subsidiary Indebtedness and elect
to permanently reduce the commitments thereunder by the amount of the
Indebtedness so repaid or (iii) apply the Net Cash Proceeds from any Asset Sale
by the Company or a Restricted Subsidiary and the Net Cash Proceeds of any Asset
Sale by a Restricted Affiliate to the extent distributed to the Company or a
Restricted Subsidiary within 365 days thereof, to an investment in properties
and assets that will be used in a Permitted Business (or in Capital Stock and
other securities of any person that will become a Restricted Subsidiary or
Restricted Affiliate as a result of such investment to the extent such person
owns properties and assets that will be used in a Permitted Business) of the
Company or any Restricted Subsidiary ("Replacement Assets"). Notwithstanding
anything herein to the contrary, in the event of any Asset Sale of all or
substantially all of the properties or assets of any Restricted Affiliate Group,
whether in a single transaction or series of related transactions, the
Restricted Affiliate Group shall be required to distribute the Net Cash Proceeds
therefrom, after providing for all Indebtedness and other liabilities of such
Restricted Affiliate Group, to the Company or a Restricted Subsidiary and the
Other Partner on a pro rata basis in accordance with their respective equity
interests. Any Net Cash Proceeds from any Asset Sale that are neither used to
repay, and permanently reduce the commitments under, any Restricted Subsidiary
Indebtedness as set forth in clause (ii) of the preceding sentence or invested
in Replacement Assets within the 365-day period as set forth in clause (iii)
shall constitute "Excess Proceeds." Any Excess Proceeds not used as set forth in
clause (i) of the second preceding sentence shall constitute "Offer Excess
Proceeds" subject to disposition as provided below.

                  When the aggregate amount of Offer Excess Proceeds equals or
exceeds $10.0 million, the Company shall make an offer to purchase (an "Asset
Sale Offer"), from all Holders issued under this Indenture, that aggregate
principal amount of Notes as can be purchased by application of such Offer
Excess Proceeds at a price in cash equal to 100% of the principal amount thereof
plus, in each case, accrued and unpaid interest, if any, to the purchase date.
Each Asset Sale Offer shall remain open for a period of 20 business days or such
longer period as may be required by law. To the extent that the aggregate
purchase price for the applicable issue of Notes tendered pursuant to an Asset
Sale Offer is less than the Offer Excess Proceeds, the Company or any Restricted
Subsidiary may use such deficiency for general corporate purposes. If the
aggregate purchase price for the Notes validly tendered and not withdrawn by
holders thereof exceeds the amount of Notes which can be purchased with the
Offer Excess Proceeds, Notes to be purchased will be selected on a pro rata
basis. Upon completion of such Asset Sale Offer, the amount of Offer Excess
Proceeds shall be reset to zero.

                  Notwithstanding the two immediately preceding paragraphs, the
Company, the Restricted Subsidiaries and the Restricted Affiliates will be
permitted to consummate an Asset Sale without complying with such paragraphs to
the extent (i) at least 75% of the consideration of such Asset Sale constitutes
Replacement Assets, cash or Cash Equivalents (including obligations deemed to be
cash under this covenant) and (ii) such Asset Sale is for Fair Market Value;
provided that any consideration constituting (or deemed to constitute) cash or
Cash Equivalents received by the Company, any of the Restricted Subsidiaries or
any of the Restricted Affiliates in connection with any Asset Sale permitted to
be consummated under this paragraph shall constitute Net Cash Proceeds subject
to the provisions of the two preceding paragraphs.

                  Notice of an Asset Sale Offer shall be mailed by the Company
not more than 20 Business Days after the obligation to make such Asset Sale
Offer arises to the Holders of Notes at their last registered addresses with a
copy to the Trustee and the Paying Agent. The Asset Sale Offer shall remain open
from the time of mailing for at least 20 Business Days and until 5:00 p.m., New
York City time, on the date fixed for Purchase of Notes validly tendered and not
withdrawn, which date shall be not later than the 30th Business Day following
the mailing of such Asset Sale Offer (the "Asset Sale Offer Purchase Date"). The
notice, which shall govern the terms of the Asset Sale Offer, shall include such
disclosures as are required by law and shall state:

                  (a) that the Asset Sale Offer is being made pursuant to this
         Section 10.15 and that the Asset Sale Offer shall remain open for a
         period of 20 Business Days or such longer period as may be required by
         law;

                  (b) the purchase price (including the amount of accrued
         interest, if any) for each Note, the Asset Sale Offer Purchase Date and
         the date on which the Asset Sale Offer expires;

                  (c) that any Note not tendered for payment will continue to
         accrue interest in accordance with the terms thereof;

                  (d) that, unless the Company shall default in the payment of
         the purchase price, any Note accepted for payment pursuant to the Asset
         Sale Offer shall cease to accrue interest after the Asset Sale Offer
         Purchase Date;

                  (e) that Holders electing to have Notes purchased pursuant to
         an Asset Sale Offer will be required to surrender their Notes to the
         Paying Agent at the address specified in the notice prior to 5:00 p.m.,
         New York City time, on the Asset Sale Offer Purchase Date and must
         complete any form letter of transmittal proposed by the Company and
         acceptable to the Trustee and the Paying Agent;

                  (f) that Holders of Notes will be entitled to withdraw their
         election if the Paying Agent receives, not later than 5:00 p.m., New
         York City time, on the Asset Sale Offer Purchase Date, a facsimile
         transmission or letter setting forth the name of the Holders, the
         principal amount of Notes the Holders delivered for purchase, the Note
         certificate number (if any) and a statement that such Holder is
         withdrawing his election to have such Notes purchased;

                  (g) that Holders whose Notes are purchased only in part will
         be issued Notes of like tenor equal in principal amount to the
         unpurchased portion of the Notes surrendered;

                  (h) the instructions that Holders must follow in order to
         tender their Notes; and

                  (i) information concerning the business of the Company, the
         most recent annual and quarterly reports of the Company filed with the
         Commission pursuant to the Exchange Act (or, if the Company is not
         required to file any such reports with the SEC, the comparable reports
         prepared pursuant to Section 10.24), a description of material
         developments in the Company's business, information with respect to pro
         forma historical financial information after giving effect to such
         Asset Sale and such other information concerning the circumstances and
         relevant facts regarding such Asset Sale and Asset Sale Offer as would,
         in the good faith judgment of the Company, be material to a Holder of
         Notes in connection with the decision of such Holder as to whether or
         not it should tender Notes pursuant to the Asset Sale Offer.

                  On the Asset Sale Offer Purchase Date, the Company will (i)
accept for payment Notes or portions thereof tendered pursuant to the Asset Sale
Offer, (ii) deposit with the Paying Agent money, in immediately available funds,
sufficient to pay the purchase price of all Notes or portions thereof so
tendered and accepted and (iii) deliver to the Trustee the Notes so accepted
together with an Officers' Certificate setting forth the Notes or portions
thereof tendered to and accepted for payment by the Company. The Paying Agent
will promptly mail or deliver to the Holders of Notes so accepted payment in an
amount equal to the purchase price, and the Trustee shall promptly authenticate
and mail or deliver to such Holders a new Note of like tenor equal in principal
amount to any unpurchased portion of the Note surrendered. Any Notes not so
accepted shall be promptly mailed or delivered by the Company to the Holder
thereof. The Company will publicly announce the results of the Asset Sale Offer
not later than the first Business Day following the Asset Sale Offer Purchase
Date.

                  If the Company is required to make an Asset Sale Offer, the
Company shall comply with all applicable tender offer rules, including to the
extent applicable, Section 14(e) and Rule 14e-1 under the Exchange Act, and any
other applicable securities laws or regulations.

                  Section 10.16. Limitation on Liens Securing Certain
                                 Indebtedness.

                  The Company shall not, and shall not permit any Restricted
Subsidiary or Restricted Affiliate to, create, incur, assume or suffer to exist
any Liens of any kind against or upon (i) any property or assets of the Company
or any Restricted Subsidiary or Restricted Affiliate, whether now owned or
hereafter acquired, or any proceeds therefrom, which secure either (x)
Subordinated Indebtedness, unless the Notes are secured by a Lien on such
property, assets or proceeds that is senior in priority to the Liens securing
such Subordinated Indebtedness or (y) Senior Debt Securities, unless the Notes
are equally and ratably secured with the Liens securing the Senior Debt
Securities other than the Lien on the escrow account in favor of the escrow
agent and the trustee in respect of the Senior Notes and similar interest escrow
arrangements.

                  Section 10.17. Limitation on Business.

                  The Company shall not, and will not permit any of the
Restricted Subsidiaries or Restricted Affiliates to, engage in a business which
is not substantially a Permitted Business.

                  Section 10.18. Limitation on Certain Guarantees
                                 and Indebtedness of Restricted Subsidiaries
                                 and Restricted Affiliates.

                  The Company shall not permit any Restricted Subsidiary or
Restricted Affiliate, directly or indirectly, to assume, guarantee or in any
other manner become liable whether as issuer, guarantor or co-obligor, with
respect to (i) any Subordinated Indebtedness or (ii) any Senior Debt Securities
unless, in each case, such Restricted Subsidiary or Restricted Affiliate
simultaneously executes and delivers a supplemental indenture providing for the
guarantee of payment of the Notes by such Restricted Subsidiary or Restricted
Affiliate, as the case may be, on a basis senior to any such Subordinated
Indebtedness or pari passu with any such Senior Debt Securities, as the case may
be. Each guarantee of the Notes created pursuant to such provisions is referred
to as a "Guarantee" and the issuer of each such Guarantee, so long as the
Guarantee remains outstanding, is referred to as a "Guarantor."

                  Notwithstanding the foregoing, in the event of the
unconditional release of any Guarantor from its obligations in respect of the
Indebtedness which gave rise to the requirement that a Guarantee be given, such
Guarantor shall be released from all obligations under its Guarantee. In
addition, upon any sale or disposition (by merger or otherwise) of any Guarantor
by the Company or a Restricted Subsidiary to any person that is not an Affiliate
of the Company or any of the Restricted Subsidiaries which is otherwise in
compliance with the terms of this Indenture and as a result of which such
Guarantor ceases to be a Restricted Subsidiary of the Company, such Guarantor
will be deemed to be automatically and unconditionally released from all
obligations under its Guarantee; provided that each such Guarantor is sold or
disposed of in accordance with Section 10.15 hereof.

                  Section 10.19. Limitation on Issuances and Sales of Preferred
                                 Stock by Restricted Subsidiaries and
                                 Restricted Affiliates.

                  The Company (i) shall not permit any Restricted Subsidiary to
issue any Preferred Stock (other than to the Company or a Restricted Subsidiary)
and (ii) shall not permit any person (other than the Company or a Restricted
Subsidiary) to own any Preferred Stock of any Restricted Subsidiary. In
addition, the Company (i) shall not permit any Restricted Affiliate to issue any
Preferred Stock (other than (x) to the Company or a Restricted Subsidiary or (y)
to the holders of Common Stock in such Restricted Affiliate on a pro rata basis
based upon their ownership of Common Stock) or (ii) will not permit any person
not referred to in the preceding parenthetical of clause (i) of this sentence to
own any Preferred Stock of any Restricted Affiliate.

                  Section 10.20. Limitation on Dividends and Other Payment
                                 Restrictions Affecting Restricted
                                 Subsidiaries or Restricted Affiliates.

                  The Company shall not, and shall not permit any Restricted
Subsidiary or Restricted Affiliate to, directly or indirectly, create or
otherwise enter into or cause to become effective any consensual encumbrance or
consensual restriction of any kind on the ability of any Restricted Subsidiary
or Restricted Affiliate to (a) pay dividends, in cash or otherwise, or make any
other distributions on its Capital Stock or any other interest or participation
in, or measured by, its profits to the extent owned by the Company or any
Restricted Subsidiary or Restricted Affiliate, (b) pay any Indebtedness owed to
the Company or any Restricted Subsidiary or Restricted Affiliate, (c) make any
Investment in the Company or any other Restricted Subsidiary or Restricted
Affiliate or (d) transfer any of its properties or assets to the Company or to
any Restricted Subsidiary or Restricted Affiliate, except for (i) any
encumbrance or restriction in existence on the Issue Date, (ii) customary
non-assignment provisions, (iii) any encumbrance or restriction pertaining to an
asset subject to a Lien to the extent set forth in the security documentation
governing such Lien, (iv) any encumbrance or restriction applicable to a
Restricted Subsidiary or Restricted Affiliate at the time that it becomes a
Restricted Subsidiary or Restricted Affiliate that is not created in
contemplation thereof, (v) any encumbrance or restriction existing under any
agreement that refinances or replaces an agreement containing a restriction
permitted by clause (iv) above; provided that the terms and conditions of any
such encumbrance or restriction are not materially less favorable to the Holders
than those under or pursuant to the agreement being replaced or the agreement
evidencing the Indebtedness refinanced, (vi) any encumbrance or restriction
imposed upon a Restricted Subsidiary or Restricted Affiliate pursuant to an
agreement which has been entered into for the sale or disposition of all or
substantially all of the Capital Stock or assets of such Restricted Subsidiary
or Restricted Affiliate or any Asset Sale to the extent limited to the Capital
Stock or assets in question, and (vii) any customary encumbrance or restriction
applicable to a Restricted Subsidiary or Restricted Affiliate that is contained
in an agreement or instrument governing or relating to Indebtedness contained in
any Permitted Credit Facility; provided that (subject to customary net worth,
leverage, invested capital and other financial covenants) the provisions of such
agreement permit the payment of interest and principal and mandatory repurchases
pursuant to the terms of this Indenture and the Notes and other indebtedness
that is solely an obligation of the Company; provided further that such
agreement may contain customary covenants regarding the merger of or sale of all
or any substantial part of the assets of the Company or any Restricted
Subsidiary or Restricted Affiliate, customary restrictions on transactions with
affiliates, and customary subordination provisions governing indebtedness owed
to the Company or any Restricted Subsidiary or Restricted Affiliate.

                  Section 10.21. Designations of
                                 Unrestricted Subsidiaries.

                  The Company shall not designate any Subsidiary of the Company
(other than a newly created Subsidiary in which no Investment has previously
been made) as an "Unrestricted Subsidiary" under this Indenture (a
"Designation") unless:

                  (a) no Default shall have occurred and be continuing at the
         time of or after giving effect to such Designation;

                  (b) except in the case of a Permitted Investment or an
         Investment made pursuant to clause (iii) or (iv) of the second
         paragraph of Section 10.13 hereof, immediately after giving effect to
         such Designation, the Company would be able to incur $1.00 of
         Indebtedness under clause (A)(X) of the proviso of Section 10.11
         hereof; and

                  (c) the Company would not be prohibited under this Indenture
         from making an Investment at the time of Designation (assuming the
         effectiveness of such Designation) in an amount (the "US Designation
         Amount") equal to the Fair Market Value of the net Investment of the
         Company or any other Restricted Subsidiary in such Restricted
         Subsidiary on such date.

                  In the event of any such Designation, the Company shall be
deemed to have made an Investment constituting a Restricted Payment pursuant to
Section 10.13 hereof for all purposes of this Indenture in the US Designation
Amount. Neither the Company nor any Restricted Subsidiary shall at any time (x)
provide a guarantee of, or similar credit support to, any Indebtedness of any
Unrestricted Subsidiary (including any undertaking, agreement or instrument
evidencing such Indebtedness); provided that the Company may pledge Capital
Stock or Indebtedness of any Unrestricted Subsidiary on a nonrecourse basis such
that the pledgee has no claim whatsoever against the Company other than to
obtain such pledged property, (y) be directly or indirectly liable for any
Indebtedness of any Unrestricted Subsidiary or (z) be directly or indirectly
liable for any other Indebtedness which provides that the holder thereof may
(upon notice, lapse of time or both) declare a default thereon (or cause the
payment thereof to be accelerated or payable prior to its final scheduled
maturity) upon the occurrence of a default with respect to any other
Indebtedness that is Indebtedness of an Unrestricted Subsidiary, including any
corresponding right to take enforcement action against such Unrestricted
Subsidiary, except in the case of clause (x) or (y) to the extent permitted
under Section 10.13 and Section 10.14 hereof.

                  The Company will not revoke any Designation of a Subsidiary as
an Unrestricted Subsidiary (a "Revocation") unless:

                  (a) no Default shall have occurred and be continuing at the
         time of and after giving effect to such Revocation; and

                  (b) all Liens and Indebtedness of such Unrestricted Subsidiary
         outstanding immediately following such Revocation would, if incurred at
         such time, have been permitted to be incurred for all purposes of this
         Indenture.

                  All Designations and Revocations must be evidenced by Board
Resolutions delivered to the Trustee certifying compliance with the foregoing
provisions.

                  Section 10.22. Designations of Restricted Affiliates.

                  The Company shall not designate any Joint Venture (other than
a newly created Joint Venture in which no Investment has previously been made)
or any of its Subsidiaries as a "Restricted Affiliate" under this Indenture (a
"JV Designation") unless:

                  (a) no Default shall have occurred and be continuing at the
         time of and after giving effect to such JV Designation; and

                  (b) all Liens and Indebtedness of such Joint Venture
         outstanding immediately following such JV Designation would, if
         incurred at such time, have been permitted to be incurred for all
         purposes of this Indenture.

                  Notwithstanding the foregoing, the BECO Joint Venture and the
PEPCO Joint Venture shall initially constitute Restricted Affiliates at the
Issue Date. The Company and the Restricted Subsidiaries shall at all times
maintain a Restricted Affiliate so that it qualifies as a Joint Venture under
clauses (a) and (b) of the definition thereof, unless either (1) the Company is
able to, and does in fact, make an effective JV Revocation under the provisions
set forth below at the time of such event or (2) the Restricted Affiliate ceases
to qualify as a Joint Venture by reason of an Asset Sale by the Company or a
Restricted Subsidiary of all of the Company's or such Restricted Subsidiary's
interest in the Capital Stock of such Restricted Affiliate to any person other
than the Company or a Restricted Subsidiary or any of their respective
Affiliates, which, in the case of this clause (2), shall be deemed an effective
JV Revocation.

                  The Company will not revoke any JV Designation of a Joint
Venture as a Restricted Affiliate (a "JV Revocation") unless:

                  (1) no Default shall have occurred and be continuing at
         the time of or after giving effect to such JV Revocation;

                  (2) except in the case of a Permitted Investment or an
         Investment made pursuant to clause (e) or (f) of the second paragraph
         of Section 10.13 hereof and except in the case in which the Restricted
         Affiliate will become a Restricted Subsidiary, immediately after giving
         effect to such JV Revocation, the Company would be able to incur $1.00
         of Indebtedness under the proviso of clause (A)(X) of Section 10.11
         hereof; and

                  (3) the Company would not be prohibited under the
         Indenture from making an Investment at the time of such JV Revocation
         (assuming the effectiveness of such JV Revocation) in an amount (the
         "JV Revocation Amount") equal to the Fair Market Value of the net
         Investment of the Company or any other Restricted Subsidiary in such
         Restricted Subsidiary on such date.

                  In the event of any such JV Revocation, except in the case in
which the Restricted Affiliate will become a Restricted Subsidiary, the Company
shall be deemed to have made an Investment constituting a Restricted Payment
pursuant to Section 10.13 hereof for all purposes of this Indenture in the JV
Revocation Amount.

                  All JV Designations and JV Revocations must be evidenced by
Board Resolutions delivered to the applicable Trustee certifying compliance with
the foregoing provisions.

                  Section 10.23. Compliance Certificates and Opinions.

                  Upon any application or request by the Company to the Trustee
to take any action under any provision of this Indenture, the Company will
furnish to the Trustee an Officers' Certificate stating that all conditions
precedent, if any, provided for in this Indenture (including any covenants
compliance with which constitutes a condition precedent) relating to the
proposed action have been complied with, and an Opinion of Counsel stating that
in the opinion of such counsel all such conditions precedent, if any, have been
complied with, except that, in the case of any such application or request as to
which the furnishing of such documents, certificates and/or opinions is
specifically required by any provision of this Indenture relating to such
particular application or request, no additional certificate or opinion need be
furnished.

                  Every certificate or opinion with respect to compliance with a
condition or covenant provided for in this Indenture will include:

                     (i) a statement that each individual signing such
         certificate or opinion has read such covenant or condition and the
         definitions herein relating thereto;

                    (ii) a brief statement as to the nature and scope of the
         examination or investigation upon which the statements or opinions
         contained in such certificate or opinion are based;

                   (iii) a statement that, in the opinion of each such
         individual, he has made such examination or investigation as is
         necessary to enable him to express an informed opinion as to whether
         such covenant or condition has been complied with; and

                    (iv) a statement as to whether, in the opinion of each such
         individual, such condition or covenant has been complied with.

                  Section 10.24. Reports.

                  The Company shall, whether or not it has a class of securities
registered under the Exchange Act, furnish without cost to each Holder (in
sufficient quantities for distribution to beneficial holders) and file with the
Trustee and the SEC, (i) within the applicable time period required under the
Exchange Act, after the end of each fiscal year of the Company, the information
required by Form 10-K (or any successor form thereto) under the Exchange Act
with respect to such period, (ii) within the applicable time period required
under the Exchange Act after the end of each of the first three fiscal quarters
of each fiscal year of the Company, the information required by Form 10-Q (or
any successor form thereto) under the Exchange Act with respect to such period
and (iii) any current reports on Form 8-K (or any successor forms) required to
be filed under the Exchange Act.

                           SATISFACTION AND DISCHARGE

                  Section 11.01. Satisfaction and Discharge of Indenture.

                  This Indenture shall cease to be of further effect (except as
to surviving rights or registration of transfer or exchange of Notes herein
expressly provided for) and the Trustee, on written demand of and at the expense
of the Company, shall execute proper instruments acknowledging satisfaction and
discharge of this Indenture, when:

                  (1) either (a) all Notes theretofore authenticated and
         delivered (other than (i) Notes which have been destroyed, lost or
         stolen and which have been replaced or paid as provided in Section 3.06
         hereof and (ii) Notes for whose payment money has theretofore been
         irrevocably deposited or caused to be deposited in trust or segregated
         and held in trust by the Company and thereafter repaid to the Company
         or discharged from such trust, as provided in Section 10.03) have been
         delivered to the Trustee for cancellation; or (b) all such Notes not
         theretofore delivered to the Trustee for cancellation have become due
         and payable and the Company has irrevocably deposited or caused to be
         deposited with the Trustee in trust an amount of money in dollars
         sufficient to pay and discharge the entire Indebtedness on such issue
         of Notes not theretofore delivered to the Trustee for cancellation, for
         the principal of, premium, if any, and interest to the date of such
         deposit or maturity date of redemption; and

                  (2) the Company has paid or caused to be paid all other
         sums payable hereunder by the Company; and

                  (3) the Company has delivered to the Trustee an
         Officers' Certificate and an Opinion of Counsel each stating that all
         conditions precedent herein provided for relating to the satisfaction
         and discharge of this Indenture have been complied with; provided, that
         such Opinion of Counsel may rely, as to matters of fact, upon an
         Officers' Certificate.

Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Company to the Trustee under Sections 4.05 and 6.07 and, if
money shall have been deposited with the Trustee pursuant to subclause (1)(b) of
this Section 11.01, the obligations of the Trustee under Section 11.02 and the
last paragraph of Section 10.03 shall survive.

                  Section 11.02. Application of Trust Money.

                  Subject to the provisions of the last paragraph of Section
10.03, all money deposited with the Trustee pursuant to Section 11.01 shall be
held in trust and applied by it, in accordance with the provisions of the Notes
and this Indenture, to the payment, either directly or through any Paying Agent
(including the Company acting as its own Paying Agent) as the Trustee may
determine, to the persons entitled thereto, of the principal of, premium, if
any, and interest on the Notes for whose payment such money has been deposited
with the Trustee.

                                 ARTICLE TWELVE

                                   REDEMPTION

                  Section 12.01. Notices to the Trustee.

                  If the Company elects to redeem Notes pursuant to Paragraph 3
of the Initial Notes or Paragraph 2 of the Exchange Notes, it shall notify the
Trustee of the Redemption Date and principal amount of Notes to be redeemed.

                  The Company shall notify the Trustee of any redemption at
least 45 days before the Redemption Date by an Officers' Certificate, stating
that such redemption will comply with the provisions hereof and of the Notes.

                  Section 12.02. Selection of Notes To Be Redeemed.

                  In the event that less than all of the Notes are to be
redeemed at any time, selection of such Notes for redemption will be made by the
Trustee in compliance with any applicable requirements of the principal national
securities exchange, if any, on which the Notes are listed or, if the Notes are
not then listed on a national securities exchange (or if the Notes are so listed
but the exchange does not impose requirements with respect to the selection of
debt securities for redemption), on a pro rata basis, by lot or by such method
as the Trustee in its sole discretion shall deem fair and appropriate; provided,
however, that no Notes of a principal amount at maturity of $1,000 or less shall
be redeemed in part.

                  The Trustee shall promptly notify the Company and the
Registrar in writing of the Notes selected for redemption and, in the case of
any Notes selected for partial redemption, the principal amount at maturity
thereof to be redeemed.

                  For all purposes of this Indenture, unless the context
otherwise requires, all provisions relating to redemption of Notes shall relate,
in the case of any Note redeemed or to be redeemed only in part, to the portion
of the principal amount of such Note which has been or is to be redeemed.

                  Section 12.03. Notice of Redemption.

                  Notice of redemption shall be given by first-class mail,
postage prepaid, mailed not less than 30 nor more than 60 days prior to the
Redemption Date, to each Holder of Notes to be redeemed, at the address of such
Holder appearing in the Note register maintained by the Registrar.

                  All notices of redemption shall identify the Notes to be
redeemed and shall state:

                  (a)  the Redemption Date;

                  (b) the Redemption Price and the amount of accrued interest,
         if any, to be paid;

                  (c) that, unless the Company defaults in making the redemption
         payment, interest on Notes called for redemption ceases to accrue on
         and after the Redemption Date, and the only remaining right of the
         Holders of such Notes is to receive payment of the Redemption Price
         plus unpaid interest on the Notes through the Redemption Date, upon
         surrender to the Paying Agent of the Notes redeemed;

                  (d) if any Note is to be redeemed in part, the portion of the
         principal amount at maturity (equal to $1,000 or any integral multiple
         thereof) of such Note to be redeemed and that on and after the
         Redemption Date, upon surrender for cancellation of such Note to the
         Paying Agent, a new Note or Notes in the aggregate principal amount at
         maturity equal to the unredeemed portion thereof will be issued without
         charge to the Noteholder;

                  (e) that Notes called for redemption must be surrendered to
         the Paying Agent to collect the Redemption Price and the name and
         address of the Paying Agent; and

                  (f) the CUSIP or CINS number, if any, relating to such Notes.

                  Notice of redemption of Notes to be redeemed at the election
of the Company shall be given by the Company or, at the Company's written
request, by the Trustee in the name and at the expense of the Company.

                  Section 12.04. Effect of Notice of Redemption.

                  Once notice of redemption is mailed, Notes called for
redemption become due and payable on the Redemption Date and at the Redemption
Price. Upon surrender to the Paying Agent, such Notes called for redemption
shall be paid at the Redemption Price plus accrued interest, if any, to the
Redemption Date, but interest installments whose maturity is on or prior to such
Redemption Date will be payable on the relevant Interest Payment Dates to the
Holders of record at the close of business on the relevant record dates referred
to in the Notes.

                  Section 12.05. Deposit of Redemption Price.

                  On or prior to any Redemption Date, the Company shall deposit
with the Paying Agent an amount of money in same day funds sufficient to pay the
Redemption Price of, and any accrued interest on, all the Notes or portions
thereof which are to be redeemed on that date, other than Notes or portions
thereof called for redemption on that date which have been delivered by the
Company to the Trustee for cancellation.

                  If the Company complies with the preceding paragraph, then,
unless the Company defaults in the payment of such Redemption Price, interest on
the Notes to be redeemed will cease to accrue on and after the applicable
Redemption Date, whether or not such Notes are presented for payment, and the
Holders of such Notes shall have no further rights with respect to such Notes
except for the right to receive the Redemption Price plus unpaid interest on the
Notes through the Redemption Date, upon surrender of such Notes. If any Note
called for redemption shall not be so paid upon surrender thereof for
redemption, the principal, premium, if any, and, to the extent lawful, accrued
interest thereon shall, until paid, bear interest from the Redemption Date at
the rate provided in the Notes.

                  Section 12.06. Notes Redeemed or Purchased in Part.

                  Upon surrender to the Paying Agent of a Note which is to be
redeemed in part, the Company shall execute and the Trustee shall authenticate
and deliver to the Holder of such Note without service charge, a new Note or
Notes, of any authorized denomination as requested by such Holder in aggregate
principal amount equal to, and in exchange for, the unredeemed portion of the
principal of the Note so surrendered that is not redeemed.

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

time of payment is legal tender for payment of public and private debts;
provided, however, that payment of interest may be made at the option of the
Company by check mailed to the address of the person entitled thereto as such
address shall appear on the Note Register.

                  Reference is hereby made to the further provisions of this

                                [REVERSE OF NOTE]

                  1. Indenture. This Note is one of a duly authorized issue of
Notes of the Company designated as its 9.80% Senior Discount Notes due 2008,
Series A (herein called the "Initial Notes"). The Notes are limited (except as
otherwise provided in the Indenture referred to below) in aggregate principal
amount at maturity to $567,000,000, which may be issued under an indenture
(herein called the "Indenture") dated as of February 6, 1998, by and between the
Company and The Chase Manhattan Bank, as trustee (herein called the "Trustee,"
which term includes any successor Trustee under the Indenture), to which
Indenture and all indentures supplemental thereto reference is hereby made for a
statement of the respective rights, limitations of rights, duties, obligations
and immunities thereunder of the Company, the Trustee and the Holders of the
Notes, and of the terms upon which the Notes are, and are to be, authenticated
and delivered. The Notes include the Initial Notes, the Private Exchange Notes
and the Unrestricted Notes (including the Exchange Notes referred to below),
issued in exchange for the Initial Notes pursuant to the Registration Rights
Agreement. The Initial Notes and the Unrestricted Notes are treated as a single
class of securities under the Indenture.

                  All capitalized terms used in this Note which are defined in
the Indenture and not otherwise defined herein shall have the meanings assigned
to them in the Indenture.

                  The terms of the Notes include those stated in the Indenture
and those made part of the Indenture by reference to the Trust Indenture Act of
1939 (15 U.S.C. ss.ss. 77aaa-77bbbb) (the "TIA"), as in effect on the date of
the Indenture. Notwithstanding anything to the contrary herein, the Notes are
subject to all such terms, and Holders of Notes are referred to the Indenture
and the TIA for a statement of such terms.

                  No reference herein to the Indenture and no provisions of this
Note or of the Indenture shall alter or impair the obligation of the Company,
which is absolute and unconditional, to pay the principal of, premium, if any,
and interest on this Note at the times, place, and rate, and in the coin or
currency, herein prescribed.

                  2. Registration Rights. Pursuant to the Registration Rights
Agreement by and among the Company and the Initial Purchasers, the Company will
be obligated to consummate an exchange offer pursuant to which the Holder of
this Note shall have the right to exchange this Note for 9.80% Senior Discount
Notes due 2008, Series B, of the Company (herein called the "Exchange Notes"),
which have been registered under the Securities Act, in like principal amount
and having identical terms as the Notes (other than as set forth in this
paragraph). The Holders of Notes shall be entitled to receive certain additional
interest payments in the event such exchange offer is not consummated and upon
certain other conditions, all pursuant to and in accordance with the terms of
the Registration Rights Agreement.

                  3. Redemption. The Notes will be redeemable, at the option of
the Company, in whole or in part, on or after February 15, 2003 upon not less
than 30 nor more than 60 days' written notice at the redemption prices
(expressed as percentages of principal amount at maturity) set forth below, plus
accrued and unpaid interest thereon, if any, to the applicable redemption date,
if redeemed during the twelve-month period beginning on February 15 of each of
the years indicated below:

                  Year                                        Percentage
                  ----                                        ----------

           2003...........................................     104.900%
           2004...........................................     103.267%
           2005...........................................     101.633%
           2006 and thereafter............................     100.000%

                  Notwithstanding the foregoing, in the event that after the
Issue Date and prior to February 15, 2001 the Company issues, in one or more
Public Equity Offerings yielding gross cash proceeds of not less than $30.0
million, the Company may redeem, at its option, up to a maximum of 35% of the
aggregate principal amount at maturity of Notes from the net proceeds thereof at
a redemption price of 109.80% of the Accreted Value of the Notes; provided that
not less than 65% of the originally issued aggregate principal amount at
maturity of the Notes would remain outstanding immediately after such
redemption. To effect the foregoing redemption, the Company must mail a notice
of redemption not later than 60 days after the consummation of the Public Equity
Offering that resulted in the requisite gross proceeds. As used above, "Public
Equity Offering" means an underwritten public offering of Common Stock of the
Company effected on a primary basis and registered with the Commission under the
Securities Act.

                  4. Offers to Purchase. Sections 10.10 and 10.15 of the
Indenture provide that upon the occurrence of a Change of Control and following
certain Asset Sales, and subject to certain conditions and limitations contained
therein, the Company shall make an offer to purchase all or a portion of the
Notes in accordance with the procedures set forth in the Indenture.

                  5. Defaults and Remedies. If an Event of Default occurs and is
continuing, the principal of all of the Outstanding Notes, plus all accrued and
unpaid interest, if any, to and including the date the Notes are paid, may be
declared due and payable in the manner and with the effect provided in the
Indenture.

                  6. Defeasance. The Indenture contains provisions (which
provisions apply to this Note) for defeasance at any time of (a) the entire
indebtedness of the Company on this Note and (b) certain restrictive covenants
and related Defaults and Events of Default, in each case upon compliance by the
Company with certain conditions set forth therein.

                  7. Amendments and Waivers. The Indenture permits, with certain
exceptions as provided therein, the amendment thereof and the modification of
the rights and obligations of the Company and the rights of the Holders under
the Indenture at any time by the Company and the Trustee with the consent of the
Holders of not less than a majority of Accreted Value of the Notes at the time
Outstanding. The Indenture also contains provisions permitting the Holders of
specified percentages of Accreted Value of the Notes at the time Outstanding, on
behalf of the Holders of all the Notes, to waive compliance by the Company with
certain provisions of this Indenture and certain past Defaults under the
Indenture and this Note and their consequences. Any such consent or waiver by or
on behalf of the Holder of this Note shall be conclusive and binding upon such
Holder and upon all future Holders of this Note and of any Note issued upon the
registration of transfer hereof or in exchange herefor or in lieu hereof whether
or not notation of such consent or waiver is made upon this Note.

                  8. Denominations, Transfer and Exchange. The Notes are
issuable only in registered form without coupons in denominations of $1,000
principal amount at maturity and any integral multiple thereof. As provided in
the Indenture and subject to certain limitations therein set forth, the Notes
are exchangeable for a like aggregate principal amount of Notes of a different
authorized denomination, as requested by the Holder surrendering the same.

                  As provided in the Indenture and subject to certain
limitations therein set forth, the transfer of this Note is registrable on the
Note Register of the Company, upon surrender of this Note for registration of
transfer at the office or agency of the Company maintained for such purpose in
the Borough of Manhattan in The City of New York, State of New York, or at such
other office or agency of the Company as may be maintained for such purpose,
duly endorsed by, or accompanied by a written instrument of transfer in form
satisfactory to the Company and the Registrar duly executed by, the Holder
hereof or his attorney duly authorized in writing, and thereupon one or more new
Notes, of authorized denominations and for the same aggregate principal amount,
will be issued to the designated transferee or transferees.

                  No service charge shall be made for any registration of
transfer or exchange or redemption of Notes, but the Company may require payment
of a sum sufficient to cover any tax or other governmental charge payable in
connection therewith.

                  9. Persons Deemed Owners. Prior to and at the time of due
presentment of this Note for registration of transfer, the Company, the Trustee
and any agent of the Company or the Trustee may treat the person in whose name
this Note is registered as the owner hereof for all purposes, whether or not
this Note shall be overdue, and neither the Company, the Trustee nor any agent
shall be affected by notice to the contrary.

                  10. GOVERNING LAW. THE INDENTURE AND THIS NOTE SHALL BE
GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK
WITHOUT GIVING EFFECT TO PRINCIPLES OF CONFLICTS OF LAW.

                  The Company will furnish to any Holder of a Note upon written
request and without charge a copy of this Indenture. Requests may be made to:

                  RCN CORPORATION, a corporation incorporated under the laws of
the State of Delaware (herein called the "Company," which term includes any

agency of the Company referred to below, and to pay interest thereon on February
15 and August 15 (each an "Interest Payment Date"), of each year, commencing on
August 15, 2003, accruing from February 15, 2003 or from the most recent
Interest Payment Date to which interest has been paid or duly provided for, at
the rate of 9.80% per annum, until the principal hereof is paid or duly provided
for. Interest shall be computed on the basis of a 360-day year of twelve 30-day
months.

                  The interest so payable, and punctually paid or duly provided
for, on any Interest Payment Date will, as provided in the Indenture referred to

lawful, shall forthwith cease to be payable to the Holder on such Regular Record
Date, and may be paid to the person in whose name this Note (or one or more

manner not inconsistent with the requirements of any securities exchange on
which the Notes may be listed, and upon such notice as may be required by such
exchange, all as more fully provided in the Indenture.

                  Payment of the principal of, premium, if any, and interest on
this Note will be made at the office or agency of the Company maintained for
that purpose in the Borough of Manhattan in The City of New York, State of New
York, or at such other office or agency of the Company as may be maintained for
such purpose, 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;
provided, however, that payment of interest may be made at the option of the
Company by check mailed to the address of the person entitled thereto as such
address shall appear on the Note Register.

                  Reference is hereby made to the further provisions of this
Note set forth on the reverse hereof.

                  Unless the certificate of authentication hereon has been duly
executed by the Trustee referred to on the reverse hereof by manual signature,

                                [REVERSE OF NOTE]

                  1. Indenture. This Note is one of a duly authorized issue of
Notes of the Company designated as its 9.80% Senior Discount Notes due 2008,
Series B (herein called the "Initial Notes"). The Notes are limited (except as
otherwise provided in the Indenture referred to below) in aggregate principal
amount at maturity to $567,000,000, which may be issued under an indenture
(herein called the "Indenture") dated as of February 6, 1998, by and between the
Company and The Chase Manhattan Bank, as trustee (herein called the "Trustee,"
which term includes any successor Trustee under the Indenture), to which
Indenture and all indentures supplemental thereto reference is hereby made for a
statement of the respective rights, limitations of rights, duties, obligations
and immunities thereunder of the Company, the Trustee, and the Holders of the
Notes, and of the terms upon which the Notes are, and are to be, authenticated
and delivered. The Notes include the Initial Notes, the Private Exchange Notes
and the Unrestricted Notes (including the Exchange Notes), issued in exchange
for the Initial Notes pursuant to the Registration Rights Agreement. The Initial
Notes and the Unrestricted Notes are treated as a single class of securities
under the Indenture.

                  All capitalized terms used in this Note which are defined in
the Indenture and not otherwise defined herein shall have the meanings assigned
to them in the Indenture.

                  The terms of the Notes include those stated in the Indenture
and those made part of the Indenture by reference to the Trust Indenture Act of
1939 (15 U.S.C. ss.ss. 77aaa-77bbb) (the "TIA"), as in effect on the date of the
Indenture. Notwithstanding anything to the contrary herein, the Notes are
subject to all such terms, and Holders of Notes are referred to the Indenture
and the TIA for a statement of such terms.

                  No reference herein to the Indenture and no provisions of this
Note or of the Indenture shall alter or impair the obligation of the Company,
which is absolute and unconditional, to pay the principal of, premium, if any,
and interest on this Note at the times, place, and rate, and in the coin or
currency, herein prescribed.

                  2. Redemption. The Notes will be redeemable, at the option of
the Company, in whole or in part, on or after February 15, 2003 upon not less
than 30 nor more than 60 days' written notice at the redemption prices
(expressed as percentages of principal amount at maturity) set forth below, plus
accrued and unpaid interest thereon, if any, to the applicable redemption date,
if redeemed during the twelve-month period beginning on February 15 of each of
the years indicated below:

            Year                                                   Percentage
            ----                                                   ----------

    2003........................................................     104.900%
    2004........................................................     103.267%
    2005........................................................     101.633%
    2006 and thereafter.........................................     100.000%

                  Notwithstanding the foregoing, in the event that after the
Issue Date and prior to February 15, 2001 the Company issues, in one or more
Public Equity Offerings yielding gross proceeds of not less than $30.0 million,
the Company may redeem, at its option, up to a maximum of 35% of the aggregate
principal amount at maturity of the Notes originally issued from the net
proceeds thereof at a redemption price of 109.80% of the Accreted Value of the
Notes provided that not less than 65% of the originally issued aggregate
principal amount at maturity of the Notes would remain outstanding immediately
after such redemption. To effect the foregoing redemption, the Company must mail
a notice of redemption not later than 60 days after the consummation of the
Public Equity Offering that resulted in the requisite gross proceeds. As used
above, "Public Equity Offering" means an underwritten public offering of Common
Stock of the Company effected on a primary basis and registered with the
Commission under the Securities Act.

                  3. Offers to Purchase. Sections 10.10 and 10.15 of the
Indenture provide that upon the occurrence of a Change of Control and following
certain Asset Sales, and subject to certain conditions and limitations contained
therein, the Company shall make an offer to purchase all or a portion of the
Notes in accordance with the procedures set forth in the Indenture.

                  4. Defaults and Remedies. If an Event of Default occurs and is
continuing, the principal of all of the Outstanding Notes, plus all accrued and
unpaid interest, if any, to and including the date the Notes are paid, may be
declared due and payable in the manner and with the effect provided in the
Indenture.

                  5. Defeasance. The Indenture contains provisions (which
provisions apply to this Note) for defeasance at any time of (a) the entire
indebtedness of the Company on this Note and (b) certain restrictive covenants
and related Defaults and Events of Default, in each case upon compliance by the
Company with certain conditions set forth therein.

                  6. Amendments and Waivers. The Indenture permits, with certain
exceptions as provided therein, the amendment thereof and the modification of
the rights and obligations of the Company and the rights of the Holders under
the Indenture at any time by the Company and the Trustee with the consent of the
Holders of not less than a majority of Accreted Value of the Notes at the time
Outstanding. The Indenture also contains provisions permitting the Holders of
specified percentages of Accreted Value of the Notes at the time Outstanding, on
behalf of the Holders of all the Notes, to waive compliance by the Company with
certain provisions of the Indenture and certain past Defaults under the
Indenture and this Note and their consequences. Any such consent or waiver by or
on behalf of the Holder of this Note shall be conclusive and binding upon such
Holder and upon all future Holders of this Note and of any Note issued upon the
registration of transfer hereof or in exchange herefor or in lieu hereof whether
or not notation of such consent or waiver is made upon this Note.

                  7. Denominations, Transfer and Exchange. The Notes are
issuable only in registered form without coupons in denominations of $1,000
principal amount at maturity and any integral multiple thereof. As provided in
the Indenture and subject to certain limitations therein set forth, the Notes
are exchangeable for a like aggregate principal amount of Notes of a different
authorized denomination, as requested by the Holder surrendering the same.

                  As provided in the Indenture and subject to certain
limitations therein set forth, the transfer of this Note is registrable on the
Note Register of the Company, upon surrender of this Note for registration of
transfer at the office or agency of the Company maintained for such purpose in
the Borough of Manhattan in The City of New York, State of New York, or at such
other office or agency of the Company as may be maintained for such purpose,
duly endorsed by, or accompanied by a written instrument of transfer in form
satisfactory to the Company and the Registrar duly executed by, the Holder
hereof or his attorney duly authorized in writing, and thereupon one or more new
Notes, of authorized denominations and for the same aggregate principal amount,
will be issued to the designated transferee or transferees.

                  No service charge shall be made for any registration of
transfer or exchange or redemption of Notes, but the Company may require payment
of a sum sufficient to cover any tax or other governmental charge payable in
connection therewith.

                  8. Persons Deemed Owners. Prior to and at the time of due
presentment of this Note for registration of transfer, the Company, the Trustee
and any agent of the Company or the Trustee may treat the person in whose name
this Note is registered as the owner hereof for all purposes, whether or not
this Note shall be overdue, and neither the Company, the Trustee nor any agent
shall be affected by notice to the contrary.

                  9. GOVERNING LAW. THE INDENTURE AND THIS NOTE SHALL BE
GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK
WITHOUT GIVING EFFECT TO PRINCIPLES OF CONFLICTS OF LAW.

request and without charge a copy of the Indenture. Requests may be made to: RCN

RCN Corporation
105 Carnegie Center
Princeton, NJ  08540

Ladies and Gentlemen:

                  In connection with our proposed purchase of $567,000,000
aggregate principal amount of the 9.80% Senior Discount Notes due 2008 (the
"Notes") of RCN Corporation (the "Company"), we confirm that:

                           1. We understand that the Notes have not been
         registered under the Securities Act of 1933, as amended (the
         "Securities Act"), and, unless so registered, may not be sold except as
         permitted in the following sentence. We agree on our own behalf and on
         behalf of any investor account for which we are purchasing Notes to
         offer, sell or otherwise transfer such Notes prior to (x) the date
         which is two years (or such shorter period of time as permitted by Rule
         144 under the Securities Act) after the later of the date of original
         issue of the Notes and (y) such later date, if any, as may be required
         by any subsequent change in applicable law (the "Resale Restriction
         Termination Date") only (a) to the Company, (b) pursuant to a
         registration statement which has been declared effective under the
         Securities Act, (c) so long as the Notes are eligible for resale
         pursuant to Rule 144A under the Securities Act, to a person we
         reasonably believe is a "qualified institutional buyer" under Rule 144A
         (a "QIB") that purchases for its own account or for the account of a
         QIB and to whom notice is given that the transfer is being made in
         reliance on Rule 144A, (d) pursuant to offers and sales that occur
         outside the United States to "foreign purchasers" (as defined below) in
         offshore transactions meeting the requirements of Rule 904 of
         Regulation S under the Securities Act, (e) to an institutional
         "accredited investor" within the meaning of subparagraph (a)(1), (2),
         (3) or (7) of Rule 501 under the Securities Act (an "Accredited
         Investor") that is purchasing for its own account or for the account of
         such an institutional "accredited investor," or (f) pursuant to any
         other available exemption from the registration requirements of the
         Securities Act, subject, in each of the foregoing cases, to any
         requirement of law that the disposition of our property or the property
         of such investor account or accounts be at all times within our or
         their control and to compliance with any applicable state securities
         laws. The foregoing restrictions on resale will not apply subsequent to
         the Resale Restriction Termination Date. If any resale or other
         transfer of the Notes is proposed to be made pursuant to clause (c)
         above prior to the Resale Restriction Termination Date, the transferor
         shall deliver a letter from the transferee substantially in the form of
         this letter to the Trustee, which shall provide, among other things,
         that the transferee is an Accredited Investor within the meaning of
         subparagraph (a)(1), (2), (3) or (7) of Rule 501 under the Securities
         Act and that it is acquiring such Notes for investment purposes and not
         for distribution in violation of the Securities Act. Each purchaser
         acknowledges that the Company, the Trustee and the Transfer Agent and
         Registrar reserve the right prior to any offer, sale or other transfer
         prior to the Resale Restriction Termination Date of the Notes pursuant
         to clause (d), (e) or (f) above to require the delivery of an opinion
         of counsel, certification and/or other information satisfactory to the
         Company and the Trustee.

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

                           3. We are acquiring the Notes purchased by us
         for our own account or for one or more accounts as to each of which we
         exercise sole investment discretion and we and any such account are (a)
         a QIB, aware that the sale is being made in reliance on Rule 144A under
         the Securities Act, (b) an Accredited Investor, or (c) a person other
         than a U.S. person ("foreign purchasers"), which term shall include
         dealers or other professional fiduciaries in the United States acting
         on a discretionary basis for foreign beneficial owners (other than an
         estate or trust) in offshore transactions meeting the requirements of
         Rules 903 and 904 of Regulation S under the Securities Act.

                           4. We have received a copy of the Offering
         Memorandum and acknowledge that we have had access to such financial
         and other information, and have been afforded the opportunity to ask
         such questions of representatives of the Company and receive answers
         thereto, as we deem necessary in order to verify the information
         contained in the Offering Memorandum.

                           5. We are not purchasing the Notes for or on
         behalf of, and will not transfer the Notes to, any pension or welfare
         plan (as defined in Section 3 of ERISA), except as may be permitted
         under ERISA and as described under "Notice to Investors" in the
         Offering Memorandum.

                           6. In the event that we purchase any Notes,
         we will acquire Notes having an outstanding principal amount of at
         least $250,000 for our own account and $250,000 for each account for
         which we are acting.

                  We understand that the Trustee and the Transfer Agent will not
be required to accept for registration of transfer any Notes acquired by us,
except upon presentation of evidence satisfactory to the Company and the Trustee
that the foregoing restrictions on transfer have been complied with. We further
understand that the Notes purchased by us will be in the form of definitive
physical certificates and that such certificates will bear a legend reflecting
the substance of this paragraph. We further agree to provide to any person
acquiring any of the Notes from us a notice advising such person that transfers
of such Notes are restricted as stated herein and that certificates representing
such Notes will bear a legend to that effect.

                  We represent that you, the Company, the Trustee and others are
entitled to rely upon the truth and accuracy of our acknowledgments,
representations and agreements set forth herein, and we agree to notify you
promptly in writing if any of our acknowledgments, representations or agreements
herein cease to be accurate and complete. You are also irrevocably authorized to
produce this letter or a copy hereof to any interested party in any
administrative or legal proceeding or official inquiry with respect to the
matters covered hereby.

                  We represent to you that we have full power to make the
foregoing acknowledgments, representations and agreements on our own behalf and
on behalf of any investor account for which we are acting as fiduciary agent.

                  As used herein, the terms "offshore transaction," "United
States" and "U.S. person" have the respective meanings given to them in
Regulation S under the Securities Act.

                  THIS LETTER SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE
WITH, THE LAWS OF THE STATE OF NEW YORK.

                                                          Very truly yours,


                                                          (Name of Purchaser)

         or all of the Private Exchange Notes, as the case may be, on an
         appropriate form under Rule 415 under the Securities Act, or any
         similar rule that may be adopted by the SEC, and all amendments and
         supplements to such registration statement, including post-effective
         amendments, in each case including the Prospectus contained therein,
         all exhibits thereto and all material incorporated by reference
         therein.

                  "Target Consummation Date" see Section 2(a).

                  "Target Effectiveness Date" see Section 2(a).

                  "TIA" shall have the meaning set forth in Section 3(k) hereof.

                  "Transfer Restricted Notes" means each Note until (i) the date
         on which such has been exchanged by a person other than a broker-dealer
         for an Exchange Note in the Exchange Offer, (ii) following the exchange
         by a broker-dealer in the Exchange Offer of a Note for an Exchange
         Note, the date on which such Exchange Note is sold to a purchaser who
         receives from such broker-dealer on or prior to the date of such sale a
         copy of the prospectus contained in the Exchange Offer Registration
         Statement, (iii) the date on which such Note has been effectively
         registered under the Securities Act and disposed of in accordance with
         the Shelf Registration Statement, (iv) the date on which such Note is
         distributed to the public pursuant to Rule 144(k) under the Securities
         Act (or any similar provision then in force, but not Rule 144A under
         the Securities Act), (v) such Note shall have been otherwise
         transferred by the holder thereof and a new Note not bearing a legend
         restricting further transfer shall have been delivered by the Company
         and subsequent disposition of such Note shall not require registration
         or qualification under the Securities Act or any similar state law then
         in force or (vi) such Note ceases to be outstanding.

                  "Trustee" shall mean the trustee with respect to the Notes
         under the Indenture.

                  2.  Registration Under the Securities Act.

                  (a) Exchange Offer. The Company shall, for the benefit of the
Holders, at the Company's cost, (i) unless the Exchange Offer would not be
permitted by applicable law or SEC policy, file with the SEC within 45 days
after the Issue Date an Exchange Offer Registration Statement on an appropriate
form under the Securities Act covering the offer by the Company to the Holders
to exchange all of the Transfer Restricted Notes (other than Private Exchange
Notes (as defined below)) for a like principal amount of Exchange Notes, (ii)
unless the Exchange Offer would not be permitted by applicable law or SEC
policy, use its best efforts to have such Exchange Offer Registration Statement
declared effective under the Securities Act by the SEC not later than 90 days
after the Issue Date (the "Target Effectiveness Date"), (iii) have such
Registration Statement remain effective until the closing of the Exchange Offer
and (iv) unless the Exchange Offer would not be permitted by applicable law or
SEC policy, commence the Exchange Offer and use its best efforts to issue, on or
prior to the 135th day after the Issue Date (the "Target Consummation Date"),
Exchange Notes in exchange for all Notes tendered prior thereto in the Exchange
Offer. Upon the effectiveness of the Exchange Offer Registration Statement, the
Company shall promptly commence the Exchange Offer, it being the objective of
such Exchange Offer to enable each Holder eligible and electing to exchange
Transfer Restricted Notes for Exchange Notes (assuming that such Holder is not
an affiliate of the Company within the meaning of Rule 405 under the Securities
Act and is not a broker-dealer tendering Transfer Restricted Notes acquired
directly from the Company for its own account, acquires the Exchange Notes in
the ordinary course of such Holder's business and has no arrangements or
understandings with any Person to participate in the Exchange Offer for the
purpose of distributing (within the meaning of the Securities Act) the Exchange
Notes) and to transfer such Exchange Notes from and after their receipt without
any limitations or restrictions under the Securities Act and under state
securities or blue sky laws.

                  In connection with the Exchange Offer, the Company shall:

                   (i)  mail to each Holder a copy of the Prospectus
         forming part of the Exchange Offer Registration Statement, together
         with an appropriate letter of transmittal and related documents;

                  (ii)  keep the Exchange Offer open for acceptance for a
         period of not less than 20 Business Days after the date notice thereof
         is mailed to the Holders (or longer if required by applicable law)
         (such period referred to herein as the "Exchange Period");

                  (iii) utilize the services of the Depositary for the Exchange
         Offer;

                  (iv)  permit Holders to withdraw tendered Notes at any
         time prior to the close of business, New York time, on the last
         Business Day of the Exchange Period, by sending to the institution
         specified in the notice, a telegram, telex, facsimile transmission or
         letter setting forth the name of such Holder, the principal amount of
         Notes delivered for exchange, and a statement that such Holder is
         withdrawing his election to have such Notes exchanged; and

                   (v)  otherwise comply in all material respects with all
         applicable laws relating to the Exchange Offer.

                  If, prior to consummation of the Exchange Offer the Initial
Purchasers hold any Notes acquired by them and having the status of an unsold
allotment in the initial distribution, the Company upon the request of any
Initial Purchaser shall, simultaneously with the delivery of the Exchange Notes
in the Exchange Offer, issue and deliver to such Initial Purchaser in exchange
(the "Private Exchange") for the Notes held by such Initial Purchaser, a like
principal amount of debt securities of the Company that are identical (except
that such securities shall bear appropriate transfer restrictions) to the
Exchange Notes (the "Private Exchange Notes").

                  The Exchange Notes and the Private Exchange Notes shall be
issued under (i) the Indenture or (ii) an indenture identical to all material
respects to the Indenture and which, in either case, has been qualified under
the TIA or is exempt from such qualification and shall provide that the Exchange
Notes shall not be subject to the transfer restrictions set forth in the
Indenture. The Indenture or such indenture shall provide that the Exchange
Notes, the Private Exchange Notes and the Notes shall vote and consent together
on all matters as one class and that none of the Exchange Notes, the Private
Exchange Notes or the Notes will have the right to vote or consent as a separate
class on any matter. The Private Exchange Notes shall be of the same series as
and the Company shall use all commercially reasonable efforts to have the
Private Exchange Notes bear the same CUSIP number as the Exchange Notes. The
Company shall not have any liability under this Agreement solely as a result of
such Private Exchange Notes not bearing the same CUSIP number as the Exchange
Notes.

                  The Exchange Offer and the Private Exchange shall not be
subject to any conditions, other than that (i) the Exchange Offer or Private
Exchange, as the case may be, does not violate applicable law or any applicable
interpretation of the staff of the SEC (ii) no action or proceeding shall have
been instituted or threatened in any court or by any governmental agency which
might materially impair the ability of the Company to proceed with the Exchange
Offer or the Private Exchange, and no material adverse development shall have
occurred in any existing action or proceeding with respect to the Company and
(iii) all governmental approvals shall have been obtained, which approvals the
Company deems necessary for the consummation of the Exchange Offer or Private
Exchange. As soon as practicable after the close of the Exchange Offer and/or
the Private Exchange, as the case may be, the Company shall:

                   (i)  accept for exchange all Transfer Restricted Notes
         or portions thereof properly tendered and not validly withdrawn
         pursuant to the Exchange Offer in accordance with the terms of the
         Exchange Offer Registration Statement and the letter of transmittal
         which is an exhibit thereto;

                  (ii)  accept for exchange all Notes properly tendered
         pursuant to the Private Exchange; and

                 (iii)  deliver, or cause to be delivered, to the Trustee
         for cancellation all Transfer Restricted Notes or portions thereof so
         accepted for exchange by the Company, and issue, and cause the Trustee
         under the Indenture to promptly authenticate and deliver to each
         Holder, a new Exchange Note or Private Exchange Note, as the case may
         be, equal in principal amount to the principal amount of the Transfer
         Restricted Notes surrendered by such Holder and accepted for exchange.

                  To the extent not prohibited by any law or applicable
interpretation of the staff of the SEC, the Company shall use its best efforts
to complete the Exchange Offer as provided above, and shall comply with the
applicable requirements of the Securities Act, the Exchange Act and other
applicable laws in connection with the Exchange Offer. The Exchange Offer shall
not be subject to any conditions, other than those set forth in the immediately
preceding paragraph. Each Holder of Transfer Restricted Notes who wishes to
exchange such Transfer Restricted Notes for Exchange Notes in the Exchange Offer
will be required to make certain customary representations in connection
therewith, including representations that such Holder is not an affiliate of the
Company within the meaning of Rule 405 under the Securities Act, that any
Exchange Notes to be received by it will be acquired in the ordinary course of
business and that at the time of the commencement of the Exchange Offer it has
no arrangement with any Person to participate in the distribution (within the
meaning of the Securities Act) of the Exchange Notes. The Company shall inform
the Initial Purchasers of the names and addresses of the Holders to whom the
Exchange Offer is made, and the Initial Purchasers shall have the right to
contact such Holders and otherwise facilitate the tender of Transfer Restricted
Notes in the Exchange Offer.

                  Upon consummation of the Exchange Offer in accordance with
this Section 2(a), the provisions of this Agreement shall continue to apply,
mutatis mutandis, solely with respect to Transfer Restricted Notes that are
Private Exchange Notes and Exchange Notes held by Participating Broker-Dealers,
and the Company shall have no further obligation to register Transfer Restricted
Notes (other than Private Exchange Notes) pursuant to Section 2(b) hereof.

                  (b) Shelf Registration. If (i) the Company is not permitted to
file the Exchange Offer Registration Statement or to consummate the Exchange
Offer because the Exchange Offer is not permitted by applicable law or SEC
policy, (ii) the Exchange Offer is not for any other reason consummated by the
Target Consummation Date, (iii) any holder of Notes notifies the Company within
a specified time period that (a) due to a change in law or policy, in the
opinion of counsel, it is not entitled to participate in the Exchange Offer, (b)
due to a change in law or policy, in the opinion of counsel, it may not resell
the Exchange Notes acquired by it in the Exchange Offer to the public without
delivering a prospectus and (x) the prospectus contained in the Exchange Offer
Registration Statement is not appropriate or available for such resales by such
holder and (y) such prospectus is not promptly amended or modified in order to
be suitable for use in connection with such resales for such holder and all
similarly situated holders or (c) it is a broker-dealer and owns Notes acquired
directly from the Company or an affiliate of the Company, (iv) the holders of a
majority of the Notes may not resell the Exchange Notes acquired by them in the
Exchange Offer to the public without restriction under the Securities Act and
without restriction under applicable blue sky or state securities laws or (v)
the Exchange Offer shall not have been consummated within 135 days after the
Issue Date (the date of any of (i)-(v), the "Shelf Registration Event Date"),
then the Company shall, at its cost, use its best efforts to cause to be filed a
Shelf Registration Statement prior to the later of (A) 30 days after the Shelf
Registration Event Date or (B) 165 days after the Issue Date and use its best
efforts to cause the Shelf Registration Statement to be declared effective by
the SEC on or prior to 60 days after such obligation arises. Each Holder as to
which any Shelf Registration is being effected agrees to furnish to the Company
all information with respect to such Holder necessary to make any information
previously furnished to the Company by such Holder not materially misleading.

                  The Company agrees to use its best efforts to keep the Shelf
Registration Statement continuously effective for a period of two years from the
effective date of the Shelf Registration Statement (subject to extension
pursuant to the last paragraph of Section 3 hereof) (or such shorter period that
will terminate when all of the Transfer Restricted Notes covered by such Shelf
Registration Statement have been sold pursuant thereto) or cease to be
outstanding (the "Effectiveness Period"); provided, however, that the
Effectiveness Period in respect of the Shelf Registration Statement shall be
extended to the extent required to permit dealers to comply with the applicable
prospectus delivery requirements of Rule 174 under the Securities Act and as
otherwise provided herein. The Company shall not permit any securities other
than Transfer Restricted Notes to be included in the Shelf Registration. The
Company further agrees, if necessary, to supplement or amend the Shelf
Registration Statement, if required by the rules, regulations or instructions
applicable to the registration form used by the Company for such Shelf
Registration Statement or by the Securities Act or by any other rules and
regulations thereunder for shelf registrations, and the Company agrees to
furnish to the Holders of Transfer Restricted Notes copies of any such
supplement or amendment promptly after its being used or filed with the SEC.

                  (c) Expenses. The Company shall pay all Registration Expenses
in connection with the registration pursuant to Section 2(a) or 2(b) hereof and
the reasonable fees and expenses of one counsel, if any, designated in writing
by the Majority Holders to act as counsel for the Holders of the Transfer
Restricted Notes in connection with a Shelf Registration Statement. Except as
provided in the preceding sentence, each Holder shall pay all expenses of its
counsel, underwriting discounts and commissions and transfer taxes, if any,
relating to the sale or disposition of such Holder's Transfer Restricted Notes
pursuant to the Shelf Registration Statement.

                  (d) Effective Registration Statement. An Exchange Offer
Registration Statement pursuant to Section 2(a) hereof or a Shelf Registration
Statement pursuant to Section 2(b) hereof will not be deemed to have become
effective unless it has been declared effective by the SEC; provided, however,
that if, after it has been declared effective, the offering of Transfer
Restricted Notes pursuant to a Shelf Registration Statement is interfered with
by any stop order, injunction or other order or requirement of the SEC or any
other governmental agency or court, such Registration Statement will be deemed
not to have been effective during the period of such interference, until the
offering of Transfer Restricted Notes may legally resume. The Company will be
deemed not to have used its best efforts to cause the Exchange Offer
Registration Statement or the Shelf Registration Statement, as the case may be,
to become, or to remain, effective during the requisite period if it voluntarily
takes any action that would result in any such Registration Statement not being
declared effective or in the Holders of Transfer Restricted Notes covered
thereby not being able to exchange or offer and sell such Transfer Restricted
Notes during that period, unless such action is required by applicable law and
except as otherwise provided in the second paragraph of Section 2(e) below.

                  (e) Additional Interest. In the event that (i) the applicable
Registration Statement is not filed with the SEC on or prior to the date
specified herein for such filing, (ii) the applicable Registration Statement is
not declared effective on or prior to the date specified herein for such
effectiveness after such obligation arises (the "Effectiveness Target Date"),
(iii) if the Exchange Offer is required to be consummated hereunder, the Company
fails to consummate the Exchange Offer by the Target Consummation Date with
respect to the Exchange Offer Registration Statement or (iv) the applicable
Registration Statement is filed and declared effective during the period
effectiveness is required by Section 2(e) and 3(a) but shall thereafter cease to
be effective or usable without being succeeded immediately by an additional
Registration Statement covering the Transfer Restricted Notes which has been
filed and declared effective (each such event referred to in clauses (i) through
(iv), a "Registration Default"), then the interest rate on the Transfer
Restricted Notes as to which such Registration Default relates will increase
("Additional Interest"), with respect to the each 90-day period while a
Registration Default is continuing immediately following the occurrence of such
Registration Default in an amount equal to 0.25% per annum of the principal
amount of the Notes until all Registration Defaults have been cured, subject to
a maximum amount of 1.00% of the principal amount of the Notes. Upon (w) the
filing of the applicable Registration Statement (in the case of clause (i) of
the preceding sentence), (x) the effectiveness of the applicable Registration
Statement (in the case of clause (ii) of the preceding sentence), (y) the
issuance of Exchange Notes in exchange for all Notes properly tendered and not
withdrawn in the Exchange Offer (in the case of clause (iii) of the preceding
sentence) or (z) the effectiveness of the applicable Registration Statement
which has ceased to be effective (in the case of clause (iv) of the preceding
sentence, Additional Interest as a result of the Registration Default described
in such clause shall cease to accrue (but any accrued amount shall be payable)
and the interest rate on the applicable Notes will revert to the original rate
if no other Registration Default has occurred and is continuing. Additional
Interest shall be computed based on the actual number of days elapsed during
which any such Registration Defaults exist.

                  The Company shall notify the Trustee within three Business
Days after each and every date on which an event occurs in respect of which
Additional Interest is required to be paid (an "Event Date"). Additional
Interest shall be paid by depositing with the Trustee, in trust, for the benefit
of the Holders of Transfer Restricted Notes, on or before the immediately
following February 15 or August 15, immediately available funds in sums
sufficient to pay the Additional Interest then due. The Additional Interest due
shall be payable on each February 15 and August 15 to the record Holder of Notes
entitled to receive the interest payment to be paid on such date as set forth in
the Indenture. Each obligation to pay Additional Interest shall be deemed to
accrue from and including the day following the applicable Event Date.

                  3. Registration Procedures. In connection with the obligations
of the Company with respect to the Registration Statements pursuant to Sections
2(a) and 2(b) hereof, the Company shall:

                    (a)  prepare and file with the SEC a Registration
         Statement or Registration Statements as prescribed by Sections 2(a) and
         2(b) hereof within the relevant time period specified in Section 2
         hereof on the appropriate form under the Securities Act, which form (i)
         shall be selected by the Company, (ii) shall, in the case of a Shelf
         Registration, be available for the sale of the Transfer Restricted
         Notes by the selling Holders thereof and (iii) shall comply as to form
         in all material respects with the requirements of the applicable form
         and include all financial statements required by the SEC to be filed
         therewith; and use their best efforts to cause such Registration
         Statement to become effective and remain effective in accordance with
         Section 2 hereof. The Company shall not file any Registration Statement
         or Prospectus or any amendments or supplements thereto in respect of
         which the Holders must provide information for inclusion therein
         without the Holders being afforded an opportunity to review such
         documentation a reasonable time prior to the filing of such document if
         the Majority Holders or such Participating Broker-Dealer, as the case
         may be, their counsel or the managing underwriters, if any, shall
         reasonably object;

                    (b)  prepare and file with the SEC such amendments and
         post-effective amendments to each Registration Statement as may be
         necessary to keep such Registration Statement effective for the
         Effectiveness Period or the Applicable Period, as the case may be; and
         cause each Prospectus to be supplemented by any required prospectus
         supplement and as so supplemented to be filed pursuant to Rule 424 (or
         any similar provision then in force) under the Securities Act, and
         comply with the provisions of the Securities Act, the Exchange Act and
         the rules and regulations promulgated thereunder applicable to it with
         respect to the disposition of all securities covered by each
         Registration Statement during the Effectiveness Period or the
         Applicable Period, as the case may be, in accordance with the intended
         method or methods of distribution by the selling Holders thereof
         described in this Agreement (including sales by any Participating
         Broker-Dealer);

                    (c)  in the case of a Shelf Registration, (i) notify
         each Holder of Transfer Restricted Notes, at least three Business Days
         prior to filing, that a Shelf Registration Statement with respect to
         the Transfer Restricted Notes is being filed and advising such Holder
         that the distribution of Transfer Restricted Notes will be made in
         accordance with the method selected by the Majority Holders; and (ii)
         furnish to each Holder of Transfer Restricted Notes, without charge, as
         many copies of each Prospectus, and any amendment or supplement thereto
         and such other documents as such Holder may reasonably request, in
         order to facilitate the disposition of the Transfer Restricted Notes;
         and (iii) subject to the last paragraph of Section 3 hereof, hereby
         consent to the use of the Prospectus or any amendment or supplement
         thereto by each of the selling Holders of Transfer Restricted Notes in
         connection with the offering and sale of the Transfer Restricted Notes
         covered by such Prospectus or any amendment or supplement thereto
         subject to the limitations on the use thereof provided in Sections 2(b)
         and 2(c);

                    (d)  in the case of a Shelf Registration, use its best
         efforts to register or qualify, as may be required by applicable law,
         the Transfer Restricted Notes under all applicable state securities or
         "blue sky" laws of such jurisdictions by the time the applicable
         Registration Statement is declared effective by the SEC as any Holder
         of Transfer Restricted Notes covered by a Registration Statement shall
         reasonably request in advance of such date of effectiveness, and do any
         and all other acts and things which may be reasonably necessary or
         advisable to enable such Holder to consummate the disposition in each
         such jurisdiction of such Transfer Restricted Notes owned by such
         Holder; provided, however, that the Company shall not be required to
         (i) qualify as a foreign corporation or as a broker or dealer in
         securities in any jurisdiction where it would not otherwise be required
         to qualify but for this Section 3(d), (ii) file any general consent to
         service of process or (iii) subject itself to taxation in any such
         jurisdiction if it is not so subject;

                    (e)  in the case of (1) a Shelf Registration or (2)
         Participating Broker-Dealers who have notified the Company that they
         will be utilizing the Prospectus contained in the Exchange Offer
         Registration Statement as provided in Section 3(t) hereof, notify each
         Holder of Transfer Restricted Notes, or such Participating
         Broker-Dealers, as the case may be, their counsel, if any, promptly and
         confirm such notice in writing (i) when a Registration Statement has
         become effective and when any post-effective amendments and supplements
         thereto become effective, (ii) of any request by the SEC or any state
         securities authority for amendments and supplements to a Registration
         Statement or Prospectus or for additional information after the
         Registration Statement has become effective, (iii) of the issuance by
         the SEC or any state securities authority of any stop order suspending
         the effectiveness of a Registration Statement or the initiation of any
         proceedings for that purpose, (iv) if the Company receives any
         notification with respect to the suspension of the qualification of the
         Transfer Restricted Notes or the Exchange Notes to be sold by any
         Participating Broker-Dealer for offer or sale in any jurisdiction or
         the initiation of any proceeding for such purpose, (v) of the happening
         of any event or the failure of any event to occur or the discovery of
         any facts or otherwise, during the period a Shelf Registration
         Statement is effective which makes any statement made in such
         Registration Statement or the related Prospectus untrue in any material
         respect or which causes such Registration Statement or Prospectus to
         omit to state a material fact necessary to make the statements therein,
         in the light of the circumstances under which they were made, not
         misleading and (vi) the Company's reasonable determination that a
         post-effective amendment to the Registration Statement would be
         appropriate;

                    (f)  make every reasonable effort to obtain the
         withdrawal of any order suspending the effectiveness of a Registration
         Statement as soon as practicable;

                    (g)  in the case of a Shelf Registration, furnish to
         each Holder of Transfer Restricted Notes, without charge, at least one
         conformed copy of each Registration Statement relating to such Shelf
         Registration and any post-effective amendment thereto (without
         documents incorporated therein by reference or exhibits thereto, unless
         requested);

                    (h)  in the case of a Shelf Registration, cooperate with
         the selling Holders of Transfer Restricted Notes to facilitate the
         timely preparation and delivery of certificates not bearing any
         restrictive legends representing Notes covered by such Shelf
         Registration to be sold and relating to the subsequent transfer of such
         Notes; and cause such Transfer Restricted Notes to be in such
         denominations (consistent with the provisions of the Indenture) and
         registered in such names as the selling Holders may reasonably request
         at least two Business Days prior to the closing of any sale of Transfer
         Restricted Notes;

                    (i)  in the case of a Shelf Registration or an Exchange
         Offer Registration, upon the occurrence of any circumstance
         contemplated by Section 3(e)(ii), 3(e)(iii), 3(e)(iv), 3(e)(v) or
         3(e)(vi) hereof, use their best efforts to prepare a supplement or
         post-effective amendment to a Registration Statement or the related
         Prospectus or any document incorporated therein by reference or file
         any other required document so that, as thereafter delivered to the
         purchasers of the Transfer Restricted Notes, such Prospectus will not
         contain any untrue statement of a material fact or omit to state a
         material fact necessary to make the statements therein, in the light of
         the circumstances under which they were made, not misleading; and to
         notify each Holder to suspend use of the Prospectus as promptly as
         practicable after the occurrence of such an event, and each Holder
         hereby agrees to suspend use of the Prospectus until the Company has
         amended or supplemented the Prospectus to correct such misstatement or
         omission;

                    (j)  obtain a CUSIP number for all Exchange Notes or
         Transfer Restricted Notes, as the case may be, not later than the
         effective date of a Registration Statement, and provide the Trustee
         with certificates for the Exchange Notes or the Transfer Restricted
         Notes, as the case may be, in a form eligible for deposit with the
         Depositary;

                    (k)  cause the Indenture to be qualified under the Trust
         Indenture Act of 1939, as amended, (the "TIA") in connection with the
         registration of the Exchange Notes or Transfer Restricted Notes, as the
         case may be, cooperate with the Trustee and the Holders to effect such
         changes to the Indenture as may be required for the Indenture to be so
         qualified in accordance with the terms of the TIA and execute, and use
         its best efforts to cause the Trustee to execute, all documents as may
         be required to effect such changes, and all other forms and documents
         required to be filed with the SEC to enable the Indenture to be so
         qualified in a timely manner;

                    (l)  in the case of a Shelf Registration, enter into
         such agreements (including underwriting agreements) and take all such
         other appropriate actions as are reasonably requested in order to
         expedite or facilitate the registration or the disposition of such
         Transfer Restricted Notes, and in such connection, (i) make such
         representations and warranties to Holders of such Transfer Restricted
         Notes with respect to the business of the Company and its subsidiaries
         as then conducted and the Registration Statement, Prospectus and
         documents, if any, incorporated or deemed to be incorporated by
         reference therein, in each case, as are customarily made by issuers to
         underwriters in underwritten offerings, and confirm the same if and
         when requested; (ii) obtain opinions of counsel to the Company and
         updates thereof in form and substance reasonably satisfactory to the
         Holders of a majority in principal amount of the Transfer Restricted

         customarily covered in opinions requested in underwritten offerings and
         such other matters as may be reasonably requested by such Holders;
         (iii) obtain "cold comfort" letters and updates thereof from the
         independent certified public accountants of the Company (and, if
         necessary, any other independent certified public accountants of any
         subsidiary of the Company or of any business acquired by the Company
         for which financial statements and financial data are, or are required
         to be, included in the Registration Statement, addressed to the selling
         Holders of Transfer Restricted Notes, such letters to be in customary
         form and covering matters of the type customarily covered in "cold
         comfort" letters in connection with underwritten offerings and such
         other matters as reasonably requested by such selling Holders; and (iv)
         if an underwriting agreement is entered into, the same shall contain
         indemnification provisions and procedures no less favorable than those
         set forth in Section 4 hereof (or such other provisions and procedures
         acceptable to the Company and the Holders of a majority in aggregate
         principal amount of Transfer Restricted Notes covered by such
         Registration with respect to all parties to be indemnified pursuant to
         said Section (including, without limitation, such selling Holders). The
         above shall be done at each closing in respect of the sale of Transfer
         Restricted Notes, or as and to the extent required thereunder;

                    (m)  if (1) a Shelf Registration is filed pursuant to
         Section 2(b) or (2) a Prospectus contained in an Exchange Offer
         Registration Statement filed pursuant to Section 2(a) is required to be
         delivered under the Securities Act by any Participating Broker-Dealer
         who seeks to sell Exchange Notes during the Applicable Period, make
         available for inspection by each such person who would be an
         "underwriter" as a result of either (i) the sale by such person of
         Notes covered by such Shelf Registration Statement or (ii) the sale
         during the Applicable Period by a Participating Broker-Dealer of
         Exchange Notes (provided that a Participating Broker-Dealer shall not
         be deemed to be an underwriter solely as a result of it being required
         to deliver a prospectus in connection with any resale of Exchange
         Notes) and any attorney, accountant or other agent retained by any such
         person (collectively, the "Inspectors"), at the offices where normally
         kept, during reasonable business hours, all financial and other
         records, pertinent corporate documents and properties of the Company
         and its subsidiaries (collectively, the "Records") as shall be
         reasonably necessary to enable them to exercise any applicable due
         diligence responsibilities, and cause the officers, directors and
         employees of the Company and its subsidiaries to supply all information
         in each case reasonably requested by any such Inspector in connection
         with such Registration Statement. Records which the Company determines,
         in good faith, to be confidential and any Records which it notifies the
         Inspectors are confidential shall not be disclosed by the Inspectors
         unless (i) the disclosure of such Records is necessary to avoid or
         correct a material misstatement or omission in such Registration
         Statement, (ii) the release of such Records is ordered pursuant to a
         subpoena or other order from a court of competent jurisdiction or (iii)
         the information in such Records has been made generally available to
         the public. Each selling Holder of such Transfer Restricted Notes and
         each such Participating Broker-Dealer will be required to agree that
         information obtained by it as a result of such inspections shall be
         deemed confidential and shall not be used by it as the basis for any
         market transactions in the securities of the Company unless and until
         such is made generally available to the public. Each selling Holder of
         such Transfer Restricted Notes and each such Participating
         Broker-Dealer will be required to further agree that it will, upon
         learning that disclosure of such Records is sought in a court of
         competent jurisdiction, give notice to the Company and allow the
         Company at its expense to undertake appropriate action to prevent
         disclosure of the Records deemed confidential;

                    (n)  comply with all applicable rules and regulations of
         the SEC and make generally available to its securityholders earnings
         statements satisfying the provisions of Section 11(a) of the Securities
         Act and Rule 158 thereunder (or any similar rule promulgated under the
         Securities Act) no later than 60 days after the end of any 12-month
         period (or 135 days after the end of any 12-month period if such period
         is a fiscal year) (i) commencing at the end of any fiscal quarter in
         which Transfer Restricted Notes are sold to underwriters in a firm
         commitment or best efforts underwritten offering and (ii) if not sold
         to underwriters in such an offering, commencing on the first day of the
         first fiscal quarter of the Company after the effective date of a
         Registration Statement, which statements shall cover said 12-month
         periods;

                    (o)  upon consummation of an Exchange Offer or a Private
         Exchange, obtain an opinion of counsel to the Company addressed to the
         Trustee for the benefit of all Holders of Transfer Restricted Notes
         participating in the Exchange Offer or the Private Exchange, as the
         case may be, and which includes an opinion that (i) the Company has
         duly authorized, executed and delivered the Exchange Notes and Private
         Exchange Notes, and (ii) each of the Exchange Notes or the Private
         Exchange Notes, as the case may be, constitute a legal, valid and
         binding obligation of the Company, enforceable against the Company in
         accordance with its respective terms (in each case, with customary
         exceptions);

                    (p)  if an Exchange Offer or a Private Exchange is to be
         consummated, upon proper delivery of the Transfer Restricted Notes by
         Holders to the Company (or to such other Person as directed by the
         Company) in exchange for the Exchange Notes or the Private Exchange
         Notes, as the case may be, the Company shall mark, or cause to be
         marked, on such Transfer Restricted Notes and on the books of the
         Trustee, the Transfer Agent, the Registrar and the Depositary delivered
         by such Holders that such Transfer Restricted Notes are being canceled
         in exchange for the Exchange Notes or the Private Exchange Notes, as
         the case may be; but in no event shall such Transfer Restricted Notes
         be marked as paid or otherwise satisfied solely as a result of being
         exchanged for Exchange Notes or Private Exchange Notes in the Exchange
         Offer or the Private Exchange, as the case may be;

                    (q)  cooperate with each seller of Transfer Restricted
         Notes covered by any Registration Statement participating in the
         disposition of such Transfer Restricted Notes and one counsel acting on
         behalf of all such sellers in connection with the filings, if any,
         required to be made with the NASD;

                    (r)  use its best efforts to take all other steps
         necessary to effect the registration of the Transfer Restricted Notes
         covered by a Registration Statement contemplated hereby; and

                    (s)  (A) in the case of the Exchange Offer Registration
         Statement (i) include in the Exchange Offer Registration Statement a
         section entitled "Plan of Distribution," which section shall be
         reasonably acceptable to Merrill Lynch, as representative of the
         Initial Purchasers, and which shall contain a summary statement of the
         positions taken or policies made by the staff of the SEC with respect
         to the potential "underwriter" status of any broker-dealer (a
         "Participating Broker-Dealer") that holds Transfer Restricted Notes
         acquired for its own account as a result of market-making activities or
         other trading activities and that will be the beneficial owner (as
         defined in Rule 13d-3 under the Exchange Act) of Exchange Notes to be
         received by such broker-dealer in the Exchange Offer, whether such
         positions or policies have been publicly disseminated by the staff of
         the SEC or such positions or policies, in the reasonable judgment of
         Merrill Lynch, as representative of the Initial Purchasers or such
         other representative, represent the prevailing views of the staff of
         the SEC, including a statement that any such broker-dealer who receives
         Exchange Notes for Transfer Restricted Notes pursuant to the Exchange
         Offer may be deemed a statutory underwriter and must deliver a
         prospectus meeting the requirements of the Securities Act in connection
         with any resale of such Exchange Notes, (ii) furnish to each
         Participating Broker-Dealer who has delivered to the Company the notice
         referred to in Section 3(e), without charge, as many copies of each
         Prospectus included in the Exchange Offer Registration Statement, and
         any amendment or supplement thereto, as such Participating
         Broker-Dealer may reasonably request; (iii) hereby consent to the use
         of the Prospectus forming part of the Exchange Offer Registration
         Statement or any amendment or supplement thereto, by any Person subject
         to the prospectus delivery requirements of the SEC, including all
         Participating Broker-Dealers, in connection with the sale or transfer
         of the Exchange Notes covered by the Prospectus or any amendment or
         supplement thereto, (iv) use their best efforts to keep the Exchange
         Offer Registration Statement effective and to amend and supplement the
         Prospectus contained therein in order to permit such Prospectus to be
         lawfully delivered by all Persons subject to the prospectus delivery
         requirements of the Securities Act for such period of time as such
         Persons must comply with such requirements in order to resell the
         Exchange Notes; provided, however, that such period shall not be
         required to exceed 90 days (or such longer period if extended pursuant
         to the last sentence of Section 3 hereof) (the "Applicable Period"),
         and (iv) include in the transmittal letter or similar documentation to
         be executed by an exchange offeree in order to participate in the
         Exchange Offer (x) the following provision:

                  "If the exchange offeree is a broker-dealer holding Transfer
                  Restricted Notes acquired for its own account as a result of
                  market-making activities or other trading activities, it will
                  deliver a prospectus meeting the requirements of the
                  Securities Act in connection with any resale of Exchange Notes
                  received in respect of such Transfer Restricted Notes pursuant
                  to the Exchange Offer";

         and (y) a statement to the effect that by a broker-dealer making the
         acknowledgment described in clause (x) and by delivering a Prospectus
         in connection with the exchange of Transfer Restricted Notes, such
         broker-dealer will not be deemed to admit that it is an underwriter
         within the meaning of the Securities Act; and

                  (B) in the case of any Exchange Offer Registration Statement,
         the Company agrees to deliver, upon request, to the Trustee or to
         Participating Broker-Dealers upon consummation of the Exchange Offer
         (i) an opinion of counsel substantially in the form attached hereto as
         Exhibit A, and (ii) an officers' certificate containing certifications
         substantially similar to those set forth in Section 7(d) of the
         Purchase Agreement.

                  The Company may require each seller of Transfer Restricted
Notes as to which any registration is being effected to furnish to the Company
such information regarding such seller and the proposed distribution of such
Transfer Restricted Notes, as the Company may from time to time reasonably
request in writing. The Company may exclude from such registration the Transfer
Restricted Notes of any seller who fails to furnish such information within a
reasonable time (not to exceed 10 Business Days) after receiving such request
and shall be under no obligation to compensate any such seller for any lost
income, interest or other opportunity forgone, or any liability incurred, as a
result of the Company's decision to exclude such seller.

                  In the case of (1) a Shelf Registration Statement or (2)
Participating Broker-Dealers who have notified the Company that they will be
utilizing the Prospectus contained in the Exchange Offer Registration Statement
as provided in Section 3(t) hereof, that are seeking to sell Exchange Notes and
are required to deliver Prospectuses, each Holder agrees that, upon receipt of
any notice from the Company of the happening of any event of the kind described
in Section 3(e)(ii), 3(e)(iii), 3(e)(v), 3(e)(vi) or 3(e)(vii) hereof, such
Holder will forthwith discontinue disposition of Transfer Restricted Notes
pursuant to a Registration Statement until such Holder's receipt of the copies
of the supplemented or amended Prospectus contemplated by Section 3(i) hereof or
until it is advised in writing (the "Advice") by the Company that the use of the
applicable Prospectus may be resumed, and, if so directed by the Company, such
Holder will deliver to the Company (at the Company's expense) all copies in such
Holder's possession, other than permanent file copies then in such Holder's
possession, of the Prospectus covering such Transfer Restricted Notes or
Exchange Notes, as the case may be, current at the time of receipt of such
notice. If the Company shall give any such notice to suspend the disposition of
Transfer Restricted Notes or Exchange Notes, as the case may be, pursuant to a
Registration Statement, the Company shall use its best efforts to file and have
declared effective (if an amendment) as soon as practicable an amendment or
supplement to the Registration Statement and, in the case of an amendment, have
such amendment declared effective as soon as practicable and shall extend the
period during which such Registration Statement shall be maintained effective
pursuant to this Agreement by the number of days in the period from and
including the date of the giving of such notice to and including the date when
the Company shall have made available to the Holders (x) copies of the
supplemented or amended Prospectus necessary to resume such dispositions or (y)
the Advice.

                  4. Indemnification and Contribution. (a) The Company shall
indemnify and hold harmless each Initial Purchaser, each Holder, each
Participating Broker-Dealer, each underwriter who participates in an offering of
Transfer Restricted Notes, their respective affiliates, each Person, if any, who
controls any of such parties within the meaning of Section 15 of the Securities
Act or Section 20 of the Exchange Act, as follows:

                   (i)  against any and all loss, liability, claim, damage
         and expense whatsoever, joint or several, as incurred, arising out of
         any untrue statement or alleged untrue statement of a material fact
         contained in any Registration Statement (or any amendment or supplement
         thereto), covering Transfer Restricted Notes or Exchange Notes,
         including all documents incorporated therein by reference, or the
         omission or alleged omission therefrom of a material fact required to
         be stated therein or necessary to make the statements therein not
         misleading or arising out of any untrue statement or alleged untrue
         statement of a material fact contained in any Prospectus (or any
         amendment or supplement thereto) or the omission or alleged omission
         therefrom of a material fact necessary in order to make the statements
         therein, in the light of the circumstances under which they were made,
         not misleading;

                  (ii)  against any and all loss, liability, claim, damage
         and expense whatsoever, joint or several, as incurred, to the extent of
         the aggregate amount paid in settlement of any litigation, or any
         investigation or proceeding by any court or governmental agency or
         body, commenced or threatened, or of any claim whatsoever based upon
         any such untrue statement or omission, or any such alleged untrue
         statement or omission; provided that (subject to Sections 4(c) and 4(d)
         below) any such settlement is effected with the prior written consent
         of the Company; and

                 (iii)  against any and all expenses whatsoever, as
         incurred (including reasonable fees and disbursements of one counsel
         (in addition to any local counsel) chosen by Merrill Lynch, such
         Holder, such Participating Broker-Dealer or any underwriter (except to
         the extent otherwise expressly provided in Section 4(c) hereof)),
         reasonably incurred in investigating, preparing or defending against
         any litigation, or any investigation or proceeding by any court or
         governmental agency or body, commenced or threatened, or any claim
         whatsoever based upon any such untrue statement or omission, or any
         such alleged untrue statement or omission, to the extent that any such
         expense is not paid under subparagraph (i) or (ii) of this Section
         4(a);

provided, however, that this indemnity does not apply to any loss, liability,
claim, damage or expense to the extent arising out of an untrue statement or
omission or alleged untrue statement or omission (i) made in reliance upon and
in conformity with written information furnished in writing to the Company by or
on behalf of such Initial Purchaser, such Holder, such Participating
Broker-Dealer or any underwriter with respect to such Initial Purchaser, Holder,
Participating Broker-Dealer or underwriter, as the case may be, expressly for
use in the Registration Statement (or any amendment or supplement thereto) or
any Prospectus (or any amendment or supplement thereto) or (ii) contained in any
preliminary prospectus if such Initial Purchaser, such Holder, such
Participating Broker-Dealer or such underwriter failed to send or deliver a copy
of the Prospectus (in the form it was first provided to such parties for
confirmation of sales) to the Person asserting such losses, claims, damages or
liabilities on or prior to the delivery of written confirmation of any sale of
securities covered thereby to such Person in any case where the Company shall
have previously furnished copies thereof to such Initial Purchaser, such Holder,
such Participating Broker-Dealer or such underwriter, as the case may be, in
accordance with this Agreement, at or prior to the written confirmation of the
sale of such Notes to such Person and the untrue statement contained in or the
omission from the preliminary prospectus was corrected in the Final Prospectus
(or any amendment or supplement thereto). Any amounts advanced by the Company to
an indemnified party pursuant to this Section 4 as a result of such losses shall
be returned to the Company if it shall be finally determined by a court of
competent jurisdiction in a judgment not subject to appeal or final review that
such indemnified party was not entitled to indemnification by the Company.

                  (b) Each Holder agrees, severally and not jointly, to
indemnify and hold harmless the Company, each Initial Purchaser, each
underwriter who participates in an offering of Transfer Restricted Notes and the
other selling Holders and each of their respective directors and each Person, if
any, who controls any of the Company, any Initial Purchaser, any underwriter or
any other selling Holder within the meaning of Section 15 of the Act or Section
20 of the Exchange Act, against any and all loss, liability, claim, damage and
expense whatsoever described in the indemnity contained in Section 4(a) hereof,
as incurred, but only with respect to untrue statements or omissions, or alleged
untrue statements or omissions, made in the Registration Statement (or any
amendment or supplement thereto) or any Prospectus (or any amendment or
supplement thereto) in reliance upon and in conformity with written information
furnished to the Company by or on behalf of such selling Holder with respect to
such Holder expressly for use in the Registration Statement (or any supplement
thereto), or any such Prospectus (or any amendment thereto); provided, however,
that, in the case of the Shelf Registration Statement, no such Holder shall be
liable for any claims hereunder in excess of the amount of net proceeds received
by such Holder from the sale of Transfer Restricted Notes pursuant to the Shelf
Registration Statement; provided, further, however, that for purposes of Section
4(a)(iii), such counsel shall (subject to Section 4(c) hereof) be chosen by the
Company.

                  (c) Each indemnified party shall give notice as promptly as
reasonably practicable to each indemnifying party of any action commenced
against it in respect of which indemnity may be sought hereunder, but failure to
so notify an indemnifying party shall not relieve such indemnifying party from
any liability hereunder to the extent it is not materially prejudiced as a
result thereof and in any event shall not relieve it from any liability which it
may have otherwise than on account of this indemnity agreement. In the case of
parties indemnified pursuant to Section 4(a) above, one counsel to all the
indemnified parties shall be selected by Merrill Lynch, and, in the case of
parties indemnified pursuant to Section 4(b) above, counsel to all the
indemnified parties shall be selected by the Company. An indemnifying party may
participate at its own expense in the defense of any such action; provided,
however, that counsel to the indemnifying party shall not (except with the
consent of the indemnified party) also be counsel to the indemnified party.
Notwithstanding the foregoing, if it so elects within a reasonable time after
receipt of such notice, an indemnifying party, jointly with any other
indemnifying parties receiving such notice, may assume the defense of such
action with counsel chosen by it and approved by the indemnified parties
defendant in such action (which approval shall not be unreasonably withheld),
unless such indemnified parties reasonably object to such assumption on the
ground that there may be legal defenses available to them which are different
from or in addition to those available to such indemnifying party. If an
indemnifying party assumes the defense of such action, the indemnifying parties
shall not be liable for any fees and expenses of counsel for the indemnified
parties incurred thereafter in connection with such action. In no event shall
the indemnifying parties be liable for fees and expenses of more than one
counsel (in addition to any local counsel) separate from their own counsel for
all indemnified parties in connection with any one action or separate but
similar or related actions arising out of the same general allegations or
circumstances. No indemnifying party shall, without the prior written consent of
the indemnified parties, settle or compromise or consent to the entry of any
judgment with respect to any litigation, or any investigation or proceeding by
any governmental agency or body, commenced or threatened, or any claim
whatsoever in respect of which indemnification or contribution could be sought
under this Section 4 (whether or not the indemnified parties are actual or
potential parties thereto), unless such settlement, compromise or consent (i)
includes a full and unconditional release of each indemnified party from all
liability arising out of such litigation, investigation, proceeding or claim and
the offer and sale of any Notes and (ii) does not include a statement as to or
an admission of fault, culpability or a failure to act by or on behalf of any
indemnified party.

                  (d) If at any time an indemnified party shall have requested
an indemnifying party to reimburse the indemnified party for reasonable fees and
expenses of counsel pursuant to Section 4(a)(iii) above, then such indemnifying
party agrees that it shall be liable for any settlement of the nature
contemplated by Section 4(a)(ii) effected without its written consent if (i)
such settlement is entered into more than 45 days after receipt by such
indemnifying party of the aforesaid request, (ii) such indemnifying party shall
have received notice of the terms of such settlement at least 30 days prior to
such settlement being entered into and (iii) such indemnifying party shall not
have reimbursed such indemnified party in accordance with such request prior to
the date of such settlement.

                  (e) In order to provide for just and equitable contribution in
circumstances under which any of the indemnity provisions set forth in this
Section 4 is for any reason held to be unavailable to the indemnified parties
although applicable in accordance with its terms, the Company, the Initial
Purchasers and the Holders, as applicable, shall contribute to the aggregate
losses, liabilities, claims, damages and expenses of the nature contemplated by
such indemnity agreement incurred by the Company, the Initial Purchasers and the
Holders; provided, however, that no Person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Securities Act)
shall be entitled to contribution from any Person that was not guilty of such
fraudulent misrepresentation. As between the Company and the Initial Purchasers
and the Holders, such parties shall contribute to such aggregate losses,
liabilities, claims, damages and expenses of the nature contemplated by such
indemnity agreement in such proportion as shall be appropriate to reflect the
relative fault of the Company on the one hand and of the Holder of Transfer
Restricted Notes, the Participating Broker-Dealer or Initial Purchaser, as the
case may be, on the other hand in connection with the statements or omissions
which resulted in such losses, liabilities, claims, damages or expenses, as well
as any other relevant equitable considerations.

                  The relative fault of the Company on the one hand and the
Holder of Transfer Restricted Notes, the Participating Broker-Dealer or the
Initial Purchasers, as the case may be, on the other hand shall be determined by
reference to, among other things, whether the untrue or alleged untrue statement
of a material fact or the omission or alleged omission to state a material fact
relates to information supplied by the Company, or by the Holder of Transfer
Restricted Notes, the Participating Broker-Dealer or the Initial Purchasers, as
the case may be, and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission.

                  The Company and the Holders of the Transfer Restricted Notes
and the Initial Purchasers agree that it would not be just and equitable if
contribution pursuant to this Section 4 were determined by pro rata allocation
or by any other method of allocation which does not take account of the
equitable considerations referred to above in this Section 4.

                  For purposes of this Section 4, each affiliate of any Person,
if any, who controls a Holder of Transfer Restricted Notes, an Initial Purchaser
or a Participating Broker-Dealer within the meaning of Section 15 of the
Securities Act or Section 20 of the Exchange Act shall have the same rights to
contribution as such other Person, and each director of the Company, each
affiliate of the Company, each executive officer of the Company who signed the
Registration Statement, and each Person, if any, who controls the Company within
the meaning of Section 15 of the Securities Act or Section 20 of the Exchange
Act shall have the same rights to contribution as the Company.

                  5.  Miscellaneous.

                  (a) Rule 144 and Rule 144A. The Company shall provide to each
Holder such reports as are required under Section 10.24 of the Indenture and,
upon the request of any Holder of Transfer Restricted Notes (a) make publicly
available such information as is necessary to permit sales pursuant to Rule 144
under the Securities Act, (b) deliver such information to a prospective
purchaser as is necessary to permit sales pursuant to Rule 144A under the
Securities Act and it will take such further action as any Holder of Transfer
Restricted Notes may reasonably request, and (c) take such further action, if
any, that is reasonable in the circumstances, in each case, to the extent
required from time to time to enable such Holder to sell its Transfer Restricted
Notes without registration under the Securities Act within the limitation of the
exemptions provided by (i) Rule 144 under the Securities Act, as such rule may
be amended from time to time, (ii) Rule 144A under the Securities Act, as such
rule may be amended from time to time, or (iii) any similar rules or regulations
hereafter adopted by the SEC. Upon the reasonable request of any Holder of
Transfer Restricted Notes, the Company will deliver to such Holder a written
statement as to whether they have complied with such requirements.

                  (b) No Inconsistent Agreements. The rights granted to the
Holders hereunder do not, and will not for the term of this Agreement in any way
conflict with and are not, and will not during the term of this Agreement be
inconsistent with the rights granted to the holders of the Company's other
issued and outstanding securities under any other agreements entered into by the
Company.

                  (c) Amendments and Waivers. The provisions of this Agreement,
including 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, otherwise than with the prior written consent of the Company
and the Majority Holders; provided, however, that no amendment, modification, or
supplement or waiver or consent to the departure with respect to the provisions
of Section 4 hereof shall be effective as against any Holder of Transfer
Restricted Notes or the Company unless consented to in writing by such Holder of
Transfer Restricted Notes or the Company, as the case may be.

                  (d) Notices. All notices and other communications provided for
or permitted hereunder shall be made in writing by hand-delivery, registered
first-class mail, telex, telecopier, or any courier guaranteeing overnight
delivery (i) if to a Holder, at the most current address given by such Holder to
the Company by means of a notice given in accordance with the provisions of this
Section 5(d), which address initially is, with respect to the Initial
Purchasers, the address set forth in the Purchase Agreement; and (ii) if to the
Company, initially at the Company's address set forth in the Purchase Agreement
and thereafter at such other address, notice of which is given in accordance
with the provisions of this Section 5(d).

                  All such notices and communications shall be deemed to have
been duly given: at the time delivered by hand, if personally delivered; five
Business Days after being deposited in the mail, postage prepaid, if mailed;
when answered back, if telexed; when receipt is acknowledged, if telecopied; and
on the next Business Day, if timely delivered to an air courier guaranteeing
overnight delivery.

                  Copies of all such notices, demands, or other communications
shall be concurrently delivered by the Person giving the same to the Trustee, at
the address specified in the Indenture.

                  (e) Successors and Assigns. This Agreement shall inure to the
benefit of and be binding upon the successors, assigns and transferees of the
Initial Purchasers, including, without limitation and without the need for an
express assignment, subsequent Holders; provided, however, that nothing herein
shall be deemed to permit any assignment, transfer or other disposition of
Transfer Restricted Notes in violation of the terms of the Purchase Agreement or
the Indenture. If any transferee of any Holder shall acquire Transfer Restricted
Notes, in any manner, whether by operation of law or otherwise, such Transfer
Restricted Notes shall be held subject to all of the terms of this Agreement,
and by taking and holding such Transfer Restricted Notes, such Person shall be
conclusively deemed to have agreed to be bound by and to perform all of the
terms and provisions of this Agreement and such Person shall be entitled to
receive the benefits hereof.

                  (f) Third Party Beneficiary. Each of the Initial Purchasers
and each Holder shall be a third party beneficiary of the agreements made
hereunder between the Company, on the one hand, and the Initial Purchasers, on
the other hand, and shall have the right to enforce such agreements directly to
the extent it deems such enforcement necessary or advisable to protect its
rights or the rights of Holders hereunder.

                  (g) Counterparts. This Agreement may be executed in any number
of counterparts and by the parties hereto in separate counterparts, each of
which when so executed shall be deemed to be an original and all of which taken
together shall constitute one and the same agreement.

                  (h) Headings. The headings in this Agreement are for
convenience of reference only and shall not limit or otherwise affect the
meaning hereof.

                  (i) GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED BY AND
CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, WITHOUT GIVING
EFFECT TO ANY PROVISIONS RELATING TO CONFLICTS OF LAWS. Specified times of day
refer to New York City time.

                  (j) Severability. In the event that any one or more of the
provisions contained herein, or the application thereof in any circumstance, is
held invalid, illegal or unenforceable, the validity, legality and
enforceability of any such provision in every other respect and of the remaining
provisions contained herein shall not be affected or impaired thereby.

                  (k) Notes Held by the Company or any of its Affiliates.
Whenever the consent or approval of Holders of a specified percentage of
Transfer Restricted Notes is required hereunder, Transfer Restricted Notes held
by the Company or any of their affiliates (as such term is defined in Rule 405
under the Securities Act) shall not be counted in determining whether such
consent or approval was given by the Holders of such required percentage.

                            [Signature Page Follows]

                           Form of Opinion of Counsel

                  1.  Each of the Exchange Offer Registration Statement
and the Prospectus (other than the financial statements, notes or schedules
thereto and other financial and statistical information and supplemental
schedules included or referred to therein or omitted therefrom and the Form T-1,
as to which such counsel need express no opinion), complies as to form in all
material respects with the applicable requirements of the Securities Act and the
applicable rules and regulations promulgated under the Securities Act.

                  2.  In the course of such counsel's review and
discussion of the contents of the Exchange Offer Registration Statement and the
Prospectus with certain officers and other representatives of the Company and
representatives of the independent certified public accountants of the Company,
but without independent check or verification or responsibility for the
accuracy, completeness or fairness of the statements contained therein, on the
basis of the foregoing (relying as to materiality to a large extent upon
representations and opinions of officers and other representatives of the
Company), no facts have come to such counsel's attention which cause such
counsel to believe that the Exchange Offer Registration Statement (other than
the financial statements, notes and schedules thereto and other financial and
statistical information contained or referred to therein and the Form T-1, as to
which such counsel need express no belief), at the time the Exchange Offer
Registration Statement became effective and at the time of the 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 contained therein not misleading, or that the Prospectus (other than
the financial statements, notes and schedules thereto and other financial and
statistical information contained or referred to therein, as to which such
counsel need express no belief) contains any untrue statement of a material fact
or omits to state a material fact necessary to make the statements contained
therein, in the light of the circumstances under which they were made, not
misleading.

RCN Corporation
105 Carnegie Center
Princeton, New Jersey 08540-6215

Ladies and Gentlemen:

               We have acted as special counsel to RCN Corporation, a Delaware
company (the "Company"), in connection with the preparation of a Registration
Statement on Form S-4 (the "Registration Statement") filed with the Securities
and Exchange Commission under the Securities Act of 1933, as amended (the
"Securities Act"), relating to the proposed exchange of 9.80% Senior Discount
Notes Due 2008, Series B of the Company (the "New Notes") for any and all of
the Company's issued and outstanding 9.80% Senior Discount Notes Due 2008,
Series A (the "Old Notes") .  Capitalized terms used herein have the meanings
set forth in the Registration Statement, unless otherwise defined herein.

               We have examined the originals, or certified, conformed or
reproduction copies, of all such records, agreements, instruments and
documents as we have deemed relevant or necessary as the basis for the
opinions hereinafter expressed.  In all such examinations, we have relied upon
the genuineness of all signatures, the authenticity of all original or
certified copies and the conformity to original or certified copies of all
copies submitted to us as conformed or reproduction copies.  We also have
assumed, with respect to all parties to agreements or instruments relevant
hereto other than the Company, that such parties had the requisite power and
authority (corporate or otherwise) to execute, deliver and perform such
agreements or instruments, that such agreements or instruments have been duly
authorized by all requisite action (corporate or otherwise), executed and
delivered by such parties and that such agreements or instruments are the
valid, binding and enforceable obligations of such parties.  As to various
questions of fact relevant to such opinions, we have relied upon, and have
assumed the accuracy of, certificates and oral or written statements and other
information of or from public officials, officers or representatives of the
Company and others.

               Based upon the foregoing and subject to the other limitations,
qualifications and assumptions set forth herein, we are of the opinion that,
(i) the Company has duly authorized, executed and delivered the New Notes and
(ii) when the Registration Statement has become effective under the Securities
Act and the New Notes have been duly authenticated by the Trustee in accordance
with the terms of the Indenture and delivered in exchange for the Old Notes in
accordance with the terms of the Indenture, the New Notes will constitute valid
and binding obligations of the Company, enforceable in accordance with their
terms and entitled to the benefits of the Indenture, subject to (A) bankruptcy,
insolvency, reorganization, fraudulent transfer, moratorium or other laws now
or hereafter in effect affecting creditors' rights generally, and (B) general
principles of equity (including, without limitation, standards of materiality,
good faith, fair dealing and reasonableness) whether considered in a
proceeding in equity or at law.

               We are members of the Bar of the State of New York and the
foregoing opinion is limited to the laws of the State of New York, the General
Corporation Law of the State of Delaware and the federal laws of the United
States of America.

               We hereby consent to the filing of this opinion as an Exhibit
to the Registration Statement and to the reference to this firm under the
caption "Legal Matters" in the Prospectus that is included in the Registration
Statement.

               The opinions expressed herein are solely for your benefit and
may not be relied upon for any purpose except as specifically provided for
herein, or relied upon by any other person, firm or corporation for any
purpose, without our prior written consent.

                                                Very truly yours,

                                                /s/ Davis Polk & Wardwell

</TABLE>


For purposes of computing the ratio, earnings are income from continuing
operations less minority interest in income of consolidated entities and plus
fixed charges. Fixed charges consist of interest on long- and short-term debt
including amortization of debt expense. The ratio of earnings to fixed charges
for the year ended December 31, 1997 is less than 1 and therefore the earnings
are inadequate to cover the fixed charges by $73,522.

     The undersigned acknowledges receipt of the Prospectus dated [ ], 1998 (the
"Prospectus") of RCN Corporation (the "Company") which, together with this
Letter of Transmittal (the "Letter of Transmittal"), describes the Company's
offer (the "Exchange Offer") to exchange $1,000 in principal amount of a new
series of 9.80% Senior Discount Notes due 2008, Series B (CUSIP # 749361 [ ])
(the "New Discount Notes") for each $1,000 in principal amount of outstanding
9.80% Senior Discount Notes due 2008, Series A (CUSIP #749361AE1) (the "Old
Discount Notes"). The terms of the New Discount Notes are identical in all
material respects (including principal amount, interest rate and maturity) to
the terms of the Old Discount Notes for which they may be exchanged pursuant to
the Exchange Offer, except that the offering of the New Discount Notes will have
been registered under the Securities Act of 1933, as amended and, therefore, the
New Discount Notes will not bear legends restricting the transfer thereof.

     The undersigned has checked the appropriate boxes below and signed this
Letter of Transmittal to indicate the action the undersigned desires to take
with respect to the Exchange Offer.

     PLEASE READ THE ENTIRE LETTER OF TRANSMITTAL AND THE PROSPECTUS CAREFULLY
BEFORE CHECKING ANY BOX BELOW.

is to be made by book-entry transfer to an account maintained by the Exchange
Agent at The Depository Trust Company ("DTC"), pursuant to the procedures set
forth in "The Exchange Offer--Book-Entry Transfer" in the Prospectus. Delivery
of documents to a book-entry transfer facility does not constitute delivery to
the Exchange Agent.

this Letter of Transmittal means any person in whose name Old Discount Notes are
registered on the books of the Company or any other person who has obtained a
properly completed bond power from the registered holder or any person whose Old

               PLEASE READ THE ACCOMPANYING INSTRUCTIONS CAREFULLY

Ladies and Gentlemen:

     Upon the terms and subject to the conditions of the Exchange Offer, the
undersigned hereby tenders to the Company the above-described principal amount
of Old Discount Notes. Subject to, and effective upon, the acceptance for
exchange of the Old Discount Notes tendered herewith, the undersigned hereby
exchanges, assigns and transfers to, or upon the order of, the Company all
right, title and interest in and to such Old Discount Notes. The undersigned
hereby irrevocably constitutes and appoints the Exchange Agent as the true and
lawful agent and attorney-in-fact of the undersigned (with full knowledge that
said Exchange Agent acts as the agent of the undersigned in connection with the
Exchange Offer) to cause the Old Discount Notes to be assigned, transferred and
exchanged. The undersigned represents and warrants that it has full power and
authority to tender, exchange, assign and transfer the Old Discount Notes and to
acquire New Discount Notes issuable upon the exchange of such tendered Old
Discount Notes, and that, when the same are accepted for exchange, the Company
will acquire good and unencumbered title to the tendered Old Discount Notes,
free and clear of all liens, restrictions, charges and encumbrances and not
subject to any adverse claim. The undersigned also warrants that it will, upon
request, execute and deliver any additional documents deemed by the Exchange
Agent or the Company to be necessary or desirable to complete the exchange,
assignment and transfer of tendered Old Discount Notes or transfer ownership of
such Old Discount Notes on the account books maintained by The Depository Trust
Company.

     The Exchange Offer is subject to certain conditions as set forth in the
Prospectus under the caption "The Exchange Offer." The undersigned recognizes
that as a result of these conditions (which may be waived, in whole or in part,
by the Company), as more particularly set forth in the Prospectus, the Company

and, in such event, the Old Discount Notes not exchanged will be returned to the
undersigned at the address shown below the signature of the undersigned.

     BY TENDERING, EACH HOLDER OF OLD DISCOUNT NOTES REPRESENTS TO THE COMPANY

NEITHER THE HOLDER NOR ANY SUCH OTHER PERSON IS AN "AFFILIATE" OF THE COMPANY
WITHIN THE MEANING OF RULE 405 UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE

in the Prospectus under the caption "The Exchange Offer--Guaranteed Delivery
Procedures."

     No alternative, conditional, irregular or contingent tenders will be
accepted. All tendering holders, by execution of this Letter of Transmittal (or
facsimile thereof), shall waive any right to receive notice of the acceptance of
the Old Discount Notes for exchange.

       2. PARTIAL TENDERS; WITHDRAWALS. Tenders of Old Discount Notes will be
accepted in all denominations of $1,000 and integral multiples in excess
thereof. If less than the entire principal amount of Old Discount Notes
evidenced by a submitted certificate is tendered, the tendering holder must fill
in the principal amount tendered in the box entitled "Principal Amount
Tendered." A newly issued certificate for the principal amount of Old Discount
Notes submitted but not tendered will be sent to such holder as soon as
practicable after the Expiration Date. All Old Discount Notes delivered to the
Exchange Agent will be deemed to have been tendered unless otherwise indicated.

     Tenders of Old Discount Notes pursuant to the Exchange Offer are
irrevocable, except that Old Discount Notes tendered pursuant to the Exchange
Offer may be withdrawn at any time prior to the Expiration Date. To be
effective, a written, telegraphic or facsimile transmission notice of withdrawal
must be timely received by the Exchange Agent. Any such notice of withdrawal
must specify the person named in the Letter of Transmittal as having tendered
Old Discount Notes to be withdrawn, the certificate numbers of the Old Discount
Notes to be withdrawn, the principal amount of Old Discount Notes delivered for
exchange, a statement that such a holder is withdrawing its election to have
such Old Discount Notes exchanged, and the name of the registered holder of such
Old Discount Notes, and must be signed by the holder in the same manner as the
original signature on the Letter of Transmittal (including any required
signature guarantees) or be accompanied by evidence satisfactory to the Company
that the person withdrawing the tender has succeeded to the beneficial ownership
of the Old Discount Notes being withdrawn. The Exchange Agent will return the
properly withdrawn Old Discount Notes promptly following receipt of notice of
withdrawal. If Old Discount 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 The Depository Trust Company to be credited with the
withdrawn Old Discount Notes or otherwise comply with The Depository Trust
Company's procedures.

       3.  SIGNATURE ON THIS LETTER OF TRANSMITTAL; WRITTEN INSTRUMENTS AND
ENDORSEMENTS; GUARANTEE OF SIGNATURES. If this Letter of Transmittal is signed
by the registered holder(s) of the Old Discount Notes tendered hereby, the
signature must correspond with the name(s) as written on the face of
certificates without alteration, enlargement or any change whatsoever.

     If any of the Old Discount Notes tendered hereby are owned of record by two
or more joint owners, all such owners must sign this Letter of Transmittal.

     If a number of Old Discount Notes registered in different names are
tendered, it will be necessary to complete, sign and submit as many separate
copies of this Letter of Transmittal as there are different registrations of Old
Discount Notes.

     When this Letter of Transmittal is signed by the registered holder or
holders of Old Discount Notes listed and tendered hereby, no endorsements of
certificates or separate written instruments of transfer or exchange are
required.

     If this Letter of Transmittal is signed by a person other than the
registered holder or holders of the Old Discount Notes listed, such Notes must
be endorsed or accompanied by separate written instruments of transfer or
exchange in form satisfactory to the Company and duly executed by the registered
holder, in either case signed exactly as the name or names of the registered
holder or holders appear(s) on the Old Discount Notes.

     If this Letter of Transmittal, any certificates or separate written
instruments of transfer or exchange are signed by trustees, executors,
administrators, guardians, attorneys-in-fact, officers of corporations or others
acting in a fiduciary or representative capacity, such persons should so
indicate when signing, and, unless waived by the Company, proper evidence
satisfactory to the Company of their authority so to act must be submitted.

     Endorsements on certificates or signatures on separate written instruments
of transfer or exchange required by this Instruction 3 must be guaranteed by an
Eligible Institution.

     Signatures on this Letter of Transmittal need not be guaranteed by an
Eligible Institution, provided the Old Discount Notes are tendered: (i) by a
registered holder of such Old Discount Notes and the certificates for New
Discount Notes to be issued in exchange therefor are to be issued (or any
untendered amount of Old Discount Notes are to be reissued) to the registered
holder; or (ii) for the account of any Eligible Institution.

       4. TRANSFER TAXES. The Company shall pay all transfer taxes, if any,
applicable to the transfer and exchange of Old Discount Notes to it or its order
pursuant to the Exchange Offer. If, however, New Discount Notes 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 Discount Notes tendered hereby, or if a
transfer tax is imposed for any reason other than the transfer of Old Discount
Notes to the Company or its order pursuant to the Exchange Offer, 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 exception therefrom is not submitted herewith the
amount of such transfer taxes will be billed directly to such tendering holder.

     Except as provided in this Instruction 4, it will not be necessary for
transfer tax stamps to be affixed to the Old Discount Notes listed in this
Letter of Transmittal.

       5. WAIVER OF CONDITIONS. The Company reserves the absolute right to
waive, in whole or in part, any of the conditions to the Exchange Offer set
forth in the Prospectus.

Discount Notes will be resolved by the Company, whose determination will be
final and binding. The Company reserves the absolute right to reject any or all
Letters of Transmittal or tenders that are not in proper form or the acceptance
of which would, in the opinion of the Company's counsel, be unlawful. The
Company also reserves the right to waive any irregularities or conditions of
tender as to the particular Old Discount Notes covered by any Letter of
Transmittal or tendered pursuant to such letter. None of the Company, the
Exchange Agent or any other person will be under any duty to give notification
