(Cover page continued)

    WinStar Communications, Inc., a Delaware corporation ("Company"), hereby 
offers, upon the terms and subject to the conditions set forth in this 
Prospectus and the letter of transmittal ("Letter of Transmittal") to be 
delivered to each holder of Old Notes (as defined below), to exchange 
("Exchange Offer") $1,000 principal amount of its 15% Senior Subordinated 
Deferred Interest Exchange Notes Due 2007 ("New Notes") for each $1,000 
principal amount of its outstanding 15% Senior Subordinated Deferred Interest 
Notes Due 2007 ("Old Notes").  The Old Notes and the New Notes are referred 
to herein collectively as the "Notes."

    The New Notes will be registered under the Securities Act of 1933, as 
amended ("Securities Act"), pursuant to the registration statement on Form 
S-4 ("Registration Statement") of which this Prospectus forms a part.  As of 
the date hereof, $100.0 million principal amount of the Old Notes were 
outstanding.  The Registration Statement of which this Prospectus forms a 
part has been filed by the Company in accordance with the terms of the 
Purchase Agreement, dated as of October 1, 1997 ("Purchase Agreement"), and 
Registration Rights Agreement, dated as of October 1, 1997  ("Registration 
Agreement"), between the Company and Credit Suisse First Boston Corporation 
and BT Alex Brown Incorporated, the initial purchasers of the Old Notes 
("Initial Purchasers").  The Exchange Offer is being made by the Company to 
fulfill certain obligations under the Purchase Agreement and Registration 
Agreement. After the consummation of the Exchange Offer, the Company will 
have no further obligation to make any other such exchange offers.

    The Company will accept for exchange any and all Old Notes that are 
validly tendered and not withdrawn on or prior to 5:00 p.m., New York City 
time, on the date the Exchange Offer expires, which will be December __, 
1997, unless the Exchange Offer is extended by the Company in its sole 
discretion ("Expiration Date").  Tenders of Old Notes may be withdrawn at any 
time prior to 5:00 p.m., New York City time, on the Expiration Date.  The 
Exchange Offer is not conditioned upon any minimum principal amount of Old 
Notes being tendered for exchange. However, the Exchange Offer is subject to 
certain conditions which may be waived by the Company and to the terms and 
provisions of the Registration Statement.  The Old Notes may be tendered only 
in denominations of $1,000 principal amount and integral multiples thereof.  
The Company has agreed to pay all expenses related to the Exchange Offer, 
except costs related to the delivery of the Old Notes by each holder of such 
notes to the United States Trust Company of New York, the exchange agent 
("Exchange Agent" or "U.S. Trust"), and underwriting discounts, commissions 
and transfer taxes.  Any waiver, extension or termination of the Exchange 
Offer will be publicly announced by the Company through a release to the Dow 
Jones News Service and as otherwise required by applicable laws or 
regulations. See "The Exchange Offer."

    The New Notes will be entitled to the benefits of the indenture under 
which the Old Notes were issued (the "Indenture").  The form of the New Notes 
will be identical to the form of the Old Notes, except that the New Notes 
will have been registered under the Securities Act and, therefore, will not 
bear legends restricting the transfer thereof. The New Notes will have the 
same terms, conditions and rankings as the Old Notes.  The Notes are 
unsecured, senior subordinated obligations of the Company, rank pari passu in 
right of payment with the Company's existing 14% Convertible Senior 
Subordinated Discount Notes Due 2005 ("Convertible Notes"), and are junior in 
right of payment to all existing and future senior indebtedness of the 
Company.

    The Notes bear interest at a rate of 15% per annum, payable on March 1 
and September 1, commencing September 1, 2002.  Until March 1, 2002, interest 
on the Notes will accrue and be compounded semiannually on each SemiAnnual 
Interest Accrual Date (as defined), but will not be payable in cash.  
Interest on the Accumulated Amount (as defined) of the Notes as of March 1, 
2002 will be payable semiannually commencing September 1, 2002.  The Notes 
will mature on March 1, 2007 and are redeemable on or after March 1, 2002, at 
the option of the Company, in whole or in part, at the redemption prices set 
forth herein.

    Based on no-action letters issued by the staff of the Securities and 
Exchange Commission ("Commission") to third parties, the Company believes 
that New Notes issued pursuant to this Exchange Offer in exchange for Old 
Notes may be offered for resale, resold and otherwise transferred by a holder 
thereof (other than a broker-dealer who purchased such Old Notes directly 
from the Company to resell pursuant to Rule 144A or any other available 
exemption under the Securities Act) without compliance with the registration 
and prospectus delivery provisions of the Securities Act, provided that the 
holder is acquiring the New Notes in the ordinary course of its business and 
is not participating, and has no arrangement or understanding with any person 
to participate, in the distribution of the New Notes.  Holders 

                                       2

(Cover page continued)

of Old Notes 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 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 by delivering a prospectus, a 
broker-dealer will not be deemed to admit that it is an "underwriter" within 
the meaning of the Securities Act.  This Prospectus, as it may be amended or 
supplemented from time to time, may be used by a broker-dealer in connection 
with resales of New Notes received in exchange for Old Notes where such Old 
Notes were acquired by such broker-dealer as a result of market-making 
activities or other trading activities.  The Company has agreed that, for a 
period of 180 days after the Expiration Date, it will make this Prospectus 
available to any broker-dealer for use in connection with any such resale.  
See "Plan of Distribution." 

    As of November ___, 1997, Cede & Co. ("Cede"), as nominee for The 
Depository Trust Company, New York, New York ("DTC"), was the registered 
holder of $100.0 million aggregate principal amount of the Old Notes and held 
such Old Notes for _____ of its participants. The Company believes that no 
such participant is an affiliate (as such term is defined in Rule 405 of the 
Securities Act) of the Company.  There has previously been only a limited 
secondary market, and no public market, for the Old Notes. The Old Notes are, 
and the New Notes will be, eligible for trading in the Private Offering, 
Resales and Trading through Automatic Linkages ("PORTAL") market. There can 
be no assurance as to the liquidity of the trading market for either the New 
Notes or the Old Notes. The New Notes constitute securities for which there 
is no established trading market, and the Company does not currently intend 
to list the New Notes on any securities exchange. If such a trading market 
develops for the New Notes, future trading prices will depend on many 
factors, including, among other things, prevailing interest rates, the 
Company's results of operations and the market for similar securities. 
Depending on such factors, the New Notes may trade at a discount from their 
face value.  See "Risk Factors -- Absence of Public Market for the New Notes."

    Any Old Notes not tendered and accepted in the Exchange Offer will remain 
outstanding and will be entitled to all the rights and preferences and will 
be subject to the limitations applicable thereto under the Indenture.  
Following the consummation of the Exchange Offer, the holders of Old Notes 
will continue to be subject to the existing restrictions upon transfer 
thereof and the Company will have no further obligation to such holders to 
provide for any other exchange offer with respect to the Old Notes held by 
such holders.  Following the completion of the Exchange Offer in accordance 
with the terms hereof and the Registration Agreement, certain of the Old 
Notes may not be entitled to the contingent increase in interest rate as 
provided in the Registration Agreement.  See "The Exchange Offer."

    This Prospectus, together with the Letter of Transmittal, is being sent 
to all registered holders of Old Notes as of December __, 1997.

    The Company will not receive any proceeds from this Exchange Offer.  No 
dealer-manager is being used in connection with this Exchange Offer.  See 
"Plan of Distribution."

                                       3

    THE EXCHANGE OFFER IS NOT BEING MADE TO, NOR WILL THE COMPANY ACCEPT 
SURRENDERS FOR EXCHANGE FROM, HOLDERS OF OLD NOTES IN ANY JURISDICTION IN 
WHICH THE EXCHANGE OFFER OR THE ACCEPTANCE THEREOF WOULD NOT BE IN COMPLIANCE 
WITH THE SECURITIES OR BLUE SKY LAWS OF SUCH JURISDICTION.

    The Old Notes were issued originally in global form (the "Old Global 
Notes"). The Old Global Notes were deposited with, or on behalf of, DTC, as 
the initial depository with respect to the Old Notes (in such capacity, the 
"Depository").  The Old Global Notes are registered in the name of Cede, as 
nominee of DTC, and beneficial interests in the Old Global Notes are shown 
on, and transfers thereof are effected only through, records maintained by 
the Depository and its participants. The use of the Old Global Notes to 
represent the Old Notes permits the Depository's participants, and anyone 
holding a beneficial interest in an Old Note registered in the name of such a 
participant, to transfer interests in the Old Notes electronically in 
accordance with the Depository's established procedures without the need to 
transfer a physical certificate.  Except as provided below, the New Notes 
will also be issued initially as a note in global form (the "New Global 
Notes", and together with the Old Global Notes, the "Global Notes") and 
deposited with, or on behalf of, the Depository.  Notwithstanding the 
foregoing, any holder of Old Notes who at any time is not a qualified 
institutional buyer under Rule 144A (a "Qualified Institutional Buyer"), who 
exchanges Old Notes in the Exchange Offer, will receive the New Notes in 
certificated form.  Any such holder is not, and will not be, able to trade 
such securities through the Depository unless the New Notes are resold to a 
Qualified Institutional Buyer. After the initial issuance of the New Global 
Notes, New Notes in certificated form will be issued in exchange for a 
holder's proportionate interest in the New Global Notes only as set forth in 
the Indenture.

    No person has been authorized to give any information or to make any 
representations in connection with the Exchange Offer other than those 
contained in this Prospectus and the Letter of Transmittal and, if given or 
made, such information or representation must not be relied upon as having 
been authorized by the Company or the Exchange Agent. This Prospectus does 
not constitute an offer to sell or a solicitation of an offer to buy the New 
Notes in any jurisdiction to any person to whom it is unlawful to make such 
offer or solicitation in such jurisdiction.  The delivery of this Prospectus 
shall not, under any circumstances, create any implication that the 
information herein is correct at any time subsequent to its date.

other information as it would be required to file with the Commission by

    This summary is qualified in its entirety by the detailed information and 
financial statements and notes thereto appearing elsewhere or incorporated by 
reference in this Prospectus.  Unless otherwise indicated, references herein 
to the "Company" or "WinStar" refer to WinStar Communications, Inc. and,

                                 The Company

    The Company provides a full range of telecommunications services, 
including local, long distance and Internet access services, as a competitive 
local exchange carrier ("CLEC"). By exploiting its fiber-quality digital 
capacity in the 38 GHz portion of the radio spectrum ("Wireless Fiber") and a 
switch-based infrastructure, the Company seeks to distinguish itself as a 
facilities-based, value-added provider of high-capacity telecommunications 
services to small and medium-sized businesses and an attractive alternative 
to established providers, such as the regional Bell operating companies 
("RBOCs"). The Company introduced its switch-based local exchange services to 
end users in New York City in October 1996. The Company is offering local 
exchange services on a switched basis and resale basis in Boston, Chicago, 
Dallas, Forth Worth, Los Angeles, Newark, New York City, San Diego and 
Washington, D.C., and is offering local exchange services solely on a resale 
basis in Atlanta, Hartford, Milwaukee, Orange County (California), 
Philadelphia, San Francisco and Stamford (Connecticut). The Company's local 
exchange services include the provision of PBX trunks, individual business 
lines and Centrex and Internet access, and provide customers with 
full-feature services such as custom calling, caller ID, conference calling 
and voice mail. During the next several years, the Company intends to 
introduce its local exchange services in each of the other major metropolitan 
areas where it is licensed to provide 38 GHz services over four or more 100 
MHz channels. Over time, the Company intends to carry a substantial majority 
of its local telecommunications service traffic utilizing Wireless Fiber and 
its own switched networks, unlike most fiber-based CLECs, which typically do 
not carry the majority of their customer traffic over their own networks. The 
Company also offers a variety of facilities-based broadband, high-capacity 
local access and digital network services ("Carrier Services") to other 
telecommunications service providers on a wholesale basis. As of September 
30, 1997, the Company had more than 40 carrier customers, including, among 
others, Ameritech Cellular Services, MCI Communications, Pacific Bell and 
Teleport Communications Group. 

    The Company is the holder of the largest amount of 38 GHz spectrum in the 
United States and is utilizing this asset to build local telephone networks 
for the transmission of voice, data and video traffic in the major 
metropolitan areas covered by the Company's 38 GHz licenses (the "Wireless 
Licenses"). The Wireless Licenses cover an aggregate of more than 100 cities 
with populations exceeding 100,000 each, and encompass an aggregate 
population of approximately 175 million people and address more than 625 
million channel pops (population coverage multiplied by the number of 100 MHz 
channels). Furthermore, the Wireless Licenses allow the Company to provide 
Wireless Fiber services in 49 of the 50 most populated Metropolitan 
Statistical Areas ("MSAs") in the United States. The Company has agreed to 
acquire an aggregate of certain additional 38 GHz licenses in various 
transactions, subject to approval by the Federal Communications Commission 
("FCC"). Upon completion of these acquisitions, the Company's Wireless 
Licenses will enable the Company to provide services in all of the 50 most 
populated MSAs and will cover cities encompassing an aggregate population of 
over 185 million people and address more than 775 million channel pops. The 
Company holds one or more Wireless Licenses in numerous markets which allow 
it to provide Wireless Fiber services over four or more channels in such 
markets. The Company believes that the utilization of multiple 38 GHz 
channels in a single licensed area provides it with advantages over 38 GHz 
service providers that possess fewer channels, by allowing it to densely 
deploy its 38 GHz services and build out city-wide networks of broadband 
capacity. 

    The 38 GHz portion of the radio spectrum has characteristics well suited 
for the provision of local telecommunications services, including: 

    Rapid Deployment of Alternative Local Infrastructure.  38 GHz technology 
generally can be deployed considerably more rapidly than wireline (because of 
permit procedures and construction time required for wireline buildout) and 
many other wireless technologies (because of their infrastructure 
requirements and, in many instances, the need to follow FCC frequency 
coordination procedures in connection with wireless facilities).



                                                7
<PAGE>

    Broad Bandwidth.  The total amount of bandwidth for each 38 GHz channel 
is 100 MHz, which supports full broadband capability. For example, one 100 
MHz 38 GHz channel can support transmission capacity of one DS-3 at 45 Mbps 
which can transfer data at a rate that is over 1,500 times the rate of the 
fastest dial-up modem currently in general use (28.8 Kbps) and over 350 times 
the rate of the fastest ISDN line currently in general use (128 Kbps). Data 
transfer rates of a 38 GHz DS-3 channel even exceed the data transfer rates 
of cable modems (30 Mbps).  Further, it is anticipated that the Company's 
deployment of multi point facilities, planned to begin this year, will allow 
the Company's services to support one OC3 of capacity at 155 Mbps, which 
represents data transfer rates that are three times faster than those 
provided by currently deployed point-to-point technology.   The broadband 
capacity of 38 GHz provides improved speed and quality in transmissions, as 
compared to transmissions that are carried over a "last mile" consisting of 
copper wire. In addition to accommodating standard voice and data 
requirements, data transmission rates of 45 Mbps and higher allow end users 
to receive full-motion video and 3-D graphics and to use highly interactive 
applications on the Internet and other networks.

    Ease of Installation.  The equipment used for point-to-point applications 
in 38 GHz (i.e., antennae, transceivers and digital interface units) is 
typically smaller, less obtrusive, less expensive, and uses less power than 
equipment used for similar applications at lower frequencies. These 
characteristics make it relatively easier to obtain the roof rights ("Roof 
Rights") required to install 38 GHz transceivers, and less costly to initiate 
38 GHz-based services as compared to most other wireless services. 

    Efficient Channel Reuse.  Certain characteristics of 38 GHz, including 
the effective range of its radio signal and the small amount of dispersion 
(i.e., scattering) of the radio beam as compared to the more dispersed radio 
beams produced at lower frequencies, allow for the reuse of bandwidth 
capacity in a licensed area. The ability to reuse capacity allows the 38 GHz 
license holder to densely deploy its 38 GHz services in a given geographic 
area, provide services to multiple customers over the same 38 GHz channel, 
and conserve bandwidth capacity, thereby enhancing the types of services that 
can be provided and increasing the number of customers to which such services 
can be provided. 

Business Strategy

    The Company's objective is to become the full-service telecommunications 
provider of choice to small and medium-sized business customers and a 
provider of high-quality alternative and broadband facilities to its Carrier 
Services customers. Key elements of the Company's strategy are to: 

    Expand Network Infrastructure.  The Company is creating an infrastructure 
on a city-by-city basis using its Wireless Fiber capabilities, switches and 
other telecommunications equipment acquired by the Company from equipment 
vendors and facilities leased from other carriers to originate and terminate 
traffic. Pursuant to its building-centric network plan, the Company is 
identifying strategically located sites in each metropolitan area where it 
provides service to serve as hubs for its network in that metropolitan area. 
These hub sites will be connected via Wireless Fiber links to end users. The 
Company believes that a limited number of hub sites (generally less than a 
dozen) in each metropolitan area will allow it to address more than 70% of 
its targeted buildings and to carry the majority of its customers' traffic on 
its own network instead of the higher cost facilities of other carriers. 

    Exploit First-to-Market Advantages.  The Company seeks to capitalize on 
the significant opportunities emerging in the industry as a result of the 
Telecommunications Act of 1996 (the "Telecommunications Act") by exploiting a 
"first-to-market" advantage as one of the few holders of 38 GHz licenses with 
an established operating and management infrastructure. The Company believes 
that its early entrance into its markets provides it with advantages over 
many potential competitors by allowing it to: (i) establish a customer base 
prior to widespread competition from other CLECs; (ii) develop a proven, 
reliable network infrastructure using its own switching and transmission 
capabilities ahead of many other CLECs; (iii) develop pioneering expertise in 
the utilization of 38 GHz for the delivery of telecommunications and 
multimedia services and the design and management of 38 GHz-based networks; 
and (iv) acquire Roof Rights to place its 38 GHz antennae on a large number 
of buildings on favorable terms and in advance of other wireless service 
providers. 

    Focus on Small and Medium-Sized Business Customers.  The Company believes 
there exists a substantial opportunity to attract a base of small and 
medium-sized business customers by providing superior customer service and 
sales support. The customer base initially targeted by the Company consists 
of businesses typically located in buildings 

                                      8

<PAGE>

that have more than 100,000 square feet of commercial space and which, in 
many instances, are not served by fiber facilities provided by CLECs or 
competitive access providers ("CAPs"). The Company estimates that there are 
more than 8,000 buildings in this target group, populated by approximately 
9.7 million workers using more than 2.1 million phone lines. Over time, the 
Company intends to expand its target customer base to include the majority of 
small and medium-sized businesses in the metropolitan areas covered by the 
Wireless Licenses, which the Company estimates contain approximately 60% of 
all such businesses in the United States and represent a market opportunity 
in excess of $30 billion per year. 

    Market Wireless Fiber to Other Carriers.  The Company markets its Carrier 
Services to other carriers such as the RBOCs and other local exchange 
carriers ("LECs"), interexchange carriers ("IXCs"), other CAPs and CLECs, 
providers of personal communications services ("PCS") and cellular and 
specialized mobile radio services ("CMRS") providers. The Company believes 
that its Carrier Services present an attractive, economical method for 
telecommunications service providers to add a high-capacity extension to 
their own networks and service territories, especially as they seek to 
rapidly penetrate new markets opening as a result of the Telecommunications 
Act. The Company's Carrier Services can also provide cost-efficient route 
diversity where network reliability concerns require multiple 
telecommunications paths. 

    Since the commercial introduction of the Company's Carrier Services in 
October 1995, the number of carrier customers has increased significantly. 
Such customers include Ameritech Cellular Services, AT&T Wireless, Bell 
Atlantic/NYNEX Mobile, Brooks Fiber, Cellular One, PrimeCo Personal 
Communications, Siemens Stromberg-Carlson, Teleport Communications Group and 
Western Wireless. In addition, the Company has entered into multi-year master 
service agreements with American Communications Services, Electric Lightwave, 
IntelCom, MCI Communications and Pacific Bell. These agreements establish the 
framework under which such companies may effect the integration of Wireless 
Fiber services into their own telecommunications networks. The Company is in 
the process of negotiating additional master service agreements with other 
large telecommunications providers and has offered to enter into co-exclusive 
multi-region network usage agreements with one or more such providers. 

    Market Wireless Fiber Services as a Solution to Growing Capacity 
Shortages.  The Company believes that demand for its Wireless Fiber-based 
CLEC and Carrier Services will grow because of the expanding volume of data 
communications traffic resulting from increasing Internet usage and other 
high-volume data transmission requirements. This type of traffic increasingly 
requires high-capacity, end-to-end networks that are often difficult to 
provide economically with older RBOC and LEC infrastructure. 

    Provide Information and Content Services.  The Company believes that the 
ability to deliver information and other content will become an increasingly 
important factor in the choice of a telecommunications provider by businesses 
as competition increases and the markets covered by the Wireless Licenses 
mature. Accordingly, the Company actively seeks opportunities to utilize its 
information and content assets and services to enhance the marketability of 
the Company's telecommunications services. 

Development of Core Assets

    The Company believes that in order to effectively compete with incumbent 
LECs and other telecommunications service providers in its target markets, it 
must develop a core group of assets, capabilities and resources. The Company 
has made substantial progress in acquiring and developing these core assets, 
which include: 

    Transmission and Switching Facilities.  In October 1996, the Company 
initiated local switched services in New York City, utilizing its first 5ESS 
switch, purchased from Lucent Technologies, Inc. ("Lucent"), and facilities 
leased from NYNEX. Since that time, the Company has initiated local switched 
services in Boston, Chicago, Dallas, Fort Worth, Los Angeles, Newark, San 
Diego and Washington, D.C. During the next three years, the Company intends 
to install Lucent switches to serve most of its major markets. The Company 
has the necessary Roof Rights to install its Wireless Fiber transmission 
facilities on more than 1,900 buildings in its licensed areas. The Company 
also has developed business and operational support and network monitoring 
and management systems that will ensure the efficient use of its networks and 
provide network reliability and transmission quality equivalent to that 
provided by fiber-optic networks. The Company maintains a network operations 
center ("NOC"), which is operating 24 hours a day, 7 days a week, and is 
currently building a national field service force.


                                         9

<PAGE>

    In October 1997, the Company purchased (the "US ONE Asset Acquisition and 
Financing") from US ONE Communications Corp. and its subsidiaries, entities 
in bankruptcy, 12 Lucent switches, leased fiber-optic capacity in the New 
York metropolitan area and certain related assets for a purchase price of 
approximately $81.25 million in the form of (i) $61.25 million cash, paid at 
the closing of the US One Asset Acquisition and Financing and (ii) $20 
million, to be paid on the effective date of US ONE's confirmed plan of 
reorganization in its pending Chapter 11 bankruptcy case, in either cash or 
shares of the Company's common stock, in the Company's discretion.  The 
Company believes that the US ONE Asset Acquisition and Financing will allow 
the Company to accelerate the city-by-city rollout of its Wireless Fiber and 
switch based infrastructure, although there can be on assurance of this.  See 
"Description of Certain Indebtedness and Preferred Stock" for a description 
of the $62 million financing utilized by the Company in the US ONE Asset 
Acquisition and Financing.

    The Company recently entered into an agreement with a manufacturer and is 
negotiating with another alternative manufacturer for the initial development 
and deployment of equipment for use in local digital multi point 38 GHz  
networks.  A multi point network, also known as a point-to-multi point or a 
multiple point-to-point network, enables a single radio and antenna at a hub 
location to send and receive unique transmissions to and from many remote 
radios located within a cluster of buildings.  The Company believes that the 
implementation of multi point network architecture will provide it with (i) 
substantially reduced network deployment costs, (ii) more efficient spectrum 
utilization and reduced operating and installation costs and (iii) an 
improved ability to tailor spectrum allocation to address specific customer 
requirements (i.e., "bandwidth on demand").  The Company anticipates initial 
deployment of multi point technology during the fourth quarter of 1997 and 
general deployment of this technology during 1998.

    State Authorizations.  The Company has obtained authorization to operate 
as a CLEC in 28 states and the District of Columbia and is in the process of 
seeking authorization to operate as a CLEC in a number of additional 
jurisdictions. The Company is authorized to provide its local access and 
other Carrier Services as a CAP in 37 states and the District of Columbia and 
has applications pending for such authorizations in a number of additional 
jurisdictions. 

    Sales and Customer Support Organizations.  The Company is
expending a significant amount of time and capital to build a
dedicated, responsive sales and customer support organization in order
to ensure that the people and systems necessary to achieve customer
satisfaction keep pace with a growing customer base. The Company has a
direct sales organization for its CLEC services, currently consisting
of approximately 400 people located in 16 major markets, and a Carrier
Services sales group, currently consisting of approximately 40 people. 

    Information Systems.  The Company is investing significant capital
developing state-of-the-art information systems platforms directed
toward the accurate and flexible handling of the billing and customer
satisfaction requirements of a diverse customer base purchasing a
variety of telecommunications services. The Company believes that its
information systems allow it to provide customers with a level of
service and responsiveness that many other telecommunications services
providers do not offer and that such level of service will become a key
factor in customers' choice of telecommunications services providers as
the market matures. 

    Experienced Management and Operating Personnel.  The Company has
assembled a management team and hired operating personnel experienced
in all areas of telecommunications operations, including more than 250
former officers and employees of MCI Communications and Sprint
Corporation, as well as officers and employees from other established
telecommunications companies. The Company plans to hire additional
experienced telecommunications marketing and operations personnel as
appropriate. 

Other Businesses

    The Company has historically generated a significant portion of its 
revenues from the resale of long distance services to residential customers. 
As part of its CLEC service offerings, the Company is focusing on the sale of 
long distance services to small and medium-sized businesses and is not 
currently marketing such services to residential customers on an active basis.

    Prior to the Company's entry into the telecommunications industry, it 
marketed and distributed consumer products, including personal care and bath 
and beauty products, through a nonstrategic subsidiary. That subsidiary 
continues to sell such products, primarily to large retailers, mass 
merchandisers, discount stores, department stores, 

                                      10

national and regional drug store chains and other regional retail chains.  
The Company expects to divest itself of this subsidiary during the next 9 to 
12 months.

Corporate Information

    The Company was incorporated under the laws of the State of Delaware in 
September 1990, its principal office is located at 230 Park Avenue, New York, 
New York 10169 and its telephone number is (212) 584-4000.

                             of such holder's business and that such

                            approximately $820.9 million of indebtedness,
                            $561.1 million of which would have been senior
                            indebtedness and $197.5 million of which would

Restrictive Covenants .    The Indenture restricts the incurrence of
                           additional debt by the Company, the issuance
                           of debt and preferred stock by the Company's
                           subsidiaries, dividends on and redemptions of
                           capital stock of the Company, the redemption
                           of certain subordinated obligations of the
                           Company, the sale of assets and subsidiaries'
                           stock and transactions with affiliates. The
                           Indenture also prohibits certain restrictions
                           on distributions from subsidiaries and
                           restricts the Company from consolidating or
                           merging with or transferring all or
                           substantially all of its assets to another
                           person. However, all of these restrictions and
                           prohibitions are subject to a number of
                           important qualifications, including the
                           ability of the Company to designate certain
                           subsidiaries as unrestricted subsidiaries.

(1) Gives effect to (a) the acquisition of Milliwave Limited Partnership 
    ("Milliwave Acquisition") completed in January 1997, (b) an institutional 
    private placement of $100 million of Units, consisting of preferred stock 
    and warrants, completed in February 1997 ("Preferred Stock Placement"), 
    (c) a private placement in March 1997 ("March 1997 Debt Placement") of 
    $100 million 141/2 Senior Deferred Interest Notes Due 2005 of the Company 
    ("1997 Senior Notes") and $200 million 121/2% Guaranteed Senior Secured 
    Notes Due 2004 of WinStar Equipment Corp. ("WEC"), a wholly owned 
    subsidiary of the Company ("WEC Notes"), (d) a private placement in August 
    1997 ("August 1997 Debt Placement") by WinStar Equipment II Corp., a 
    wholly-owned subsidiary of the Company ("WEC II"), of $50.0 million 
    aggregate principal amount of its 121/2% Guaranteed Senior Secured Notes 
    Due 2004 (the "WEC II Notes" and, together with the WEC Notes and 1997 
    Senior Notes, the "1997 Notes"), (e) the October 1997 Debt Placement and 
    (f) the US ONE Asset Acquisition and Financing, each as if they occurred 
    as of the beginning of the respective period.  Interest expense has been 
    adjusted to include approximately $31.0 million and $72.5 million of 
    interest on such debt and amortization of debt offering costs and other 
    related fees in the nine months ended September 30, 1997 and the year 
    ended December 31, 1996, respectively, but not to include interest income 
    earned on additional available cash. Since the Milliwave Acquisition was 
    completed on January 2, 1997, its operations are reflected in the 
    historical results of the Company for the nine month period ended 
    September 30, 1997. See "Description of Certain Indebtedness and Preferred 
    Stock."  Depreciation expense has been adjusted to include approximately 
    $4.8 million and $6.4 million, respectively, of depreciation on certain of 
    the assets acquired in the US ONE Asset Acquisition and Financing, 
    assuming straight line depreciation over the expected useful lives of the 
    assets which will ultimately be placed in service.

(2) Such loss or income is from the operations of Global Products, the 
    Company's consumer products subsidiary. On May 13, 1997, a formal plan of 
    disposition for Global Products was approved by the Company's Board of 
    Directors, and it is anticipated that the disposition will be completed 
    within the next 12 months. The disposition of Global Products has been 
    accounted for as a discontinued operation and, accordingly, its net assets 
    have been segregated from continuing operations in the balance sheet data, 
    and its operating results through September 30, 1997 are segregated and 
    reported as discontinued operations in the statement of operations data. 

(3) For the year ended February 28, 1995, the ten months ended December 31, 
    1995, the year ended December 31, 1996 and the nine months ended September 
    30, 1996 and 1997, earnings from continuing operations were insufficient 
    to cover combined fixed charges and preferred stock dividends by $7,288,000,
    $16,310,000, $83,033,000, $49,411,000 and $169,172,000, respectively. On
    a pro forma basis, giving effect to the items described in footnote 1 above,
    earnings from continuing operations were insufficient to cover combined 
    fixed charges and preferred stock dividends by $205,655,000 and 
    $176,078,000 for the nine months ended September 30, 1997 and the year 
    ended December 31, 1996, respectively.  Fixed charges consist of interest 
    charges and amortization of debt expense and discount or premium related 
    to indebtedness, whether expensed or capitalized, and that portion of rent 
    expense that the Company believes to be representative of interest. 

(4) Gives effect to the October 1997 Debt Placement and the US ONE Asset 
    Acquisition and Financing, as if each occurred at September 30, 1997.

                                     RISK FACTORS

    The New Notes offered hereby contain the same terms and conditions as the 
Old Notes and, accordingly, involve a high degree of risk.  Each prospective 
investor should carefully consider the following risk factors relating to 
both the Old Notes and the New Notes.  This Prospectus contains 
forward-looking statements which involve risks and uncertainties.  The 
Company's actual results may differ significantly from the results discussed 
in the forward-looking statements.  Factors that might cause such differences 
include, but are not limited to, the following risk factors:

HISTORICAL AND ANTICIPATED FUTURE NET AND OPERATING LOSSES AND NEGATIVE EBITDA

    The Company has incurred significant operating and net losses 
attributable in substantial part to the development of its telecommunications 
businesses. The Company historically has had net losses and negative EBITDA, 
including net losses and negative EBITDA of approximately $15.9 million and 
$9.0 million, respectively, for the ten months ended December 31, 1995, $83.7 
million and $49.6 million, respectively, for the year ended December 31, 1996 
and $166.1 million and $108.8 million, respectively, for the nine months 
ended September 30, 1997. The Company has been offering local access and 
other Carrier Services only since December 1994, and local exchange services 
as a CLEC only since April 1996, and has made and is making significant 
expenditures in the development of its local telecommunications operations, 
including expenditures associated with establishing an operating 
infrastructure and introducing and marketing its telecommunications services. 
The Company expects to continue to experience significant and increasing 
operating losses, net losses and total and per share amounts of net loss, 
along with decreasing net current assets, and to generate increasingly 
negative EBITDA while it seeks to establish a sufficient revenue-generating 
customer base and build its network infrastructure so that it can provide 
services over its own facilities. As a result of increased expenses, 
principally relating to an increase in the number of employees in connection 
with the rollout of CLEC services and expenses relating to the servicing of 
debt, there will continue to be substantial increases in the Company's net 
loss, operating loss and negative EBITDA. There can be no assurance that the 
Company will achieve or sustain positive EBITDA or profitability or at any 
time have sufficient financial resources to make principal and interest 
payments on its outstanding debt, including the Notes offered hereby. 

SUBSTANTIAL INDEBTEDNESS; ABILITY TO SERVICE INDEBTEDNESS

    At September 30, 1997, on a pro forma basis giving effect to the 
consummation of the October 1997 Debt Placement and the US ONE Asset 
Acquisition and Financing, the Company would have had, on a consolidated 
basis, approximately $856.0 million of indebtedness, including capitalized 
lease obligations.  The accrual of interest on the 1997 Senior Notes and the 
US ONE Asset Acquisition and Financing and the accretion of original issue 
discount on the Convertible Notes and the Company's outstanding 14% Senior 
Discount Notes due 2005 (the "1995 Senior Notes" and, together with the 
Convertible Notes, the "1995 Notes) will significantly increase the Company's 
liabilities (except to the extent that the Convertible Notes are converted 
into the Company's Common Stock). The Company has significant indebtedness 
and interest expense as a result of the issuance of the Notes, 1995 Notes, 
1997 Notes and the consummation of the US ONE Asset Acquisition and 
Financing.  The Company also may need to incur additional indebtedness in the 
future. The indentures pursuant to which the 1995 Notes, 1997 Notes and Notes 
were issued (collectively, the "Indentures") limit, but do not prohibit, the 
incurrence of additional indebtedness by the Company and its subsidiaries. 
Additionally, the Indentures do not limit the amount of indebtedness that may 
be incurred by the Company's new media and consumer products subsidiaries. 

    The level of the Company's indebtedness could have important 
consequences, including the following: (i) the combined debt service 
requirements of the 1995 Notes, 1997 Notes and US ONE Asset Acquisition and 
Financing could make it more difficult for the Company to make payments on 
the Notes offered hereby; (ii) the ability of the Company to obtain any 
necessary financing in the future for working capital, capital expenditures, 
debt service requirements or other purposes may be limited; (iii) a 
substantial portion of the Company's cash flow from operations, if any, must 
be dedicated to the payment of principal and interest on its indebtedness and 
other obligations and will not be available for use in the Company's 
business; (iv) the Company's level of indebtedness could limit its 
flexibility in planning for, or reacting to changes in, its business; (v) the 
Company is more highly leveraged than many of its competitors, which may 
place it at a competitive disadvantage; and (vi) the Company's high degree of 
indebtedness would make it more vulnerable in the event of a downturn in its 
business or if operating cash flow does not significantly increase.

HOLDING COMPANY STRUCTURE; RANKING OF THE NOTES; UNSECURED INDEBTEDNESS

    The Company is a holding company and its only material assets consist of 
the common stock of its operating subsidiaries and the proceeds raised from 
certain private placements of equity and debt securities, all of which the 
Company has loaned or contributed, or intends to loan or contribute, to its 
subsidiaries. The Company may have to rely upon dividends and other payments 
from its subsidiaries to generate the funds necessary to pay the principal of 
and interest on the Notes. The subsidiaries, however, are legally distinct 
from the Company and have no obligation, contingent or otherwise, to pay 
amounts due pursuant to the Notes or to make funds available for such 
payment. The Company's subsidiaries have not guaranteed the Notes. The 
ability of the Company's subsidiaries to make such dividends and other 
payments to the Company is subject to, among other things, the availability 
of funds, the terms of such subsidiaries' indebtedness and applicable state 
laws. See "Description of Certain Indebtedness and Preferred Stock." Claims 
of creditors of the Company's subsidiaries, including trade creditors, will 
generally have priority as to the assets of such subsidiaries over the claims 
of the Company and the holders of the Company's indebtedness, including the 
Notes. Accordingly, the Notes are effectively subordinated to all liabilities 
(including trade payables) of the subsidiaries of the Company. At September 
30, 1997, the subsidiaries of the Company had approximately $339.7 million of 
liabilities (excluding intercompany payables to the Company and each other), 
including $293.4 million of indebtedness.

    The Notes are unsecured indebtedness of the Company. At September 30, 
1997, after giving effect to the October 1997 Debt Placement and US ONE Asset 
Acquisition and Financing, the Company on a consolidated basis had an 
aggregate of approximately $856.0 million of indebtedness, including 
capitalized lease obligations, $355.7 million of which was secured by liens 
on certain of the Company's assets. In the event such secured indebtedness 
goes into default and the holders thereof foreclose on the collateral, the 
holders of secured indebtedness will be entitled to payment out of the 
proceeds of their collateral prior to any holders of general unsecured 
indebtedness, including the Notes, notwithstanding the existence of any event 
of default with respect to the Notes. 

    In addition, the Notes are subordinated to all senior indebtedness of the 
Company, including indebtedness under the 1995 Senior Notes, the 1997 Senior 
Notes, the guarantee by the Company of the WEC Notes (the "WEC Note 
Guarantee"), the Company's guarantee of the WEC II Notes (the "WEC II Note 
Guarantee" and, together with the WEC Note Guarantee, the "Equipment Note 
Guarantees") and the Company's guarantees under the Equipment Lease 
Financing, the Finova Lease Financing, the Revolving Credit Facility and the 
CIT Credit Facility (all as defined herein). Therefore, in the event of a 
bankruptcy, liquidation or reorganization of the Company, the assets of the 
Company will be available to pay obligations on the Notes only after all 
senior indebtedness has been paid in full and there may not be sufficient 
assets remaining to pay amounts due on the Notes. At September 30, 1997, 
after giving effect to the October 1997 Debt Placement, and the US ONE Asset 
Acquisition and Financing, the amount of outstanding senior indebtedness of 
the Company was approximately $596.3 million.  

NEED TO REFINANCE SUBSTANTIAL AMOUNT OF INDEBTEDNESS TO REPAY NOTES AT MATURITY

    The Notes mature in March 2007. If the Company does not have cash flow 
from operations with which to pay the Notes, the Company would be forced to 
raise the cash to pay the Notes through equity offerings or additional debt 
financings. The Company's ability to raise additional debt financing to repay 
the Notes is severely restricted under the terms of the Indentures, which may 
require the Company to refinance the 1995 Notes and the 1997 Senior Notes, 
WEC Notes and WEC II Notes prior to or simultaneously with any refinancing of 
the Notes. Accordingly, the Company may be forced to refinance a substantial 
amount of other indebtedness in order for the Notes to be paid when due. 
There can be no assurance that the Company will be able to refinance any or 
all of such indebtedness at such time. 

RISKS RELATED TO CLEC STRATEGY; ANTICIPATED INITIAL NEGATIVE OPERATING 
MARGINS IN CLEC BUSINESS

    The Company is pursuing an accelerated strategy to enter the local 
exchange services market as a CLEC in the metropolitan areas in which it has 
Wireless Licenses and to develop and obtain the facilities necessary to 
provide its own switched local exchange services. The Company has limited 
experience providing local exchange services and there can be no assurance 
that the Company's CLEC strategy will be successful. In addition, local 
exchange service providers have never utilized 38 GHz wireless-based systems 
as a significant segment of their local exchange services facilities and 
there can be no assurance that the Company will be successful in implementing 
its Wireless Fiber-based system. The Company's CLEC strategy is subject to 
risks relating to: the receipt of necessary regulatory approvals; the 

                                       21


<PAGE>


negotiation and implementation of resale agreements with other local service 
providers; the negotiation and implementation of interconnection agreements 
with RBOCs and other incumbent LECs; the failure of LECs and RBOCs to honor 
the letter and spirit of consummated interconnection agreements; the ability 
of third-party equipment providers and installation and maintenance 
contractors to meet the Company's rollout schedule; the recruitment of 
additional personnel in a timely manner, so as to be able to attract and 
service new customers but not incur excessive personnel costs in advance of 
the rollout; the Company's ability to attract and retain new customers 
through delivery of high-quality services; the potential adverse reaction to 
the Company's services by the Company's carrier customers, which may view the 
Company as a competitor; and the Company's ability to manage the simultaneous 
implementation of its plan in multiple markets. In addition, the Company is 
subject to the risk of unforeseen problems inherent in being a new entrant in 
a rapidly evolving industry. 

    Historically, almost all of the Company's telecommunications revenues 
have been derived from the resale of long distance services to residential 
customers. As part of its CLEC strategy, the Company is marketing its long 
distance services to small and medium-sized businesses and is no longer 
actively marketing such services to residential customers. As a result, 
revenues from the provision of long distance services to residential 
customers have begun and are expected to continue to substantially decline 
through attrition of the Company's long distance residential customer base. 

    Although the Company's initial implementation of its CLEC strategy 
entails the resale of the facilities and services of other service providers, 
which itself is dependent on the negotiation and implementation of 
satisfactory resale arrangements, the Company's CLEC strategy will require 
significant capital investment related to the purchase and installation of 
numerous switches and the interconnection of these facilities to customers' 
buildings and LEC and CLEC local networks, including the installation of 
Wireless Fiber links and the buildout of other facility infrastructure, in 
advance of generating material revenues. 

    As the Company rolls out its CLEC operations, it will experience negative 
operating margins while it develops its facilities. After initial rollout of 
its CLEC services in a particular city, the Company expects operating margins 
for such operations to improve only when and if: (i) sales efforts result in 
sufficiently increased volumes of traffic; (ii) the Company has installed a 
switch and a sufficient number of Wireless Fiber links so that a substantial 
portion of the Company's traffic in that city can be originated and 
terminated over the Company's Wireless Fiber facilities instead of LEC or 
other CLEC facilities; and (iii) higher margin-enhanced services are sought 
by, provided to and accepted by customers. While the Company believes that 
the unbundling and resale of LEC services and the implementation of local 
telephone number portability (which will permit customers to retain their 
telephone numbers when switching carriers), which are mandated by the 
Telecommunications Act, will reduce the Company's costs of providing local 
exchange services and facilitate the marketing of such services, there can be 
no assurance that the Company's CLEC operations will become profitable due 
to, among other factors, lack of customer demand, competition from other 
CLECs and pricing pressure from the LECs and other CLECs. The Company's 
failure to implement its CLEC strategy successfully would have a material 
adverse effect on the operations of the Company and the ability of the 
Company and its subsidiaries to make principal and interest payments on their 
outstanding debt, including the Notes.

NEGATIVE OPERATING MARGINS IN THE INITIAL PROVISION OF WIRELESS FIBER-BASED 
CARRIER SERVICES

    The Company has experienced negative operating margins in connection with 
the development and initial provision of its Wireless Fiber-based Carrier 
Services and expects to continue to experience negative operating margins 
until it develops a sufficient revenue-generating customer base for such 
services. In order to demonstrate the efficacy of Wireless Fiber, the Company 
often provides complimentary service on a trial basis for a limited period. 
The Company expects to improve operating margins in the provision of its 
Carrier Services over time by: (i) continuing to obtain appropriate Roof 
Rights; (ii) acquiring and retaining an adequate customer base; (iii) placing 
telecommunications traffic of new customers and additional telecommunications 
traffic of existing customers across installed Wireless Fiber links; and (iv) 
inducing providers of telecommunications services to utilize and market the 
Company's Wireless Fiber services as part of their own networks, systems and 
services, thereby reducing the Company's related marketing costs. If the 
Company fails to accomplish any of the foregoing, particularly acquiring and 
retaining an adequate customer base, it will not be able to improve the 
operating margins of its Carrier Services business. There can be no assurance 
that the Company will be able to achieve or sustain positive operating 
margins. Failure to achieve positive operating margins 

                                       22


<PAGE>


would have a material adverse effect on the operations of the Company and the 
ability of the Company and its subsidiaries to make principal and interest 
payments on their outstanding debt, including the Notes.

RISKS ASSOCIATED WITH RAPID EXPANSION AND ACQUISITIONS

    The Company intends to pursue a strategy of aggressive and rapid growth, 
including the accelerated rollout of its CLEC services, acquisitions of 
businesses and assets, including additional spectrum licenses, continued 
marketing of its Carrier Services, and the hiring of additional management, 
technical and marketing personnel, all of which will result in significantly 
higher operating expenses. Rapid expansion of the Company's operations may 
place a significant strain on the Company's management, financial and other 
resources. The Company's ability to manage future growth, should it occur, 
will depend upon its ability to monitor operations, control costs, maintain 
effective quality controls and significantly expand the Company's internal 
management, technical, information and accounting systems. Any failure to 
expand these areas and to implement and improve such systems, procedures and 
controls in an efficient manner at a pace consistent with the growth of the 
Company's business could have a material adverse effect on the business, 
financial condition and results of operations of the Company and the ability 
of the Company and its subsidiaries to make principal and interest payments 
on their outstanding debt, including the Notes. As part of its strategy, the 
Company may acquire complementary assets or businesses. The pursuit of 
acquisition opportunities will place significant demands on the time and 
attention of the Company's senior management and will involve considerable 
financial and other costs with respect to identifying and investigating 
acquisition candidates, negotiating acquisition agreements and integrating 
the acquired businesses with the Company's existing operations. Employees and 
customers of acquired businesses may sever their relationship with such 
businesses during or after the acquisition. There can be no assurance that 
the Company will be able to successfully consummate any acquisitions or 
integrate any business or assets which it may acquire into its operations.

COMPETITION

    The Company is subject to intense competition in each of the areas in 
which it operates. Many of the Company's competitors have longer-standing 
relationships with customers and suppliers in their respective industries, 
greater name recognition and significantly greater financial, technical and 
marketing resources than the Company. Further, sales of the Company's Carrier 
Services are typically made to other telecommunications providers that 
compete or may compete in the future with the Company. 

    LOCAL TELECOMMUNICATIONS MARKET.  The local telecommunications market is 
intensely competitive for new entrants and currently is dominated by the 
RBOCs and other LECs. The LECs have long-standing relationships with their 
customers, have the ability to subsidize competitive services with revenues 
from a variety of other services and benefit from existing state and federal 
regulations that currently favor the LECs over the Company in certain 
respects. In addition to competition from the LECs, the Company also faces 
competition from a growing number of new market entrants, such as other CLECs 
and CAPs. The Company also may face competition in the provision of local 
telecommunications services from cable companies, electric utilities, LECs 
operating outside their current local service areas and IXCs. Moreover, the 
consolidation of telecommunications companies and the formation of strategic 
alliances within the telecommunications industry, which have accelerated, 
could give rise to significant new or stronger competitors. The Company 
currently also faces or anticipates facing competition from other entities 
which offer, or are licensed to offer, 38 GHz services and could face 
competition in certain aspects of its existing and proposed businesses from 
competitors providing wireless services in other portions of the radio 
spectrum (including 2 GHz, 18 GHz, 24 GHz, 28 GHz and 47 GHz, among others). 
The initial perceived success of the Company's business is also likely to 
encourage increased competition from other spectrum users. The Company's 
Internet services also face significant competition from, among others, cable 
television operators deploying cable modems that provide high-speed data 
transmission over existing coaxial cable television networks. As competition 
increases in the local telecommunications market, the Company anticipates 
that general pricing competition and pressures will increase significantly. 
The Company has not obtained significant market share in any of the areas 
where it offers its services, nor does it expect to do so given the size of 
its local telecommunications services markets, the intense competition 
therein and the diversity of customer requirements. There can be no assurance 
that the Company will be able to compete effectively in any of its markets. 

    LONG DISTANCE MARKET.  The long distance market has relatively 
insignificant barriers to entry, numerous entities competing for the same 
customers and a high (and increasing) average churn rate as customers 
frequently change

                                       23


<PAGE>


long distance providers in response to the offering of lower rates or 
promotional incentives by competitors. The Company competes for long distance 
customers with major IXCs, as well as other national and regional long 
distance carriers and resellers, many of whom own substantially all of their 
own facilities and are able to provide services at costs lower than the 
Company's current costs since the Company generally leases its access 
facilities. The Company believes that the RBOCs and CLECs also will become 
significant competitors in the long distance telecommunications industry. To 
maintain its competitive posture, the Company believes that it must be in a 
position to reduce its prices in order to meet reductions in rates, if any, 
by competitors. Any such reductions could adversely affect the Company. In 
addition, LECs have been obtaining additional pricing and regulatory 
flexibility. This may enable LECs to grant volume discounts to larger long 
distance companies, which also could put the Company's long distance business 
at a disadvantage in competing with larger providers. 

    NEW MEDIA BUSINESS.  The industry in which the Company's new media 
subsidiary competes consists of a very large number of entities producing, 
owning or controlling news, sports, entertainment, educational and 
informational content and services, including telecommunications companies, 
television broadcast companies, sports franchises, film and television 
studios, record companies, newspaper and magazine publishing companies, 
universities and on-line computer services. Competition is intense for timely 
and highly marketable or usable information and entertainment content. Almost 
all of the entities with which the Company's new media subsidiary competes 
have significantly greater presence in the various media markets and greater 
resources than the Company, including existing content libraries, financial 
resources, personnel and existing distribution channels. There can be no 
assurance that the Company will be able to compete successfully in the 
emerging new media industry.

SIGNIFICANT CAPITAL REQUIREMENTS

    The expansion of the Company's telecommunications operations and the 
continued funding of operating expenses will require substantial capital 
investment. Additionally, as part of its strategy, the Company may seek to 
acquire complementary assets or businesses (including additional spectrum 
licenses, by auction or otherwise), which also could require substantial 
capital investment. The Company's decision to accelerate the development of 
its CLEC operations in response to the Telecommunications Act has 
substantially increased the Company's near-term capital expenditure 
requirements. The amount of capital required to execute the Company's business 
plan is a function of the speed at which its plan is executed. Management 
anticipates, based on current plans and assumptions relating to its 
operations, that the Company's existing financial resources and additional 
financing arrangements which the Company believes are readily available, will 
be sufficient to fund the Company's growth and operations for approximately 
24 to 30 months from the date of this Prospectus.  In the event the Company's 
plans or assumptions change or prove to be inaccurate, or if the Company 
consummates any acquisitions of businesses or assets (including additional 
spectrum licenses, by auction or otherwise), or if the Company fails to 
secure additional equipment financing arrangements, if necessary, the Company 
may be required to seek additional sources of capital sooner than currently 
anticipated. Sources of additional capital may include public and private 
equity and debt financing, sales of nonstrategic assets and other financing 
arrangements. There can be no assurance that the Company will be able to 
obtain additional financing or, if such financing is available, that the 
Company will be able to obtain it on acceptable terms. Failure to obtain 
additional financing, if needed, could result in the delay or abandonment of 
some or all of the Company's development and expansion plans, which would 
have a material adverse effect on the Company's business and could adversely 
affect the ability of the Company and its subsidiaries to make principal and 
interest payments on their outstanding debt, including the Notes. 

GOVERNMENT REGULATION

    The Company's telecommunications services are subject to varying degrees 
of federal, state and local regulation. Generally, the FCC exercises 
jurisdiction over all telecommunications services providers to the extent 
such services involve the provision of jurisdictionally interstate or 
international telecommunications, including the resale of long distance 
services, the provision of local access services necessary to connect callers 
to long distance carriers and the use of electromagnetic spectrum (i.e., 
wireless services). With the passage of the Telecommunications Act, the FCC's 
jurisdiction has been extended to include certain issues that traditionally 
have been considered subject primarily to state regulation (e.g., number 
portability and carrier discrimination issues). The state regulatory 
commissions retain jurisdiction over the provision of telecommunications 
services to the extent such services involve the provision of 
jurisdictionally intrastate telecommunications in certain instances.

                                       24


<PAGE>


    The Telecommunications Act is intended to remove the formal barriers 
between the long distance and local telecommunications services markets, 
allowing service providers from each market (as well as providers of cable 
television and other services) to compete in all communications markets. The 
Telecommunications Act will permit the RBOCs eventually to compete in the 
provision of long distance services between local access transport areas 
("LATAs"). Additionally, the FCC is required to promulgate new regulations to 
address mandates contained in the Telecommunications Act, which will change 
the regulatory environment significantly. The Telecommunications Act 
generally requires LECs to provide competitors with interconnection and 
nondiscriminatory access to the LEC network on more favorable terms than have 
been available in the past. However, such interconnection and the terms 
thereof are subject to negotiations with each LEC, which may involve 
considerable delays and may not necessarily be obtained on terms and 
conditions that are acceptable to the Company. In such instances, although 
the Company may petition the proper regulatory agency to arbitrate disputed 
issues, there can be no assurance that the Company will be able to obtain 
acceptable interconnection agreements covering each of the market where it 
intends to offer services.

    As required by the Telecommunications Act, in August 1996, the FCC 
adopted new rules implementing the interconnection and resale provisions of 
the Telecommunications Act (the "Interconnection Order"). These rules 
generally constitute a pro-competitive, national policy framework designed to 
remove or minimize the regulatory, economic and operational impediments to 
full competition for local services, including switched local exchange 
services. The United States Court of Appeals for the Eighth Circuit stayed 
the Interconnection Order in October 1996 and, in July 1997, invalidated 
certain provisions of the Interconnection Order, including those provisions 
in which the FCC asserted jurisdiction over the pricing of interconnection 
elements and the "pick and choose" provisions for interconnectors to select 
discrete provisions of other carriers' interconnection agreements. Many 
states, however, continue to set the prices for interconnection, resale and 
unbundled network elements. In October, the Eighth Circuit issued a further 
decision with respect to the Interconnection Order that vacated the 
obligation of incumbent LECs, under certain circumstances, to provide 
combinations of network elements, rather than provide them individually.  The 
FCC has indicated its intention to appeal the Eighth Circuit's rulings to the 
United States Supreme Court.  The Company believes that the Eighth Circuit's 
rulings will not adversely affect its CLEC operations and may, in certain 
instances, positively affect the operations of its Carrier Services business. 
In addition, pursuant to the Telecommunications Act, the FCC recently 
promulgated regulations to, among other things, implement universal service 
reform, provide support for the provision of ubiquitous national telephone 
service and effect access charge reform to more explicitly align the access 
charges paid by long distance carriers to incumbent LECs to the actual cost 
of providing such services. In light of the continued litigation challenging 
the validity of the Telecommunications Act and the regulations promulgated 
thereunder by the FCC, as well as efforts before Congress to seek 
modification of provisions of the Telecommunications Act, the Company is 
unable to predict with specificity what effect the Telecommunications Act or 
recently promulgated FCC regulations will have on the telecommunications 
industry in general and on the Company in particular. No assurance can be 
given that any regulation will broaden the opportunities available to the 
Company or will not have a material adverse effect on the Company and its 
operations. Further, there can be no assurance that the Company will be able 
to comply with additional applicable laws, regulations and licensing 
requirements or have sufficient resources to take advantage of the 
opportunities which may arise from this dynamic regulatory environment.

    Providers of telecommunications services, including the major IXCs, 
RBOCs, CLECs and others, are coming under intensified regulatory scrutiny for 
activities by them or their agents which may result in unauthorized switching 
of customers from one service provider to another or, in other instances, 
unfairly  impeding customers seeking to switch providers. The FCC, the 
Federal Trade Commission and a number of state authorities are seeking to 
introduce more stringent regulation to curtail the intentional or erroneous 
switching of customers, which could include the imposition of fines, 
penalties and possible operating restrictions on entities which engage in 
unauthorized switching activities. In addition, the Telecommunications Act 
requires the FCC to prescribe regulations imposing procedures for verifying 
the switching of customers and additional remedies on behalf of carriers for 
unauthorized switching of their customers. The effects, if any, the adoption 
of any such regulations would have on the telecommunications industry and the 
business practices therein cannot be predicted. Statutes and regulations 
which are or may become applicable to the Company as it expands could require 
the Company to alter methods of operations, at costs which could be 
substantial, or otherwise limit the types of services it offers.

FINITE INITIAL TERM OF WIRELESS LICENSES; POTENTIAL LICENSE RENEWAL COSTS; 
FLUCTUATIONS IN THE VALUE OF WIRELESS LICENSES; TRANSFER OF CONTROL

    As described in the FCC's Report and Order and Second Notice of Proposed 
Rulemaking, released on November 3, 1997 (the "38 GHz Order"), the FCC's 
policy is to align the expiration dates of all 38 GHz licenses 

                                       25


<PAGE>


granted before August 1, 1996 such that they mature concurrently on February 
1, 2001. Licenses granted on or after August 1, 1996 have terms not to exceed 
ten years.  In each case, the licensee is entitled to an expectation of 
renewal if the Fee's buildout requirements are met.  While the Company 
believes that all of its Wireless Licenses will be renewed based upon FCC 
custom and practice establishing a presumption in favor of licensees that 
have complied with their regulatory obligations during the initial license 
period, there can be no assurance that any Wireless License will be renewed 
upon expiration of its initial term. 

    In the 38 GHz Order, the FCC also ruled that (i) it would impose no 
limits on the accumulation of licenses in the 38GHz band, (ii) the 39.5 - 
40.0 GHz portion of this band would not be reserved for use by satellite 
operations and that co-primary sharing of the 38 GHz band with satellite 
operators is not feasible, (iii) licensees should be permitted great 
flexibility in use of this spectrum, including use for point-to-multi point 
and mobile services, and (iv) currently unlicensed channels in the 38 GHz 
band will be auctioned.

    While the Company views the vast majority of the FCC's determinations in 
the 38 GHz Order as favorable to its operations and business plan, there can 
be no assurance that all or a portion of the 38 GHz Order will not be repealed 
or altered as a result of such proceedings.

    The Wireless Licenses are integral assets of the Company, the value of 
which will depend significantly upon the success of the Company's wireless 
telecommunications operations and the future direction of the wireless 
telecommunications segment of the telecommunications industry. The value of 
licenses to provide wireless services also may be affected by fluctuations in 
the level of supply and demand for such licenses and by valuations placed on 
such licenses in any future auction of such spectrum. Any assignment of a 
license or transfer of control by an entity holding a license is subject to 
certain limitations relating to the identity and qualifications of the 
transferee and requires prior FCC approval (and in some instances state 
regulatory approval as it relates to the provision of telecommunications 
services in that state), thereby possibly diminishing the value of the 
Wireless Licenses. 

    The Company has entered into agreements to acquire a number of additional 
38 GHz licenses.  The transfer of licenses issued by the FCC, including 38 
GHz licenses (as well as a change of control of entities holding licenses), 
is subject to the prior consent of the FCC, which consent generally turns on 
a number of factors including the identity, background and the legal and 
financial qualifications of the transferee and the satisfaction of certain 
other regulatory requirements.  In light of the foregoing, the newness of 
this service and possible revisions to the policies and regulations set forth 
in the 38 GHz Order as a result of the challenges thereto, the uncertainty of 
final regulations to be issued in connection with the NPRM, there can be no 
assurance that the FCC will approve all or any of the proposed acquisitions.

CHANGES IN TECHNOLOGY, SERVICES AND INDUSTRY STANDARDS

    The telecommunications industry has been characterized by rapid 
technological change, changing end-user requirements, frequent new service 
introductions and evolving industry standards. The Company believes that its 
future success will depend on its ability to anticipate or adapt to such 
changes and to offer, on a timely basis, services that meet these evolving 
industry standards. The extent to which competitors using existing or 
currently undeployed methods of delivery of local telecommunications services 
will compete with the Company's Wireless Fiber services cannot be 
anticipated. There can be no assurance that existing, proposed or as yet 
undeveloped technologies will not become dominant in the future and render 38 
GHz-based (and other spectrum-based) systems less profitable or less viable. 
For example, there are several existing technologies that may be able to 
allow the transmission of high bandwidth traffic over existing copper lines 
or unlicensed spectrum. There can be no assurance that the Company will have 
sufficient resources to make the investments necessary to acquire new 
technologies or to introduce new services that could compete with future 
technologies or that equipment held by the Company in inventory will not be 
rendered obsolete, any of which would have an adverse effect on the 
operations of the Company and the ability of the Company and its subsidiaries 
to make principal and interest payments on their outstanding debt, including 
the Notes.

CERTAIN FINANCIAL AND OPERATING RESTRICTIONS

    The indebtedness of the Company and the Indentures impose significant 
operating and financial restrictions on the Company, affecting, and in 
certain cases limiting, among other activities, the ability of the Company to 
incur additional indebtedness or create liens on its assets, pay dividends, 
sell assets, engage in mergers or acquisitions or make investments. Failure 
to comply with any such restrictions could limit the availability of 
borrowings or result in a default under the terms of any such indebtedness, 
and there can be no assurance that the Company will be able to comply with 
such restrictions. Moreover, these restrictions could limit the Company's 
ability to engage in certain business transactions which the Company may 
desire to consummate. The Company's inability to consummate any such 
transaction could have an adverse effect on the Company's operations and the 
ability of the Company and its subsidiaries to make principal and interest 
payments on their outstanding debt, including the Notes. See "Description of 
Certain Indebtedness and Preferred Stock." 

ORIGINAL ISSUE DISCOUNT; POSSIBLE UNFAVORABLE TAX AND OTHER LEGAL 
CONSEQUENCES FOR HOLDERS OF NOTES AND THE COMPANY

    As there will be no periodic payments in cash of interest on the Notes 
prior to September 2002, original issue discount (the difference between the 
stated redemption price at maturity and the issue price of the Notes) will 
accrue from the issue date of the Notes. Original issue discount must be 
included as interest income periodically in a United States noteholder's 
gross income for United States federal income tax purposes in advance of 
receipt of the cash payments to which the income is attributable. 

    Further, the Notes will be subject to the high yield discount obligation 
rules. Consequently, the Company will not be able to deduct the original 
issue discount attributable to the Notes until actually paid. As explained 
in, and subject to, the discussion under "Certain United States Federal 
Income Tax Consequences--Tax Consequences to U.S. Holders--Applicable High 
Yield Discount Rules," the Notes are subject to these rules because their 
yield to maturity equals or exceeds the Treasury-based interest rate in 
effect for the month of their issuance plus five percentage points. For 
mid-term debt instruments issued in October 1997, such Treasury-based 
interest rate plus five percentage points is 11.24%, compounded semiannually. 
Moreover, because the yield to maturity of the Notes exceeds a Treasury-based 
interest rate in effect for the month of their issuance plus six percentage 
points, a portion of the original issue discount attributable to the Notes 
will not be deductible at all. For mid-term debt instruments issued in 
October 1997, such Treasury-based interest rate plus six percentage points is 
12.24%, compounded semiannually. As a result of the application of these high 
yield discount rules, the Company's after tax cash flow might be less than if 
such original issue discount were deductible when accrued. See "Certain 
United States Federal Income Tax Considerations" for a more detailed 
discussion of the United States federal income tax consequences to holders of 
Notes regarding the purchase, ownership and disposition of such Notes. 

DEPENDENCE ON THIRD PARTIES FOR SERVICE AND MARKETING; POSSIBLE SERVICE 
INTERRUPTIONS AND EQUIPMENT FAILURES

    The Company's long distance resale business is dependent on utilizing the 
facilities of major IXCs to carry its customers' long distance telephone 
calls and, in many instances, especially during initial market penetrations, 
the Company's CLEC business will be dependent on the facilities of the LECs 
and other local exchange service providers to carry its customers' local 
telephone calls. The Company has an agreement with MCI that provide it with 
access to such carrier's networks and has entered or is entering into 
interconnect agreements with various LECs, and other CLECs, to access their 
local exchange facilities. Although the Company believes that it currently 
has sufficient access to long distance networks and will be able to obtain 
sufficient access to local exchange facilities, any increase in the rates or 
access fees charged by the owners of such facilities or their unwillingness 
to provide access to such facilities to the Company, as well as potential 
reticence of the LECs to honor appropriate provisioning and service intervals 
with respect to interconnection arrangements, could materially adversely 
affect the Company's operations. Failure to obtain continuing access to such 
networks and facilities could require the Company to significantly curtail or 
cease its operations and could have an adverse effect on the ability of the 
Company and its subsidiaries to make principal and interest payments on their 
outstanding debt, including the Notes. See "Description of Certain 
Indebtedness and Preferred Stock." Further, the Company's CLEC operations 
will rely to some extent upon network elements which the LECs must provide 
pursuant to the Telecommunications Act and the Interconnection Order. These 
facilities often use copper wire 

                                       27

<PAGE>


for "last mile" access to end users. To the extent that the Company relies 
upon LEC facilities that use copper wire, the Company may not be able to 
offer potential customers the benefits of Wireless Fiber with respect to high 
transmission capacity and quality. In addition, the Company's operations 
require that the networks leased by it, and any facilities which may be 
developed by the Company, operate on a continuous basis. It is not unusual 
for networks and switching facilities to experience periodic service 
interruptions and equipment failures. It is therefore possible that the 
networks and facilities utilized by the Company may from time to time 
experience service interruptions or equipment failures resulting in material 
delays which would adversely affect consumer confidence as well as the 
Company's business operations and reputation.

    The Company utilizes, in certain cases, third parties for marketing its 
Wireless Fiber services and maintaining its operational systems. The Company 
has entered into master service agreements with other telecommunications 
providers that allow those companies to utilize and resell the Company's 
Wireless Fiber services to their own customers. The Company also has an 
agreement with Lucent to provide field service for, and network monitoring 
of, the Company's Wireless Fiber facilities and another agreement with Lucent 
for the purchase by the Company of telecommunications switches and related 
equipment. The failure of any of these third parties to perform under their 
respective agreements or the loss of any of these agreements could have a 
material adverse effect on the Company's results of operations and its 
ability to service its customers. The Company has approached a number of 
major telecommunications service providers to solicit interest in entering 
into a multi-year, multi-region network transaction in which the Company 
would build and maintain a co-exclusive network utilizing Wireless Fiber for 
providing access to their customer base.  Although there can be no assurance 
that such a transaction will be entered into, the Company believes that such 
a transaction would be attractive to a number of these provides and is in 
various stages of discussions with them.

RELIANCE ON EQUIPMENT SUPPLIERS

    The Company currently purchases substantially all of its wireless 
telecommunications equipment, including transceivers and network monitoring 
equipment, from a single supplier and its switches and related equipment from 
a single supplier even though, in each case, there are other manufacturers of 
such equipment. Any reduction or interruption in supply from its suppliers 
could have a material adverse effect on the Company until sufficient 
alternative supply sources are established. The Company does not manufacture, 
nor does it have the capability to manufacture, any of its telecommunications 
equipment. Although there are other manufacturers who have, or are 
developing, equipment that would satisfy the Company's needs, there can be no 
assurance that the Company would be able to replace its current primary 
suppliers on commercially reasonable terms. In addition, as no industry 
standard or uniform protocol currently exists for 38 GHz equipment, a single 
manufacturer's equipment must be used in establishing each wireless link.

LINE OF SIGHT; DISTANCE LIMITATIONS IMPOSED BY RAINFALL CONDITIONS IN CERTAIN 
GEOGRAPHIC AREAS; ROOF RIGHTS

    In order to provide quality transmission, Wireless Fiber services require 
an unobstructed line of sight between two transceivers comprising a link, 
with a maximum distance between any two corresponding transceivers of up to 
five miles (or shorter distances in certain areas; weather conditions may 
necessitate distances as short as 1.1 miles between transceivers to maintain 
desired transmission quality). The areas in which such shorter distances are 
required are those where rainfall intensity and the size of the raindrops 
adversely impact transmission quality at longer distances. Other weather 
conditions, such as snow, electrical storms and high winds, have not, in the 
Company's experience, affected the quality or reliability of Wireless Fiber 
services. The establishment of Wireless Fiber services may require additional 
transceivers to triangulate around obstacles (such as buildings). Similarly, 
to establish Wireless Fiber services covering a distance in excess of five 
miles, additional transceivers are required to establish a chain with links 
no more than five miles apart or to establish a system of interconnected hub 
sites. The cost of additional transceivers where required by weather, 
physical obstacles or distance may render Wireless Fiber uneconomical in 
certain instances. The Company must obtain Roof Rights (or rights to access 
other locations where lines of sight are available) in each building where a 
transceiver will be placed. The Company seeks to prequalify and obtain Roof 
Rights at buildings targeted by potential customers in its licensed areas in 
advance of anticipated orders. There can be no assurance, however, that the 
Company will be successful in obtaining Roof Rights necessary to establish 
its Wireless Fiber services in its potential markets. The Company's 
prequalification activities often require the payment of option fees to the 
owners of buildings that are being prequalified. There can be no assurance 
that the Company will receive orders for Wireless Fiber services which allow 
the Company to utilize Roof Rights it obtains.

UNCERTAINTY OF MARKET ACCEPTANCE OF WIRELESS FIBER SERVICES

    The Company has been marketing its Wireless Fiber services since December 
1994.  The Company has not obtained a significant market share in any of the 
licensed areas where it offers Wireless Fiber services. The provision of 
wireless local telecommunications services over 38 GHz represents an emerging 
sector of the telecommunications industry and the demand for and acceptance 
of Wireless Fiber services are subject to a high level of uncertainty. 
Despite the Company's initial success in attracting customers, there can be 
no assurance that substantial markets will develop for wireless local 
telecommunications services delivered over 38 GHz or that, even if such 
markets develop, the Company will be able to succeed in positioning itself as 
a provider of such services or provide such services profitably. The 
Company's success in providing wireless broadband services is subject to a 
number of factors beyond the Company's control. These factors include, 
without limitation, historical perceptions of the unreliability and lack of 
security of previous microwave radio technologies, changes in general and 
local economic conditions, availability of equipment, changes in 
telecommunications service rates charged by other service providers, changes 
in the supply and demand for wireless broadband services, competition from 
wireline and wireless operators in the same market area and changes in the 
federal and state regulatory schemes affecting the operations of 
telecommunications service providers in general and wireless broadband 
systems in particular (including the enactment of new statutes and the 
promulgation of changes in the interpretation or enforcement of existing or 
new rules and regulations). In addition, the extent of the potential demand 
for wireless broadband services in the Company's target markets cannot be 
estimated with certainty. There can be no assurance that one or more of these 
factors will not have an adverse effect on the Company's financial condition 
and results of operations and the ability of the Company and its subsidiaries 
to make principal and interest payments on their outstanding debt, including 
the Notes.

ABSENCE OF PUBLIC MARKET FOR THE NEW NOTES

    There is no public market and only a limited secondary market for the New 
Notes.  The Old Notes are and the New Notes will be designated eligible for 
trading in The Private Offerings, Resales and Trading through Automated 
Linkages (PORTAL) Market of The Nasdaq Stock Market, Inc.  New Notes traded 
after their initial issuance may trade at a discount from their initial 
offering price, depending upon prevailing interest rates, the market for 
similar securities and other factors, including general economic conditions 
and the financial condition of, performance of, and prospects for the Company.

INVESTMENT COMPANY ACT CONSIDERATIONS

    After giving effect to the October 1997 Debt Placement, the Company had 
substantial cash, cash equivalents and short-term investments. See 
"Capitalization." Such amount may be invested from time to time in investment 
securities, which may result in the Company being treated as an "investment 
company" under the Investment Company Act of 1940 (the "1940 Act"). The 1940 
Act requires the registration of, and imposes various substantive 
restrictions on, certain companies ("investment companies") that are, or hold 
themselves out as being, engaged primarily, or propose to engage primarily 
in, the business of investing, reinvesting or trading in securities, or that 
fail certain statistical tests regarding composition of assets and sources of 
income and are not primarily engaged in businesses other than investing, 
reinvesting, owning, holding or trading securities. 

    The Company believes that it is primarily engaged in a business other 
than investing, reinvesting, owning, holding or trading securities and, 
therefore, is not an investment company within the meaning of the 1940 Act. 
If the Company is found to be an investment company, it intends to rely upon 
an exemption from the 1940 Act for certain "transient" or temporary 
investment companies. However, such exemption is only available for one year. 

    If the Company was required to register as an investment company under 
the 1940 Act, it would become subject to substantial regulation with respect 
to its capital structure, management, operations, transactions with 
affiliated persons (as defined in the 1940 Act) and other matters. 
Application of the provisions of the 1940 Act to the Company would have a 
material adverse effect on the Company. In addition, if the Company is an 
investment company under the 1940 Act, the Notes will not be eligible to be 
resold in reliance on Rule 144A under the Securities Act and certain holders 
of the Notes may not be able to own the Notes. In such event, the market 
price of the Notes may be adversely affected.

CONSEQUENCES OF THE EXCHANGE OFFER ON NON-TENDERING HOLDERS OF THE OLD NOTES

    After Exchange Offer is consummated, the Company may not be required to 
register certain of the Old Notes not tendered and accepted in the Exchange 
Offer.  In such event, holders of certain of the Old Notes seeking liquidity 
in their investment would have to rely on exemptions to the registration 
requirements under the securities laws, including the Securities Act.  
Following the consummation of the Exchange Offer, certain of the Old Notes 
may not be entitled to the contingent increase in interest rate provided for 
in the event of a failure to consummate the Exchange Offer in accordance with 
the terms of the Registration Agreement.

                                       30


<PAGE>


                                THE EXCHANGE OFFER

PURPOSE AND EFFECT OF THE EXCHANGE OFFER

    The Old Notes were sold by the Company in the October 1997 Debt Placement 
to the Initial Purchasers who, in turn, sold such Old Notes to certain 
qualified institutional buyers in reliance on Rule 144A under the Securities 
Act.  In connection with the October 1997 Debt Placement, the Company entered 
into the Registration Agreement, pursuant to which the Company is obligated 
to use its best efforts to consummate this Exchange Offer of the Old Notes 
for the New Notes pursuant to an effective registration statement by April 6, 
1998.  Unless the context requires otherwise, the term "holder" with respect 
to the Exchange Offer means any person in whose name Old 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 
Notes are held of record by DTC (who may deliver such Old Notes by book-entry 
transfer at DTC).

    The Company has not requested, and does not intend to request, an 
interpretation by the staff of the Commission with respect to whether the New 
Notes issued pursuant to the Exchange Offer in exchange for the Old Notes may 
be offered for sale, resold or otherwise transferred by any holder without 
compliance with the registration and prospectus delivery provisions of the 
Securities Act. Based on interpretations by the staff of the Commission set 
forth in no-action letters issued to third parties, the Company believes that 
New Notes issued pursuant to the Exchange Offer in exchange for Old Notes may 
be offered for resale, resold and otherwise transferred by any holder of such 
New Notes (except in the case of broker-dealers, as set forth below) 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. Any holder who tenders in the Exchange Offer for the purpose of 
participating in a distribution of the New Notes may not rely on such 
interpretation by the staff of the Commission and must comply with the 
registration and prospectus delivery requirements of the Securities Act in 
connection with any secondary resale transaction.  Each broker-dealer that 
receives New Notes for its own account in exchange for Old Notes, where such 
Old Notes were acquired by such broker-dealer as a result of market-making 
activities or other trading activities, must acknowledge that it will deliver 
a prospectus in connection with any resale of such New Notes.  See "Plan of 
Distribution."

    By tendering in the Exchange Offer, each holder of Old Notes will 
represent to the Company that, among other things, (i) the New Notes acquired 
pursuant to the Exchange Offer are being obtained in the ordinary course of 
business of the person receiving such New Notes, whether or not such person 
is such holder, (ii) neither the holder of Old Notes nor any such other 
person has an arrangement or understanding with any person to participate in 
the distribution of New Notes, and (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.

    Following the consummation of the Exchange Offer, holders of Old Notes 
not tendered will no longer have certain registration rights and the Old 
Notes will continue to be subject to certain restrictions on transfer. 
Accordingly, the liquidity of the market for the Old Notes could be adversely 
affected.

TERMS OF THE EXCHANGE OFFER

    Upon the terms and subject to the conditions set forth in this Prospectus 
and in the Letter of Transmittal, the Company will accept any and all Old 
Notes validly tendered and not withdrawn prior to 5:00 p.m., New York City 
time, on the Expiration Date.  Subject to the minimum denomination 
requirements of the New Notes, The Company will issue $1,000 principal amount 
of New Notes in exchange for each $1,000 principal amount of outstanding Old 
Notes accepted in the Exchange Offer.  Holders may tender some or all of 
their Old Notes pursuant to the Exchange Offer.  However, Old Notes may be 
tendered only in integral multiples of $1,000 principal amount.

    The forms and terms of the New Notes will be identical in all material 
respects to the forms and terms of the corresponding Old Notes, except that 
the New Notes will have been registered under the Securities Act and, 
therefore, will not bear legends restricting the transfer thereof.  The 
Exchange Offer is not conditioned upon any minimum aggregate principal amount 
at maturity of Old Notes being tendered for exchange.  DTC is the sole 
registered holder 

                                       31


<PAGE>


of the Old Notes, and holds such notes on behalf of numerous participants.  
This Prospectus, together with the Letter of Transmittal, is being sent to 
all such registered holders as of December ___, 1997.

    Under the Indenture, holders of Old Notes do not have any appraisal or 
dissenters rights in connection with the Exchange Offer.  The Company intends 
to conduct the Exchange Offer in accordance with the applicable requirements 
of the Exchange Act and the applicable rules and regulations of the 
Commission thereunder.

    The Company shall be deemed to have accepted validly tendered Old Notes 
when, as and if it has given oral or written notice thereof to the Exchange 
Agent.  The Exchange Agent will act as agent for the tendering holders for 
the purpose of receiving the New Notes from The Company.  If any tendered Old 
Notes are not accepted for exchange, such unaccepted Old Notes will be 
returned, without expense, to the tendering holder thereof as promptly as 
practicable after the Expiration Date.

    Holders who tender Old Notes in the Exchange Offer will not be required 
to pay brokerage commissions or fees or, subject to the instructions in the 
Letter of Transmittal, transfer taxes with respect to the exchange of Old 
Notes pursuant to the Exchange Offer.  The Company will pay all charges and 
expenses, other than certain applicable taxes, in connection with the 
Exchange Offer.  See " -- Fees and Expenses."

EXPIRATION DATE; EXTENSIONS; AMENDMENTS

    The term "Expiration Date" shall mean 5:00 p.m., New York City time, on 
January __, 1998 unless the Company in its sole discretion extends the 
Exchange Offer, in which case the term "Expiration Date" shall mean the 
latest date and time to which the Exchange Offer is extended.  Although the 
Company has no current intention to extend the Exchange Offer, the Company 
reserves the right to extend the Exchange Offer at any time and from time to 
time by giving oral or written notice to the Exchange Agent and by timely 
public announcement communicated, unless otherwise required by applicable law 
or regulation, by making a release to the Dow Jones News Service.  During any 
extension of the Exchange Offer, all Old Notes previously tendered pursuant 
to the Exchange Offer and not withdrawn will remain subject to the Exchange 
Offer.  The date of the exchange of the New Notes for Old Notes will be the 
first New York Stock Exchange trading day following the Expiration Date.

    The Company expressly reserves the right to (i) terminate the Exchange 
Offer and not accept for exchange any  Old Notes if any of the events set 
forth below under " -- Conditions to the Exchange Offer" shall have occurred 
and shall not have been waived by the Company and (ii) amend the terms of the 
Exchange Offer in any manner which, in its good faith judgment, is 
advantageous to the holders of the Old Notes, whether before or after any 
tender of the Old Notes.

PROCEDURES FOR TENDERING

    The tender to the Company of Old Notes by a holder thereof pursuant to 
one of the procedures set forth below will constitute an agreement between 
such holder and The Company in accordance with the terms and subject to the 
conditions set forth herein and in the Letter of Transmittal signed by such 
holder.  A holder of the Old Notes may tender such Old Notes by (i) properly 
completing and signing a Letter of Transmittal or a facsimile thereof (all 
references in this Prospectus to a Letter of Transmittal shall be deemed to 
include a facsimile thereof) and delivering the same, together with any 
corresponding certificate or certificates representing the Old Notes being 
tendered (if in certificated form) and any required signature guarantees, to 
the Exchange Agent at its address set forth in the Letter of Transmittal on 
or prior to the Expiration Date (or complying with the procedure for 
book-entry transfer described below) or (ii) complying with the guaranteed 
delivery procedures described below.

    If tendered Old Notes are registered in the name of the signer of the 
Letter of Transmittal and the New Notes to be issued in exchange therefor are 
to be issued (and any untendered Old Notes are to be reissued) in the name of 
the registered holder (which term, for the purposes described herein, shall 
include any participant in DTC whose name appears on a security listing as 
the owner of Old Notes), the signature of such signer need not be guaranteed. 
 In any other case, the tendered Old Notes must be endorsed or accompanied by 
written instruments of transfer in form satisfactory to the Company and duly 
executed by the registered holder and the signature on the endorsement or 
instrument of transfer must be guaranteed by a member firm of a registered 
national securities exchange or of the 

                                       32


<PAGE>


National Association of Securities Dealers, Inc., a commercial bank or trust 
company having an office or correspondent in the United States or an 
"eligible guarantor institution" as defined by Rule 17Ad-15 under the 
Exchange Act (any of the foregoing hereinafter referred to as an "Eligible 
Institution").  If the New Notes and/or Old Notes not exchanged are to be 
delivered to an address other than that of the registered holder appearing on 
the register for the Old Notes, the signature in the Letter of Transmittal 
must be guaranteed by an Eligible Institution.

    THE METHOD OF DELIVERY OF OLD NOTES, LETTER OF TRANSMITTAL AND ALL OTHER 
DOCUMENTS IS AT THE ELECTION AND RISK OF THE HOLDER.  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 LETTER OF TRANSMITTAL OR OLD NOTES SHOULD BE 
SENT TO THE COMPANY.

    The Company understands that the Exchange Agent will make a request 
promptly after the date of this Prospectus to establish accounts with respect 
to the Old Notes at DTC for the purpose of facilitating the Exchange Offer, 
and subject to the establishment thereof, any financial institution that is a 
participant in DTC's system may make book-entry delivery of Old Notes by 
causing DTC to transfer such Old Notes into the Exchange Agent's account with 
respect to the Old Notes in accordance with DTC's procedure for such 
transfer. Although delivery of the Old Notes may be effected through 
book-entry transfer into the Exchange Agent's account at DTC, an appropriate 
Letter of Transmittal with any required signature guarantee and all other 
required documents must in each case be transmitted to and received or 
confirmed by the Exchange Agent at the address set forth in the Letter of 
Transmittal on or prior to the Expiration Date, or, if the guaranteed 
delivery procedures described below are complied with, within the time period 
provided under such procedures.

    If the holder desires to accept the Exchange Offer and time will not 
permit a Letter of Transmittal or Old Notes 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 the Exchange Agent 
has received at its office, on or prior to the Expiration Date, a letter, 
telegram or facsimile transmission from an Eligible Institution setting forth 
the name and address of the tendering holder, the name(s) in which the Old 
Notes are registered and the certificate number(s) of the Old Notes to be 
tendered, and stating that the tender is being made thereby and guaranteeing 
that, within three New York Stock Exchange trading days after the date of 
execution of such letter, telegram or facsimile transmission by the Eligible 
Institution, such Old Notes, in proper form for transfer (or a confirmation 
of book-entry transfer of such Old Notes into the Exchange Agent's account at 
DTC), will be delivered by such Eligible Institution together with a properly 
completed and duly executed Letter of Transmittal (and any other required 
documents).  Unless Old Notes being tendered by the above-described method 
are deposited with the Exchange Agent within the time period set forth above 
(accompanied or preceded by a properly completed Letter of Transmittal and 
any other required documents), the Company may, at its option, reject the 
tender. Copies of a Notice of Guaranteed Delivery which may be used by 
Eligible Institutions for the purposes described in this paragraph are 
available from the Exchange Agent.

    A tender will be deemed to have been received as of the date when (i) the 
tendering holder's properly completed and duly signed Letter of Transmittal 
accompanied by the Old Notes (or a confirmation of book-entry transfer of 
such Old Notes into the Exchange Agent's account at DTC) is received by the 
Exchange Agent or (ii) a Notice of Guaranteed Delivery or letter, telegram or 
facsimile transmission to similar effect (as provided above) from an Eligible 
Institution is received by the Exchange Agent.  Issuances of New Notes in 
exchange for Old Notes tendered pursuant to a Notice of Guaranteed Delivery 
or letter, telegram or facsimile transmission to similar effect (as provided 
above) by an Eligible Institution will be made only against submission of a 
duly signed Letter of Transmittal (and any other required documents) and 
deposit of the tendered Old Notes.

    All questions as to the validity, form, eligibility (including time of 
receipt) and acceptance for exchange of any tender of Old Notes will be 
determined by the Company, whose determination will be final and binding.  
The Company reserves the absolute right to reject any or all tenders not in 
proper form or the acceptance for exchange of which may, in the opinion of 
the Company's counsel, be unlawful.  The Company also reserve the absolute 
right to waive any of the conditions of the Exchange Offer or any defect or 
irregularity in the tender of any Old Notes.  None of The Company, the 
Exchange Agent or any other person will be under any duty to give 
notification of any defects or irregularities in tenders or incur any 
liability for failure to give any such notification.  If any Old Notes 
received by the 

                                       33


<PAGE>


Exchange Agent are not validly tendered and as to which the defects or 
irregularities have not been cured or waived, or if Old Notes are submitted 
in a principal amount greater than the principal amount of Old Notes being 
tendered by such tendering holder, such unaccepted or non-exchanged Old Notes 
will be returned by the Exchange Agent to the tendering holders, unless 
otherwise provided in the Letter of Transmittal, as soon as practicable 
following the Expiration Date.

    In addition, the Company reserves the right in its sole discretion, to 
the extent permitted by the Indenture to (a) purchase or make offers for any 
Old Notes that remain outstanding subsequent to the Expiration Date and (b) 
to the extent pertained by applicable law, purchase Old Notes in the open 
market, in privately negotiated transactions or otherwise.  The terms of any 
such purchases or offers will differ from the terms of the Exchange Offer.

TERMS AND CONDITIONS OF THE LETTER OF TRANSMITTAL

    The Letter of Transmittal contains, among other things, the following 
terms and conditions, which are part of the Exchange Offer.

    The party tendering Old Notes for exchange ("Transferor") exchanges, 
assigns and transfers the Old Notes to the Company and irrevocably 
constitutes and appoints the Exchange Agent as the Transferor's agent and 
attorney-in-fact to cause the Old Notes to be assigned, transferred and 
exchanged.  The Transferor represents and warrants that it has full power and 
authority to tender, exchange, assign and transfer the Old Notes and to 
acquire New Notes issuable upon the exchange of such tendered Old Notes, and 
that, when the same are accepted for exchange, the Company will acquire good 
and unencumbered title to the tendered Old Notes, free and clear of all 
liens, restrictions, charges and encumbrances and not subject to any adverse 
claim.  The Transferor also warrants that it will, upon request, execute and 
deliver any additional documents deemed by the Company to be necessary or 
desirable to complete the exchange, assignment and transfer of tendered Old 
Notes or transfer ownership of such Old Notes on the account books maintained 
by DTC.  All authority conferred by the Transferor will survive the death, 
bankruptcy or incapacity of the Transferor and every obligation of the 
Transferor shall be binding upon the heirs, legal representatives, 
successors, assigns, executors and administrators of such Transferor.

    By executing a Letter of Transmittal, each holder will make to the 
Company the representations set forth above in the third paragraph under the 
heading " -- Purpose and Effect of the Exchange Offer."

WITHDRAWAL OF TENDERS

    Tenders of Old Notes pursuant to the Exchange Offer are irrevocable, 
except that Old Notes tendered pursuant to the Exchange Offer may be 
withdrawn at any time prior to 5:00 p.m., New York City time, on the 
Expiration Date.

    To be effective, a written, telegraphic, or facsimile transmission notice 
of withdrawal must be timely received by the Exchange Agent at the address 
set forth in the Letter of Transmittal prior to 5:00 p.m., New York City time 
on the Expiration Date.  Any such notice of withdrawal must specify the 
holder named in the Letter of Transmittal as having tendered Old Notes to be 
withdrawn, the certificate numbers and designation of Old Notes to be 
withdrawn, the principal amount of Old Notes delivered for exchange, a 
statement that such holder is withdrawing his election to have such Old Notes 
exchanged, and the name of the registered holder of such Old 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 
Notes being withdrawn.  The Exchange Agent will return the properly withdrawn 
Old Notes promptly following receipt of notice of withdrawal.  If  Old  Notes 
have been tendered pursuant to the procedure for book-entry transfer, any 
notice of withdrawal must specify the name and number of the account at DTC 
to be credited with the withdrawn Old Notes or otherwise comply with DTC 
procedure.  All questions as to the validity of notices of withdrawal, 
including time of receipt, will be determined by the Company and such 
determination will be final and binding on all parties.

CONDITIONS TO THE EXCHANGE OFFER

    Notwithstanding any other provision of the Exchange Offer, or any 
extension of the Exchange Offer,  the Company will not be required to issue 
New Notes in exchange for any properly tendered Old Notes not theretofore 
accepted and may terminate the Exchange Offer, or, at their  option, modify 
or otherwise amend the Exchange Offer, if either of the following events 
occur:

         (a)  any statute, rule or regulation shall have been enacted, or any 
    action shall have been taken by any court or governmental authority 
    which, in the sole judgment of the Company, would prohibit, restrict or 
    otherwise render illegal the consummation of the Exchange Offer, or 

         (b)  there shall occur a change in the current interpretation by the 
    staff of the Commission which, in the Company's sole judgment, might 
    materially impair The Company's ability to proceed with the Exchange 
    Offer. 

    The Company expressly reserves the right to terminate the Exchange Offer 
and not accept for exchange any Old Notes upon the occurrence of either of 
the foregoing conditions (which represent all of the material conditions to 
the acceptance by The Company of properly tendered Old Notes).

    The foregoing conditions are for the sole benefit of the Company and may 
be waived by the Company if it is legally permitted to do so, in whole or in 
part, in its sole discretion.  The foregoing conditions must be either 
satisfied or waived prior to termination of the Exchange Offer.  Any 
determination made by the Company concerning an event, development or 
circumstance described or referred to above will be final and binding on all 
parties.

FEES AND EXPENSES

    The expense of soliciting tenders will be borne by the Company.  The 
principal solicitation is being made by mail; however, additional 
solicitations may be made by telegraph, telephone or in person by officers 
and regular employees of the Company and its affiliates.  No additional 
compensation will be paid to any such officers and employees who engage in 
soliciting tenders.

    The Company has not retained any dealer-manager or other soliciting agent 
in connection with the Exchange Offer and will not make any payments 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 Company may also pay brokerage houses 
and other custodians, nominees and fiduciaries the reasonable out-of-pocket 
expenses incurred by them in forwarding copies of this Prospectus, the Letter 
of Transmittal and related documents to the beneficial owners of the Old 
Notes and in handling or forwarding tenders for exchange.

    The expenses to be incurred by the Company in connection with the 
Exchange Offer, including fees and expenses of the Exchange Agent and Trustee 
and accounting and legal fees, will be paid by the Company.  The Company will 
not, however, pay the costs incurred by a holder in delivering its Old Notes 
to the Exchange Agent, underwriting fees, or Commissions or transfer taxes.

ACCOUNTING TREATMENT

    The New Notes will be recorded at the same carrying value as the Old 
Notes as reflected in the Company's accounting records on the date of the 
exchange because the exchange of the Old Notes for the New Notes is the 
completion of the selling process contemplated in the issuance of the Old 
Notes. Accordingly, no gain or loss for accounting purposes will be 
recognized.  The expenses of the Exchange Offer and the unamortized expenses 
related to the issuance of the Old Notes will be amortized over the term of 
the New Notes.

OTHER MATTERS

    Participation in the Exchange Offer is voluntary and holders should 
carefully consider whether to accept. Holders of the Old Notes are urged to 
consult their financial and tax advisors in making their own decisions on 
what action to take.

    No person has been authorized to give any information or to make any 
representations in connection with the Exchange Offer other than those 
contained in this Prospectus.  If given or made, such information or 
representations should not be relied upon as having been authorized by the 
Company.  Neither the delivery of this Prospectus nor any exchange made 
hereunder shall, under any circumstances, create any implication that there 
has been no change in the affairs of the Company since the dates as of which 
information is given herein. The Exchange Offer is not being made to (nor 
will tenders be accepted from or on behalf of) holders of Old Notes in any 
jurisdiction in which the making of the Exchange Offer or the acceptance 
thereof would not be in compliance with the laws of such jurisdiction. 
However, the Company may, at its discretion, take such action as it may deem 
necessary to make the Exchange Offer in any such jurisdiction and extend the 
Exchange Offer to holders of Old Notes in such jurisdiction. 

                                       36


<PAGE>


    As a result of the making of the Exchange Offer, the Company will have 
fulfilled a covenant contained in the Registration Agreement.  Holders of the 
Old Notes who do not tender their Old Notes in the Exchange Offer will 
continue to hold such Old Notes and will be entitled to all the rights and 
limitations applicable thereto under the Indenture except for certain rights 
under the Registration Agreement and except that certain of the Old Notes may 
not be entitled to the contingent increase in interest rate provided for in 
the Old Notes.  All untendered Old Notes will continue to be subject to the 
restrictions on transfer set forth in the Indenture and the Old Notes.  To 
the extent that Old Notes are tendered and accepted in the Exchange Offer, 
the trading market, if any, for untendered Old Notes could be adversely 
affected.

    The Company will not receive any cash proceeds from the issuance of the 
New Notes offered hereby.  In consideration for issuing the New Notes as 
contemplated in this Prospectus, the Company will receive in exchange Old 
Notes, in like principal amount, the terms of which are identical to the New 
Notes except that such New Notes will be registered under the Securities Act 
and, therefore, will not bear legends restricting the transfer thereof.  Old 
Notes surrendered in exchange for New Notes will be retired and canceled and 
cannot be reissued. Accordingly, issuance of the New Notes will not result in 
a change in the indebtedness of the Company.

                            DESCRIPTION OF THE NOTES

    The Old Notes were issued in the October 1997 Debt Placement under the 
Indenture, dated as of October 1, 1997, between WinStar (for the purposed of 
this Description of Notes, "WCI"), and United States Trust Company of New 
York, as trustee (in such capacity, the "Trustee").  Copies of the form of 
Indenture are available on request from WCI.

    The New Notes will be issued under the Indenture.  The form and terms of 
the New Notes are the same as the form and terms of the Old Notes, except 
that the New Notes will have been registered under the Securities Act, and 
therefore, will not bear legends restricting transfer thereof.  The New Notes 
will  evidence the same debt as the Old Notes.  Upon consummation of this 
Exchange Offering, the New Notes will be treated as a single class under the 
Indenture with any Old Notes remaining outstanding.    Upon the consummation 
of this Exchange Offer, holders of Old Notes may not be entitled to certain 
registration rights under, or the contingent increase in interest rate 
provided by, the Registration Agreement. 

GENERAL

    The Notes will be issued only in fully registered form, without coupons, 
in denominations of $1,000 of principal amount and any integral multiple of 
$1,000. See "--Book-Entry, Delivery and Form." No service charge will be made 
for any registration of transfer or exchange of Notes, but WCI may require 
payment of a sum sufficient to cover any transfer tax or other similar 
governmental charge payable in connection therewith. The Notes may be 
exchanged or transferred at the office or agency of WCI in the Borough of 
Manhattan, The City of New York (which initially will be the corporate trust 
office of the Trustee at 114 West 47th Street, New York, New York 
10036-1532). 

    Although for United States federal income tax purposes a significant 
amount of original issue discount, taxable as ordinary income, will be 
recognized by a Holder of Notes as such discount is amortized from the date 
of issuance of the Notes, Holders of Notes will not receive any payments on 
the Notes until September 1, 2002. For a description of certain tax matters 
related to an investment in the Notes, see "Certain United States Federal 
Income Tax Considerations." 

TERMS OF THE NOTES

    The Notes are unsecured, senior subordinated obligations of WCI, limited 
to $100.0 million aggregate principal amount, and will mature on March 1, 
2007. Until March 1, 2002, interest on the Notes will accrue at a rate of 15% 
per annum and be compounded semiannually on each SemiAnnual Interest Accrual 
Date with respect to the Notes, but, except as described herein, will not be 
payable in cash. Interest on the Accumulated Amount of each Note as of March 
1, 2002 will be paid semiannually, commencing September 1, 2002, to Holders 
of record at the close of business on the February 15 or August 15 
immediately preceding the interest payment date of March 1 and September 1 of 
each year. Interest on the Notes will be paid on a 360-day year, twelve 
30-day month basis. 

OPTIONAL REDEMPTION

    The Notes are not redeemable prior to March 1, 2002. Thereafter, the 
Notes will be redeemable, at WCI's option, in whole at any time, or in part 
from time to time, upon not less than 30 nor more than 60 days' prior notice 
mailed by first-class mail to each Holder's registered address, at the 
following redemption prices (expressed as a percentage of the Accumulated 
Amount of the Notes), plus accrued and unpaid interest, if any, on such 
Accumulated Amount to the redemption date (subject to the right of Holders of 
record on the relevant regular record date that is on or prior to the 
redemption date to receive interest due on the relevant interest payment 
date), if redeemed during the 12-month period commencing March 1 of the years 
set forth below: 

                                                                  Note

<PAGE>

    Selection of Notes for Optional Redemption

    In the case of any partial optional redemption, selection of the Notes 
for redemption will be made by the Trustee in compliance with the 
requirements of the principal national securities exchange, if any, on which 
the Notes are listed or, if the Notes are not listed on a national securities 
exchange, on a pro rata basis, by lot or such other method as the Trustee, in 
its sole discretion, shall deem fair and appropriate; provided, however, that 
no Note of $1,000 in principal amount or less shall be redeemed in part. If 
any Note is to be redeemed in part only, the notice of redemption relating to 
such Note shall state the portion of the principal amount thereof to be 
redeemed. A new Note in principal amount equal to the unredeemed portion 
thereof will be issued in the name of the Holder thereof upon cancellation of 
the original Note. 

    WCI's ability to redeem the Notes at its option is severely limited under 
the terms of WCI's outstanding indebtedness. WCI may not be able to redeem 
the Notes at its option unless it simultaneously redeems or repays such other 
indebtedness. 

Ranking

    The indebtedness evidenced by the Notes represents unsecured senior 
subordinated obligations of WCI. The payment of the Senior Subordinated 
Obligations will, to the extent set forth in the Indenture, be subordinated 
in right of payment to the prior payment in full, in cash or cash 
equivalents, of all Senior Indebtedness of WCI, including, without 
limitation, WCI's obligations under the 1995 Senior Notes, the 1997 Senior 
Notes and the Equipment Note Guarantees, as well as WCI's guarantees under 
the Equipment Lease Financing, the CIT Credit Facility, the Revolving Credit 
Facility and the Finova Lease Financing. As of the Issue Date, there was no 
indebtedness of WCI outstanding pari passu with or junior to the Notes, 
except for the Convertible Notes, which rank pari passu with the Notes. See 
"Risk Factors--Substantial Indebtedness; Ability to Service Indebtedness" and 
"--Holding Company Structure; Ranking of the Notes; Unsecured Indebtedness" 
and "Capitalization." 

    "Senior Subordinated Obligations" is defined in the Indenture to mean any 
principal of, premium, if any, or interest on the Notes payable pursuant to 
the terms of the Notes or upon acceleration, to the extent relating to the 
purchase of Notes or amounts corresponding to such principal, premium, if 
any, or interest on the Notes. 

    At September 30, 1997, after giving effect to the October 1997 Debt 
Placement and the US ONE Asset Acquisition and Financing, WCI had (on an 
unconsolidated basis) approximately $820.9 million of indebtedness (including 
the Equipment Note and US ONE Financing Guarantees), $561.1 million of which 
would have been senior indebtedness and $197.5 million of which would have 
been senior subordinated indebtedness. 

    WCI is a holding company. Substantially all the operations of WCI are 
conducted through its subsidiaries. Claims of creditors of such subsidiaries, 
including trade creditors, secured creditors and creditors holding 
indebtedness and guarantees issued by such subsidiaries, and claims of 
preferred stockholders (if any) of such subsidiaries, generally will have 
priority with respect to the assets and earnings of such subsidiaries over 
the claims of creditors of WCI, including holders of the Notes. The Notes, 
therefore, are effectively subordinated to creditors (including trade 
creditors) and preferred stockholders (if any) of subsidiaries of WCI. At 
September 30, 1997, the total liabilities of WCI's subsidiaries was 
approximately $395.6 million, including trade payables. Although the 
Indentures limit the incurrence of Indebtedness and the issuance of preferred 
stock of certain of WCI's subsidiaries, such limitations are subject to a 
number of significant qualifications. Moreover, the Indentures do not impose 
any limitation on the incurrence by such subsidiaries of liabilities that are 
not considered Indebtedness under the Indentures. 

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

                                     40
<PAGE>

obligation so declared fraudulent, invalid or otherwise set aside (and all 
other amounts that would come due with respect thereto had such obligation 
not been so affected) shall be deemed to be reinstated and outstanding as 
Senior Indebtedness of WCI for all purposes of the Indenture as if such 
declaration, invalidity or setting aside had not occurred. Upon any payment 
or distribution of assets or securities of WCI of any kind or character, 
whether in cash, property or securities, upon any dissolution or winding up 
or total or partial liquidation or reorganization of WCI, whether voluntary 
or involuntary or in bankruptcy, insolvency, receivership or other 
proceedings, all amounts due or to become due upon all Senior Indebtedness of 
WCI (including any interest accruing subsequent to an event of bankruptcy, 
whether or not such interest is an allowed claim enforceable against the 
debtor under the Bankruptcy Code) shall first be paid in full, in cash or 
cash equivalents, before the Holders of the Notes or the Trustee, on behalf 
of the Holders of the Notes, shall be entitled to receive any payment by WCI 
on account of Senior Subordinated Obligations, or any payment to acquire any 
of the Notes for cash, property or securities, or any distribution with 
respect to the Notes of any cash, property or securities. Before any payment 
may be made by, or on behalf of, WCI of any Notes upon any such dissolution, 
winding up, liquidation or reorganization, any payment or distribution of 
assets or securities of WCI of any kind or character, whether in cash, 
property or securities, to which the Holders of the Notes or the Trustee, on 
behalf of the Holders of the Notes, would be entitled, but for the 
subordination provisions of the Indenture, shall be made by WCI or by any 
receiver, trustee in bankruptcy, liquidating trustee, agent or other similar 
Person making such payment or distribution or by the Holders of the Notes or 
the Trustee if received by them or it, directly to the holders of the Senior 
Indebtedness of WCI (pro rata to such holders on the basis of the respective 
amounts of Senior Indebtedness of WCI held by such holders) or their 
representatives as their respective interests appear, to the extent necessary 
to pay all such Senior Indebtedness in full, in cash or cash equivalents, 
after giving effect to any concurrent payment, distribution or provision 
therefor to or for the holders of such Senior Indebtedness. 

    No direct or indirect payment by or on behalf of WCI of Senior 
Subordinated Obligations, whether pursuant to the terms of the Notes or upon 
acceleration or otherwise, shall be made if, at the time of such payment, 
there exists a default in the payment of all or any portion of the 
obligations on any Senior Indebtedness of WCI, and such default shall not 
have been cured or waived or the benefits of this sentence waived by or on 
behalf of the holders of such Senior Indebtedness. In addition, during the 
continuance of any other event of default with respect to any Designated 
Senior Indebtedness of WCI pursuant to which the maturity thereof may be 
accelerated, upon receipt by the Trustee of written notice from the trustee 
or other representative for the holders of such Designated Senior 
Indebtedness (or the holders of at least a majority in principal amount of 
such Designated Senior Indebtedness then outstanding), no payment of Senior 
Subordinated Obligations may be made by or on behalf of WCI upon or in 
respect of the Notes for a period (a "Payment Blockage Period") commencing on 
the date of receipt of such notice and ending 159 days thereafter (unless, in 
each case, such Payment Blockage Period shall be terminated by written notice 
to the Senior Subordinated Notes Trustee for such trustee of, or other 
representatives for, such holders). Not more than one Payment Blockage Period 
may be commenced with respect to the Notes during any period of 360 
consecutive days. Notwithstanding anything in the Indenture to the contrary, 
there must be 180 consecutive days in any 360-day period in which no Payment 
Blockage Period is in effect. No event of default that existed or was 
continuing (it being acknowledged that any subsequent action that would give 
rise to an event of default pursuant to any provision under which an event of 
default previously existed or was continuing shall constitute a new event of 
default for this purpose) on the date of the commencement of any Payment 
Blockage Period with respect to the Designated Senior Indebtedness of WCI 
initiating such Payment Blockage Period shall be, or shall be made, the basis 
for the commencement of a second Payment Blockage Period by the 
representative for, or the holders of, such Designated Senior Indebtedness, 
whether or not within a period of 360 consecutive days, unless such event of 
default shall have been cured or waived for a period of not less than 90 
consecutive days. 

    By reason of the subordination provisions described above, in the event 
of liquidation or insolvency, creditors of WCI who are not holders of Senior 
Indebtedness of WCI may recover less, ratably, than holders of Senior 
Indebtedness of WCI and may recover more, ratably, than Holders of the Notes. 

    "Senior Indebtedness" as defined under the Indenture means the following 
obligations of WCI, whether outstanding on the Issue Date or thereafter 
Incurred: (i) all Indebtedness and all other monetary obligations of WCI 
under the 1995 Senior Notes, the 1997 Senior Notes and the Equipment Note 
Guarantees, (ii) all other Indebtedness of WCI (other than the Notes and the 
Convertible Notes), including principal and interest on such Indebtedness, 
unless such Indebtedness, by its terms or by the terms of any agreement or 
instrument pursuant to which such Indebtedness is issued, is pari passu with, 
or subordinated in right of payment to, the Notes and (iii) all fees, 
expenses and indemnities payable in connection with the 1995 Senior Notes, 
the 1997 Senior Notes and the Equipment Note Guarantees (including any 

                                     41
<PAGE>

agreements pursuant to which the 1995 Senior Notes, the 1997 Senior Notes or 
the Equipment Note Guarantees were issued); provided, however, that the term 
"Senior Indebtedness" as defined in the Indenture shall not include (a) any 
Indebtedness of WCI that, when Incurred and without respect to any election 
under Section 1111(b) of the Bankruptcy Code, was without recourse to WCI, 
(b) any Indebtedness of WCI to a Subsidiary of WCI or to a joint venture in 
which WCI has an interest, (c) any Indebtedness of WCI, to the extent not 
permitted pursuant to the covenants described under "--Covenants--Limitation 
on Indebtedness" or "--Covenants--Limitation on Senior Subordinated 
Indebtedness", (d) any repurchase, redemption or other obligation in respect 
of Redeemable Stock, (e) any Indebtedness to any employee of WCI or any of 
its Subsidiaries, (f) any liability for federal, state, local or other taxes 
owed or owing by WCI or (g) any trade payables of WCI. Senior Indebtedness of 
WCI will also include interest accruing subsequent to events of bankruptcy of 
WCI and its Subsidiaries at the rate provided for in the document governing 
such Senior Indebtedness, whether or not such interest is an allowed claim 
enforceable against the debtor in a bankruptcy case under federal bankruptcy 
law. 

    "Designated Senior Indebtedness" as defined under the Indenture means the 
1995 Senior Notes, the 1997 Senior Notes, the Equipment Note Guarantees and 
any Indebtedness constituting Senior Indebtedness of WCI that, at the date of 
determination, has an aggregate principal amount of at least $25.0 million 
and that is specifically designated by WCI in the instrument creating or 
evidencing such Senior Indebtedness as "Designated Senior Indebtedness." 

    The Indenture specifically designates that the Notes rank pari passu with 
the Convertible Notes. 

Same-Day Payment

    The Indenture requires that payments in respect of Notes (including 
principal, premium and interest) be made by wire transfer of immediately 
available funds to the accounts specified by the Holders thereof or, if no 
such account is specified, by mailing a check to each such Holder's 
registered address. 

Registration Rights

    The Registration Statement of which this Prospectus forms a part, has 
been filed by WCI pursuant to the Registration Agreement.  Under the terms of 
the Registration Agreement, the Company will be entitled to close the 
Exchange Offer 30 days after the commencement thereof provided that it has 
accepted all Old Notes theretofore validly tendered in accordance with the 
terms of such Exchange Offer.   After consummation of the Exchange Offer, the 
Company will have no further obligation to make any other such exchange 
offers.

Repurchase of Notes Upon a Change of Control

    WCI must commence, within 30 days of the occurrence of a Change of 
Control, and consummate an Offer to Purchase for all the Notes then 
outstanding, at a purchase price equal to 101% of the Accumulated Amount of 
such Notes on the date of purchase, plus accrued and unpaid interest (if any) 
on such Accumulated Amount to the date of purchase. Prior to the mailing of 
the notice to Holders of Notes commencing such Offer to Purchase, but in any 
event within 30 days following any Change of Control, WCI covenants to (i) 
repay in full all indebtedness of WCI that would prohibit the repurchase of 
the Notes pursuant to such Offer to Purchase or (ii) obtain any requisite 
consents under instruments governing any such indebtedness of WCI to permit 
the repurchase of the Notes. WCI shall first comply with the covenant in the 
preceding sentence before it shall purchase Notes pursuant to the "Repurchase 
of Notes upon a Change of Control" covenant. 

    Under the terms of the Indenture, WCI may not repurchase any Notes or any 
other subordinated indebtedness, including the Convertible Notes, pursuant to 
this covenant until WCI has repurchased all of the 1995 Senior Notes and the 
1997 Senior Notes and has caused each of WEC and WEC II to repurchase all of 
the WEC Notes and WEC II Notes, respectively, tendered pursuant to any Offer 
to Purchase as a result of such Change of Control. However, if WCI is unable 
to repay or cause repayment of all of the indebtedness that would prohibit 
repurchase of the Notes or is unable to obtain the consents of the holders of 
indebtedness, if any, outstanding at the time of a Change of Control whose 
consent would be so required to permit the repurchase of Notes or otherwise 
fails to purchase any Notes validly tendered, then WCI will have breached 
such covenant. This breach will constitute an Event of Default under the 
Indenture if it continues for a period of 30 consecutive days after written 
notice is given to WCI by the Trustee or the Holders of at least 25% in 
aggregate principal amount of the outstanding Notes, the 1995 Senior Notes, 
the 1997 Senior Notes, the WEC Notes or 

                                       42
<PAGE>

the WEC II Notes, as the case may be. In addition, the failure by WCI to 
repurchase Notes at the conclusion of the Offer to Purchase will constitute 
an Event of Default without any waiting period or notice requirements. 

    There can be no assurance that WCI, WEC and/or WEC II will have 
sufficient funds available at the time of any Change of Control to make any 
debt payment (including repurchases of Notes) required by the foregoing 
covenant (as well as may be contained in other securities of WCI, WEC and WEC 
II which might be outstanding at the time). The above covenant requiring WCI 
to repurchase the Notes will, unless the consents referred to above are 
obtained, require WCI, WEC and WEC II to repay all indebtedness then 
outstanding which by its terms would prohibit such Note repurchase, either 
prior to or concurrently with such Note repurchase. 

Covenants

    The Indenture contains covenants including, among others, the following:

    Limitation on Indebtedness

    (a)  WCI will not, and will not permit any of its Restricted Subsidiaries 
to, Incur any Indebtedness (other than the Notes and Indebtedness existing on 
the Issue Date); provided, however, that WCI may Incur Indebtedness if, after 
giving effect to the Incurrence of such Indebtedness and the receipt and 
application of the proceeds therefrom, the Indebtedness to EBITDA Ratio would 
be greater than zero and less than 5:1. 

    Notwithstanding the foregoing, WCI and any Restricted Subsidiary (except 
as specified below) may Incur each and all of the following: (i) Indebtedness 
of WCI outstanding at any time in an aggregate principal amount not to exceed 
$125.0 million, less any amount of Indebtedness Incurred pursuant to this 
clause (i) and permanently repaid as provided under "--Limitation on Asset 
Sales" below; (ii) Indebtedness (A) to WCI evidenced by an unsubordinated 
promissory note or (B) to any of its Restricted Subsidiaries; provided, 
however, that any event which results in any such Restricted Subsidiary 
ceasing to be a Restricted Subsidiary or any subsequent transfer of such 
Indebtedness (other than to WCI or another Restricted Subsidiary) shall be 
deemed, in each case, to constitute an Incurrence of such Indebtedness not 
permitted by this clause (ii); (iii) Indebtedness issued in exchange for, or 
the net proceeds of which are used to refinance or refund, then outstanding 
Indebtedness, other than Indebtedness Incurred under clause (i), (ii), (v), 
(vi) or (viii) of this paragraph, and any refinancings thereof in an amount 
not to exceed the amount so refinanced or refunded (plus premiums, accrued 
interest, fees and expenses); provided, however, that Indebtedness the 
proceeds of which are used to refinance or refund the Notes or Indebtedness 
that is pari passu with, or subordinated in right of payment to, the Notes 
shall only be permitted under this clause (iii) if (A) in case the Notes are 
refinanced in part or the Indebtedness to be refinanced is pari passu with 
the Notes, such new Indebtedness, by its terms or by the terms of any 
agreement or instrument pursuant to which such new Indebtedness is 
outstanding, is expressly made pari passu with, or subordinate in right of 
payment to, the remaining Notes, (B) in case the Indebtedness to be 
refinanced is subordinated in right of payment to the Notes, such new 
Indebtedness, by its terms or by the terms of any agreement or instrument 
pursuant to which such new Indebtedness is outstanding, is expressly made 
subordinate in right of payment to the Notes, at least to the extent that the 
Indebtedness to be refinanced is subordinated to the Notes, and (C) such new 
Indebtedness, determined as of the date of Incurrence of such new 
Indebtedness, does not mature prior to the Stated Maturity of the 
Indebtedness to be refinanced or refunded, and the Average Life of such new 
Indebtedness is at least equal to the remaining Average Life of the 
Indebtedness to be refinanced or refunded; provided further, however, that in 
no event may Indebtedness of WCI be refinanced by means of any Indebtedness 
of any Restricted Subsidiary of WCI pursuant to this clause (iii); (iv) 
Indebtedness (A) in respect of performance, surety or appeal bonds provided 
in the ordinary course of business, (B) under Currency Agreements and 
Interest Rate Agreements; provided, however, that such agreements do not 
increase the Indebtedness of the obligor outstanding at any time other than 
as a result of fluctuations in foreign currency exchange rates or interest 
rates or by reason of fees, indemnities and compensation payable thereunder, 
and (C) arising from agreements providing for indemnification, adjustment of 
purchase price or similar obligations, or from Guarantees or letters of 
credit, surety bonds or performance bonds securing any obligations of WCI or 
any of the Restricted Subsidiaries pursuant to such agreements, in any case 
Incurred in connection with the disposition of any business, assets or 
Restricted Subsidiary of WCI (other than Guarantees of Indebtedness Incurred 
by any Person acquiring all or any portion of such business, assets or 
Restricted Subsidiary of WCI for the purpose of financing such acquisition), 
in a principal amount not to exceed the gross proceeds actually received by 
WCI or any Restricted Subsidiary in connection with such disposition; (v) 
Indebtedness of WCI not to exceed, at any one time outstanding, two times the 
Net Cash Proceeds received by WCI from and after October 23, 

                                   43
<PAGE>

1995 from the issuance and sale of its Capital Stock (other than Redeemable 
Stock and Preferred Stock that provides for the payment of dividends in 
cash); provided, however, that such Indebtedness (x) does not mature prior to 
the Stated Maturity of the Notes and has an Average Life longer than the 
Notes and (y) is pari passu with or subordinated to the Notes at least to the 
extent that the Notes are subordinated to Senior Indebtedness; (vi) 
Indebtedness of any Restricted Subsidiary Incurred pursuant to any credit 
agreement of such Restricted Subsidiary in effect on the Issue Date (and 
refinancings thereof), up to the amount of the commitment under such credit 
agreement on the Issue Date; (vii) Indebtedness to the extent such 
Indebtedness is secured by Liens which are purchase money or other Liens upon 
equipment or inventory acquired or held by WCI or any of its Restricted 
Subsidiaries taken or obtained by (A) the seller or lessor of such equipment 
or inventory to secure all or a part of the purchase price or lease payments 
therefor or (B) the person who makes advances or incurs obligations, thereby 
giving value to WCI to enable it to purchase or acquire rights in such 
equipment or inventory, to secure the repayment of all or a part of the 
advances so made or obligations so incurred; provided, however, that such 
Liens do not extend to or cover any property or assets of WCI or any 
Restricted Subsidiary other than the equipment or inventory acquired; (viii) 
Indebtedness of any Restricted Subsidiary not to exceed, at any one time 
outstanding, 80% of the accounts receivable net of reserves and allowances 
for doubtful accounts, determined in accordance with GAAP, of such Restricted 
Subsidiary and its Restricted Subsidiaries (without duplication); provided, 
however, that such Indebtedness is not Guaranteed by WCI or any of its 
Restricted Subsidiaries; and (ix) Indebtedness of WCI, to the extent the 
proceeds thereof are immediately used to purchase the 1995 Notes or  the 1997 
Notes or the Notes tendered in an Offer to Purchase made as a result of a 
Change of Control. 

    (b)  For purposes of determining any particular amount of Indebtedness 
under this "Limitation on Indebtedness" covenant, Guarantees, Liens or 
obligations with respect to letters of credit supporting Indebtedness 
otherwise included in the determination of such particular amount shall not 
be included. For purposes of determining compliance with this "Limitation on 
Indebtedness" covenant, in the event that an item of Indebtedness meets the 
criteria of more than one of the types of Indebtedness described in the above 
clauses, WCI, in its sole discretion, shall classify such item of 
Indebtedness and only be required to include the amount and type of such 
Indebtedness in one of such clauses. 

    (c)  WCI will not, and will not permit any Restricted Subsidiary to, 
Incur any Guarantee of Indebtedness of any Unrestricted Subsidiary. 

    Limitation on Senior Subordinated Indebtedness

    WCI will not (i) Incur any Indebtedness, other than the Notes, that is 
expressly made subordinated in right of payment to any Senior Indebtedness of 
WCI unless such Indebtedness, by its terms and by the terms of any agreement 
or instrument pursuant to which such Indebtedness is outstanding is expressly 
made pari passu with, or subordinate in right of payment to, the Notes 
pursuant to provisions substantially similar to those contained in the 
Indenture; provided, however, that the foregoing limitation shall not apply 
to distinctions between categories of Senior Indebtedness of WCI that exist 
by reason of any Liens or Guarantees arising or created in respect of some 
but not all Senior Indebtedness of WCI or (ii) Incur any Indebtedness secured 
by a Lien if such Indebtedness is not Senior Indebtedness of WCI, unless 
contemporaneously therewith effective provision is made to secure the Notes 
equally and ratably with such secured Indebtedness for so long as such 
secured Indebtedness is secured by a Lien. The Indenture provides that the 
Notes are pari passu with the Convertible Notes. 

    Limitation on Restricted Payments

    WCI will not, and will not permit any Restricted Subsidiary to, directly 
or indirectly, (i) declare or pay any dividend or make any distribution on 
its Capital Stock (other than dividends or distributions payable solely in 
shares of its or such Restricted Subsidiary's Capital Stock (other than 
Redeemable Stock) held by such holders or in options, warrants or other 
rights to acquire such shares of Capital Stock) other than such Capital Stock 
held by WCI or any of its Restricted Subsidiaries (and other than pro rata 
dividends or distributions on Common Stock of Restricted Subsidiaries), (ii) 
repurchase, redeem, retire or otherwise acquire for value any shares of 
Capital Stock of WCI (including options, warrants or other rights to acquire 
such shares of Capital Stock) held by Persons other than any Wholly Owned 
Restricted Subsidiaries of WCI, (iii) make any voluntary or optional 
principal payment, or voluntary or optional redemption, repurchase, 
defeasance, or other acquisition or retirement for value, of Indebtedness of 
WCI that is subordinated in right of payment to the Note Guarantee or (iv) 
make any Investment, other than a Permitted Investment, in any Person (such 

                                  44
<PAGE>

payments or any other actions described in clauses (i) through (iv) being 
collectively "Restricted Payments") if, at the time of, and after giving 
effect to, the proposed Restricted Payment: (A) a Default or Event of Default 
shall have occurred and be continuing, (B) except with respect to any 
Investment (other than an Investment consisting of the designation of a 
Restricted Subsidiary as an Unrestricted Subsidiary), WCI could not Incur at 
least $1.00 of Indebtedness under the first paragraph of the "Limitation on 
Indebtedness" covenant or (C) the aggregate amount expended for all 
Restricted Payments (the amount so expended, if other than in cash, to be 
determined in good faith by the Board of Directors, whose determination shall 
be conclusive and evidenced by a Board Resolution) after the Closing Date 
shall exceed the sum of (1) 50% of the aggregate amount of the Adjusted 
Consolidated Net Income (or, if the Adjusted Consolidated Net Income is a 
loss, minus 100% of such amount) (determined by excluding income resulting 
from transfers of assets by WCI or a Restricted Subsidiary to an Unrestricted 
Subsidiary) accrued on a cumulative basis during the period (taken as one 
accounting period) beginning on the first day of the fiscal quarter 
immediately following the Closing Date and ending on the last day of the last 
fiscal quarter preceding the Transaction Date for which reports have been 
filed pursuant to "--SEC Reports and Reports to Holders" plus (2) the 
aggregate Net Cash Proceeds received by WCI after the Closing Date from the 
issuance and sale permitted by the Indentures of its Capital Stock (other 
than Redeemable Stock) to a Person who is not a Subsidiary of WCI, or from 
the issuance to a Person who is not a Subsidiary of WCI of any options, 
warrants or other rights to acquire Capital Stock of WCI (in each case, 
exclusive of any convertible Indebtedness, Redeemable Stock or any options, 
warrants or other rights that are redeemable at the option of the holder, or 
are required to be redeemed, prior to the Stated Maturity of the 1997 Senior 
Notes and the Notes) plus (3) an amount equal to the net reduction in 
Investments (other than reductions in Permitted Investments and other than 
reductions in Investments made pursuant to clauses (vi) or (vii) of the 
second paragraph of this "Limitation on Restricted Payments" covenant) in any 
Person resulting from payments of interest on Indebtedness, dividends, 
repayments of loans or advances, or other transfers of assets, in each case 
to WCI or any Restricted Subsidiary (except to the extent any such payment is 
included in the calculation of Adjusted Consolidated Net Income), or from 
redesignations of Unrestricted Subsidiaries as Restricted Subsidiaries 
(valued in each case as provided in the definition of "Investments"), not to 
exceed the amount of Investments previously made by WCI and its Restricted 
Subsidiaries in such Person. 

    The foregoing provision shall not be violated by reason of: (i) the 
payment of any dividend within 60 days after the date of declaration thereof 
if, at said date of declaration, such payment would comply with the foregoing 
paragraph; (ii) the redemption, repurchase, defeasance or other acquisition 
or retirement for value of Indebtedness that is subordinated in right of 
payment to the Note Guarantee, including premium, if any, and accrued and 
unpaid interest, with the proceeds of, or in exchange for, Indebtedness 
Incurred under clause (iii) of the second paragraph of the covenant described 
under "--Limitation on Indebtedness;" (iii) the repurchase, redemption or 
other acquisition of Capital Stock of WCI (or options, warrants or other 
rights to acquire such Capital Stock) in exchange for, or out of the proceeds 
of a substantially concurrent sale of, shares of Capital Stock or options, 
warrants or other rights to acquire such Capital Stock (in each case other 
than Redeemable Stock) of WCI; (iv) the making of any other Restricted 
Payment made by exchange for, or out of the proceeds of, a substantially 
concurrent sale of, shares of the Capital Stock or options, warrants or other 
rights to acquire such Capital Stock (in each case other than Redeemable 
Stock) of WCI; (v) payments or distributions, in the nature of satisfaction 
of dissenters' rights, pursuant to or in connection with a consolidation, 
merger or transfer of assets that complies with the provisions of the 
Indenture applicable to mergers, consolidations and transfers of all or 
substantially all of the property and assets of WCI; (vi) Investments, not to 
exceed $15 million at any one time outstanding; (vii) Investments, not to 
exceed $15 million at any one time outstanding, in entities, substantially 
all of the assets of which consist of Telecommunications Assets; (viii) (A) 
cash payments in lieu of the issuance of fractional shares of Common Stock 
upon conversion (including mandatory conversion) of the Convertible Notes 
provided for in the Convertible Notes Indenture and (B) cash payments on the 
Convertible Notes required to be made under the provisions of the Convertible 
Notes Indenture that relate to repurchases of Convertible Notes upon a change 
of control and that relate to limitations on sales of assets; (ix) cash 
payments in lieu of the issuance of fractional shares of Common Stock of WCI 
upon conversion of any class of Preferred Stock of WCI; provided, however, 
that this exception shall not be available with respect to more than two such 
conversions with respect to any such class of Preferred Stock by any given 
Affiliate of WCI; and (x) Investments in entities that directly (or 
indirectly through subsidiaries) own licenses granted by the FCC or any other 
governmental entity with authority to grant telecommunications licenses; 
provided, however, that, in each case WCI or a Restricted Subsidiary shall, 
at the time of making such Investment, have an active role in the management 
or operation of such entity and in the provision of telecommunications 
services by such entity; provided, however, that, except in the case of 
clauses (i) and (iii) of this paragraph, no Default or Event of Default shall 
have occurred and be continuing or occur as a consequence of the actions or 
payments set forth herein. Any Investments made other than in cash shall be 
valued, in good faith, by the Board of Directors. Any Investment made 
pursuant to clause (vi) or (vii) of this paragraph shall be deemed 

                                  45
<PAGE>

to be no longer outstanding (and repaid in full) if and when the Person in 
which such Investment is made becomes a Restricted Subsidiary of WCI. 

    Each Restricted Payment permitted pursuant to the preceding paragraph 
(other than the Restricted Payment referred to in clause (ii) thereof), and 
the Net Cash Proceeds from any issuance and sale of Capital Stock referred to 
in clauses (iii) or (iv) shall be included in calculating whether the 
conditions of clause (C) of the first paragraph of this "Limitation on 
Restricted Payments" covenant have been met with respect to any subsequent 
Restricted Payments. In the event the proceeds of an issuance of Capital 
Stock of WCI are used for the redemption, repurchase or other acquisition of 
the Notes or Indebtedness that is pari passu with the Notes, then the Net 
Cash Proceeds of such issuance shall be included in clause (C) of the first 
paragraph of this "Limitation on Restricted Payments" covenant only to the 
extent such proceeds are not used for such redemption, repurchase or other 
acquisition of Indebtedness. 

    Limitation on Dividend and Other Payment Restrictions Affecting 
    Restricted Subsidiaries

    WCI will not, and will not permit any Restricted Subsidiary to, create or 
otherwise cause or suffer to exist or become effective any consensual 
encumbrance or restriction of any kind on the ability of any Restricted 
Subsidiary to (i) pay dividends or make any other distributions permitted by 
applicable law on any Capital Stock of such Restricted Subsidiary owned by 
WCI or any other Restricted Subsidiary, (ii) pay any Indebtedness owed to WCI 
or any other Restricted Subsidiary that owns, directly or indirectly, any 
Capital Stock of such Restricted Subsidiary, (iii) make loans or advances to 
WCI or any other Restricted Subsidiary that owns, directly or indirectly, any 
Capital Stock of such Restricted Subsidiary or (iv) transfer any of its 
property or assets to WCI or any other Restricted Subsidiary that owns, 
directly or indirectly, any Capital Stock of such Restricted Subsidiary. 

    The foregoing provisions shall not prohibit any encumbrances or 
restrictions: (i) existing on the Issue Date in any agreement in effect on 
the Issue Date, and any extensions, refinancings, renewals or replacements of 
such agreements; provided, however, that the encumbrances and restrictions in 
any such extensions, refinancings, renewals or replacements are no less 
favorable in any material respect to the Holders than those encumbrances or 
restrictions that are then in effect and that are being extended, refinanced, 
renewed or replaced; (ii) existing under or by reason of applicable law; 
(iii) existing with respect to any Person or the property or assets of such 
Person acquired by WCI or any Restricted Subsidiary, at the time of such 
acquisition and not incurred in contemplation thereof, which encumbrances or 
restrictions are not applicable to any Person or the property or assets of 
any Person other than such Person or the property or assets of such Person so 
acquired; (iv) in the case of clause (iv) of the first paragraph of this 
"Limitation on Dividend and Other Payment Restrictions Affecting Restricted 
Subsidiaries" covenant, (A) that restrict in a customary manner the 
subletting, assignment or transfer of any property or asset that is a lease, 
license, conveyance or contract or similar property or asset, (B) existing by 
virtue of any transfer of, agreement to transfer, option or right with 
respect to, or Lien on, any property or assets of WCI or any Restricted 
Subsidiary not otherwise prohibited by the Indenture or (C) arising or agreed 
to in the ordinary course of business, not relating to any Indebtedness, and 
that do not, individually or in the aggregate, detract from the value of 
property or assets of WCI or any Restricted Subsidiary in any manner material 
to WCI or any Restricted Subsidiary; or (v) with respect to a Restricted 
Subsidiary and imposed pursuant to an agreement that has been entered into 
for the sale or disposition of all or substantially all of the Capital Stock 
of, or property and assets of, such Restricted Subsidiary. Nothing contained 
in this "Limitation on Dividend and Other Payment Restrictions Affecting 
Restricted Subsidiaries" covenant shall prevent WCI or any Restricted 
Subsidiary from (i) restricting the sale or other disposition of property or 
assets of WCI or any of its Restricted Subsidiaries that secure Indebtedness 
of WCI or any of its Restricted Subsidiaries or (ii) creating, incurring, 
assuming or suffering to exist any Liens otherwise permitted pursuant to the 
1997 Senior Notes Indenture as in effect on the Closing Date. 

    Limitation on the Issuance and Sale of Capital Stock of Restricted 
Subsidiaries

    WCI will not sell, and will not permit any Restricted Subsidiary, 
directly or indirectly, to issue or sell any shares of Capital Stock of a 
Restricted Subsidiary (including options, warrants or other rights to 
purchase shares of such Capital Stock) except (i) to WCI or a Wholly Owned 
Restricted Subsidiary, (ii) issuances or sales to foreign nationals of shares 
of Capital Stock of foreign Restricted Subsidiaries, to the extent required 
by applicable law, (iii) if, immediately after giving effect to such issuance 
or sale, such Restricted Subsidiary would no longer constitute a Restricted 
Subsidiary or (iv) issuances or sales of Common Stock of Restricted 
Subsidiaries, other than the Telecommunications Subsidiaries, if within six 
months of each such issuance or sale, WCI or such Restricted Subsidiary 
applies an amount not less than the                                           

                                   46 
<PAGE>

Net Cash Proceeds thereof (if any) in accordance with clause (A) or (B) of 
the first paragraph of the "Limitation on Asset Sales" covenant described 
below. 

    Limitation on Issuances of Guarantees by Restricted Subsidiaries

    WCI will not permit any Restricted Subsidiary, directly or indirectly, to 
Guarantee any Indebtedness of WCI ("Guaranteed Indebtedness"), unless (i) 
such Restricted Subsidiary simultaneously executes and delivers a 
supplemental indenture to the Indenture providing for a Guarantee (a 
"Subsidiary Guarantee") of payment of the Notes by such Restricted Subsidiary 
and (ii) such Restricted Subsidiary waives and will not in any manner 
whatsoever claim or take the benefit or advantage of, any rights of 
reimbursement, indemnity or subrogation or any other rights against WCI or 
any other Restricted Subsidiary as a result of any payment by such Restricted 
Subsidiary under its Subsidiary Guarantee; provided, however, that this 
paragraph shall not be applicable to any Guarantee of any Restricted 
Subsidiary that (x) existed at the time such Person became a Restricted 
Subsidiary and (y) was not Incurred in connection with, or in contemplation 
of, such Person becoming a Restricted Subsidiary. If the Guaranteed 
Indebtedness is (A) pari passu with the Notes, then the Guarantee of such 
Guaranteed Indebtedness shall be pari passu with, or subordinated to, the 
Subsidiary Guarantee or (B) subordinated to the Notes, then the Guarantee of 
such Guaranteed Indebtedness shall be subordinated to the Subsidiary 
Guarantee at least to the extent that the Guaranteed Indebtedness is 
subordinated to the Notes. 

    Notwithstanding the foregoing, any Subsidiary Guarantee by a Restricted 
Subsidiary shall provide by its terms that it shall be automatically and 
unconditionally released and discharged upon (i) any sale, exchange or 
transfer, to any Person not an Affiliate of WCI of all of WCI's and each 
Restricted Subsidiary's Capital Stock in, or all or substantially all the 
assets of, such Restricted Subsidiary (which sale, exchange or transfer is 
not prohibited by the Indenture) or (ii) the release or discharge of the 
Guarantee which resulted in the creation of such Subsidiary Guarantee, except 
a discharge or release by or as a result of payment under such Guarantee. 

    Limitation on Transactions with Shareholders and Affiliates

    WCI will not, and will not permit any Restricted Subsidiary to, directly 
or indirectly, enter into, renew or extend any transaction (including, 
without limitation, the purchase, sale, lease or exchange of property or 
assets, or the rendering of any service) with any holder (or any Affiliate of 
such holder) of 5% or more of any class of Capital Stock of WCI or with any 
Affiliate of WCI or any Restricted Subsidiary, except upon fair and 
reasonable terms no less favorable to WCI or such Restricted Subsidiary than 
could be obtained, at the time of such transaction or, if such transaction is 
pursuant to a written agreement, at the time of the execution of the 
agreement providing therefor, in a comparable arm's-length transaction with a 
Person that is not such a holder or an Affiliate. 

    The foregoing limitation does not limit, and shall not apply to (i) 
transactions (A) approved by a majority of the disinterested members of the 
Board of Directors or (B) for which WCI or a Restricted Subsidiary delivers 
to the Trustee a written opinion of a nationally recognized investment 
banking firm stating that the transaction is fair to WCI or such Restricted 
Subsidiary from a financial point of view; (ii) any transaction solely 
between WCI and any of its Wholly Owned Restricted Subsidiaries or solely 
between Wholly Owned Restricted Subsidiaries; (iii) the payment of reasonable 
fees to directors of WCI who are not employees of WCI; (iv) any payments or 
other transactions pursuant to any tax-sharing agreement between WCI and any 
other Person with which WCI files a consolidated tax return or with which WCI 
is part of a consolidated group for tax purposes; or (v) any Restricted 
Payments not prohibited by the covenant described under "--Limitation on 
Restricted Payments" (other than pursuant to clause (iv) of the definition of 
"Permitted Investment" or clause (vi) of the second paragraph of such 
covenant). Notwithstanding the foregoing, any transaction covered by the 
first paragraph of this "Limitation on Transactions with Shareholders and 
Affiliates" covenant and not covered by clauses (ii) through (iv) of this 
paragraph, the aggregate amount of which exceeds $250,000 in value, must be 
approved or determined to be fair in the manner provided for in clause (i)(A) 
or (B) above. 

    Limitation on Asset Sales

    WCI will not, and will not permit any Restricted Subsidiary to, 
consummate any Asset Sale, unless (i) the consideration received by WCI or 
such Restricted Subsidiary is at least equal to the fair market value of the 
assets sold or disposed of and (ii) at least 85% of the consideration 
received consists of cash or Temporary Cash Investments. In the event and to 
the extent that the Net Cash Proceeds received by WCI or its Restricted 
Subsidiaries from one or more Asset 

                                    47
<PAGE>

Sales occurring on or after the Closing Date in any period of 12 consecutive 
months exceed 10% of Adjusted Consolidated Net Tangible Assets (determined as 
of the date closest to the commencement of such 12-month period for which a 
consolidated balance sheet of WCI and its Subsidiaries has been prepared), 
then WCI shall or shall cause the relevant Restricted Subsidiary to (i) 
within six months after the date Net Cash Proceeds so received exceed 10% of 
Adjusted Consolidated Net Tangible Assets (A) apply an amount equal to such 
excess Net Cash Proceeds to permanently repay unsubordinated Indebtedness of 
WCI, or Indebtedness of any Restricted Subsidiary, in each case owing to a 
Person other than WCI or any of its Restricted Subsidiaries or (B) invest an 
equal amount, or the amount not so applied pursuant to clause (A) (or enter 
into a definitive agreement committing to so invest within six months after 
the date of such agreement), in property or assets of a nature or type or 
that are used in a business (or in a company having property and assets of a 
nature or type, or engaged in a business) similar or related to the nature or 
type of the property and assets of, or the business of, WCI and its 
Restricted Subsidiaries existing on the date of such investment (as 
determined in good faith by the Board of Directors, whose determination shall 
be conclusive and evidenced by a Board Resolution) and (ii) apply (no later 
than the end of the six-month period referred to in clause (i)) such excess 
Net Cash Proceeds (to the extent not applied pursuant to clause (i)) as 
provided in the following paragraph of this "Limitation on Asset Sales" 
covenant. The amount of such excess Net Cash Proceeds required to be applied 
(or to be committed to be applied) during such six-month period as set forth 
in clause (i) of the preceding sentence and not applied as so required by the 
end of such period shall constitute "Excess Proceeds." 

    If, as of the first day of any calendar month, the aggregate amount of 
Excess Proceeds not theretofore subject to an Offer to Purchase pursuant to 
this "Limitation on Asset Sales" covenant totals at least $10.0 million, WCI 
must commence, not later than the 15th Business Day after the first day of 
such month, and consummate an Offer to Purchase from the Holders on a pro 
rata basis an aggregate principal amount of Notes equal to the Excess 
Proceeds on such date, at a purchase price equal to 101% of the Accumulated 
Amount of such Notes on the date of purchase, plus accrued and unpaid 
interest (if any) on such amount to the date of purchase; provided, however, 
that no Offer to Purchase shall be required to be commenced with respect to 
the Notes until the Business Day following the payment date with respect to 
the Offer to Purchase any 1997 Notes and need not be commenced if the Excess 
Proceeds remaining after application thereof to the 1997 Notes purchased in 
such Offer to Purchase applicable thereto are less than $10,000,000; provided 
further, however, that no Notes may be purchased under this covenant unless 
WCI shall have purchased all 1997 Notes tendered pursuant to the Offer to 
Purchase applicable thereto. 

    Because of similar requirements in the Indentures governing the 1995 
Notes and the 1997 Notes, WCI may not have Excess Proceeds from an Asset Sale 
to be able to comply with the foregoing requirements. 

SEC Reports and Reports to Holders

    Whether or not WCI is required to file reports with the SEC, if any Notes 
are outstanding, WCI shall file with the SEC all such reports and other 
information as it would be required to file with the SEC by Sections 13(a) or 
15(d) under the Exchange Act. See "Available Information." WCI shall supply 
the Trustee and each Holder of Notes, as the case may be, or shall supply to 
the relevant Trustee for forwarding to each such Holder, without cost to such 
Holder, copies of such reports or other information. 

Consolidation, Merger and Sale of Assets

    Under the terms of the Indenture, WCI shall not consolidate with, merge 
with or into, or sell, convey, transfer, lease or otherwise dispose of all or 
substantially all of its property and assets (as an entirety or substantially 
an entirety in one transaction or a series of related transactions) to, any 
Person (other than a consolidation or merger with or into a Wholly Owned 
Restricted Subsidiary with a positive net worth; provided, however, that, in 
connection with any such merger or consolidation, no consideration (other 
than Common Stock in the surviving Person or WCI) shall be issued or 
distributed to the stockholders of WCI) or permit any Person to merge with or 
into WCI unless: (i) WCI shall be the continuing Person, or the Person (if 
other than WCI) formed by such consolidation or into which WCI is merged or 
that acquired or leased such property and assets of WCI shall be a 
corporation organized and validly existing under the laws of the United 
States of America or any jurisdiction thereof and shall expressly assume, by 
a supplemental indenture, executed and delivered to the Trustee, all of the 
obligations of WCI on the Notes and under the Indenture; (ii) immediately 
after giving effect to such transaction, no Default or Event of Default shall 
have occurred and be continuing; (iii) immediately after giving effect to 
such transaction on a pro forma basis, WCI or any Person becoming the 
successor 

                                  48
<PAGE>

obligor of the Notes shall have a Consolidated Net Worth equal to or greater 
than the Consolidated Net Worth of WCI immediately prior to such transaction; 
(iv) immediately after giving effect to such transaction on a pro forma basis 
WCI, or any Person becoming the successor obligor of the Notes, could Incur 
at least $1.00 of Indebtedness under the first paragraph of the covenant 
described under "--Covenants--Limitation on Indebtedness;" and (v) WCI 
delivers to the Trustee an Officers' Certificate (attaching the arithmetical 
computations to demonstrate compliance with clauses (iii) and, if applicable, 
(iv)) and Opinion of Counsel, in each case stating that such consolidation, 
merger or transfer and such supplemental indenture complies with this 
provision and that all conditions precedent provided for herein relating to 
such transaction have been complied with; provided, however, that clauses 
(iii) and (iv) above do not apply if, in the good faith determination of the 
Board of Directors of WCI, whose determination shall be evidenced by a Board 
Resolution, the principal purpose of such transaction is to change the state 
of incorporation of WCI; provided further, however, that any such transaction 
shall not have as one of its purposes the evasion of the foregoing 
limitations. 

Events of Default

    The following events will be defined as "Events of Default" in the 
Indenture: (i) default in the payment of principal of (or premium, if any, 
on) any Note when the same becomes due and payable at maturity, upon 
acceleration, redemption or otherwise, whether or not such payment is 
prohibited by the provisions described above under "Ranking"; (ii) default in 
the payment of interest on any Note when the same becomes due and payable, 
and such default continues for a period of 30 days, whether or not such 
payment is prohibited by the provisions described above under "Ranking"; 
(iii) WCI defaults in the performance of or breaches any other covenant or 
agreement of WCI in the Indenture, or under the Notes, and such default or 
breach continues for a period of 30 consecutive days after written notice by 
the Trustee or the Holders of 25% or more in aggregate principal amount of 
the Notes; (iv) there occurs with respect to any issue or issues of 
Indebtedness of WCI or any Significant Subsidiary having an outstanding 
principal amount of $25.0 million or more in the aggregate for all such 
issues of all such Persons, whether such Indebtedness now exists or shall 
hereafter be created, (a) an event of default that has caused the holder 
thereof to declare such Indebtedness to be due and payable prior to its 
Stated Maturity and such Indebtedness has not been discharged in full or such 
acceleration has not been rescinded or annulled within 30 days of such 
acceleration and/or (b) the failure to make a principal payment at the final 
(but not any interim) fixed maturity and such defaulted payment shall not 
have been made, waived or extended within 30 days of such payment default; 
(v) any final judgment or order (not covered by insurance) for the payment of 
money in excess of $25.0 million in the aggregate for all such final 
judgments or orders against all such Persons (treating any deductibles, 
self-insurance or retention as not so covered) shall be rendered against WCI 
or any Significant Subsidiary and shall not be paid or discharged, and there 
shall be any period of 60 consecutive days following entry of the final 
judgment or order that causes the aggregate amount for all such final 
judgments or orders outstanding and not paid or discharged against all such 
Persons to exceed $25.0 million during which a stay of enforcement of such 
final judgment or order, by reason of a pending appeal or otherwise, shall 
not be in effect; (vi) a court having jurisdiction in the premises enters a 
decree or order for (a) relief in respect of WCI or any Significant 
Subsidiary in an involuntary case under any applicable bankruptcy, insolvency 
or other similar law now or hereafter in effect, (b) appointment of a 
receiver, liquidator, assignee, custodian, trustee, sequestrator or similar 
official of WCI or any Significant Subsidiary or for all or substantially all 
of the property and assets of WCI or any Significant Subsidiary or (c) the 
winding up or liquidation of the affairs of WCI or any Significant Subsidiary 
and, in each case, such decree or order shall remain unstayed and in effect 
for a period of 60 consecutive days; or (vii) WCI or any Significant 
Subsidiary (a) commences a voluntary case under any applicable bankruptcy, 
insolvency or other similar law now or hereafter in effect, or consents to 
the entry of an order for relief in an involuntary case under any such law, 
(b) consents to the appointment of or taking possession by a receiver, 
liquidator, assignee, custodian, trustee, sequestrator or similar official of 
WCI or any Significant Subsidiary or for all or substantially all of the 
property and assets of WCI or any Significant Subsidiary or (c) effects any 
general assignment for the benefit of creditors. 

    If an Event of Default (other than an Event of Default specified in 
clause (vi) or (vii) above that occurs with respect to WCI and is continuing 
under the Indenture, the Trustee or the Holders of at least 25% in aggregate 
principal amount of the Notes then outstanding, by written notice to WCI (and 
to the Trustee if such notice is given by the Holders), may, and the Trustee 
at the request of such Holders shall, declare the principal of, premium, if 
any, and accrued interest, if any, on the Notes, to be immediately due and 
payable. Upon a declaration of acceleration, such principal, premium, if any, 
and accrued interest, if any, shall be immediately due and payable. In the 
event of a declaration of acceleration because an Event of Default set forth 
in clause (iv) above has occurred and is continuing, such declaration of 
acceleration shall be automatically rescinded and annulled if the event of 
default triggering such Event of Default pursuant to clause 

                                   49
<PAGE>

(iv) shall be remedied or cured by WCI or the relevant Significant Subsidiary 
or waived by the holders of the relevant Indebtedness within 60 days after 
the declaration of acceleration with respect thereto. If an Event of Default 
specified in clause (vi) or (vii) above occurs with respect to WCI, the 
principal of, premium, if any, and accrued interest, if any, on the Notes 
then outstanding shall ipso facto become and be immediately due and payable 
without any declaration or other act on the part of Trustee or any Holder. 
The Holders of at least a majority in principal amount of the outstanding 
Notes, by written notice to WCI and to the Trustee, may waive all past 
defaults and rescind and annul a declaration of acceleration and its 
consequences if (A) all existing Events of Default, other than the nonpayment 
of the principal of, premium, if any, and interest on the Notes that have 
become due solely by such declaration of acceleration, have been cured or 
waived and (B) the rescission would not conflict with any judgment or decree 
of a court of competent jurisdiction. For information as to the waiver of 
defaults, see "--Modification and Waiver." 

    The Holders of at least a majority in aggregate principal amount of the 
outstanding Notes may 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. However, the Trustee may refuse to follow any 
direction that conflicts with law or the Indenture, that may involve the 
Trustee in personal liability, or that the Trustee determines in good faith 
may be unduly prejudicial to the rights of Holders of Notes not joining in 
the giving of such direction and may take any other action it deems proper 
that is not inconsistent with any such direction received from Holders of 
Notes. A Holder may not pursue any remedy with respect to the Indenture or 
the Notes unless: (i) the Holder gives the Trustee written notice of a 
continuing Event of Default; (ii) the Holders of at least 25% in aggregate 
principal amount of outstanding Notes make a written request to the Trustee 
to pursue the remedy; (iii) such Holder or Holders offer the Trustee 
indemnity satisfactory to the Trustee against any costs, liability or 
expense; (iv) the Trustee does not comply with the request within 60 days 
after receipt of the request and the offer of indemnity; and (v) during such 
60-day period, the Holders of a majority in aggregate principal amount of the 
outstanding Notes do not give the Trustee a direction that is inconsistent 
with the request. However, such limitations do not apply to the right of any 
Holder of a Note to receive payment of the principal of, premium, if any, or 
interest on, such Note or to bring suit for the enforcement of any such 
payment, on or after the due date expressed in the Notes, which right shall 
not be impaired or affected without the consent of the Holder. 

    The Indenture will require certain officers of WCI to certify, on or 
before a date not more than 90 days after the end of each fiscal year, that a 
review has been conducted of the activities of WCI and its Restricted 
Subsidiaries' performance under the Indenture and that, to the best knowledge 
of such officer, WCI has fulfilled all obligations thereunder, or, if there 
has been a default in the fulfillment of any such obligation, specifying each 
such default and the nature and status thereof. WCI will also be obligated to 
notify the Trustee of any default or defaults in the performance of any 
covenants or agreements under the Indenture. 

Defeasance

    Defeasance and Discharge.  The Indenture will provide that WCI be deemed 
to have paid and will be discharged from any and all obligations in respect 
of the Notes on the 123rd day after the deposit referred to below, and the 
provisions of the Indenture will no longer be in effect with respect to the 
Notes (except for, among other matters, certain obligations to register the 
transfer or exchange of the Notes, to replace stolen, lost or mutilated 
Notes, to maintain paying agencies, to hold monies for payment in trust), if, 
among other things, (A) WCI has deposited with the Trustee, in trust, money 
and/or U.S. Government Obligations that through the payment of interest and 
principal in respect thereof in accordance with their terms will provide 
money in an amount sufficient to pay the principal of, premium, if any, and 
accrued interest on the Notes on the Stated Maturity of such payments or upon 
earlier optional redemption, in each case in accordance with the terms of the 
Indenture and the Notes, (B) WCI has delivered to the Trustee (i) either (x) 
an Opinion of Counsel to the effect that Holders will not recognize income, 
gain or loss for federal income tax purposes as a result of WCI's exercise of 
its option under this "Defeasance" provision and will be subject to federal 
income tax on the same amount and in the same manner and at the same times as 
would have been the case if such deposit, defeasance and discharge had not 
occurred, which Opinion of Counsel must be based upon (and accompanied by a 
copy of) a ruling of the Internal Revenue Service to the same effect unless 
there has been a change in applicable federal income tax law after the Issue 
Date such that a ruling is no longer required or (y) a ruling directed to the 
Trustee received from the Internal Revenue Service to the same effect as the 
aforementioned Opinion of Counsel and (ii) an Opinion of Counsel to the 
effect that the creation of the defeasance trust does not violate the 
Investment Company Act of 1940 and after the passage of 123 days following 
the deposit, the trust fund will not be subject to the effect of Section 547 
of the Bankruptcy Code or Section 15 of the New York Debtor and Creditor Law, 
(C) immediately after giving effect to such deposit on a pro forma basis, no 
Event of 

                                    50
<PAGE>

Default, or event that after the giving of notice or lapse of time or both 
would become an Event of Default, shall have occurred and be continuing on 
the date of such deposit or during the period ending on the 123rd day after 
the date of such deposit, and such deposit shall not result in a breach or 
violation of, or constitute a default under, any other agreement or 
instrument to which WCI is a party or by which WCI is bound, and (D) if at 
such time the Notes are listed on a national securities exchange, WCI has 
delivered to the Trustee an Opinion of Counsel to the effect that the Notes 
will not be delisted as a result of such deposit, defeasance and discharge. 

    Defeasance of Certain Covenants and Certain Events of Default.  The 
Indenture further provides that its provisions will no longer be in effect 
with respect to clauses (iii) and (iv) under "Consolidation, Merger and Sale 
of Assets" and all the covenants described herein under "Covenants," clause 
(c) under "--Events of Default" with respect to such covenants and clauses 
(iii) and (iv) under "Consolidation, Merger and Sale of Assets," and clauses 
(d) and (e) and, if applicable, (i) and (ii) under "--Events of Default" 
shall be deemed not to be Events of Default, the provisions described under 
"--Ranking" with respect to the assets held by the Trustee referred to below 
shall not apply, upon, among other things, the deposit with the Trustee, in 
trust, of money and/or U.S. Government Obligations that through the payment 
of interest and principal in respect thereof in accordance with their terms 
will provide money in an amount sufficient to pay the principal of, premium, 
if any, and accrued interest on the Notes on the Stated Maturity of such 
payments or upon earlier optional redemption, in each case in accordance with 
the terms of the Indenture and the Notes, the satisfaction of the provisions 
described in clauses (B)(ii), (C) and (D) of the preceding paragraph and the 
delivery by WCI to the Trustee of an Opinion of Counsel to the effect that, 
among other things, the Holders will not recognize income, gain or loss for 
federal income tax purposes as a result of such deposit and defeasance of 
certain covenants and Events of Default and will be subject to federal income 
tax on the same amount and in the same manner and at the same times as would 
have been the case if such deposit and defeasance had not occurred. 

    Defeasance and Certain Other Events of Default.  In the event WCI 
exercises its option to omit compliance with certain covenants and provisions 
of the Indenture with respect to the Notes as described in the immediately 
preceding paragraph and the Notes are declared due and payable because of the 
occurrence of an Event of Default that remains applicable, the amount of 
money and/or U.S. Government Obligations on deposit with the Trustee will be 
sufficient to pay amounts due on the Notes at the time of their Stated 
Maturity but may not be sufficient to pay amounts due on the Notes at the 
time of the acceleration resulting from such Event of Default. However, WCI 
will remain liable for such payments. 

Modification and Waiver

    Modifications and amendments of the Indenture may be made by WCI and the 
Trustee with the consent of the Holders of not less than a majority in 
aggregate principal amount of the outstanding Notes; provided, however, that 
no such modification or amendment may, without the consent of each Holder 
affected thereby, (i) change the Stated Maturity of the principal of, or any 
installment of interest on, any Note, (ii) reduce the principal amount of, or 
premium, if any, or interest on, any Note, (iii) change the place or currency 
of payment of principal of, or premium, if any, or interest on, any Note, 
(iv) impair the right to institute suit for the enforcement of any payment on 
or after the Stated Maturity (or, in the case of a redemption, on or after 
the Redemption Date) of any Note, (v) reduce the above-stated percentage of 
outstanding Notes the consent of whose Holders is necessary to modify or 
amend the Indenture, (vi) waive a default in the payment of principal of, 
premium, if any, or interest on the Notes or (vii) reduce the percentage or 
aggregate principal amount of outstanding Notes the consent of whose Holders 
is necessary for waiver of compliance with certain provisions of the 
Indenture or for waiver of certain defaults. 

    Without the consent of any Holder of the Notes, WCI and the Trustee may 
modify or amend the Indenture to cure any ambiguity, defect or inconsistency, 
to provide for the assumption by a successor company of WCI's obligations 
under the Indenture, to comply with the requirements of the Trust Indenture 
Act, to appoint a successor Trustee or to make any change that, in the 
opinion of the Board of Directors of WCI evidenced by a Board Resolution, 
does not materially and adversely affect the rights of any Holder. 

                                  51
<PAGE>

No Personal Liability of Incorporators, Stockholders, Officers, Directors or 
Employees

    The Indenture provides that no recourse for the payment of the principal 
of, premium, if any, or interest on any of the Notes or for any claim based 
thereon or otherwise in respect thereof, and no recourse under or upon any 
obligation, covenant or agreement of WCI in the Indenture, or in any of the 
Notes or because of the creation of any Indebtedness represented thereby, 
shall be had against any incorporator, stockholder, officer, director, 
employee or controlling person of WCI or of any successor Person thereof in 
such capacity. Each Holder, by accepting the Notes, waives and releases all 
such liability. 

Concerning the Trustee

    The Indenture provides that, except during the continuance of a Default, 
the Trustee will not be liable, except for the performance of such duties as 
are specifically set forth in such Indenture. If an Event of Default has 
occurred and is continuing, the Trustee will 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 WCI 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, however, that if the Trustee acquires any conflicting

defaults in the payment of the purchase price, any Note accepted for payment 
pursuant to the Offer to Purchase shall cease to accrue interest on and after 
the Payment Date; (v) that Holders electing to have a Note purchased pursuant 
to the Offer to Purchase will be required to surrender the Note together with 
the form entitled "Option of the Holder to Elect Purchase" on the reverse 
side thereof completed, to the Paying Agent at the address specified in the 
notice prior to the close of business on the Business Day immediately 
preceding the Payment Date; (vi) that Holders will be entitled to withdraw 
their election if the Paying Agent receives, not later than the close of 
business on the third Business Day immediately preceding the Payment Date, a 
telegram, facsimile transmission or letter setting forth the name of such 
Holder, the Accumulated Amount of Notes delivered for purchase and a 
statement that such Holder is withdrawing his election to have such Notes 
purchased; and (vii) that Holders whose Notes are being purchased only in 
part will be issued new Notes equal in Accumulated Amount (and accrued and 
unpaid interest) to the unpurchased portion thereof; provided, however, that 
each Note purchased and each new Note issued shall be in a principal amount 
of $1,000 or integral multiples thereof. On the Payment Date, WCI shall (i) 
accept for payment on a pro rata basis Notes or portions thereof tendered 
pursuant to an Offer to Purchase; (ii) deposit with the Paying Agent money 
sufficient to pay the purchase price of all Notes or portions thereof so 
accepted; and (iii) deliver, or cause to be delivered, to the Trustee all 
Notes or portions thereof so accepted together with an Officers' Certificate 
specifying the Notes or portions thereof accepted for payment by WCI. The 
Paying Agent shall promptly mail to the Holders of Notes so accepted for 
payment in an amount equal to the purchase price, and the Trustee shall 
promptly authenticate and mail to such Holders a new Note equal in principal 
amount to any unpurchased portion of the Note surrendered; provided, however, 
that each Note purchased and each new Note issued shall be in a principal 
amount of $1,000 or integral multiples thereof. WCI will publicly announce 
the results of an Offer to Purchase as soon as practicable after the Payment 
Date. The Trustee shall act as the Paying Agent for an Offer to Purchase. WCI

          CERTAIN UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

    The following is a summary of the material United States federal income 
tax consequences of the acquisition, ownership and disposition of the New 
Notes.  This summary is based on the Internal Revenue Code of 1986, as 
amended (the "Code"), existing and proposed Treasury regulations promulgated 
thereunder, and administrative and judicial interpretations thereof, all as 
in effect or proposed on the date hereof and all of which are subject to 
change, possibly with retroactive effect, or different interpretations.  This 
summary assumes that all of the New Notes will be held as capital assets 
(i.e., generally assets that are held for investment), within the meaning of 
Section 1221 of the Code, and will not be part of a straddle, a hedge or a 
conversion transaction, within the meaning of Section 1258 of the Code.  The 
discussion is for general information only, and does not address all of the 
tax consequences that may be relevant to particular purchasers in light of 
their personal circumstances, or to certain types of purchasers (such as 
certain financial institutions, insurance companies, tax-exempt entities or 
dealers in securities). Persons considering the exchange of 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 jurisdictions.

    As used in the summary which follows, the term "U.S. Holder" means a 
beneficial owner of New Notes 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, or (iii) 
otherwise subject to United States federal income taxation on a net income 
basis with respect to worldwide income. The term "Non-U.S. Holder" means a 
holder of New Notes, that is, for United States federal income tax purposes, 
not a U.S. Holder.

HOLDERS SHOULD CONSULT THEIR OWN TAX ADVISORS AS TO THE PARTICULAR TAX 
CONSEQUENCES TO THEM OF EXCHANGING THE Old Notes FOR New Notes AND 
PURCHASING, HOLDING AND DISPOSING OF THE New Notes, INCLUDING THE 
APPLICABILITY AND EFFECT OF ANY STATE, LOCAL OR FOREIGN TAX LAWS. 

Exchange for Old Notes

    The exchange by a holder of an Exchange Act Note for a New Note does not 
constitute a taxable exchange because the New Notes do not differ materially 
in kind or extent from the Old Notes.  Each New Note will be treated as 
having been originally issued at the time the Exchange Act Note exchanged 
therefor was originally issued.  The tax basis and holding period of each 
Exchance Act Note will carry over to the New Note issued in exchange of each 
Exchance Act Note.

Tax Consequences to U.S. Holders

    Original Issue Discount.  The Notes are being issued with original issue 
discount, as defined in the Code. The amount of original issue discount on a 
debt instrument, within the meaning of Section 1273 of the Code, is the 
excess (if any) of its "stated redemption price at maturity" over its issue 
price. The issue price of each of the Notes will be the respective offering 
price to the purchasers (not including any sales to a bond house, broker, or 
similar person or organization acting in the capacity of an underwriter, 
placement agent or wholesaler) at which a substantial amount of each of the 
Notes is sold. According to the Treasury Regulations, the issue price of the 
Notes does not change even if part of the issue is subsequently sold at a 
different price. The "stated redemption price at maturity" of a debt 
instrument is the sum of its principal amount plus all other payments 
required thereunder, other than payments of "qualified stated interest" 
(defined generally as stated interest that is unconditionally payable in cash 
or in property (other than the debt instruments of the Company) at least 
annually at a single fixed rate that appropriately takes into account the 
length of intervals between payments). Because interest on the Notes is not 
payable in cash until 2002, the stated interest on the Notes will not be 
treated as qualified stated interest, but will, for United States federal 
income tax purposes, be added to the stated redemption price at maturity of 
the Notes. As a result, the Notes will be treated as having been issued with 
original issue discount equal to the excess of their stated redemption price 
at maturity over their issue price. 

    Each U.S. Holder of a Note (regardless of whether such U.S. Holder is a 
cash or an accrual basis taxpayer) will be required to include in such U.S. 
Holder's gross income in each taxable year, in advance of the receipt of cash 
payments 
                                       62
<PAGE>

attributable to such income, that portion of the original issue discount, 
computed on a constant yield basis, attributable to each day during such 
taxable year on which the U.S. Holder held the Note. In general, under 
Section 1272 of the Code, the amount of original issue discount that a holder 
of a debt instrument must include in gross income for United States federal 
income tax purposes will be the sum of the daily portions of original issue 
discount with respect to such debt instrument for each day during the taxable 
year or portion of a taxable year in which such holder holds the debt 
instrument. The daily portion is determined under a constant yield method by 
allocating to each day of an accrual period a pro rata portion of an amount 
equal to the "adjusted issue price" of the debt instrument at the beginning 
of the accrual period multiplied by the yield to maturity of the debt 
instrument (stated in a manner appropriately taking into account the length 
of the accrual period). Accrual periods with respect to a Note may be of any 
length selected by the U.S. Holder and may vary in length over the term of 
the Note as long as (i) no accrual period is longer than one year and (ii) 
each scheduled payment of interest or principal on the Note occurs on either 
the final or first day of an accrual period. The yield to maturity of a debt 
instrument is the discount rate that, when applied to all payments due under 
the debt instrument produces a present value equal to the issue price of the 
debt instrument. The "adjusted issue price" is the issue price of the debt 
instrument increased by the accrued original issue discount for all prior 
accrual periods (and decreased by the amount of cash payments made in all 
prior accrual periods). 

    The Company will report annually to the Service and to record holders of 
the Notes the original issue discount accrued and the amount of interest paid 
during the calendar year. 

    U.S. Holders of Notes should be aware that, because of the above original 
issue discount rules, a U.S. Holder of a Note will be required for United 
States federal income tax purposes to include amounts in ordinary income in 
advance of the receipt of the cash attributable to such income. 

    Acquisition Premium.  If a U.S. Holder acquires a Note at a cost in 
excess of its "adjusted issue price" (as defined above) but less than its 
stated redemption price at maturity, such Note will have an acquisition 
premium to the extent of such excess. Under the acquisition premium rules of 
the Code and the Treasury Regulations promulgated thereunder, the amount of 
the original issue discount which such U.S. 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. 

    Market Discount.  If a U.S. Holder purchases Notes for an amount that is 
less than the "revised issue price" of the Notes at the time of acquisition, 
the amount of such difference will be treated as "market discount" for United 
States federal income tax purposes, unless such difference is less than a 
specified de minimis amount ("de minimis market discount"). The "revised 
issue price" is the original issue price of a Note plus the aggregate amount 
of previously accrued original issue discount without regard to any 
reductions for acquisition premium, less payments other than qualified stated 
interest. Under the market discount rules, a holder will be required to treat 
any principal payment on or any gain on the sale, exchange, retirement or 
other disposition of, Notes as ordinary income to the extent of the market 
discount which has not previously been included in income and is treated as 
having accrued on such Notes at the time of such payment or disposition. If a 
holder makes a gift of a Note, accrued market discount, if any, will be 
recognized as if such holder had sold such Note for a price equal to its fair 
market value. In addition, the holder may be required to defer, until the 
maturity of the Notes or the earlier disposition of the Notes in a taxable 
transaction, the deduction of a portion of the interest expense on any 
indebtedness incurred or continued to purchase or carry such Notes. 

    Any market discount will be considered to accrue on a straight-line basis 
during the period from the date of acquisition to the maturity date of the 
Notes, unless a holder elects to accrue market discount on a constant 
interest method. A holder of Notes may elect to include market discount in 
income currently as it accrues (on either a straight-line basis or constant 
interest method), in which the case rules described above regarding the 
deferral of interest deductions and ordinary income treatment of gain on 
disposition will not apply. This election to include market discount in 
income currently, once made, applies to all market discount obligations 
acquired on or after the first day of the first taxable year to which the 
election applies and may not be revoked without the consent of the Service. 

    Additional Interest or Payment on Notes.  Failure of the Company to 
register the Notes pursuant to an effective registration statement as 
described under "Description of the Notes--Registration Rights" will cause 
additional interest to accrue on the Notes in the manner described therein. 
In addition, upon a Change of Control, an additional amount would be payable 
in the event that a holder requires the Company to repurchase such holder's 
Notes, in the manner described under "Description of the Notes--Change of 
Control." Under Treasury Regulations, the possibility of any such additional 

                                       63

<PAGE>

interest or payment will not affect the accrual of original issue discount or 
the yield to maturity on the Notes unless, based on all the facts and 
circumstances as of the issue date, it is more likely than not that such 
additional interest or payment will be paid. The Company does not intend to 
treat the possibility of such additional interest or payment as affecting the 
computation of original issue discount or yield to maturity. If a holder of a 
Note becomes entitled to additional interest or payment, for purposes of 
determining the accrual of original issue discount, the yield to maturity of 
the Notes will be redetermined by treating the Notes as reissued on the date 
it is determined that such additional interest or payment will be required to 
be paid, for an amount equal to its adjusted issue price on such date. 

    Exchange Offer.  The exchange of Notes for Exchange Notes pursuant to the 
Registered Exchange Offer should not be a taxable exchange. Consequently, a 
U.S. Holder should not recognize taxable income or loss as a result of 
exchanging a Note for an Exchange Note pursuant to the Registered Exchange 
Offer. The holding period of an Exchange Note will include the holding period 
of the Note and the basis of the Exchange Note will be the same as the basis 
of the Note immediately before the exchange. 

    The Company will be required to pay additional cash interest on the Notes 
if it fails to comply with certain of its obligations under the Registration 
Rights Agreement. See "Description of the Notes--Registration Rights." Such 
additional interest should be taxable to a U.S. Holder as ordinary income at 
the time it accrues or is received, in accordance with each such U.S. 
Holder's method of tax accounting. It is possible, however, that the Service 
may take a different position, in which case a U.S. Holder might be required 
to include such additional interest in income as its accrues or becomes fixed 
(regardless of such holder's usual method of tax accounting). 

    Sale or Other Disposition.  In general, a U.S. Holder of Notes will 
recognize gain or loss upon the sale, exchange, redemption, or other taxable 
disposition of such Notes measured by the difference between (i) the amount 
of cash and the fair market value of property received and (ii) the U.S. 
Holder's adjusted tax basis in the Notes. A U.S. Holder's adjusted tax basis 
for determining gain or loss on the sale or other disposition of a Note will 
initially equal the cost of the Note to such U.S. Holder and will be 
increased by any accrued original issue discount (net of all amortized 
acquisition premium) and any market discount includable in such U.S. Holder's 
gross income and decreased by the amount of any cash payments received by 
such U.S. Holder regardless of whether such payments are denominated as 
principal or interest (other than payments of qualified stated interest) and 
amortizable bond premium, if any, deducted over the term of the Notes. 
Subject to the market discount rules discussed above, any such gain or loss 
will generally be long-term capital gain or loss, provided the Notes have 
been held for more than one year. Under the Taxpayer Relief Act of 1997, 
lower capital gains rates apply to the sale or exchange of Notes held by an 
individual taxpayer for more than 18 months. 

    Elections.  A U.S. Holder of Notes, subject to certain limitations, may 
elect to include all stated and unstated interest and discount on the Notes 
in gross income under the constant yield method. For this purpose, interest 
includes original issue discount, de minimis market discount and market 
discount, as adjusted by any amortizable bond premium or acquisition premium. 
Any such election, if made in respect of a market discount bond, will 
constitute an election to include market discount in income currently on all 
market discount bonds acquired by such U.S. Holder on or after the first day 
of the first taxable year to which the election applies. See "--Market 
Discount." U.S. Holders should consult with their tax advisors regarding any 
tax elections they intend to make with respect to any Notes. 

    Applicable High Yield Discount Rules.  Generally, under Section 163(e)(5) 
of the Code, original issue discount is not deductible until paid in cash or 
property (other than the Company debt or stock) with respect to any 
"applicable high yield discount obligations" ("AHYDOs") issued by a 
corporation. A Note will constitute an AHYDO since it (i) has a maturity date 
which is more than five years from the date of issue, (ii) has a yield to 
maturity which equals or exceeds the sum of five percentage points plus the 
"applicable federal rate" ("AFR") for the calendar month in which the 
obligation is issued and (iii) has "significant original issue discount" (as 
defined in Section 163(i)(2) of the Code). (The AFR for the month of October 
1997 is 6.24% for instruments with a weighted average maturity in excess of 
three years but not in excess of nine years providing semiannual 
compounding.) Since the Notes are AHYDOs, (i) the product of the total 
original issue discount under the Notes times the ratio of (a) the excess of 
the yield to maturity over the sum of the AFR plus six percentage points to 
(b) the yield to maturity will not be deductible by the Company and will be 
treated for some purposes as dividends to corporate holders of the Notes (to 
the extent that the Company has sufficient current or accumulated earnings 
and profits for federal income tax purposes that such non-deductible amounts 
would have been treated as dividends if they had been distributions with 
respect to the Company's stock), and (ii) any original issue discount for 
which the Company's deductions are not disallowed under clause (i) above will 
not be deductible by the Company until 

                                       64

actually paid. Amounts treated as dividends under clause (i) will be 
non-deductible by the Company, and may qualify for the dividends received 
deduction for corporate holders, but should be treated as original issue 
discount and must be included in income, as described above. The Company 
believes that it does not presently have any current or accumulated earnings 
and profits and it cannot predict whether it will have any earnings and 
profits for future years. As such, in any year in which the Company has no 
earnings and profits, the non-deductible portion in clause (i) relating to 
such year would not be eligible for the dividends received deduction in the 
case of corporate holders. 

    Information Reporting and Backup Withholding.  The "backup" withholding 
and information reporting requirements may apply to certain payments of 
principal and interest (including original issue discount) on a Note and to 
certain payments of proceeds on the sale or retirement of a Note. The 
Company, its agent, a broker, the Trustee or any paying agent, as the case 
may be, will be required to withhold tax from any payment that is subject to 
backup withholding at a rate of 31% if the U.S. Holder, among other things, 
(i) fails to furnish his or her social security number or other taxpayer 
identification number ("TIN") to the payor responsible for backup 
withholding, (ii) furnishes to such payor an incorrect TIN, (iii) fails to 
provide such payor with a certified statement, signed under penalties of 
perjury, that the TIN provided to the payor is correct and that the U.S. 
Holder is not subject to backup withholding or (iv) fails to report properly 
interest and dividends on his or her tax return. A holder who does not 
provide the Company or the applicable reporting entity with his or her 
correct TIN may be subject to penalties under the Code. Certain holders, 
including corporations, are not subject to backup withholding if their exempt 
status is properly established. 

    Backup withholding is not an additional tax. The amount of any backup 
withholding from a payment to a U.S. Holder will be allowed as a credit 
against such holder's United States federal income tax liability and may 
entitle such holder to a refund, provided that the required information is 
furnished to the Service. 

Tax Consequences to Non-U.S. Holders

    Portfolio Interest Exemption

    A Non-U.S. Holder will generally, under the portfolio interest exemption 
of the Code, not be subject to United States federal income taxes and/or 
United States federal withholding tax, on payments of principal, premium, if 
any, and interest (including original issue discount) on the Notes, provided 
that (in the case of interest, including original issue discount) (i) the 
Non-U.S. Holder does not actually or constructively own 10% or more of the 
total combined voting power of all classes of stock of the Company entitled 
to vote, (ii) the Non-U.S. Holder is not a controlled foreign corporation 
that is related to the Company through stock ownership, (iii) such original 
issue discount or interest is not effectively connected with a United States 
trade or business of the Non-U.S. Holder and (iv) either (a) the beneficial 
owner of the Notes certifies to the Company or its agent, under penalties of 
perjury, that it is a Non-U.S. Holder and provides a completed IRS Form W-8 
("Certificate of Foreign Status") or (b) a securities clearing organization, 
bank or other financial institution which holds customers' securities in the 
ordinary course of its trade or business (a "financial institution") and 
holds the Notes, certifies to the Company or its agent, under penalties of 
perjury, that it has received Form W-8 from the beneficial owner or that it 
has received from another financial institution a Form W-8 and furnishes the 
payor with a copy thereof. If any of the situations described in proviso (i), 
(ii) or (iv) of the preceding sentence do not exist, interest on the Notes 
when received is subject to United States withholding tax at the rate of 30% 
unless an income tax treaty between the United States and the country of 
which the Non-U.S. Holder is a tax resident provides for the elimination or 
reduction in the rate of United States federal withholding tax. Final 
Treasury Regulations (the "Regulations") issued October 6, 1997 will provide 
alternative methods for satisfying the certification requirement described in 
clause (iv)(a) and (b). The Regulations are proposed to be effective for 
payments made after December 31, 1998. 

    If a Non-U.S. Holder of a Note is engaged in a trade or business in the 
United States and interest (including original issue discount) on the Note is 
effectively connected with the conduct of such trade or business, such 
holder, although exempt from United States federal withholding tax by reason 
of the delivery of a properly completed Form 4224, will be subject to United 
States federal income tax on such interest (including original issue 
discount) and on any gain realized on the sale, exchange or other disposition 
of a Note in the same manner as if it were a U.S. Holder. In addition, if 
such Non-U.S. Holder is a foreign corporation, it may be subject to a branch 
profits tax equal to 30% of its effectively connected earnings and profits 
for that taxable year, unless it qualifies for a lower rate under an 
applicable income tax treaty. 

                                       65

<PAGE>

    Federal Estate Tax

    Notes owned or treated as owned by an individual who is neither a United 
States citizen nor a United States resident (as defined for United States 
federal estate tax purposes) at the time of death will be excluded from the 
individual's gross estate for the United States federal estate tax purposes 
and will not be subject to United States federal estate tax if the 
nonresident qualifies for the portfolio interest exemption (without regard to 
the certification requirements) discussed above. 

    Sale of Notes

    A Non-U.S. Holder generally will not be subject to United States federal 
income tax on any gain realized in connection with the sale, exchange or 
retirement of Notes, unless (i) (a) the gain is effectively connected with a 
trade or business carried on by the Non-U.S. Holder within the United States 
or, (b) if a tax treaty applies, the gain is attributable to the United 
States permanent establishment maintained by the Non-U.S. Holder, (ii) in the 
case of a Non-U.S. Holder who is an individual, such holder is present in the 
United States for 183 days or more in the taxable year of disposition and 
certain other conditions are satisfied, or (iii) the Non-U.S. Holder is 
subject to tax pursuant to provisions of the Code applicable to United States 
expatriates. 

    Information Reporting and Backup Withholding

    In general, there is no United States information reporting requirement 
or backup withholding tax on payments to Non-U.S. Holders who provide the 
appropriate certification described above regarding qualification for the 
portfolio interest exemption from United States federal income tax for 
payments of principal or interest (including original interest discount) on 
the Notes. 

    Payment by the Company of principal on the Notes or payment by a United 
States office of a broker of the proceeds of a sale of Notes is subject to 
both backup withholding and information reporting unless the beneficial owner 
provides a completed IRS Form W-8 which certifies under penalties of perjury 
that such owner is a Non-U.S. Holder who meets all the requirements for 
exemption from United States federal income tax on any gain from the sale, 
exchange or retirement of the Notes. 

    In general, backup withholding and information reporting will not apply 
to a payment of the gross proceeds of a sale of Notes effected at a foreign 
office of a broker. If, however, such broker is, for United States federal 
income tax purposes, a U.S. person, a controlled foreign corporation or a 
foreign person 50% or more of whose gross income for certain periods is 
derived from activities that are effectively connected with the conduct of a 
trade or business in the United States, such payments will not be subject to 
backup withholding, but will be subject to information reporting unless (i) 
such broker has documentary evidence in its records that the beneficial owner 
is a Non-U.S. Holder and certain other conditions are met, or (ii) the 
beneficial owner otherwise establishes an exemption, provided such broker 
does not have actual knowledge that the payee is a United States person. 
Non-U.S. Holders should consult their tax advisors regarding the application 
of these rules to their particular situations, the availability of an 
exemption therefrom and the procedure for obtaining such an exemption, if 
available. 

    Backup withholding is not an additional tax. Any amounts withheld under 
the backup withholding rules will be allowed as a credit against such 
holder's United States federal income tax liability and may entitle such 
holder to a refund, provided the required information is furnished to the 
Service. 

    THE FOREGOING SUMMARY DOES NOT DISCUSS ALL ASPECTS OF UNITED STATES 
FEDERAL INCOME TAXATION THAT MAY BE RELEVANT TO A PARTICULAR HOLDER OF NOTES 
IN LIGHT OF ITS PARTICULAR CIRCUMSTANCES AND INCOME TAX SITUATION. HOLDERS 
SHOULD CONSULT THEIR OWN TAX ADVISORS AS TO THE SPECIFIC TAX CONSEQUENCES TO 
THEM FROM THE PURCHASE, OWNERSHIP AND DISPOSITION OF THE NOTES, INCLUDING THE 
APPLICATION AND EFFECT OF STATE, LOCAL, FOREIGN AND OTHER TAX LAWS AND THE 
POSSIBLE EFFECTS OF CHANGES IN FEDERAL OR OTHER TAX LAWS.

             DESCRIPTION OF CERTAIN INDEBTEDNESS AND PREFERRED STOCK

Indebtedness

    Debt Placements

    March 1997 and August 1997

    In March 1997, the Company and WEC issued an aggregate of $300 million of 
notes in the March 1997 Debt Placement, consisting of (i) $100 million of the 
1997 Senior Notes, ranking pari passu with the 1995 Senior Notes, and (ii) 
$200 million of the WEC Notes. In order to provide additional future 
liquidity to the Company, the Company also obtained a $150 million facility 
("Facility") from affiliates of the Initial Purchasers. In August 1997, WEC 
II issued, pursuant to the Facility, $50.0 million of the WEC II Equipment 
Notes, thereby reducing the amount available under the Facility by $50.0 
million.  In October 1997, the Company utilized the remaining $100 million 
available under the Facility, issuing an aggregate of $100 million principal 
amount of the Notes in the October 1997 Debt Placement.

    The obligations of WEC and WEC II under the WEC Notes and the WEC II 
Notes are unconditionally guaranteed by the Company and are secured by a 
security interest in the equipment and other property purchased by WEC and 
WEC II, as the case may be, with the proceeds thereof.

    The WEC Notes bear interest at a rate of 121/2% per annum, payable on 
March 15 and September 15, commencing September 15, 1997.  The WEC Notes will 
mature on March 15, 2004 and are redeemable on or after March 15, 2002, at 
the option of the Company, in whole or in part, at the redemption prices set 
forth herein.  Additionally, in the event that by March 18, 1999, the Company 
has not applied $200.0 million to fund the acquisition costs of Designated 
Equipment (as defined), the Company is required to redeem the WEC Notes in an 
aggregate principal amount equal to such shortfall at a redemption price of 
112.50% of such principal amount, plus accrued interest, if any, to the date 
of redemption.

    The WEC II Notes bear interest at a rate of 121/2% per annum, payable on 
March 15 and September 15, commencing September 15, 1997.  The WEC II Notes 
mature on March 15, 2004 and are redeemable on or after March 15, 2002, at 
the option of The Company, in whole or in part, at certain prices.  
Additionally, in the event that by August 8, 1999, the Company has not 
applied $50.0 million to fund the acquisition costs of Designated Equipment, 
the Company is required to redeem August 1997 Equipment Notes in an aggregate 
principal amount equal to such shortfall at a redemption price of 112.50% of 
such principal amount, plus accrued interest, if any, to the date of 
redemption.

    The 1997 Senior Notes are unsecured, senior indebtedness of the Company, 
rank pari passu in right of payment with all existing and future senior 
indebtedness of the Company, and are senior in right of payment to all 
existing and future subordinated indebtedness of the Company.  Until October 
15, 2000, interest on the 1997 Senior Notes will accrue and compound 
semiannually, but will not be payable in cash. Interest on the Accumulated 
Amount (as defined in the 1997 Senior Notes Indenture) of the 1997 Senior 
Notes as of October 15, 2000 will be payable semiannually in cash on April 15 
and October 15 of each year commencing April 15, 2001. The Senior Notes 
mature on October 15, 2005 and are redeemable on or after October 15, 2000, 
at the option of the Company, in whole or in part, at certain prices.

    1995 Debt Placement

    In October 1995, the Company raised net proceeds of $214.5 million from 
the 1995 Debt Placement. The 1995 Notes will not accrue interest prior to 
October 15, 2000, nor pay cash interest prior to April 15, 2001; however, the 
principal value of such 1995 Notes have accreted since issuance and at 
maturity the 1995 Senior Notes and the Convertible Notes will have aggregate 
principal amounts of $294.2 million and $147.1 million, respectively. From 
and after October 15, 2000, the 1995 Notes will accrue interest at the rate 
of 14% per annum, payable semiannually in cash commencing April 15, 2001. The 
1995 Notes mature on October 15, 2005. 

    The Convertible Notes are convertible, at any time, at the option of the 
holder, into that number of shares of Common Stock derived by dividing the 
principal amount of the Convertible Notes being converted by $20.625. In 
addition, if the closing sale price of the Common Stock on the Nasdaq 
National Market during any twelve-month period 

                                       67
<PAGE>

from October 15, 1995 through October 15, 1999 (each a "Market Criteria 
Period") has exceeded the Market Criteria (as defined in the Indenture 
governing the Convertible Notes) and a registration statement with respect to 
Common Stock issuable upon conversion of the Convertible Notes ("Conversion 
Shares") is effective and available, all of the Convertible Notes 
automatically will be converted into Conversion Shares at the close of 
business on the last day of the Market Criteria Period. The Company has 
caused to be declared effective a registration statement registering the 
issuance or resale of the Conversion Shares. 

    Indentures

    The Indentures relating to the 1995 Notes and 1997 Notes contain certain 
covenants which, among other things, restrict the ability of the Company and 
certain of its subsidiaries to: incur additional indebtedness; create liens; 
engage in sale-leaseback transactions; pay dividends or make distributions in 
respect of their capital stock; make investments or certain other restricted 
payments; sell assets; issue or sell stock of such subsidiaries; enter into 
transactions with stockholders or affiliates; acquire assets or businesses 
not constituting "telecommunications assets" (as defined in the Indentures 
relating to the 1995 Notes); or consolidate, merge or sell all or 
substantially all of their assets. The covenants contained in the Indentures 
are subject to exceptions and the Company's new media and consumer products 
subsidiaries are not subject to many of the covenants contained therein, 
although the Company's ability to make additional investments in such 
subsidiaries is limited.

    Equipment Lease Financings and Credit Lines

    In September 1995, the Company's wholly owned subsidiary, WinStar 
Wireless, Inc. ("WinStar Wireless") entered into an equipment lease financing 
arrangement (the "Equipment Lease Financing") with ML Investors Services, 
Inc. ("ML"), pursuant to which ML has made available $7.0 million in 
equipment financing. Pursuant to a master lease agreement between WinStar 
Wireless and ML entered into in connection with the Equipment Lease 
Financing, WinStar Wireless has leased transceivers and related network 
equipment from ML or its assignee at the rate of 2.2753% of the equipment 
value per month (a return of approximately 13% per annum to the lessor), 
which lease payment obligations are non-cancelable for sixty months. After 
twelve months WinStar Wireless may purchase the equipment at scheduled rates 
which decline over the term of the lease and provide for a return of 
approximately 15% per annum to the lessor. WinStar Wireless' obligations 
under the lease are guaranteed by the Company. As additional consideration 
for providing the Equipment Lease Financing, the Company has issued to ML 
options to purchase 55,000 shares of Common Stock at an exercise price of 
$17.125 per share and options to purchase 15,000 shares of Common Stock at an 
exercise price of $18.0625 per share. 

    In November 1994, WinStar Gateway entered into a Loan and Security 
Agreement ("CIT Loan Agreement") with The CIT Group/Credit Finance, Inc. 
("CIT"), pursuant to which CIT agreed to make a $5.0 million revolving credit 
facility (the "CIT Credit Facility") available to WinStar Gateway until 
November 1998 as extended. Pursuant to the terms of the CIT Loan Agreement, 
borrowings are limited to 90% of the most eligible accounts receivable with 
eligibility of certain types of accounts receivable limited to 80% and 50% 
(less appropriate reserves as determined by CIT). In addition, WinStar 
Gateway is prohibited from paying dividends to the Company. The Company also 
is party to a keepwell agreement requiring the Company to make a monthly 
contribution to WinStar Gateway in an amount equal to the amount by which 
WinStar Gateway's net income (loss) before depreciation and amortization 
minus its capital expenditures is less than zero for a particular month. 
Borrowings bear interest at a rate of 1.75% in excess of the prime commercial 
lending rate of The Chase Manhattan Bank, N.A. subject to increase if WinStar 
Gateway's or the Company's net worth (as defined) drops below specified 
amounts, and are secured by a lien on all of WinStar Gateway's assets as well 
as a guarantee by the Company as to the first $2.2 million in borrowings. The 
CIT Loan Agreement also provides for certain underutilization fees and 
subordinates a $5 million revolving credit facility made by the Company to 
WinStar Gateway. As additional consideration for providing the CIT Credit 
Facility, the Company issued to CIT warrants to purchase 50,000 shares of 
Common Stock, which warrants have been exercised. 

    In August 1996, WinStar Global Products entered into an Amended and 
Restated Credit and Security Agreement (as amended, the "Credit Agreement") 
with IBJ Schroder Bank & Trust Company ("IBJ"), pursuant to which IBJ agreed 
to make a $10.0 million revolving credit facility (the "Revolving Credit 
Facility") and a $250,000 Letter of Credit facility (included within the 
Revolving Credit Facility) available to WinStar Global Products until 
August 8, 1999. Pursuant to the terms of the Credit Agreement, borrowings are 
limited to an amount equal to the sum of (a) 85% of eligible accounts 

                                       68

<PAGE>

receivable plus (b) the lesser of 50% of eligible inventory or $4,500,000 
plus (c) for the period commencing March 1 of each year through January 31 of 
the following year, $3.0 million (the "Overadvance"). Borrowings bear 
interest at a rate of 0.75% in excess of the base lending rate of IBJ and are 
secured by a lien on all of the assets of WinStar Global Products as well as 
a guaranty by the Company of any amounts borrowed as an Overadvance. The 
Credit Agreement also requires the payment of certain periodic fees by 
WinStar Global Products, contains certain affirmative and negative covenants 
including restrictions upon WinStar Global Products' ability to pay dividends 
or make other payments to the Company and subordinates a $3.1 million loan 
made by the Company to WinStar Global Products. The Credit Agreement amends 
and restates a loan agreement providing a $6.0 million credit facility from 
Century Business Credit Corporation ("Century") which was established in 1994 
and assigned (including all security interests and a $3.0 million guaranty 
given by the Company) by Century to IBJ. 

    In October 1997, WinStar Switch Acquisition Corp. ("WSAC"), a wholly 
owned subsidiary of the Company, consummated a purchase ("US ONE Asset 
Acquisition and Financing") of certain telecommunications assets (the 
"Assets") from US ONE Communications Corp. ("US ONE"), US ONE Communications 
Services Corp. and US ONE Communications of New York, Inc. (each individually 
a "Seller" and collectively, the "Sellers").  The Assets included 12 Lucent 
class 5 switching systems and other non-switch  assets.  The transaction 
required and received the approval of the United States Bankruptcy Court, 
District of Delaware ("Court"), because the Sellers are debtors in possession 
under Chapter 11 of the United States Bankruptcy Code of 1978, as amended.  
The aggregate purchase price paid for the Assets was approximately $81.1 
million, of which approximately $61.1  million was paid in cash at the 
closing and $20 million of which is payable  by the Company and WSAC in cash 
and/or shares of the common stock of the Company, at the Company's's 
discretion, on the effective date of Sellers' confirmed plan of 
reorganization.  In order to finance the cash portion of the  purchase price 
and to pay certain expenses, on the Closing Date, WSAC borrowed $62.25 
million (the "Loan") from certain institutions (together, the "Lenders").  
The Loan maturity date is April 22, 1998; provided, however, that WSAC must 
prepay the Loan (or portions thereof) with the proceeds of any sale by it of 
the purchased Assets and with proceeds obtained from certain financings. The 
Loan is guaranteed by the Company and is secured by the telecommunications 
switches and related equipment, inventory and software included in the Assets.

    The Company's subsidiaries have entered into, and will continue 
to seek, financing arrangements with respect to equipment, including 
telecommunications switches, 38 GHz radios and other related equipment. The 
Company's subsidiary, WinStar Telecommunications, Inc., consummated a $3.1 
million sale/leaseback of its New York City switch in December 1996 and a 
$3.8 million sale/leaseback of its Los Angeles switch in April 1997 and 
borrowed approximately $3.3 million from a third party lender in connection 
with its purchase of its Chicago switch in March 1997. In May 1997, the 
Company's subsidiary, WinStar Wireless, Inc., consummated a $10 million 
sale/leaseback of 38 GHZ radios. The Company may enter into additional 
financing arrangements for switches, radios and other equipment on similar 
terms in the future. 

Preferred Stock

    Series A Preferred Stock

    On February 6, 1997, the Company and its wholly owned subsidiary, WinStar 
Credit Corp. ("WCC"), entered into a Securities Purchase Agreement with 
certain purchasers, pursuant to which the Company and WCC agreed to sell to 
such purchasers an aggregate of 4,000,000 shares of the Company's Series A 
Preferred Stock ("Series A Preferred Stock") and warrants to purchase 
1,600,000 shares of the Company's Common Stock (the "Warrants") for an 
aggregate purchase price of $100.0 million. The Preferred Stock Placement was 
consummated on February 11, 1997. The Preferred Stock Placement was conducted 
through Credit Suisse First Boston Corporation, which acted as placement 
agent and received customary fees for acting in such capacity. The principal 
purpose of the Preferred Stock Placement was to raise proceeds to fund the 
expansion of the Company's telecommunications and other operations. 

    Each share of Series A Preferred Stock has a stated value of $25 ("Stated 
Value") and entitles the holder thereof to receive from the Company dividends 
at a rate per annum equal to 6% of the Stated Value. Dividends accrue and are 
cumulative from the date of issuance and are payable in arrears quarterly as 
of March 31, June 30, September 30 and December 31 of each year. The Company 
may, at its election, pay such dividends in cash or through the issuance of 
additional shares of Series A Preferred Stock. 

                                       69

<PAGE>

    The shares of Series A Preferred Stock are convertible into shares of 
Common Stock by dividing the aggregate Stated Value of the Series A Preferred 
Stock being converted by the Conversion Price (as defined below).  Subject to 
certain adjustments, the "Conversion Price" will be: (i) with respect to any 
conversion of Series A Preferred Stock occurring prior to February 11, 1998, 
the lesser of (x) $25 and (y) the average of the closing bid prices for the 
Common Stock for the 20 consecutive trading days immediately preceding the 
date of conversion and (ii) with respect to any conversion of the Series A 
Preferred Stock occurring on or after February 11, 1998, the lesser of (x) 
$25 and (y) the average of the closing bid prices for the 20 consecutive 
trading days immediately preceding February 11, 1998. Notwithstanding the 
foregoing, if a holder of Series A Preferred Stock requests conversion at a 
time when the Conversion Price is less than $15, the Company may (subject to 
certain notice requirements), in lieu of converting such Series A Preferred 
Stock into shares of Common Stock, pay such holder in cash an amount equal to 
110% of the Liquidation Preference (as defined below) for each share of 
Series A Preferred Stock requested to be converted. On February 11, 2002, any 
Series A Preferred Stock still outstanding shall be automatically converted 
into shares of Common Stock, unless the Company elects to pay cash therefor 
in an amount equal to the Stated Value plus all accrued and unpaid dividends 
thereon (the "Liquidation Preference"). Unless paid for in cash, such 
conversion will be effected by delivery of shares of Common Stock having a 
value, based upon the closing bid prices for the Common Stock for the 20 
consecutive trading days ending one trading day prior to such conversion 
date, equal to the Liquidation Preference. 

    The Warrants entitle the holders thereof to purchase an aggregate of 
1,600,000 shares of Common Stock for $25 per share at any time commencing 
February 11, 1998 and ending February 11, 2002. The Company may accelerate 
the expiration date at any time after February 11, 2000 if Common Stock 
trades at $40 or more for a period of 20 consecutive days. 

    The Company and the purchasers of the Series A Preferred Stock also 
entered into a Registration Rights Agreement, dated February 6, 1997 (the 
"Preferred Stock Registration Rights Agreement"), pursuant to which the 
Company currently maintains an effective registration statement under the 
Securities Act, registering (i) the resale of the Series A Preferred Stock 
and Warrants and (ii) the issuance by the Company of the shares of Common 
Stock issuable upon exercise of the Series A Preferred Stock and Warrants. 

    Rights to Purchase Series B Preferred Stock

    The following is a summary of the Rights Agreement dated as of July 2, 
1997 (the "Rights Plan"), between the Company and Continental Stock Transfer 
& Trust Company, as Rights Agent, which was adopted by the Board of Directors 
of the Company on July 2, 1997. This summary of the Rights Plan does not 
purport to be complete and is qualified in its entirety by reference to the 
provisions of the Rights Plan. 

    Under the Rights Plan, holders of Common Stock of the Company received, 
as a dividend, preferred stock purchase rights (the "Rights") at the rate of 
one Right for each share of Common Stock held as of the close of business on 
July 14, 1997. One Right will also attach to each share of Common Stock 
issued thereafter. Currently the Rights are not separate from the Common 
Stock and are not exercisable, and the Rights will only separate from the 
Common Stock and become exercisable if a person or group acquires 10% or more 
of the Company's outstanding Common Stock (an "Acquiring Person") or launches 
a tender or exchange offer that would result in ownership of 10% or more the 
Company's outstanding Common Stock. Each Right that is not owned by an 
Acquiring Person entitles the holder of the Right to buy one one-thousandth 
of one share (a "Unit") of Series B Preferred Stock which will be issued by 
the Company. If any person becomes an Acquiring Person, or if an Acquiring 
Person engages in certain transactions involving conflicts of interest or in 
a business combination in which the Company's Common Stock remains 
outstanding, then the Rights Plan provides that each Right, other than any 
Right held by the Acquiring Person, entitles the holder to purchase, for $70, 
Units with a market value of $140. However, if the Company is involved in a 
business combination in which the Company itself is not the survivor, or if 
the Company sells 50% or more of its assets or earning power to another 
person, then the Rights Plan provides that each Right entitled the holder to 
purchase, for $70, shares of the common stock of the Acquiring Person's 
ultimate parent having a market value of $140. 

    At any time until ten days following the date on which a person acquires 
10% or more of the Company's Common Stock, the Company may redeem all (but 
not less than all) of the Rights for $0.0001 per Right. The Rights expire in

                              PLAN OF DISTRIBUTION

    Each broker-dealer that receives New Notes for its own account pursuant 
to this 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 180 days 
after the Expiration Date (or such longer period as required by the terms of 
the Registration Rights Agreement), it will make this Prospectus, as amended 
or supplemented, available to any broker-dealer for use in connection with 
any such resale.  In addition, until _______ __, 1998 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 an 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 or the purchasers of any such New 
Notes.  Any broker-dealer that resells New Notes that were received by it for 
is own account pursuant to an 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 commission 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 180 days after the Expiration Date (or such longer period 
as required by the terms of the Registration Agreement), 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 to pay all 
expenses incidental to the Exchange Offers (including the reasonable expenses 
of one counsel for the Holders of the Notes) other than commissions or 
concessions of any brokers or dealers and will indemnify the Holders of the 
Notes (including any broker-dealers) against certain liabilities, including 
liabilities under the Securities Act.

    The Company has agreed to pay all expenses incident to the Exchange Offer 
other than commissions or concessions of any brokers or dealers and transfer 
taxes and costs incurred by a holder in transmitting its Old Notes to the 
Exchange Agent and will indemnify the holders of the Old Notes (including any 
broker-dealers) against certain liabilities, including liabilities under the 
Securities Act.

Financing (the "Financing Transactions" and, together with the Milliwave 
Acquisition, the "Transactions") as if they occurred as of the beginning of 
the year ended December 31, 1996. The revenues and results of operations 
included in the following unaudited pro forma condensed consolidated 
statements of operations are not indicative of anticipated results of 
operations for periods subsequent to the Transactions nor are they considered

beginning of the year ended December 31, 1996.
 
    The following unaudited pro forma condensed consolidated statement of 
operations for the nine months ended September 30, 1997 gives effect to the 
Financing Transactions as if they occurred as of the beginning of the nine 
months ended September 30, 1997. The revenues and results of operations 
included in the following unaudited pro forma condensed consolidated 
statement of operations are not indicative of anticipated results of

                        INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 20.  Indemnification of Directors and Officers

    The Company's Certificate of Incorporation provides that all directors,
officers, employees and agents of the Registrant shall be entitled to be
indemnified by the Company to the fullest extent permitted by law.  

    Section 145 of the Delaware General Corporation Law concerning
indemnification of officers, directors, employees and agents is set forth below.

    "Section 145.  Indemnification of officers, directors, employees and
agents; insurance.

         (a)  A corporation shall have power to indemnify any person who was 
or is a party or is threatened to be made a party to any threatened, pending 
or completed action, suit or proceeding, whether civil, criminal, 
administrative or investigative (other than an action by or in the right of 
the corporation) by reason of the fact that the person is or was a director, 
officer, employee or agent of the corporation, or is or was serving at the 
request of the corporation as a director, officer, employee or agent of 
another corporation, partnership, joint venture, trust or other enterprise, 
against expenses (including attorneys' fees), judgments, fines and amounts 
paid in settlement actually and reasonably incurred by the person in 
connection with such action, suit or proceeding if the person acted in good 
faith and in a manner the person reasonably believed to be in or not opposed 
to the best interests of the corporation, and, with respect to any criminal 
action or proceeding, had no reasonable cause to believe the person's conduct 
was unlawful.  The termination of any action, suit or proceeding by judgment, 
order, settlement, conviction, or upon a plea of nolo contendere or its 
equivalent, shall not, of itself, create a presumption that the person did 
not act in good faith and in a manner which the person reasonably believed to 
be in or not opposed to the best interests of the corporation, and, with 
respect to any criminal action or proceeding, had reasonable cause to believe 
that the person's conduct was unlawful.

    (b)  A corporation shall have power to indemnify any person who was or is 
a party or is threatened to be made a party to any threatened, pending or 
completed action or suit by or in the right of the corporation to procure a 
judgment in its favor by reason of the fact that the person is or was a 
director, officer, employee or agent of the corporation, or is or was serving 
at the request of the corporation as a director, officer, employee or agent 
of another corporation, partnership, joint venture, trust or other enterprise 
against expenses (including attorneys' fees) actually and reasonably incurred 
by the person in connection with the defense or settlement of such action or 
suit if the person acted in good faith and in a manner the person reasonably 
believed to be in or not opposed to the best interests of the corporation and 
except that no indemnification shall be made in respect of any claim, issue 
or matter as to which such person shall have been adjudged to be liable to 
the corporation unless and only to the extent that the Court of Chancery or 
the court in which such action or suit was brought shall determine upon 
application that, despite the adjudication of liability but in view of all 
the circumstances of the case, such person is fairly and reasonably entitled 
to indemnity for such expenses which the Court of Chancery or such other 
court shall deem proper.

    (c)  To the extent that a director, officer, employee or agent of a 
corporation has been successful on the merits or otherwise in defense of any 
action, suit or proceeding referred to in subsections (a) and (b) of this 
section, or in defense of any claim, issue or matter therein, he shall be 
indemnified against expenses (including attorneys' fees) actually and 
reasonably incurred by him in connection therewith.

    (d)  Any indemnification under sections (a) and (b) of this section 
(unless ordered by a court) shall be made by the corporation only as 
authorized in the specific case upon a determination that indemnification of 
the director, officer, employee or agent is proper in the circumstances 
because the person has met the applicable standard of conduct set forth in 
subsections (a) and (b) of this section.  Such determination shall be made 
(1) by a majority vote of the directors who are not parties to such action, 
suit or proceeding, even though less than a quorum, or (2) if there are no 
such directors, or if such directors so direct, by independent legal counsel 
in a written opinion, or (3) by the stockholders.                             

                                       II-1
<PAGE>
 
    (e)  Expenses (including attorneys' fees) incurred by an officer or 
director in defending any civil, criminal, administrative or investigative 
action, suit or proceeding may be paid by the corporation in advance of the 
final disposition of such action, suit or proceeding upon receipt of an 
undertaking by or on behalf of such director or officer to repay such amount 
if it shall ultimately be determined that he is not entitled to be 
indemnified by the corporation as authorized in this section.  Such expenses 
(including attorney's fees) incurred by other employees and agents may be so 
paid upon such terms and conditions, if any, as the board of directors deems 
appropriate.

    (f)  The indemnification and advancement of expenses provided by, or 
granted pursuant to, the other subsections of this section shall not be 
deemed exclusive of any other rights to which those seeking indemnification 
or advancement of expenses may be entitled under any bylaw, agreement, vote 
of stockholders or disinterested directors or otherwise, both as to action in 
his official capacity and as to action in another capacity while holding such 
office.

    (g)  A corporation shall have power to purchase and maintain insurance on 
behalf of any person who is or was a director, officer, employee or agent of 
the corporation, or is or was serving at the request of the corporation as a 
director, officer, employee or agent of another corporation, partnership, 
joint venture, trust or other enterprise against any liability asserted 
against him and incurred by him in any such capacity, or arising out of his 
status as such, whether or not the corporation would have the power to 
indemnify him against such liability under this section.

    (h)  For purposes of this section, references to "the corporation" shall 
include, in addition to the resulting corporation, any constituent 
corporation (including any constituent of a constituent) absorbed in a 
consolidation or merger which, if its separate existence had continued, would 
have had power and authority to indemnify its directors, officers, and 
employees or agents, so that any person who is or was a director, officer, 
employee or agent of such constituent corporation, or is or was serving at 
the request of such constituent corporation as a director, officer, employee 
or agent of another corporation, partnership, joint venture, trust or other 
enterprise, shall stand in the same position under this section with respect 
to the resulting or surviving corporation as he would have with respect to 
such constituent corporation if its separate existence had continued.

    (i)  For purposes of this section, references to "other enterprises" 
shall include employee benefit plans; references to "fines" shall include any 
excise taxes assessed on a person with respect to any employee benefit plan; 
and references to "serving at the request of the corporation" shall include 
any service as a director, officer, employee or agent of the corporation 
which imposes duties on, or involves services by, such director, officer, 
employee or agent with respect to an employee benefit plan, its participants 
or beneficiaries; and a person who acted in good faith and in a manner he 
reasonably believed to be in the interest of the participants and 
beneficiaries of an employee benefit plan shall be deemed to have acted in a 
manner "not opposed to the best interests of the corporation" as referred to 
in this section.

    (j)  The indemnification and advancement of expenses provided by, or 
granted pursuant to, this section shall, unless otherwise provided when 
authorized or ratified, continue as to a person who has ceased to be a 
director, officer, employee or agent and shall inure to the benefit of the 
heirs, executors and administrators of such a person."

    Insofar as indemnification for liabilities arising under the Securities 
Act of 1933 may be permitted to directors, officers, and controlling persons 
of the Company pursuant to the foregoing provisions, or otherwise, the 
Company has been advised that in the opinion of the Securities and Exchange 
Commission such indemnification is against public policy as expressed in the 
Securities Act of 1933 and is, therefore, unenforceable.  In the event that a 
claim for indemnification against such liabilities (other than the payment by 
the Company of expenses incurred or paid by a director, officer or 
controlling person of the Company in a 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 Company will, unless in 
the opinion of its counsel the matter has been settled by controlling 
precedent, submit to a court of appropriate jurisdiction the question whether 
such indemnification by it is against public policy as expressed in the 
Securities Act of 1933 and will be governed by the final adjudication of such 
issue.

ITEM 22.  Undertakings.

    (a)  The undersigned registrant hereby undertakes:

         (1)  To file, during any period in which offers or sales are being
made, a post-effective amendment to this registration statement:

              (i)  To include any prospectus required by Section 10(a)(3) of
    the Securities Act of 1933;

              (ii) To reflect in the prospectus any facts or events arising 
after the effective date of the registration statement (or the most recent 
post-effective amendment thereof) which, individually or in the aggregate, 
represent a fundamental change in the information set forth in the 
registration statement.  Notwithstanding the foregoing, any increase or 
decrease in volume of securities offered (if the total dollar value of 
securities offered would not exceed that which was registered) and any 
deviation from the low or high and of the estimated maximum offering range 
may be reflected in the form of prospectus filed with the Commission pursuant 
to Rule 424(b) if, in the aggregate, the changes in volume and price 
represent no more than 20 percent change in the maximum aggregate offering 
price set forth in the "Calculation of Registration Fee" table in the 
effective registration statement;

              (iii) To include any material information with respect to the 
plan of distribution not previously disclosed in the registration statement 
or any material change to such information in the registration statement;

provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if 
the registration statement is on Form S-3, Form S-8 or Form F-3, and the 
information required to be included in a post-effective amendment by those 
paragraphs is contained in periodic reports filed with or furnished to the 
Commission by the registrant pursuant to Section 13 or 15(d) of the 
Securities Exchange Act of 1934 that are incorporated by reference in the 
registration statement.    

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

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

    (b)  The undersigned registrant hereby undertakes that, for purposes of 
determining any liability under the Securities Act of 1933, each filing of 
the registrant's annual report pursuant to Section 13(a) or 15(d) of the 
Securities Exchange Act of 1934 (and, where applicable, each filing of an 
employee benefit plan's annual report pursuant to Section 15(d) of the 
Securities Exchange Act of 1934) that is incorporated by reference in the 
registration statement shall be deemed to be a new registration statement 
relating to the securities offered therein, and the offering of such 
securities at that time shall be deemed to be the initial bona fide offering 
thereof.

    (c)  The undersigned registrant hereby undertakes to respond to requests 
for information that is incorporated by reference into the prospectus 
pursuant to Item 4, 10(b), 11 or 13 of this form, within one business day of 
receipt of such request, and to send the incorporated documents by first 
class mail or other equally prompt means.  This includes information 
contained in documents filed subsequent to the effective date of the 
registration statement through the date of responding to the request.

    (d)  The undersigned registrant hereby undertakes to supply by means of a 
post-effective amendment all information concerning a transaction, and the 
company being acquired involved therein, that was not the subject of and 
included in the registration statement when it became effective.

    Until March 1, 2002, interest on the Notes will accrue at a rate of 15% per
annum and be compounded semiannually on each SemiAnnual Interest Accrual Date,
but (except as provided below) will not be payable in cash.  From and after
March 1, 2002, interest on the Accumulated Amount of each Note will be payable
semiannually (to the holders of record of the Notes at the close of business on
the February 15 or August 15 immediately preceding the relevant Interest Payment
Date) on each Interest Payment Date, commencing September 1, 2002.

    "Accumulated Amount" means, as of any date (the "Specified Date"), the
amount provided below for each $1,000 principal amount of Notes.

          (i)   If the Specified Date occurs on one of the following dates
    (each, a "SemiAnnual Interest Accrual Date"), the Accumulated Amount of 
    this Note will equal the amount set forth below for such Note for such
    SemiAnnual Interest Accrual Date:

             SemiAnnual Interest Accrual Date            Accumulated Amount
             --------------------------------            ------------------

             March 1, 1998...........................   $1060.000
             September 1, 1998.......................    1139.500
             March 1, 1999...........................    1224.963
             September 1, 1999.......................    1316.835
             March 1, 2000...........................    1415.597
             September 1, 2000.......................    1521.767
             March 1, 2001...........................    1635.900
             September 1, 2001.......................    1758.592
             March 1, 2002...........................    1890.486

          (ii)   if the Specified Date occurs before the first SemiAnnual 
    Interest Accrual Date, the Accumulated Amount will equal the sum of (A) 
    $1,000 and (B) an amount equal to the product of (1) the Accumulated 
    Amount for the first SemiAnnual Interest Accrual Date less $1,000 
    multiplied by (2) a fraction, the numerator of which is the number of 
    days elapsed from the Issue Date to the Specified Date, using a 360-day 


<PAGE>

                                    EA-4

    year of twelve 30-day months, and the denominator of which is the number 
    of days from the Issue Date to the first SemiAnnual Interest Accrual 
    Date, using a 360-day year of twelve 30-day months;

          (iii)   if the Specified Date occurs between two SemiAnnual 
    Interest Accrual Dates, the Accumulated Amount will equal the sum of (A) 
    the Accumulated Amount for the SemiAnnual Interest Accrual Date 
    immediately preceding such Specified Date and (B) an amount equal to the 
    product of (1) the Accumulated Amount for the immediately following 
    SemiAnnual Interest Accrual Date less the Accumulated Amount for the 
    immediately preceding SemiAnnual Interest Accrual Date multiplied by (2) 
    a fraction, the numerator of which is the number of days elapsed from the 
    immediately preceding SemiAnnual Interest Accrual Date to the Specified 
    Date, using a 360-day year or twelve 30-day months, and the denominator 
    of which is 180; or 

          (iv)   if the Specified Date occurs after the last SemiAnnual
    Interest Accrual Date, the Accumulated Amount of this Note will equal 
    $1890.486.

    Notwithstanding anything to the contrary above, (i) if a Registration
Default (as defined in the Registration Rights Agreement) occurs, additional
interest will accrue on this Note from and including the date on which any such
Registration Default shall occur to but excluding the earlier of (x) the date on
which all Registration Defaults have been cured and (y) the date on which all
Notes become freely transferable by Holders other than Affiliates of the Company
without further registration under the Securities Act.  Such additional interest
will be payable in cash semiannually in arrears, at a rate per annum equal to
 .50% of the Accumulated Amount of the Notes on the relevant additional interest
payment date.  Such additional interest will be payable on each SemiAnnual
Interest Accrual Date or Interest Payment Date, as the case may be, commencing
with the first SemiAnnual Interest Accrual Date following the applicable
Registration Default.  Payments of additional interest on the Notes will be made
to the Holders of Notes on the Regular Record Date (or, if there is no Regular
Record Date, the date 15 days prior to such SemiAnnual Interest Accrual Date)
immediately preceding such SemiAnnual Interest Accrual Date or Interest Payment
Date.

    The Company shall pay interest on overdue principal and premium, if any,
and (to the extent lawful) interest on overdue installments of interest.

2.   Method of Payment.

    The Company will pay principal as provided above and interest (except
defaulted interest) on the Accumulated Amount of the Notes as provided above on
each March 1 and September 1, commencing September 1, 2002, to the persons who
are Holders (as reflected in the Security Register) at the close of business on
the  February 15 or August 15 immediately preceding the relevant Interest
Payment Date, in each case, even if the Note is cancelled on registration of
transfer or registration of exchange after such record date; provided, however,
that, with respect to the payment of principal, the Company will not make
payment to the Holder unless this Note is surrendered to a Paying Agent.


<PAGE>

                                   EA-5

    The Company will pay principal and interest in money of the United States
that at the time of payment is legal tender for payment of public and private
debts.  Payments in respect of the Notes represented by a global Note (including
principal, premium and interest) will be made by wire transfer of immediately
available funds to the accounts specified by The Depository Trust Company.  The
Company will make all payments in respect of a certificated Note (including
principal, premium and interest) by mailing a check to the registered address of
each Holder thereof; provided, however, that payments on a certificated Note
will be made by wire transfer to a U.S. dollar account maintained by the payee
with a bank in the United States if such Holder elects payment by wire transfer
by giving written notice to the Trustee or the Paying Agent to such effect
designating such account no later than 30 days immediately preceding the
relevant due date for payment (or such other date as the trustee may accept in
its discretion).

3.  Paying Agent and Registrar.

    Initially, United States Trust Company of New York (the "Trustee") will act
as authenticating agent, Paying Agent and Registrar.  The Company may change any
authenticating agent, Paying Agent or Registrar without notice.  The Company,
any Subsidiary or any Affiliate of any of them may act as Paying Agent,
Registrar or co-Registrar.

4.  Indenture.

    The Company issued the Notes under an Indenture dated as of October 1, 1997
(the "Indenture"), between the Company and the Trustee.  Capitalized terms
herein are used as defined in the Indenture unless otherwise indicated.  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.  The Notes are subject to
all such terms, and Holders are referred to the Indenture and the Trust
Indenture Act for a statement of all such terms.  To the extent permitted by
applicable law, in the event of any inconsistency between the terms of this Note
and the terms of the Indenture, the terms of the Indenture shall control.

    The Indenture limits the original aggregate principal amount of the Notes
to $100,000,000 (subject to Section 2.07 of the Indenture).

5.  Redemption.

    The Notes will not be redeemable prior to March 1, 2002.  Thereafter, the
Notes will be redeemable, at the Company's option, in whole at any time or in
part from time to time upon not less than 30 nor more than 60 days' prior notice
mailed by first-class mail to each Holders' last address as it appears in the
Security Register, at the following Redemption Prices (expressed as a percentage
of the Accumulated Amount of the Notes), plus accrued and unpaid interest, if
any, on such Accumulated Amount to the Redemption Date (subject to the right of
Holders of record on the relevant Regular Record Date that is on or prior to the
Redemption Date to receive interest due on the relevant Interest Payment Date),


<PAGE>

                                   EA-6

if redeemed during the 12-month period commencing March 1 of the years set forth
below:

         Year                       Redemption Price
         -----                      -----------------

         2002.....................     107.500%
         2003.....................     103.750
         2004 and thereafter......     100.000

6.  Notice of Redemption.

    Notice of any optional redemption will be mailed by the Company at least 30
days but not more than 60 days before a Redemption Date to each Holder of Notes
to be redeemed at his last address as it appears in the Security Register. 
Notes in original denominations larger than $1,000 may be redeemed in part;
provided, however, that Notes will only be issued in denominations of $1,000
principal amount or integral multiples thereof.  On and after the Redemption
Date, interest ceases to accrue on Notes (or portions of Notes) called for
redemption, unless the Company defaults in the payment of the Redemption Price.

7.   Repurchase upon Change in Control.

    Upon the occurrence of a Change of Control, each Holder shall have the
right to require the repurchase of its Notes by the Company in cash pursuant to
the offer described in the Indenture at a purchase price equal to 101% of the
Accumulated Amount of such Notes on such date of purchase, plus accrued and
unpaid interest, if any, on such Accumulated Amount to the date of purchase (the
"Change of Control Payment").

    A notice of such Change of Control will be mailed within 30 days after any
Change of Control occurs to each Holder at his last address as it appears in the
Security Register.  Notes in original denominations larger than $1,000 may be
sold to the Company in part; provided, however, that Notes will only be issued
in denominations of $1,000 principal amount at maturity or integral multiples
thereof.  On and after the Change of Control Payment Date, interest ceases to
accrue on Notes or portions of Notes surrendered for purchase by the Company,
unless the Company defaults in the payment of the Change of Control Payment.

8.   Denominations; Transfer; Exchange.

    The Notes are in registered form without coupons in denominations of $1,000
of principal amount and integral multiples thereof.  A Holder may register the
transfer or exchange of Notes in accordance with the Indenture.  The Registrar
may require a Holder, among other things, to furnish appropriate endorsements
and transfer documents and to pay any taxes and fees required by law or
permitted by the Indenture.  The Registrar need not register the transfer or
exchange of any Notes selected for redemption.  Also, it need not register the
transfer or exchange of any Notes for a period of 15 days before a selection of
Notes to be redeemed is made.

<PAGE>

                                   EA-7

9.  Persons Deemed Owners.

    A Holder shall be treated as the owner of a Note for all purposes.

10. Unclaimed Money.

    If money for the payment of principal, premium, if any, or interest remains
unclaimed for two years, the Trustee and the Paying Agent will pay the money
back to the Company at its request.  After that, Holders entitled to the money
must look to the Company for payment, unless an applicable law designates
another Person, and all liability of the Trustee and such Paying Agent with
respect to such money shall cease.

11. Discharge Prior to Redemption or Maturity.

    Subject to certain conditions, the Company at any time may terminate some
or all of its obligations under the Notes and the Indenture if the Company
deposits with the Trustee money or U.S. Government Obligations for the payment
of principal and interest on the Notes to redemption or maturity, as the case
may be.

12. Amendment; Supplement; Waiver.

    Subject to certain exceptions, the Indenture or the Notes may be amended or
supplemented with the consent of the Holders of at least a majority in principal
amount of the Notes then outstanding, and any existing default or compliance
with any provision may be waived with the consent of the Holders of at least a
majority in principal amount of the Notes then outstanding.  Without notice to
or the consent of any Holder, the parties thereto may amend or supplement the
Indenture or the Notes to, among other things, cure any ambiguity, defect or
inconsistency and make any change that, in the opinion of the Board of Directors
of the Company, does not materially and adversely affect the rights of any
Holder.

13.  Restrictive Covenants.

    The Indenture imposes certain limitations on the ability of the Company and
its Restricted Subsidiaries, among other things, to incur additional
indebtedness; pay dividends or make distributions in respect of their capital
stock; make investments or make certain other restricted payments; sell assets;
issue or sell stock of Restricted Subsidiaries; enter into transactions with
stockholders or affiliates; or, with respect to the Company, consolidate, merge
or sell all or substantially all of its assets.  Within 90 days after the end of
the last fiscal quarter of each year, the Company must report to the Trustee on
compliance with such limitations.

                                  EA-8

14. Successor Persons.

    Generally, when a successor person or other entity assumes all the
obligations of its predecessor under the Notes and the Indenture, the
predecessor person will be released from those obligations.

15. Defaults and Remedies.

    The following events constitute "Events of Default" under the Indenture:
(a) default in the payment of principal of (or premium, if any, on) any Note
when the same becomes due and payable, upon acceleration, redemption or
otherwise whether or not such payment is prohibited by the subordination
provisions of the Indenture; (b) default in the payment of interest on any Note
when the same becomes due and payable, and such default continues for a period
of 30 days whether or not such payment is prohibited by the subordination
provisions of the Indenture; (c) the Company defaults in the performance of or
breaches any other covenant or agreement of the Company in the Indenture or
under the Notes and such default or breach continues for a period of 30
consecutive days after written notice by the Trustee or the Holders of 25% or
more in aggregate principal amount of the Notes; (d) there occurs with respect
to any issue or issues of Indebtedness of the Company or any Significant
Subsidiary having an outstanding principal amount of $25,000,000 or more in the
aggregate for all such issues of all such Persons, whether such Indebtedness now
exists or shall hereafter be created, (i) an event of default that has caused
the holder thereof to declare such Indebtedness to be due and payable prior to
its Stated Maturity and such Indebtedness has not been discharged in full or
such acceleration has not been rescinded or annulled within 30 days of such
acceleration and/or (ii) the failure to make a principal payment at the final
(but not any interim) fixed maturity and such defaulted payment shall not have
been made, waived or extended within 30 days of such payment default; (e) any
final judgment or order (not covered by insurance) for the payment of money in
excess of $25,000,000 in the aggregate for all such final judgments or orders
against all such Persons (treating any deductibles, self-insurance or retention
as not so covered) shall be rendered against the Company or any Significant
Subsidiary and shall not be paid or discharged, and there shall be any period of
60 consecutive days following entry of the final judgment or order that causes
the aggregate amount for all such final judgments or orders outstanding and not
paid or discharged against all such Persons to exceed $25,000,000 during which a
stay of enforcement of such final judgment or order, by reason of a pending
appeal or otherwise, shall not be in effect; (f) a court having jurisdiction in
the premises enters a decree or order for (i) relief in respect of the Company
or any Significant Subsidiary in an involuntary case under any applicable
bankruptcy, insolvency or other similar law now or hereafter in effect,
(ii) appointment of a receiver, liquidator, assignee, custodian, trustee,
sequestrator or similar official of the Company or any Significant Subsidiary or
for all or substantially all of the property and assets of the Company or any
Significant Subsidiary or (iii) the winding up or liquidation of the affairs of
the Company or any Significant Subsidiary and, in each case, such decree or
order shall remain unstayed and in effect for a period of 60 consecutive days;
or (g) the Company or any Significant Subsidiary (i) commences a voluntary case
under any applicable bankruptcy, insolvency or other similar law now or
hereafter in effect, or consents to the entry of an order for relief in an
involuntary case under any such law, (ii) consents to the appointment of or


<PAGE>

                                     EA-9

taking possession by a receiver, liquidator, assignee, custodian, trustee,
sequestrator or similar official of the Company or any Significant Subsidiary or
for all or substantially all of the property and assets of the Company or any
Significant Subsidiary or (iii) effects any general assignment for the benefit
of creditors.

    If an Event of Default (other than an Event of Default specified in clause
(f) or (g) above that occurs with respect to the Company) occurs and is
continuing under the Indenture, the Trustee or the Holders of at least 25% in
aggregate principal amount of the Notes, then outstanding, by written notice to
the Company (and to the Trustee if such notice is given by the Holders), may,
and the Trustee at the request of such Holders shall, declare the principal of,
premium, if any, and accrued interest, if any, on the Notes to be immediately
due and payable.  If a bankruptcy or insolvency default with respect to the
Company or any Restricted Subsidiary occurs and is continuing, the principal
amount of the Notes automatically becomes due and payable.  Holders may not
enforce the Indenture or the Notes except as provided in the Indenture.  The
Trustee may require indemnity satisfactory to it before it enforces the
Indenture or the Notes.  Subject to certain limitations, Holders of at least a
majority in principal amount of the Notes then outstanding may direct the
Trustee in its exercise of any trust or power.

16. Subordination.

    The payment of the Notes is, to the extent set forth in the Indenture,
subordinated in right of payment in full, in cash or cash equivalents, of all
Senior Indebtedness of the Company.  To the extent provided in the Indenture,
Senior Indebtedness of the Company must be paid before the Notes may be paid. 
The Company agrees, and each Holder by accepting a Note agrees, to the
subordination provisions contained in the Indenture and authorizes the Trustee
to give it effect and appoints the Trustee as attorney-in-fact for such
purposes.

17. Trustee Dealings with Company.

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

18. No Recourse Against Others.

    No incorporator, stockholder, officer, director, employee or controlling
person as such, of the Company or of any successor Person thereof in such
capacity, shall have any liability for any obligations of the Company under the
Notes or the Indenture or for any claim based on, in respect of or by reason of,
such obligations or their creation.  Each Holder by accepting a Note waives and
releases all such liability.  Such waiver and release are part of the
consideration for the issuance of the Notes.

                                 EA-10

19. Authentication.

    This Note shall not be valid until the Trustee or authenticating agent
signs the certificate of authentication on the other side of this Note.

20. Holders' Compliance with Registration Rights Agreement.

    Each Holder of a Note, by acceptance hereof, acknowledges and agrees to the
provisions of the Registration Rights Agreement, including, without limitation,
the obligations of the Holders with respect to a registration and the
indemnification of the Company to the extent provided therein.

21. Abbreviations.

such as: TEN COM (= tenants in common), TEN ENT (= tenants by the entireties),
JT TEN (= joint tenants with right of survivorship and not as tenants in
common), CUST (= Custodian) and U/G/M/A (= Uniform Gifts to Minors Act).

22. Governing Law.

    The Indenture and the Notes shall be governed by the laws of the State of
New York, excluding (to the extent permissible by law) any rule of law that
would cause the application of the laws of any jurisdiction other than the State
of New York.

    The Company will furnish to any Holder upon written request and without
charge a copy of the Indenture.  Requests may be made to WinStar Communications,
Inc., 230 Park Avenue, Suite 2700, New York, NY 10169, Attention: General
Counsel.

Gentlemen:

         Reference is made to the proposed issuance by WinStar 
Communications, Inc. ("Company") of 15% Senior Subordinated Deferred Interest 
Exchange Notes ("Exchange Notes") under and pursuant to an indenture 
("Indenture") between the Company and United States Trust Company of New York 
("U.S. Trust"); and the proposed exchange of the Company's 15% Senior 
Subordinated Deferred Interest Notes ("Notes") for the Exchange Notes, 
pursuant to the Company's Registration Statement on Form S-4 ("Registration 
Statement"), filed by the Company with the Securities and Exchange Commission 
under the Securities Act of 1933, as amended, and the Trust Indenture Act of 
1939, as amended.

         We have examined such documents and considered such legal matters as 
we have deemed necessary and relevant as the basis for the opinion set forth 
below.  with respect to such examinations, we have assumed the genuineness of 
all signatures, the authenticity of all documents submitted to us as 
originals, the conformity to original documents of all documents submitted to 
us as reproduced or certified copies, and the authenticity of the originals 
of those latter documents.  As to questions of fact material to this opinion, 
we have, to the extent deemed appropriate, relied upon certain 
representations of certain officers and employees of the Company and its 
subsidiaries.

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

          1.     The Company is a corporation duly organized and existing 
under the laws of the State of Delaware.

         2.     The Exchange Notes have been duly and validly authorized by 
all necessary corporate action and will, when issued in accordance with the 
terms of the Indenture, constitute valid and binding obligations on the part 
of the Company and enforceable in accordance with their respective terms, 
except as may be limited by  bankruptcy, reorganization, insolvency or other 
similar laws of general application affecting the rights and remedies of 
creditors and secured parties and  the discretion of the courts in applying 
equitable principles.

         We hereby consent to the use of this opinion as Exhibit 5.1 to the 
Registration Statement, to the use of our name as counsel to the Company, and 
to all references made to us in the

amended, or the rules and regulations promulgated thereunder.

         Delivery of this Letter of Transmittal to an address other than as set
forth above or transmission of instructions via a facsimile transmission to a
number other than as set forth above will not constitute a valid delivery.

of 15% Senior Subordinated Deferred Interest Exchange Notes Due 2007 (the "New
Notes") of the Company for all outstanding 15% Senior Subordinated Deferred
Interest Notes Due 2007 (the "Old Notes") of the Company.  The terms of the New
Notes are identical to the terms of the Old Notes for which they may be
exchanged pursuant to the Exchange Offer, except that the New Notes will have
been registered under the Securities Act of 1933, as amended, and, therefore,
will not bear legends restricting the transfer thereof.

                        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 Notes. Subject to, and effective upon, the acceptance for exchange
of the Old 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 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 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 Notes and to acquire New Notes
issuable upon the exchange of such tendered Old Notes, and that, when the same
are accepted for exchange, the Company will acquire good and unencumbered title
to the tendered Old 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
Notes.

         The Exchange Offer is subject to certain conditions as set forth in
the Prospectus under the caption "Exchange Offer--Conditions to 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 may not be required to exchange any of the
Old Notes tendered hereby and, in such event, the Old 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 Notes represents to the Company that
(i) the New Notes acquired pursuant to the Exchange Offer are being obtained in
the ordinary course of business of the person receiving such New Notes, whether
or not such person is such Holder, (ii) neither the Holder of Old Notes nor any
such other person has an arrangement or understanding with any person to
participate in the distribution of such New  Notes, and (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 a distribution of the New
Notes.  If the tendering Holder is a broker-dealer that will receive New Notes
for its own account in exchange for Old Notes, it represents that the Old Notes
to be exchanged for the New Notes were acquired by it as a result of
market-making activities or other trading activities, and acknowledges that it
will deliver a prospectus meeting the requirements of the Securities Act in
connection with any resale of such New Notes.  By acknowledging that it will
deliver and by delivering a prospectus meeting the requirements of the
Securities Act in connection with any resale of such New Notes, the undersigned
is not deemed to admit that it is an "underwriter" within the meaning of the
Securities Act.

representatives, successors and assigns of the undersigned. Tendered Old Notes
may be withdrawn at any time prior to 5:00 p.m., New York City Time on the
Expiration Date.

Notes and any Old Notes delivered herewith but not exchanged, in each case

                                     INSTRUCTIONS

                       Forming Part of the Terms and Conditions
                                of the Exchange Offer

         1.   Delivery of this Letter of Transmittal and Certificates. 
Certificates for all physically delivered Old Notes, as well as a properly
completed and duly executed copy of this Letter of Transmittal or facsimile
thereof, and any other documents required by this Letter of Transmittal, must be
received by the Exchange Agent at any of its addresses set forth herein on or
prior to the Expiration Date.

         The method of delivery of this Letter of Transmittal, the Old Notes
and any other required documents is at the election and risk of the Holder and,
except as otherwise provided below, the delivery will be deemed made only when
actually received by the Exchange Agent.  Instead of delivery by mail, it is
recommended that Holders use an overnight or hand delivery service.

         Holders whose Old Notes are not immediately available or who cannot
deliver their Old Notes and all other required documents to the Exchange Agent
on or prior to the Expiration Date may tender their Old Notes pursuant to the
guaranteed delivery procedure set forth in the Prospectus under "Exchange
Offer--Procedures for Tendering."  Pursuant to such procedure:  (i) such tender
must be made by or through an Eligible Institution (as defined in the
Prospectus); (ii) on or prior to the Expiration Date, the Exchange Agent must
have received from such Eligible Institution a letter, telegram or facsimile
transmission setting forth the name and address of the tendering Holder, the
names in which such Old Notes are registered, and, if possible, the certificate
numbers of the Old Notes to be tendered; and (iii) all tendered Old Notes as
well as this Letter of Transmittal and all other documents required by this
Letter of Transmittal must be received by the Exchange Agent within three New
York Stock Exchange trading days after the date of execution of such letter,
telex, telegram or facsimile transmission, all as provided in the Prospectus
under the caption "Exchange Offer--Procedures for Tendering".

         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 Notes for exchange.

         2.   Partial Tenders; Withdrawals. Tenders of Old Notes will be
accepted in denominations of $1,000 and integral multiples in excess thereof. 
If less than the entire principal amount of Old 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 Notes submitted but not tendered
will be sent to such Holder as soon as practicable after the Expiration Date. 
All Old Notes delivered to the Exchange Agent will be deemed to have been
tendered unless otherwise indicated.



                                          8
<PAGE>



         Tenders of Old Notes pursuant to the Exchange Offer are irrevocable,
except that Old Notes tendered pursuant to the Exchange Offer may be withdrawn
at any time prior to 5:00 p.m., New York City time, on the Expiration Date. To
be effective, a written, telegraphic, telex 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 Notes to be withdrawn, the certificate numbers and designation of
the Old Notes to be withdrawn, the principal amount of Old Notes delivered for
exchange, a statement that such a Holder is withdrawing its election to have
such Old Notes exchanged, and the name of the registered Holder of such Old
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 Notes being withdrawn. The Exchange Agent will return the properly withdrawn
Old Notes promptly following receipt of notice of withdrawal.

         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 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 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 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 Notes.

         When this Letter of Transmittal is signed by the registered Holder or
Holders of Old 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 Notes listed, such Old 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
or Holders, in either case signed exactly as the name or names of the registered
Holder or Holders appear(s) on the Old 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.



                                          9
<PAGE>


         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 Notes are tendered: (i) by a registered
Holder of such Old Notes; or (ii) for the account of any Eligible Institution.

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

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

         7.   Requests for Assistance or Additional Copies.  Questions relating
to the procedure for tendering, as well as requests for additional copies of the
Prospectus and this Letter of Transmittal, may be directed to the Exchange Agent
at the address and telephone number set forth above.  In addition, all questions
relating to the Exchange Offer, as well as requests for assistance or additional
copies of the Prospectus and this Letter of Transmittal, may be directed to the
Exchange Agent at the address specified in the Prospectus.

         8.   Irregularities.  All questions as to the validity, form,
eligibility (including time of receipt), and acceptance of Letters of
Transmittal or Old 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 Notes covered by any Letter of Transmittal or
tendered pursuant to such Letter of Transmittal. 


                                          10

None of the Company, the Exchange Agent or any other person will be under any 
duty to give notification of any defects or irregularities in tenders or

Company's interpretation of the terms and conditions of the Exchange Offer 
shall be final and binding.

         9.   Definitions.  Capitalized terms used in this Letter of
Transmittal and not otherwise defined have the meanings given in the Prospectus.
