            ICG Services, Inc., a Delaware corporation (the "Company"),
          hereby offers upon the terms and subject to the conditions set
          forth in this Prospectus and the accompanying Letter of
          Transmittal (the "Letter of Transmittal"), to exchange (the
          "Exchange Offer") its outstanding 10% Senior Discount Notes due
          2008 (the "Old Notes"), of which an aggregate of $490,000,000 in
          principal amount at maturity is outstanding as of the date
          hereof, for an equal principal amount of newly issued 10% Senior
          Exchange Discount Notes due 2008 (the "New Notes").  The form and
          terms of the New Notes will be the same as the form and terms of
          the Old Notes except that the New Notes will be registered under
          the Securities Act of 1933, as amended (the "Securities Act"),
          and will not bear legends restricting the transfer thereof. The
          New Notes will be entitled to the benefits of the Indenture,
          dated as of February 12, 1998, governing the Notes (the
          "Indenture"). The New Notes and the Old Notes are sometimes
          referred to herein collectively as the "Notes" or the "Senior
          Discount Notes." 
                               (Continued on next page)

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

          SEE "RISK FACTORS" AT PAGE 14 FOR A DISCUSSION OF CERTAIN RISKS
          THAT SHOULD BE CONSIDERED BY ELIGIBLE HOLDERS IN EVALUATING THE
          EXCHANGE OFFER.

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

            THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE
              SECURITIES AND EXCHANGE COMMISSION OR ANY STATE SECURITIES
              COMMISSION NOR HAS THE SECURITIES AND EXCHANGE COMMISSION
                 OR ANY STATE SECURITIES COMMISSION PASSED UPON THE 
                    ACCURACY OR ADEQUACY OF THIS PROSPECTUS.  ANY 
                         REPRESENTATION TO THE CONTRARY IS A
                                  CRIMINAL OFFENSE.

     


          There will not be any payment of interest on the New Notes prior
          to August 15, 2003. Interest on the New Notes will be paid in
          cash at the rate of 10% per annum on each February 15 and August
          15, commencing August 15, 2003, to holders of record on the
          immediately preceding February 1 and August 1, respectively. The
          Company is a wholly owned subsidiary of ICG Communications, Inc.,
          a Delaware corporation ("ICG").  Prior to this Exchange Offer
          there has been no public market for any securities of the Company
          and there can be no assurance that such a market will develop.
          See "Description of the New Notes."  

            On or after February 15, 2003, the New Notes are redeemable, at
          the option of the Company, in whole or in part from time to time,
          at the redemption prices set forth herein, plus accrued and
          unpaid interest to the date of redemption.  Upon a Change of
          Control (as herein defined), the Company is required to make an
          offer to purchase the Notes at a purchase price equal to 101% of
          their Accreted Value on the date of purchase plus accrued
          interest. At March 31, 1998, the Company had, on an
          unconsolidated basis, approximately $304.4 million of senior
          indebtedness including the New Notes, and the subsidiaries of the
          Company had, on an unconsolidated basis, an aggregate of
          approximately $6.1 million of senior indebtedness, consisting
          solely of capital lease obligations.

            At any time prior to February 15, 2001, the Company may, at its
          option, redeem New Notes having an aggregate principal amount of
          up to 35% of the aggregate principal amount of all New Notes
          originally issued, at a redemption price equal to 110% of the
          Accreted Value thereof on the date of redemption, plus accrued
          and unpaid interest, with the proceeds of one or more public or
          private Equity Offerings (as defined herein), provided that after
          any such redemption at least 65% of the aggregate principal
          amount of the New Notes initially used remains outstanding.

            The Company will accept for exchange any and all Old Notes
          which are properly tendered in the Exchange Offer prior to 5:00
          p.m., New York City time, on           , 1998 (if and as 
                                       ----------
          extended, the "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. Old Notes may be tendered only in integral
          multiples of $1,000.

            Based on a previous interpretation by the staff of the
          Securities and Exchange Commission (the "Commission") set forth
          in no-action letters to third parties, the Company believes that
          the New Notes pursuant to the Exchange Offer may be offered for
          resale, resold and otherwise transferred by a holder thereof
          (other than (i) a broker-dealer who purchases such New Notes
          directly from the Company to resell pursuant to Rule 144A or any
          other available exemption under the Securities Act or (ii) a
          person that is an affiliate of the Company (within the meaning of
          Rule 405 under the Securities Act)) without compliance with the
          registration and prospectus delivery provisions of the Securities
          Act, provided that the holder or any other such person is
          acquiring the New Notes in its ordinary course of business and is
          not participating, and has no arrangement or understanding with
          any person to participate, in the distribution of the New Notes. 
          Holders of Old Notes wishing to accept the Exchange Offer must
          represent to the Company 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, 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 90 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."

            The Company believes that none of the registered holders of the
          Old Notes is an affiliate (as such term is defined in Rule 405
          under the Securities Act) of the Company. Prior to this Exchange
          Offer, there has been no public market for the Old Notes.  The
          Company does not intend to list the New Notes on any securities
          exchange or to seek approval for quotation through any automated
          quotation system. There can be no assurance that an active market
          for the New Notes will develop. To the extent that a market for
          the New Notes does develop, the market value of the New Notes
          will depend on market conditions (including yields on alternative
          investments), general economic conditions, the Company's
          financial condition and other conditions.  Such conditions might
          cause the New Notes, to the extent that they are actively traded,
          to trade at a significant discount from face value. The Company


                                     2
     


          has not entered into any arrangement or understanding with any
          person to distribute the New Notes to be received in the Exchange
          Offer.

            The Company will not receive any proceeds from the Exchange
          Offer. The Company has agreed to bear the expenses of the
          Exchange Offer. No underwriter is being used in connection with
          the Exchange Offer. The New Notes have not been rated by a
          nationally recognized statistical rating organization.

                  The date of this Prospectus is            , 1998.
                                                 -----------

                                     THE COMPANY

             ICG Services, Inc. provides Internet services, through its
          subsidiary, NETCOM, to individuals and to small and medium-sized
          businesses. The Company also acquires telecommunications
          equipment, software and capacity for lease or sale to other
          subsidiaries of ICG. In addition to providing these services, the
          Company intends to grow through acquisitions of
          telecommunications, Internet and related businesses that
          complement ICG's business strategy.

             The Company is a wholly owned subsidiary of ICG, one of the
          nation's leading integrated communications providers ("ICPs") of
          competitive communications services, based on estimates of the
          industry's 1997 revenue. ICPs seek to provide an alternative to
          incumbent local exchange carriers ("ILECs"), long distance
          carriers, Internet service providers ("ISPs") and other
          communications providers for a full range of communications
          services in the increasingly deregulated telecommunications
          industry.  ICG's objectives are to provide a wide range of local,
          long distance and data communications services to business end
          users and wholesale customers and to be a premier provider of
          high quality communications services to its targeted business and
          carrier customers. ICG believes that customers are increasingly
          demanding a broad, full service approach to providing services
          and that, by offering a bundled package, ICG will be better able
          to capture business from communications-intensive commercial
          customers.

             The principal executive offices of the Company are located at
          161 Inverness Drive West, Englewood, Colorado 80112; its
          telephone number is 303-414-5000.

                                  BUSINESS STRATEGY

             The Company's objective is to acquire and consolidate
          telecommunications, Internet and related businesses and bundle
          the services provided by these businesses with ICG's current
          competitive local and long distance telecommunications products.
          By leveraging the Company's relationship with ICG and utilizing
          ICG's extensive network footprint, the Company intends to capture
          the growth in demand from business customers for a full package
          of telecommunications services by offering a wide array of
          services including Internet services.

             Market Services to Business End Users. The Company is focused
          on marketing a variety of telecommunications and Internet
          products and services primarily to business end users. Through
          its wholly owned subsidiary, NETCOM, the Company currently
          markets Internet services to individuals and to small and medium-
          sized businesses. In January 1997, NETCOM announced plans to
          migrate its customer focus away from high volume, low margin
          consumer customers to higher margin products for small and
          medium-sized business customers. Management believes a targeted
          business end user strategy can better leverage ICG's network
          footprint and telecommunications investment. To date, NETCOM has


                                      -3-
     


          been successful in implementing this plan, and has seen its
          average revenue per customer increase from $21.47 during fiscal
          1996 to $23.92 during fiscal 1997.

             Concentrate on Regional Clusters. The Company believes that by
          focusing its growth on business activities located within ICG's
          network of regional clusters in California, Colorado, Ohio and
          the Southeast, it will be able to more effectively service its
          customers' needs and efficiently market, operate and control its
          network and expanded service offerings. In addition, the Company
          believes that by focusing future growth within ICG's existing
          footprint, it will be able to overlay ICG's support services and
          realize extensive cost synergies. For example, a significant
          portion of NETCOM's customer base is located in California. To
          the extent feasible, NETCOM will route its Internet traffic over
          ICG's California network. NETCOM plans to continue to operate and
          grow its business in the United States outside of ICG's network
          footprint and in Canada and the United Kingdom.

             Increase Revenue and Margins through Bundled Services. The
          Company intends to increase its revenue and margins by providing
          a full range of communications products to its end user
          customers. The Company plans to complement ICG's competitive
          local and long distance telecommunications offerings by combining
          the Internet products developed by NETCOM and cross-marketing
          these combined products through ICG's direct sales force.
          Additionally, NETCOM intends to market ICG telecommunications
          products to its small and medium-sized business customer base.

             Integrate Investments and Expand. The Company expects to
          acquire telecommunications, Internet and related businesses that
          complement ICG's business strategy to offer a wide array of
          telecommunications, Internet and related services, primarily to
          business customers. Acquisition targets could include U.S. and
          foreign competitive local exchange carriers ("CLECs"), ISPs and
          long distance companies, among others.  The Company intends to
          make future acquisitions primarily through the use of common
          stock of ICG ("ICG Common Stock"), cash on hand and the proceeds
          from securities offerings.

             ICG and the Company believe that the acquisition of NETCOM is
          strategically important as it helps to (i) broaden ICG's
          communications product offerings to include Internet services and
          (ii) provide NETCOM with extensive network infrastructure for the
          on-net transportation of its Internet traffic. The Company will
          continue to look for acquisitions which it believes will further
          ICG's objectives to provide a wide range of local, long distance
          and data communications services to business end users and
          wholesale customers and to be a premier provider of high quality
          communications services to its targeted business and carrier
          customers.

                                        NETCOM

             NETCOM is a leading provider of high quality Internet
          solutions to individuals and small and medium-sized businesses in
          the United States and also provides the same high quality
          Internet solutions in Canada and the United Kingdom. NETCOM
          offers a broad spectrum of Internet solutions designed to enhance
          customer productivity through the integration and application of
          technologies by providing a comprehensive software platform to
          interface with the World Wide Web (the "Web"), premium quality
          Internet access and support services and on-line tools to
          automate Web site creation and development. These offerings have
          led to significant growth, with revenue increasing from
          approximately $2.4 million for 1993 to approximately $160.7
          million for fiscal 1997. In January 1997, NETCOM announced plans
          to migrate its customer focus away from high volume, low margin
          consumer customers to higher margin products for small and
          medium-sized business customers.

             NETCOM owns and operates a data communications network
          consisting of 17 hubs containing frame relay switches and high-
          performance routers connecting a backbone of leased Asynchronous
          Transfer Mode ("ATM") switches and leased high-speed dedicated
          data lines in the United States, Canada and the United Kingdom.
          NETCOM maintains 247 points-of-presence ("POPs") in the United
          States and Canada and also offers virtual local access numbers in
          Canada and the United Kingdom. The design and architecture of the
          physical network permits NETCOM to offer highly flexible,
          reliable high-speed services to its customers and support
          significant subscriber growth. The NETCOM infrastructure is
          monitored by network operations centers ("NOCs") in San Jose,
          California, Dallas, Texas, Toronto, Canada and London, England.


                                      -4-
     


             NETCOM provides Internet solutions principally through dial-
          up, direct access and Web site hosting services. Direct access
          and Web site hosting services provide higher revenue per customer
          and higher margins than dial-up services. NETCOM also receives
          revenue from value-added services such as security, anti-virus
          and data storage.

             Dial-Up Services. NETCOM's dial-up customers receive an
          integrated Internet solution consisting of high quality access,
          software and 24 hours a day, seven days a week, automated
          customer support. NETCOM dial-up customers connect directly to
          the Internet via NETCOM's network which provides high speed,
          reliable access. All NETCOM dial-up accounts allow access to the
          Internet's resources, including E-mail, the Web and USENET
          newsgroups. In addition, NETCOM dial-up customers can receive a
          one megabyte ("Mb") personal Web page, access to a daily
          customized newspage via E-mail, and access to on-line financial,
          corporate and market information and analytical tools. Enhanced
          services available to dial-up customers include features such as
          additional E-mail addresses, enhanced support offerings, software
          and virus updates, access to research libraries, domain name
          service, monthly back-up, 10 Mb data storage, 750 Mb per month
          data transfer capability and premium service and technology
          support.

             NETCOM customers can quickly register using NETCOMplete
          software, available for both Windows and Macintosh platforms via
          compact disk, and set up a NETCOM account by following a sequence
          of simple, on-screen steps. All of the software needed to connect
          and access the Internet is automatically installed and
          configured, eliminating the need for complex set up procedures.
          NETCOMplete also provides an easy-to-use interface as well as
          software from leading industry participants, bookmark managers,
          off-line browsers and additional software that enhances a
          customer's Internet experience. Revenue from dial-up services
          increased from $102.9 million for fiscal 1996 to $133.7 million
          for fiscal 1997, representing approximately 85% and 83%,
          respectively, of total revenue for such periods.

             Direct Access Services. NETCOM offers a full suite of high-
          speed dedicated Internet connection and service products which
          provide its small and medium-sized business customers with direct
          access to the full range of Internet applications. These Internet
          services are offered to businesses over leased lines at various
          speeds, including 56 Kbps, T-1 and T-3 levels, depending upon the
          customer's needs. Through its direct access product line, NETCOM
          offers Internet access services including domain name and
          Internet Protocol ("IP") address, router configurations, on-line
          usage statistics and security consultation. There are generally
          no usage charges for any of NETCOM's dedicated customers, and E-
          mail service and USENET news feed are provided at no additional
          charge. Direct network connection requires the customer to obtain
          a leased line from ICG or another local telephone company. NETCOM
          provides an Internet connection based on frame relay technology
          provided by local telephone carriers. Revenue from direct access
          services increased from $16.3 million for fiscal 1996 to $19.5
          million for fiscal 1997, representing approximately 14% and 12%,
          respectively, of total revenue for such periods.

             Web Site Hosting Services. NETCOM offers Web site hosting
          services to its small and medium-sized business customers as well
          as to individuals. Web site hosting services include client
          domain name registration, hosting and site maintenance. Services
          provided are fully scalable but would, in a typical package,
          include domain name registration, 10 E-mail addresses, access to
          NETCOM's on-line Business Center, CGI scripting (which enables
          visitors to the Web site to leave their names and addresses),
          weekly back-up service, 50 Mb of data storage, 1,000 Mb per month
          of data transfers, traffic logs and Web statistics and premium
          service and technology support. Revenue from Web site hosting
          services increased from $1.3 million for fiscal 1996 to $6.3
          million for fiscal 1997, representing approximately 1% and 4%,
          respectively, of total revenue for such periods.

             Value-Added Services. As part of its dial-up, direct access
          and Web site hosting services, NETCOM offers its small and
          medium-sized business customers value-added business connectivity
          solutions packages designed to address their needs of increased
          security, reliability, access speed and customer service. The
          Company believes that businesses are willing to pay premium
          prices for these premium services. One such feature is Automatic
          Reconnect which automatically re-routes customers' traffic to an
          alternate Integrated Services Digital Network ("ISDN") line so
          that in the event of certain kinds of service interruptions
          customers may remain connected. In order to provide a secure,
          private connection among multiple specific locations, NETCOM's
          SecureConnect product performs a security assessment and then
          implements, monitors and troubleshoots a flexible security
          solution to provide secure communication between central offices,
          branch offices and off-site employees without jeopardizing the


                                      -5-
     


          integrity of the internal network. Another value-added service
          NETCOM offers is 24 hours a day, seven days a week support. For
          larger customers, NETCOM offers flexible, high-speed dedicated
          line service that is scalable to grow as traffic increases. Other
          value-added services offered include password protected Web
          sites, usage statistics, anti-virus software and additional
          domain names.

                                 RECENT DEVELOPMENTS

             On January 21, 1998, NETCOM was merged with a subsidiary of
          ICG in a business combination accounted for as a pooling-of-
          interests. NETCOM is a wholly owned subsidiary of the Company.
          Based upon the closing price of ICG Common Stock on such date of
          $26.25 and NETCOM's diluted shares outstanding (using the
          treasury stock method), the aggregate purchase price was
          approximately $285 million.  Based on the Company's preliminary
          internal review, it expects revenue and EBITDA losses for the
          quarter ended March 31, 1998 to be approximately $40.5 million
          and $.8 million, respectively.  All revenue was derived from
          NETCOM and $.5 million of EBITDA losses related to the allocation
          of general and administrative expenses from ICG.  Financial
          results for the quarter ended March 31, 1998 were affected
          primarily by revenue derived from NETCOM's dial-up and direct
          access products.  Dial-up revenue was partially affected by the
          lack of an industry-wide modem standard, which has since been
          resolved, as well as delayed advertising programs, which NETCOM
          expects to implement in the second quarter.  Direct access
          revenue was affected primarily by lower than expected set-up and
          equipment revenues, as well as greater sales of lower end
          dedicated lines, which generate lower revenue than higher speed
          T-1 lines.

             ICG Equipment was formed as a wholly owned subsidiary of the
          Company in January 1998.  ICG enters into arrangements with ICG
          Equipment to purchase or lease telecommunications equipment,
          software and capacity and related services.  The equipment and
          services provided to ICG will be utilized to upgrade and expand
          its network infrastructure to take full advantage of the
          opportunities and cost savings available as a result of the
          acquisitions made by the Company.  Any such arrangements will be
          on an arm's length basis and on comparable terms that ICG would
          be able to obtain from a third party.

             In February 1998, the Company completed a private offering
          (the "Private Offering") of the Old Notes.  The net proceeds from
          the Private Offering were approximately $291.6 million, net of
          underwriting commissions.  Cash interest on the Old Notes accrues
          at 10% per annum beginning February 15, 2003 and is payable each
          February 15 and August 15, commencing August 15, 2003.  The Old
          Notes will be redeemable at the option of the Company, in whole

             In March, 1998, ICG announced its plans to offer long distance
          service via IP technology.  ICG and NETCOM will begin to market
          this service over the Internet and through an inbound
          telemarketing center in the second quarter of 1998.  ICG also
          plans to offer by the end of fiscal 1998 competitively priced
          high-speed data transmission services via digital subscriber line
          ("DSL") technology to all business and end user customers within
          its existing regional clusters.  DSL technology utilizes the
          existing twisted copper pair connection to the business or end
          user, giving the customer significantly greater bandwidth when
          connecting to the Internet.

                               ICG COMMUNICATIONS, INC.

             ICG is one of the nation's leading ICPs of competitive
          communications services, based on estimates of the industry's
          1997 revenue. ICPs seek to provide an alternative to ILECs, long
          distance carriers, ISPs and other communications providers for a
          full range of communications services in the increasingly
          deregulated telecommunications industry. Through its CLEC
          operations, ICG operates networks in four regional clusters
          covering major metropolitan statistical areas in California,
          Colorado, Ohio and the Southeast. ICG also provides a wide range
          of network systems integration services, maritime and
          international satellite transmission services and, through the
          Company, a variety of Internet connectivity and other value-added
          Internet services.  As a leading participant in the rapidly
          growing competitive local telecommunications industry, ICG has
          experienced significant growth, with total revenue increasing
          from approximately $111.6 million for the fiscal year ended
          September 30, 1995 to approximately $273.4 million for the fiscal
          year ended December 31, 1997.

             The Company is a wholly owned subsidiary of ICG; however, due
          to restrictions imposed on ICG by certain indentures and certain
          preferred stock provisions (collectively, "ICG Indentures")
          related to prior financings, ICG and ICG's Restricted

          Subsidiaries are also prohibited from engaging in transactions
          with the Company other than on an arm's length basis, and if the
          proposed transaction exceeds $2 million in value, ICG and its
          Restricted Subsidiaries may only participate with the approval of
          a majority of the disinterested members of the Board of Directors
          of ICG or with a written opinion of a nationally recognized

          ICG from a financial point of view. See "Certain Relationships

             Exchange Offer .   The Company may terminate the Exchange
                                Offer if it determines that its ability to
                                proceed with the Exchange Offer could be
                                materially impaired due to any legal or
                                governmental action, any new law, statute,
                                rule or regulation, any interpretation by

                                of governmental agencies or holders of the

          Certain Federal
             Income Tax         The exchange of New Notes for Old Notes
             Considerations .   will not constitute a taxable event for
                                U.S. federal income tax purposes. As a
                                result, holders of New Notes will not
                                recognize any income, gain or loss with
                                respect to such exchange. The New Notes
                                will be issued with original issue discount
                                ("OID") for U.S. federal income tax
                                purposes. United States Holders of New
                                Notes issued with OID must include such OID
                                in income on a constant yield accrual
                                method, regardless of such holders' method
                                of accounting. As a result, such holders

                                will be issued (the "Indenture") will
                                contain certain covenants which, among
                                other things, will restrict the ability of
                                the Company and its Restricted Subsidiaries
                                (as defined herein) 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 make
                                certain other restricted payments; sell
                                assets; create restrictions on the ability

                                assets. The Indenture will contain
                                significant exceptions to these covenants.

                                purchase price equal to 101% of their
                                Accreted Value on the date of purchase plus
                                accrued interest, if any. See "Description

                                SUMMARY FINANCIAL DATA

             The Company is a newly formed Delaware corporation and,
          accordingly, no financial statements for the Company have been
          included herein. NETCOM is a wholly owned subsidiary of the
          Company, acquired in a pooling-of-interests transaction with ICG.

             The following table sets forth summary financial and other
          operating data of NETCOM, the predecessor to the Company, for
          each fiscal year in the five-year period ended December 31, 1997.
          Such data have been derived from, and should be read in
          conjunction with, NETCOM's audited consolidated financial
          statements and notes thereto included elsewhere in this
          Prospectus for each of the fiscal years in the three-year period
          ended December 31, 1997.  NETCOM's development and expansion
          activities, including acquisitions, during the periods shown
          below materially affect the comparability of this data from one
          period to another.

                                         YEARS ENDED DECEMBER 31,

               Professional Internet Consulting, Inc., which was acquired
               by NETCOM in August 1995.
          (2)  Giving pro forma effect to the receipt of the net proceeds
               from the Private Offering and interest expense, net on
               $300.6 million gross proceeds of Notes, without giving any
               effect to any increased interest income on available cash,
               as if such events had occurred on January 1, 1997, interest
               expense, net would have been $26.6 million for fiscal 1997.
          (3)  Capital expenditures include assets acquired under capital
               leases. 
          (4)  Earnings before interest, taxes, depreciation and
               amortization ("EBITDA") is provided because it is a measure
               commonly used in the Internet and telecommunications
               industries. EBITDA is presented to enhance the understanding
               of NETCOM's operating results and is not intended to
               represent cash flows or results of operations in accordance
               with generally accepted accounting principles ("GAAP") for
               the periods indicated. EBITDA is not a measurement under
               GAAP and is not necessarily comparable with similarly titled
               measures of other companies. Net cash flows from operating,
               investing and financing activities as determined using GAAP
               are also presented in Other Data.
          (5)  Earnings were insufficient to cover fixed charges in 1994,
               1995, 1996 and 1997 by $.1 million, $14.0 million, $44.2
               million and $33.1 million, respectively. On a pro forma
               basis giving effect to the Private Offering as if it had
               occurred on January 1, 1997 and without giving effect to any
               increased interest income on additional available cash,
               earnings would have been insufficient to cover fixed charges
               by $63.1 million for fiscal 1997. Earnings consist of income
               (loss) before provision for income taxes plus fixed charges.
               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 rental expense the Company believes to be
               representative of interest (i.e., one-third of rental
               expense).

                                     RISK FACTORS

             An investment in the New Notes offered hereby involves a high
          degree of risk. The following risk factors, together with the
          other information set forth in this Prospectus should be
          considered when evaluating an investment in the Company. This
          Prospectus includes certain forward-looking statements. The
          discussion set forth below contains cautionary statements
          identifying important factors including, but not limited to, the
          Company's lack of operating history, historical operating losses
          of NETCOM and lack of credit support from ICG, that could cause
          actual results to differ materially from the forward-looking
          statements.

          LACK OF OPERATING HISTORY; HISTORICAL OPERATING LOSSES OF NETCOM

             The Company has been recently formed, has no operating history
          and has only owned NETCOM since January 1998. NETCOM has incurred
          and expects to continue to incur significant operating and net
          losses for the near term. NETCOM had net losses and EBITDA losses
          of approximately $33.1 million and $1.7 million, respectively,
          for fiscal 1997.  There can be no assurance that the Company will
          achieve or sustain profitability or positive EBITDA in the future
          or at any time have sufficient resources to make principal and
          interest payments on the New Notes. See "Selected Financial
          Data," including the notes thereto, and "Management's Discussion
          and Analysis of Financial Condition and Results of Operations."

          LACK OF CREDIT SUPPORT FROM ICG

             ICG is a guarantor under the ICG Indentures pursuant to which
          ICG's subsidiaries, ICG Holdings, Inc. and ICG Funding, LLC, have
          obtained outstanding financing through offerings of senior
          discount notes in the aggregate accreted amount of $887.5 million
          and redeemable preferred securities with a liquidation value of
          $434.6 million at December 31, 1997. The ICG Indentures impose
          severe restrictions on the relationship between ICG and its
          subsidiaries that are designated by ICG as Unrestricted
          Subsidiaries (as defined in the ICG Indentures). The Company is a
          wholly owned subsidiary of ICG which has been designated as an
          Unrestricted Subsidiary by ICG, and, as a result, ICG and its
          Restricted Subsidiaries are prohibited from providing cash or
          credit support to the Company or the Company's subsidiaries. ICG
          and its Restricted Subsidiaries are also prohibited from engaging
          in transactions with the Company or the Company's subsidiaries
          other than on an arm's length basis, and if a proposed
          transaction exceeds $2 million in value, ICG and its Restricted
          Subsidiaries may only participate with the approval of a majority
          of the disinterested members of the Board of Directors of ICG or
          the written opinion of a nationally recognized investment banking
          firm stating that the transaction is fair to ICG from a financial
          point of view. These restrictions could impair the Company's
          ability to raise capital, enter into arrangements with vendors,
          and conduct its business, which could have a material adverse
          effect on the Company's business, growth, financial condition and
          results of operations and ability to make payments on the New
          Notes.

             With respect to arrangements that ICG Equipment enters into
          with ICG to sell or lease under operating leases, licenses or
          rights-of-use for telecommunications equipment, software and
          capacity and related services, the Company depends upon ICG for
          payments from such transactions. As of December 31, 1997, ICG
          had, on a consolidated basis, aggregate accreted indebtedness,
          including capitalized lease obligations, of approximately $968.1
          million. For the 12 months ended December 31, 1997, ICG had
          interest expense of approximately $117.5 million and EBITDA
          losses of approximately $123.8 million.  In the event ICG were
          unable to make payments under such arrangements, it would have a
          material adverse effect on the Company's business, financial
          condition and results of operations and ability to make payments
          on the New Notes. See "Certain Relationships and Related
          Transactions" and "Risk Factors -- Certain Financial and
          Operating Restrictions."


                                      -14-
     


          SUBSTANTIAL INDEBTEDNESS; ABILITY TO SERVICE DEBT

             At December 31, 1997, on a pro forma basis giving effect to
          the Private Offering and the acquisition of NETCOM, the Company
          would have had, on a consolidated basis, approximately $306.6
          million of indebtedness, including capitalized lease obligations.
          The accretion of original issue discount on the New Notes will
          cause an increase in indebtedness of approximately $65 million by
          February 15, 2000.  The Indenture permits the incurrence of
          substantial amounts of additional indebtedness by the Company and
          its subsidiaries. The Company anticipates that it and/or its
          subsidiaries may incur substantial additional indebtedness in the
          future.

             The level of the Company's indebtedness could have important
          consequences to holders of the New Notes including the following:
          (i) the debt service requirements of any additional indebtedness
          could make it more difficult for the Company to make payments on
          the New Notes; (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 other purposes; (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 some of its competitors, which may
          place it at a competitive disadvantage; and (vi) the Company's
          high degree of indebtedness will make it more vulnerable in the
          event of a downturn in its business.

             The Company, on a pro forma basis, has experienced EBITDA
          losses. NETCOM's earnings before fixed charges were insufficient
          to cover fixed charges for fiscal 1997 by $33.1 million.  For the
          same period on a pro forma basis after giving effect to the
          Private Offering, the Company's earnings before fixed charges
          would have been insufficient to cover fixed charges by $63.1
          million. In addition, for the same period on the same pro forma
          basis, NETCOM's EBITDA minus capital expenditures and interest
          expense would have been $49.5 million.  There can be no assurance
          that the Company will be able to improve its earnings before
          fixed charges or that the Company will be able to meet its debt
          service obligations, including its obligations on the New Notes.
          In the event the Company's cash flow is inadequate to meet its
          obligations, the Company could face substantial liquidity
          problems. If the Company is unable to generate sufficient cash
          flow or otherwise obtain funds necessary to make required
          payments, or if the Company otherwise fails to comply with the
          various covenants in its indebtedness, it would be in default
          under the terms thereof, which would permit the holders of such
          indebtedness to accelerate the maturity of such indebtedness and
          could cause defaults under other indebtedness of the Company.
          Such defaults could result in a default on the New Notes and
          could delay or preclude payment of principal of, or interest on,
          the New Notes. The ability of the Company to meet its obligations
          will be dependent upon the future performance of the Company and
          upon receiving payments from ICG which will be subject to
          prevailing economic conditions and to financial, business and
          other factors, including ICG's results and other factors, beyond
          the control of the Company. See "-- Lack of Credit Support from
          ICG."

          RISKS RELATED TO POTENTIAL REQUIREMENT TO PAY ACCESS CHARGES OR
          CONTRIBUTE TO FEDERAL UNIVERSAL FUND

             Although the Company is not currently subject to direct
          regulation by the Federal Communications Commission ("FCC") or
          any other governmental agency, it is possible that the Company
          and other ISPs could become subject to regulation by the FCC or
          another regulatory agency as a provider of basic
          telecommunications services.  The FCC is currently considering
          whether ISPs should be required to pay access charges to local
          telephone companies for each minute that dial-access users spend
          connected to ISPs through telephone company switches.  In
          addition, some telephone companies are seeking relief through
          state regulatory agencies.  The FCC may also decide that ISPs
          should contribute to the federal Universal Service Fund.  Such
          requirements, if adopted at either the federal or the state
          level, would have a material adverse effect on the Company's
          business, financial condition and results of operations and its
          ability to make payments on the New Notes.  See "--Regulation."


                                      -15-
     


          INTEGRATION OF ACQUIRED BUSINESSES

             The Company intends to grow through expansion of its existing
          operations, integration with ICG and through acquisitions of U.S.
          or foreign businesses. The Company's ability to manage its
          existing businesses and its anticipated future growth will depend
          on its ability to evaluate new markets and investment vehicles,
          monitor operations, control costs, maintain effective quality
          controls, and significantly expand the Company's internal
          management, technical and accounting systems. The Company's
          integration with ICG and planned future growth will place a
          significant strain on the Company's financial, management and
          operational resources, including the identification of
          acquisition targets and the negotiation of acquisition
          agreements. In addition, acquisitions may entail considerable
          expenses in advance of anticipated related revenue and may cause
          fluctuations in the Company's operating results.

             In addition, upon the acquisition of other businesses, such
          acquired businesses will need to be integrated with the Company's
          existing businesses and its then existing operations. For
          acquired businesses, this may entail, among other things,
          integration of switching, transmission, technical, sales,
          marketing, billing, accounting, quality control, management,
          personnel, payroll, regulatory compliance and other systems and
          operating hardware and software, some or all of which may be
          incompatible. The Company may also need to address cultural,
          linguistic and legal concerns for acquired foreign businesses.
          The failure to effectively integrate acquired businesses could
          have a material adverse effect on the Company's business, growth,
          financial condition and results of operations and ability to make
          payments on the New Notes.

             The Company expects to use a portion of the proceeds of the
          Private Offering to continue acquiring telecommunications,
          Internet and related businesses that complement ICG's business
          strategy to offer a wide array of telecommunications, Internet
          and related services, primarily to communications intensive
          business customers. Acquisition targets could include U.S. or
          foreign CLECs, ISPs and long distance companies, among others. 
          The Company intends to make future acquisitions primarily through
          the use of ICG Common Stock, cash on hand and the proceeds from
          securities offerings.

             The Company may in the future experience a strain on its
          management, operations and financial resources as a result of
          growth and acquisitions. The Company's ability to effectively
          manage growth will require it to continue to implement and
          improve its operational, financial and management information
          systems and to train, motivate and manage its employees, as well
          as to expand its existing direct access services business. These
          demands will require the addition of new management personnel and
          the development of additional expertise by existing management.
          In particular, the demands on NETCOM's data communications
          infrastructure and customer support resources have grown rapidly
          with NETCOM's changing subscriber base, and NETCOM may experience
          difficulties meeting the demand for its connectivity services.
          Capacity constraints may occur, both at the level of particular
          local access numbers and in connection with system-wide services
          that are provided from NETCOM's NOCs. NETCOM has experienced
          difficulties in providing an adequate level of customer service
          and support, and has been taking steps to improve its data
          communications infrastructure and customer support resources. A
          failure to enhance customer support resources adequately, or to
          expand and enhance its data communications infrastructure
          adequately, may materially adversely affect the Company's
          business, operating results, financial condition and ability to
          make payments on the New Notes. There can be no assurance that
          the Company's customer support or other resources will be
          sufficient to manage any future growth in its business or that
          NETCOM will be able to implement in whole or in part its
          expansion program, and any failure to do so could have a material
          adverse effect on the Company's business, operating results,
          financial condition and its ability to make payments on the New
          Notes.

             Although the Company expects to invest significant resources
          in NETCOM's data communications infrastructure and customer
          support resources, NETCOM continues to experience attrition of
          its subscribers from time to time as a result of a number of
          factors, including difficulties associated with management of
          growth and the shift of its focus to business customers. There
          can be no assurance that the Company will be able to improve its
          ability to retain subscribers or to attract sufficient new
          subscribers to offset periodic losses of existing subscribers.


                                      -16-
     

          COMPETITION

             The market for Internet access and related services is highly
          competitive. There are no substantial barriers to entry and the
          Company anticipates that competition will continue to intensify
          as the use of the Internet grows. The tremendous growth and
          potential market size of the Internet access market has attracted
          many new start-ups as well as existing businesses from different
          industries. Current and prospective competitors include, in
          addition to other national, regional and local ISPs, long
          distance and local exchange telecommunications companies, cable
          television, direct broadcast satellite, wireless communications
          providers, and on-line service providers.

             ISPs. According to industry sources, there are over 4,300 ISPs
          in the United States and Canada as of October 31, 1997,
          consisting of national, regional and local providers. The
          Company's current primary competitors include other ISPs with a
          significant national presence which focus on business customers,
          such as UUNet Technologies, Inc. ("UUNet"), Bolt, Beranek &
          Newman, Inc. ("BBN") and Performance Systems International,
          Inc.("PSINet"). While the Company believes that its level of
          local service and support and target market focus distinguish it
          from these competitors, many of these competitors have
          significantly greater market share, brand recognition, and
          financial, technical and personnel resources than the Company.
          The Company also competes with unaffiliated regional and local
          ISPs in its targeted geographic regions.

             Telecommunications Carriers. The major long distance companies
          (also known as interexchange carriers or IXCs), including AT&T
          Corporation ("AT&T"), MCI Communications Corp. ("MCI"), and
          Sprint Corporation ("Sprint"), offer Internet access services and
          compete with the Company. The recent sweeping reforms in the
          federal regulation of the telecommunications industry have
          created greater opportunities for ILECs, including the RBOCs and
          other competitive CLECs, to enter the Internet connectivity
          market. In order to address the Internet connectivity
          requirements of the business customers of long distance and local
          carriers, the Company believes that there is a move toward
          horizontal integration by ILECs through acquisitions or joint
          ventures with and the wholesale purchase of connectivity from
          ISPs. The WorldCom, Inc. ("WorldCom")/MFS Communications,
          Inc./UUNet consolidation and GTE Corporation's ("GTE") recent
          acquisition of BBN are indicative of this trend. Accordingly, the
          Company expects that it will experience increased competition
          from the traditional telecommunications carriers. Many of these
          telecommunications carriers, in addition to their substantially
          greater network coverage, market presence, and financial,
          technical and personnel resources, also have large existing
          commercial customer bases.

             Cable Companies, Direct Broadcast Satellite and Wireless
          Communications Companies. Many of the major cable companies have
          announced that they are exploring the possibility of offering
          Internet connectivity, relying on the viability of cable modems
          and economical upgrades to their networks. Continental
          Cablevision, Inc. and Tele-Communications, Inc. ("TCI") have
          recently announced trials to provide Internet cable service to
          their residential customers in select areas. However, the cable
          companies are faced with large-scale upgrades of their existing
          plant equipment and infrastructure in order to support
          connections to the Internet backbone via high-speed cable access
          devices. Additionally, their current subscriber base and market
          focus is residential which requires that they partner with
          business-focused providers or undergo massive sales and marketing
          and network development efforts in order to target the business
          sector. Several announcements also have recently been made by
          other alternative service companies approaching the Internet
          connectivity market with various wireless terrestrial and
          satellite-based service technologies. These include Hughes
          Network Systems' announcement that it will provide high-speed
          data through direct broadcast satellite technology; CAI Wireless
          Systems Inc.'s ("CAI Wireless") announcement of an MMDS wireless
          cable operator launching data services via 2.5 to 2.7 GHz and
          high-speed wireless modem technology; and WinStar Communications,
          a 38 GHz radio company that wholesales its network capacity to
          other carriers and now offers high-speed Internet access to
          business customers.

             On-line Service Providers. The dominant on-line service
          providers, including Microsoft Network, America Online,
          Incorporated ("America Online"), Compuserve, Inc. ("Compuserve")
          and Prodigy, Inc., ("Prodigy") have all entered the Internet


                                      -17-
     


          access business by engineering their current proprietary networks
          to include Internet access capabilities. The Company competes to
          a lesser extent with these service providers, which currently are
          primarily focused on the consumer marketplace and offer their own
          content, including chat rooms, news updates, searchable reference
          databases, special interest groups and shopping. While Compuserve
          recently announced it will also target Internet connectivity for
          the small to medium-sized business market, this will require a
          significant transition from a consumer market focus to a business
          market focus.

             The Company believes that its ability to attract business
          customers and to market value-added services are keys to its
          future success. However, there can be no assurance that its
          competitors will not introduce similar pricing plans at
          comparable or more attractive prices in the future or that the
          Company will not be required to reduce its prices to match
          competition. Recently, many competitive ISPs have shifted their
          focus from individual customers to business customers. Moreover,
          there can be no assurance that more of the Company's competitors
          will not shift their focus to attracting business customers,
          resulting in even more competition for the Company. There can be
          no assurance that NETCOM will be able to offset the effects of
          any such competition or resulting price reductions through an
          increase in the number of its subscribers, higher revenue from
          enhanced services, cost reductions or otherwise. Increased
          competition could result in erosion of NETCOM's market share and
          adversely affect NETCOM's operating results.

             Increased competition has resulted and could continue to
          result in significant reductions in the average selling price of
          NETCOM's services. In addition, NETCOM expects to see increased
          pressure to obtain and retain additional subscribers that could
          result in increased sales and marketing expenses and related
          subscriber acquisition costs, which could materially adversely
          affect NETCOM's rate of customer churn and operating results.
          Certain of the Company's on-line competitors, including America
          Online, the Microsoft Network, Compuserve and Prodigy, have
          introduced unlimited access to the Internet and their proprietary
          content at flat rates as low as $9.95 per month. Certain of the
          RBOCs have also introduced competitive flat-rate pricing for
          unlimited access (without a set-up fee for at least some period
          of time). As a result, competition for active users of Internet
          services has intensified. There can be no assurance that the
          Company's competitors will not introduce more attractive prices
          in the future or that the Company will not be required to reduce
          its prices to match competition. There can be no assurance that
          NETCOM will be able to offset the effects of any such competition
          or resulting price reductions through an increase in the number
          of its subscribers, higher revenue from enhanced services, cost
          reductions or otherwise. Increased competition could result in
          erosion of the Company's market share and adversely affect the
          Company's operating results and ability to make payments on the
          New Notes. There can be no assurance that the Company will have
          financial resources, technical resources, technical expertise or
          marketing and support capabilities to continue to compete
          successfully.

          HOLDING COMPANY STRUCTURE; PRIORITY OF CREDITORS

             The Company is a holding company. The principal assets of the
          Company consist of common stock of NETCOM and will consist of
          common stock of other subsidiaries upon any future acquisitions.
          The Company must rely upon dividends and other payments from its
          subsidiaries to generate the funds necessary to meet its
          obligations, including the payment of principal of and interest
          on the New Notes. The subsidiaries, however, are legally distinct
          from the Company and have no obligation, contingent or otherwise,
          to pay amounts due pursuant to the New Notes or to make funds
          available for such payment. The Company's subsidiaries will not
          guarantee the New Notes. The ability of the Company's
          subsidiaries to make such payments to the Company will be subject
          to, among other things, the availability of funds, the terms of
          such subsidiaries' indebtedness and applicable state laws. The
          Indenture will permit the Company's subsidiaries to incur
          substantial amounts of additional indebtedness and will allow
          that indebtedness to be secured with the assets of the
          subsidiaries (which constitute substantially all of the Company's
          consolidated assets). In addition, lenders to subsidiaries may
          impose restrictions on those subsidiaries' ability to make
          payments to the Company. 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 New Notes. Accordingly, the New Notes will be
          effectively subordinated to the liabilities (including trade
          payables) of the subsidiaries of the Company. At December 31,


                                      -18-
     


          1997, on a pro forma basis giving effect to the Private Offering
          and the acquisition of NETCOM, the subsidiaries of the Company
          would have had approximately $34.5 million of liabilities
          (excluding intercompany payables), including approximately $6.0
          million of indebtedness, consisting solely of capitalized lease
          obligations. In addition, the Indenture will permit the Company
          and its Restricted Subsidiaries to make substantial investments
          in entities they do not control, including an unlimited amount of
          investments in CSW/ICG ChoiceCom, L.P. ("ChoiceCom"), a new
          telecommunications company in Texas that has a strategic
          relationship with ICG.

             The New Notes will be senior, unsecured indebtedness of the
          Company. At December 31, 1997, on a pro forma basis giving effect
          to the acquisition of NETCOM and the Private Offering, the
          Company would have had, on a consolidated basis, an aggregate of
          approximately $306.6 million of secured indebtedness, including
          capitalized lease obligations. 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
          New Notes, notwithstanding the existence of any event of default
          with respect to the New Notes. The Indenture also permits the
          Company and its subsidiaries to incur substantial amounts of
          additional secured indebtedness and to grant additional liens.
          See "Description of the New Notes -- Covenants." In the event of
          bankruptcy, liquidation or reorganization of the Company, holders
          of secured indebtedness will have a claim, prior to the claim of
          the holders of the New Notes, on the assets of the Company
          securing such indebtedness. In addition, to the extent that the
          value of such collateral is insufficient to satisfy such secured
          indebtedness, holders of amounts remaining outstanding on such
          secured indebtedness (as well as other unsubordinated creditors
          of the Company) would be entitled to share pari passu with the
          holders of New Notes with respect to any other assets of the
          Company. Assets remaining after satisfaction of the claims of
          holders of secured indebtedness may not be sufficient to pay
          amounts due or any or all of the New Notes then outstanding.

          RISKS RELATED TO CHANGE IN CUSTOMER FOCUS TO ATTRACT BUSINESS
          CUSTOMERS

             In January 1997, NETCOM announced plans to migrate its
          customer focus away from high volume, low margin consumer
          customers to higher margin products for small and medium-sized
          business customers. Although NETCOM has increased the number of
          its direct access business customers and its revenue per customer
          in 1997, and expects to invest significant resources to continue
          to increase the number of direct access business customers and
          its revenue per customer, there can be no assurance that the
          Company will be able to continue to increase the number of its
          direct access business customers or its revenue per customer in
          the future. Furthermore, many of the Company's competitors have
          shifted their focus to pursue business customers. There can be no
          assurance that more competition for business accounts will not
          lead to a significant slowdown in the growth of, or a decrease
          in, the Company's direct access business customers or its revenue
          per customer, and such slowdown or decrease could have a material
          adverse effect on the Company's business, financial condition and
          results of operations and its ability to make payments on the New
          Notes.

          DEPENDENCE UPON NEW AND ENHANCED SERVICES

             NETCOM has recently introduced new enhanced business
          connectivity solutions services, including NETCOMplete packages
          offering customers anti-virus file conversion, support, E-mail
          access, data storage, Automatic Reconnect and other premium,
          higher-priced services. The failure of these services to gain
          market acceptance in a timely manner or at all could have a
          material adverse effect on the business, financial condition and
          results of operations of the Company and its ability to make
          payments on the New Notes. Introduction by NETCOM of new or
          enhanced services with reliability, quality or compatibility
          problems could significantly delay or hinder market acceptance of
          all of NETCOM's services, which would adversely affect the
          Company's ability to attract new customers and subscribers. The
          Company's services may contain undetected errors or defects when
          first introduced or when enhancements are introduced. There can
          be no assurance that, despite testing by NETCOM and its
          customers, errors will not be found in new services after
          commencement of commercial deployment, resulting in additional
          development costs, loss of, or delays in, market acceptance,
          diversion of technical resources and loss of subscribers. Any


                                      -19-
     


          such event would have a material adverse effect on the Company's
          business, financial condition and results of operations and its
          ability to make payments on the New Notes.

          RISKS RELATED TO INTERNET TELEPHONE BUSINESS AND HIGH-SPEED DATA
          TRANSMISSION SERVICES BUSINESS

             In March 1998, ICG and NETCOM announced their plans to offer
          long distance services via IP technology.  Furthermore, ICG and
          NETCOM plan to offer high-speed data transmission services via
          DSL technology to all business and end user customers within
          ICG's existing regional clusters by the end of fiscal 1998.  ICG
          and NETCOM anticipate expending significant capital and operating
          costs in connection with providing such services and will have to
          address issues concerning commercial use of such services,
          including security, reliability, ease of access and quality of
          service.  For example, IP technology may cause poor quality voice
          transmission and DSL technology may cause interference with and
          be interfered by other signals present in ILEC's copper
          transmission facilities.  There can be no assurance that ICG and
          NETCOM will be able to successfully resolve such issues and
          market, sell and deliver these services.  Because long distance
          services using IP technology and high-speed data transmission
          services using DSL technology are relatively new and evolving, it
          is difficult to predict their future  growth and size.  If the
          markets for such services to be offered by ICG and the Company,
          through NETCOM, fail to grow or grow more slowly than
          anticipated, such events could have a material adverse effect on
          the Company and its ability to make payments on the New Notes.

             Although the Company is not currently subject to direct
          regulation by the FCC or any other governmental agency, it is
          possible that the Company and other ISPs could become subject to
          regulation by the FCC or another regulatory agency as a provider
          of basic telecommunications services.  The FCC is currently
          considering whether ISPs should be required to pay access charges
          to local telephone companies for each minute that dial-access
          users spend connected to ISPs through telephone company switches. 
          In addition, some telephone companies are seeking relief through
          state regulatory agencies.  The FCC may also decide that ISPs
          should contribute to the federal Universal Service Fund.  Such
          requirements, if adopted at either the federal or the state
          level, would have a material adverse effect on ICG and NETCOM's
          abilities to implement their long distance services via IP
          technology and high-speed data transmission services via DSL
          technology, or if implemented, to profitably sell such services,
          and the Company's ability to make payments on the New Notes.  See
          "--Regulation."

          POTENTIAL LIABILITY FOR CONTENT

             The Communications Decency Act (the "Act"), which was passed
          as part of the Federal Telecommunications Act of 1996, imposed
          criminal penalties on anyone who distributes obscene, lascivious
          or indecent communications on the Internet. As enacted, the Act
          imposed fines on any entity that (i) by means of a
          telecommunications device, knowingly sends indecent or obscene
          material to a minor; (ii) by means of an interactive computer
          service, sends or displays indecent material to a minor; or (iii)
          permits any telecommunications facility under such entity's
          control to be used for the foregoing purposes. That provision, as
          applied to indecent material, was declared unconstitutional in
          June 1997 by the United States Supreme Court. While the Clinton
          Administration has announced that it will not seek passage of
          similar legislation to replace this provision, action by Congress
          in this area remains possible. Prior to the enactment of the Act,
          a federal district court held that an ISP could be found liable
          for defamation on the grounds that it exercised active editorial
          control over postings to its service. The Act contains a
          provision which, one court has held, shields ISPs from such
          liability for material posted to the Internet by their
          subscribers or other third parties.

             The applicability to the Internet of existing laws governing
          issues such as property ownership, libel and privacy is
          uncertain. For example, in 1996 NETCOM settled a lawsuit alleging
          copyright infringement against NETCOM relating to electronic
          messages posted by an unrelated individual to a bulletin board
          service operated by one of NETCOM's customers. New legislation or
          regulation with respect to content could have a material adverse
          effect on the Company's business, results of operations,
          financial condition and ability to make payments on the New
          Notes.


                                      -20-
     


             As the law in this area develops, the potential that liability
          might be imposed on the Company for information carried on or
          disseminated through its network could require the Company to
          implement measures to comply with applicable law and reduce its
          exposure to such liability, which could require the expenditure
          of substantial resources or the discontinuation or modification
          of certain service offerings. Any costs incurred as a result of
          such expenditures or in contesting any such asserted claims, the
          consequent imposition of liability, or any adverse publicity
          resulting from any of the foregoing, could have a material
          adverse affect on the Company and its ability to make payments on
          the New Notes.

          DEPENDENCE ON BILLING, CUSTOMER SERVICE AND INFORMATION SYSTEMS

             Sophisticated information and processing systems are vital to
          the Company's growth and its ability to monitor costs, bill
          customers, provision customer orders and achieve operating
          efficiencies.

             NETCOM's billing and information systems are primarily
          products and services provided by third party vendors. These
          systems have generally met NETCOM's historical needs, primarily
          due to a relatively low volume of customer accounts requiring
          complex billing requests. However, information systems are vital
          as NETCOM expects to offer numerous products and services at
          varying prices. Additionally, NETCOM expects the amount of
          customers with more complex billing requests in general to
          increase. NETCOM is currently evaluating a billing platform based
          upon an information system purchased from a third party vendor
          with internal enhancements to meet NETCOM's needs. The failure of
          (i) the Company's vendors to deliver proposed products and
          services in a timely and effective manner, (ii) the Company to
          adequately identify all of its information and processing needs
          or (iii) the Company to upgrade systems as necessary, could have
          a material adverse impact on the ability of NETCOM to reach its
          objectives, and on the Company's financial condition and results
          of operations and ability to make payments on the New Notes.

             While the Company believes that its software applications are
          year 2000 compliant, there can be no assurance until the year
          2000 occurs that all systems will then function adequately.
          Further, if the software applications of local exchange carriers,
          long distance carriers or others on whose services the Company
          depends are not year 2000 compliant, it could have a material
          adverse effect on the Company's financial condition and results
          of operations and ability to make payments on the New Notes.

          KEY PERSONNEL

             The efforts of a small number of key management and operating
          personnel will largely determine the Company's success. The
          success of the Company also depends in part upon its ability to
          hire and retain highly skilled and qualified operating,
          marketing, financial and technical personnel. The competition for
          qualified personnel in the telecommunications and Internet access
          services industries is intense and, accordingly, there can be no
          assurance that the Company will be able to hire or retain
          necessary personnel. The competition for qualified computer
          programmers and engineers is particularly intense in the "Silicon
          Valley" area of California, where NETCOM's operations are based.
          The Company may be compelled to offer substantially increased
          compensation and benefits packages to attract and retain computer
          programmers and engineers. The loss of certain key personnel or
          the failure of the Company to attract and retain qualified
          personnel could adversely affect the Company and its ability to
          make payments on the New Notes.

          RAPID TECHNOLOGICAL CHANGE

             NETCOM's success is highly dependent upon its ability to
          develop new services and software that meet changing customer
          requirements. The market for NETCOM's services is characterized
          by rapidly changing technology, evolving industry standards,
          emerging competition and frequent new software, service and
          product introductions. There can be no assurance that NETCOM can
          successfully identify new service opportunities and develop and
          bring new services and software to market in a timely manner, or


                                      -21-
     


          that services, software or technologies developed by others will
          not render NETCOM's services, software or technologies
          noncompetitive or obsolete. NETCOM is also at risk of fundamental
          changes in the way Internet access services are delivered. New
          industry standards have the potential to replace or provide
          lower-cost alternatives to the Company's existing services. The
          adoption of such new industry standards could render the
          Company's existing services obsolete and unmarketable or require
          reduction in the fees charged therefor. For example, the
          Company's services currently rely on the widespread commercial
          use of Transmission Control Protocol/ Internet Protocol
          ("TCP/IP"). Alternative open and proprietary standards that
          compete with TCP/IP, including proprietary protocols developed by
          International Business Machines Corporation and Novell, Inc. have
          been or are being developed. The widespread acceptance of these
          or other protocols could have a material adverse effect on the
          Company.

             The Company's business is also sensitive to fundamental
          changes in the method of Internet access delivery. Currently, the
          Internet is accessed primarily via computers connected by
          telephone lines. A number of alternative methods for users to
          connect to the Internet, including cable modems, satellites and
          other wired and wireless telecommunications technologies,
          currently are under development. As the Internet becomes
          accessible through these technologies, or as user requirements as
          to access methods change, the Company will have to develop new
          technology or modify its existing technology. The Company's
          pursuit of these technological advances may require substantial
          time and expense, and there can be no assurance that the Company
          will succeed in adapting its Internet access business to
          alternate access methods. Any failure on the part of the Company
          to identify, adopt and use new technologies effectively, to
          develop its technological capabilities or to develop new services
          or enhance existing services in a timely and cost-effective
          manner could have a material adverse effect on the Company and
          its ability to make payments on the New Notes.

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

             As the industry evolves, required technological advances by
          NETCOM could include compression, full-motion video, and
          integration of video, voice, data and graphics. NETCOM's pursuit
          of these technological advances may require substantial time and
          expense, and there can be no assurance that NETCOM will succeed
          in adapting its Internet service business to alternate access
          devices and conduits.

          DEPENDENCE ON THE INTERNET; UNCERTAIN ADOPTION OF INTERNET AS A
          MEDIUM OF COMMERCE AND COMMUNICATIONS

             The Company's products and services are targeted toward users
          of the Internet, which has experienced rapid growth. As is
          typical in the case of a new and rapidly evolving industry
          characterized by rapidly changing technology, evolving industry
          standards and frequent new product and service introductions,
          demand and market acceptance for recently introduced products and
          services are subject to a high level of uncertainty. In addition,
          critical issues concerning the commercial use of the Internet
          remain unresolved and may impact the growth of Internet use,
          especially in the business market targeted by the Company.
          Despite growing interest in the many commercial uses of the
          Internet, many businesses have been deterred from purchasing
          Internet access services for a number of reasons, including,
          among others, inconsistent quality of service, lack of
          availability of cost-effective, high-speed options, a limited
          number of local access points for corporate users, inability to
          integrate business applications on the Internet, the need to deal
          with multiple and frequently incompatible vendors, inadequate
          protection of the confidentiality of stored data and information
          moving across the Internet, and a lack of tools to simplify
          Internet access and use. In particular, numerous published
          reports have indicated that a perceived lack of security of
          commercial data, such as credit card numbers, has significantly
          impeded commercial exploitation of the Internet to date, and
          there can be no assurance that encryption or other technologies
          will be developed that satisfactorily address these security
          concerns. Published reports have also indicated that capacity
          constraints caused by growth in the use of the Internet may,
          unless resolved, impede further development of the Internet to
          the extent that users experience delays, transmission errors and
          other difficulties. Further, the adoption of the Internet for


                                      -22-
     


          commerce and communications, particularly by those individuals
          and enterprises that have historically relied upon alternative
          means of commerce and communication, generally requires the
          understanding and acceptance of a new way of conducting business
          and exchanging information. In particular, enterprises that have
          already invested substantial resources in other means of
          conducting commerce and exchanging information may be
          particularly reluctant or slow to adopt a new strategy that may
          make their existing personnel and infrastructure obsolete. The
          failure of the market for business-related Internet solutions to
          continue to develop would adversely impact the Company's
          business, financial condition and results of operations and
          ability to make payments on the New Notes.

             NETCOM's current customer base consists primarily of
          individuals and small and medium-sized businesses, and the
          Company's success will depend in part upon the continuing
          development and expansion of the Internet and the market for
          Internet access. While Internet access may afford businesses with
          a convenient and inexpensive resource of business-related
          information, Internet access also enables the end user, including
          an employee of a small or medium-sized business, to access a wide
          variety of non-business related information and/or recreational
          material that may distract the end user from his or her work-
          related responsibilities. Therefore, there may be a risk that
          such abuse of Internet access by employees resulting in decreased
          productivity of these employees could cause business demand for
          Internet services to decrease. There is also the risk that the
          perceived potential for abuse of Internet access privileges by
          employees could prevent otherwise interested businesses from
          subscribing to, or expanding their subscriptions with, NETCOM,
          which could have a material adverse effect on the Company's
          business, operating results and financial condition and ability
          to make payments on the New Notes.

          DEPENDENCE ON DISTRIBUTION AND MARKETING RELATIONSHIPS

             NETCOM believes that its success in penetrating markets for
          its Internet connectivity services depends in large part on its
          ability to maintain and develop additional relationships with
          leading companies that market computer products and to cultivate
          alternative relationships if distribution channels change. NETCOM
          has entered into original equipment manufacturer ("OEM")
          agreements, distribution agreements, and other agreements with a
          number of such companies. In addition, the Company will enter
          into agreements relating to the marketing of NETCOM's products
          and services by ICG's sales force. The termination or
          renegotiation of certain of these relationships could have a
          material adverse effect on NETCOM. All of these agreements are
          nonexclusive, and many of the companies with which NETCOM has
          agreements also have similar agreements with NETCOM's
          competitors. In addition, there can be no assurance that NETCOM's
          distributors and OEMs with which NETCOM has relationships, many
          of which have significantly greater financial and marketing
          resources than NETCOM, will not develop and market products in
          competition with NETCOM in the future, discontinue their
          relationships with NETCOM or form additional competing
          arrangements with NETCOM's competitors.

          RISKS RELATED TO INTERNATIONAL VENTURES

             NETCOM began offering Internet services in the United Kingdom
          and Canada through its international subsidiaries in 1995 and may
          seek to acquire additional businesses outside of the United
          States. There can be no assurance that the Company will be able
          to successfully market, sell and deliver its services in the
          United Kingdom, Canada or other international markets that it may
          decide to enter in the future. In addition, there are certain
          significant risks inherent in doing business on an international
          level, such as laws governing content that differ greatly from
          those in the United States, unexpected changes in regulatory
          requirements, political risks, export restrictions, tariffs and
          other trade barriers, fluctuations in currency exchange rates,
          and issues regarding intellectual property and potentially
          adverse tax consequences, any or all of which could impact the
          Company's international operations. NETCOM's EBITDA losses for
          its international operations for fiscal 1997 were $13.4 million.

          DEPENDENCE ON SUPPLIERS

             NETCOM relies on other companies to provide data
          communications capacity via leased telecommunications lines. If
          NETCOM's suppliers are unable or unwilling to provide or expand


                                      -23-
     


          its current levels of service to NETCOM in the future, NETCOM's
          operations would be materially adversely affected. Although
          leased telecommunications lines are available from several
          alternative suppliers, including ICG, there can be no assurance
          that NETCOM could obtain substitute services from other providers
          at reasonable or comparable prices or in a timely fashion. NETCOM
          is also subject to risks relating to potential disruptions in its
          suppliers' services, and there are no assurances that such
          interruptions will not occur in the future. Service interruptions
          can produce substantial customer dissatisfaction and lead to
          higher rates of customer churn.

             NETCOM is also dependent on certain third party suppliers of
          software and hardware components. Although NETCOM attempts to
          maintain a minimum of two vendors for each required product,
          certain components used by NETCOM in providing its networking
          services are currently acquired from only one source, including
          high performance routers manufactured by Cisco Systems, Inc.
          ("Cisco"), modems manufactured by U.S. Robotics Corporation
          ("U.S. Robotics"), switches manufactured by Cascade
          Communications, Inc. ("Cascade") and servers from Sun
          Microsystems, Inc. ("Sun Microsystems"). NETCOM has also from
          time to time experienced delays in the receipt of certain
          software and hardware components. A failure by a supplier to
          deliver quality products on a timely basis, or the inability to
          develop alternative sources if and as required, could result in
          delays that could materially adversely affect the Company's
          business, operating results and financial condition and ability
          to make payments on the New Notes.

          DEPENDENCE ON NETWORK INFRASTRUCTURE; RISK OF SYSTEM FAILURE;
          SECURITY RISKS

             The future success of NETCOM's business will depend upon the
          capacity, reliability and security of its network infrastructure.
          NETCOM has in the past experienced network problems and network
          slowdowns due to limited server capacity in NETCOM's NOCs. NETCOM
          is currently implementing systems and processes in order to
          address these problems and improve NETCOM's service generally.
          NETCOM must continue to expand and adapt its network
          infrastructure as the amount of information NETCOM wishes to
          transfer increases and to meet changing customer requirements.
          The expansion and adaptation of NETCOM's network infrastructure
          will require substantial financial, operational and management
          resources. There can be no assurance that NETCOM will be able to
          expand or adapt its network infrastructure to meet additional
          demand or its changing customer requirements on a timely basis,
          at a commercially reasonable cost, or at all, or that NETCOM will
          be able to deploy successfully the contemplated network
          expansion. Any failure of NETCOM to expand its network
          infrastructure on a timely basis or to adapt it to changing
          customer requirements or evolving industry standards could have a
          material adverse effect on the Company's business, operating
          results and financial condition and ability to make payments on
          the New Notes.

             NETCOM's operations are dependent on its ability to protect
          its computer equipment against damage from fire, earthquakes,
          power loss, telecommunications failures and similar events. A
          significant portion of NETCOM's computer equipment is located at
          its NOCs and NETCOM is subject to significant risk to NETCOM's
          operations from a natural disaster or other unanticipated event
          at one of these sites. Any damage or failure that causes
          interruptions in NETCOM's operations could have a material
          adverse effect on the Company's business, operating results,
          financial condition and ability to make payments on the New
          Notes.

             Despite the implementation of security measures, NETCOM's
          infrastructure is also vulnerable to computer viruses or similar
          disruptive problems caused by its customers or other Internet
          users. Computer viruses or problems caused by third parties could
          lead to interruptions, delays or cessation in service to NETCOM's
          customers. Furthermore, inappropriate use of the Internet by
          third parties could also potentially jeopardize the security of
          confidential information stored in the computer systems of
          NETCOM's customers and could also cause dissemination of
          unwanted, inappropriate or objectionable materials to NETCOM's
          customers, any of which may deter certain persons from
          subscribing to NETCOM's services.

             Any network malfunction or security breach could cause
          commercial transactions to be delayed, not completed or completed
          with compromised security. Although the Company intends to
          continue to implement and maintain security measures, such


                                      -24-
     


          measures have been circumvented in the past and may be defeated
          in the future. Alleviating problems caused by computer viruses or
          other inappropriate uses or security breaches may cause
          interruptions, delays or cessation in service to the Company's
          subscribers, which could have a material adverse effect on the
          Company. In addition, there can be no assurance that subscribers
          or others will not assert claims of liability against the Company
          as a result of these events. Further, until more comprehensive
          security technologies are developed and implemented, security and
          privacy concerns of existing and potential subscribers may
          inhibit the growth of the Internet access services industry in
          general and of the Company's user base in particular.

          REGULATION

             The Company provides Internet access services in part through
          data transmissions over public telephone lines. These
          transmissions are governed by regulatory policies establishing
          charges and terms for wire-line communications. Although the
          Company is not currently subject to direct regulation by the FCC
          or any other governmental agency (other than regulations
          applicable to businesses generally), due to the increasingly
          widespread use of the Internet, it is possible that additional
          laws and regulations may be adopted with respect to the Internet,
          covering issues such as content, user privacy, pricing, libel,
          intellectual property protection and infringement, and technology
          export and other controls. It also is possible that the Company
          could become subject to regulation by the FCC or another
          regulatory agency as a provider of basic telecommunications
          services. The FCC is currently reviewing its regulatory positions
          to impose common carrier regulation on the network transport and
          communications facilities aspects of an enhanced or information
          service package. Such changes in the regulatory structure and
          environment affecting the Internet access market, including
          regulatory changes that directly or indirectly affect
          telecommunications costs or increase the likelihood of
          competition from the RBOCs or other telecommunications companies,
          could have an adverse effect on the Company's business. For
          example, the FCC is considering whether ISPs should be required
          to pay access charges to local telephone companies for each
          minute that dial-access users spend connected to ISPs through
          telephone company switches. In addition, some telephone companies
          are seeking similar relief through state regulatory agencies and
          have raised this issue before the Eighth Circuit Court of
          Appeals.  The FCC may also decide that ISPs should pay access
          charges and/or contribute to the federal Universal Service Fund. 
          However, in a recent Report on Universal Service sent to Congress
          by the FCC on April 10, 1998, the FCC reaffirmed its view that as
          a general matter ISPs are information services providers and not
          telecommunications carriers, and reiterated that information
          services providers are not subject to universal service
          obligations, access charges or rate regulation.  Additionally,
          the Report declines to make any definitive pronouncements on
          whether various new services, such as certain forms of Internet
          telephone services, should be classified as information services
          or telecommunications services.  Instead, the FCC deferred
          consideration of that issue to future proceedings.  If adopted at
          either the federal or state level, new requirements that ISPs pay
          access charges and/or contribute to the Universal Service Fund
          could have a material adverse effect on the Company and its
          ability to make payments on the New Notes. The Company cannot
          predict the impact, if any, that future regulation or regulatory
          changes may have on its business.

             Certain states have deemed the provision of Internet services
          to be taxable and, in such states, NETCOM collects such taxes
          from its customers. Other states have not yet announced a policy
          in this regard or have affirmatively decided that such services
          are not taxable. If such states retroactively subject the
          provision of Internet services to sales tax or if customers are
          unwilling to pay sales tax that may be assessed in the future,
          such events could have a material adverse effect on the Company
          and its ability to make payments on the New Notes.

          RISKS RELATING TO CUSTOMER CHURN

             ISPs are subject to substantial customer "churn," the term
          used for customer turnover through cancellations. High churn
          rates may indicate customer dissatisfaction with the ISP and may
          cause the ISP to incur substantial costs to retain existing
          customers and attract new customers. Any substantial increase in
          NETCOM's churn rate could have a material adverse effect on the
          Company's business, operating results, financial condition and
          its ability to make payments on the New Notes.


                                      -25-
     


          CONTROL BY ICG

             ICG owns all of the Company's issued and outstanding capital
          stock and thus has complete voting control over the corporate
          governance of the Company, including the election of the
          Company's Board of Directors and other corporate actions
          requiring stockholder approval. Certain decisions concerning the
          operations or financial structure of the Company may present
          conflicts of interest between ICG and the holders of the New
          Notes. For example, if the Company encounters financial
          difficulties or is unable to pay its debts as they mature, the
          interests of ICG might conflict with those of the holders of the
          New Notes. In addition, ICG may have an interest is pursuing
          certain acquisitions, divestitures, financings or other
          transactions that, in its judgment, could enhance its equity
          interest in the Company, even though such transactions might
          involve risks to the holders of the New Notes. See "Sole
          Stockholder of the Company."

          LIMITED INTELLECTUAL PROPERTY PROTECTION

             NETCOM relies on a combination of copyright and trademark
          laws, trade secrets, software security measures, license
          agreements and nondisclosure agreements to protect its
          proprietary technology and software products. NETCOM currently
          has no domestic or foreign patents or patent applications
          pending. Despite NETCOM's precautions, it may be possible for
          unauthorized third parties to lawfully or unlawfully copy aspects
          of, or otherwise obtain and use, NETCOM's software products and
          technology. In addition, NETCOM cannot be certain that others
          will not develop substantially equivalent or superseding
          proprietary technology, thereby substantially reducing the value
          of NETCOM's proprietary rights.

             From time to time NETCOM has received notices claiming that it
          is infringing the proprietary rights of third parties, and there
          can be no assurance that NETCOM will not become the subject of
          infringement claims or legal proceedings by third parties with
          respect to current or future products. Any such claims could be
          time consuming, result in costly litigation, cause product
          shipment delays or lead NETCOM to enter into royalty or licensing
          agreements rather than disputing the merits of such claims.
          Moreover, an adverse outcome in such proceedings could subject
          NETCOM to significant liabilities to third parties, require
          expenditure of significant resources to develop non-infringing
          technology, require disputed rights to be licensed from others or
          require NETCOM to cease the marketing or use of certain products,
          any of which could have a material adverse effect on the
          Company's business, operating results and financial condition.

          RISKS RELATED TO CSW/CHOICECOM OPTIONS

             Pursuant to agreements entered into with affiliates of Central
          and South West Corporation ("CSW") in December 1996, as
          subsequently revised, relating to ChoiceCom, prior to offering
          ISP services in the states of Texas, Oklahoma, Louisiana and
          Arkansas, ICG is obligated to offer CSW the right to purchase up
          to a 49% interest in the business opportunity providing such
          services. Consequently, ICG has offered CSW an option to purchase
          up to 49% of that portion of the business of NETCOM that provides
          such services in such four-state area (the "ISP Opportunity") at
          a price based on the costs and expenses incurred by ICG to
          acquire such ISP Opportunity. The Company does not know whether
          CSW will exercise this option. If CSW does not exercise this
          option, at such time, if ever, that ICG exercises the option it
          currently holds to acquire a 50% interest in ChoiceCom, ChoiceCom
          will then effectively have the right to acquire 100% of the ISP
          Opportunity from ICG at a price equal to ICG's costs and expenses
          (including an implied interest rate) incurred with respect to
          such ISP Opportunity. As a result, ICG is required to maintain
          separate books and records for the ISP Opportunity, and
          transactions between the ISP Opportunity and NETCOM's other
          operations will be carried out on an arm's length basis.
          Additionally, options on substantially the same terms will be
          available to CSW and ChoiceCom with respect to all
          telecommunications business opportunities in such four-state
          area.


                                      -26-
     


          CERTAIN FINANCIAL AND OPERATING RESTRICTIONS

             The Indenture and other indebtedness of the Company impose
          operating and financial restrictions on the Company. Such
          restrictions affect, and in certain cases significantly limit or
          prohibit, among other things, 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. A default under such indebtedness could result in an
          acceleration of the Notes, in which case the holders of the New
          Notes may not be paid in full.

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

             The New Notes will be issued at a substantial discount from
          their principal amount. Although cash interest will not accrue on
          the New Notes prior to February 15, 2003, and there will be no
          periodic payments of cash interest on the New Notes prior to
          August 15, 2003, original issue discount (the difference between
          the stated redemption price at maturity and the issue price of
          the New Notes) will accrue from the issue date of the New Notes.
          Original issue discount will be includible as interest income
          periodically (including for periods ending prior to February 15,
          2003) in a U.S. Holder's gross income for U.S. federal income tax
          purposes in advance of receipt of the cash payments to which the
          income is attributable. See "Certain United States Federal Income
          Tax Considerations" for a more detailed discussion of the federal
          income tax consequences to the Holders of a New Note regarding
          the purchase, ownership and disposition of the Notes.

             If a bankruptcy case is commenced by or against the Company
          under the U.S. Bankruptcy Code after the issuance of the New
          Notes, the claim of a holder of a New Note with respect to the
          principal amount thereof may be limited to an amount equal to the
          sum of (i) the initial offering price and (ii) that portion of
          the original issue discount that is not deemed to constitute
          "unmatured interest" for purposes of the U.S. Bankruptcy Code.
          Any original issue discount that was not amortized as of any such
          bankruptcy filing would constitute "unmatured interest."

          LACK OF PUBLIC MARKET

             The New Notes are a new issue of securities for which there is
          currently no active trading market. If any New Notes are traded
          after their initial issuance, they 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, performance of, and prospects for the Company.  There
          can be no assurance of an active trading market for any of the
          New Notes.

                               SELECTED FINANCIAL DATA

             The Company is a newly formed Delaware corporation and,
          accordingly, no financial statements for the Company have been
          included herein. NETCOM is a wholly owned subsidiary of the
          Company, acquired in a pooling-of-interests transaction with ICG.

             The following table sets forth selected financial and other
          operating data of NETCOM, the predecessor to the Company, for
          each fiscal year in the five-year period ended December 31, 1997.
          Such data have been derived from, and should be read in
          conjunction with, NETCOM's audited consolidated financial
          statements and notes thereto included elsewhere in this
          Prospectus for each of the fiscal years in the three-year period
          ended December 31, 1997. NETCOM's development and expansion
          activities, including acquisitions, during the periods shown
          below materially affect the comparability of this data from one
          period to another.

          (1)  Results for fiscal 1995 include five months of results of
               Professional Internet Consulting, Inc., which was acquired
               by NETCOM in August 1995.
          (2)  Giving pro forma effect to the receipt of the net proceeds
               from the Private Offering and interest expense, net on
               $300.6 million gross proceeds of Notes, without giving any
               effect to any increased interest income on available cash,
               as if such events had occurred on January 1, 1997, interest
               expense, net would have been $26.6 million for fiscal 1997.
          (3)  Capital expenditures include assets acquired under capital
               leases. 
          (4)  EBITDA is provided because it is a measure commonly used in
               the Internet and telecommunications industries. EBITDA is
               presented to enhance the understanding of NETCOM's operating
               results and is not intended to represent cash flows or
               results of operations in accordance with GAAP for the
               periods indicated. EBITDA is not a measurement under GAAP
               and is not necessarily comparable with similarly titled
               measures of other companies. Net cash flows from operating,
               investing and financing activities as determined using GAAP
               are also presented in Other Data.
          (5)  Earnings were insufficient to cover fixed charges in fiscal
               1994, 1995, 1996 and 1997 by $.1 million, $14.0 million,
               $44.2 million and $33.1 million, respectively. On a pro
               forma basis giving effect to the Private Offering as if it
               had occurred on January 1, 1997 and without giving effect to
               any increased interest income on additional available cash,
               earnings would have been insufficient to cover fixed charges
               by $63.1 million for fiscal 1997. Earnings consist of income
               (loss) before provision for income taxes plus fixed charges.
               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 rental expense the Company believes to be
               representative of interest (i.e., one-third of rental
               expense).

             MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                              AND RESULTS OF OPERATIONS

               The following discussion includes certain forward-looking
          statements which are affected by important factors including, but
          not limited to, the Company's lack of operating history,
          historical operating losses of NETCOM and lack of credit support
          from ICG that could cause actual results to differ materially
          from the forward-looking statements. See "Risk Factors."

          OVERVIEW

               The Company was formed in January 1998 and has conducted no
          material operations to date other than the acquisition and
          operations of NETCOM. See "The Company." Therefore, the following
          discussion is a discussion and analysis of the results of
          operations and financial condition of NETCOM, the predecessor
          business to the Company. The Company's results of operations and
          financial condition will change as it consummates acquisitions
          and as the operations of ICG Equipment becomes more significant.

               NETCOM is a leading provider of high quality Internet
          solutions to individual and small and medium-sized businesses in
          the United States and also provides the same high quality
          Internet solutions in Canada and the United Kingdom. NETCOM
          offers a broad spectrum of Internet solutions designed to enhance
          customer productivity through the integration and application of
          technologies by providing a comprehensive software platform to
          interface with the Web, premium quality Internet access and
          support services and on-line tools to automate Web site creation
          and development.

               NETCOM owns and operates a data communications network
          consisting of 17 hubs containing frame relay switches and high-
          performance routers connecting a backbone of leased ATM switches
          and leased high-speed dedicated data lines in the United States,
          Canada and the United Kingdom. NETCOM maintains 247 POPs in the
          United States and Canada and also offers virtual local access
          numbers in Canada and the United Kingdom. The design and
          architecture of the physical network permits NETCOM to offer
          highly flexible, reliable high-speed services to its customers
          and support significant subscriber growth. The NETCOM
          infrastructure is monitored by NOCs in San Jose, Dallas, Toronto
          and London.

               NETCOM derives revenue from dial-up access, direct access
          and Web site hosting services. In January 1997, NETCOM announced
          plans to migrate its customer focus away from high volume, low
          margin consumer customers to higher margin products for small and
          medium-sized business customers. However, for fiscal 1997,
          revenue from dial-up access, direct access and Web site hosting
          services was $133.7 million, $19.5 million and $6.3 million,
          respectively, representing approximately 83%, 12% and 4%,
          respectively, of NETCOM's total revenue. Direct access customers
          typically purchase equipment and generate non-recurring start-up
          revenue. This initial non-recurring revenue was approximately 1%
          of NETCOM's revenue for fiscal 1997.

               Cost of revenue principally consists of labor costs, costs
          of leased long distance transmissions capacity, depreciation of
          network equipment, customer support costs, costs of equipment
          sold to customers and other miscellaneous costs. Transmission
          capacity is the largest component. NETCOM acquires transmission
          capacity through month-to-month (or longer) leases.

               Product development expenses are principally labor costs for
          programmers and engineers. These personnel are employed to
          integrate NETCOM's software with software of third party vendors
          and software and applications used on the Internet. The labor
          market for computer programmers is highly competitive and labor
          costs for such personnel have increased and is expected to
          continue to increase.


                                      -30-
     


               Sales and marketing expenses consist principally of
          commissions and advertising allocations paid to third party
          marketing organizations, advertising expenditures made directly
          by NETCOM and labor costs of NETCOM's internal sales force. In
          future periods, sales and marketing expense is expected to
          substantially increase, both in absolute dollars and as a
          percentage of revenue.

               Historically, NETCOM has not had significant interest
          expense. However, as a result of the Private Offering, interest
          expense will increase substantially.

               The Company expects to acquire telecommunications, Internet
          and related businesses that complement ICG's business strategy to
          offer a wide array of telecommunications, Internet and related
          services primarily to communications-intensive business
          customers. Acquisition targets could include U.S. or foreign
          CLECs, ISPs and long distance companies, among others. The
          Company intends to make future acquisitions primarily through the
          use of ICG Common Stock, cash on hand and the proceeds from
          securities offerings.

               Merger related costs incurred to effect the combination of
          NETCOM and ICG include registration fees, costs of furnishing
          information to stockholders, fees of finders and consultants,
          instituting efficiencies which are necessary to integrate the
          continuing operations of the combined corporation and other
          costs. All expenses related to effecting the combination will be
          recorded as expenses of the resulting combined corporation during
          the period in which the combination was consummated (January
          1998). The Company believes that total expenses incurred relating
          to the merger are approximately $8.3 million, which includes
          deferred expenses incurred prior to December 31, 1997,
          aggregating approximately $1.5 million.

          RESULTS OF OPERATIONS

          YEARS ENDED DECEMBER 31, 1997 AND 1996

               Revenue. Revenue increased by $40.1 million, or 33%, to
          $160.7 million for the year ended December 31, 1997 from $120.5
          million for the year ended December 31, 1996. The revenue
          increase was due to an increase in average revenue per customer,
          which resulted from an increase in the mix of direct access and
          Web site hosting customers relative to dial-up customers, sales
          of NETCOM's premium dial-up products and growth in the Internet
          market generally. During 1997, NETCOM experienced increases in
          dedicated and Web site hosting customers of 200% and 32%,
          respectively, and a decrease in dial-up accounts. The
          consolidated average revenue per customer increased approximately
          20% from 1996 to 1997. The total number of customers decreased by
          7% to approximately 539,000 customers as of December 31, 1997
          from approximately 580,000 customers as of December 31, 1996. In
          January 1997, NETCOM announced plans to migrate its customer
          focus away from high volume, low margin consumer customers to
          higher margin products for small and medium-sized business
          customers. As a result, NETCOM expects that the number of total
          subscribers will continue to decline in 1998, while revenue per
          customer will continue to increase. However, there can be no
          assurance that revenue per customer will continue to increase.

               International revenue increased by $10.7 million to $13.2
          million for the year ended December 31, 1997 from $2.5 million
          for the year ended December 31, 1996. The increase in
          international revenue is due to the increased subscriber base for
          NETCOM's international operations which began in 1996.

               Cost of revenue. Cost of revenue was $118.4 million for the
          year ended December 31, 1997 and $88.4 million for the year ended
          December 31, 1996, increasing to 74% of revenue from 73% of
          revenue, respectively.  The increase in cost of revenue during
          1997 was primarily attributable to NETCOM's international
          expansion, increased network, data communication and depreciation
          costs associated with network improvements and with expansion of
          NETCOM's operations and customer support staff.  Consolidated
          gross margin for the years ended December 31, 1997 and December
          31, 1996 was 26% and 27%, respectively. Domestic gross margin for
          the same period was 29% and 32%, respectively.


                                      -31-
     

               International cost of revenue for the year ended December
          31, 1997 was $13.6 million, an increase of $5.9 million over the
          year ended December 31, 1996. The increase in international cost
          of revenue in absolute dollars is due primarily to increased
          network and payroll related costs. NETCOM expects that cost of
          revenue for international operations will continue to increase in
          absolute dollars in the foreseeable future.

               Product development. Product development expenses were $6.5
          million for the year ended December 31, 1997 and $6.0 million for
          the year ended December 31, 1996, representing 4% and 5% of
          revenue, respectively.  The increase in product development costs
          was due to increased personnel in the development area. 
          International product development expenses for the year ended
          December 31, 1997 were $1.1 million compared to $54,000 in 1996.
          NETCOM plans to continue expenditures on product development as
          it develops new software products and upgrades existing products.
          It is expected that product development expenses as a percentage
          of revenue will remain relatively stable.

               Sales and marketing. Sales and marketing expenses decreased
          $1.9 million, or 4%, to $49.4 million for the year ended December
          31, 1997 from $51.2 million for the year ended December 31, 1996.
          The decrease in sales and marketing expenses, as a percentage of
          revenue, to 31% from 43% for the years ended December 31, 1997
          and December 31, 1996, respectively, was primarily attributable
          to decreases in advertising, trade show, and consulting expenses
          and decreased subscriber activity in the U.S.

               International sales and marketing expenses (including costs
          incurred domestically relating to international operations)
          increased by $1.9 million to $11.5 million for the year ended
          December 31, 1997 compared to the year ended December 31, 1996.
          International sales and marketing expenses are expected to
          continue to increase in absolute dollars but to decrease as a
          percentage of revenue.

               Certain of NETCOM's direct response advertising costs
          associated with subscriber acquisitions are capitalized in
          accordance the AICPA's Statement of Position 93-7 and amortized
          over a 12-month period using the straight-line method. NETCOM
          capitalized subscriber acquisition costs of approximately $6.5
          million and $14.4 million for the years ended December 31, 1997
          and December 31, 1996, respectively. Amortization of deferred
          subscriber acquisition costs for the years ended December 31,
          1997 and December 31, 1996 were $8.5 million and $12.2 million,
          respectively.

               General and administrative. General and administrative
          expenses decreased $1.3 million, or 6%, to $22.3 million for the
          year ended December 31, 1997 from $23.6 million for the year
          ended December 31, 1996, decreasing to 14% from 20% of revenue,
          respectively. The decrease in general and administrative expenses
          in absolute dollars and as a percentage of revenue was primarily
          due to costs incurred during 1996 of $.1 million with respect to
          moving a significant portion of NETCOM's operations into new
          buildings and $.7 million from writing-off accounts receivable
          balances determined to be uncollectible.

               International general and administrative expenses increased
          by $.1 million to $2.6 million for the year ended December 31,
          1997 compared to the year ended December 31, 1996. General and
          administrative expenses are expected to increase in absolute
          dollars.

               Restructuring and related charges. Restructuring and related
          charges of $1.9 million during the year ended December 31, 1997
          are the result of a decision by management to restructure
          operations of NETCOM's subsidiary in the United Kingdom. The
          restructuring charge is comprised of $1.4 million in accrued
          expenses for costs to terminate excess leased office facilities
          and a write-off of office equipment, furniture and building
          improvements as a result of consolidating office space, a $.3
          million write-down of previously capitalized deferred subscriber
          acquisition costs and $.2 million for severance costs.


                                      -32-
     


               Interest income and other, net. Interest income, net was
          $3.5 million and $5.7 million, respectively, for the years ended
          December 31, 1997 and 1996. The decrease was due to NETCOM's
          lower average balance of cash and cash equivalents during 1997 as
          compared to 1996. In addition, during 1997, NETCOM incurred
          interest expense on capital leases of $.5 million for 1997
          compared to no interest expense during the prior year. NETCOM
          invests its cash and cash equivalents primarily in high grade
          commercial paper and money market instruments.

               Provision for income taxes.  The provision for income taxes
          for 1997 and 1996 consisted solely of foreign taxes and state
          minimum taxes as NETCOM had pre-tax losses in both years.

               Net loss; EBITDA. Revenue growth and decreases in cost of
          revenue and operating expenditures as a percentage of revenue,
          offset by international expansion and restructuring charges
          related to the United Kingdom operations, resulted in reduced net
          losses of $33.1 million for 1997 as compared to net losses of
          $44.3 million for 1996. International net losses for 1997 were
          $18.3 million as compared to net losses of $18.0 million for
          1996.

               NETCOM believes EBITDA (earnings before interest, taxes,
          depreciation and amortization) is a cash flow measure used by
          analysts, investors and other parties interested in the Internet
          services industry. EBITDA losses for 1997 were $1.7 million as
          compared to EBITDA losses of $20.3 million for 1996. EBITDA
          before restructuring and related charges of $1.9 million was $.1
          million for 1997. Domestic EBITDA for 1997 was $11.6 million.

          YEARS ENDED DECEMBER 31, 1996 AND 1995

               Revenue. Revenue increased 130% to $120.5 million from $52.4
          million in 1995. The increase in revenue was due to a significant
          increase in the number of dial-up subscribers, direct access
          connections and Web site hosting accounts, which NETCOM
          attributes to the growth in the Internet market generally, the
          increase in the number of NETCOM local access areas, NETCOM's
          release of enhancements to its software, and continued expansion
          of NETCOM's sales, distribution and promotional activities.
          Subscribers increased by 88% to approximately 580,000 customers
          as of December 31, 1996 from approximately 308,000 customers as
          of December 31, 1995. NETCOM's international subsidiaries
          accounted for $2.5 million of total revenue in 1996.

               Cost of revenue. NETCOM's cost of revenue increased 141% to
          $88.4 million in 1996 from $36.6 million in 1995, increasing to
          73% from 70% of revenue, respectively. The increase in the cost
          of revenue (in absolute terms) during 1996 was primarily
          attributable to NETCOM's international expansion, sales tax
          charges, increased network, data communication and depreciation
          costs associated with the increased number of subscribers and
          network improvements and with expansion of NETCOM's operations
          and customer support staff. The amount relating to international
          operations in 1996 was $7.7 million. The increase as a percentage
          of revenue was primarily due to NETCOM's expansion
          internationally.

               Product development. Total product development expenses
          increased 169% to $6.0 million from $2.2 million in 1995,
          increasing to 5% from 4% of revenue, respectively. Of the 1996
          product development expenses, $54,000 related to international
          operations.

               Sales and marketing. Sales and marketing expenses increased
          173% to $51.2 million from $18.8 million in 1995, increasing to
          43% from 36% of revenue, respectively. The increase in sales and
          marketing expenses was due primarily to increased costs
          associated with NETCOM's international subsidiaries' sales and
          marketing expenses and subscriber acquisition activity in the
          U.S. The total for international operations in 1996 was $9.6
          million which includes costs incurred domestically relating to
          international operations. In addition, growth of costs associated
          with subscriber acquisition, the addition of management personnel
          and marketing programs in the U.S. attributed to the increase.
          NETCOM capitalized subscriber acquisition costs of approximately
          $14.4 million and $5.5 million and amortized and wrote off
          approximately $12.2 million and $2.8 million for 1996 and 1995,
          respectively. In 1996, of the amounts capitalized and amortized,
          $1.8 million and $.8 million, respectively, related to
          international operations.


                                      -33-
     


               General and administrative. General and administrative
          expenses increased 114% to $23.6 million in 1996 from $11.0
          million in 1995, and as a percent of revenue, general and
          administrative expenses decreased to 20% from 21%, respectively.
          The dollar increase was primarily attributable to additional
          administrative personnel, bad debt expense, additional corporate
          facility expenses and international operations. International
          operations accounted for $2.5 million of general and
          administrative expenses during 1996.

               Interest income, net. Interest income, net increased to $5.7
          million in 1996 from $2.2 million in 1995. This change is
          primarily the result of the investment of the proceeds from
          NETCOM's public offerings in May and November 1995, primarily in
          commercial paper.

               Provision for income taxes. The provision for income taxes
          for 1996 and 1995 consisted solely of foreign taxes and state
          minimum taxes as NETCOM had pre-tax losses in both years.

               Net loss; EBITDA. The higher cost of revenue and operating
          expenditures incurred in fiscal 1996, as described above,
          resulted in a net loss of $44.3 million as compared to a net loss
          of $14.1 million for 1995, notwithstanding the period to period
          revenue growth. This reflected NETCOM's strategy to invest in its
          international operations as well as in the growth of its
          subscriber base and local access numbers. EBITDA losses for
          fiscal 1996 and 1995 were $20.3 million and $6.3 million,
          respectively.

          LIQUIDITY AND CAPITAL RESOURCES

               NETCOM has used cash principally for capital expenditures
          and to fund operating losses. NETCOM has funded its operations to
          date primarily through cash revenue and private and public sales
          of equity securities. NETCOM's operating activities used cash of
          approximately $2.1 million, $21.7 million and $.5 million for
          1997, 1996 and 1995, respectively. During 1997, cash used in
          operating activities was primarily affected by the net loss,
          gains on investments, deferred subscriber acquisition costs and a
          $2.1 million payment in connection with its Brazilian investment,
          which investment was liquidated in December 1997. These uses of
          cash were primarily offset by depreciation and amortization and
          $2.2 million representing increases in deferred revenue. During
          1996, cash from operations was primarily used to fund the net
          loss, decreases in accounts payable and an increase in deferred
          subscriber acquisition costs. These uses of cash were partially
          offset by depreciation and amortization, liquidation of
          investments and increases in accrued payroll and related
          expenses, other accrued expenses and liabilities and deferred
          revenue.  In 1995, cash used in operations was primarily used to
          fund the net loss and increases in deferred subscriber
          acquisition costs.  These uses of cash were partially offset by
          depreciation and amortization and other non-cash losses and
          increases in other accounts payable, accrued expenses and
          payroll.

               Investing activities used net cash of $9.0 million, $54.0
          million and $44.7 million for 1997, 1996 and 1995, respectively.
          NETCOM's investing activities have consisted primarily of
          equipment purchases for new local access areas and network
          expansion. Cash capital expenditures were $10.9 million for 1997
          which were offset in part by the sale of short-term investments.

               Financing activities provided cash of $1.4 million,
          $2.4 million and $170.3 million for 1997, 1996 and 1995,
          respectively. For 1997, financing activities consisted primarily
          of the exercise of stock options, purchases under the employee
          stock purchase plan (which was dissolved in conjunction with
          NETCOM's merger with ICG in January 1998) and proceeds from
          issuance of debt relating to financing of equipment which was
          partially offset by principal payments on the capital leases
          entered into during the period. For 1996, financing activities
          consisted of proceeds from the exercise of stock options and
          purchases under the employee stock purchase plan.  For 1995,
          financing activities consisted primarily of proceeds from
          NETCOM's public offerings in May 1995 and November 1995.

               NETCOM has material capital commitments for its capital
          lease obligations and rental expense for its premises and a
          substantial portion of the proceeds of its May 1995 and November


                                     -34-
     


          1995 public offerings has been used for, and the Company expects
          to continue to use cash for, additional equipment purchases and
          subscriber acquisition costs. NETCOM has capital lease
          obligations of $6.0 million as of December 31, 1997. Furthermore,
          NETCOM has guaranteed monthly usage levels with WorldCom and has
          certain termination liabilities with its communications vendors
          (including WorldCom). The yearly commitments (exclusive of
          certain usage discounts) in the years 1998, 1999, 2000 and 2001
          are $9.3 million, $9.3 million, $7.6 million and $4.2 million,
          respectively. The aggregate termination liabilities as of January
          1, 1998 are approximately $15 million. In addition, NETCOM has
          minimum future rental payments under various noncancelable
          operating leases of $16.6 million as of December 31, 1997.

               As of December 31, 1997, NETCOM had cash and cash
          equivalents of $63.4 million and working capital of $38.7
          million. NETCOM used $14.9 million working capital in 1997.

               The Company believes that, under its business plan for the
          NETCOM business, the net proceeds from the Private Offering,
          together with vendor financing and cash from operations will be
          sufficient to meet anticipated working capital and capital
          expenditure requirements of its existing operations. However, the
          forward-looking information contained in the previous sentence
          may be affected by a number of factors, including the matters
          described in this paragraph and under "Risk Factors." The Company
          may need to raise additional capital from public or private
          equity or debt sources in order to finance its operations,
          capital expenditures and growth for periods after 1998. Moreover,
          the Company believes that continued growth and expansion through
          acquisitions, investments and strategic alliances is important to
          maintain a competitive position in the market and, consequently,
          a principal element of the Company's business strategy is to
          acquire assets or make investments in businesses that are
          complementary to its and ICG's current operations. The Company
          expects to acquire telecommunications, Internet and related
          businesses that complement ICG's business strategy to offer a
          wide array of telecommunications, Internet and related services
          primarily to communications-intensive business customers.
          Acquisition targets could include U.S. or foreign CLECs, ISPs and
          long distance companies, among others. The Company intends to
          make future acquisitions primarily through the use of ICG Common
          Stock, cash on hand and the proceeds from securities offerings.

               The Company may need to raise additional funds in order to
          take advantage of opportunities for acquisitions, investments and
          strategic alliances, to develop new products or to respond to
          competitive pressures or to fund capital expenditure requirements
          of any acquired businesses. There can be no assurance that the
          Company will be able to raise such capital on acceptable terms or
          at all. In the event that the Company is unable to obtain
          additional capital or is unable to obtain additional capital on
          acceptable terms, the Company may be required to reduce the scope
          of its presently anticipated acquisition opportunities and
          capital expenditures, which could have a material adverse effect
          on its business, results of operations and financial condition
          and could adversely impact its ability to compete and make
          payments on the New Notes.

                                       BUSINESS

          OVERVIEW

               ICG Services, Inc. provides Internet services, through its
          subsidiary, NETCOM, to individuals and to small and medium-sized
          businesses. The Company also acquires telecommunications
          equipment, software and capacity for lease or sale to other
          subsidiaries of ICG. In addition to providing these services, the
          Company intends to grow through acquisitions of
          telecommunications, Internet and related businesses that
          complement ICG's business strategy.

               The Company is a wholly owned subsidiary of ICG, one of the
          nation's leading ICPs of competitive communications services,
          based on estimates of the industry's 1997 revenue. ICG's
          objectives are to provide a wide range of local, long distance
          and data communications services to business end users and
          wholesale customers and to be a premier provider of high quality
          communications services to its targeted business and carrier
          customers. ICG believes that customers are increasingly demanding
          a broad, full service approach to providing services and that, by
          offering a bundled package, ICG will be better able to capture
          business from communications-intensive commercial customers.

          BUSINESS STRATEGY

               The Company's objective is to acquire and consolidate
          telecommunications, Internet and related businesses and bundle
          the services provided by these businesses with ICG's current
          competitive local and long distance telecommunications products.
          By leveraging the Company's relationship with ICG and utilizing
          ICG's extensive network footprint, the Company intends to capture
          the growth in demand from business customers for a full package
          of telecommunications services by offering a wide array of
          services, including Internet services.

               Market Services to Business End Users. The Company is
          focused on marketing a variety of telecommunications and Internet
          products and services primarily to business end users. Through
          its wholly owned subsidiary, NETCOM, the Company currently
          markets Internet services to individuals and to small and medium-
          sized businesses. In January 1997, NETCOM announced plans to
          migrate its customer focus away from high volume, low margin
          consumer customers to higher margin products for small and
          medium-sized business customers. Management believes a targeted
          business end user strategy can better leverage ICG's network
          footprint and telecommunications investment. To date, NETCOM has
          been successful in implementing this plan, and has seen its
          average revenue per customer increase from $21.47 during fiscal
          1996 to $23.92 during fiscal 1997.

               Concentrate on Regional Clusters. The Company believes that
          by focusing its growth on business activities located within
          ICG's network of regional clusters in California, Colorado, Ohio
          and the Southeast, it will be able to more effectively service
          its customers' needs and efficiently market, operate and control
          its network and expanded service offerings. In addition, the
          Company believes that by focusing future growth within ICG's
          existing footprint, it will be able to overlay ICG's support
          services and realize extensive cost synergies. For example, a
          significant portion of NETCOM's customer base is located in
          California. To the extent feasible, NETCOM will route its
          Internet traffic over ICG's California network. NETCOM plans to
          continue to operate and grow its business in the United States
          outside of ICG's network footprint and in Canada and the United
          Kingdom.

               Increase Revenue and Margins through Bundled Services. The
          Company intends to increase its revenue and margins by providing
          a full range of communications products to its end user
          customers. The Company plans to complement ICG's competitive
          local and long distance telecommunications offerings by combining
          the Internet products developed by NETCOM and cross-marketing
          these combined products through ICG's direct sales force.
          Additionally, NETCOM intends to market ICG telecommunications
          products to its small and medium-sized business customer base.

               Integrate Investments and Expand. The Company expects to
          acquire telecommunications, Internet and related businesses that
          complement ICG's business strategy to offer a wide array of
          telecommunications, Internet and related services primarily to
          business customers. Acquisition targets could include U.S. and
          foreign CLECs, ISPs and long distance companies, among others.
          The Company intends to make future acquisitions primarily through
          the use of ICG Common Stock, cash on hand and the proceeds from
          securities offerings.

               ICG and the Company believe that the acquisition of NETCOM
          is strategically important as it helps to (i) broaden ICG's
          communications product offerings to include Internet services and
          (ii) provide NETCOM with extensive network infrastructure for the
          on-net transportation of its Internet traffic. The Company will
          continue to look for acquisitions which it believes will benefit
          ICG's objectives to provide a wide range of local, long distance
          and data communications services to business end users and
          wholesale customers and to be a premier provider of high quality
          communications services to its targeted business and carrier
          customers.

                                        NETCOM

               NETCOM is a leading provider of high quality Internet
          solutions to individuals and small and medium-sized businesses in
          the United States and also provides the same high quality
          Internet solutions in Canada and the United Kingdom. NETCOM
          offers a broad spectrum of Internet solutions designed to enhance
          customer productivity through the integration and application of
          technologies by providing a comprehensive software platform to
          interface with the Web, premium quality Internet access and
          support services and on-line tools to automate Web site creation
          and development. These offerings have led to significant growth,
          with revenue increasing from approximately $2.4 million for 1993
          to approximately $160.7 million for fiscal 1997. In January 1997,
          NETCOM announced plans to migrate its customer focus away from
          high volume, low margin consumer customers to higher margin
          products for small and medium-sized business customers.

               NETCOM owns and operates a data communications network
          consisting of 17 hubs containing frame relay switches and high-
          performance routers connecting a backbone of leased ATM switches
          and leased high-speed dedicated data lines in the United States,
          Canada and the United Kingdom. NETCOM maintains 247 POPs in the
          United States and Canada and also offers virtual local access
          numbers in Canada and the United Kingdom. The design and
          architecture of the physical network permits NETCOM to offer
          highly flexible, reliable high-speed services to its customers
          and support significant subscriber growth. The NETCOM
          infrastructure is monitored by NOCs in San Jose, Dallas, Toronto,
          and London.

               NETCOM provides Internet solutions principally through dial-
          up, direct access and Web site hosting services. Direct access
          and Web site hosting services provide higher revenue per customer
          and higher margins than dial-up services. NETCOM also receives
          revenue from value-added services such as security, anti-virus
          and data storage.

          Market Overview

               The Internet is a global collection of thousands of computer
          networks cooperating to enable commercial organizations,
          educational institutions, government agencies and individuals to
          communicate electronically, to access and share information and
          to conduct business. The Internet originated with the ARPAnet, a
          restricted network started in 1969 by the United States
          Department of Defense to provide efficient and reliable long-
          distance data communications among the disparate computer systems
          used by government funded researchers and organizations. Unlike
          other public and private telecommunications networks that are
          managed by businesses, government agencies and other entities,
          the Internet is a cooperative interconnection of many such public
          and private networks. The networks that comprise the Internet are
          connected in a variety of ways, including by the public switched
          telephone network and by high speed, dedicated leased lines. Open
          communications on the Internet are enabled by TCP/IP, an
          internetworking standard that enables communication across the
          Internet regardless of the hardware and software used. In the


                                       -37-
     


          late 1980s and early 1990s, the use of the Internet by businesses
          and universities as a communications and research tool began to
          grow dramatically. In 1993, Web technology was introduced to the
          Internet paving the way for rapid commercialization of the
          Internet on a global basis. Since the introduction of the Web,
          continual technological advances, including new and innovative
          software applications, have led to a more robust, lower-cost
          infrastructure, improved security, an expanded array of enhanced
          services and a dramatic increase in content.

               Internet access services is one of the fastest growing
          segments of the telecommunications services market. According to
          industry research analysts, the market for consumer and business
          Internet connectivity and enhanced services exceeded $3 billion
          in 1996, and is estimated to reach $18 billion in revenue by the
          year 2000, reflecting a compounded annual growth rate of
          approximately 50%. Business connectivity and value-added services
          are estimated to represent in excess of 50% of the overall
          market. The use of the Internet by small and medium-sized
          businesses in particular is expected to grow substantially from
          its current low levels of market penetration.

               ISPs provide customers with a variety of services to meet
          their Internet-related needs. Internet services include the
          following categories: (1) access services (dial-up, direct access
          and Web site hosting); (2) value-added services (security
          services, anti-virus and data storage); and (3) content services
          (information creation, aggregation and delivery). Some ISPs offer
          all of these services while others specialize in only one or two.
          As the market continues to segment in these three areas, there
          are opportunities for both the specialists who can provide
          superior service in one area, as well as full-service providers
          who can bundle services and offer discounts. There were over
          4,300 ISPs in the United States and Canada as of October 31, 1997
          compared to just over 3,000 as of October 31, 1996. There have
          been some large acquisitions of ISPs as CLECs and others attempt
          to enter the industry. Because of low barriers to entry, there
          are local and regional ISPs entering the market, which has caused
          the level of competition to intensify.

               The availability of an expansive variety of compelling
          business and consumer applications over the Internet has
          attracted a large number of consumer and business users. The
          total number of connections to ISP networks, according to
          International Data Corporation ("IDC"), was 17 million as of
          November 1997, and is predicted to reach over 30 million by the
          year 2000. Aggregate revenue from the retail segment of the ISP
          industry exceeded $3 billion in 1996. Market trends contributing
          to the overall growth in connectivity include advancements in
          technologies required to navigate the Internet, the availability
          of Internet connectivity, and the rich consumer and business
          content available. The Company believes that ongoing development
          of access to and applications of the Internet will continue to
          attract a valuable consumer audience for businesses.

          Market Growth

               Industry analysts anticipate continued rapid growth for the
          ISP market. Specifically, IDC forecasts the ISP market's annual
          aggregate revenue to grow from $3.3 billion in 1996 to $18.3
          billion in the year 2000, excluding content revenue.

          depicting the percentage breakdown of annual revenue for each of
          the four markets comprising the ISP market for years 1996 and
          2000 (forecast).  The overall size of the pie chart for the year
          2000 is larger than that for the year 1996, representing the
          greater total revenue in the year 2000.  The charts, however, are
          not drawn to scale.

               In addition to connectivity solutions, business customers
          increasingly are seeking a variety of value-added solutions to
          take full advantage of the Internet. Technological advances such
          as increases in microprocessor speeds, the introduction of
          innovative software tools and the development of higher bandwidth
          data networking technology have led to rapid innovation and
          development of value-added Internet services. The principal
          value-added services being offered among business oriented ISPs
          today include Web site hosting services, security solutions,
          commerce solutions, intranet services, business content, and
          advanced Internet applications such as voice and video
          conferencing and data storage and retrieval solutions. Value-
          added solutions are projected by industry analysts to increase to
          $7 billion in revenue by the year 2000 from $130 million in 1996.

               As a result of the growing Internet audience, businesses
          have discovered that the Internet provides a valuable marketing
          forum and can enhance communications with customers,
          geographically distributed offices and business partners,
          allowing them to quickly reduce operating costs, access valuable
          information and reach additional markets. Increasingly,
          businesses are utilizing the Internet for mission-critical
          applications such as sales, customer service and project
          coordination. In addition, a growing number of businesses are
          implementing secured virtual private networks over the Internet,
          as a more economical option to dedicated private networks, in
          order to provide internal company communications (intranets) and
          to link with their customers and suppliers (extranets). According
          to IDC, corporate access revenue from the retail segment of the
          ISP industry was approximately $1.9 billion in 1996.

               Access-related revenue is projected by industry analysts to
          approach $10 billion by the year 2000. Most of the growth in
          access revenue is expected to be attributable to dedicated
          access.

          The NETCOM Solution

               NETCOM's mission is to help individual professionals and
          small and medium-sized businesses work more productively using
          the Internet. Historically, NETCOM and other ISPs have pursued a
          customer acquisition strategy based on offering a $19.95 per
          month, flat-rate unlimited Internet dial-up access product, which
          is both high volume and low margin. In January 1997, NETCOM
          announced plans to migrate its customer focus away from high
          volume, low margin consumer customers to higher margin products
          for small and medium-sized business customers. NETCOM's solution
          is to offer a variety of packages that a customer can tailor to
          its specific needs and to offer premium performance and customer
          service. NETCOM believes that those customers that demand extra
          services (more mailboxes, research library access, anti-virus
          software) will be willing to pay more if they are assured
          convenience and reliability. NETCOM plans to gradually migrate
          its existing customer base to higher margin premium services and
          expects that low use, low margin customers will switch to lower-
          cost providers. NETCOM has designed a series of packages aimed at
          addressing the different needs of its customers.

               Dial-Up Services. NETCOM's dial-up customers receive an
          integrated Internet solution consisting of high quality access,
          software and 24 hours a day, seven days a week, automated
          customer support. NETCOM dial-up customers connect directly to
          the Internet via NETCOM's own network which provides high speed,
          reliable access. All NETCOM dial-up accounts allow access to the
          Internet's resources, including E-mail, the Web and USENET
          newsgroups. In addition, NETCOM dial-up customers can receive a
          one Mb personal Web page, access to a daily customized newspage
          via E-mail, and access to on-line financial, corporate and market
          information and analytical tools. Enhanced services available to
          dial-up customers include features such as additional E-mail
          addresses, enhanced support offerings, software and virus
          updates, access to research libraries, a domain name service,
          monthly back-up, 10 Mb data storage, 750 Mb per month data
          transfer capability and premium service and technology support.

               NETCOM customers can quickly register using NETCOMplete
          software, available for both Windows and Macintosh platforms via
          compact disk, and set up a NETCOM account by following a sequence

                                      -40-
     


          of simple, on-screen steps. All of the software needed to connect
          and access the Internet is automatically installed and
          configured, eliminating the need for complex set up procedures.
          NETCOMplete also provides an easy-to-use interface as well as
          software from leading industry participants, bookmark managers,
          off-line browsers and additional software that enhances a
          customer's Internet experience. Revenue from dial-up services
          increased from $102.9 million for fiscal 1996 to $133.7 million
          for fiscal 1997, representing approximately 85% and 83%,
          respectively, of total revenue for such periods.

               Direct Access Services. NETCOM offers a full suite of high-
          speed dedicated Internet connection and service products which
          provide its small and medium-sized business customers with direct
          access to the full range of Internet applications. These Internet
          services are offered to businesses over leased lines at various
          speeds, including 56 Kbps, T-1 and T-3 levels, depending upon the
          customer's needs. Through its direct access product line, NETCOM
          offers Internet access services including domain name and IP
          address, router configurations, on-line usage statistics and
          security consultation. There are generally no usage charges for
          any of NETCOM's dedicated customers, and E-mail service and
          USENET news feed are provided at no additional charge. Direct
          network connection requires the customer to obtain a leased line
          from ICG or another local telephone company. NETCOM provides an
          Internet connection based on frame relay technology provided by
          local telephone carriers. Revenue from direct access services
          increased from $16.3 million for fiscal 1996 to $19.5 million for
          fiscal 1997, representing approximately 14% and 12%,
          respectively, of total revenue for such periods.

               Web Site Hosting Services. NETCOM offers Web site hosting
          services to its small and medium-sized business customers as well
          as to individuals. Web site hosting services include client
          domain name registration, hosting and site maintenance. Services
          provided are fully scalable, but would, in a typical package,
          include domain name registration, 10 E-mail addresses, access to
          NETCOM's on-line Business Center, CGI scripting (which enables
          visitors to the Web site to leave their names and addresses),
          weekly back-up service, 50 Mb of data storage, 1,000 Mb per month
          of data transfers, traffic logs and Web statistics and premium
          service and technology support. Revenue from Web site hosting
          services increased from $1.3 million fiscal 1996 to $6.3 million
          for fiscal 1997, representing approximately 1% and 4%,
          respectively, of total revenue for such periods.

               Value-Added Services. As part of its dial-up client access
          and Web site hosting services, NETCOM offers its small and
          medium-sized business customers value-added business connectivity
          solutions packages designed to address their needs of increased
          security, reliability, access speed and customer service. The
          Company believes that businesses are willing to pay premium
          prices for these premium services. One such feature is Automatic
          Reconnect which automatically reroutes a customer's traffic to an
          alternate ISDN line so that in the event of certain kinds of
          service interruptions, customers may remain connected. In order
          to provide a secure, private connection among multiple specific
          locations, NETCOM's SecureConnect product performs a security
          assessment and then implements, monitors and troubleshoots a

          Software and Services Development

               NETCOM has placed significant emphasis on developing its
          products and services, both internally and through third party
          arrangements. NETCOM's newest software package, NETCOMplete,
          features NETCOM's versions of leading products including
          Microsoft Internet Explorer 4.0 or Netscape Navigator 3.0,
          Qualcomm Eudora Light, McAfee Webscan, SurfWatch Software and
          Service, VocalTec Internet Phone and Internet Phone Lite, NETCOM
          Unplugged by WebEx, NETCOM Unplugged Lite, Storm EasyPhoto,
          Macromedia Shockwave, Adobe Acrobat Reader, OnBase DragNet and
          DragNet Lite, NCSA Telnet, Quarterdeck Global Chat, IBM
          Cryptolope, Microsoft NetMeeting, Internet Mail, Internet News
          and Comic Chat. NETCOM intends to design additional features into
          future versions of NETCOMplete and additional products.
          Additionally, NETCOM will continue to enhance the ease of
          installation and automatic configuration of its products.

          Marketing and Distribution

               NETCOM's primary focus is on providing high quality Internet
          solutions to individuals and to small and medium-sized
          businesses. In order to achieve this objective, NETCOM engages in
          marketing and advertising activities, alliances with key
          strategic partners, seminars in targeted regional markets, and
          distribution via both direct and indirect channels. NETCOM's
          current marketing efforts emphasize its strategy of focusing on
          providing premium services to businesses and individuals through
          integrated product offerings. The campaign incorporates the theme
          of productivity and efficiency and includes an emphasis on the
          full range of NETCOM solutions. NETCOM's current distribution
          channels include the following:

               OEM. Original equipment manufacturer arrangements with
          computer, hardware, software and modem manufacturers account for
          a significant portion of NETCOM's new accounts. NETCOM's CPU OEM
          partners include Hewlett Packard Company, Acer America
          Corporation and NEC Corporation. NETCOM has also entered into a
          number of bundling arrangements with software companies,
          including Netscape Corp. and Microsoft Corporation. Arrangements
          with modem manufacturers such as U.S. Robotics and Global Village
          Communication account for a significant portion of OEM activity.
          New agreements with companies such as Cisco and Farallon
          Computing, Inc. will be increasingly focused on Web site hosting
          and direct access.


                                      -42-
     

               VAR. As NETCOM increases its focus on providing solutions to
          small and medium-sized business segments, the value added
          resellers who support this segment will become an increasingly
          active channel of distribution, selling the entire suite of
          NETCOM products. The network of NETCOM VARs are supported by
          NETCOM sales representatives both in the regional territories and
          in the Telesales center. Current VARs include Transnet
          Corporation, Nova Quest Infosystems, PC Solutions, Kissane
          Business Systems, Inc. and Cohesive Systems, Inc.

               Retail. A significant portion of NETCOM's new accounts is
          generated through retail distribution of NETCOMplete compact
          disks, which currently are offered in two versions. One is
          offered at a suggested retail price of $4.95; the other is a
          larger package featuring extensive third party software and books
          for a suggested retail price of $39.95. NETCOM's distributors
          include national chains such as CompUSA, Circuit City Stores,
          Inc., and Computer City, as well as regional entities such as
          Fry's Electronics, Inc. NETCOM distributes to retailers through
          national distributors such as Ingram Micro, Inc. and TechData
          Corporation, and through regional distributors such as Liuski
          International, Inc. Retail coverage is also provided via the OEM
          agreements described above.

               Telesales. A significant portion of NETCOM's business is
          conducted through inbound and outbound Telesales efforts.
          Telesales support business generated by direct marketing
          activities, trade shows and referrals, and is aligned to support
          the focus on targeted regional markets.

               The Web. NETCOM also generates a portion of its revenue from
          customers who sign up for services by accessing NETCOM's Web
          site.

          Customer Support

               NETCOM believes that it is important to provide prompt and
          effective assistance to its subscribers. NETCOM provides network
          monitoring and technical assistance services 24 hours a day,
          seven days a week. Most support personnel respond to telephone
          inquiries and inquiries from E-mail, faxes and letters. There are
          also a significant number of personnel dedicated to building
          automated support systems such as on-line knowledgebases, fax-on-
          demand systems and interactive voice response systems. The
          demands on NETCOM's customer support resources have increased
          with NETCOM's rapidly changing subscriber base, and NETCOM has
          from time to time experienced difficulties in providing adequate
          levels of support. An October 1997 customer satisfaction survey
          by NETCOM revealed customer support and customer service as a
          primary source of customer dissatisfaction. NETCOM is aware that
          its systems require investments to meet the more complex needs of
          its customers, especially its small to medium-sized business
          customers. NETCOM is taking steps to help customer support
          resources keep pace with projected increases in subscribers'
          demands. During 1997, NETCOM increased its customer support staff
          by 44 employees to 285 employees on December 31, 1997. NETCOM
          also implemented automated support services such as the WebTech
          Online Knowledgebase, the SupportFacts fax-on-demand system, and
          an Interactive Voice Response system, which significantly
          increased the support group's capacity to handle queries and
          improve customer satisfaction. NETCOM intends to continue to
          improve its customer support capabilities in order to keep pace
          with changes in NETCOM's subscriber base; however, there can be
          no assurance that NETCOM will be successful in doing so. See
          "Risk Factors -- Integrations of Acquired Business" and "--
          Dependence on Key Personnel."

          Data Communications Infrastructure

               NETCOM maintains an extensive data communications
          infrastructure that enables it to provide nationwide digital
          Internet connectivity services to its subscribers. NETCOM's
          network of POPs provides Internet access to subscribers by means
          of a dedicated line or local telephone call. NETCOM's ability to
          offer efficient access to the Internet is due in part to NETCOM's
          high-capacity data communications network, configured exclusively
          for facilitating Internet access. NETCOM's United States network
          consists of 13 regional hubs, each containing carrier grade frame
          relay switches and high capacity routers. These hubs are
          interconnected via a fiber optic T-3, 45 Mbps backbone and ATM
          transport together with other high-speed data connections between
          the T-3 backbone and NETCOM's POPs. The T-3 backbone connects to


                                   -43-
     


          Internet gateways in Santa Clara (at two sites), California, San
          Jose, California, Newark, New Jersey, Chicago, Illinois and
          Washington, D.C. In addition, NETCOM has Internet gateways in
          Toronto and London.

               NETCOM maintains two NOCs in the United States: one at its
          San Jose headquarters and the other in Dallas. Through these
          centers, NETCOM's technical staff continually monitors network
          utilization and security, including equipment at individual local
          access numbers, to ensure reliable Internet connectivity service.
          NETCOM's Dallas center reduces its dependence on its primary San
          Jose facilities. However, this does not eliminate the significant
          risk to NETCOM's operations from a natural disaster or other
          unanticipated event at one of these two sites. See "Risk Factors
          -- Dependence on Network Infrastructure; Risk of System Failure;
          Security Risks." Internationally, NETCOM has NOCs in Toronto and
          London.


                                     -44-
     

               NETCOM is continuing to enhance capacity and capabilities of
          its data communications network. NETCOM continues to add ATM
          switches, and plans to continue increasing capacity as its
          customer base increases. Additionally, NETCOM has efforts
          currently underway to increase the available dial-up speeds. As
          of December 31, 1997, NETCOM had 247 POPs in the United States
          and Canada, as listed below. Furthermore, NETCOM offers virtual
          local access lines in Canada and the United Kingdom.

          Competition

               The market for Internet access and related services is
          highly competitive. There are no substantial barriers to entry
          and the Company anticipates that competition will continue to
          intensify as the use of the Internet grows. The tremendous growth
          and potential market size of the Internet access market has
          attracted many new start-ups as well as existing businesses from
          different industries. Current and prospective competitors
          include, in addition to other national, regional and local ISPs,
          long distance and local exchange telecommunications companies,
          cable television, direct broadcast satellite, wireless
          communications providers, and on-line service providers.

               ISPs. According to industry sources, there are over 4,300
          ISPs in the United States and Canada as of October 31, 1997,
          consisting of national, regional and local providers. The
          Company's current primary competitors include other ISPs with a
          significant national presence which focus on business customers,
          such as UUNet Technologies, BBN and PSINet. While the Company
          believes that its level of local service and support and target
          market focus distinguish it from these competitors, many of these
          competitors have significantly greater market share, brand
          recognition, and financial, technical and personnel resources
          than the Company. The Company also competes with unaffiliated
          regional and local ISPs in its targeted geographic regions.

               Telecommunications Carriers. The major long distance
          companies (also known as interexchange carriers or IXCs),
          including AT&T, MCI, and Sprint, offer Internet access services
          and compete with the Company. The recent sweeping reforms in the
          federal regulation of the telecommunications industry have
          created greater opportunities for ILECs, including the RBOCs and
          other competitive CLECs, to enter the Internet connectivity
          market. In order to address the Internet connectivity
          requirements of the business customers of long distance and local
          carriers, the Company believes that there is a move toward
          horizontal integration by ILECs through acquisitions or joint
          ventures with and the wholesale purchase of connectivity from
          ISPs. The WorldCom/MFS/UUNet consolidation and GTE's recent
          acquisition of BBN are indicative of this trend. Accordingly, the
          Company expects that it will experience increased competition
          from the traditional telecommunications carriers. Many of these
          telecommunications carriers, in addition to their substantially
          greater network coverage, market presence, and financial
          technical and personnel resources, also have large existing
          commercial customer bases.

               Cable Companies, Direct Broadcast Satellite and Wireless
          Communications Companies. Many of the major cable companies have
          announced that they are exploring the possibility of offering
          Internet connectivity, relying on the viability of cable modems
          and economical upgrades to their networks. Continental
          Cablevision, Inc. and TCI have recently announced trials to
          provide Internet cable service to their residential customers in
          select areas. However, the cable companies are faced with large-
          scale upgrades of their existing plant equipment and
          infrastructure in order to support connections to the Internet
          backbone via high-speed cable access devices. Additionally, their
          current subscriber base and market focus is residential which
          requires that they partner with business-focused providers or
          undergo massive sales and marketing and network development
          efforts in order to target the business sector. Several
          announcements also have recently been made by other alternative
          service companies approaching the Internet connectivity market
          with various wireless terrestrial and satellite-based service
          technologies. These include Hughes Network Systems' announcement
          that it will provide high-speed data through direct broadcast
          satellite technology; CAI Wireless Systems, Inc.'s announcement
          of an MMDS wireless cable operator launching data services via
          2.5 to 2.7 GHz and high-speed wireless modem technology; and
          Winstar Communications, a 38 GHz radio company that wholesales
          its network capacity to other carriers and now offers high-speed
          Internet access to business customers.


                                      -46-
     

               On-line Service Providers. The dominant on-line service
          providers, including Microsoft Network, America Online,
          Compuserve, Inc. and Prodigy, Inc., have all entered the Internet
          access business by engineering their current proprietary networks
          to include Internet access capabilities. The Company competes to
          a lesser extent with these service providers, which currently are
          primarily focused on the consumer marketplace and offer their own
          content, including chat rooms, news updates, searchable reference
          databases, special interest groups and shopping. While Compuserve
          recently announced it will also target Internet connectivity for
          the small to medium-sized business market, this will require a
          significant transition from a consumer market focus to a business
          market focus.

               The Company believes that its ability to attract business
          customers and to market value-added services are keys to its
          future success. However, there can be no assurance that its
          competitors will not introduce similar pricing plans at
          comparable or more attractive prices in the future or that the
          Company will not be required to reduce its prices to match
          competition. Recently, many competitive ISPs have shifted their
          focus from individual customers to business customers. Moreover,
          there can be no assurance that more of the Company's competitors
          will not shift their focus to attracting business customers,
          resulting in even more competition for the Company. There can be
          no assurance that NETCOM will be able to offset the effects of
          any such competition or resulting price reductions through an
          increase in the number of its subscribers, higher revenue from
          enhanced services, cost reductions or otherwise. Increased
          competition could result in erosion of NETCOM's market share and
          adversely affect NETCOM's operating results. See "Risk Factors --
          Competition."

          Intellectual Property and Other Proprietary Rights

               NETCOM relies on a combination of worldwide copyright and
          trademark laws, trade secrets, software security measures,
          license agreements and nondisclosure agreements to protect its
          proprietary technology and software products. NETCOM currently
          has no domestic or foreign patents or patent applications
          pending. However, NETCOM does have registered or pending
          trademarks in various countries including the United States.
          NETCOM from time to time receives notices claiming that it is
          infringing the proprietary rights of third parties. Any such
          claims could be time-consuming, result in costly litigation,
          cause product shipment delays or lead NETCOM to enter into
          royalty or licensing agreements rather than disputing the merits
          of such claims. For a more extensive discussion on intellectual
          property and rights, see "Risk Factors -- Limited Intellectual
          Property Protection."

          Employees

               As of December 31, 1997, NETCOM employed 813 persons,
          including 147 in operations, 285 in customer support, 174 in
          marketing and distribution, 147 in administration and 60 in Web
          site and software integration, all of whom are full-time
          employees. None of NETCOM's employees is represented by a labor
          union and NETCOM considers its employee relations to be good.

          Properties

               NETCOM's executive offices and data communications centers
          are located in San Jose, California, where the Company currently
          leases approximately 183,000 square feet under various leases in
          three buildings that expire during various months in 1999. In
          addition, the Company leases approximately 60,800 square feet in
          Dallas, Texas for its second data communications center. The
          Company also leases space (typically less than 500 square feet)
          in various geographic locations to house the telecommunications
          equipment for each of its local access numbers. The Company's
          Canadian subsidiary leases approximately 19,600 square feet in
          Toronto, Canada. The Toronto lease expires in December 2000. The
          Company's United Kingdom subsidiary leases approximately 22,800
          square feet in Bracknell, United Kingdom. The United Kingdom
          lease expires in March 2014.

          Litigation

               A putative class action lawsuit, Adam L. Swinehart, on
          behalf of himself and others similarly situated v. NETCOM On-Line
          Communication Services, Inc., was filed on July 15, 1997 in the
          Superior Court of California, Orange County, alleging unfair
          business practice and related causes of action against NETCOM in
          connection with its offers of free trial periods and cancellation
          procedures and claiming damages of at least $10 million. The case
          is in preliminary stages, the complaint has been answered and
          plaintiff has served initial requests for discovery. NETCOM
          believes it has meritorious defenses to such claims and intends
          to vigorously defend the action.

               The Federal Trade Commission ("FTC") is conducting an
          inquiry regarding the advertising, marketing, subscription and
          billing practices of NETCOM. NETCOM believes that it has made
          reasonable efforts to comply with applicable laws. If the FTC
          were to conclude that NETCOM violated any applicable law, it
          could seek relief in the form of equitable relief, civil monetary
          penalties, or other remedies.

               The Company is from time to time involved in litigation in
          the course of its business. The Company is currently involved in
          certain other litigation and potential claims which management
          believes, based on facts presently known, will not have a
          material adverse effect on the Company's business, operating
          results or financial condition. In addition, from time to time
          the Company receives notices claiming that it is infringing the
          proprietary rights of third parties, and there can be no
          assurance that the Company will not become the subject of
          infringement claims or legal proceedings with third parties with
          respect to current or future products. See "Business --
          Intellectual Property and Other Proprietary Rights."

           Sheldon S. Ohringer . .   41  Director

               J. Shelby Bryan was appointed Chairman of the Board of
          Directors, President and Chief Executive Officer of the Company
          in January 1998. In May 1995, Mr. Bryan was appointed President,
          Chief Executive Officer and a Director of ICG. He has 18 years of
          experience in the telecommunications industry, primarily in the

                    CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

               ICG intends to enter into arrangements with ICG Equipment to
          purchase, lease, license or enter into right-of-use arrangements,
          for telecommunications equipment, software and capacity and
          related services. The equipment and services provided to ICG will
          be utilized to upgrade and expand its network infrastructure to
          take full advantage of the opportunities and cost savings
          available as a result of the acquisitions made by the Company.
          Any such arrangements will be on an arm's length basis and on
          comparable terms ICG would be able to obtain from a third party.

               Messrs. Bryan, Grenfell, Teague and Ohringer are also

          certain services, such as accounting, legal, operations, network
          and general corporate services as needs arise. All such services
          will be priced and consideration paid on an arm's length basis in
          accordance with the terms of the ICG Indentures.

                                  THE EXCHANGE OFFER

          PURPOSE AND EFFECT OF THE EXCHANGE OFFER

               The Old Notes were sold by Morgan Stanley & Co. Incorporated
          (the "Placement Agent") on February 12, 1998 to a limited number
          of institutional investors (the "Purchasers"). In connection with
          the sale of the Old Notes, the Company and the Placement Agent
          entered into a registration rights agreement dated February 12,
          1998 (the "Registration Rights Agreement"), which requires, among
          other things, the Company (i) to cause the Old Notes to be
          registered under the Securities Act or (ii) to use its best
          efforts to cause to be filed with the Commission a registration
          statement under the Securities Act with respect to New Notes
          identical in all material respects to the Old Notes and have such
          registration statement declared effective under the Securities
          Act and remain effective until the closing of the Exchange Offer.
          The Company is further obligated, upon the effectiveness of that
          registration statement, to offer the holders of the Old Notes the
          opportunity to exchange their Old Notes for a like principal
          amount of New Notes which will be issued without a restrictive
          legend and may be reoffered and resold by the holder without
          restrictions or limitations under the Securities Act. A copy of
          the Registration Rights Agreement has been filed as an exhibit to
          the Registration Statement of which this Prospectus is a part.
          The Exchange Offer is being made pursuant to the Registration
          Rights Agreement to satisfy the Company's obligations thereunder.
          The term "Holder" with respect to the Exchange Offer means any
          person in whose name Old Notes are registered on the Company's
          books or any other person who has obtained a properly completed
          assignment from the registered holder.

               In order to participate in the Exchange Offer, a Holder must
          represent to the Company, among other things, 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 the Holder, (ii) neither
          the Holder nor any such other person is engaging in or intends to
          engage in a distribution of such New Notes, (iii) neither the
          Holder nor any such other person has an arrangement or
          understanding with any person to participate in the distribution
          of such New Notes, and (iv) neither the Holder nor any such other
          person is an "affiliate," as defined under Rule 405 promulgated
          under the Securities Act, of the Company.

               Based on a previous interpretation by the staff of the
          Commission set forth in no-action letters issued to third-
          parties, including "Exxon Capital Holdings Corporation"
          (available May 13, 1988), "Morgan Stanley & Co. Incorporated"
          (available June 5, 1991), "Mary Kay Cosmetics, Inc." (available
          June 5, 1991), "Warnaco, Inc." (available October 11, 1991) and
          "K-III Communications Corp." (available May 14, 1993), the
          Company believes that the New Notes issued pursuant to the
          Exchange Offer may be offered for resale, resold and otherwise
          transferred by any Holder of such New Notes (other than any such
          Holder which is an "affiliate" of the Company within the meaning
          of Rule 405 under the Securities Act) without compliance with the
          registration and prospectus delivery provisions of the Securities
          Act, provided that such New Notes are acquired in the ordinary
          course of such Holder's business and such Holder has no
          arrangement or understanding with any person to participate in
          the distribution of such New Notes. Any Holder who tenders in the
          Exchange Offer for the purpose of participating in a distribution
          of the New Notes cannot rely on such interpretation by the staff
          of the Commission and must comply with the registration and
          prospectus delivery requirements of the Securities Act in
          connection with a secondary resale transaction. Under no
          circumstances may this Prospectus be used for an offer to resell,
          resale or other retransfer of the New Notes. In the event that
          the Company's belief is inaccurate, Holders of the New Notes who
          transfer New Notes in violation of the prospectus delivery
          provisions of the Securities Act and without an exemption from
          registration thereunder may incur liability thereunder.  The
          Company does not assume or indemnify Holders against such
          liability. 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. 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.  The Company has not entered into
          any arrangement or understanding with any person to distribute
          the New Notes to be received in the Exchange Offer. See "Plan of
          Distribution."


                                      -51-
      


          TERMS OF THE EXCHANGE OFFER

               Upon the terms and subject to the conditions set forth in
          this Prospectus and in the Letters 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. The Company will issue $1,000 principal amount
          of New Notes in exchange for each $1,000 principal amount of
          outstanding Old Notes surrendered pursuant to the Exchange Offer. 
          However, Old Notes may be tendered only in integral multiples of
          $1,000.

               The form and terms of the New Notes will be the same as the
          form and terms of the Old Notes except that the New Notes will be
          registered under the Securities Act and hence will not bear
          legends restricting the transfer thereof. The New Notes will
          evidence the same debt as the Old Notes. The New Notes will be
          issued under and entitled to the benefits of the Indenture, which
          also authorized the issuance of the Old Notes, such that both
          series will be treated as a single class of debt securities under
          the Indenture. 

               As of the date of this Prospectus, $490,000,000 aggregate
          principal amount at maturity of the Old Notes is outstanding.
          This Prospectus, together with the Letter of Transmittal, is
          being sent to all registered Holders of the Old Notes.

               The Company intends to conduct the Exchange Offer in
          accordance with the provisions of the Registration Rights
          Agreement and the applicable requirements of the Exchange Act,
          and the rules and regulations of the Commission thereunder. Old
          Notes that are not tendered for exchange in the Exchange Offer
          will remain outstanding and will be entitled to the rights and
          benefits such Holders have under the Indenture. 

               The Company shall be deemed to have accepted validly
          tendered Old Notes when, as and if the Company shall have given
          oral or written notice thereof to the Exchange Agent.  The
          Exchange Agent will act as agent for the tendering Holders for
          the purposes of receiving the New Notes from the Company.

               If any tendered Old Notes are not accepted for exchange
          because of an invalid tender, the occurrence of certain other
          events set forth herein or otherwise, certificates for any 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 pursuant to the Exchange Offer. The
          Company will pay all charges and expenses, other than certain
          applicable taxes described below, in connection with the Exchange
          Offer. See "-- Fees and Expenses."

          EXPIRATION DATE; EXTENSIONS; AMENDMENTS

               The term "Expiration Date," shall mean 5:00 p.m., New York
          City time on           , 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.

               In order to extend the Exchange Offer, the Company will
          notify the Exchange Agent of any extension by oral or written
          notice and will mail to the registered Holders an announcement
          thereof, prior to 9:00 a.m., New York City time, on the next
          business day after the then Expiration Date.

               The Company reserves the right, in its sole discretion, (i)
          to delay accepting any Old Notes, to extend the Exchange Offer or
          to terminate the Exchange Offer if any of the conditions set
          forth below under "--Conditions" shall not have been satisfied by
          giving oral or written notice of such delay, extension or
          termination to the Exchange Agent or (ii) to amend the terms of
          the Exchange Offer in any manner.  Any such delay in acceptances,
          extension, termination or amendment will be followed as promptly
          as practicable by oral or written notice thereof to the


                                     -52-
     


          registered Holders. If the Exchange Offer is amended in a manner
          determined by the Company to constitute a material change, the
          Company will promptly disclose such amendment by means of a
          prospectus supplement that will be distributed to the registered
          Holders, and the Company will extend the Exchange Offer for a
          period of five to ten business days, depending upon the
          significance of the amendment and the manner of disclosure to the
          registered Holders, if the Exchange Offer would otherwise expire
          during such five to ten business day period.

               Without limiting the manner in which the Company may choose
          to make a public announcement of any delay, extension, amendment
          or termination of the Exchange Offer, the Company shall have no
          obligation to publish, advertise, or otherwise communicate any
          such public announcement, other than by making a timely release
          to an appropriate news agency.

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

               In all cases, issuance of the New Notes for Old Notes that
          are accepted for exchange pursuant to the Exchange Offer will be
          made only after timely receipt by the Exchange Agent of a
          properly completed and duly executed Letter of Transmittal and
          all other required documents; provided, however, that the Company
          reserves the absolute right to waive any defects or
          irregularities in the tender or conditions of the Exchange Offer.
          If any tendered Old Notes are not accepted for any reason set
          forth in the terms and conditions of the Exchange Offer or if Old
          Notes are submitted for a greater principal amount, or a greater
          number of shares, respectively, than the Holder desires to
          exchange, then such unaccepted or non-exchanged Old Notes
          evidencing the unaccepted portion, as appropriate, will be
          returned without expense to the tendering Holder thereof as
          promptly as practicable after the expiration or termination of
          the Exchange Offer.

          CONDITIONS

               Notwithstanding any other term of the Exchange Offer, the
          Company will not be required to exchange any New Notes for any
          Old Notes and may terminate the Exchange Offer before the
          acceptance of any Old Notes for exchange, if:

                    (a)  any action or proceeding is instituted or
          threatened in any court or by or before any governmental agency
          with respect to the Exchange Offer which, in the Company's
          reasonable judgment, might materially impair the ability of the
          Company to proceed with the Exchange Offer; or

                    (b)  any law, statute, rule or regulation is proposed,
          adopted or enacted, or any existing law, statute, rule or
          regulation is interpreted by the staff of the Commission, which,
          in the Company's reasonable judgment, might materially impair the
          ability of the Company to proceed with the Exchange Offer; or

                    (c)  any governmental approval or approval by Holders
          of the Old Notes has not been obtained, which approval the
          Company shall, in its reasonable judgment, deem necessary for the
          consummation of the Exchange Offer as contemplated hereby.

               If the Company determines in its sole discretion that any of
          these conditions are not satisfied, the Company may (i) refuse to
          accept any Old Notes and return all tendered Old Notes to the
          tendering Holders, (ii) extend the Exchange Offer and retain all
          Old Notes tendered prior to the expiration of the Exchange Offer,
          subject, however, to the rights of Holders who tendered such Old
          Notes to withdraw their tendered Old Notes or (iii) waive such
          unsatisfied conditions with respect to the Exchange Offer and
          accept all properly tendered Old Notes which have not been


                                     -53-
     


          withdrawn. If such waiver constitutes a material change to the
          Exchange Offer, the Company will promptly disclose such waiver by
          means of a prospectus supplement that will be distributed to the
          registered Holders, and the Company will extend the Exchange
          Offer for a period of five to ten business days, depending upon
          the significance of the waiver and the manner of disclosure to
          the registered Holders, if the Exchange Offer would otherwise
          expire during such five to ten business day period.

          PROCEDURES FOR TENDERING

               To tender in the Exchange Offer, a Holder must complete,
          sign and date the Letter of Transmittal, or facsimile thereof,
          have the signatures thereon guaranteed if required by the Letter
          of Transmittal, and mail or otherwise deliver such Letter of
          Transmittal or such facsimile to the Exchange Agent prior to the
          Expiration Date.  In addition, either (i) certificates for such
          Old Notes must be received by the Exchange Agent along with the
          Letter of Transmittal, or (ii) a timely confirmation of
          book-entry transfer (a "Book-Entry Confirmation") of such Old
          Notes, if such procedure is available, into the Exchange Agent's
          account at the Depository Trust Company (the "Book-Entry Transfer
          Facility") pursuant to the procedure for book-entry transfer
          described below must be received by the Exchange Agent prior to
          the Expiration Date, or (iii) the Holder must comply with the
          guaranteed delivery procedures described below.  To be tendered
          effectively, the Letter of Transmittal and other required
          documents must be received by the Exchange Agent at the address
          set forth below under "--Exchange Agent" prior to the Expiration
          Date.

               The tender by a Holder which is not withdrawn prior to the
          Expiration Date 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.

               THE METHOD OF DELIVERY OF OLD NOTES AND THE LETTER OF
          TRANSMITTAL AND ALL OTHER REQUIRED DOCUMENTS TO THE EXCHANGE
          AGENT IS AT THE ELECTION AND RISK OF THE HOLDER. INSTEAD OF
          DELIVERY BY MAIL, IT IS RECOMMENDED THAT HOLDERS USE AN OVERNIGHT
          OR HAND DELIVERY SERVICE. IN ALL CASES, SUFFICIENT TIME SHOULD BE
          ALLOWED TO ASSURE DELIVERY TO THE EXCHANGE AGENT BEFORE THE
          EXPIRATION DATE. NO LETTER OF TRANSMITTAL OR OLD NOTES SHOULD BE
          SENT TO THE COMPANY. HOLDERS MAY REQUEST THEIR RESPECTIVE
          BROKERS, DEALERS, COMMERCIAL BANKS, TRUST COMPANIES OR NOMINEES
          TO EFFECT THE ABOVE TRANSACTIONS FOR SUCH HOLDERS.

               Any beneficial owner whose Old Notes are registered in the
          name of a broker, dealer, commercial bank, trust company or other
          nominee and who wishes to tender should contact the registered
          Holder promptly and instruct such registered Holder to tender on
          such beneficial owner's behalf. If such beneficial owner wishes
          to tender on such owner's own behalf, such owner must, prior to
          completing and executing the Letter of Transmittal and delivering
          such owner's Old Notes, either make appropriate arrangements to
          register ownership of the Old Notes in such owner's name or
          obtain a properly completed assignment from the registered
          Holder. The transfer of registered ownership may take
          considerable time.

               Signatures on a Letter of Transmittal or a notice of
          withdrawal, as the case may be, must be guaranteed by an Eligible
          Institution (as defined below) unless the Old Notes tendered
          pursuant thereto is tendered (i) by a registered Holder who has
          not completed the box entitled "Special Payment Instructions" or
          "Special Delivery Instructions" on the Letter of Transmittal or
          (ii) for the account of an Eligible Institution (as defined
          below).  In the event that signatures on a Letter of Transmittal
          or a notice of withdrawal, as the case may be, are required to be
          guaranteed, such guarantor must be a member firm of a registered
          national securities exchange or of the National Association of
          Securities Dealers, Inc., a commercial bank or trust company
          having an office or correspondent in the United States or an
          "eligible guarantor institution" within the meaning of Rule
          17Ad-15 under the Exchange Act (an "Eligible Institution").


                                      -54-
     

               If the Letter of Transmittal is signed by a person other
          than the registered Holder of any Old Notes listed therein, such
          Old Notes must be endorsed or accompanied by a properly completed
          bond power signed by such registered Holder as such registered
          Holder's name appears on such Old Notes.

               If the Letter of Transmittal or any Old Notes or bond or
          stock powers 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, evidence satisfactory to the Company of their authority
          to so act must be submitted with the Letter of Transmittal.

               All questions as to the validity, form, eligibility
          (including time of receipt), acceptance of tendered Old Notes and
          withdrawal of tendered Old Notes will be determined by the
          Company in its sole discretion, which determination will be final
          and binding. The Company reserves the absolute right to reject
          any and all Old Notes not properly tendered or any Old Notes the
          Company's acceptance of which would, in the opinion of counsel
          for the Company, be unlawful. The Company also reserves the right
          to waive any defects, irregularities or conditions of tender as
          to particular Old Notes.  The Company's interpretation of the
          terms and conditions of the Exchange Offer (including the
          instructions in the Letter of Transmittal) will be final and
          binding on all parties.  Unless waived, any defects or
          irregularities in connection with tenders of Old Notes must be
          cured within such time as the Company shall determine. Although
          the Company intends to notify Holders of defects or
          irregularities with respect to tenders of Old Notes, none of the
          Company, the Exchange Agent, or any other person shall incur any
          liability for failure to give such notification.  Tenders of Old
          Notes will not be deemed to have been made until such defects or
          irregularities have been cured or waived.  Any Old Notes received
          by the Exchange Agent that are not properly tendered and as to
          which the defects or irregularities have not been cured or waived
          will be returned by the Exchange Agent to the tendering Holders,
          unless otherwise provided in the Letter of Transmittal, as soon
          as practicable following the Expiration Date.

               In addition, the Company reserves the right in its sole
          discretion to purchase or make offers for any Old Notes that
          remain outstanding subsequent to the Expiration Date or, as set
          forth above under "--Conditions," to terminate the Exchange Offer
          and, to the extent permitted by applicable law, purchase Old
          Notes in the open market, in privately negotiated transactions or
          otherwise. The terms of any such purchases or offers could differ
          from the terms of the Exchange Offer.

               By tendering, each Holder will represent to the Company
          that, among other things, (i) the New Notes acquired pursuant to
          the Exchange Offer is being obtained in the ordinary course of
          business of the Person receiving such New Notes, whether or not
          such person is the Holder, (ii) neither the Holder nor any such
          other person is engaging in or intends to engage in a
          distribution of such New Notes, (iii) neither the Holder nor any
          such other person has an arrangement or understanding with any
          Person to participate in the distribution of such New Notes, and
          (iv) neither the Holder nor any such other Person is an
          "affiliate," as defined in Rule 405 of the Securities Act, of the
          Company.

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


                                       -55-
     


          BOOK-ENTRY TRANSFER

               The Exchange Agent each will make a request to establish an
          account with respect to the Old Notes at the Book-Entry Transfer
          Facility for purposes of the Exchange Offer within two business
          days after the date of this Prospectus, and any financial
          institution that is a participant in the Book-Entry Transfer
          Facility's systems may make book-entry delivery of Old Notes by
          causing the Book-Entry Transfer to transfer such Old Notes into
          the Exchange Agent's account at the Book-Entry Transfer Facility
          in accordance with such Book-Entry Transfer Facility's procedures
          for transfer. However, although delivery of Old Notes may be
          effected through book-entry transfer at the Book-Entry Transfer
          Facility, the Letter of Transmittal or facsimile thereof, with
          any required signature guarantees and any other required
          documents, must, in any case, be transmitted to and received by
          the Exchange Agent at the address set forth below under "--
          Exchange Agent" on or prior to the Expiration Date or the
          guaranteed delivery procedures described below must be complied
          with.

          GUARANTEED DELIVERY PROCEDURES

               Holders who wish to tender their Old Notes and (i) whose Old
          Notes are not immediately available or (ii) who cannot deliver
          their Old Notes, the Letter of Transmittal or any other required
          documents to the Exchange Agent prior to the Expiration Date, may
          effect a tender if:

                    (a)  The tender is made through an Eligible
          Institution;

                    (b)  Prior to the Expiration Date, the Exchange Agent
          receives from such Eligible Institution a properly completed and
          duly executed Notice of Guaranteed Delivery (by facsimile
          transmission, mail or hand delivery) setting forth the name and
          address of the Holder, the certificate number(s) of such Old
          Notes and the principal amount of Old Notes tendered stating that
          the tender is being made thereby and guaranteeing that, within
          five New York Stock Exchange trading days after the Expiration
          Date, the Letter of Transmittal (or facsimile thereof) together
          with the certificate(s) representing the Old Notes and any other
          documents required by the Letter of Transmittal will be deposited
          by the Eligible Institution with the Exchange Agent; and 

                    (c)  Such properly completed and executed Letter of
          Transmittal (or facsimile thereof), as well as the certificate(s)
          representing all tendered Old Notes in proper form for transfer
          and other documents required by the Letter of Transmittal are
          received by the Exchange Agent within five New York Stock
          Exchange trading days after the Expiration Date.

               Upon request to the Exchange Agent a Notice of Guaranteed
          Delivery will be sent to Holders who wish to tender their Old
          Notes according to the guaranteed delivery procedures set forth
          above.

          WITHDRAWAL OF TENDERS

               Except as otherwise provided herein, tenders of Old Notes
          may be withdrawn at any time prior to 5:00 p.m., New York City
          time, on the Expiration Date.

               To withdraw a tender of Old Notes in the Exchange Offer, a
          written or facsimile transmission notice of withdrawal must be
          received by the Exchange Agent at its address set forth herein
          prior to 5:00 p.m., New York City time, on the Expiration Date.
          Any such notice of withdrawal must (i) specify the name of the
          person having deposited the Old Notes to be withdrawn (the
          "Depositor"), (ii) identify the Old Notes to be withdrawn
          (including the certificate number or), (iii) be signed by the
          Holder in the same manner as the original signature on the Letter
          of Transmittal by which such Old Notes were tendered (including
          any required signature guarantees) or be accompanied by documents
          of transfer sufficient to have the Trustee with respect to the
          Old Notes register the transfer of such Old Notes in the name of
          the person withdrawing the tender and (iv) specify the name in
          which any such Old Notes are to be registered, if different from
          that of the Depositor. All questions as to the validity, form and


                                    -56-
     


          eligibility (including time of receipt) of such notices will be
          determined by the Company, whose determination shall be final and
          binding on all parties. Any Old Notes so withdrawn will be deemed
          not to have been validly tendered for purposes of the Exchange
          Offer and no New Notes will be issued with respect thereto unless
          the Old Notes so withdrawn are validly retendered. Any Old Notes
          which have been tendered but which are not accepted for payment
          will be returned to the Holder thereof without cost to such
          Holder as soon as practicable after withdrawal, rejection of
          tender or termination of the Exchange Offer. Properly withdrawn
          Old Notes may be retendered by following one of the procedures
          described above under "-- Procedures for Tendering" at any time
          prior to the Expiration Date.

          FEES AND EXPENSES

               The expenses of soliciting tenders will be paid by the
          Company. The principal solicitation is being made by mail;
          however, additional solicitation may be made by telecopier,
          telephone or in person by officers and regular employees of the
          Company and its affiliates.

               The Company has not retained any dealer-manager in
          connection with the Exchange Offer and will not make any payments
          to brokers-dealers or others soliciting acceptances of the
          Exchange Offer. The Company, however, will pay the Exchange Agent
          reasonable and customary fees for their services and will
          reimburse them for their reasonable out-of-pocket expenses in
          connection therewith.

               The cash expenses to be incurred in connection with the
          Exchange Offer will be paid by the Company and are estimated in
          the aggregate to be approximately $100,000. Such expenses include
          registration fees, fees and expenses of the Exchange Agent
          accounting and legal fees and printing costs, among others.

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

                             DESCRIPTION OF THE NEW NOTES

               The New Notes are to be issued under an Indenture, dated as
          of February 12, 1998 (the "Indenture"), between the Company, as
          issuer, and Norwest Bank Colorado, National Association, as
          trustee (the "Trustee"). A copy of the Indenture is available
          upon request from the Company.  The following summary of certain
          provisions of the Indenture does not purport to be complete and
          is subject to, and is qualified in its entirety by reference to,
          all the provisions of the Indenture, including the definitions of
          certain terms therein and those terms made a part thereof by the
          Trust Indenture Act of 1939, as amended (the "Trust Indenture
          Act"). Whenever particular defined terms of the Indenture not
          otherwise defined herein are referred to, such defined terms are
          incorporated herein by reference.  For definitions of certain
          capitalized terms used in the following summary, see "-- Certain
          Definitions."

          GENERAL

               The New Notes will be senior, unsecured obligations of the
          Company, initially limited to $490,000,000 aggregate principal
          amount at maturity, and will mature on February 15, 2008.
          Although for federal income tax purposes, a significant amount of
          original issue discount, taxable as ordinary income, will be
          recognized by a Holder as such discount accrues from the issue
          date of the New Notes, no interest will be payable on the New
          Notes prior to August 15, 2003. From and after February 15, 2003,
          interest will accrue at the rate of 10% per annum from February
          15, 2003, or from the most recent Interest Payment Date to which
          interest has been paid or provided for, payable semiannually (to
          Holders of record at the close of business on the February 1 or
          August 1 immediately preceding the Interest Payment Date) on
          February 15 and August 15 of each year, commencing August 15,
          2003.

               Principal of, premium, if any, and interest on the New Notes
          will be payable, and the New Notes may be exchanged or
          transferred, at the office or agency of the Company (which
          initially will be the corporate trust office of the Trustee at
          1740 Broadway, Denver, Colorado), or at the option of the
          Company, payment of interest may be made by check mailed to the
          Holders at their addresses as they appear in the Security
          Register; provided that all payments of principal, premium, if
          any, and interest with respect to New Notes represented by one or
          more permanent global New Notes registered in the name of or held
          by DTC or its nominee will be made by wire transfer of
          immediately available funds to the accounts specified by the
          Holder or Holders thereof.

               The New Notes will be issued only in fully registered form,
          without coupons, in denominations of $1,000 of principal amount
          at maturity and any integral multiple thereof. See "-- Book
          Entry; Delivery and Form." No service charge will be made for any
          registration of transfer or exchange of New Notes, but the
          Company may require payment of a sum sufficient to cover any
          transfer tax or other similar governmental charge payable in
          connection therewith.

               Subject to the covenants described below under "Covenants"
          and applicable law, the Company may issue additional New Notes
          under the Indenture. The New Notes offered hereby and any
          additional New Notes subsequently issued would be treated as a
          single class for all purposes under the Indenture.

          OPTIONAL REDEMPTION

               The New Notes will be redeemable, at the Company's option,
          in whole or in part, at any time or from time to time, on or
          after February 15, 2003 and prior to maturity, upon not less than
          30 nor more than 60 days' prior notice mailed by first class mail
          to each Holder's last address as it appears in the Security
          Register, at the following prices (the "Redemption Prices")
          (expressed in percentages of principal amount at maturity), plus
          accrued and unpaid interest, if any, 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 an Interest Payment Date), if redeemed
          during the 12-month period commencing February 15, of the years
          set forth below:

           2006 and thereafter . . . . . . . . . . . . . . .    100.0000

               In addition, at any time or from time to time, on or prior
          to February 15, 2001, the Company may, at its option, redeem New
          Notes having an aggregate principal amount at maturity of up to
          35% of the aggregate principal amount at maturity of the Notes
          with the proceeds of one or more public or private Equity
          Offerings, at a Redemption Price equal to 110.0% of Accreted
          Value on the Redemption Date; provided that at least 65% of the
          aggregate principal amount of New Notes initially issued remains
          outstanding after each such redemption.

               In the case of any partial redemption, selection of the New
          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 New Notes are listed or, if the
          New Notes are not listed on a national securities exchange, by
          lot or by such other method as the Trustee in its sole discretion
          shall deem to be fair and appropriate; provided that no New Note
          of $1,000 in principal amount at maturity or less shall be
          redeemed in part. If any New Note is to be redeemed in part only,
          the notice of redemption relating to such New Note shall state
          the portion of the principal amount thereof to be redeemed. A new
          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 New Note.

          RANKING

               The New Notes will be senior, unsecured obligations of the
          Company, will rank pari passu in right of payment with all
          existing and future unsecured, unsubordinated indebtedness and
          will be senior in right of payment to all existing and future
          subordinated indebtedness of the Company. At December 31, 1997,
          after giving pro forma effect to the Private Offering and the
          NETCOM acquisition, the Company would have had, on a consolidated
          basis, approximately $306.6 million of indebtedness including
          capitalized lease obligations. The Company is a holding company
          and the New Notes will be effectively subordinated to all
          liabilities (including trade payables) of the subsidiaries of the
          Company, and at December 31, 1997, on the same pro forma basis,
          the subsidiaries of the Company would have had approximately $-
          34.5 million of liabilities (excluding intercompany payables)
          including approximately $6.0 million of indebtedness, consisting
          solely of capitalized lease obligations. The Company may incur
          substantial amounts of indebtedness in the future. See "Risk
          Factors -- Substantial Indebtedness; Ability to Service Debt" and
          "-- Holding Company Structure; Priority of Creditors."

          CERTAIN DEFINITIONS

               Set forth below is a summary of certain of the defined terms
          used in the covenants and other provisions of the Indenture.
          Reference is made to the Indenture for the definition of any
          other capitalized term used herein for which no definition is
          provided.

               "Accreted Value" is defined to mean, for any Specified Date,
          the amount calculated pursuant to (i), (ii), (iii) or (iv) for
          each $1,000 principal amount at maturity of New Notes:

                    (i) if the Specified Date occurs on one of the
               following dates (each a "Semi-Annual Accrual Date"), the
               Accreted Value will equal the amount set forth below for
               such Semi-Annual Accrual Date:

          application of the proceeds therefrom, the Consolidated Leverage
          Ratio would be greater than zero and less than 6:1.

               Notwithstanding the foregoing, the Company and any
          Restricted Subsidiary (except as specified below) may Incur each
          and all of the following: (i) Indebtedness of the Company or its
          Restricted Subsidiaries outstanding at any time in an aggregate
          principal amount not to exceed (A) $200 million of unsubordinated
          Indebtedness (including any Indebtedness under one or more
          revolving credit or working capital facilities) and (B) $200
          million of subordinated Indebtedness (and any Guarantees thereof
          by the Company or its Restricted Subsidiaries), less any amount
          of such Indebtedness permanently repaid as provided under the
          "Limitation on Asset Sales" covenant described below; (ii) the
          Incurrence by the Company of Indebtedness represented by the New
          Notes; (iii) Indebtedness in existence on the Closing Date; (iv)
          Indebtedness of the Company to a Restricted Subsidiary and
          Indebtedness of a Restricted Subsidiary to the Company or another
          Restricted Subsidiary; provided that such Indebtedness is made
          pursuant to an intercompany note (which, in the case of
          Indebtedness owed to the Company, shall be unsubordinated) and
          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 the Company or another Restricted
          Subsidiary) shall be deemed, in each case, to constitute an
          Incurrence of such Indebtedness not permitted by this clause
          (iv); (v) 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
          clauses (i), (iv), (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 that Indebtedness the proceeds of which are
          used to refinance or refund Indebtedness that is subordinated in
          right of payment to the New Notes shall only be permitted under
          this clause (v) if (A) such new Indebtedness, by its terms or by
          the terms of any agreement or instrument pursuant to which such
          new Indebtedness is issued or remains outstanding, is expressly
          made subordinate in right of payment to the New Notes at least to
          the extent that the Indebtedness to be refinanced is subordinated
          to the New Notes and (B) 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; and provided further that in no event
          may Indebtedness of the Company be refinanced by means of any
          Indebtedness of any Restricted Subsidiary pursuant to this clause
          (v); (vi) 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
          that such agreements (a) are designed solely to protect the
          Company or its Restricted Subsidiaries against fluctuations in
          foreign currency exchange rates or interest rates and (b) do not
          increase the Indebtedness of the obligor outstanding at any time
          (except to the extent Incurred under another clause hereof) other
          than as a result of fluctuations in foreign currency exchange


                                     -72-
     


          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 the
          Company or any of its Restricted Subsidiaries pursuant to such
          agreements, in each case Incurred in connection with the
          disposition of any business, assets or Restricted Subsidiary
          (other than Guarantees of Indebtedness Incurred by any Person
          acquiring all or any portion of such business, assets or
          Restricted Subsidiary for the purpose of financing such
          acquisition), in a principal amount not to exceed the gross
          proceeds actually received by the Company or any Restricted
          Subsidiary in connection with such disposition; (vii)
          Indebtedness of the Company, to the extent the net proceeds
          thereof are promptly (A) used to purchase New Notes tendered in
          an Offer to Purchase made as a result of a Change in Control or
          (B) deposited to defease the New Notes as described below under
          "Defeasance"; (viii) Guarantees of the New Notes and Guarantees
          of Indebtedness of the Company by any Restricted Subsidiary
          provided the Guarantee of such Indebtedness is permitted by and
          made in accordance with the "Limitation on Issuance of Guarantees
          by Restricted Subsidiaries" covenant described below and any
          Guarantee by the Company of Indebtedness or other obligations of
          any of its Restricted Subsidiaries so long as the incurrence of
          such Indebtedness Incurred by such Restricted Subsidiary is
          permitted under the terms of this covenant; (ix) Indebtedness
          Incurred to finance the cost (including, without limitation, the
          cost of design, development, acquisition, construction,

          Person that becomes a Restricted Subsidiary to the extent of the

          so acquired) by the Company or a Restricted Subsidiary after the
          Closing Date; (x) Indebtedness of the Company not to exceed, at
          any one time outstanding, the sum (without duplication) of (A)
          two times the Net Cash Proceeds received by the Company from the
          sale of ICG Common Stock contributed by ICG to the Company after
          the Closing Date to a Person that is not a Subsidiary of the
          Company (1.6 times the closing price, last sale price or similar
          price of such ICG Common Stock at the time received by the
          Company to the extent such ICG Common Stock has not been sold)
          plus (B) two times cash or cash equivalents contributed by ICG or
          its Subsidiaries (other than the Company and its Subsidiaries) to
          the Company after the Closing Date plus (C) 1.6 times the fair
          market value of other assets (including, without limitation,
          Capital Stock) acquired by the Company or its Restricted

          consists of ICG Common Stock plus (D) 1.6 times the fair market
          value of other assets contributed by ICG or its Subsidiaries
          (other than the Company and its Subsidiaries) to the Company
          after the Closing Date plus (E) two times the Net Cash Proceeds
          received by the Company after the Closing Date from the issuance

          times the fair market value of property (other than cash and cash

          the sale of its Capital Stock (other than Disqualified Stock) to
          a Person that is not a Subsidiary of the Company, in each case,
          to the extent such Net Cash Proceeds, ICG Common Stock, cash or
          cash equivalents or such other assets or property have not been
          used pursuant to clause (C)(2) of the first paragraph or clause
          (iii) or (iv), as the case may be, of the second paragraph of the
          "Limitation on Restricted Payments" covenant described below;
          provided that such Indebtedness does not mature prior to the
          Stated Maturity of the New Notes and has a then current Average
          Life at least as long as the New Notes; (xi) Indebtedness
          Incurred by the Company or any of its Restricted Subsidiaries
          constituting reimbursement obligations with respect to letters of

          limitation, letters of credit in respect of workers' compensation
          claims or self insurance, or other Indebtedness with respect to
          reimbursement type obligations regarding workers' compensation
          claims; provided, however, that upon the drawing of such letters
          of credit or the Incurrence of such Indebtedness, such
          obligations are reimbursed within 30 days following such drawing
          or Incurrence; (xii) Acquired Indebtedness or Indebtedness of

          is not incurred in contemplation of such acquisition or merger;
          and (xiii) Strategic Subordinated Indebtedness.


                                      -73-
     


               (b) Notwithstanding any other provision of this "Limitation
          on Indebtedness" covenant, the maximum amount of Indebtedness
          that the Company or a Restricted Subsidiary may Incur pursuant to
          this "Limitation on Indebtedness" covenant shall not be deemed to
          be exceeded, with respect to any outstanding Indebtedness due
          solely to the result of fluctuations in the exchange rates of
          currencies. Accretion on an instrument issued at a discount will
          not be deemed to constitute an Incurrence of Indebtedness.

               (c) For purposes of determining any particular amount of
          Indebtedness under this "Limitation on Indebtedness" covenant,
          (1) 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 and
          (2) any Liens granted pursuant to the equal and ratable
          provisions referred to in the "Limitation on Liens" covenant
          described below shall not be treated as Indebtedness. 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, the Company, 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.

          Limitation on Restricted Payments

               The Company will not, and will not permit any Restricted
          Subsidiary to, directly or indirectly, (i) declare or pay any
          dividend or make any distribution on or with respect to its
          Capital Stock (other than (x) dividends or distributions payable
          solely in shares of its Capital Stock (other than Disqualified
          Stock) or in options, warrants or other rights to acquire shares
          of such Capital Stock and (y) pro rata dividends or distributions
          on common stock of Restricted Subsidiaries held by minority
          stockholders) held by Persons other than the Company or any of
          its Restricted Subsidiaries, (ii) purchase, redeem, retire or
          otherwise acquire for value any shares of Capital Stock of (A)
          the Company or an Unrestricted Subsidiary (including options,
          warrants or other rights to acquire such shares of Capital Stock)
          held by any Person or (B) a Restricted Subsidiary (including
          options, warrants or other rights to acquire such shares of
          Capital Stock) held by any Affiliate of the Company (other than a
          Wholly Owned Restricted Subsidiary), (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 the Company that is subordinated in
          right of payment to the Notes (other than the purchase,
          redemption, repurchase or other acquisition of such subordinated
          Indebtedness purchased in anticipation of satisfying a sinking
          fund obligation, principal installment or final maturity, in each
          case due within six months of the date of acquisition) or (iv)
          make any Investment, other than a Permitted Investment, in any
          Person (such payments or any other actions described in clauses
          (i) through (iv) above 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 making any
          Investments, the Company could not Incur at least $1.00 of
          Indebtedness under the first paragraph of the "Limitation on
          Indebtedness" covenant or (C) the aggregate amount of all
          Restricted Payments (the amount, 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) made 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 the amount of such loss) (determined by excluding
          income resulting from transfers of assets by the Company 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 with the Commission or provided to
          the Trustee pursuant to the "Commission Reports and Reports to
          Holders" covenant plus (2) 100% of (I) the aggregate Net Cash
          Proceeds or fair market value of any Capital Stock and the amount
          of cash from any capital contributions to the Company after the
          Closing Date from Persons other than Subsidiaries of the Company
          (including contributions of ICG Common Stock, cash and cash
          equivalents and other assets to the Company by ICG) plus (II) the
          aggregate Net Cash Proceeds received by the Company after the
          Closing Date from an issuance and sale of its Capital Stock
          (other than Disqualified Stock) to a Person who is not a
          Subsidiary of the Company, including, without limitation, an
          issuance or sale permitted by the Indenture of Indebtedness of


                                      -74-
     


          the Company for cash subsequent to the Closing Date upon the
          conversion of such Indebtedness into Capital Stock (other than
          Disqualified Stock) of the Company, or from the issuance to a
          Person who is not a Subsidiary of the Company of any options,
          warrants or other rights to acquire Capital Stock of the Company
          (in each case, exclusive of any Disqualified 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 New Notes), to the extent such Net
          Cash Proceeds, Capital Stock, marketable securities or amount
          have not been previously applied pursuant to clauses (iii) or
          (iv), as the case may be, of the second paragraph of the
          "Limitation on Restricted Payments" covenant or used to support
          the Incurrence of Indebtedness pursuant to clause (x) under the
          "Limitation of Indebtedness" covenant plus (3) amounts received
          from Investments (other than Permitted Investments) 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 the Company or any Restricted Subsidiary or from the
          Net Cash Proceeds from the sale of any such Investment (except,
          in each case, to the extent any such payment or proceeds are
          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, in each case, the amount of
          Investments previously made by the Company or any Restricted
          Subsidiary in such Person or Unrestricted Subsidiary.

               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 Notes including premium, if any, and accrued and unpaid
          interest, with the proceeds of, or in exchange for, Indebtedness
          Incurred under clause (v) of the second paragraph of part (a) of
          the "Limitation on Indebtedness" covenant; (iii) the making of
          any principal payment or the repurchase, redemption, retirement,
          defeasance or other acquisition for value of Indebtedness of the
          Company which is subordinated in right of payment to the New
          Notes (A) with cash or cash equivalents contributed by ICG to the
          Company after the Closing Date or (B) with, or out of the Net
          Cash Proceeds of, ICG Common Stock or other assets (other than
          cash or cash equivalents) contributed by ICG to the Company after
          the Closing Date, or (C) in exchange for, or out of, the Net Cash
          Proceeds of a substantially concurrent offering of shares of
          Capital Stock (other than Disqualified Stock) of the Company (or
          options, warrants or other rights to acquire such Capital Stock),
          to the extent such Net Cash Proceeds, cash or cash equivalents,
          ICG Common Stock, Capital Stock or such other assets have not
          been used pursuant to clause (C)(2) of the first paragraph or
          clause (iv) of the second paragraph, as the case may be, of the
          "Limitation on Restricted Payments Covenant" or used to support
          the Incurrence of Indebtedness pursuant to clause (x) under the
          "Limitation on Indebtedness Covenant"; (iv) the repurchase,
          redemption or other acquisition of Capital Stock of the Company
          or an Unrestricted Subsidiary (or options, warrants or other
          rights to acquire such Capital Stock) in exchange for, or out of
          the proceeds of a substantially concurrent offering of, shares of
          Capital Stock (other than Disqualified Stock) of the Company (or
          options, warrants or other rights to acquire such Capital Stock);
          or (v) other Restricted Payments in an aggregate amount not to
          exceed $10 million; provided that, except in the case of clauses
          (i), (ii), (iii) and (iv), no Default or Event of Default shall
          have occurred and be continuing or occur as a consequence of the
          actions or payments set forth therein.

               Each Restricted Payment permitted pursuant to the preceding
          paragraph (other than the Restricted Payment referred to in
          clause (ii) thereof) 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.

               Any Restricted Payments made other than in cash shall be
          valued at fair market value. The amount of any Investment
          "outstanding" at any time shall be deemed to be equal to the
          amount of such Investment on the date made, less the return of
          capital to the Company and its Restricted Subsidiaries with
          respect to such Investment by distribution, sale or otherwise (up
          to the amount of such Investment on the date made).

          Limitation on Dividend and Other Payment Restrictions Affecting
          Restricted Subsidiaries

               The Company 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
          the Company or any other Restricted Subsidiary, (ii) pay any
          Indebtedness owed to the Company or any other Restricted
          Subsidiary, (iii) make loans or advances to the Company or any
          other Restricted Subsidiary or (iv) transfer any of its property
          or assets to the Company or any other Restricted Subsidiary.

               The foregoing provisions shall not restrict any encumbrances
          or restrictions: (i) existing on the Closing Date the Indenture
          or any other agreements in effect on the Closing Date, and any
          extensions, refinancings, renewals or replacements of such
          agreements; provided 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, rule, regulation
          or order; (iii) existing with respect to any Person or the
          property or assets of such Person acquired by the Company or any
          Restricted Subsidiary, existing 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, right-of-use, 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 the Company or any Restricted Subsidiary
          not otherwise prohibited by the Indenture, (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 the Company or
          any Restricted Subsidiary in any manner material to the Company
          or any Restricted Subsidiary or (D) purchase money obligations
          (including, without limitation, Capitalized Leases and
          installment sales) for property acquired in the ordinary course
          of business that impose restrictions of the nature discussed in
          clause (iv) above on the property so acquired; (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; (vi) contained in the terms of
          any Indebtedness or any agreement pursuant to which such
          Indebtedness was issued if (A)(1) the encumbrances or
          restrictions apply only in the event of a payment default or a
          default with respect to a financial covenant contained in such
          Indebtedness or agreement or (2) the encumbrances or restrictions
          are similar in nature and substance to the "Limitation on
          Restricted Payments" covenant contained herein, as determined by
          the Board of Directors in good faith, (B) the encumbrances or
          restrictions are not materially more disadvantageous to the
          Holders of the New Notes than is customary in comparable
          financings (as determined by the Company) and (C) the Company
          determines that any such encumbrances or restrictions will not
          materially affect the Company's ability to make principal or
          interest payments on the New Notes; (vii) customary provisions in
          joint venture agreements and other similar agreements entered
          into in the ordinary course of business; and (viii) any
          encumbrances or restrictions of the type referred to in clauses
          (i) through (iv) of the first paragraph of this covenant imposed
          by any amendments, modifications, renewals, restatements,
          increases, supplements, refundings, replacements or refinancings
          of the contracts referred to in clause (i) through (vii) above;
          provided that such amendments, modifications, restatements,
          renewals, increases, supplements, refundings, replacements or
          refinancings are, in the good faith judgment of the Company, not
          materially more disadvantageous to the Holders than those
          contained in the restriction prior to such amendment,
          modification, restatement, renewal, increase, supplement,
          refunding, replacement or refinancing. Nothing contained in this
          "Limitation on Dividend and Other Payment Restrictions Affecting
          Restricted Subsidiaries" covenant shall prevent the Company or
          any Restricted Subsidiary from (1) creating, incurring, assuming
          or suffering to exist any Liens otherwise permitted in the
          "Limitation on Liens" covenant or (2) restricting the sale or
          other disposition of property or assets of the Company or any of
          its Restricted Subsidiaries that secure Indebtedness of the
          Company or any of its Restricted Subsidiaries.

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

               The Company 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 the Company or a Wholly Owned
          Restricted Subsidiary; (ii) issuances of director's qualifying
          shares 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 and any Investment in such
          Person remaining after giving effect to such issuance or sale
          would have been permitted to be made under the "Limitation on
          Restricted Payments" covenant if made on the date of such
          issuance or sale; or (iv) issuances or sales of common stock of a
          Restricted Subsidiary, provided that the Company or any
          Restricted Subsidiary applies an amount equal to the Net Cash
          Proceeds thereof in accordance with the "Limitation on Asset
          Sales" covenant.

          Limitation on Issuances of Guarantees by Restricted Subsidiaries

               The Company will not permit any Restricted Subsidiary,
          directly or indirectly, to Guarantee any Indebtedness of the
          Company which is pari passu with or subordinate in right of
          payment to the New Notes ("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 New 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 the Company or any other
          Restricted Subsidiary as a result of any payment by such
          Restricted Subsidiary under its Subsidiary Guarantee; provided
          that this paragraph shall not be applicable to any Guarantee of
          any Restricted Subsidiary that existed at the time such Person
          became a Restricted Subsidiary and was not Incurred in connection
          with, or in contemplation of, such Person becoming a Restricted
          Subsidiary. If the Guaranteed Indebtedness is (A) pari passu in
          right of payment with the New Notes, then the Guarantee of such
          Guaranteed Indebtedness shall be pari passu in right of payment
          with, or subordinated to, the Subsidiary Guarantee or (B)
          subordinated in right of payment to the New Notes, then the
          Guarantee of such Guaranteed Indebtedness shall be subordinated
          in right of payment to the Subsidiary Guarantee at least to the
          extent that the Guaranteed Indebtedness is subordinated to the
          New Notes.

               Notwithstanding the foregoing, any Subsidiary Guarantee by a
          Restricted Subsidiary may 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 the Company, of all of the Company'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

               The Company 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 Affiliate of the Company or
          any Restricted Subsidiary, except upon fair and reasonable terms
          no less favorable to the Company 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 an Affiliate.


                                     -77-
     


               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
          the Company or a Restricted Subsidiary delivers to the Trustee a
          written opinion of a nationally recognized investment banking
          firm or a nationally recognized firm having expertise in the
          specific area which is the subject of such determination stating
          that the transaction is fair to the Company or such Restricted
          Subsidiary from a financial point of view; (ii) any transaction
          solely between the Company and any of its Restricted Subsidiaries
          or solely between Restricted Subsidiaries; (iii) the payment of
          reasonable and customary regular fees to, and indemnity provided
          on behalf of, officers, directors, employees or consultants of
          the Company or its Restricted Subsidiaries; (iv) any payments or
          other transactions pursuant to any tax-sharing agreement between
          the Company and any other Person with which the Company files a
          consolidated tax return or with which the Company is part of a
          consolidated group for tax purposes; or (v) any Permitted
          Investments and Restricted Payments not prohibited by the
          "Limitation on Restricted Payments" covenant. Notwithstanding the
          foregoing, any transaction or series of related transactions
          covered by the first paragraph of this "Limitation on
          Transactions with Shareholders and Affiliates" covenant and not
          covered by clauses (ii) through (v) of this paragraph the
          aggregate amount of which exceeds $2.0 million in value, must be
          approved or determined to be fair in the manner provided for in
          clause (i) (A) or (B) above.

          Limitation on Liens

               The Company will not, and will not permit any Restricted
          Subsidiary to, create, incur, assume or suffer to exist any Lien
          on any of its assets or properties of any character (including,
          without limitation, licenses), or any shares of Capital Stock or
          Indebtedness of any Restricted Subsidiary, without making
          effective provision for all of the New Notes and all other
          amounts due under the Indenture to be directly secured equally
          and ratably with (or, if the obligation or liability to be
          secured by such Lien is subordinated in right of payment to the
          New Notes, prior to) the obligation or liability secured by such
          Lien.

               The foregoing limitation does not apply to (i) Liens
          existing on the Closing Date or required on the Closing Date to
          be provided in the future; (ii) Liens granted after the Closing
          Date on any assets or Capital Stock of the Company or its
          Restricted Subsidiaries created in favor of the Holders; (iii)
          Liens with respect to the assets of a Restricted Subsidiary
          granted by such Restricted Subsidiary to the Company or a
          Restricted Subsidiary to secure Indebtedness owing to the Company
          or such other Restricted Subsidiary; (iv) Liens securing
          Indebtedness which is Incurred to refinance secured Indebtedness
          which is permitted to be Incurred under clause (v) of the second
          paragraph of the "Limitation on Indebtedness" covenant; provided
          that such Liens do not extend to or cover any property or assets
          of the Company or any Restricted Subsidiary other than the
          property or assets securing the Indebtedness being refinanced;
          (v) Liens on any property or assets of Restricted Subsidiaries
          securing Indebtedness of Restricted Subsidiaries permitted under
          the "Limitation on Indebtedness" covenant; or (vi) Permitted
          Liens.

          Limitation on Sale-Leaseback Transactions

               The Company will not, and will not permit any Restricted
          Subsidiary to, enter into any sale-leaseback transaction
          involving any of its assets or properties whether now owned or
          hereafter acquired, whereby the Company or a Restricted
          Subsidiary sells or transfers such assets or properties and then
          or thereafter leases such assets or properties or any part
          thereof or any other assets or properties which the Company or
          such Restricted Subsidiary, as the case may be, intends to use
          for substantially the same purpose or purposes as the assets or
          properties sold or transferred.

               The foregoing restriction does not apply to any sale-
          leaseback transaction if (i) the lease is for a period, including
          renewal rights, of not in excess of three years; (ii) the lease
          secures or relates to industrial revenue or pollution control
          bonds; (iii) the transaction is solely between the Company and
          any Wholly Owned Restricted Subsidiary or solely between Wholly
          Owned Restricted Subsidiaries; or (iv) the Company or such
          Restricted Subsidiary, within 12 months after the sale or
          transfer of any assets or properties is completed, applies an


                                      -78-
     


          amount not less than the net proceeds received from such sale in
          accordance with clause (A) or (B) of the first paragraph of the
          "Limitation on Asset Sales" covenant described below.

          Limitation on Asset Sales

               The Company will not, and will not permit any Restricted
          Subsidiary to, consummate any Asset Sale, unless (i) the
          consideration received by the Company or such Restricted
          Subsidiary is at least equal to the fair market value of the
          assets sold or disposed of and (ii) at least 75% of the
          consideration received consists of cash or Temporary Cash
          Investments. For purposes of this covenant, the following are
          deemed to be cash: (x) the principal amount or accreted value
          (whichever is larger) of Indebtedness of the Company or any
          Restricted Subsidiary with respect to which the Company or such
          Restricted Subsidiary has either (I) received a written release
          or (II) been released by operation of law, in either case, from
          all liability on such Indebtedness in connection with such Asset
          Sale and (y) securities received by the Company or any Restricted
          Subsidiary from the transferee that are promptly converted by the
          Company or such Restricted Subsidiary into cash. In the event and
          to the extent that the Net Cash Proceeds received by the Company
          or any of its Restricted Subsidiaries from one or more Asset
          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 the Company and its Subsidiaries has been filed
          with the Commission or provided to the Trustee pursuant to the
          "Commission Reports and Reports to Holders" covenant), then the
          Company shall or shall cause the relevant Restricted Subsidiary
          to (i) within 12 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 the Company, or
          any Restricted Subsidiary providing a Subsidiary Guarantee
          pursuant to the "Limitation on Issuances of Guarantees by
          Restricted Subsidiaries" covenant described above or Indebtedness
          of any other Restricted Subsidiary, in each case owing to a
          Person other than the Company 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 12 months after the date
          of such agreement), (x) in property or assets (other than current
          assets) of a nature or type or that are used in a business (or in
          a Person (other than a natural person) 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, the Company 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) or (y) in property or assets
          (other than current assets) related to the Telecommunications
          Business, including, without limitation, telecommunications
          switches and related equipment, services, leases, licenses,
          capacity and rights-of-use, (or in a person (other than a natural
          person) having property or assets related to the
          Telecommunications Business, including, without limitation,
          telecommunications switches and related equipment, services,
          leases, licenses, capacity and rights-of-use) and (ii) apply (no
          later than the end of the 12-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 12-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 $20.0 million, the Company must commence, not
          later than the fifteenth Business Day of such month, and
          consummate an Offer to Purchase from the Holders on a pro rata
          basis, and an offer to purchase any outstanding Indebtedness with
          similar provisions requiring the Company to make an offer to
          purchase such Indebtedness, in an aggregate principal amount at
          maturity of New Notes (or, if prior to February 15, 2003, the
          Accreted Value of the New Notes) and such pari passu Indebtedness
          equal to (A) with respect to the New Notes, the product of such
          Excess Proceeds multiplied by a fraction, the numerator of which
          is the outstanding principal amount at maturity of the New Notes
          (or, if prior to February 15, 2003, the Accreted Value of the New
          Notes) and the denominator of which is the sum of the outstanding


                                      -79-
     


          principal amount at maturity of the New Notes (or, if prior to
          February 15, 2003, the Accreted Value of the New Notes) and such
          pari passu Indebtedness (the product hereinafter referred to as
          the "New Note Amount"), and (B) with respect to the pari passu
          Indebtedness, the excess of the Excess Proceeds over the New Note
          Amount, at a purchase price equal to 100% of the Accreted Value
          of the New Notes or such pari passu Indebtedness, as the case may
          be, on the relevant Payment Date or such other date set forth in
          the documentation governing the pari passu Indebtedness, plus, in
          each case, accrued interest (if any) to the Payment Date or such
          other date set forth in the documentation governing the pari
          passu Indebtedness. If the aggregate purchase price of the New
          Notes tendered pursuant to the Offer to Purchase is less than the
          Excess Proceeds, the remaining will be available for use by the
          Company for general corporate purposes. Upon the consummation of
          any Offer to Purchase in accordance with the terms of the
          Indenture, the amount of Net Cash Proceeds from Asset Sales
          subject to any future Offer to Purchase shall be deemed to be
          zero.

          REPURCHASE OF NEW NOTES UPON A CHANGE OF CONTROL

               The Company must commence, within 30 days of the occurrence
          of a Change of Control, and consummate an Offer to Purchase for
          all New Notes then outstanding, at a purchase price equal to 101%
          of the Accreted Value thereof on the relevant Payment Date, plus
          accrued interest (if any) to the Payment Date.

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

          COMMISSION REPORTS AND REPORTS TO HOLDERS

               Whether or not the Company is required to file reports with
          the Commission, the Company shall deliver for filing with the
          Commission all such reports and other information as it would be
          required to file with the Commission by Sections 13(a) or 15(d)
          under the Securities Exchange Act of 1934 if it were subject

          Commission shall be deemed to refer to the reports then most

          EVENTS OF DEFAULT

               The following events will be defined as "Events of Default"
          in the Indenture: (a) default in the payment of principal of (or
          premium, if any, on) any New Note when the same becomes due and
          payable at maturity, upon acceleration, redemption or otherwise;
          (b) default in the payment of interest on any New Note when the
          same becomes due and payable, and such default continues for a
          period of 30 days; (c) the Company defaults in the performance of
          or breaches any other covenant or agreement of the Company in the
          Indenture or under the New Notes (other than a default specified
          in clause (a) or (b) above) 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 New Notes; (d) the Company shall have failed to
          make or consummate an Offer to Purchase in accordance with the
          "Limitation on Asset Sales" covenant above; (e) the Company shall

          accordance with the provisions of "Repurchase of New Notes upon a
          Change of Control" above; (f) there occurs with respect to any
          issue or issues of Indebtedness of the Company or any Significant
          Subsidiary having an outstanding principal amount of $10 million
          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


                                     -80-
     


          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; (g) any final judgment or order (not covered by
          insurance) for the payment of money in excess of $10 million in
          the aggregate (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 30 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 the Company or any
          of its Significant Subsidiaries to exceed $10 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;
          (h) a court having jurisdiction in the premises enters a decree
          or order for (A) 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, (B) 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 (C) 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 30 consecutive days; or (i) the Company 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 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 (C) effects any general assignment
          for the benefit of creditors.

               If an Event of Default (other than an Event of Default
          specified in clause (h) or (i) 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 New 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 Accreted Value of, premium, if any, and
          accrued interest on the New Notes to be immediately due and
          payable. Upon a declaration of acceleration, such Accreted Value
          of, premium, if any, and accrued interest shall be immediately
          due and payable. In the event of a declaration of acceleration
          because an Event of Default set forth in clause (f) 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 (f)
          shall be remedied or cured by the Company 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
          (h) or (i) above occurs with respect to the Company, the Accreted
          Value of, premium, if any, and accrued interest on the New Notes
          then outstanding shall ipso facto become and be immediately due
          and payable without any declaration or other act on the part of
          the Trustee or any Holder. The Holders of at least a majority in
          principal amount of the outstanding New Notes by written notice
          to the Company and to the Trustee, may waive all past defaults
          and rescind and annul a declaration of acceleration and its
          consequences if (i) all existing Events of Default, other than
          the nonpayment of the Accreted Value of, premium, if any, and
          interest on the New Notes that have become due solely by such
          declaration of acceleration, have been cured or waived and (ii)
          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 New 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

                                     -81-
      


          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 New 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 New 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 New Note
          to receive payment of the principal of, premium, if any, or
          interest on, such New Note or to bring suit for the enforcement
          of any such payment, on or after the due date expressed in the
          New Notes, which right shall not be impaired or affected without
          the consent of the Holder.

               The Indenture will require certain officers of the Company
          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 the Company and its Restricted Subsidiaries and the
          Company's and its Restricted Subsidiaries' performance under the
          Indenture and that the Company 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. The Company will also be obligated to notify
          the Trustee of any default or defaults in the performance of any
          covenants or agreements under the Indenture.

          CONSOLIDATION, MERGER AND SALE OF ASSETS

               The Company will 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 or permit any Person to
          merge with or into the Company unless: (i) the Company shall be
          the continuing Person, or the Person (if other than the Company)
          formed by such consolidation or into which the Company is merged
          or that acquired or leased such property and assets of the
          Company 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 the Company on all of the New 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, (A) the Company or any Person
          becoming the successor obligor of the Notes, as the case may be,
          shall have a Consolidated Net Worth equal to or greater than the
          Consolidated Net Worth of the Company immediately prior to such
          transaction or (B) the Company or any Person becoming the
          successor obligor of the Notes, as the case may be, shall have a
          Consolidated Leverage Ratio no more than the greater of (I) 6:1
          and (II) the Consolidated Leverage Ratio of the Company
          immediately prior to such transaction; provided that this clause
          (iii) shall not apply to a consolidation or merger with or into a
          Wholly Owned Restricted Subsidiary with a positive net worth;
          provided that, in connection with any such merger or
          consolidation, no consideration (other than Capital Stock (other
          than Disqualified Stock) in the surviving Person or the Company)
          shall be issued or distributed to the stockholders of the
          Company; and (iv) the Company delivers to the Trustee an
          Officers' Certificate (attaching the arithmetic computations to
          demonstrate compliance with clause (iii) above) 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 clause (iii) above does not apply if, in the good
          faith determination of the Board of Directors of the Company,
          whose determination shall be evidenced by a Board Resolution, the
          principal purpose of such transaction is to change the state of
          incorporation of the Company; and that any such transaction shall
          not have as one of its purposes the evasion of the foregoing
          limitations.

          DEFEASANCE

               Defeasance and Discharge. The Indenture will provide that
          the Company will be deemed to have paid and will be discharged
          from any and all obligations in respect of the New Notes on the


                                     -82-
     

      
          123rd day after the deposit referred to below, and the provisions
          of the Indenture will no longer be in effect with respect to the
          New Notes (except for, among other matters, certain obligations
          to register the transfer or exchange of the New Notes, to replace
          stolen, lost or mutilated New Notes, to maintain paying agencies
          and to hold monies for payment in trust) if, among other things,
          (A) the Company 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 New
          Notes on the Stated Maturity of such payments in accordance with
          the terms of the Indenture and the New Notes, (B) the Company 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 the Company'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 Closing 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 United States
          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 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 the Company or any of its
          Subsidiaries is a party or by which the Company or any of its
          Subsidiaries is bound and (D) if at such time the New Notes are
          listed on a national securities exchange, the Company has
          delivered to the Trustee an Opinion of Counsel to the effect that
          the New Notes will not be delisted as a result of such deposit,
          defeasance and discharge, provided that if simultaneously with
          the deposit of the money and/or U.S. Government Obligations
          referred to in (A) above, the Company has caused an irrevocable,
          transferrable, standby letter of credit to be issued by a bank
          with capital and surplus exceeding the principal amount of the
          New Notes then outstanding, expiring not earlier than 180 days
          from its issuance, in favor of the Trustee which permits the
          Trustee to draw an amount equal to the principal, premium, if
          any, and accrued interest on the New Notes through the expiry
          date of the letter of credit, then the Company will be deemed to
          have paid and discharged any and all obligations in respect of
          the New Notes on the date of the deposit and issuance of the
          letter of credit.

               Defeasance of Certain Covenants and Certain Events of
          Default. The Indenture further will provide that the provisions
          of the Indenture will no longer be in effect with respect to
          clause (iii) 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 other covenants
          and clauses (c), (d), (e), (f) and (g) under "Events of Default"
          shall be deemed not to be Events of Default 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 New Notes on the
          Stated Maturity of such payments in accordance with the terms of
          the Indenture and the New Notes, the satisfaction of the
          provisions described in clauses (B)(ii), (C) and (D) of the
          preceding paragraph and the delivery by the Company 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
          the Company exercises its option to omit compliance with certain
          covenants and provisions of the Indenture with respect to the New
          Notes as described in the immediately preceding paragraph and the
          New Notes are declared due and payable because of the occurrence


                                      -83-
     


          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 New Notes at
          the time of their Stated Maturity but may not be sufficient to
          pay amounts due on the New Notes at the time of the acceleration
          resulting from such Event of Default. However, the Company will
          remain liable for such payments.

          MODIFICATION AND WAIVER

               Modifications and amendments of the Indenture may be made by
          the Company and the Trustee with the consent of the Holders of
          not less than a majority in aggregate principal amount of the
          outstanding New 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 New Note, (ii) reduce
          the Accreted Value or principal amount of, or premium, if any, or
          interest on, any New Note, (iii) change the place or currency of
          payment of principal of, or premium, if any, or interest on, any
          New 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 New Note, (v) reduce the above-stated percentage of
          outstanding New 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 New
          Notes or (vii) reduce the percentage or aggregate principal
          amount of outstanding New Notes the consent of whose Holders is
          necessary for waiver of compliance with certain provisions of the
          Indenture or for waiver of certain defaults.

          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 New
          Notes or for any claim based thereon or otherwise in respect
          thereof, and no recourse under or upon any obligation, covenant
          or agreement of the Company in the Indenture, or in any of the
          New 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
          the Company or of any successor Person thereof. Each Holder, by
          accepting the New 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 Holdings or
          the Guarantor, 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 it
          acquires any conflicting interest, it must eliminate such
          conflict or resign. 

          BOOK ENTRY; DELIVERY AND FORM

               All of the Old Notes were originally issued in the form of
          one Global Note (the "Global Old Note").  The Global Old Note was
          deposited upon issuance with the Trustee as custodian for, and
          registered in the name of a nominee of, The Depository Trust
          Company ("DTC"), in New York, New York.  The New Notes will be
          issued in the form of one Global Note (the "Global New Note") and
          deposited upon issuance with and registered in the name of, or on
          behalf of, DTC or its nominee.

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

               Payments of the principal of, and interest on, a Global New
          Note will be made to DTC or its nominee, as the case may be, as
          the registered owner thereof. Neither the Company, the Trustee
          nor any Paying Agent will have any responsibility or liability
          for any aspect of the records relating to or payments made on
          account of beneficial ownership interests in a Global New Note or
          for maintaining, supervising or reviewing any records relating to
          such beneficial ownership interests.

               The Company expects that DTC or its nominee, upon receipt of
          any payment of principal or interest in respect of a Global New
          Note, will credit participants' accounts with payments in amounts
          proportionate to their respective beneficial interests in the
          principal amount of such Global New Note as shown on the records
          of DTC or its nominee. The Company also expects that payments by
          participants to owners of beneficial interests in such Global New
          Note held through such participants will be governed by standing
          instructions and customary practices, as is now the case with
          securities held for the accounts of customers registered in the
          names of nominees for such customers. Such payments will be the
          responsibility of such participants.

               Transfers between participants in DTC will be effected in
          the ordinary way in accordance with DTC rules and will be settled
          in same-day funds. Transfers between participants in Euroclear &
          Cedel Bank will be effected in the ordinary way in accordance
          with their respective rules and operating procedures.

               New Notes that are issued as described below will be issued
          in the form of registered definitive certificates (the
          "Certificated New Notes"). Such Certificated New Notes may,
          unless the applicable Global New Note has previously been
          exchanged for Certificated New Notes, be exchanged for an
          interest in the applicable Global New Note representing the
          principal amount of Old Notes being transferred.

               The Company expects that DTC will take any action permitted
          to be taken by a holder of New Notes (including the presentation
          of New Notes for exchange as described below) only at the
          direction of one or more participants to whose account the DTC
          interests in a Global New Note is credited and only in respect of
          such portion of the aggregate principal amount of New Notes as to
          which such participant or participants has or have given such
          direction. However, if there is an Event of Default under the New
          Notes, DTC will exchange the applicable Global New Note for
          Certificated New Notes, which it will distribute to its
          participants and which may be legended as set forth under the
          heading "Transfer Restrictions."


                                     -85-
     


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

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

               If DTC is at any time unwilling or unable to continue as a
          depositary for the Global New Notes and a successor depositary is
          not appointed by the Company within 90 days, the Company will
          issue Certificated New Notes, which may bear the legend referred
          to under "Transfer Restrictions," in exchange for the Global New
          Notes. Holders of an interest in a Global New Note may receive
          Certificated New Notes, which may bear the legend referred to
          under "Transfer Restrictions," in accordance with the DTC's rules
          and procedures in addition to those provided for under the
          Indenture.

               CERTAIN UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

               The following summary describes the material anticipated
          federal income tax consequences of the purchase, ownership and
          disposition of the New Notes. Except where noted, this summary
          deals only with New Notes held as capital assets within the
          meaning of Section 1221 of the Internal Revenue Code of 1986, as
          amended (the "Code"), by United States Holders (as defined
          below), and does not deal with special situations, such as those
          of dealers in securities or currencies, financial institutions,
          life insurance companies, tax exempt organizations, persons
          holding New Notes as a part of a hedging or conversion
          transaction or a straddle or United States Holders whose
          "functional currency" is not the U.S. dollar. Furthermore, the
          discussion below is based upon the provisions of the Code and
          Treasury regulations, administrative and judicial decisions
          thereunder as of the date hereof, and such authorities may be
          repealed, revoked or modified with possible retroactive effect so
          as to result in federal income tax consequences different from
          those discussed below. ALL PROSPECTIVE PURCHASERS ARE ADVISED TO
          CONSULT THEIR OWN TAX ADVISORS REGARDING THE FEDERAL, STATE,
          LOCAL AND FOREIGN TAX CONSEQUENCES OF THE PURCHASE, OWNERSHIP AND
          DISPOSITION OF THE NEW NOTES.

          TAX CONSEQUENCES TO UNITED STATES HOLDERS

               As used herein, a "United States Holder" means a beneficial
          owner that is a citizen or resident of the United States, a
          corporation, partnership or other entity created or organized in
          or under the laws of the United States or any political
          subdivision thereof, an estate the income of which is subject to
          United States federal income taxation regardless of its source,
          or a trust the administration of which is subject to the primary
          supervision of a court within the United States and for which one
          or more U.S. persons have the authority to control all
          substantial decisions. An individual may, subject to certain
          exceptions, be deemed to be a resident (as opposed to a non-
          resident alien) of the United States by virtue of being present
          in the United States on at least 31 days in the calendar year and
          for an aggregate of at least 183 days during a three-year period
          ending in the current calendar year (counting for such purposes
          all of the days present in the current year, one-third of the
          days present in the immediately preceding year, and one-sixth of
          the days present in the second preceding year). A "Non-United
          States Holder" is a holder that is not a United States Holder.

          Exchange of Old Notes for New Notes

               The exchange of an Old Note by a United States Holder for a
          New Note should not constitute a taxable exchange. A United
          States Holder will have the same tax basis and holding period in
          the New Note as such Holder did in the Old Note. In addition, a
          United States Holder will have the same OID, market discount and
          acquisition premium (as described below) in the New Note as such
          Holder had in the Old Note.

          Payments of Interest on the New Notes

               The stated interest on a New Note will not be treated as
          interest for federal income tax purposes, but instead will be
          subject to the original issue discount ("OID") rules described
          below. Payments of stated interest on a New Note will not be
          separately included in income, but rather will be treated first
          as payments of previously accrued OID and then as payments of
          principal and consequently will reduce a United States Holder's
          basis in a New Note as described below under "-- Sale, Exchange
          or Redemption of New Notes."

          Original Issue Discount

               The New Notes are being issued with OID. The excess of a New
          Note's "stated redemption price at maturity" over its "issue
          price" will generally constitute OID for federal income tax
          purposes. The "issue price" of a debt instrument issued for cash
          is equal to the first price at which a substantial amount of such
          debt instruments are sold (excluding sales to bond houses and
          brokers). 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


                                     -87-
     


          stated interest" (defined generally as stated interest that is
          unconditionally payable in cash or in property (other than the
          debt instruments of the issuer), at least annually at a single
          fixed rate that appropriately takes into account the length of
          intervals between payments).

               Because interest on the New Notes is not payable until
          August 15, 2003, the stated interest on the New Notes will not be
          treated as qualified stated interest. In addition, the New Notes
          are being issued at a price that is less than their stated
          principal amount. As a result, the New Notes will be treated as
          issued with OID equal to the excess of their stated redemption
          price at maturity (which will be equal to the sum of the
          principal amount plus all payments of stated interest) over their
          issue price.

               United States Holders of the New Notes should be aware that
          they generally must include OID in gross income for federal
          income tax purposes on an annual basis under a constant yield
          accrual method, regardless of their method of accounting. As a
          result, United States Holders will include OID in income in
          advance of the receipt of cash attributable to that income.
          However, United States Holders of New Notes generally will not be
          required to include separately in income cash interest payments
          received on the New Notes. The Company will report to United
          States Holders of New Notes on a timely basis the reportable
          amount of OID based on its understanding of applicable law.

               The amount of OID includible in income by the initial United
          States Holder of a New Note is the sum of the "daily portions" of
          OID with respect to the New Note for each day during the taxable
          year or portion of the taxable year in which such United States
          Holder held such New Note. The daily portion is determined by
          allocating to each day in any "accrual period" a pro rata portion
          of the OID allocable to that accrual period. The "accrual period"
          for a New Note may be of any length and may vary in length over
          the term of the New Note, provided that each accrual period is no
          longer than one year and each scheduled payment of principal or
          interest occurs on the first day or the final day of an accrual
          period. The amount of OID allocable to any accrual period is an
          amount equal to the excess, if any, of (a) the product of the New
          Note's adjusted issue price at the beginning of such accrual
          period and its yield to maturity (determined on the basis of
          compounding at the close of each accrual period and properly
          adjusted for the length of the accrual period) over (b) the
          amount of any qualified stated interest allocable to the accrual
          period. OID allocable to a final accrual period is the difference
          between the amount payable at maturity (other than a payment of
          qualified stated interest) and the adjusted issue price at the
          beginning of the final accrual period. The yield of a New Note
          is, rounded to two decimal places, 10.00%. The "adjusted issue
          price" of a New Note at the beginning of any accrual period is
          equal to its issue price increased by the accrued OID for each
          prior accrual period (determined without regard to the
          amortization of any acquisition or bond premium, as described
          below) and reduced by any payments made on such New Note (other
          than qualified stated interest) on or before the first day of the
          accrual period.

               The New Notes may be redeemed prior to their Stated Maturity
          at the option of the Company. For purposes of computing the yield
          of such instrument, the Company will be deemed to exercise or not
          exercise its option to redeem the New Notes in a manner that
          minimizes the yield on the New Notes. It is not anticipated that
          the Company's ability to redeem prior to stated maturity will
          affect the yield of the New Notes. Consequently, the Company does
          not intend to treat the redemption option as affecting the
          computation of the yield to maturity of the New Notes.

               In the event of a change of control, the Company will be
          required to offer to repurchase all of the New Notes. The right
          of holders to require repurchase upon a Change of Control will
          not affect the yield or maturity date of the New Notes provided
          that, based on all the facts and circumstances as of the issue
          date, the payment schedule on such New Notes that does not
          reflect a change of control is significantly more likely than not
          to occur. The Company does not intend to treat the change of
          control provisions of the New Notes as affecting the computation
          of the yield to maturity of the New Notes.


                                     -88-
     


          Market Discount

               With respect to a United States Holder who purchased an Old
          Note at original issuance, such instrument, and, accordingly, a
          New Note held by such holder, will not be treated as issued with
          "market discount" for federal income tax purposes unless the Old
          Note was purchased for less than its issue price and the
          difference between the purchase price and the issue price is
          greater than a specified de minimis amount. With respect to a
          subsequent United States Holder who purchased an Old Note or who
          purchases a New Note, such Note will not be treated as issued
          with market discount for federal income tax purposes unless such
          Note was purchased for less than its stated redemption price at
          maturity and the difference between the purchase price and the
          stated redemption price at maturity is greater than a specified
          de minimis amount. Under the market discount rules, a United
          States Holder holding a Note with market discount will be
          required to treat any principal payment on an Old Note or a New
          Note, or any gain on the sale, exchange, retirement or other
          disposition of such Note, 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 Note at the time of such
          payment or disposition. In addition, the United States Holder may
          be required to defer, until the maturity of such Note or its
          earlier disposition in a taxable transaction, the deduction of
          all or a portion of the interest expense on any indebtedness
          incurred or continued to purchase or carry such Note.

               Any market discount will be considered to accrue ratably
          during the period from the date of acquisition to the maturity
          date of such Note, unless the United States Holder elects to
          accrue on a constant interest rate method. A United States Holder
          of Note may elect to include market discount in income currently
          as it accrues (on either a ratable or constant interest rate
          method), in which case the rule described above regarding
          deferral of interest deductions 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
          taxable year to which the election applies and may not be revoked
          without the consent of the IRS.

          Acquisition Premium

               A United States Holder that purchases a New Note for an
          amount that is greater than its adjusted issue price but equal to
          or less than the sum of all amounts payable on the New Note after
          the purchase date, will be considered to have purchased such New
          Note at an "acquisition premium." Under the acquisition premium
          rules, the amount of OID, if any, which such United States Holder
          must include in its gross income with respect to such New Note
          for any taxable year will be reduced by the portion of such
          acquisition premium properly allocable to such year.

          Sale, Exchange or Redemption of New Notes

               Upon the sale, exchange or redemption of a New Note, a
          United States Holder will recognize gain or loss equal to the
          difference between the amount realized upon the sale, exchange or
          redemption and such United States Holder's adjusted tax basis of
          the New Note. A United States Holder's tax basis in a New Note
          will, in general, be the United States Holder's cost therefor,
          increased by OID and market discount previously included in
          income by the United States Holder with respect to the New Notes
          and reduced by any principal and stated interest payments on the
          New Notes. Such gain or loss will be capital gain or loss.

               The Taxpayer Relief Act of 1997 includes substantial changes
          to the federal taxation of capital gains recognized by certain
          noncorporate taxpayers, such as individuals, including a 20%
          maximum tax rate for certain gains from the sale of capital
          assets held for more than 18 months. The deduction of capital
          losses is subject to certain limitations.


                                     -89-
     


          Information Reporting and Backup Withholding

               In general, information reporting requirements will apply to
          certain payments of principal and OID and to the proceeds of
          sales of New Notes made to United States Holders other than
          certain exempt recipients (such as corporations). A 31% backup
          withholding tax will apply to such payments if the United States
          Holder (i) fails to provide a taxpayer identification number,
          (ii) furnishes an incorrect TIN, (iii) is notified by the
          Internal Revenue Service ("IRS") that it has failed to properly
          report payments of interest and dividends or (iv) under certain
          circumstances, fails to certify, under penalty of perjury, that
          it has furnished a correct TIN and has not been notified by the
          IRS that it is subject to backup withholding. In the case of
          interest paid after December 31, 1999, a United States Holder
          generally will be subject to backup withholding at a 31% rate
          unless certain IRS certification procedures are complied with
          directly or through an intermediary.

               The Company will furnish annually to the IRS and to record
          holders of the New Notes (other than with respect to certain
          exempt holders) information relating to the OID accruing during
          the calendar year. The annual accruals of OID included in such
          information will be based on the amount of OID that would have
          accrued to a United States Holder who acquired the Old Note at
          original issue.

               Any amounts withheld under the backup withholding rules will
          be allowed as a refund or a credit against such United States
          Holder's U.S. federal income tax liability provided the required
          information is furnished to the IRS.

          TAX CONSEQUENCES TO NON-UNITED STATES HOLDERS

          Interest and OID on New Notes

               Subject to the discussion below concerning backup
          withholding, no withholding of United States federal income tax
          will be required with respect to the payment by the Company or
          any paying agent of principal or interest (which for purposes of
          this discussion includes OID) on a New Note owned by a Non-United
          States Holder, provided that the beneficial owner (i) 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 within the meaning of Section 871(h)(3) of the Code and the
          regulations thereunder, (ii) is not a controlled foreign
          corporation related, directly or indirectly, to the Company
          through stock ownership, (iii) is not a bank whose receipt of
          interest on a New Note is described in Section 881(c)(3)(A) of
          the Code and (iv) satisfies the statement requirement (described
          generally below) set forth in Section 871(h) and Section 881(c)
          of the Code and the regulations thereunder.

               To satisfy the requirement referred to in (iv) above, the
          beneficial owner of such New Note, or a financial institution
          holding the New Note on behalf of such owner, must provide, in
          accordance with specified procedures, the Company or its paying
          agent with a statement to the effect that the beneficial owner is
          not a U.S. person. These requirements will be met if (1) the
          beneficial owner provides his name and address, and certifies,
          under penalties of perjury, that he is not a U.S. person (which
          certification may be made on an IRS Form W-8 (or successor form))
          or (2) a financial institution holding the New Note on behalf of
          the beneficial owner certifies, under penalties of perjury, that
          such statement has been received by it and furnishes a paying
          agent with a copy thereof.

               In the event that any of the above requirements are not
          satisfied, the Company will nonetheless not withhold federal
          income tax on interest paid to or accrued by a Non-United States
          Holder if it receives IRS Form 4224 (or, after December 31, 1999,
          a Form W-8) from that Non-United States Holder, establishing that
          such income is effectively connected with the conduct of a trade
          or business in the United States, unless the Company has
          knowledge to the contrary. Interest (including OID) paid to a
          Non-United States Holder (other than a partnership) that is
          effectively connected with the conduct by the holder of a trade
          or business in the United States is generally taxed at the
          graduated rates that are applicable to United States persons. In
          the case of a Non-United States Holder that is a corporation,
          such effectively connected income may also be subject to the


                                      -90-
     


          United States federal branch profits tax (which is generally
          imposed on a foreign corporation on the deemed repatriation from
          the United States of effectively connected earnings and profits)
          at a 30% rate (unless the rate is reduced or eliminated by an
          applicable income tax treaty and the holder is a qualified
          resident of the treaty country). Special rules may apply to
          interest paid to or accrued by a partnership with foreign
          partners (i.e., persons who would be Non-United States Holders if
          they held the New Notes directly).

          Sale, Exchange or Redemption of New Notes

               A Non-United States Holder will generally not be subject to
          United States federal income tax with respect to gain recognized
          on a sale, exchange or redemption of New Notes unless (i) the
          gain is effectively connected with a trade or business of the
          Non-United States Holder in the United States, (ii) in the case
          of a Non-United States Holder who is an individual and holds the
          New Notes as a capital asset, such holder is present in the
          United States for 183 or more days in the taxable year of the
          sale or other disposition and certain other conditions are met,
          or (iii) the Non-United States Holder is subject to tax pursuant
          to certain provisions of the Code applicable to United States
          expatriates.

               Gains derived by a Non-United States Holder (other than a
          partnership) from the sale or other disposition of New Notes that
          are effectively connected with the conduct by the Holder of a
          trade or business in the United States are generally taxed at the
          graduated rates that are applicable to United States persons. In
          the case of a Non-United States Holder that is a corporation,
          such effectively connected income may also be subject to the
          United States branch profits tax. If an individual Non-United
          States Holder falls under clause (ii) above, he will be subject
          to a flat 30% tax on the gain derived from the sale or other
          disposition, which may be offset by United States capital losses
          recognized within the same taxable year as such sale or other
          disposition (notwithstanding the fact that he is not considered a
          resident of the United States). Special rules may apply to the
          sale, exchange or redemption of New Notes by partnerships with
          foreign partners (i.e., persons who would be Non-United States
          Holders if they held the New Notes directly).

          Federal Estate Tax

               A New Note beneficially owned by an individual who at the
          time of death is a Non-United States Holder will not be subject
          to United States federal estate tax as a result of such
          individual's death, provided that such individual 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 within the meaning of Section 871(h)(3) of the Code and
          provided that the interest payments with respect to such New Note
          would not have been, if received at the time of such individual's
          death, effectively connected with the conduct of a United States
          trade or business by such individual.

          Information Reporting and Backup Withholding

               No information reporting or backup withholding will be
          required with respect to payments made by the Company or any
          paying agent to Non-United States Holders if a statement
          described in (iv) under "Tax Consequences to Non-United States
          Holders -- Interest and OID on New Notes" has been received and
          the payor does not have actual knowledge that the beneficial
          owner is a United States person.

               Information reporting and backup withholding will not apply
          if payments of OID on a New Note are paid or collected by a
          custodian, nominee, or agent on behalf of the beneficial owner of
          such New Note if such custodian, nominee, or agent has
          documentary evidence in its records that the beneficial owner is
          not a U.S. person and certain other conditions are met, or the
          beneficial owner otherwise establishes an exemption.

               Payments on the sale, exchange or other disposition of a New
          Note made to or through a foreign office of a broker generally
          will not be subject to backup withholding. However, if the broker
          is a United States person, a controlled foreign corporation for
          United States federal income tax purposes, a foreign person 50


                                     -91-
     


          percent or more of whose gross income is effectively connected
          with a United States trade or business for a specified three year
          period, or (with respect to payments after December 31, 1999) a
          foreign partnership with certain connections to the United
          States, such payments will be subject to information reporting
          unless the broker has in its records documentary evidence that
          the beneficial owner is not a United States person and certain
          other conditions are met, or the beneficial owner otherwise
          establishes an exemption. Backup withholding may apply to any
          payment that such broker is required to report if the broker has
          actual knowledge that the payee is a United States person.
          Payments to or through the United States office of a broker will
          be subject to information reporting and backup withholding unless
          the Non-United States Holder certifies, under penalties of
          perjury, that it is not a United States person or otherwise
          establishes an exemption.

               For payments made after December 31, 1999, with respect to
          New Notes held by foreign partnerships, IRS regulations require
          that the certification described in (iv) under "Interest and OID
          on New Notes" above be provided by the partners, rather than by
          the foreign partnership, and that the partnership provide certain
          information, including a United States taxpayer identification
          number. A look-through rule will apply in the case of tiered
          partnerships.

               Non-United States Holders should consult their tax advisors
          regarding the application of information reporting and backup
          withholding in their particular situations, the availability of
          an exemption therefrom, and the procedures for obtaining such an
          exemption, if available. Any amounts withheld under the backup
          withholding rules will be allowed as a refund or credit against
          the Non-United States Holder's U.S. federal income tax liability
          and may entitle such Holder to a refund, provided the required
          information is furnished to the IRS.


                                      -92-
     


                              PLAN OF DISTRIBUTION 

               Except as described below, a broker-dealer may not
          participate in the Exchange Offer in connection with a
          distribution of the New Notes. Each broker-dealer that receives
          New Notes for its own account pursuant to the Exchange Offer must
          acknowledge that it will deliver a prospectus in connection with
          any resale of such New Notes. This Prospectus, as it may be
          amended or supplemented from time to time, may be used by a
          broker-dealer in connection with resales of New Notes received in
          exchange for Old Notes where such Old Notes were acquired as a
          result of market-making activities or other trading activities.
          The Company shall for a period of 90 days after the Expiration
          Date 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 the Exchange Offer may be sold
          from time to time in one or more transactions in the
          over-the-counter market, in negotiated transactions, through the
          writing of options on the New Notes or a combination of such
          methods of resale, at market prices prevailing at the time of
          resale, at prices related to such prevailing market prices or
          negotiated prices. Any such resale may be made directly to
          purchasers or to or through brokers or dealers who may receive
          compensation in the form of commissions or concessions from any
          such broker-dealer and/or the purchasers of any such New Notes.
          Any broker-dealer that resells New Notes that were received by it
          for its own account pursuant to the Exchange Offer and any broker
          or dealer that participates in a distribution of such New Notes
          may be deemed to be an "underwriter" within the meaning of the
          Securities Act and any profit on any such resale of New Notes and
          any commissions or concessions received by any such persons may
          be deemed to be underwriting compensation under the Securities
          Act. The Letter of Transmittal states that by acknowledging that
          it will deliver and by delivering a prospectus, a broker-dealer
          will not be deemed to admit that it is an "underwriter" within
          the meaning of the Securities Act.

               The Company has agreed to pay all expenses incident to the
          Exchange Offer other than commissions or concessions of any
          brokers or dealers and expenses of counsel for the holders of the
          New Notes and will indemnify the holders of the New Notes
          (including any broker-dealers) against certain liabilities,
          including liabilities under the Securities Act.


                                    LEGAL MATTERS

               The validity of the New Notes offered hereby and certain tax
          matters will be passed upon by Reid & Priest LLP, New York, New
          York.

                  REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS


          The Board of Directors and Stockholders
          NETCOM On-Line Communication Services, Inc.

               We have audited the accompanying consolidated balance sheets
          of NETCOM On-Line Communication Services, Inc. as of December 31,
          1996 and 1997, and the related consolidated statements of
          operations, stockholders' equity and cash flows for each of the
          three years in the period ended December 31, 1997.  These
          financial statements are the responsibility of the Company's
          management.  Our responsibility is to express an opinion on these
          financial statements based on our audits.

               We conducted our audits in accordance with generally
          accepted auditing standards.  Those standards require that we
          plan and perform the audit to obtain reasonable assurance about
          whether the financial statements are free of material
          misstatement.  An audit includes examining, on a test basis,
          evidence supporting the amounts and disclosures in the financial
          statements.  An audit also includes assessing the accounting
          principles used and significant estimates made by management, as
          well as evaluating the overall financial statement presentation. 
          We believe that our audits provide a reasonable basis for our
          opinion.

               In our opinion, the consolidated financial statements
          referred to above present fairly, in all material respects, the
          consolidated financial position of NETCOM On-Line Communication
          Services, Inc. at December 31, 1996 and 1997 and the consolidated
          results of its operations and its cash flows for each of the
          three years in the period ended December 31, 1997, in conformity
          with generally accepted accounting principles.

                      NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


          NOTE 1   ORGANIZATION

           NETCOM On-Line Communication Services, Inc. ("NETCOM" or the
          "Company") was incorporated in the state of California in August
          1992.  In October 1994, the Company reincorporated in the state
          of Delaware.  The Company provides Internet solutions to
          subscribers in the United States, the United Kingdom and Canada. 
          On January 21, 1998, the Company became a wholly owned subsidiary
          of ICG Services, Inc., a Delaware Corporation, which is a wholly
          owned subsidiary of ICG Communications, Inc. and ceased to exist
          as an independent entity (see note 11).

          NOTE 2   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

           Principles of Consolidation

           The consolidated financial statements include the accounts of
          the Company and its subsidiaries.  All significant intercompany
          accounts and transactions have been eliminated.  Investments in
          affiliated companies representing less than a 20% interest and
          for which there is no ability to exert significant influence are
          carried at cost.

           Estimates and Assumptions

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

           Revenue Recognition

           Monthly subscription service revenue is recognized over the
          period services are provided.  Subscription service and equipment
          revenue, which require the use of Company-provided installation
          of equipment at a subscriber's location, are recognized when the
          service is commenced.

           Cash and Cash Equivalents

           The Company considers all highly liquid investments with an
          original maturity (at the date of purchase) of three months or
          less and insignificant interest rate risk to be the equivalent of
          cash for the purposes of the balance sheet presentation and
          statement of cash flows.

           Accounts Receivable and Deferred Revenue

           The Company generally bills for subscription service, including
          direct access, Web site hosting and dial-up connection services
          and initial one-time setup fees, on the first day of each month
          for which service is provided.  Deferred revenue consists
          primarily of prepaid monthly subscriptions and also, to a lesser
          extent, billings to customers for equipment shipped that has not
          been installed at customer locations.

           Inventory

           Inventory consists of purchased goods and is stated at the
          lower of cost or market on a first-in, first-out basis.


                                     F-7
     


           Property and Equipment

           Property and equipment are carried at cost and depreciated or
          amortized using the straight-line method over the estimated
          useful life of the assets, which is generally three to five
          years. Leasehold improvements are amortized by the straight-line
          method over the shorter of their estimated useful lives or the
          term of the related lease.  Equipment under capital leases is
          depreciated on a straight-line basis over lease terms of thirty-
          six months.

           Deferred Subscriber Acquisition Costs

           The Company expenses the costs of advertising as incurred,
          except direct response advertising, which are included in
          subscriber acquisition costs.  Subscriber acquisition costs are
          deferred and amortized over a period determined by calculating
          the ratio of current revenue related to the direct response
          advertising versus the total expected revenue, or twelve months,
          whichever is shorter.  These costs relate directly to subscriber
          solicitations and principally include the printing, production
          and shipping of starter packages and the costs of obtaining
          qualified prospects by various targeted direct marketing
          programs.  No indirect costs are included in subscriber
          acquisition costs.  To date, all subscriber acquisition costs
          have been incurred for the solicitation of specifically
          identified prospects.  It is possible that these estimates of
          anticipated gross revenue could be reduced in the future based on
          management's periodic evaluation of the estimates used.  As a
          result, the carrying value and/or the amortization period and
          carrying value of the subscriber acquisition costs could be
          reduced.

           Deferred subscriber acquisition costs capitalized during fiscal
          years 1996 and 1997 were $14,368,000 and $6,542,000,
          respectively.  Amortization and write-offs for fiscal years 1995,
          1996 and 1997 were $2,755,000, $12,225,000 and $8,914,000,
          respectively, and have been included in sales and marketing
          expense in the Company's consolidated statement of operations.  

           The amounts charged to advertising expense were $4,534,000 in
          1995, $7,526,000 in 1996 and $4,680,000 in 1997.

           Concentrations of Credit Risk

           Financial instruments that potentially subject the Company to
          concentrations of credit risk consist principally of cash
          investments and trade receivables. The Company's cash investment
          policies limit investments to short-term, low-risk instruments.
          Concentrations of credit risk with respect to trade receivables
          are limited due to the large number of customers comprising the
          Company's customer base. During 1995, 1996, and 1997, the Company
          incurred bad debt expense in the amount of $182,000, $1,851,000
          and $1,511,000, respectively.

           Translation Adjustments

           The functional currency for all foreign operations is the local
          currency.  As such, all assets and liabilities denominated in
          foreign currencies are translated at the exchange rate on the
          balance sheet date.  Revenue, costs, and expenses are translated
          at weighted average rates of exchange prevailing during the
          period.  Translation adjustments are carried as a separate
          component of stockholders' equity.  Gains and losses resulting
          from foreign currency transactions are included in income.

           Basic and Diluted Net Loss Per Share

           In February 1997, the Financial Accounting Standards Board
          issued Statement No. 128, ("SFAS 128") "Earnings Per Share." 
          Under SFAS 128, basic loss per share is computed on the basis of
          weighted average common shares outstanding.  Diluted loss per
          share considers potential common stock instruments in the
          calculation.  The Company adopted SFAS 128 for its fiscal year
          ending December 31, 1997, including the requirement for


                                     F-8
     


          retroactive application.  The adoption of SFAS 128 had no effect
          on the Company's previously reported loss per share.  Potential
          common stock instruments, which include options, are not included
          in the loss per share calculation as their effect is anti-
          dilutive.

           Income Taxes

           Income taxes are accounted for under Statement of Financial
          Accounting Standards No. 109, "Accounting for Income Taxes."
          Under this method, deferred tax assets and liabilities are
          determined based on differences between the financial reporting
          and tax bases of assets and liabilities and are measured using
          the enacted tax rates and laws that will be in effect when the
          differences are expected to reverse.

          NOTE 3   INVESTMENTS

           The Company has classified all investments as available-for-
          sale.  Available-for-sale securities are carried at fair market
          value based on quoted market prices with unrealized gains and
          losses, net of tax, reported in stockholders' equity.  Realized
          gains and losses and declines in value judged to be other-than-
          temporary on available-for-sale securities are included in
          investment income.  Interest on securities classified as
          available-for-sale is included in investment income.

           The following is a summary of available-for-sale securities (in
          thousands):

           At December 31, 1996 and 1997, the estimated fair value of the
          commercial paper and money market instruments approximated cost,
          and the amount of gross unrealized gains and losses was not
          significant. At December 31, 1996, the cost of equity securities
          was $309,000 and unrealized gains totaled $540,000.  All
          commercial paper and money market instruments mature within one
          year. During 1997, the Company recorded a realized gain on equity
          securities of $1,274,000 (see note 5).

          NOTE 5   ACQUISITIONS

           In August 1995, the Company completed the acquisition of
          Professional Internet Consulting, Inc. ("PICnet") pursuant to an
          Agreement and Plan of Reorganization in a transaction accounted
          for using the purchase method of accounting.  As consideration
          for all of the outstanding shares of PICnet, the Company issued
          32,207 shares of its common stock at an approximate fair market
          value of $31.05 per share with a total value of approximately
          $1,000,000. Additionally, the Company acquired net liabilities
          with a fair value of approximately $373,000.  The resulting
          consideration in excess of assets acquired totaling $1,373,000
          represents the goodwill acquired.  The goodwill was amortized
          over a period of eighteen months and is fully amortized at
          December 31, 1997.  The results of PICnet have been included in
          the consolidated financial statements beginning in August 1995.

           In June 1995, the Company acquired common stock in The McKinley
          Group, Inc. ("McKinley") in exchange for $1,200,000 cash and
          $300,000 of common stock.  In 1996 Excite, Inc. ("Excite")
          acquired all of the outstanding shares of McKinley and the
          Company received shares of Excite in exchange for its investment
          in McKinley.  The Company recorded a loss of $1,200,000 in 1996
          to reflect the estimated value of the shares received.  During
          1997, the Company sold the Excite shares for a net gain of
          $1,274,000.

          NOTE 6   INDUSTRY SEGMENT REPORTING

           The Company operates in one principal industry segment, as a
          provider of Internet solutions, and markets its services
          internationally through foreign subsidiaries.  The Company's
          services are provided primarily to the individual and small
          business markets.

           Intersegment sales and transfers are not material.  Revenue is
          based on the location of the entity providing service. Loss from
          operations represents total revenue less costs and expenses, and
          does not include other income or provision for income taxes. 
          Identifiable assets of geographic areas are those assets used in
          the Company's operations in each area.  In September 1996, the
          Company signed a letter of intent for a joint venture agreement
          with a Brazilian conglomerate.  No significant operating costs
          were incurred during 1996 relating to the joint venture.  During
          1997, the Company recorded $2,013,000 as its share of operating
          losses relating to the joint venture, which have been included in
          sales and marketing expense in the Company's consolidated
          statement of operations. During December 1997, the Company
          transferred its interest in the Brazilian joint venture to its
          partner, Grupo Itamarati.

           Legal Proceedings

           The Company is subject to legal proceedings and claims which
          have arisen in the ordinary course of its business and have not
          been finally adjudicated. In the opinion of management,
          settlement of these actions when ultimately concluded will not
          have a material adverse effect on trends in results of operations
          or the financial condition of the Company.  This conclusion is
          based upon current facts and circumstances, however, and it is
          possible that a change in the facts and circumstances relating to
          such legal proceedings and claims could result in a development
          that would have a material adverse effect on the results of
          operations or financial condition of the Company.

          NOTE 8   EMPLOYEE BENEFIT PLANS

           The Company has elected to follow Accounting Principles Board
          Opinion No. 25, "Accounting for Stock Issued to Employees," (APB
          25) and related Interpretations in accounting for its employee
          stock awards because, as discussed below, the alternative fair
          value accounting provided for under SFAS No. 123, "Accounting for
          Stock-Based Compensation," requires use of option valuation
          models that were not developed for use in valuing employee stock

          options.  Under APB 25, when the exercise price of the Company's
          employee stock options equals the market price of the underlying
          stock on the date of grant, no compensation expense is
          recognized. 

           1993 Stock Option Plan

           In 1993, the Company approved and adopted its 1993 Stock Option
          Plan (the "Plan"). The Plan is administered by the Stock Option
          Committee of the Board of Directors. The Plan provides for the
          granting of options to purchase common stock to eligible
          employees, directors and consultants of the Company. A total of
          3,153,571 shares of common stock may be issued pursuant to
          options granted under the Plan. The options generally vest over
          three to five year periods and are exercisable for up to ten
          years following the date of grant.

               During 1996 and 1997, certain outstanding options were
          exchanged at the election of the option holder.  In September
          1996, 67,408 shares were exchanged and repriced for 39,995 shares
          and in January 1997, 457,846 shares were exchanged and repriced
          for 272,084 shares.  On the effective date of the trade in,
          eligible options were issued at a price lower than the traded in
          option and at a price higher than the market value.  The trade in
          ratio was set such that the number of old options times their
          option price approximates the new number of options times their
          exercise price.  This program was offered to all employees
          excluding members of the Board of Directors and Officers of the
          Company.  However, option holders participating in the first
          exchange were not eligible for the second program.

               During May 1997, 1,182,374 outstanding options were
          exchanged at the election of certain stock option holders and
          repriced for 632,546 options. This was offered to all employees
          including members of the Board of Directors and officers of the
          Company.

               Employee Stock Purchase Plan

               In 1994, the Board of Directors of the Company approved and
          adopted an Employee Stock Purchase Plan (the "ESPP") to provide
          employees of the Company with an opportunity to purchase common
          stock through payroll deductions. Under the ESPP, 200,000 shares
          of common stock were reserved for issuance, subject to anti-
          dilution adjustments. The ESPP was effective upon the
          effectiveness of the Company's initial public offering in
          December 1994.  Each offering period under the ESPP was six
          months long, although the Board of Directors had the authority to
          determine the duration of offering periods, up to a maximum of 27
          months. Eligible employees could participate in the ESPP by
          authorizing payroll deductions of an amount determined by the
          Board of Directors.  The amount of authorized payroll deductions
          could not be less than 1% nor more than 10% of an employee's
          initial cash compensation, not to exceed $25,000 per year.
          Amounts withheld were applied at the end of every six-month
          accumulation period to purchase shares of common stock, but not
          more than 2,500 shares, or such other number of shares as the
          Board of Directors determined.

               Participants could withdraw their contributions at any time
          before stock was purchased, and such contributions were returned
          to the participants without interest. The purchase price was
          equal to 85% of the lower of (i) the market price of common stock
          immediately before the beginning of the applicable period or (ii)
          the market price of common stock at the time of the purchase. As
          of December 31, 1996 and 1997, 75,400 and 138,000 shares of
          common stock were purchased under the ESPP, respectively.

               The Company's ESPP was dissolved in conjunction with
          NETCOM's merger with ICG Communications, Inc. (see note 11).

               Pro Forma Information

               In October 1995, the Financial Accounting Standards Board
          ("FASB") issued SFAS No. 123, "Accounting for Stock-Based
          Compensation."  The Company adopted SFAS No. 123 in 1996. As
          allowed by SFAS No. 123, the Company applies APB 25 for purposes
          of determining net loss and provides the pro forma disclosure
          requirements of SFAS No. 123.  Pro forma information regarding
          net loss per share as required by SFAS No. 123, also requires
          that the information be determined as if the Company has
          accounted for its employee stock options (including shares issued
          under the stock purchase plan) granted subsequent to December 31,
          1994 under the fair value method.  The fair value for these
          options was estimated at the date of grant using a Black-Scholes
          option pricing model with the following weighted average
          assumptions for 1995, 1996 and 1997: risk-free interest rate of
          6%, a zero percent dividend yield, volatility factor of the
          expected market price of the Company's common stock of 80% for
          all three years; and a weighted average expected life of the
          option of 1.6 years from vest date. 

               The Black-Scholes option valuation model was developed for
          use in estimating the fair value of traded options which have no
          vesting restrictions and are fully transferable. In addition,
          option valuation models require the input of highly subjective
          assumptions including the expected stock price volatility.
          Because the Company's employee stock options have characteristics
          significantly different from those of traded options, and because
          changes in the subjective input assumptions can materially affect
          the fair value estimate, in management's opinion, the existing
          models do not necessarily provide a reliable single measure of
          the fair value of its employee stock options.

               The weighted average estimated fair value of stock options
          granted during 1995, 1996 and 1997 was $18.44, $16.73 and $11.94
          per share, respectively.  The weighted average estimated fair
          value of shares granted under the Employee Stock Purchase Plan
          during 1995, 1996 and 1997 was $7.18, $5.75 and $4.86,
          respectively.

               For purposes of pro forma disclosures, the estimated fair
          value of the options is amortized to expense over the options'
          vesting period. The Company's pro forma information follows (in
          thousands except for earnings per share information):

          Employee Savings Plan

               The Company has a savings plan (the "Savings Plan") that
          qualifies as a deferred salary arrangement under Section 401(k)
          of the Internal Revenue Code.  Under the Savings Plan,
          participating employees may defer a portion of their pretax
          earnings, up to the Internal Revenue Service annual contribution
          limit.  Prior to 1997, the Company matched 50% of each employee's
          contributions up to a maximum of 6% of the employee's eligible
          earnings. During 1997, the Company began matching 100% of each
          employee's contributions up to a maximum of 3% of the employee's
          eligible earnings.  Company matches vest over four years.

          NOTE 9    INCOME TAXES

               The provision for income taxes for 1995, 1996 and 1997 in
          the amount of $15,000, $23,000 and $38,000, respectively,
          consists entirely of  international and state minimum taxes since
          the Company incurred pre-tax losses in each year.

          and liabilities for federal and state income taxes are as follows

               Realization of deferred tax assets is dependent on future
          earnings, the timing and amount of which are uncertain. 
          Accordingly, a valuation allowance, in an amount equal to the net
          deferred tax assets as of December 31, 1996 and 1997 has been
          established to reflect these uncertainties.  The change in the
          valuation allowance was a net increase of $24,446,000 and
          $13,494,000 in 1996 and 1997, respectively.  Approximately
          $124,000 of the valuation allowance at December 31, 1997 is
          attributable to the tax benefits of disqualifying dispositions of
          stock received through incentive stock options and the Company's
          employee stock purchase plan, the benefit of which will be
          credited to additional paid-in capital when realized.

               At December 31, 1997, the Company had federal, state and
          foreign net operating loss carryforwards of approximately
          $89,000,000, $37,000,000 and $27,000,000, respectively, which
          will expire in the years 1999 through 2011.  Under the Tax Reform
          Act of 1986, the amounts and benefits of net operating losses
          that can be carried forward may be impaired in certain
          circumstances, including a cumulative change of more than 50%
          over a three year period. The Agreement and Plan of Merger, as
          amended, with ICG Communications, Inc. which was consummated on
          January 21, 1998 (see note 11) resulted in a change in ownership
          greater than 50%. Accordingly, the Company's net operating loss
          carryforwards incurred prior to January 21, 1998 that can be
          utilized to reduce future taxable income are limited to
          approximately $15 million per year. 

          NOTE 10   RESTRUCTURING AND RELATED CHARGES

               Restructuring and related charges of $1,879,000 during 1997
          are the result of a decision by management to restructure
          operations of the Company's subsidiary in the United Kingdom. 
          The charge includes $1,356,000 in accrued expenses for costs to
          terminate excess leased office facilities and a write-off of
          office equipment, furniture and building improvements as a result
          of consolidating office space, a $356,000 write-down of
          previously capitalized deferred subscriber acquisition costs and
          $167,000 for severance costs relating to approximately twelve
          employees.

               Agreement and Plan of Merger with ICG Communications, Inc.

               On October 12, 1997, the Company entered into an Agreement
          and Plan of Merger, as amended (the "Merger Agreement"), with ICG
          Communications, Inc., a Delaware corporation ("ICG"), pursuant to
          which ICG agreed to acquire the Company through a tax-free merger
          (the "Merger") of a newly formed Delaware subsidiary of ICG with
          and into the Company.  On January 21, 1998, all contingencies of
          the merger were satisfied and the Merger was consummated.  Under
          the terms of the Merger Agreement, each share of the Company's
          common stock has been exchanged for 0.8628 shares of common stock
          of ICG ("ICG Common Stock").  The Company became a wholly owned
          subsidiary of ICG Services, Inc., a Delaware corporation, which
          is a wholly owned subsidiary of ICG Communications, Inc., and
          ceased to exist as an independent entity.

               On December 31, 1997, there were $1,500,000 of deferred
          merger expenses included in prepaid expenses which were
          subsequently expensed in January 1998.

                        INFORMATION NOT REQUIRED IN PROSPECTUS

          ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS

             ICG Services' Certificate of Incorporation provides that the
          Company will indemnify, to the fullest extent permitted by the
          General Corporation Law of the State of Delaware, as amended from
          time to time (the "GCL"), all persons, whom it may identify
          pursuant thereto.  ICG Services' By-laws contain a similar
          provision requiring indemnification of its directors and officers
          to the fullest extent authorized by the GCL. The GCL permits a
          corporation to indemnify its directors and officers (among
          others) against expenses (including attorneys' fees), judgments,
          fines and amounts paid in settlement actually and reasonably
          incurred by them in connection with any action, suit or
          proceeding brought (or threatened to be brought) by third
          parties, if such directors or officers acted in good faith and in
          a manner they reasonably believe 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
          their conduct was unlawful. In a derivative action, i.e., one by
          or in the right of the corporation, indemnification may be made
          for expenses (including attorneys' fees) actually and reasonably
          incurred by directors and officers in connection with the defense
          or settlement of such action if they had acted in good faith and
          in a manner they reasonably believed to be in or not opposed to
          the best interests of the corporation, except that no
          indemnification shall be made in respect of any claim, issue or
          matter as to which such person shall have been adjudged 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 of
          such expenses. The GCL further provides that, to the extent any
          director or officer has been successful on the merits or
          otherwise in defense of any action, suit or proceeding referred
          to in this paragraph, or in defense of any claim, issue or matter
          therein, such person shall be indemnified against expenses
          (including attorneys' fees) actually and reasonably incurred by
          him in connection therewith. In addition, ICG Services'
          Certificate of Incorporation contains a provision limiting the
          personal liability of its directors for monetary damages for
          certain breaches of their fiduciary duty. ICG Services and ICG
          Equipment are additional insureds under ICG Communications'
          indemnification insurance under which directors and officers are
          insured against certain liability that may incur in their
          capacity as such.

             See Item 22 of this Registration Statement regarding the
          position of the Securities and Exchange Commission on
          indemnification for liabilities arising under the Securities Act.

          ITEM 22. UNDERTAKINGS.

             Insofar as indemnification for liabilities arising under the
          Securities Act of 1933 may be permitted to directors, officers
          and controlling persons of the 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 Act
          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 the successful
          defense of any action, suit or proceeding) is asserted by such
          director, officer or controlling person in connection with the
          securities being registered, the 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 Act and will be governed by the final
          adjudication of such issue.

             The undersigned Registrant hereby undertakes:

             (1)  To respond to requests for information that is
                  incorporated by reference into the prospectus pursuant to
                  Items 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;

             (2)  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;

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


                                      II-4
     

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

               (ii) To reflect in the prospectus any facts or events
                    arising after the effective date of the registration
                    statement (or the most recent post-effective amendment
                    thereof) which, individually or in the aggregate,
                    represent a fundamental change in the information set
                    forth in the registration statement;

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

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

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