          (1)  Estimated solely for the purpose of calculating the amount
               of the registration fee based on the average of the bid and
               asked prices of the Preferred Securities as reported on the
               PORTAL Market on November 14, 1997, in accordance with Rule
               457(c) under the Securities Act.
          (2)  The Preferred Securities are exchangeable for the common
               stock, par value $.01 per share (the "Common Stock"), of ICG
               Communications, Inc. in whole or in part at the holder's
               option. The number of shares of Common Stock to be
               registered represents the number of shares of Common Stock
               that may be issued upon exchange of the Preferred
               Securities. Each Preferred Security is initially
               exchangeable into 2.0811 shares of Common Stock, subject to
               adjustment under certain circumstances. Pursuant to Rule
               416, this Registration Statement also registers such
               indeterminate number of additional shares of Common Stock as
               may be required as a result of an adjustment in the number
               of shares of Common Stock issuable upon exchange by reason
               of the formula contained in the terms of the Preferred
               Securities. Shares of Common Stock issued upon exchange of
               the Preferred Securities will be issued without the payment
               of additional consideration.
          (3)  Estimated solely for the purpose of calculating the amount
               of the registration fee based on the average of the bid and
               asked prices of the Common Stock as reported on the Nasdaq
               National Market on November 17, 1997, in accordance with
               Rule 457(c) under the Securities Act. Represents shares of
               Common Stock to be sold by the Selling Stockholder named
               herein.
          (4)  Pursuant to Rule 457(n) under the Securities Act, no
               separate fee is payable for the Guarantee.

          SPECIFICALLY STATES THAT THIS REGISTRATION STATEMENT SHALL

                           _______________________________


               This Prospectus relates to the resale by the holders thereof
          of the 6 3/4% Exchangeable Limited Liability Company Preferred
          Securities (the "Preferred Securities"), liquidation amount $50
          per Preferred Security, which represent preferred undivided
          beneficial interests in the assets of ICG Funding, LLC, a limited
          liability company formed under the laws of the State of Delaware
          ("Funding"), and the shares of common stock, par value $.01 per
          share (the "Common Stock"), of ICG Communications, Inc., a
          Delaware corporation ("ICG" and, together with its subsidiaries,
          "ICG" or the "Company"), issuable upon exchange of the Preferred
          Securities. This Prospectus also relates to the resale by Funding
          of up to 200,000 shares of Common Stock. The Preferred
          Securities were issued and sold (the "Original Offering") on
          September 24, 1997 (the "Original Closing Date") and October 3,
          1997 to the Initial Purchasers (as defined herein) and were
          simultaneously resold by the Initial Purchasers in transactions
          exempt from the Securities Act of 1933, as amended (the
          "Securities Act"), in the United States to persons reasonably
          believed by the Initial Purchasers to be qualified institutional
          buyers as defined in Rule 144A under the Securities Act. The
          Preferred Securities are traded in the Private Offering, Resales
          and Trading through Automated Linkages ("PORTAL") Market. All of
          the beneficial interests in the assets of Funding represented by
          common securities of Funding (the "Common Securities" and,
          together with the Preferred Securities, the "Funding Securities")
          are owned directly by ICG. Funding exists for the exclusive
          purposes of issuing the Funding Securities and investing the
          proceeds of the sale thereof in the preferred stock of ICG
          mandatorily redeemable 2009, par value $.01 per share (the "ICG
          Preferred Stock"), and certain U.S. government securities. The
          ICG Preferred Stock ranks on a parity with all outstanding
          preferred stock of ICG, senior to the common stock of ICG and
          subordinate to all indebtedness and other liabilities of ICG. In
          the event of a liquidation, dissolution, winding-up or
          termination of Funding, the then holders of the Preferred
          Securities will have a preference over the holders of the Common
          Securities with respect to payments in respect of distributions
          and payments upon liquidation, redemption and otherwise.  See
          "Description of the Preferred Securities - Ranking."

                SEE "RISK FACTORS" BEGINNING ON PAGE 12 FOR INFORMATION
                 THAT SHOULD BE CONSIDERED BY PROSPECTIVE INVESTORS.

              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.

                  The date of this Prospectus is XXXXXXXXX XX, 1997

     <PAGE>

               Each Preferred Security is exchangeable in the manner
          described herein at the option of the holder, at any time prior
          to the Mandatory Redemption Date (as defined herein), into shares
          of Common Stock, at an initial exchange rate of 2.0811 shares of
          Common Stock per $50 liquidation preference per Preferred
          Security (equivalent to an exchange price of $24.025 per share of
          Common Stock), subject to adjustment in certain circumstances.
          See "Description of the Preferred Securities - Exchange Rights -
           Exchange Rate Adjustments." The Common Stock is quoted on the
          Nasdaq National Market under the symbol "ICGX." On November 17,
          1997, the last reported sale price of Common Stock was $21.50 per
          share.

               The Preferred Securities and the Common Stock issuable upon
          exchange of the Preferred Securities (the "Offered Securities")
          may be offered and sold from time to time by the holders named
          herein or by their transferees, pledgees, donees or their
          successors (collectively, the "Selling Holders") pursuant to this
          Prospectus. The Offered Securities may be sold by the Selling
          Holders from time to time directly to purchasers or through
          agents, underwriters or dealers. See "Plan of Distribution" and
          "Selling Holders." If required, the names of any such agents or
          underwriters involved in the sale of the Offered Securities and
          the applicable agent's commission, dealer's purchaser price or
          underwriter's discount, if any, will be set forth in an
          accompanying supplement to this Prospectus (the "Prospectus
          Supplement"). The Selling Holders will receive all of the net
          proceeds from the sale of the Offered Securities and will pay all
          underwriting discounts and selling commissions, if any,
          applicable to any such sale. No portion of the net proceeds of
          this offering will be received by ICG or Funding. ICG is
          responsible for payment of all other expenses incident to the
          offer and sale of the Offered Securities. The Selling Holders and
          any broker-dealers, agents or underwriters which participate in
          the distribution of the Offered Securities may be deemed to be
          "underwriters" within the meaning of the Securities Act, and any
          commission received by them and any profit on the resale of the
          Offered Securities purchased by them may be deemed to be
          underwriting commissions or discounts under the Securities Act.
          See "Plan of Distribution" for a description of indemnification
          arrangements. 

               Holders of Preferred Securities are entitled to receive
          dividends on the Preferred Securities at the rate of 6 3/4% per
          annum of the liquidation preference of Preferred Securities,
          payable quarterly. All dividends will be cumulative, whether or
          not earned or declared, on a daily basis from the Original
          Closing Date and will be payable quarterly in arrears on
          February 15, May 15, August 15 and November 15 of each year
          (each, a "Dividend Payment Date"), commencing on November 15,
          1997 (to holders of record at the close of business on
          February 1, May 1, August 1 and November 1 immediately preceding
          the Dividend Payment Date). Through and including November 15,
          2000, dividends on the Preferred Securities will be paid in cash.
          Thereafter, dividends on the Preferred Securities may be paid at
          Funding's option, in (i) cash, (ii) Common Stock, based upon 90%
          of the Average Market Value of the Common Stock or (iii) any
          combination of cash or Common Stock; provided that any dividend
          payment must be made in cash to the extent ICG shall have
          provided Funding with cash (whether through dividends on the ICG
          Preferred Stock or otherwise) to make all or any portion of such
          dividend payment with respect to the Preferred Securities. The
          Indentures (as defined herein) effectively prohibit ICG from
          providing cash to Funding (except as a result of Funding selling
          Common Stock). If any dividend (or portion thereof) payable in
          cash on any Dividend Payment Date is not declared or paid in full
          in cash on such Dividend Payment Date, the amount of such
          dividend that is payable and that is not paid in cash on such
          date will cumulate at the dividend rate, compounding quarterly,
          until declared and paid in full. See "Description of the
          Preferred Securities - The Guarantee; Lack of Practical Benefit
          to Holders from the Guarantee."

               Dividends on the Preferred Securities will be paid to the
          extent that Funding has funds legally available for the payment
          of such dividends. Amounts available to Funding for dividends to
          the holders of the Preferred Securities will be limited to shares
          of Common Stock received by Funding from ICG as dividends on the
          ICG Preferred Stock (and proceeds from any sales of such Common
          Stock by Funding) and the interest on and principal of the U.S.
          Treasury strips ("Treasury Strips") that are held in the Escrow
          Account (as defined herein). See "Description of the Preferred
          Securities -- Escrow." The ICG Preferred Stock provides that ICG
          shall pay dividends to Funding, payable in Common Stock, in an
          amount sufficient to allow Funding to pay dividends on the
          Preferred Securities in full. Any such Common Stock received by
          Funding may be paid as a dividend to the holders of the Preferred
          Securities or sold in the open market and the cash proceeds of
          sale would be used to pay cash dividends on the Preferred
          Securities. The payment of dividends out of moneys held by
          Funding, and payments on liquidation of Funding or the redemption

                                      2
     <PAGE>

          of Preferred Securities, as set forth below, are guaranteed by
          ICG (the "Guarantee") to the extent described herein and under
          "Description of the Preferred Securities - The Guarantee; Lack of
          Practical Benefit to Holders from the Guarantee." The Guarantee
          covers payments of dividends and other payments on the Preferred
          Securities only if and to the extent Funding has funds available
          therefor, which will not be the case unless ICG has made a
          dividend payment or other payments on the ICG Preferred Stock
          held by Funding as its sole asset. ICG's obligations under
          Guarantee, taken together with its obligations under the ICG
          Preferred Stock and the Written Action (as defined herein) and
          Certificate of Designation relating to the ICG Preferred Stock
          (as defined herein), including its liabilities to pay costs,
          expenses, debts and obligations of Funding (other than with
          respect to the Funding Securities), constitute a full and
          unconditional guarantee by ICG of amounts due on the Preferred
          Securities. See "Description of the Preferred Securities - The
          Guarantee; Lack of Practical Benefit to Holders from the
          Guarantee."

               The obligations of ICG under the Guarantee are subordinate
          and junior in right of payment to all other liabilities of ICG.
          If ICG does not make dividend payments on the ICG Preferred
          Stock, Funding will not have sufficient funds to redeem or make
          distributions on the Preferred Securities, in which event holders
          of the Preferred Securities would not be able to rely on the
          Guarantee for payment of such amounts until Funding has
          sufficient funds available therefor. The obligations of ICG under
          the ICG Preferred Stock are subordinate and junior in right of
          payment to all present and future Senior Indebtedness (as defined
          herein) of ICG.

               Unless earlier redeemed or exchanged, the Preferred
          Securities must be redeemed on November 15, 2009, out of funds
          legally available therefor, by Funding at redemption prices set
          forth herein. See "Description of the Preferred Securities -
          Provisional Redemption by Funding."

               The Preferred Securities will also be subject to optional
          redemption by Funding on or after November 18, 2000 (the "Initial
          Redemption Date"). At any time and from time to time on or after
          the Initial Redemption Date and until the Mandatory Redemption
          Date, Funding will have the right to redeem, in whole or in part,
          the Preferred Securities at the redemption prices set forth
          herein. See "Description of the Preferred Securities - Optional
          Redemption by Funding."

               The ICG Preferred Stock is exchangeable into Common Stock at
          the option of Funding (upon request by a holder of the Preferred
          Securities) at any time prior to the business day immediately
          preceding the date of repayment of such ICG Preferred Stock at an
          exchange rate based on the exchange rate of the Preferred
          Securities. See "Description of the Preferred Securities -
          Exchange Rights."

               In the event of any voluntary or involuntary liquidation,
          dissolution, winding-up or termination of Funding (each a
          "Liquidation"), the then holders of the Preferred Securities will
          be entitled to receive out of the assets of Funding (which will
          include the ICG Preferred Stock, any interest on and principal of
          the Treasury Strips that are held in the Escrow Account, any
          Common Stock that Funding received from ICG as a dividend (or
          otherwise) and has not distributed as a dividend on the Preferred
          Securities or sold in the open market, and any other assets of
          Funding), after satisfaction of liabilities to creditors, if any,
          distributions in an amount equal to the aggregate of the stated
          liquidation preference of $50 of Preferred Security plus accrued
          and unpaid dividends thereon to the date of payment (the
          "Liquidation Distribution"). See "Description of the Preferred
          Securities - Liquidation Distribution Upon Dissolution."

               If, upon any such Liquidation, the Liquidation Distribution
          can be paid only in part because Funding has insufficient assets
          available to pay in full the aggregate Liquidation Distribution,
          then the amounts payable by Funding on the Preferred Securities
          shall be paid on a pro rata basis. ICG will be obligated to pay
          dividends, consisting of ICG Preferred Stock, to Funding so that
          it will be able to make the Liquidation Distribution in full.

                                AVAILABLE INFORMATION

               ICG is subject to the informational requirements of the
          Securities Exchange Act of 1934, as amended (the "Exchange Act"),
          and in accordance with the Exchange Act files periodic reports,
          proxy statements and other information with the Securities and
          Exchange Commission (the "Commission"). Such reports, proxy
          statements and other information filed by the Company with the
          Commission can be inspected and copied (at prescribed rates) at
          the Commission's Public Reference Section, Room 1024, Judiciary
          Plaza, 450 Fifth Street, N.W., Washington, D.C. 20549, and at the
          Regional Offices of the Commission located at Citicorp Center,
          500 West Madison Street, Suite 1400, Chicago, Illinois 60661-2511
          and 7 World Trade Center, 13th Floor, New York, New York 10048.
          Such material may also be accessed electronically by means of the
          Commission's home page on the Internet at http://www.sec.gov.

               ICG and Funding have filed with the Commission a
          registration statement on Form S-3 (the "Registration Statement")
          under the Securities Act of 1933, as amended (the "Securities
          Act"), with respect to the securities offered hereby. This
          Prospectus, which is part of the Registration Statement, does not
          contain all the information set forth in the Registration
          Statement and the exhibits and schedules thereto, certain items
          of which are omitted in accordance with the rules and regulations
          of the Commission. For further information with respect to the
          Company and the securities offered hereby, reference is hereby
          made to the Registration Statement and such exhibits and
          schedules. The Registration Statement, including the exhibits and
          schedules thereto, may be inspected at, and copies thereof may be
          obtained at prescribed rates from, the public reference
          facilities of the Commission set forth above. 

               No separate financial statements of Funding are included
          herein. ICG and Funding do not consider that such financial
          statements would be material to holders of the Offered Securities
          because Funding is a newly created special purpose entity, has no
          operating history and no independent operations and is not
          engaged in, and does not propose to engage in, any activity other
          than as set forth below. See "Summary - Funding."

               The terms "fiscal" and "fiscal year" refer to ICG's fiscal
          year ending September 30; and all dollar amounts are in U.S.
          dollars. Effective January 1, 1997, ICG changed its fiscal year
          end to December 31 from September 30. Industry figures were
          obtained from reports published by the Federal Communications
          Commission (the "FCC"), the U.S. Department of Commerce,
          Connecticut Research (an industry research organization) and
          other industry sources, which the Company has not independently
          verified.

                                  PROSPECTUS SUMMARY

               The following summary is qualified in its entirety by the
          more detailed information and consolidated financial statements,
          and notes thereto, appearing in the documents incorporated by
          reference herein. Unless the context otherwise requires, the term
          "Company" means the combined business operations of ICG and its
          subsidiaries, including ICG Holdings (Canada), Inc. ("Holdings-
          Canada") and ICG Holdings, Inc. ("Holdings"). Certain statements
          contained in this Prospectus with respect to the Company's plans
          and strategy for its business and related financing are forward-
          looking statements (as such term is defined in the Private
          Securities Litigation Reform Act). Such statements are subject to
          risks and uncertainties and, as a result, actual results may
          differ materially from those expressed in or implied by such
          forward-looking statements. For a discussion of important risks
          of an investment in the Offered Securities, including factors
          that could cause actual results to differ materially from results
          referred to in the forward-looking statements, see "Risk
          Factors." Investors should carefully consider the information set
          forth under the caption "Risk Factors," including the risks
          relating to historical and anticipated operating losses and
          negative cash flows. 


                                     THE COMPANY

               The Company is one of the largest independent providers of
          competitive local telephone services in the United States, based
          on estimates of the industry's 1996 revenue. Competitive local
          exchange carriers ("CLECs") seek to provide an alternative to the
          incumbent local exchange carriers ("ILECs") for a full range of
          telecommunications services in the increasingly deregulated
          telecommunications industry. As a CLEC, the Company operates
          networks in four regional clusters covering major metropolitan
          statistical areas in California, Colorado, Ohio and the
          Southeast. The Company also provides a wide range of network
          systems integration services and maritime and international
          satellite transmission services. As a leading participant in the
          rapidly growing competitive local telecommunications industry,
          the Company has experienced significant growth, with total
          revenue increasing from $59.1 million for fiscal 1994 to $252.5
          million for the 12-month period ended September 30, 1997. 

               The Federal Telecommunications Act of 1996 (the
          "Telecommunications Act") and procompetitive state regulatory
          initiatives have substantially changed the telecommunications
          regulatory environment in the United States. Due to these
          regulatory changes, the Company is now permitted to offer all
          interstate and intrastate telephone services, including
          competitive local dial tone. The Company is marketing and selling
          local dial tone services in major metropolitan areas in the
          following regions: California, which began service in late
          January 1997, followed by Ohio in February 1997, Colorado in
          March 1997 and the Southeast in May 1997. During the nine months
          ended September 30, 1997, the Company sold approximately 92,000
          local access lines, of which approximately 51,000 were in service
          at that date. As a complement to its local exchange services, the
          Company has begun marketing bundled service offerings which
          include long distance, enhanced telecommunications services and
          data services. The Company has 18 operating high capacity digital
          voice switches and 15 data communications switches, and plans to
          install additional switches as demand warrants. To facilitate the
          expansion of its services, the Company has entered into
          agreements with Lucent Technologies, Inc. ("Lucent"), Northern
          Telecom Inc. ("Nortel") and Cascade Communications, Inc.
          ("Cascade") to purchase a full range of switching systems, fiber
          optic cable, network electronics, software and services.  The
          Company has signed an Agreement and Plan of Merger (the "Merger
          Agreement") with NETCOM On-Line Communication Services, Inc.
          ("NETCOM"), an Internet service provider, in order to broaden the
          Company's product and service offerings. See " --Recent
          Developments." 

               In developing its telecommunications service offerings, the
          Company continues to invest significant resources to expand its
          network. This expansion is being undertaken through a combination
          of constructing owned facilities, entering into long-term
          agreements with other telecommunications carriers, establishing
          strategic alliances with utility companies and potentially
          through acquisitions.


          TELECOM SERVICES

               The Company operates local exchange networks in the
          following markets within its four regional clusters: California
          (Sacramento, San Diego and portions of the Los Angeles and San
          Francisco metropolitan areas); Colorado (Denver, Colorado Springs
          and Boulder); Ohio (Akron, Cleveland, Columbus and Dayton) and
          the Southeast (Birmingham, Charlotte, Louisville and Nashville).
          The Company plans to build a network in Atlanta in conjunction
          with The Southern Company ("Southern"). Through its strategic
          alliance with Central and South West Corporation ("CSW"), service

                                      7
     <PAGE>

          is expected to be offered in Austin, Corpus Christi, Dallas,
          Houston and San Antonio, Texas. See "--Recent Developments." The
          Company will continue to expand its network through construction,
          leased facilities, strategic joint ventures and potentially
          through acquisitions. The Company's operating networks have grown
          from 780 fiber route miles at the end of fiscal 1994 to 3,021
          fiber route miles as of September 30, 1997. Telecom Services
          revenue has increased from $14.9 million for fiscal 1994 to
          $158.0 million for the 12-month period ended September 30, 1997.

               Strategy

               The Company's objective is to become the dominant
          alternative to the ILEC in the markets it serves. In furtherance
          of this objective, the Company has developed strategies to
          aggressively market its broad range of telecommunications
          services to business end users and to leverage its extensive
          network footprint and its expertise in the provision of switched
          telecommunications services. The key elements of this strategy
          are: 

               Expand Service Offerings. The Company's focus is to provide
          a wide range of local, long distance and data communications
          services to business end users and wholesale customers within its
          service areas, with an emphasis on local exchange services. The
          Company believes that customers are increasingly demanding a
          broad, full service approach to providing telecommunications
          services. By offering a wide array of services bundled into
          customized packages, management believes the Company will be
          better able to capture business from telecommunications-intensive
          commercial accounts. To this end, the Company is complementing
          its core competitive local exchange services with local toll and
          long distance services tailored to the needs of its customers and
          expects to also provide tailored data services. 

               Market Services to End Users. Management believes an end
          user strategy can accelerate its penetration of the local
          services market and better leverage the Company's network
          investment. In support of this strategy, the Company has
          substantially increased its direct sales and marketing staff. The
          Company's sales force has grown from 81 and 143 people at
          September 30, 1996 and December 31, 1996, respectively, to
          approximately 400 people (including sales management, technical
          sales support and administrative support) at September 30, 1997. 

               Concentrate Markets in Regional Clusters. The Company
          believes that by focusing on regional clusters it will be able to
          more effectively service its customers' needs and efficiently
          market, operate and control its networks. As a result, the
          Company has concentrated its networks in regional clusters
          serving major metropolitan areas in California, Colorado, Ohio
          and the Southeast. The Company also intends to expand its network
          footprint to include Texas (and may also expand to Arkansas,
          Louisiana and Oklahoma) through a strategic alliance with CSW. 
          See "--Recent Developments." 

               Network Connectivity. Significant amounts of
          telecommunications traffic are carried within the Company's
          regional clusters. Management believes that integrating these
          clusters through the connection of individual networks will
          provide significant benefits, including cost advantages. These
          cost advantages would result from the Company's ability to carry
          regional traffic on-net, thereby improving operating margins by
          reducing payments to other carriers for the use of their
          facilities. Accordingly, the Company is in the process of
          connecting networks within each of its California, Colorado and
          Ohio clusters with inter-city fiber optic cable.

               Expand Alliances with Utilities. The Company has established
          and is actively pursuing strategic alliances with utility
          companies to take advantage of their existing fiber optic
          infrastructures and customer relationships. This approach affords
          the Company the opportunity to license or lease fiber optic
          facilities on a long-term basis, which is more timely and cost
          effective than constructing facilities. In addition, utilities
          possess conduit and other facilities that enable the Company to
          more easily install additional fiber to extend existing networks
          in a given market. Finally, management expects these strategic
          alliances to combine the Company's expertise in providing high
          quality telecommunications services with the utility's name
          recognition and customer relationships in marketing
          telecommunications products and services to the utility's
          customer base.


          NETWORK SERVICES

               Through the Company's wholly owned subsidiary, ICG Fiber
          Optic Technologies, Inc. ("FOTI"), the Company supplies
          information technology services and selected networking products,
          focusing on network design, installation, maintenance and support
          for a variety of end users, including Fortune 1000 firms and

                                      8
     <PAGE>

          other large businesses and telecommunications companies. Revenue
          from Network Services operations was $66.0 million for the 12-
          month period ended September 30, 1997.


          SATELLITE SERVICES

               The Company's Satellite Services operations provide
          satellite voice and data services to major cruise lines,
          commercial shipping vessels, yachts, the U.S. Navy and offshore
          oil platforms. The Company also owns a teleport facility which
          provides international voice and data transmission services.
          Revenue for Satellite Services operations was $28.5 million for
          the 12-month period ended September 30, 1997. The Company has
          been considering the disposition of its Satellite Services
          operations for some time to better focus its efforts on its core
          Telecom Services unit, although it has not approved or adopted a
          formal plan for such disposition.


          RECENT DEVELOPMENTS

               Network Expansion. The Company continues to expand its
          network footprint through several strategic initiatives with
          utility companies and other telecommunications carriers. In
          January 1997, the Company announced an agreement with a
          subsidiary of Southern that will permit the Company to construct
          a 100-mile fiber optic network in the Atlanta metropolitan area.
          In June 1997, the Company entered into an indefeasible right of
          use ("IRU") agreement with Qwest Communications Corporation for
          approximately 1,800 miles of fiber optic network and additional
          broadband capacity in California, Colorado, Ohio and the
          Southeast. The Company expects this new capacity will be used for
          the transmission of local, long distance and data communications
          services in and between the Company's markets.

               CSW Strategic Alliance. In January 1997, the Company
          announced a strategic alliance with CSW which is expected to
          develop and market telecommunications services in Austin, Corpus
          Christi, Dallas, Houston and San Antonio, Texas. The venture
          entity, a limited partnership named CSW/ICG ChoiceCom, L.P.
          ("ChoiceCom"), is based in Austin, Texas. CSW holds 100% of the
          interest in ChoiceCom and the Company has an option to purchase a
          50% interest at any time prior to July 1, 2003. Subsequent to
          July 1, 1999, if the Company has not exercised its purchase
          option, CSW will have the right to sell either 51% or 100% of the
          partnership interest in ChoiceCom to the Company. CSW and the
          Company each have two representatives on the Management Committee
          of the general partner of ChoiceCom. ChoiceCom may eventually
          offer local exchange, data communications, long haul and other
          services in other cities in Arkansas, Louisiana, Oklahoma and
          Texas.

               Cascade Agreement. In April 1997, the Company entered into
          an agreement with Cascade for the purchase of high-speed frame
          relay and asynchronous transfer mode ("ATM") switching products
          that will enable the Company to provide high-speed data
          connectivity to its customers. In addition, the Company has
          obtained turnkey services from Cascade for product planning and
          deployment of the product, including program management, network
          design, onsite operations support and training.

               Acquisition of Communications Buying Group, Inc. On
          October 17, 1997, the Company purchased approximately 91% of the
          outstanding capital stock of Communications Buying Group, Inc.
          ("CBG"), an Ohio based local exchange and Centrex reseller (the
          "CBG Acquisition"). The remaining approximately 9% will be
          purchased on or before March 24, 1998, pursuant to the terms of
          the Stock Purchase Agreement governing the CBG Acquisition. The
          Company paid total consideration of approximately $46.5 million,
          plus the assumption of certain liabilities, and expects to pay
          approximately $2.9 million for the purchase of the remaining
          approximately 9% interest. Separately, on October 17, 1997, the
          Company sold approximately $16.0 million of Common Stock to
          certain shareholders of CBG. 

               CBG currently serves customers in Cleveland, Columbus and
          Akron, Ohio as well as in surrounding areas. CBG currently has
          approximately 27,000 Centrex lines in service and over 30,000
          business lines in service, principally pursuant to various resale
          and other agreements with Ameritech Corp. ("Ameritech"), the ILEC
          in the markets it serves. CBG focuses its sales and marketing
          efforts on small to medium-sized businesses and provides a one-
          stop solution for the local and long distance needs of its
          customers.  For the calendar year 1996 and the nine months ended
          September 30, 1997, CBG's revenue was approximately $21.4 million
          and $24.1 million, respectively, and EBITDA losses were
          approximately $(1.0) million and $(1.3) million, respectively.

                                      9
     <PAGE>

               The Company believes that the business strategy of CBG is
          closely aligned with that of the Company and that it can
          successfully leverage the services offered by CBG to enhance the
          Company's offering of similar services in its existing Ohio
          markets, including all those currently served by CBG. The
          acquisition of CBG has doubled the Company's current sales
          presence in Ohio to approximately 60 people. In addition, the
          Company believes that its ability to migrate, over time, a
          portion of CBG's existing customer base to its fiber optic
          facilities offers significant cost savings. The Company believes
          that the transaction has significantly furthered its goal of
          becoming the dominant alternative to the ILEC in Ohio.

               Merger Agreement with NETCOM On-Line Communication Services,
          Inc. On October 12, 1997, the Company announced that it had
          signed the Merger Agreement with NETCOM. NETCOM is a provider of
          Internet connectivity and Web-hosting services and a suite of
          software applications. For calendar years 1995, 1996 and the nine
          months ended September 30, 1997, NETCOM reported revenue of $52.4
          million, $120.5 million and $120.1 million, respectively, and
          EBITDA of $(5.8) million, $(5.1) million and $(2.4) million,
          respectively. The Company intends to account for the business
          combination under the pooling-of-interests method of accounting.
          Subject to the approval of the shareholders of ICG and NETCOM and
          satisfaction of certain other conditions, the Company anticipates
          the merger between ICG and NETCOM (the "NETCOM Merger") to close
          during the first quarter of 1998.

               At the effective time of the NETCOM Merger (the "Effective
          Time"), each outstanding share of NETCOM common stock, $.01 par
          value, will be automatically converted into and represent the
          right to receive a number of shares of Common Stock equal to the
          Exchange Ratio. The Exchange Ratio will equal 0.8628 shares of
          Common Stock if the closing price of a share of Common Stock (the
          "Closing Price") is greater than or equal to $22.125; provided,
          however, that if the Closing Price is greater than or equal to
          $19.00 but less than $22.125, the Exchange Ratio will equal a
          fraction (rounded to the nearest ten-thousandth) determined by
          dividing $19.0625 by the Closing Price; and provided further,
          that if the Closing Price is less than $19.00, the Exchange Ratio
          will equal 1.0078. Cash will be paid in lieu of fractional
          shares.

               The Company believes that the NETCOM Merger will create a
          full-service business communications company providing a single
          source for a complete range of voice, data, Internet, Web-hosting
          and other communications services over an extensive fiber optic
          network. Currently, approximately one-half of NETCOM's customers
          are located in the Company's existing network territory. It is
          anticipated that the NETCOM Merger will enable the combined
          entity to better utilize ICG's fiber and frame relay networks.

               Financings. In March 1997, the Company raised net proceeds
          of $192.4 million from the sale of 11 5/8% Senior Discount Notes
          due 2007 (the "11 5/8% Notes") of Holdings and 14% Exchangeable
          Preferred Stock Mandatorily Redeemable 2008 (the "14% Preferred
          Stock") of Holdings. Cash interest on the 11 5/8% Notes accrues at
          11 5/8% per annum beginning March 15, 2002 and is payable quarterly,
          commencing September 15, 2002. The 14% Preferred Stock accrues
          dividends quarterly at an annual rate of 14% per annum. Dividends
          are payable quarterly in cash or, on or prior to March 15, 2002,
          at the sole option of Holdings, in additional shares of 14%
          Preferred Stock. The Company believes that its liquidity was
          improved because the 11 5/8% Notes and the 14% Preferred Stock do
          not require the payment of cash interest or cash dividends prior
          to 2002. The 11 5/8% Notes and the 14% Preferred Stock have been
          registered under the Securities Act.

               In September and October 1997, Funding, the Company's new
          wholly-owned subsidiary, completed a private placement of $132.25
          million of Preferred Securities. The Preferred Securities are
          mandatorily redeemable November 15, 2009 at the liquidation
          preference of $50.00, plus accrued and unpaid dividends.
          Dividends on the Preferred Securities will be cumulative at the
          rate of 6 3/4% per annum and will be paid in cash through
          November 15, 2000 and, thereafter, will be paid in cash and/or
          shares of Common Stock. The Preferred Securities are
          exchangeable, at the option of the holder, into Common Stock at
          an exchange price of $24.025 per share. Funding may, at its
          option, redeem the Preferred Securities any time on or after
          November 18, 2000. Prior to that time, Funding may redeem the
          Preferred Securities if the current market value of Common Stock
          equals or exceeds the exchange price, for at least 20 days of any
          consecutive 30-day trading period, by 170 percent prior to
          November 16, 1998; by 160 percent from November 16, 1998 through
          November 16, 1999; and by 150 percent from November 16, 1999
          through November 16, 2000.

                                       FUNDING

               Funding is a special purpose limited liability company
          formed under the laws of the State of Delaware pursuant to the
          filing of a Certificate of Formation with the Delaware Secretary
          of State on September 17, 1997 and the entering into of an
          Agreement of Limited Liability Company of ICG Funding, LLC, dated
          as of September 17, 1997. Funding's purpose is defined in an
          Amended and Restated Limited Liability Company Agreement of ICG
          Funding, LLC (the "Operating Agreement"), dated as of
          September 23, 1997. ICG has acquired all of the Common Securities
          of Funding in an aggregate liquidation amount equal to .01% of
          all interests in the capital, income, gain, loss, deduction and
          credit of Funding at all times. Funding exists for the exclusive
          purposes of (i) issuing the Funding Securities, representing
          undivided beneficial interests in the assets of Funding, (ii)
          investing the proceeds of the sale thereof in the ICG Preferred
          Stock and certain U.S. government securities and (iii) engaging
          in those other activities necessary or incidental thereto. The
          term of Funding will continue until December 31, 2050, unless
          dissolved before such date in accordance with the provisions of
          the Operating Agreement.

               The business and affairs of Funding are conducted by ICG, in
          its capacity as manager (the "Manager"). The duties and
          obligations of the Manager are governed by the Operating
          Agreement. Funding holds title to the ICG Preferred Stock for the
          benefit of the holders of the Funding Securities and has the
          power to exercise all rights, powers and privileges under the ICG
          Preferred Stock. ICG will pay all fees and expenses related to
          the offering of the Preferred Securities. The rights of the
          holders of the Preferred Securities, including economic rights,
          rights to information and voting rights, are as set forth in the
          Operating Agreement and the Delaware Limited Liability Company
          Act, as amended (the "LLC Act").


                                     RISK FACTORS

               SEE "RISK FACTORS," IMMEDIATELY FOLLOWING THIS SUMMARY, FOR
          A DISCUSSION OF CERTAIN RISKS THAT SHOULD BE CONSIDERED IN
          CONJUNCTION WITH AN INVESTMENT IN THE OFFERED SECURITIES,
          INCLUDING RISKS RELATED TO HISTORICAL AND ANTICIPATED OPERATING
          LOSSES, NEGATIVE CASH FLOWS AND SUBSTANTIAL INDEBTEDNESS.

                                     RISK FACTORS

               An investment in the Offered Securities 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, dependence on increased traffic on the Company's
          facilities, the successful implementation of the Company's
          strategy of offering an integrated telecommunications package of
          local, long distance, data communications and value added
          services, continued development of the Company's network
          infrastructure and actions of competitors and regulatory
          authorities, that could cause actual results to differ materially
          from the forward-looking statements.


          HISTORICAL AND ANTICIPATED FUTURE OPERATING LOSSES, NET LOSSES
          AND NEGATIVE CASH FLOWS

               The Company has incurred and expects to continue to incur
          significant operating and net losses. For the 12 months ended
          September 30, 1997, the Company had revenue of approximately
          $252.5 million, an operating loss of approximately $161.2
          million, negative EBITDA of approximately $112.6 million, cash
          used by operating activities of approximately $80.0 million,
          interest expense of approximately $106.8 million and a net loss
          of approximately $274.2 million. In conjunction with the increase
          in its service offerings, the Company will need to spend
          significant amounts on sales, marketing, customer service,
          engineering and corporate personnel prior to the generation of
          appreciable revenue. The Company expects to continue to generate
          significant negative cash flows from operating activities while
          it emphasizes development, construction and expansion of its
          Telecom Services business and until the Company establishes a
          sufficient revenue generating customer base. As the Company's
          customer base grows, the Company anticipates that operating
          margins and cash flows will improve as incremental revenue will
          exceed incremental operating expenses. This is dependent upon the
          successful implementation of the Company's local dial tone, local
          toll, data communications and long distance service strategies,
          continued development of the Company's network infrastructure,
          increased traffic on the Company's facilities, any or all of
          which may not occur, and upon actions of competitors and
          regulatory authorities. The Company had an accumulated deficit
          and stockholders' deficit of approximately $593.0 million and
          $284.5 million, respectively, at September 30, 1997. There can be
          no assurance that the Company will achieve or sustain
          profitability or positive cash flows in the future or at any time
          have sufficient resources to meet its obligations, including
          funding the mandatory redemption price of the Offered Securities
          by redeeming the ICG Preferred Stock for cash. The Company will
          be adversely affected if it does not make substantial progress
          toward achieving profitability. 


          RISKS RELATED TO LOCAL SERVICES AND SWITCHED SERVICES STRATEGIES

               The Company is a recent entrant in the competitive local
          telecommunications services industry. The local
          telecommunications services market has only recently opened to
          competition due to the passage of the Telecommunications Act,
          state and federal regulatory rulings designed to implement the
          Telecommunications Act, and negotiations with ILECs under the
          terms of the Telecommunications Act and state rulings. The
          Company is initiating the provision of long distance and data
          communications services. The Company believes that offering a
          full-service portfolio of local, long distance and data products
          is the best method for gaining market share among business
          customers and reducing customer churn. However, the Company has
          only recently begun to offer long distance services and has not
          yet generated any revenue from data services, despite its
          offering of these services since the first quarter of 1997. The
          Company is making significant operating and capital investments
          and will have to address numerous operating complexities
          associated primarily with providing local services. The Company
          will be required to develop new provisioning and technical
          support systems and will need to develop new marketing
          initiatives and hire and train a new sales force responsible for
          selling its services. The Company will also need to supplement
          the necessary billing and collection systems for local services

                                      12
     <PAGE>

          and integrate these systems with those of its long distance and
          other services, including data services. There can be no
          assurance that the Company can design and install, and coordinate
          with ILECs regarding, necessary provisioning, billing and
          customer management systems in a timely manner to permit the
          Company to provision local exchange, local toll, long distance or
          data communications services as planned.

               The Company expects to face significant competition from
          ILECs, whose core business is providing local dial tone service.
          The ILECs which currently are the dominant providers of services
          in their markets, are expected to mount a significant competitive
          response to new entrants in their market, such as the Company.
          The Company expects to face significant competitive product and
          pricing pressures from the ILECs in these markets, as well as
          from other CLECs.

               The Company began generating switched services revenue in
          the fourth quarter of fiscal 1994, and substantially all of the
          Company's current switched revenue is from wholesale customers.
          The Company is experiencing negative operating margins from the
          provision of wholesale switched services because it relies on
          ILEC networks to terminate and originate customers' switched
          traffic. The Company expects overall operating margins from
          switched services to improve as local dial tone, local toll, long
          distance and data communications services become a relatively
          larger portion of its business mix and the Company deemphasizes
          its wholesale switched services.


          CERTAIN FINANCIAL AND OPERATING RESTRICTIONS

               The terms governing certain of Holdings' senior indebtedness
          and preferred stock impose significant 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 and its subsidiaries to incur
          additional indebtedness, create liens on its assets, pay
          dividends, sell assets, engage in mergers or acquisitions or make
          investments. Failure to comply with such covenants would result
          in a default thereunder, in which case the lenders will be able
          to accelerate the maturity of the applicable indebtedness.
          Moreover, the instruments governing the Company's material
          indebtedness contain cross-default provisions which provide that
          a default under other indebtedness will be considered a default
          under the indebtedness in question. In the event that a cross-
          default were triggered, the maturity of substantially all of the
          Company's approximately $940.9 million of indebtedness at
          September 30, 1997 would be accelerated and become immediately
          due and payable. As a result, the Company would not be able to
          satisfy all of its debt obligations, which would have a
          substantial material adverse effect on the value of the Offered
          Securities and the Company's ability to continue as a going
          concern. There can be no assurance that the Company will be able
          to comply with such covenants in the future or that such
          compliance would not cause the Company to forego opportunities
          that might otherwise be beneficial to the Company.


          SUBSTANTIAL INDEBTEDNESS

               As of September 30, 1997, the Company had, on a consolidated
          basis, aggregate accreted indebtedness, including capitalized
          lease obligations, of approximately $940.9 million. With respect
          to indebtedness currently outstanding, the Company has interest
          payment obligations of approximately $113.3 million in 2001,
          $158.0 million in 2002 and $168.1 million in 2003. In addition,
          with respect to the Preferred Securities and Holdings' preferred
          stock currently outstanding, the Company has cash dividend
          obligations of approximately $8.9 million in each of 1998, 1999
          and 2000, $21.5 million in 2001, $57.0 million in 2002 and $70.9
          million in 2003. Accordingly, the Company may have to refinance a
          substantial amount of indebtedness and obtain substantial
          additional funds prior to March 2001, when Holdings is required
          to commence cash interest payments under its senior indebtedness.
          The Company's ability to obtain additional sources of cash will
          depend on, among other things, its financial condition at the
          time, the restrictions in the instruments governing its
          indebtedness and other factors, including market conditions,
          beyond the control of the Company. Additional sources of cash may

                                      13
     <PAGE>

          include public and private equity and debt financings by ICG,
          Holdings and their subsidiaries, sales of non-strategic assets,
          capitalized leases and other financing arrangements. There can be
          no assurance that the Company will be able to refinance such
          indebtedness, including such capitalized leases, or obtain such
          additional funds, and if the Company is unable to effect such
          refinancings or obtain additional funds, the Company's ability to
          make principal and interest payments on its indebtedness,
          including payment of cash dividends on, or the mandatory
          redemption price of, the Preferred Securities, its ability to
          continue as a going concern and the price of the Offered
          Securities will be substantially materially adversely affected.


          RISKS RELATED TO RAPID EXPANSION OF BUSINESS; INTEGRATION OF
          ACQUIRED BUSINESSES

               The continued rapid expansion and development of the
          Company's business will depend on, among other things, the
          Company's ability to successfully implement its sales and
          marketing strategy, evaluate markets, lease fiber, design and
          build fiber backbone routes, secure financing, install
          facilities, acquire rights of way and building access, obtain any
          required government authorizations, implement interconnection to,
          and collocation with, facilities owned by ILECs and obtain
          appropriately priced unbundled network elements from the ILECs,
          all in a timely manner, at reasonable costs and on satisfactory
          terms and conditions. In addition, such expansion may involve
          acquisitions which, if made, could divert the resources and
          management time of the Company and require integration with the
          Company's existing networks and service offerings. See "--Risks
          Related to Local Services and Switched Services Strategies."

               The Company has experienced rapid growth. The Company
          intends to continue to grow through further expansion of its
          existing operations, through acquisitions including the CBG
          Acquisition and the NETCOM Merger, and through the establishment
          of new operations. The Company constantly evaluates acquisition
          opportunities. The Company's ability to manage 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 rapid growth has placed, and its planned future
          growth will continue to 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
          and the establishment of new operations will entail considerable
          expenses in advance of anticipated revenues and may cause
          fluctuations in the Company's operating results.

               In addition, the Company's acquired and new businesses will
          need to be integrated with its existing operations. For acquired
          businesses, including CBG and NETCOM, 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 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 the price of the Offered Securities.


          COMPETITION

               The Company operates in an increasingly competitive
          environment dominated by ILECs such as the Regional Bell
          Operating Companies ("RBOCs") and GTE Corporation ("GTE"). The
          Company's current competitors include RBOCs, GTE, other
          independent ILECs, other CLECs, network systems integration
          service providers, microwave and satellite service providers,
          teleport operators, wireless telecommunications providers and
          private networks of large end users. Potential competitors
          include cable television companies, utilities, ILECs outside
          their current local service areas and the local access operations
          of long distance carriers. Consolidation of telecommunications
          companies, including mergers between certain of the RBOCs, and
          the formation of strategic alliances within the
          telecommunications industry, as well as the development of new
          technologies, could give rise to increased competition. One of
          the primary purposes of the Telecommunications Act is to promote

                                      14
     <PAGE>

          competition, particularly in the local telephone market. Since
          the enactment of the Telecommunications Act, several
          telecommunications companies have indicated their intention to
          aggressively expand their ability to address many segments of the
          telecommunications industry, including segments in which the
          Company participates and expects to participate. For example,
          AT&T Corp., MCI Communications Corp., Time Warner Communications,
          Inc., Texas Utilities Company and other large companies are
          entering the local markets as competitors of the Company. This
          may result in more participants than can ultimately be successful
          in a given market.

               As a recent entrant in the telecom services industry, the
          Company, like other CLECs, has not achieved a significant market
          share. The ILECs have long-standing relationships with their
          customers, have the potential to subsidize services with revenue
          from a variety of businesses and have benefitted from certain
          state and federal regulations that, until recently, favored the
          incumbent operator over potential competitors. The
          Telecommunications Act, other recent state legislative actions,
          and current federal and state regulatory initiatives provide
          increased business opportunities for the Company and others by
          removing or substantially reducing barriers to local exchange
          competition. However, these new competitive opportunities are
          accompanied by potential new competitive opportunities for the
          ILECs, as the Telecommunications Act provides the conditions for
          the removal of previous restrictions on the provision of long
          distance services by the RBOCs. It is also expected that
          increased local competition will result in increased pricing
          flexibility for, and relaxation of regulatory oversight of, the
          ILECs. If the ILECs are permitted to engage in increased volume
          and discount pricing practices or charge CLECs increased fees for
          interconnection to their networks, or if the ILECs seek to delay
          implementation of interconnection to their networks, the
          Company's results of operations and financial condition could be
          adversely affected. In addition, the Company has experienced
          declining access unit prices and increasing price competition for
          access services which to date have been more than offset by
          increasing network usage. The Company expects to continue to
          experience declining prices for the foreseeable future. There can
          be no assurance that the Company will be able to achieve or
          maintain adequate market share or revenue, or compete effectively
          in any of its markets. Any of the foregoing factors could have a
          material adverse effect on the Company and on the price of the
          Offered Securities.

               In addition, the long distance and data transmission
          businesses are extremely competitive and prices have declined
          substantially in recent years and are expected to continue to
          decline.

               Finally, with respect to the NETCOM Merger, when completed,
          the Company will experience substantial competition in providing
          Internet services.


          REGULATION

               The Company operates in an industry that is undergoing
          substantial regulatory change as a result of the passage of the
          Telecommunications Act. The Company's Telecom Services activities
          are regulated by the FCC, state regulatory agencies and
          municipalities. The Company's Satellite Service activities are
          regulated by the FCC and international regulatory bodies.

               The FCC regulates the Company's provision of interstate
          common carrier services, including long distance and data
          services, and the Company's provision of international services.
          The Company currently files and maintains tariffs with the FCC.
          In addition, the FCC and state regulatory bodies are charged with
          implementing the Telecommunications Act, which has a substantial
          impact on the development of the Company's local exchange
          business. The Telecommunications Act is also subject to actions
          of the federal courts, while state regulatory actions are subject
          to review and actions of both state and federal courts. State
          regulatory agencies regulate the Company's provision of local
          dial tone and other intrastate common carrier services. In
          general, the Company is required to obtain certification from the
          relevant state public utilities commissions prior to the
          initiation of intrastate service and is also required to file
          tariffs listing the rates, terms and conditions of intrastate
          services provided. Several states also impose operating
          restrictions on the CLEC industry, covering the ability to raise
          and lower prices and restrictions on marketing and sales
          activities. In addition, local authorities control the Company's

                                      15
     <PAGE>

          access to municipal rights of way. Any failure to maintain proper
          federal and state tariffing or state certification, or
          noncompliance with federal, state or local laws or regulations,
          could have a material adverse effect on the Company.

               The Telecommunications Act generally requires ILECs to
          provide interconnection, nondiscriminatory access to ILEC
          networks, unbundling of ILEC networks and access to ILEC
          operational support systems and network portability. The
          Telecommunications Act imposes a variety of new duties on the
          ILECs in order to promote network competition in the markets for
          local exchange and access services, including the duty to
          negotiate in good faith with competitors requesting
          interconnection to the ILEC networks. However, negotiations with
          each ILEC have sometimes involved considerable delays and the
          resulting negotiated agreements may not necessarily be obtained
          on terms and conditions that are desirable to the Company. In
          such instances, the Company has petitioned the proper state
          regulatory agency to arbitrate disputed issues. In addition,
          following state review either party in the negotiations can
          appeal to the federal courts. There can be no assurance that the
          Company will be able to negotiate acceptable new interconnection
          agreements with ILECs or that, if state regulatory authorities
          impose terms and conditions on the parties in arbitration, such
          terms will be acceptable to the Company.

               On August 8, 1996, the FCC adopted rules and policies
          implementing the interconnection provisions of the
          Telecommunications Act, which rules, in general, are favorable to
          new competitive entrants. The FCC's rules were challenged in the
          federal courts of appeals by GTE, the RBOCs, other large
          independent ILECs and state regulatory commissions. On July 18,
          1997, the U.S. Court of Appeals for the Eighth Circuit (the
          "Eighth Circuit Court") issued a ruling that vacated certain of
          the FCC's rules and upheld the FCC's rules on other issues.

               In the July 18, 1997 decision, the Eighth Circuit Court
          ruled that state commissions, not the FCC, have jurisdiction over
          the pricing of interconnection, unbundled network elements and
          resale services. The Eighth Circuit Court also ruled that the
          FCC's interpretation of Section 252(i) of the Telecommunications
          Act, the so-called "pick and choose" provision, was incorrect.
          The Eighth Circuit Court held that the Telecommunications Act
          allows CLECs to adopt whole interconnection agreements negotiated
          by other competitors but not to "pick and choose" pieces of
          existing agreements.

               Because the Eighth Circuit Court held that CLECs cannot
          "pick and choose" pieces of other interconnectors' negotiated
          interconnection agreements, the Company may be subject to the
          risk that other CLECs negotiate more favorable prices, terms or
          conditions with the ILECS. The Company's only recourse under such
          circumstances may be to adopt other interconnectors' agreements
          with an ILEC in whole, though these agreements may include terms
          and conditions the Company finds unacceptable. The Eighth Circuit
          Court upheld certain of the FCC's rules regarding unbundled
          network elements. Moreover, the Eighth Circuit Court's decision
          does not alter most of the basic statutory requirements of the
          Telecommunications Act, including the statutory requirements that
          the ILECs conduct negotiations and enter into interconnection
          agreements with competitive carriers.

               The FCC (and other parties) have announced their intention
          to seek Supreme Court review of the Eighth Circuit Court's
          decision. Additionally, separate petitions for rehearing were
          filed with the Eighth Circuit Court by a group of interexchange
          carriers ("IXCs"), two groups of ILECs and a group of CLECs. On
          October 14, 1997 the Eighth Circuit Court granted the ILEC
          petitions for rehearing, and denied the CLEC and IXC petitions.
          The Court's decision on rehearing vacated an additional FCC rule
          that addressed the ability of new entrants to purchase ILEC
          network elements at cost-based rates on a bundled rather than an
          unbundled basis. Management believes the Company could benefit
          from a reversal in whole, or in part, of the Eighth Circuit
          Court's decision.

               Although the Company believes that the Telecommunications
          Act and other state and federal regulatory initiatives that favor
          increased competition are advantageous to the Company, there can
          be no assurance that changes in current or future state or
          federal regulations, including changes that may result from
          further court review of the FCC's interconnection rules, or
          increased competitive opportunities resulting from such changes,
          will not have a material adverse effect on the Company and on the
          price of the Offered Securities.

                                      16

               The Company must obtain and maintain certain FCC
          authorizations for its satellite and wireless services. The
          Company currently provides maritime communication services
          pursuant to an experimental license and a grant of Special
          Temporary Authority ("STA"). The Company's experimental license
          has been renewed by the FCC on several occasions. In January
          1997, the Company submitted an application for the modification
          and renewal of the experimental license, which was due to expire
          on February 1, 1997. Under the FCC's procedures, the experimental
          license has remained valid pending FCC action on the renewal and
          modification. On January 30, 1997, the Company was granted the
          STA for which the Company filed for a six-month extension on
          July 25, 1997. The Company has received a verbal grant of the
          extension. Although the Company expects that the FCC will issue a
          permanent license, there can be no assurance the Company will be
          granted a permanent license, that the experimental license
          currently being used to provide maritime services will be renewed
          for a further term or that any license granted by the FCC will
          not require substantial payments by the Company.

               The FCC and relevant state public utilities commissions have
          the authority to regulate interstate and intrastate telephone
          rates, respectively, ownership of transmission facilities and the
          terms and conditions under which certain of the Company's
          services are provided. Federal and state regulations and
          regulatory trends have had, and in the future are likely to have,
          both positive and negative effects on the Company and its ability
          to compete. The recent trend in both federal and state regulation
          of telecommunications service providers has been in the direction
          of reduced regulation. In general, neither the FCC nor the
          relevant state public utilities commission currently regulate the
          Company's long distance rates or profit levels, although either
          or both may do so in the future. There can be no assurance that
          changes in current or future federal or state regulations or
          future judicial changes would not have a material adverse effect
          on the Company.


          SIGNIFICANT CAPITAL REQUIREMENTS 

               The Company's current plans for expansion of existing
          networks, the development of new networks, the further
          development of the Company's products and services and the
          continued funding of operating losses may require additional cash
          from outside sources. The Company's arrangements with utilities
          require it to make significant cash payments and the development
          of the Company's networks requires significant capital
          expenditures for transmission equipment, switching and network
          build-out from the utilities' fiber backbone to end user
          locations. The Company must also purchase a substantial amount of
          equipment and other assets from vendors. The Company anticipates
          that the expansion of existing networks, construction of new
          networks and further development of the Company's products and
          services will require capital expenditures of approximately $66.0
          million during the last quarter of 1997 and approximately $300.0
          million in 1998, and continued significant capital expenditures
          thereafter. Further, the Company has significant personnel
          expenses related to increasing its marketing efforts and offering
          new long distance and planned data transmission services in
          anticipation of revenue growth. The Company also plans to make
          strategic acquisitions from time to time. The Company anticipates
          that its substantial cash requirements will continue into the
          foreseeable future. Additional sources of cash may include public
          and private equity and debt financings of ICG, Holdings or their
          subsidiaries, sales of non-strategic assets, capitalized leases
          and other financing arrangements. There can be no assurance that
          additional financing will be available to the Company or, if
          available, that it can be obtained on terms acceptable to the
          Company. Failure to obtain such financing could result in the
          delay or abandonment of some or all of the Company's acquisition,
          development and expansion plans and expenditures, which could
          have a material adverse effect on its business prospects and
          limit the Company's ability to fund the mandatory redemption
          price of the Preferred Securities by redeeming the ICG Preferred
          Stock for cash.


          DEPENDENCE ON KEY CUSTOMERS 

               The Company's five largest customers accounted for
          approximately 28%, 30% and 28% of the Company's consolidated
          revenue in fiscal 1996, the three months ended December 31, 1996
          and the nine months ended September 30, 1997, respectively. The
          loss of, or decrease of business from, one or more of these

                                      17
     <PAGE>

          customers could have a material adverse effect on the business,
          financial condition and results of operations of the Company.
          While the Company actively markets its products and services,
          there can be no assurance that the Company will be able to
          attract new customers or retain its existing customers.


          RISKS OF ENTRY INTO LONG DISTANCE BUSINESS 

               In order to offer its end user customers a complete package
          of telecommunications services, the Company recently began
          offering long distance services. Although the Company has
          extensive experience in the telecommunications business,
          including an executive team with sales, marketing and long
          distance management expertise, the Company has limited experience
          providing long distance services. The long distance business is
          extremely competitive and prices have declined substantially in
          recent years and are expected to continue to decline. The Company
          does not expect long distance services to generate a material
          portion of its revenues over the near term.

               The Company relies on other carriers to provide transmission
          and termination services for a majority of its long distance
          traffic and will therefore be dependent on such carriers. The
          Company has entered into agreements with long distance carriers
          to provide it with long distance transmission services. Such
          agreements typically provide for the resale of long distance
          services on a per minute basis (some with minimum volume
          commitments). Where the Company anticipates higher volumes of
          traffic, it may lease point-to-point circuits on a monthly or
          longer term fixed cost basis. The negotiation of these agreements
          involves estimates of future supply and demand for long distance
          telecommunications transmission capacity. Should the Company fail
          to meet its minimum volume commitments, if any, pursuant to these
          agreements, it may be obligated to pay underutilization charges.
          Likewise, the Company may underestimate its need for long
          distance facilities and therefore be required to obtain the
          necessary transmission capacity through more expensive means.
          There can be no assurance that the Company will acquire long
          distance capacity on favorable terms or that the Company can
          accurately predict long distance prices and volumes so that it
          can generate positive gross margins. The success of the Company's
          entry into the long distance business will be dependent upon,
          among other things, the Company's ability to select new equipment
          and software and integrate these into its networks, hire and
          train qualified personnel, enhance its billing, back-office and
          information systems to accommodate long distance services and the
          acceptance of potential customers of the Company's long distance
          service offerings. If the Company's long distance transmission
          business fails to generate positive gross margins or if the
          Company fails in any of the foregoing respects, such failure may
          have a material adverse effect on the Company's business and the
          price of the Offered Securities. In addition, a majority of the
          Company's Telecom Services revenue is derived from long distance
          carrier customers. The Company is subject to the risk that its
          entry into the long distance business will adversely affect its
          relationship with its long distance carrier customers.


          RISKS OF ENTRY INTO DATA TRANSMISSION BUSINESS 

               To complement its telecommunications services offerings the
          Company began offering frame relay services in California,
          Colorado and Ohio during the first quarter of 1997. These
          services are targeted at the Company's existing customers and
          other businesses with substantial data communications
          requirements. To date, the Company has not generated any revenue
          from these services, despite having offered these services since
          the first quarter of 1997. Based on this market experience, the
          Company is reevaluating its previous product and customer
          strategies, and expects to generate low or negative gross margins
          and substantial start-up expenses as it develops and rolls out
          its data services. The Company does not expect data transmission
          services to generate a material portion of its revenue over the
          near term.

               Although the Company has extensive experience in the
          telecommunications business, the Company has no direct experience
          providing data transmission services. Additionally, the data
          transmission business is extremely competitive and prices have
          declined substantially in recent years and are expected to

                                      18
     <PAGE>

          continue to decline. In providing these services, the Company
          will be dependent upon vendors for assistance in the planning and
          deployment of its initial data product offerings as well as
          ongoing training and support. The success of the Company's entry
          into the data transmission business will be dependent upon, among
          other things, the Company's ability to select new equipment and
          software and integrate these into its networks, hire and train
          qualified personnel, enhance its billing, back-office and
          information systems to accommodate data transmission services and
          customer acceptance of the Company's data services. No assurance
          can be given that the Company will be successful with respect to
          these matters. If the Company is not successful with respect to
          these matters, there may be a material adverse effect on the
          Company's business and the price of the Offered Securities.


          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. Billing and information systems for the Company's
          historical lines of business have been produced largely in-house
          with partial reliance on third party vendors. These systems have
          generally met the Company's needs due in part to the Company's
          low volume of bills and orders. As the Company commences
          providing local, long distance and data transmission services,
          the need for sophisticated billing and information systems is
          increasing significantly. The Company's current local billing
          platform plans rely on products and services provided by third
          party vendors. Additionally, the Company is developing automated
          systems and customer service centers to provision orders.
          Information systems are vital to the success of these centers,
          and the information systems for these centers are largely being
          developed by third party vendors.

               San Francisco Consulting Group ("SFCG") has been engaged by
          the Company to recommend a long-term customer care and billing
          solution, to provide support in development of short to long-term
          information systems planning and to facilitate and improve the
          provisioning process. The services provided by SFCG focus
          primarily on further development of the Company's abilities to
          ensure that back-office processes and functions operate at
          maximum effectiveness. 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 the Company to reach its objectives, and
          on its financial condition and results of operations.

               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 the price of the Offered Securities.


          RISKS RELATED TO JOINT VENTURES AND STRATEGIC ALLIANCES

               The Company has formed a strategic alliance with CSW for the
          purpose of providing services, through ChoiceCom, in Austin,
          Corpus Christi, Dallas, Houston and San Antonio, Texas. Under the
          terms of this arrangement, CSW holds a 100% interest in ChoiceCom
          and the Company has an option to purchase a 50% interest. Under
          the terms of certain of its indebtedness, the Company is
          currently prohibited from making any investment in ChoiceCom
          (other than a $15.0 million debt investment that the Company has
          committed to make, of which approximately $6.4 million was
          advanced as of September 30, 1997) and from purchasing less than
          a majority interest in any venture. Unless the terms of certain
          of the Company's indebtedness are revised (which could entail
          substantial costs), the Company may not be able to exploit
          opportunities for joint ventures, which could have an adverse
          effect on the Company and the price of the Offered Securities.

                                      19
     <PAGE>

               The Company has also formed strategic alliances with utility
          companies to lease fiber optic facilities. The Company expects to
          continue to enter into strategic alliances, joint ventures and
          other similar arrangements in the future. The other parties to
          such existing arrangements, and to arrangements in which the
          Company may subsequently participate, may at any time have
          economic, business or legal interests or goals that are
          inconsistent with those of the strategic alliance, joint venture
          or similar arrangement or those of the Company. In addition, a
          joint venture partner may be unable to meet its economic or other
          obligations to the venture, which, depending upon the nature of
          such obligations, could adversely affect the Company and the
          price of the Offered Securities.


          RAPID TECHNOLOGICAL CHANGE

               The telecommunications industry is subject to rapid and
          significant changes in technology. The effect of technological
          changes, including changes relating to emerging wireline and
          wireless transmission technologies, on the business of the
          Company cannot be predicted.


          DEPENDENCE ON RIGHTS OF WAY AND OTHER THIRD PARTY AGREEMENTS

               The Company must obtain easements, rights of way, franchises
          and licenses from various private parties, including actual and
          potential competitors, and local governments in order to
          construct and maintain fiber optic networks. There can be no
          assurance that the Company will obtain rights of way and
          franchise agreements to expand its networks or that these
          agreements will be on terms acceptable to the Company, or that
          current or potential competitors will not obtain similar rights
          of way and franchise agreements. Because certain of these
          agreements are short-term or are terminable at will, there can be
          no assurance that the Company will continue to have access to
          existing rights of way and franchises after the expiration of
          such agreements. An important element of the Company's strategy
          is to enter into long-term agreements with utilities to take
          advantage of their existing facilities and to license or lease
          their excess fiber capacity. The Company has entered into
          contracts and is negotiating agreements with other utilities.
          However, other CLECs are seeking to enter into similar
          arrangements and have bid and are expected to continue to bid
          against the Company for future licenses or leases. Furthermore,
          utilities are required by state or local regulators to retain the
          right to "reclaim" fiber licensed or leased to the Company if
          such fiber is needed for the utility's core business. There can
          be no assurance that the Company will be able to obtain
          additional licenses or leases on satisfactory terms or that such
          arrangements will not be subject to reclamation. If a franchise,
          license or lease agreement was terminated and the Company was
          forced to remove or abandon a significant portion of its network,
          such termination could have a material adverse effect on the
          Company and the price of the Offered Securities.


          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 loss of certain key personnel could
          adversely affect the Company and the price of the Offered
          Securities.


          NO DIVIDENDS

                                      20
     <PAGE>

               The Company does not expect to generate net income in the
          near future and, therefore, does not anticipate paying cash
          dividends on the Common Stock. The payment of any future
          dividends on the Common Stock is effectively prohibited by the
          indentures for certain of Holdings' senior indebtedness.


          POSSIBLE STOCK PRICE VOLATILITY

               The price of the Common Stock has been, and is expected to
          continue to be, highly volatile. Factors such as legislation or
          regulation, variations in the Company's revenue, earnings and
          cash flow, the difference between the Company's actual results
          and the results expected by investors and analysts and
          announcements of new service offerings, marketing plans or price
          reductions by the Company or its competitors, technological
          innovations, mergers or strategic alliances, may cause the price
          of Common Stock to fluctuate substantially. In addition, the
          stock markets recently have experienced significant price and
          volume fluctuations that have affected growth companies such as
          telecommunications concerns. The fluctuations in the market
          prices of the stocks of many companies have not been directly
          related to the operating performance of those companies. Such
          market fluctuations may materially adversely affect the price of
          the Common Stock and the Preferred Securities.


          NO OPERATIONS OF FUNDING

               The issuer of the Preferred Securities, Funding, is a
          special purpose subsidiary of ICG which is a newly formed
          Delaware limited liability company with no operations or assets
          other than the agreement to purchase ICG Preferred Stock,
          Treasury Strips and other government securities purchased with
          the proceeds of the Original Offering. Funding will have no other
          funds to pay cash dividends. In order to pay subsequent
          dividends, Funding will be dependent on ICG to provide it with
          cash (which is currently prohibited by the terms of ICG's
          indebtedness) or to issue it Common Stock (which is required by
          the terms of the ICG Preferred Stock). Funding's assets will
          consist almost entirely of its interest in the ICG Preferred
          Stock and the Treasury Strips.


          NO PRACTICAL BENEFIT TO HOLDERS FROM THE GUARANTEE

               ICG will guarantee the payment in full to the holders of the
          Preferred Securities of (i) accrued and unpaid dividends on the
          Preferred Securities, if and only to the extent Funding has funds
          sufficient to make such payment therefor, (ii) the redemption
          price with respect to the Preferred Securities redeemed, if and
          only to the extent Funding has funds sufficient to make such
          payment and (iii) upon a voluntary termination or involuntary
          dissolution, winding-up or termination of Funding (other than in
          connection with a redemption of all of the Preferred Securities),
          the lesser of (a) the aggregate of the liquidation preference and
          all accrued and unpaid dividends on the Preferred Securities to
          the date of payment, to the extent Funding has funds sufficient
          to make such payment, and (b) the amount of assets of Funding
          remaining available for distribution to holders of the Preferred
          Securities upon liquidation of Funding. Such guarantee will also
          be subject to the contractual restrictions contained in the
          indentures (the "Indentures") for ICG's outstanding high yield
          notes. The Indentures currently effectively prohibit any cash
          payment on the Guarantee.

               Because the Guarantee is limited to the amount of the funds
          held by Funding and is currently limited by the provisions of the
          Indentures, the Guarantee is of no practical benefit to holders
          of the Preferred Securities.


          RANKING OF ICG PREFERRED STOCK; PRIOR PAYMENT OBLIGATIONS OF ICG 

               The ICG Preferred Stock will be subordinated to all existing
          and future indebtedness and other liabilities of ICG and its
          subsidiaries, and will, with respect to dividend distributions
          and distributions upon the liquidation, winding-up or dissolution

                                      21
     <PAGE>

          of ICG, rank senior to all Common Stock and senior to or pari
          passu with all other capital stock of ICG. There are no terms in
          the ICG Preferred Stock, the Preferred Securities or the
          Guarantee that limit ICG's ability to incur additional
          indebtedness or issue pari passu or junior preferred stock. As of
          September 30, 1997, the Company had approximately $940.9 million
          of accreted indebtedness outstanding and approximately $281.9
          million of preferred stock of Holdings outstanding. The
          outstanding preferred stock of Holdings is effectively senior to
          the ICG Preferred Stock. All of such indebtedness and preferred
          stock must be repaid or refinanced prior to the mandatory
          redemption of the Preferred Securities. Any securities issued to
          refinance such indebtedness and preferred stock may prohibit the
          redemption of the ICG Preferred Stock for cash, thus effectively
          prohibiting the redemption of the Preferred Securities for cash.
          See "- Substantial Indebtedness."

          ABSENCE OF PUBLIC MARKET FOR THE PREFERRED SECURITIES; VOLATILITY
          OF COMMON STOCK PRICE 

               The Preferred Securities are a new issue of securities for
          which there is currently no active trading market. If the
          Preferred Securities 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, the market price of Common Stock and other factors,
          including general economic conditions and the financial
          condition, performance of, and prospects for the Company. Because
          the Preferred Securities are being sold pursuant to an exemption
          from registration under applicable securities laws and,
          therefore, may not be publicly offered, sold or otherwise
          transferred in any jurisdiction where such registration may be
          required, no public market for such securities will develop. If
          an active market for the Preferred Securities fails to develop or
          be sustained, the trading price of such Preferred Securities
          could be materially adversely affected. If such a market were to
          develop, the Preferred Securities could trade at prices that may
          be higher or lower than the initial offering price depending on
          many factors, including prevailing interest rates, the price of
          the Common Stock, the Company's operating results, and the market
          for similar securities.


          CERTAIN UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

          Partnership Status

               Funding's ability to pay dividends on Preferred Securities
          depends, in part, on the classification of Funding as a
          partnership for federal income tax purposes. Assuming the
          accuracy of certain factual matters as to which Funding has made
          representations, counsel is of the opinion that, under current
          law, Funding will be classified as a partnership for federal
          income tax purposes. No ruling from the Internal Revenue Service
          (the "IRS") as to classification has been or is expected to be
          requested. Instead, Funding intends to rely on such opinion of
          counsel (which is not binding on the IRS).

               If Funding were classified as an association taxable as a
          corporation for federal income tax purposes, Funding would pay
          tax on its income at corporate rates (currently a 35% federal
          rate), distributions would generally be taxed again to the
          holders of Preferred Securities as corporate distributions, and
          no income, gains, losses or deductions would flow through to the
          holders of Preferred Securities. Because a tax would be imposed
          upon Funding as an entity, the cash available for distribution to
          the holders of Preferred Securities would be substantially
          reduced. Treatment of Funding as an association taxable as a
          corporation or otherwise as a taxable entity would result in a
          material reduction in the anticipated cash flow and after-tax
          return of the holders of Preferred Securities and thus would
          likely result in a substantial reduction in the value of
          Preferred Securities.


          Funding Allocations 

               It is possible that a holder may receive allocations of
          income resulting from deemed distributions to Funding without
          matching cash distributions. Furthermore, a holder who disposes

          of Preferred Securities between record dates for dividends will
          be required pursuant to Funding's method of allocation to include
          its pro rata share of Funding's income (and deductions) through
          the end of the month that such disposition occurs in income (and
          to add such amount to the adjusted tax basis in the holder's
          Preferred Securities) without receiving the dividend for the
          quarter in which such disposition occurs. Furthermore, certain
          allocation methods of Funding may be challenged by the IRS, which
          may result in greater tax liability to holders of Preferred
          Securities during their period of ownership or upon disposition.


          Disposition of Preferred Securities

               A holder who sells Preferred Securities will recognize gain
          or loss equal to the difference between the amount realized and
          his adjusted tax basis in such Preferred Securities. Thus, prior
          Funding distributions in excess of cumulative net taxable income
          in respect of Preferred Securities which decreased a holder's tax
          basis in such Preferred Securities will, in effect, become
          taxable income if the Preferred Securities are sold at a price
          greater than the holder's tax basis in such Preferred Securities,
          even if the price is less than his original cost. To the extent
          the selling price is less than the holder's adjusted tax basis, a
          holder will recognize a capital loss. Subject to certain limited
          exceptions, capital losses cannot be applied to offset ordinary
          income for United States federal income tax purposes.


          LIMITED VOTING RIGHTS

               Generally, holders of the Preferred Securities do not have
          any voting rights. However, the vote of a majority of the
          Preferred Securities is required to approve any amendment to the
          Operating Agreement or any proposed action by Funding that would
          (i) have a material adverse effect on the powers, preferences or
          special rights of the holders of the Preferred Securities or (ii)
          cause the dissolution, winding-up or termination of Funding. The
          approval of the holders of a majority of the ICG Preferred Stock
          is required to approve any change to ICG's charter or any
          proposed action by ICG that would (i) have a material adverse
          effect on the powers, preferences or special rights of the holder
          of the ICG Preferred Stock or (ii) cause the dissolution,
          winding-up or termination of Funding. Funding is expected to be
          the sole holder of the ICG Preferred Stock. Funding has agreed
          not to grant such approval without the consent of the holders of
          a majority of the Offered Securities then outstanding.


          COMMON STOCK ELIGIBLE FOR FUTURE SALE

               As of September 30, 1997, there were 32,413,010 shares of
          Common Stock outstanding, all of which are transferable without
          restriction or further registration under the Securities Act,
          except for any shares of Common Stock held by affiliates of ICG,
          which will be subject to the resale limitations of Rule 144
          promulgated under the Securities Act ("Rule 144"). In addition,
          ICG has reserved and registered under the Securities Act the
          following 9,219,802 shares of Common Stock for future issuance:
          (i) 1,981,914 shares of Common Stock issuable pursuant to
          Holdings-Canada warrants; (ii) 3,373 shares of Common Stock
          issuable upon conversion of the remaining interest on the
          Company's 7% Convertible Subordinated Notes; (iii) 4,923,011
          shares of Common Stock issuable pursuant to outstanding options,
          with exercise prices ranging from $2.92 to $25.00 per share; (iv)
          424,511 shares of Common Stock reserved for issuance under ICG's
          401(k) Plan; (v) 250,000 shares of Common Stock reserved for
          issuance upon the exercise of Series A Warrants, with an exercise
          price of $7.94 per share; (vi) 250,000 Shares of Common Stock
          reserved for issuance upon the exercise of the Series B Warrants,
          with an exercise price of $8.73 per share; (vii) 949,911 shares
          of Common Stock reserved for issuance pursuant to ICG's 1996
          Employee Stock Purchase Plan, (viii) 405,382 shares of Common
          Stock reserved for issuance under the 1996 Stock Option Plan; and
          (ix) 31,700 shares of Common Stock which may be issued upon the
          exchange of an equal number of shares of Class A Common Shares of
          Holdings-Canada. On October 17, 1997, the Company sold 687,221

                                      23
     <PAGE>

          shares of Common Stock to certain shareholders of CBG. In
          addition, Funding may sell Common Stock to fund dividends on the
          Preferred Securities. Further, upon the completion of the NETCOM
          Merger, approximately 10.1 million shares of Common Stock,
          subject to adjustment and subject to the exercise of options for
          NETCOM common stock prior to the effective time of the NETCOM
          Merger, and assuming a share exchange ratio of 0.8628, will be
          issued to the holders of NETCOM common stock in exchange for
          their shares. As of September 30, 1997, NETCOM had outstanding
          employee and director stock options, which if outstanding upon
          consummation of the NETCOM Merger, and assuming a share exchange
          ratio of 0.8628, will convert to options to purchase 1,564,599
          shares of Common Stock. Sales or the expectation of sales of
          substantial numbers of Common Stock in the public market could
          adversely affect the prevailing market prices for the Offered
          Securities.


          ANTI-TAKEOVER PROVISIONS

               Certain provisions of ICG's Certificate of Incorporation and
          the corporate charters and debt instruments of its subsidiaries
          may have the effect of deterring transactions involving a change
          in control of ICG, including transactions in which stockholders
          might receive a premium for their shares. ICG's Certificate of
          Incorporation provides that directors serve staggered three-year
          terms and authorizes the issuance of up to 1,000,000 shares of
          preferred stock with such designations, rights and preferences as
          may be determined from time to time by ICG's Board of Directors.
          In addition, the corporate charter(s) of Holdings and Holdings-
          Canada authorize the issuance of up to 1,000,000 and 30,000,000
          shares of preferred stock, respectively, with such designations,
          rights and preferences as may be determined by the Board of
          Directors of Holdings and Holdings-Canada, respectively. The
          staggered board provision increases the likelihood that, in the
          event of a takeover of ICG, incumbent directors would retain
          their positions and, consequently, may have the effect of
          discouraging, delaying or preventing a change in control or
          management of ICG. The authorization of preferred shares empowers
          the Board of Directors, without further shareholder approval, to
          issue preferred shares with dividend, liquidation, conversion,
          voting or other rights which could adversely affect the voting
          power or other rights of the holders of the Common Stock. In the
          event of issuance, the preferred shares could be utilized, under
          certain circumstances, as a method of discouraging, delaying or
          preventing a change of control of ICG. In addition, the Company
          is, and will continue to be, subject to the anti-takeover
          provisions of the Delaware General Corporation Law, which could
          have the effect of delaying or preventing a change of control of
          the Company. Furthermore, upon a change of control, the holders
          of substantially all of the Company's outstanding indebtedness
          are entitled, at their option, to be repaid in cash and the
          holders of Holdings' preferred stock may, at their option,
          require Holdings to redeem their shares for cash. Such provisions
          may have the effect of delaying or preventing changes in control
          or management of the Company. All of these factors could
          materially adversely affect the price of the Offered Securities.

                                   USE OF PROCEEDS

               The Selling Holders will receive all of the proceeds from
          any sale of the Offered Securities. Neither ICG nor Funding will
          receive any proceeds from the sale of the Offered Securities.


                       FINANCIAL INFORMATION REGARDING FUNDING

               Funding's financial statements have been consolidated with
          the Company's unaudited consolidated financial statements for the
          nine months ended September 30, 1997, which are incorporated by
          reference herein.  The Preferred Securities are included in the
          Company's unaudited consolidated balance sheet as redeemable
          preferred securities of subsidiaries.  Funding has no liabilities
          or operations and its sole assets are the net proceeds from the
          offering of the Preferred Securities, which have been invested
          entirely in Treasury Strips and U.S. government securities.  The
          terms of the Preferred Securities require Funding to use the
          principal and earnings on the Treasury Strips for the payment of
          the first 13 cash dividends on the Preferred Securities and to use
          the principal and earnings on the U.S. government securities to
          purchase the ICG Preferred Stock on the Funding Date (as defined
          herein). See "Description of the Preferred Securities -
          Provisional Redemption by Funding."

               The following table sets forth the Company's ratio of
          earnings to combined fixed charges and preferred stock dividends
          on a historical basis for each fiscal year in the five-year

          stock dividends consist of interest charges and amortization of debt
          expense and discount or premium related to indebtedness, whether
          expensed or capitalized, that portion of rental expense the Company
          believes to be representative of interest (i.e., one-third of rental
          expense) and preferred stock dividends.

                       DESCRIPTION OF THE PREFERRED SECURITIES

               The following summary of certain material terms and
          provisions of the Preferred Securities does not purport to be
          complete and is subject to, and qualified in its entirety by
          reference to, the Certificate of Formation, the Operating
          Agreement and the Written Action of the Manager of ICG Funding,
          LLC, dated as of September 24, 1997 (the "Written Action"), with
          respect to the terms of the Preferred Securities, copies of which
          are available upon request to ICG. Capitalized terms not
          otherwise defined herein have the meanings assigned to them in
          the Operating Agreement of Funding.


          GENERAL

               Funding has issued 2.645 million Preferred Securities. The
          Preferred Securities do not have any subscription or preemptive
          rights related thereto. American Stock Transfer and Trust
          Company, 40 Wall Street, 46th floor, New York, New York 10005, is
          transfer agent and registrar (the "Transfer Agent") for the
          Preferred Securities.


          RANKING

               The Preferred Securities, with respect to dividend
          distributions and distributions upon the liquidation, winding-up
          or dissolution of Funding, rank senior to all classes of common
          securities of Funding and to each other class of capital
          securities or series of preferred securities of Funding. The
          Operating Agreement of Funding does not permit Funding to incur
          any indebtedness or liabilities or issue any securities except
          for the issuance of the Preferred Securities and obligations to
          the holders thereof.


          ESCROW

               Pursuant to an Escrow Agreement dated as of the Original
          Closing Date (the "Escrow Agreement"), among Funding, ICG and
          Norwest Bank Colorado, National Association, as escrow agent (the
          "Escrow Agent"), on the Original Closing Date, Funding used a
          portion of the proceeds from the Original Offering to purchase
          Treasury Strips in an amount sufficient to fund the cash payment
          of the first 13 dividends. The Treasury Strips were pledged to
          the Escrow Agent for the benefit of the holders of the Preferred
          Securities pursuant to the Escrow Agreement and will be held by
          the Escrow Agent in the Escrow Account (as defined below).
          Pursuant to the Escrow Agreement, immediately prior to a Dividend
          Payment Date (through and including November 15, 2000) the Escrow
          Agent will release from the Escrow Account amounts sufficient to
          pay the dividend then due on the Preferred Securities.

               Under the Escrow Agreement, once Funding makes the dividend
          payments on the Preferred Securities through and including
          November 15, 2000 (or, in the event of a Provisional Redemption,
          upon the making of the Dividend Make-Whole Payment), all of the
          remaining Treasury Strips, if any, will be released from the
          Escrow Account. "Escrow Account" means the account established
          with the Escrow Agent pursuant to the terms of the Escrow
          Agreement for the deposit of the Treasury Strips (and earnings
          thereon and proceeds thereof) purchased by Funding with a portion
          of the net proceeds from the sale by Funding of the Preferred
          Securities. The summary does not purport to be complete and is
          subject in all respects to, and is qualified in its entirety by
          reference to, the Escrow Agreement, a copy of which is available
          from ICG upon request.

                                      26
     <PAGE>


          DIVIDENDS

               Holders of Preferred Securities will be entitled to receive
          dividends on the Preferred Securities at the rate of 6 3/4% per
          annum of the liquidation preference of Preferred Securities,
          payable quarterly. All dividends will be cumulative, whether or
          not earned or declared, on a daily basis from the Original
          Closing Date and will be payable quarterly in arrears on
          February 15, May 15, August 15 and November 15 of each year,
          commencing on November 15, 1997 (to holders of record at the
          close of business on February 1, May 1, August 1 and November 1
          immediately preceding the Dividend Payment Date). Through and
          including November 15, 2000, dividends on the Preferred
          Securities will be paid in cash. Thereafter, dividends on the
          Preferred Securities may be paid at Funding's option, in (i)
          cash, (ii) Common Stock, based upon 90% of the Average Market
          Value of the Common Stock or (iii) any combination of cash or
          Common Stock; provided that any dividend payment must be made in
          cash to the extent ICG shall have provided Funding with cash
          (whether through dividends on the ICG Preferred Stock or
          otherwise) to make all or any portion of such dividend payment
          with respect to the Preferred Securities. The Indentures
          effectively prohibit ICG from providing cash to Funding (except
          as a result of Funding selling Common Stock). If any dividend (or
          portion thereof) payable in cash on any Dividend Payment Date is
          not declared or paid in full in cash on such Dividend Payment
          Date, the amount of such dividend that is payable and that is not
          paid in cash on such date will cumulate at the dividend rate,
          compounding quarterly, until declared and paid in full.

               Dividends on the Preferred Securities will be paid to the
          extent that Funding has funds legally available for the payment
          of such dividends. Amounts available to Funding for dividends to
          the holders of the Preferred Securities will be limited to shares
          of Common Stock received by Funding from ICG as dividends on the
          ICG Preferred Stock (and proceeds from any sales of such Common
          Stock by Funding) and the interest on and principal of the
          Treasury Strips that are held in the Escrow Account. The ICG
          Preferred Stock provides that ICG shall pay dividends to Funding,
          payable in Common Stock, in an amount sufficient to allow Funding
          to pay dividends on the Preferred Securities in full. Any such
          Common Stock received by Funding may be paid as a dividend to the
          holders of the Preferred Securities or sold in the open market
          and the cash proceeds of sale would be used to pay cash dividends
          on the Preferred Securities.


          EXCHANGE RIGHTS

               General. The Preferred Securities are exchangeable at any
          time, in whole or in part, prior to the Mandatory Redemption Date
          (unless earlier redeemed), at the option of the holder thereof
          and in the manner described below, into shares of Common Stock at
          an initial exchange rate of 2.0811 shares of Common Stock for
          each Preferred Security (equivalent to an exchange price of
          $24.025 per share of Common Stock), subject to adjustment as
          described under "--Exchange Rights--Exchange Rate Adjustments"
          below, or an aggregate of 4,786,680 shares of Common Stock (based
          on the exchange rate on the Original Closing Date).

               A holder of a Preferred Security wishing to exercise its
          exchange right shall (i) deliver an exchange notice to the
          Exchange Agent, (ii) if required, furnish appropriate
          endorsements and transfer documents and (iii) if required, pay
          all transfer or similar taxes, and the Exchange Agent shall, on
          behalf of such holder, exchange such Preferred Securities with
          Funding for shares of Common Stock and deliver such shares of
          Common Stock to such holder. Generally, such exchange with
          Funding, in whole or in part, should not be a taxable event to
          the holder. ICG will initially act as Exchange Agent. Holders may
          obtain copies of the required form of the exchange notice from
          the Exchange Agent.

               Holders of Preferred Securities at the close of business on
          a dividend record date will be entitled to receive the dividends
          payable on such Preferred Securities on the corresponding
          Dividend Payment Date notwithstanding the exchange of such
          Preferred Securities following such dividend record date but
          prior to such Dividend Payment Date. Except as provided in the
          immediately preceding sentence, neither Funding nor ICG will
          make, or be required to make, any payment, allowance or
          adjustment for accumulated and unpaid dividends, whether or not
          in arrears, on exchanged Preferred Securities. Each exchange will
          be deemed to have been effected immediately prior to the close of
          business on the day on which the related exchange notice was
          received by the Exchange Agent.

                                      27
    <PAGE>

               No fractional shares of Common Stock will be issued as a
          result of exchange, but in lieu thereof such fractional interest
          will be paid by Funding in cash based on the last reported sale
          price of Common Stock on the date Preferred Securities are
          surrendered for exchange. From time to time, Funding will sell
          shares of Common Stock in the open market and will use proceeds
          from such sales to pay cash on the fractional interests described
          in the prior sentence.

               Exchange Rate Adjustments. The exchange rate is subject to
          adjustment upon certain events occurring after the Original
          Closing Date, including (i) the issuance of Common Stock as a
          dividend or distribution on the Common Stock; (ii) certain
          subdivisions and combinations of the Common Stock; (iii) the
          issuance to holders of Common Stock of certain rights or warrants
          entitling them to subscribe for or purchase Common Stock at less
          than the Average Market Value; (iv) the distribution to all
          holders of Common Stock of capital stock (other than Common
          Stock) or evidences of indebtedness of ICG or of assets (other
          than cash distributions covered by clause (v) below) or rights or
          warrants to subscribe for or purchase any of its securities
          (excluding rights or warrants to purchase Common Stock referred
          to in clause (iii) above); (v) distributions consisting of cash,
          excluding any quarterly cash dividend on the Common Stock to the
          extent that the aggregate cash dividend per share of Common Stock
          in any quarter does not exceed the greater of (x) the amount per
          share of Common Stock of the next preceding quarterly dividend on
          the Common Stock to the extent that such preceding quarterly
          dividend did not require an adjustment of the exchange rate
          pursuant to this clause (v) (as adjusted to reflect subdivisions
          or combinations of the Common Stock), and (y) 3.75 percent of the
          average of the last reported sales price of the Common Stock
          during the ten trading days immediately prior to the date for
          declaration of such dividend, and excluding any dividend or
          distribution in connection with the liquidation, dissolution or
          winding up of ICG; (vi) payment in respect of a tender or
          exchange offer by ICG or any subsidiary of ICG for the Common
          Stock to the extent that the cash and value of any other
          consideration included in such payment per share of Common Stock
          exceeds the Average Market Value per share of Common Stock on the
          Trading Day next succeeding the last date on which tenders or
          exchanges may be made pursuant to such tender or exchange offer;
          and (vii) payment in respect of a tender offer or exchange offer
          by a person other than ICG or any subsidiary of ICG in which, as
          of the closing date of the offer, the Board of Directors is not
          recommending rejection of the offer. If any adjustment is
          required to be made as set forth in clause (v) above as a result
          of a distribution that is a quarterly dividend, such adjustment
          would be based upon the amount by which such distribution exceeds
          the amount of the quarterly cash dividend permitted to be
          excluded pursuant to such clause (v). If an adjustment is
          required to be made as set forth in clause (v) above as a result
          of a distribution that is not a quarterly dividend, such
          adjustment would be based upon the full amount of the
          distribution. The adjustment referred to in clause (vii) above
          will only be made if the tender offer or exchange offer is for an
          amount which causes that person's ownership of Common Stock to
          exceed 25% of the total shares of Common Stock outstanding and,
          if the cash and value of any other consideration included in such
          payment per share of Common Stock, exceeds the Average Market
          Value per share of Common Stock on the business day next
          succeeding the last date on which tenders or exchanges may be
          made pursuant to such tender or exchange offer. The adjustment
          referred to in clause (vii) above will not be made, however, if,
          as of the closing of the offer, the offering documents with
          respect to such offer disclose a plan or an intention to cause
          ICG to engage in a consolidation or merger of ICG or a sale of
          all or substantially all of ICG's assets. Notwithstanding the
          foregoing, no adjustment will be required as a result of (a) the
          issuance of shares of Common Stock as a result of any of the
          following (i) the grant or exercise of employee or director stock
          options, (ii) the exercise of outstanding warrants or conversion
          or exchange of existing notes and securities (including exchange
          of Class A Common Shares of Holdings--Canada), (iii) a
          contribution to ICG's 401(k) plan or ICG's 401(k) Wrap Around
          Deferred Compensation Plan and (iv) in satisfaction of ICG's
          obligations under its Employee Stock Purchase Plan or (b) the
          issuance of Common Stock as a dividend on or upon exchange of the
          Preferred Securities. Common Stock issued in connection with
          acquisitions of businesses or assets from persons that are not
          Affiliates of ICG will be deemed to have been issued for a price
          at least equal to Average Market Value.

               The Certificate of Designation, Rights and Preferences with
          respect to the ICG Preferred Stock (the "Certificate of
          Designation") provides that if ICG implements a stockholders'
          rights plan, such rights plan must provide that upon exchange of
          the Preferred Securities into Common Stock the holders will
          receive, in addition to the Common Stock issuable upon such
          exchange, such rights whether or not such rights have separated
          from the Common Stock at the time of such exchange.

               No adjustment in the exchange rate will be required unless
          such adjustment would require a change of at least one percent in
          the exchange rate then in effect; provided that any adjustment
          that would otherwise be required to be made shall be carried
          forward and taken into account in any subsequent adjustment. ICG
          reserves the right to make such increase in the exchange rate in

                                      28
     <PAGE>

          addition to those required in the foregoing provisions as ICG in
          its discretion shall determine to be advisable in order that
          certain stock-related distributions hereafter made by ICG to its
          stockholders shall not be taxable. Except as stated above, the
          exchange rate will not be adjusted for the issuance of Common
          Stock or any securities convertible into or exchangeable for
          Common Stock or carrying the right to purchase any of the
          foregoing.

               In the case of (i) any reclassification of the Common Stock
          (other than changes in par value or resulting from a subdivision
          or combination) or (ii) a consolidation or merger involving ICG
          or a sale or conveyance to another corporation of the property
          and assets of ICG as an entirety or substantially as an entirety,
          in each case as a result of which holders of Common Stock shall
          be entitled to receive stock, securities, other property or
          assets (including cash) with respect to or in exchange for such
          Common Stock, the holders of the Preferred Securities then
          outstanding will be entitled thereafter to exchange such
          Preferred Securities into the kind and amount of shares of stock,
          other securities or other property or assets which they would
          have owned or been entitled to receive upon such
          reclassification, consolidation, merger, sale or conveyance had
          such Preferred Securities been exchanged immediately prior to
          such reclassification, consolidation, merger, sale or conveyance,
          assuming that a holder of Preferred Securities would not have
          exercised any rights of election as to the stock, other
          securities or other property or assets receivable in connection
          therewith.

               In the event of a taxable distribution to holders of Common
          Stock or in certain other circumstances requiring an adjustment
          to the exchange rate, the holders of Preferred Securities may, in
          certain circumstances, be deemed to have received a distribution
          subject to United States income tax as a dividend.

               ICG from time to time may, to the extent permitted by law,
          increase the exchange rate (thus increasing the number of shares
          of Common Stock that would be issued in exchange for each
          Preferred Security) by any amount for any period of at least 20
          days, in which case ICG shall give at least 15 days' notice of
          such if ICG's Board of Directors has made a determination that
          such increase would be in the best interests of ICG, which
          determination shall be conclusive. ICG may, at its option, make
          such increases in the exchange rate, in addition to those set
          forth above, as the Board of Directors deems advisable to avoid
          or diminish any income tax to holders of Common Stock resulting
          from any dividend or distribution of stock (or rights to acquire
          stock) or from any event treated as such for income tax purposes.
          ICG does not intend to reduce the exchange price to an amount
          below the fair market value of the Common Stock.


          MANDATORY REDEMPTION BY FUNDING

               Unless earlier redeemed or exchanged, the Preferred
          Securities must be redeemed, out of funds legally available
          therefor, by Funding at a redemption price of 100% of the
          liquidation preference of the Preferred Securities plus accrued
          and unpaid dividends, if any, on the Mandatory Redemption Date.


          PROVISIONAL REDEMPTION BY FUNDING 

               The Preferred Securities are subject to redemption by
          Funding, in whole or in part, at any time after a date no more
          than six months after the Original Closing Date (the "Funding
          Date"), and on or prior to November 15, 2000, at a redemption
          price of 103% of the liquidation preference of the Preferred
          Securities to be redeemed plus accrued and unpaid dividends, if
          any, to the date of redemption, in the event that the Current
          Market Value of the Common Stock equals or exceeds the following
          Trigger Percentages of the exchange price then in effect for at
          least 20 trading days in any consecutive 30-day trading period
          ending on the trading day prior to the date of mailing of the
          notice of Provisional Redemption, if called for redemption in the
          12-month period ending on November 15 of the indicated year:

                    YEAR                TRIGGER PERCENTAGES
                    ----                -------------------
                    1998                        170%
                    1999                        160
                    2000                        150

                                      29
     <PAGE>

               Upon any Provisional Redemption, Funding will make a
          Dividend Make-Whole Payment with respect to the Preferred
          Securities called for redemption in an amount equal to the pro
          rata portion of the liquidation proceeds of any remaining
          Treasury Strips held by Funding. Funding will be obligated to
          make the Dividend Make-Whole Payment on all Preferred Securities
          called for Provisional Redemption, regardless of whether such
          Preferred Security is exchanged prior to the Provisional
          Redemption Date. The Dividend Make-Whole Payment must be paid in
          cash.


          OPTIONAL REDEMPTION BY FUNDING

               The Preferred Securities are also subject to optional
          redemption by Funding on or after November 18, 2000 (the "Initial
          Redemption Date"). At any time and from time to time on or after
          the Initial Redemption Date and until the Mandatory Redemption
          Date, Funding will have the right to redeem, in whole or in part,
          the Preferred Securities at a redemption price equal to the
          percentage of the liquidation preference set forth below,
          together with accrued and unpaid dividends, if any, to the
          Optional Redemption Date, if redeemed in the 12-month period
          beginning on November 15 of the indicated year:

                    YEAR                REDEMPTION PRICE
                    ----                ----------------
                    2000                       102%
                    2001                       101
                    2002 and thereafter        100


          METHOD OF PAYMENT OF REDEMPTION PRICE

               The redemption price pursuant to a Provisional Redemption,
          an Optional Redemption or the Mandatory Redemption may be paid,
          in each case at Funding's option, in (i) cash, (ii) Common Stock,
          based upon 90% of the Average Market Value of the Common Stock in
          the case of the Provisional Redemption or the Optional Redemption
          and 100% of the Average Market Value of the Common Stock in the
          case of the Mandatory Redemption, or (iii) any combination of
          cash or Common Stock; provided that Funding, in its notice of
          such redemption, must state whether the redemption price will be
          paid in cash, Common Stock or both, and provided that any payment
          must be made in cash to the extent ICG shall have provided
          Funding with cash (whether through dividends on the ICG Preferred
          Stock or otherwise) to make all or any portion of such payment
          with respect to such redemption.


          FUNDAMENTAL CHANGE EXCHANGE RATE ADJUSTMENT

               If ICG or Funding makes an announcement of the occurrence or
          an imminent occurrence of a Fundamental Change (as defined below)
          at any time prior to the Mandatory Redemption Date, there will be
          an adjustment to the exchange rate of the Preferred Securities
          (the "Fundamental Change Exchange Rate") such that such exchange
          rate will thereafter equal the liquidation preference of the
          Preferred Securities, divided by the Fundamental Change Average
          Market Price (as defined below), unless the Fundamental Change
          Exchange Rate is lower than the then current exchange rate of the
          Preferred Securities as calculated in the manner described in
          "--Exchange Rights" (in which case there will be no such
          adjustment to the exchange rate).

               The term "Fundamental Change" means the occurrence of any
          transaction or event in connection with which all or
          substantially all of the outstanding Common Stock shall be
          exchanged for, converted into, acquired for or constitute the
          right to receive stock, securities, other property or assets
          (including cash) of another entity or person (whether by means of
          an exchange offer, liquidation, tender offer, consolidation,
          merger, combination, reclassification, recapitalization or
          otherwise). "Fundamental Change Average Market Price" of the
          Common Stock means the arithmetic average of the Current Market
          Value for the ten trading days ending on the fifth business day
          prior to the date of the closing of the Fundamental Change.

          LIQUIDATION DISTRIBUTION UPON DISSOLUTION 

               In the event of any voluntary or involuntary liquidation,
          dissolution, winding-up or termination of Funding (each a
          "Liquidation"), the then holders of the Preferred Securities will
          be entitled to receive out of the assets of Funding (which will
          include the ICG Preferred Stock, any interest on and principal of
          the Treasury Strips that are held in the Escrow Account, any
          Common Stock that Funding received from ICG as a dividend (or
          otherwise) and has not distributed as a dividend on the Preferred
          Securities or sold in the open market, and any other assets of
          Funding), after satisfaction of liabilities to creditors, if any,
          distributions in an amount equal to the aggregate of the stated
          liquidation preference of $50 of Preferred Security plus accrued
          and unpaid dividends thereon to the date of payment (the
          "Liquidation Distribution").

               If, upon any such Liquidation, the Liquidation Distribution
          can be paid only in part because Funding has insufficient assets
          available to pay in full the aggregate Liquidation Distribution,
          then the amounts payable by Funding on the Preferred Securities
          shall be paid on a pro rata basis. ICG will be obligated to pay
          dividends, consisting of ICG Preferred Stock, to Funding so that
          it will be able to make the Liquidation Distribution in full.


          VOTING RIGHTS

               The holders of Preferred Securities have no voting rights,
          except as otherwise required by law and except as set forth
          below. The Operating Agreement provides that Funding may not
          amend the Operating Agreement so as to affect adversely the
          specific rights, preferences, privileges or voting rights of
          holders of Preferred Securities, cause the dissolution, winding-
          up or termination of Funding, issue any additional securities or
          increase the authorized number of Preferred Securities, without
          the affirmative vote or consent of the holders of at least a
          majority of the outstanding Preferred Securities, voting or
          consenting, as the case may be, separately as one class.
          Furthermore, the Certificate of Designation provides that ICG may
          not, without the approval of the holders of a majority of the ICG
          Preferred Stock, amend the Certificate of Incorporation of ICG so
          as to have a material adverse effect on the specific rights,
          preferences, privileges or voting rights of the holders of the
          ICG Preferred Stock with respect to the ICG Preferred Stock, or
          cause the dissolution, winding-up or termination of Funding.
          Funding will initially be the sole holder of the ICG Preferred
          Stock. Funding has agreed not to grant such approval without the
          consent of the holders of a majority of the Preferred Securities
          then outstanding.


          THE GUARANTEE; LACK OF PRACTICAL BENEFIT TO HOLDERS FROM THE
          GUARANTEE

               Set forth below is a summary of information concerning the
          guarantee of the Preferred Securities (the "Guarantee") by ICG
          for the benefit of the holders of Preferred Securities. The
          summary does not purport to be complete and is subject in all
          respects to the respective provisions of, and is qualified in its
          entirety by reference to, the Guarantee Agreement between ICG and
          Funding, a copy of which is available from ICG upon request.

               General. Pursuant to and to the extent set forth in the
          Guarantee, ICG has agreed to pay in full to the holders of the
          Preferred Securities (except to the extent paid by Funding), as
          and when due, regardless of any defense, right of set off or
          counterclaim which Funding may have or assert, the following
          payments (the "Guarantee Payments"), without duplication: (i) any
          accrued and unpaid distributions that are required to be paid on
          the Preferred Securities, to the extent Funding has funds
          available therefor, (ii) the redemption price, with respect to
          any Preferred Securities called for redemption by Funding, to the
          extent Funding has funds available therefor and (iii) upon a
          voluntary or involuntary dissolution, winding-up or termination
          of Funding, the lesser of (a) the aggregate of the liquidation
          preference and all accrued and unpaid dividends on the Preferred
          Securities to the date of payment to the extent Funding has funds
          available therefor and (b) the amount of assets of Funding
          remaining available for distribution to holders of Preferred
          Securities upon the liquidation of Funding. The Guarantee is also
          subject to the contractual restrictions contained in the
          Indentures. The Indentures effectively prohibit any cash payment
          on the Guarantee.

               Because the Guarantee is limited by the amount of the funds
          held by Funding and is limited by the provision of the
          Indentures, the Guarantee is of no practical benefit to holders
          of the Preferred Securities.

     <PAGE>

               Amendments and Assignment. Except with respect to any
          changes that do not materially adversely affect the rights of
          holders of Preferred Securities (in which case no vote will be
          required), the Guarantee may be amended only with the prior
          approval of the holders of at least a majority in liquidation
          preference of all the outstanding Preferred Securities. All
          guarantees and agreements contained in the Guarantee shall bind
          the successors, assigns, receivers, trustees and representatives
          of ICG and shall inure to the benefit of the holders of the
          Preferred Securities then outstanding. Except in connection with
          any permitted merger or consolidation of ICG with or into another
          entity or any permitted sale, transfer or lease of ICG's assets
          to another entity, ICG may not assign its rights or delegate its
          obligations under the Guarantee without the prior approval of the
          holders of at least a majority in liquidation preference of the
          Preferred Securities then outstanding.

               Termination of the Guarantee. The Guarantee will terminate
          as to each holder of the Preferred Securities upon (i) full
          payment of the redemption price of all Preferred Securities, (ii)
          distribution to the holders of the Preferred Securities of all of
          the assets of Funding, including the ICG Preferred Stock, any
          interest on and principal of the Treasury Strips that are held in
          the Escrow Account and any Common Stock that Funding received
          from ICG as dividend (or otherwise) and has not distributed as
          dividend on the Preferred Securities or sold in the open market
          or (iii) the exchange of all of such holder's Preferred
          Securities into Common Stock.

               Status of the Guarantee; Subordination. The Guarantee
          constitutes an unsecured obligation of ICG and ranks subordinate
          and junior to all other liabilities of ICG and senior to the
          Common Stock.

               Because the Guarantee is limited by the amount of the funds
          in Funding, if ICG were to default on its obligation to pay
          amounts payable on the ICG Preferred Stock, Funding would lack
          available funds for the payment of dividends or amounts payable
          on redemption of the Preferred Securities or otherwise, and, in
          such event, holders of the Preferred Securities would not be able
          to rely upon the Guarantee for payment of such amounts. Instead,
          holders of the Preferred Securities would rely upon the
          enforcement of Funding's rights as registered holder of the ICG
          Preferred Stock against ICG pursuant to the terms of the ICG
          Preferred Stock.


          PREFERRED SECURITIES BOOK ENTRY; DELIVERY AND FORM

               The certificates representing the Preferred Securities were
          issued in fully registered form. Preferred Securities sold in
          reliance on Rule 144A are represented by a single, permanent
          global Preferred Securities certificate, in definitive, fully
          registered form (the "Restricted Global Preferred Securities
          Certificate") and are deposited with a custodian for DTC and
          registered in the name of a nominee of DTC. The Restricted Global
          Preferred Securities Certificate is subject to certain
          restrictions on transfer set forth therein and bears the legend
          regarding such restrictions set forth under "Transfer
          Restrictions." Owners of beneficial interests in Restricted
          Global Preferred Securities Certificate will generally not be
          entitled to receive physical delivery of a physical certificate
          for their Preferred Securities ("Certificated Preferred
          Securities"). The Preferred Securities are not issuable in bearer
          form.

               Upon the issuance of the Restricted Global Preferred
          Securities Certificate, DTC or its custodian credited, on its
          internal system, the respective liquidation preference of the
          individual beneficial interests represented by Restricted Global
          Preferred Securities Certificate, to the accounts of persons who
          have accounts with such depositary. Such accounts initially are
          designated by or on behalf of Morgan Stanley & Co. Incorporated
          ("Morgan Stanley") and Deutsche Morgan Grenfell Inc. ("DMG," and
          together with Morgan Stanley, the "Initial Purchasers").
          Ownership of beneficial interests in the Restricted Global
          Preferred Securities Certificate are limited to persons who have
          accounts with DTC ("participants") or persons who hold interests
          through participants. Ownership of beneficial interests in the
          Restricted Global Preferred Securities Certificate is shown on,
          and the transferor of that ownership is effected only through,
          records maintained by DTC or its nominee (with respect to
          interests of participants) and the records of participants (with
          respect to interests of persons other than participants).
          "Qualified institutional buyers," as defined in Rule 144A under
          the Securities Act, may hold their interests in the Restricted
          Global Preferred Securities Certificate directly through DTC if
          they are participants in such system, or indirectly through
          organizations that are participants in such system.

                                      32
     <PAGE>

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

               Payments made with respect to the Restricted Global
          Preferred Securities Certificate will be made to DTC or its
          nominee, as the case may be, as the registered owner thereof.
          Neither Funding, ICG nor the Initial Purchasers will have any
          responsibility or liability for any aspect of the records
          relating to or payments made on account of beneficial ownership
          interests in the Restricted Global Preferred Securities
          Certificate or for maintaining, supervising or reviewing any
          records relating to such beneficial ownership interests.

               Funding and ICG expect that DTC or its nominee, upon receipt
          of any payments made with respect to the Restricted Global
          Preferred Securities Certificate, will credit participants'
          accounts with payments in amounts proportionate to their
          respective beneficial interests in the amount of the Restricted
          Global Preferred Securities Certificate as shown on the records
          of DTC or its nominee. Funding and ICG also expect that payments
          by 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.

               Funding and ICG understand that DTC will take any action
          permitted to be taken by a holder of Preferred Securities only at
          the direction of one or more participants to whose account the
          DTC interests in the Restricted Global Preferred Securities
          Certificate are credited and only in respect of such portion of
          the aggregate liquidation preference of Preferred Securities as
          to which such participant or participants has or have given such
          direction.

               Funding and ICG understand: 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 transaction 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 interest in the Restricted
          Global Preferred Securities Certificate 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 ICG, Funding nor the Initial Purchasers will have
          any responsibility for the performance by DTC or its respective
          participants or indirect participants of its respective
          obligations under the rules and procedures governing their
          operations.


          MERGER, CONSOLIDATION OR SALE OF ASSETS OF FUNDING

               Funding may not consolidate with, merge with or into, or be
          replaced by, or convey, transfer or lease its properties and
          assets as an entirety or substantially as an entirety to, any
          entity, except as described below. Funding may, in order to avoid
          federal income tax or Investment Company Act of 1940 (the "1940
          Act") considerations adverse to ICG or Funding or the holders of
          the Preferred Securities, without the consent of the holders of
          the Preferred Securities, consolidate with, merge with or into,
          or be replaced by a limited partnership or trust organized as
          such under the laws of any state of the United States of America,
          provided that (i) such successor entity either (x) expressly

                                      33
     <PAGE>

          assumes all of the obligations of Funding under the Preferred
          Securities or (y) substitutes for the Preferred Securities other
          securities having substantially the same terms as the Preferred
          Securities (the "Successor Securities") so long as the Successor
          Securities rank, with respect to participation in the profits or
          assets of the successor entity, at least as high as the Preferred
          Securities rank with respect to payment of dividends and
          distribution of assets upon the liquidation, dissolution or
          winding-up of Funding, (ii) ICG expressly acknowledges such
          successor entity as the holder of the ICG Preferred Stock and its
          obligations under the Guarantee with respect to the Successor
          Securities, (iii) such merger, consolidation or replacement does
          not cause the Preferred Securities (or any Successor Securities)
          to be delisted by any national securities exchange or other
          organization on which the Preferred Securities are then listed,
          (iv) such merger, consolidation or replacement does not cause the
          Preferred Securities (or any Successor Securities) to be
          downgraded by any nationally recognized statistical rating
          organization, (v) such merger, consolidation or replacement does
          not adversely affect the powers, preferences and other special
          rights of the holders of the Preferred Securities (or any
          Successor Securities) in any material respect (other than with
          respect to any dilution of the holders' interest in the new
          entity), and (vi) prior to such merger, consolidation or
          replacement, ICG has received an opinion of nationally recognized
          independent counsel to Funding experienced in such matters to the
          effect that (x) such successor entity will be treated as a
          partnership or as a trust, as appropriate, for federal income tax
          purposes, (y) following such merger, consolidation or
          replacement, ICG and such successor entity will be in compliance
          with the 1940 Act without registering thereunder as an investment
          company and (z) such merger, consolidation or replacement will
          not adversely affect the limited liability of the holders of the
          Preferred Securities or Successor Securities.


          MISCELLANEOUS

               The manager of Funding is authorized and directed to conduct
          its affairs and to operate in such a way that Funding will not be
          deemed to be an "investment company" required to be registered
          under the 1940 Act or taxed as a corporation for federal income
          tax purposes. In this connection, the manager of Funding is
          authorized to take any action not inconsistent with applicable
          law or the Operating Agreement that does not adversely affect the
          interests of the holders of the Preferred Securities and that the
          manager of Funding determines in its discretion to be necessary
          or desirable for such purposes.

                          DESCRIPTION OF ICG PREFERRED STOCK

               General. ICG is authorized to issue 1,000,000 shares of
          preferred stock, $.01 par value per share. On the date of this
          Prospectus, no shares of preferred stock are outstanding. The
          board of directors of ICG has authorized the issuance of up to
          50,000 shares of a series of exchangeable preferred stock (the
          "Exchangeable Preferred Stock") and ICG has filed a Certificate
          of Designation with the Secretary of State of Delaware as
          required by Delaware law reflecting the authorization of such
          series of preferred stock. The Exchangeable Preferred Stock will
          be issued by ICG on or before February 15, 1998 and, when so
          issued and paid for by Funding, will be fully paid and
          nonassessable, and the holders thereof will not have any
          subscription or preemptive rights related thereto. The
          Exchangeable Preferred Stock will be issued without coupons, in
          denominations of $10,000 liquidation preference and any integral
          multiple thereof. Each share of Exchangeable Preferred Stock will
          have a liquidation preference at maturity of $10,000.

               Ranking. The Exchangeable Preferred Stock will rank, with
          respect to dividend distributions and distributions upon the
          liquidation, winding-up and dissolution of ICG, (i) senior to all
          classes of common stock of ICG and to each other class of capital
          stock or series of preferred stock established after
          September 24, 1997 by ICG's board of directors, the terms of
          which do not expressly provide that it ranks senior to or on a
          parity with the Exchangeable Preferred Stock as to dividend
          distributions and distributions upon the liquidation, winding-up
          and dissolution of ICG (collectively referred to with the common
          stock of ICG as "ICG Junior Securities"); (ii) on a parity with
          any class of capital stock or series of preferred stock issued by
          ICG established after September 24, 1997 by ICG's board of
          directors, the terms of which expressly provide that such class
          or series will rank on a parity with the Exchangeable Preferred
          Stock as to dividend distributions and distributions upon the
          liquidation, winding-up and dissolution of ICG (collectively
          referred to as "ICG Parity Securities") and (iii) junior to each
          class of capital stock or series of preferred stock issued by ICG
          established after September 24, 1997 by ICG's board of directors,
          the terms of which expressly provide that such class or series
          will rank senior to the Exchangeable Preferred Stock as to
          dividend distributions and distributions upon liquidation,
          winding-up and dissolution of ICG (collectively referred to as
          "ICG Senior Securities"). The Exchangeable Preferred Stock will
          be subject to the issuance of series of ICG Junior Securities,
          ICG Parity Securities and ICG Senior Securities; provided that
          ICG may not issue any new class of ICG Senior Securities without
          the approval of the holders of at least a majority of the shares
          of Exchangeable Preferred Stock then outstanding, voting or
          consenting, as the case may be, separately as one class.

               Dividends. Dividends on the Exchangeable Preferred Stock
          will be payable quarterly. Until November 15, 2000, the dividends
          will be payable in additional shares of Exchangeable Preferred
          Stock. From November 15, 2000, the dividends will be payable in
          shares of Common Stock (or in cash or any combination of cash and
          Common Stock) such that the number of shares of Common Stock
          (plus any cash) paid as dividends will (i) enable Funding to
          transfer such shares to the holders of the Preferred Securities
          in payment of dividends on the Preferred Securities or (ii) be
          sufficient, when sold in the open market by Funding, for Funding
          to make its dividend payments on the Preferred Securities on the
          relevant Dividend Payment Date, which is February 15, May 15,
          August 15 and November 15 of each year (each, a "Dividend Payment
          Date"). However, the indentures for ICG's outstanding high yield
          notes (the "Indentures") effectively prohibit the payment of cash
          dividends by ICG, and future agreements may provide for
          restrictions on the payment of cash dividends.

               Voting Rights. The holders of shares of Exchangeable
          Preferred Stock will have no voting rights, except as otherwise
          required by law and except as set forth below. The Certificate of
          Designation governing the Exchangeable Preferred Stock provides
          that ICG may not, without the approval of the holders of a
          majority of the Exchangeable Preferred Stock, amend the
          Certificate of Designation or the Certificate of Incorporation of
          ICG so as to have a material adverse effect on the specific
          rights, preferences, privileges or voting rights of holders of
          shares of Exchangeable Preferred Stock, or cause the dissolution,
          winding-up or termination of Funding. Funding is expected to be
          the sole holder of the Exchangeable Preferred Stock. Funding will
          not grant such approval without the consent of the holders of a
          majority of the shares of the Preferred Securities then
          outstanding.

               Exchange of the Exchangeable Preferred Stock. The
          Exchangeable Preferred Stock will be exchangeable into Common
          Stock at the option of Funding (upon request by a holder of the
          Preferred Securities) at any time prior to the business day

                                      35
     <PAGE>

          immediately preceding the date of repayment of such Exchangeable
          Preferred Stock at an initial exchange rate of 416.22 shares of
          Common Stock for each Exchangeable Preferred Stock, subject to
          certain adjustments.

               Liquidation Preference. Upon any voluntary or involuntary
          liquidation, dissolution or winding-up of ICG, holders of
          Exchangeable Preferred Stock will be entitled to be paid, out of
          the assets of ICG available for distribution, $10,000 per share
          of Exchangeable Preferred Stock, plus an amount in cash equal to
          accumulated and unpaid dividends thereon to the date fixed for
          liquidation, dissolution or winding-up (including an amount equal
          to a prorated dividend for the period from the last dividend
          payment date to the date fixed for liquidation, dissolution or
          winding-up), before any distribution is made on any ICG Junior
          Securities, including, without limitation, Common Stock. If, upon
          any voluntary or involuntary liquidation, dissolution or winding-
          up of ICG, the amounts payable with respect to the Exchangeable
          Preferred Stock and all other ICG Parity Securities are not paid
          in full, the holders of the Exchangeable Preferred Stock and the
          ICG Parity Securities will share equally and ratably in any
          distribution of assets of ICG with respect to the Exchangeable
          Preferred Stock and ICG Parity Securities, in proportion to the
          full liquidation preference and accumulated and unpaid dividends
          to which is entitled. After payment of the full amount of the
          liquidation preferences and accumulated and unpaid dividends to
          which they are entitled, the holders of shares of Exchangeable
          Preferred Stock will not be entitled to any further participation
          in any distribution of assets of ICG.

               Mandatory Redemption by ICG. The Exchangeable Preferred
          Stock must be redeemed by ICG at a redemption price of 100% of
          the liquidation preference of the Exchangeable Preferred Stock
          plus accrued and unpaid dividends, if any, two business days
          prior to November 15, 2009, which is the Mandatory Redemption
          Date for the Exchangeable Preferred Stock.

          SELLING STOCKHOLDER

               The Selling Stockholder of the Common Stock is Funding, a
          Delaware limited liability company. ICG owns all of the common
          limited liability company securities of Funding, and ICG is the
          manager of Funding. Funding is offering up to an aggregate of
          200,000 shares of Common Stock, all of which may be offered
          pursuant to this Prospectus.

               The Selling Preferred Securityholders and the Selling
          Stockholder may be referred to herein individually and
          collectively, as the case may be, as the "Selling Holders."
          Except as set forth above and in the following sentence, none of
          the Selling Holders has, or within the past three years has had,
          any position, office or other material relationship with Funding
          or ICG or any of their predecessors or affiliates. From time to
          time, certain broker-dealers and their affiliates in the ordinary
          course of business may have acquired or disposed of, or may in
          the future acquire or dispose of, certain securities of ICG and
          Funding or their affiliates, for their own accounts or for the
          accounts of others. Because the Selling Holders may, pursuant to
          this Prospectus, offer all or some portion of the Preferred
          Securities, the ICG Preferred Stock or the Common Stock issuable
          upon exchange of the Preferred Securities, no estimate can be
          given as to the amount of the Preferred Securities, the ICG
          Preferred Stock or the Common Stock issuable upon exchange of
          Preferred Securities that will be held by the Selling Holders
          upon termination of any such sales. In addition, the Selling
          Holders identified above may have sold, transferred or otherwise
          disposed of all or a portion of their Preferred Securities since
          the date on which they provided the information regarding their
          Preferred Securities included herein in transactions exempt from
          the registration requirements of the Securities Act. See "Plan of
          Distribution."

               CERTAIN UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

               The following summary describes the material anticipated
          United States federal income tax consequences of the purchase,
          ownership and disposition of the Preferred Securities. Except
          where noted, it deals only with Preferred Securities held as
          capital assets by United States Holders and does not deal with
          special situations, such as those of dealers in securities or
          currencies, financial institutions, life insurance companies,
          foreign corporations, persons who are not citizens or residents
          of the United States or persons who hold Preferred Securities as
          a part of a hedging or conversion transaction or a straddle. In
          addition, the following discussion does not address the tax
          consequences of the laws of any state, locality or foreign
          jurisdiction. Furthermore, the discussion below is based upon the
          provisions of the Internal Revenue Code of 1986, as amended (the
          "Code"), and regulations, rulings and judicial decisions
          thereunder as of the date hereof, and such authorities may be
          repealed, revoked or modified so as to result in federal income
          tax consequences different from those discussed below. In
          addition, the discussion below includes certain matters as to
          which ICG has made determinations which it believes are accurate.
          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
          PREFERRED SECURITIES.

               As used herein, a "United States Holder" means a beneficial
          owner of Preferred Securities 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 United States fiduciaries have the
          authority to control all substantial decisions. A foreign
          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). 


          PARTNERSHIP STATUS OF FUNDING

               A partnership is not a taxable entity and incurs no federal
          income tax liability. Instead, each partner is required to take
          into account its allocable share of items of income, gain, loss
          and deduction of the partnership in computing the partner's
          federal income tax liability, regardless of whether cash
          distributions are made. Distributions by a partnership to a
          partner are generally not taxable unless the amount of any cash
          distributed is in excess of the partner's adjusted tax basis in
          its partnership interest.

               No ruling has been or will be sought from the IRS as to the
          status of Funding as a partnership for federal income tax
          purposes. Instead Funding has relied on the opinion of Reid &
          Priest LLP that it will be classified as a partnership for United
          States federal income tax purposes. Such opinion is based upon
          the Code, the regulations thereunder, published revenue rulings
          and court decisions and upon Funding's representations that (i)
          it will not earn income other than from the ICG Preferred Stock
          and from the Treasury Strips and (ii) it will not elect to be
          treated as a corporation.


          TAX CONSEQUENCES TO UNITED STATES HOLDERS 

               Flow-through of Taxable Income 

               No federal income tax will be paid by Funding. Instead, each
          Preferred Securityholder will be required to report on its income
          tax return its allocable share of the income, gains, losses and
          deductions of Funding without regard to whether corresponding
          cash distributions are received by such Preferred Securityholder.
          Consequently, a Preferred Securityholder may be allocated income
          from Funding even if such Preferred Securityholder has not

                                      39
     <PAGE>

          received a cash distribution. Each Preferred Securityholder will
          be required to include in income its allocable share of income,
          gains, losses and deduction of Funding for the taxable year of
          Funding ending with or within the taxable year of the Preferred
          Securityholder. The taxable income of Funding will generally be
          dividend income from, and capital gains recognized with respect
          to, the ICG Preferred Stock and interest income on, and capital
          gain recognized with respect to, the Treasury Strips.

               The Preferred Securityholders will first be allocated income
          and gain of Funding in an amount so that all cumulative
          allocations of taxable income and gain equals all cumulative
          dividend distributions to the Preferred Securityholders. Any
          remaining taxable income and gain generally will then be
          allocated to ICG (except for deemed dividends resulting from the
          optional redemption or because of the adjustment in the exchange
          rate, which dividends will generally be allocated to the
          Preferred Securityholders). These allocation provisions are
          designed to reconcile tax allocations to economic allocations.
          However, these allocations do not comply with the technical
          requirements set forth in the Treasury regulations. Consequently,
          no assurance can be given that the IRS will not challenge these
          allocations. If theses allocations are successfully challenged by
          the IRS, the amount of taxable income or loss allocated to
          Preferred Securityholders for federal income tax purposes may be
          increased and/or reduced or the character of such income may be
          modified.

               Funding does not presently intend to make an election under
          Section 754 of the Code. As a result, a purchaser of Preferred
          Securities will not be permitted to adjust its taxable income
          from Funding to reflect any difference between its purchase price
          for the Preferred Securities and Funding's underlying tax basis
          for its assets.

               Treatment of Distributions by Funding

               Distributions by Funding to a Preferred Securityholder
          generally will not be taxable to the Preferred Securityholder for
          federal income tax purposes to the extent of such Preferred
          Securityholder's tax basis in its Preferred Securities
          immediately before the distribution. Cash distributions in excess
          of a Preferred Securityholder's tax basis in its Preferred
          Securities generally will be considered to be gain from the sale
          or exchange of the Preferred Securities, taxable in accordance
          with the rules described under "--Disposition of Preferred
          Securities" below. To the extent Funding distributes Common Stock
          other than in liquidation of such Preferred Securities, the
          Preferred Securityholder will recognize no gain or loss and will
          have a tax basis in such stock equal to the lesser of (i) tax
          basis of such stock in the hands of Funding or (ii) such
          Preferred Securityholder's tax basis in its Preferred Securities
          reduced by the amount of any cash distributed in the non-
          liquidating distribution. If the Common Stock distribution is in
          liquidation of such Preferred Securities, the Preferred
          Securityholder will recognize no gain or loss and will have a tax
          basis in the Common Stock received equal to its tax basis in its
          Preferred Securities reduced by the amount of any cash
          distributed in liquidation of its Preferred Securities.

               Tax Basis of Preferred Securities

               A Preferred Securityholder's initial tax basis for its
          Preferred Securities will be the amount it paid for the Preferred
          Securities. That basis generally will be increased by its share
          of Funding's income and generally will be decreased (but not
          below zero) by distributions from Funding and by the Preferred
          Securityholder's share of Funding's losses, if any. Non-
          liquidating distributions of Common Stock by Funding will reduce
          the Preferred Securityholder's tax basis in the Preferred
          Securities (but not below zero) by the amount of Funding's tax
          basis in such distributed stock. In addition, pursuant to Section
          1059 of the Code, a Preferred Securityholder's tax basis in its
          Preferred Securities may be reduced by its share of any
          "extraordinary" dividends received by Funding. See "--Dividends
          on the ICG Preferred Stock" below. 

               Interest on Treasury Strips

               Funding will purchase interest portions of stripped United
          States Treasury Obligations which are treated as bonds that were
          originally issued at a discount ("original issue discount").
          Original issue discount represents interest for federal income
          tax purposes and can generally be defined as the difference
          between the price at which a bond was issued and its stated
          redemption price at maturity. For purposes of the preceding
          sentence, stripped obligations, such as the Treasury Strips,

                                      40
     <PAGE>

          which consist of a right to receive interest, will be treated by
          Funding as originally issued on their purchase date at an issue
          price equal to their respective purchase prices thereof. Original
          issue discount on stripped Treasury Obligations (which were
          issued or treated as issued on or after July 2, 1982) is deemed
          earned based on a compounded, constant yield to maturity over the
          life of such obligation, taking into account the compounding of
          accrued interest at least annually, resulting in an increasing
          amount of original issue discount includible in income each year.
          If the stripped Treasury Obligation has a maturity of one year or
          less, the original issue discount may, in certain circumstances,
          be treated as interest income upon maturity or disposition rather
          than over the term of the obligation. Each Preferred
          Securityholder is required to include in income its allocable
          share of original issue discount which accrues each year.

               Dividends on the ICG Preferred Stock

               Distributions of cash or of additional ICG Preferred Stock
          or Common Stock on the ICG Preferred Stock will be treated as
          dividends to Funding (and, in turn, to the Preferred
          Securityholders) to the extent of ICG's current and accumulated
          earnings and profits as determined under United States federal
          income tax principles. The amount of ICG's earnings and profits
          at any time will depend upon the future actions and financial
          performance of ICG. The amount of a distribution of additional
          ICG Preferred Stock or Common Stock will equal the fair market
          value of the additional ICG Preferred Stock or Common Stock
          distribution on the date of the distribution.

               ICG believes that it does not presently have any current or
          accumulated earnings and profits. Consequently, unless ICG
          generates earnings and profits in the future, distributions with
          respect to the ICG Preferred Stock will exceed ICG's current and
          accumulated earnings and profits. Such distributions will be
          treated as a nontaxable return of capital and will be applied
          against and reduce (by the then fair market value of the
          distributed ICG Preferred Stock or Common Stock) the tax basis of
          the ICG Preferred Stock in the hands of Funding with respect to
          which such distributions are made (but not below zero), thus
          increasing the amount of any gain or reducing any loss which
          would otherwise be realized by Funding upon a redemption or other
          disposition of such ICG Preferred Stock. The amount of any such
          distribution which exceeds the tax basis of the ICG Preferred
          Stock in the hands of Funding will be treated as capital gain to
          Funding (and, in turn, to the Preferred Securityholders) and
          should be either long-term or short-term capital gain depending
          on Funding's holding period in the ICG Preferred Stock. The ICG
          Preferred Stock or Common Stock received by Funding as a dividend
          will have a tax basis to Funding equal to its fair market value
          on the date of distribution.

               Under Section 243 of the Code, corporate Preferred
          Securityholders generally will be able to deduct 70% of the
          amount of their pro-rata share of any dividends received by
          Funding. There are, however, many exceptions and restrictions
          relating to the availability of such dividends-received
          deduction. Section 246A of the Code reduces the dividends-
          received deduction allowed to a corporate stockholder that has
          incurred indebtedness "directly attributable" to its investment
          in portfolio stock. Section 246(c) of the Code requires that, in
          order to be eligible for the dividends-received deduction, a
          corporate stockholder must generally hold the share of stock for
          a 46-day minimum holding period or a 91-day period in certain
          circumstances. A taxpayer's holding period for these purposes is
          suspended during any period in which a stockholder has certain
          options or contractual obligations with respect to substantially
          identical stock or holds one or more other positions with respect
          to substantially identical stock that diminishes the risk of loss
          from holding the stock. The IRS may take the position that these
          restrictions relating to the availability of the dividends-
          received deduction apply to a Preferred Securityholder who
          indirectly owns the ICG Preferred Stock held by Funding by
          applying these restrictions based on the Preferred
          Securityholder's holding period in the Preferred Securities
          (rather than upon Funding's holding period in the ICG Preferred
          Stock).

               Under Section 1059 of the Code, a corporate stockholder is
          required to reduce its tax basis (but not below zero) in stock by
          the nontaxed portion of any "extraordinary dividend" if such
          stock has not been held for more than two years before the
          earliest of the date such dividend is declared, announced or
          agreed to. Generally, the nontaxed portion of an extraordinary
          dividend is the amount excluded from income by operation of the
          dividends-received deduction provisions of Section 243 of the
          Code. A dividend on the ICG Preferred Stock generally would be an
          extraordinary dividend if it (i) equals or exceeds 5% of the
          corporate stockholder's adjusted tax basis in the ICG Preferred

                                      41
     <PAGE>

          Stock, treating all dividends having ex-dividend dates within an
          85-day period as one dividend or (ii) exceeds 20% of the
          corporate stockholder's adjusted tax basis in such stock,
          treating all dividends having ex-dividend dates within a 365-day
          period as one dividend. In determining whether a dividend paid on
          preferred stock is an extraordinary dividend, a corporate
          stockholder may elect to substitute the fair market value of the
          preferred stock for such stockholder's tax basis for purposes of
          applying these tests, provided that such fair market value is
          established to the satisfaction of the Secretary of Treasury as
          of the day before the ex-dividend date. An extraordinary dividend
          also currently includes any amount treated as a dividend in the
          case of a redemption that is either non-pro-rata as to all
          stockholders or in partial liquidation of ICG, regardless of the
          stockholder's holding period and regardless of the size of the
          dividend. Section 1059, if applicable, is applied to Funding by
          treating each Preferred Securityholder as the owner of its share
          of the ICG Preferred Stock held by Funding and thereby having
          Funding adjust its tax basis in the ICG Preferred Stock and
          having each Preferred Securityholder make a corresponding
          adjustment to its tax basis in the Preferred Securities. If any
          part of the nontaxed portion of an extraordinary dividend is not
          applied to reduce the corporate Preferred Securityholder's tax
          basis as a result of the limitation on reducing such basis below
          zero, such part will be treated as gain at the time when the
          extraordinary dividend is paid.

               Special rules exist with respect to extraordinary dividends
          for "qualified preferred dividends." A qualified preferred
          dividend is any fixed dividend payable with respect to any share
          of stock which (i) provides for fixed preferred dividends payable
          not less frequently than annually and (ii) is not in arrears as
          to dividends at the time the United States Holder acquires such
          stock. A qualified preferred dividend does not include any
          dividend payable with respect to any share of stock if the actual
          rate of return on such stock exceeds 15%. Section 1059 does not
          apply to qualified preferred dividend if the corporate
          stockholder holds such stock for more than five years. If the
          stockholder disposes of such stock before it has been held for
          more than five years, the amount subject to extraordinary
          dividend treatment with respect to qualified preferred dividends
          is limited to the excess of the actual rate of return over the
          stated rate of return. Actual or stated rates of return are the
          actual or stated dividends expressed as a percentage of the
          lesser of (1) the stockholder's tax basis in such stock or (2)
          the liquidation preference of such stock. CORPORATE PREFERRED
          SECURITYHOLDERS ARE URGED TO CONSULT THEIR TAX ADVISORS WITH
          RESPECT TO THE POSSIBLE APPLICATION OF SECTION 1059 TO THEIR
          OWNERSHIP AND DISPOSITION OF THE PREFERRED SECURITIES.

               A corporate Preferred Securityholder's liability for
          alternative minimum tax may be affected by the portion of the
          dividends received which such corporate Preferred Securityholder
          deducts in computing taxable income. This results from the fact
          that corporate stockholders are required to increase alternative
          minimum taxable income by 75% of the excess of current earnings
          and profits (with certain adjustments) over alternative minimum
          taxable income (determined without regard to earnings and profits
          adjustments or the alternative tax net operating loss deduction).

               Redemption Premium

               Under Section 305(c) of the Code and the applicable Treasury
          regulations thereunder, if the redemption price of ICG Preferred
          Stock exceeds its issue price, the difference ("redemption
          premium") may be taxable as a constructive distribution of
          additional ICG Preferred Stock to Funding (treated as a dividend
          to the extent of ICG's current and accumulated earnings and
          profits and otherwise subject to the treatment described above
          for distributions) over a certain period. Because the ICG
          Preferred Stock provides for an optional right of redemption by
          ICG at a price in excess of the issue price, Funding could be
          required to recognize such redemption premium under a constant
          interest rate method if, based on all of the facts and
          circumstances, the optional redemption is more likely than not to
          occur. If stock may be redeemed at more than one time, the time
          and price at which such redemption is most likely to occur must
          be determined based on all of the facts and circumstances.
          Applicable Treasury regulations provide a "safe harbor" under
          which a right to redeem will not be treated as more likely than
          not to occur if (i) the issuer (i.e., ICG) and the stockholder
          (i.e., Funding) are not related within the meaning of the
          Treasury regulations; (ii) there are no plans, arrangements or
          agreements that effectively require, or are intended to compel,
          the issuer to redeem the stock (disregarding, for this purpose, a
          separate mandatory redemption) and (iii) exercise of the right to
          redeem would not reduce the yield of the stock, as determined
          under the Treasury regulations. Further, the Treasury regulations
          provide that such redemption premium is not taxable as a
          constructive distribution if it is solely in the nature of a
          penalty for premature redemption. A redemption premium is solely
          in the nature of a penalty for premature redemption if it is paid

                                      42
     <PAGE>

          as a result of changes in economic or market conditions over
          which neither the issuer nor the holder has control. Regardless
          of whether the optional redemption is more likely than not to
          occur or whether the redemption premium is solely in the nature
          of a penalty for premature redemption, constructive dividend
          treatment will not result if the redemption premium does not
          exceed a de minimis amount. Based on the Treasury regulations,
          ICG intends to take the position that the existence of ICG's
          optional redemption right will not result in a constructive
          distribution to Funding. If the IRS were to successfully assert
          that a constructive distribution occurred, any resulting income
          would be allocated to the Preferred Securityholders without the
          receipt of any cash related thereto.

               Adjustment of Exchange Rate

               Treasury Regulations promulgated under Section 305 of the
          Code would treat Funding as having received a constructive
          distribution from ICG in the event the exchange ratio for the ICG
          Preferred Stock is adjusted if (i) as a result of such
          adjustment, the proportionate interest (measured by the quantum
          of Common Stock into which the ICG Preferred Stock is
          exchangeable) of Funding in the assets or earnings and profits of
          ICG is increased, and (ii) the adjustment is not made pursuant to
          a bona fide and reasonable antidilution formula. An adjustment in
          the exchange rate would not be considered made pursuant to such
          formula if the adjustment is made to compensate for certain
          taxable distributions with respect to the Common Stock. Thus,
          under certain circumstances, an adjustment in the exchange rate
          of the ICG Preferred Stock, may result in deemed dividend income
          to Funding to the extent of the current or accumulated earnings
          and profits of ICG. Funding (and, in turn, the Preferred
          Securityholders) would be required to include such deemed
          dividend income in gross income but would not receive any cash
          related thereto. 

               Redemption of ICG Preferred Stock

               A redemption of the ICG Preferred Stock, in whole or in
          part, for cash will be a taxable transaction on which Funding
          (and, in turn, the Preferred Securityholders) will generally
          recognize capital gain or loss equal to the difference between
          the cash received and its adjusted tax basis in the redeemed
          stock (except to the extent of amounts received on the exchange
          that are attributable to declared dividends, which will be
          treated in the same manner as distributions described above).
          Such gain or loss will be long term if Funding's holding period
          in the ICG Preferred Stock exceeds one year. To the extent that
          ICG redeems the ICG Preferred Stock, in whole or in part,
          utilizing Common Stock plus cash, Funding (and, in turn, the
          Preferred Securityholders) should recognize gain equal to the
          lesser of (i) the gain that would have been recognized if only
          cash had been utilized in the redemption (as described above) and
          (ii) the amount of cash actually utilized in such redemption. If
          only Common Stock is utilized by ICG in the redemption, no gain
          or loss should be recognized by Funding. Funding should have a
          tax basis in the Common Stock received equal to its tax basis in
          the ICG Preferred Stock redeemed increased by any gain recognized
          as a result of any cash given in the redemption and decreased by
          the amount of cash received. The holding period in the ICG
          Preferred Stock should be tacked to the Common Stock received.
          The tax effect of the resulting redemption of the Preferred
          Securities is discussed below under "--Disposition of Preferred
          Securities."

               To the extent that either ICG exercises its right to redeem
          the ICG Preferred Stock, in whole or in part, pursuant to a
          Provisional Redemption, or a holder of Preferred Securities
          exercises its Exchange Right, ICG will redeem from Funding ICG
          Preferred Stock in exchange for Common Stock and exchange Common
          Stock for a portion of the Treasury Strips held by Funding. The
          tax consequences associated with the redemption of ICG Preferred
          Stock for Common Stock are described above. The tax consequences
          associated with liquidating distribution by Funding of Common
          Stock to a Preferred Securityholder are described above. See
          "--Treatment of Distributions by Funding." The exchange by Funding
          of Treasury Strips for Common Stock should constitute a taxable
          purchase of such shares by Funding. Funding and, in turn, the
          Preferred Securityholders should recognize gain on such purchase
          to the extent that the fair market value of the Treasury Strips
          exceeds the tax basis allocable to that portion of the Treasury
          Strips being redeemed and should recognize loss to the extent the
          tax basis allocable to that portion of the Treasury Strips
          exceeds the fair market value of the Treasury Strips being
          redeemed. In addition, the Common Stock acquired through the
          exchange of Treasury Strips should have a tax basis equal to its
          fair market value on the date of such exchange.

               Disposition of Preferred Securities

               Gain or loss will be recognized on a sale of Preferred
          Securities, including a redemption for cash (but not including an
          exchange with Funding of Preferred Securities for Common Stock),
          equal to the difference between the amount realized and the
          Preferred Securityholder's tax basis for the Preferred Securities
          sold. The Preferred Securityholder's adjusted tax basis in its
          Preferred Securities will be adjusted prior to the sale to
          reflect such holder's pro-rata share of Funding's income, gains,
          losses or deductions that flowed through prior to such
          disposition (including gain or loss resulting from a redemption
          of the ICG Preferred Stock). Gain or loss recognized by a
          Preferred Securityholder on the sale or exchange of Preferred
          Securities held for more than one year will generally be taxable
          as long-term capital gain or loss. Generally, the maximum
          effective United States federal corporate income tax rate for all
          types of income, including dividends (after the application of
          the dividends-received deduction), interest income and capital
          gains, is 35%. The maximum effective United States federal
          individual income tax rate applicable (i) to interest and
          dividend income is 39.6% and (ii) to gains resulting from the
          sale of capital assets held for longer than one year but less
          than 18 months is 28%. The maximum effective United States
          federal individual income tax rate on long-term capital gains
          will decrease to 20% if the Preferred Securities are held for
          more than 18 months. Beginning in the year 2006, capital assets
          held for more than five years will qualify for an 18% maximum
          effective United States federal individual income tax rate.

               A Preferred Securityholder should not recognize gain or loss
          upon the exchange with Funding of Preferred Securities for Common
          Stock (whether pursuant to an exchange initiated by the holder or
          following redemption by ICG of the ICG Preferred Stock) except to
          the extent the holder receives cash or to the extent of a gain or
          loss realized by Funding on its resulting exchange of its
          Treasury Strips for Common Stock. A Preferred Securityholder
          should only recognize gain upon the receipt of cash to the extent
          such cash received exceeds the Preferred Securityholder's tax
          basis in its Preferred Securities. See "--Treatment of
          Distributions by Funding." A Preferred Securityholder's tax basis
          in the Common Stock received upon exchange would be equal to such
          holder's tax basis in the Preferred Securities delivered for
          exchange reduced by any cash which is received upon such
          exchange. Inasmuch as a Preferred Securityholder who exchanges
          its Preferred Securities prior to a redemption remains entitled
          to receive a Dividend Make-Whole Payment (to the extent of a
          subsequent Provisional Redemption by Funding on or before
          November 15, 2000) it is unclear how such holder should allocate
          its tax basis in the Preferred Security exchanged to the Common
          Stock received. Funding intends to take the position that the
          contingent right to receive Dividend Make-Whole Payments does not
          affect the calculation of its tax basis in the Common Stock (as
          described above). Consequently, based on this position, to the
          extent such exchanging holder subsequently receives a Dividend
          Make-Whole Payment, such payment should result in capital gain of
          an equal amount. A Preferred Securityholder's holding period in
          the Common Stock received upon exchange should include the
          Preferred Securityholder's holding period in the Preferred
          Securities delivered.

               Preferred Securityholders should be aware that the tax
          treatment of the exchange feature of the Preferred Securities is
          not entirely clear and that the IRS might argue that, for tax
          purposes, Funding's exchange of ICG Preferred Stock into Common
          Stock (and Funding's subsequent distribution of such stock to a
          holder) should be treated as an exchange by the Preferred
          Securityholder of its Preferred Securities against ICG directly
          for Common Stock. While unlikely, if this argument were asserted
          and sustained, the conversion of the Preferred Securities by a
          Preferred Securityholder for Common Stock would be a taxable
          transaction in which a Preferred Securityholder would recognize
          capital gain or loss.

               Allocations Between Transferors and Transferees 

               In general, Funding's taxable income and losses will be
          determined annually, will be prorated on a monthly basis and will
          be subsequently apportioned among the holders of the Preferred
          Securities in proportion to the number of Preferred Securities
          owned by each of them as of the first business day of such month.
          As a result, a holder of Preferred Securities may be allocated
          income, gain, loss and deduction accrued after the date of
          transfer. 

               The use of this method may not be permitted under existing
          Treasury Regulations. Accordingly, counsel is unable to opine on
          the validly of this method of allocating income and deductions
          between the transferors and the transferees of Preferred

                                      44
     <PAGE>

          Securities. If this method is not allowed under the Treasury
          Regulations (or only applies to transfers of less than all of the
          holder's interest), taxable income or losses of Funding might be
          reallocated among the holders of the Preferred Securities
          (including transferors and transferees). Funding is authorized to
          revise its method of allocation between transferors and
          transferees (as well as among partners whose interests otherwise
          vary during a taxable period) to conform to a method permitted
          under future Treasury Regulations.

               A holder who owns Preferred Securities at any time during a
          quarter and who disposes of such Preferred Securities prior to
          the record date set for a cash distribution with respect to such
          quarter will be allocated items of Partnership income, gain, loss
          and deductions attributable to such quarter but will not be
          entitled to receive that cash distribution.


          INFORMATION TO SECURITYHOLDERS AND AUDIT REQUIREMENTS

               Funding will furnish each Preferred Securityholder with an
          information statement each year setting forth such Preferred
          Securityholder's allocable share of income for the prior calendar
          year. Funding is required to furnish this statement as soon as
          practicable following the end of the year, but in any event prior
          to March 31. 

               Any person who holds Preferred Securities as a nominee for
          another person is required to furnish to Funding (a) the name,
          address and taxpayer identification number of the beneficial
          owner and the nominee; (b) information as to whether the
          beneficial owner is (i) a person that is not a United States
          person, (ii) a foreign government, an international organization
          or any wholly-owned agency or instrumentality of either of the
          foregoing or (iii) a tax-exempt entity; (c) the amount and
          description of Preferred Securities held, acquired or transferred
          for the beneficial owner; and (d) certain information including
          the dates of acquisitions and transfers, means of acquisitions
          and transfers and acquisition cost for purchases, as well as the
          amount of net proceeds from sales. Brokers and financial
          institutions are required to furnish additional information,
          including whether they are United States person and certain
          information on Preferred Securities they acquire, hold or
          transfer for their own accounts. A penalty of $50 per failure (up
          to a maximum of $100,000 per calendar year) is imposed by the
          Code for the failure to report such information to Funding. The
          nominee is required to supply the beneficial owners of the
          Preferred Securities with the information furnished to Funding.

               ICG, as the tax matters partner, will be responsible for
          representing the Preferred Securityholders in any dispute with
          the IRS. The Code provides for administrative examination of a
          partnership as if the partnership were a separate and distinct
          taxpayer. Generally, the statute of limitations for partnership
          items does not expire before three years since the later of the
          filing or the last date for filing of the partnership information
          return. Any adverse determination following an audit of the
          return of Funding by the appropriate tax authorities could result
          in an adjustment of the returns of the Preferred Securityholders,
          and, under certain circumstances, a Preferred Securityholder may
          be precluded from separately litigating a proposed adjustment to
          the items of Funding. An adjustment could also result in an audit
          of a Preferred Securityholder's return and adjustments of items
          not related to the income and losses of Funding.

                                 PLAN OF DISTRIBUTION

               The Offered Securities may be sold from time to time to
          purchasers directly by the Selling Holders. Alternatively, the
          Selling Holders may from time to time offer the Offered
          Securities to or through underwriters, broker-dealers or agents,
          which may receive compensation in the form of underwriting
          discounts, concessions or commissions from the Selling Holders or
          the purchasers of such securities for whom they may act as
          agents. The Selling Holders, and any underwriters, broker-dealers
          or agents that participate in the distribution of Offered
          Securities, may be deemed to be "underwriters" within the meaning
          of the Securities Act, and any profit on the sale of such
          securities and any discounts, concessions, commissions or other
          compensation received by any such underwriter, broker-dealer or
          agent may be deemed to be underwriting discounts and commissions
          under the Securities Act.

               The Offered Securities may be sold from time to time in one
          or more transactions at fixed prices, at prevailing market prices
          at the time of sale, at varying prices determined at the time of
          sale or at negotiated prices. The sale of the Offered Securities
          may be effected in transactions (which may involve crosses or
          block transactions) (i) on any national securities exchange or
          quotation service on which the Offered Securities may be listed
          or quoted at the time of sale, (ii) in the over-the-counter
          market, (iii) in transactions otherwise than on such exchanges or
          in the over-the-counter market or (iv) through the writing of
          options. At the time a particular offering of the Offered
          Securities is made, a Prospectus Supplement, if required, will be
          distributed which will set forth the aggregate amount and type of
          Offered Securities being offered and the terms of the offering,
          including the name or names of any underwriters, broker-dealers
          or agents, any discounts, commissions and other terms
          constituting compensation from the Selling Holders and any
          discounts, commissions, or concessions allowed or reallowed or
          paid to broker-dealers.

               To comply with the securities laws of certain jurisdictions,
          if applicable, the Offered Securities will be offered or sold in
          such jurisdictions only through registered or licensed brokers or
          dealers. In addition, in certain jurisdictions the Offered
          Securities may not be offered or sold unless they have been
          registered or qualified for sale in such jurisdictions or any
          exemption from registration or qualification is available and is
          complied with.

               The Selling Holders will be subject to applicable provisions
          of the Exchange Act and the rules and regulations thereunder,
          which provisions may limit the timing of purchases and sales of
          any of the Offered Securities by the Selling Holders. The
          foregoing may affect the marketability of such securities.

               Pursuant to the Registration Rights Agreement, the Company
          shall bear all reasonable fees and expenses customarily borne by
          issuers in a non-underwritten secondary offering by selling
          security holders or in an underwritten offering, as the case may
          be, incurred in connection with the performance of its
          obligations under the Registration Rights Agreement; provided,
          however, that the Selling Holders will pay all underwriting
          discounts and selling commissions, if any. The Selling Holders
          will be indemnified by the Company and Funding, jointly and
          severally, against certain civil liabilities, including certain
          liabilities under the Securities Act, or will be entitled to
          contribution in connection therewith.

          ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS

          INDEMNIFICATION BY ICG OF ITS DIRECTORS AND OFFICERS

             The Certificate of Incorporation of ICG Communications, Inc.
          ("ICG") provides that ICG will to the fullest extent permitted by
          the General Corporation Law of the State of Delaware (the "GCL"),
          as amended from time to time, indemnify all persons whom it may
          indemnify pursuant thereof. ICG's By-laws contain a similar
          provisions requiring indemnification of ICG's 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 ICG 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 ICG, 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 ICG unless and only to
          the extent that the Court of Chancery or the court in which such
          action or suit was brought shall determine upon application that,
          despite the adjudication of liability but in view of all the
          circumstances of the case, such person is fairly and reasonably
          entitled to indemnity for such expenses. 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's Certificate of Incorporation contains a provision limiting
          the personal liability of ICG's directors for monetary damages
          for certain breaches of their fiduciary duty. ICG has
          indemnification insurance under which directors and officers are
          insured against certain liability that may incur in their
          capacity as such.

          INDEMNIFICATION BY FUNDING OF ITS MANAGER

             ICG is the Manager of Funding and, therefore, officers and
          directors of ICG engaging in activities on behalf of Funding
          would be entitled to benefits of the indemnification rights of
          ICG described above.

             Pursuant to the Operating Agreement of Funding, the Manager
          will be entitled to indemnification from Funding to the fullest
          extent permitted by applicable law, for any loss, damage or claim
          incurred by the Manager by reason of any act or omission
          performed or omitted by the Manager in good faith on behalf of
          Funding and in a manner reasonably believed to be within the
          scope of authority conferred on the Manager by the Operating
          Agreement; provided, however, that any indemnity under Section
          16.7 of the Operating Agreement will be provided out of and to
          the extent of Funding's assets only, and no member of Funding
          will have any personal liability on account thereof. The right of
          indemnification pursuant to Section 16.7 of the Operating
          Agreement will include the right to be paid, in advance, or
          reimbursed by Funding for the reasonable expenses incurred by the
          Manager who was, is, or is threatened to be made a named
          defendant or respondent in a proceeding.

          ITEM 17. UNDERTAKINGS.

          The undersigned Registrants hereby undertake:

          (1)  To file, during any period in which offers or sales are
          being made of the securities registered hereby, a post-effective
          amendment of this Registration Statement:

               (i)  to include any prospectus required by Section 10(a)(3)
          of the Securities Act of 1933, as amended (the "Securities Act");

               (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; and

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

          provided, however, that paragraphs (1)(i) and (1)(ii) do not
          apply if the information required to be included in a post-
          effective amendment by those paragraphs is contained in periodic
          reports filed by the Registrants pursuant to Section 13 or
          Section 15(d) of the Securities Exchange Act of 1934, as amended
          (the "Exchange Act"), that are incorporated by reference in the
          Registration Statement.

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

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

          (4)  That, for the purpose of determining any liability under the
          Securities Act, each filing of ICG's annual report pursuant to
          Section 13(a) or Section 15(d) of the Exchange Act (and, where
          applicable, each filing of any employee benefit plan's annual
          report pursuant to Section 15(d) of the Exchange Act) that is
          incorporated by reference in the Registration Statement shall be
          deemed to be a new Registration Statement relating to the
          securities offered therein, and the offering of such securities
          at that time shall be deemed to be the initial bona fide offering
          thereof.

          (5)  Insofar as indemnification for liabilities arising under the
          Securities Act may be permitted to directors, officers and
          controlling persons of the Registrants pursuant to the provisions
          described in Item 15 (other than the provisions relating to
          insurance), or otherwise, the Registrants have been advised that
          in the opinion of the Securities and Exchange Commission such
          indemnification is against public policy expressed in the
          Securities Act and is, therefore, unenforceable. In the event
          that a claim for indemnification against such liabilities (other
          than the payment by the Registrants of expenses incurred or paid
          by a director, officer or controlling person of the Registrants
          in the successful defense of any action, suit or proceeding) is
          asserted by such director, officer or controlling person in
          connection with the securities being registered, the Registrants
          will, unless in the opinion of its counsel the matter has been
          settled by controlling precedent, submit to a court of
          appropriate jurisdiction the question whether such
          indemnification by it is against public policy as expressed in
          the Securities Act and will be governed by the final adjudication
          of such issue.

               SECTION 2.7.  ADMISSION OF MEMBERS.

                    (a)  A Person shall be admitted as a Member and shall
          become bound by the terms of this Agreement, without execution of
          this Agreement, if such Person (or a representative authorized by
          such Person orally, in writing or by other action such as payment
          for an Interest) complies with the conditions for becoming a
          Member as set forth in Section 2.7(b) and requests (which request
          shall be deemed to have been made upon acquisition of an Interest
          directly from the Company or upon an assignment of an Interest
          from another Person) that the records of the Company reflect such
          admission. The Company shall be promptly notified of any
          assignment of an Interest.

                    The Company will reflect the admission of a Member in
          the records of the Company as soon as is reasonably practicable
          after either of the following events: (i) in the case of a Person
          acquiring an Interest directly from the Company, at the time of
          payment therefor, and (ii) in the case of an assignment, upon
          notification thereof (the Company being entitled to assume, in
          the absence of knowledge to the contrary, that proper payment has
          been made by the assignee).

                    (b)  Subject to the restrictions on transfer of Common
          Securities set forth in Sections 7.1(e) and 14.1 of this
          Agreement, whether acquiring an Interest directly from the
          Company or by assignment, a Person shall be admitted as a Member
          upon the acquisition or assignment, as the case may be, of such
          Interest and the reflection of such Person's admission as a
          Member on the registration books maintained by or on behalf of
          the Company. The consent of any other Member or the Manager shall
          not be required for the admission of a Member.

               SECTION 2.8.  MERGER, CONSOLIDATION, ETC. OF THE COMPANY.
          The Company may not consolidate with, merge with or into, or be
          replaced by, or convey, transfer or lease its properties and
          assets as an entirety or substantially as an entirety to any
          Person, except with the prior approval of Preferred Members
          holding not less than a Majority in Liquidation Preference of the
          outstanding Preferred Securities of each series or except as set
          forth in this Section 2.8.  The Company may, without the consent
          of Preferred Members, consolidate with, merge with or into, or be
          replaced by, or convey, transfer or lease its assets as an
          entirety or substantially as an entirety to, a limited liability
          company, limited partnership or trust organized as such under the
          laws of any state of the United States of America or the District
          of Columbia, provided that (i) such successor entity either (x)
          expressly assumes all of the obligations of the Company under the
          Preferred Securities or (y) substitutes for the Preferred
          Securities of each series other securities having substantially
          the same terms as such Preferred Securities of each series (the
          "Successor Securities") so long as the Successor Securities rank,
          with respect to participation in the profits or assets of the
          successor entity, at least as high as the Preferred Securities of
          the related series rank with respect to payment of dividends and
          distribution of assets upon the liquidation, dissolution or
          winding-up of the Company, (ii) ICG expressly acknowledges such
          successor entity as the holder of the ICG Preferred Stock
          relating to such Preferred Securities and its obligations under
          the Guarantee with respect to the Successor Securities, (iii)
          such merger, consolidation, replacement, conveyance, transfer or
          lease does not cause the Preferred Securities or the Successor
          Securities, if any, to be delisted (or, in the case of any
          Successor Securities, to fail to be listed) by any national
          securities exchange or other organization on which such Preferred
          Securities are then listed, (iv) such merger, consolidation,
          replacement, conveyance, transfer or lease does not cause the
          Preferred Securities or Successor Securities, if any, to be
          downgraded (or put on a "watch list" for possible downgrading) by
          any "nationally recognized statistical rating organization," as
          that term is defined by the Securities and Exchange Commission
          for purposes of Rule 436(g)(2) under the Securities Act of 1933,
          as amended, (v) such merger, consolidation, replacement,
          conveyance, transfer or lease does not adversely affect the
          powers, preferences and other special rights of Preferred Members
          or the holders of the Successor Securities, if any, in any
          material respect (other than with respect to any dilution of the
          holders' interest in the new entity) and (vi) prior to such
          merger, consolidation, replacement, conveyance, transfer or
          lease, ICG has received an opinion of nationally recognized
          independent legal counsel to the Company experienced in such
          matters to the effect that (x) such successor entity will be
          treated as a partnership or as a grantor trust, as appropriate,
          for federal income tax purposes, (y) following such merger,
          consolidation, replacement, conveyance, transfer or lease, ICG
          and such successor entity will be in compliance with the
          Investment Company Act of 1940, as amended, without registering
          thereunder as an investment company and (z) such merger,
          consolidation, replacement, conveyance, transfer or lease will
          not adversely affect the limited liability of the Preferred
          Members or the holders of the Successor Securities, if any, or
          result in federal income tax liability to such Preferred Members
          or holders other than with respect to any fractional share
          interests converted into cash.

                                     ARTICLE III
                          PURPOSE AND POWERS OF THE COMPANY

                    The purposes of the Company are (a) to issue Interests
          and to use at least 85% all of the proceeds from the issuance
          thereof (the "Offering") and the related capital contributions to
          purchase shares of ICG Preferred Stock from ICG, (b) to invest up
          to 15% of such proceeds in Treasury strips and other U.S.
          Government Securities and (c) except as otherwise limited herein,
          to enter into, make and perform all contracts and other
          undertakings, and to take any and all actions necessary,
          appropriate, proper, advisable, incidental or convenient to or
          for the furtherance of the purpose of the Company as set forth
          herein.  On the closing date of the issuance of the Preferred
          Securities (the "Closing Date"), the Manager, on behalf of the
          Company, shall purchase, and place in escrow, Treasury strips in
          an amount sufficient to fund the cash payment of the first 13
          dividends on the Preferred Securities.  From the Closing Date to
          a date selected by the Manager, on behalf of the Company (the
          "Funding Date"), that is no more than six months after the
          Closing Date, the entire proceeds of the Offering, less the
          amount used to purchase Treasury strips, shall be invested by the
          Manager, on behalf of the Company, in U.S. Government Securities. 
          On the Funding Date, the Manager, on behalf of the Company, shall
          use the earnings of and principal of such U.S. Government
          Securities to pay $97.75 million to ICG as consideration for ICG
          Preferred Stock.  In the event such earnings and principal do not
          equal $97.75 million, the Company shall receive a distribution on
          the ICG Preferred Stock from ICG of shares of ICG Common Stock in
          a number that will be sufficient, when sold by the Company in the
          open market, to eliminate such cash shortfall.  Dividends on the
          ICG Preferred Stock will, at the option of ICG, be payable either
          in cash or in shares of ICG Common Stock.  Such shares may, at
          the option of the Manager, on behalf of the Company, be used to
          pay dividends on the Preferred Securities or sold to raise funds
          to pay cash dividends on the Preferred Securities.  The Company
          may not conduct any other business or operations or voluntarily
          incur any obligations except as contemplated by this Agreement.

                                      ARTICLE IV
                 CAPITAL CONTRIBUTIONS, ALLOCATIONS AND DISTRIBUTIONS

               SECTION 4.1.  FORM OF CONTRIBUTION. The contribution of a
          Member to the Company may, as determined by the Manager in its
          discretion, be in cash, a promissory note or other legal
          consideration. 

               SECTION 4.2.  CONTRIBUTION BY THE COMMON MEMBER.  The Common
          Member shall make an initial contribution to the Company in
          connection with the purchase of one Common Security so as to
          cause its Common Security to be entitled to .01% of all interests
          in the capital, income, gain, loss, deduction and credit of the
          Company at all times, provided, however, that in no event shall
                                --------  -------
          total cash contributions by the Common Member be an amount in
          excess of $1.00 in the aggregate.

               SECTION 4.3.  CONTRIBUTIONS BY THE PREFERRED MEMBERS. The
          Preferred Members shall make contributions to the Company in
          accordance with the applicable terms of Section 7.1 of this
          Agreement. Preferred Members, in their capacity as Members of the
          Company, shall not be required to make any additional
          contributions to the Company and shall have no additional
          liability solely by reason of being Preferred Members (subject to
          their obligation to return distributions wrongfully distributed
          to them as required by applicable law).

               SECTION 4.4.  INVESTMENT OF CAPITAL CONTRIBUTIONS.  On the
          Closing Date, the Manager shall establish an escrow account (the
          "Escrow Account") with Norwest Bank Colorado, National
          Association, as escrow agent (the "Escrow Agent") pursuant to the
          terms of an Escrow Agreement, dated the Closing Date, between the
          Company and the Escrow Agent.  The Manager shall deposit with the
          Escrow Agent, in accordance with the Escrow Agreement, the
          Treasury strips purchased pursuant to Article III and the Manager
          on behalf of the Company shall pledge the Treasury strips to the
          Escrow Agent for the benefit of the Preferred Members pursuant to
          the terms of the Escrow Agreement.

               SECTION 4.5.  CAPITAL ACCOUNTS. An individual capital
          account (a "Capital Account") shall be established and maintained
          on the books of the Company for each Member in compliance with
          Treasury Regulation Sections 1.704-1(b)(2)(iv) and 1.704-2, as
          amended. Subject to the preceding sentence, each Capital Account
          will be increased by the amount of the capital contributions made
          by, and the Net Income allocated to, such Member and reduced by
          the amount of distributions made by the Company and Net Losses
          allocated to the Member. In addition, a Member's Capital Account
          shall be increased or decreased, as the case may be, for any
          items specially allocated to such Member under Section 4.7 of
          this Agreement.

               SECTION 4.6.  GENERAL ALLOCATIONS. After giving effect to
          the special allocations set forth in Section 4.7 of this
          Agreement:

                    (a)  Except as provided in Sections 4.6(c) and (d), the
               Company's Net Income for each Fiscal Period shall be
               allocated, as of the close of business on the last day of
               such Fiscal Period, as follows: 

                         (i)  First, to the Preferred Members, in
                    proportion to the number of Preferred Securities held
                    by each such Member, in an amount equal to the excess
                    of (x) the amount of all dividends accrued on such
                    Preferred Member's Preferred Securities from the
                    issuance of such Preferred Securities through the close
                    of business on the last day of such Fiscal Period
                    (whether or not paid), over (y) the amount of Net
                    Income allocated to such Preferred Member (and his
                    predecessors in interest) in respect of such Preferred
                    Securities pursuant to this Section 4.6(a)(i) for all
                    prior Fiscal Periods.

                         (ii) Second, to each Preferred Member, in an
                    amount equal to the excess of (x) the amount of all Net
                    Losses allocated to such Preferred Member from the date
                    of issuance of such Preferred Member's Preferred
                    Securities through the close of business for such
                    Fiscal Period pursuant to Section 4.6(b)(ii) over (y)
                    the amount of Net Income allocated to such Preferred
                    Member (and his predecessors in interest) in respect of
                    such Preferred Securities pursuant to this Section
                    4.6(a)(ii) for all prior Fiscal Periods.

                         (iii)     Any remaining Net Income shall be
                    allocated to the Common Member.

                    (b)  Except as provided in Section 4.6(d), the
               Company's Net Loss for each Fiscal Period shall be
               allocated, as of the close of business on the record date
               for such Fiscal Period, as follows:

                         (i)  First, to the Common Member until the balance
                    of the Common Member's Adjusted Capital Account is
                    reduced to zero.

                         (ii) Second, to the Preferred Members (in
                    proportion to their respective aggregate Adjusted
                    Capital Account balances) until their Adjusted Capital
                    Account balances are reduced to zero.

                         (iii)     Any remaining Net Loss shall be
                    allocated to the Common Member.

                    (c)  Notwithstanding any other allocation provided for
          in this Agreement, any gain realized on an exchange or
          disposition of ICG Preferred Stock or U.S. Government Securities
          (whether pursuant to a redemption or otherwise) shall be
          allocated to the Preferred Members in proportion to the number of
          Preferred Securities owned by each such member.

                    (d)  The Manager may make such changes to the
               allocations in Sections 4.6(a), 4.6(b) and 4.6(c) as it
               deems reasonably necessary so that, immediately prior to the
               Company's liquidation (or the exchange of Preferred
               Securities for shares of ICG Common Stock), the positive
               balances in the Capital Accounts of the Preferred Members
               shall, to the maximum extent possible, equal their
               respective Liquidation Distributions; provided, however,
                                                     --------  -------
               that no allocation pursuant to this Section 4.6(c) may
               result in the Manager being required to make a capital
               contribution pursuant to this Agreement or otherwise, other
               than that set forth in Section 4.2.

                    (e)  Notwithstanding any other provision of this
          Agreement to the contrary, the allocation of Net Losses to any
          Preferred Member shall not reduce the Liquidation Distribution of
          the Preferred Securities held by such Preferred Member.

               SECTION 4.7.  SPECIAL ALLOCATIONS.

                    (a)  If a Preferred Member delivers a Notice of
          Exchange to the Exchange Agent pursuant to the appropriate
          Preferred Securities Designation, which instructs the Exchange
          Agent to exchange Preferred Securities for shares of ICG Common
          Stock, such Preferred Member shall be allocated its pro rata
          share of any dividend income accruing on a daily basis on the ICG
          Preferred Stock pursuant to Section 305(c) of the Code or
          original issue discount accruing on a daily basis until the date
          of such exchange, but only to the extent such income was not
          previously allocated to the Members in a prior Fiscal Period
          under Section 4.6 of this Agreement or this Section 4.7.

                    (b)  If the Exchange Agent exchanges all of the
          Preferred Securities of a particular series for shares of ICG
          Common Stock, pursuant to the appropriate Preferred Securities
          Designation, the Preferred Members of such series shall be
          allocated (in proportion to the liquidation preferences of such
          Preferred Securities held by each such Preferred Member) any
          dividend income accruing on a daily basis on the ICG Preferred
          Stock pursuant to Section 305(c) of the Code or original issue
          discount accruing on a daily basis so exchanged until the date of
          such exchange, but only to the extent such income was not
          previously allocated to the Members in prior Fiscal Periods under
          Section 4.6 of this Agreement or this Section 4.7.

                    (c)  If the Company is deemed to receive a dividend
          under Section 305(c) of the Code with respect to any series of
          ICG Preferred Stock or original issue discount with respect to
          debt obligations it is holding, the Preferred Members holding
          Preferred Securities of the related series shall be allocated (in
          proportion to the liquidation preferences of such Preferred
          Securities held by each such Preferred Member) such income.

                    (d)  All items of loss and deduction in respect of
          expenses incurred by or on behalf of the Company and paid by the
          Common Member (or out of the Common Member's share of
          distributions) shall be allocated entirely to the Common Member.

                    (e)  For purposes of determining the Net Income, Net
          Loss or any other items allocable to any Fiscal Period, Net
          Income, Net Loss and any such other items shall be determined on
          a daily, monthly or other basis, as determined by the Manager
          using any method that is permissible under Section 706 of the
          Code and the Treasury Regulations promulgated thereunder. Unless
          otherwise specified, such Net Income, Net Loss or other items
          shall be determined for each Fiscal Period.

                    (f)  Notwithstanding anything to the contrary that may
          be expressed or implied in this Article IV, the interest of the
          Common Member, in the aggregate, in each item of income, gain,
          loss, deduction and credit will be equal to at least (i) at any
          time that aggregate capital contributions to the Company are
          equal to or less than $50,000,000, 1% of each such item and (ii)
          at any time that aggregate capital contributions to the Company
          are greater than $50,000,000, at least 1% multiplied by a
          fraction (not exceeding one and not less than 0.2), the numerator
          of which is $50,000,000 and the denominator of which is the
          lesser of the aggregate balances of the Capital Accounts of all
          Members at such time and the aggregate capital contributions to
          the Company of all Members at such time.

                    (g)  Notwithstanding any other provision of this
          Agreement to the contrary, the allocation of Net Losses to any
          Preferred Member shall not reduce the Liquidation Distribution of
          the Preferred Securities held by such Preferred Member.

               SECTION 4.8.  ALLOCATIONS FOR INCOME TAX PURPOSES.  The
          income, gains, losses, deductions and credits of the Company
          shall be allocated in the same manner as the items entering into
          the computation of Net Income and Net Loss are allocated under
          Section 4.6 of this Agreement or as such items are otherwise
          allocated under Section 4.7 of this Agreement; provided, however,
                                                         --------  -------
          that solely for federal, state and local income and franchise tax
          purposes, but not for book or Capital Account purposes, income,
          gain, loss and deductions with respect to any property properly
          carried on the Company's books at a value other than the tax
          basis of such property shall be allocated in a manner determined
          in the Manager's discretion, so as to take into account
          (consistently with the principles of Section 704(c) of the Code)
          the difference between such property's book value and its tax
          basis.

               SECTION 4.9.  WITHHOLDING. The Manager, on behalf of the
          Company, shall comply with withholding requirements under
          federal, state and local law and shall remit amounts withheld to
          and file required forms with applicable jurisdictions. To the
          extent that the Company is required to withhold and pay over any
          amounts to any authority with respect to distributions or
          allocations to any Member, the amount withheld shall be deemed to
          be a distribution in the amount of the withholding to the Member.
          In the event of any claimed over-withholding, Members shall be
          limited to an action against the applicable jurisdiction. If the
          amount withheld was not withheld from actual distributions, the
          Manager, on behalf of the Company, may reduce subsequent
          distributions by the amount of such withholding. Each Member
          agrees to furnish the Company with such representations and forms
          as shall reasonably be requested by the Company to assist it in
          determining the extent of, and in fulfilling, its withholding
          obligations.

               SECTION 4.10.  ALLOCATION OF DISTRIBUTIONS. The
          distributions of the Company shall, subject to the applicable
          terms of Sections 7.1, 9.1, 9.2, 9.3, 15.4 and 15.5 of this
          Agreement and of any series of Preferred Securities (including
          the preferential allocation of distributions, if any), be
          allocated entirely to the Common Member. 

               SECTION 4.11.  INTERESTS AS PERSONAL PROPERTY. Each Member
          hereby agrees that its Interest shall for all purposes be
          personal property. A Member has no interest in specific Company
          property.

                                      ARTICLE V
                                       MEMBERS

               SECTION 5.1.  POWERS OF MEMBERS. The Members shall have the
          power to exercise any and all rights or powers granted to the
          Members pursuant to the express terms of this Agreement and the
          terms of the interests held by such Members.

               SECTION 5.2.  PARTITION. Each Member waives any and all
          rights that it may have to maintain an action for partition of
          the Company's property.

               SECTION 5.3.  RESIGNATION. The Common Member shall have no
          right to withdraw from the Company. Any other Member may withdraw
          from the Company prior to the liquidation, dissolution or winding
          up of the Company only upon the assignment of its Interest
          (including any redemption, repurchase, exchange or other
          acquisition by the Company of such Interest) in accordance with
          the provisions of this Agreement. A withdrawing Member shall not
          be entitled to receive any distribution and shall not otherwise
          be entitled to receive the fair value of its Interest except as
          otherwise expressly provided for in this Agreement.

                                      ARTICLE VI
                                      MANAGEMENT

               SECTION 6.1.  MANAGEMENT OF THE COMPANY. Except as otherwise
          provided herein, the business and affairs of the Company shall be
          managed, and all actions required under this Agreement shall be
          determined, solely and exclusively by the Manager, which shall
          have all rights and powers on behalf and in the name of the
          Company to perform all acts necessary and desirable to the
          objects and purposes of the Company (subject to Article III).
          Without limiting the generality of the foregoing, the Manager, in
          its capacity as the Common Member and not by virtue of any
          delegation of management power from any Member, shall have
          (subject to Article III) the power on behalf of the Company to:

                    (a)  authorize and engage in transactions and dealings
          on behalf of the Company, including transactions and dealings
          with any Member (including the Common Member) or any Affiliate of
          any Member;

                    (b)  call meetings of Members or any class or series
          thereof;

                    (c)  issue Interests, including Common Securities,
          Preferred Securities and classes and series thereof, in
          accordance with this Agreement;

                    (d)  pay all expenses incurred in forming the Company;

                    (e)  lend money, with or without security, to ICG or
          any Affiliate thereof;

                    (f)  determine and make distributions (hereinafter
          sometimes referred to as "dividends"), in cash or otherwise, on
          Interests, in accordance with the provisions of this Agreement,
          the Delaware Act and, if applicable, each Preferred Securities
          Designation;

                    (g)  establish a record date with respect to all
          actions to be taken hereunder that require a record date to be
          established, including with respect to allocations, dividends and
          voting rights;

                    (h)  redeem, repurchase or exchange, on behalf of the
          Company, Interests which may be so redeemed, repurchased or
          exchanged;

                    (i)  appoint (and dismiss from appointment) attorneys
          and agents on behalf of the Company, and employ (and dismiss from
          employment) any and all persons providing legal, accounting or
          financial services to the Company, or such other employees or
          agents as the Manager deems necessary or desirable for the
          management and operation of the Company, including, without
          limitation, any Member (including the Common Member) or any
          Affiliate of any Member;

                    (j)  open accounts and deposit, maintain and withdraw
          funds in the name of the Company in banks, savings and loan
          associations, brokerage firms or other financial institutions;

                    (k)  effect a dissolution of the Company and act as
          liquidating trustee or the Person winding up the Company's
          affairs, all in accordance with the provisions of this Agreement,
          the Delaware Act and, if applicable, each Preferred Securities
          Designation;

                    (l)  bring and defend on behalf of the Company actions
          and proceedings at law or equity before any court or
          governmental, administrative or other regulatory agency, body or
          commission or otherwise;

                    (m)  prepare and cause to be prepared reports,
          statements and other relevant information for distribution to
          Members as may be required or determined to be necessary or
          desirable by the Manager from time to time;

                    (n)  prepare and file all necessary returns and
          statements and pay all taxes, assessments and other impositions
          applicable to the assets of the Company; and

                    (o)  execute all other documents or instruments,
          perform all duties and powers and do all things for and on behalf
          of the Company in all matters necessary or desirable or
          incidental to the foregoing.

                    The Manager is authorized and directed to conduct its
          affairs and to operate the Company in such a way that the Company
          will not be deemed to be an "investment company" required to be
          registered under the Investment Company Act of 1940, as amended.
          In this connection, the Manager is authorized to take any action
          not inconsistent with applicable law, this Agreement and the
          applicable Preferred Securities Designation and that the Manager
          determines in its discretion to be necessary or desirable for
          such purposes.

                    The expression of any power or authority of the Manager
          in this Agreement shall not in any way limit or exclude any other
          power or authority which is not specifically or expressly set
          forth in this Agreement. 

               SECTION 6.2.  RELIANCE BY THIRD PARTIES.  Persons dealing
          with the Company are entitled to rely conclusively upon the power
          and authority of the Manager herein set forth.

               SECTION 6.3.  NO MANAGEMENT BY ANY PREFERRED MEMBERS OR ICG.
          Except as otherwise expressly provided herein, no Preferred
          Member shall take part in the day-to-day management, operation or
          control of the business and affairs of the Company. Neither the
          Preferred Members, in their capacity as Preferred Members of the
          Company, nor ICG, in its capacity as the Common Member, shall be
          agents of the Company or have any right, power or authority to
          transact any business in the name of the Company or to act for or
          on behalf of or to bind the Company.

               SECTION 6.4.  BUSINESS TRANSACTIONS OF THE MANAGER WITH THE
          COMPANY. The Manager or its Affiliates may lend money to, act as
          surety, guarantor or endorser for, guarantee or assume one or
          more obligations of, provide collateral for, and transact other
          business with, the Company and, subject to applicable law, shall
          have the same rights and obligations with respect to any such
          matter as a Person who is not the Manager or an Affiliate
          thereof.

               SECTION 6.5.  OUTSIDE BUSINESSES. Any Member and/or the
          Manager in its capacity as same may possess an interest in other
          business ventures of any nature or description, independently or
          with others, similar or dissimilar to the business of the
          Company, and the Company and the Members shall have no rights by
          virtue of this Agreement in and to such independent ventures or
          the income or profits derived therefrom, and the pursuit of any
          such venture, even if competitive with the business of the
          Company, shall not be deemed wrongful or improper. No Member or
          Affiliate thereof shall be obligated to present any particular
          investment opportunity to the Company even if such opportunity is
          of a character that, if presented to the Company, could be taken
          by the Company, and any Member or Affiliate thereof shall have
          the right to take for its own account (individually or as a
          partner or fiduciary) or to recommend to others any such
          particular investment opportunity.

                                     ARTICLE VII
                      COMMON SECURITIES AND PREFERRED SECURITIES

               SECTION 7.1.  COMMON SECURITIES AND PREFERRED SECURITIES.

                    (a)  The Interests in the Company shall initially be
          divided into two classes, Common Securities and Preferred
          Securities.

                    (b)  The Preferred Securities may be issued from time
          to time in one or more series with such relative rights, powers,
          preferences, limitations and restrictions as may from time to
          time be established in a written action or actions of the Manager
          providing for the issue of such series of Preferred Securities as
          hereinafter provided. Authority is hereby expressly granted to
          the Manager, subject to the provisions of this Agreement, to
          authorize the issue of one or more series of Preferred Securities
          and to establish each such series by a written action or actions
          (including without limitation an amendment of this Agreement)

          such series and the distinctive designation thereof;

                    (ii) whether the Preferred Securities of such series
          shall have voting rights in addition to those set forth in this
          Agreement or required by law and, if so, the terms of such voting
          rights;

                    (iii)     the annual dividend rate (or method of
          calculation thereof), if any, on the Preferred Securities of such
          series, the conditions and dates upon which such dividends shall
          be payable and the ability of the Company, if any, to defer the
          dividend payment period for the Preferred Securities of such
          series, the dates from which such dividends shall accrue, the
          preference or relation, if other than pari passu, which such
          dividends have with respect to dividends payable on any other
          class or classes of Interests or on any other series of Preferred
          Securities, and whether such dividends shall be cumulative or
          noncumulative;

                    (iv) whether the Preferred Securities of such series
          shall be subject to redemption by the Company, and, if made
          subject to redemption, the times and other terms and conditions
          of such redemption (including the mandatory or optional nature of
          such redemption, whether such redemption shall be in whole and/or
          in part, and the amount and kind of consideration to be received
          upon such redemption);

                    (v)  the amount or amounts which shall be paid out of
          the assets of the Company to Preferred Members holding the
          Preferred Securities of such series upon voluntary or involuntary
          liquidation, dissolution or winding up of the Company, and any
          rights in addition to those set forth in this Agreement of the
          Preferred Members that hold Preferred Securities of such series
          upon the liquidation, dissolution or winding up of the Company;

                    (vi) whether or not the Preferred Securities of such
          series shall be subject to the operation of a retirement or
          sinking fund, and, if so, the extent to and manner in which any
          such retirement or sinking fund shall be applied to the purchase
          or redemption of the Preferred Securities of such series for
          retirement and the terms and provisions relative to the operation
          thereof;

                    (vii)     whether or not the Preferred Securities of
          such series shall be convertible into, or exchangeable for,
          Interests of any other class or classes, or of any other series
          of Preferred Securities, or securities of any other kind,
          including those issued by ICG or any of its Affiliates, and if so
          convertible or exchangeable, the terms and conditions of such
          conversion or exchange, including the price or prices or the rate
          or rates of conversion or exchange; the method, if any, of
          adjusting the same and the terms of any right to terminate such
          conversion or exchange privilege;

                    (viii)    any limitations and restrictions in addition
          to those set forth in this Agreement to be effective while any
          Preferred Securities of such series are outstanding upon the
          payment of dividends or other distributions on, and upon the
          purchase, redemption or other acquisition by the Company of,
          Common Securities or any other series of Preferred Securities;

                    (ix) any conditions or restrictions in addition to
          those set forth in this Agreement upon the issue of any
          additional Interests (including additional Preferred Securities
          of such series or Interests of any other series ranking pari
          passu with or senior to the Preferred Securities of such series
          as to the payment of dividends or distribution of assets on
          dissolution);

                    (x)  the times, prices and other terms and conditions
          for the offering of the Preferred Securities of such series; and 

                    (xi) any other relative rights, powers, preferences,
          limitations and restrictions as shall not be inconsistent with
          this Section 7.1.

                    In connection with the foregoing and without limiting
          the generality thereof, the Manager is hereby expressly
          authorized, without the vote or approval of any other Member, to
          take any action to create under the provisions of this Agreement
          a series of Preferred Securities that was not previously
          outstanding. Without the vote or approval of any other Member,
          the Manager may execute, swear to, acknowledge, deliver, file and
          record whatever documents may be required in connection with the
          issue from time to time of Preferred Securities in one or more
          series as shall be necessary, convenient or desirable to reflect
          the issue of such series. The Manager shall do all things it
          deems to be appropriate or necessary to comply with the Delaware
          Act and is authorized and directed to do all things it may deem
          to be necessary or permissible in connection with any future
          issuance, including compliance with any statute, rule, regulation
          or guideline of any federal, state or other governmental agency
          or any securities exchange.

                    Any action or actions taken by the Manager pursuant to
          the provisions of this paragraph (b) shall be deemed an amendment
          and supplement to and part of this Agreement.

                    (c)  All Preferred Securities shall rank senior to the
          Common Securities in respect of the right to receive dividends
          and the right to receive payments out of the assets of the
          Company upon voluntary or involuntary liquidation, dissolution or
          winding up of the Company. All Preferred Securities redeemed,
          purchased or otherwise acquired by the Company (including
          Preferred Securities surrendered for conversion or exchange)
          shall be cancelled and thereupon restored to the status of
          authorized but unissued Preferred Securities undesignated as to
          series.

                    (d)  No Member shall be entitled as a matter of right
          to subscribe for or purchase, or have any preemptive right with
          respect to, any part of any new or additional issue of Common
          Securities or Preferred Securities of any series whatsoever, or
          of securities convertible into any Common Securities or Preferred
          Securities of any series whatsoever, whether now or hereafter
          authorized and whether issued for cash or other consideration or
          by way of dividend.

                    (e)  Common Securities shall not be evidenced by any
          certificate or other written instrument, but shall only be
          evidenced by this Agreement. Common Securities shall be
          non-assignable and non-transferable, and may only be issued to
          and held by ICG (or a successor of ICG in accordance with the
          provisions of the Guarantee).  Any transfer or purported transfer
          of any Common Security shall be null and void. Preferred
          Securities shall be freely assignable and transferable.

                    (f)  Any Person purchasing Preferred Securities
          (whether from the Company or upon assignment) shall be admitted
          to the Company as a Preferred Member upon compliance with Section
          2.7 of this Agreement.

               SECTION 7.2.  PERSONS DEEMED PREFERRED MEMBERS. The Company
          may treat the Person in whose name any Preferred Certificate
          shall be registered on the books and records of the Company as a
          Preferred Member and the sole holder of such Preferred
          Certificate for purposes of receiving dividends and for all other
          purposes whatsoever and, accordingly, shall not be bound to
          recognize any equitable or other claims to or interest in such
          Preferred Certificate on the part of any other Person, whether or
          not the Company shall have actual or other notice thereof.

                                 VOTING AND MEETINGS

               SECTION 8.1.  VOTING RIGHTS OF HOLDERS OF PREFERRED
          SECURITIES.

                    (a)  Except as shall be otherwise provided in this
          Agreement, including without limitation, Section 16.1 hereof, or
          in the Preferred Securities Designation for any series of
          Preferred Securities and except as otherwise required by the
          Delaware Act, the Preferred Members holding Preferred Securities
          shall have, with respect to such Preferred Securities, no right
          or power to vote on any question or matter or in any proceeding
          or to be represented at, or to receive notice of, any meeting of
          Members.

                    (b)  If any proposed amendment to this Agreement or the
          Preferred Securities Designation for any series of Preferred
          Securities provides for, or the Manager otherwise proposes to
          effect:

                         (i)  any action that would have a material adverse
               effect on the powers, preferences or special rights of the
               Preferred Securities of such series, whether by way of
               amendment of this Agreement, such Preferred Securities
               Designation or otherwise (including, without limitation, the
               authorization or issuance of any Interests in the Company
               purporting to rank, as to payment of dividends or
               distribution of assets upon liquidation, dissolution or
               winding up of the Company, senior to the Preferred
               Securities of such series), or

                         (ii) the liquidation, dissolution or winding up of
               the Company (in any case other than in connection with the
               exchange of Preferred Securities of such series for other
               securities pursuant to the terms of such series of Preferred
               Securities),

          then the Preferred Members holding outstanding Preferred
          Securities of such series, together with, if any such amendment
          or action described in clause (i) above would materially
          adversely affect the powers, preferences or special rights of any
          Company Dividend Parity Securities or any Company Liquidation
          Parity Securities, the holders of such Company Dividend Parity
          Securities or such Company Liquidation Parity Securities, as the
          case may be, or, with respect to any such amendment or action
          described in clause (ii) above, the holders of all Company
          Liquidation Parity Securities, will be entitled to vote together
          as a class on such resolution or action of the Manager (but not
          any other resolution or action) and such amendment or action
          shall not be effective except with the approval of the Preferred
          Members holding at least a Majority in Liquidation Preference of
          such outstanding securities including, if applicable the holders
          of either or both of the Company Dividend Parity Securities and
          the Company Liquidation Party Securities, as the case may be;
          provided, however, that no such approval shall be required if (1)
          --------  -------
          the liquidation, dissolution or winding-up of the Company is
          proposed or initiated upon the occurrence of any of the events
          specified in Section 15.2 (except Section 15.2(c)) or (2) this
          Agreement is amended pursuant to Section 16.1.

                    The Manager shall not, without the approval of the
          holders of at least a Majority in Liquidation Preference of the
          Preferred Securities, vote such ICG Preferred Stock with respect
          to proposed actions that would have an adverse effect on the
          specific rights, preferences, privileges or voting rights of the
          Company with respect to the ICG Preferred Stock, or cause the
          dissolution, winding-up or termination of the Company. 
          Notwithstanding any other provision of this Agreement to the
          contrary, the Preferred Members shall be entitled to vote in
          connection with any solicitation by the Manager for the consent
          of the Preferred Members to the voting by the Manager of the
          Company's ICG Preferred Stock.  The powers, preferences or
          special rights of the Preferred Securities of any series will be
          deemed not to be adversely affected by the creation or issuance
          of, and no vote will be required for the creation or issuance of,
          any further Interests in the Company ranking junior to or pari
          passu with the Preferred Securities of such series with respect
          to voting rights or rights to payment of dividends or
          distribution of assets upon liquidation, dissolution or
          winding-up of the Company.

                    (c)  Notwithstanding any provision to the contrary
          herein, the first sentence of Section 14.1 of this Agreement may
          only be amended with the consent of each Preferred Member;
          provided that, to the fullest extent permitted by applicable law,
          any such amendment shall not permit the Preferred Members to
          approve any transferee of Common Securities.

                    (d)  Notwithstanding that Preferred Members holding
          Preferred Securities of any series are entitled to vote or
          consent under any of the circumstances described in this
          Agreement, any of the Preferred Securities of any series that are
          owned by ICG or by any entity more than 50% of which is owned by
          ICG, either directly or indirectly, shall not be entitled to vote
          or consent and shall, for the purposes of such vote or consent,
          be treated as if they were not outstanding.

               SECTION 8.2.  VOTING RIGHTS OF HOLDER OF COMMON SECURITIES. 
          Except as otherwise provided herein or in the Preferred
          Securities Designation for any series of Preferred Securities and
          except as otherwise required by the Delaware Act, all voting
          rights of the Company shall be vested exclusively in the Common
          Member. The Common Securities shall entitle the Common Member to
          vote upon all matters upon which the Common Member has the right
          to vote.  The Common Member shall have the right to vote
          separately as a class on any matter on which the Common Member
          has the right to vote regardless of the voting rights of any
          other Member.

               SECTION 8.3.  MEETINGS OF THE MEMBERS.

                    (a)  Meetings of the Members of any class or series or
          of all classes or series of Interests may be called at any time
          by the Manager or as provided by any applicable Preferred
          Securities Designation. Except to the extent otherwise provided,
          the following provisions shall apply to meetings of Members.

                    (b)  Members may vote in person or by proxy at such
          meeting. Whenever a vote, consent or approval of Members is
          permitted or required under this Agreement or any applicable
          Preferred Securities Designation, such vote, consent or approval
          may be given at a meeting of Members or by written consent.

                    (c)  Each Member may authorize any Person to act for it
          by proxy on all matters in which a Member is entitled to vote,
          including waiving notice of any meeting, or voting or
          participating at a meeting. Every proxy must be signed by the
          Member or its attorney-in-fact and shall be revocable at the
          pleasure of the Member executing it at any time before it is
          voted.

                    (d)  Each meeting of Members shall be conducted by the
          Manager or by such other Person that the Manager may designate.

                    (e)  Any required approval of Preferred Members holding
          Preferred Securities of a series may be given at a separate
          meeting of such Preferred Members convened for such purpose or at
          a meeting of Members of the Company or pursuant to written
          consents. The Manager will cause a notice of any meeting at which
          Preferred Members holding Preferred Securities of a series are
          entitled to vote, or of any matter upon which action by written
          consent of such Preferred Members is to be taken, to be mailed to
          each Preferred Member holding Preferred Securities of such
          series. Each such notice will include a statement setting forth
          (i) the date of such meeting or the date by which such action is
          to be taken, (ii) a description of any matter on which such
          Preferred Members are entitled to vote or of such matter upon
          which written consent is sought and (iii) instructions for the
          delivery of proxies or consents.

                    (f)  Subject to Section 8.3(e) and the applicable
          Preferred Securities Designation, the Manager, in its sole
          discretion, shall establish all other provisions relating to
          meetings of Members, including notice of the time, place or
          purpose of any meeting at which any matter is to be voted on by
          any Members, waiver of any such notice, action by consent without
          a meeting, the establishment of a record date, quorum
          requirements (but in no event higher than a Majority in
          Liquidation Preference of the Preferred Securities of any
          series), voting in person or by proxy or any other matter with
          respect to the exercise of any such right to vote.

                                      ARTICLE IX
                                      DIVIDENDS

               SECTION 9.1.  DIVIDENDS.

                    (a) Preferred Members shall receive periodic dividends,
          if any, in accordance with the Preferred Securities Designation
          for the Preferred Securities of any particular series, as and
          when declared by the Manager, and the Common Member shall receive
          periodic dividends, subject to Section 9.3 of this Agreement, the
          applicable terms of any series of Preferred Securities and the
          provisions of the Delaware Act, as and when declared by the
          Manager, in its discretion out of funds of the Company legally
          available therefor.

                    (b)  Dividends on the Preferred Securities shall be
          declared by the Manager to the extent that the Manager reasonably
          anticipates that at the time of payment the Company will have,
          and must be paid by the Company to the extent that at the time of
          proposed payment it has funds legally available for the payment
          of such dividends.

                    (c)  A Preferred Member shall not be entitled to
          receive any dividend with respect to the Preferred Securities of
          any series, irrespective of whether such dividend has been
          declared by the Manager, prior to the date on which such dividend
          is payable as set forth in the Preferred Securities Designation
          (the "Dividend Payment Date") and until such time as the Company
          has received the dividend payment on the ICG Preferred Stock of
          the related series for the dividend payment date corresponding to
          such Divided Payment Date and such monies are available for
          distribution to the Preferred Member pursuant to the terms of
          this Agreement and the Delaware Act.

               SECTION 9.2.  LIMITATIONS ON DISTRIBUTIONS. Notwithstanding
          any provision to the contrary contained in this Agreement, the
          Company shall not make a distribution (including a dividend) to
          any Member on account of its Interest if such distribution would
          violate Section 18-607 or 18-804 of the Delaware Act or other
          applicable law.

               SECTION 9.3.  CERTAIN RESTRICTIONS ON THE PAYMENT OF
          DIVIDENDS. If accumulated dividends have not been paid in full on
          the Preferred Securities of any series then outstanding, the
          Company shall not:

                    (i)  pay, or declare and set aside for payment, any
               dividends on the Preferred Securities of any other series or
               any other Interests in the Company ranking pari passu with
               the Preferred Securities of such series as to the payment of
               dividends ("Company Dividend Parity Securities"), unless the
               amount of any dividends declared on such Company Dividend
               Parity Securities is paid on such Company Dividend Parity
               Securities and the Preferred Securities of such series on a
               pro rata basis on the date such dividends are paid on such
               Company Dividend Parity Securities, so that the ratio of

                         (x)  (A)  the aggregate amount paid as dividends
                    on the Preferred Securities of such series to (B) the
                    aggregate amount paid as dividends on the Company
                    Dividend Parity Securities is the same as the ratio of

                         (y)  (A)  the aggregate amount of all accumulated
                    arrears of unpaid dividends on the Preferred Securities
                    of such series to (B) the aggregate amount of all
                    accumulated arrears of unpaid dividends on the Company
                    Dividend Parity Securities;

                    (ii) pay, or declare and set aside for payment, any
               dividends on any Interests in the Company ranking junior to
               the Preferred Securities of such series as to the payment of
               dividends ("Company Dividend Junior Securities"); or

                    (iii)     redeem, purchase or otherwise acquire any
               Company Dividend Parity Securities or Company Dividend
               Junior Securities (other than purchases or acquisitions
               resulting from the reclassification of such Securities or
               the exchange or conversion of any Company Dividend Parity
               Security or Company Dividend Junior Security pursuant to the
               terms thereof or the purchase of fractional interests
               therein upon such conversion or exchange);

               until, in each case, such time as all accumulated and unpaid
               dividends on all of the Preferred Securities of such series
               shall have been paid in full or have been irrevocably set
               aside for payment in full for all dividend periods
               terminating on or prior to, in the case of clauses (i) and
               (ii), the date of such payment, and in the case of clause
               (iii), the date of such redemption, purchase or other
               acquisition.

          shall keep or cause to be kept at the address of the Manager (or

               SECTION 10.3.  LIMITATION ON ACCESS TO RECORDS.
          Notwithstanding any provision of this Agreement, the Manager may,
          to the maximum extent permitted by law, keep confidential from
          the Preferred Members any information the disclosure of which the
          Manager reasonably believes is not in the best interest of the
          Company or could damage the Company or its business or which the
          Company or the Manager is required by law or by an agreement with
          any Person to keep confidential.

                                      ARTICLE XI

               SECTION 11.1.  COMPANY TAX RETURNS.

                    (a) The Manager shall cause to be prepared and timely
          filed all tax returns required to be filed for the Company. The
          Manager may, in its discretion, make or refrain from making any
          federal, state or local income or other tax elections for the
          Company that it deems necessary or advisable, including, without
          limitation, any election under Section 754 of the Code or any
          successor provision.

                    (b)  The Manager is hereby designated as the Company's
          "Tax Matters Partner" under Code Section 6231(a)(7) and shall
          have all the powers and responsibilities of such position as
          provided in the Code. The Manager is specifically directed and
          authorized to take whatever steps the Manager, in its discretion,
          deems necessary or desirable to perfect such designation,
          including filing any forms or documents with the Internal Revenue
          Service and taking such other action as may from time to time be
          required under the regulations issued under the Code. Expenses

          will be borne by the Company.

               SECTION 11.2.  TAX REPORTS. The Manager shall, as promptly
          as practicable and in any event within 90 days after the end of

          as will preserve its treatment as a partnership for U.S. federal
          income tax purposes.

               SECTION 11.4  INVESTMENT PARTNERSHIP.  The Manager shall
          cause the Company not to "engage in a trade or business" or make
          any investments or take any action that would cause the Company
          to fail to qualify as an "investment partnership" as such term is
          defined in Section 731(c)(3)(C) of the Code.

          Company shall be responsible for and shall pay all expenses out
          of funds of the Company determined by the Manager to be available
          for such purpose, provided that such expenses or obligations are
          those of the Company or are otherwise incurred by the Manager in
          connection with this Agreement, including, without limitation:

               liquidation, dissolution or winding-up of the Company.

                                     ARTICLE XIII
                                      LIABILITY

               SECTION 13.1.  LIABILITY OF COMMON MEMBER.  The Common
          Member, by acquiring its Interest and being admitted to the
          Company as the Common Member, shall be liable to the creditors of
          the Company (other than to Members holding other classes or
          series of Interests, in their capacity as Members) (hereinafter
          referred to individually as a "Third Party Creditor," and
          collectively as the "Third Party Creditors") to the same extent
          that a general partner of a limited partnership formed under the
          LP Act is liable under Section 17-403(b) of the LP Act to
          creditors of the limited partnership (other than the other
          partners in their capacity as partners), as if the Company were a
          limited partnership formed under the LP Act and the Common Member
          was a general partner of the limited partnership. In furtherance
          but not in limitation of the generality of the foregoing, the
          Common Member is liable for any and all debts, obligations and
          other liabilities of the Company, whether arising under contract
          or by tort, statute, operation of law or otherwise, all of which
          shall be enforceable directly and absolutely against the Common
          Member by each Third Party Creditor.

               SECTION 13.2.  LIABILITY OF PREFERRED MEMBERS.

                    (a)  Except as otherwise provided by the Delaware Act,
               (i) the debts, obligations and liabilities of the Company,
               whether arising by contract, tort, statute, operation of law
               or otherwise, shall be solely the debts, obligations and
               liabilities of the Company and, to the extent set forth in
               Section 13.1 of this Agreement, the Common Member and (ii)
               no Preferred Member shall be obligated personally for any
               such debt, obligation or liability of the Company solely by
               reason of being a Preferred Member of the Company.

                    (b)  A Preferred Member, in its capacity as such, shall
               have no liability in excess of (i) the amount of its capital
               contributions, (ii) its share of any assets and
               undistributed profits of the Company, (iii) any amounts
               required to be paid by such Preferred Member in the
               Preferred Securities Designation for the series of Preferred
               Securities held by such Preferred Member and (iv) the amount
               of any distributions wrongfully distributed to the extent
               required by Section 18-607 of the Delaware Act or other
               applicable law.

                                     ARTICLE XIV
                               ASSIGNMENT OF INTERESTS

               SECTION 14.1.  ASSIGNMENT OF INTERESTS. Notwithstanding
          anything to the contrary in this Agreement, after the date hereof
          Common Securities shall be non-assignable and non-transferable
          (other than pursuant to a merger or consolidation of the Common
          Member), and may only be issued to and held by ICG or its
          successor.  Preferred Securities shall be freely assignable and
          transferable, subject to the provisions of Section 2.7 of this
          Agreement.

               SECTION 14.2.  RIGHT OF ASSIGNEE TO BECOME A MEMBER. An
          assignee of a Preferred Security shall become a Preferred Member
          upon compliance with the provisions of Section 2.7 of this
          Agreement.

               SECTION 14.3.  EVENTS OF CESSATION OF MEMBERSHIP. A Person
          shall cease to be a Member upon (i) the assignment of its
          Interests in accordance with this Agreement, such assignment to
          be effective immediately after the admission of its transferee,
          (ii) any redemption, exchange or other repurchase by the Company
          or the Common Member; or (iii) as otherwise provided herein.

                                      ARTICLE XV
                       DISSOLUTION, LIQUIDATION AND TERMINATION

               SECTION 15.1.  NO DISSOLUTION. The Company shall not be
          dissolved by the admission of Members in accordance with the
          terms of this Agreement. Except as provided in Sections 15.2(b)
          of this Agreement, the death, retirement, resignation, expulsion,
          bankruptcy or dissolution of a Member, or the occurrence of any
          other event which terminates the continued membership of a Member
          in the Company, shall not cause the Company to be dissolved and
          its affairs wound up so long as the Company at all times has at
          least two Members. Upon the occurrence of any such event, the
          business of the Company shall be continued without dissolution.

               SECTION 15.2.  EVENTS CAUSING DISSOLUTION. The Company shall
          be dissolved and its affairs shall be wound up upon the earliest
          to occur of any of the following events:

                    (a)  the expiration of the term of the Company, as
               provided in Section 2.3 of this Agreement;

                    (b)  the dissolution, winding-up or liquidation of the
               Common Member or the occurrence of any other event that
               terminates the continued membership of the Common Member
               under the Delaware Act; 

                    (c)  the decision made by the Manager (subject to the
               voting rights of Preferred Members set forth in Section 8.1
               of this Agreement) to dissolve the Company;

                    (d)  the entry of a decree of judicial dissolution of
               the Company under Section 18-802 of the Delaware Act;

                    (e)  the election of the Manager, in connection with
               the exchange of all series of Preferred Securities
               outstanding (in accordance with the Preferred Securities
               Designation for such series of Preferred Securities) for the
               ICG Common Stock or the redemption of all series of
               Preferred Securities outstanding (in accordance with the
               Preferred Securities Designation for such series of
               Preferred Securities); or

                    (f)  the written consent of all Members.

               SECTION 15.3.  NOTICE OF DISSOLUTION. Upon the dissolution
          of the Company, the Manager shall promptly notify the Members of
          such dissolution.

               SECTION 15.4.  LIQUIDATION. Upon dissolution of the Company,
          the Manager or, in the event that the dissolution is caused by an
          event described in Section 15.2(b) or (c) and there is no
          Manager, a Person or Persons who may be approved by the Preferred
          Members holding a Majority in Liquidation Preference of the
          Preferred Securities, as liquidating trustees, shall immediately
          commence to wind-up the Company's affairs; provided, however,
          that a reasonable time shall be allowed for the orderly
          liquidation of the assets of the Company and the satisfaction of
          liabilities to creditors so as to enable the Members to minimize
          the normal losses attendant upon a liquidation. The proceeds of
          liquidation shall be distributed, as realized, in the manner
          provided in Section 18-804 of the Delaware Act, subject (after
          compliance with Section 18.804(a)(i) of the Delaware Act) to the
          Preferred Securities Designation for any series of Preferred
          Securities and Section 15.5 of this Agreement.

               SECTION 15.5.  CERTAIN RESTRICTIONS ON LIQUIDATION PAYMENTS.
          In the event of any voluntary or involuntary liquidation,
          dissolution or winding-up of the Company other than in connection
          with the exchange of all series of Preferred Securities
          outstanding (in accordance with the Preferred Securities
          Designation for each such series of Preferred Securities) for the
          ICG Common Stock, Preferred Members holding Preferred Securities
          of each series at the time outstanding will be entitled to
          receive out of the assets of the Company legally available for
          distribution to Members, before any distribution of assets is
          made to the Common Member or Members holding any other class of
          Interests in the Company ranking junior to the Preferred
          Securities of such series as to the distribution of assets upon
          liquidation, dissolution or winding-up of the Company, but
          together with Preferred Members holding Preferred Securities of
          any other series or any other Interests in the Company then
          outstanding ranking pari passu with the Preferred Securities of
          such series as to the distribution of assets upon liquidation,
          dissolution or winding-up of the Company ("Company Liquidation
          Parity Securities"), an amount equal to the aggregate liquidation
          preference for Preferred Securities of such series as set forth
          in the applicable Preferred Securities Designation plus all
          accumulated and unpaid dividends (whether or not earned or
          declared), to the date of payment (the "Liquidation
          Distribution"). If, upon any such liquidation, dissolution or
          winding-up, the Liquidation Distributions can be paid only in
          part because the Company has insufficient assets available to pay
          in full the aggregate Liquidation Distributions and the aggregate
          maximum liquidation distributions on the Company Liquidation
          Parity Securities, then the amounts payable by the Company on the
          Preferred Securities of such series and on such Company
          Liquidation Parity Securities shall be paid on a pro rata basis,
          so that the ratio of

                    (i)  (x)  the aggregate amount paid as Liquidation
               Distributions on the Preferred Securities of such series to
               (y) the aggregate amount paid as Liquidation Distributions
               on the Company Liquidation Parity Securities, is the same as
               the ratio of

                    (ii) (x)  the aggregate Liquidation Distributions on
               the Preferred Securities of such series to (y) the aggregate
               maximum Liquidation Distributions on the Company Liquidation
               Parity Securities.

               SECTION 15.6.  TERMINATION. The Company shall terminate when
          all of the assets of the Company have been distributed in the
          manner provided for in this Article XV, and the Certificate shall
          have been cancelled in the manner required by the Delaware Act.

                                     ARTICLE XVI
                                    MISCELLANEOUS

               SECTION 16.1.  AMENDMENTS. Except as otherwise provided in
          this Agreement, this Agreement may be amended by a written
          instrument executed by the Common Member if, in the opinion of
          independent counsel, such amendment does not materially adversely
          affect the rights, powers and preferences of the Preferred
          Members; if, however, in the opinion of such counsel, such
          amendment would materially adversely affect the rights, powers
          and preferences of the Preferred Members, such amendment shall
          require the consent of the Majority in Liquidation Preference of
          such Preferred Members.  

               SECTION 16.2.  SUCCESSORS; COUNTERPARTS. This Agreement (a)
          shall be binding as to the executors, administrators, estates,
          heirs and legal successors, or nominees or representatives, of
          the Members and (b) may be executed in several counterparts with
          the same effect as if the parties executing the several
          counterparts had all executed one counterpart. No person other
          than the Members and their respective executors, administrators,
          estates, heirs and legal successors, or their nominees or
          representatives, shall obtain any rights by virtue of this
          Agreement.

               SECTION 16.3.  GOVERNING LAW; SEVERABILITY. This Agreement
          shall be governed by and construed in accordance with the laws of
          the State of Delaware.  In particular, this Agreement shall be
          construed to the maximum extent possible to comply with all of
          the terms and conditions of the Delaware Act. If, nevertheless,
          it shall be determined by a court of competent jurisdiction that
          any provisions or wording of this Agreement shall be invalid or
          unenforceable under the Delaware Act or other applicable law,
          such invalidity or unenforceability shall not invalidate the
          entire Agreement. In that case, this Agreement shall be construed
          so as to limit any term or provision so as to make it enforceable
          or valid within the requirements of applicable law, and, in the
          event such term or provisions cannot be so limited, this
          Agreement shall be construed to omit such invalid or
          unenforceable provisions. If it shall be determined by a court of
          competent jurisdiction that any provision relating to the
          distributions and allocations of the Company or to any fee
          payable by the Company is invalid or unenforceable, this
          Agreement shall be construed or interpreted so as (a) to make it
          enforceable or valid and (b) to make the distributions and
          allocations as closely equivalent to those set forth in this
          Agreement as is permissible under applicable law.

               SECTION 16.4.  FILINGS.  Following the execution and
          delivery of this Agreement, the Manager shall promptly prepare
          any documents required to be filed and recorded under the
          Delaware Act, and the Manager shall promptly cause each such
          document to be filed and recorded in accordance with the Delaware
          Act and, to the extent required by local law, to be filed and
          recorded or notice thereof to be published in the appropriate
          place in each jurisdiction in which the Company may hereafter
          establish a place of business. The Manager shall also promptly
          cause to be filed, recorded and published such statements or
          other instruments required by any provision of any applicable law
          of the United States or any state or other jurisdiction which
          governs the conduct of its business from time to time.

               SECTION 16.5.  POWER OF ATTORNEY. Each Preferred Member does
          hereby constitute and appoint the Manager as its true and lawful
          representative and attorney-in-fact, in its name, place and stead
          to make, execute, sign, deliver and file (a) any amendment of the
          Certificate required because of an amendment to this Agreement or
          in order to effectuate any change in the membership of the
          Company, (b) any amendment to this Agreement made in accordance
          with the terms hereof and (c) all such other instruments,
          documents and certificates which may from time to time be
          required by the laws of the United States of America, the State
          of Delaware or any other jurisdiction, or any political
          subdivision of agency thereof, to effectuate, implement and
          continue the valid and subsisting existence of the Company or to
          dissolve the Company or for any other purpose consistent with
          this Agreement and the transactions contemplated hereby.

               The power of attorney granted hereby is coupled with an
          interest and shall (a) survive and not be affected by the
          subsequent death, incapacity, disability, dissolution,
          termination or bankruptcy of the Preferred Member granting the
          same or the transfer of all or any portion of such Preferred
          Member's Interest and (b) extend to such Preferred Member's
          successors, assigns and legal representatives.

               SECTION 16.6.  EXCULPATION.

                    (a)  No Covered Person shall be liable to the Company
          or any Member for any loss, damage or claim incurred by reason of
          any act or omission performed or omitted by such Covered Person
          in good faith on behalf of the Company and in a manner reasonably
          believed to be within the scope of authority conferred on such
          Covered Person by this Agreement.

               (b)  A Covered Person shall be fully protected in relying in
          good faith upon the records of the Company and upon such
          information, opinions, reports or statements presented to the
          Company by any Person as to matters the Covered Person reasonably
          believes are within such other Person's professional or expert
          competence and who has been selected with reasonable care by or
          on behalf of the Company, including information, opinions,
          reports or statements as to the value and amount of the assets,
          liabilities, profits, losses, or any other facts pertinent to the
          existence and amount of assets from which distributions to
          Members might properly be paid.

               SECTION 16.7.  INDEMNIFICATION. To the fullest extent
          permitted by applicable law, an Indemnified Person shall be
          entitled to indemnification from the Company for any loss, damage
          or claim incurred by such Indemnified Person by reason of any act
          or omission performed or omitted by such Indemnified Person in
          good faith on behalf of the Company and in a manner reasonably
          believed to be within the scope of authority conferred on such
          Indemnified Person by this Agreement; provided, however, that any
          indemnity under this Section 16.7 shall be provided out of and to
          the extent of Company assets only, and no Member shall have any
          personal liability on account thereof. The right of
          indemnification pursuant to this Section 16.7 shall include the
          right to be paid, in advance, or reimbursed by the Company for
          the reasonable expenses incurred by an Indemnified Person who
          was, is, or is threatened to be made a named defendant or
          respondent in a proceeding.

               SECTION 16.8.  ADDITIONAL DOCUMENTS. Each Preferred Member,
          upon the request of the Manager, agrees to perform all further
          acts and execute, acknowledge and deliver any documents that may
          be reasonably necessary to carry out the provisions of this
          Agreement.

               SECTION 16.9.  NOTICES. All notices provided for in this
          Agreement shall be in writing, duly signed by the party giving
          such notice, and shall be delivered, telecopied or mailed by

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

                    (a)  Funding and ICG shall, within 90 days following
          the Closing Date, file with the SEC a Shelf Registration
          Statement relating to the offer and sale of the Registrable
          Securities by the Holders from time to time in accordance with
          the methods of distribution elected by such Holders and set forth

          days following the Closing Date.  Each of ICG and Funding agrees
          to use its best efforts to keep the Shelf Registration Statement
          continuously effective until November 15, 2009 (or, if, in the
          written opinion, satisfactory in form and substance to the

          without registration under the 1933 Act pursuant to Rule 144(k)
          under the 1933 Act or any successor provision thereof, then until
          such earlier date) or such shorter period that will terminate
          when all of the Registrable Securities covered by the Shelf
          Registration Statement have been sold pursuant to a Shelf
          Registration Statement.  ICG and Funding further agree to
          supplement or amend the Shelf Registration Statement if required
          by the rules, regulations or instructions applicable to the
          registration form used by ICG and Funding for such Shelf
          Registration Statement or by the 1933 Act or by any other rules
          and regulations thereunder for shelf registration or if
          reasonably requested by a Holder with respect to information
          relating to such Holder, and to use its best efforts to cause any
          such amendment to become effective and such Shelf Registration
          Statement to become usable as soon as thereafter practicable. 
          ICG and Funding agree to furnish to the Holders of Registrable
          Securities copies of any such supplement or amendment promptly
          after its being used or filed with the SEC.

                    (b)  ICG shall pay all Registration Expenses in
          connection with the registration pursuant to Section 2(a).  Each
          Holder shall pay all underwriting discounts and commissions and
          transfer taxes, if any, relating to the sale or disposition of
          such Holder's Registrable Securities pursuant to the Shelf
          Registration Statement.

                    (c)  A Shelf Registration Statement pursuant to Section
          2(a) hereof will not be deemed to have become effective unless it
          has been declared effective by the SEC; provided, however, that,
                                                  --------  -------
          if, after it has been declared effective, the offering of
          Registrable Securities pursuant to a Shelf Registration Statement
          is interfered with by any stop order, injunction or other order
          or requirement of the SEC or any other governmental agency or
          court, such Shelf Registration Statement will be deemed not to
          have become effective during the period of such interference
          until the offering of Registrable Securities pursuant to such
          Shelf Registration Statement may legally resume.  As provided in
          the LLC Agreement, if on or prior to the 90th day following the
          Closing Date, the Shelf Registration Statement has not been
          filed, dividends payable on the Preferred Securities (in addition
          to the dividends otherwise payable on the Preferred Securities)
          will accrue at an annual rate of 0.25% of the liquidation
          preference thereof until the Shelf Registration Statement is
          filed, and if on or prior to the 180th day following the Closing
          Date, the Shelf Registration Statement is not declared effective,
          dividends payable on the Preferred Securities (in addition to the
          dividends otherwise payable on the Preferred Securities) will
          accrue at an additional annual rate of 0.25% of the liquidation
          preference thereof until the Shelf Registration Statement is
          declared effective, in each case payable in (i) cash, (ii) shares
          of ICG Common Stock, valued at 90% of the Average Market Value of
          the ICG Common Stock, or (iii) any combination of cash or ICG
          Common Stock (provided that such payment must be made in cash to
          the extent ICG shall have provided Funding with cash to make all
          or any portion of such payment).

                    (d)  Without limiting the remedies available to the
          Placement Agents and the Holders, ICG and Funding acknowledge
          that any failure by ICG and Funding to comply with their
          respective obligations under Section 2(a) hereof may result in
          material irreparable injury to the Placement Agents or the
          Holders for which there is no adequate remedy at law, that it
          will not be possible to measure damages for such injuries
          precisely and that, in the event of any such failure, the
          Placement Agents or any Holder may obtain such relief as may be
          required to specifically enforce ICG's and Funding's obligations
          under Section 2(a) hereof.

                    3.   Registration Procedures.
                         -----------------------

                    In connection with the obligations of ICG and Funding
          with respect to the Shelf Registration Statements pursuant to
          Section 2(a) hereof, ICG and Funding shall as expeditiously as
          possible:

                    (a)  prepare and file with the SEC a Shelf Registration
               Statement on the appropriate form under the 1933 Act, which
               form (x) shall be selected by ICG and Funding and (y) shall
               be available for the sale of the Registrable Securities by
               the selling Holders thereof and (z) shall comply as to form
               in all material respects with the requirements of the
               applicable form and include all financial statements
               required by the SEC to be filed therewith, and use their

               other acts and things which may be reasonably necessary or
               advisable to enable such Holder to consummate the
               disposition in each such jurisdiction of such Registrable
               Securities owned by such Holder; provided, however, that

               any material respect or which requires the making of any
               changes in such Shelf Registration Statement or Prospectus

               reasonably request at least two business days prior to the
               closing of any sale of Registrable Securities;

                    (i)  upon the occurrence of any event contemplated by
               Section 3(e)(v) hereof, use their best efforts to prepare
               and file with the SEC a supplement or post-effective
               amendment to a Shelf Registration Statement or the related
               Prospectus or any document incorporated therein by reference
               or file any other required document so that, as thereafter
               delivered to the purchasers of the Registrable Securities,

               material fact or omit to state a material fact necessary to
               make the statements therein, in light of the circumstances
               under which they were made, not misleading.  ICG and Funding

               event, and the Holders hereby agree to suspend use of the
               Prospectus until ICG and Funding have amended or
               supplemented the Prospectus to correct such misstatement or
               omission;

               any Shelf Registration Statement, any Prospectus, any
               amendment to a Shelf Registration Statement or amendment or
               supplement to a Prospectus or any document which is to be
               incorporated by reference into a Shelf Registration
               Statement or a Prospectus after initial filing of a Shelf
               Registration Statement, provide copies of such document to
               the Placement Agents and their counsel and the Holders and
               their counsel and make such representatives of ICG or
               Funding as shall be reasonably requested by the Placement
               Agents or their counsel and the Holders or their counsel,
               available for discussion of such document, and shall not at

               Statement, any Prospectus or any amendment of or supplement
               to a Shelf Registration Statement or a Prospectus or any
               document which is to be incorporated by reference into a

               counsel shall not have previously been advised and furnished
               a copy or to which the Placement Agents or their counsel and
               the Holders or their counsel shall object, except for any
               amendment or supplement or document (a copy of which has
               been previously furnished to the Placement Agents and their
               counsel and the Holders and their counsel) which counsel to
               ICG and Funding shall advise ICG and Funding, in the form of
               a written legal opinion, is required in order to comply with
               applicable law;

               Securities not later than the effective date of a Shelf
               Registration Statement;

               reasonable manner, all financial and other records,
               pertinent documents and properties of ICG and Funding, and
               cause the respective officers, directors and employees of

               or accountant in connection with a Shelf Registration
               Statement;

                    (m)  use their best efforts to cause all shares of ICG
               Common Stock issuable upon exchange of or payable as
               dividends on the Preferred Securities to be listed on the

               issued by ICG or Funding are then listed if requested by the
               Majority Holders, to the extent such Preferred Securities
               satisfy applicable listing requirements;

                    (o)  if reasonably requested by any Holder of
               Registrable Securities covered by a Shelf Registration
               Statement, (i) promptly incorporate in a Prospectus
               supplement or post-effective amendment such information with
               respect to such Holder as such Holder reasonably requests to
               be included therein and (ii) make all required filings of
               such Prospectus supplement or such post-effective amendment
               as soon as ICG and Funding have received notification of the
               matters to be incorporated in such filing; and

                    (p)  enter into such customary agreements and take all
               such other actions in connection therewith (including those
               requested by the Holders of a majority of the Registrable
               Securities being sold) in order to expedite or facilitate
               the disposition of such Registrable Securities including,
               but not limited to, an Underwritten Offering and in such
               connection, (i) to the extent possible, make such
               representations and warranties to the Holders and any
               Underwriters of such Registrable Securities with respect to
               the business of ICG and Funding and their subsidiaries, the
               Shelf Registration Statement, Prospectus and documents
               incorporated by reference or deemed incorporated by
               reference, if any, in each case in form, substance and scope
               as are customarily made by issuers to underwriters in
               underwritten offerings and confirm the same if and when
               requested, (ii) obtain opinions of counsel to ICG and
               Funding (which counsel and opinions, in form, scope and

               and such Underwriters and their respective counsel)
               addressed to each selling Holder and Underwriter of
               Registrable Securities, covering the matters customarily
               covered in opinions requested in underwritten offerings,
               (iii) obtain "cold comfort" letters from the independent
               certified public accountants of ICG and Funding (and, if
               applicable, any other certified public accountant of any
               subsidiary of ICG and Funding, or of any business acquired
               by ICG or Funding for which financial statements and
               financial data are or are required to be included in the
               Shelf Registration Statement) addressed to each selling
               Holder and Underwriter of Registrable Securities, such
               letters to be in customary form and covering matters of the
               type customarily covered in "cold comfort" letters in
               connection with underwritten offerings, and (iv) deliver
               such documents and certificates as may be reasonably
               requested by the Holders of a majority of the Registrable
               Securities being sold or the Underwriters, and which are
               customarily delivered in underwritten offerings, to evidence
               the continued validity of the representations and warranties
               of ICG and Funding made pursuant to clause (i) above and to
               evidence compliance with any customary conditions contained
               in an underwriting agreement. 

                    ICG and Funding may require each Holder of Registrable
          Securities to furnish to ICG and Funding such information
          regarding the Holder and the proposed distribution by such Holder
          of such Registrable Securities as ICG and Funding may from time
          to time reasonably request in writing.  

                    Each Holder agrees that, upon receipt of any notice
          from ICG and Funding of the happening of any event of the kind
          described in Section 3(e)(v) hereof, such Holder will forthwith
          discontinue disposition of Registrable Securities pursuant to a
          Shelf Registration Statement until such Holder's receipt of the
          copies of the supplemented or amended Prospectus contemplated by
          Section 3(i) hereof, and, if so directed by ICG and Funding, such
          Holder will deliver to ICG and Funding (at its expense) all
          copies in its possession, other than permanent file copies then
          in such Holder's possession, of the Prospectus covering such
          Registrable Securities current at the time of receipt of such
          notice.  If ICG and Funding shall give any such notice to suspend
          the disposition of Registrable Securities pursuant to a Shelf
          Registration Statement, ICG and Funding shall extend the period
          during which such Shelf Registration Statement shall be
          maintained effective pursuant to this Agreement by the number of
          days during the period from and including the date of the giving
          of such notice to and including the date when the Holders shall
          have received copies of the supplemented or amended Prospectus
          necessary to resume such dispositions.

                    The Holders of Registrable Securities covered by a
          Shelf Registration Statement who desire to do so may sell such
          Registrable Securities in an Underwritten Offering.  In any such
          Underwritten Offering, the investment banker or investment
          bankers and manager or managers (the "Underwriters") that will
          administer the offering will be selected by the Majority Holders
          of the Registrable Securities included in such offering.

                    4.   Indemnification and Contribution.
                         --------------------------------

                    (a)  Each of Funding and ICG, jointly and severally,
          agrees to indemnify and hold harmless each Placement Agent, each
          Holder and each person, if any, who controls any Placement Agent
          or any Holder within the meaning of either Section 15 of the 1933
          Act or Section 20 of the 1934 Act, or is under common control
          with, or is controlled by, any Placement Agent or any Holder,
          from and against all losses, claims, damages and liabilities
          (including, without limitation, any legal or other expenses
          reasonably incurred by any Placement Agent, any Holder or any
          such controlling or affiliated Person in connection with
          defending or investigating any such action or claim) caused by
          any untrue statement or alleged untrue statement of a material
          fact contained in any Shelf Registration Statement (or any
          amendment thereto) pursuant to which Registrable Securities were
          registered under the 1933 Act, including all documents
          incorporated therein by reference, or caused by any omission or
          alleged omission to state therein a material fact required to be
          stated therein or necessary to make the statements therein not
          misleading, or caused by any untrue statement or alleged untrue
          statement of a material fact contained in any Prospectus (as
          amended or supplemented if ICG and Funding shall have furnished
          any amendments or supplements thereto), or caused by any omission
          or alleged omission to state therein a material fact necessary to
          make the statements therein in light of the circumstances under
          which they were made not misleading, except insofar as such
          losses, claims, damages or liabilities are caused by any such
          untrue statement or omission or alleged untrue statement or
          omission based upon information relating to any Placement Agent
          or any Holder furnished to ICG and Funding in writing by any
          Placement Agent through Morgan Stanley or any selling Holder
          expressly for use therein.  In connection with any Underwritten
          Offering permitted by Section 3 of this Agreement, each of ICG
          and Funding, jointly and severally, will also indemnify the
          Underwriters, if any, selling brokers, dealers and similar
          securities industry professionals participating in the
          distribution, their officers and directors and each Person who
          controls such Persons (within the meaning of the 1933 Act and the
          1934 Act) to the same extent as provided above with respect to
          the indemnification of the Holders, if requested in connection
          with a Shelf Registration Statement.

                    (b)  Each Holder agrees, severally and not jointly, to
          indemnify and hold harmless ICG, Funding, each Placement Agent
          and the other selling Holders, and each of their respective
          directors, officers who sign a Shelf Registration Statement and
          each Person, if any, who controls ICG or Funding, any Placement
          Agent and any other selling Holder within the meaning of either
          Section 15 of the 1933 Act or Section 20 of the 1934 Act to the
          same extent as the foregoing indemnity from ICG and Funding to
          the Placement Agents and the Holders, but only with reference to
          information relating to such Holder furnished to ICG and Funding
          in writing by such Holder expressly for use in a Shelf
          Registration Statement (or any amendment thereto) or any
          Prospectus (or any amendment or supplement thereto).

                    (c)  In case any proceeding (including any governmental
          investigation) shall be instituted involving any Person in
          respect of which indemnity may be sought pursuant to either
          paragraph (a) or paragraph (b) above, such Person (the
          "indemnified party") shall promptly notify the Person against
          whom such indemnity may be sought (the "indemnifying party") in
          writing and the indemnifying party, upon request of the
          indemnified party, shall retain counsel reasonably satisfactory
          to the indemnified party to represent the indemnified party and
          any others the indemnifying party may designate in such
          proceeding and shall pay the fees and disbursements of such
          counsel related to such proceeding.  In any such proceeding, any
          indemnified party shall have the right to retain its own counsel,
          but the fees and expenses of such counsel shall be at the expense
          of such indemnified party unless (i) the indemnifying party and
          the indemnified party shall have mutually agreed to the retention
          of such counsel or (ii) the named parties to any such proceeding
          (including any impleaded parties) include both the indemnifying
          party and the indemnified party and representation of both
          parties by the same counsel would be inappropriate due to actual
          or potential differing interests between them.  It is understood
          that the indemnifying party shall not, in connection with any
          proceeding or related proceedings in the same jurisdiction, be
          liable for (a) the fees and expenses of more than one separate
          firm (in addition to any local counsel) for the Placement Agents
          and all Persons, if any, who control the Placement Agents within
          the meaning of either Section 15 of the 1933 Act or Section 20 of
          the 1934 Act, (b) the fees and expenses of more than one separate
          firm (in addition to any local counsel) for ICG and Funding,
          ICG's directors, their officers who sign the Shelf Registration
          Statement and each Person, if any, who controls ICG or Funding
          within the meaning of either such Section and (c) the fees and
          expenses of more than one separate firm (in addition to any local
          counsel) for all Holders and all Persons, if any, who control any
          Holders within the meaning of either such Section, and that all
          such fees and expenses shall be reimbursed as they are incurred. 
          In such case involving the Placement Agents and Persons who
          control any Placement Agent, such firm shall be designated in
          writing by Morgan Stanley.  In such case involving the Holders
          and such Persons who control Holders, such firm shall be
          designated in writing by the Majority Holders.  In all other
          cases, such firm shall be designated by ICG.  The indemnifying
          party shall not be liable for any settlement of any proceeding
          effected without its written consent but, if settled with such
          consent or if there be a final judgment for the plaintiff, the
          indemnifying party agrees to indemnify the indemnified party from
          and against any loss or liability by reason of such settlement or
          judgment.  Notwithstanding the foregoing sentence, if at any time
          an indemnified party shall have requested an indemnifying party
          to reimburse the indemnified party for fees and expenses of
          counsel as contemplated by the second and third sentences of this
          paragraph, the indemnifying party agrees that it shall be liable
          for any settlement of any proceeding effected without its written
          consent if (i) such settlement is entered into more than 30 days
          after receipt by such indemnifying party of the aforesaid request
          and (ii) such indemnifying party shall not have reimbursed the
          indemnified party for such fees and expenses of counsel in
          accordance with such request prior to the date of such
          settlement.  No indemnifying party shall, without the prior
          written consent of the indemnified party, effect any settlement
          of any pending or threatened proceeding in respect of which such
          indemnified party is or could have been a party and indemnity
          could have been sought hereunder by such indemnified party,
          unless such settlement includes an unconditional release of such
          indemnified party from all liability on claims that are the
          subject matter of such proceeding.

                    (d)  If the indemnification provided for in paragraph
          (a) or paragraph (b) of this Section 4 is unavailable to an
          indemnified party or insufficient in respect of any losses,
          claims, damages or liabilities, then each indemnifying party
          under such paragraph, in lieu of indemnifying such indemnified
          party thereunder, shall contribute to the amount paid or payable
          by such indemnified party as a result of such losses, claims,
          damages or liabilities in such proportion as is appropriate to
          reflect the relative fault of the indemnifying party or parties
          on the one hand and of the indemnified party or parties on the
          other hand in connection with the statements or omissions that
          resulted in such losses, claims, damages or liabilities, as well
          as any other relevant equitable considerations.  The relative
          fault of ICG, Funding and the Holders shall be determined by
          reference to, among other things, whether the untrue or alleged
          untrue statement of a material fact or the omission or alleged
          omission to state a material fact relates to information supplied
          by ICG and Funding or by the Holders and the parties' relative
          intent, knowledge, access to information and opportunity to
          correct or prevent such statement or omission.  The Holders'
          respective obligations to contribute pursuant to this Section
          4(d) are several in proportion to the respective number of
          Registrable Securities of such Holder that were registered
          pursuant to a Shelf Registration Statement.  

                    (e)  ICG, Funding and each Holder agree that it would
          not be just or equitable if contribution pursuant to this Section
          4 were determined by pro rata allocation or by any other method
                               --- ----
          of allocation that does not take account of the equitable
          considerations referred to in paragraph (d) above.  The amount
          paid or payable by an indemnified party as a result of the
          losses, claims, damages and liabilities referred to in paragraph
          (d) above shall be deemed to include, subject to the limitations
          set forth above, any legal or other expenses reasonably incurred
          by such indemnified party in connection with investigating or
          defending any such action or claim.  Notwithstanding the
          provisions of this Section 4, no Holder shall be required to
          contribute any amount in excess of the amount by which the total
          price at which Registrable Securities were sold by such Holder
          exceeds the amount of any damages that such Holder has otherwise
          been required to pay by reason of such untrue or alleged untrue
          statement or omission or alleged omission.  No Person guilty of
          fraudulent misrepresentation (within the meaning of Section 11(f)
          of the 1933 Act) shall be entitled to contribution from any
          Person who was not guilty of such fraudulent misrepresentation. 
          The remedies provided for in this Section 4 are not exclusive and
          shall not limit any rights or remedies which may otherwise be
          available to any indemnified party at law or in equity.

                    (f)  The indemnity and contribution provisions
          contained in this Section 4 shall remain operative and in full
          force and effect regardless of (i) any termination of this
          Agreement, (ii) any investigation made by or on behalf of the
          Placement Agents, any Holder or any Person controlling any
          Placement Agent or any Holder, or by or on behalf of ICG,
          Funding, their officers or ICG's directors or any Person
          controlling ICG or Funding and (iii) any sale of Registrable
          Securities pursuant to a Shelf Registration Statement.

                    5.   Miscellaneous.
                         -------------

                    (a)  No Inconsistent Agreements.  Neither ICG nor
                         --------------------------
          Funding has entered into, and on or after the date of this
          Agreement will not enter into, any agreement which is
          inconsistent with the rights granted to the Holders of
          Registrable Securities in this Agreement or otherwise conflicts
          with the provisions hereof.  The rights granted to the Holders
          hereunder do not in any way conflict with and are not
          inconsistent with the rights granted to the holders of ICG's or
          Funding's other issued and outstanding securities under any such
          agreements.

                    (b)  Amendments and Waivers.  The provisions of this
                         ----------------------
          Agreement, including the provisions of this sentence, may not be
          amended, modified or supplemented, and waivers or consents to
          departures from the provisions hereof may not be given unless ICG
          and Funding have obtained the written consent of Holders of at
          least a majority in aggregate liquidation preference of the
          outstanding Preferred Securities affected by such amendment,
          modification, supplement, waiver or consent; provided, however,
                                                       --------  -------
          that no amendment, modification, supplement, waiver or consents
          to any departure from the provisions of Section 4 hereof shall be
          effective as against any Holder of Registrable Securities unless
          consented to in writing by such Holder.

                    (c)  Notices.  All notices and other communications
                         -------
          provided for or permitted hereunder shall be made in writing by
          hand-delivery, registered first-class mail, telex, telecopier, or
          any courier guaranteeing overnight delivery (i) if to a Holder,
          at the most current address given by such Holder to ICG and
          Funding by means of a notice given in accordance with the
          provisions of this Section 5(c), which address initially is, with
          respect to the Placement Agents, the address set forth in the
          Placement Agreement; and (ii) if to ICG or Funding, initially at
          ICG's or Funding's addresses set forth in the Placement Agreement
          and thereafter at such other address, notice of which is given in
          accordance with the provisions of this Section 5(c).

                    All such notices and communications shall be deemed to
          have been duly given:  at the time delivered by hand, if
          personally delivered; five business days after being deposited in
          the mail, postage prepaid, if mailed; when answered back, if
          telexed; when receipt is acknowledged, if telecopied; and on the
          next business day if timely delivered to an air courier
          guaranteeing overnight delivery.

                    (d)  Successors and Assigns.  This Agreement shall
                         ----------------------
          inure to the benefit of and be binding upon the successors,
          assigns and transferees of each of the parties, including,
          without limitation and without the need for an express
          assignment, subsequent Holders; provided that nothing herein
                                          --------
          shall be deemed to permit any assignment, transfer or other
          disposition of Registrable Securities in violation of the terms
          of the Placement Agreement.  If any transferee of any Holder
          shall acquire Registrable Securities, in any manner, whether by
          operation of law or otherwise, such Registrable Securities shall
          be held subject to all of the terms of this Agreement, and by
          taking and holding such Registrable Securities such person shall
          be conclusively deemed to have agreed to be bound by and to
          perform all of the terms and provisions of this Agreement and
          such person shall be entitled to receive the benefits hereof. 
          The Placement Agents (solely in their capacity as Placement
          Agents) shall have no liability or obligation to ICG or Funding
          with respect to any failure by a Holder to comply with, or any
          breach by any Holder of, any of the obligations of such Holder
          under this Agreement.

                    (e)  Purchases and Sales of Securities.  ICG and
                         ---------------------------------
          Funding shall not, and shall use their best efforts to cause
          their affiliates (as defined in Rule 405 under the 1933 Act) not
          to, purchase and then resell or otherwise transfer any
          Securities.

                    (f)  Third Party Beneficiary.  The Holders shall be
                         -----------------------
          third party beneficiaries to the agreements made hereunder
          between ICG and Funding, on the one hand, and the Placement
          Agents, on the other hand, and each Holder shall have the right
          to enforce such agreements directly to the extent it deems such
          enforcement necessary or advisable to protect its rights or the
          rights of Holders hereunder.

                    (g)  Counterparts.  This Agreement may be executed
                         ------------
          manually or by facsimile in any number of counterparts, each of
          which when so executed shall be deemed to be an original and all
          of which taken together shall constitute one and the same
          agreement.

                    (h)  Headings.  The headings in this Agreement are for
                         --------
          convenience of reference only and shall not limit or otherwise
          affect the meaning hereof.

                    (i)  Governing Law; Submission to Jurisdiction.  This
                         -----------------------------------------
          Agreement shall be governed by and construed in accordance with
          the laws of the State of New York.  Each of ICG and Funding
          agrees to submit to the jurisdiction of any federal or state
          court located in the City of New York in any suit, action or
          proceeding with respect to this Agreement and for actions brought
          under the U.S. federal or state securities laws brought in any
          such court.

                    (j)  Severability.  In the event that any one or more
                         ------------
          of the provisions contained herein, or the application thereof in
          any circumstance, is held invalid, illegal or unenforceable, the
          validity, legality and enforceability of any such provision in
          every other respect and of the remaining provisions contained
          herein shall not be affected or impaired thereby.

          Agreement as of the date first written above.

                                      GUARANTEE

               2.1  GENERAL.  ICG irrevocably and unconditionally agrees to
          pay in full to the Holders of the Preferred Securities the
          Guarantee Payments with respect to the Preferred Securities, as
          and when due (except to the extent previously paid by Funding),
          regardless of any defense, right of set-off or counterclaim which
          Funding may have or assert.  ICG's obligation to make a Guarantee
          Payment may be satisfied by direct payment of the required
          amounts by ICG to the Holders of the Preferred Securities or by
          causing Funding to pay such amounts to such Holders.

               2.2  WAIVER OF CERTAIN RIGHTS.  ICG hereby waives, to the
          fullest extent permitted by applicable law, notice of acceptance
          of this Guarantee and of any liability to which it applies or may
          apply, presentment, demand for payment, protest, notice of
          nonpayment, notice of dishonor, notice of redemption and all
          other notices and demands.

               2.3  OBLIGATIONS NOT AFFECTED.  The obligations, covenants,
          agreements and duties of ICG under this Guarantee shall in no way
          be affected or impaired by reason of the happening from time to
          time of any of the following:

                    (a)  the release or waiver, by operation of law or
               otherwise, of the performance or observance by Funding of
               any express or implied agreement, covenant, term of
               condition relating to the Preferred Securities to be
               performed or observed by Funding;

                    (b)  the extension of time for the payment by Funding
               of all or any portion of the Dividends, Redemption Price,
               liquidation distribution or any other sums payable under the
               terms of the Preferred Securities or the extension of time
               for the performance of any other obligation under, arising
               out of, or in connection with, the Preferred Securities;

                    (c)  any failure, omission, delay or lack of diligence
               on the part of the Holders of Preferred Securities to
               enforce, assert or exercise any right, privilege, power or
               remedy conferred on such Holders pursuant to the terms of
               the Preferred Securities, or any action on the part of
               Funding granting indulgence or extension of any kind;

                    (d)  the voluntary or involuntary liquidation,
               dissolution, winding-up, sale of any collateral,
               receivership, insolvency, bankruptcy, assignment for the
               benefit of creditors, reorganization, arrangement,
               composition or readjustment of debt of, or other similar
               proceedings affecting, Funding or any of the assets of
               Funding;

                    (e)  any invalidity of, or defect or deficiency in, any
               of the Preferred Securities;

                    (f)  the settlement or compromise of any obligation
               guaranteed hereby or hereby incurred; or

                    (g)  to the fullest extent permitted by applicable law,
               any other circumstance whatsoever that might otherwise
               constitute a legal or equitable discharge or defense of a
               guarantor.

          There shall be no obligation of any Holders of Preferred
          Securities to give notice to, or obtain any consent of, ICG with
          respect to the happening of any of the foregoing.

               2.4  PROCEEDING DIRECTLY AGAINST ICG.  This Guarantee is a
          guarantee of payment and not of collection.  A Holder of
          Preferred Securities may enforce this Guarantee with respect to
          the Preferred Securities directly against ICG, and ICG waives any
          right or remedy to require that any action be brought against
          Funding or any other person or entity before proceeding against
          ICG.  Subject to Section 2.5 hereof, all waivers herein contained
          shall be without prejudice to the right of a Holder, at its
          option, to proceed against Funding,whether by separate action or
          by joinder.  ICG agrees that this Guarantee shall not be
          discharged except by payment of the Guarantee Payments in full
          (to the extent not previously paid by Funding) and by complete
          performance of all obligations under this Guarantee.

               2.5  SUBROGATION.  ICG shall be subrogated to all (if any)
          rights of the Holders of Preferred Securities against ICG in
          respect of any amounts paid to such Holders by ICG under this
          Guarantee and shall have the right to waive payment by Funding of
          any amount of Dividends in respect of which payment has been made
          to the Holders by it pursuant to Section 2.1 hereof; provided,
          however, that ICG shall not (except to the extent required by
          mandatory provisions of law) exercise any rights which it may
          acquire by way of subrogation or any indemnity, reimbursement or
          other agreement, in all cases as a result of a payment under this
          Guarantee, if, at the time of any such payment, any amounts are
          due and unpaid under this Guarantee.  If any amount shall be paid
          to ICG in violation of the preceding sentence, ICG agrees to hold
          such amount in trust for the Holders and to pay over such amount
          promptly to the Holders.

               2.6  INDEPENDENT OBLIGATIONS.  ICG acknowledges that its
          obligations hereunder are independent of the obligations of
          Funding with respect to the Preferred Securities and that ICG
          shall be liable as principal and sole debtor under this Guarantee
          to make Guarantee Payments in full pursuant to the terms of this
          Guarantee notwithstanding the occurrence of any event referred to
          in subsections (a) through (g), inclusive, of Section 2.3 hereof.

               2.7  TERMINATION.  This Guarantee shall terminate and be of
          no further force and effect as to the Preferred Securities of any
          series upon (a) full payment of the Redemption Price of all
          outstanding Preferred Securities, or (b) the exchange (in the
          manner provided in the LLC Agreement and the Declaration) of all
          of the Preferred Securities for ICG Common Stock.  In
          addition,this Guarantee will terminate completely upon the
          distribution to the holders of the Preferred Securities of all of
          the assets of Funding, including the ICG Preferred Stock, any
          interest on and principal of the Treasury Strips that are held in
          the Escrow Account and any ICG Common Stock that Funding received
          from ICG as a dividend (or otherwise) and has not distributed on
          the Preferred Securities or sold in the open market.
          Notwithstanding the foregoing, this Guarantee shall continue to
          be effective or, to the fullest extent permitted by applicable
          law, shall be reinstated, as the case may be, with respect to the
          Preferred Securities if at any time any Holder of such Preferred
          Securities must restore payment of any sums recovered on account
          of, or must redeliver any securities received on account of, such
          Preferred Securities or under this Guarantee for any reason
          whatsoever.

               2.8  SUBJECT TO INDENTURES.  The obligations of ICG under
          this Guarantee shall not be enforceable except to the extent
          permitted under the provisions of the indenture pursuant to which
          the 13 1/2% Senior Discount Notes due 2005 were issued, the
          indenture pursuant to which the 12 1/2% Senior Discount Notes due
          2006 were issued and the indenture pursuant to which the 11 5/8%
          Senior Discount Notes due 2007 were issued.


                                     ARTICLE III

                               CERTAIN COVENANTS OF ICG

               3.1  COVENANTS.  So long as the Preferred Securities remain
          outstanding, ICG shall: (a) not cause or permit any Common
          Securities to be transferred (other than in connection with a
          merger or consolidation); (b) maintain direct or indirect
          ownership of all outstanding Common Securities and any other
          limited liability company interests in Funding other than the
          Preferred Securities (except as may be permitted in the LLC
          Agreement); (c) not voluntarily liquidate, dissolve or wind-up
          itself (other than in connection with a merger or consolidation)
          or cause Funding (other than in connection with or after an
          exchange of all outstanding Preferred Securities) to liquidate,
          dissolve or wind-up; (e) to remain the Manager and to timely
          perform all of its duties as Manager (including the duty to cause
          Funding to declare and pay dividends on all outstanding Preferred
          Securities to the extent set forth in the LLC Agreement and the
          Declaration) and (f) subject to the terms of the Preferred
          Securities, use reasonable efforts to cause Funding to remain a
          Delaware limited liability company and otherwise continue to be
          treated as a partnership for United States federal income tax
          purposes.


                                      ARTICLE IV

                                        STATUS

          number of full shares of ICG Common Stock deliverable to the
          Holders upon the exchange of all outstanding Preferred Securities
          not theretofore converted by the Holders.

          benefit of the Holders. Except in connection with any permitted
          merger or consolidation of ICG with or into another entity or any
          permitted sale, transfer or lease of ICG's assets to another
          entity, ICG may not assign its rights or delegate its obligations
          under this Guarantee without the prior approval of the holders of
          at least a majority in liquidation preference of the Preferred
          Securities then outstanding. 

               6.3  AMENDMENTS.  Except with respect to any changes which
          do not have a material adverse effect on the rights of any
          Holders of Preferred Securities (in which case no vote will be
          required, provided that the board of directors of ICG makes a
          determination, evidenced by resolution, that such change will not
          have a material adverse effect on the holders of Preferred
          Securities), this Guarantee may be amended with respect to the

               another party at the direction of the Issuer (the "Issuer's
                                                                  --------

               as practicable.  

                    (c)  Upon (i) payment in full of the first thirteen
               scheduled dividend payments on the Preferred Securities or
               (ii) exchange of all of the Preferred Securities into shares
               of ICG Common Stock, the security interest in the Collateral
               (except, with respect to subsection (ii) in this Section
               4(c), the Class of Pledged Securities (as defined below), if
               any, that will mature within 15 days from the date of such
               exchange) evidenced by this Escrow Agreement and held in the
               Escrow Account will automatically terminate and be of no
               further force and effect and the Collateral (except, with
               respect to subsection (ii) in this Section 4(c), the Class

               days from the date of such exchange) shall promptly be paid
               over and transferred to the Issuer.  Furthermore, upon the
               release of any Collateral from the Escrow Account in
               accordance with the terms of this Escrow Agreement, whether
               upon release of Collateral to Holders as payment of
               dividends or otherwise, the security interest evidenced by
               this Escrow Agreement in such released Collateral will
               automatically terminate and be of no further force and
               effect.

                    (d)  At least three Business Days prior to the due date
               of each of the first thirteen scheduled dividend payments on
               the Preferred Securities, the Issuer shall give the Escrow
               Agent notice (by Issuer Order) as to whether such dividend
               payment will be made pursuant to Section 4(a) or 4(b) and
               the respective amounts of the dividend that will be paid
               from the Escrow Account and from Issuer Funds.  Any Issuer
               Funds to be used to make any dividend payment shall be
               delivered to the Escrow Agent, in immediately available
               funds, prior to 10 a.m. one business day prior to such
               dividend payment date.  If no such notice is given or such
               Issuer Funds have not been so delivered, the Escrow Agent
               will act pursuant to Section 4(a) as if it had received an
               Issuer Order pursuant thereto for the payment in full of the
               dividend then due from the Escrow Account.

                    (e)  Upon any Provisional Redemption, the Escrow Agent,
               pursuant to a written instruction given by the Issuer to the
               Escrow Agent, shall release from the Escrow Account and pay
               the Holders whose Preferred Securities are being redeemed
               pursuant to such Provisional Redemption, such Holders' pro
               rata share of the entire Collateral.

                    (f)  The Escrow Agent shall liquidate Collateral in the
               Escrow Account (pursuant to written instructions from
               Issuer) in order to make any scheduled payment of dividends
               or payment pursuant to Section 4(e) above unless there are
               sufficient funds in the Escrow Account on such dividend
               payment date.

                    (g)  In the event that, prior to November 15, 2000, a
               holder of the Preferred Securities exchanges such Preferred
               Securities with the Issuer for shares of ICG Common Stock in
               accordance with the LLC Agreement, the Escrow Agent,
               pursuant to a written notice of the Issuer, shall release
               from the Escrow Account an amount of each Class of Pledged
               Securities (other than the Class of Pledged Securities, if
               any, that will mature within 15 days from the date of such
               exchange) that are then held in the Escrow Account equal to
               all of the Pledged Securities in such Class of Pledged
               Securities multiplied by a fraction, the numerator of which
               is the number of Preferred Securities which are being
               exchanged and the denominator of which is all of the
               outstanding Preferred Securities; provided however, that the
               Escrow Agent shall only release each such Class of Pledged
               Securities to the extent that it receives from an officer of
               the Issuer a written notice stating that it is his/her
               reasonable opinion that after such release, the Pledged
               Securities remaining in the Escrow Account will be
               sufficient upon receipt of scheduled interest and/or
               principal payment of all remaining Pledged Securities
               thereafter held in the Pledged Account to provide payment
               for the remaining cash dividends due on the Preferred
               Securities.  Each group of Pledged Securities that will
               mature on or about a dividend payment date with respect to
               the Preferred Securities shall be considered, for purposes
               of this Section 4, a "Class of Pledged Securities".

                    (h)  Nothing contained in this Escrow Agreement shall
               (i) afford the Issuer any right to issue entitlement orders
               with respect to any security entitlement to the Pledged
               Securities or any securities account in which any such
               security entitlement may be carried, or otherwise afford the
               Issuer control of any such security entitlement or (ii)
               otherwise give rise to any rights of the Issuer with respect
               to the Pledged Securities, any security entitlement thereto
               or any securities account in which any such security
               entitlement may be carried, other than the Issuer's rights
               under this Escrow Agreement as the beneficial owner of
               Collateral pledged to and subject to the exclusive dominion
               and control (except as expressly provided in Sections 4(a),
               (b), (c), (e) and (g) hereof) of the Escrow Agent in its
               capacity as such (and not as a securities intermediary). 
               The Issuer acknowledges, confirms and agrees that the Escrow
               Agent is an entitlement holder of the security entitlements
               to the Pledged Securities solely as Escrow Agent for the
               Holders of the Preferred Securities and not as a securities
               intermediary.

                    SECTION 5.     Representations and Warranties.  The
                                   ------------------------------
          Issuer hereby represents and warrants that:

                    (a)  The execution and delivery by the Issuer of, and
               the performance by the Issuer of its obligations under, this
               Escrow Agreement will not contravene any provision of
               applicable law or the Certificate of Formation of the Issuer
               or any material agreement or other material instrument
               binding upon the Issuer or any of its subsidiaries or any
               judgment, order or decree of any governmental body, agency
               or court having jurisdiction over the Issuer or any of its
               subsidiaries, or result in the creation or imposition of any
               lien on any assets of the Issuer, except for the security
               interests granted under this Escrow Agreement; no consent,
               approval, authorization or order of, or qualification with,
               any governmental body or agency is required (i) for the
               performance by the Issuer of its obligations under this
               Escrow Agreement, (ii) for the pledge by the Issuer of the
               Collateral pursuant to this Escrow Agreement or (iii) except
               for any such consents, approvals, authorizations or orders
               required to be obtained by the Escrow Agent (or the Holders)
               for reasons other than the consummation of this transaction,
               for the exercise by the Escrow Agent of the rights provided
               for in this Escrow Agreement or the remedies in respect of
               the Collateral pursuant to this Escrow Agreement.

                    (b)  The Issuer is the beneficial owner of the
               Collateral, free and clear of any Lien or claims of any
               person or entity (except for the security interests granted
               under this Escrow Agreement).  No financing statement
               covering the Issuer's interest in the Pledged Securities is
               on file in any public office, other than the financing
               statements filed pursuant to this Escrow Agreement.

                    (c)  This Escrow Agreement has been duly authorized,
               validly executed and delivered by the Issuer and constitutes
               a valid and binding agreement of the Issuer, enforceable
               against the Issuer in accordance with its terms, except as
               (i) the enforceability hereof may be limited by bankruptcy,
               insolvency, fraudulent conveyance, preference,
               reorganization, moratorium or similar laws now or hereafter
               in effect relating to or affecting creditors' rights or
               remedies generally, (ii) the availability of equitable
               remedies may be limited by equitable principles of general
               applicability, (iii) the exculpation provisions and rights
               to indemnification hereunder may be limited by U.S. federal
               and state securities laws and public policy considerations
               and (iv) the waiver of rights and defenses contained in
               Section 11(b), Section 14.11 and Section 14.15 hereof may be
               limited by applicable law.

                    (d)  Upon the transfer to the Escrow Agent of the
               Pledged Securities and the acquisition by the Escrow Agent
               of a security entitlement thereto, in accordance with
               Section 3, the pledge of and grant of a security interest in
               the Collateral securing the payment of the Obligations for
               the benefit of the Escrow Agent and the Holders of the
               Preferred Securities will constitute a perfected security
               interest in such Collateral with first priority against all
               creditors of the Issuer (and any persons purporting to
               purchase any of the Collateral from the Issuer). 

                    (e)  There are no legal or governmental proceedings
               pending or, to the best of the Issuer's knowledge,
               threatened to which the Issuer or any of its subsidiaries is
               a party or to which any of the properties of the Issuer or
               any such subsidiary is subject that would materially
               adversely affect the power or ability of the Issuer to
               perform its obligations under this Escrow Agreement or to
               consummate the transactions contemplated hereby.

                    (f)  The pledge of the Collateral pursuant to this
               Escrow Agreement is not prohibited by law or governmental
               regulation (including, without limitation, Regulations G, T,
               U and X of the Board of Governors of the Federal Reserve
               System) applicable to the Issuer.

                    (g)  No Event of Default exists.

                    SECTION 6.     Further Assurances.  The Issuer will,
                                   ------------------
          promptly upon request by the Escrow Agent, execute and deliver or
          cause to be executed and delivered, or use its reasonable best
          efforts to procure, all assignments, instruments and other
          documents, all in form and substance reasonably satisfactory to
          the Escrow Agent, deliver any instruments to the Escrow Agent and
          take any other actions that are necessary or, in the reasonable
          opinion of the Escrow Agent, desirable to perfect, continue the
          perfection of, or protect the first priority of the Escrow
          Agent's security interest in and to the Collateral, to protect
          the Collateral against the rights, claims, or interests of third
          persons (other than any such rights, claims or interests created
          by or arising through the Escrow Agent) or to effect the purposes
          of this Escrow Agreement including those contemplated by the
          Offering Memorandum dated September 18, 1997 relating to the
          Preferred Securities.  The Issuer also hereby authorizes the
          Escrow Agent to file any financing or continuation statements in
          the United States with respect to the Collateral without the
          signature of the Issuer (to the extent permitted by applicable
          law).  The Issuer will promptly pay all reasonable costs incurred
          in connection with any of the foregoing within 45 days of receipt
          of an invoice therefor.  The Issuer also agrees, whether or not
          requested by the Escrow Agent, to take all actions that are
          necessary to perfect or continue the perfection of, or to protect
          the first priority of, the Escrow Agent's security interest in
          and to the Collateral, including the filing of all necessary
          financing and continuation statements, and to protect the
          Collateral against the rights, claims or interests of third
          persons (other than any such rights, claims or interests created
          by or arising through the Escrow Agent). 

                    SECTION 7.  Covenants.  The Issuer covenants and agrees
                                ---------
          with the Escrow Agent and the Holders of the Preferred Securities
          that from and after the date of this Escrow Agreement until the
          earlier of payment in full in cash of the Obligations:

                    (a)  that (i) it will not (and will not purport to)
               sell or otherwise dispose of, or grant any option or warrant
               with respect to, any of the Collateral or its beneficial
               interest therein, and (ii) it will not create or permit to
               exist any Lien or other adverse interest in or with respect
               to its beneficial interest in any of the Collateral (except
               for the security interests granted under this Escrow
               Agreement); and

                    (b)  that it will not (i) enter into any agreement or
               understanding that restricts or inhibits or purports to
               restrict or inhibit the Escrow Agent's rights or remedies
               hereunder, including, without limitation, the Escrow Agent's
               right to sell or otherwise dispose of the Collateral or (ii)
               fail to pay or discharge any tax, assessment or levy of any
               nature with respect to its beneficial interest in the
               Collateral not later than five days prior to the date of any
               proposed sale under any judgment, writ or warrant of
               attachment with respect to such beneficial interest.

                    SECTION 8.     Power of Attorney.  In addition to all
                                   -----------------
          of the powers granted to the Escrow Agent pursuant to the LLC
          Agreement, the Issuer hereby appoints and constitutes the Escrow
          Agent as the Issuer's attorney-in-fact (with full power of
          substitution) to exercise to the fullest extent permitted by law
          all of the following powers upon and at any time after the
          occurrence and during the continuance of an Event of Default: 
          (a) collection of proceeds of any Collateral; (b) conveyance of
          any item of Collateral to any purchaser thereof; (c) giving of
          any notices or recording of any Liens under Section 6 hereof; and
          (d) paying or discharging taxes or Liens levied or placed upon
          the Collateral, the legality or validity thereof and the amounts
          necessary to discharge the same to be determined by the Escrow
          Agent in its sole reasonable discretion, and such payments made
          by the Escrow Agent to become part of the Obligations of the
          Issuer to the Escrow Agent, due and payable immediately upon
          demand.  The Escrow Agent's authority under this Section 8 shall
          include, without limitation, the authority to endorse and
          negotiate any checks or instruments representing proceeds of
          Collateral in the name of the Issuer, execute and give receipt
          for any certificate of ownership or any document constituting
          Collateral, transfer title to any item of Collateral, sign the
          Issuer's name on all financing statements (to the extent
          permitted by applicable law) or any other documents deemed
          necessary or appropriate by the Escrow Agent to preserve, protect
          or perfect the security interest in the Collateral and to file
          the same, prepare, file and sign the Issuer's name on any notice
          of Lien, and to take any other actions arising from or incident
          to the powers granted to the Escrow Agent in this Escrow
          Agreement.  This power of attorney is coupled with an interest
          and is irrevocable by the Issuer.

                    SECTION 9.  No Assumption of Duties; Reasonable Care.
                                ----------------------------------------
          The rights and powers granted to the Escrow Agent hereunder are
          being granted in order to preserve and protect the security
          interest of the Escrow Agent and the Holders of the Preferred
          Securities in and to the Collateral granted hereby and shall not
          be interpreted to, and shall not impose any duties on the Escrow
          Agent in connection therewith other than those expressly provided
          herein or imposed under applicable law.  Except as provided by
          applicable law or by the LLC Agreement, the Escrow Agent shall be
          deemed to have exercised reasonable care in the custody and
          preservation of the Collateral in its possession if the
          Collateral is accorded treatment substantially equal to that
          which the Escrow Agent accords similar property held by the
          Escrow Agent for similar accounts, it being understood that the
          Escrow Agent in its capacity as such shall not have any
          responsibility for (a) ascertaining or taking action with respect
          to calls, conversions, exchanges, maturities or other matters
          relative to any Collateral, whether or not the Escrow Agent has
          or is deemed to have knowledge of such matters, (b) taking any
          necessary steps to preserve rights against any parties with
          respect to any Collateral or (c) investing or reinvesting any of
          the Collateral or any loss on any investment.  The Escrow Agent
          may reasonably rely on the written instructions of the Issuer
          without any further investigation on its part.  Furthermore, the
          Escrow Agent assumes no responsibility for the validity of the
          Pledged Securities nor the sufficiency of such Pledged Securities
          to cover the first thirteen dividend payments on the Preferred
          Securities.

                    SECTION 10.  Indemnity.  The Issuer shall indemnify,
                                 ---------
          hold harmless and defend the Escrow Agent and its directors,
          officers, agents and employees, from and against any and all
          claims, actions, obligations, liabilities and expenses, including
          reasonable defense costs, reasonable investigative fees and
          costs, and reasonable legal fees and damages arising from the
          Escrow Agent's performance as Escrow Agent under this Escrow
          Agreement, except to the extent that such claim, action,
          obligation, liability or expense is directly attributable to the
          bad faith, gross negligence or wilful misconduct of such
          indemnified person.

                    SECTION 11.  Remedies Upon Event of Default.  If any
                                 ------------------------------
          Event of Default under the LLC Agreement or default hereunder
          (any such Event of Default or default being referred to in this
          Escrow Agreement as an "Event of Default") shall have occurred
                                  ----------------
          and be continuing:

                    (a)  The Escrow Agent and the Holders of the Preferred
               Securities shall have, in addition to all other rights given
               by law or by this Escrow Agreement or the LLC Agreement, all
               of the rights and remedies with respect to the Collateral of
               a secured party under the UCC in effect in the State of New
               York at that time.  In addition, with respect to any
               Collateral that shall then be in or shall thereafter come
               into the possession or custody of the Escrow Agent, the
               Escrow Agent may sell or cause the same to be sold at any
               broker's board or at public or private sale, in one or more
               sales or lots, at such price or prices as the Escrow Agent
               may deem best, for cash or on credit or for future delivery,
               without assumption of any credit risk.  The purchaser of any
               or all Collateral so sold shall thereafter hold the same
               absolutely, free from any claim, encumbrance or right of any
               kind whatsoever created by or through the Issuer.  Unless
               any of the Collateral threatens, in the reasonable judgment
               of the Escrow Agent, to decline speedily in value or is or
               becomes of a type sold on a recognized market, the Escrow
               Agent will give the Issuer reasonable notice of the time and
               place of any public sale thereof, or of the time after which
               any private sale or other intended disposition is to be
               made.  Any sale of the Collateral conducted in conformity
               with reasonable commercial practices of banks, insurance
               companies, commercial finance companies, or other financial
               institutions disposing of property similar to the Collateral
               shall be deemed to be commercially reasonable.  Any
               requirements of reasonable notice shall be met if such
               notice is mailed to the Issuer as provided in Section 14.1
               hereof at least ten (10) days before the time of the sale or
               disposition.  The Escrow Agent or any Holder of Preferred
               Securities may, in its own name or in the name of a designee
               or nominee, buy any of the Collateral at any public sale
               and, if permitted by applicable law, at any private sale. 
               All expenses (including court costs and reasonable
               attorneys' fees, expenses and disbursements) of, or incident
               to, the enforcement of any of the provisions hereof shall be
               recoverable from the proceeds of the sale or other
               disposition of the Collateral.

                    (b)  The Issuer further agrees to use its reasonable
               best efforts to do or cause to be done all such other acts
               as may be necessary to make such sale or sales of all or any
               portion of the Collateral pursuant to this Section 11 valid
               and binding and in compliance with any and all other
               applicable requirements of law.  The Issuer further agrees
               that a breach of any of the covenants contained in this
               Section 11 will cause irreparable injury to the Escrow Agent
               and the Holders of the Preferred Securities, that the Escrow
               Agent and the Holders of the Preferred Securities have no
               adequate remedy at law in respect of such breach and, as a
               consequence, that each and every covenant contained in this
               Section 11 shall be specifically enforceable against the
               Issuer, and the Issuer hereby waives and agrees not to
               assert any defenses against an action for specific
               performance of such covenants except for a defense that no

          Exchangeable Limited Liability Company Preferred Securities,
          liquidation preference $50 per preferred security, which will be

          officer of the Escrow Agent, on behalf of the Escrow Agent, makes
          the following certifications to the Issuer, ICG, Morgan Stanley &
          Co. Incorporated and Deutsche Morgan Grenfell Inc.  Capitalized
          terms used and not defined in this Officer's Certificate have the
          meanings set forth or referred to in the Escrow Agreement.

                    1. Substantially contemporaneously with the execution
          and delivery of this Officer's Certificate, the Escrow Agent has
          established a securities account in the name of "Norwest Bank
          Colorado, National Association, as Escrow Agent for the benefit
          of the holders of the 6 % Exchangeable Limited Liability Company
          Preferred Securities mandatorily redeemable 2009 of ICG Funding,
          LLC Collateral Escrow Account", Administrative Account No.
          1185943909 with respect to which the Escrow Agent is the
          entitlement holder and through which the Escrow Agent has
          acquired a security entitlement to the United States Treasury
          securities identified in Annex 1 to this Officer's Certificate
                                   -------
          (the "Pledged Securities") and has made appropriate book entries
          in its records establishing that the Pledged Securities and the
          Escrow Agent's securities entitlement thereto have been credited
          to and are held in the Norwest Bank Colorado, National
          Association's Administrative Account No. 1185943909 entitled
          "Norwest Bank Colorado, National Association, as Escrow Agent for
          the benefit of the holders of the 6 % Exchangeable Limited
          Liability Company Preferred Securities mandatorily redeemable
          2009 of ICG Funding, LLC Collateral Escrow Account" (the "Escrow
          Account").

                    2. The Escrow Agent has established and maintained and
          will maintain the Escrow Account and all securities entitlements
          and other positions carried in the Escrow Account solely in its
          capacity as Escrow Agent and has not asserted and will not assert
          any claim to or interest in the Escrow Account or any such
          securities entitlements or other positions except in such
          capacity.

                    3. The Escrow Agent has acquired its security
          entitlement to the Pledged Securities for value and without
          notice to an officer of the Escrow Agent of any adverse claim
          thereto.  Without limiting the generality of the foregoing, the
          Pledged Securities are not and the Escrow Agent's security
          entitlement to the Pledged Securities is not, to the Escrow
          Agent's knowledge, subject to any lien granted by the Escrow
          Agent in favor of any securities intermediary (including, without
          limitation, the Federal Reserve Bank of New York) through which
          the Escrow Agent derives its security entitlement to the Pledged
          Securities.

                    4. The Escrow Agent has not caused or permitted the
          Pledged Securities or its security entitlement thereto to become
          subject to any Lien created by or arising through the Escrow
          Agent.

          or power to vote on any question or matter or in any proceeding
          or to be represented at, or to receive notice of, any meeting of
          Members.

                    4.   Dividends.  (a)  The Holders shall be entitled to
                         ---------
          receive, out of funds legally available therefor, cumulative cash
          dividends at a rate per annum of 6 3/4% of the liquidation
          preference of $50 per Preferred Security.  The amount of
          dividends payable for a full monthly dividend period shall be
          computed on a daily basis.  Dividends shall accrue from September
          24, 1997, and shall be payable quarterly in arrears on
          February 15, May 15, August 15 and November 15 of each year (each
          a "Dividend Payment Date") commencing November 15, 1997 to
          Holders of record at the close of business on February 1, May 1,
          August 1 and November 1 immediately preceding the Dividend
          Payment Date.  Dividends shall accrue and be cumulative from
          September 24, 1997 whether or not they have been earned or
          declared and whether or not there are funds of the Company
          legally available for the payment of dividends.  In the event
          that any date on which dividends are payable on the Preferred
          Securities is not a Business Day, then payment of the dividend
          payable on such date will be made on the next succeeding day
          which is a Business Day (and without any interest or other
          payment in respect of any such delay), except that if such
          Business Day is in the next succeeding calendar year, such
          payment shall be made on the immediately preceding Business Day,
          in each case with the same force and effect as if made on such
          date.

                    (b)  Dividends on the Preferred Securities will be paid
          to the extent that the Company has funds legally available for
          the payment of such dividends.  Amounts available to the Company
          for dividends to the holders of the Preferred Securities will be
          limited to shares of ICG Common Stock received by the Company
          from ICG as dividends on the ICG Preferred Stock (and proceeds
          from any sales of such ICG Common Stock by the Company) and the
          interest on and principal of the Treasury strips that are held in
          the Escrow Account.   Any such ICG Common Stock received by the
          Company may be paid as a dividend to the holders of the Preferred
          Securities (only after November 15, 2000) or sold in the open
          market and the cash proceeds of sale used to pay cash dividends
          on the Preferred Securities.

                    (c)  Through and including November 15, 2000, dividends
          on the Preferred Securities shall be paid in cash.  Thereafter,
          dividends on the Preferred Securities may be paid, at the
          Company's option, in (i) cash, (ii) ICG Common Stock, valued at
          90% of the Average Market Value of the ICG Common Stock, or
          (iii) any combination of cash or ICG Common Stock; provided that
          any dividend payment must be made in cash to the extent ICG shall
          have provided the Company with cash (whether through dividends on
          the ICG Preferred Stock or otherwise) to make all or any portion
          of such dividend payment.  If any dividend (or portion thereof)
          payable on any Dividend Payment Date is not paid in full on such
          Dividend Payment Date, the amount of such dividend that is
          payable and that is not paid on such date shall cumulate at the
          dividend rate, compounding quarterly, until paid in full.

                    (d)  ICG and the Company shall enter into a
          registration rights agreement with the placement agents (the
          "Registration Rights Agreement") pursuant to which ICG and the
          Company will, at ICG's expense, for the benefit of the holders of
          the Securities (i) use their best efforts to file with the
          Securities and Exchange Commission (the "Commission") within 90
          days after the Closing Date, a registration statement (the "Shelf
          Registration Statement") covering resales of the Securities, (ii)
          use their best efforts to cause the Shelf Registration Statement
          covering resales of the Securities to be declared effective by
          the Commission under the Securities Act within 180 days after the
          Closing Date and (iii) use their best efforts to keep effective
          the Shelf Registration Statement until two years (or for such
          longer period as may be provided for in the Registration Rights
          Agreement) after the Closing Date or such earlier date as all of
          the Securities shall have been disposed of pursuant to the Shelf
          Registration Statement or on which all Securities held by persons
          that are not affiliates of ICG or the Company may be resold
          without registration pursuant to Rule 144(k) under the Securities
          Act. 

                    If, on or prior to the 90th day following the Closing
          Date, the Shelf Registration Statement has not been filed with
          the Commission, additional dividends will accrue at an annual
          rate of 0.25% of the liquidation preference thereof until the
          Shelf Registration Statement is filed, and if on or prior to the
          180th day following the Closing Date, the Shelf Registration
          Statement is not declared effective, additional dividends shall
          accrue at an additional annual rate of 0.25% of the liquidation
          preference thereof until the Shelf Registration Statement is
          declared effective, payable on each Dividend Payment Date in (i)
          cash, (ii) ICG Common Stock, based upon 90% of the Average Market
          Value of the ICG Common Stock or (iii) any combination of cash or
          ICG Common Stock (provided that such payment must be made in cash
          to the extent ICG shall have provided the Company with cash
          (whether through dividends on the ICG Preferred Stock or
          otherwise)) to make all or any portion of such payment.

                    5.   Exchange.  (a)  The Preferred Securities shall be
                         --------
          exchangeable with the Company at any time, in whole or in part,
          prior to November 15, 2009 (the "Mandatory Redemption Date")
          (unless earlier redeemed), at the option of the holder thereof
          and in the manner described below, into shares of ICG Common
          Stock at an exchange rate (the "Exchange Rate") which shall
          initially be equal to 2.0811 shares of ICG Common Stock for each
          Preferred Security, subject to adjustment as described below.

                    A holder of a Preferred Security wishing to exercise
          its exchange right shall (i) deliver an exchange notice to ICG
          (in such capacity, the "Exchange Agent"), (ii) if required,
          furnish appropriate endorsements and transfer documents and
          (iii) if required, pay all transfer or similar taxes, and the
          Exchange Agent shall, on behalf of such holder, exchange such
          Preferred Securities with the Company for shares of ICG Common
          Stock and deliver such shares of ICG Common Stock to such holder. 
          The Company shall obtain such shares of ICG Common Stock by
          exchanging shares of the ICG Preferred Stock it holds with ICG
          for ICG Common Stock, pursuant to the terms of the ICG Preferred
          Stock.

                    Holders of Preferred Securities at the close of
          business on a dividend record date shall be entitled to receive
          the dividends payable on such Preferred Securities on the
          corresponding Dividend Payment Date notwithstanding the exchange
          of such Preferred Securities following such dividend record date
          but prior to such Dividend Payment Date.  Except as provided in
          the immediately preceding sentence, neither the Company nor ICG
          will make, or be required to make, any payment, allowance or
          adjustment for accumulated and unpaid dividends, whether or not
          in arrears, on exchanged Preferred Securities.  Each exchange
          will be deemed to have been effected immediately prior to the
          close of business on the day on which the related exchange notice
          was received by the Exchange Agent.

                    No fractional shares of ICG Common Stock shall be
          issued as a result of exchange, but in lieu thereof such
          fractional interest shall be paid by the Company in cash based on
          the last reported sale price of ICG Common Stock on the date the
          affected Preferred Securities are surrendered for exchange.

                    (b)  The Exchange Rate shall be adjusted from time to
          time by the Company as follows:

                    (i)  In case ICG shall pay a dividend or make a
               distribution, in shares of ICG Common Stock, on ICG Common
               Stock, the Exchange Rate in effect at the opening of
               business on the date following the date fixed for the
               determination of stockholders entitled to receive such
               dividend or other distribution shall be increased by
               multiplying such Exchange Rate by a fraction of which the
               denominator shall be the number of shares of ICG Common
               Stock outstanding at the close of business on the date fixed
               for such determination and the numerator shall be the sum of
               such number of shares and the total number of shares
               constituting such dividend or other distribution, such
               increase to become effective immediately after the opening
               of business on the day following the date fixed for such
               determination.  ICG will not pay any dividend or make any
               distribution on shares of ICG Common Stock held in the
               treasury of ICG.  If any dividend or distribution of the
               type described in this Section 5(b)(i) is declared but is
               not so paid or made and not required to be so paid or made,
               the Exchange Rate shall again be adjusted to the Exchange
               Rate which would then be in effect if such dividend or
               distribution had not been declared.

                    (ii) In case ICG shall issue rights or warrants to all
               holders of ICG Common Stock entitling them (for a period
               expiring within 45 days after the date fixed for
               determination of stockholders entitled to receive such
               rights or warrants) to subscribe for or purchase ICG Common
               Stock at a price per share less than the Average Market
               Value per share at the record date for the determination of
               stockholders entitled to receive such rights or warrants,
               the Exchange Rate in effect immediately prior thereto shall
               be adjusted so that the same shall equal the rate determined
               by multiplying the Exchange Rate in effect immediately prior
               to the date fixed for determination of stockholders entitled
               to receive such rights or warrants by a fraction the
               denominator of which shall be the number of shares of ICG
               Common Stock outstanding at the close of business on the
               date fixed for determination of stockholders entitled to
               receive such rights or warrants plus the number of shares
               which the aggregate offering price of the total number of
               shares so offered would purchase at such Average Market
               Value and the numerator of which shall be the number of
               shares of ICG Common Stock outstanding on the date fixed for
               determination of stockholders entitled to receive such
               rights or warrants plus the number of additional shares of
               ICG Common Stock offered for subscription or purchase.  Such
               adjustment shall be made successively whenever any such
               rights or warrants are issued, and shall become effective
               immediately after the opening of business on the day
               following the record date for the determination of the
               stockholders entitled to receive such rights or warrants. 
               In determining whether any rights or warrants entitle the
               holders to subscribe for or purchase shares of ICG Common
               Stock at less than such Average Market Value, and in
               determining the aggregate offering price of such shares of
               ICG Common Stock, there shall be taken into account any
               consideration received by the ICG for such rights or
               warrants, the value of such consideration, if other than
               cash, to be determined by the board of directors.  To the
               extent that shares of ICG Common Stock are not delivered or
               required to be delivered after the expiration of such rights
               or warrants, the Exchange Rate shall be readjusted to the
               Exchange Rate which would then be in effect had the
               adjustments made upon the issuance of such rights or
               warrants been made on the basis of delivery of only the
               number of shares of ICG Common Stock actually delivered.  If
               such rights or warrants are not so issued and not required
               to be so issued, the Exchange Rate shall again be adjusted
               to be the Exchange Rate which would then be in effect if
               such record date for the determination of stockholders
               entitled to receive such rights or warrants had not been
               fixed.

                    (iii)     In case outstanding shares of ICG Common
               Stock shall be subdivided into a greater number of shares of
               ICG Common Stock, the Exchange Rate in effect at the opening
               of business on the day following the day upon which such
               subdivision becomes effective shall be proportionately
               increased, and conversely, in case outstanding shares of ICG
               Common Stock shall be combined into a smaller number of
               shares of ICG Common Stock, the Exchange Rate in effect at
               the opening of business on the day following the day upon
               which such combination becomes effective shall be
               proportionately reduced, such reduction or increase, as the
               case may be, to become effective immediately after the
               opening of business on the day following the day upon which
               such subdivision or combination becomes effective.

                    (iv) In case ICG shall distribute to all holders of ICG
               Common Stock any shares of any class of capital stock of ICG
               (other than ICG Common Stock) or evidences of its
               indebtedness or assets (excluding cash dividends or other
               distributions to the extent paid from retained earnings of
               ICG) or rights or warrants to subscribe for or purchase any
               of its securities (excluding those referred to in
               subsection (c) above) (any of the foregoing hereinafter in
               this subsection the "Distributed Securities"), then in each
               such case the Exchange Rate shall be adjusted so that the
               same shall equal the rate determined by multiplying the
               Exchange Rate in effect on the record date with respect to
               such distribution by a fraction of which the denominator
               shall be the Average Market Value on such record date less
               the fair market value on such record date (as determined by
               the board of directors of ICG, whose determination shall be
               conclusive) of the Distributed Securities applicable to one
               share of ICG Common Stock and the numerator of which shall
               be the Average Market Value per share on the record date for
               the determination of shareholders entitled to receive such
               distribution; such adjustment shall become effective
               immediately prior to the opening of business on the day
               following such record date.  Notwithstanding the foregoing,
               in the event the then fair market value (as so determined)
               of the portion of the Distributed Securities applicable to
               one share of ICG Common Stock is equal to or greater than
               the Average Market Value on the relevant record date, in
               lieu of the foregoing adjustment, adequate provision shall
               be made so that each Holder shall have the right to receive
               upon exchange the amount of Distributed Securities such
               holder would have received had such holder exchanged each
               Preferred Security on such record date.  In the event that
               such distribution is not so paid or made, the Exchange Rate
               shall again be adjusted to the Exchange Rate which would
               then be in effect if such distribution had not been
               declared.  If the board of directors of ICG determines the
               fair market value of any distribution for purposes of this
               subsection by reference to the actual or when issued trading
               market for any securities, it must in doing so consider the
               prices in such market over the same period used in computing
               the Average Market Value.

                    Notwithstanding the foregoing provisions of this
               subsection, no adjustment shall be made hereunder for any
               distribution of Distributed Securities if ICG makes proper
               provision so that each Holder who exchanges a Preferred
               Security (or any portion thereof) after the record date for
               such distribution shall be entitled to receive upon such
               exchange, in addition to the shares of ICG Common Stock
               issuable upon such exchange, the amount and kind of
               Distributed Securities that such holder would have been
               entitled to receive if such holder had, immediately prior to
               such record date, exchanged such Preferred Security for ICG
               Common Stock, provided that, with respect to any Distributed
                             --------
               Securities that are convertible, exchangeable or
               exercisable, the foregoing provision shall only apply to the
               extent (and so long as) the Distributed Securities
               receivable upon exchange of such Preferred Security would be
               convertible, exchangeable or exercisable, as applicable,
               without any loss of rights or privileges for a period of at
               least 60 days following exchange of such Preferred Security.

                    (v)  In case ICG shall, by dividend or otherwise,
               distribute to all holders of ICG Common Stock cash
               (excluding (x) any quarterly cash dividend on the ICG Common
               Stock to the extent the aggregate cash dividend per share of
               ICG Common Stock in any fiscal quarter does not exceed the
               greater of (A) the amount per share of ICG Common Stock of
               the next preceding quarterly cash dividend on the ICG Common
               Stock to the extent such preceding quarterly dividend did
               not require any adjustment of the Exchange Rate pursuant to
               this subsection (as adjusted to reflect subdivisions or
               combinations of the ICG Common Stock), and (B) 3.75% of the
               average of the last reported sales price of the ICG Common
               Stock (determined as provided below) during the ten Trading
               Days next preceding the date of declaration of such dividend
               and (y) any dividend or distribution in connection with the
               liquidation, dissolution or winding up of the Company,
               whether voluntary or involuntary), then, in such case,
               unless ICG elects to reserve such cash for distribution to
               the Holders upon the exchange of the Preferred Securities so
               that any such Holder exchanging Preferred Securities will
               receive upon such exchange, in addition to the shares of ICG
               Common Stock to which such Holder is entitled, the amount of
               cash which such holder would have received if such Holder
               had, immediately prior to the record date for such
               distribution of cash, exchanged its Preferred Securities for
               ICG Common Stock, the Exchange Rate shall be adjusted so
               that the same shall equal the rate determined by multiplying
               the Exchange Rate in effect immediately prior to the close
               of business on such record date by a fraction of which the
               denominator shall be such Average Market Value on the record
               date less the amount of cash so distributed (and not
               excluded as provided above) applicable to one share of ICG
               Common Stock and the numerator of which shall be the Average
               Market Value on such record date; such adjustment to be
               effective immediately prior to the opening of business on
               the day following the record date; provided, however, that
                                                  --------  -------
               in the event the portion of the cash so distributed
               applicable to one share of ICG Common Stock is equal to or
               greater than the Average Market Value on the record date, in
               lieu of the foregoing adjustment, adequate provision shall
               be made so that each Holder shall have the right to receive
               upon exchange the amount of cash such Holder would have
               received had such Holder exchanged each Preferred Security
               on the record date.  If such dividend or distribution is not
               so paid or made, the Exchange Rate shall again be adjusted
               to be the Exchange Rate which would then be in effect if
               such dividend or distribution had not been declared.

                    If any adjustment is required to be made as set forth
               in this subsection as a result of a distribution that is a
               quarterly dividend, such adjustment shall be based upon the
               amount by which such distribution exceeds the amount of the
               quarterly cash dividend permitted to be excluded pursuant
               hereto.  If an adjustment is required to be made as set
               forth in this subsection above as a result of a distribution
               that is not a quarterly dividend, such adjustment shall be
               based upon the full amount of the distribution.

                    (vi) In case a tender or exchange offer made by ICG or
               any subsidiary of ICG for all or any portion of the ICG
               Common Stock shall expire and such tender or exchange offer
               shall involve the payment by ICG or such subsidiary of
               consideration per share of ICG Common Stock having a fair
               market value (as determined by the board of directors of ICG
               or, to the extent permitted by applicable law, a duly
               authorized committee thereof, whose determination shall be
               conclusive, and described in a resolution of the board of
               directors of ICG or such duly authorized committee thereof,
               as the case may be), at the last time (the "Expiration
               Time") tenders or exchanges may be made pursuant to such
               tender or exchange offer (as it shall have been amended),
               that exceeds the Average Market Value on the Trading Day
               next succeeding the Expiration Time, the Exchange Rate shall
               be adjusted so that the same shall equal the rate determined
               by multiplying the Exchange Rate in effect immediately prior
               to the Expiration Time by a fraction of which the
               denominator shall be the number of shares of ICG Common
               Stock outstanding (including any tendered or exchanged
               shares) on the Expiration Time multiplied by the Average
               Market Value on the Trading Day next succeeding the
               Expiration Time and the numerator of which shall be the sum
               of (x) the fair market value (determined as aforesaid) of
               the aggregate consideration payable to stockholders based on
               the acceptance (up to any maximum specified in the terms of
               the tender or exchange offer) of all shares validly tendered
               or exchanged and not withdrawn as of the Expiration Time
               (the shares deemed so accepted up to any such maximum, being
               referred to in this subsection as the "Purchased Shares")
               and (y) the product of the number of shares of ICG Common
               Stock outstanding (less any Purchased Shares) on the
               Expiration Time and the Average Market Value on the Trading
               Day next succeeding the Expiration Time; such adjustment to
               become effective immediately prior to the opening of
               business on the day following the Expiration Time.  If ICG
               is obligated to purchase shares pursuant to any such tender
               or exchange offer, but ICG is permanently prevented by
               applicable law from effecting any such purchases or all such
               purchases are rescinded, the Exchange Rate shall again be
               adjusted to be the Exchange Rate which would then be in
               effect if such tender or exchange offer had not been made.

                    (vii)     The "fair market value" shall mean the amount
               which a willing buyer under no compulsion to buy would pay a
               willing seller under no compulsion to sell in an arm's
               length transaction.  The "record date" shall mean, with
               respect to any dividend, distribution or other transaction
               or event in which the holders of ICG Common Stock have the
               right to receive any cash, securities or other property or
               in which the ICG Common Stock (or other applicable security)
               is exchanged for or converted into any combination of cash,
               securities or other property, the date fixed for
               determination of stockholders entitled to receive such cash,
               securities or other property (whether such date is fixed by
               the board of directors of ICG or by statute, contract or
               otherwise).

                    (viii)    Rights or warrants distributed by ICG to all
               holders of ICG Common Stock entitling the holders thereof to
               subscribe for or purchase shares of ICG's capital stock
               (either initially or under certain circumstances), which
               rights or warrants, until the occurrence of a specified
               event or events ("Trigger Event"):

                         (i)  are deemed to be transferred with such shares
                    of ICG Common Stock,

                         (ii) are not exercisable, and

                         (iii)     are also issued in respect of future
                    issuances of ICG Common Stock,

               shall not be deemed distributed for purposes of this
               Section 5 until the occurrence of the earliest Trigger
               Event.  In addition, in the event of any distribution of
               rights or warrants, or any Trigger Event with respect
               thereto, that shall have resulted in an adjustment to the
               Exchange Rate under this Section 5, (1) in the case of any
               such rights or warrants which shall all have been redeemed
               or repurchased without exercise by any holders thereof, the
               Exchange Rate shall be readjusted upon such final redemption
               or repurchase to give effect to such distribution or Trigger
               Event, as the case may be, as though it were a cash
               distribution, equal to the per share redemption or
               repurchase price received by a holder of ICG Common Stock
               with respect to such rights or warrants (assuming such
               holder had retained such rights or warrants), made to all
               holders of ICG Common Stock as of the date of such
               redemption or repurchase, and (2) in the case of any such
               rights or warrants all of which shall have expired without
               exercise by any holder thereof, the Exchange Rate shall be
               readjusted as if such issuance had not occurred.

                    (ix) No adjustment to the Exchange Rate shall be
               required unless such adjustment would require an increase or
               decrease of at least 1% in such rate; provided, however,
                                                     --------  -------
               that any adjustments which by reason of this subsection (i)
               are not required to be made shall be carried forward and
               taken into account in any subsequent adjustment.  All
               calculations under this Section 5 shall be made by the
               Company and shall be made to the nearest cent or to the
               nearest one hundredth of a share, as the case may be. 
               Anything in this Section 5 to the contrary notwithstanding,
               the Company and ICG shall be entitled to make such increases
               in the Exchange Rate, in addition to those required by this
               Section 5, as they in their discretion shall determine to be
               advisable in order that any stock dividends, subdivision of
               shares, distribution of rights to purchase stock or
               securities, or any distribution of securities convertible
               into or exchangeable for stock hereafter made by the Company
               to its stockholders shall not be taxable.  To the extent
               permitted by applicable law, the Company and ICG from time
               to time may increase the Exchange Rate by any amount for any
               period of time if the period is at least 20 days, the
               increase is irrevocable during the period and the board of
               directors of ICG shall have made a determination that such
               increase would be in the best interests of the Company and
               ICG, which determination shall be conclusive.  Whenever the
               Exchange Rate is so increased, the Company shall mail to
               Holders a notice of the increase.  The Company shall mail
               the notice at least 15 days before the date the increased
               Exchange Rate takes effect.  The notice shall state the
               increased Exchange Rate and the period it will be in effect.

                    (x)  Whenever the Exchange Rate is adjusted, as herein
               provided, ICG shall promptly prepare an officers'
               certificate setting forth the Exchange Rate after such
               adjustment and setting forth a brief statement of the facts
               requiring such adjustment.  Promptly after the preparation
               of such certificate, shall prepare a notice of such
               adjustment of the Exchange Rate setting forth the adjusted
               Exchange Rate and the date on which such adjustment becomes
               effective and shall mail such notice of such adjustment of
               the Exchange Rate to each Holder.

                    (xi) In any case in which this Section 5 provides that
               an adjustment shall become effective immediately after a
               record date for an event, the Company may defer until the
               occurrence of such event (i) issuing to any Holder of a
               Preferred Security exchanged after such record date and
               before the occurrence of such event the additional shares of
               ICG Common Stock issuable upon such exchange by reason of
               the adjustment required by such event over and above the ICG
               Common Stock issuable upon such exchange before giving
               effect to such adjustment and (ii) paying to such holder any
               amount in cash or additional shares in lieu of any
               fractional share.

                    (xii)     In case of a tender or exchange offer made by
               a person other than ICG or any subsidiary for an amount
               which increases the offeror's ownership of ICG Common Stock
               to more than 25% of the ICG Common Stock outstanding and
               shall involve the payment by such person of consideration
               per share of ICG Common Stock having a fair market value (as
               determined by the board of directors of ICG, whose
               determination shall be conclusive, and described in a
               resolution of the board of directors of ICG) at the last
               time (the "Expiration Time") tenders or exchanges may be
               made pursuant to such tender or exchange offer (as it shall
               have been amended) that exceeds the Average Market Value on
               the Trading Day next succeeding the Expiration Time, and in
               which, as of the Expiration Time the board of directors of
               ICG is not recommending rejection of the offer, the Exchange
               Rate shall be increased so that the same shall equal the
               price determined by multiplying the Exchange Rate in effect
               immediately prior to the Expiration Time by a fraction of
               which the denominator shall be the number of shares of ICG
               Common Stock outstanding (including any tendered or exchange
               shares) on the Expiration Time multiplied by the Average
               Market Value on the Trading Day next succeeding the
               Expiration Time and the numerator shall be the sum of (x)
               the fair market value (determined as aforesaid) of the
               aggregate consideration payable to stockholders based on the
               acceptance (up to any maximum specified in the terms of the
               tender or exchange offer) of all shares validly tendered or
               exchanged and not withdrawn as of the Expiration Time (the
               shares deemed so accepted, up to any such maximum, being
               referred to in this subsection as the "Purchased Shares")
               and (y) the product of the number of shares of ICG Common
               Stock outstanding (less any Purchased Shares) on the
               Expiration Time and the Average Market Value on the Trading
               Day next succeeding the Expiration Time, such increase to
               become effective immediately prior to the opening of
               business on the day following the Expiration Time.  In the
               event that such person is obligated to purchase shares
               pursuant to any such tender or exchange offer, but such
               person is permanently prevented by applicable law from
               effecting any such purchases or all such purchases are
               rescinded, the Exchange Rate shall again be adjusted to be
               the Exchange Rate which would then be in effect if such
               tender or exchange offer had not been made.  Notwithstanding
               the foregoing, the adjustment described in this Section
               5(b)(xii) shall not be made if, as of the Expiration Time,
               the offering documents with respect to such offer disclose a
               plan or intention to cause the Company to engage in a
               consolidation or merger of ICG or a sale of substantially
               all of ICG's assets.

                    5A.  Effect of Reclassification, Consolidation, Merger
                         -------------------------------------------------
          or Sale.  If any of the following events occur, namely (i) any
          -------
          reclassification or change of outstanding shares of ICG Common
          Stock (other than a change in par value, or from par value to no
          par value, or from no par value to par value, or as a result of a
          subdivision or combination), (ii) any consolidation, merger or
          combination of ICG with another person as a result of which
          holders of ICG Common Stock shall be entitled to receive stock,
          securities or other property or assets (including cash) with
          respect to or in exchange for such ICG Common Stock, or (iii) any
          sale or conveyance of the properties and assets of ICG as, or
          substantially as, an entirety to any other person as a result of
          which holders of ICG Common Stock shall be entitled to receive
          stock, securities or other property or assets (including cash)
          with respect to or in exchange for such ICG Common Stock, then
          the Manager or the successor or purchasing person, as the case
          may be, shall prepare and execute a supplement to this Written
          Action providing that each Preferred Security shall be exchanged
          for the kind and amount of shares of stock and other securities
          or property or assets (including cash) receivable upon such
          reclassification, change, consolidation, merger, combination,
          sale or conveyance by a holder of a number of shares of ICG
          Common Stock issuable upon exchange of Preferred Securities
          immediately prior to such reclassification, change,
          consolidation, merger, combination, sale or conveyance.  Such
          supplement shall provide for adjustments which shall be as nearly
          equivalent as may be practicable to the adjustments provided for
          in Section 5 hereof.  The Company shall cause notice of the
          execution of such supplement to be mailed to each Holder.  The
          above provisions of this Section shall similarly apply to
          successive reclassifications, consolidations, mergers,
          combinations, and sales.

                    5B.  Taxes on Shares Issued.  The issuance of stock
                         ----------------------
          certificates on exchanges of Preferred Securities shall be made
          without charge to the exchanging holder for any U.S. tax in
          respect of the issue thereof.  The Company shall not, however, be
          required to pay any tax which may be payable in respect of any
          transfer involved in the issue and delivery of stock in any name
          other than that of a Holder, and the Company shall not be
          required to issue or deliver any such stock certificate unless
          and until the person or persons requesting the issue thereof
          shall have paid to the Company the amount of such tax or shall
          have established to the satisfaction of the Company that such tax
          has been paid.

                    If ICG implements a stockholders' rights plan, such
          rights plan must provide that upon exchange of the Preferred
          Securities into ICG Common Stock the holders will receive, in
          addition to the ICG Common Stock issuable upon such exchange,
          such rights whether or not such rights have separated from the
          ICG Common Stock at the time of such exchange.

                    5C.  Fundamental Change.  Notwithstanding the
                         ------------------
          foregoing, but not in addition to the adjustments set forth
          elsewhere herein, if ICG or the Company makes an announcement of
          the occurrence or an imminent occurrence of a Fundamental Change
          at any time prior to the Mandatory Redemption Date, there will be
          an adjustment to the exchange rate of the Preferred Securities
          (the "Fundamental Change Exchange Rate") such that the exchange
          rate will thereafter equal the liquidation preference of the
          Preferred Securities, divided by the Fundamental Change Average
          Market Price, unless the Fundamental Change Exchange Rate is
          lower than the then current exchange rate of the Preferred
          Securities as calculated in the manner described above (in which
          case there will be no such adjustment to the exchange rate).

                    The term "Fundamental Change" means the occurrence of
          any transaction or event in connection with which all or
          substantially of all of the outstanding shares of ICG Common
          Stock shall be exchanged for, converted into, acquired for or
          constitute the right to receive stock, securities, other property
          or assets (including cash) of another entity or person (whether
          by means of an exchange offer, liquidation, tender offer,
          consolidation, merger, combination, reclassification,
          recapitalization or otherwise).

                    "Fundamental Change Average Market Value" of the ICG
          Common Stock means the arithmetic average of the Current Market
          Value for the ten trading days ending on the fifth business day
          prior to the date of the closing of the Fundamental Change.

                    5D.  No Adjustments.  Notwithstanding anything herein
                         --------------
          to the contrary, no adjustment will be required as a result of
          (a) the issuance of shares of ICG Common Stock as a result of any
          of the following (i) the grant or exercise of employee or
          director stock options (ii) the exercise of outstanding warrants
          or conversion or exchange of existing notes and securities
          (including exchange of Class A Common Shares of ICG Holdings
          (Canada), Inc.), (iii) a contribution to ICG's 401(k) plan or
          ICG's 401(k) Wrap Around Deferred Compensation Plan and (iv) in
          satisfaction of ICG's obligations under its Employee Stock
          Purchase Plan or (b) the issuance of ICG Common Stock as a
          dividend on or upon exchange of the Preferred Securities.  ICG
          Common Stock issued in connection with acquisitions of businesses
          or assets from persons that are not affiliates of ICG will be
          deemed to have been issued for a price at least equal to Average
          Market Value.

                    6.   Redemption.  (a)  Unless earlier redeemed or
                         ----------
          exchanged, the Preferred Securities must be redeemed (the
          "Mandatory Redemption"), out of funds legally available therefor,
          by the Company at a redemption price of 100% of the liquidation
          preference of the Preferred Securities plus accrued and unpaid
          dividends, if any, on the Mandatory Redemption Date.

                    (b)  The Preferred Securities are subject to redemption
          by the Company, in whole or in part, at any time after the
          Closing Date and on or prior to November 15, 2000 (a "Provisional
          Redemption"), at a redemption price of 103% of the liquidation
          preference of the Preferred Securities to be redeemed plus
          accrued and unpaid dividends, if any, to the date of redemption
          (the "Provisional Redemption Date"), in the event that the
          Average Market Value equals or exceeds the following Trigger
          Percentages of the Exchange Price then in effect for at least 20
          Trading Days in any consecutive 30-day Trading Day period ending
          on the Trading Day prior to the date of mailing of the notice of
          Provisional Redemption, if called for redemption in the 12-month
          period ending on November 15 of the indicated year:

                          YEAR                 TRIGGER PERCENTAGES
                          ----                 -------------------
                          1998                        170%
                          1999                        160
                          2000                        150

                    Upon any Provisional Redemption, the Company will make
          an additional payment in cash (the "Dividend Make-Whole Payment")
          with respect to the Preferred Securities called for redemption in
          an amount equal to the pro rata portion of the liquidation
          proceeds of any remaining Treasury strips held pursuant to the
          Escrow Agreement.  The Company will be obligated to make the
          Dividend Make-Whole Payment on all Preferred Securities called
          for Provisional Redemption, regardless of whether such Preferred
          Security is exchanged prior to the Provisional Redemption Date. 
          The Dividend Make-Whole Payment must be paid in cash.

                    (c)  The Preferred Securities are subject to optional
          redemption (an "Optional Redemption") on or after November 18,
          2000 (the "Initial Redemption Date").  At any time and from time
          to time on or after the Initial Redemption Date and until the
          Mandatory Redemption Date, the Company will have the right to
          redeem, in whole or in part, the Preferred Securities at a
          redemption price equal to the percentage of the liquidation
          preference set forth below, together with accrued and unpaid
          dividends, if any, to the date of redemption, if redeemed in the
          12-month period beginning on November 15 of the indicated year:

                             YEAR                   TRIGGER PERCENTAGES
                             ----                   -------------------
                             2000                          102%
                             2001                          101%

                             2002 and thereafter           100%

                    (d)  The redemption price pursuant to a Provisional
          Redemption, an Optional Redemption or the Mandatory Redemption
          may be paid, in each case at the Company's option, in (i) cash,
          (ii) ICG Common Stock, valued at 90% of the Average Market Value
          of the ICG Common Stock in the case of the Provisional Redemption
          or the Optional Redemption and 100% of the Average Market Value
          of the ICG Common Stock in the case of the Mandatory Redemption,
          or (iii) any combination of cash or ICG Common Stock; provided
          that the Company, in its notice of such redemption, must state
          whether the redemption price will be paid in cash, ICG Common
          Stock or a combination thereof, and provided that any payment
          must be made in cash to the extent ICG shall have provided the
          Company with cash (whether through dividends on the ICG Preferred
          Stock or otherwise) to make all or any portion of such payment
          with respect to such redemption. 

                    7.   Redemption and Exchange Procedures.  (a)  Notice
                         ----------------------------------
          of any redemption (optional or mandatory) of the Preferred
          Securities (a "Notice of Redemption") shall be irrevocable and
          shall be given by the Company by mail not fewer than 30 nor more
          than 60 calendar days prior to the date fixed for redemption
          thereof to ICG and to each Holder of Preferred Securities that
          are being redeemed.  For purposes of the calculation of the date
          of redemption and the date on which notices are given pursuant to
          this Section 7(a), a Notice of Redemption shall be deemed to be
          given on the day such notice is first mailed by first-class mail,
          postage prepaid, to each appropriate Holder of Preferred
          Securities.  A Notice of Redemption shall be addressed to each
          appropriate Holder of Preferred Securities at the address of such
          Holder appearing in the books and records of the Company.  If all
          of the Preferred Securities are represented by Book-Entry
          Interests, Notices of Redemption shall be sent to the Clearing
          Agency.  No defect in the Notice of Redemption or in the mailing
          thereof with respect to any Preferred Security shall affect the
          validity of the redemption proceedings with respect to any other
          Preferred Security.  If fewer than all the Preferred Securities
          are being redeemed, then any redemption shall be on a pro rata
          basis.

                    (b)  If the Preferred Securities are represented by
          Book-Entry Interests, the Company shall irrevocably deposit
          sufficient funds on the date fixed for redemption with the
          Clearing Agency and give the Clearing Agency irrevocable
          instructions and authority to pay the redemption price to the
          Holders of the Preferred Securities to be redeemed, and if the
          Preferred Securities are not represented by Book-Entry Interests,
          the Company shall irrevocably deposit such funds with the
          transfer agent for the Preferred Securities and give such
          transfer agent such irrevocable instructions and authority to pay
          the redemption price to the Holders of the Preferred Securities
          to be redeemed.  If a Notice of Redemption shall have been given
          and sufficient funds irrevocably deposited as required, then
          immediately prior to the close of business on the date of such
          deposit, all rights of the Holders of such Preferred Securities
          so called for redemption will cease, except the right of such
          Holders to receive the redemption price, but without additional
          interest from and after such redemption date.  In the event that
          any date fixed for redemption of Preferred Securities is not a
          Business Day, then payment of the redemption price payable on
          such date will be made on the next succeeding day which is a
          Business Day (and without any interest or other payment in
          respect of any such delay), except that if such Business Day
          falls in the next calendar year, such payment will be made on the
          immediately preceding Business Day.  In the event that payment of
          the redemption price is improperly withheld or refused and not
          paid either by the Company or by ICG (pursuant to the Guarantee),
          dividends on the Preferred Securities called for redemption will
          continue to accumulate at the then applicable rate to the date
          that the redemption price is actually paid and the Holders of
          such Preferred Securities may exercise all of their rights as
          Holders thereof.

                    8.   Liquidation Rights.  In the event of any voluntary
                         ------------------
          or involuntary liquidation, dissolution, winding-up or
          termination of the Company (each a "Liquidation"), the then
          holders of the Preferred Securities shall be entitled to receive
          out of the assets of the Company (which will include the ICG
          Preferred Stock, any interest on and principal of the Treasury
          Strips that are held in the Escrow Account, any ICG Common Stock
          that the Company received from ICG as a dividend (or otherwise)
          and have not distributed as a dividend on the Preferred
          Securities or sold in the open market, and any other assets of
          the Company), after satisfaction of liabilities to creditors, if
          any, distributions in an amount equal to the aggregate of the
          stated liquidation preference of $50 of Preferred Security plus
          accrued and unpaid dividends thereon to the date of payment (the
          "Liquidation Distribution").

                    If, upon any such Liquidation, the Liquidation
          Distribution can be paid only in part because the Company has
          insufficient assets available to pay in full the aggregate
          Liquidation Distribution, then the amounts payable by the Company
          on the Preferred Securities shall be paid on a pro rata basis. 
          ICG is obligated to pay dividends, consisting of ICG Preferred
          Stock, to the Company so that it will be able to make the
          Liquidation Distribution in full.

                    9.   Sinking Fund.  The Preferred Securities shall not
                         ------------
          be subject to the operation of a retirement or sinking fund. 

                    10.  Guarantee of Liabilities.  It shall be a condition
                         ------------------------
          precedent to the issuance of the Preferred Securities that ICG
          execute and deliver to the Company the Guarantee.

                    11.  Book-Entry Issuance.  (a)  The Depository Trust
                         -------------------
          Company, New York, New York ("DTC"), will initially act as the
          Clearing Agency.  The Preferred Securities will be issued only as
          fully-registered securities and will be initially registered in
          the name of Cede & Co. (DTC's partnership nominee).

                    (b)  DTC may discontinue providing its services as
          Clearing Agency with respect to the Preferred Securities by
          giving reasonable notice to the Company as provided in the
          agreement between the Company and DTC.  Under such circumstances,
          if a successor Clearing Agency is not obtained, ICG at its
          expense shall cause certificates for Preferred Securities to be
          printed and delivered as promptly as practicable.  If the ICG
          decides to discontinue use of the system of book-entry transfers
          through DTC (or a successor Clearing Agency), ICG at its expense
          shall cause certificates for Preferred Securities to be printed
          and delivered to the beneficial owners of the Preferred
          Securities as promptly as practicable.

                    (c)  In the event that the Preferred Securities do not
          remain in book-entry-only form, the following provisions will
          apply:

                         (i)  Registration of transfers of Preferred
               Securities will be effected without charge by or on behalf
               of the Company, but upon payment (and/or the giving of such
               indemnity as the Company or the Manager may require) in
               respect of any tax or other governmental charges which may
               be imposed in connection therewith.

                         (ii) Exchanges of Preferred Securities for shares
               of ICG Common Stock shall be effected without charge by or
               on behalf of the Company, but upon payment (and/or the
               giving of such indemnity as the Company or the Manager may
               require) in respect of any tax or other governmental charges
               which may be imposed in connection with the issuance of any
               shares of ICG Common Stock in the name of any person other
               than the Holder of the Preferred Security for which it is
               being exchanged or for any reason other than such exchange.

                         (iii)     The Company shall not be required to
               register or cause to be registered the transfer of Preferred
               Securities after such Preferred Securities have been called
               for redemption.

                    12.  Registrar and Transfer Agent.  The Company hereby
                         ----------------------------
          appoints American Stock Transfer & Trust Company as its initial
          registrar, transfer agent and paying agent for the Preferred
          Securities.  The Company may at any time designate an additional
          or substitute registrar, transfer agent and paying agent for the
          Preferred Securities and shall promptly notify the Holders of the
          Preferred Securities of any such designation.

                    13.  Transfer Restrictions.  The Preferred Securities
                         ---------------------
          have not been registered under the Securities Act and may not be
          offered or sold within the United States or to, or for the
          account or benefit of U.S. persons except pursuant to an
          exemption from, or in a transaction not subject to, the
          registration requirements of the Securities Act.  Accordingly,
          the Preferred Securities are being offered and sold only (i) to
          "qualified institutional buyers" (as defined in Rule 144A under
          the Securities Act) in compliance with Rule 144A and (ii) to
          Institutional Accredited Investors.

                    By its purchase of Preferred Securities, each purchaser
          of Preferred Securities will be deemed to:

                    1.   represent that it is purchasing the Preferred
          Securities for its own account or an account with respect to
          which it exercises sole investment discretion and that it and any
          such account is (i) a QIB, and it is aware that the sale to it is
          being made in reliance on Rule 144A or (ii) an Institutional
          Accredited Investor;

                    2.   acknowledge that the Securities have not been
          registered under the Securities Act and may not be offered or
          sold within the United States or to, or for the account or
          benefit of, U.S. persons except as set forth below;

                    3.   if it is a person other than a foreign purchaser
          outside the United States, agree that if it should resell or
          otherwise transfer any of the Securities within the period
          referred to in Rule 144(k) under the Securities Act after the
          original issuance of such Securities, it will do so only (i) to
          ICG or any subsidiary thereof, (ii) to a QIB in compliance with
          Rule 144A, (iii) outside the United States in compliance with
          Rule 904 under the Securities Act, (iv) pursuant to the exemption
          from registration provided by Rule 144 under the Securities Act
          (if available), (v) inside the United States to an Institutional
          Accredited Investor that, prior to such transfer, furnishes to
          the Transfer Agent a signed letter containing certain
          representations and agreements relating to the restrictions on
          transfer of the Securities (the form of which letter can be
          obtained from the Transfer Agent), and, if such transfer is in
          respect of an aggregate liquidation preference of Preferred
          Securities at the time of transfer of less than $250,000 or any
          other Securities, an opinion of counsel acceptable to the Company
          that such transfer is in compliance with the Securities Act or
          (vi) pursuant to an effective registration statement with the
          Securities Act.  Each Institutional Accredited Investor that is
          not a QIB and that is an original purchaser of the Preferred
          Securities will be required to sign an agreement to the foregoing
          effect.  Prior to any proposed transfer of any Securities (other
          than pursuant to an effective registration statement within the
          period referred to in Rule 144(k) under the Securities Act after
          the original issuance of such Securities, the holder thereof must
          check the appropriate box set forth on the reverse of its
          Certificate relating to the manner of such transfer and submit
          the certificate to the transfer agent;

                    4.   agree that it will deliver to each person to whom
          it transfers any of the Preferred Securities notice of any
          restrictions on transfer of such Preferred Securities;

                    5.   if it is a QIB, understand that the Preferred
          Securities will be represented by the restricted global Preferred
          Securities certificate.  Before any interest in the restricted
          global Preferred Securities certificate may be offered, sold,
          pledged or otherwise transferred to a person who is not a QIB,
          the transferee will be required to provide the transfer agent
          with a written certification (the form of which certification can
          be obtained from the transfer agent) as to compliance with the
          transfer restriction referred to above;

                    6.   understand that, until registered under the
          Securities Act, the Securities (other than those issued to
          foreign purchasers after appropriate certification or in
          substitution or exchange therefor) will bear a legend to the
          following effect (as applicable) unless otherwise agreed by the
          Company and the holder thereof;

                    Each certificate representing a Preferred Security will
          bear the following legend:

                    THIS PREFERRED SECURITY HAS NOT BEEN REGISTERED UNDER
          THE U.S. SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES
          ACT"), AND ACCORDINGLY, MAY NOT BE OFFERED OR SOLD WITHIN THE
          UNITED STATES OR TO, OR FOR THE ACCOUNT OR BENEFIT OF, U.S.
          PERSONS EXCEPT AS SET FORTH IN THE FOLLOWING SENTENCE.  BY ITS
          ACQUISITION HEREOF, THE HOLDER (1) REPRESENTS THAT (A) IT IS A
          "QUALIFIED INSTITUTIONAL BUYER" (AS DEFINED IN RULE 144A, UNDER
          THE SECURITIES ACT), (B) IT IS NOT A U.S. PERSON AND IS ACQUIRING
          THIS PREFERRED SECURITY IN AN OFFSHORE TRANSACTION IN COMPLIANCE
          WITH REGULATION S UNDER THE SECURITIES ACT, OR (C) IT IS AN
          INSTITUTIONAL "ACCREDITED INVESTOR" (AS DEFINED IN RULE
          501(A)(1),(2), (3) OR (7) OF REGULATION d UNDER THE SECURITIES
          ACT) (AN "INSTITUTIONAL ACCREDITED INVESTOR"), (2) AGREES THAT IT
          WILL NOT, WITHIN THE TIME PERIOD REFERRED TO UNDER RULE 144(K)
          UNDER THE SECURITIES ACT AS IN EFFECT ON THE DATE OF THE TRANSFER
          OF THIS PREFERRED SECURITY, RESELL OR OTHERWISE TRANSFER THIS
          PREFERRED SECURITY EXCEPT (A) TO ICG COMMUNICATIONS, INC. OR ANY
          SUBSIDIARY THEREOF, (B) TO A QUALIFIED INSTITUTIONAL BUYER IN
          COMPLIANCE WITH RULE 144A UNDER THE SECURITIES ACT, (C) OUTSIDE
          THE UNITED STATES IN AN OFFSHORE TRANSACTION IN COMPLIANCE WITH
          RULE 904 UNDER THE SECURITIES ACT, (D) PURSUANT TO THE EXEMPTION
          FROM REGISTRATION PROVIDED BY RULE 144 UNDER THE SECURITIES ACT
          (IF AVAILABLE), (E) INSIDE THE UNITED STATES TO AN INSTITUTIONAL
          ACCREDITED INVESTOR THAT, PRIOR TO SUCH TRANSFER, FURNISHES TO
          THE TRANSFER AGENT A SIGNED LETTER CONTAINING CERTAIN
          REPRESENTATIONS AND AGREEMENTS RELATING TO THE RESTRICTIONS ON
          TRANSFER OF THIS PREFERRED SECURITY (THE FORM OF WHICH LETTER CAN
          BE OBTAINED FROM THE TRANSFER AGENT) AND, IF SUCH TRANSFER IS IN
          RESPECT OF AN AGGREGATE LIQUIDATION PREFERENCE OF PREFERRED
          SECURITIES AT THE TIME OF TRANSFER OF LESS THAN $250,000 OR ANY
          OTHER SECURITIES, AN OPINION OF COUNSEL ACCEPTABLE TO THE ISSUER
          THAT SUCH TRANSFER IS IN COMPLIANCE WITH THE SECURITIES ACT OR
          (F) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE
          SECURITIES ACT AND (3) AGREES THAT IT WILL DELIVER TO EACH PERSON
          TO WHOM THIS PREFERRED SECURITY IS TRANSFERRED A NOTICE
          SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND.  IN CONNECTION WITH
          ANY TRANSFER OF THIS PREFERRED SECURITY WITHIN THE TIME PERIOD
          REFERRED TO ABOVE, THE HOLDER MUST CHECK THE APPROPRIATE BOX SET
          PERIOD REFERRED TO ABOVE, THE HOLDER MUST CHECK THE APPROPRIATE
          BOX SET FORTH ON THE REVERSE HEREOF RELATING TO THE MANNER OF
          SUCH TRANSFER AND SUBMIT THIS CERTIFICATE TO THE TRANSFER AGENT. 
          IF THE PROPOSED TRANSFEREE IS AN INSTITUTIONAL ACCREDITED
          INVESTOR, THE HOLDER MUST, PRIOR TO SUCH TRANSFER, FURNISH TO THE
          TRANSFER AGENT AND ICG FUNDING, LLC SUCH CERTIFICATIONS, LEGAL
          OPINIONS OR OTHER INFORMATION AS EITHER OF THEM MAY REASONABLY
          REQUIRE TO CONFIRM THAT SUCH TRANSFER IS BEING MADE PURSUANT TO
          AN EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE
          REGISTRATION REQUIREMENTS OF THE SECURITIES ACT, AS USED HEREIN,
          THE TERMS "OFFSHORE TRANSACTION," "UNITED STATES" AND "U.S.
          PERSON" HAVE THE MEANINGS GIVEN TO THEM BY REGULATIONS S UNDER
          THE SECURITIES ACT. THE OPERATING AGREEMENT CONTAINS A PROVISION
          REQUIRING THE TRANSFER AGENT TO REFUSE TO REGISTER ANY TRANSFER
          OF THE PREFERRED SECURITIES IN VIOLATION OF THE FOREGOING
          RESTRICTIONS.

                    Each stock certificate representing any ICG Common
          stock issuable upon exchange will bear the following legend
          (unless the resale of such ICG Common Stock is not subject to the
          registration requirements of the Securities Act):

                    THE COMMON STOCK EVIDENCED HEREBY HAS NOT BEEN
          REGISTERED UNDER THE U.S. SECURITIES ACT OF 1933, AS AMENDED (THE

          WITHIN THE UNITED STATES OR TO, OR FOR THE ACCOUNT OR BENEFIT OF,
          U.S. PERSONS EXCEPT AS SET FORTH IN THE FOLLOWING SENTENCE. THE
          HOLDER HEREOF AGREES THAT UNTIL THE EXPIRATION OF THE TIME PERIOD
          REFERRED TO IN RULE 144(K), (1) IT WILL NOT RESELL OR OTHERWISE
          TRANSFER THE COMMON STOCK EVIDENCED HEREBY EXCEPT (A) TO ICG
          COMMUNICATIONS, INC. OR ANY SUBSIDIARY THEREOF, (B) TO A

          THE SECURITIES ACT, (C) INSIDE THE UNITED STATES TO AN
          INSTITUTIONAL ACCREDITED INVESTOR THAT, PRIOR TO SUCH TRANSFER,
          FURNISHES TO THE TRANSFER AGENT A SIGNED LETTER CONTAINING
          CERTAIN REPRESENTATIONS AND AGREEMENTS RELATING TO THE
          RESTRICTIONS OR TRANSFER OF THE COMMON STOCK EVIDENCED HEREBY

          AGENT), (D) OUTSIDE THE UNITED STATES IN COMPLIANCE WITH RULE 904
          UNDER THE SECURITIES ACT, (E) PURSUANT TO THE EXEMPTION FROM
          REGISTRATION PROVIDED BY RULE 144 UNDER THE SECURITIES ACT (IF
          AVAILABLE), OR (F) PURSUANT TO AN EFFECTIVE REGISTRATION
          STATEMENT, (2) PRIOR TO SUCH TRANSFER (OTHER THAN A TRANSFER
          PURSUANT TO CLAUSE (F) ABOVE), IT WILL FURNISH TO THE TRANSFER
          AGENT OR ICG COMMUNICATIONS, INC. SUCH CERTIFICATIONS, LEGAL
          OPINIONS OR OTHER INFORMATION AS IT MAY REASONABLY REQUIRE TO
          CONFIRM THAT SUCH TRANSFER IS BEING MADE PURSUANT TO AN EXEMPTION
          FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION
          REQUIREMENTS OF THE SECURITIES ACT AND (3) IT WILL DELIVER TO
          EACH PERSON TO WHOM THE COMMON STOCK EVIDENCED HEREBY IS
          TRANSFERRED (OTHER THAN A TRANSFER PURSUANT TO CLAUSE (F) ABOVE)
          A NOTICE SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND. THIS LEGEND
          WILL BE REMOVED UPON THE EARLIER OF THE TRANSFER OF THE COMMON
          STOCK EVIDENCED HEREBY PURSUANT TO CLAUSE (F) ABOVE OR THE
          EXPIRATION OF ICG COMMUNICATIONS, INC. AND THE TRANSFER AGENT
          THAT THE COMMON STOCK HAS BEEN OR IS BEING OFFERED AND SOLD IN
          COMPLIANCE WITH RULE 904 UNDER THE SECURITIES ACT, AS USED
          HEREIN, THE TERMS "UNITED STATES" AND "U.S. PERSON" HAVE THE
          MEANINGS GIVEN TO THEM BY REGULATION S UNDER THE SECURITIES ACT.

                    7.   and acknowledge that ICG, the Company and the
          placement agents and others will rely upon the truth and accuracy
          of the foregoing acknowledgements, represents and agreements, and

                    1.  DESIGNATION AND AMOUNT.  The distinctive designation
                        ----------------------
          of such  series is "Preferred Stock  Mandatorily Redeemable 2009"
          (hereinafter in this Resolution called the "Preferred Stock"), and
                                                      ---------------
          the number of shares constituting such series shall be 13,225.

                    2.   RANK.  The Preferred Stock shall, with respect to
                         ----
          dividend  rights  and  rights  of  liquidation,  winding  up  and
          dissolution,  rank (i) senior to  all classes of  common stock of
          the  Corporation  and to  each other  class  of capital  stock or
          series  of preferred  stock  established after  the date  of this
          Resolution by the  Board of Directors  the terms of which  do not
          expressly provide that it ranks senior to or on a parity with the
          Preferred Stock  as to  dividend distributions  and distributions
          upon   the  liquidation,   winding-up   or  dissolution   of  the
          Corporation (collectively  referred to  with the common  stock of
          the Corporation  as "Junior Securities");  (ii) on a  parity with
          any class of capital stock or series of preferred stock issued by

          the Board of Directors, the terms of which expressly provide that
          such class  or series will  rank on  a parity with  the Preferred
          Stock  as to  dividend distributions  and distributions  upon the
          liquidation,  winding-up   or  dissolution  of   the  Corporation
          (collectively  referred  to as  "Parity  Securities"); and  (iii)

          expressly provide that such  class or series will rank  senior to

          distributions upon liquidation, winding-up  or dissolution of the
          Corporation  (collectively referred  to as  "Senior Securities").
          The Preferred Stock will be subject  to the issuance of series of
          Junior  Securities,  Parity  Securities  and  Senior  Securities;
          provided  that the  Corporation may  not issue  any new  class of
          Senior Securities without the approval of the holders of at least
          a majority  of the  shares of  Preferred Stock  then outstanding,
          voting  or  consenting, as  the case  may  be, separately  as one
          class.

                    3.   DIVIDENDS.  The registered holder ("Holder") of
                         ---------
          shares of the Preferred Stock shall be entitled to receive, when,
          as and if declared by the  Board of Directors of the Corporation,
          out of  funds legally available therefor, dividends at the annual
          rate of 5.95% of the liquidation preference per share through and
          including November  15, 2000, and thereafter  as described below.
          Such  dividends shall  be  cumulative, whether  or not  earned or
          declared,  on a  daily basis  from the  date of  issuance of  the
          Preferred  Stock, and shall be payable quarterly in arrears on or
          prior to February 15, May 15,  August 15, and November 15 of each
          year commencing on February 15, 1998 (each of such dates being  a
          "dividend payment  date"), with respect to  the period commencing
          with  the  date  of  issuance  of  the  Preferred  Stock  or  the
          immediately preceding dividend payment date and ending on the day
          preceding  such respective  dividend payment  date (each  of such
          periods being a "dividend period"), to stockholders of  record on
          the  preceding February  1,  May 1,  August  1, and  November  1,
          respectively  (each,  a "regular  record  date").   Any  dividend
          payments made with  respect to  shares of Preferred  Stock on  or
          before  November  15,  2000, shall  be  made  in  such number  of
          additional fully paid and nonassessable shares of Preferred Stock
          having an aggregate liquidation preference equal to the amount of
          such dividends,  and the  issuance of  such additional  shares of
          Preferred Stock  shall constitute full payment  of such dividend.
          All shares of Preferred  Stock issued as a dividend  with respect
          to the Preferred Stock will thereupon be duly authorized, validly
          issued,  fully paid and nonassessable  and free of  all liens and
          charges.   After November  15, 2000,  dividends on  the Preferred
          Stock  may be  paid,  in  the sole  discretion  of  the Board  of
          Directors  of the  Corporation, in  cash or  in shares  of common
          stock,  $.01 par  value  per share  of  the Corporation  ("Common
          Stock"), in an amount that will enable the Holder (i) to transfer
          such Common Stock  to the  holders of  the Holder's  Exchangeable
          Limited  Liability  Company  Preferred Securities  (the  "Funding
          Preferred  Securities")  in  full  payment of  dividends  on  the
          Funding Preferred Securities, valued at 90% of the Average Market
          Value (as defined  below) of the  Common Stock, or  (ii) to  sell
          such shares of Common Stock  in the open market in order  for the
          Holder to make  full dividend payments  on the Funding  Preferred
          Securities in cash, in  each case for the corresponding  dividend
          period  with respect to the Funding Preferred Securities.  At any
          time and  from time to  time after the issuance  of the Preferred
          Stock, the Corporation may, as, when and if declared by the Board
          of  Directors,  declare additional  dividends  to  the Holder  in
          shares  of Common Stock, in such amounts  in order for the Holder
          to have sufficient funds in cash, following a sale thereof by the
          Holder,  to satisfy all  obligations with respect  to the Funding
          Preferred Securities.

                         If  on or  prior  to the  90th  day following  the
          Closing Date  the shelf  registration statement with  respect to,
          among other things, the  Funding Preferred Securities (the "Shelf
          Registration Statement")  has not  been filed by  the Corporation
          and  Funding with  the  Securities and  Exchange Commission  (the
          "Commission"), dividends will accrue at an additional annual rate
          of  0.25% of the  liquidation preference thereof  until the Shelf
          Registration Statement is filed, and if  on or prior to the 180th
          day following the Closing  Date, the Shelf Registration Statement
          has not been declared effective by the Commission, dividends will
          accrue at an additional  annual rate of 0.25% of  the liquidation
          preference  thereof  until  the Shelf  Registration  Statement is
          declared effective  by the  Commission, payable on  each Dividend
          Payment Date in (i) cash, (ii) shares  of Common Stock, valued at
          90% of the Average Market Value  of the Common Stock or (iii) any
          combination  of  cash  or  Common Stock.    "Closing  Date" means
          September 24, 1997.   "Average Market Value" of the  Common Stock
          means the average of the Current Market Value for the ten trading
          days  ending on the second  business day prior  to the applicable
          date  of payment.   "Current  Market Value"  of the  Common Stock
          means (i) the Volume  Weighted Average Price, as reported  on the
          Nasdaq  National Market or (ii)  the average of  the high and low
          sales  prices of  the  Common Stock,  if  reported on  any  other
          national securities exchange.

                    4.   LIQUIDATION PREFERENCE.
                         ----------------------

                         Upon  any  voluntary  or involuntary  liquidation,
          dissolution  or  winding-up   of  the  Corporation,  holders   of
          Preferred Stock will be entitled to be paid, out of the assets of
          the Corporation available for distributions, $10,000 per share of
          Preferred  Stock, plus an amount in cash equal to accumulated and
          unpaid  dividends  thereon to  the  date  fixed for  liquidation,
          dissolution  or  winding-up  (including  an  amount  equal  to  a
          prorated dividend for the  period from the last dividend  payment
          date to the  date fixed for liquidation,  dissolution or winding-
          up), before any  distribution is made  on any Junior  Securities,
          including,  without  limitation,  Common  Stock.   If,  upon  any
          voluntary  or involuntary liquidation,  dissolution or winding-up
          of  the  Corporation, the  amounts  payable with  respect  to the
          Preferred Stock and all  other Parity Securities are not  paid in
          full,  the  holders  of  the  Preferred  Stock   and  the  Parity
          Securities will share equally and ratably in any distribution  of
          assets of the Corporation with respect to the Preferred Stock and
          the  Parity Securities,  in  proportion to  the full  liquidation
          preference and accumulated and unpaid dividends  to which each is
          entitled.   After payment of  the full amount  of the liquidation
          preferences and  accumulated and  unpaid dividends to  which they
          are entitled, the  Holders will  not be entitled  to any  further
          participation in any distribution of assets of the Corporation.

                    5.   MANDATORY REDEMPTION.
                         --------------------

                         All  of the  shares  of Preferred  Stock shall  be
          subject   to  mandatory   redemption  by  the   Corporation  (the
          "Mandatory Redemption"), at  a redemption price equal to  100% of
          the liquidation  preference per share, together  with accrued and
          unpaid dividends thereon to  the redemption date, in cash  out of
          funds  legally  available  therefor  without  interest,  two  (2)
          business days prior  to November  15, 2009.   Upon the  Mandatory
          Redemption, ICG will  declare and  pay a special  dividend in  an
          amount equal  to the  shortfall,  if any,  in the  assets of  the
          Holder necessary for Holder  to complete its mandatory redemption
          of the Funding Preferred Securities.

                    6.   PROVISIONAL REDEMPTION.
                         ----------------------

                         The Preferred Stock shall be subject to redemption
          by the  Corporation (an "ICG Provisional Redemption") in whole or
          in part,  at any time prior to November 15, 2000, at a redemption
          price  equal  to  103%  of  the  liquidation  preference  of  the
          Preferred Stock to be redeemed plus accrued and unpaid dividends,
          if  any,  to the  date of  redemption.  Upon any  ICG Provisional
          Redemption, ICG will  declare and  pay a special  dividend in  an
          amount  equal to  the shortfall,  if any,  in the  assets of  the
          Holder  necessary  for the  Holder  to  complete its  provisional
          redemption of the Funding Preferred Securities.

                    7.   OPTIONAL REDEMPTION BY THE CORPORATION.
                         --------------------------------------

                         The  Preferred  Stock  will  also  be  subject  to
          optional  redemption   by  the  Corporation  (an   "ICG  Optional
          Redemption") on or  after November 18, 2000.  In  such event, the
          Corporation shall  redeem, in  whole  or in  part, the  Preferred
          Stock  at a  redemption  price equal  to  the percentage  of  the
          liquidation preference set forth below, together with accrued and
          unpaid  dividends, if any, to the redemption date, if redeemed in
          the 12-month  period beginning on  November 15  of the  indicated
          year:

                                                REDEMPTION
                          YEAR                     PRICE
                          ----                  ----------

                          2000                     102%

                          2002 and thereafter      100%

                         Upon any ICG Optional Redemption, ICG will declare
          and  pay a special dividend in  an amount equal to the shortfall,
          if  any, in  the assets  of  the Holder  necessary for  Holder to
          complete  its   optional  redemption  of  the  Funding  Preferred
          Securities.


                    8.   METHOD OF PAYMENT OF REDEMPTION PRICE.
                         -------------------------------------

                         All  payments  pursuant  to  an   ICG  Provisional
          Redemption,   an  ICG  Optional   Redemption  or   the  Mandatory
          Redemption may be paid, in each case at the Corporation's option,
          in (i)  cash, (ii) shares of  Common Stock, valued at  90% of the
          Average Market  Value of the Common  Stock in the case  of the an
          ICG Provisional Redemption or an ICG Optional Redemption and 100%
          of the  Average Market Value of  the Common Stock in  the case of
          the  Mandatory Redemption,  or (iii) any  combination of  cash or
          Common Stock.

                    9.   EXCHANGE OF PREFERRED STOCK.
                         ---------------------------

                         The  Preferred Stock  is exchangeable  into Common
          Stock at the option of the Holder, upon the Holder's receipt of a
          request from a holder of Funding Preferred Securities to exchange
          such Funding Preferred Securities for Common Stock, at an initial
          exchange  rate of 416.23304 shares of Common Stock for each share
          of Preferred Stock, subject to the same adjustments that are made
          to  the  exchange  rate  of  the  Funding  Preferred  Securities.
          Notwithstanding  the foregoing,  the number  of shares  of Common
          Stock issuable to the  Holder upon exchange of the  ICG Preferred
          Stock shall equal the  number of shares of Common  Stock issuable
          by the Holder upon exchange of the Funding Preferred Securities

                         In  the event  a holder  of the  Funding Preferred
          Securities wishes to exchange  such Preferred Securities with the
          Holder  prior to November 15,  2000, the Holder  shall deliver to
          the Company (i)  a number of shares  of Preferred Stock equal  to
          all of  the outstanding Preferred Stock multiplied by a fraction,
          the  numerator  of  which  is the  number  of  Funding  Preferred
          Securities which are presented to the Holder for exchange and the
          denominator of which is all of the outstanding  Funding Preferred
          Securities (the "Ratio"),  and (ii)  an amount of  each Class  of
          Treasury Strips (other than the Class of Treasury Strips, if any,
          that will  mature within 15 days from  the date of such exchange)
          then  held by  Funding or  an escrow  agent equal  to all  of the
          Treasury Strips in such Class multiplied by the Ratio.

                         "Treasury  Strips" means the  U.S. Treasury strips
          held  by Funding  or  an escrow  agent  to  secure the  first  13
          dividend  payments on  the  Funding Preferred  Securities.   Each
          group of Treasury Strips that  is payable on or about  a dividend
          payment date shall be considered, for purposes of this paragraph,
          a "Class of Treasury Strips."

                         If  the  Corporation  implements  a  stockholders'
          rights plan, such rights plan must provided that upon exchange of
          Preferred  Stock for  Common Stock  the Holder  will receive,  in
          addition to the  Common Stock issuable  upon such exchange,  such
          rights  whether or not such rights have separated from the Common
          Stock at the time of such exchange.

                    10.  VOTING RIGHTS.  The holders of record of shares of
                         -------------
          Preferred Stock shall not be entitled to any voting rights except
          as otherwise provided  herein or  required by law.   Without  the
          affirmative  vote of  the holders of  more than  50% of  the then
          outstanding shares of Preferred Stock, voting  as a single class,
          the Corporation may not:

                              (i)  amend  the Certificate  of Incorporation
                    so as have an adverse effect the voting powers or other
                    rights or preferences of shares of the Preferred Stock;
                    or

                              (ii)  authorize, issue or create any class of
                    capital stock that is pari passu with or senior with
                                          ---- -----
                    respect  to  dividends  or  liquidation  rights  to the
                    Preferred  Stock.   Notwithstanding the  foregoing, the
                    Corporation may amend  the Certificate of Incorporation
                    without prior notice to or consent of the Holder or the
                    holders  of  the  Funding  Preferred  Securities,  when
                    authorized by  the Board of Directors, if (a) the Board
                    of  Directors determines  that  such  action would  not
                    materially and  adversely  affect  the  rights  of  the
                    Holder  or  any   holder  of   the  Funding   Preferred
                    Securities  and  (b)  the Corporation  delivers  to the
                    Holder a  legal opinion  of independent counsel  to the
                    effect that  the requirements  of clause (a)  have been
                    satisfied.

                    11.  EXCLUSIVITY.  Except as expressly set forth herein,
                         -----------
          the holders of  the Preferred  Stock shall have  no rights  other
          than those provided by law.

                    "RESOLVED FURTHER,  that, before the  Corporation shall
          issue any shares of the  Preferred Stock, a certificate  pursuant
          to Section 151 of  the General  Corporation Law of  the State  of
          Delaware  shall   be  made,  executed,  acknowledged,  filed  and
          recorded in  accordance with  the provisions of  Sections 103 and
          151  thereof,  and the  proper  officers of  the  Corporation are
          hereby  authorized and directed to  do all acts  and things which
          may be  necessary or proper in their opinion to carry into effect
          the purposes and intent of this and the foregoing resolutions."

               Re:  Registration Statement on Form S-3
                    ----------------------------------

          Ladies and Gentlemen:

                    We have acted as counsel to ICG Communications, Inc., a
          Delaware corporation  ("ICG"), and  ICG Funding, LLC,  a Delaware
          limited liability company ("Funding," and, together with ICG, the
          "Registrants") in connection with the preparation and filing with
          the Securities and Exchange  Commission (the "Commission") of the
          above-referenced   Registration  Statement   on  Form   S-3  (the
          "Registration Statement")  under the  Securities Act of  1933, as
          amended  (the "Act"), relating to  the resale (i)  by the holders
          named  therein  of  up  to  an  aggregate  of  2,645,000  6  3/4%
          Exchangeable  Limited Liability Company Preferred Securities, $50
          liquidation  preference per  Preferred  Security (the  "Preferred
          Securities), of Funding,  (ii) of 4,786,680 shares of  ICG common
          stock, par value  $.01 per share  (the "Common Stock"),  issuable
          upon exchange  of the Preferred Securities  (the "Exchange Common
          Shares") and (iii) by  Funding of up  to an aggregate of  200,000
          shares  of  Common  Stock   (the  "Distribution  Shares").    The
          Preferred Securities are fully and  unconditionally guaranteed by
          ICG  (the "Guarantee")  as  set forth  in  the Prospectus,  which
          constitutes part of the Registration Statement.  The Registration
          Statement also registers the Guarantee. 

                    In   connection   therewith,  we   have   examined  the
          Certificate of Incorporation and  the By-Laws of ICG, resolutions
          of  the Board of Directors of ICG and the Registration Statement.
          We  also have  examined  the  Certificate  of Formation  and  the
          Amended  and  Restated  Limited  Liability  Company  Agreement of
          Funding, and the written  action of the Manager  of Funding.   In
          addition, we have made such inquiries and have examined originals
          or copies of  other instruments  as we have  deemed necessary  or
          appropriate for the  purpose of  this opinion.   For purposes  of
          such  examination,  we  have   assumed  the  genuineness  of  all
          signatures on and the authenticity  of all documents submitted to
          us  as  originals, and  the conformity  to  the originals  of all
          documents submitted to us as certified or photostatic copies.

                    Based upon  the foregoing,  we are  of the  opinion (i)
          that the Preferred Securities  are validly issued and  fully paid
          preferred  limited liability company  interests of  Funding, (ii)
          that the Distribution Shares, and when issued in accordance with
          the authorization, will be validly issued, fully  paid and  non-
          assessable shares  of common  stock  of ICG, (iii) the Exchange 
          Common Shares,  when issued in accordance with the procedures set
          forth in  the  Prospectus, will  be  validly issued, fully paid 
          and non-assessable shares of Common Stock  and (iv) that  the 
          Guarantee has been duly authorized, legally issued and constitutes
          the valid and binding obligation of ICG.

                    We  hereby consent  to  the filing  of this  opinion as
          Exhibit 5.1 to  the Registration  Statement and to  the reference
          therein to our firm under the caption "Legal Matters."  In giving
          the foregoing consent, we do not thereby admit that we are in the
          category of persons whose consent is required  under Section 7 of
          the  Act   or  the  rules  and  regulations   of  the  Commission
          promulgated thereunder.

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


          Ladies and Gentlemen:

                    Reference is made to the prospectus, (the
          "Prospectus"), which constitutes part of the registration
          statement on Form S-3 ("Registration Statement"), to be filed by
          ICG Communications, Inc. and ICG Funding, LLC ("Funding") with
          the Securities and Exchange Commission on or about the date
          hereof pursuant to the Securities Act of 1933, as amended, for
          the registration of, among other things, Exchangeable Limited
          Liability Company Preferred Securities ("Preferred Securities")
          of Funding.

                    We are of the opinion that the statements set forth
          under the caption "Certain United States Federal Income Tax
          Consequences" in the Prospectus constitute an accurate
          description, in general terms, of certain United States federal
          income tax considerations that may be relevant to the prospective
          purchasers of the Preferred Securities.

                    We hereby consent to the filing of this opinion as an
          exhibit to the Registration Statement and to the references to us
          in the Prospectus under the caption "Certain United States
          Federal Income Tax Consequences.
