(1)  NATURE OF BUSINESS AND REFERENCE TO OTHER REPORTS

         ICG Communications, Inc. ("ICG"), a Delaware corporation, was
         incorporated on April 11, 1996, for the purpose of becoming the new
         publicly-traded U.S. parent company of ICG Holdings (Canada), Inc.
         ("Holdings-Canada"), a Canadian federal corporation (formerly known as
         IntelCom Group Inc.), ICG Holdings, Inc. ("Holdings"), a Colorado
         corporation (formerly known as IntelCom Group (U.S.A), Inc.), and its
         subsidiaries (collectively, the "Company"). The Company's principal
         business activity is telecommunications services, including Telecom
         Services, Network Services and Satellite Services. Telecom Services
         consists of the Company's competitive local exchange carrier operations
         which provide services to long distance carriers and resellers, as well
         as business end users. Network Services 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 other large businesses and
         telecommunications companies. Satellite Services provides satellite
         voice and data services to major cruise ship lines, the commercial
         shipping industry, yachts, the U.S. Navy and offshore oil platforms.
         The Company has been considering the disposition of its Satellite
         Services operations for some time to better focus on its core Telecom
         Services unit, although it has not approved or adopted a formal plan
         for such disposition.

     (a) REFERENCE TO ANNUAL AND TRANSITION REPORTS

         These financial statements should be read in conjunction with the
         Annual Report on Form 10-K for the year ended September 30, 1996 and
         the Transition Report on Form 10-K for the three months ended December
         31, 1996, as certain information and note disclosures normally included
         in financial statements prepared in accordance with generally accepted
         accounting principles have been condensed or omitted pursuant to the
         rules and regulations of the United States Securities and Exchange
         Commission. The interim financial statements reflect all adjustments
         which are, in the opinion of management, necessary for a fair
         presentation of financial position, results of operations and cash
         flows as of and for the interim periods presented. Such adjustments are
         of a normal recurring nature. Operating results for the nine months
         ended September 30, 1997 are not necessarily indicative of the results
         that may be expected for the year ending December 31, 1997.

     (b) RECLASSIFICATIONS

         Certain 1996 amounts have been reclassified to conform with the 1997
         presentation.

(2)  BUSINESS COMBINATIONS

     In October 1997, the Company purchased approximately 91% of the capital
     stock of Communications Buying Group, Inc. ("CBG"), an Ohio based local
     exchange and Centrex reseller.  The remaining approximately 9% will be
     purchased on or before March 24, 1998, pursuant to the terms of the
     purchase agreement governing the CBG aquisition.  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, the
     Company sold 687,221 shares of common stock for approximately $16.0 million
     to certain shareholders of CBG.  The Company will account for the
     acquisition under the purchase method of accounting.

(2)   BUSINESS COMBINATIONS (CONTINUED)

      In October 1997, the Company announced that it had signed an agreement and
      plan of merger with NETCOM On-Line Communication Services, Inc.
      ("NETCOM"), a provider of Internet connectivity and Web-hosting services
      located in San Jose, California.  On the effective merger date, a
      subsidiary of the Company will be merged with and into NETCOM and each
      share of NETCOM will constitute the right to receive a designated number
      of shares of ICG common stock.  The Company expects to issue approximately
      $283.5 million in common stock to complete the merger, based on the
      closing price of ICG common stock on the date immediately preceding the
      merger announcement.  Subject to the approval of the shareholders of ICG
      and NETCOM and the satisfaction of certain other conditions, the Company
      anticipates the merger to close during the first quarter of 1998.  The
      Company will account for the business combination under the pooling-of-
      interests method of accounting.  In the event that ICG terminates or
      prevents the merger, under certain circumstances, the Company would be
      required to pay NETCOM a termination fee of approximately $11.3 million.

        Exchangeable Preferred Stock Mandatorily Redeemable 2008 (the "14%
        Preferred Stock") for gross proceeds of $99.9 million and $100.0
        million, respectively.  Net proceeds from the private placement, after
        costs of approximately $7.5 million, were approximately $192.4 million.

        The 11 5/8% Notes are unsecured senior obligations of Holdings
        (guaranteed by ICG) that mature on March 15, 2007, at a maturity value
        of $176.0 million.  Interest will accrue at 11 5/8% per annum beginning
        March 15, 2002, and is payable each March 15 and September 15,
        commencing September 15, 2002.   The 11 5/8% Notes were originally
        recorded at approximately $99.9 million.  The discount on the 11 5/8%
        Notes and the debt issuance costs are being accreted over ten years
        until maturity at March 15, 2007.

        The accretion of the discount and debt issuance costs is included in
        interest expense in the accompanying consolidated financial statements.
        The indenture for the 11 5/8% Notes contains certain covenants which
        provide for limitations on indebtedness, dividends, asset sales and
        certain other transactions and effectively prohibits the payment of
        interest and dividends.

        The 14% Preferred Stock consists of 100,000 shares of exchangeable
        preferred stock of Holdings that bear a cumulative dividend at the rate
        of 14% per annum.  The dividend is payable quarterly in arrears each
        March 15, June 15, September 15, and December 15, commencing June 15,
        1997.  Through March 15, 2002, the dividend is payable at the option of
        Holdings in cash or additional shares of 14% Preferred Stock.  Holdings
        may exchange the 14% Preferred Stock into 14% Senior Subordinated
        Exchange Debentures at any time after the exchange is permitted by
        certain indenture restrictions.  The 14% Preferred Stock is subject to
        mandatory redemption on March 15, 2008.

    (b) PRIVATE PLACEMENT OF 6 3/4% PREFERRED SECURITIES
                                        
        On September 24, 1997, a new subsidiary of the Company, ICG Funding, LLC
        ("Funding") completed a private placement of 6 3/4% Exchangeable Limited
        Liability Company Preferred Securities Mandatorily Redeemable 2009 (the
        "6 3/4% Preferred Securities") for gross proceeds of $115.0 million.
        Net proceeds from the private placement, after underwriting costs, were
        approximately $111.6 million.  Included in restricted cash at September
        30, 1997 is $22.2 million of proceeds which are designated for the
        payment of cash dividends on the 6 3/4% Preferred Securities through
        November 15, 2000.  The remaining proceeds have been invested in
        government securities and are included in short-term investments
        available for sale at September 30, 1997.

        The 6 3/4% Preferred Securities consist of 2,300,000 exchangeable
        preferred securities of Funding that bear a cumulative dividend at the
        rate of 6 3/4% per annum.  The dividend is paid quarterly in arrears
        each February 15, May 15, August 15 and November 15, commencing November
        15, 1997.  The dividend is payable in cash through November 15, 2000,
        and in cash or shares of ICG common stock, at the option of Funding,
        thereafter.  The 6 3/4% Preferred Securities are exchangeable, at the
        option of the holder, at any time prior to November 15, 2009 into shares
        of ICG common stock at a rate of 2.0812 shares of ICG common stock per
        preferred security, or $24.025 per share.  Funding may, at its option,
        redeem the 6 3/4% Preferred Securities at any time on or after November
        18, 2000.  Prior to that time, Funding may redeem the 6 3/4% Preferred
        Securities if the current market value of ICG common stock equals or
        exceeds the exchange price, for at least 20 days of any 30-day trading
        period, by 170% prior to November 16, 1998; 160% from November 16, 1998
        through November 15, 1999; and 150% from

        Securities are subject to mandatory redemption on November 15, 2009.

        On  October  3,  1997,  the securities  underwriter  exercised  its
        option to purchase an additional 15% of 6 3/4% Preferred Securities. Net

    (b) LOSS PER SHARE

        Loss per share is calculated by dividing the net loss by the weighted
        average number of shares outstanding.  Weighted average number of shares
        outstanding represents Holdings-Canada common shares outstanding for the
        period from January 1, 1996 through August 2, 1996 and ICG Common Stock
        and Holdings-Canada Class A common shares (not owned by ICG) outstanding
        for the periods subsequent to August 5, 1996.  Common stock equivalents,
        which include options, warrants, convertible subordinated notes and
        exchangeable preferred securities, are not included in the loss per
        share calculation as their effect is anti-dilutive.
                                        
(5)  COMMITMENTS AND CONTINGENCIES

    (a) NETWORK CONSTRUCTION

        In March 1996, the Company and Southern California Edison Company
        ("SCE") jointly entered into a 25-year agreement under which the Company
        will license 1,258 miles of fiber optic cable in Southern California,
        and can install up to 500 additional miles of fiber optic cable. This
        network, which

(5) COMMITMENTS AND CONTINGENCIES (CONTINUED)

       will be maintained and operated primarily by the Company, stretches from
       Los Angeles to southern Orange County.  Under the terms of this
       agreement, SCE is entitled to receive an annual fee for ten years,
       certain fixed quarterly payments, a quarterly payment equal to a
       percentage of certain network revenue, and certain other installation and
       fiber connection fees. The aggregate fixed payments remaining under the
       agreement totaled approximately $145.1 million at September 30, 1997.
       The agreement has been accounted for as a capital lease in the
       accompanying consolidated balance sheets.

       In March 1996, the Company entered into a long-term agreement with a
       subsidiary of The Southern Company ("Southern") and Alabama Power
       Company ("Alabama Power") for the right to use 22 miles of existing
       fiber and 122 miles of additional Alabama Power rights of way and
       facilities to reach the three major business centers in Birmingham.
       Southern will, in conjunction with the Company, construct the network
       and provide maintenance services with respect to the fiber installed.
       Southern also will provide consulting services to the Company relating
       to the build-out of the network and potential enhancements to the
       Company's products and services.  Under the agreement, the Company is
       required to pay Southern a quarterly fee based on specified percentages
       of the Company's revenue for services provided through this network.
       The Company's estimated costs to complete the network are approximately
       $0.3 million. Network construction is expected to be completed in the
       fourth quarter of 1997.

       In May 1997, the Company entered into a second long-term agreement with
       Southern that will permit the Company to construct a 100-mile fiber optic
       network in the Atlanta metropolitan area. The Company paid $5.5 million
       upon execution of the agreement and is responsible for reimbursement to
       Southern for costs of network design, construction, installation,
       maintenance and repair. Additionally, the Company is also required to pay
       Southern a quarterly fee based on specified percentages of the Company's
       revenue derived from services provided over this network. Network
       construction on the initial build is expected to be completed in the
       first half of 1998. The Company estimates costs to complete the network
       to be approximately $9.0 million.

       In January 1997, the Company announced a strategic alliance with Central
       and Southwest Corporation ("CSW"), named CSW/ICG ChoiceCom, L.P., which
       is expected to develop and market telecommunications services in certain
       cities in Texas. CSW holds 100% of the partnership 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 option, CSW will have the right to sell 51% or 100% of the
       partnership interest in ChoiceCom to the Company. The price that the
       Company would pay for an ownership interest in ChoiceCom would be
       calculated pursuant to a formula set forth in the strategic alliance
       documents. Additionally, the Company has committed to loan $15.0 million
       to ChoiceCom over the near term, of which the Company has advanced
       approximately $6.4 million as of September 30, 1997.

       In June 1997, the Company entered into an indefeasible right of use
       ("IRU") agreement with Qwest Communications Corporation ("Qwest") for
       approximately 1,800 miles of fiber optic network and additional broadband
       capacity in California, Colorado, Ohio and the Southeast. Network
       construction is ongoing and is expected to be completed by December 1998.
       The Company is responsible for payment on the construction as segments of
       the network are completed and has incurred approximately $4.4 million as
       of September 30, 1997, with total costs anticipated to be approximately
       $45.0 million. Additionally, the Company has committed to purchase $6.0
       million in network capacity from Qwest prior to the end of 1998.

       In November 1995, the Company signed an agreement with City Public
       Service of San Antonio ("CPS") to license excess fiber optic facilities
       on a new 300-mile fiber network being built by the municipally

          owned electric and gas utility  to provide for its communications
          needs in  the greater  metropolitan area. Pursuant to this agreement,
          the Company provided a $12.0 million irrevocable letter of credit,
          secured by cash collateral, for the Company's portion of the
          construction costs.  In August 1997, the Company and CPS signed an
          agreement to cancel all terms of the November 1995 contract and all
          cash collateral was refunded to the Company.  All legal proceedings
          associated with this agreement have been withdrawn as a result of the
          agreement to cancel the November 1995 contract.

     (b)  COMPANY HEADQUARTERS

          The Company has acquired property for its new headquarters and has
          commenced construction of an office building that the Company expects
          will accommodate most of the Company's Colorado operations. The total
          cost of the project is expected to be approximately $44.0 million, of
          which $16.6 million has been incurred as of September 30, 1997 and is
          included in construction in progress. The Company has signed a letter
          of intent to sell the completed building to a third party and lease
          back the office space under a long-term operating lease. A final
          agreement is expected to be reached in the near future. The Company
          anticipates that the building will be completed near the end of 1997.

     (c)  PURCHASE AND OTHER COMMITMENTS

          The Company is obligated to purchase, at fair market value, all of the
          shares of Maritime Telecommunications Network, Inc. ("MTN"), a 64%
          owned subsidiary of the Company, that are owned by the minority
          shareholders, upon demand of the minority shareholders, if a
          transaction has not been effected which converts the minority shares
          into publicly traded securities or cash by January 3, 1998.

          The Company has entered into various equipment purchase agreements
          with certain of its vendors. Under these agreements, if the Company
          does not meet a minimum purchase level in any given year, the vendor
          may discontinue for that year certain discounts, allowances and
          incentives otherwise provided to the Company. In addition, the
          agreements may be terminated by either the Company or the vendor upon
          prior written notice. Additionally, the Company has entered into
          certain commitments to purchase capital assets with an aggregate
          purchase price of approximately $15.5 million at September 30, 1997.

     (d)  LITIGATION

          On April 4, 1997, certain shareholders of the Company's majority owned
          subsidiary, Zycom Corporation ("Zycom"), an Alberta, Canada
          corporation, filed a shareholder derivative suit and class action
          complaint for unspecified damages, purportedly on behalf of all of the
          minority shareholders of Zycom, in the District Court of Harris
          County, Texas (Cause No. 97-17777) against the Company, Zycom and
          certain of their subsidiaries.  This complaint alleges that the
          Company and certain of its subsidiaries breached certain duties owed
          to the plaintiffs.  The Company is vigorously defending the claims.
          While it is not possible to predict the outcome of this litigation,
          management believes these proceedings will not have a material adverse
          effect on the Company's financial condition, results of operations or
          cash flows.
 
          The Company is a party to certain other litigation which has arisen in
          the ordinary course of business.  In the opinion of management, the
          ultimate resolution of these matters will not have a significant
          effect on the Company's financial condition, results of operations or
          cash flows.

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
         -----------------------------------------------------------------------
         OF OPERATIONS
         -------------

     The following discussion includes certain forward-looking statements which
are affected by important factors including, but not limited to, 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 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.  The results for the three months and nine months
ended September 30, 1996 and 1997 have been derived from the Company's unaudited
Consolidated Financial Statements included elsewhere herein.  The Company
changed its fiscal year end to December 31 from September 30, effective January
1, 1997.  All dollar amounts are in U.S. dollars.

COMPANY OVERVIEW

     The Company provides Telecom Services, Network Services and Satellite
Services.  Telecom Services consist primarily of the Company's competitive local
exchange carrier ("CLEC") operations.  CLECs seek to provide an alternative to
the incumbent local exchange carriers ("ILECs") for a full range of
telecommunications services.  The Company is one of the largest providers of
competitive local telephone services in the United States, based on estimates of
the industry's 1996 revenue.  As a CLEC, the Company operates networks in four
regional clusters covering major metropolitan statistical areas in California,
Colorado, Ohio and the Southeast.  Network Services consist of information
technology services and selected networking products, focusing on network
design, installation, maintenance and support. Satellite Services consist of
maritime and international satellite transmission services and provide private
data networks utilizing VSATs.  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.  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 Company's rapid growth is the result of the initial installation,
acquisition and subsequent expansion of its fiber optic networks and the
expansion of its communication service offerings.

     Prior to fiscal 1996, the majority of the Company's revenue had been
derived from Network Services.  However, the Company's Network Services revenue
(as well as Satellite Service revenue) will continue to represent a diminishing
percentage of the Company's consolidated revenue as the Company continues to
emphasize its core Telecom Services.  In March 1996, the Company completed the
sale of four of its teleports which were used in the Company's Satellite
Services operations.

     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
competitive 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.  In addition, the Company's operating networks have grown
from 323 fiber route miles at the end of fiscal 1994 to 3,021 fiber route miles
at September 30, 1997.  The Company has 18 operating high capacity digital voice
switches and 15 data communications switches, and plans to install additional
switches as demand warrants.  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.  To facilitate
the expansion of its services, the Company has entered into agreements with
Lucent Technologies, Inc., Northern Telecom, Inc. and Cascade Communications,
Inc. to purchase a full range of switching systems, fiber optic cable, network
electronics, software and services.

     The Company will continue to expand its network through construction,
leased facilities, strategic joint ventures and potentially through
acquisitions. For example, in October 1997, the Company announced that it had
signed an agreement and plan of merger with NETCOM, located in San Jose,
California.  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

                                       17
<PAGE>
 
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 and thus, upon the closing of the merger, the Company's financial
statements will be restated to reflect the operations of NETCOM and the Company
on a combined basis for all historical periods. Subject to the approval of the
shareholders of ICG and NETCOM and satisfaction of certain other conditions, the
Company anticipates the merger to close during the first quarter of 1998. Also
in October 1997, the Company purchased approximately 91% of the capital stock of
CBG, an Ohio based local exchange and Centrex reseller. CBG 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, the
ILEC in the markets it serves. Further, for the calendar years 1995 and 1996 and
the nine months ended September 30, 1997, CBG's revenue was approximately $15.4
million, $21.4 million and $24.1 million, respectively, and EBITDA losses were
approximately $(1.3) million, $(1.0) million and $(1.3) million, respectively.
Pursuant to the terms of the purchase agreement governing the acquisition of
CBG, the Company will purchase the remaining 9% interest in CBG on or before
March 24, 1998. The Company previously 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 addition, the Company is expanding
its geographic focus to include Texas (and may also expand to Arkansas,
Louisiana and Oklahoma) through its strategic alliance with CSW that will
develop and market telecommunications services, including local service, in
these markets. In June 1997, the Company entered into an IRU agreement with
Qwest 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 communications services in and between the Company's markets.
 
     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.  The Company
has experienced declining 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 and increasing
price competition for the foreseeable future.
 
     In conjunction with the increase in its service offerings, the Company will
need to spend significant amounts on sales, marketing, customer service,
engineering and support personnel prior to the generation of appreciable
revenue.  This will have an adverse effect on operating margins until such time
as sufficient volumes of customers' telecommunications traffic are attained.  As
the Company's customer base grows, the Company anticipates that operating
margins will improve as incremental revenue will exceed incremental operating
expenses.  The preceding forward-looking statement is dependent upon the
successful implementation of the Company's local dial tone, data and long
distance services strategy, 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.

     Currently, the Company is experiencing negative operating margins from its
switched services while its networks are in the development and construction
phases and while the Company relies on ILEC networks to carry a significant
portion of its 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 de-emphasizes its wholesale switched
services. In addition, the Company believes that the unbundling of ILEC services
and the implementation of local telephone number portability, which are mandated
by the Telecommunications Act, will reduce the Company's costs of providing
switched services and facilitate the marketing of local and other services.
 
     The Company believes that the provisions of the Telecommunications Act,
including the opening of the local telephone services market to competition,
will facilitate the Company's plan to provide a full array of local, long
distance and data communications services. In order to fully implement its
strategy, the Company must make significant capital expenditures to provide
additional switching capacity, network infrastructure and electronic components.
The Company must also make significant investments and expenditures to develop,
train and manage its marketing and sales personnel.  The Company has limited
experience providing such services and there can be no assurance that the
Company will be successful.

     The continued development, construction and expansion of the Company's
business requires significant capital, a large portion of which is expended
before related revenue is generated. The Company has experienced, and expects to
continue to experience, negative cash flow and significant losses while it
expands its operations to provide a wide range of telecommunications services
and establishes a sufficient revenue-generating customer base. There can be no
assurance that the Company will be able to establish or retain such a customer
base.

(1)  EBITDA consists of revenue less operating costs and selling, general and
     administrative expenses. EBITDA is provided because it is a measure
     commonly used in the telecommunications industry. It is presented to
     enhance an understanding of the Company's operating results and is not
     intended to represent cash flows or results of operations in accordance
     with generally accepted accounting principles ("GAAP") for the periods
     indicated. Net cash flows from operating, investing and financing
     activities as determined using GAAP are also presented in Other Data. See
     the Company's Consolidated Financial Statements contained elsewhere in this
     Quarterly Report.

(2)  Capital expenditures include assets acquired under capital leases.

(3)  Amounts presented are for three-month periods ended, or as of the end of,
     the period presented.

(4)  Access lines in service at September 30, 1997 includes 38,223 lines which
     are provisioned through the Company's switch and 12,328 lines which are
     provisioned through resale and other agreements with various local exchange
     carriers. Resale lines typically generate lower margins and are used
     primarily to obtain customers. Although the Company plans to migrate lines
     from resale to higher margin on-switch lines, there are no assurances that
     it will be successful in executing this strategy.

(5)  Hybrid buildings connected represent buildings connected to the Company's
     network via another carrier's facilities.

(6)  Customer circuits in service are measured in voice grade equivalents
     ("VGEs").

(7)  Fiber route miles refers to the number of miles of fiber optic cable,
     including leased fiber. As of September 30, 1997, the Company had 3,021
     fiber route miles, of which 171 fiber route miles were leased under
     operating leases. Fiber route miles under construction represents fiber
     under construction which is expected to be operational within six months.

(8)  Fiber strand miles refers to the number of fiber route miles, including
     leased fiber, along a telecommunications path multiplied by the number of
     fiber strands along that path. As of September 30, 1997, the Company had
     109,510 fiber strand miles, of which 15,165 fiber strand miles were leased
     under operating leases. Fiber strand miles under construction represents
     fiber under construction which is expected to be operational within six
     months.

(9)  Wireless miles represents the total distance of the digital microwave paths
     between Company transmitters which are used in the Company's networks.

(10) C-Band installations service cruise ships, U.S. Navy vessels and offshore
     oil platform installations.

(11) L-Band installations service smaller maritime installations, and both
     mobile and fixed land-based units.


THREE MONTHS ENDED SEPTEMBER 30, 1997 COMPARED TO THREE MONTHS ENDED SEPTEMBER
30, 1996

     Revenue.  Revenue for the three months ended September 30, 1997 increased
     -------
$14.6 million, or 28%, from the three months ended September 30, 1996. Telecom
Services revenue increased 36% to $43.7 million due to an increase in network
usage for both switched and special access services, offset in part by a decline
in average unit pricing. Switched services revenue increased from $13.2 million
(41% of Telecom Services revenue) for the three months ended September 30, 1996
to $22.2 million (51% of Telecom Services revenue) for the three months ended
September 30, 1997.  Switched access (terminating long distance) represented
approximately 86% of the Company's switched services revenue component for the
three months ended September 30, 1997, compared to 100% for the three months
ended September 30, 1997.  The Company expects that switched access services
will represent a diminishing percentage of switched services revenue in the
future as revenue from local dial tone services increases and the Company de-
emphasizes its wholesale switched services.  Special access revenue increased
from $10.3 million (32% of Telecom Services revenue) for the three months ended
September 30, 1996 to $14.4 million (33% of Telecom Services revenue) for the
three months ended September 30, 1997.  Also included in Telecom Services
revenue for the three months ended September 30, 1997 is $7.1 million generated
by Zycom, compared to $8.6 million for the same period in 1996.  Substantially
all of the decrease in Zycom revenue for the three months ended September 30,
1997 as compared to the same period in 1996 relates to a decrease in switched
minutes and per minute rates as a result of a changing customer 

                                       20

base. At September 30, 1997, the Company had 50,551 access lines in service
compared to zero at September 30, 1996. Special access network usage reflected
in voice grade equivalents ("VGEs") increased 60% from approximately 631,000
VGEs at September 30, 1996, to approximately 1,007,000 VGEs at September 30,
1997. At September 30, 1997, the Company had 2,316 buildings connected to its
networks compared to 2,067 buildings connected at September 30, 1996.
Additionally, switched minutes of use increased 40% from 563 million minutes
during the three months ended September 30, 1996 to 788 million minutes during
the three months ended September 30, 1997. Revenue from long distance and data
services did not generate a material portion of total revenue during either
period. Network Services revenue increased 4% to $16.4 million for the three
months ended September 30, 1997 as compared to $15.7 million for the three
months ended September 30, 1996 due to additional projects from new and existing
customers. Satellite Services revenue increased $2.4 million, or 47%, to $7.6
million for the three months ended September 30, 1997. This increase is
primarily due to the operations of MarineSat Communications Network, Inc.
(formerly known as Maritime Cellular Tele-Network, Inc. ("MCN")), a wholly owned
subsidiary of the Company acquired in March 1996, which comprised $1.6 million
of total Satellite Services revenue for the three months ended September 30,
1997 compared to $0.3 million during the same period in 1996. The remaining
increase can be attributed to the general growth of Maritime Telecommunications
Network, Inc. ("MTN") and its increased sales of C-Band equipment to offshore
oil and gas customers.
 
     Operating costs.  Total operating costs for the three months ended
     ---------------
September 30, 1997 increased $15.1 million, or 34% from the three months ended
September 30, 1996.  Telecom Services operating costs increased from $29.3
million, or 91% of Telecom Services revenue, for the three months ended
September 30, 1996, to $42.3 million, or 97% of Telecom Services revenue, for
the three months ended September 30, 1997.  Telecom Services operating costs
consist of payments to ILECs for the use of network facilities to support
special and switched access services, network operating costs, right of way fees
and other costs.  The increase in operating costs in absolute dollars is
attributable to the increase in switched access services and the addition of
engineering and operations personnel dedicated to the development of local
exchange services.  The increase in operating costs as a percentage of total
revenue is due primarily to the increase in switched access services revenue,
which generates negative margins as a result of the higher costs associated with
utilizing ILEC network facilities, and the investment in the development of
local exchange services without the benefit of corresponding revenue in the same
period.  The Company expects that its Telecom Services ratio of operating costs
to revenue will begin to improve as the Company provides a greater volume of
higher margin services, principally local exchange services, carries more
traffic on its own facilities rather than the ILEC facilities, and obtains the
right to use unbundled ILEC facilities on satisfactory terms, any or all of
which may not occur.  Network Services operating costs as a percentage of
Network Services revenue was 80% for both the three-month periods ended
September 30, 1996 and 1997.  Network Services operating costs include the cost
of equipment sold, direct hourly labor and other indirect project costs.
Satellite Services operating costs increased to $4.2 million for the three
months ended September 30, 1997, from $2.7 million for the three months ended
September 30, 1996.  Satellite Services operating costs as a percentage of
Satellite Services revenue also increased from 53% for the three months ended
September 30, 1996 to 55% for the three months ended September 30, 1997.   This
increase is due to an increase in MCN's sales in the current three-month period
as well as the increased volume of equipment sales, both of which provide lower
margins than other maritime services. Satellite Services operating costs consist
primarily of transponder lease costs and the cost of equipment sold.
 
     Selling, general and administrative expenses.  Selling, general and
     --------------------------------------------
administrative ("SG&A") expenses for the three months ended September 30, 1997
increased $18.3 million, or 86%, compared to the three months ended September
30, 1996. This increase was principally due to the continued rapid expansion of
the Company's Telecom Services networks and related significant additions to the
Company's management information systems, customer service, marketing and sales
staffs dedicated to the expansion of the Company's networks and implementation
of the Company's expanded services strategy, primarily the development of local
and long distance telephone services. SG&A expenses as a percentage of total
revenue increased from 40% for the three months ended September 30, 1996 to 59%
for the three months ended September 30, 1997.  There is typically a period of
higher administrative and marketing expense prior to the generation of
appreciable revenue from newly developed networks or services.  The Company
expects SG&A expenses for Telecom Services to increase slightly over the near
term as a result of hiring new staff to facilitate the marketing and development
of local dial tone, local toll, long distance and data transmission services.

     Depreciation and amortization.  Depreciation and amortization increased
     -----------------------------
$4.7 million, or 53%, for the three months ended September 30, 1997, compared to
the three months ended September 30, 1996, due to increased investment in
depreciable assets resulting from the continued expansion of the Company's
networks and services. The Company reports high levels of depreciation expense
relative to revenue during the early years of operation of a new

                                       21

network because the full cost of a network is depreciated using the straight-
line method despite the low rate of capacity utilization in the early stages of
network operation.
 
      Net loss on disposal of long-lived assets.  Net loss on disposal of long-
      -----------------------------------------
lived assets decreased from $2.2 million for the three months ended September
30, 1996 to $1.2 million for the three months ended September 30, 1997.  Net
loss on disposal of long-lived assets for the three months ended September 30,
1996 includes the loss recorded on the sale of four of the Company's teleports
used in its Satellite Services operations ($0.2 million) as well as the loss
recorded on the disposal of other operating assets ($2.0 million).  For the
three months ended September 30, 1997, net loss on disposal of long-lived assets
primarily relates to losses recorded on the disposal of the Company's investment
in its Melbourne network.
 
     Provision for impairment of long-lived assets.  Provision for impairment of
     ---------------------------------------------
long-lived assets for the three months ended September 30, 1996 includes
valuation allowances for the amounts receivable for advances made to the Phoenix
network joint venture included in long-term note receivable ($5.8 million), the
investments in the Melbourne network ($2.7 million) and the Satellite Services
Mexico subsidiary ($0.1 million) and the note receivable from NovoComm, Inc.
($1.3 million).
 
     Interest expense.  Interest expense increased $5.5 million, from $23.3
     ----------------
million for the three months ended September 30, 1996, to $28.8 million for the
three months ended September 30, 1997, which included $27.1 million of non-cash
interest.  The increase in interest expense is due to the issuance of the 11
5/8% Notes in March 1997.  In addition, the Company's interest expense
increased, and will continue to increase, because the principal amount of its
indebtedness increases until Holdings' senior indebtedness begins to pay
interest in cash.

     Interest income.  Interest income decreased $1.5 million, from $6.9 million
     ---------------
for the three months ended September 30, 1996, to $5.4 million for the three
months ended September 30, 1997.  The decrease is attributable to the decrease
in the average balance of cash, cash equivalents and short-term investments
during the three months ended September 30, 1997.  The Company expects interest
income to continue to decrease over time as cash, cash equivalents and short-
term investments decline.
 
     Other, net.  Other, net fluctuated from $3.7 million net expense in the
     ----------
three months ended September 30, 1996 to $0.1 million net income for the three
months ended September 30, 1997.  Other expense recorded in the three-month
period ended September 30, 1996 consists primarily of the write-off of deferred
financing costs associated with the conversion or repayment of debt.  For the
three-month period ended September 30, 1997, other, net consists of
miscellaneous other income.

     Minority interest in share of losses, net of accretion and preferred
     --------------------------------------------------------------------
dividends on subsidiary preferred securities.  Minority interest in share of
--------------------------------------------
losses, net of accretion and preferred dividends on subsidiary preferred
securities increased $6.6 million, from $3.6 million for the three months ended
September 30, 1996 to $10.1 million for the three months ended September 30,
1997.  The increase is due primarily to the issuance of the 14% Preferred Stock
in March 1997.  Minority interest in share of losses, net of accretion and
preferred dividends on subsidiary preferred securities recorded during the
current three-month period consists of the accretion of issue costs ($0.1
million) and the accrual of the preferred security dividends ($10.2 million)
associated with the 14% Preferred Stock and the 14 1/4% Preferred Stock, offset
by minority interest in losses of subsidiaries of $0.2 million.

     Share of losses in joint venture and investment.  Effective October 1,
     -----------------------------------------------
1996, the Company sold its 50% interest in the Phoenix network joint venture.
As a result, no share of losses in joint venture was recorded during the three
months ended September 30, 1997, as compared to the $0.6 million loss recorded
during the comparable period in 1996.

     Net loss.  Net loss increased $22.2 million, or 39%, due to the increases
     --------
in operating costs, SG&A expenses, depreciation and amortization, interest
expense and minority interest in share of losses, net of accretion and preferred
dividends on subsidiary preferred stock noted above.

NINE MONTHS ENDED SEPTEMBER 30, 1997 COMPARED TO NINE MONTHS ENDED SEPTEMBER 30,
1996
 
     Revenue.  Revenue for the nine months ended September 30, 1997 increased
     -------
$61.9 million, or 46%, from the nine months ended September 30, 1996. Telecom
Services revenue increased 66% to $123.2 million due to an increase in network
usage for both switched and special access services, offset in part by a decline
in average unit pricing. Switched services revenue increased from $31.6 million
(43% of Telecom Services revenue) for the nine months ended 

                                       22
<PAGE>
 
September 30, 1996 to $61.7 million (50% of Telecom Services revenue) for the
nine months ended September 30, 1997. Switched access (terminating long
distance) revenue represented approximately 93% of the Company's switched
services revenue component for the nine months ended September 30, 1997,
compared to 100% for the nine months ended September 30, 1997. Special access
revenue increased from $28.5 million (39% of Telecom Services revenue) for the
nine months ended September 30, 1996 to $39.9 million (32% of Telecom Services
revenue) for the nine months ended September 30, 1997. Also included in Telecom
Services revenue for the nine months ended September 30, 1997 is $21.6 million
generated by Zycom, compared to $14.0 million for the same period in 1996. The
increase in Zycom revenue for the nine months ended September 30, 1997 as
compared to the same period in 1996 relates to changes in the classification of
certain operating costs as a result of the Company entering into long-term
contracts with its major customers. These costs were netted against revenue
during the 1996 period due to the uncertainty of renewal of short-term customer
contracts. At September 30, 1997, the Company had 50,551 access lines in service
compared to zero at September 30, 1996. Special access network usage reflected
in voice grade equivalents ("VGEs") increased 60% from approximately 631,000
VGEs at September 30, 1996, to approximately 1,007,000 VGEs at September 30,
1997. At September 30, 1997, the Company had 2,316 buildings connected to its
networks compared to 2,067 buildings connected at September 30, 1996.
Additionally, switched minutes of use increased 57% from 1.4 billion minutes
during the nine months ended September 30, 1996 to 2.2 billion minutes during
the nine months ended September 30, 1997. Revenue from long distance and data
services did not generate a material portion of total revenue during either
period. Network Services revenue increased 13% to $50.1 million for the nine
months ended September 30, 1997 as compared to $44.4 million for the nine months
ended September 30, 1996. The increase in Network Services revenue is due to
additional projects from new and existing customers. Satellite Services revenue
increased $7.2 million, or 47%, to $22.3 million for the nine months ended
September 30, 1997. This increase is primarily due to the operations of MCN,
which comprised $4.4 million of total Satellite Services revenue for the nine
months ended September 30, 1997 compared to $1.0 million during the same period
in 1996. The remaining increase can be attributed to the general growth of MTN
and its increased sales of C-Band equipment to offshore oil and gas customers.
 
     Operating costs.  Total operating costs for the nine months ended September
     ---------------
30, 1997 increased $70.9 million, or 66% from the nine months ended September
30, 1996.  Telecom Services operating costs increased from $66.8 million, or 90%
of Telecom Services revenue, for the nine months ended September 30, 1996, to
$126.2 million, or 103% of Telecom Services revenue, for the nine months ended
September 30, 1997. The increase in operating costs in absolute dollars is
attributable to the increase in switched access services and the addition of
engineering and operations personnel dedicated to the development of local
exchange services.  The increase in operating costs as a percentage of total
revenue is due primarily to the increase in switched access services revenue,
and the investment in the development of local exchange services without the
benefit of substantial corresponding revenue in the same period. Network
Services operating costs increased 18% to $40.6 million and increased as a
percentage of Network Services revenue from 75% for the nine months ended
September 30, 1996 to 81% for the nine months ended September 30, 1997.  The
increase is due to a substantially lower margin earned on equipment sales (which
constituted a larger portion of 1997 revenue) relative to other services and
certain indirect project costs included in operating costs during the nine
months ended September 30, 1997 which were treated as SG&A expenses during the
comparable period in 1996.  Satellite Services operating costs increased to
$12.2 million for the nine months ended September 30, 1997, from $7.1 million
for the nine months ended September 30, 1996. Satellite Services operating costs
as a percentage of Satellite Services revenue also increased from 47% for the
nine months ended September 30, 1996 to 55% for the nine months ended September
30, 1997.   This increase is due to an increase in MCN's sales in the current
nine-month period as well as the increased volume of equipment sales, both of
which provide lower margins than other maritime services.
 
     Selling, general and administrative expenses.  Selling, general and
     --------------------------------------------
administrative ("SG&A") expenses for the nine months ended September 30, 1997
increased $53.8 million, or 93%, compared to the nine months ended September 30,
1996. This increase was principally due to the continued rapid expansion of the
Company's Telecom Services networks and related significant additions to the
Company's management information systems, customer service, marketing and sales
staffs dedicated to the expansion of the Company's networks and implementation
of the Company's expanded services strategy, primarily the development of local
and long distance telephone services. SG&A expenses as a percentage of total
revenue increased from 44% for the nine months ended September 30, 1996 to 57%
for the nine months ended September 30, 1997.
 
     Depreciation and amortization.  Depreciation and amortization increased
     -----------------------------
$12.2 million, or 48%, for the nine months ended September 30, 1997, compared to
the nine months ended September 30, 1996, due to increased investment in
depreciable assets resulting from the continued expansion of the Company's
networks and services.

     Net loss on disposal of long-lived assets.  Net loss on disposal of long-
     -----------------------------------------
lived assets decreased from $4.1 million for the nine months ended September 30,
1996 to $1.0 million for the nine months ended September 30, 1997.  Net loss on
disposal of long-lived assets for the nine months ended September 30, 1996
includes the loss recorded on the sale of four of the Company's teleports used
in its Satellite Services operations ($1.1 million), the loss recorded on the
disposal of other operating assets ($2.6 million) and a write-down in an
investment ($0.4 million).  For the nine months ended September 30, 1997, net
loss on disposal of long-lived assets primarily relates to losses recorded on
the disposal of the Company's investment in its Melbourne network.
 
     Provision for impairment of long-lived assets.  Provision for impairment of
     ---------------------------------------------
long-lived assets for the nine months ended September 30, 1996 includes
valuation allowances for the amounts receivable for advances made to the Phoenix
network joint venture included in long-term note receivable ($5.8 million), the
investments in the Melbourne network ($2.7 million) and the Satellite Services
Mexico subsidiary ($0.1 million) and the note receivable from NovoComm, Inc.
($1.3 million).
 
     Interest expense.  Interest expense increased $11.8 million, from $70.5
     ----------------
million for the nine months ended September 30, 1996, to $82.3 million for the
nine months ended September 30, 1997, which included $77.0 million of non-cash
interest.  This increase was primarily attributable to an increase in long-term
debt, primarily the 11 5/8% Notes and the 12 1/2% Senior Discount Notes due 2006
("12 1/2% Notes") issued in March 1997 and April 1996, respectively.  In
addition, the Company's interest expense increased, and will continue to
increase, because the principal amount of its indebtedness increases until
Holdings' senior indebtedness begins to pay interest in cash.

     Interest income.  Interest income increased $1.7 million, from $15.6
     ---------------
million for the nine months ended September 30, 1996, to $17.3 million for the
nine months ended September 30, 1997.  The increase is attributable to the
increase in cash from the proceeds of the issuances of the 11 5/8% Notes and 14%
Preferred Stock in March 1997 and the 12 1/2% Notes and 14 1/4% Exchangeable
Preferred Stock Mandatorily Redeemable 2007 (the "14 1/4% Preferred Stock") in
April 1996.
 
     Other, net.  Other, net decreased from $3.9 million net expense in the nine
     ----------
months ended September 30, 1996 to $0.3 million net expense in the nine months
ended September 30, 1997.  Other expense recorded in the nine-month period ended
September 30, 1996 consists primarily of the write-off of deferred financing
costs associated with the conversion or repayment of debt and litigation
settlement costs.  For the nine-month period ended September 30, 1997, other,
net consists primarily of litigation settlement costs.

     Minority interest in share of losses, net of accretion and preferred
     --------------------------------------------------------------------
dividends on subsidiary preferred securities.  Minority interest in share of
--------------------------------------------
losses, net of accretion and preferred dividends on subsidiary preferred
securities increased $2.9 million, from $22.1 million for the nine months ended
September 30, 1996 to $25.0 million for the nine months ended September 30,
1997.  The increase is due primarily to the issuance of the 14 1/4% Preferred
Stock in April 1996 and the 14% Preferred Stock in March 1997.  Offsetting this
increase is $12.3 million recorded during the nine months ended September 30,
1996 for the excess of the redemption price over the carrying amount of the 12%
redeemable preferred stock of Holdings ("12% Redeemable Preferred Stock")
redeemed in April 1996.   Minority interest in share of losses, net of accretion
and preferred dividends on subsidiary preferred securities recorded during the
current nine-month period consists of the accretion of issue costs ($0.6
million) and the accrual of the preferred security dividends ($26.3 million)
associated with the 14% Preferred Stock and the 14 1/4% Preferred Stock, offset
by minority interest in losses of subsidiaries of $1.9 million.

     Share of losses in joint venture and investment.  Effective October 1,
     -----------------------------------------------
1996, the Company sold its 50% interest in the Phoenix network joint venture.
As a result, no share of losses in joint venture was recorded during the nine
months ended September 30, 1997, as compared to the $1.6 million loss recorded
during the comparable period in 1996.

     Net loss.  Net loss increased $74.9 million, or 50%, due to the increases
     --------
in operating costs, SG&A expenses, depreciation and amortization, interest
expense and minority interest in share of losses, net of accretion and preferred
dividends on subsidiary preferred stock noted above.

LIQUIDITY AND CAPITAL RESOURCES

     The Company's growth has been funded through a combination of equity, debt
and lease financing.  As of September 30, 1997, the Company had current assets
of $469.8 million, including $388.2 million of cash, cash equivalents and short-
term investments available for sale, which exceeded current liabilities of $93.0
million, providing 

                                       24
<PAGE>
 
working capital of $376.8 million. The Company invests excess funds in short-
term, interest-bearing investment-grade securities until such funds are used to
fund the capital investments and operating needs of the Company's business. The
Company's short-term investment objectives are safety, liquidity and yield, in
that order.

CASH USED BY OPERATING ACTIVITIES

     The Company's operating activities used $38.8 million and $71.2 million for
the nine months ended September 30, 1996 and 1997, respectively.  Cash used by
operations is primarily due to net losses, which are partially offset by non-
cash expenses, such as depreciation and amortization expense, deferred interest
expense, preferred dividends on subsidiary preferred stock and changes in
working capital items.

     The Company expects to continue to generate negative cash flow from
operating activities while it emphasizes development, construction and expansion
of its Telecom Services business.  Consequently, it does not anticipate that
cash provided by operations will be sufficient to fund operating activities, the
future expansion of existing networks or the construction and acquisition of new
networks in the near term.

CASH USED BY INVESTING ACTIVITIES

     Cash used by investing activities was $110.0 million and $304.5 million for
the nine months ended September 30, 1996 and 1997, respectively.  Cash used by
investing activities includes cash expended for the acquisition of property,
equipment and other assets, of $97.0 million and $204.2 million for the nine
months ended September 30, 1996 and 1997, respectively.  The Company will
continue to use cash in investing activities in 1997 and subsequent periods for
the construction of new networks and the expansion of existing networks.  The
Company acquired assets under capital leases of $54.9 million for the nine
months ended September 30, 1996, which consisted primarily of fiber optic
networks included in the Company's agreement with SCE.

CASH PROVIDED BY FINANCING ACTIVITIES

     Financing activities provided $368.6 million and $283.2 million in the nine
months ended September 30, 1996 and 1997, respectively.  Cash provided by
financing activities primarily includes cash received in connection with the
private placement of the 12 1/2% Notes and the 14 1/4% Preferred Stock in April
1996,  the 11 5/8% Notes and the 14% Preferred Stock in March 1997 and the 6
3/4% Preferred Securities in September 1997.  Historically, the funds to finance
the Company's business acquisitions, capital expenditures, working capital
requirements and operating losses have  been  obtained  through  public  and
private offerings of  Holdings-Canada  common shares,  the Senior Notes, units
consisting of senior notes and warrants, redeemable preferred stock, convertible
subordinated notes, convertible preferred shares of Holdings-Canada, capital
lease financings and various working capital sources, including credit
facilities.
 
     On March 11, 1997, Holdings completed a private placement of 11 5/8% Notes
and 100,000 shares of 14% Preferred Stock for net proceeds of approximately
$192.4 million.  The Company believes the net proceeds of the private placement
will improve its operating and financial flexibility over the near term because
(a) the 11 5/8% Notes do not require the payment of cash interest until 2002 and
(b) Holdings has the option to pay dividends on the 14% Preferred Stock in
additional shares of 14% Preferred Stock prior to 2002 and the Preferred Stock
is not mandatorily redeemable until 2008.
 
     The 11 5/8% Notes are unsecured senior obligations of Holdings (guaranteed
by ICG) that mature on March 15, 2007.  Interest will accrue at 11 5/8% per
annum beginning March 15, 2002, and is payable each March 15 and September 15,
commencing September 15, 2002.  Dividends on the 14% Preferred Stock are
cumulative at a rate of 14% per annum and are payable quarterly in arrears each
March 15, June 15, September 15 and December 15, commencing June 15, 1997.  The
14% Preferred Stock has a liquidation preference of $1,000 per share, plus
accrued and unpaid dividends, and is mandatorily redeemable in 2008.  The 14%
Preferred Stock is exchangeable, at the option of Holdings, into 14% senior
subordinated exchange debentures of Holdings due 2008, at any time after the
exchange is permitted under certain indenture restrictions.
 
     On September 24, 1997, Funding completed a private placement of 2,300,000 6
3/4% Preferred Securities for net proceeds, after underwriting costs, of
approximately $111.6 million.  Dividends on the 6 3/4% Preferred Securities are
payable quarterly in arrears each February 15, May 15, August 15, and November
15, commencing November 15, 1997.  The dividend is payable in cash through
November 15, 2000, and in cash or shares of ICG common stock, at the

                                       25
<PAGE>
 
option of Funding, thereafter. The 6 3/4% Preferred Securities have a
liquidation preference of $50 per security, plus accrued and unpaid dividends,
and are mandatorily redeemable in 2009. The 6 3/4% Preferred Securities are
exchangeable at any time prior to November 15, 2009 into shares of ICG common
stock at a rate of 2.0812 shares of ICG common stock per preferred security, or
$24.025 per share.
 
     As of September 30, 1997, an aggregate of approximately $72.6 million of
capitalized lease obligations and an aggregate accreted value of approximately
$859.9 million were outstanding under the 11 5/8% Notes, 12 1/2% Notes and the
13 1/2% Notes.  The 11 5/8% Notes require payments of interest to be made in
cash commencing on March 15, 2002 and mature on March 15, 2007.  The 12 1/2%
Notes require payments of interest to be made in cash commencing on November 1,
2001 and mature on May 1, 2006.  The 13 1/2% Notes require payments of interest
to be made in cash commencing on March 15, 2001 and mature on September 15,
2005.  The 6 3/4% Preferred Securities require payments of dividends to be made
in cash commencing November 15, 1997 through November 15, 2000.  In addition,
the 14% Preferred Stock and 14 1/4% Preferred Stock require payment of dividends
to be made in cash commencing June 15, 2002 and August 1, 2001, respectively.
As of September 30, 1997, the Company had $8.4 million of other indebtedness
outstanding. The Company may also have additional payment obligations prior to
such time, the amount of which cannot presently be determined. The Company's
cash on hand and amounts expected to be available through vendor financing
arrangements will provide sufficient funds necessary for the Company to expand
its Telecom Services business as currently planned and to fund its operating
deficits through 1997 and 1998. 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. With
respect to preferred securities and preferred stock currently outstanding, the
Company has cash dividend obligations of approximately $1.3 million in 1997,
$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. The Company's ability to do so will depend on, among
other things, its financial condition at the time, restrictions in the
instruments governing its indebtedness, and other factors, including market
conditions, beyond the control of the Company. 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 or make
payments of cash dividends on, or the mandatory redemption of, its preferred
securities and preferred stock, would be adversely affected.

CAPITAL EXPENDITURES

     The Company expects to continue to generate negative cash flow from
operating activities while it emphasizes development, construction and expansion
of its business and until the Company establishes a sufficient revenue-
generating customer base.  The Company's capital expenditures (including assets
acquired under capital leases) were $39.5 million and $71.6 million for the
three months ended September 30, 1996 and 1997, respectively, and $151.9 million
and $204.2 million for the nine months ended September 30, 1996 and 1997,
respectively.  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 during 1998.
To facilitate the expansion of its services and networks, the Company has
entered into equipment purchase agreements with various vendors under which the
Company must purchase a substantial amount of equipment and other assets,
including a full range of switching systems, fiber optic cable, network
electronics, software and services.  Actual capital expenditures will depend on
numerous factors, including certain factors beyond the Company's control. These
factors include the nature of future expansion and acquisition opportunities,
economic conditions, competition, regulatory developments and the availability
of equity, debt and lease financing.

GENERAL

     The Company's operations have required and will continue to require
significant capital expenditures for development, construction, expansion and
acquisition of telecommunications assets.  Significant amounts of capital are
required to be invested before revenue is generated, which results in initial
negative cash flows.  In addition to the Company's planned capital expenditures,
it has other cash commitments as described in the footnotes to the Company's
unaudited Consolidated Financial Statements for the nine months ended September
30, 1997 included elsewhere herein.

     In view of the anticipated negative cash flow from operating activities,
the continuing development of the Company's products and services, the expansion
of existing networks and the construction, leasing and licensing of new

                                       26
<PAGE>
 
networks, the Company will require additional amounts of cash in the future from
outside sources.  Management believes that the Company's cash on hand and
amounts expected to be available through vendor financing arrangements will
provide sufficient funds necessary for the Company to expand its Telecom
Services business as currently planned and to fund its operating deficits
through 1997 and 1998. Additional sources of cash may include public and private
equity and debt financings, sales of non-strategic assets, capitalized leases
and other financing arrangements. The Company may require additional amounts of
equity capital in the near term. In the past, the Company has been able to
secure sufficient amounts of financing to meet its capital expenditure needs.
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.

     The failure to obtain sufficient amounts of financing could result in the
delay or abandonment of some or all of the Company's development and expansion
plans, which could have a material adverse effect on the Company's business.  In
addition, the inability to fund operating deficits with the proceeds of
financings until the Company establishes a sufficient revenue generating
customer base could have a material adverse effect on the Company's liquidity.

NEW ACCOUNTING STANDARD

     In February 1997, the Financial Accounting Standards Board issued Statement
No. 128, "Earnings Per Share" ("SFAS 128") which revises the calculation and
presentation provisions of Accounting Principles Board Opinion 15 and related
interpretations.  SFAS 128 is effective for the Company's fiscal year ending
December 31, 1997 and retroactive application is required.  The Company believes
the adoption of SFAS 128 will have no effect on its reported loss per share.
