          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 consists of satellite
          voice,  data and video  services  provided to major cruise ship lines,
          the U.S.  Navy,  the  offshore  oil and gas  industry  and  integrated
          communications providers.

          On January  21,  1998,  the  Company  completed  a merger  with NETCOM
          On-Line Communication Services, Inc. ("NETCOM"). At the effective time
          of the merger, each outstanding share of NETCOM common stock, $.01 par
          value,  was  automatically  converted into shares of ICG common stock,
          $.01 par value ("ICG Common  Stock"),  at an exchange  ratio of 0.8628
          shares of ICG Common Stock per NETCOM common share. The Company issued
          approximately  10.2 million  shares of ICG Common Stock in  connection
          with the merger, valued at approximately $284.9 million on the date of
          the merger. The business combination was accounted for as a pooling of
          interests.  On February 17 and March 16, 1999,  the Company  completed
          the sales of the  operations of NETCOM (see note 3) and,  accordingly,
          the Company's  consolidated  financial  statements  prior to March 16,
          1999 reflect the operations and net assets of NETCOM as  discontinued.
          In conjunction with the sales, the legal name of the NETCOM subsidiary
          was changed to ICG NetAhead, Inc. ("NetAhead") (see note 3).

          On July 15, 1999,  the Company's  board of directors  adopted a formal
          plan to dispose of the Company's  investments in Network  Services and
          Satellite  Services  (see  note 3)  and,  accordingly,  the  Company's
          consolidated  financial  statements  reflect  the  operations  and net
          assets of Network Services and Satellite  Services as discontinued for
          all periods presented.

(2)      Significant Accounting Policies

         (a)   Basis of Presentation

               The Company's financial  statements should be read in conjunction
               with ICG's  Annual  Report on Form 10-K for the fiscal year ended
               December 31, 1998, 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.

(2)      Significant Accounting Policies (continued)

               Operating  results for the six months ended June 30, 1999 are not
               necessarily  indicative  of the results  that may be expected for
               the fiscal year ending December 31, 1999.

               All significant  intercompany accounts and transactions have been
               eliminated in consolidation.

         (b)   Net Loss Per Share

               Basic and  diluted net loss per share is  calculated  by dividing
               net loss by the weighted average number of shares of common stock
               outstanding.   Weighted  average  number  of  shares  outstanding
               represents ICG Common Stock  outstanding for the six months ended
               June 30, 1999 and combined  ICG Common Stock and  Holdings-Canada
               Class A common shares  outstanding  for the six months ended June
               30,  1998.   Potential  common  stock,  which  includes  options,
               warrants  and  convertible   subordinated   notes  and  preferred
               securities,   are  not   included  in  the  net  loss  per  share
               calculation  as their  effect is  anti-dilutive.  The Company has
               presented  net loss per share from  discontinued  operations  and
               extraordinary  gain on  sales  of  operations  of  NETCOM  in the
               consolidated statement of operations for all periods presented.

         (c)   Reclassifications

               Certain 1998 amounts have been  reclassified  to conform with the
               1999 presentation.

         (a)   Network Services

               On July 15, 1999,  the  Company's  board of  directors  adopted a
               formal  plan  to  dispose  of the  Company's  investments  in its
               wholly-owned subsidiaries, ICG Fiber Optic Technologies, Inc. and
               Fiber Optic  Technologies of the Northwest,  Inc.  (collectively,
               "Network Services"). The Company's plan of disposal consists of a
               sale for cash  proceeds of the business of Network  Services.  On
               July 19, 1999,  the Company signed a letter of intent to sell all
               of the  capital  stock of Network  Services  to a third party for
               cash  proceeds  of  approximately  $24.0  million.   The  Company
               anticipates the sale of Network Services will be completed within
               the next 12 months.

               The  Company's  consolidated  financial  statements  reflect  the
               operations of Network  Services as  discontinued  for all periods
               presented.  Additionally,  during the three months ended June 30,

               estimated  losses on  disposal  of  Network  Services,  including
               approximately  $0.3  million for  estimated  operating  losses of
               Network  Services  during the phase out  period.  Included in net

               disposal  consists of a sale for cash proceeds of the business of
               Satellite Services.  On August 11, 1999, the Company entered into
               a  definitive  agreement  to sell  all of the  capital  stock  of
               Satellite  Services  to  a  third  party  for  cash  proceeds  of
               approximately  $100.0  million.  The company  expects to record a

               included in the Company's  consolidated  financial  statements in

            (c)    Zycom

               The Company  owns a 70% interest in Zycom  Corporation  ("Zycom")
               which,  through  its  wholly  owned  subsidiary,   Zycom  Network
               Services, Inc. ("ZNSI"),  operated an 800/888/900 number services
               bureau and a switch  platform in the United  States and  supplied
               information  providers and commercial accounts with audiotext and
               customer  support  services.  In June 1998, Zycom was notified by
               its largest  customer of the  customer's  intent to transfer  its
               call traffic to another service bureau.  In order to minimize the
               obligation  that this loss in call traffic would  generate  under
               Zycom's volume discount agreements with AT&T Corp. ("AT&T"),  its
               call transport  provider,  ZNSI entered into an agreement on July
               1, 1998 with an unaffiliated entity, ICN Limited ("ICN"), whereby
               ZNSI assigned the traffic of its largest  audiotext  customer and
               its other 900-number customers to ICN, effective October 1, 1998.
               As part of this  agreement,  ICN assumed all minimum call traffic
               volume obligations to AT&T.

               The call traffic assigned to ICN represented approximately 86% of
               Zycom's revenue for the year ended December 31, 1998. The loss of
               this   significant   portion   of   Zycom's   business,   despite
               management's  best  efforts to secure  other  sources of revenue,
               raised  substantial  doubt as to Zycom's  ability to operate in a
               manner which would benefit Zycom's or the Company's shareholders.
               Accordingly,  on August  25,  1998,  Zycom's  board of  directors
               approved a plan to wind down and ultimately  discontinue  Zycom's
               operations.  On October 22, 1998, Zycom completed the transfer of
               all customer traffic to other providers.  On January 4, 1999, the
               Company completed the sale of the remainder of Zycom's long-lived
               operating  assets to an unrelated  third party for total proceeds
               of $0.2  million.  As Zycom's  assets were  recorded at estimated
               fair  market  value at  December  31,  1998,  no gain or loss was
               recorded on the sale during the six months  ended June 30,  1999.
               Zycom anticipates the disposition of its remaining assets and the
               discharge  of  its  remaining   operating   liabilities  will  be
               completed in 1999.

               The  Company's  consolidated  financial  statements  reflect  the
               operations of Zycom as  discontinued  for all periods  presented.
               Zycom reported net losses from operations of  approximately  $1.2
               million for the period from August 25, 1998 to December  31, 1998
               and  reported  no income or losses  from  operations  for the six
               months  ended June 30,  1999.  The  Company  has  accrued for all
               expected  future net  losses of Zycom.  Included  in net  current

          (d)    NETCOM

               On February 17, 1999,  the Company sold certain of the  operating
               assets and liabilities of NETCOM to MindSpring Enterprises, Inc.,
               an ISP located in Atlanta, Georgia ("MindSpring"). Total proceeds
               from the sale were $245.0  million,  consisting of $215.0 million
               in cash and 376,116 shares of common stock of MindSpring,  valued
               at approximately $79.76 per share at the time of the transaction.
               Assets and liabilities sold to MindSpring  include those directly
               related to the domestic  operations of NETCOM's Internet dial-up,
               dedicated  access and Web site hosting  services.  In conjunction
               with  the  sale  to  MindSpring,  the  Company  entered  into  an
               agreement  to lease  to  MindSpring  for a  one-year  period  the
               capacity of certain  network  operating  assets formerly owned by
               NETCOM and retained by the Company.  MindSpring  is utilizing the
               Company's  network  capacity  to provide  Internet  access to the
               dial-up  services  customers  formerly owned by NETCOM.  Over the
               term of the one-year agreement, MindSpring is required to pay the
               Company a minimum  of $27.0  million  for the  Company's  network
               capacity,  although such minimum is subject to increase dependent
               upon network usage.  In addition,  the Company is receiving for a
               one-year  period 50% of the gross  revenue  earned by  MindSpring
               from the dedicated  access  customers  formerly  owned by NETCOM,
               estimated to be  approximately  $10.0 million for the term of the
               agreement.  The Company, through NetAhead, is currently utilizing
               the  retained  network  operating  assets  to  provide  wholesale
               capacity and other  enhanced  network  services to MindSpring and
               intends  to   provide   similar   services   to  other  ISPs  and
               telecommunications providers in the future. The carrying value of
               the  assets  retained  by the  Company  was  approximately  $21.7
               million,   including   approximately  $17.5  million  of  network
               equipment,  on  February  17,  1999.  The Company  also  retained
               approximately  $11.3 million of accrued  liabilities  and capital
               lease obligations.

               On March 16, 1999,  the Company sold all of the capital  stock of
               NETCOM's   international   operations   for  total   proceeds  of
               approximately  $41.1 million.  MetroNET  Communications  Corp., a
               Canadian  entity,  and  Providence  Equity  Partners,  located in
               Providence,  Rhode Island ("Providence"),  together purchased the
               80%  interest  in  NETCOM   Canada  Inc.   owned  by  NETCOM  for
               approximately  $28.9  million in cash.  Additionally,  Providence
               purchased  all of the  capital  stock of NETCOM  Internet  Access
               Services Limited,  NETCOM's operations in the United Kingdom, for
               approximately $12.2 million in cash.

(3)      Discontinued Operations (continued)

               During the six months ended June 30, 1999, the Company recorded a
               combined  gain  on the  sales  of the  operations  of  NETCOM  of
               approximately   $193.0   million,   net  of   income   taxes   of
               approximately  $6.4 million.  Offsetting the gain on the sales is
               approximately  $16.6  million of net losses  from  operations  of
               NETCOM  from  November  3, 1998 (the date on which the  Company's
               board of  directors  adopted  the  formal  plan to dispose of the
               operations   of   NETCOM)   through   the  dates  of  the  sales.
               Additionally,  since the Company  expects to  generate  operating
               costs in excess of revenue under its network  capacity  agreement
               with  MindSpring  and  the  terms  of  the  sale  agreement  were
               dependent upon and  negotiated in  conjunction  with the terms of
               the   network   capacity   agreement,    the   Company   deferred
               approximately  $26.0  million  of  the  proceeds  from  the  sale
               agreement  to be  applied  on a  periodic  basis  to the  network
               capacity  agreement.  The deferred proceeds are recognized in the
               Company's  statement  of  operations  as the Company  incurs cash
               operating   losses   under  the   network   capacity   agreement.
               Accordingly,  the  Company  does  not  expect  to  recognize  any
               revenue,  operating costs or selling,  general and administrative
               expenses from services provided to MindSpring for the term of the
               agreement.  Any  incremental  revenue or costs generated by other
               customers,  or by other  services  provided  to  MindSpring,  are
               recognized in the Company's  consolidated statement of operations
               as  incurred.  During the three  months and six months ended June
               30, 1999,  the Company  applied  $3.8 million and $10.5  million,
               respectively, of deferred proceeds from the sale of the operating
               assets  and  liabilities  of  NETCOM  to  the  network   capacity
               agreement with MindSpring, which entirely offset the costs of the
               Company's  operations  under the agreement.  Since the operations
               sold were  acquired by ICG in a  transaction  accounted  for as a
               pooling of interests,  the gain on the sales of the operations of
               NETCOM is  classified as an  extraordinary  item in the Company's
               consolidated statement of operations.

(4)      Investments

          As discussed in note 3, the Company  received 376,116 shares of common
          stock of MindSpring,  valued at $79.76 per share, or $30.0 million, at
          the time of the transaction,  as partial consideration for the sale of
          the domestic operations of NETCOM. In April 1999, the Company sold its
          investment  in  MindSpring  for net  proceeds of  approximately  $30.4
          million. The Company has recorded a gain of approximately $0.4 million
          in its statement of operations for the six months ended June 30, 1999.

          On March 30, 1999,  the Company  purchased,  for  approximately  $10.0
          million in cash,  454,545  shares of  restricted  Series D-1 Preferred
          Stock (the "NorthPoint Preferred Stock") of NorthPoint  Communications
          Holdings,  Inc., a Delaware corporation and competitive local exchange
          carrier  ("CLEC") based in San Francisco,  California  ("NorthPoint").
          The NorthPoint  Preferred Stock has no voting rights and is ultimately
          convertible  into a voting class of common stock of NorthPoint,  at an
          exchange  price  which  represents  a  discount,  as  provided  in the
          relevant  documentation,  to the  initial  public  offering  price  of
          NorthPoint's  common stock. The Company is restricted from selling the
          NorthPoint  Preferred Stock or securities  obtained upon conversion of
          the NorthPoint  Preferred  Stock until March 23, 2000. On May 5, 1999,
          NorthPoint  completed the initial public offering of its common stock,
          at which time the NorthPoint Preferred Stock, and additional shares of
          NorthPoint  Preferred Stock obtained as a result of stock splits, were
          automatically  converted  into  shares  of  Class B  common  stock,  a
          nonvoting class of common stock of NorthPoint (the "NorthPoint Class B
          Shares"),  which  are  convertible  on or after  March  23,  2000 on a
          one-for-one  basis into a voting class of common stock of  NorthPoint.
          The Company will account for its  investment in  NorthPoint  under the
          cost  method of  accounting  until the  NorthPoint  Class B Shares are
          converted into voting and tradable  common stock of NorthPoint,  after
          which the investment will be classified as a trading security.

              (a) Mortgage Loan Payable

                  Effective January 1, 1999, the Company purchased its corporate
                  headquarters  building,  land and improvements  (collectively,
                  the "Corporate Headquarters") for approximately $43.4 million,
                  which amount represents  historical cost and approximates fair
                  value.  The  Company,   through  a  newly  formed  subsidiary,
                  financed  the purchase  primarily  through a loan secured by a
                  mortgage  on the  Corporate  Headquarters,  guaranteed  by ICG
                  Services, Inc. The amended loan agreement,  dated May 1, 1999,
                  requires monthly interest payments at an initial interest rate
                  of 14.77% per annum which rate  increases  annually by 0.003%,
                  with the mortgage  balance due January 31, 2013. The seller of
                  the   Corporate   Headquarters   has  retained  an  option  to
                  repurchase  the Corporate  Headquarters  at the original sales
                  price,  which  option  is  exercisable  from  January  1, 2004
                  through January 31, 2012.

                  On August 12, 1999, ICG Equipment and NetAhead  entered into a
                  $200.0 million senior secured financing  facility (the "Senior
                  Facility")  consisting  of a $75.0 million term loan, a $100.0
                  million  term  loan  and a  $25.0  million  revolving  line of
                  credit.  The Senior Facility is guaranteed by ICG Services and
                  is secured by the assets of ICG Equipment and NetAhead.

                  As required under the terms of the loan, the Company  borrowed
                  on August 12, 1999 the  available  $75.0  million on the $75.0
                  million  term  loan.  The loan  bears  interest  at an  annual
                  interest  rate of LIBOR plus 3.5% or the base rate, as defined
                  in the credit  agreement,  plus 2.5%, at the Company's  option
                  (10.5% on August  12,  1999).  Quarterly  repayments  commence
                  September  30,  1999  and  require   quarterly   loan  balance
                  reductions  of 0.25%  through June 30, 2005 with the remaining
                  outstanding  balance  to be  repaid  during  the  final  three
                  quarters of the loan term. The $75.0 million term loan matures
                  on March 31, 2006.

(5)      Long-term Debt and Redeemable Preferred Stock of Subsidiary (continued)

                  On August 12, 1999,  the Company  borrowed $5.0 million on the
                  $100.0  million term loan,  which is available  through August
                  10, 2000 at an initial annual interest rate of LIBOR plus 3.5%
                  or the base rate,  as defined  in the credit  agreement,  plus
                  2.125%,  at the Company's option (10.125% on August 12, 1999).
                  Quarterly  repayments  commence September 30, 2002 and require
                  aggregate  loan  balance  reductions  of 25% through  June 30,
                  2003, 35% through June 30, 2004 and 40% through June 30, 2005.
                  The $100.0 million term loan matures on June 30, 2005.

                  The  $25.0  million  revolving  line of  credit  is  available
                  through  the  maturity  date of June  30,  2005 at an  initial
                  annual  interest  rate of LIBOR plus 3.5% or the base rate, as
                  defined in the credit agreement, plus 2.125%, at the Company's
                  option.

                  The terms of the Senior Facility  provide certain  limitations
                  on the use of proceeds,  additional  indebtedness,  dividends,
                  prepayment of the Senior Facility and other  indebtedness  and
                  certain  other  transactions.  Additionally,  the  Company  is
                  subject to certain  financial  covenants  based on its results
                  and the  results of ICG  Services.  The Company is required to
                  pay  commitment  fees  ranging  from  0.625% to 1.375% for the
                  unused  portion  of  available  borrowings  under  the  Senior
                  Facility.

 (6)      Commitments and Contingencies

          (a)  Network Construction

               In March 1996, the Company and Southern California Edison Company
               ("SCE") 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 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 $126.9 million at June 30, 1999.
               The  agreement  has been  accounted for as a capital lease in the
               accompanying consolidated balance sheets.

               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 in 1999. The Company is responsible  for
               payment  on the  construction  as  segments  of the  network  are
               completed and has incurred approximately $24.9 million as of June

(6)      Commitments and Contingencies (continued)

               30, 1999,  with remaining costs  anticipated to be  approximately
               $10.1  million.  As part  of this  agreement,  the  Company  also
               committed to purchase $6.0 million in network capacity from Qwest
               prior  to the  end  of  1999.  The  Company's  capacity  purchase
               commitment was cancelled by Qwest,  without further obligation by
               the Company,  in  conjunction  with the Company's  additional IRU
               agreement with Qwest, signed on June 25, 1999.

               On June 25, 1999,  the Company signed an agreement to lease fiber
               optic  capacity to Qwest for a minimum  10-year term. The Company
               will  account for the capacity  agreement as a sales-type  lease.
               Revenue will be recognized on a  percentage-of-completion  basis,
               as the network build-out is completed and is available for use by
               Qwest. The $32.0 million received by the Company on June 29, 1999
               for Qwest's total  payment on the capacity  agreement is included
               in deferred revenue in the Company's  consolidated  balance sheet
               at June 30, 1999.

          (b)  Network Capacity and Line Purchase Commitments

               In November 1998, the Company entered into two service agreements
               with WorldCom Network Services,  Inc.  ("WorldCom").  Both of the
               agreements have three-year  terms and were effective in September
               1998. Under the Telecom Services Agreement, WorldCom provides, at
               designated rates, switched  telecommunications services and other
               related services to the Company,  including termination services,
               toll-free  origination,  switched  access,  dedicated  access and
               travel  card  services.   Under  the  Carrier  Digital   Services
               Agreement,  WorldCom  provides the Company,  at designated rates,
               with  the  installation   and  operation  of  dedicated   digital
               telecommunications interexchange services, local access and other
               related  services,  which the Company believes  expedites service
               availability to its customers.  Both agreements  require that the
               Company provide  WorldCom with certain  minimum monthly  revenue,
               which if not met,  would  require  payment by the Company for the
               difference  between the minimum commitment and the actual monthly
               revenue.  Additionally,   both  agreements  limit  the  Company's
               ability  to  utilize  vendors  other than  WorldCom  for  certain
               telecommunications  services  specified  in the  agreements.  The
               Company's  policy is to accrue and include in operating costs the
               effect of any  shortfall  in minimum  revenue  commitments  under
               these  agreements in the period in which the shortfall  occurred.
               The  Company  has  successfully   achieved  all  minimum  revenue
               commitments to WorldCom under these  agreements  through June 30,
               1999.

               In  March  1999,  the  Company  entered  into an  agreement  with
               NorthPoint,   which   designates   NorthPoint  as  the  Company's
               exclusive  digital  subscriber line ("DSL") provider through June
               1, 2001. Under the agreement, the Company is required to purchase
               49,000 digital subscriber lines before June 1, 2001 at designated
               intervals.  In  return,  the  Company  receives  substantial  DSL
               service  price   discounts   and  enhanced   market  access  from
               NorthPoint.   Price  discounts  are  determined   pursuant  to  a
               graduated  schedule  based on the  number of  digital  subscriber
               lines purchased by the Company,  with maximum discounts  achieved
               by purchasing  75,000 digital  subscriber lines over the two-year
               term. The Company's  policy is to accrue and include in operating
               costs the effect of any shortfall in DSL installations  under its
               agreement  with  NorthPoint  in the period in which the shortfall
               occurred. The 49,000 digital subscriber line purchase requirement
               and the price  discounts  are  adjustable  based on  NorthPoint's
               compliance with a commitment schedule of DSL service availability
               for various U.S. locations.  Additionally,  the Company agreed to
               sell its existing DSL equipment to NorthPoint  for total proceeds
               of approximately $2.7 million.

(6)      Commitments and Contingencies (continued)

         (c)   Other Commitments

               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   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 $117.1 million at June 30, 1999.

         (d)   Transport and Termination Charges

               The Company has recorded revenue of  approximately  $4.9 million,
               $58.3 million and $70.9 million for fiscal 1997,  fiscal 1998 and
               the six months ended June 30, 1999, respectively,  for reciprocal
               compensation  relating to the transport and  termination of local
               traffic  to ISPs  from  customers  of  incumbent  local  exchange
               carriers   ("ILECs")   pursuant   to   various    interconnection
               agreements.  Some of the  ILECs  have not paid  most of the bills
               they  have   received   from  the  Company   and  have   disputed
               substantially  all of these charges based on the belief that such
               calls are not local traffic as defined by the various  agreements
               and not subject to payment of transport and  termination  charges
               under state and federal  laws and public  policies.  As a result,
               the Company  expects  receivables  from transport and termination
               charges will continue to increase  until these disputes have been
               resolved.

               The  resolution  of these  disputes  will be based on  rulings by
               state   public   utility   commissions   and/or  by  the  Federal
               Communications  Commission  ("FCC").  To date,  there  have  been
               favorable final rulings from 31 state public utility  commissions
               that  ISP  traffic  is  subject  to  the  payment  of  reciprocal
               compensation under current  interconnection  agreements.  Many of
               these state commission decisions have been appealed by the ILECs.
               To date,  four  federal  district  court  decisions,  one federal
               circuit  court of appeals  decision and one state court  decision
               have been issued  upholding state commission  decisions  ordering
               the  payment  of  reciprocal  compensation  for ISP  traffic.  On
               February  25,  1999,  the FCC  issued a decision  that  ISP-bound
               traffic  is  largely  jurisdictionally  interstate  traffic.  The
               decision  relies on the  long-standing  federal  policy  that ISP
               traffic,  although  jurisdictionally  interstate,  is  treated as
               though it is local  traffic for pricing  purposes.  The  decision
               also emphasizes that because there are currently no federal rules
               governing   intercarrier   compensation  for  ISP  traffic,   the
               determination as to whether such traffic is subject to reciprocal
               compensation  under the terms of  interconnection  agreements  is
               properly  made by the state  commissions  and that  carriers  are
               bound by their  interconnection  agreements and state  commission
               decisions  regarding the payment of reciprocal  compensation  for
               ISP  traffic.  The  FCC has  initiated  a  rulemaking  proceeding
               regarding   the  adoption  of   prospective   federal  rules  for
               intercarrier  compensation  for ISP  traffic.  In its  notice  of
               rulemaking,  the FCC expresses its preference  that  compensation
               rates for this traffic continue to be set by negotiations between
               carriers,  with disputes  resolved by  arbitrations  conducted by
               state commissions, pursuant to the Telecommunications Act of 1996
               (the  "Telecommunications  Act"). Since the issuance of the FCC's
               decision on February  25,  1999,  15 state  utility  commissions,
               including  four  states  in  which  the  Company   provides  CLEC
               services,  have either  ruled or  reaffirmed  that ISP traffic is
               subject to reciprocal  compensation under current interconnection
               agreements,  and two state  commissions  have  declined  to apply
               reciprocal compensation for ISP traffic.

(6)      Commitments and Contingencies (continued)

               On May 5, 1999, the Public Utilities  Commission of Ohio ("PUCO")
               issued a decision  affirming  its August 1998  decision  that ISP
               traffic is subject to reciprocal compensation under the Company's
               current  interconnection  agreement  with  Ameritech  Corporation
               ("Ameritech").  The PUCO also  denied  Ameritech's  request for a
               stay of its obligation to remit payment to the Company. After the
               PUCO issued the May 5, 1999 ruling,  the Company  received  $43.1
               million  during the three  months ended June 30, 1999 for amounts
               owed by Ameritech  for  reciprocal  compensation.  Ameritech  has
               filed for  judicial  review  of the PUCO  decision.  The  Company
               cannot  predict  the  final  outcome  on the  merits of the court
               appeal.   Additionally,   on  June  4,  1999,  Southwestern  Bell
               Telephone  Company  ("SWBT")  remitted  payment to the Company of
               $1.8 million for reciprocal  compensation owed to the Company for
               traffic  from  SWBT  customers  in  Texas to ISPs  served  by the
               Company.  On June 21, 1999, the Alabama Public Service Commission
               ("PSC")   issued   a   decision   that   BellSouth    Corporation
               ("BellSouth")   is  required   to  pay  the  Company   reciprocal
               compensation  for ISP traffic.  The PSC's June 21, 1999  decision
               modified its March 1999 decision  that had found that  reciprocal
               compensation  is owed for  Internet  traffic  under  certain CLEC
               interconnection  agreements at issue in the proceeding.  The June
               21, 1999 PSC decision held that the Company should be treated the
               same as the other CLECs that  participated  in the proceeding and
               for which the  Alabama  PSC  previously  ordered  the  payment of
               reciprocal compensation.  BellSouth has filed for judicial review
               of both the March 4,  1999 and June 21,  1999 PSC  decisions.  On
               July 26, 1999 the California Public Utilities Commission issued a
               decision affirming a previous decision, issued October 1998, that
               held that  reciprocal  compensation  must be paid by Pacific Bell
               and GTE  California  for the  termination of ISP traffic by CLECs
               under existing interconnection  agreements. On July 28, 1999, the
               Colorado  Public  Utilities  Commission  approved a decision that
               orders  US  WEST  Communications,  Inc.  ("US  WEST")  to pay the
               Company reciprocal  compensation for calls from US WEST customers
               to ISPs  served by the  Company.  The  decision  resolves  in the
               Company's favor a complaint that was filed by the Company in June
               1998.

               The  Company has also  recorded  revenue of  approximately  $19.1
               million and $7.6 million for fiscal 1998 and the six months ended
               June 30,  1999,  respectively,  related  to other  transport  and
               termination  charges  to the  ILECs,  pursuant  to the  Company's
               interconnection  agreements  with these  ILECs.  Included  in the
               Company's  trade  receivables  at December  31, 1998 and June 30,
               1999 are $72.8 million and $100.7 million,  respectively, for all
               receivables   related  to  reciprocal   compensation   and  other
               transport and termination  charges.  The  receivables  balance at
               June 30, 1999 is net of an allowance of $9.6 million for disputed
               amounts.

               As  the  Company's  interconnection   agreements  expire  or  are
               extended,  rates for transport and termination  charges are being
               and  will  continue  to be  renegotiated.  Some of the  Company's
               agreements  are already  being  affected.  Although the Company's
               interconnection agreement with BellSouth has expired, the Company
               has received written notification from BellSouth that the Company
               may  continue   operating   under  the  expired   interconnection
               agreement,  until such agreement is renegotiated or arbitrated by
               the relevant  state  commissions.  On May 27,  1999,  the Company
               filed petitions with the state  commissions of Alabama,  Georgia,
               North Carolina,  Kentucky,  Tennessee and Florida for arbitration
               with BellSouth.  The arbitration  proceedings are ongoing in each
               of these  states.  Additionally,  the  Company's  interconnection
               agreement with Ameritech recently was extended from June 15, 1999
               to  February   15,   2000.   The   Company's   extension  of  its
               interconnection  agreement with Ameritech  includes reduced rates
               for transport and  termination  charges,  and the Company expects
               that its negotiations  and arbitrations  with BellSouth will also
               affect the rates for transport and termination  charges  included

(6)      Commitments and Contingencies (continued)

               in its existing  interconnection  agreement with  BellSouth.  The
               Company's remaining interconnection agreements expire in 1999 and
               2000,  and the  Company  has  commenced  renegotiations  with the
               ILECs.  While the  Company  believes  that all  revenue  recorded
               through June 30, 1999 is collectible and that future revenue from
               transport  and  termination  charges  billed under the  Company's
               current interconnection agreements will be realized, there can be
               no assurance that future  regulatory and judicial rulings will be
               favorable to the Company,  or that  different  pricing  plans for
               transport and termination  charges  between  carriers will not be
               adopted  when  the  Company's   interconnection   agreements  are
               renegotiated  or  arbitrated,   or  as  a  result  of  the  FCC's
               rulemaking  proceeding on future  compensation  methods. In fact,
               the  Company  believes  that  different  pricing  plans  will  be
               considered  and adopted,  and  although the Company  expects that
               revenue  from  transport  and  termination  charges  likely  will
               decrease as a percentage of total revenue from local  services in
               periods   after  the   expiration   of  current   interconnection
               agreements,  the Company's local termination  services still will
               be  required  by  the  ILECs  and  must  be  provided  under  the
               Telecommunications  Act,  and likely  will  result in  increasing
               volume in minutes due to the growth of the  Internet  and related
               services  markets.  The Company  expects to negotiate  reasonable
               compensation and collection terms for local termination services,
               although there is no assurance that such compensation will remain
               consistent with current levels.

          (e)  Litigation

               On  April  4,  1997,  certain   shareholders  of  Zycom  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 plaintiffs were denied class certification by
               the  trial  court  and the Court of  Appeals  affirmed  the trial
               court's  decision.  Trial has been  tentatively  set for  October
               1999. 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  material  adverse  effect  on  the  Company's  financial
               condition, results of operations or cash flows.

(7)      Business Segments

         The Company conducts  transactions with external  customers through the
         operations of its Telecom Services business unit. Shared administrative
         services  are  provided  to Telecom  Services  by  Corporate  Services.
         Corporate  Services  consists  of  the  operating   activities  of  ICG
         Communications, Inc., ICG Funding, LLC, ICG Canadian Acquisition, Inc.,
         ICG Holdings (Canada) Co., ICG Holdings,  Inc., ICG Services, Inc., ICG
         Corporate Headquarters,  L.L.C. and ICG 161, L.P., which primarily hold
         securities  and other  nonoperating  assets and provide  certain legal,
         accounting  and finance,  personnel  and other  administrative  support
         services to the business units.

         Direct and certain  indirect  costs  incurred by Corporate  Services on
         behalf of Telecom  Services are allocated to Telecom  Services based on
         the  nature  of the  underlying  costs.  Transactions  between  Telecom
         Services and  Corporate  Services for services  performed in the normal
         course of  business  are  recorded  at amounts  which are  intended  to
         approximate fair value.

</TABLE>
          (a)  EBITDA (before nonrecurring and noncash charges) consists of loss
               from  continuing   operations  before  interest,   income  taxes,
               depreciation  and  amortization,   provision  for  impairment  of
               long-lived  assets and other,  net operating  costs and expenses,
               including  deferred  compensation and net loss (gain) on disposal
               of  long-lived  assets,  other  expense,  net and  accretion  and
               preferred dividends on preferred  securities of subsidiaries,  or
               simply,  revenue less  operating  costs and selling,  general and
               administrative expenses.  EBITDA (before nonrecurring and noncash
               charges)  is  presented  as the  Company's  measure of  operating
               performance  because  it  is  a  measure  commonly  used  in  the
               telecommunications  industry.  EBITDA  (before  nonrecurring  and
               noncash  charges) 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 for the periods indicated.  EBITDA
               (before  nonrecurring  and noncash  charges) is not a measurement
               under  generally  accepted  accounting   principles  and  is  not
               necessarily  comparable  with similarly  titled measures of other
               companies.

          (b)  Although not included in EBITDA (before  nonrecurring and noncash
               charges),  which represents the measure of operating  performance
               used by management to evaluate operating results, the Company has
               supplementally   provided   depreciation   and  amortization  and
               interest  expense for Telecom  Services and  Corporate  Services.
               Interest   expense  excludes  amounts  charged  for  interest  on
               outstanding cash advances and expense allocations between Telecom
               Services and Corporate Services.

          (c)  Capital expenditures include assets acquired under capital leases
               and excludes payments for construction of the Company's corporate
               headquarters and corporate  headquarters  assets acquired through
               the issuance of long-term debt.

          (d)  Total assets of Telecom Services and Corporate  Services excludes
               investments  in  consolidated  subsidiaries  which  eliminate  in
               consolidation.

(8)      Provision for Impairment of Long-Lived Assets

         During the three  months ended June 30,  1999,  the Company  recorded a
         provision for impairment of long-lived  assets of $29.3 million,  which
         relates to the  impairment  of  software  and other  capitalized  costs
         associated with Telecom Services'  in-process  billing and provisioning
         system development projects. The provision for impairment of long-lived
         assets was based on  management's  decision  to select new  vendors for
         each of these  systems,  which  vendors  are  expected  to provide  the
         Company  with  billing  and   provisioning   solutions   with  improved
         functionality and earlier delivery dates at significantly  lower costs.
         The Company's  in-process billing and provisioning  systems were either
         not  operational  or  were  serving  minimal   customers  at  the  time
         management  determined the carrying value of the underlying  assets was
         not recoverable.

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  enhanced  telephony  and  network  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 of operations for
the three  months and six  months  ended June 30,  1998 and 1999  represent  the
consolidated  operating  results of the  Company.  See the  unaudited  condensed
consolidated  financial  statements of the Company for the six months ended June
30,  1999  included  elsewhere  herein.  The  Company's  consolidated  financial
statements reflect the operations of Network Services, Satellite Services, Zycom
and NETCOM as discontinued  for all periods  presented.  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

     ICG  Communications  Inc.  ("ICG" or the  "Company") is one of the nation's
leading competitive  integrated  communications  providers ("ICPs") based on the
industry's  1998 revenue.  ICPs seek to provide an  alternative to the incumbent
local   exchange   carriers   ("ILECs"),   long  distance   carriers  and  other
communications service providers for a full range of communications  services in
the increasingly deregulated  telecommunications industry. The Company's Telecom
Services  primarily  include its  competitive  local exchange  carrier  ("CLEC")
operations,  in which the Company  operates fiber networks in regional  clusters
covering major  metropolitan  statistical areas in California,  Colorado,  Ohio,
Texas and the  Southeast,  offering  local,  long  distance,  data and  enhanced
telephony  services to business  end users and ISPs.  Additionally,  in February
1999, the Company began providing wholesale network services over its nationwide
data network. Until the completion of the sales of such operations,  the Company
also provides a wide range of network systems integration  services and maritime
and international satellite transmission services.  Network Services consists of
information  technology services and selected networking  products,  focusing on
network  design,  installation,  maintenance  and  support.  Satellite  Services
consists of satellite  voice,  data and video services  provided to major cruise
lines,  the U.S.  Navy, the offshore oil and gas industry and ICPs. As a leading
participant  in  the  rapidly  growing   competitive  local   telecommunications
industry,  the Company has experienced  significant  growth,  with total revenue
increasing  from  approximately  $72.7 million for fiscal 1996 to  approximately
$402.6 million for the 12-month  period ended June 30, 1999. 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  communications
service offerings.

     The Federal  Telecommunications Act of 1996 (the "Telecommunications  Act")
and pro-competitive state regulatory  initiatives have substantially changed the
telecommunications  regulatory  environment  in the  United  States.  Under  the
Telecommunications  Act, the Company is permitted  to offer all  interstate  and
intrastate telephone services,  including  competitive local dial tone. In early
1997, the Company began  marketing and selling local dial tone services in major
metropolitan  areas in  California,  Colorado,  Ohio and the  Southeast  and, in
December 1998,  began offering  services in Texas through an acquired  business.
During  fiscal 1997,  fiscal 1998 and the six months  ended June 30,  1999,  the
Company sold 178,470, 206,458 and 132,122 local access lines, respectively,  net
of cancellations of which 494,405 were in service at June 30, 1999. In addition,
the Company's regional fiber networks have grown from 2,143 fiber route miles at
the end of fiscal 1996 to 4,406 fiber route miles at June 30, 1999.  The Company
had 29 operating high capacity  digital circuit switches and 16 operational data
communications  switches  at June 30,  1999,  and  plans to  install  additional
switches as demand  warrants.  As a complement  to its local  exchange  services
offered to business end users,  the Company markets  bundled  service  offerings
provided over its regional fiber network which include long  distance,  enhanced
telecommunications  services and data services.  Additionally,  the Company owns
and operates a nationwide data network with 236 points of presence ("POPs") over
which the  Company  recently  began  providing  wholesale  Internet  access  and
enhanced network services to MindSpring  Enterprises,  Inc., an Internet service
provider ("ISP") located in Atlanta,  Georgia  ("MindSpring")  and certain other
ISPs, and intends to offer similar services to more ISPs and  telecommunications
providers in the future.

     To better focus its efforts on its core Telecom  Services  operations,  the
Company  made  further  progress  toward the  disposal of certain  assets  which
management believes do not complement its overall business strategy. On July 15,
1999, the Company's  board of directors  adopted a formal plan to dispose of the
operations  of  the  Company's  wholly-owned   subsidiaries,   ICG  Fiber  Optic
Technologies,   Inc.  and  Fiber  Optic  Technologies  of  the  Northwest,  Inc.
(collectively, "Network Services") and ICG Satellite Services, Inc. and Maritime
Telecommunications Network, Inc. (collectively,  "Satellite Services"),  through
the sales of such businesses for cash proceeds.  The Company has signed a letter
of intent to a third party to sell all of the capital stock of Network Services.
On August 11, 1999, the Company entered into a definitive  agreement to sell all
of the capital stock of Satellite Services to a third party for cash proceeds of
approximately  $100.0  million.  The  Company  anticipates  the sales of Network
Services and Satellite Services will be completed during the next 12 months. Due
primarily  to the  loss of a  major  customer,  which  generated  a  significant
obligation under a volume discount  agreement with its call transport  provider,
the board of directors of Zycom Corporation  ("Zycom") approved a plan on August
25, 1998 to wind down and ultimately discontinue Zycom's operations.  On October
22,  1998,  Zycom  completed  the  transfer  of all  customer  traffic  to other
providers  and on  January  4,  1999,  the  Company  completed  the  sale of the
remainder of Zycom's long-lived operating assets to an unrelated third party. On
February  17,  1999,  the  Company  sold  certain  of the  operating  assets and
liabilities  of  NETCOM  On-Line  Communication  Services,  Inc.  ("NETCOM")  to
MindSpring  for total  proceeds of $245.0  million,  and on March 16, 1999,  the
Company sold all of the capital  stock of NETCOM's  international  operations in
Canada  and the  United  Kingdom  to other  unrelated  third  parties  for total
proceeds of  approximately  $41.1 million.  During the six months ended June 30,
1999,  the Company  recorded a combined  gain on the sales of the  operations of
NETCOM of  approximately  $193.0 million,  net of income taxes of  approximately
$6.4 million. Offsetting the gain on the sales is approximately $16.6 million of
net losses from  operations  of NETCOM from  November 3, 1998 (the date on which
the  Company's  board of  directors  adopted  the formal  plan to dispose of the
operations of NETCOM) through the dates of the sales.  Since the operations sold
were  acquired by the  Company in a  transaction  accounted  for as a pooling of
interests, the gain on the sales of the operations of NETCOM is classified as an
extraordinary item in the Company's  consolidated  statement of operations.  For
fiscal 1996, 1997 and 1998,  Network  Services,  Satellite  Services,  Zycom and
NETCOM combined  reported  revenue of $216.8 million,  $284.7 million and $275.9
million,  respectively,  and EBITDA  losses  (before  nonrecurring  and  noncash
charges) of $(36.0) million, $(13.4) million and $(16.7) million,  respectively.
The  Company's  consolidated  financial  statements  reflect the  operations  of
Network Services,  Satellite Services,  Zycom and NETCOM as discontinued for all
periods presented. The Company will from time to time evaluate all of its assets
as to their core need and, based on such analysis, may sell or otherwise dispose
of assets which do not complement its overall business strategy.

     In conjunction  with the sale to  MindSpring,  the legal name of the NETCOM
subsidiary was changed to ICG NetAhead, Inc. ("NetAhead"). NetAhead has retained
the domestic Internet backbone assets formerly owned by NETCOM which include 236
POPs serving  approximately  700 cities  nationwide.  NetAhead is utilizing  the
retained  network  operating  assets to provide  wholesale  Internet  access and
enhanced  network  services to MindSpring and other ISPs and  telecommunications
providers.  On February 17, 1999, the Company entered into an agreement to lease
to MindSpring for a one-year  period the capacity of certain  network  operating
assets  formerly  owned by NETCOM and  retained by the  Company.  MindSpring  is
utilizing  the  Company's  network  capacity to provide  Internet  access to the
dial-up  services  customers  formerly  owned  by  NETCOM.  Over the term of the
one-year agreement, MindSpring is required to pay the Company a minimum of $27.0
million,  although  such minimum is subject to increase  dependent  upon network
usage.  In addition,  the Company is receiving for a one-year  period 50% of the
gross revenue earned by MindSpring from the dedicated access customers  formerly
owned by NETCOM, estimated to be approximately $10.0 million for the term of the
agreement.  Although the Company expects to generate cash operating losses under
this  agreement,  any such losses will be offset by the periodic  recognition of
approximately $26.0 million of the proceeds from the sale of certain of NETCOM's
domestic  operating  assets and  liabilities  to  MindSpring,  which the Company
deferred on  February  17,  1999.  Accordingly,  the Company  does not expect to
recognize any revenue,  operating costs or selling,  general and  administrative
expenses from services provided to MindSpring for the term of the agreement. Any
incremental revenue or costs generated by other customers,  or by other services
provided to MindSpring,  are recognized in the Company's  consolidated statement
of operations as incurred.

     Additionally,  the Company intends to provide network capacity and enhanced
data services to ISPs and other  telecommunications  providers,  as required. In
December 1998, the Company announced plans to offer several new network services
to its business and ISP customers by utilizing its  nationwide  data network and

                                       27
<PAGE>

service  capabilities to carry  out-of-region  traffic and enhance data services
provided. One of the services currently being offered is modemless remote access
service ("RAS"). RAS, also known as managed modem service, allows the Company to
provide modem access at its own switch  location,  thereby  eliminating the need
for ISPs to deploy  modems  physically  at each of their POPs.  The  benefits to
ISPs, including reduced capital expenditures and the shift of network management
responsibility from the ISPs to the Company, will allow the Company to act as an
aggregator of ISP traffic.  In offering RAS, the Company provides radius routing
and proxy  services at the modem bank  connected to the Company's  local switch,
which  services  are the  authentication  services  necessary  to  validate  and
accurately  route  incoming  call traffic to the ISP. The Company also  provides
transport  services to deliver all Internet  protocol ("IP") data packets either
directly to the ISP, if the ISP is not collocated at the Company's local switch,
or  directly  to the  Internet,  bypassing  the ISP.  Additionally,  through its
network  operations  center,  the Company monitors the usage of each port and is
responsible for the  administration  of all network repair and maintenance.  The
Company is currently  offering  Internet RAS services,  or expanded  originating
services,  to MindSpring and expects to extend such services  offerings to other
ISPs in the  future.  In  August  1998,  the  Company  began  offering  enhanced
telephony services via IP technology.  The Company currently offers this service
in 230 major cities in the United States, which cities account for more than 90%
of the commercial long distance market.  The Company carries the IP traffic over
its  nationwide  data network and  terminates a large portion of the traffic via
its own POPs. The Company also began offering  integrated access service ("IAS")
which allows voice and data traffic to be carried on the same  circuit.  Through
equipment  installed  by the  Company  at  the  customers'  premises  and in the
Company's  central  offices,  IAS  provides  expanded  bandwidth  for  small  to
medium-sized  business  customers as an  alternative  to  purchasing  additional
circuits.  Data traffic,  including Internet traffic, from IAS service offerings
will be carried over the Company's  nationwide network. The Company's nationwide
network will also be utilized in offering peering services to its ISP customers,
in which service offerings the Company will become the general backbone provider
for its customers.  Additionally,  the Company intends to provide other enhanced
network services as demand warrants.

     The Company  will  continue  to expand its  network  and service  offerings
through  construction,  leased facilities,  strategic  alliances and mergers and
acquisitions.  For example,  on December 31, 1998,  the Company  purchased  from
Central and South West Corporation ("CSW") 100% of the partnership  interests in
ICG ChoiceCom, L.P. ("ChoiceCom"),  a strategic alliance with CSW formed for the
purpose of  developing  and  marketing  telecommunications  services  in certain
cities in Texas.  ChoiceCom  is based in Austin,  Texas and  currently  provides
local exchange and long distance  services in Austin,  Corpus  Christi,  Dallas,
Houston and San Antonio,  Texas.  For fiscal 1997 and 1998,  ChoiceCom  reported
revenue of $0.3  million  and $5.8  million,  respectively,  and  EBITDA  losses
(before nonrecurring and noncash charges) of $(5.5) million and $(13.6) million,
respectively.   Additionally,  on  the  acquisition  date,  ChoiceCom  had  five
operating  high  capacity  digital  circuit  switches and two  operational  data
communications switches and had 19,569 access lines in service, including 15,282
access lines  previously sold by ICG on behalf of ChoiceCom.  In March 1999, the
Company entered into an agreement with NorthPoint  Communications,  Inc., a data
CLEC  based  in  San  Francisco,  California  ("NorthPoint"),  which  designates
NorthPoint as the Company's  preferred digital  subscriber line ("DSL") provider
through June 1, 2001. A significant portion of the Company's DSL traffic will be
routed  by  NorthPoint  to the  Company's  asynchronous  transfer  mode  ("ATM")
switches and  transported by the Company either to the ISP, via a point to point
connection or via IP technology,  or directly to the Internet, as required.  The
Company  expects to purchase a minimum of 75,000 digital  subscriber  lines from
NorthPoint during the term of the agreement.  In August 1999, the Company signed
a  nonbinding  letter of intent with a large  national  ISP which is currently a
local  exchange  customer of the Company.  If the  agreement is  finalized,  the
Company  will  provide  Internet  RAS to the ISP for a  five-year  period  for a
minimum  of  $160.0  million  over the term of the  agreement.  The  Company  is
currently  converting the ISP's existing primary rate interface ("PRI") lines to
accommodate  RAS  service and expects to convert a total of 100,000 PRI lines in
conjunction  with the  agreement.  In June  1999,  the  Company  entered  into a
five-year agreement with Qwest  Communications  Corporation  ("Qwest"),  whereby
Qwest has agreed to purchase 100,000 RAS circuits from the Company.  The Company
expects to install a minimum of 80,000 of Qwest's RAS circuits by September  30,
1999,  with the remaining  20,000 RAS circuits to be installed prior to June 29,
2000.  The  Company  also  entered  into  two  long-term  fiber  optic  capacity
agreements with Qwest in June 1999. Under the first agreement,  the Company will
lease more than 7,600  miles of fiber  optic  capacity  from Qwest for a term of
between 8 and 20 years, as determined by the Company.  The Company believes that
the  additional  capacity will  increase the speed and national  presence of the
Company's  fiber optic  network.  Under the second  agreement,  Qwest will lease
certain fiber optic  capacity from the Company,  for a 10-year  minimum term for

                                       28
<PAGE>

total  proceeds of $32.0  million.  In April 1999,  the  Company  announced  its
intention to expand its RAS and other network service  offerings  during 1999 to
the major U.S. markets of Boston, New York,  Washington D.C., Miami, Chicago and
Seattle.

     In conjunction with the increase in its service offerings,  the Company has
and will  continue  to need to spend  significant  amounts on sales,  marketing,
customer  service,  engineering and support personnel prior to the generation of
corresponding revenue. EBITDA, EBITDA (before nonrecurring and noncash charges),
and operating and net losses have generally increased  immediately preceding and
during  periods of relatively  rapid network  expansion and  development  of new
services.  Since  the  quarter  ended  June  30,  1996,  EBITDA  losses  (before
nonrecurring and noncash  charges) have improved for each  consecutive  quarter,
through  and  including  the  quarter  ended June 30, 1999 for which the Company
reported  positive  EBITDA (before  nonrecurring  and noncash  charges) of $15.2
million.  As the Company  provides a greater  volume of higher margin  services,
principally local exchange services,  carries more traffic on its own facilities
rather  than  ILEC  facilities  and  obtains  the  right to use  unbundled  ILEC
facilities,  while  experiencing  decelerating  increases in personnel and other
selling,  general and administrative expenses supporting its operations,  any or
all of which may not occur, the Company anticipates that EBITDA performance will
continue to improve in the near term.

        used  primarily  to obtain  customers.  Although  the  Company  plans to
        migrate lines from resale to higher margin on-switch lines,  there is no
        assurance that it will be successful in executing this strategy.

Three Months Ended June 30, 1999 Compared to Three Months Ended June 30, 1998

     Revenue.  Revenue,  which consists solely of revenue from Telecom Services,
increased  $53.5 million,  or 83%, from $64.2 million for the three months ended
June 30, 1998 to $117.7 million for the three months ended June 30, 1999.  Local
services revenue increased from $29.5 million, or 46% of revenue,  for the three
months ended June 30, 1998 to $76.8  million,  or 65% of revenue,  for the three
months ended June 30, 1999,  primarily  due to an increase in local access lines
from  237,458  lines in service at June 30, 1998 to 494,405  lines in service at
June  30,  1999.  In  addition,   local  access  revenue   includes  revenue  of
approximately $6.6 million and $40.1 million for the three months ended June 30,
1998  and  1999,  respectively,  for  reciprocal  compensation  relating  to the
transport  and  termination  of local  traffic to ISPs from  customers  of ILECs
pursuant to various interconnection agreements.  These agreements are subject to
renegotiation over the next several months. While management believes that these
agreements  will be replaced by  agreements  offering  the Company  some form of
compensation for ISP traffic, the renegotiated  agreements may reflect rates for
reciprocal  compensation  which are  lower  than the  rates  under  the  current
contracts.  See "Liquidity - Transport and Termination  Charges." Special access
revenue  increased from $17.5 million,  or 27% of revenue,  for the three months
ended June 30, 1998 to $23.4  million,  or 20% of revenue,  for the three months
ended  June 30,  1999.  Switched  access  (terminating  long  distance)  revenue
increased to $12.4 million for the three months ended June 30, 1999, compared to
$11.4  million for the three months ended June 30, 1998.  The Company has raised
prices on its wholesale  switched  services product in order to improve margins.
Revenue from long distance  services  decreased  from $5.8 million for the three
months  ended June 30, 1998 to $5.1  million for the three months ended June 30,
1999.  The decrease in long distance  revenue is primarily  attributable  to the
Company's  planned attrition of resale access lines which had high long distance
service  penetration  rates.  Revenue  from data  services  did not  generate  a
material portion of total revenue during either period.

     Operating costs.  Operating costs, which consists solely of operating costs
from Telecom Services,  increased $16.1 million,  or 37%, from $43.3 million for
the three months ended June 30, 1998 to $59.5 million for the three months ended
June 30, 1999.  Additionally,  operating  costs  decreased  as a  percentage  of
revenue  from 67% for the three  months ended June 30, 1998 to 51% for the three
months ended June 30, 1999. 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 volume of
local and special access  services and the increase in network  operating  costs
which include engineering and operations  personnel dedicated to the development
and launch of local  exchange  services.  The decrease in  operating  costs as a
percentage  of revenue is due  primarily  to a greater  volume of higher  margin
services,  principally local exchange services. The Company expects the ratio of
operating  costs to  revenue  will  further  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.

     Selling,  general and administrative  expenses.  Total selling, general and
administrative  ("SG&A")  expenses  increased  $5.1 million,  or 14%, from $37.8

                                       31
<PAGE>

million for the three months ended June 30, 1998 to $43.0  million for the three
months ended June 30, 1999.  Total SG&A  expenses  decreased as a percentage  of
revenue  from 59% for the three  months ended June 30, 1998 to 36% for the three
months ended June 30, 1999.  Telecom Services SG&A expenses increased from $32.0
million,  or 50% of revenue,  for the three  months ended June 30, 1998 to $37.8
million,  or 32% of  revenue,  for the three  months  ended June 30,  1999.  The
increase in absolute dollars is 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. As the Company begins
to benefit from the revenue  generated  by newly  developed  services  requiring
substantial  administrative,  selling  and  marketing  expense  prior to initial
service offerings, Telecom Services has experienced declining SG&A expenses as a
percentage of revenue.  From time to time, the Company will experience increases
in SG&A  expenses as the  Company  prepares  for  offerings  of newly  developed
services.  Corporate  Services SG&A expenses  decreased $0.7 million,  from $5.8
million for the three  months  ended June 30, 1998 to $5.1 million for the three
months  ended June 30,  1999,  primarily  due to the  Company's  purchase of the
corporate  headquarters,  effective  January 1, 1999,  which was leased under an
operating lease during 1998.

     Depreciation and  amortization.  Depreciation  and  amortization  increased
$26.1 million,  or 140%,  for the three months ended June 30, 1999,  compared to
the three months ended June 30, 1998,  primarily due to increased  investment in
depreciable  assets  resulting  from the  continued  expansion of the  Company's
networks  and  services,  in addition to  increased  amortization  arising  from
goodwill  recorded in  conjunction  with three  purchase  business  combinations
completed  during the second  half of fiscal  1998.  The  Company  expects  that
depreciation and amortization will continue to increase as the Company continues
to invest in the expansion and upgrade of its regional fiber and nationwide data
networks.

     Provision for impairment of long-lived  assets.  For the three months ended
June 30, 1999,  provision for  impairment of long-lived  assets of $29.3 million
relates to the  impairment of software and other  capitalized  costs  associated
with Telecom Services'  in-process  billing and provisioning  system development
projects.  The  provision  for  impairment  of  long-lived  assets  was based on
management's decision to select new vendors for these systems, which vendors are
expected to provide the Company with  billing and  provisioning  solutions  with
improved  functionality and earlier delivery dates at significantly lower costs.
The  Company's  in-process  billing  and  provisioning  systems  were either not
operational or were serving minimal customers at the time management  determined
the carrying value of the underlying assets was not recoverable.

     Other, net. Other, net operating costs and expenses  increased $0.4 million
for the three  months  ended June 30,  1999,  compared to the three months ended
June 30, 1998.  For the three months ended June 30, 1999,  other,  net operating
costs and expenses  primarily  includes  deferred  compensation  expense of $0.4
million  related to the Company's  deferred  compensation  arrangement  with its
chief executive  officer.  Other amounts  included in other, net operating costs
and expenses for the three months ended June 30, 1998 and 1999 include net gains
and losses on disposal of miscellaneous long-lived assets.

     Interest  expense.  Interest  expense  increased  $9.8 million,  from $41.5
million for the three months ended June 30, 1998, to $51.3 million for the three
months ended June 30, 1999,  which includes  $47.1 million of noncash  interest.
The Company's interest expense increases, and will continue to increase, because
the principal  amount of its  indebtedness  increases until the Company's senior
indebtedness  begins to pay interest in cash,  beginning in 2001.  Additionally,
interest expense increased due to the increase in long-term debt associated with
the Company's purchase of the corporate headquarters, effective January 1, 1999.

     Interest income.  Interest income decreased $4.7 million, from $8.5 million
for the three  months  ended June 30, 1998 to $3.8  million for the three months
ended June 30, 1999. The decrease is  attributable to the decrease in cash, cash
equivalents and short-term investments as the Company funds operating losses and
continues to invest available cash balances in telecommunications  equipment and
other assets.

     Other expense,  net. Other expense, net increased from $0.3 million for the
three months ended June 30, 1998 to $1.8 million for the three months ended June
30, 1999.  Other expense,  net recorded  during both the three months ended June
30, 1998 and 1999 primarily consists of litigation settlement costs.

     Accretion and preferred dividends on preferred  securities of subsidiaries.
Accretion  and  preferred  dividends on  preferred  securities  of  subsidiaries
increased  $1.6 million,  from $13.6 million for the three months ended June 30,
1998 to $15.2 million for the three months ended June 30, 1999.  The increase is
due  primarily  to the periodic  payment of  dividends  on the 14%  Exchangeable
Preferred Stock Mandatorily  Redeemable 2008 (the "14% Preferred Stock") and the
14 1/4% Exchangeable  Preferred Stock Mandatorily  Redeemable 2009 (the "14 1/4%
Preferred  Stock") in additional  shares of 14%  Preferred  Stock and 14 1/4% of
Preferred Stock.  Accretion and preferred  dividends on preferred  securities of
subsidiaries  recorded  during the three months ended June 30, 1999  consists of
the accretion of issuance  costs ($0.3 million) and the accrual of the preferred
securities  dividends  ($14.9 million)  associated with the 6 3/4%  Exchangeable
Limited Liability Company Preferred Securities  Mandatorily Redeemable 2009 (the
"6  3/4%  Preferred  Securities"),  the  14%  Preferred  Stock  and  the 14 1/4%
Preferred Stock.

     Loss from continuing operations.  Loss from continuing operations increased
$41.4  million,  or 50%,  from $82.4 million for the three months ended June 30,
1998 to $123.8  million  for the three  months  ended  June 30,  1999 due to the
increases in operating costs,  SG&A expenses,  depreciation and amortization and
provision for impairment of long-lived assets, offset by an increase in revenue,
as noted above.

     Net  loss  from  discontinued   operations.   Net  loss  from  discontinued
operations  decreased  $9.7  million or 53%,  from $18.4  million  for the three
months  ended June 30, 1998 to $8.7  million for the three months ended June 30,
1999. Net loss from discontinued  operations for the three months ended June 30,
1998  consists  of the  combined  net  losses  of  Network  Services,  Satellite
Services,  Zycom and NETCOM. Net loss from discontinued operations for the three
months  ended  June 30,  1999  consists  of the  combined  net losses of Network
Services and  Satellite  Services.  Zycom  terminated  its normal  operations on
October  22,  1998  and,   accordingly,   the  Company  reported  no  loss  from
discontinued  operations of Zycom for the three months ended June 30, 1999.  The
Company sold the  operations of NETCOM in February and March 1999. Net loss from
discontinued  operations  for the three months  ended June 30, 1999  includes an
estimated loss on the disposal of Network Services of $8.0 million.

Six Months Ended June 30, 1999 Compared to Six Months Ended June 30, 1998

     Revenue.  Revenue,  which consists solely of revenue from Telecom Services,
increased  $99.3  million,  or 81%, from $122.7 million for the six months ended
June 30, 1998 to $222.0  million for the six months ended June 30,  1999.  Local
services revenue  increased from $52.6 million,  or 43% of revenue,  for the six
months  ended June 30, 1998 to $144.2  million,  or 65% of revenue,  for the six
months ended June 30, 1999. In addition,  local access revenue  includes revenue
of  approximately  $15.1 million and $70.9 million for the six months ended June
30, 1998 and 1999,  respectively,  for reciprocal  compensation  relating to the
transport  and  termination  of local  traffic to ISPs from  customers  of ILECs
pursuant to various interconnection agreements. Special access revenue increased
from $33.7 million, or 27% of revenue, for the six months ended June 30, 1998 to
$46.0  million,  or 21% of  revenue,  for the six months  ended  June 30,  1999.
Switched access  (terminating  long distance) revenue decreased to $21.6 million
for the six months  ended June 30, 1999,  compared to $25.6  million for the six
months  ended June 30,  1998.  The  Company has raised  prices on its  wholesale
switched  services  product in order to improve margins and to de-emphasize  its
wholesale  switched  services.  Revenue  from long  distance  decreased to $10.2
million for the six months  ended June 30, 1999,  compared to $10.9  million for
the six months ended June 30, 1998.  The  decrease in long  distance  revenue is
primarily attributable to the Company's planned attrition of resale access lines
which  had high long  distance  service  penetration  rates.  Revenue  from data
services  did not generate a material  portion of total  revenue  during  either
period.

     Operating costs.  Operating costs, which consists solely of operating costs
from Telecom Services,  increased $24.1 million,  or 27%, from $89.0 million for
the six months  ended June 30, 1998 to $113.1  million for the six months  ended
June 30, 1999.  Additionally,  operating  costs  decreased  as a  percentage  of
revenue  from 73% for the six  months  ended  June  30,  1998 to 51% for the six
months ended June 30, 1999. The increase in operating costs in absolute  dollars
is  attributable  to the increase in volume of local and special access services
and the  increase in network  operating  costs  which  include  engineering  and
operations  personnel  dedicated to the development and launch of local exchange
services.  The  decrease in operating  costs as a  percentage  of revenue is due
primarily  to a greater  volume of higher  margin  services,  principally  local
exchange services.

     Selling, general and administrative expenses. Total SG&A expenses increased
$12.6 million, or 17%, from $73.2 million for the six months ended June 30, 1998
to $85.8  million for the six months  ended June 30, 1999.  Total SG&A  expenses
decreased as a percentage  of revenue from 60% for the six months ended June 30,
1998 to 39% for the six  months  ended  June 30,  1999.  Telecom  Services  SG&A
expenses  increased  from $63.0 million,  or 51% of revenue,  for the six months
ended June 30,  1998 to $76.3  million,  or 34% of  revenue,  for the six months
ended June 30, 1999. The increase in absolute  dollars is 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.  As the
Company begins to benefit from the revenue generated by newly developed services
requiring  substantial  administrative,  selling and marketing  expense prior to
initial  service  offerings,  Telecom  Services has  experienced  declining SG&A
expenses as a percentage of revenue.  Corporate Services SG&A expenses decreased
$0.7 million,  from $10.3 million for the six months ended June 30, 1998 to $9.5
million for the six months ended June 30, 1999,  primarily  due to the Company's
purchase of the corporate  headquarters,  effective  January 1, 1999,  which was
leased under an operating lease during 1998.

     Depreciation and  amortization.  Depreciation  and  amortization  increased
$49.5 million,  or 157%, for the six months ended June 30, 1999, compared to the
six  months  ended June 30,  1998,  primarily  due to  increased  investment  in
depreciable  assets  resulting  from the  continued  expansion of the  Company's
networks  and  services,  in addition to  increased  amortization  arising  from
goodwill  recorded in  conjunction  with three  purchase  business  combinations
completed during the second half of fiscal 1998.

     Provision for  impairment of  long-lived  assets.  For the six months ended
June 30, 1999,  provision for  impairment of long-lived  assets of $29.3 million
relates to the  impairment of software and other  capitalized  costs  associated
with Telecom Services'  in-process  billing and provisioning  system development
projects.  The  provision  for  impairment  of  long-lived  assets  was based on
management's decision to select new vendors for these systems, which vendors are
expected to provide the Company with  billing and  provisioning  solutions  with
improved  functionality and earlier delivery dates at significantly lower costs.
The  Company's  in-process  billing  and  provisioning  systems  were either not
operational or were serving minimal customers at the time management  determined
the carrying value of the underlying assets was not recoverable.

     Other,  net. Other,  net operating costs and expenses  fluctuated from $0.5
million net expense to $0.5 million net income.  Other,  net operating costs and
expenses for the six months ended June 30, 1999 includes  deferred  compensation
expenses  of  $0.4  million,  offset  primarily  by a net  gain on  disposal  of
long-lived  assets of $0.9 million relating  primarily to the sale of certain of
the Company's Federal  Communications  Commission  ("FCC") licenses.  Other, net
operating  costs and expenses  for the six months  ended June 30, 1998  consists
primarily  of a net  loss  on  disposal  of  long-lived  assets  related  to the
write-off  of  certain   installation  costs  of  disconnected   special  access
customers.

     Interest  expense.  Interest  expense  increased $22.8 million,  from $75.9
million for the six months  ended June 30,  1998,  to $98.7  million for the six
months ended June 30, 1999,  which includes  $92.7 million of noncash  interest.
The Company's interest expense increases, and will continue to increase, because
the principal  amount of its  indebtedness  increases until the Company's senior
indebtedness  begins to pay interest in cash,  beginning in 2001.  Additionally,
interest expense increased due to the increase in long-term debt associated with
the Company's purchase of the corporate headquarters, effective January 1, 1998.

     Interest income. Interest income decreased $6.1 million, from $14.0 million
for the six months  ended June 30, 1998 to $7.9 million for the six months ended
June 30,  1999.  The  decrease is  attributable  to the  decrease in cash,  cash
equivalents and short-term investments as the Company funds operating losses and
continues to invest available cash balances in telecommunications  equipment and
other assets.

     Other expense,  net. Other expense, net increased from $0.6 million for the
six months ended June 30, 1998 to $2.3 million for the six months ended June 30,
1999 and primarily  consists of litigation  settlement costs. For the six months
ended  June 30,  1999,  other  expense,  net is offset by the gain on the common
stock of MindSpring which the Company received as partial  consideration for the
sale of the domestic  operations of NETCOM.  The Company sold its  investment in
MindSpring in April 1999.

     Accretion and preferred dividends on preferred  securities of subsidiaries.
Accretion  and  preferred  dividends on  preferred  securities  of  subsidiaries
increased  $3.2  million,  from $26.8  million for the six months ended June 30,
1998 to $30.0  million for the six months ended June 30,  1999.  The increase is
due primarily to the periodic  payment of dividends on the 14%  Preferred  Stock
and the 14 1/4% Preferred Stock in additional  shares of 14% Preferred Stock and
14 1/4% of  Preferred  Stock.  Accretion  and  preferred  dividends on preferred
securities of  subsidiaries  recorded  during the six months ended June 30, 1999
consists of the  accretion of issuance  costs ($0.6  million) and the accrual of
the preferred  securities  dividends ($29.4 million)  associated with the 6 3/4%
Preferred Securities, the 14% Preferred Stock and the 14 1/4% Preferred Stock.

     Loss from continuing operations.  Loss from continuing operations increased
$49.1  million,  or 31%,  from $160.9  million for the six months ended June 30,
1998 to  $210.0  million  for the six  months  ended  June  30,  1999 due to the
increases in operating  costs,  SG&A expenses,  depreciation  and  amortization,
provision for impairment of long-lived assets and interest expense, offset by an
increase in revenue, as noted above.

     Net  loss  from  discontinued   operations.   Net  loss  from  discontinued
operations decreased $32.9 million or 79%, from $41.7 million for the six months
ended June 30, 1998 to $8.8 million for the six months ended June 30, 1999.  Net
loss  from  discontinued  operations  for the six  months  ended  June 30,  1998
consists of the combined  net losses of Network  Services,  Satellite  Services,
Zycom and NETCOM. Net loss from discontinued operations for the six months ended
June 30,  1999  consists  of the  combined  net losses of Network  Services  and
Satellite  Services.  Zycom terminated its normal operations on October 22, 1998
and, accordingly,  the Company reported no loss from discontinued  operations of
Zycom for the six months  ended June 30,  1999.  Since the  Company  expected to
report a gain on the disposition of NETCOM,  the Company deferred the net losses
from operations of NETCOM from November 3, 1998 (the date on which the Company's
board of  directors  adopted  the formal  plan to dispose of the  operations  of
NETCOM) through the dates of the sales and, accordingly, the Company reported no
loss from  discontinued  operations  of NETCOM for the six months ended June 30,
1999.  Net loss from  discontinued  operations for the six months ended June 30,
1999  includes an  estimated  loss on the  disposal of Network  Services of $8.0
million.

     Extraordinary  gain on sales of operations of NETCOM.  The Company reported
an  extraordinary  gain on the sales of the  operations of NETCOM during the six
months  ended  June 30,  1999 of $193.0  million,  net of  income  taxes of $6.4
million.  Offsetting the gain on the sales is approximately $16.6 million of net
losses of  operations  of NETCOM from  November 3, 1998 through the dates of the
sales and $26.0 million of deferred  sales  proceeds from the sale of certain of
the domestic  operating  assets and  liabilities  of NETCOM to  MindSpring.  The
deferred  proceeds  are  recognized  on a  periodic  basis  over the term of the
Company's network capacity agreement with MindSpring.

Liquidity and Capital Resources

     The Company's growth has been funded through a combination of equity,  debt
and lease  financing.  As of June 30,  1999,  the Company had current  assets of
$449.5  million,   including  $265.4  million  of  cash,  cash  equivalents  and
short-term investments available for sale, which exceeded current liabilities of
$160.3 million, providing working capital of $289.2 million. The Company invests
excess  funds   primarily  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.

Net Cash Used By Operating Activities

     The Company's operating activities used $30.9 million and $22.0 million for
the six months  ended  June 30,  1998 and 1999,  respectively.  Net cash used by
operating  activities is primarily due to losses from continuing  operations and
increases  in  receivables,  which are  partially  offset by  changes in working
capital  items and noncash  expenses,  such as  depreciation  and  amortization,
deferred  interest  expense and accretion and preferred  dividends on subsidiary
preferred securities.

     The Company 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.
As the Company provides a greater volume of higher margin services,  principally
local exchange services,  carries more traffic on its own facilities rather than
ILEC  facilities and obtains the right to use unbundled ILEC  facilities,  while
experiencing  decelerating  increases  in  personnel  and  other  SG&A  expenses

                                       35
<PAGE>

supporting  its  operations,  any or all of which  may not  occur,  the  Company
anticipates that net cash used by operating  activities will improve in the near
term.

Net Cash (Used) Provided By Investing Activities

     Investing  activities  used $30.6 million and provided $50.9 million in the
six  months  ended  June  30,  1998 and  1999,  respectively.  Net cash  used by
investing  activities for the six months ended June 30, 1998 primarily  includes
cash  expended for the  acquisition  of property,  equipment and other assets of
$150.0 million,  offset by the proceeds from the sale of corporate  headquarters
of $29.1 million and proceeds from the sale of short-term  investments available
for sale of $96.3 million. Net cash provided by investing activities for the six
months ended June 30, 1999 includes proceeds from the sales of the operations of
NETCOM of $252.9  million and proceeds from the sales of short-term  investments
available for sale and marketable  securities of $51.8  million,  offset by cash
expended for the  acquisition of property,  equipment and other assets of $229.7
million.  The Company will continue to use cash in 1999 and  subsequent  periods
for the  construction of new networks,  the expansion of existing  networks and,
potentially, for acquisitions.  The Company acquired assets under capital leases
of $6.2 million during the six months ended June 30, 1999.

Net Cash Provided (Used) By Financing Activities

     Financing  activities  provided $533.5 million and used $4.8 million in the
six months  ended June 30,  1998 and 1999,  respectively.  Net cash  provided by
financing  activities  for the six months  ended June 30, 1998  includes the net
proceeds  from  the  private  placement  of the 10%  Notes  and 9 7/8%  Notes in
February and April 1998,  respectively.  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 ICG and  ICG  Holdings  (Canada)  Co.  ("Holdings-Canada")  common
shares,   convertible   subordinated  notes,  convertible  preferred  shares  of
Holdings-Canada,  capital lease  financings and various working capital sources,
including  credit  facilities,  in  addition  to the  private  placement  of the
securities  previously  mentioned  and  other  securities  offerings.  Net  cash
provided  (used) by financing  activities for the six months ended June 30, 1998
and 1999 also include  proceeds from the issuance of common stock in conjunction
with the  exercise of options and  warrants  and the  Company's  employee  stock
purchase plan, offset by principal payments on long-term debt and capital leases
and payments of preferred dividends on preferred securities of subsidiaries.

     On August 12,  1999,  ICG  Equipment  and  NetAhead  entered  into a $200.0
million senior secured financing facility (the "Senior Facility")  consisting of
a $75.0  million  term  loan,  a $100.0  million  term loan and a $25.0  million
revolving  line of credit.  As required under the terms of the loan, the Company
borrowed on August 12, 1999 the  available  $75.0  million on the $75.0  million
term loan. The loan bears interest at an annual interest rate of LIBOR plus 3.5%
or the base  rate,  as  defined  in the  credit  agreement,  plus  2.5%,  at the
Company's  option  (10.5% on August 12,  1999).  Quarterly  repayments  commence
September  30, 1999 and  require  quarterly  loan  balance  reductions  of 0.25%
through June 30, 2005 with the remaining outstanding balance to be repaid during
the final three  quarters of the loan term.  The $75.0 million term loan matures
on March 31, 2006. On August 12, 1999, the Company  borrowed $5.0 million on the
$100.0  million term loan,  which is available for borrowing  through August 10,
2000 at an initial  annual  interest rate of LIBOR plus 3.125% or the base rate,
as  defined  in the credit  agreement,  plus  2.125%,  at the  Company's  option
(10.125% on August 12, 1999).  Quarterly  repayments commence September 30, 2002
and require aggregate loan balance  reductions of 25% through June 30, 2003, 35%
through  June 30, 2004 and 40% through June 30,  2005.  The $100.0  million term
loan matures on June 30, 2005.  The $25.0  million  revolving  line of credit is
available  through  the  maturity  date of June 30,  2005 at an  initial  annual
interest  rate of LIBOR plus  3.125% or the base rate,  as defined in the credit
agreement, plus 2.125%, at the Company's option.

     As of June 30, 1999,  the Company had an aggregate of  approximately  $71.8
million  of  capital  lease  obligations  and an  aggregate  accreted  value  of
approximately  $1.7 billion was  outstanding  under the 13 1/2% Senior  Discount
Notes due 2005 (the "13 1/2 % Notes"),  the 12 1/2%  Senior  Discount  Notes due
2006 (the "12 1/2 % Notes"), the 11 5/8% Senior Discount Notes due 2007 (the "11
5/8 % Notes"),  the 10% Notes and the 9 7/8%  Notes.  The 13 1/2% Notes  require
payments of interest to be made in cash commencing  March 15, 2001 and mature on
September 15, 2005. The 12 1/2% Notes require payments of interest to be made in
cash  commencing  November 1, 2001 and mature on May 1, 2006.  The 11 5/8% Notes
require  payments of interest to be made in cash  commencing  September 15, 2002


                                       36
<PAGE>

and mature on March 15, 2007. The 10% Notes require payments of interest in cash
commencing  August 15, 2003 and mature on February  15,  2008.  The 9 7/8% Notes
require  payments of interest in cash commencing  November 1, 2003 and mature on
May 1, 2008. The 6 3/4% Preferred Securities require payments of dividends to be
made in cash through November 15, 2000. In addition, the 14% Preferred Stock and
14  1/4%  Preferred  Stock  require  payments  of  dividends  to be made in cash
commencing June 15, 2002 and August 1, 2001, respectively.  As of June 30, 1999,
the Company had $34.6 million of other indebtedness outstanding. With respect to
senior indebtedness  outstanding on June 30, 1999, the Company has cash interest
payment  obligations of approximately  $113.3 million in 2001, $158.0 million in
2002,  $212.6  million  in 2003 and  $257.2  million  in 2004.  With  respect to
preferred  securities  currently  outstanding,  the  Company  has cash  dividend
obligations of approximately  $4.5 million remaining in 1999 and $8.9 million in
2000,  for which the Company has  restricted  cash  balances  available for such
dividend payments, $10.7 million in 2001 and $35.4 million in 2002 and each year
thereafter  through  2007.  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 capital 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,  would be adversely
affected.

Capital Expenditures

     The Company's  capital  expenditures  of continuing  operations  (including
assets acquired under capital leases and excluding  payments for construction of
the Company's corporate headquarters) were $150.0 million and $235.9 million for
the six  months  ended  June  30,  1998  and  1999,  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  $284.0  million  during  the
remainder of 1999. To facilitate the expansion of its services and networks, the
Company has entered into  equipment  purchase  agreements  with various  vendors
under which the  Company  has  committed  to  purchase a  substantial  amount of
equipment and other assets,  including a full range of switching systems,  fiber
optic cable, network electronics, software and services. If the Company fails to
meet the minimum  purchase level in any given year,  the vendor may  discontinue
certain discounts,  allowances and incentives otherwise provided to the Company.
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.

Other Cash Commitments and Capital Requirements

     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 six months ended June 30,
1999 included elsewhere herein.

     In  view  of the  continuing  development  of the  Company's  products  and
services,  the expansion of existing networks and the construction,  leasing and
licensing of new 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  asset sales,  cash flows
from  operations,  including the  collection of  receivables  from transport and
termination  charges,  vendor financing  arrangements and credit facilities will
provide  sufficient  funds  necessary  for the Company to expand its business as
currently planned and to fund its operations through 2000. Additional sources of
cash may  include  public  and  private  equity  and debt  financings,  sales of
non-strategic assets,  capital leases and other financing  arrangements.  In the
past,  the Company has been able to secure  sufficient  amounts of  financing to
meet its capital 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.

                                       37
<PAGE>
     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  and sales of  non-strategic  assets until the Company  establishes a
sufficient revenue-generating customer base could have a material adverse effect
on the Company's liquidity.

Transport and Termination Charges

     The Company has  recorded  revenue of  approximately  $4.9  million,  $58.3
million and $70.9 million for fiscal 1997,  fiscal 1998 and the six months ended
June  30,  1999,  respectively,  for  reciprocal  compensation  relating  to the
transport  and  termination  of local  traffic to ISPs from  customers  of ILECs
pursuant to various interconnection  agreements. Some of the ILECs have not paid
most of the  bills  they  have  received  from the  Company  and  have  disputed
substantially  all of these  charges based on the belief that such calls are not
local traffic as defined by the various agreements and not subject to payment of
transport  and  termination  charges  under  state and  federal  laws and public
policies.  As a result,  the Company  expects  receivables  from  transport  and
termination  charges will  continue to increase  until these  disputes have been
resolved.

     The  resolution of these  disputes will be based on rulings by state public
utility  commissions and/or by the FCC. To date, there have been favorable final
rulings from 31 state public utility  commissions that ISP traffic is subject to
the payment of reciprocal compensation under current interconnection agreements.
Many of these state  commission  decisions  have been appealed by the ILECs.  To
date,  four federal  district  court  decisions,  one federal  circuit  court of
appeals  decision and one state court decision have been issued  upholding state
commission  decisions  ordering the payment of reciprocal  compensation  for ISP
traffic.  On February 25, 1999, the FCC issued a decision that ISP-bound traffic
is largely  jurisdictionally  interstate  traffic.  The  decision  relies on the
long-standing  federal  policy  that  ISP  traffic,   although  jurisdictionally
interstate,  is treated as though it is local traffic for pricing purposes.  The
decision  also  emphasizes  that because  there are  currently no federal  rules
governing  intercarrier  compensation for ISP traffic,  the  determination as to
whether such traffic is subject to  reciprocal  compensation  under the terms of
interconnection  agreements is properly made by the state  commissions  and that
carriers  are bound by their  interconnection  agreements  and state  commission
decisions regarding the payment of reciprocal  compensation for ISP traffic. The
FCC has initiated a rulemaking  proceeding regarding the adoption of prospective
federal rules for intercarrier  compensation  for ISP traffic.  In its notice of
rulemaking,  the FCC expresses its preference that  compensation  rates for this
traffic  continue to be set by  negotiations  between  carriers,  with  disputes
resolved  by  arbitrations  conducted  by  state  commissions,  pursuant  to the
Telecommunications Act. Since the issuance of the FCC's decision on February 25,
1999, 15 state utility  commissions,  including four states in which the Company
provides  CLEC  services,  have either ruled or  reaffirmed  that ISP traffic is
subject to reciprocal compensation under current interconnection agreements, and
two state  commissions  have declined to apply  reciprocal  compensation for ISP
traffic.

     On May 5, 1999, the Public  Utilities  Commission of Ohio ("PUCO") issued a
decision  affirming  its August  1998  decision  that ISP  traffic is subject to
reciprocal  compensation under the Company's current  interconnection  agreement
with  Ameritech  Corporation  ("Ameritech").  The PUCO also  denied  Ameritech's
request for a stay of its obligation to remit payment to the Company.  After the
PUCO issued the May 5, 1999 ruling,  the Company  received  $43.1 million during
the  three  months  ended  June  30,  1999 for  amounts  owed by  Ameritech  for
reciprocal  compensation.  Ameritech  has filed for judicial  review of the PUCO
decision.  The Company  cannot  predict  the final  outcome on the merits of the
court appeal. Additionally, on June 4, 1999, Southwestern Bell Telephone Company
("SWBT")  remitted  payment  to the  Company  of  $1.8  million  for  reciprocal
compensation  owed to the Company for traffic  from SWBT  customers  in Texas to
ISPs  served by the  Company.  On June 21,  1999,  the  Alabama  Public  Service
Commission ("PSC") issued a decision that BellSouth Corporation ("BellSouth") is
required to pay the Company reciprocal  compensation for ISP traffic.  The PSC's
June 21, 1999  decision  modified  its March 1999  decision  that had found that
reciprocal  compensation  is  owed  for  Internet  traffic  under  certain  CLEC
interconnection  agreements  at issue in the  proceeding.  The June 21, 1999 PSC
decision  held that the  Company  should be treated  the same as the other CLECs
that  participated  in the  proceeding  and for which the Alabama PSC previously
ordered the payment of reciprocal compensation. BellSouth has filed for judicial
review of both the March 4, 1999 and June 21,  1999 PSC  decisions.  On July 26,
1999 the California Public Utilities  Commission  issued a decision  affirming a
previous decision,  issued October 1998, that held that reciprocal  compensation

                                       38
<PAGE>

must be paid by  Pacific  Bell and GTE  California  for the  termination  of ISP
traffic by CLECs under existing  interconnection  agreements.  On July 28, 1999,
the Colorado Public Utilities Commission approved a decision that orders US WEST
Communications,  Inc. ("US WEST") to pay the Company reciprocal compensation for
calls  from US WEST  customers  to ISPs  served  by the  Company.  The  decision
resolves in the  Company's  favor a  complaint  that was filed by the Company in
June 1998.

     The Company has also recorded  revenue of  approximately  $19.1 million and
$7.6  million  for  fiscal  1998  and  the  six  months  ended  June  30,  1999,
respectively,  related to other transport and termination  charges to the ILECs,
pursuant to the Company's interconnection  agreements with these ILECs. Included
in the Company's  trade  receivables  at December 31, 1998 and June 30, 1999 are
$72.8 million and $100.7 million,  respectively,  for all receivables related to
reciprocal  compensation  and  other  transport  and  termination  charges.  The
receivables  balance at June 30, 1999 is net of an allowance of $9.6 million for
disputed amounts.

     As the Company's  interconnection  agreements expire or are extended, rates
for  transport  and  termination  charges  are  being  and will  continue  to be
renegotiated.  Some of the  Company's  agreements  are already  being  affected.
Although the Company's interconnection agreement with BellSouth has expired, the
Company has received  written  notification  from BellSouth that the Company may
continue  operating  under the  expired  interconnection  agreement,  until such
agreement is  renegotiated or arbitrated by the relevant state  commissions.  On
May 27, 1999, the Company filed petitions with the state commissions of Alabama,
Georgia,  North Carolina,  Kentucky,  Tennessee and Florida for arbitration with
BellSouth.  The  arbitration  proceedings  are ongoing in each of these  states.
Additionally,  the Company's  interconnection  agreement with Ameritech recently
was extended from June 15, 1999 to February 15, 2000. The Company's extension of
its  interconnection   agreement  with  Ameritech  includes  reduced  rates  for
transport and termination charges, and the Company expects that its negotiations
and  arbitrations  with  BellSouth  will also affect the rates for transport and
termination  charges  included in its existing  interconnection  agreement  with
BellSouth. The Company's remaining interconnection agreements expire in 1999 and
2000,  and the Company has commenced  renegotiations  with the ILECs.  While the
Company  believes that all revenue recorded through June 30, 1999 is collectible
and that future revenue from transport and termination  charges billed under the
Company's current interconnection  agreements will be realized,  there can be no
assurance that future  regulatory and judicial  rulings will be favorable to the
Company,  or that different pricing plans for transport and termination  charges
between  carriers  will  not  be  adopted  when  the  Company's  interconnection
agreements  are  renegotiated  or  arbitrated,  or  as a  result  of  the  FCC's
rulemaking  proceeding  on future  compensation  methods.  In fact,  the Company
believes  that  different  pricing  plans will be  considered  and adopted,  and
although the Company expects that revenue from transport and termination charges
likely will  decrease as a percentage  of total  revenue from local  services in
periods  after  the  expiration  of  current  interconnection   agreements,  the
Company's  local  termination  services  still will be required by the ILECs and
must be provided  under the  Telecommunications  Act,  and likely will result in
increasing  volume in minutes  due to the  growth of the  Internet  and  related
services markets. The Company expects to negotiate  reasonable  compensation and
collection terms for local termination services,  although there is no assurance
that such compensation will remain consistent with current levels. Additionally,
the Company  expects to supplement  its current  operations  with  revenue,  and
ultimately  EBITDA,  from new services  offerings  such as RAS and DSL services,
however,  the Company may or may not be successful in its efforts to deploy such
services profitably.

Year 2000 Compliance

Importance

     Many  computer  systems,   software   applications  and  other  electronics
currently  in use  worldwide  are  programmed  to accept  only two digits in the
portion of the date field which  designates  the year.  The "Year 2000  problem"
arises because these systems and products cannot properly  distinguish between a
year that begins with "20" and the familiar  "19." If these systems and products
are not modified or replaced,  many will fail,  create erroneous  results and/or
may cause interfacing systems to fail.

     Year 2000  compliance  issues are of  particular  importance to the Company
since its operations rely heavily upon computer systems,  software  applications
and other electronics  containing  date-sensitive  embedded technology.  Some of
these  technologies were internally  developed and others are standard purchased
systems which may or may not have been  customized for the Company's  particular
application.  The Company also relies heavily upon various vendors and suppliers

                                       39
<PAGE>

that are themselves very reliant on computer systems,  software applications and
other electronics containing  date-sensitive embedded technology.  These vendors
and suppliers include: (i) ILECs and other local and long distance carriers with
which the Company has  interconnection or resale agreements;  (ii) manufacturers
of the hardware and related  operating systems that the Company uses directly in
its operations;  (iii) providers that create custom software  applications  that
the  Company  uses  directly in its  operations;  and (iv)  providers  that sell
standard  or custom  equipment  or  software  which allow the Company to provide
administrative support to its operations.

Strategy

     The  Company's  approach to addressing  the  potential  impact of Year 2000
compliance issues is focused upon ensuring,  to the extent reasonably  possible,
the  continued,  normal  operation  of  its  business  and  supporting  systems.
Accordingly, the Company has developed a four-phase plan which it is applying to
each functional category of the Company's computer systems and components.  Each
of the Company's computer systems,  software  applications and other electronics
containing  date-sensitive  embedded  technology  is included  within one of the
following four functional categories:

     o    Networks  and  Products,  which  consists  of all  components  whether
          hardware,  software  or  embedded  technology  used  directly  in  the
          Company's  operations,  including  components  used  by the  Company's
          circuit  and data  switches  and  collocation  and  telecommunications
          products;

     o    IT  Systems,  which  consists  of all  components  used to support the
          Company's operations, including provisioning and billing systems;

     o    Building  and  Facilities,  which  consists  of  all  components  with
          embedded  technology  used  at the  Company's  corporate  headquarters
          building  and other leased  facilities,  including  security  systems,
          elevators and internal use telephone systems;

     o    Office  Equipment,   which  consists  of  all  office  equipment  with
          date-sensitive embedded technology.

     For each of the  categories  described  above,  the Company is applying the
following four-phase approach to identifying and addressing the potential impact
of Year 2000 compliance issues:

     o    Phase I - Assessment
          During  this  phase,  the  Company's  technology  staff  performed  an
          inventory of all  components  currently  in use by the Company.  Based
          upon this inventory,  the Company's business executives and technology
          staff jointly classified each component as a "high," "medium" or "low"
          priority item,  determined  primarily by the relative  importance that
          the  particular   component  has  to  the  Company's  normal  business
          operations, the number of people internally and externally which would
          be affected by any failure of such  component and the  interdependence
          of such component with other  components  used by the Company that may
          be of higher or lower priority.

          Based upon such classifications, the Company's business executives and
          information  technology  staff jointly set desired levels of Year 2000
          readiness  for  each  component   inventoried,   using  the  following
          criteria, as defined by the Company:

          -    Capable,  meaning that such computer  system or component will be
               capable of managing and expressing calendar years in four digits;

          -    Compliant,  meaning  that  the  Company  will be able to use such
               component  for the purpose  for which the Company  intended it by
               adapting to its ability to manage and express  calendar  years in
               only two digits;

          -    Certified,  meaning that the Company has received testing results
               to  demonstrate,   or  the  vendor  or  supplier  is  subject  to
               contractual terms which requires, that such component requires no
               Year 2000  modifications  to manage and express calendar years in
               four digits; or

                                       40
<PAGE>

          -    Non-critical,  meaning  that the  Company  expects  to be able to
               continue to use such component  unmodified or has determined that
               the estimated  costs of  modification  exceed the estimated costs
               associated with its failure.

          The Company has completed all areas of Phase I.

     o    Phase II - Remediation
          During  this  phase,   the  Company  is  developing  and  executing  a
          remediation  plan for each component  based upon the priorities set in
          Phase I.  Remediation may include  component  upgrade,  reprogramming,
          replacement,  receipt of vendor and  supplier  certification  or other
          actions as deemed necessary or appropriate.

     o    Phase III - Testing
          During this phase,  the Company is  performing  testing  sufficient to
          confirm  that the  component  meets  the  desired  state of Year  2000
          readiness.  This phase  consists  of: (i)  testing  the  component  in
          isolation,  or unit testing;  (ii) testing the component  jointly with
          other components,  or system testing; and (iii) testing interdependent
          systems, or environment testing.

     o    Phase IV - Implementation
          During  the  last  phase,  the  Company  is  implementing  each act of
          remediation  developed  and  tested  for  each  component,  as well as
          implementing  adequate  controls to ensure that  future  upgrades  and
          changes to the Company's  computer  systems,  for operational  reasons
          other than Year 2000 compliance,  do not alter the Company's Year 2000
          state of readiness.

Current State of Readiness

     The Company has either already completed or has commenced all of the phases
within  its Year 2000  compliance  strategy  for each of its  functional  system
categories,  as shown by the table set forth  below.  Since the  Company has not
waited until the  completion of a phase for all functional  category  components
together  before  commencing  the next phase,  the  information  set forth below
represents  only a general  description of the phase status for each  functional
category.  For systems  and  products  which the  Company  intends to abandon or
replace prior to January 1, 2000, the Company has currently  terminated all Year
2000 compliance efforts.

Costs

     The Company expenses all incremental  costs to the Company  associated with
Year 2000  compliance  issues as incurred.  Through  June 30,  1999,  such costs
incurred were  approximately  $1.1 million,  consisting  of  approximately  $0.6
million of replacement  hardware and software and approximately  $0.5 million of
consulting fees and other miscellaneous costs of Year 2000 compliance  reference
and planning  materials.  The Company has also incurred  certain internal costs,
including  salaries and benefits for employees  dedicating  various  portions of
their time to Year 2000 compliance  issues,  of which costs the Company believes
has not exceeded $0.5 million  through June 30, 1999.  The Company  expects that
total  future  incremental  costs  of  Year  2000  compliance  efforts  will  be
approximately $3.8 million,  consisting of $2.3 million in consulting fees, $1.5
million in  replacement  hardware and software  and other  miscellaneous  costs.
These  anticipated  costs have been included in the Company's fiscal 1999 budget
and  represent   approximately  4%  of  the  Company's   budgeted  expenses  for
information  technology  through fiscal 1999. Such cost estimates are based upon
presently available information and may change as the Company continues with its
Year 2000 compliance plan. The Company intends to use cash on hand for Year 2000
compliance costs, as necessary.

Risk, Contingency Planning and Reasonably Likely Worst Case Scenario

     While the Company is heavily  reliant upon its computer  systems,  software
applications and other electronics containing date-sensitive embedded technology
as part of its  business  operations,  such  components  upon which the  Company
primarily  relies were developed with current  state-of-the-art  technology and,
accordingly, the Company's four-phase approach has demonstrated that many of its
high-priority  systems do not present material Year 2000 compliance  issues. For
computer  systems,   software  applications  and  other  electronics  containing
date-sensitive  embedded technology that have met the Company's desired level of
Year 2000  readiness,  the Company is using its  existing  contingency  plans to
mitigate or eliminate  problems it may  experience  if an  unanticipated  system
failure were to occur.  For components  that have not met the Company's  desired
level of  readiness,  the Company  will develop a specific  contingency  plan to
determine the actions the Company would take if such component failed.

     The Company believes that a reasonably likely worst case scenario of a Year
2000 compliance  failure could include the temporary failure of a minimal number
of  operating  systems,   despite  the  Company's   execution  and  satisfactory
completion of its comprehensive Year 2000 compliance plan.  However,  under this
scenario,  the Company also believes that any such failed  systems or components
would be fully  recovered  within a short  period  subsequent  to  failure  and,
accordingly,  the Company does not expect to experience any  significant or long
term  operational  disruption  as a result  of the  failure  of any  systems  or
components directly within the Company's control.

     The  Company  acknowledges  the  possibility  that the  Company  may become
subject  to  potential  claims by  customers  if the  Company's  operations  are
interrupted  for an  extended  period of time.  However,  it is not  possible to
predict either the  probability of such  potential  litigation,  the amount that
could  be in  controversy  or upon  which  party a court  would  place  ultimate
responsibility for any such interruption.

     The Company  views Year 2000  compliance  as a process  that is  inherently
dynamic and will change in response to changing circumstances. While the Company
believes  that through  execution and  satisfactory  completion of its Year 2000
compliance strategy its computer systems,  software applications and electronics
will be Year  2000  compliant,  there  can be no  assurance  until the Year 2000
occurs that all systems and all interfacing technology when running jointly will
function  adequately.   Additionally,   there  can  be  no  assurance  that  the
assumptions  made by the Company within its Year 2000  compliance  strategy will
prove to be correct, that the strategy will succeed or that the remedial actions
being  implemented  will be able to be completed by the time  necessary to avoid
system or  component  failures.  In  addition,  disruptions  with respect to the
computer systems of vendors or customers,  which systems are outside the control
of the Company,  could impair the Company's ability to obtain necessary products
or services to sell to its  customers.  Disruptions  of the  Company's  computer
systems, or the computer systems of the Company's vendors or customers,  as well
as the cost of avoiding such disruption, could have a material adverse effect on
the Company's financial condition and results of operations.

ITEM 3.       QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

     The Company's financial position and cash flows are subject to a variety of
risks in the normal course of business,  which include  market risks  associated
with  movements  in interest  rates and equity  prices.  The  Company  routinely
assesses  these risks and has  established  policies and  business  practices to
protect against the adverse effects of these and other potential exposures.  The
Company does not, in the normal  course of business,  use  derivative  financial
instruments for trading or speculative purposes.

Interest Rate Risk

     The Company's  exposure to market risk  associated with changes in interest
rates relates  primarily to the Company's  investments in marketable  securities
and its senior indebtedness.

     The Company invests  primarily in high grade short-term  investments  which
consist of money market instruments,  commercial paper, certificates of deposit,
government  obligations and corporate  bonds,  all of which are considered to be
available  for sale  and  generally  have  maturities  of one year or less.  The
Company's short term investment  objectives are safety,  liquidity and yield, in
that order. As of June 30, 1999, the Company had approximately $265.3 million in
cash,  cash  equivalents  and  short-term  investments  available for sale, at a
weighted  average fixed interest rate of 4.83% for the six months ended June 30,
1999. A hypothetical  10%  fluctuation in market rates of interest would cause a
change in the fair value of the Company's investment in marketable securities at
June 30, 1999 of approximately $0.7 million and, accordingly,  would not cause a
material impact on the Company's  financial  position,  results of operations or
cash flows.

     At June 30, 1999,  the Company's  indebtedness  included $1.7 billion under
the 13 1/2% Notes, 12 1/2% Notes, 11 5/8% Notes,  10% Notes and 9 7/8% Notes and
$491.9 million under the 14 1/4% Preferred Stock, 14% Preferred Stock and 6 3/4%
Preferred  Securities.  These  instruments  contain  fixed  annual  interest and
dividend rates,  respectively,  and, accordingly,  any change in market interest
rates  would  have no impact on the  Company's  financial  position,  results of
operations or cash flows.  Future increases in interest rates could increase the
cost of any new  borrowings  by the Company.  The Company does not hedge against
future changes in market rates of interest.

     On  August  12,  1999,  the  Company  entered  into  the  Senior  Facility,
consisting of two term loans and a revolving  line of credit.  All components of
the Senior Facility bear variable annual rates of interest,  based on changes in
LIBOR,  the  Royal  Bank of  Canada  prime  rate  and the  federal  funds  rate.
Consequently,  additional  borrowings under the Senior Facility and increases in
LIBOR,  the Royal  Bank of Canada  prime  rate and the  federal  funds rate will
increase the  Company's  indebtedness  and may increase the  Company's  interest
expense in future periods. Additionally, under the terms of the Senior Facility,
the Company is required to hedge the interest rate risk on $100.0 million of the
Senior Facility if LIBOR exceeds 9.0% for 15 consecutive  days. As of August 13,
1999, the Company had $80.0 million outstanding under the Senior Facility.

Equity Price Risk

     On February  17,  1999,  the  Company  completed  the sale of the  domestic
operations of NETCOM to  MindSpring,  in exchange for a combination  of cash and
376,116 shares of common stock of MindSpring, valued at approximately $79.76 per
share, or $30.0 million, at the time of the transaction. Through April 16, 1999,
the Company bore some risk of market price  fluctuations  in its  investment  in
MindSpring.  In order to  mitigate  the risk  associated  with a decrease in the
market value of the Company's investment in MindSpring, the Company entered into
a hedging contract. In April 1999, the Company sold its investment in MindSpring
for net proceeds of approximately $30.4 million.  The Company recorded a gain on
its investment in MindSpring of  approximately  $0.4 million in its statement of
operations  for the six months  ended June 30,  1999.  The hedging  contract was
terminated upon the sale of the common stock of MindSpring.

     On March 30, 1999, the Company purchased,  for approximately  $10.0 million
in cash, 454,545 shares of NorthPoint  Preferred Stock. The NorthPoint Preferred
Stock has no voting rights and is ultimately  convertible into a voting class of
common stock of NorthPoint, at an exchange price which represents a discount, as
provided in the relevant documentation,  to the initial public offering price of
NorthPoint's common stock. The Company is restricted from selling the NorthPoint

                                       43
<PAGE>

Preferred  Stock  or  securities  obtained  upon  conversion  of the  NorthPoint
Preferred Stock until March 23, 2000.  Accordingly,  the Company will be subject
to the  effects  of  fluctuations  in the  fair  value  of the  common  stock of
NorthPoint  until  such time when the  Company is  permitted  to  liquidate  its
investment  in  NorthPoint.  Although  changes in the fair  market  value of the
common stock of  NorthPoint  may affect the fair market  value of the  Company's
investment in NorthPoint  and cause  unrealized  gains or losses,  such gains or
losses will not be realized until the securities are sold.

                                       9
<PAGE>

of payment in full at the  following  rates of interest  (the "Interest  Rate"):
during the first Loan  Year,  at the rate of  fourteen  and seven  thousand  six
hundred eighty-six ten thousandths  percent (14.7686%) per annum; and during the
second Loan Year and each Loan Year  thereafter,  at a rate of interest equal to

that will accrue  during such month  against the  principal  sum of the Loan, as
provided in the Note. So long as no Event of Default has occurred,  each monthly
installment  paid under the Note shall be applied to accrued  interest  accruing
during the applicable month.

     3.3  Computations.  All computations of interest payable hereunder shall be
on the basis of a 360-day year of twelve 30-day months and, for partial  months,
the actual days elapsed.

     Section 4. Late Charges; Prepayment.

     4.1 Late Charges. If any installment under the Note is not paid on the date
due,  such  installment  shall bear interest at the lesser of five hundred basis
points (500) in excess of the prime or  reference  rate  announced  from time to
time by Bank of America NT&SA or twelve  percent  (12%) per annum,  from the due
date until such installment is paid. In addition, Borrower shall pay to Lender a
late charge equal to six percent (6%) of the amount of any installment under the
Note that is not paid within five (5) Business  Days of the date due. As long as
an Event of Default  under this  Agreement,  the Note or any other Loan Document
exists,  and from and after maturity of the Loan,  whether or not resulting from
acceleration,  the entire unpaid  balance of the principal sum of the Note shall
bear interest at the Default Rate.

     4.2  Prepayment.  Except as  expressly  provided  to the  contrary  in this
Agreement,  Borrower  shall  have no right,  at any time,  to prepay the Note in
whole or in part.  Borrower  agrees  that every  payment  of any  portion of the
unpaid  balance of the  principal sum of the Note before the Maturity Date shall
constitute a prepayment under the Note, whether such payment occurs voluntarily,
involuntarily,  or by acceleration of the maturity of the indebtedness evidenced
by the Note by Lender.  Borrower  further agrees that,  upon any such payment of
the Note before the Maturity Date,  Borrower  shall,  with such payment,  pay to
Lender a  prepayment  charge  determined  in  accordance  with this Section 4.2.
Without  limiting the foregoing,  following any  acceleration of the maturity of
the indebtedness evidenced by the Note, such prepayment charge shall be included

                                       10
<PAGE>

in the total  amount  due to Lender at any  foreclosure  sale  under the Deed of
Trust and any  tender  of  payment  of the  indebtedness  evidenced  by the Note
before,  at or after any foreclosure  sale under the Deed of Trust shall include
such  prepayment  charge.  The prepayment  charge shall be equal to five percent
(5%) of the entire  unpaid  balance of the  principal  sum of the Note as of the
prepayment  date.  Borrower  agrees  that  material  individual  weight  to  the
consideration  in this  transaction has been given for the foregoing  waiver and
agreement,   and  Borrower  shall  be  estopped  from  claiming  hereafter  that
Borrower's  agreement  to pay such  prepayment  charge in  accordance  with this
Agreement is invalid or unenforceable in any respect for any reason.

     4.3  Permitted  Prepayment.   Notwithstanding   anything  to  the  contrary
contained  herein,  Borrower  may  prepay  all,  but not less than  all,  of the
principal  and interest  outstanding  under the Note prior to the Maturity  Date
without paying the  prepayment  charge upon the occurrence of either one or both
of the following events:

               (a)  the  closing  of the  option  to  purchase  the  partnership
          interests  of  General  Partner  or the  option to  purchase  the Real
          Property  pursuant  to Articles X and XI of the  Borrower  Partnership
          Agreement; or

          16.1  of  the  Lease  dated  January  15,  1998,  between  Tenant  and
          Borrower's  predecessor,  following  a  condemnation  or  exercise  of
          eminent domain power.

Any prepayment  that occurs pursuant to subsection 4.3 (a) shall be effective as
of the  first  day of the  month in which the  prepayment  is made,  unless  the
purchase  option is  exercised  as a result of the Put Option (as defined in the
Borrower Partnership Agreement), in which case the prepayment shall be effective
on the date paid.

     Section 5. Manner of Payment.  All payments made hereunder shall be made in
accordance with the provisions  hereof without setoff or counterclaim as against
Lender,  in lawful money of the United States of America,  free and clear of and
without  deduction for any taxes, fees or other charges of any nature whatsoever
imposed by any taxing authority.

<PAGE>

Documents as provided herein, Borrower represents and warrants to Lender that as

     7.1 Due  Authorization.  Borrower is a limited  partnership duly formed and
validly  existing  under the laws of the State of Colorado,  with the  requisite
partnership  power and  authority  to own its  properties,  enter  into the Loan
Documents  and  consummate  the  Transactions;  and  Borrower is qualified to do
business in Colorado and each other  jurisdiction  in which its  properties  are
located or where its  ownership,  leasing or  operation  of its  property or the
conduct of its business requires such qualification.

     7.2  Enforceability.  The Loan Documents to which it is a party executed on
or before the Closing Date by Borrower have been duly  authorized,  executed and
delivered  on behalf of Borrower  and  constitute  the legal,  valid and binding
obligations  of  Borrower  enforceable  against  it  in  accordance  with  their
respective terms,  subject to the effect of applicable  bankruptcy,  insolvency,
reorganization,  arrangement,  moratorium  or other  similar laws  affecting the
rights of creditors generally.

     7.3 Restricted Activities. The Borrower Partnership Agreement provides that
the only  purposes of Borrower are to (i)  purchase,  hold title to and operate,
lease and otherwise deal directly or indirectly,  with the Property, (ii) borrow
the  Indebtedness  evidenced  by the Note  and  other  Indebtedness  that is not
prohibited under Section 9.1 hereof,  (iii) give security for the Note and other
Indebtedness  that is not prohibited  under Section 9.1 hereof,  (iv) enter into
contractual  arrangements  for the  management and operation of the Property and
otherwise in  furtherance  of the purposes of Borrower,  (v) sell,  exchange and
refinance  the Property  and (vi) engage in such  activities  and exercise  such
other powers permitted to limited  partnerships  under the laws of Delaware that
are  necessarily  incident to the foregoing  purposes or necessary to accomplish
the foregoing purposes.  The Borrower  Partnership  Agreement also provides that
only General  Partner and Limited Partner acting together may commence or file a
bankruptcy petition or reorganization  proceeding or similar proceeding by or on
behalf of Borrower under any federal or state law or any informal reorganization
or liquidation,  including any arrangement for the benefit of creditors,  or any
similar proceeding by or on behalf of Borrower.

     7.4  Borrower  Obligations.  Borrower  (i) believes it will be able to fund
from its own assets  (including its initial working capital  reserve) all of its
activities,  expenses and  liabilities,  (ii)  intends to pay its own  operating
expenses and  liabilities  from its own funds,  and (iii) has at all times since
its formation  identified itself, in all dealings with the public, under its own
name  and  as a  separate and  distinct entity, and has not identified itself as

                                       14
<PAGE>

being a division or a part of any other Person,  or identified  any other Person
as being a division or a part of Borrower or General Partner.

     7.5 General Partner.  General Partner is a limited liability company,  duly
organized and validly  existing  under the laws of Colorado,  with the requisite
corporate  power and authority to enter into the Loan  Documents and  consummate
the Transactions and to own its properties and conduct its business; and General
Partner is qualified to do business in Colorado and each other  jurisdiction  in
which its properties are located or where its ownership, leasing or operation of
its property or the conduct of its business requires such qualification. General
Partner is the sole General Partner of Borrower.

     7.6  Transactions  with  Affiliates.  Except as disclosed in Schedule  7.6,
Borrower  has not  purchased,  acquired or leased any  property  from,  or sold,
transferred  or leased any  property  to, or loaned or advanced any money to, or
borrowed any money from, or guaranteed any obligation of, or acquired any stock,
obligations,  or  securities  of, or entered  into any  merger or  consolidation
agreement, or any management or similar agreement with, any Affiliate of General
Partner,  or  entered  into any other  transaction  or  arrangement  or made any
payment to (including on account of any management fees,  services fees,  office
charges,  consulting fees, technical services charges or tax sharing charges) or
otherwise  dealt with,  in the  ordinary  course of business or  otherwise,  any
Affiliate  of General  Partner on terms  other  than  arm's-length  commercially
reasonable terms.

     7.7 Employees. Borrower has no employees.

     7.8 No Violation.  Neither the  execution,  delivery or  performance of any
Loan Document nor the consummation of any of the  Transactions  violates or will
violate the Borrower Partnership  Agreement or the charter or by-laws of General
Partner or Guarantor or violates,  conflicts with or constitutes a default under
any  agreement  to which  any of them is a party or by which  any or them or the
Property is bound,  violates any  Requirements  of Law to which  Borrower or the
Property is subject or will result in the  imposition  of a Lien on the Property
other than  Permitted  Exceptions.  None of the  Transactions  will  result in a
violation of Section 7 of the  Securities  Exchange Act of 1934, as amended,  or
any regulations issued pursuant thereto, including Regulations G, T, U, and X of
the Board of Governors of the Federal Reserve System, 12 C.F.R., Chapter II.

     7.9 Consents. No consents, approvals, filings, permits or notices of, from,
with or to any Person are  required on the part of Borrower  or  Guarantor  that
have not been duly obtained,  made or given,  as the case may be (a) for the due
execution  and delivery of each of the Loan  Documents to which it is a party or
(b) for the  performance  of the Loan  Documents in accordance  with their terms
(except for obtaining approvals or  permits from any  Governmental  Authority to

                                       15
<PAGE>

construct tenant  improvements or other  construction  work at or about the Real
Property  or for other  future  actions  consent  to which are  contemplated  or
required by the Loan Documents) and  consummation of, or otherwise in connection
with, any of the Transactions.

     7.10 Solvency.  None of the Transactions  will be or have been made with an
actual  intent to hinder,  delay or defraud any present or future  creditors  of
Borrower or Guarantor,  and neither Borrower,  Guarantor nor General Partner is,
nor will be, rendered  insolvent by the Transactions,  and Borrower has received
fair  consideration and reasonably  equivalent value in good faith for the grant
of the Lien  created  by the Deed of  Trust.  Each of  Borrower,  Guarantor  and
General  Partner  is  able to pay  its  debts  as  they  become  due,  including
contingent obligations likely to become due.

     7.11 Delinquent  Property Liens. Except for claims that are being contested
in accordance  with the Deed of Trust or that are not material in amount or that
constitute or will constitute  Permitted  Exceptions,  to the best of Borrower's
knowledge  there  is  no  delinquent  Imposition,   sewer  rent,  water  charge,
assessment or other outstanding charge against the Real Property; and, except as
shown in the Title  Policy,  to the best of  Borrower's  knowledge  there are no
mechanics' or similar Liens or, to the best of Borrower's knowledge,  claims for
overdue  payment for labor or material  affecting  the Real Property that are or
could  become  Liens prior to, or equal with,  the Lien of the Deed of Trust and
there  are no  mechanics'  or  similar  Liens  or,  to the  best  of  Borrower's
knowledge,  claims  affecting  the Real  Property  that have not been insured or
endorsed over by the Title Policy.

     7.12 Defenses. Except for the effect of applicable bankruptcy,  insolvency,
reorganization,  arrangement, moratorium or similar laws affecting the rights of
creditors  generally,  the Loan  Documents are not subject to any valid right of
rescission,  setoff, abatement,  diminution,  counterclaim or defense as against
Lender and its  successors  and assigns in  interest,  including  the defense of
usury,  and the  operation  of any of the  terms of the Loan  Documents,  or the
proper exercise of any right thereunder, will not render the Loan unenforceable,
in whole or in part, or subject to any right of rescission,  setoff,  abatement,
diminution, counterclaim or defense, including the defense of usury, and neither
Borrower  nor  Guarantor  has  taken  any  action  that  would  give rise to the
assertion  of any of the  foregoing  and no such  right of  rescission,  setoff,
abatement, diminution,  counterclaim or defense, including the defense of usury,
has been asserted with respect thereto.

     7.13 Lien Priority.  Upon recording,  the Deed of Trust shall  constitute a
valid and enforceable first Lien and perfected security interest on the Property
granted by Borrower in favor of Lender,  including  all  buildings  and fixtures
that  constitute  part of the Property under  applicable law, and all additions,

                                       16
<PAGE>

alterations  and  replacements  made at any time with respect to the  foregoing,
subject only to Permitted Exceptions.

     7.14 Improvements. To the best of Borrower's knowledge, except as disclosed
in the Title Policy, all improvements  comprising a portion of the Real Property
lie wholly within the boundary and building restriction lines of the Land and no
improvements  on  adjoining  properties  encroach  upon  any of the  Land in any
respect except as shown in the Title Policy, on the survey or in Schedule 7.14.

     7.15 Casualty;  Condemnation. The Real Property is free of waste and of any
damage involving loss or destruction with a repair cost in excess of two hundred
fifty thousand dollars ($250,000), and there is no proceeding pending or, to the
best of  Borrower's  knowledge,  threatened,  for the  Taking of any of the Real
Property.

     7.16 Zoning and Other Laws.  To the best of Borrower's  knowledge,  the use
and  operation  of  the  Real  Property,  separate  and  apart  from  any  other
properties,  constitutes a legal use under  applicable  zoning  regulations  and
complies in all material  respects with all applicable  Requirements  of Law and
all applicable Insurance Requirements.

     7.17  Leases.  The ICG Lease is in full  force and the  landlord  is not in
default thereunder. The ICG Lease is the only lease, sublease or other occupancy
agreement encumbering the Property, and Tenant is the only tenant,  subtenant or
occupant of the Property. To the best of Borrower's knowledge,  Tenant is not in
default under the ICG Lease.

     7.18 Tenant Estoppels.  Borrower has delivered to Lender an original tenant
estoppel certificate executed by Tenant with respect to the ICG Lease.

     7.19  Litigation.  Except  as set  forth  on  Schedule  7.19,  no  material
litigation,   investigation  or  proceeding  before  any  court,  arbitrator  or
Governmental Authority,  agency or subdivision is pending or, to Borrower's best
knowledge,  threatened,  against  Borrower  or  Guarantor  or,  to the  best  of
Borrower's knowledge, relating to any of the Real Property.

     7.20  Brokerage  and Other Fees.  No brokerage or other fee,  commission or
compensation  is or will  become due and payable by  Borrower  or  Guarantor  in
connection with the Transactions.

     7.21 Investment Company. Neither Borrower nor Guarantor is now required nor
will it (by  reason  of this  Agreement)  be  required  to  register  under  the
Investment Company Act of 1940, as amended.

     7.22 Other Agreements. To the best of Borrower's knowledge, no party to any
deed,  restriction,  covenant or similar instrument that constitutes a Permitted
Exception  in respect  of the Real  Property  is in  default of its  obligations

                                       17
<PAGE>

thereunder  except for such  defaults  that in the  aggregate  (if such defaults
remained uncured) do not or will not have a Material Adverse Effect.

     Section 8.  Affirmative  Covenants.  Borrower  hereby  covenants and agrees
that, so long as the Loan remains  unpaid or any other amount is owing to Lender
under any of the Loan Documents or the Real Property remains subject to the Lien

                      ASSUMPTION AND MODIFICATION AGREEMENT


     THIS ASSUMPTION AND MODIFICATION AGREEMENT ("Agreement") is entered into as
of the  1st day of May  1999,  by and  among  ICG  SERVICES,  INC.,  a  Delaware
corporation  ("Grantor"),  whose address is 161 Inverness Drive West, Englewood,
Colorado 80112, ICG 161, L.P., a Delaware limited partnership ("Grantee"), whose
address is 161  Inverness  Drive West,  Englewood,  Colorado  80112,  and TRINET
REALTY CAPITAL,  INC., a Maryland  corporation  ("Lender")  whose address is One
Embarcadero Center, 33rd Floor, San Francisco, California 94111.

                              W I T N E S S E T H:

     WHEREAS,  Grantor is the owner of certain real property located in Arapahoe
County,  Colorado, more particularly described in Exhibit A attached hereto (the
"Premises"); and

     WHEREAS, Lender previously made a loan to Grantor in the original principal
amount of thirty-three  million  seventy-six  thousand seven hundred  fifty-four
dollars  ($33,076,754) (the "Loan"),  which Loan is evidenced by a Note executed
by Grantor in favor of Lender dated as of January 1, 1999,  in the amount of the
Loan (the "Note"),  and which Note is secured by, among other things,  a Deed of
Trust,  Assignment of Rents and Security  Agreement  dated as of January 1, 1999
(as amended from time to time, the "Deed of Trust"),  encumbering  the Premises,
executed  by  Grantor,  in favor  of the  Public  Trustee  of  Arapahoe  County,
Colorado,  as trustee, for the benefit of Lender, said Deed of Trust recorded in
the  Official   Records  of  Arapahoe   County,   Colorado,   as  Reception  No.
_________________; and

     WHEREAS, Lender is the owner and holder of the indebtedness and obligations
secured by the Deed of Trust (the "Secured Indebtedness"); and

     WHEREAS, Grantor is the current owner of the Premises; and

     WHEREAS,  Grantor  wishes to convey the Premises to Grantee  subject to the
Deed of Trust; and
<PAGE>

     WHEREAS, the Deed of Trust prohibits Grantor from conveying the Premises to
Grantee without the prior written consent of Lender; and

     WHEREAS,  Lender is willing to consent to the  proposed  conveyance  of the
Premises to Grantee and the  assumption by Grantee of the Secured  Indebtedness,
subject to certain  terms and  conditions,  including  but not  limited to those
terms and conditions set forth herein;

     NOW, THEREFORE, in consideration of the provisions hereof, as an inducement
to cause Lender to consent to the proposed  conveyance,  and for other  valuable
consideration,  the receipt and  sufficiency  of which are  acknowledged,  it is
agreed as follows:

     (A) Capitalized terms used herein,  but not otherwise  defined,  shall have
the meaning given them in the Deed of Trust.

     (B)  Consent to  Transfer.  Lender  hereby  consents to the  conveyance  by
Grantor to Grantee of Grantor's  interest in the  Premises.  Except as expressly
provided  herein or in the Loan  Documents (as defined  below),  such consent by
Lender  shall not  constitute  a consent  to any  further  or  subsequent  sale,
transfer, disposition or encumbering of any kind whatsoever, by deed of trust or
otherwise,  of the Mortgaged Property,  or any part thereof or interest therein,
or waive the necessity of further  consent from Lender  whenever such consent is
required pursuant to the Loan Documents.

     (C) Amount of Indebtedness.  Lender warrants,  as of the date hereof,  that
the outstanding principal balance under the Note is $33,076,754 and that Grantor
is not in default under the Loan Documents.

     (D) Assignment of the Loan;  Assumption by Grantee.  Effective as of May 1,
1999 (the  "Transfer  Date"),  Grantor  assigns to Grantee all of such Grantor's
obligations,  rights,  powers,  equities,  remedies,  and  interests in, to, and
arising out of the Loan,  together with the Loan Documents,  to have and to hold
the obligations,  rights, powers,  equities,  remedies, and interests of Grantor
in,  to,  and  arising  out of the Loan and Loan  Documents  unto  Grantee,  its
permitted  successors  and  assigns,  from and after the date hereof for all the
remaining  duration  of the Loan,  subject  to the  covenants,  conditions,  and
provisions  of such Loan as provided  in the Note and the other Loan  Documents.
Effective as of the Transfer Date,  Grantee assumes Grantor's  liability for the
payment of the Secured  Indebtedness  and all of the obligations of Grantor with
respect to the Loan,  including but not limited to the  obligations set forth in
the following documents executed in connection therewith:

          (i) Note;

          (ii) Deed of Trust; and

                                       2
<PAGE>

          (iii)  Assignment  of Leases  and Rents and other  Income  dated as of
     January 1, 1999, from Grantor, as assignor, to Lender, as assignee.

(The  foregoing  documents,  together  with  any  other  documents  executed  in
connection  with the Loan,  being herein  collectively  referred to as the "Loan
Documents.")  Grantee shall not assume the obligations of Grantor under the Loan
Agreement or the Secured  Environmental  Indemnity,  each dated as of January 1,
1999 (collectively,  the "Restated Agreements"),  between Grantor and Lender, as
such  agreements  are being amended and restated and will be executed by Grantee
directly.  If Lender so  requests,  Grantee  shall  sign a new  promissory  note
containing the same terms and conditions and in the same principal amount of the
Note to further  evidence  Grantee's  liability  for the  payment of the Secured
Indebtedness  and Lender and Grantee shall exchange such new promissory note for
the Note.

     (E) Modification of Loan Documents.

     (i) It is understood  and agreed that,  effective as of the Transfer  Date,
Grantee shall be substituted  for Grantor in each of the Loan Documents and each
of the Loan  Documents  shall be modified to amend the term or terms  defined to
identify  Grantor,  such as "Maker" in the Note,  "Trustor" in the Deed of Trust
and  "Borrower"  in the other Loan  Documents,  so that all such terms  identify
Grantee effective as of the Transfer Date.

     (ii)  Section  1.19 of the Deed of Trust is hereby  amended  by adding  the
following language at the end of such Section 1.19:

          ATrustor shall deliver to  Beneficiary,  within  forty-five  (45) days
          after  the end of each  fiscal  quarter,  income  statements,  balance
          sheets and statements of cash flow of ICG Services, Inc. ("Guarantor")
          and  its  Subsidiaries  (as  defined  in  the  Loan  Agreement),  on a
          consolidated basis, for such quarter, and a certificate of compliance,
          signed by an officer of  Guarantor,  certifying  the  accuracy of such
          statements and Guarantor's  compliance with its obligation to maintain
          at the end of each fiscal  quarter a Tangible Net Worth (as defined in
          the Loan Agreement) of at least fifty million  dollars  ($50,000,000).
          In  addition,   Trustor  shall  deliver  to  Beneficiary  as  soon  as
          practicable,  but in any event no later  than one  hundred  five (105)
          days after each fiscal year,  an income  statement,  balance sheet and
          statement  of  cash  flow of  Guarantor  and  its  Subsidiaries,  on a
          consolidated basis, for such fiscal year, all certified as to accuracy
          by an independent  certified public  accountant or  representative  of
          Guarantor  reasonably  acceptable to  Beneficiary.  All such financial


                                       3
<PAGE>

          statements  shall be prepared in accordance  with  generally  accepted
          accounting principles  consistently applied. Such financial statements
          shall be in form and detail reasonably satisfactory to Beneficiary."

     (iii)  Section  1.21 of the Deed of  Trust  is  hereby  amended  by  adding
"(except  with respect to a transfer  described in Section 5.14  hereof)"  after
"any  interest  in the  Mortgaged  Property"  and  before  ", of if there is any
change. . ."

     (iv) The Deed of Trust is hereby  modified  by adding a new  Section  5.14,

     and Tenant have entered into that certain Agreement  Regarding  Subdivision
     (the  "Subdivision  Agreement"),  whereby the parties  thereto  have agreed
     that, at the request of either  Beneficiary or Tenant, the Property will be
     subdivided,  with the portion of the  Property  currently  improved  with a
     building and parking facilities (the "Improved Parcel") forming one parcel,
     and the  "Expansion  Site"  determined in accordance  with the  Subdivision
     Agreement  forming a second  parcel,  all on the terms and  conditions  set
     forth in the Subdivision  Agreement.  In such case and upon satisfaction of
     all of the conditions set forth in the Subdivision  Agreement,  Beneficiary
     shall  release,  or direct the Trustee to release,  the Expansion Site from
     the lien of this Deed of Trust.  All  expenses of  Beneficiary  and Trustee
     incurred in connection  with  preparing,  negotiation  and  recording  such
     release documents,  and the cost of any endorsement to Beneficiary's  title
     insurance  policy  reasonably  required  by  Beneficiary,  shall be paid by
     Trustor, as set forth in the Subdivision Agreement."

     (F) The  effectiveness of this Agreement and the consents granted by Lender
are conditioned on delivery to Lender of:

          (i) An Amended and Restated  Loan  Agreement,  in form  acceptable  to
     Lender, dated as of May 4, 1999, executed by Grantee;

          (ii) An Unsecured Environmental  Indemnity (the "Indemnity"),  in form
     acceptable  to Lender,  dated as of May 4, 1999,  executed  by Grantor  and
     Grantee; and

          (iii) A Continuing  Guaranty (the  "Guaranty"),  in form acceptable to
     Lender, dated as of May 4, 1999, executed by Grantor.

     (G) Release.  Effective as of the Transfer Date,  Lender  releases  Grantor
from any and all  liability  and  obligation  under the Loan  Documents  and the
Restated Agreements,  and each of them, but not from the documents referenced in
paragraphs (F)(ii) and (iii) of this Agreement.

modification,  extension or renewal of the Secured Indebtedness with the consent
of Grantee  alone,  and  Grantor  hereby  waive  notice of any of the same.  Any
renewal  notes,   modification  or  extension   agreements  or  other  documents
pertaining to the Secured  Indebtedness may hereafter be entered into by Grantee

          (ii) Lender has complied with all terms,  conditions and provisions of
     the Loan Documents to be complied with by Lender, and no event has occurred
     and no  circumstance  exists  that  would,  with the passage of time or the
     giving of notice,  or both,  constitute  a default by Lender under the Loan
     Documents.  There is no existing  basis for Grantor to exercise  any remedy
     available to it by virtue of a default or other action by Lender.

          (iii)  There  are no  charges,  liens,  defenses,  offsets,  claims or
     credits  known or asserted by Grantor  against the  payments  due under the
     Note or other sums due  Lender or  against  the  performance  of  Grantor's
     obligations under the Loan Documents.

          (iv) There are no pending suits, proceedings, judgments, bankruptcies,
     liens or executions  against Grantor or any affiliate of Grantor that could
     adversely affect the Premises.

     necessary  action on the part of  Grantee  and all  required  consents  and
     approvals have been duly obtained.

                                       5
<PAGE>

          (iii) This  Agreement  is a legal,  valid and  binding  obligation  of
     Grantee, enforceable against Grantee in accordance with its terms.

     (K) No  Marshalling  of  Assets.  Lender  may  proceed  against  collateral
securing the Secured  Indebtedness  and against  parties liable therefor in such
order as it may  elect,  and  neither  Grantor  nor  Grantee  nor any  surety or
guarantor for either of them nor any creditor of either Grantor or Grantee shall
be entitled to require Lender to marshall assets. The benefit of any rule of law
or equity to the contrary is hereby expressly waived.

     (L) Impairment of Collateral.  Lender may, in its sole discretion,  release
the Deed of Trust or any other collateral  securing the Secured  Indebtedness or
release any party liable therefor.  The defenses of impairment of collateral and
impairment  of recourse and any  requirement  of  diligence on Lender's  part in
collecting the Secured Indebtedness are hereby waived.

     (M) Amendment and Waiver in Writing.  No provision of this Agreement can be
amended or waived,  except by a  statement  in writing  signed by all parties to
this Agreement.

and those executed  concurrently  herewith  represent the entire agreement among
the parties concerning the Loan.

     (P)  Severability.  Should any  provision  of this  Agreement be invalid or
unenforceable  for any reason,  the remaining  provisions hereof shall remain in
full effect.

     (Q) Applicable Law. The validity and construction of this Agreement and all
other  documents  executed  with  respect to the Secured  Indebtedness  shall be
determined  according to the laws of Colorado  applicable to contracts  executed
and performed within that state.

     (R) Gender and Number.  Words used herein indicating gender or number shall
be read as context may require.

pages,  and it shall not be  necessary  that the  signatures  of all  parties be

Company  representing  50% or more of the combined voting power of the Company's
then outstanding securities;  (b) at any time a majority of the directors of the
Company are persons who were not  nominated  for election by the Board;  (c) the
stockholders  of the Company  approve a merger or  consolidation  of the Company
with any other  corporation,  other than a merger or  consolidation  which would
result in the voting  securities of the Company  outstanding  immediately  prior
thereto  continuing to represent  (either by remaining  outstanding  or by being

combined voting power of the voting  securities of the Company or such surviving
entity  outstanding  immediately  after such  merger or  consolidation;  (d) the
Company shall sell or otherwise  dispose of, in one  transaction  or a series of

options to  purchase  shares of the Company  that have been  granted to Employee

immediately  vest and  Employee  shall be entitled to exercise  such  options in

          (iii)any  requirement  to relocate to another city,  state or country;
               and

          (iv) any material reduction in the value of Employee's  benefits plans
               and programs,  including,  without limiting the generality of the
               foregoing, bonus arrangements.

     5.5  The  Company  may  terminate  this  Agreement  immediately  for  gross
negligence,  intentional  misconduct  or  the  commission  of a  felony  by  the
Employee, in which case all rights under this Agreement shall end as of the date

     5.6  If this Agreement  is  terminated  by the Company  under  Section 4 or
Section 5.3, the Company shall pay Employee a termination fee in an amount equal

under  Section 4 or Employee  terminates  this  Agreement  under  Section 5.3 or
Section  5.4,  all  options to  purchase  shares of the  Company  that have been
granted to Employee  pursuant to the Company's  Stock Option Plans,  but not yet
vested,  will  immediately  vest on the date of termination and Employee will be
entitled to exercise  all options  held by the  Employee for a period of six (6)
months after the date of termination in accordance with the plans and agreements
relating to such options.

Agreement or at any time thereafter disclose any Confidential Information to any
person,  firm or  corporation  to any extent or for any reason or purpose or use
any  Confidential  Information  for any  purpose  other than the  conduct of the
Company's business.

     7.4 Any Confidential Information that is directly or indirectly originated,
developed  or  perfected  to any  degree  by  Employee  during  the  term of his
employment  by the Company  shall be and remain the sole property of the Company

pursuing any other  remedies  for such breach or  threatened  breach,  including
recovery of damages from Employee.

     9. No Waiver.  A waiver by the Company of a breach of any provision of this
Agreement  by  Employee  shall not  operate or be  construed  as a waiver of any
subsequent or other breach by Employee.

     NOW,  THEREFORE,  in  consideration  of the mutual covenants and agreements
contained herein, the parties agree as follows:

agrees to be  employed  on a  full-time  basis by the  Company or by such of its
subsidiary  or  affiliate  corporations  as  determined  by the  Company in such
position as is designated by the Company,  for the period and upon the terms and
conditions hereinafter set forth.

     2.  Duties.  During his  employment,  Employee shall perform the duties and

     3.2 In addition to the base salary, Employee will be eligible for an annual

under  this  Agreement,  upon  presentation  to the  Company by  Employee  of an
itemized accounting of such expenses with reasonable supporting data.

     3.5 The Company  will from time to time provide to Employee  stock  options
pursuant  to and  subject to the terms and  conditions  of the  Company's  Stock
Option Plans.

     4.  Term.  The  initial  term of this  Agreement  will be for two (2) years
commencing  as of the date  hereof  ("Term").  After  one (1) year from the date
hereof,  this Agreement will thereafter  automatically renew from month-to-month
such that there will always be one (1) year  remaining  in the Term,  unless and
until  either  party  shall give at least sixty (60) days notice to the other of
his or its desire to terminate  this Agreement (in such case, the Term shall end
upon the date indicated in such notice).  The applicable  provisions of Sections
6, 7, and 8 shall remain in full force and effect for the time periods specified
in such Sections notwithstanding the termination of this Agreement.

     5.  Termination.

     5.1 If Employee dies during the Term of this Agreement, this Agreement will
terminate.  The Company  will pay the estate of Employee an amount  equal to the
salary for the  remaining  Term of this  Agreement.  In addition,  the estate of

death of Employee in accordance  with the plans and agreements  relating to such
options.

     5.2 If,  during the Term of this  Agreement,  Employee  is  prevented  from
performing  his duties by reason of illness or incapacity  for one hundred forty
(140) days in any one hundred eighty (180) day period, the Company may terminate
this  Agreement,  upon thirty (30) days notice to Employee or his duly appointed
legal  representative.  Employee will be entitled to all benefits provided under
any disability plans of the Company. In addition, Employee or his duly appointed
legal representative will be entitled to exercise all options theretofore vested
under the  Company's  Stock  Option Plans for a period of one (1) year after the
date of termination in accordance with the plans and agreements relating to such
options.

     5.3 For the  purposes  of this  Agreement,  a "Change  in  Control"  of the
Company  shall mean and be deemed to have  occurred if (a) any "person" (as such
term is used in Sections 13(d) and 14(d) of the Securities  Exchange Act of 1934
as amended  (Exchange Act)) is or becomes the "beneficial  owner" (as defined in
Rule 13d-3 under the Exchange Act), directly or indirectly, of securities of the
Company  representing  50% or more of the combined voting power of the Company's
then outstanding securities;  (b) at any time a majority of the directors of the
Company are persons who were not  nominated  for election by the Board;  (c) the


                                       2
<PAGE>

stockholders  of the Company  approve a merger or  consolidation  of the Company
with any other  corporation,  other than a merger or  consolidation  which would
result in the voting  securities of the Company  outstanding  immediately  prior
thereto  continuing to represent  (either by remaining  outstanding  or by being
converted  into voting  securities of the surviving  entity) at least 50% of the
combined voting power of the voting  securities of the Company or such surviving
entity  outstanding  immediately  after such  merger or  consolidation;  (d) the
Company shall sell or otherwise  dispose of, in one  transaction  or a series of
related  transactions,  assets  aggregating  more than 50% of the  assets of the
Company  and  its  subsidiaries  consolidated;  or (e) the  stockholders  of the
Company  approve a plan of complete  liquidation of the Company or any agreement
for the sale or  disposition  by the  Company  of all or  substantially  all the
Company's assets. Upon the occurrence of a Change in Control,  the Company shall
pay Employee an amount equal to one (1) times the aggregate amount of his annual
base salary plus his targeted annual bonus plus the annual value of his benefits
and  perquisites.  At the time of the  occurrence  of a Change  in  Control  all
options to  purchase  shares of the Company  that have been  granted to Employee
pursuant  to the  Company's  Stock  Option  Plans,  but  not  yet  vested,  will
immediately  vest and  Employee  shall be entitled to exercise  such  options in
accordance with the plans and agreements  relating to such options. In addition,
the Company or Employee may terminate  this  Agreement upon at least thirty (30)
days notice at any time within one (1) year after the  occurrence of a Change in
Control of the Company.

     5.4 Employee may terminate  this  Agreement  upon at least thirty (30) days
notice upon the  occurrence  of a  constructive  dismissal of Employee.  For the
purposes  of  this  Agreement,   "constructive  dismissal"  shall  mean,  unless

Company:

          (ii) prior to the  occurrence  of a Change in Control of the  Company,
               any  requirement  to relocate to another city,  state or country,
               provided, however, that this provision shall not be applicable if
               the  principal   executive  offices  of  the  Company  are  being
               relocated to such city, state or country; and

          (iii)any material reduction in the value of Employee's  benefits plans
               and programs,  including,  without limiting the generality of the
               foregoing, bonus arrangements.

     5.5 The  Company  may  terminate  this  Agreement  immediately   for  gross
negligence,  intentional  misconduct  or  the  commission  of a  felony  by  the
Employee, in which case all rights under this Agreement shall end as of the date
of such termination.

     5.6 If this  Agreement  is  terminated  by the Company  under  Section 4 or
Section 5.3, the Company shall pay Employee a termination fee in an amount equal
to two (2) times  the  aggregate  amount  of his  annual  base  salary  plus his
targeted  annual bonus plus the annual  value of his  benefits and  perquisites.
Such  termination  fee will be paid in a lump sum within  fifteen (15) days from
the date of  termination.  If this  Agreement is  terminated  by Employee  under
Section 5.4, the Company  will pay Employee a  termination  fee equal to two (2)


                                       3

times the  aggregate  amount of his annual base salary plus his targeted  annual
bonus plus the annual value of his benefits and  perquisites.  Such  termination
fee  will be paid in a lump  sum  within  fifteen  (15)  days  from  the date of
termination.  In addition,  if Employee  terminates this Agreement under Section
5.3 or Section 5.4, all options to purchase shares of the Company that have been
granted to Employee  pursuant to the Company's  Stock Option Plans,  but not yet
vested,  will  immediately  vest on the date of termination and Employee will be
entitled to exercise  all options  held by the  Employee for a period of six (6)
months after the date of termination in accordance with the plans and agreements
relating to such options.

     6.  Non-Compete and Non-Interference.

     6.1 During the Term of this  Agreement and, if Employee's  employment  with
the Company is terminated under Section 4 or Section 5.3, for a period of twelve
(12) months after such termination,  Employee shall not, directly or indirectly,

affiliates to leave the employ of the Company or any affiliate,  (ii) in any way

reasonable.

                              EMPLOYMENT AGREEMENT

     THIS EMPLOYMENT AGREEMENT ("Agreement") is made as of the 28th day of June,
1999 by and between ICG Communications,  Inc.  ("Employer" or the "Company") and
William S. Beans, Jr. ("Employee").

                                 R E C I T A L S

     WHEREAS, the Company desires to employ Employee as provided herein; and

     WHEREAS, Employee desires to be employed by Employer as provided herein.

     NOW,  THEREFORE,  in  consideration  of the mutual covenants and agreements
contained herein, the parties agree as follows:

     1. Employment.  The Company  agrees to employ  Employee and Employee hereby
agrees to be  employed  on a  full-time  basis by the  Company or by such of its
subsidiary  or  affiliate  corporations  as  determined  by the  Company in such
position as is designated by the Company,  for the period and upon the terms and
conditions hereinafter set forth.

     2. Duties. Employee shall serve as Executive Vice President of the Company.
During  his  employment,   Employee  shall  perform  the  duties  and  bear  the

working time to carrying out his obligations hereunder.

     3.  Compensation and Benefits.

     3.1 The Company  shall pay  Employee  during the Term of this  Agreement an

be Two Hundred and Fifty Thousand Dollars ($250,000.00).

     3.2 In addition to the base salary, Employee will be eligible for an annual
performance  bonus in an exact amount to be determined by the Board of Directors
of the Company or the Compensation Committee of the Board. The annual bonus will
be determined in accordance with the bonus plan of the Company and will be based
on  objectives  and goals set for the Company and  Employee.  Employee's  annual
bonus is  initially  established  at 50% of annual base  salary  (the  "Targeted
Annual  Bonus") if all objectives and goals are met. The annual bonus is payable
at the sole  discretion  of the Company and is contingent  upon  Employee  being
employed  by the  Company as of the date of the  payment  of the  annual  bonus.
Notwithstanding  the  foregoing,  Employee  is  guaranteed  to receive  and will
receive an annual  bonus for 1999 in the amount of One  Hundred  and Twenty Five
Thousand  Dollars  ($125,000);  2/8 of this bonus will be paid to Employee  when


                                       1
<PAGE>

bonuses are paid to all  employees for the second  quarter of 1999,  1/8 of this
bonus will be paid to Employee  when bonuses are paid to all  employees  for the
third  quarter  of 1999  and the  remaining  5/8 of this  bonus  will be paid to
Employee when final bonuses for 1999 are paid to all employees.

     3.3 In addition to salary and bonus payments as provided above, the Company
will provide Employee,  during the Term of this Agreement,  with the benefits of
such insurance plans,  hospitalization  plans and other  perquisites as shall be
generally  provided  to  employees  of the  Company  at his  level and for which
Employee may be eligible under the terms and conditions  thereof.  Employee will
also be entitled to all  benefits  provided  under any  directors  and  officers
liability insurance or errors and omissions insurance maintained by the Company.
Throughout the Term of this Agreement,  the Company will provide Employee with a
car  allowance  in  the  amount  of  One  Thousand  and  Three  Hundred  Dollars
($1,300.00) per month.

     3.4 Throughout  the Term of  this  Agreement,  the Company  will  reimburse
Employee  for all  reasonable  out-of-pocket  expenses  incurred  by Employee in
connection  with the business of the Company and the  performance  of his duties
under  this  Agreement,  upon  presentation  to the  Company by  Employee  of an
itemized accounting of such expenses with reasonable supporting data.

     3.5 The Company may from time to time  provide to  Employee  stock  options
pursuant  to and  subject to the terms and  conditions  of the  Company's  stock

vesting in equal  increments  over three years  (subject to the approval of such
grant by the Stock Option  Committee of the Board of Directors of the  Company);
(2) 135,186  non-qualified  stock  options  with an exercise  price equal to the

equal  increments  over three years;  and (3) 260,000  Share Price  Appreciation
Vesting  non-qualified stock options with an exercise price equal to the closing
stock price of the  Company's  common stock on June 28, 1999 vesting  based upon
share price  appreciation,  in each case pursuant to the terms of a stock option
agreement to be entered into between Employee and the Company.

     3.6 The Company will pay Employee certain  relocation  expenses  associated
with Employee's relocation from New Jersey to the Denver,  Colorado metropolitan
area. This  reimbursement  will be pursuant to the Tier One Relocation Policy of
the Company.

     3.7 Employee  will be entitled to a  moving  allowance  of $50,000 to cover

by paying  additional  amounts  under this  Section 3.7 so that the total amount
paid under this  Section 3.7 ("X")  equals the $50,000  amount  reimbursable  to

or (b) as a deduction to any lump-sum payment made to Employee by the Company in
connection with a termination of his employment hereunder.

     4.  Term.  The  initial  term of this  Agreement  will be for two (2) years
commencing  as of the date  hereof  ("Term").  After  one (1) year from the date
hereof,  this Agreement will thereafter  automatically renew from month-to-month
such that there will always be one (1) year  remaining  in the Term,  unless and
until  either  party  shall give at least sixty (60) days notice to the other of
his or its desire to terminate  this Agreement (in such case, the Term shall end
upon the date indicated in such notice).  The applicable  provisions of Sections
6, 7, and 8 shall remain in full force and effect for the time periods specified
in such Sections notwithstanding the termination of this Agreement.

     5.  Termination.

for a period of one (1) year after the date of death of Employee  in  accordance
with the plans and agreements relating to such options.

     5.2 If,  during the Term of this  Agreement,  Employee  is  prevented  from
performing  his duties by reason of illness or incapacity  for one hundred forty
(140) days in any one hundred eighty (180) day period, the Company may terminate
this  Agreement,  upon thirty (30) days notice to Employee or his duly appointed

<PAGE>

under the Stock Option Agreements for a period of one (1) year after the date of
termination  in  accordance  with the  plans  and  agreements  relating  to such
options.

     5.3 For the  purposes  of this  Agreement,  a "Change  in  Control"  of the
Company  shall mean and be deemed to have  occurred if (a) any "person" (as such
term is used in Sections 13(d) and 14(d) of the Securities  Exchange Act of 1934
as amended  (Exchange Act)) is or becomes the "beneficial  owner" (as defined in
Rule 13d-3 under the Exchange Act), directly or indirectly, of securities of the
Company  representing  50% or more of the combined voting power of the Company's
then outstanding securities;  (b) at any time a majority of the directors of the
Company are persons who were not  nominated  for election by the Board;  (c) the
stockholders  of the Company  approve a merger or  consolidation  of the Company
with any other  corporation,  other than a merger or  consolidation  which would
result in the voting  securities of the Company  outstanding  immediately  prior
thereto  continuing to represent  (either by remaining  outstanding  or by being
converted  into voting  securities of the surviving  entity) at least 50% of the
combined voting power of the voting  securities of the Company or such surviving
entity  outstanding  immediately  after such  merger or  consolidation;  (d) the
Company shall sell or otherwise  dispose of, in one  transaction  or a series of
related  transactions,  assets  aggregating  more than 50% of the  assets of the
Company  and  its  subsidiaries  consolidated;  or (e) the  stockholders  of the
Company  approve a plan of complete  liquidation of the Company or any agreement
for the sale or  disposition  by the  Company  of all or  substantially  all the
Company's assets. Upon the occurrence of a Change in Control,  the Company shall
pay Employee an amount equal to one (1) times the aggregate amount of his annual
base salary plus his Targeted Annual Bonus plus the annual value of his benefits
and  perquisites.  At the time of the  occurrence  of a Change  in  Control  all
options to  purchase  shares of the Company  that have been  granted to Employee
pursuant to the Stock Option Agreements or the Company's stock option plans, but
not yet vested, will immediately vest and Employee shall be entitled to exercise
such  options  in  accordance  with the plans and  agreements  relating  to such
options,  provided,  however,  that the  options  granted  under the Share Price
Appreciation Vesting Non-Qualified Option Agreement,  dated as of June 28, 1999,
between  Employee  and the  Company  shall not vest on an  accelerated  basis as
provided  herein upon the  occurrence of a Change in Control.  In addition,  the

Company:

          (i)  any reduction in the annual salary of Employee;

          (ii) prior to the  occurrence  of a Change in Control of the  Company,
               any   requirement  to  relocate  to  another  state  or  country,
               provided, however, that this provision shall not be applicable if
               the  principal   executive  offices  of  the  Company  are  being


                                       4
<PAGE>

               relocated to such state or country; and

          (iii)any material reduction in the value of Employee's  benefits plans
               and programs.

     5.5  The  Company  may  terminate  this  Agreement  immediately  for  gross
negligence, intentional misconduct or the commission of a felony by Employee, in
which case all  rights  under  this  Agreement  shall end as of the date of such
termination.

     5.6 If this  Agreement is  terminated  by the Company  under Section 4, the
Company shall pay Employee a termination fee in an amount equal to the aggregate
amount of his annual base salary that would have been paid during the  remaining
Term of the  Agreement.  If this  Agreement is  terminated  by the Company under
Section 5.3, the Company shall pay Employee a termination fee in an amount equal
to two (2) times  the  aggregate  amount  of his  annual  base  salary  plus his
Targeted  Annual Bonus plus the annual  value of his  benefits and  perquisites.
Such  termination  fee will be paid in a lump sum within  fifteen (15) days from
the date of  termination.  If this  Agreement is  terminated  by Employee  under
Section 5.4, the Company  will pay Employee a  termination  fee equal to two (2)
times the  aggregate  amount of his annual base salary plus his Targeted  Annual
Bonus plus the annual value of his benefits and  perquisites.  Such  termination
fee  will be paid in a lump  sum  within  fifteen  (15)  days  from  the date of
termination.  In addition,  if Employee  terminates this Agreement under Section
5.3 or Section 5.4, all options to purchase shares of the Company that have been
granted to Employee  pursuant to the Stock Option  Agreements  or the  Company's
stock option plans,  but not yet vested,  will  immediately  vest on the date of
termination  and  Employee  will be  entitled to  exercise  all options  held by
Employee  for a  period  of six (6)  months  after  the date of  termination  in
accordance  with the plans and  agreements  relating to such options,  provided,
however,  that the options  granted under the Share Price  Appreciation  Vesting
Non-Qualified Option Agreement,  dated as of June 28, 1999, between Employee and
the Company shall not vest on an accelerated  basis as provided  herein upon the
occurrence of a Change in Control.

     6.  Non-Compete and Non-Interference.

     6.1 During the Term of this  Agreement and, if Employee's  employment  with
the Company is terminated under Section 4 or Section 5.3, for a period of twelve
(12) months after such termination,  Employee shall not, directly or indirectly,
own, manage, operate,  control, be employed by, or participate in the ownership,
management,  operation  or control  of, a  business  that is engaged in the same

Employee's  employment or at the time  Employee's  employment is  terminated,  a
Relevant  Area.  A "Relevant  Area"  shall be defined  for the  purposes of this
Agreement as any area located  within,  or within fifty (50) miles of, the legal
boundaries or limits of any city within which the Company is engaged in business
or in which the  Company  has  publicly  announced  or  privately  disclosed  to
Employee that it plans to engage in business.

                        SHARE PRICE APPRECIATION VESTING
                      NON-QUALIFIED STOCK OPTION AGREEMENT

     AGREEMENT   made  as  of  this  28th  day  of  June,   1999   between   ICG
Communications,  Inc., a Delaware  corporation (the  "Company"),  and William S.
Beans, Jr. (the "Employee").

                               W I T N E S E T H:

     WHEREAS,  the Company  desires,  in connection  with the  employment of the
Employee,  to provide the Employee with an  opportunity to acquire common stock,
$.01 par value  (hereinafter  referred to as "Common Stock"),  of the Company on
favorable terms and thereby  increase his proprietary  interest in the continued
progress and success of the business of the Company;

     NOW,  THEREFORE,  in  consideration  of the premises,  the mutual covenants
herein set forth and other good and valuable consideration,  the Company and the
Employee hereby agree as follows:

     1.  Confirmation  of Grant of Option.  Pursuant to a  determination  by the
Stock  Option  Committee  of the Board of  Directors  of the Company (the "Stock
Option  Committee"),  made on June 28, 1999 (the "Date of Grant"),  the Company,
subject to the terms of this  Agreement,  hereby  confirms that the Employee has
been granted as a matter of separate  inducement and agreement,  and in addition
to and not in lieu of salary or other  compensation  for services,  the right to
purchase  (hereinafter  referred to as the  "Option")  an  aggregate  of 260,000
shares of Common  Stock,  subject to  adjustment as provided in Section 8 hereof
(such shares, as adjusted, shall hereinafter be referred to as the "Shares").

     2. Purchase Price.  The purchase price of shares of Common Stock covered by
the Option will be $20.25 per share (the "Exercise Price") subject to adjustment
as provided in Section 8 hereof.

     3. Exercise of Option.  The Option shall vest and become exercisable on the
terms and conditions hereinafter set forth:

          A.  The  Option  shall  become  exercisable  cumulatively  as  to  the
     following amounts of the number of Shares originally subject thereto (after
     giving effect to any adjustment pursuant to Section 8 hereof), on the dates
     and subject to the terms and conditions indicated:

               1. Upon the six month  anniversary of the date of this Agreement,
          a number of Shares,  if any,  equal to 50% of the Earned  Shares Value
          (as defined  herein) shall vest to the Employee.  For purposes of this
          subparagraph,  "Earned  Shares  Value" shall be determined as follows:
          (i)  Subtract  the Base Price (as defined in  subparagraph  (C) below)
          from the applicable  Anniversary Price (as defined in subparagraph (B)
          below),  and then round such result down to the nearest  whole  number
          divisible by five (the "Increase Amount"),  and (ii) locate on Exhibit
<PAGE>

          "B" hereto the  corresponding  Earned  Shares Value for such  Increase
          Amount.  If the  Increase  Amount is less  than or equal to five,  the
          Earned  Shares  Value shall equal zero and no Shares will vest on such
          anniversary date.

               2. Upon every  succeeding  six month  anniversary  of the date of
          this Agreement until, but not including,  the fifth anniversary of the
          date of this Agreement, an incremental number of Shares subject to the
          Option shall vest to the Employee equal to the excess,  if any, of (a)
          50% of the  Earned  Shares  Value (as  defined  herein),  over (b) the
          aggregate  number of Shares  subject  to the Option  which  previously
          vested  under  this  Agreement.  For  purposes  of this  subparagraph,
          "Earned Shares Value" shall be determined by rounding the  Anniversary
          Price (as defined in subparagraph (B) below) down to the nearest whole
          number  divisible  by five (the  "Increase  Amount")  and locating the
          corresponding  Earned  Shares  Value  on  Exhibit  B  hereto  for such
          Increase Amount. If the Increase Amount is less than or equal to five,
          the Earned  Shares  Value  shall equal zero and no Shares will vest on
          such anniversary date.

               3. Upon the fifth anniversary of the date of this Agreement,  all
          of the remaining Shares subject to the Option but not yet vested shall
          vest to the Employee.

          B. The  "Anniversary  Price" shall mean the average  closing price per
     share of the Common Stock for the five trading  days  immediately  prior to
     the day as to which the Anniversary Price is being determined on the NASDAQ
     National Market or national stock exchange,  as the case may be, or, if the
     Common Stock is not included on the NASDAQ  National  Market or listed on a
     national  stock  exchange,  the average  closing  sales price of the Common
     Stock as reported for such five trading days on the NASDAQ  SmallCap Market
     or, if the Common  Stock shall not be so  included,  the average of the bid
     and asked  prices at the end of the day in the  over-the-counter  market as
     reported by NASDAQ for the five trading days  immediately  prior to the day
     on which the Anniversary  Price is being determined or, if the Common Stock
     is not included on NASDAQ,  as reported by the National  Quotation  Bureau,
     Inc. or any successor organization.

          C. The "Base Price"  shall mean the closing  price of the Common Stock
     as  reported  on the NASDAQ  National  Market on June 28,  1999,  which the
     parties agree was $20.25.

          D. The Option may be  exercised  pursuant  to the  provisions  of this
     Section 3, by notice and payment (including, but not limited to, a cashless
     exercise) to the Company as provided in Sections 11 and 16 hereof.

     4. Term of  Option.  The term of the  Option  shall be a period of ten (10)
years from the Date of Grant,  subject to earlier termination or cancellation as
provided in this Agreement. The Option, to the extent unexercised,  shall expire
on the day immediately  prior to the tenth anniversary of the Date of Grant. The
holder of the Option  shall not have any rights to dividends or any other rights
of a  stockholder  with  respect  to any shares of Common  Stock  subject to the
Option  until such  shares  shall have been issued to him (as  evidenced  by the


                                       2
<PAGE>

appropriate  entry  on the  books  of a duly  authorized  transfer  agent of the
Company)  provided that the date of issuance  shall not be earlier than the date
the Option is exercised  and  provision  of the purchase  price of the shares of
Common Stock (with  respect to which the Option is being  exercised)  is made to
the Company pursuant to the provisions contained herein.

     5.  Non-transferability  of Option.  The Option  shall not be  transferable
otherwise than by will or by the laws of descent and distribution or pursuant to
a domestic  relations order, and the Option may be exercised during the lifetime
of the  Employee  only by him.  More  particularly,  but  without  limiting  the
generality of the foregoing, the Option may not be assigned, transferred (except
as provided in the immediately  preceding sentence) or otherwise disposed of, or
pledged or  hypothecated  in any way,  and shall not be  subject  to  execution,
attachment or other process. Any assignment,  transfer, pledge, hypothecation or
other  disposition  of the Option  attempted  contrary to the provisions of this
Agreement, or any levy of execution,  attachment or other process attempted upon
the Option,  will be null and void and without  effect.  Any attempt to make any
such assignment,  transfer,  pledge,  hypothecation or other  disposition of the
Option or any attempt to make any such levy of  execution,  attachment  or other
process will cause the Option to terminate immediately upon the happening of any
such event; provided, however, that any such termination of the Option under the
foregoing provisions of this Section 5 will not prejudice any rights or remedies
which the Company or any Parent or Subsidiary  may have under this  Agreement or
otherwise.

     6. Exercise Upon Cessation of  Employment.  (a) If the Employee at any time
ceases to be an employee of the  Company  and of any parent  corporation  of the
Company (a  "Parent")  within the  meaning  of  Section  424(e) of the  Internal
Revenue Code of 1986, as amended (the "Code"), or subsidiary  corporation of the
Company (a  "Subsidiary")  within the  meaning of Section  424(f) of the Code by
reason of his discharge for Good Cause (as defined below),  the Option shall, at
the time of such  termination  of  employment,  terminate and the Employee shall
forfeit all rights  hereunder.  If,  however,  the Employee for any other reason
(other than Disability or death) ceases to be such an employee,  the Option may,
subject to the  provisions  of  Sections  5 and 8 hereof,  be  exercised  by the
Employee to the same extent the Employee  would have been entitled under Section
3  hereof  to  exercise  the  Option  immediately  prior  to such  cessation  of
employment,  at any time  within  three  (3)  months  after  such  cessation  of
employment,  at the end of which  period  the  Option,  to the  extent  not then
exercised,  shall terminate and the Employee shall forfeit all rights hereunder,
even if the  Employee  subsequently  returns to the employ of the Company or any
Parent or Subsidiary.  In no event,  however,  may the Option be exercised after
the expiration of the term provided in Section 4 hereof.

     As used herein, "Good Cause" shall mean (i) the Employee's willful or gross
misconduct or willful or gross  negligence in the  performance of his duties for
the Company or for any Parent or Subsidiary  after prior written  notice of such
misconduct or  negligence  and the  continuance  thereof for a period of 30 days
after receipt by the Employee of such notice, (ii) the Employee's intentional or
habitual  neglect of his duties for the Company or for any Parent or  Subsidiary
after prior written  notice of such neglect,  or (iii) the  Employee's  theft or
misappropriation  of funds of the  Company  or of any  Parent or  Subsidiary  or
commission of a felony.


                                       3
<PAGE>

     (b) The Option shall not be affected by any change of duties or position of
the  Employee so long as he continues to be an employee of the Company or of any
Parent or Subsidiary thereof who is regularly employed on a salaried basis.

     7. Exercise Upon Death or Disability.  (a) If the Employee dies while he is
employed  by the  Company or by any Parent or  Subsidiary  (or within  three (3)
months after his Retirement (as defined  below),  and on or after the first date
upon  which he would  have  been  entitled  to  exercise  the  Option  under the
provisions  of Section 3 hereof,  the Option may,  subject to the  provisions of
Sections 5 and 8 hereof,  be  exercised  with  respect to all or any part of the
shares of Common Stock as to which the deceased  Employee had not  exercised the
Option  at the  time  of his  death  (but  only to the  extent  the  Option  was
exercisable at the earlier of (i) the date of his Retirement or (ii) the date of
his  death),  by the estate of the  Employee  (or by the  person or persons  who
acquire the right to exercise the Option by written designation of the Employee)
at any  time  within  the  period  ending  one (1)  year  after  the date of the
Employee's  death  (in no  event,  however,  after  the  expiration  of the term
provided in Section 4 hereof),  at the end of which  period the  Option,  to the
extent not then exercised, shall terminate and the estate or other beneficiaries
shall forfeit all rights hereunder.

     As used herein,  "Retirement"  shall mean the  termination of employment by
the Employee from the Company or from any Parent or Subsidiary,  who at the time
of  such  termination  is at  least  fifty-five  (55)  years  of age and who has
completed at least ten (10) years of service (at least 1,000 hours in any fiscal
year) with the Company or any Parent or Subsidiary, or any combination thereof.

     (b) In the event that the employment of the Employee by the Company and any
Parent or  Subsidiary  is  terminated  by reason of the  Disability  (as defined
below) of the  Employee on or after the first date upon which he would have been
entitled to exercise the Option under the  provisions  of Section 3 hereof,  the
Option may,  subject to the provisions of Sections 5 and 8 hereof,  be exercised
with respect to all or any part of the shares of Common Stock as to which he had
not exercised the Option at the time of his  Disability  (but only to the extent
the Option was exercisable at such time) by the Employee, at any time within the
period ending one (1) year after the date of such  termination of employment (in
no event,  however,  after the  expiration  of the term  provided  in  Section 4
hereof),  at the  end of  which  period  the  Option,  to the  extent  not  then
exercised,  shall terminate and the Employee shall forfeit all rights  hereunder
even if the  Employee  subsequently  returns to the employ of the Company or any
Parent or Subsidiary.  As used herein,  "Disability" shall have the same meaning
as the term "permanent and total disability" under Section 22(e)(3) of the Code.

     8. Adjustments. In the event there is any change in the Common Stock of the
Company by reason of any  reorganization,  recapitalization,  stock split, stock
dividend or otherwise,  there shall be substituted for or added to each share of
Common Stock theretofore appropriated or thereafter subject, or which may become
subject,  to this  Option  the  number  and  kind of  shares  of  stock or other
securities into which each outstanding share of Common Stock shall be so changed
or for which each such share shall be exchanged,  or to which each such share be
entitled,  as the case may be,  and the per share  price  thereof  also shall be
appropriately adjusted.


                                       4

     9. Merger,  Consolidation  or Change in Control of the Company.  Subject to
the provisions of Section 8 hereof,  upon (a) the merger or consolidation of the
Company with or into another corporation  (pursuant to which the stockholders of
the Company  immediately  prior to such merger or consolidation  will not, as of
the date of such merger or consolidation, own a beneficial interest in shares of
voting  securities of the  corporation  surviving  such merger or  consolidation
having at least a majority of the combined  voting  power of such  corporation's
then outstanding  securities),  if the agreement of merger or consolidation does
not provide for (i) the  continuance of this Option or (ii) the  substitution of
new  option(s)  for this  Option,  or for the  assumption  of such Option by the
surviving corporation, (b) the dissolution, liquidation or sale of substantially
all the assets of the Company or (c) a Change in Control  (as defined  below) of
the  Company,  any options  which remain  unvested  shall be forfeited as of the
effective time of any merger, consolidation,  dissolution,  liquidation, sale of
assets or Change in Control of the Company.

     As used  herein,  a "Change in Control of the  Company"  shall be deemed to
have occurred if any person  (including  any  individual,  firm,  partnership or
other entity) together with all Affiliates and Associates (as defined under Rule
12b-2 of the General  Rules and  Regulations  promulgated  under the  Securities
Exchange Act of 1934, as amended, and the rules and regulations  thereunder (the
"Exchange Act")) of such person,  but excluding (i) a trustee or other fiduciary
holding  securities  under  an  employee  benefit  plan  of the  Company  or any
subsidiary of the Company, (ii) a corporation owned, directly or indirectly,  by
the stockholders of the Company in  substantially  the same proportions as their
ownership of the Company,  (iii) the Company or any subsidiary of the Company or
(iv) only as  provided  in the  immediately  following  sentence,  the  Employee
together with all Affiliates  and Associates of the Employee,  is or becomes the
Beneficial Owner (as defined in Rule 13d-3  promulgated under the Exchange Act),
directly or indirectly, of securities of the Company representing 40% of more of
the combined  voting power of the Company's then  outstanding  securities,  such
person being hereinafter  referred to as an Acquiring Person.  The provisions of
clause (iv) of the immediately  preceding sentence shall apply only with respect
to the  Option(s)  held by the  Employee if,  together  with his  Affiliates  or
Associates,  if any, he is or becomes the direct or indirect Beneficial Owner of
the percentage of securities set forth in such clause.

     10.  Registration.  The shares of Common Stock subject  hereto and issuable
upon the exercise hereof may not be registered under the Securities Act of 1933,
as amended,  and, if required  upon the request of counsel to the  Company,  the
Employee will give a representation  as to his investment intent with respect to
such shares prior to their issuance as set forth in Section 11 hereof.

     The  Company may  register or qualify the shares  covered by the Option for
sale  pursuant to the  Securities  Act of 1933,  as  amended,  and the rules and
regulations  thereunder (the "Securities Act") at any time prior to or after the
exercise in whole or in part of the Option.

     11. Method of Exercise of Option.  (a) Subject to the terms and  conditions
of this  Agreement,  the Option shall be exercisable by notice in the manner set
forth in  Exhibit A hereto  (the  "Notice")  and  provision  for  payment to the


                                       5
<PAGE>

Company in accordance  with the procedure  prescribed  herein.  Each such Notice
shall:

               (i) state the  election to exercise  the Option and the number of
          Shares in respect of which it is being exercised;

               (ii) contain a  representation  and  agreement  as to  investment
          intent,  if required by counsel to the  Company  with  respect to such
          Shares, in form satisfactory to counsel for the Company;

               (iii) be signed by the Employee or the person or persons entitled
          to exercise  the Option and, if the Option is being  exercised  by any
          person or persons other than the Employee,  be  accompanied  by proof,
          satisfactory  to counsel for the Company,  of the right of such person
          or persons to exercise the Option; and

               (iv) be  received  by the  Company  on or before  the date of the
          expiration of this Option. In the event the date of expiration of this
          Option  falls on a day  which  is not a  regular  business  day at the
          Company's executive offices in Englewood,  Colorado, then such written
          notice must be  received at such office on or before the last  regular
          business day prior to such date of expiration.

     (b) Payment of the purchase price of any shares of Common Stock, in respect
of which the Option  shall be  exercised,  shall be made by the Employee or such
person or persons at the place  specified  by the Company at the time the Notice
is delivered to the Company (i) by delivering to the Company a certified or bank
cashier's  check payable to the order of the Company,  (ii) by delivering to the
Company   properly   endorsed   certificates  of  shares  of  Common  Stock  (or
certificates   accompanied  by  an  appropriate   stock  power)  with  signature
guaranties by a bank or trust company,  (iii) by having  withheld from the total
number of shares of Common Stock to be acquired upon the exercise of this Option
a  specified  number  of such  shares  of  Common  Stock,  (iv)  by any  form of
"cashless" exercise or (v) by any combination of the above.

     (c) The Option shall be deemed to have been  exercised  with respect to any
particular  shares of Common Stock if, and only if, the preceding  provisions of
this Section 11 and the provisions of Section 12 hereof shall have been complied
with,  in which event the Option  shall be deemed to have been  exercised on the
date the Notice of exercise of the Option was received by the Company.  Anything
in this Agreement to the contrary notwithstanding,  any notice of exercise given
pursuant to the  provisions of this Section 11 shall be void and of no effect if
all the preceding provisions of this Section 11 and the provisions of Section 12
shall not have been complied with.

     (d) The certificate or certificates  for shares of Common Stock as to which
the Option shall be exercised will be registered in the name of the Employee (or
in the name of the  Employee's  estate  or other  beneficiary  if the  Option is
exercised  after the  Employee's  death),  or if the Option is  exercised by the
Employee  and if the Employee so requests in the notice  exercising  the Option,
will be registered in the name of the Employee and another person jointly,  with
right of survivorship  and will be delivered as soon as practical after the date
the  Notice  (and  full  payment)  is  received  by the  Company,  but only upon
compliance with all of the provisions of this Agreement.


                                       6
<PAGE>

     (e) If the Employee fails to accept delivery of and pay for all or any part
of the  number  of Shares  specified  in such  Notice  upon  tender or  delivery
thereof,  his right to  exercise  the Option  with  respect to such  undelivered
Shares may be terminated in the sole discretion of the Board of Directors of the
Company. The Option may be exercised only with respect to full Shares.

     (f) The Company  shall not be required to issue or deliver any  certificate
or  certificates  for shares of its Common Stock  purchased upon the exercise of
any part of this Option prior to the payment to the Company, upon its demand, of
any amount requested by the Company for the purpose of satisfying its liability,
if any,  to  withhold  state  or  local  income  or  earnings  tax or any  other
applicable tax or assessment (plus interest or penalties thereon, if any, caused
by a delay in making such  payment)  incurred by reason of the  exercise of this
Option or the transfer of shares  thereupon.  Such payment  shall be made by the
Employee  in cash or,  with the  consent of the  Company,  by  tendering  to the
Company  shares of Common  Stock  equal in value to the  amount of the  required
withholding.  In the alternative,  the Company may, at its option,  satisfy such
withholding  requirements  by withholding  from the shares of Common Stock to be
delivered  to the  Employee  pursuant  to an exercise of this Option a number of
shares of Common Stock equal in value to the amount of the required withholding.

     12.  Approval of Counsel.  The  exercise of the Option and the issuance and
delivery of shares of Common Stock pursuant thereto shall be subject to approval
by the Company's counsel of all legal matters in connection therewith, including
compliance with the  requirements of the Securities Act and the Exchange Act and
the  requirements  of any stock exchange upon which the Common Stock may then be
listed.

     13.  Resale of Common Stock.  (a) If so requested by the Company,  upon any
sale or transfer of the Common Stock purchased upon exercise of the Option,  the
Employee shall deliver to the Company an opinion of counsel  satisfactory to the
Company to the effect that either (i) the Common Stock to be sold or transferred
has been  registered  under  the  Securities  Act and that  there is in effect a
current  prospectus  meeting the requirements of Section 10(a) of the Securities
Act which is being or will be delivered to the  purchaser  or  transferee  at or
prior to the time of delivery of the certificates evidencing the Common Stock to
be sold or  transferred,  or (ii) such  Common  Stock  may then be sold  without
violating Section 5 of the Securities Act.

     (b) The Common  Stock  issued upon  exercise  of the Option  shall bear the
following legend if required by counsel for the Company:

                  THE  SHARES  EVIDENCED  BY THIS  CERTIFICATE  MAY NOT BE SOLD,
                  TRANSFERRED,  PLEDGED,  HYPOTHECATED OR OTHERWISE  DISPOSED OF
                  UNLESS THEY HAVE FIRST BEEN  REGISTERED  UNDER THE  SECURITIES
                  ACT OF 1933, AS AMENDED,  OR UNLESS, IN THE OPINION OF COUNSEL
                  FOR THE COMPANY, SUCH REGISTRATION IS NOT REQUIRED.


                                       7
<PAGE>

     14.  Reservation  of Shares.  To the extent  shares of Common Stock are not
readily tradable over an established securities market, the Company shall at all
times during the term of the Option  reserve and keep  available  such number of
shares of the class of stock then subject to the Option as will be sufficient to
satisfy the requirements of this Agreement.

     15.  Limitation of Action.  The Employee and the Company each  acknowledges
that  every  right of  action  accruing  to him or it,  as the case may be,  and
arising out of or in  connection  with this  Agreement  against the Company or a
Parent or  Subsidiary,  on the one hand, or against the  Employee,  on the other
hand, shall, irrespective of the place where an action may be brought, cease and
be barred by the  expiration of three years from the date of the act or omission

     5.3 For the  purposes  of this  Agreement,  a "Change  in  Control"  of the
Company  shall mean and be deemed to have  occurred if (a) any "person" (as such

as amended  (Exchange Act)) is or becomes the "beneficial  owner" (as defined in
Rule 13d-3 under the Exchange Act), directly or indirectly, of securities of the
Company  representing  50% or more of the combined voting power of the Company's
then outstanding securities;  (b) at any time a majority of the directors of the
Company are persons who were not  nominated  for election by the Board;  (c) the
stockholders  of the Company  approve a merger or  consolidation  of the Company
with any other  corporation,  other than a merger or  consolidation  which would
result in the voting  securities of the Company  outstanding  immediately  prior
thereto  continuing to represent  (either by remaining  outstanding  or by being
converted  into voting  securities of the surviving  entity) at least 50% of the
combined voting power of the voting  securities of the Company or such surviving
entity  outstanding  immediately  after such  merger or  consolidation;  (d) the
Company shall sell or otherwise  dispose of, in one  transaction  or a series of
related  transactions,  assets  aggregating  more than 50% of the  assets of the
Company  and  its  subsidiaries  consolidated;  or (e) the  stockholders  of the


                                       2
<PAGE>

Company  approve a plan of complete  liquidation of the Company or any agreement
for the sale or  disposition  by the  Company  of all or  substantially  all the
Company's assets. Upon the occurrence of a Change in Control,  the Company shall
pay Employee an amount equal to one (1) times the aggregate amount of his annual
base salary plus his targeted annual bonus plus the annual value of his benefits
and  perquisites.  At the time of the  occurrence  of a Change  in  Control  all
options to  purchase  shares of the Company  that have been  granted to Employee
pursuant  to the  Company's  Stock  Option  Plans,  but  not  yet  vested,  will
immediately  vest and  Employee  shall be entitled to exercise  such  options in
accordance with the plans and agreements  relating to such options. In addition,
the Company or Employee may terminate  this  Agreement upon at least thirty (30)
days notice at any time within one (1) year after the  occurrence of a Change in
Control of the Company.

     5.4 Employee may terminate  this  Agreement  upon at least thirty (30) days
notice upon the  occurrence  of a  constructive  dismissal of Employee.  For the
purposes  of  this  Agreement,   "constructive  dismissal"  shall  mean,  unless
consented  to by  Employee  in  writing,  any of the  following  actions  by the
Company:

     (i)  any reduction in the annual salary or bonus level of Employee;

     (ii) any  requirement to relocate,  except for office  locations that would
          not  increase the  Employee's  one-way  commute  distance by more than
          twenty (20) miles;

     (iii)any material  reduction in the value of Employee's  benefits plans and
          programs; and

     (iv) any  reduction  or  material  change  in  title,  positions,   duties,
          responsibilities, powers and reporting structure.

     5.5 The Company may terminate  this Agreement  immediately  for willful and
intentional  gross  negligence,  misconduct or the conviction of a felony by the
Employee, in which case all rights under this Agreement shall end as of the date
of such  termination.  No act, shall be considered  "willful"  unless  committed
without good faith and a  reasonable  belief that the act or omission was in the
Company's best interest.

     5.6 If this  Agreement is  terminated  by the Company  under Section 4, the
Company shall pay Employee a termination fee in an amount equal to the aggregate
amount of his annual base salary that would have been paid during the  remaining
Term of the  Agreement  plus his targeted  annual bonus plus the annual value of
his benefits and  perquisites.  If this  Agreement is  terminated by the Company
under Section 5.3, or, for the avoidance of doubt, under Section 4 within twelve
(12)  months of a "change of  control"  as defined in Section  5.3,  the Company
shall pay  Employee a  termination  fee in an amount  equal to two (2) times the
aggregate  amount of his annual base salary plus his targeted  annual bonus plus
the annual value of his benefits and  perquisites.  Such termination fee will be
paid in a lump sum within  fifteen  (15) days from the date of  termination.  If
this Agreement is terminated by Employee under Section 5.4, the Company will pay
Employee a termination  fee equal to two (2) times the  aggregate  amount of his
annual base salary plus his  targeted  annual bonus plus the annual value of his
benefits and perquisites. Such termination fee will be paid in a lump sum within
fifteen  (15)  days  from the date of  termination.  In  addition,  if  Employee
terminates this Agreement under Section 5.3 or Section 5.4 or Company terminates
this Agreement  under Section 4 or Section 5.3 all options to purchase shares of
the Company that have been granted to Employee  pursuant to the Company's  Stock
Option  Plans,  but  not  yet  vested,  will  immediately  vest  on the  date of
termination  and  Employee  will be entitled to exercise all options held by the


                                       3
<PAGE>

Employee  for a period of twelve (12) months  after the date of  termination  in
accordance with the plans and agreements relating to such options.

     5.7. If Employee  remains an employee  of the Company  until  February  17,
2000, then Employee will have the right to voluntarily  terminate his employment
with the Company  anytime  thereafter  and  receive six months  salary and fifty
percent (50%) of his annual bonus and six (6) months health insurance benefits.

     5.8. The parties  acknowledge  that all stock  options  granted to Employee
under the Netcom  On-Line  Communication  Services,  Inc. 1993 Stock Option Plan
(Amended and Restated as of January 23,  1997) have been vested.  If  Employee's
employment terminates for any reason, including Employee's resignation, Employee
will be entitled to exercise all such options for a period of one (1) year after
the date of termination in accordance with the plans and agreements  relating to
such options.

     6. Non-Compete and Non-Interference.

     6.1 During the Term of this  Agreement and, if Employee's  employment  with
the Company is terminated under Section 4 or Section 5.3, for a period of twelve
(12) months after such termination,  Employee shall not, directly or indirectly,
own, manage,  operate,  control, be employed by, or participate in the ownership
(more than 5%), management,  operation or control of, a business that is engaged
materially  in the same  business as the Company  within any area  constituting,
during the term of Employee's employment or at the time Employee's employment is
terminated, a Relevant Area. A "Relevant Area" shall be defined for the purposes
of this Agreement as any area located within, or within fifty (50) miles of, the
legal  boundaries  or limits of any city within  which the Company is engaged in
business or in which the Company has publicly  announced or privately  disclosed
to Employee that it plans to engage in business.

     6.2.  During the Term of this  Agreement  and for a period of two (2) years
after  termination  of  this  Agreement,  Employee  shall  not (i)  directly  or
indirectly  cause or attempt to cause any  employee of the Company or any of its
affiliates to leave the employ of the Company or any affiliate,  (ii) in any way
interfere with the relationship  between the Company and any employee or between
an affiliate and any employee of the affiliate, or (iii) interfere or attempt to
interfere with any transaction in which the Company or any of its affiliates was
involved during the Term of this Agreement.

     6.3 Employee  agrees  that,  because of the nature and  sensitivity  of the
information to which he will be privy and because of the nature and scope of the
Company's  business,  the restrictions  contained in this Section 6 are fair and
reasonable.


     7. Confidential Information.

     7.1 The relationship  between the Company and Employee is one of confidence
and trust.  This  relationship and the rights granted and duties imposed by this
Section  shall  continue  until a date ten (10) years  from the date  Employee's
employment is terminated.

     7.2  As  used  in  this  Agreement  (i)  "Confidential  Information"  means
information  disclosed  to or acquired by Employee  about the  Company's  plans,
products,  processes and services,  including  information relating to research,
development,  inventions,  manufacturing,  purchasing, accounting,  engineering,
marketing,  merchandising,  selling,  pricing,  tariffed or  contractual  terms,
customer lists and prospect lists and other market information,  with respect to


                                       4
<PAGE>

any of the  Company's  business  activities;  and (ii)  "Inventions"  means  any
inventions,   discoveries,  concepts  and  ideas,  whether  patentable  or  not,
including, without limitation,  processes, methods, formulas, and techniques (as
well as  related  improvements  and  knowledge)  that are based on or related to
Confidential   Information,   that  pertain  in  any  manner  to  the  Company's
technology,  expertise  or business  and that are made or conceived by Employee,
either solely or jointly with others, and while employed by the Company, whether
or not made or conceived  during  working hours or with the use of the Company's
facilities, materials or personnel.

     7.3  Employee  agrees  that he  shall  at no time  during  the Term of this
Agreement or at any time thereafter disclose any Confidential Information to any
person,  firm or  corporation  to any extent or for any reason or purpose or use
any  Confidential  Information  for any  purpose  other than the  conduct of the
Company's  business,  unless such  Confidential  Information  has been  publicly
disclosed by the Company or a third party.

     7.4 Any Confidential Information that is directly or indirectly originated,
developed  or  perfected  to any  degree  by  Employee  during  the  term of his
employment  by the Company  shall be and remain the sole property of the Company
and shall be deemed trade secrets of the Company.

     7.5  Upon  termination  of  Employee's  employment  pursuant  to any of the
provisions  herein,  Employee or his legal  representative  shall deliver to the
Company  all  originals  and all  duplicates  and/or  copies  of all  documents,
records,  notebooks,  and similar  repositories  of or  containing  Confidential
Information then in his possession, whether prepared by him or not.

     7.6 Employee  agrees that the  covenants and  agreements  contained in this
Section 7 are fair and  reasonable  and that no waiver or  modification  of this
Section or any covenant or condition  set forth herein shall be valid unless set
forth in writing and duly executed by the parties hereto.

     8.  Injunctive  Relief.  Upon a material  breach by  Employee of any of the
provisions of Sections 6 or 7 of this  Agreement,  the Company shall be entitled
to an injunction  restraining Employee from such breach. Nothing herein shall be
construed as  prohibiting  the Company from pursuing any other remedies for such
breach, including recovery of damages from Employee.

     9. No Waiver.  A waiver by the Company of a breach of any provision of this
Agreement  by  Employee  shall not  operate or be  construed  as a waiver of any
subsequent or other breach by Employee.

     10.  Severability.  It is the  desire and  intent of the  parties  that the
provisions of this Agreement shall be enforced to the fullest extent permissible
under  the  laws and  public  policies  applied  in each  jurisdiction  in which
enforcement is sought.  Accordingly,  if any particular  provision or portion of
this  Agreement  shall be  adjudicated  to be  invalid  or  unenforceable,  this
Agreement  shall  be  deemed  amended  to  delete  therefrom  the  portion  thus
adjudicated  to be invalid or  unenforceable,  such  deletion to apply only with
respect to the operation of such  provision in the  particular  jurisdiction  in
which such adjudication is made.

     11.  Gross-Up  Payment.  In the event it is determined  that any payment or
distribution of any type to or for the benefit of the Employee, pursuant to this
Agreement or  otherwise,  by the Company,  any person who acquires  ownership or
effective control of the Company,  or ownership of a substantial  portion of the
assets of the  Company  (within  the  meaning  of section  260G of the  Internal
Revenue Code ("Code") and the  regulations  thereunder) or any affiliate of such


                                       5
<PAGE>

person  (the  "Total  Payments')  would be subject to the excise tax  imposed by
Section  4999 of the Code or any such  interest and  penalties,  with respect to
such excise tax (such excise tax,  together  with any interest and penalties are
collectively  referred  to as the  "Excise  Tax"),  then the  Employee  shall be
entitled to receive an  additional  payment (a "Gross-Up  Payment") in an amount
such that, after payment by the Employee of all taxes (including any interest or
penalties imposed with respect to such taxes), including any Excise Tax, imposed
upon the  Gross-Up  Payment,  the  Employee  retains  an amount of the  Gross-Up
Payment equal to the Excise Tax imposed upon the Total Payment.

     12.  Determination  by  Accountant.  All  mathematical  determinations  and
determinations as to whether any of the Total Payments are "parachute  payments"
(within  the  meaning  of  Section  280G  of  the  Code),  in  each  case  which
determinations  are required to be made under this Section 12, including whether
a Gross-Up Payment is required, the amount of such Gross-Up Payment, and amounts
relevant  to the  last  sentence  of  this  Section  12,  shall  be  made  by an
independent  accounting firm selected by the Employee from among the largest six
accounting  firms in the United States (the "Accounting  Firm").  The Accounting
Firm shall  provide to the Company and to the  Employee its  determination  (the
"Determination"),  together with detailed supporting  calculations regarding the
amount of any Gross-Up  Payment and any other relevant  matter,  within ten (10)
days after termination of the Employee's employment,  if applicable,  or at such
earlier time following termination of employment as is requested by the Employee
(if the  Employee  reasonably  believes  that any of the Total  Payments  may be
subject to the Excise Tax). If the Accounting Firm determines that no Excise Tax
is  payable  by the  Employee,  it shall  furnish  the  Employee  with a written
statement that such  Accounting Firm has concluded that no Excise Tax is payable
(including the reasons therefor) and that the Employee has substantial authority
not to report any Excise Tax on the Employee's  federal income tax return.  If a
Gross-Up  Payment is determined to be payable,  it shall be paid to the Employee
within ten (10) days after the  Determination is delivered to the Company or the
Employee.  Any  determination  by the Accounting  Firm shall be binding upon the
Company and the Employee, absent manifest error.

     As a result of uncertainty  in the  application of Section 4999 of the Code
at the time of the initial determination by the Accounting Firm hereunder, it is
possible  that  Gross-Up  Payments  not made by the  Company  and members of the
Company should have been made  ("Underpayment"),  or that Gross-Up Payments will
have been made by the Company  and  members of the Company  that should not have
been made  ("Overpayments").  In either such event,  the  Accounting  Firm shall
determine the amount of the  underpayment or Overpayment  that has occurred.  In
the case of an  Underpayment,  the  Company  promptly  shall pay, or cause to be
paid, the amount of such Underpayment to or for the benefit of the Employee.  In
the case of an Overpayment,  the Employee shall, at the direction and expense of
the Company,  take such steps as are reasonably  necessary (including the filing
of returns and claims for refund),  follow  reasonable  instructions  from,  and
procedures  established by the Company,  and otherwise reasonably cooperate with
the Company to correct such Overpayment;  provided,  however,  that (1) Employee
shall not in any event be obligated  to return to the Company an amount  greater
than the net  after-tax  portion  of the  Overpayment  that he has  retained  or
recovered  as a  refund  from the  applicable  taxing  authorities  and (2) this
provision shall be interpreted in a manner consistent with the intent of Section
11,  which  is to make the  Employee  whole,  on an  after-tax  basis,  from the
application  of the Excise Tax, it being  understood  that the  correction of an
Overpayment may result in the Employee repaying to the Company an amount that is
less than the Overpayment.

     13.  Notices.  All  communications,  requests,  consents and other  notices
provided for in this Agreement  shall be in writing and shall be deemed given if
delivered by hand or mailed by first class mail,  postage  prepaid,  to the last
known address of the recipient.

                                       6

     14.  Governing Law;  Arbitration.  This Agreement  shall be governed by and
construed and enforced in accordance with the laws of the State of Colorado. Any
dispute  or  controversy  arising  out  of  the  Employee's  employment  or  the
termination thereof,  including, but not limited to, any claim of discrimination
under state or federal law,  shall be settled  exclusively by arbitration in San
Jose,  California,  in  accordance  with the rules of the  American  Arbitration
Association then in effect. Judgment may be entered on the arbitrator's award in
any court having jurisdiction.

     15.  Assignment.  Neither this Agreement nor any rights or duties hereunder
may be assigned by Employee or the Company  without the prior written consent of
the other, such consent not to be unreasonably withheld.

     16. Amendments.  No provision of this Agreement shall be altered,  amended,
revoked or waived except by an  instrument  in writing,  signed by each party to
this Agreement.

     17. Binding Effect.  Except as otherwise  provided  herein,  this Agreement
shall be binding  upon and shall inure to the benefit of the parties  hereto and
their respective legal representatives, heirs, successors (including pursuant to
mergers) and assigns.

     18. Execution in Counterparts. This Agreement may be executed in any number
of  counterparts,  each of which shall be deemed an  original,  but all of which
together shall constitute one and the same instrument.

     19. Entire  Agreement.  This Agreement sets forth the entire  agreement and
understanding of the parties and supersedes all prior understandings, agreements
or  representations  by or between the parties,  whether written or oral,  which
relate in any way to the subject matter hereof.

     IN WITNESS WHEREOF, the parties have executed this Agreement as of the date
first above written.

                        AMOUNTS AND TERMS OF THE ADVANCES
                            AND THE LETTERS OF CREDIT

     SECTION  2.01.  The Advances  and the Letters of Credit.  (a) The Tranche A
Term Advances.  Each Tranche A Term Lender  severally  agrees,  on the terms and
conditions  hereinafter set forth, to make advances (a "Tranche A Term Advance")
to the  Appropriate  Borrower  on the  Effective  Date  and,  from  time to time
thereafter,  on any Business Day during the period from the Effective Date until
August 10, 2000 in an amount for each such  Advance not to exceed such  Lender's
Unused  Tranche A Term  Commitment at such time.  Each Tranche A Term  Borrowing
shall be in an  aggregate  amount  of  $5,000,000  or an  integral  multiple  of
$1,000,000  in excess  thereof and shall consist of Tranche A Term Advances made
simultaneously  by the Tranche A Term Lenders ratably according to their Tranche
A Term  Commitments.  Amounts  borrowed under this Section 2.01(a) and repaid or
prepaid may not be reborrowed.

     (b) The  Tranche B Term  Advances.  Each  Tranche B Term  Lender  severally
agrees,  on the terms and  conditions  hereinafter  set forth,  to make a single
advance (a "Tranche B Term  Advance") to the Borrowers on the Effective  Date in
an amount not to exceed such  Lender's  Tranche B Term  Commitment at such time.
The  Tranche B Term  Borrowing  shall  consist of Tranche B Term  Advances  made
simultaneously  by the Tranche B Term Lenders ratably according to their Tranche
B Term  Commitments.  Amounts  borrowed under this Section 2.01(b) and repaid or
prepaid may not be reborrowed.

     (c) The Working Capital  Advances.  Each Working  Capital Lender  severally
agrees,  on the terms and  conditions  hereinafter  set forth,  to make advances
(each a "Working Capital Advance") to the Appropriate Borrower from time to time
on any Business Day during the period from the Effective  Date until the Working
Capital  Termination  Date in an amount for each such Advance not to exceed such
Lender's  Unused Working  Capital  Commitment at such time. Each Working Capital
Borrowing shall be in an aggregate amount of $1,000,000 or an integral  multiple
of $500,000 in excess  thereof  (other  than a Borrowing  the  proceeds of which
shall be used  solely to repay or prepay  in full  outstanding  Letter of Credit
Advances) and shall consist of Working Capital Advances made  simultaneously  by
the  Working  Capital  Lenders  ratably   according  to  their  Working  Capital
Commitments.  Within the limits of each Working Capital  Lender's Unused Working
Capital  Commitment in effect from time to time,  each Borrower may borrow under
this Section 2.01(c), prepay pursuant to Section 2.06(a) and reborrow under this
Section 2.01(c).

     (d) The  Letters of  Credit.  The  Issuing  Bank  agrees,  on the terms and
conditions  hereinafter  set forth,  to issue (or cause its Affiliate  that is a
commercial  bank to issue on its  behalf)  letters of credit  (the  "Letters  of
Credit") for the account of the  Appropriate  Borrower  from time to time on any
Business Day during the period from the Effective  Date until 60 days before the
Working Capital  Termination  Date in an aggregate  Available Amount (i) for all
Letters  of Credit  not to exceed  at any time the  lesser of (x) the  Letter of
Credit  Facility  at such  time and (y) the  Issuing  Bank's  Letter  of  Credit
Commitment at such time and (ii) for each such Letter of Credit not to exceed an
amount equal to the Unused Working  Capital  Commitments of the Working  Capital
Lenders  at such  time.  No Letter  of  Credit  shall  have an  expiration  date
(including all rights of the Appropriate  Borrower or the beneficiary to require



                                       29
<PAGE>

renewal)  later  than  the  earlier  of  60  days  before  the  Working  Capital
Termination  Date and (A) in the case of a Standby  Letter of  Credit,  one year
after the date of issuance thereof,  but may by its terms be renewable  annually
upon  notice  (a  "Notice  of  Renewal")  given  to the  Issuing  Bank  and  the
Administrative  Agent on or prior to any date for notice of renewal set forth in
such Letter of Credit but in any event at least three Business Days prior to the
date  of the  proposed  renewal  of such  Standby  Letter  of  Credit  and  upon
fulfillment  of the  applicable  conditions  set forth in Article III unless the
Issuing  Bank  has  notified  the  Appropriate  Borrower  (with  a  copy  to the
Administrative  Agent)  on or prior to the date for  notice of  termination  set
forth in such Letter of Credit but in any event at least 30 Business  Days prior
to the date of  automatic  renewal of its  election  not to renew  such  Standby
Letter of  Credit (a  "Notice  of  Termination")  and (B) in the case of a Trade
Letter of Credit, 60 days after the date of issuance thereof;  provided that the
terms of each Standby Letter of Credit that is automatically  renewable annually
shall (x) require the Issuing Bank to give the beneficiary named in such Standby
Letter  of  Credit  notice  of  any  Notice  of  Termination,  (y)  permit  such
beneficiary,  upon receipt of such notice,  to draw under such Standby Letter of
Credit prior to the date such Standby Letter of Credit otherwise would have been
automatically  renewed  and (z) not permit the  expiration  date  (after  giving
effect  to any  renewal)  of such  Standby  Letter  of Credit in any event to be
extended  to a date later than 60 days before the  Working  Capital  Termination
Date. If either a Notice of Renewal is not given by the Appropriate  Borrower or
a Notice of Termination is given by the Issuing Bank pursuant to the immediately
preceding  sentence,  such Standby  Letter of Credit shall expire on the date on
which it otherwise would have been  automatically  renewed;  provided,  however,
that even in the absence of receipt of a Notice of Renewal the Issuing  Bank may
in its discretion, unless instructed to the contrary by the Administrative Agent
or the  Appropriate  Borrower,  deem that a Notice of  Renewal  had been  timely
delivered  and in such case, a Notice of Renewal shall be deemed to have been so
delivered for all purposes under this  Agreement.  Each Standby Letter of Credit
shall  contain a  provision  authorizing  the  Issuing  Bank to  deliver  to the
beneficiary  of such  Letter of  Credit,  upon the  occurrence  and  during  the
continuance of an Event of Default,  a notice (a "Default  Termination  Notice")
terminating  such Letter of Credit and giving such  beneficiary  15 days to draw
such Letter of Credit.  Within the limits of the Letter of Credit Facility,  and
subject to the limits referred to above,  each Borrower may request the issuance
of Letters  of Credit  under this  Section  2.01(d),  repay any Letter of Credit
Advances  resulting  from drawings  thereunder  pursuant to Section  2.03(c) and
request the issuance of additional Letters of Credit under this Section 2.01(d).

     SECTION  2.02.  Making the  Advances.  (a) Except as otherwise  provided in
Section 2.02(b) or 2.03, each Borrowing shall be made on notice, given not later
than 11:00 A.M. (New York City time) on the third Business Day prior to the date
of the proposed  Borrowing in the case of a Borrowing  consisting  of Eurodollar
Rate  Advances,  or the first  Business  Day  prior to the date of the  proposed
Borrowing in the case of a Borrowing consisting of Base Rate Advances, by either
Borrower  to the  Administrative  Agent,  which  shall give to each  Appropriate
Lender  prompt  notice  thereof by telex or  telecopier.  Each such  notice of a
Borrowing (a "Notice of Borrowing") shall be by telephone, confirmed immediately
in  writing,  or telex or  telecopier,  in  substantially  the form of Exhibit B
hereto, specifying therein the requested (i) name of such Borrower, (ii) date of
such  Borrowing,  (ii) Facility under which such Borrowing is to be made,  (iii)
Type of  Advances  comprising  such  Borrowing,  (iv)  aggregate  amount of such
Borrowing  and (v) in the case of a  Borrowing  consisting  of  Eurodollar  Rate
Advances, initial Interest Period for each such Advance. Each Appropriate Lender
shall,  before  11:00 A.M.  (New York City time) on the date of such  Borrowing,
make  available  for  the  account  of  its  Applicable  Lending  Office  to the
Administrative  Agent at the Administrative  Agent's Account, in same day funds,
such  Lender's  ratable  portion  of  such  Borrowing  in  accordance  with  the
respective  Commitments  under the  applicable  Facility  of such Lender and the


                                       30
<PAGE>

other  Appropriate  Lenders.  After the  Administrative  Agent's receipt of such
funds and upon  fulfillment  of the  applicable  conditions set forth in Article
III, the Administrative  Agent will make such funds available to the Appropriate
Borrower by  crediting  the  Appropriate  Borrower's  Account in same day funds;
provided,  however,  that,  in the case of any Working  Capital  Borrowing,  the
Administrative  Agent  shall  first make a portion  of such  funds  equal to the
aggregate  principal amount of any Letter of Credit Advances made by the Issuing
Bank and by any other Working Capital Lender and outstanding on the date of such
Working Capital Borrowing, plus interest accrued and unpaid thereon to and as of
such date, available to such Issuing Bank and such other Working Capital Lenders
for repayment of such Letter of Credit Advances.

     (b)  Anything  in  subsection  (a) above to the  contrary  notwithstanding,
neither  Borrower  may  select  Eurodollar  Rate  Advances  (i) for any  initial
Borrowing  hereunder  and  during  the  period  from the  Effective  Date to the
Syndication Date (the  "Syndication  Period"),  provided,  however,  that either
Borrower may select  Eurodollar  Rate  Advances  for such  initial  Borrowing or
during the Syndication  Period, so long as such Borrower  indemnifies the Agents
and each Lender  Party in  accordance  with  Section  9.04(c)  and as  otherwise
provided  under the Loan  Documents,  (ii) for any  Borrowing  if the  aggregate
amount of such  Borrowing is less than  $1,000,000 or (iii) if the obligation of
the Appropriate Lenders to make Eurodollar Rate Advances shall then be suspended
pursuant to Section 2.09 or 2.10.

     (c) The Tranche A Advances may not be  outstanding as part of more than ten
separate Borrowings,  the Tranche B Term Advances may not be outstanding as part
of more than five separate Borrowing and the Working Capital Advances may not be
outstanding as part of more than ten separate Borrowings.

     (d) Each  Notice of  Borrowing  shall be  irrevocable  and  binding  on the
Appropriate  Borrower.  In the case of any Borrowing  that the related Notice of
Borrowing  specifies  is  to be  comprised  of  Eurodollar  Rate  Advances,  the
Borrowers  shall  indemnify each  Appropriate  Lender against any loss,  cost or
expense  incurred  by such  Lender as a result of any  failure  to fulfill on or
before the date  specified in such Notice of Borrowing  for such  Borrowing  the
applicable  conditions set forth in Article III, including,  without limitation,
any loss (including loss of anticipated  profits),  cost or expense  incurred by
reason of the liquidation or reemployment of deposits or other funds acquired by
such  Lender  to fund  the  Advance  to be made by such  Lender  as part of such
Borrowing  when such Advance,  as a result of such failure,  is not made on such
date.

     (e) Unless the  Administrative  Agent  shall have  received  notice from an
Appropriate  Lender prior to the date of any  Borrowing  under a Facility  under
which such Lender has a Commitment  that such Lender will not make  available to
the  Administrative  Agent such Lender's ratable portion of such Borrowing,  the
Administrative Agent may assume that such Lender has made such portion available
to the  Administrative  Agent on the date of such  Borrowing in accordance  with
subsection  (a) of this  Section  2.02  and the  Administrative  Agent  may,  in
reliance upon such  assumption,  make available to the  Appropriate  Borrower on
such date a  corresponding  amount.  If and to the extent that such Lender shall
not have so made such ratable  portion  available to the  Administrative  Agent,
such  Lender  and  such  Borrower  severally  agree  to  repay  or  pay  to  the
Administrative  Agent forthwith on demand such  corresponding  amount and to pay
interest  thereon,  for each day from the date such amount is made  available to
such Borrower until the date such amount is repaid or paid to the Administrative


                                       31
<PAGE>

Agent, at (i) in the case of such Borrower, the interest rate applicable at such
time under Section 2.07 to Advances  comprising  such  Borrowing and (ii) in the
case of such  Lender,  the Federal  Funds Rate.  If such Lender shall pay to the
Administrative  Agent  such  corresponding  amount,  such  amount so paid  shall
constitute such Lender's Advance as part of such Borrowing for all purposes.

     (f) The  failure of any Lender to make the Advance to be made by it as part
of any Borrowing shall not relieve any other Lender of its  obligation,  if any,
hereunder to make its Advance on the date of such Borrowing, but no Lender shall
be  responsible  for the  failure of any other  Lender to make the Advance to be
made by such other Lender on the date of any Borrowing.

     SECTION 2.03.  Issuance of and Drawings and Reimbursement  Under Letters of
Credit.  (a) Request for  Issuance.  Each Letter of Credit  shall be issued upon
notice,  given not  later  than  11:00  A.M.  (New York City  time) on the fifth
Business  Day  prior to the date of the  proposed  issuance  of such  Letter  of
Credit,   by  a  Borrower  to  the  Issuing  Bank,   which  shall  give  to  the
Administrative  Agent and each Working  Capital  Lender prompt notice thereof by
telex or  telecopier.  Each  such  notice of  issuance  of a Letter of Credit (a
"Notice of Issuance") shall be by telephone,  confirmed  immediately in writing,
or  telex  or  telecopier,  specifying  therein  the  requested  (A) name of the
Borrower,  (B) date of such  issuance  (which  shall  be a  Business  Day),  (C)
Available Amount of such Letter of Credit, (D) expiration date of such Letter of
Credit, (E) name and address of the beneficiary of such Letter of Credit and (F)
form of such Letter of Credit,  and shall be accompanied by such application and
agreement for letter of credit as such Issuing Bank may specify to such Borrower
for use in connection with such requested  Letter of Credit (a "Letter of Credit
Agreement"). If (x) the requested form of such Letter of Credit is acceptable to
the Issuing Bank in its sole  discretion  and (y) it has not received  notice of
objection to issuance  from  Lenders  holding at least a majority of the Working
Capital  Commitments,  the Issuing Bank will, upon fulfillment of the applicable
conditions set forth in Article III, make such Letter of Credit available to the
Appropriate  Borrower at its office  referred to in Section 9.02 or as otherwise
agreed with such Borrower in connection with such issuance.  In the event and to
the extent that the provisions of any Letter of Credit  Agreement shall conflict
with this Agreement, the provisions of this Agreement shall govern.

     (b) Letter of Credit  Reports.  The Issuing  Bank shall  furnish (A) to the
Administrative  Agent on the first  Business  Day of each week a written  report
summarizing  issuance and  expiration  dates of Letters of Credit  issued by the
Issuing  Bank during the previous  week and drawings  during such week under all
Letters of Credit issued by the Issuing Bank, (B) to each Working Capital Lender
on the first  Business Day of each month a written report  summarizing  issuance
and expiration  dates of Letters of Credit issued by the Issuing Bank during the
preceding  month and  drawings  during  such month  under all  Letters of Credit
issued by the Issuing Bank and (C) to the Administrative  Agent and each Working
Capital  Lender on the first  Business  Day of each  calendar  quarter a written
report  setting forth the average daily  aggregate  Available  Amount during the
preceding calendar quarter of all Letters of Credit issued by the Issuing Bank.

     (c) Drawing and  Reimbursement.  The payment by the Issuing Bank of a draft
drawn  under any Letter of Credit  shall  constitute  for all  purposes  of this
Agreement the making by such Issuing Bank of a Letter of Credit  Advance,  which
shall be a Base Rate Advance,  in the amount of such draft.  Upon written demand
by the Issuing  Bank,  with a copy of such demand to the  Administrative  Agent,
each  Working  Capital  Lender shall  purchase  from the Issuing  Bank,  and the


                                       32
<PAGE>

Issuing Bank shall sell and assign to each such  Working  Capital  Lender,  such
Lender's Pro Rata Share of such  outstanding  Letter of Credit Advance as of the
date of such  purchase,  by making  available for the account of its  Applicable
Lending Office to the Administrative  Agent for the account of the Issuing Bank,
by deposit to the Administrative  Agent's Account,  in same day funds, an amount
equal to the  portion  of the  outstanding  principal  amount of such  Letter of
Credit Advance to be purchased by such Lender.  Promptly after receipt  thereof,
the  Administrative  Agent shall  transfer such funds to the Issuing Bank.  Each
Borrower  hereby agrees to each such sale and  assignment.  Each Working Capital
Lender agrees to purchase its Pro Rata Share of an outstanding  Letter of Credit
Advance on (i) the Business Day on which demand  therefor is made by the Issuing
Bank,  provided  that  notice of such  demand is given not later than 11:00 A.M.
(New York City time) on such Business  Day, or (ii) the first  Business Day next
succeeding  such demand if notice of such demand is given after such time.  Upon
any such  assignment  by the  Issuing  Bank to any Working  Capital  Lender of a
portion of a Letter of Credit Advance,  the Issuing Bank represents and warrants
to such other Lender that the Issuing Bank is the legal and beneficial  owner of
such interest  being  assigned by it, free and clear of any liens,  but makes no
other  representation or warranty and assumes no responsibility  with respect to
such Letter of Credit  Advance,  the Loan Documents or any Loan Party. If and to
the extent that any Working  Capital Lender shall not have so made the amount of
such  Letter of Credit  Advance  available  to the  Administrative  Agent,  such
Working  Capital  Lender  and  the  Borrowers  severally  agree  to  pay  to the
Administrative  Agent  forthwith on demand such amount  together  with  interest
thereon, for each day from the date of demand by the Issuing Bank until the date
such amount is paid to the  Administrative  Agent, at the Federal Funds Rate for
its account or the account of the Issuing  Bank, as  applicable.  If such Lender
shall pay to the Administrative Agent such amount for the account of the Issuing
Bank on any  Business  Day,  such amount so paid in respect of  principal  shall
constitute a Letter of Credit  Advance made by such Lender on such  Business Day
for purposes of this  Agreement,  and the  outstanding  principal  amount of the
Letter of Credit  Advance  made by the  Issuing  Bank  shall be  reduced by such
amount on such Business Day.

     (d) Failure to Make Letter of Credit Advances. The failure of any Lender to
make the  Letter of Credit  Advance  to be made by it on the date  specified  in
Section  2.03(c) shall not relieve any other Lender of its obligation  hereunder
to make its  Letter of  Credit  Advance  on such  date,  but no Lender  shall be
responsible  for the  failure  of any other  Lender to make the Letter of Credit
Advance to be made by such other Lender on such date.

     SECTION 2.04.  Repayment of Advances.  (a) Tranche A Term Advances.  On the
last Business Day of each calendar quarter  specified below, the Borrowers shall
jointly and severally repay to the Administrative  Agent for the ratable account
of the Tranche A Term Lenders an aggregate  outstanding  principal amount of the
Tranche A Term  Advances  (which  amounts  shall be  reduced  as a result of the
application  of  prepayments  in  accordance  with the  priorities  set forth in
Section 2.06) in twelve  consecutive  installments,  each such installment being

to be in equal principal amounts for each such quarterly date for such year):

specified  below,  the  Borrowers  shall  jointly  and  severally  repay  to the
Administrative  Agent for the ratable  account of the Tranche B Term Lenders the
aggregate  outstanding  principal  amount of the Tranche B Term Advances  (which
amounts  shall be  reduced  as a result of the  application  of  prepayments  in
accordance  with  the  order  of  priority  set  forth  in  Section  2.06) in 27
consecutive  installments,  each such  installment  being  payable  on each such
quarterly date during each year indicated below (such  installments to aggregate
for such year to the  percentage  set  opposite  such year of the Tranche B Term
Advances  outstanding on the Effective Date and to be in equal principal amounts
for each such quarterly date for such year):


                    Calendar Quarter                             Percentage

From and including the third quarter of 1999 to and                  1%

Tranche B  Termination  Date and in any event shall be in an amount equal to the
aggregate  principal  amount of the Tranche B Term Advances  outstanding on such
date.

     (c) Working  Capital  Advances.  The Borrowers  shall jointly and severally
repay to the Administrative Agent for the ratable account of the Working Capital
Lenders on the Working Capital  Termination Date the aggregate  principal amount
of the Working Capital Advances then outstanding.

severally repay to the Administrative  Agent for the account of the Issuing Bank
on the Working Capital Termination Date the outstanding principal amount of each

     (ii) The Obligations of the Borrowers  under this Agreement,  any Letter of
Credit Agreement and any other agreement or instrument relating to any Letter of
Credit shall be  unconditional  and  irrevocable,  and shall be paid strictly in
accordance with the terms of this Agreement, such Letter of Credit Agreement and
such other agreement or instrument under all circumstances,  including,  without
limitation,  the  following  circumstances  (it being  understood  that any such
payment by the  Borrowers  is without  prejudice  to, and does not  constitute a
waiver of, any rights the  Borrowers  might have or might acquire as a result of
the  payment  by the  Issuing  Bank of any  draft  or the  reimbursement  by the
Borrowers thereof):

                  (A)  any  lack  of  validity  or  enforceability  of any  Loan
         Document,  any Letter of Credit Agreement,  any Letter of Credit or any
         other  agreement or instrument  relating  thereto (all of the foregoing
         being, collectively, the "L/C Related Documents");

                  (B) any change in the time,  manner or place of payment of, or
         in any other term of, all or any of the  Obligations of any Borrower in
         respect of any L/C Related Document or any other amendment or waiver of
         or any  consent  to  departure  from  all or  any  of the  L/C  Related
         Documents;

                  (C) the  existence  of any  claim,  set-off,  defense or other
         right that any Borrower may have at any time against any beneficiary or
         any transferee of a Letter of Credit (or any Persons for which any such
         beneficiary or any such transferee may be acting),  the Issuing Bank or
         any  other  Person,   whether  in  connection  with  the   transactions
         contemplated by the L/C Related Documents or any unrelated transaction;

                  (D) any  statement  or any other  document  presented  under a
         Letter  of  Credit  proving  to  be  forged,  fraudulent,   invalid  or

         inaccurate in any respect;

                  (E)  payment  by the  Issuing  Bank  under a Letter  of Credit
         against  presentation of a draft or certificate  that does not strictly
         comply with the terms of such Letter of Credit;

                  (F) any exchange,  release or non-perfection of any Collateral
         or other  collateral,  or any  release  or  amendment  or  waiver of or
         consent to departure  from the Guaranties or any other  guarantee,  for
         all or any of the  Obligations  of any  Borrower  in respect of the L/C
         Related Documents; or

                  (G) any other circumstance or happening whatsoever, whether or
         not similar to any of the foregoing, including, without limitation, any
         other circumstance that might otherwise  constitute a defense available
         to, or a discharge of, any Loan Party or a guarantor.

     SECTION 2.05.  Termination or Reduction of the  Commitments.  (a) Optional.
The  Borrowers   may,   upon  at  least  five  Business   Days'  notice  to  the
Administrative  Agent  terminate in whole or reduce in part the Unused Tranche A
Term Commitments and the Unused Working Capital Commitments;  provided, however,
that each  partial  reduction  of the  Commitments  (i) shall be in an aggregate
amount of $5,000,000 or an integral multiple of $1,000,000 in excess thereof and
(ii) shall be made ratably  among the  Appropriate  Lenders in  accordance  with


                                       35
<PAGE>

their Commitments with respect to such Facility. For the avoidance of doubt, the
termination  or reduction  of the Unused  Tranche A  Commitments  and the Unused
Working Capital  Commitments  pursuant to the preceding sentence shall be deemed
to be a  termination  or  reduction,  as  applicable,  in  the  amount  of  such
termination  or  reduction  of the  Tranche A Term  Commitments  or the  Working
Capital Commitment, as the case may be.

     (b)  Mandatory.  The  Facilities  shall be  automatically  and  permanently
reduced on each date a  prepayment  thereof is required  to be made  pursuant to
Section  2.06(b)(i) or (ii) in an amount equal to the amount of such prepayment,
provided that such reduction of the  Facilities  shall be made ratably among the
Appropriate Lenders in accordance with their relevant  Commitments in accordance
with the priorities pursuant to Section 2.06(b).

     SECTION 2.06.  Prepayments.  (a) Optional.  Subject to Section 5.03(a)(ii),
the Borrowers  may, upon at least one Business  Day's notice in the case of Base
Rate Advances and three  Business  Days' notice in the case of  Eurodollar  Rate
Advances, in each case to the Administrative Agent stating the proposed date and
aggregate  principal  amount of the prepayment,  and if such notice is given the
Borrowers  shall,  jointly  and  severally  prepay  the  outstanding   aggregate
principal amount of the Advances  comprising part of the same Borrowing in whole
or  ratably  in  part,  together  with  accrued  interest  to the  date  of such
prepayment on the aggregate principal amount prepaid;  provided,  however,  that
(x)  each  partial  prepayment  shall be in an  aggregate  principal  amount  of
$5,000,000 or an integral  multiple of $1,000,000 in excess thereof;  and (y) if
any  prepayment  of a  Eurodollar  Rate Advance is made on a date other than the
last day of an Interest  Period for such Advance,  the Borrowers  shall also pay
any amounts owing pursuant to Section  9.04(c).  Each such  prepayment  shall be
applied ratably first to the Term Facilities and to the installments thereof pro
rata and second to the Working  Capital  Facility as set forth in clause (b)(iv)
below.

     (b)  Mandatory.  (i)  Commencing  with the Fiscal Year ending  December 31,
2002,  the  Borrowers  shall,  on the 90th day  following the end of such Fiscal
Year, jointly and severally prepay an aggregate principal amount of the Advances
comprising part of the same Borrowings and, thereafter, deposit an amount in the
L/C Cash Collateral  Account,  in an amount equal to 50% of the amount of Excess
Cash Flow for such Fiscal Year.  Each such  prepayment  shall be applied ratably
first to the Term Facilities and to the installments thereof pro rata and second
to the Working Capital Facility as set forth in clause (iv) below.

     (ii) The Borrowers  shall,  on the date of receipt of the Net Cash Proceeds
by any Borrower or any of their Subsidiaries from (A) the sale, lease,  transfer
or other  disposition  of any assets of any Borrower or any of its  Subsidiaries
(other than any sale, lease, transfer or other disposition of assets pursuant to
clause (i), (ii), or (iv) of Section 5.02(e)) and (B) any Extraordinary  Receipt
received  by or paid to or for  the  account  of any  Borrower  or any of  their
Subsidiaries  and not  otherwise  included  in clause  (A)  above,  jointly  and
severally prepay an aggregate  principal amount of the Advances  comprising part
of the same  Borrowings  and,  thereafter,  deposit  an  amount  in the L/C Cash
Collateral  Account, in an amount equal to the amount of such Net Cash Proceeds.
Each such  prepayment  shall be applied ratably first to the Term Facilities and
to the installments  thereof pro rata and second to the Working Capital Facility
as set forth in clause (iv) below.

     (iii) The Borrowers  shall, on each Business Day, jointly and severally pay
to the  Administrative  Agent for deposit in the L/C Cash Collateral  Account an


                                       36
<PAGE>

amount  sufficient  to cause the  aggregate  amount on  deposit  in the L/C Cash
Collateral  Account to equal the amount by which the aggregate  Available Amount
of all Letters of Credit then outstanding  exceeds the Letter of Credit Facility
on such Business Day.

     (iv)  Prepayments of the Working  Capital  Facility made pursuant to clause
(i) and (ii) above shall be first  applied to prepay  Letter of Credit  Advances
then outstanding  until such Advances are paid in full, second applied to prepay
Working Capital Advances then outstanding comprising part of the same Borrowings
until  such  Advances  are  paid in full  and  third  deposited  in the L/C Cash
Collateral  Account to cash  collateralize  100% of the Available  Amount of the
Letters of Credit  then  outstanding;  and,  in the case of  prepayments  of the
Working  Capital  Facility  required  pursuant to clause (i) or (ii) above,  the
amount  remaining  (if any) after the  prepayment  in full of the Advances  then
outstanding  and the 100%  cash  collateralization  of the  aggregate  Available
Amount  of  Letters  of  Credit  then  outstanding  (the sum of such  prepayment
amounts, cash  collateralization  amounts and remaining amount being referred to
herein as the  "Reduction  Amount")  may be  retained by the  Borrowers  and the
Working  Capital  Facility shall be permanently  reduced as set forth in Section
2.05(b). Upon the drawing of any Letter of Credit for which funds are on deposit
in the L/C Cash Collateral Account, such funds shall be applied to reimburse the
Issuing Bank.

     (v) All  prepayments  under this subsection (b) shall be made together with
accrued interest to the date of such prepayment on the principal amount prepaid.
If any payment of Eurodollar Rate Advances  otherwise  required to be made under
this  Section  2.06(b)  would  be made on a day  other  than the last day of the
applicable Interest Period therefor, the Borrowers may direct the Administrative
Agent to (and if so  directed,  the  Administrative  Agent  shall)  deposit such
payment  in the Cash  Collateral  Account  until the last day of the  applicable
Interest Period at which time the Administrative Agent shall apply the amount of
such payment to the prepayment of such Advances;  provided,  however,  that such
Advances  shall continue to bear interest as set forth in Section 2.07 until the
last day of the applicable Interest Period therefor.

     (c) Term B Opt-Out. The Administrative Agent shall promptly forward to each
Term B  Lender  each  Prepayment  Notice  received  by it  pursuant  to  Section
5.03(a)(ii).   With  respect  to  any  prepayment  of  the  Term  Advances,  the
Administrative  Agent  shall  ratably  pay the  Tranche A Term  Lenders  and the
Tranche B Term Lenders;  provided,  however,  that any Tranche B Term Lender, at
its option, to the extent that any Tranche A Term Advances are then outstanding,
may  elect  not to  accept  such  prepayment  (such  Lender  being a  "Declining
Lender"),  in which event the provisions of the next sentence  shall apply.  Any
Tranche  B Term  Lender  may  elect  not to  accept  its  ratable  share  of the
prepayment  referred to in any Prepayment Notice by giving written notice to the
Administrative  Agent not later  than  11:00  A.M.  (New York City  time) on the
fourth Business Day immediately  preceding the scheduled Prepayment Date. On the
Prepayment  Date,  an amount  equal to that  portion  of the  Prepayment  Amount
available  to  prepay  Tranche  B Term  Lenders  (less any  amounts  that  would
otherwise be payable to Declining  Lenders) shall be applied to prepay Tranche B
Term Advances owing to Tranche B Term Lenders other than  Declining  Lenders and
any amounts  that would  otherwise  have been  applied to prepay  Tranche B Term
Advances owing to Declining  Lenders shall instead be applied  ratably to prepay
the remaining  Tranche A Term Advances as provided in Sections  2.06(a) and (b);
provided,  further that on  prepayment  in full of Term  Advances  owing to Term
Lenders other than Declining  Lenders,  the remainder of any  Prepayment  Amount
shall be applied  ratably to prepay  Tranche B Term Advances  owing to Declining
Lenders.

     SECTION 2.07. Interest. (a) Scheduled Interest. The Borrowers shall jointly
and severally pay interest on the unpaid  principal amount of each Advance owing

be paid in full, at the following rates per annum:

          (i) Base Rate Advances.  During such periods as such Advance is a Base
     Rate  Advance,  a rate per  annum  equal at all times to the sum of (A) the

     each  quarter  during such  periods and on the date such Base Rate  Advance
     shall be Converted or paid in full.

          (ii) Eurodollar Rate Advances.  During such periods as such Advance is
     a Eurodollar Rate Advance,  a rate per annum equal at all times during each
     Interest  Period for such Advance to the sum of (A) the Eurodollar Rate for
     such  Interest  Period for such Advance plus (B) the  Applicable  Margin in
     effect  from  time to  time,  payable  in  arrears  on the last day of such
     Interest  Period and, if such  Interest  Period has a duration of more than
     three months,  on each day that occurs  during such  Interest  Period every
     three  months  from the first day of such  Interest  Period and on the date
     such Eurodollar Rate Advance shall be Converted or paid in full.

     (b) Default  Interest.  Upon the occurrence and during the continuance of a
payment or  bankruptcy  Default or any Event of  Default,  each  Borrower  shall
jointly and  severally pay interest on (i) the unpaid  principal  amount of each
Advance  owing to each  Lender,  payable in arrears on the dates  referred to in
clause (a)(i) or (a)(ii)  above and on demand,  at a rate per annum equal at all
times to 2% per  annum  above  the rate per  annum  required  to be paid on such
Advance  pursuant  to clause  (a)(i) or  (a)(ii)  above and (ii) to the  fullest
extent permitted by law, the amount of any interest, fee or other amount payable
under the Loan  Documents  that is not paid when due,  from the date such amount
shall be due until such amount shall be paid in full,  payable in arrears on the
date such amount shall be paid in full and on demand,  at a rate per annum equal
at all times to 2% per annum above the rate per annum  required  to be paid,  in
the case of interest,  on the Type of Advance on which such interest has accrued
pursuant to clause (a)(i) or (a)(ii) above and, in all other cases, on Base Rate
Advances pursuant to clause (a)(i) above.

     (c) Notice of Interest Period and Interest Rate.  Promptly after receipt of
a Notice of  Borrowing  pursuant  to  Section  2.02(a),  a notice of  Conversion
pursuant to Section 2.09 or a notice of selection of an Interest Period pursuant
to the terms of the definition of "Interest Period",  the  Administrative  Agent
shall give notice to the Appropriate Borrower and each Appropriate Lender of the
applicable  Interest  Period and the applicable  interest rate determined by the
Administrative Agent for purposes of clause (a)(i) or (a)(ii) above.

     SECTION 2.08.  Fees.  (a) Commitment  Fee. The Borrowers  shall jointly and
severally  pay to the  Administrative  Agent for the  account  of the  Lenders a
commitment  fee, from the Effective  Date in the case of each Initial Lender and
from the effective date  specified in the Assignment and Acceptance  pursuant to
which it became a Lender in the case of each  other  Lender,  payable in arrears
quarterly on the last  Business Day of each calendar  quarter,  on the available
but Unused Tranche A Term  Commitment  (until August 10, 2000) and the available
but Unused Working Capital  Commitment  (until the Working  Capital  Termination
Date)  at the  rate  expressed  as  percentage  set  forth  below  opposite  the


                                       38
<PAGE>

percentage  per annum on the average  daily unused  portion of each  Appropriate
Lender's  aggregate  available  Tranche A Term  Commitments  and Working Capital
Commitments during such quarter:


      Percentage of Unused Commitments          Commitment Fee

                    >75%                            1.375%

                    <25%                            0.625%

provided,  however,  that any  commitment fee accrued with respect to any of the
Commitments  of a  Defaulting  Lender  during the period  prior to the time such
Lender  became a Defaulting  Lender and unpaid at such time shall not be payable
by the  Borrowers so long as such Lender shall be a Defaulting  Lender except to
the extent that such commitment fee shall otherwise have been due and payable by
the  Borrowers  prior to such  time;  and  provided  further,  however,  that no
commitment fee shall accrue on any of the Commitments of a Defaulting  Lender so
long as such Lender shall be a Defaulting Lender.

     (b)  Letter of Credit  Fees,  Etc.  (i) The  Borrowers  shall  jointly  and
severally  pay to the  Administrative  Agent  for the  account  of each  Working
Capital Lender a commission,  payable in arrears  quarterly on the last Business
Day of each calendar quarter,  and on the earliest to occur of the full drawing,
expiration,  termination  or  cancellation  of any  Letter of Credit  and on the
Working Capital Termination Date, on such Lender's Pro Rata Share of the average
daily aggregate  Available Amount during such quarter of (A) all Standby Letters
of Credit outstanding from time to time at a rate equal to the Applicable Margin
in effect from day to day for Eurodollar Rate Advances under the Working Capital
Facility and (B) all Trade Letters of Credit then outstanding at a rate equal to
the  Applicable  Margin in effect from day to day for  Eurodollar  Rate Advances
under the Working Capital Facility.

     (ii) The Borrowers shall jointly and severally pay to the Issuing Bank, for
its own account,  such commissions,  issuance fees, fronting fees, transfer fees
and other fees and charges in connection with the issuance or  administration of
each Letter of Credit as the Borrowers and the Issuing Bank shall agree.

     (c) Agents'  Fees.  The  Borrowers  shall jointly and severally pay to each
Agent for its own account  such fees as may from time to time be agreed  between
the Borrower and such Agent.

     SECTION  2.09.  Conversion  of  Advances.  (a)  Optional.  The  Appropriate
Borrower may on any Business Day, upon notice given to the Administrative  Agent
not later than 11:00 A.M.  (New York City time) on the third  Business Day prior
to the date of the proposed  Conversion and subject to the provisions of Section
2.07 and Section  2.10,  Convert all or any portion of the  Advances of one Type
comprising  the same  Borrowing  into  Advances  of the  other  Type;  provided,
however, that any Conversion of Eurodollar Rate Advances into Base Rate Advances
shall be made only on the last day of an  Interest  Period  for such  Eurodollar
Rate  Advances,  any  Conversion  of Base Rate  Advances  into  Eurodollar  Rate
Advances  shall be in an amount not less than the minimum  amount  specified  in
Section  2.02(c),  no Conversion  of any Advances  shall result in more separate


                                       39
<PAGE>

Borrowings  than permitted under Section 2.02(c) and each Conversion of Advances
comprising  part of the same Borrowing  under any Facility shall be made ratably
among the Appropriate  Lenders in accordance with their  Commitments  under such
Facility.  Each  such  notice  of  Conversion  shall,  within  the  restrictions
specified above,  specify (i) the date of such Conversion,  (ii) the Advances to
be Converted and (iii) if such Conversion is into Eurodollar Rate Advances,  the
duration  of the  initial  Interest  Period for such  Advances.  Each  notice of
Conversion shall be irrevocable and binding on such Borrower.

     (b)  Mandatory.  (i) On the date on which the  aggregate  unpaid  principal
amount of Eurodollar Rate Advances comprising any Borrowing shall be reduced, by
payment or prepayment or otherwise, to less than $1,000,000, such Advances shall
automatically Convert into Base Rate Advances.

     (ii) If the  Appropriate  Borrower shall fail to select the duration of any
Interest  Period  for any  Eurodollar  Rate  Advances  in  accordance  with  the
provisions contained in the definition of "Interest Period" in Section 1.01, the
Administrative  Agent will forthwith so notify such Borrower and the Appropriate
Lenders, whereupon each such Eurodollar Rate Advance will automatically,  on the
last day of the then existing Interest Period therefor, Convert into a one month
Eurodollar Rate Advance.

     (iii) Upon the  occurrence and during the  continuance of any Default,  (x)
each  Eurodollar  Rate Advance will  automatically,  on the last day of the then
existing Interest Period therefor,  Convert into a Base Rate Advance and (y) the
obligation of the Lenders to make, or to Convert Advances into,  Eurodollar Rate
Advances shall be suspended.

     SECTION  2.10.  Increased  Costs,  Etc.  (a)  If,  due to  either  (i)  the
introduction  of or  any  change  in or in  the  interpretation  of  any  law or
regulation or (ii) the compliance with any guideline or request from any central
bank or other  governmental  authority (whether or not having the force of law),
there shall be any  increase in the cost to any Lender Party of agreeing to make
or of making,  funding or maintaining Eurodollar Rate Advances or of agreeing to
issue or of issuing or maintaining or  participating  in Letters of Credit or of
agreeing  to  make  or of  making  or  maintaining  Letter  of  Credit  Advances
(excluding,  for  purposes  of this  Section  2.10,  any  such  increased  costs
resulting  from (x) Taxes or Other Taxes (as to which Section 2.12 shall govern)
and (y) changes in the basis of taxation of overall net income or overall  gross
income by the United  States or by the foreign  jurisdiction  or state under the
laws of which such  Lender  Party is  organized  or has its  Applicable  Lending
Office or any political subdivision thereof), then the Borrowers shall from time
to time,  upon  demand by such  Lender  Party (with a copy of such demand to the
Administrative Agent), jointly and severally pay to the Administrative Agent for
the account of such Lender Party  additional  amounts  sufficient  to compensate
such Lender Party for such  increased  cost;  provided,  however,  that a Lender
Party  claiming  additional  amounts  under this Section  2.10(a)  agrees to use
reasonable efforts (consistent with its internal policy and legal and regulatory
restrictions) to designate a different  Applicable  Lending Office if the making
of such a  designation  would  avoid the need for, or reduce the amount of, such
increased  cost that may  thereafter  accrue  and would not,  in the  reasonable
judgment of such  Lender  Party,  be  otherwise  disadvantageous  to such Lender
Party. A certificate as to the amount of such increased cost, and the details of
the computation thereof,  submitted to the Borrowers by such Lender Party, shall
be conclusive and binding for all purposes, absent manifest error.

     (b) If,  due to either (i) the  introduction  of or any change in or in the
interpretation  of any  law or  regulation  or  (ii)  the  compliance  with  any

                                       40
<PAGE>

guideline  or request  from any  central  bank or other  governmental  authority
(whether  or not having the force of law),  there  shall be any  increase in the
amount of capital  required or expected to be  maintained by any Lender Party or
any corporation  controlling  such Lender Party as a result of or based upon the
existence of such Lender  Party's  commitment to lend or to issue or participate
in  Letters  of  Credit  hereunder  and  other  commitments  of such type or the
issuance or maintenance of or participation in the Letters of Credit (or similar
contingent  obligations),  then,  upon  demand  by  such  Lender  Party  or such
corporation  (with a copy of  such  demand  to the  Administrative  Agent),  the
Borrowers  shall jointly and severally pay to the  Administrative  Agent for the
account of such  Lender  Party,  from time to time as  specified  by such Lender
Party,  additional  amounts  sufficient to  compensate  such Lender Party in the
light of such  circumstances,  to the extent that such Lender  Party  reasonably
determines  such  increase in capital to be allocable  to the  existence of such
Lender  Party's  commitment  to lend or to issue or  participate  in  Letters of
Credit  hereunder or to the issuance or maintenance of or  participation  in any
Letters of Credit.  A  certificate  as to such  amounts,  and the details of the
computation  thereof,  submitted to the  Borrowers by such Lender Party shall be
conclusive and binding for all purposes, absent manifest error.

     (c) If, with respect to any  Eurodollar  Rate Advances  under any Facility,
Lenders owed at least 50% of the then aggregate  unpaid principal amount thereof
notify the Administrative Agent that the Eurodollar Rate for any Interest Period
for such  Advances  will not  adequately  reflect  the cost to such  Lenders  of
making,  funding or maintaining their Eurodollar Rate Advances for such Interest
Period, the Administrative Agent shall forthwith so notify the Borrowers and the
Appropriate Lenders,  whereupon (i) each such Eurodollar Rate Advance under such
Facility  will  automatically,  on the last day of the  then  existing  Interest
Period therefor, Convert into a Base Rate Advance and (ii) the obligation of the
Appropriate  Lenders  to make,  or to Convert  Advances  into,  Eurodollar  Rate
Advances  shall be  suspended  until the  Administrative  Agent shall notify the
Borrowers that such Lenders have determined that the circumstances  causing such
suspension no longer exist.

     (d)  Notwithstanding  any  other  provision  of  this  Agreement,   if  the
introduction  of or  any  change  in or in  the  interpretation  of  any  law or
regulation  shall make it unlawful,  or any central  bank or other  governmental
authority  shall  assert that it is unlawful,  for any Lender or its  Eurodollar
Lending  Office to perform its  obligations  hereunder to make  Eurodollar  Rate
Advances or to continue to fund or maintain  Eurodollar Rate Advances hereunder,
then,  on notice  thereof and demand  therefor  by such Lender to the  Borrowers
through the  Administrative  Agent,  (i) each Eurodollar Rate Advance under each
Facility under which such Lender has a Commitment will automatically,  upon such
demand,  Convert  into a Base  Rate  Advance  and  (ii)  the  obligation  of the
Appropriate  Lenders  to make,  or to Convert  Advances  into,  Eurodollar  Rate
Advances  shall be  suspended  until the  Administrative  Agent shall notify the
Borrowers that such Lender has determined  that the  circumstances  causing such
suspension  no longer exist;  provided,  however,  that,  before making any such
demand,  such  Lender  agrees to use  reasonable  efforts  (consistent  with its
internal policy and legal and regulatory  restrictions) to designate a different
Eurodollar  Lending Office if the making of such a designation  would allow such
Lender or its Eurodollar  Lending Office to continue to perform its  obligations
to make Eurodollar  Rate Advances or to continue to fund or maintain  Eurodollar
Rate  Advances  and would not, in the  judgment  of such  Lender,  be  otherwise
disadvantageous to such Lender.

     SECTION 2.11. Payments and Computations.  (a) The Borrowers shall make each
payment hereunder and under the Notes, irrespective of any right of counterclaim
or set-off (except as otherwise  provided in Section 2.15), not later than 11:00
A.M.  (New  York  City  time)  on the  day  when  due  in  U.S.  dollars  to the


                                       41
<PAGE>

Administrative  Agent at the  Administrative  Agent's Account in same day funds,
with payments being received by the  Administrative  Agent after such time being
deemed  to  have  been  received  on  the  next  succeeding  Business  Day.  The
Administrative Agent will promptly thereafter cause like funds to be distributed
(i) if such payment by any such Borrower is in respect of  principal,  interest,
commitment  fees or any other  Obligation  then payable  hereunder and under the
Notes to more than one Lender Party,  to such Lender  Parties for the account of
their  respective  Applicable  Lending  Offices  ratably in accordance  with the
amounts of such respective  Obligations  then payable to such Lender Parties and
(ii) if such payment by any such Borrower is in respect of any  Obligation  then
payable  hereunder to one Lender Party,  to such Lender Party for the account of
its Applicable Lending Office, in each case to be applied in accordance with the
terms of this Agreement. Upon its acceptance of an Assignment and Acceptance and
recording  of the  information  contained  therein in the  Register  pursuant to
Section  9.07(d),  from and  after the  effective  date of such  Assignment  and
Acceptance, the Administrative Agent shall make all payments hereunder and under
the Notes in  respect of the  interest  assigned  thereby  to the  Lender  Party
assignee  thereunder,  and the parties to such  Assignment and Acceptance  shall
make all  appropriate  adjustments  in such  payments for periods  prior to such
effective date directly between themselves.

     (b) The  Borrowers  hereby  authorize  each  Lender  Party  and each of its
Affiliates,  if and to the extent  payment owed to such Lender Party is not made
when due  hereunder  or,  in the case of a  Lender,  under the Note held by such
Lender,  to charge from time to time,  to the fullest  extent  permitted by law,
against any or all of the  Borrower's  accounts  with such Lender  Party or such
Affiliate any amount so due.

     (c) All  computations  of interest  based on the Base Rate shall be made by
the Administrative  Agent on the basis of a year of 365 or 366 days, as the case
may be, and all  computations  of interest based on the  Eurodollar  Rate or the
Federal Funds Rate and of fees and Letter of Credit commissions shall be made by
the  Administrative  Agent on the basis of a year of 360 days,  in each case for
the actual number of days  (including  the first day but excluding the last day)
occurring  in the  period  for which  such  interest,  fees or  commissions  are
payable. Each determination by the Administrative Agent of an interest rate, fee
or commission hereunder shall be conclusive and binding for all purposes, absent
manifest error.

     (d) Whenever any payment hereunder or under the Notes shall be stated to be
due on a day other than a Business  Day,  such payment shall be made on the next
succeeding  Business  Day,  and such  extension  of time  shall in such  case be
included in the  computation  of payment of interest or  commitment  fee, as the
case may be; provided,  however,  that, if such extension would cause payment of
interest on or  principal  of  Eurodollar  Rate  Advances to be made in the next
following  calendar  month,  such  payment  shall be made on the next  preceding
Business Day.

     (e) Unless the  Administrative  Agent shall have  received  notice from the
Borrowers  prior to the date on which any  payment  is due to any  Lender  Party
hereunder  that  any such  Borrower  will not make  such  payment  in full,  the
Administrative  Agent may assume that any such Borrower has made such payment in
full to the Administrative  Agent on such date and the Administrative Agent may,
in reliance upon such  assumption,  cause to be  distributed to each such Lender
Party on such due date an amount equal to the amount then due such Lender Party.
If and to the extent any such  Borrower  shall not have so made such  payment in
full to the  Administrative  Agent,  each such  Lender  Party shall repay to the


                                       42
<PAGE>

Administrative  Agent forthwith on demand such amount distributed to such Lender
Party together with interest thereon,  for each day from the date such amount is
distributed  to such Lender  Party until the date such Lender  Party repays such
amount to the Administrative Agent, at the Federal Funds Rate.

     (f) If the  Administrative  Agent  receives  funds for  application  to the
Obligations  under the Loan  Documents  under  circumstances  for which the Loan
Documents do not specify the Advances or the Facility to which, or the manner in
which, such funds are to be applied, the Administrative Agent may, but shall not
be obligated to, elect to distribute  such funds to each Lender Party ratably in
accordance with such Lender Party=s  proportionate share of the principal amount
of all  outstanding  Advances and the Available  Amount of all Letters of Credit
then outstanding, in repayment or prepayment of such of the outstanding Advances
or other  Obligations  owed to such Lender Party,  and for  application  to such
principal installments, as the Administrative Agent shall direct.

     SECTION 2.12. Taxes. (a) Any and all payments by the Borrowers hereunder or
under the Notes shall be made, in accordance  with Section 2.11,  free and clear
of and  without  deduction  for any and all  present  or future  taxes,  levies,
imposts, deductions,  charges or withholdings,  and all liabilities with respect
thereto,  excluding,  (i) in the case of each Lender Party and each Agent, taxes
that are imposed on its  overall net income by the United  States and taxes that
are imposed on its overall net income (and any franchise  taxes) by the state or
foreign jurisdiction under the laws of which such Lender Party or such Agent, as
the case may be, is organized or any political  subdivision thereof and, (ii) in
the case of each Lender Party,  taxes that are imposed on its overall net income
(and any franchise  taxes) by the state or foreign  jurisdiction  of such Lender
Party's Applicable Lending Office or any political subdivision thereof (all such
non-excluded  taxes,  levies,  imposts,  deductions,  charges,  withholdings and
liabilities  in  respect  of  payments   hereunder  or  under  the  Notes  being
hereinafter  referred to as "Taxes").  If the Borrowers shall be required by law
to deduct any Taxes from or in respect of any sum payable hereunder or under any
Note to any Lender  Party or any  Agent,  (i) the sum  payable by the  Borrowers
shall be  increased  as may be  necessary  so that after the  Borrowers  and the
Administrative  Agent have made all required  deductions  (including  deductions
applicable to additional sums payable under this Section 2.12) such Lender Party
or such Agent,  as the case may be, receives an amount equal to the sum it would
have received had no such  deductions  been made,  (ii) the Borrowers shall make
all such  deductions and (iii) the Borrowers  shall pay the full amount deducted
to the  relevant  taxation  authority  or other  authority  in  accordance  with
applicable law.

     (b) In  addition,  the  Borrowers  shall pay any  present or future  stamp,
documentary,  excise,  property or similar  taxes,  charges or levies that arise
from any  payment  made  hereunder  or under  the  Notes or from the  execution,
delivery or registration  of,  performance  under, or otherwise with respect to,
this Agreement,  the Letters of Credit or the Notes (hereinafter  referred to as
"Other Taxes").

     (c) The Borrowers  shall indemnify each Lender Party and each Agent for and
hold them harmless against the full amount of Taxes and Other Taxes, and for the
full amount of taxes of any kind imposed by any  jurisdiction on amounts payable
under this Section  2.12,  imposed on or paid by such Lender Party or such Agent
(as the case may be) and any liability (including  penalties,  additions to tax,
interest  and  expenses)  arising  therefrom  or  with  respect  thereto.   This
indemnification  shall be made within 30 days from the date such Lender Party or
such Agent (as the case may be) makes written demand  therefor.  Any such demand
shall show in reasonable  detail the amount payable and the calculations used to
determine such amount.

                                       43
<PAGE>

     (d) Within 30 days after the date of any  payment of Taxes,  the  Borrowers
shall furnish to the Administrative Agent, at its address referred to in Section
9.02, the original or a certified copy of a receipt evidencing such payment.  In
the case of any  payment  hereunder  or under  the  Notes by or on behalf of the
Borrowers  through an account or branch  outside  the United  States or by or on
behalf of the  Borrowers by a payor that is not a United States  person,  if the
Borrowers determine that no Taxes are payable in respect thereof,  the Borrowers
shall  furnish,  or shall  cause such payor to  furnish,  to the  Administrative
Agent, at such address,  an opinion of counsel  acceptable to the Administrative
Agent  stating  that  such  payment  is  exempt  from  Taxes.  For  purposes  of
subsections  (d) and (e) of this Section  2.12,  the terms  "United  States" and
"United States person" shall have the meanings  specified in Section 7701 of the
Internal Revenue Code.

     (e) Each Lender Party  organized  under the laws of a jurisdiction  outside
the United States  shall,  on or prior to the date of its execution and delivery
of this  Agreement in the case of each  Initial  Lender Party and on the date of
the Assignment and Acceptance pursuant to which it becomes a Lender Party in the
case of each other Lender Party,  and from time to time  thereafter as requested
in writing by the  Borrowers  (but only so long  thereafter as such Lender Party
remains  lawfully able to do so), provide each of the  Administrative  Agent and
the Borrowers with two original  Internal  Revenue  Service forms 1001,  4224 or
form  W-8  (and,  if such  Lender  Party  delivers  a form  W-8,  a  certificate
representing  that such  Lender  Party is not a "bank" for  purposes  of Section
881(c) of the Internal Revenue Code, is not a 10-percent shareholder (within the
meaning of Section  871(h)(3)(B) of the Internal  Revenue Code) of the Borrowers
and is not a controlled foreign corporation related to the Borrowers (within the
meaning of Section 864(d)(4) of the Internal Revenue Code)), as appropriate,  or
any  successor  or  other  form  prescribed  by the  Internal  Revenue  Service,
certifying  that such Lender  Party is exempt from or entitled to a reduced rate
of United States  withholding tax on payments  pursuant to this Agreement or the
Notes or, in the case of a Lender Party  providing a form W-8,  certifying  that
such Lender Party is a foreign corporation, partnership, estate or trust. If the
forms  provided by a Lender Party at the time such Lender Party first  becomes a
party to this Agreement  indicate a United States interest  withholding tax rate
in excess of zero,  withholding  tax at such rate shall be  considered  excluded
from Taxes unless and until such Lender Party  provides  the  appropriate  forms
certifying that a lesser rate applies,  whereupon withholding tax at such lesser
rate only shall be considered  excluded from Taxes for periods  governed by such
forms;  provided,  however, that if, at the effective date of the Assignment and
Acceptance  pursuant to which a Lender Party becomes a party to this  Agreement,
the Lender Party assignor was entitled to payments under  subsection (a) of this
Section  2.12 in  respect  of United  States  withholding  tax with  respect  to
interest paid at such date,  then, to such extent,  the term Taxes shall include
(in  addition  to  withholding  taxes that may be imposed in the future or other
amounts  otherwise  includable in Taxes) United States  withholding tax, if any,
applicable  with respect to the Lender Party  assignee on such date. If any form
or document  referred to in this  subsection  (e)  requires  the  disclosure  of
information,  other than  information  necessary  to compute the tax payable and
information  required on the date hereof by Internal  Revenue Service form 1001,
4224 or W-8 (or the related  certificate  described above),  that the applicable
Lender Party reasonably  considers to be  confidential,  such Lender Party shall
give notice  thereof to the  Borrowers  and shall not be obligated to include in
such form or document such confidential information.

     (f) For any  period  with  respect  to which a Lender  Party has  failed to
provide the Borrowers  with the  appropriate  form  described in subsection  (e)
above (other than if such failure is due to a change in law occurring  after the
date on which a form  originally  was  required  to be  provided or if such form


                                       44
<PAGE>

otherwise is not required under  subsection (e) above),  such Lender Party shall
not be entitled to  indemnification  under subsection (a) or (c) of this Section
2.12  with  respect  to Taxes  imposed  by the  United  States by reason of such
failure;  provided,  however, that should a Lender Party become subject to Taxes
because of its failure to deliver a form required hereunder, the Borrowers shall
take such steps as such  Lender  Party shall  reasonably  request to assist such
Lender Party to recover such Taxes.

     (g) Any Lender Party claiming any additional  amounts  payable  pursuant to
this Section 2.12 agrees to use reasonable efforts (consistent with its internal
policy and legal and regulatory  restrictions) to change the jurisdiction of its
Eurodollar  Lending  Office if the making of such a change  would avoid the need
for, or reduce the amount of, any such  additional  amounts that may  thereafter
accrue and would not,  in the  reasonable  judgment  of such  Lender  Party,  be
disadvantageous to such Lender Party.

     SECTION 2.13. Sharing of Payments, Etc. If any Lender Party shall obtain at
any time any payment (whether  voluntary,  involuntary,  through the exercise of
any right of  set-off,  or  otherwise,  other than as a result of an  assignment
pursuant to Section 9.07) (a) on account of Obligations  due and payable to such
Lender Party hereunder and under the Notes at such time in excess of its ratable
share (according to the proportion of (i) the amount of such Obligations due and
payable to such Lender  Party at such time to (ii) the  aggregate  amount of the
Obligations due and payable to all Lender Parties  hereunder and under the Notes
at such time) of payments on account of the  Obligations  due and payable to all
Lender  Parties  hereunder  and under the Notes at such time obtained by all the
Lender Parties at such time or (b) on account of Obligations  owing (but not due
and payable) to such Lender Party  hereunder and under the Notes at such time in
excess of its ratable share  (according  to the  proportion of (i) the amount of
such  Obligations  owing to such Lender Party at such time to (ii) the aggregate
amount of the Obligations  owing (but not due and payable) to all Lender Parties
hereunder  and under the  Notes at such  time) of  payments  on  account  of the
Obligations  owing (but not due and payable) to all Lender Parties hereunder and
under the Notes at such time obtained by all of the Lender Parties at such time,
such Lender Party shall  forthwith  purchase from the other Lender  Parties such
interests or participating interests in the Obligations due and payable or owing
to them,  as the case may be, as shall be  necessary  to cause  such  purchasing
Lender Party to share the excess  payment  ratably with each of them;  provided,
however,  that  if all or any  portion  of such  excess  payment  is  thereafter
recovered  from such  purchasing  Lender  Party,  such  purchase from each other
Lender Party shall be  rescinded  and such other Lender Party shall repay to the
purchasing  Lender Party the purchase price to the extent of such Lender Party's
ratable  share  (according to the  proportion of (i) the purchase  price paid to
such  Lender  Party to (ii) the  aggregate  purchase  price  paid to all  Lender
Parties) of such recovery  together with an amount equal to such Lender  Party's
ratable  share  (according  to the  proportion  of (i) the  amount of such other
Lender Party's required repayment to (ii) the total amount so recovered from the
purchasing  Lender Party) of any interest or other amount paid or payable by the
purchasing  Lender  Party in  respect  of the total  amount so  recovered.  Each
Borrower agrees that any Lender Party so purchasing an interest or participating
interest  from another  Lender  Party  pursuant to this Section 2.13 may, to the
fullest extent permitted by law,  exercise all its rights of payment  (including
the right of set-off) with respect to such interest or  participating  interest,
as the case may be, as fully as if such Lender Party were the direct creditor of
such Borrower in the amount of such interest or participating  interest,  as the
case may be.

     SECTION 2.14.  Use of Proceeds.  The proceeds of the Advances and issuances
of Letters of Credit shall be available (and the Borrowers agree that they shall


                                       45
<PAGE>

use such proceeds and Letters of Credit)  solely for the  following:  (a) in the
case of the Tranche A Term Advances,  (i) to pay transaction costs in connection
with the negotiation, syndication, execution and delivery of the Loan Documents;
(ii) the purchase of certain receivables (other than Excluded  Receivables) from
ICG Telecom  Group,  Inc. and its  Subsidiaries,  subject to a maximum  purchase
price of $50,000,000,  (b) in the case of the Term Advances, to finance the cost
(including, without limitation, with respect to the cost of design, development,
acquisition   construction,   installation,   improvement,   transportation   or
integration),  to acquire  equipment,  inventory,  assets,  services and related
costs in connection  with the Internet  Service  Business or  Telecommunications
Business (including, without limitation,  acquisitions by way of acquisitions of
real property,  leasehold  improvements,  licenses,  rights-of-use,  Capitalized
Leases,  installment  sales and  acquisitions  of the capital stock of an entity
that becomes a Restricted  Subsidiary  to the extent of the fair market value of
the equipment, inventory or assets so acquired (but excluding goodwill)) and (c)
in the case of the Working Capital Facility, for working capital purposes.

     SECTION 2.15.  Defaulting Lenders.  (a) In the event that, at any one time,
(i) any Lender Party shall be a Defaulting  Lender,  (ii) such Defaulting Lender
shall owe a  Defaulted  Advance  to the  Appropriate  Borrower  and  (iii)  such
Borrower shall be required to make any payment hereunder or under any other Loan
Document to or for the account of such  Defaulting  Lender,  then such  Borrower
may, so long as no Default  shall occur or be continuing at such time and to the
fullest  extent  permitted by applicable  law, set off and  otherwise  apply the
Obligation  of it to make such payment to or for the account of such  Defaulting
Lender against the obligation of such  Defaulting  Lender to make such Defaulted
Advance.  In the event that, on any date, the Appropriate  Borrower shall so set
off and  otherwise  apply its  obligation  to make any such payment  against the
obligation of such  Defaulting  Lender to make any such Defaulted  Advance on or
prior to such date, the amount so set off and otherwise applied by such Borrower
shall constitute for all purposes of this Agreement and the other Loan Documents
an Advance  by such  Defaulting  Lender  made on the date of such  setoff.  Such
Advance shall be  considered,  for all purposes of this  Agreement,  to comprise
part of the  Borrowing  in  connection  with which such  Defaulted  Advance  was
originally  required  to have been made  pursuant to Section  2.01,  even if the
other Advances  comprising  such Borrowing  shall be Eurodollar Rate Advances on
the date such Advance is deemed to be made pursuant to this  subsection (a). The
Appropriate  Borrower  shall  notify the  Administrative  Agent at any time such
Borrower  exercises  its right of set-off  pursuant to this  subsection  (a) and
shall set forth in such  notice  (A) the name of the  Defaulting  Lender and the
Defaulted  Advance  required  to be made by such  Defaulting  Lender and (B) the
amount  set off and  otherwise  applied in  respect  of such  Defaulted  Advance
pursuant to this subsection (a). Any portion of such payment otherwise  required
to be made by the Appropriate  Borrower to or for the account of such Defaulting
Lender which is paid by such Borrower, after giving effect to the amount set off
and otherwise applied by such Borrower pursuant to this subsection (a), shall be
applied by the  Administrative  Agent as specified in  subsection  (b) or (c) of
this Section 2.15.

     (b) In the event  that,  at any one time,  (i) any Lender  Party shall be a
Defaulting  Lender,  (ii) such Defaulting Lender shall owe a Defaulted Amount to
any Agent or any of the other Lender Parties and (iii) the Borrowers  shall make
any payment  hereunder  or under any other Loan  Document to the  Administrative
Agent for the account of such Defaulting Lender,  then the Administrative  Agent
may,  on its  behalf or on  behalf of such  other  Agents or such  other  Lender
Parties and to the fullest  extent  permitted by applicable  law,  apply at such
time the amount so paid by any of such  Borrowers  to or for the account of such
Defaulting  Lender to the  payment of each such  Defaulted  Amount to the extent
required  to pay such  Defaulted  Amount.  In the event that the  Administrative


                                       46
<PAGE>

Agent shall so apply any such amount to the payment of any such Defaulted Amount
on any date, the amount so applied by the Administrative  Agent shall constitute
for all purposes of this Agreement and the other Loan Documents payment, to such
extent, of such Defaulted Amount on such date. Any such amount so applied by the
Administrative   Agent  shall  be  retained  by  the  Administrative   Agent  or
distributed  by the  Administrative  Agent to such  other  Agents or such  other
Lender  Parties,  ratably in  accordance  with the  respective  portions of such
Defaulted Amounts payable at such time to the  Administrative  Agent, such other
Agents and such other Lender  Parties and, if the amount of such payment made by
the Borrowers shall at such time be  insufficient  to pay all Defaulted  Amounts
owing at such time to the Administrative Agent, such other Agents and such other
Lender Parties, in the following order of priority:

          (i) first,  to the Agents for any Defaulted  Amounts then owing to the
     Agents,  ratably in accordance with such respective  Defaulted Amounts then
     owing to the Agents; and

          (ii) second,  to any other Lender  Parties for any  Defaulted  Amounts
     then owing to such other Lender  Parties,  ratably in accordance  with such
     respective Defaulted Amounts then owing to such other Lender Parties.

Any  portion  of such  amount  paid by the  Borrowers  for the  account  of such
Defaulting  Lender  remaining,  after giving effect to the amount applied by the
Administrative  Agent pursuant to this  subsection  (b), shall be applied by the
Administrative Agent as specified in subsection (c) of this Section 2.15.

     (c) In the event  that,  at any one time,  (i) any Lender  Party shall be a
Defaulting Lender, (ii) such Defaulting Lender shall not owe a Defaulted Advance
or a Defaulted  Amount and (iii) the  Borrowers,  any Agent or any other  Lender
Party shall be required to pay or distribute  any amount  hereunder or under any
other Loan Document to or for the account of such  Defaulting  Lender,  then the
Borrowers  or such Agent or such other Lender Party shall pay such amount to the
Administrative  Agent to be held by the  Administrative  Agent,  to the  fullest
extent permitted by applicable law, in escrow or the Administrative Agent shall,
to the fullest  extent  permitted by applicable  law, hold in escrow such amount
otherwise held by it. Any funds held by the Administrative Agent in escrow under
this  subsection  (c) shall be  deposited  by the  Administrative  Agent in such
account as the Administrative  Agent shall designate in writing to the Borrowers
and  the  Defaulting   Lender,  in  the  name  and  under  the  control  of  the
Administrative  Agent, but subject to the provisions of this subsection (c). The
terms  applicable to such account,  including the rate of interest  payable with
respect to the credit  balance of such account  from time to time,  shall be the
Administrative  Agent's standard terms applicable to escrow accounts  maintained
with it. Any  interest  credited to such account from time to time shall be held
by the  Administrative  Agent in escrow under, and applied by the Administrative
Agent from time to time in accordance  with the provisions  of, this  subsection
(c).  The  Administrative  Agent  shall,  to the  fullest  extent  permitted  by
applicable  law,  apply  all  funds so held in  escrow  from time to time to the
extent  necessary  to make any Advances  required to be made by such  Defaulting
Lender and to pay any amount  payable by such  Defaulting  Lender  hereunder and
under the other Loan Documents to the  Administrative  Agent or any other Lender
Party, as and when such Advances or amounts are required to be made or paid and,
if the amount so held in escrow  shall at any time be  insufficient  to make and
pay all such  Advances and amounts  required to be made or paid at such time, in
the following order of priority:


                                       47
<PAGE>

          (i) first,  to the Agents for any amounts then due and payable by such
     Defaulting Lender to the Agents hereunder,  ratably in accordance with such
     amounts then due and payable to the Agents;

          (ii) second,  to any other Lender  Parties for any amount then due and
     payable by such Defaulting  Lender to such other Lender Parties  hereunder,
     ratably in accordance with such respective  amounts then due and payable to
     such other Lender Parties; and

          (iii) third, to the Borrowers for any Advance then required to be made
     by such  Defaulting  Lender  pursuant to a  Commitment  of such  Defaulting
     Lender.

In the event that any Lender Party that is a  Defaulting  Lender  shall,  at any
time,  cease to be a  Defaulting  Lender,  any funds held by the  Administrative
Agent in  escrow  at such  time  with  respect  to such  Lender  Party  shall be
distributed by the Administrative Agent to such Lender Party and applied by such
Lender  Party to the  Obligations  owing to such Lender Party at such time under
this  Agreement  and the other Loan  Documents  ratably in  accordance  with the
respective amounts of such Obligations outstanding at such time.

     (d) The rights and remedies against a Defaulting  Lender under this Section
2.15 are in addition to other rights and remedies  that the  Borrowers  may have
against such  Defaulting  Lender with respect to any Defaulted  Advance and that
any Agent or any Lender  Party may have  against  such  Defaulting  Lender  with
respect to any Defaulted Amount.

     (e) Notwithstanding anything in this Section 2.15 to the contrary, upon any
payment by the  Borrowers  hereunder or under any other Loan  Documents  for the
account of a Defaulting  Lender,  the  Administrative  Agent and the  Defaulting
Lender  shall treat such  payment as having been  applied in the manner in which
the Borrower  intended for purposes of calculating  interest or commitment  fees
owed by the Borrowers.

     areas  within its and each of its  Subsidiaries'  business  and  operations
     (including  those affected by suppliers,  vendors and customers) that could

     basis to be able to perform properly date-sensitive functions for all dates
     before and after  January 1, 2000  ("Year 2000  Compliant"),  except to the
     extent that a failure to do so could not  reasonably  be expected to have a

          (b) any  representation  or warranty made by any Loan Party (or any of
     its officers)  under or in connection with any Loan Document shall prove to

     continue  after the  applicable  grace  period,  if any,  specified  in the
     agreement  or  instrument  relating to such Debt;  or any other event shall
     occur or condition  shall exist under any agreement or instrument  relating
     to any such Debt and shall continue after the applicable  grace period,  if
     any, specified in such agreement or instrument, if the effect of such event

provided, however, that if, at the end of any such period (a "Base Quarter") set
forth above, the amount specified above for such Base Quarter exceeds the amount


                                       84
<PAGE>

of  Capital  Expenditures  made by ICG and its  Subsidiaries  during  such  Base
Quarter  (the amount of such  excess  being the  "Excess  Amount"),  ICG and its
Subsidiaries shall be entitled to make additional Capital Expenditures in either
of the two succeeding periods set forth above in an amount in the aggregate over
such succeeding periods equal to the Excess Amount;

then, and in any such event, the Administrative  Agent (i) shall at the request,
or may with the consent,  of the Required  Lenders,  by notice to the Borrowers,
declare the  Commitments  of each Lender Party and the obligation of each Lender
Party to make Advances (other than Letter of Credit Advances by the Issuing Bank
or a Working Capital Lender pursuant to Section 2.03(c)) and of the Issuing Bank
to issue Letters of Credit to be terminated,  whereupon the same shall forthwith
terminate,  and (ii)  shall at the  request,  or may  with the  consent,  of the
Required  Lenders,  (A) by notice  to the  Borrowers,  declare  the  Notes,  all
interest  thereon and all other  amounts  payable  under this  Agreement and the
other Loan Documents to be forthwith due and payable,  whereupon the Notes,  all
such  interest  and all such  amounts  shall  become  and be  forthwith  due and
payable, without presentment, demand, protest or further notice of any kind, all
of which are hereby  expressly  waived by the  Borrowers,  (B) by notice to each
party  required  under the terms of any  agreement in support of which a Standby
Letter of Credit is issued, request that all Obligations under such agreement be
declared to be due and payable and (C) by notice to the Issuing Bank, direct the
Issuing Bank to deliver a Default  Termination Notice to the beneficiary of each
Standby  Letter of Credit  issued by it, and the Issuing Bank shall deliver such
Default Termination Notices;  provided,  however, that in the event of an actual
or deemed entry of an order for relief with respect to the  Borrowers  under the
Federal  Bankruptcy  Code,  (x) the  Commitments  of each  Lender  Party and the
obligation  of each Lender Party to make  Advances  (other than Letter of Credit
Advances by the Issuing  Bank or a Working  Capital  Lender  pursuant to Section
2.03(c)) and of the Issuing Bank to issue Letters of Credit shall  automatically
be  terminated  and (y) the Notes,  all such interest and all such amounts shall
automatically  become  and be due  and  payable,  without  presentment,  demand,
protest or any notice of any kind, all of which are hereby  expressly  waived by
the Borrowers.

     SECTION 6.02. Actions in Respect of the Letters of Credit upon Default.  If
any Event of Default shall have occurred and be continuing,  the  Administrative
Agent may,  or shall at the request of the  Required  Lenders,  irrespective  of
whether it is taking any of the actions  described in Section 6.01 or otherwise,
make demand upon the Borrowers to, and forthwith  upon such demand the Borrowers
will,  pay to the  Collateral  Agent on behalf of the Lender Parties in same day
funds at the Collateral Agent's office designated in such demand, for deposit in
the L/C Cash  Collateral  Account,  an amount equal to the  aggregate  Available
Amount  of  all  Letters  of  Credit  then  outstanding.  If  at  any  time  the
Administrative  Agent or the Collateral  Agent determines that any funds held in
the L/C Cash Collateral  Account are subject to any right or claim of any Person
other than the Agents  and the Lender  Parties or that the total  amount of such
funds is less than the aggregate  Available Amount of all Letters of Credit, the
Borrowers  will,  forthwith  upon  demand  by the  Administrative  Agent  or the
Collateral  Agent,  pay to the  Collateral  Agent,  as  additional  funds  to be
deposited and held in the L/C Cash  Collateral  Account,  an amount equal to the
excess of (a) such  aggregate  Available  Amount  over (b) the  total  amount of
funds,  if  any,  then  held  in  the  L/C  Cash  Collateral  Account  that  the
Administrative  Agent or the Collateral Agent, as the case may be, determines to
be free and clear of any such right and claim. Upon the drawing of any Letter of
Credit for which funds are on deposit in the L/C Cash Collateral  Account,  such
funds shall be applied to reimburse the Issuing Bank or Working Capital Lenders,
as applicable, to the extent permitted by applicable law.

                                   ARTICLE VII

                                 PARENT GUARANTY

     SECTION 7.01. Guaranty.  The Parent hereby  unconditionally and irrevocably
guarantees  the  punctual  payment  when due,  whether  at stated  maturity,  by
acceleration  or otherwise,  of all  Obligations of each other Loan Party now or
hereafter  existing under the Loan Documents,  whether for principal,  interest,
fees,   expenses  or  otherwise   (such   Obligations   being  the   "Guaranteed
Obligations"),  and  agrees to pay any and all  expenses  (including  reasonable
counsel fees and expenses)  incurred by the  Administrative  Agent or the Lender
Parties in  enforcing  any rights  under this  Guaranty.  Without  limiting  the
generality of the foregoing,  the Parent0s liability shall extend to all amounts
that  constitute  part of the Guaranteed  Obligations  and would be owed by each
such Loan Party to the Agent or any Lender  Party under the Loan  Documents  but
for the fact that they are  unenforceable  or not allowable due to the existence
of a bankruptcy, reorganization or similar proceeding involving any Loan Party.

     SECTION 7.02. Guaranty Absolute.  The Parent guarantees that the Guaranteed
Obligations  will be paid  strictly  in  accordance  with the  terms of the Loan
Documents, regardless of any law, regulation or order now or hereafter in effect
in any  jurisdiction  affecting any of such terms or the rights of the Agents or
the Lenders  with  respect  thereto.  The  Obligations  of the Parent under this
Guaranty are independent of the Guaranteed  Obligations or any other Obligations
of any Loan Party under the Loan Documents, and a separate action or actions may
be  brought  and  prosecuted  against  the  Parent  to  enforce  this  Guaranty,
irrespective  of whether  any action is brought  against any other Loan Party or
whether  any  other  Loan  Party is joined in any such  action or  actions.  The
liability of the Parent under this Guaranty shall be  irrevocable,  absolute and
unconditional  irrespective  of, and the Parent  hereby  irrevocably  waives any
defenses it may now or  hereinafter  have in any way  relating to, any or all of
the following:

          (a) any lack of validity or enforceability of any Loan Document or any
     agreement or instrument relating thereto;

          (b) any change in the time,  manner or place of payment  of, or in any
     other  term  of,  all or any of the  Guaranteed  Obligations  or any  other
     Obligations of any other Loan Party under the Loan Documents,  or any other
     amendment or waiver of or any consent to departure  from any Loan Document,
     including,  without limitation,  any increase in the Guaranteed Obligations
     resulting  from the  extension  of  additional  credit to the  Borrower  or
     otherwise;

          (c) any taking, exchange, release or non-perfection of any collateral,
     or any taking,  release or  amendment  or waiver of or consent to departure
     from any other guaranty, for all or any of the Guaranteed Obligations;

          (d) any manner of application of collateral,  or proceeds thereof,  to
     all or any of the  Guaranteed  Obligations,  or any manner of sale or other
     disposition of any collateral for all or any of the Guaranteed  Obligations
     or any other  Obligations  of any other Loan Party under the Loan Documents
     or any other assets of any Loan Party or any of their Subsidiaries;

          (e)  any  change,   restructuring  or  termination  of  the  corporate
     structure or existence of any Loan Party or any of their Subsidiaries; or


                                       86
<PAGE>

          (f) any other circumstance (including, without limitation, any statute
     of  limitations) or any existence of or reliance on any  representation  by
     the  Administrative   Agent  or  any  Lender  Party  that  might  otherwise
     constitute a defense  available to, or a discharge  of, the  Borrower,  any
     Subsidiary Guarantor or any other guarantor or surety.

     This Guaranty shall continue to be effective or be reinstated,  as the case
may be,  if at any time any  payment  of any of the  Guaranteed  Obligations  is
rescinded  or must  otherwise  be  returned by the  Administrative  Agent or any
Lender Party upon the insolvency, bankruptcy or reorganization of any Loan Party
or any of their  Subsidiaries  or otherwise,  all as though such payment had not
been made.

     SECTION  7.03.  Waiver.  The Parent hereby  waives  promptness,  diligence,
notice of acceptance  and any other notice with respect to any of the Guaranteed
Obligations and this Guaranty and any requirement that the Administrative  Agent
or any Lender Party protect,  secure, perfect or insure any Lien or any property
subject  thereto or exhaust any right or take any action  against any Loan Party
or any other  Person or any  collateral.  The Parent  acknowledges  that it will
receive   direct  and  indirect   benefits  from  the   financing   arrangements
contemplated by the Loan Documents and that the waiver set forth in this Section
7.03 is knowingly made in contemplation of such benefits

     SECTION 7.04. Subrogation.  The Parent will not exercise any rights that it
may now or hereafter acquire against the Borrower,  any Subsidiary  Guarantor or
any other  guarantor  that arise from the  existence,  payment,  performance  or
enforcement of the Parent0s  Obligations  under this Agreement or any other Loan
Document,   including,   without   limitation,   any   right   of   subrogation,
reimbursement,  exoneration,  contribution or  indemnification  and any right to
participate  in any claim or remedy of the  Administrative  Agent or any  Lender
Party against the Borrower,  any Subsidiary  Guarantor or any other guarantor or
any collateral,  whether or not such claim,  remedy or right arises in equity or
under contract, statute or common law, including,  without limitation, the right
to take or receive  from the  Borrower,  any  Subsidiary  Guarantor or any other
guarantor, directly or indirectly, in cash or other property or by set-off or in
any other manner, payment or security on account of such claim, remedy or right,
unless and until all of the Obligations and all other amounts payable under this
Guaranty  shall  have been paid in full in cash and the  Commitments  shall have
expired or terminated. If any amount shall be paid to the Parent in violation of
the preceding sentence at any time prior to the later of (i) the payment in full
in cash of the Guaranteed  Obligations  and all other amounts payable under this
Guaranty,  and (ii) the later of the Tranche A Termination  Date,  the Tranche B
Termination Date and the Working Capital  Termination Date, such amount shall be
held in trust for the benefit of the Administrative Agent and the Lender Parties
and shall  forthwith  be paid to the  Administrative  Agent to be  credited  and
applied to the Guaranteed  Obligations  and all other amounts payable under this
Guaranty, whether matured or unmatured, in accordance with the terms of the Loan
Documents,  or to be held as collateral for any Guaranteed  Obligations or other
amounts payable under this Guaranty  thereafter arising. If (i) the Parent shall
make payment to the Administrative  Agent or any Lender Party of all or any part
of the Guaranteed  Obligations,  (ii) all of the Guaranteed  Obligations and all
other  amounts  payable  under this  Guaranty  shall be paid in full in cash and
(iii) each of the Tranche A Termination Date, the Tranche B Termination Date and
the Working Capital  Termination  Date shall have occurred,  the  Administrative
Agent and the Lender Parties will, at the Parent0s request and expense,  execute
and deliver to the Parent  appropriate  documents,  without recourse and without
representation or warranty, necessary to evidence the transfer by subrogation to
the Parent of an  interest in the  Guaranteed  Obligations  resulting  from such
payment by the Parent.

                                  ARTICLE VIII

                                   THE AGENTS

     SECTION  8.01.   Authorization  and  Action.  Each  Lender  Party  (in  its
capacities as a Lender, Issuing Bank (if applicable) and on behalf of itself and
its Affiliates as potential  Hedge Banks) hereby  appoints and  authorizes  each
Agent to take such action as agent on its behalf and to exercise such powers and
discretion under this Agreement and the other Loan Documents as are delegated to
such  Agent by the terms  hereof  and  thereof,  together  with such  powers and
discretion as are reasonably incidental thereto. As to any matters not expressly
provided for by the Loan Documents (including,  without limitation,  enforcement
or  collection  of the  Notes),  no Agent  shall be  required  to  exercise  any
discretion  or take any action,  but shall be required to act or to refrain from
acting (and shall be fully  protected  in so acting or  refraining  from acting)
upon the instructions of the Required Lenders,  and such  instructions  shall be
binding  upon all Lender  Parties and all holders of Notes;  provided,  however,
that no Agent shall be required  to take any action that  exposes  such Agent to
personal liability or that is contrary to this Agreement or applicable law. Each
Agent agrees to give to each Lender Party prompt  notice of each notice given to
it by any Borrower pursuant to the terms of this Agreement.

     SECTION 8.02.  Agents'  Reliance,  Etc.  Neither any Agent nor any of their
respective  directors,  officers,  agents or  employees  shall be liable for any
action  taken or omitted to be taken by it or them under or in  connection  with
the Loan  Documents,  except  for its or their own gross  negligence  or willful
misconduct.  Without limitation of the generality of the foregoing,  each Agent:
(a) may treat the payee of any Note as the holder thereof until,  in the case of
the  Administrative  Agent,  the  Administrative  Agent  receives and accepts an
Assignment and  Acceptance  entered into by the Lender that is the payee of such
Note, as assignor, and an Eligible Assignee, as assignee, or, in the case of any
other Agent, such Agent has received notice from the  Administrative  Agent that
it has received and accepted such  Assignment  and  Acceptance,  in each case as
provided in Section 9.07; (b) may consult with legal counsel  (including counsel
for any Loan Party),  independent  public accountants and other experts selected
by it and shall not be liable  for any  action  taken or  omitted to be taken in
good faith by it in accordance  with the advice of such counsel,  accountants or
experts;  (c) makes no warranty or  representation to any Lender Party and shall
not be  responsible  to any  Lender  Party  for any  statements,  warranties  or
representations (whether written or oral) made in or in connection with the Loan
Documents;  (d) shall not have any duty to  ascertain  or to  inquire  as to the
performance  or observance  of any of the terms,  covenants or conditions of any
Loan  Document  on the  part  of any  Loan  Party  or to  inspect  the  property
(including  the  books  and  records)  of  any  Loan  Party;  (e)  shall  not be
responsible  to any  Lender  Party for the due  execution,  legality,  validity,
enforceability,  genuineness,  sufficiency  or value  of, or the  perfection  or
priority of any lien or security  interest  created or  purported  to be created
under or in  connection  with,  any Loan  Document  or any other  instrument  or
document furnished  pursuant thereto;  and (f) shall incur no liability under or
in respect of any Loan Document by acting upon any notice, consent,  certificate
or other  instrument  or writing  (which may be by telegram,  telecopy or telex)
believed by it to be genuine and signed or sent by the proper party or parties.

     SECTION 8.03. Agents and Affiliates.  With respect to its Commitments,  the
Advances  made by it and the Notes  issued to it, each Agent shall have the same
rights and powers  under the Loan  Documents  as any other  Lender Party and may


                                       88
<PAGE>

exercise the same as though it were not an Agent; and the term "Lender Party" or
"Lender Parties" shall, unless otherwise expressly indicated, include each Agent
in its individual capacity.  Each Agent and its respective affiliates may accept
deposits  from,  lend money to,  act as  trustee  under  indentures  of,  accept
investment banking engagements from and generally engage in any kind of business
with,  any  Loan  Party,  any of its  Subsidiaries  and any  Person  that may do
business with or own securities of any Loan Party or any such Subsidiary, all as
if such Agent was not an Agent and without  any duty to account  therefor to the
Lender Parties.

     SECTION 8.04. Lender Party Credit Decision.  Each Lender Party acknowledges
that it has,  independently  and  without  reliance  upon any Agent or any other
Lender Party and based on the financial  statements  referred to in Section 4.01
and such other documents and information as it has deemed appropriate,  made its
own credit analysis and decision to enter into this Agreement. Each Lender Party
also  acknowledges  that it will,  independently  and without  reliance upon any
Agent or any other Lender Party and based on such  documents and  information as
it shall deem appropriate at the time, continue to make its own credit decisions
in taking or not taking action under this Agreement.

     SECTION 8.05.  Indemnification.  (a) Each Lender Party severally  agrees to
indemnify  each Agent (to the extent not promptly  reimbursed  by the  Borrower)
from and against  such Lender  Party's  ratable  share  (determined  as provided
below) of any and all  liabilities,  obligations,  losses,  damages,  penalties,
actions,  judgments,  suits,  costs,  expenses or  disbursements  of any kind or
nature  whatsoever that may be imposed on, incurred by, or asserted against such
Agent in any way relating to or arising out of the Loan  Documents or any action
taken or omitted by such Agent under the Loan Documents; provided, however, that
no  Lender  Party  shall  be  liable  for  any  portion  of  such   liabilities,
obligations,  losses,  damages,  penalties,  actions,  judgments,  suits, costs,
expenses or  disbursements  resulting  from such  Agent's  gross  negligence  or
willful  misconduct as found in a final,  non-appealable  judgment by a court of
competent jurisdiction.  Without limitation of the foregoing,  each Lender Party
agrees to reimburse each Agent promptly upon demand for its ratable share of any
costs and expenses (including, without limitation, fees and expenses of counsel)
payable by the  Borrowers  under  Section 9.04, to the extent that such Agent is
not promptly reimbursed for such costs and expenses by the Borrowers.

     (b) Each Lender Party  severally  agrees to indemnify  the Issuing Bank (to
the extent not promptly reimbursed by the Borrower) from and against such Lender
Party's ratable share (determined as provided below) of any and all liabilities,
obligations,  losses,  damages,  penalties,  actions,  judgments,  suits, costs,
expenses or disbursements  of any kind or nature  whatsoever that may be imposed
on, incurred by, or asserted  against the Issuing Bank in any way relating to or
arising out of the Loan  Documents or any action taken or omitted by the Issuing
Bank under the Loan Documents;  provided, however, that no Lender Party shall be
liable  for any  portion  of such  liabilities,  obligations,  losses,  damages,
penalties, actions, judgments, suits, costs, expenses or disbursements resulting
from the Issuing  Bank's gross  negligence  or willful  misconduct as found in a
final,  non-appealable  judgment by a court of competent  jurisdiction.  Without
limitation of the  foregoing,  each Lender Party agrees to reimburse the Issuing
Bank  promptly  upon  demand  for its  ratable  share of any costs and  expenses
(including,  without  limitation,  fees and expenses of counsel)  payable by the
Borrowers  under  Section  9.04,  to the  extent  that the  Issuing  Bank is not
promptly reimbursed for such costs and expenses by the Borrowers.

     (c) For  purposes of this  Section  8.05,  the Lender  Parties'  respective
ratable shares of any amount shall be determined,  at any time, according to the


                                       89
<PAGE>

sum of (i) the aggregate  principal  amount of the Advances  outstanding at such
time and owing to the respective Lender Parties,  (ii) their respective Pro Rata
Shares of the aggregate Available Amount of all Letters of Credit outstanding at
such  time,  (iii)  the  aggregate  unused  portions  of their  respective  Term
Commitments  at such  time and (iv)  their  respective  Unused  Working  Capital
Commitments at such time; provided that the aggregate principal amount of Letter
of Credit  Advances  owing to the Issuing Bank shall be considered to be owed to
the Working Capital Lenders ratably in accordance with their respective  Working
Capital  Commitments.  The failure of any Lender Party to reimburse any Agent or
the Issuing Bank, as the case may be, promptly upon demand for its ratable share
of any amount  required  to be paid by the  Lender  Parties to such Agent or the
Issuing Bank, as the case may be, as provided herein shall not relieve any other
Lender Party of its obligation  hereunder to reimburse such Agent or the Issuing
Bank,  as the case may be, for its ratable  share of such amount,  but no Lender
Party  shall  be  responsible  for the  failure  of any  other  Lender  Party to
reimburse  such Agent or the  Issuing  Bank,  as the case may be, for such other
Lender Party's ratable share of such amount.  Without  prejudice to the survival
of any  other  agreement  of any  Lender  Party  hereunder,  the  agreement  and
obligations  of each Lender Party  contained in this Section 8.05 shall  survive
the  payment  in full of  principal,  interest  and all  other  amounts  payable
hereunder and under the other Loan Documents.

     SECTION 8.06.  Successor Agents. Any Agent may resign at any time by giving
written  notice  thereof  to the Lender  Parties  and the  Borrowers  and may be
removed at any time with or without cause by the Required Lenders. Upon any such
resignation or removal,  the Required  Lenders shall have the right to appoint a
successor Agent, subject, so long as no Default has occurred and continuing,  to
the consent of the Borrowers,  such consent not to be unreasonably  withheld. If
no successor  Agent shall have been so appointed  by the Required  Lenders,  and
shall have accepted such appointment,  within 30 days after the retiring Agent's
giving of notice of resignation or the Required Lenders' removal of the retiring
Agent,  then the retiring Agent may, on behalf of the Lender Parties,  appoint a
successor Agent, subject, so long as no Default has occurred and continuing,  to
the consent of the  Borrowers,  such  consent not to be  unreasonably  withheld,
which shall be a commercial  bank organized  under the laws of the United States
or of any State  thereof  and having a combined  capital and surplus of at least
$250,000,000.  Upon the acceptance of any  appointment  as Agent  hereunder by a
successor  Agent and,  in the case of a  successor  Collateral  Agent,  upon the
execution and filing or recording of such  financing  statements,  or amendments
thereto,  and such  amendments or supplements  to any mortgages,  and such other
instruments  or notices,  as may be necessary or  desirable,  or as the Required
Lenders may request, in order to continue the perfection of the Liens granted or
purported to be granted by the Collateral Documents,  such successor Agent shall
succeed to and become vested with all the rights, powers, discretion, privileges
and duties of the retiring  Agent,  and the retiring  Agent shall be  discharged
from its  duties and  obligations  under the Loan  Documents.  If within 45 days
after written  notice is given of the retiring  Agent's  resignation  or removal
under this Section 8.06 no successor  Agent shall have been  appointed and shall
have accepted such  appointment,  then on such 45th day (i) the retiring Agent's
resignation  or removal shall become  effective,  (ii) the retiring  Agent shall
thereupon be discharged from its duties and obligations under the Loan Documents
and (iii) the  Required  Lenders  shall  thereafter  perform  all  duties of the
retiring Agent under the Loan Documents until such time, if any, as the Required
Lenders appoint a successor Agent as provided above.  After any retiring Agent's
resignation  or removal  hereunder  as Agent  shall have become  effective,  the
provisions  of this  Article  VII shall  inure to its  benefit as to any actions
taken or omitted to be taken by it while it was Agent under this Agreement.

Documents,  consented  to) by the  Required  Lenders,  and then  such  waiver or
consent  shall be effective  only in the specific  instance and for the specific
purpose for which given;  provided,  however,  that (a) no amendment,  waiver or
consent  shall,  unless in writing and signed by all of the Lenders  (other than
any Lender  Party that is, at such time,  a  Defaulting  Lender),  do any of the

Subsidiary Guaranty), (iv) release any material portion of the Collateral in any
transaction  or  series  of  related   transactions   or  permit  the  creation,
incurrence,  assumption or existence of any Lien on any material  portion of the

Obligations  other than Obligations  owing to the Secured Parties under the Loan
Documents,  (v) amend  Section  2.13 or this  Section  9.01,  (vi)  increase the

payable  hereunder,  or (ix) limit the  liability of any Loan Party under any of
the Loan  Documents and (b) no  amendment,  waiver or consent  shall,  unless in
writing  and signed by the  Required  Lenders  and each  Lender  (other than any
Lender that is, at such time, a Defaulting  Lender) that has a Commitment  under
the Term  Facilities  or Working  Capital  Facility  if such  Lender is directly
affected by such amendment,  waiver or consent,  (i) increase the Commitments of
such  Lender,  (ii) reduce the  principal  of, or interest on, the Notes held by
such Lender or any fees or other amounts payable hereunder to such Lender, (iii)

Issuing Bank, as the case may be, in addition to the Lenders  required  above to
take such  action,  affect the rights or  obligations  of the Issuing Bank under
this Agreement; and provided further that no amendment, waiver or consent shall,
unless in writing and signed by an Agent in  addition  to the  Lenders  required
above to take such action,  affect the rights or duties of such Agent under this
Agreement or the other Loan Documents.

     SECTION  9.03.  No Waiver;  Remedies.  No failure on the part of any Lender
Party or any Agent to exercise, and no delay in exercising,  any right hereunder

thereof or the exercise of any other right.  The  remedies  herein  provided are
cumulative and not exclusive of any remedies provided by law.

     SECTION  9.04.  Costs and  Expenses.  (a) Subject to the  provisions of the
Commitment  Letter,  the Borrowers  agree jointly and severally to pay on demand
(i) all costs and expenses of the Administrative  Agent and the Collateral Agent
in  connection  with  the  preparation,   execution,  delivery,  administration,
modification and amendment of the Loan Documents (including, without limitation,
(A) all due diligence, collateral review, syndication, transportation, computer,
duplication,   appraisal,  audit,  insurance,  consultant,  search,  filing  and
recording fees and expenses and (B) the reasonable  fees and expenses of counsel

Subsidiaries  arising out of any Default or any events or circumstances that may
give rise to a Default and with  respect to  presenting  claims in or  otherwise
participating  in or  monitoring  any  bankruptcy,  insolvency  or other similar
proceeding  involving  creditors' rights generally and any proceeding  ancillary

affecting  creditors'  rights  generally  (including,  without  limitation,  the
reasonable  fees and  expenses of counsel for the  Administrative  Agent and the
Collateral Agent and each Lender Party with respect thereto).

     (b) The Borrowers agree to indemnify, defend and save and hold harmless the
Administrative  Agent and the  Collateral  Agent,  each Lender Party and each of
their Affiliates and their respective officers, directors, employees, agents and
advisors  (each,  an  "Indemnified  Party") from and  against,  and shall pay on
demand,  any  and  all  claims,  damages,   losses,   liabilities  and  expenses
(including,  without  limitation,  reasonable fees and expenses of counsel) that
may be incurred by or asserted or awarded against any Indemnified Party, in each
case arising out of or in connection  with or by reason of  (including,  without
limitation,  in connection with any  investigation,  litigation or proceeding or
preparation of a defense in connection therewith) (i) the Facilities, the actual


                                       92
<PAGE>

or proposed use of the  proceeds of the  Advances or the Letters of Credit,  the
Transaction  Documents or any of the transactions  contemplated thereby, or (ii)
the actual or alleged  presence of  Hazardous  Materials  on any property of any
Loan Party or any of its  Subsidiaries or any  Environmental  Action relating in
any way to any Loan Party or any of its Subsidiaries,  except to the extent such
claim, damage,  loss,  liability or expense is found in a final,  non-appealable
judgment  by a court  of  competent  jurisdiction  to have  resulted  from  such
Indemnified  Party's gross negligence or willful  misconduct.  In the case of an
investigation,  litigation  or other  proceeding  to which the indemnity in this
Section 9.04(b) applies,  such indemnity shall be effective  whether or not such
investigation,  litigation  or  proceeding  is  brought by any Loan  Party,  its
directors, shareholders or creditors or an Indemnified Party, whether or not any
Indemnified  Party  is  otherwise  a  party  thereto  and  whether  or  not  the
Transaction  is  consummated.  Each Borrower also agrees not to assert any claim
against any Agent, any Lender Party or any of their Affiliates,  or any of their
respective officers, directors, employees, agents and advisors, on any theory of
liability, for special, indirect,  consequential or punitive damages arising out
of or otherwise  relating to the  Facilities,  the actual or proposed use of the
proceeds of the Advances or the Letters of Credit, the Transaction  Documents or
any of the transactions contemplated by the Transaction Documents.

     (c) If any payment of principal of, or Conversion of, any  Eurodollar  Rate
Advance is made by any  Borrower to or for the  account of a Lender  Party other
than on the last day of the Interest  Period for such Advance,  as a result of a
payment  or  Conversion  pursuant  to  Section  2.06,   2.09(b)(i)  or  2.10(d),
acceleration  of the  maturity of the Notes  pursuant to Section 6.01 or for any
other  reason,  or by an Eligible  Assignee to a Lender  Party other than on the
last day of the Interest  Period for such Advance upon an  assignment  of rights
and obligations  under this Agreement  pursuant to Section 9.07 as a result of a
demand by the Borrowers pursuant to Section 9.07(a), or if the Borrowers fail to
make any payment or  prepayment  of an Advance for which a notice of  prepayment
has been given or that is  otherwise  required to be made,  whether  pursuant to
Section 2.04,  2.06 or 6.01 or otherwise,  the Borrowers  shall,  upon demand by
such  Lender  Party (with a copy of such  demand to the  Administrative  Agent),
jointly and  severally pay to the  Administrative  Agent for the account of such
Lender  Party any amounts  required  to  compensate  such  Lender  Party for any
additional losses, costs or expenses that it may reasonably incur as a result of
such payment or Conversion or such failure to pay or prepay, as the case may be,
including, without limitation, any loss (including loss of anticipated profits),
cost or  expense  incurred  by  reason of the  liquidation  or  reemployment  of
deposits or other funds  acquired by any Lender  Party to fund or maintain  such
Advance.

     (d) If any Loan Party  fails to pay when due any costs,  expenses  or other
amounts payable by it under any Loan Document,  including,  without  limitation,
fees and expenses of counsel and indemnities,  such amount may be paid on behalf
of such Loan Party by the Administrative  Agent or any Lender Party, in its sole
discretion.

     (e) Without  prejudice to the  survival of any other  agreement of any Loan
Party hereunder or under any other Loan Document, the agreements and obligations
of each Borrower contained in Sections 2.10 and 2.12 and this Section 9.04 shall
survive the payment in full of principal, interest and all other amounts payable
hereunder and under any of the other Loan Documents.

     SECTION  9.05.  Right of Set-off.  Upon (a) the  occurrence  and during the
continuance  of any Event of Default  and (b) the  making of the  request or the
granting  of  the  consent   specified  by  Section   6.01  to   authorize   the


                                       93
<PAGE>

Administrative  Agent to  declare  the Notes  due and  payable  pursuant  to the
provisions of Section  6.01,  each Agent and each Lender Party and each of their
respective Affiliates is hereby authorized at any time and from time to time, to
the fullest extent  permitted by law, to set off and otherwise apply any and all
deposits (general or special, time or demand,  provisional or final) at any time
held and other  indebtedness at any time owing by such Agent,  such Lender Party
or such  Affiliate to or for the credit or the account of each Borrower  against
any and all of the Obligations of such Borrower now or hereafter  existing under
the Loan  Documents,  irrespective  of whether  such Agent or such Lender  Party
shall  have  made any  demand  under  this  Agreement  or such Note or Notes and
although such  Obligations  may be  unmatured.  Each Agent and each Lender Party
agrees promptly to notify each Borrower after any such set-off and  application;
provided,  however,  that the failure to give such  notice  shall not affect the
validity  of such  set-off  and  application.  The rights of each Agent and each
Lender Party and their respective  Affiliates under this Section are in addition
to other rights and remedies  (including,  without  limitation,  other rights of
set-off) that such Agent, such Lender Party and their respective  Affiliates may
have.

     SECTION 9.06. Binding Effect. This Agreement shall become effective when it
shall have been  executed by the Borrower and each Agent and the  Administrative
Agent shall have been  notified by each  Initial  Lender Party that such Initial
Lender Party has executed it and  thereafter  shall be binding upon and inure to
the  benefit  of each  Borrower,  each  Agent  and each  Lender  Party and their
respective successors and assigns,  except that the Borrowers shall not have the
right to assign their rights  hereunder or any interest herein without the prior
written consent of the Lender Parties.

     SECTION 9.07.  Assignments and Participations.  (a) Each Lender may and, so
long as no Default  shall have  occurred and be  continuing,  if demanded by the
Borrowers  (following a demand by such Lender  pursuant to Section 2.10 or 2.12)
upon at least five Business  Days' notice to such Lender and the  Administrative
Agent,  will assign to one or more  Eligible  Assignees  all or a portion of its
rights and obligations under this Agreement (including,  without limitation, all
or a portion of its Commitment or Commitments,  the Advances owing to it and the
Note or Notes  held by it);  provided,  however,  that (i) each such  assignment
shall  be of a  uniform,  and  not a  varying,  percentage  of  all  rights  and
obligations  under and in respect of one or more Facilities,  (ii) except in the
case of an assignment to a Person that,  immediately  prior to such  assignment,
was a Lender, an Affiliate of any Lender or an Approved Fund of any Lender or an
assignment of all of a Lender's rights and obligations under this Agreement, the
aggregate  amount of the  Commitments  being assigned to such Eligible  Assignee
pursuant to such  assignment  (determined  as of the date of the  Assignment and
Acceptance  with  respect  to such  assignment)  shall in no event be less  than
$3,000,000  (or such lesser  amount as shall be  approved by the  Administrative
Agent and, so long as no Default  shall have  occurred and be  continuing at the
time of effectiveness of such assignment,  the Borrower) under each Facility for
which a Commitment is being assigned,  (iii) each such assignment shall be to an
Eligible Assignee, (iv) each such assignment made as a result of a demand by the
Borrower  pursuant to this  Section  9.07(a)  shall be arranged by the  Borrower
after  consultation  with  the  Administrative  Agent  and  shall be  either  an
assignment of all of the rights and  obligations  of the assigning  Lender under
this Agreement or an assignment of a portion of such rights and obligations made
concurrently  with  another  such  assignment  or other  such  assignments  that
together cover all of the rights and  obligations of the assigning  Lender under
this Agreement,  (v) no Lender shall be obligated to make any such assignment as
a result of a demand by the Borrower pursuant to this Section 9.07(a) unless and
until such  Lender  shall have  received  one or more  payments  from either the
Borrower or one or more Eligible Assignees in an aggregate amount at least equal
to the  aggregate  outstanding  principal  amount of the Advances  owing to such


                                       94
<PAGE>

Lender,  together with accrued  interest  thereon to the date of payment of such
principal  amount  and all other  amounts  payable  to such  Lender  under  this
Agreement,  (vi) no such assignments  shall be permitted  without the consent of
the Administrative  Agent until the Administrative Agent shall have notified the
Lender Parties that syndication of the Commitments  hereunder has been completed
and (vii) the parties to each such  assignment  shall execute and deliver to the
Administrative  Agent,  for its  acceptance  and recording in the  Register,  an
Assignment  and  Acceptance,  together  with any Note or Notes  subject  to such
assignment and a processing and  recordation fee of $3,000;  provided,  however,
that (A) such processing and recordation fee shall be $1,500 for any Person that
immediately  prior to such  assignment was a Lender;  (B) there shall be no such
processing and  recordation  fee for any Person that  immediately  prior to such
assignment  was an Affiliate  of such  assigning  Lender;  and (C) for each such
assignment made as a result of a demand by the Borrower pursuant to this Section
9.07(a),  the  Borrower  shall pay to the  Administrative  Agent the  applicable
processing and recordation fee.

     (b) Upon such execution, delivery, acceptance and recording, from and after
the effective date specified in such Assignment and Acceptance, (i) the assignee
thereunder  shall  be a  party  hereto  and,  to  the  extent  that  rights  and
obligations  hereunder have been assigned to it pursuant to such  Assignment and
Acceptance,  have the rights and obligations of a Lender or Issuing Bank, as the
case may be,  hereunder and (ii) the Lender or Issuing Bank assignor  thereunder
shall, to the extent that rights and obligations hereunder have been assigned by
it pursuant to such Assignment and Acceptance, relinquish its rights (other than
its rights under Sections 2.10, 2.12 and 9.04 to the extent any claim thereunder
relates to an event arising prior to such  assignment)  and be released from its
obligations  under  this  Agreement  (and,  in the  case  of an  Assignment  and
Acceptance  covering all of the  remaining  portion of an assigning  Lender's or
Issuing  Bank's  rights and  obligations  under this  Agreement,  such Lender or
Issuing Bank shall cease to be a party hereto).

     (c) By executing and delivering an Assignment and  Acceptance,  each Lender
Party assignor thereunder and each assignee thereunder confirm to and agree with
each other and the other parties  thereto and hereto as follows:  (i) other than
as provided in such Assignment and Acceptance, such assigning Lender Party makes
no representation or warranty and assumes no responsibility  with respect to any
statements, warranties or representations made in or in connection with any Loan
Document or the  execution,  legality,  validity,  enforceability,  genuineness,
sufficiency  or value of, or the  perfection or priority of any lien or security
interest  created or purported to be created  under or in connection  with,  any
Loan Document or any other instrument or document  furnished  pursuant  thereto;
(ii) such assigning Lender Party makes no representation or warranty and assumes
no responsibility  with respect to the financial  condition of any Loan Party or
the performance or observance by any Loan Party of any of its obligations  under
any Loan  Document  or any  other  instrument  or  document  furnished  pursuant
thereto;  (iii)  such  assignee  confirms  that it has  received  a copy of this
Agreement,  together  with  copies of the  financial  statements  referred to in
Section  4.01  and  such  other  documents  and  information  as it  has  deemed
appropriate  to make its own credit  analysis  and  decision  to enter into such
Assignment and Acceptance;  (iv) such assignee will,  independently  and without
reliance upon any Agent,  such assigning  Lender Party or any other Lender Party
and based on such documents and information as it shall deem  appropriate at the
time,  continue to make its own credit  decisions in taking or not taking action
under  this  Agreement;  (v)  such  assignee  confirms  that  it is an  Eligible
Assignee;  (vi) such assignee  appoints and  authorizes  each Agent to take such
action as agent on its behalf and to exercise such powers and  discretion  under
the Loan  Documents  as are  delegated  to such  Agent by the terms  hereof  and
thereof,  together with such powers and discretion as are reasonably  incidental


                                       95
<PAGE>

thereto;  and (vii) such assignee agrees that it will perform in accordance with
their  terms  all of the  obligations  that by the terms of this  Agreement  are
required to be performed by it as a Lender or Issuing Bank, as the case may be.

     (d) The  Administrative  Agent,  acting for this purpose (but only for this
purpose) as the agent of the Borrower, shall maintain at its address referred to
in  Section  9.02 a copy of each  Assignment  and  Acceptance  delivered  to and
accepted by it and a register for the  recordation of the names and addresses of
the Lender  Parties and the  Commitment  under each  Facility of, and  principal
amount of the Advances owing under each Facility to, each Lender Party from time
to time (the  "Register").  The entries in the Register  shall be conclusive and
binding for all purposes,  absent manifest error,  and the Borrower,  the Agents
and the Lender  Parties  shall treat each  Person  whose name is recorded in the
Register as a Lender Party  hereunder  for all purposes of this  Agreement.  The
Register  shall be available for  inspection by the Borrower or any Agent or any
Lender Party at any reasonable time and from time to time upon reasonable  prior
notice.

     (e) Upon  its  receipt  of an  Assignment  and  Acceptance  executed  by an
assigning Lender Party and an assignee,  together with any Note or Notes subject
to such  assignment,  the  Administrative  Agent shall,  if such  Assignment and
Acceptance  has been  completed  and is in  substantially  the form of Exhibit C
hereto,  (i) accept such Assignment and Acceptance,  (ii) record the information
contained  therein in the Register and (iii) give prompt  notice  thereof to the
Borrowers  and each  other  Agent.  In the case of any  assignment  by a Lender,
within five Business Days after its receipt of such notice,  the  Borrowers,  at
its own  expense,  shall  execute  and  deliver to the  Administrative  Agent in
exchange  for the  surrendered  Note or  Notes a new  Note to the  order of such
Eligible Assignee in an amount equal to the Commitment  assumed by it under each
Facility pursuant to such Assignment and Acceptance and, if any assigning Lender
has retained a Commitment hereunder under such Facility, a new Note to the order
of such  assigning  Lender in an amount equal to the  Commitment  retained by it
hereunder.  Such new Note or Notes  shall be in an  aggregate  principal  amount
equal to the aggregate principal amount of such surrendered Note or Notes, shall
be  dated  the  effective  date of such  Assignment  and  Acceptance  and  shall
otherwise be in substantially the form of Exhibit A-1, A-2 or A-3 hereto, as the
case may be.

     (f) The Issuing Bank may assign to Eligible  Assignee all of its rights and
obligations  under the undrawn portion of its Letter of Credit Commitment at any
time; provided,  however,  that (i) each such assignment shall be to an Eligible
Assignee and (ii) the parties to each such assignment  shall execute and deliver
to the  Administrative  Agent, for its acceptance and recording in the Register,
an Assignment and Acceptance,  together with a processing and recordation fee of

than any Loan Party or any of its  Affiliates)  in or to all or a portion of its
rights and obligations under this Agreement (including,  without limitation, all
or a portion of its Commitments,  the Advances owing to it and the Note or Notes
(if  any)  held  by  it);  provided,  however,  that  (i)  such  Lender  Party's
obligations   under  this  Agreement   (including,   without   limitation,   its
Commitments) shall remain unchanged,  (ii) such Lender Party shall remain solely
responsible to the other parties hereto for the performance of such obligations,

<PAGE>

Parties  shall  continue to deal solely and  directly  with such Lender Party in
connection with such Lender Party's rights and obligations  under this Agreement
and (v) no  participant  under any such  participation  shall  have any right to
approve any  amendment or waiver of any provision of any Loan  Document,  or any
consent to any departure by any Loan Party therefrom,  except to the extent that
such amendment, waiver or consent would reduce the principal of, or interest on,
the Notes or any fees or other amounts  payable  hereunder,  in each case to the
extent subject to such participation, postpone any date fixed for any payment of
principal  of, or interest  on, the Notes or any fees or other  amounts  payable
hereunder, in each case to the extent subject to such participation,  or release
all or substantially all of the Collateral.

     (h)  Any  Lender  Party  may,  in   connection   with  any   assignment  or
participation or proposed  assignment or participation  pursuant to this Section
9.07,   disclose  to  the  assignee  or  participant  or  proposed  assignee  or
participant any information  relating to the Borrowers  furnished to such Lender
Party by or on behalf of the Borrowers;  provided,  however,  that, prior to any
such disclosure, the assignee or participant or proposed assignee or participant
shall agree to preserve  the  confidentiality  of any  Confidential  Information
received by it from such Lender Party.

     (i)  Notwithstanding  any other provision set forth in this Agreement,  any
Lender Party may at any time create a security interest in all or any portion of
its rights under this Agreement  (including,  without  limitation,  the Advances
owing to it and the Note or Notes  held by it) in favor of any  Federal  Reserve
Bank in  accordance  with  Regulation A of the Board of Governors of the Federal
Reserve System.

     SECTION 9.08. Execution in Counterparts.  This Agreement may be executed in
any  number  of  counterparts  and  by  different  parties  hereto  in  separate
counterparts,  each of which when so executed  shall be deemed to be an original
and all of which taken  together shall  constitute  one and the same  agreement.
Delivery of an executed  counterpart  of a signature  page to this  Agreement by
telecopier shall be effective as delivery of an original executed counterpart of
this Agreement.

     SECTION 9.09. No Liability of the Issuing  Bank.  The Borrowers  assume all
risks of the acts or omissions of any beneficiary or transferee of any Letter of
Credit  with  respect to its use of such  Letter of Credit.  Neither the Issuing
Bank nor any of its officers or directors  shall be liable or  responsible  for:
(a) the use that may be made of any Letter of Credit or any acts or omissions of
any  beneficiary  or  transferee  in  connection  therewith;  (b) the  validity,
sufficiency or genuineness of documents,  or of any endorsement thereon, even if
such documents should prove to be in any or all respects invalid,  insufficient,
fraudulent or forged;  (c) payment by the Issuing Bank against  presentation  of
documents  that do not comply  with the terms of a Letter of  Credit,  including
failure of any  documents  to bear any  reference  or adequate  reference to the
Letter of Credit; or (d) any other circumstances whatsoever in making or failing
to make payment under any Letter of Credit, except that the Borrowers shall have
a claim  against the Issuing  Bank,  and the Issuing Bank shall be liable to the
Borrowers, to the extent of any direct, but not consequential,  damages suffered
by the Borrowers that the Borrowers  prove were caused by (i) the Issuing Bank's
willful misconduct or gross negligence as determined in a final,  non-appealable
judgment by a court of competent  jurisdiction in determining  whether documents
presented  under any  Letter of Credit  comply  with the terms of the  Letter of
Credit or (ii) the Issuing Bank's willful failure to make lawful payment under a
Letter  of  Credit  after the  presentation  to it of a draft  and  certificates
strictly  complying  with the terms and  conditions of the Letter of Credit.  In


                                       97

furtherance and not in limitation of the foregoing,  the Issuing Bank may accept
documents that appear on their face to be in order,  without  responsibility for
further investigation, regardless of any notice or information to the contrary.

     SECTION 9.10. Confidentiality. Neither any Agent nor any Lender Party shall
disclose any  Confidential  Information to any Person without the consent of the
Borrower,  other than (a) to such Agent's or such Lender Party's  Affiliates and
their  officers,  directors,  employees,  agents and  advisors  and to actual or
prospective Eligible Assignees and participants, and then only on a confidential
basis, (b) as required by any law, rule or regulation or judicial  process,  (c)
as requested or required by any state,  Federal or foreign authority or examiner
regulating  such Lender Party and (d) to any rating  agency when required by it,
provided that, prior to any such disclosure,  such rating agency shall undertake
to preserve the confidentiality of any Confidential  Information relating to the
Loan Parties received by it from such Lender Party.

     SECTION 9.11.  Release of  Collateral.  Upon the sale,  lease,  transfer or
other  disposition  of any  item of  Collateral  of any Loan  Party  (including,
without limitation, as a result of the sale, in accordance with the terms of the
Loan Documents,  of the Loan Party that owns such Collateral) in accordance with
the terms of the Loan  Documents,  the Collateral  Agent will, at the Borrowers'
expense,  execute  and  deliver to such Loan Party such  documents  as such Loan
Party may reasonably  request to evidence the release of such item of Collateral
from the assignment and security interest granted under the Collateral Documents
in accordance with the terms of the Loan Documents.

     SECTION  9.12.  Jurisdiction,  Etc. (a) Each of the parties  hereto  hereby
irrevocably and  unconditionally  submits,  for itself and its property,  to the
nonexclusive  jurisdiction  of any New York State court or Federal  court of the
United States of America  sitting in New York City, and any appellate court from
any  thereof,  in any action or  proceeding  arising  out of or relating to this
Agreement  or any of the other  Loan  Documents  to which it is a party,  or for
recognition  or  enforcement  of any  judgment,  and each of the parties  hereto
hereby irrevocably and unconditionally  agrees that all claims in respect of any
such action or proceeding may be heard and determined in any such New York State
court or, to the fullest extent permitted by law, in such Federal court. Each of
the  Loan  Parties  hereby  agrees  that  service  of all  process  in any  such
proceeding in any such court may be made by registered  mail or certified  mail,
return receipt requested,  to such Loan Party at its address provided in Section
9.02. Each of the parties hereto agrees that a final judgment in any such action
or proceeding shall be conclusive and may be enforced in other  jurisdictions by
suit on the  judgment or in any other  manner  provided by law.  Nothing in this
Agreement  shall affect any right that any party may otherwise have to bring any
action  or  proceeding  relating  to this  Agreement  or any of the  other  Loan
Documents in the courts of any jurisdiction.

     (b) Each of the parties hereto irrevocably and  unconditionally  waives, to
the fullest  extent it may legally and  effectively do so, any objection that it
may now or  hereafter  have to the  laying  of  venue  of any  suit,  action  or
proceeding arising out of or relating to this Agreement or any of the other Loan
Documents to which it is a party in any New York State or Federal court. Each of
the parties hereto hereby irrevocably waives, to the fullest extent permitted by
law, the defense of an  inconvenient  forum to the maintenance of such action or
proceeding in any such court.

     SECTION 9.13. Governing Law. This Agreement and the Notes shall be governed
by, and construed in accordance with, the laws of the State of New York.

                                       98

     SECTION 9.14. Waiver of Jury Trial.  Each of the Borrowers,  the Agents and
the Lender Parties  irrevocably waives all right to trial by jury in any action,
proceeding  or  counterclaim  (whether  based on  contract,  tort or  otherwise)
arising out of or  relating  to any of the Loan  Documents,  the  Advances,  the
Letters  of  Credit  or the  actions  of any  Agent or any  Lender  Party in the
negotiation, administration, performance or enforcement thereof.

     IN WITNESS  WHEREOF,  the parties  hereto have caused this  Agreement to be
executed by their respective officers thereunto duly authorized,  as of the date
first above written.

obligations or duties of any of the Grantors thereunder or to take any action to

intermediary  directing  transfer or redemption of the financial  asset to which

without  further  consent  of such  Grantor,  such  agreement  to be in form and
substance satisfactory to the Collateral Agent.

                                       10
<PAGE>

               (i) The rights of such Grantor in or to the Intellectual Property
          Collateral do not conflict with,  misappropriate  or infringe upon the
          intellectual property rights of any third party, and no claim has been
          asserted that the use of such Intellectual Property Collateral does or
          may infringe upon the intellectual property rights of any third party.

               (ii)  Such  Grantor  is the  exclusive  owner of the  entire  and
          unencumbered  right,  title and  interest  in and to the  Intellectual
          Property  Collateral  and is  entitled  to use all  such  Intellectual
          Property  Collateral without  limitation,  subject only to the license
          terms of the Licenses.

               (iii) The Intellectual  Property Collateral set forth on Schedule
          IV hereto includes all of the patents, patent applications,  trademark
          registrations   and   applications,    copyright   registrations   and
          applications and Licenses owned by such Grantor.

               (iv) The Intellectual  Property  Collateral is subsisting and has
          not been adjudged  invalid or  unenforceable  in whole or part, and to
          the best of such Grantor's knowledge,  is valid and enforceable.  Such
          Grantor is not aware of any uses of any item of Intellectual  Property
          Collateral  that  could  be  expected  to lead to such  item  becoming
          invalid or unenforceable.

               (v) Such  Grantor has made or performed  all filings,  recordings
          and other acts and has paid all  required  fees and taxes to  maintain
          and  protect  its  interest  in each and  every  item of  Intellectual
          Property Collateral in full force and effect throughout the world, and
          to protect  and  maintain  its  interest  therein  including,  without
          limitation,  recordations  of any of its  interests in the Patents and
          Trademarks  with  the  U.S.   Patent  and  Trademark   Office  and  in
          corresponding   national  and   international   patent  offices,   and
          recordation  of any of its interests in the  Copyrights  with the U.S.
          Copyright  Office  and in  corresponding  national  and  international
          copyright  offices.  Such Grantor has used proper  statutory notice in
          connection with its use of each patent, trademark and copyright of the
          Intellectual Property Collateral.

               (vi) No action, suit, investigation, litigation or proceeding has
          been  asserted  or  is  pending  or  (to  such  Grantor's   knowledge)
          threatened  against  such  Grantor  (i) based upon or  challenging  or
          seeking  to  deny  or  restrict  the  use of  any of the  Intellectual
          Property  Collateral,  or (ii) alleging that any services provided by,
          processes used by, or products  manufactured  or sold by, such Grantor
          infringe upon or misappropriate  any patent,  trademark,  copyright or
          any other  proprietary  right of any third party.  To the best of such
          Grantor's  knowledge,  no  Person is  engaging  in any  activity  that
          infringes upon or misappropriates the Intellectual Property Collateral
          or upon the  rights of such  Grantor  therein.  Except as set forth on
          Schedule IV hereto, such Grantor has not granted any license, release,
          covenant not to sue,  non-assertion  assurance,  or other right to any
          Person  with  respect  to  any  part  of  the  Intellectual   Property
          Collateral.  The consummation of the transactions  contemplated by the
          Transaction Documents will not result in the termination or impairment
          of any of the Intellectual Property Collateral.

                                       11

               (vii) With respect to each material License:  (A) such License is
          valid and  binding  and in full force and effect  and  represents  the
          entire  agreement  between the  respective  licensor and licensee with
          respect to the subject  matter of such License;  (B) such License will
          not  cease to be valid and  binding  and in full  force and  effect on
          terms identical to those currently in effect as a result of the rights
          and  interest  granted  herein,  nor will the grant of such rights and
          interest  constitute  a  breach  or  default  under  such  License  or
          otherwise  give the  licensor  or licensee a right to  terminate  such
          License;  (C) such Grantor has not received any notice of  termination
          or cancellation under such License;  (D) such Grantor has not received
          any notice of a breach or default under such License,  which breach or
          default  has not been cured;  (E) such  Grantor has not granted to any
          other  third  party any  rights,  adverse  or  otherwise,  under  such
          License;  and (F)  neither  such  Grantor  nor any other party to such
          License is in breach or default in any material respect,  and no event
          has  occurred  that,  with  notice  or lapse  of time or  both,  would
          constitute   such  a  breach  or   default   or  permit   termination,
          modification  or  acceleration  under  such  License,  except for such
          events  that  could not  reasonably  be  expected  to have a  Material
          Adverse Effect.

               (viii) To the best of such Grantor's acknowledge, (A) none of the
          Trade  Secrets of such Grantor has been used,  divulged,  disclosed or
          appropriated  to the  detriment of such Grantor for the benefit of any
          other Person  other than such  Grantor;  (B) no employee,  independent
          contractor  or agent of such  Grantor  has  misappropriated  any trade
          secrets of any other Person in the course of the performance of his or
          her duties as an  employee,  independent  contractor  or agent of such
          Grantor; and (C) no employee,  independent contractor or agent of such
          Grantor  is in  default  or  breach  of any  term  of  any  employment
          agreement,   non-disclosure   agreement,   assignment   of  inventions
          agreement or similar  agreement or contract relating in any way to the
          protection,  ownership, development, use or transfer of such Grantor's
          Intellectual Property Collateral in any material respect.

          Section 8. Further Assurances.  (a) Each Grantor agrees that from time
to time, at the expense of such Grantor,  such Grantor will promptly execute and
deliver all further instruments and documents, and take all further action, that
may be necessary  or  desirable,  or that the  Collateral  Agent may  reasonably
request  (including,  without  limitation,  procuring third party consents),  in
order to perfect and protect any pledge, assignment or security interest granted
or purported to be granted hereby or to enable the Collateral  Agent to exercise
and enforce its rights and remedies  hereunder  with respect to any  Collateral.

included in the Receivables, each Related Contract, each Assigned Agreement and,
at the request of the Collateral  Agent,  each of its records  pertaining to the

Agreement or Collateral is subject to the security interest granted hereby; (ii)
if any Collateral shall be evidenced by a promissory note or other instrument or

more financing or continuation statements,  and amendments thereto,  relating to
all or any part of the  Collateral  without the  signature of such Grantor where

sufficient as a financing statement where permitted by law.

          (c) Each  Grantor will  furnish to the  Collateral  Agent from time to
time statements and schedules further  identifying and describing the Collateral
and such other reports in connection with the Collateral as the Collateral Agent

Agreement and of any chattel paper and shall  deliver to the  Collateral  Agent,
forthwith upon execution thereof, such original executed copy, together with all
other  documents  ancillary  thereto or  delivered  by the  relevant  parties in
connection  therewith.  Such  Grantor  shall  mark  each  copy  of any  Assigned

possession  of the  Collateral  Agent,  (iii) that such  Assigned  Agreement  or

against  such  risks,  in  such  form  and  with  such  insurers,  as  shall  be
satisfactory to the Collateral Agent from time to time. Each policy for property
insurance  shall  provide for all losses to be paid on behalf of the  Collateral
Agent and such  Grantor  as their  interests  may  appear,  and each  policy for
property  damage  insurance  shall provide for all losses  (except for losses of

Agent.  Each  such  policy  shall in  addition  (i) name  such  Grantor  and the
Collateral Agent as insured parties  thereunder  (without any  representation or
warranty by or  obligation  upon the  Collateral  Agent) as their  interests may
appear, (ii) contain the agreement by the insurer that any loss thereunder shall
be payable to the  Collateral  Agent  notwithstanding  any  action,  inaction or

insurance and, as often as the Collateral Agent may reasonably request, a report
of a reputable  insurance broker with respect to such insurance.  Further,  each
Grantor shall, at the request of the Collateral Agent, duly exercise and deliver
instruments  of  assignment  of such  insurance  policies  to  comply  with  the
requirements  of Section 8 and cause the insurers to acknowledge  notice of such
assignment.

          (b)  Reimbursement  under any  liability  insurance  maintained by any
Grantor pursuant to this Section 10 may be paid directly to the Person who shall
have incurred liability covered by such insurance. In case of any loss involving
damage to Equipment or Inventory  when  subsection (c) of this Section 10 is not
applicable,  the applicable Grantor shall make or cause to be made the necessary
repairs to or replacements of such Equipment or Inventory as deemed desirable in
the reasonable opinion of the Grantor,  and any proceeds of insurance maintained
by such  Grantor  pursuant to this  Section 10 shall be paid to such  Grantor as
reimbursement for the costs of such repairs or replacements.

          (c) Upon the occurrence  and during the  continuance of any Default or
the actual or  constructive  total loss (in excess of $5,000,000 per occurrence)
of any  Equipment  or  Inventory,  all  insurance  payments  in  respect of such
Equipment or Inventory  shall be paid to and applied by the Collateral  Agent as
specified in Section 20(b).

          Section 11. Place of Perfection;  Records;  Collection of Receivables.
(a) Each  Grantor  shall keep its chief  place of business  and chief  executive
office and the office where it keeps its records concerning the Collateral,  and
any copies of the  Assigned  Agreements  not  required  to be  delivered  to the
Collateral  Agent  hereunder and any copies of all chattel paper not required to
be delivered to the Collateral Agent hereunder that evidence Receivables, at the
location  therefor  specified  in Section  7(a) or, upon 30 days' prior  written
notice to the Collateral Agent, at such other locations in a jurisdiction  where
all  actions  required  by Section 8 shall  have been taken with  respect to the
Collateral  of such  Grantor.  Each Grantor will hold and preserve such records,
Assigned  Agreements  and chattel paper and will permit  representatives  of the
Collateral Agent at any time during normal business hours upon reasonable notice
to inspect and make abstracts from such records, Assigned Agreements and chattel
paper.  If the  jurisdiction of the securities  intermediary  that maintains the
security account carrying the Pledged  Security  Entitlements  shall change from
that  jurisdiction  specified in Section  7(f),  the  applicable  Grantor  shall
promptly   notify  the  Collateral   Agent  of  such  change  and  of  such  new
jurisdiction.

                                       14

          (b) Except as otherwise  provided in this subsection (b), each Grantor
shall continue to collect, at its own expense,  all amounts due or to become due
such Grantor under the Receivables in the manner such Grantor currently collects
such amounts. In connection with such collections made in respect of Receivables
owing from a Person being an affiliate  of such  Grantor,  such Grantor may take
(and,  at the  Collateral  Agent's  direction,  shall  take) such action as such
Grantor or the Collateral  Agent may  reasonably  deem necessary or advisable to
enforce or expedite collection of the Receivables;  provided,  however, that the
Collateral  Agent shall have the right at any time,  upon written notice to such
Grantor of its intention to do so, to notify the Obligors under any  Receivables
of the assignment of such Receivables to the Collateral Agent and to direct such
Obligors to make  payment of all  amounts  due or to become due to such  Grantor
thereunder  directly to the  Collateral  Agent or its  designee  and,  upon such
notification  and at the expense of such Grantor,  to enforce  collection of any
such Receivables directly against the relevant Obligor, and to adjust, settle or
compromise  the amount or payment  thereof,  in the same  manner and to the same
extent as such Grantor might have done. In connection with such collections made
in respect of Receivables  owing from a Person not an affiliate of such Grantor,
such Grantor may take (and, at the Collateral  Agent's  direction,  shall take),
after the occurrence and during the  continuance of any Default,  such action as
such Grantor or the Collateral  Agent may reasonably deem necessary or advisable
to enforce or expedite collection of the Receivables;  provided,  however,  that
the  Collateral  Agent shall have the right at any time after the occurrence and
during the  continuance  of any Default,  upon written notice to such Grantor of
its  intention to do so, to notify the  Obligors  under any  Receivables  of the
assignment  of such  Receivables  to the  Collateral  Agent and to  direct  such
Obligors to make  payment of all  amounts  due or to become due to such  Grantor
thereunder  directly to the  Collateral  Agent or its  designee  and,  upon such
notification  and at the expense of such Grantor,  to enforce  collection of any
such Receivables directly against the relevant Obligor, and to adjust, settle or
compromise  the amount or payment  thereof,  in the same  manner and to the same
extent as such  Grantor  might have done.  After  receipt by such Grantor of the
notice from the  Collateral  Agent  referred to in the proviso to the  preceding
sentences, (i) all amounts and proceeds (including instruments) received by such
Grantor in respect of the Receivables shall be received in trust for the benefit
of the Collateral Agent hereunder,  shall be segregated from other funds of such
Grantor and shall be  forthwith  paid over to the  Collateral  Agent in the same
form as so received (with any necessary indorsement) and (ii) such Grantor shall
not  adjust,  settle or  compromise  the amount or  payment  of any  Receivable,
release  wholly or partly any Obligor  thereof,  or allow any credit or discount
thereon.

          (c) No Grantor  will  permit or consent  to the  subordination  of its
right to payment under any of the  Receivables  or the Related  Contracts to any
other indebtedness or obligations of the Obligor thereof.

          SECTION 12.  As to Intellectual Property Collateral.

          (a) With respect to each item of its Intellectual Property Collateral,
each Grantor  agrees to take, at its expense,  all necessary  steps,  including,
without limitation,  in the U.S. Patent and Trademark Office, the U.S. Copyright
Office and any other  governmental  authority,  to (i) maintain the validity and
enforceability  of  each  such  item of  Intellectual  Property  Collateral  and
maintain each such item of  Intellectual  Property  Collateral in full force and
effect,  and (ii)  pursue  the  registration  and  maintenance  of each  patent,
trademark,  or copyright registration or application,  now or hereafter included
in the  Intellectual  Property  Collateral of such Grantor,  including,  without
limitation,  the payment of required fees and taxes,  the filing of responses to
office  actions  issued  by the  U.S.  Patent  and  Trademark  Office,  the U.S.


                                       15
<PAGE>

Copyright Office or other governmental  authorities,  the filing of applications
for renewal or extension,  the filing of affidavits  under  Sections 8 and 15 of
the   U.S.   Trademark   Act,   the   filing   of   divisional,    continuation,
continuation-in-part,  reissue  and  renewal  applications  or  extensions,  the
payment   of   maintenance   fees  and  the   participation   in   interference,
reexamination,   opposition,  cancellation,  infringement  and  misappropriation
proceedings.  No Grantor  shall,  without the written  consent of the Collateral
Agent,  discontinue  use  of or  otherwise  abandon  any  Intellectual  Property
Collateral,  or abandon any right to file an  application  for  letters  patent,
trademark,  or copyright,  unless such Grantor shall have previously  determined
that  such use or the  pursuit  or  maintenance  of such  Intellectual  Property
Collateral is no longer desirable in the conduct of such Grantor's  business and
that the loss thereof would not be reasonably  likely to have a Material Adverse
Effect,  in which  case,  such  Grantor  will  give  prompt  notice  of any such
abandonment to the Collateral Agent.

          (b) Each Grantor  agrees  promptly to notify the  Collateral  Agent if
such Grantor learns (i) that any item of the  Intellectual  Property  Collateral
may  have  become   abandoned,   placed  in  the  public   domain,   invalid  or
unenforceable,  or of any adverse  determination  or development  regarding such
Grantor's ownership of any of the Intellectual  Property Collateral or its right
to register the same or to keep and  maintain  and enforce the same,  or (ii) of
any adverse  determination  or the  institution  of any  proceeding  (including,
without  limitation,  the  institution of any proceeding in the U.S.  Patent and
Trademark Office or any court)  regarding any item of the Intellectual  Property
Collateral.

          (c) In the event that any Grantor  becomes  aware that any item of the
Intellectual  Property  Collateral is being  infringed or  misappropriated  by a
third party,  such Grantor shall promptly notify the Collateral  Agent and shall
take such actions, at its expense, as such Grantor or the Collateral Agent deems
reasonable and appropriate  under the circumstances to protect such Intellectual
Property Collateral,  including,  without limitation,  suing for infringement or
misappropriation   and  for  an   injunction   against  such   infringement   or
misappropriation.

          (d) Each Grantor shall use proper  statutory notice in connection with
its use of each item of its Intellectual  Property Collateral.  No Grantor shall
do or  permit  any  act or  knowingly  omit  to do any  act  whereby  any of its
Intellectual Property Collateral may lapse or become invalid or unenforceable or
placed in the public domain.

          (e) Each Grantor shall take all steps which it or the Collateral Agent
deems reasonable and appropriate under the circumstances to preserve and protect
each  item  of  its  Intellectual   Property  Collateral,   including,   without
limitation,  maintaining the quality of any and all products or services used or
provided in connection with any of the  Trademarks,  consistent with the quality
of the  products  and  services  as of the date  hereof,  and  taking  all steps
necessary to ensure that all licensed  users of any of the  Trademarks  use such
consistent standards of quality.

          (f) With respect to its Intellectual Property Collateral, each Grantor
agrees to execute an agreement, in substantially the form set forth in Exhibit D
hereto (an  "Intellectual  Property  Security  Agreement"),  for  recording  the
security interest granted hereunder to the Collateral Agent in such Intellectual
Property  Collateral  with  the  U.S.  Patent  and  Trademark  Office,  the U.S.
Copyright Office and any other governmental authorities necessary to perfect the
security interest hereunder in such Intellectual Property Collateral.

                                       16
<PAGE>

          (g) Each Grantor agrees that,  should it obtain an ownership  interest
in any item of the  type set  forth  in  Section  1(g)  which is not on the date
hereof  a part of the  Intellectual  Property  Collateral  (the  "After-Acquired
Intellectual  Property"),  (i) the  provisions of Section 1 shall  automatically
apply thereto,  (ii) any such After-Acquired  Intellectual  Property and, in the
case  of  trademarks,  the  goodwill  of the  business  connected  therewith  or
symbolized thereby, shall automatically become part of the Intellectual Property
Collateral  subject to the terms and  conditions of this  Agreement with respect
thereto,  (iii) such Grantor  shall give prompt  written  notice  thereof to the
Collateral Agent in accordance  herewith and (iv) such Grantor shall execute and
deliver to the Collateral  Agent an IP Security  Agreement  Supplement  covering
such After-Acquired  Intellectual Property as "Additional Collateral" thereunder
and as defined therein,  and shall record such IP Security Agreement  Supplement
with the U.S. Patent and Trademark  Office,  the U.S.  Copyright  Office and any
other  governmental  authorities  necessary  to perfect  the  security  interest
hereunder in such After-Acquired Intellectual Property.

          Section 13.  Voting Rights; Dividends; Etc.  (a)  So long as no
Event of Default shall have occurred and be continuing:

          (i) Each Grantor  shall be entitled to exercise any and all voting and
     other consensual rights  pertaining to its Security  Collateral or any part
     thereof for any purpose not  inconsistent  with the terms of this Agreement
     or the other Loan Documents; provided, however, that such Grantor shall not
     exercise or refrain from  exercising  any such right if, in the  Collateral
     Agent's  judgment,  such action would have a material adverse effect on the
     value of the Security Collateral or any part thereof.

          (ii) Each Grantor  shall be entitled to receive and retain any and all
     dividends, interest and other distributions paid in respect of its Security
     Collateral; provided, however, that any and all

               (A) dividends,  interest and other  distributions paid or payable
          other than in cash in respect of, and  instruments  and other property
          received,  receivable  or otherwise  distributed  in respect of, or in
          exchange for, such Security Collateral,

               (B) dividends and other  distributions paid or payable in cash in
          respect of such Security  Collateral  in connection  with a partial or
          total  liquidation or dissolution or in connection with a reduction of
          capital, capital surplus or paid-in-surplus and

               (C) cash paid,  payable or  otherwise  distributed  in respect of
          principal  of, or in  redemption  of, or in exchange for, any Security
          Collateral

     shall be, and shall be forthwith  delivered to the Collateral Agent to hold
     as, Security Collateral and shall, if received by such Grantor, be received
     in trust for the benefit of the Collateral  Agent,  be segregated  from the
     other  property or funds of such Grantor and be forthwith  delivered to the
     Collateral  Agent as  Security  Collateral  in the same form as so received
     (with any necessary indorsement).

          (iii) The  Collateral  Agent shall execute and deliver (or cause to be
     executed  and  delivered)  to each  Grantor  all  such  proxies  and  other


                                       17
<PAGE>

     instruments  as such  Grantor  may  reasonably  request  for the purpose of
     enabling  such  Grantor to exercise  the voting and other rights that it is
     entitled to exercise  pursuant  to  paragraph  (i) above and to receive the
     dividends or interest  payments that it is authorized to receive and retain
     pursuant to paragraph (ii) above.

          (b)     Upon the occurrence and during the continuance of a Default
or an Event of Default:

          (i) All  rights  of each  Grantor  (x) to  exercise  or  refrain  from
     exercising the voting and other  consensual  rights that it would otherwise
     be entitled to exercise  pursuant to Section 13(a)(i) shall, upon notice to
     such  Grantor  by the  Collateral  Agent,  cease  and  (y) to  receive  the
     dividends,  interest  and other  distributions  that it would  otherwise be
     authorized  to receive  and retain  pursuant  to  Section  13(a)(ii)  shall
     automatically  cease,  and all such rights shall thereupon become vested in
     the Collateral Agent, which shall thereupon have the sole right to exercise
     or refrain from exercising such voting and other  consensual  rights and to
     receive and hold as Security Collateral such dividends,  interest and other
     distributions.

          (ii) All dividends, interest and other distributions that are received
     by each Grantor contrary to the provisions of paragraph (i) of this Section
     13(b) shall be received in trust for the benefit of the  Collateral  Agent,
     shall be segregated from other funds of such Grantor and shall be forthwith
     paid over to the Collateral  Agent as Security  Collateral in the same form
     as so received (with any necessary indorsement).

          Section 14.  As to the Assigned Agreements.  (a)  Each Grantor shall
at its expense:

          (i) perform and observe all the terms and  provisions  of the Assigned
     Agreements  to be  performed  or  observed  by it,  maintain  the  Assigned
     Agreements  in full force and effect,  enforce the Assigned  Agreements  in
     accordance with their terms and take all such reasonable action to such end
     as may be from time to time requested by the Collateral Agent; and

          (ii) furnish to the  Collateral  Agent  promptly upon receipt  thereof
     copies of all  notices,  requests  and  other  documents  received  by such
     Grantor under or pursuant to the Assigned Agreements, and from time to time
     (A) furnish to the Collateral Agent such information and reports  regarding
     the Collateral as the Collateral Agent may reasonably  request and (B) upon
     request of the  Collateral  Agent make to each other party to any  Assigned
     Agreement  such  demands and requests  for  information  and reports or for
     action as such Grantor is entitled to make thereunder.

          (b) Each Grantor agrees that it shall not:

          (i) cancel or terminate any Assigned Agreement or consent to or accept
     any cancellation or termination  thereof,  except in the ordinary course of
     business  and in a manner that would not  reasonably  be expected to have a
     Material Adverse Effect;

          (ii) amend or  otherwise  modify any  Assigned  Agreement  or give any
     consent, waiver or approval thereunder;

                                       18
<PAGE>

          (iii) waive any default under or breach of any Assigned Agreement; or

          (iv) take any other action in connection  with any Assigned  Agreement
     that would  materially  impair the value of the  interest or rights of such
     Grantor  thereunder or that would materially  impair the interest or rights
     of any Secured Party.

          (c) Each  Grantor  hereby  consents on its behalf and on behalf of its
Subsidiaries to the assignment and pledge to the Collateral Agent for benefit of
the Secured  Parties of each  Assigned  Agreement  to which it is a party by any
other Grantor hereunder.

          Section 15.  Payments  Under the  Assigned  Agreements.  Each  Grantor
agrees,  and has  effectively  so  instructed  each other party to each Assigned
Agreement,  that all payments due or to become due under or in  connection  with
such  Assigned  Agreement  shall be made in  accordance  with  the  terms of the
consents referred to in Section 7(g) above.

          Section 16.  Transfers and Other Liens;  Additional  Shares.  (a) Each
Grantor  agrees  that it shall not (i) other  than in  accordance  with the Loan
Documents,  sell, assign (by operation of law or otherwise) or otherwise dispose
of, or grant any option with respect to, any of the Collateral,  except sales of
Inventory in the ordinary course of business,  or (ii) create or suffer to exist
any Lien upon or with  respect to any of the  Collateral  except for the pledge,
assignment and security interest created by this Agreement.

          (b) Each  Grantor  agrees  that it shall (i) cause each  issuer of the
Pledged  Shares not to issue any stock or other  securities in addition to or in
substitution  for the  Pledged  Shares  issued  by such  issuer,  except to such
Grantor, and (ii) pledge hereunder,  immediately upon its acquisition  (directly
or  indirectly)  thereof,  any and all  additional  shares  of  stock  or  other
securities of each issuer of the Pledged Shares.

          Section 17. Collateral Agent Appointed Attorney-in-Fact.  Each Grantor
hereby    irrevocably    appoints   the   Collateral    Agent   such   Grantor's
attorney-in-fact, with full authority in the place and stead of such Grantor and
in the name of such Grantor or  otherwise,  from time to time in the  Collateral
Agent's  discretion,  to take any action and to execute any instrument  that the
Collateral  Agent may deem  necessary or advisable to accomplish the purposes of
this Agreement, including, without limitation:

          (a)  to  obtain  and  adjust  insurance  required  to be  paid  to the
     Collateral Agent pursuant to Section 10,

          (b) to ask for, demand, collect, sue for, recover, compromise, receive
     and give acquittance and receipts for moneys due and to become due under or
     in respect of any of the Collateral,

          (c) to receive,  indorse and collect any drafts or other  instruments,
     documents and chattel  paper,  in connection  with clause (a) or (b) above,
     and

                                       19
<PAGE>

          (d) to file any claims or take any action or institute any proceedings
     that  the  Collateral  Agent  may  deem  necessary  or  desirable  for  the
     collection of any of the Collateral or otherwise to enforce compliance with
     the terms and  conditions  of any  Assigned  Agreement or the rights of the
     Collateral Agent with respect to any of the Collateral.

          Section 18.  Collateral  Agent May  Perform.  If any Grantor  fails to
perform any agreement contained herein, the Collateral Agent may itself perform,
or cause  performance  of, such  agreement,  and the expenses of the  Collateral
Agent  incurred in connection  therewith  shall be payable by such Grantor under
Section 22(b).

          Section 19. The Collateral Agent's Duties. The powers conferred on the
Collateral Agent hereunder are solely to protect the Secured  Parties'  interest
in the  Collateral  and shall not impose any duty upon it to  exercise  any such
powers.  Except for the safe custody of any Collateral in its possession and the
accounting for moneys actually  received by it hereunder,  the Collateral  Agent
shall have no duty as to any  Collateral,  as to  ascertaining  or taking action
with  respect to calls,  conversions,  exchanges,  maturities,  tenders or other
matters  relative to any Collateral,  whether or not any Secured Party has or is
deemed to have  knowledge of such matters,  or as to the taking of any necessary
steps to preserve  rights against any parties or any other rights  pertaining to
any  Collateral.  The  Collateral  Agent  shall  be  deemed  to  have  exercised
reasonable  care  in the  custody  and  preservation  of any  Collateral  in its
possession if such Collateral is accorded treatment  substantially equal to that
which it accords its own property.

          (b) Anything  contained  herein to the contrary  notwithstanding,  the
Collateral Agent may from time to time, when the Collateral Agent deems it to be
necessary,  appoint one or more subagents (each a "Subagent") for the Collateral
Agent hereunder with respect to all or any part of the Collateral.  In the event
that  the  Collateral  Agent  so  appoints  any  Subagent  with  respect  to any
Collateral,  (i) the assignment  and pledge of such  Collateral and the security
interest  granted in such  Collateral by each Grantor  hereunder shall be deemed
for purposes of this Security  Agreement to have been made to such Subagent,  in
addition  to the  Collateral  Agent,  for the  ratable  benefit  of the  Secured
Parties,  as security for the Secured  Obligations  of such  Grantor,  (ii) such
Subagent shall  automatically  be vested,  in addition to the Collateral  Agent,
with all rights,  powers,  privileges,  interests and remedies of the Collateral
Agent hereunder with respect to such Collateral,  and (iii) the term "Collateral
Agent,"  when  used  herein  in  relation  to any  rights,  powers,  privileges,
interests and remedies of the Collateral  Agent with respect to such Collateral,
shall include such Subagent;  provided,  however, that no such Subagent shall be
authorized  to take any action with  respect to any such  Collateral  unless and
except to the extent expressly authorized in writing by the Collateral Agent.

          Section 20.  Remedies.  If any Event of Default shall have occurred
and be continuing:

          (a) The Collateral Agent may exercise in respect of the Collateral, in
     addition to other  rights and  remedies  provided  for herein or  otherwise
     available  to it,  all the  rights  and  remedies  of a secured  party upon
     default  under the N.Y.  Uniform  Commercial  Code (whether or not the N.Y.
     Uniform  Commercial  Code applies to the affected  Collateral) and also may
     (i) require any of the Grantors to, and each Grantor  hereby agrees that it
     will at its expense and upon  request of the  Collateral  Agent  forthwith,
     assemble all or part of the Collateral as directed by the Collateral  Agent
     and make it available to the  Collateral  Agent at a place to be designated
     by the Collateral  Agent that is reasonably  convenient to both parties and


                                       20
<PAGE>

     (ii) without notice except as specified  below,  sell the Collateral or any
     part  thereof in one or more parcels at public or private  sale,  at any of
     the  Collateral  Agent's  offices or elsewhere,  for cash, on credit or for
     future delivery, and upon such other terms as are commercially  reasonable;
     (iii) occupy any premises  owned or leased by any of the Grantors where the
     Collateral  or any part  thereof is  assembled  or located for a reasonable
     period in order to  effectuate  its rights and remedies  hereunder or under
     law, without obligation to such Grantor in respect of such occupation;  and
     (iv) exercise any and all rights and remedies of any of the Grantors  under
     or in connection  with the Assigned  Agreements,  the  Receivables  and the
     Related  Contracts or otherwise  in respect of the  Collateral,  including,
     without  limitation,  any and all  rights  of such  Grantor  to  demand  or
     otherwise  require  payment  of any amount  under,  or  performance  of any
     provision  of, the Assigned  Agreements,  the  Receivables  and the Related
     Contracts.  Each Grantor agrees that, to the extent notice of sale shall be
     required by law, at least ten days'  notice to such Grantor of the time and
     place of any public sale or the time after which any private  sale is to be
     made shall constitute reasonable  notification.  The Collateral Agent shall
     not be obligated  to make any sale of  Collateral  regardless  of notice of
     sale  having  been given.  The  Collateral  Agent may adjourn any public or
     private sale from time to time by  announcement at the time and place fixed
     therefor,  and such sale may,  without further notice,  be made at the time
     and place to which it was so adjourned.

          (b) All cash proceeds  received by the Collateral  Agent in respect of
     any sale of,  collection from, or other realization upon all or any part of
     the Collateral  may, in the discretion of the Collateral  Agent, be held by
     the  Collateral  Agent  as  collateral  for,  and/or  then  or at any  time
     thereafter  applied (after payment of any amounts payable to the Collateral
     Agent pursuant to Section 22) in whole or in part by the  Collateral  Agent
     for the ratable benefit of the Secured Parties against,  all or any part of
     the Secured  Obligations in such order as the Collateral Agent shall elect.
     Any surplus of such cash or cash proceeds held by the Collateral  Agent and
     remaining  after  payment in full of all the Secured  Obligations  shall be
     paid  over to the  applicable  Grantor  or to  whomsoever  may be  lawfully
     entitled to receive such surplus.

          (c) All payments  received by each Grantor under or in connection with
     any Assigned  Agreement or otherwise in respect of the Collateral  shall be
     received  in  trust  for the  benefit  of the  Collateral  Agent,  shall be
     segregated  from other funds of such  Grantor and shall be  forthwith  paid
     over to the  Collateral  Agent in the same  form as so  received  (with any
     necessary indorsement).

          (d) The Collateral  Agent may, without notice to any Grantor except as
     required by law and at any time or from time to time,  charge,  set-off and
     otherwise apply all or any part of the Secured Obligations against the Cash
     Collateral Account or the L/C Cash Collateral Account or any part thereof.

          (e) In the  event  of any  sale  or  other  disposition  of any of the
     Intellectual  Property  Collateral  of any  Grantor,  the  goodwill  of the
     business  connected with and  symbolized by any Trademarks  subject to such
     sale or other disposition shall be included therein, and such Grantor shall
     supply to the Collateral Agent or its designee such Grantor's  know-how and
     expertise,  and documents and things relating to any Intellectual  Property

                                       21

     Collateral  subject to such sale or other  disposition,  and such Grantor's
     customer   lists  and  other  records  and   documents   relating  to  such

          Section 21.  Registration  Rights. With respect to Security Collateral
issued by entities (controlled by a Grantor) where the securities are registered
under Section 12(b) or 12(g) of the  Securities  Act of 1934, if the  Collateral
Agent shall  determine  to exercise its right to sell all or any of the Security
Collateral pursuant to Section 20, each Grantor agrees that, upon request of the
Collateral Agent, such Grantor will, at its own expense:

          (a)  execute  and  deliver,  and cause  each  issuer  of the  Security
     Collateral  contemplated to be sold and the directors and officers  thereof
     to execute and deliver, all such instruments and documents, and do or cause
     to be done all such other acts and things,  as may be necessary  or, in the
     opinion of the  Collateral  Agent,  advisable  to  register  such  Security
     Collateral under the provisions of the Securities Act of 1933, as from time
     to time amended (the "Securities Act"), to cause the registration statement
     relating  thereto  to become  effective  and to remain  effective  for such
     period as prospectuses  are required by law to be furnished and to make all
     amendments and supplements  thereto and to the related  prospectus that, in
     the opinion of the  Collateral  Agent,  are necessary or advisable,  all in
     conformity  with the  requirements  of the Securities Act and the rules and
     regulations of the Securities and Exchange Commission applicable thereto;


          (b) use its best efforts to qualify the Security  Collateral under the
     state   securities   or  "Blue  Sky"  laws  and  to  obtain  all  necessary
     governmental  approvals  for  the  sale  of  the  Security  Collateral,  as
     requested by the Collateral Agent;

          (c) cause each such issuer to make available to its security  holders,
     as soon as  practicable,  an  earnings  statement  that  will  satisfy  the
     provisions of Section 11(a) of the Securities Act;

          (d)  provide  the  Collateral  Agent with such other  information  and
     projections as may be necessary or, in the opinion of the Collateral Agent,
     advisable  to  enable  the  Collateral  Agent  to  effect  the sale of such
     Security Collateral; and

          (e) do or cause to be done all such  other  acts and  things as may be
     necessary to make such sale of the Security  Collateral or any part thereof
     valid and binding and in compliance with applicable law.

The Collateral Agent is authorized,  in connection with any sale of the Security
Collateral  pursuant  to Section  19, to deliver or  otherwise  disclose  to any
prospective purchaser of the Security Collateral (i) any registration  statement
or prospectus,  and all supplements and amendments thereto, prepared pursuant to
clause (a) above,  (ii) any information and projections  provided to it pursuant
to clause (d) above and (iii) any other  information in its possession  relating
to the Security Collateral.

          Section  22.  Indemnity  and  Expenses.  (a) Each  Grantor  agrees  to
indemnify the Collateral  Agent from and against any and all claims,  losses and
liabilities growing out of or resulting from this Agreement (including,  without
limitation, enforcement of this Agreement), except claims, losses or liabilities
resulting from the Collateral  Agent's gross negligence or willful misconduct as
determined by a final judgment of a court of competent jurisdiction.

          (b) Each  Grantor  will upon  demand pay to the  Collateral  Agent the
amount of any and all reasonable  expenses,  including the  reasonable  fees and
expenses of its counsel and of any experts and agents, that the Collateral Agent
may incur in connection with (i) the administration of this Agreement,  (ii) the
custody,  preservation,  use or operation of, or the sale of, collection from or
other realization upon, any of the Collateral, (iii) the exercise or enforcement
of any of the rights of the Collateral Agent or the Secured Parties hereunder or
(iv) the  failure by such  Grantor to perform or observe  any of the  provisions
hereof.

          Section 23.  Amendments;  Waivers;  Etc. (a) No amendment or waiver of
any provision of this Agreement,  and no consent to any departure by any Grantor
herefrom,  shall in any event be  effective  unless the same shall be in writing
and signed by the  Collateral  Agent,  and then such waiver or consent  shall be
effective only in the specific  instance and for the specific  purpose for which
given.

          (b) No failure on the part of the Collateral Agent to exercise, and no
delay in exercising any right, power or privilege hereunder,  shall operate as a
waiver  thereof;  nor shall any single or partial  exercise  of any such  right,
power or  privilege  preclude  any  other or  further  exercise  thereof  or the
exercise of any other right, power or privilege.

          (c) Upon the  execution  and  delivery  by any  Person  of a  security
agreement  supplement  in  substantially  the form of  Exhibit A hereto  (each a
"Security  Agreement  Supplement"),  (i) such Person  shall be referred to as an
"Additional  Grantor" and shall be and become a Grantor,  and each  reference in
this  Agreement  to  "Grantor"  shall  also  mean  and be a  reference  to  such
Additional  Grantor and (ii) the Schedules  attached to each Security  Agreement
Supplement  shall  be  incorporated  into and  become  a part of and  supplement
Schedules  I  through  VI  hereto,  and the  Collateral  Agent may  attach  such
Schedules as supplements to such Schedules, and each reference to such Schedules
shall  mean and be a  reference  to such  Schedules,  as  supplemented  pursuant
hereto.

          Section   24.   Addresses   for   Notices.   All   notices  and  other
communications  provided for hereunder shall be in writing  (including  telecopy

expense,  execute and deliver to such  Grantor  such  documents  as such Grantor
shall reasonably request to evidence the release of such item of Collateral from
the assignment and security interest granted hereby; provided, however, that (i)
at the time of such request and such release no Default  shall have occurred and
be  continuing,  (ii)  the  applicable  Grantor  shall  have  delivered  to  the
Collateral  Agent,  at least ten Business Days prior to the date of the proposed
release, a written request for release describing the item of Collateral and the
terms of the sale, lease,  transfer or other  disposition in reasonable  detail,
including the price thereof and any expenses in connection  therewith,  together

Termination  Date,  and  the  Working  Capital  Termination  Date,  the  pledge,
assignment and security  interest  granted hereby shall terminate and all rights

Agent  will,  subject to the  provisions  of Section  20,  from time to time (a)
invest  amounts  on  deposit  in the Cash  Collateral  Account  and the L/C Cash
Collateral  Account in such Cash Equivalents (as to which all action required by
Section 8 shall have been taken) as such Borrower may select and the  Collateral
Agent may approve and (b) invest interest paid on the Cash Equivalents  referred
to in clause (a) above, and reinvest other proceeds of any such Cash Equivalents
that may mature or be sold, in each case in such Cash  Equivalents  (as to which
all actions  required by Section 8 shall have been taken) as such  Borrower  may
select and the Collateral Agent may approve (the Cash Equivalents referred to in
clauses (a) and (b) above being collectively "Collateral Investments"). Interest

be an original and all of which taken together shall constitute one and the same
agreement.  Delivery of an  executed  counterpart  of a  signature  page to this
Agreement by telecopier  shall be effective as delivery of an original  executed
counterpart of this Agreement.

          Section  29. The  Mortgages.  In the event that any of the  Collateral
hereunder is also subject to a valid and enforceable Lien under the terms of any
Mortgage and the terms of such Mortgage are inconsistent  with the terms of this
Agreement,  then with  respect to such  Collateral,  the terms of such  Mortgage
shall be  controlling  in the case of fixtures and leases,  letting and licenses
of, and contracts and agreements relating to the lease of real property, and the
terms  of  this  Agreement  shall  be  controlling  in the  case  of  all  other
Collateral.

construed in  accordance  with the laws of the State of New York,  except to the

remedies hereunder,  in respect of any particular Collateral are governed by the
laws of a jurisdiction other than the State of New York.

                              ICG NetAhead, Inc.


Ladies and Gentlemen:

     Reference is made to (i) the Credit  Agreement  dated as of August 12, 1999
(as amended, amended and restated,  supplemented or otherwise modified from time
to time,  the  "Credit  Agreement"),  among  ICG  Equipment,  Inc.,  a  Colorado
corporation,  ICG NetAhead,  Inc., a Delaware  corporation,  the Lender  Parties
party  thereto,  Royal Bank of Canada,  as collateral  agent  (together with any
successor  collateral  agent  appointed  pursuant  to Article  VII of the Credit
Agreement,  the "Collateral Agent"), and Royal Bank of Canada, as administrative
agent for the Lender Parties,  and (ii) the Security  Agreement dated August 12,
1999 (as amended, amended and restated,  supplemented or otherwise modified from
time to time, the "Security  Agreement")  made by the Grantors from time to time
party thereto in favor of the Collateral  Agent for the Secured  Parties.  Terms
defined in the Credit  Agreement or the  Security  Agreement  and not  otherwise
defined  herein  are used  herein as  defined  in the  Credit  Agreement  or the
Security Agreement.

          Section 1. Grant of  Security.  The  undersigned  hereby  assigns  and
pledges to the Collateral  Agent for the ratable benefit of the Secured Parties,
and hereby grants to the Collateral Agent for the ratable benefit of the Secured
Parties,  a security interest in, all of its right, title and interest in and to
all of the  Collateral  of the  undersigned,  whether  now  owned  or  hereafter
acquired by the  undersigned,  wherever  located  and  whether now or  hereafter
existing or arising,  including,  without limitation, the property and assets of
the  undersigned  set  forth  on  the  attached  supplemental  schedules  to the
Schedules to the Security Agreement.

          Section 2. Security for Obligations. The pledge and assignment of, and
the grant of a security  interest in, the  Collateral by the  undersigned  under
this  Security  Agreement  Supplement  and the  Security  Agreement  secures the
payment of all Obligations of the undersigned now or hereafter existing under or
in  respect of the Loan  Documents,  whether  direct or  indirect,  absolute  or
contingent,  and whether for  principal,  reimbursement  obligations,  interest,
premiums,  penalties, fees, indemnifications,  contract causes of action, costs,

<PAGE>

expenses or otherwise.  Without  limiting the generality of the foregoing,  this
Security Agreement  Supplement and the Security Agreement secures the payment of
all amounts that  constitute  part of the Secured  Obligations and that would be
owed by the  undersigned  to any Secured Party under the Loan  Documents but for
the fact that such Secured Obligations are unenforceable or not allowable due to
the existence of a bankruptcy,  reorganization or similar  proceeding  involving
the undersigned or any Grantor.

          Section  3.   Supplements  to  Security   Agreement   Schedules.   The
undersigned has attached hereto supplemental Schedules I, II, III, IV, V, VI and
VII to Schedules I, II, III,  IV, V, VI and VII,  respectively,  to the Security
Agreement,  and the  undersigned  hereby  certifies,  as of the date first above
written, that such supplemental  schedules have been prepared by the undersigned
in substantially the form of the equivalent  Schedules to the Security Agreement
and are complete and correct in all material respects.

          Section 4.  Representations  and Warranties.  The  undersigned  hereby
makes each  representation  and  warranty set forth in Section 7 of the Security
Agreement (as supplemented by the attached  supplemental  schedules) to the same
extent as each other Grantor.

          Section 5. Obligations Under the Security  Agreement.  The undersigned
hereby agrees,  as of the date first above written,  to be bound as a Grantor by
