                                     PART I


     Unless the context otherwise requires, the term "Company" or"ICG" means the
combined  business  operations  of ICG  Communications,  Inc.  ("ICG")  and  its
subsidiaries, including ICG Funding, LLC ("ICG Funding"), ICG Holdings (Canada),
Inc. ("Holdings-Canada") and ICG Holdings, Inc. ("Holdings"); the terms "fiscal"
and  "fiscal  year" refer to ICG's  fiscal year ending  December 31 for 1997 and
September 30 for years prior to 1997. 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.

ITEM 1. BUSINESS

Overview

     The  Company  is one  of the  nation's  leading  integrated  communications
providers ("ICPs") of competitive communications services, based on estimates of
the  industry's  1997 revenue.  ICPs seek to provide an alternative to incumbent
local exchange  carriers  ("ILECs"),  long distance  carriers,  Internet service
providers ("ISPs") and other  communications  service providers for a full range
of communications  services in the increasingly  deregulated  telecommunications
industry.  Through its competitive  local exchange carrier ("CLEC")  operations,
the  Company  operates   networks  in  four  regional  clusters  covering  major
metropolitan statistical areas in California,  Colorado, Ohio and the Southeast.
The Company also provides a wide range of network systems integration  services,
maritime and international satellite transmission services,  and subsequent to
January 21,  1998,  a variety of  Internet  connectivity  and other  value-added
Internet services.  As a leading  participant in the rapidly growing competitive
local  telecommunications  industry,  the  Company has  experienced  significant
growth,  with total revenue  increasing  from  approximately  $111.6 million for
fiscal 1995 to approximately $273.4 million for fiscal 1997.

     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.  Due to these
regulatory  changes,  the Company is now permitted to offer all  interstate  and
intrastate  telephone  services,  including  competitive  local dial  tone.  The
Company is marketing and selling local dial tone services in major  metropolitan
areas in the following regions:  California, which began service in late January
1997,  followed  by Ohio in  February  1997,  Colorado  in  March  1997  and the
Southeast  in May 1997.  During  fiscal  1997,  the Company  sold  approximately
178,000 local access lines, of which approximately 141,000 were in service as of
December 31, 1997. As a complement to its local  exchange  service,  the Company
has begun  marketing  bundled  service  offerings  which include long  distance,
enhanced  telecommunications  services  and data  services.  The  Company has 19
operating  high  capacity  digital  voice  switches  and 15 data  communications
switches, and plans to install additional switches as demand warrants.

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

Recent Developments

     Merger  with NETCOM  On-Line  Communication  Services,  Inc. On January 21,
1998, the Company completed a merger with NETCOM On-Line Communication Services,
Inc. ("NETCOM") ("NETCOM Merger"). Located in San Jose, California,  NETCOM is a
provider  of  Internet  connectivity  and World Wide Web  ("Web")  site  hosting
services and other value-added services. For calendar years 1995, 1996 and 1997,
NETCOM  reported  revenue of  approximately  $52.4  million,  $120.5 million and
$160.7 million, respectively, and EBITDA losses of approximately $(6.3) million,
$(20.3) million and $(1.7) million,  respectively.  The Company will account for
the business combination under the pooling of interests method of accounting.

     At the  effective  time of the NETCOM  Merger,  each  outstanding  share of
NETCOM common  stock,  $.01 par value,  became  automatically  convertible  into
shares of ICG common stock at an exchange  ratio of 0.8628  shares of ICG common
stock per NETCOM  common  share.  As a result of this  transaction,  the Company
expects to issue an estimated  10.2  million  shares of ICG common stock for the
NETCOM common shares  outstanding on January 21, 1998. Cash will be paid in lieu
of any fractional shares.

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

     Announcement of New Service Offerings. In March 1998, the Company announced
its plans to offer long distance service via Internet protocol ("IP") technology
at rates as low as 5.9 cents per  minute.  This  service  will be offered in 166
cities across the nation,  covering 90% of the U.S. long distance market, by the
end of fiscal  1998.  ICG and NETCOM will begin to market this  service over the
Internet and through its inbound  telemarketing  center in the second quarter of
1998.  The Company  also plans to offer by the end of fiscal 1998  competitively
priced high-speed data transmission services via digital subscriber line ("DSL")
technology to all business and end user customers  within its existing  regional
clusters. DSL technology utilizes the existing twisted copper pair connection to
the business or end user,  giving the customer  significantly  greater bandwidth
when connecting to the Internet.

     Acquisition of  Communications  Buying Group, Inc. On October 17, 1997, the
Company  purchased  approximately  91%  of  the  outstanding  capital  stock  of
Communications  Buying Group,  Inc.  ("CBG"),  an Ohio based local  exchange and
centrex reseller (the "CBG  Acquisition").  The Company paid total consideration
of  approximately  $46.5 million,  plus the  assumption of certain  liabilities.
Separately, on October 17, 1997, the Company sold approximately $16.0 million of
common stock, $.01 par value ("Common Stock"),  to certain  shareholders of CBG.
The Company  purchased the remaining  approximately  9% interest of CBG on March
24, 1998 for approximately $2.9 million in cash.

                                       7

     CBG  focuses  its  sales and  marketing  efforts  on small to  medium-sized
businesses  in certain  cities in Ohio and provides a one-stop  solution for the
local and long  distance  needs of its  customers.  For calendar  years 1996 and
1997,  CBG's  revenue  was  approximately   $21.4  million  and  $33.8  million,
respectively,  and EBITDA losses were  approximately  $(1.0)  million and $(3.2)
million, respectively.

     The Company  believes that the business  strategy of CBG is closely aligned
with the Company's  business strategy and that it can successfully  leverage the
services offered by CBG to enhance the Company's offering of similar services in
its existing Ohio markets,  including all those  currently  served by CBG. As of
December 31, 1997,  the  acquisition  of CBG has more than doubled the Company's
sales  presence in Ohio to  approximately  91 people.  In addition,  the Company
believes  that its ability to migrate,  over time,  a portion of CBG's  existing
customer base to its fiber optic facilities offers significant cost savings. The
Company  believes that the transaction has  significantly  furthered its goal of
becoming the dominant alternative to the ILEC in Ohio.

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

     CSW Strategic Alliance.  In January 1997, the Company announced a strategic
alliance  with Central and South West  Corporation  ("CSW") which was formed for
the purpose of developing and marketing  telecommunications  services in Austin,
Corpus Christi,  Dallas,  Houston and San Antonio,  Texas. The venture entity, a
limited  partnership named CSW/ICG ChoiceCom,  L.P.  ("ChoiceCom"),  is based in
Austin,  Texas.  CSW holds 100% of the interest in ChoiceCom and the Company has
an  option  to  purchase  a 50%  interest  at any time  prior  to July 1,  2003.
Subsequent  to July 1, 1999,  if the  Company  has not  exercised  its  purchase
option, CSW will have the right to sell, at a price pursuant to the terms of the
limited partnership agreement, either 51% or 100% of the partnership interest in
ChoiceCom to the Company.  CSW and the Company each have two  representatives on
the  Management  Committee  of the general  partner of  ChoiceCom.  ChoiceCom is
currently  offering  local  exchange,  long  distance and long haul  services in
Austin,  Corpus  Christi,  Dallas,  Houston  and San  Antonio,  Texas  and other
selected  areas  of  Texas  and  may  offer  these  services  as  well  as  data
communications and other services in Arkansas, Louisiana and Oklahoma.

     Financings.  In March  1997,  the  Company  raised net  proceeds  of $192.4
million  from the sale of 11 5/8% Senior  Discount  Notes due 2007 (the "11 5/8%
Notes") of Holdings and 14% Exchangeable  Preferred Stock Mandatorily Redeemable
2008 (the "14% Preferred Stock") of Holdings. Cash interest on the 11 5/8% Notes
accrues at 11 5/8% per annum  beginning March 15, 2002 and is payable each March
15 and September 15,  commencing  September  15, 2002.  The 14% Preferred  Stock
accrues  dividends  quarterly at a rate of 14% per annum.  Dividends are payable
quarterly  in cash or,  on or prior to March  15,  2002,  at the sole  option of
Holdings, in additional shares of 14% Preferred Stock. The 11 5/8% Notes and the
14% Preferred Stock have been registered under the Securities Act.

     In September and October 1997,  the Company's new wholly owned  subsidiary,
ICG Funding,  LLC, a Delaware  limited  liability  company,  completed a private
placement of $132.25 million of Exchangeable Limited Liability Company Preferred
Securities (the "6 3/4% Preferred Securities").  The 6 3/4% Preferred Securities
are mandatorily  redeemable  November 15, 2009 at the liquidation  preference of

option,  redeem the 6 3/4% Preferred Securities at any time on or after November
18,  2000.  Prior to that time,  ICG  Funding  may  redeem the 6 3/4%  Preferred
Securities  if the current  market  value of Common  Stock equals or exceeds the
exchange price,  for at least 20 days of any consecutive  30-day trading period,
by 170% prior to November  16,  1998;  by 160% from  November  16, 1998  through
November 15, 1999; and by 150% from November 16, 1999 through November 15, 2000.
The 6 3/4%  Preferred  Securities and the Common Stock issuable upon exchange of
such securities have been registered under the Securities Act.

     In February 1998, the Company raised proceeds,  net of underwriting  costs,
of  approximately  $291.6 million from the sale of 10% Senior Discount Notes due
2008 (the "10% Notes") of ICG Services,  Inc., a Delaware  corporation and newly
formed,  wholly owned,  unrestricted  subsidiary of ICG ("ICG  Services").  Cash
interest on the 10% Notes accrues at 10% per annum  beginning  February 15, 2003
and is payable each February 15 and August 15,  commencing  August 15, 2003. The
10% Notes will be redeemable at the option of ICG Services, in whole or in part,
on or after  February  15,  2003.  ICG Services is obligated to register the 10%
Notes under the Securities Act.

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

Telecom Services

     The Company  operates  local  exchange  networks in the  following  markets
within  its four  regional  clusters:  California  (Sacramento,  San  Diego  and
portions of the Los  Angeles and San  Francisco  metropolitan  areas);  Colorado
(Denver,  Colorado Springs and Boulder); Ohio (Akron,  Cleveland,  Columbus, and
Dayton) and the Southeast (Birmingham,  Charlotte,  Louisville,  and Nashville).
The Company  plans to build a network in Atlanta,  Georgia in  conjunction  with
Southern.  Through  its  strategic  alliance  with CSW,  the Company is offering
services in Austin, Corpus Christi,  Dallas,  Houston and San Antonio, Texas and
other selected areas of Texas, and may offer services in Arkansas, Louisiana and
Oklahoma in the future. See "-Recent Developments." The Company will continue to
expand  its  network  through  construction,  leased  facilities  and  strategic
alliances and through acquisitions.  The Company's operating networks have grown
from 627 fiber  route miles at the end of fiscal 1995 to 3,043 fiber route miles
as  of  December  31,  1997.   Telecom   Services  revenue  has  increased  from
approximately $32.3 million for fiscal 1995 to approximately  $177.7 million for
fiscal 1997.

     The Company's new subsidiary, NETCOM, is a leading provider of high quality
Internet  solutions to individuals and small and medium-sized  businesses in the
United  States and also  provides  the same high quality  Internet  solutions in
Canada  and the United  Kingdom.  NETCOM  offers a broad  spectrum  of  Internet
solutions designed to enhance customer  productivity through the integration and
application of technologies by providing a  comprehensive  software  platform to
interface with the Web, premium quality Internet access and support services and
on-line tools to automate Web site  creation and  development.  These  offerings
have led to significant  growth, with revenue increasing from approximately $2.4
million for 1993 to  approximately  $160.7  million for the calendar  year ended
December  31,  1997.  In January  1997,  NETCOM  announced  plans to migrate its
customer focus away from high volume,  low margin  consumer  customers to higher
margin products for small and medium-sized business customers.

Strategy

     The  Company's  objective  is to be a  premier  provider  of  high  quality
communications  services  to  its  targeted  business,   carrier  and  end  user
customers. The key elements of this strategy are:

     Increase  Revenue  and Margins  through  Bundled  Services to Business  End
Users. The Company  believes that customers are increasingly  demanding a broad,
full service  approach to  providing  telecommunications  services.  By offering
integrated  technology-based  communications solutions,  management believes the
Company     will    be    better     able    to    capture     business     from
telecommunications-intensive commercial accounts. To this end, the Company plans
to  complement  its  competitive  local  and  long  distance  telecommunications
offerings  with its recently  announced  IP  telephony  service and the Internet
products  developed by NETCOM,  and cross-market these combined products through
ICG's  direct  sales  force.  Additionally,   NETCOM  intends  to  market  ICG's
telecommunications products to its small and medium-sized business customer base
over the Internet. Management believes a targeted business end user strategy can
better leverage ICG's network footprint and telecommunications investment.

                                       10


     Concentrate  Networks in Regional  Clusters.  The Company  believes that by
focusing on regional  clusters it will be able to more  effectively  service its
customers'  needs and efficiently  market,  operate and control its networks and
expanded  service  offerings.  As a result,  the  Company has  concentrated  its
networks in regional  clusters serving major  metropolitan  areas in California,
Colorado, Ohio and the Southeast. The Company is expanding its network footprint
to include  certain  cities in Texas  through a strategic  alliance with CSW and
intends to further  expand its network  footprint  to include  Atlanta,  Georgia
through its agreement with Southern. In addition,  NETCOM may be able to realize
extensive  cost  synergies  by focusing  future  growth  within  ICG's  existing
footprint.  For example,  a  significant  portion of NETCOM's  customer  base is
located in California.  To the extent  feasible,  NETCOM will route its Internet
traffic over ICG's California  network.  NETCOM plans to continue to operate and
grow its business in the United States outside of ICG's network footprint and in
Canada and the United Kingdom. See "-Recent Developments."

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

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

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

Telecom Services Networks

     The  Company's  networks are  generally  comprised  of fiber optic  cables,
switching facilities,  advanced electronics,  transmission equipment and related
wiring and equipment.  The Company  typically designs a ring architecture with a
view  toward  making the network  accessible  to the  largest  concentration  of
telecommunication intensive businesses in a given market.
<PAGE>
                                       11


     The Company's  networks are generally  configured in redundant  synchronous
optical  network  ("SONET")  rings that  offer the  advantage  of  uninterrupted
service in the event of a fiber cut or equipment  failure,  resulting in limited
outages and increased  network  reliability.  The Company  generally markets its
services at prices below those charged by the ILEC.  Management  believes  these
factors combine to create a more reliable and cost effective alternative to ILEC
networks and services.

     The Company's  networks are constructed to access long distance carriers as
well as  areas of  significant  end user  telecommunications  traffic  in a cost
efficient manner. The construction period of a new network varies depending upon
the scope of the  activities,  such as the number of backbone  route miles to be
installed,  the initial  number of  buildings  targeted  for  connection  to the
network  backbone  and the general  deployment  of the  network  infrastructure.
Construction is planned to allow revenue-generating operations to commence prior
to the completion of the entire network backbone.  When constructing and relying
principally on its own facilities, the Company has experienced a period of 12 to
18 months  from  initial  design of a network  to  revenue  generation  for such
network.  Based upon its experience of using ILEC  facilities to provide initial
customer service and the Company's  agreements to use utilities' existing fiber,
the  Company  has  experienced  revenue  generation  within  nine  months  after
commencing  network  design.  After  installing  the initial  network  backbone,
extensions  to  additional  buildings  and  expansions  to  other  regions  of a
metropolitan  area  are  evaluated,  based on  detailed  assessments  of  market
potential.  The Company is currently  expanding all of its existing  networks to
reduce its reliance on the ILECs and evaluating development of new networks both
inside and outside its existing regional clusters.

     The Company's network  monitoring center in Denver monitors and manages the
Company's transport networks and provides high-level monitoring of the Company's
local  exchange  switches.  Additionally,  the  Company  contracts  with  Lucent
Technologies,  Inc. for detailed  performance  monitoring of its local  exchange
switches.  Centralized  electronic  monitoring  and  control  of  the  Company's
networks allows the Company to avoid  duplication of this function in each city,
thereby reducing costs.

     Switched services involve the transmission of voice,  video or data to long
distance carrier-specified or end user-specified termination sites. By contrast,
the special  access  services  provided by the Company and other CLECs involve a
fixed  communications link or "pipe," usually between an end user and a specific
long  distance   carrier's  point  of  presence  ("POP").   With  a  switch  and
interconnection to various carriers' networks, it is possible for the Company to
direct a long distance  carrier's  traffic to any end user regardless of whether
the end user is physically  connected to the Company's  owned or leased network.
In  addition,  a switch is required in order for the Company to provide the full
range  of local  telephone  services.  The  Company  is  marketing  and  selling
competitive  local dial tone  services  in  California,  Colorado,  Ohio and the
Southeast. See "-Regulation-State Regulation."

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

Services

     The Company's  competitive local exchange services include local dial tone,
long  distance,  data  services,  special  access and  interstate and intrastate
switched access services.  Competitive local dial tone services consist of basic
local  exchange  lines and trunks for business,  related line features  (such as
voice mail, Direct Inward Dialing (DID),  hunting and custom calling  features),
local  calling,  and  intraLATA,  also called local toll,  calling.  The Company
believes that having a full  complement of  communications  services,  including
local and long distance  services,  will  strengthen its overall market position
and help the Company to better  penetrate the local  exchange  marketplace.  The
Company has also developed long distance  services,  including calling and debit
cards, to complement its local exchange services family of products. The Company
recently  announced plans to offer a bundled service of local, long distance and
data services,  including  Internet  services,  delivered over a T-1 connection.
This service will be offered primarily to ICG's larger business customers.

     The Company announced its initial offering of long distance services in May
1997. The target customers for such services are the Company's  existing and end
user customers.  The Company's existing switches have facilitated the entry into
this  business  and reduced its cost of  obtaining  long  distance  transmission
capacity.  However,  the Company has been  reliant on other  carriers to provide
transmission and termination of long distance  traffic.  Therefore,  the Company
has  entered  into   transmission   agreements,   which  typically  provide  for
transmission on a per minute basis,  with long distance carriers to fulfill such
needs.  To reduce its cost of  services,  the Company  may lease  point-to-point
circuits on a monthly or longer term fixed cost basis where it anticipates  high
traffic volume.

     The Company recently announced its plans to offer IP long distance services
priced as low as 5.9 cents per  minute in 166  markets  by the end of 1998.  The
Company plans to carry the IP traffic over  NETCOM's  data backbone  network and
terminate a large  portion of the traffic  via  NETCOM's  238 POPs in the United
States,  thereby  eliminating  terminating  access charges.  If a call cannot be
terminated over ICG's  facilities,  it will be billed at a rate of 7.6 cents per
minute.  The Company  expects to begin  offering this service  during the second
quarter of 1998,  initially  targeting  NETCOM's  existing customer base of over
500,000 customers. The Company plans to market this product via the Internet and
through the Company's inbound telemarketing center.

     The Company  also  announced  that it will offer DSL  services  with speeds
ranging from 144kbps to 9mbps to offer its customers high-speed Internet access.
The Company plans to lease unbundled local loops from the ILEC in the respective
market  and  install  its DSL  equipment  in the  ILEC  central  office  and the
customer's  premises.  This  service  will be  offered  primarily  to the  small
business  and  work-at-home  markets,  which  historically  have  been  a  large
percentage of NETCOM's customer base.

                                       13


     To  complement  its  telecommunications  services  offerings,  the  Company
announced its initial  offering of data  communications  services in California,
Colorado and Ohio during the first quarter of 1997. These services  targeted the
Company's   existing  customers  and  other  businesses  with  substantial  data
communications  requirements.  Although to date,  the Company has not  generated
substantial revenue from such services, the Company expects that its new service
offerings,  including its IP telephony strategy and DSL technology, and NETCOM's
extensive  experience  providing  data  transmission  services,  will  allow the
Company to  significantly  enhance its presence  within the data  communications
market during fiscal 1998.

     Private line services are generally used to connect the separate  locations
of a single  business  outside of local  access  and  transport  area  ("LATA").
Special  access  services are generally  used to connect end user customers to a
long distance telephone carrier's facilities, to connect long distance carrier's
facilities to the local  telephone  company's  central  offices,  and to connect
different  facilities  of the  same  long  distance  carrier  or  facilities  of
different long distance carriers all within the same local calling area or LATA.
As part of its initial "carrier's  carrier"  strategy,  the Company targeted the
transport  between long  distance  company  facilities  and the local  telephone
company  central  offices,  and,  for high  volume  customers,  between the long
distance  company and the end user customer's  office.  In order to leverage its
significant network investment, the Company has markets its services directly to
end user business customers.

     The Company's  interstate and intrastate  switched access services  include
the  transport  and  switching  of calls  between  the long  distance  carrier's
facilities and either the local telephone  company central offices or end users.
By performing the switching  services,  the Company can reduce the long distance
carriers' local access costs,  which constitute  their major operating  expense.
The Company has  experienced  negative  operating  margins from the provision of
wholesale  switched services because it relies on ILEC networks to terminate and
originate customers' switched traffic. The Company has recently raised prices on
its  wholesale  switched  services  product in order to improve  margins  and is
de-emphasizing  its wholesale  switched services to free up switch port capacity
for its higher margin dial tone product. In addition,  as the Company provides a
greater  portion  of the  local  segment  of a  call,  the  Company  expects  to
experience improved operating margins.

     The  Company's  Signaling  System  7  ("SS7")  services  provide  signaling
connections between long distance and local exchange carriers,  and between long
distance carriers' networks.  SS7, known as look-ahead routing, is used by local
exchange  companies,  long distance  carriers,  wireless  carriers and others to
signal between network  elements,  creating  faster call set-up,  resulting in a
more  efficient  use of network  resources.  SS7 is now the standard  method for
telecommunications signaling worldwide. The Company has deployed signal transfer
points ("STPs") throughout its networks to efficiently route SS7 data across the
United States.  SS7 is also the enabling  technology  for advanced  intelligence
network platforms, a set of services and signaling options that carriers can use
to create new services or customer options.  Carriers purchase  connections into
the  Company's  SS7 network,  and also purchase  connections  to other  carriers
(local and long distance) on a monthly recurring basis.
<PAGE>
                                       14


     In August  1996,  the Company  acquired  the SS7  business of Pace  Network
Services, Inc., a division of Pace Alternative Communications,  Inc. The Company
has also developed a nationwide SS7 service with Southern New England  Telephone
("SNET"),  one of the nation's ten largest local exchange carriers.  The Company
believes  that,  together  with  SNET,  it is  one of  the  largest  independent
suppliers of SS7  services.  The  Company's  STPs are  integrated  with two SNET
"gateway" STPs in Connecticut.

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

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

     NETCOM customers can quickly register using NETCOMplete software, available
for both Windows and Macintosh  platforms via compact disk,  and set up a NETCOM
account by following a sequence of simple,  on-screen steps. All of the software
needed to  connect  and access  the  Internet  is  automatically  installed  and
configured, eliminating the need for complex set up procedures. NETCOMplete also
provides an  easy-to-use  interface as well as software  from  leading  industry
participants,  bookmark managers, off-line browsers and additional software that
enhances  a  customer's  Internet  experience.  Revenue  from  dial-up  services
increased  from $102.9  million for the calendar year ended December 31, 1996 to
$133.7  million for the calendar  year ended  December  31,  1997,  representing
approximately  85% and 83%,  respectively,  of  total  NETCOM  revenue  for such
periods.

     Direct Access Services.  NETCOM offers a full suite of high-speed dedicated
Internet   connection   and  service   products  which  provide  its  small  and
medium-sized business customers with direct access to the full range of Internet
applications.  These  Internet  services are offered to  businesses  over leased
lines at various speeds,  including 56 Kbps, T-1 and T-3 levels,  depending upon
the  customer's  needs.  Through its direct access  product line,  NETCOM offers
Internet access services  including domain name and Internet  protocol  address,
router configurations, on-line usage statistics and security consultation. There
are  generally no usage  charges for any of NETCOM's  dedicated  customers,  and
E-mail service and USENET news feed are provided at no additional charge. Direct
network  connection  requires  the  customer to obtain a leased line from ICG or
another local telephone company. NETCOM provides an Internet connection based on
frame relay technology provided by local telephone carriers. Revenue from direct
access  services  increased  from  $16.3  million  for the  calendar  year ended
December  31, 1996 to $19.5  million for the  calendar  year ended  December 31,
1997,  representing  approximately  14% and 12%,  respectively,  of total NETCOM
revenue for such periods.

                                       15


     Web Site Hosting  Services.  NETCOM offers Web site hosting services to its
small and medium-sized  business  customers as well as to individuals.  Web site
hosting  services  include  client  domain name  registration,  hosting and site
maintenance.  Services  provided  are fully  scalable  but  would,  in a typical
package,  include  domain  name  registration,  10 E-mail  addresses,  access to
NETCOM's on-line  business center,  CGI scripting (which enables visitors to the
Web site to leave their names and addresses),  weekly back-up service,  50 Mb of
data  storage,  1,000  Mb per  month  of data  transfers,  traffic  logs and Web
statistics  and premium  service and technology  support.  Revenue from Web site
hosting  services  increased  from $1.3  million  for the  calendar  year  ended
December 31, 1996 to $6.3 million for the calendar year ended December 31, 1997,
representing approximately 1% and 4%, respectively,  of total NETCOM revenue for
such periods.

     Value-Added  Services.  As part of its dial-up,  direct access and Web site
hosting services,  NETCOM offers its small and medium-sized  business  customers
value-added  business  connectivity  solutions package designed to address their
needs of increased security, reliability, access speed and customer service. The
Company  believes that  businesses  are willing to pay premium  prices for these
premium services.  One such feature is Automatic  Reconnect which  automatically
re-routes customers' traffic to an alternate Integrated Services Digital Network
("ISDN")  line so that in the event of certain  kinds of  service  interruptions
customers may remain connected. In order to provide a secure, private connection
among multiple specific  locations,  NETCOM's  SecureConnect  product performs a
security  assessment and then implements,  monitors and troubleshoots a flexible
security  solution to provide  secure  communication  between  central  offices,
branch offices and off-site employees without  jeopardizing the integrity of the
internal network.  Another  value-added service NETCOM offers is 24 hours a day,
seven  days a week  support.  For  larger  customers,  NETCOM  offers  flexible,
high-speed dedicated line service that is scalable to grow as traffic increases.
Other value-added  services offered include password  protected Web sites, usage
statistics, anti-virus software and additional domain names.

     Zycom. The Company owns a 70% interest in Zycom Corporation ("Zycom") which
operates  an  800/888/900  number  service  bureau and a switch  platform in the
United  States  supplying  information  providers and  commercial  accounts with
audiotext and customer support services.

Industry

     The Company operates in the local telephone  services market as an ICP. The
Company  is  competing  in the  local,  long  distance  and data  communications
markets,  and subsequent to January 21, 1998, the Internet  services market,  to
provide  "full  service"  to its end user and  carrier  customers.  The  Company
believes it can maximize  revenue and profit  opportunities  by  leveraging  its
extensive network  facilities in providing multiple  communications  services to
its customers.

                                       16


     Local   telephone   service   competition   was   made   possible   by  the
Telecommunications  Act and by deregulatory actions at the state level. Prior to
passage of the  Telecommunications  Act,  firms like the Company were  generally
confined to providing  private line and special  access  services.  These firms,
including  the Company,  installed  fiber optic cable  connecting  long distance
telephone  carriers'  POPs  within  a  metropolitan  area  and,  in some  cases,
connecting end users (primarily  large businesses and government  entities) with
long distance carrier POPs. The greater capacity and economies of scale inherent
in fiber optic cable enabled  competitive  access  providers to offer  customers
less expensive and higher quality  special access and private line services than
the ILECs.


     The  Telecommunications  Act,  subsequent  FCC  decisions  and  many  state
legislative  and  regulatory   initiatives   have   substantially   changed  the
telecommunications  regulatory  environment in the United  States.  Due to these
regulatory  changes,  CLECs are now  legally  able to offer  all  communications
services,  including local dial tone and all interstate and intrastate  switched
services, effectively opening up the local telephone market to full competition.
Because of these changes in state and federal  regulations,  CLECs have expanded
their  services from providing  competitive  access and private line services to
providing all local exchange  services to become true  competitors to the ILECs.
See "-Regulation."

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

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

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

Network Services

     Through  the   Company's   wholly   owned   subsidiary,   ICG  Fiber  Optic
Technologies,   Inc.  ("FOTI"),  the  Company  supplies  information  technology
services  and  selected  networking   products,   focusing  on  network  design,
installation,  maintenance  and  support  for a variety of end users,  including
Fortune 1000 firms and other large businesses and telecommunications  companies.
Revenue from Network Services was approximately $65.6 million for fiscal 1997.

<PAGE>
                                       17



     The Company provides network infrastructures, systems and support services,
including  the  design,  engineering  and  installation  of local  and wide area
networks,  ("LANs/WANs")  for its  customers.  These  networks  (within end user
offices, buildings or campuses) may include fiber optic,  twisted-pair,  coaxial
and other  network  technologies.  The Company  specializes  in turnkey  network
installations   including   cabling  and  electronics   that  address   specific
environments.  The Company also provides  professional network support services.
These  services  include  network  move,  add and change  services  and  ongoing
maintenance  and  support  services.  Network  Services  revenue is  expected to
constitute a smaller portion of the Company's future revenue as Telecom Services
revenue increases.

     The Company offers these network  integration and support  services through
offices located within four regions.  The regional  headquarters  are located in
Dallas, Denver, Portland (Oregon) and San Francisco.

Satellite Services

     The Company's  Satellite  Services  operations  provide satellite voice and
data services to major cruise lines,  commercial  shipping vessels,  yachts, the
U.S. Navy and offshore oil platforms.  The Company also owns a teleport facility
which provides international voice and data transmission  services.  Revenue for
Satellite Services  operations was approximately  $30.0 million for fiscal 1997.
The Company intends to dispose of its Satellite  Services  operations to better
focus its efforts on its core Telecom services unit, although it has not entered
into a formal arrangement for such disposition.

     MTN.  In January  1995,  the  Company  and an  unaffiliated  entity  formed
Maritime  Telecommunications Network, Inc. ("MTN") which purchased the assets of
a business providing digital wireless  communications  through satellites to the
maritime cruise industry, U.S. Navy vessels and offshore oil platforms utilizing
an experimental  radio frequency license issued by the FCC. MTN provides private
communications networks to various cruise lines allowing for the transmission of
data  communications and allowing  passengers to make calls from their cabins to
anywhere in the world. MTN additionally provides its communications  services to
seismic  vessels,  to  commercial  shipping  vessels  and to the  U.S.  Navy  in
conjunction  with a major  long  distance  provider,  which  serves  as the long
distance carrier, while MTN provides the shipboard communications equipment. The
Company believes that the radio spectrum employed under its experimental license
and a recent grant of Special  Temporary  Authority  ("STA"),  which uses C-band
radio frequencies,  enables it to provide a higher quality maritime service than
is available through the radio frequencies currently allocated to other maritime
service providers.
<PAGE>
                                       18


     In  April  1996,  the FCC  issued  a waiver  allowing  MTN to  apply  for a
permanent FCC license to utilize the same C-band  frequencies  as are being used
under the  experimental  license.  MTN's  application is pending.  The Company's
experimental  license was renewed for an additional  two-year period on November
21, 1997.  Additionally,  in January 1997,  the FCC granted an STA which enables
MTN to conduct operations as proposed in the pending application for a permanent
license,  for six-month periods. MTN filed for six-month renewals for the STA on
July 25, 1997 and January 27, 1998 and the Company has received verbal grants of
the  six-month  extensions.  There can be no assurance  that the Company will be
granted a permanent  license,  that the  experimental  license and STA currently
being used will  continue  to be renewed  for future  terms or that any  license
granted by the FCC will not require substantial  payments from the Company.  See
"-Regulation."

     MCN. In March 1996, the Company acquired a 90% equity interest in MarineSat
Communications  Network,  Inc. ("MCN") (formally Maritime Cellular  TeleNetwork,
Inc.), a  Florida-based  provider of cellular and satellite  communications  for
commercial ships,  private vessels and land-based mobile units. This acquisition
expands the Company's  business from C-band satellite  services for cruise ships
and naval vessels to cover  land-based  units and smaller ships.  In April 1997,
the  Company  received  the  remaining  10% equity  interest in MCN as a partial
consideration for the sale of another of its subsidiaries.

     Nova-Net. In May 1994, the Company acquired Nova-Net  Communications,  Inc.
("Nova-Net"), which provides private data networks utilizing very small aperture
terminals  ("VSATs") and  specializes  in data  collection and in monitoring and
control  of  customer   production  and   transmission   facilities  in  various
industries,   including   oil  and  gas,   electric  and  water   utilities  and
environmental  monitoring  industries.  Nova-Net  designs,  builds  and  manages
private data  networks  that enable a variety of companies to transmit  critical
sensor and flow  readings  to key  monitoring  points from  multiple  locations.
Nova-Net  manages networks 24 hours a day, seven days a week through its network
control center in Englewood, Colorado.

     Teleport.  The  teleport  in Holmdel,  New Jersey,  acquired as part of the
Company's  acquisition  of  MTN,  is  located  20  miles  south  of  Newark  and
specializes in international digital voice and data communications services with
full fiber  interconnect to the local telephone  company  facilities in New York
City.  Teleport services are also provided to the maritime  industry,  including
support of the  Company's  cruise  ship,  U.S.  Navy and  offshore  oil platform
telephone  and data  services  business.  In addition,  the Company  markets the
resale of services from the four teleports it sold in 1996.

Customers And Marketing

     The Company's  primary  marketing  strategies  for Telecom  Services are to
offer  a broad  range  of  local  and  long  distance  communications  services,
including  data   communications,   to  the  Company's   business  customers  at
cost-effective  rates.  Wholesale  customers  typically  re-market the Company's
services to the  retailer's  end user,  under the  retailer's  brand  name.  The
Company markets its services in regional clusters, which it believes is the most
effective and efficient way to penetrate its markets.

<PAGE>
                                       19



     The Company markets its Telecom  Services  products through direct sales to
end users and wholesale accounts,  and direct mail, to a limited extent. Telecom
Services  revenue from major long distance  carriers and  resellers  constituted
approximately 78%, 71%, 69% and 64% of the Company's Telecom Services revenue in
fiscal 1995 and 1996, the three-month  period ended December 31, 1996 and fiscal
1997,  respectively.  The balance of the Company's  Telecom Services revenue was
derived  from end users.  The Company  anticipates  revenue  from end users will
increase in the future as it continues to expand its bundled service  offerings,
increases its sales and marketing teams and focuses more on the end user segment
of the  market.  In support of this  strategy,  the  Company  has  substantially
increased its direct sales and marketing  staff.  The Company's  sales force has
grown  from  143  people  at  December  31,  1996 to  approximately  356  people
(including sales management, technical sales support and administrative support)
at December 31, 1997.  Telecom service  agreements with its customers  typically
provide  for terms of one to five  years,  fixed  prices  and early  termination
penalties.

     The Company has  telecommunications  sales offices in: Irvine, Los Angeles,
Oakland,  Sacramento  and San Diego,  California;  Denver and Colorado  Springs,
Colorado; Cleveland, Columbus and Dayton, Ohio; Birmingham, Alabama; Louisville,
Kentucky;  Charlotte,  North Carolina; and Nashville,  Tennessee.  The Company's
marketing staff is located in Denver, Colorado.

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

     The Company markets its network systems  integration  products and services
through a direct sales force located in the Rocky Mountains,  Pacific Northwest,
Texas  and  California  regions.  The  Company  also  has  entered  into  resale
agreements with manufacturers of network integration products and services.

     The Company offers satellite  private line  transmission  services from its
teleport to business customers that can benefit from the Company's international
and domestic transmission capabilities.  The Company also markets voice and data
communications  to the maritime  industry,  including  cruise  ships,  U.S. Navy
vessels,  commercial vessels,  private yachts, offshore oil platforms and mobile
land-based units.

Competition

     The Company operates in an increasingly  competitive  environment dominated
by the ILECs,  mainly the Regional Bell  Operating  Companies  ("RBOCs") and GTE
which are among the  Company's  current  competitors.  Also  included  among the
Company's  current  competitors  are other ILECs,  other CLECs,  network systems
integration  service  providers,  microwave  and  satellite  service  providers,
teleport operators,  wireless telecommunications  providers and private networks
built by large end users.  Potential  competitors  (using  similar or  different
technologies) include cable television companies, utilities, ILECs outside their
current local service  areas,  and the local access  operations of long distance
carriers.  Consolidation  of  telecommunications  companies,  including  mergers
<PAGE>
                                       20



between certain of the RBOCs,  and the formation of strategic  alliances  within
the telecommunications industry, as well as the development of new technologies,
could give rise to  increased  competition.  One of the primary  purposes of the
Telecommunications  Act is to  promote  competition,  particularly  in the local
telephone  market.  Since  enactment  of  the  Telecommunications  Act,  several
telecommunications  companies have  indicated  their  intention to  aggressively
expand  their  ability  to  address  many  segments  of  the  telecommunications
industry,  including  segments in which the Company  participates and expects to
participate. For example, AT&T Corp. ("AT&T"), MCI Communications Corp. ("MCI"),
Time  Warner  Communications,  Inc.,  Texas  Utilities  Company  and other large
companies are entering the local markets,  as  competitors of the Company.  This
may result in more  participants  than can  ultimately  be successful in a given
market.

     Telecom   Services.   The  bases  of  competition   in  competitive   local
telecommunications   services  are  generally   price,   service,   reliability,
transmission speed and availability.  The Company believes that its expertise in
developing and operating highly reliable,  advanced digital networks which offer
substantial  transmission  capacity at competitive prices enables the Company to
compete effectively against the ILECs and other CLECs.

     In every market in which the Company operates telecom service networks, the
ILECs (which are the historical  monopoly providers of local telephone services)
are the primary  competitors.  The ILECs have  long-standing  relationships with
their  customers  and provide  those  customers  with various  transmission  and
switching  services.  The ILECs also have the potential to subsidize  access and
switched  services  with revenue from a variety of businesses  and  historically
have benefited from certain state and federal  regulations that have favored the
ILECs over the Company.  In certain  markets where the Company  operates,  other
CLECs also operate or have  announced  plans to enter the market.  Some of those
CLECs are affiliated  with major long distance  companies.  Current  competitors
also  include  network  systems   integration   services   providers,   wireless
telecommunications  providers  and  private  networks  built by large end users.
Additional  competition may emerge from cable television  operators and electric
utilities.  Many of the Company's actual and potential  competitors have greater
financial, technical and marketing resources than the Company.
<PAGE>
                                       21


     The  Company's  networks  compete most  directly with the RBOCs and GTE. In
general,  the  provision  of  interstate  access  services by the RBOCs and GTE,
including the rates charged for such services,  is regulated by the FCC, and the
provision of intrastate  access and local services,  including the rates charged
for such services, is regulated by the individual state regulatory  commissions.
See "-Regulation." In the past, FCC policies have constrained the ability of the
RBOCs and GTE to decrease their prices for interstate access services,  based on
their status as dominant  carriers.  Although FCC regulatory  approval for price
reductions  (beyond  certain  parameters)  still must be  obtained,  the FCC has
allowed all recently  proposed  access  reductions  to become  effective and has
granted the RBOCs  flexibility in pricing their interstate  access services on a
central office by central  office basis.  This pricing  flexibility  resulted in
certain RBOCs lowering their prices in high density zones, the probable arena of
competition  with the Company.  In addition,  the FCC has granted waivers of its
access charge pricing rules to the RBOCs to allow them to further reduce certain
access prices.  In May 1997, the FCC released a decision  amending and reforming
many of its access charge rules and sought further comment on additional issues.
In addition,  the FCC  released a separate  decision in May 1997  reforming  its
rules  on  universal  service  subsidies  pursuant  to the  requirements  of the
Telecommunications  Act. As a whole,  the FCC's  decision  reforming  the access
charge rules is not likely to have a material  adverse  impact on the  Company's
access  services  offerings,  because the  decision  required  relatively  small
decreases in total access prices  charged by the ILECs.  The major impact of the
FCC's  decision  was to shift  access cost  recovery by the ILECs to  flat-based
charges from usage-sensitive  (minute-of-use) charges. The continued lowering of
access  rates  and  increased  pricing  flexibility  for the  RBOCs  and GTE may
adversely affect the Company's ability to compete for certain  services.  If the
RBOCs and GTE continue to lower access rates,  there would be downward  pressure
on certain  special  access and switched  access rates  charged by CLECs,  which
pressure may adversely affect the Company's profitability. See "-Regulation." In
addition,  the  Telecommunications  Act and its implementation by the states and
the FCC  allows  the RBOCs to seek  permission  to  provide  a broader  range of
services  and likely will enable the RBOCs and GTE to more  effectively  compete
against long distance  carriers,  which are the Company's  primary customers for
telecom services.

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

     Network  Services.  The bases of competition in the network services market
are primarily technological capability and experience,  value-added services and
price. In this market, the Company competes with a variety of local and regional
system integrators.

     Satellite Services. In the delivery of domestic and international satellite
services,  the  Company  competes  with  other  full  service  teleports  in the
northeast  region of the United States.  The bases of competition  are primarily
reliability,  price and transmission  quality.  Most of the Company's  satellite
competitors  focus  on  the  domestic  video  market.  Competition  is  expected
principally from a number of domestic and foreign  telecommunications  carriers,
many of which have substantially  greater financial and other resources than the
Company. In the maritime  telecommunications market, MTN competes primarily with
COMSAT Corporation ("COMSAT") in providing similar telecommunications  services.
COMSAT has FCC licenses  that are similar to MTN's,  it owns its own  satellites
and it is the sole U.S. point of control for access to Intelsat satellites.

                                       22


     Internet  Services.  Beginning  January 21,  1998,  the Company  also faces
competition  within the Internet services market. The market for Internet access
and related services is highly competitive. There are no substantial barriers to
entry and the Company anticipates that competition will continue to intensify as
the use of the Internet grows.  The tremendous  growth and potential market size
of the  Internet  access  market has  attracted  many new  start-ups  as well as
existing   businesses  from  different   industries.   Current  and  prospective
competitors  include,  in addition to other  national,  regional and local ISPs,
long distance and local exchange telecommunications companies, cable television,
direct  broadcast  satellite,  wireless  communications  providers,  and on-line
service providers.

Regulation

     The Company's services are subject to significant federal,  state and local
regulation.  The Company operates in an industry that is undergoing  substantial
change as a result of the passage of the Telecommunications Act.

     The  Telecommunications  Act opened the local and long distance  markets to
additional competition and changed the division of oversight between federal and
state regulators.  Under previous law, state regulators had authority over those
services that  originated and  terminated  within the state  ("intrastate")  and
federal  regulators had  jurisdiction  over services that originated  within one
state  and  terminated  in  another  state  ("interstate").  State  and  federal
regulators  now  share  responsibility  to  some  extent  for  implementing  and
enforcing   the   pro-competitive   policies   and   the   provisions   for  the
Telecommunications Act.

     The Telecommunications Act generally requires ILECs to negotiate agreements
to provide  interconnection  and  nondiscriminatory  access to their networks on
more favorable terms than were previously  available in the past. However,  such
new  agreements  are  subject to  negotiations  with each ILEC which may involve
considerable  delays and may not necessarily be obtained on terms and conditions
that are desirable to the Company.  In such instances,  the Company may petition
the proper state regulatory agency to arbitrate disputed issues. Ultimately, the
terms of an arbitrated  agreement  are subject to review by the federal  courts.
There can be no assurance that the Company will be able to negotiate  acceptable
interconnection agreements or that, if state regulatory authorities impose terms
and conditions on the parties in  arbitration,  such terms will be acceptable to
the Company.

     On August 8, 1996, in two separate  decisions (the "First Report and Order"
and  the  "Second  Report  and  Order"),  the FCC  adopted  rules  and  policies
implementing the local competition provisions of the Telecommunications Act. The
FCC,  among  other  things,  adopted  national  guidelines  with  respect to the
unbundling of ILECs' network elements,  resale of ILEC services,  the pricing of
interconnection  services and unbundled  elements,  and other local  competition
issues. Numerous parties appealed both of the FCC's orders to the Eighth Circuit
Court, and in October 1996 the Eighth Circuit Court stayed the implementation of
many of the rules in the First Report and Order.  On July 18,  1997,  the Eighth
Circuit  Court  issued a decision  on the First  Report and Order  which  upheld
certain  of the  FCC's  rules and  reversed  the  FCC's  rules on other  issues,
including the pricing rules. On August 22, 1997, the Eighth Circuit Court issued
its decision on the Second Report and Order,  which  concluded  that the FCC had
exceeded its jurisdiction in issuing certain rules on dialing parity.
<PAGE>
                                       23


     Separate  petitions  for  rehearing of the July 18 decision were filed with
the Eighth  Circuit Court by a group of  interexchange  carriers,  two groups of
ILECs and a group of CLECs.  On  October  14,  1997,  the Eighth  Circuit  Court
granted the ILEC petitions for rehearing, and denied the CLEC and IXC petitions.
The Court's decision on rehearing  vacated an additional FCC rule that addressed
the ability of new  entrants to purchase  ILEC  network  elements at  cost-based
rates on a bundled rather than an unbundled basis.

     The FCC and other parties filed petitions for certiorari  seeking review by
the U.S.  Supreme Court of the Eighth  Circuit  Court's  decision,  and the U.S.
Supreme Court has granted the petitions for  certiorari and agreed to review the
case. It is  anticipated  that the case will be argued  before the U.S.  Supreme
Court in the fall of 1998,  with a final  decision  issued in 1999.  The  Eighth
Circuit  Court's  ruling  remains  in effect  pending  final  action by the U.S.
Supreme Court.

     On December 31, 1997,  the United  States  District  Court for the Northern
District  of Texas,  in a case  brought by SBC  Communications,  Inc.,  issued a
decision holding that Sections 271 through 275 of the Telecommunications Act are
unconstitutional.  The decision addresses the restrictions contained in Sections
271  through 275 of the  Telecommunications  Act on the lines of  businesses  in
which the RBOCs may engage, including establishing the conditions that the RBOCs
must satisfy before they may provide interLATA long distance  telecommunications
services in their local telephone service areas. On February 11, 1998, a stay of
the decision  was issued by the United  States  District  Court for the Northern
District  of Texas,  which  stay will  remain  in effect  pending  appeal of the
decision by the Fifth Circuit Court of Appeals.

     Federal  Regulation.  The Company generally operates as a regulated carrier
with fewer  regulatory  obligations than the ILECs. The Company must comply with
the  requirements of the  Telecommunications  Act, such as offering service on a
non-discriminatory  basis at just  and  reasonable  rates.  The FCC  treats  the
Company as a non-dominant  carrier. The FCC has established  different levels of
regulation for dominant and non-dominant  carriers. Of domestic common carriers,
only GTE and the RBOCs are classified as dominant  carriers for the provision of
access services, and all other providers of domestic common carrier services are
classified  as  non-dominant.   Under  the  FCC's   streamlined   regulation  of
non-dominant   carriers,  the  Company  must  file  tariffs  with  the  FCC  for
international   services  on  an  ongoing  basis.  The  Company's  provision  of
international  long distance  services  requires prior  authorization by the FCC
pursuant to Section  214 of the  Telecommunications  Act,  which the Company has
obtained.   The  FCC  recently  eliminated  the  requirement  that  non-dominant
interstate  access  carriers  must file  tariffs.  The Company is not subject to
price cap or rate of return  regulation,  nor is it currently required to obtain
FCC  authorization  for the installation or operation of its fiber optic network
facilities  used for services in the United States.  The Company may install and
operate  non-radio  facilities  for  the  transmission  of  domestic  interstate
communications  without  prior FCC  authorization.  The Company's use of digital
microwave  radio  frequencies  and satellite  earth stations in connection  with
certain of its  telecommunications  services  is subject to FCC radio  frequency
licensing regulation.  See "-Federal Regulation of Microwave and Satellite Radio
Frequencies."

                                       24


     State  Regulation.  In general,  state regulatory  agencies have regulatory
jurisdiction  over the Company when Company  facilities and services are used to
provide local and other intrastate services.  Under the Telecommunications  Act,
states cannot effectively prohibit any entity from providing  telecommunications
services,  but the states continue to have general authority to set criteria for
reviewing   applications  to  provide  intrastate   services   (including  local
services).  State regulators will continue to set the requirements for providers
of local and  intrastate  services,  including  quality  of  services  criteria.
However,  state regulators can no longer allow (or require)  restrictions on the
resale of  telecommunications  services.  State regulators also can regulate the
rates charged by CLECs for  intrastate and local services and can set prices for
interconnection  by CLECs with the ILEC  networks.  The  Company's  provision of
local dial tone and intrastate switched and dedicated services are classified as
intrastate and therefore subject to state  regulation.  The Company expects that
it will offer more intrastate services as its business and product lines expand.
To  provide  intrastate  service  (particularly  local dial tone  service),  the
Company generally must obtain a Certificate of Public  Convenience and Necessity
("CPCN") from the state  regulatory  agency prior to offering  service.  In most
states,  the Company also is required to file tariffs  setting  forth the terms,
conditions  and prices for services that are  classified as  intrastate,  and to
update or amend its  tariffs as rates  change or new  products  are  added.  The
Company   may  also  be  subject  to  various   reporting   and   record-keeping
requirements.

     The Company currently holds CPCNs (or their equivalents) from the states of
Alabama,  California,  Colorado,  Florida,  Georgia,  Indiana,  Kentucky,  North
Carolina,  Ohio,  Oklahoma,  Tennessee  and Texas.  The Company has authority to
provide local and intrastate long distance services in each of these states.

     Local Government  Authorizations.  Under the Telecommunications  Act, local
authorities  retain  jurisdiction  under  applicable  state law to  control  the
Company's access to municipally owned or controlled rights of way and to require
the Company to obtain  street  opening and  construction  permits to install and
expand its fiber optic network.  In addition,  many  municipalities  require the
Company to obtain licenses or franchises (which generally have terms of 10 to 20
years) and to pay license or  franchise  fees,  often based on a  percentage  of
gross  revenue,  in order to provide  telecommunications  services,  although in
certain states including California and Colorado, such fees may be imposed under
current state law. Certain  municipalities in Colorado,  however, are continuing
to charge franchise fees pending enforcement by the Colorado courts. There is no
assurance  that  certain  cities that do not impose fees will not seek to impose
fees,  nor is there any assurance  that,  following  the  expiration of existing
franchises, fees will remain at their current levels. In many markets, the ILECs
have  been  excused  from  paying  such  franchise  fees or pay  fees  that  are
materially  lower than those  required  to be paid by the  Company for access to
public  rights  of  way.  However,  under  the  Telecommunications   Act,  while
municipalities  may  still  regulate  use of their  streets  and  rights of way,
municipalities  may  not  prohibit  or  effectively  prohibit  any  entity  from
providing any  telecommunications  services. In addition, the Telecommunications
Act  requires  that  local  governmental  authorities  treat  telecommunications
carriers in a non-discriminatory and competitively neutral manner. If any of the
Company's existing franchise or license agreements are terminated prior to their
expiration  dates or not renewed,  and the Company is forced to remove its fiber
from the streets or abandon its network in place,  such termination could have a
material adverse effect on the Company.

     Federal  Regulation of Microwave and Satellite Radio  Frequencies.  The FCC
continues to regulate  radio  frequency use by both private and common  carriers
under the  Telecommunications  Act.  Unlike common  carriers,  private  carriers
contract with select  customers to provide  services  tailored to the customer's
specific needs. The FCC does not currently regulate private carriers (other than
their use of radio  frequencies)  and has preempted  the states from  regulating
private carriers. The Company offers certain services as a private carrier.

     The Company is required to obtain authorization from the FCC for its use of
radio frequencies to provide satellite and wireless services.  The Company holds
a number of  point-to-point  microwave  radio  licenses that are used to provide
telecommunications  services in  California.  Additionally,  the Company holds a
number of satellite  earth station  licenses in connection with its operation of
satellite-based  networks.  The Company also  provides  maritime  communications
services  pursuant  to an  experimental  license  and a grant of a STA. In April
1996,  the FCC  issued a waiver  to the  Company  which may allow it to obtain a
permanent FCC license to provide these services using the same radio frequencies
currently  being used under the  experimental  license and STA.  The Company has
filed an application for a permanent license under the terms of the FCC's waiver
decision,  and the  application  is pending.  The STA was granted on January 30,
1997 and enables the Company to conduct operations  pursuant to such application
during the FCC's review.  Applications for six-month  extensions of the STA were
filed on July  25,  1997 and on  January  27,  1998  and  verbal  grants  of the
extensions  have been  issued by the FCC.  There  can be no  assurance  that the
Company will be granted a permanent license,  that the experimental  license and
STA  currently  being used will  continue to be renewed for future terms or that
any license  granted by the FCC will not require  substantial  payments from the
Company.

     Regulation  of  Internet  Services.  The  Company  is  currently  providing
Internet access services through its recently  acquired  subsidiary,  NETCOM, in
part through data transmissions over public telephone lines. These transmissions
are governed by regulatory policies establishing charges and terms for wire-line
communications.  Although  the  Company  is  not  currently  subject  to  direct
regulation by the FCC or any other  governmental  agency (other than regulations
applicable to businesses generally),  due to the increasingly  widespread use of
the Internet, it is possible that additional laws and regulations may be adopted
with respect to the  Internet,  covering  issues such as content,  user privacy,
pricing,   libel,   intellectual  property  protection  and  infringement,   and
technology export and other controls. It also is possible that the Company could
become  subject  to  regulation  by the FCC or  another  regulatory  agency as a
provider of basic  telecommunications  services.  The FCC is currently reviewing
its regulatory  positions on whether to impose common carrier  regulation on the
network  transport  and  communications  facilities  aspects of an  enhanced  or
information  service  package.  Such  changes in the  regulatory  structure  and
environment  affecting the Internet access market,  including regulatory changes
that  directly or  indirectly  affect  telecommunications  costs or increase the
likelihood of competition from the RBOCs or other telecommunications  companies,
could have an adverse effect on the Company's business.  For example, the FCC is
considering  whether  ISPs  should be  required  to pay access  charges to local
telephone  companies for each minute that  dial-access  users spend connected to
ISPs through telephone company  switches,  and is also considering  whether ISPs
should be required to make monetary  contributions to federal  universal service
funds. In addition,  some telephone companies are seeking similar relief through
state regulatory agencies. Such rules, if adopted at either the federal or state
level,  would have a material adverse effect on the Company.  The Company cannot
predict the impact, if any that future regulation or regulatory changes may have
on its business.

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

     The Company believes it is entitled to receive reciprocal compensation from
ILECs for the transport and  termination of local traffic to ISPs from customers
of the ILECs, pursuant to various interconnection  agreements.  These ILECs have
not paid most of the bills they have received from the Company and have disputed
substantially  all of these  charges,  arguing  that ISP  traffic  is not  local
traffic as defined by the various  agreements  and under state and federal  laws
and public policies.  To date, there have been favorable  rulings from 15 states
and public utilities  commissions and no unfavorable  final rulings by any state
public utilities  commission or the FCC that would indicate that calls placed by
end users to ISPs would not qualify as local  traffic  subject to the payment of
reciprocal  compensation.  While the Company  believes  that  future  regulatory
rulings on this issue will  continue to treat such calls as local,  there can be
no assurance that such future rulings will continue to be favorable.

Employees

     On December 31, 1997, the Company employed a total of 2,219  individuals on
a full time  basis.  There are 48  employees  in the  Company's  Oregon  network
systems integration services office who are represented by collective bargaining
agreements  which  expire on May 31, 1998 and  December  31,  2000.  The Company
believes that its relations with its employees are good.

ITEM 2.   PROPERTIES

     The  Company's  physical  properties  include  owned and  leased  space for
offices, storage and equipment rooms and collocation sites. Additional space may
be purchased or leased by the Company as networks are expanded. The Company owns
a 30,000  square-foot  building  located in the Denver  metropolitan  area which
houses a portion of the Company's Telecom Services business.  The Company leases
approximately  176,000 square feet of office space for operations located in the
Denver metropolitan area and approximately 262,000 square feet in other areas of
the United States.

     As of December  31,  1997,  the Company had  acquired  property for and had
partially  constructed  its new  headquarters in Englewood,  Colorado,  which is
planned to accommodate  most of the Company's  Colorado  operations.  In January
1998, the Company sold the substantially completed building to a third party and
entered into an agreement to lease back the  approximately  265,000  square foot
facility under a long-term operating lease.

ITEM 3.  LEGAL PROCEEDINGS

     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 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  various  statutory and common law
claims. 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.

     A putative  class  action  lawsuit  was filed on July 15,  1997 in Superior
Court of  California,  Orange  County,  alleging  unfair  business  practice and
related causes of action  against  NETCOM in connection  with its offers of free
trial periods and cancellation procedures and claiming damages of at least $10.0
million.  The case is in the preliminary stages, the complaint has been answered
and plaintiff has served initial requests for discovery.  NETCOM believes it has
meritorious defenses to such claims and intends to vigorously defend the action.

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

     The Company is 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.

ITEM 4.  SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

(1)  Effective  at the close of  trading  on August 2,  1996,  Holdings-Canada's
     Class A Common Shares  ceased  trading on the AMEX and the ICG Common Stock
     commenced trading on the AMEX on August 5, 1996.  Effective March 25, 1997,
     the ICG Common Stock ceased  trading on the AMEX and  commenced  trading on
     the  Nasdaq.  ICG  Common  Stock has never  traded on the VSE.  The Class A
     Common Shares traded on the VSE through March 12, 1997 and all  information
     reported  on the above  table  from  August 5, 1996 to March 12,  1997 with
     respect to the VSE relates only to the Class A Common Shares.

(2)  The Company  changed its fiscal year end to December 31 from  September 30,
     effective January 1, 1997.

     See the cover page of this Annual Report for a recent bid price and related
number of shares  outstanding of Common Stock. On March 26, 1998, there were 284
holders of record.

     The Company has never  declared or paid  dividends  on the Common Stock and
does not intend to pay cash  dividends  on the Common  Stock in the  foreseeable
future.  The Company intends to retain future  earnings,  if any, to finance the
development  and  expansion of its  business.  In  addition,  the payment of any
dividends  on the Common Stock is  effectively  prohibited  by the  restrictions
contained  in the  Company's  indentures  and in the Second Amended and Restated
Articles of Incorporation of Holdings,  which prohibits Holdings from making any
material  payment to the  Company.  Certain  of the  Company's  debt  facilities
contain  covenants  which also may  restrict the  Company's  ability to pay cash
dividends.

     In September and October 1997,  the Company's new wholly owned  subsidiary,
ICG Funding,  LLC, a Delaware  limited  liability  company,  completed a private
placement  of  $132.25  million  of 6  3/4%  Preferred  Securities.  The 6  3/4%
Preferred  Securities  are  mandatorily  redeemable  November  15,  2009  at the
liquidation  preference  of  $50.00  per  security,   plus  accrued  and  unpaid
dividends.  Dividends on the 6 3/4%  Preferred  Securities are cumulative at the
rate of 6 3/4% per annum and are payable in cash through  November 15, 2000 and,
thereafter,  in cash or shares of Common Stock at the option of ICG Funding. The
6 3/4% Preferred Securities are exchangeable,  at the option of the holder, into
Common Stock at an exchange  price of $24.025 per share,  subject to adjustment.
ICG Funding may, at its option,  redeem the 6 3/4%  Preferred  Securities at any
time on or after  November 18, 2000.  Prior to that time, ICG Funding may redeem
the 6 3/4%  Preferred  Securities  if the current  market  value of Common Stock
equals or exceeds the exchange  price,  for at least 20 days of any  consecutive
30-day trading period, by 170% prior to November 16, 1998; by 160% from November
16, 1998 through  November 15, 1999;  and by 150% from November 16, 1999 through
November 15, 2000. The 6 3/4% Preferred Securities and the Common Stock issuable
upon exchange of such securities have been registered  under the Securities Act.
The  6  3/4%  Preferred   Securities  are  guaranteed  by  ICG  on  a  full  and
unconditional basis.

     In October 1997,  the Company sold 687,221 shares of Common Stock (the "CBG
Shares") to certain  shareholders  of CBG in connection  with the acquisition of
CBG for a purchase price of  approximately  $16.0  million.  The sale of the CBG
Shares was exempt from  registration  under Rule 4 (2) under the  Securities Act
because  the offers and sales were made to a limited  number of  investors  in a
private transaction.  Resale of the CBG Shares was subsequently  registered on a
Form S-3  registration  statement  which was  declared  effective on October 31,
1997.

ITEM 6.  SELECTED FINANCIAL DATA

     The selected  financial  data for each fiscal year in the four-year  period
ended  September  30, 1996,  the three  months  ended  December 31, 1996 and the
fiscal  year  ended  December  31,  1997  has  been  derived  from  the  audited
Consolidated  Financial  Statements of the Company.  The  information  set forth
below should be read in conjunction with the Consolidated  Financial  Statements
of the Company and the notes thereto  included  elsewhere in this Annual Report.
The Company's  development  and expansion  activities,  including  acquisitions,
during the periods shown below materially  affect the comparability of this data
from one  period to  another.  See  "Management's  Discussion  and  Analysis  of
Financial Condition and Results of Operations."

(1)  During  fiscal  1996,  the  Company  changed its method of  accounting  for
     long-term  telecom services  contracts to recognize revenue as services are
     provided.  Other than the cumulative  effect of adopting this new method of
     accounting,  the  effect  of this  change  in  accounting  for the  periods
     presented was not significant. See "Management's Discussion and Analysis of
     Financial Condition and Results of Operations Accounting Change."

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
        CONDITION AND RESULTS OF OPERATIONS

     The following discussion includes certain forward-looking  statements which
are affected by important factors  including,  but not limited to, dependence on
increased traffic on the Company's facilities,  the successful implementation of
the Company's strategy of offering an integrated  telecommunications  package of
local, long distance,  data and value-added  services,  continued development of
the Company's network  infrastructure  and actions of competitors and regulatory
authorities  that  could  cause  actual  results to differ  materially  from the
forward-looking  statements.  The results for the 12 months  ended  December 31,
1996 and the three  months  ended  December  31, 1995 have been derived from the
Company's  Consolidated  Financial  Statements included elsewhere herein and the
Company's unaudited  Consolidated Financial Statements included in the Company's
Forms  10-Q filed  with the SEC.  The  Company  changed  its fiscal  year end to
December 31 from September 30, effective January 1, 1997. All dollar amounts are
in U.S. dollars.

Company Overview

     The  Company is one of the  nation's  leading  competitive  ICPs,  based on
estimates of the industry's 1997 revenue. ICPs seek to provide an alternative to
ILECs, long distance carriers,  ISPs and other communications  service providers
for a full range of  communications  services  in the  increasingly  deregulated
telecommunications  industry.  Through its CLEC operations, the Company operates
networks in four regional clusters covering major metropolitan statistical areas
in California,  Colorado,  Ohio and the  Southeast.  The Company also provides a
wide range of network systems integration  services,  maritime and international
satellite transmission services and subsequent to January 21, 1998, a variety of
Internet connectivity and other value-added Internet services.  Network Services
consist of information  technology  services and selected  networking  products,
focusing on network design,  installation,  maintenance  and support.  Satellite
Services  consist of satellite  voice and data  services to major cruise  lines,
commercial  shipping vessels,  yachts, the U.S. Navy and offshore oil platforms.
The Company  intends to dispose of its Satellite  Services  operations to better
focus its efforts on its core Telecom Services unit, although it has not entered
into a formal arrangement for such disposition.  As a leading participant in the
rapidly growing competitive local  telecommunications  industry, the Company has
experienced significant growth, with total revenue increasing from approximately
$111.6 million for fiscal 1995 to approximately  $273.4 million for fiscal 1997.
The  Company's  rapid  growth  is  the  result  of  the  initial   installation,
acquisition  and  subsequent  expansion  of its  fiber  optic  networks  and the
expansion of its communication service offerings.

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

     The Telecommunications Act and pro-competitive state regulatory initiatives
have substantially changed the telecommunications  regulatory environment in the
United States. Due to these regulatory changes,  the Company is now permitted to
offer all interstate and intrastate  telephone services,  including  competitive
local dial tone.  The Company is marketing  and selling local dial tone services
in major metropolitan areas in the following  regions:  California,  which began
service in late January  1997,  followed by Ohio in February  1997,  Colorado in
March 1997 and the Southeast in May 1997.  During fiscal 1997,  the Company sold
178,470 local access lines,  of which 141,035 were in service as of December 31,
1997. In addition,  the Company's  operating  networks have grown from 627 fiber
route  miles at the end of fiscal 1995 to 3,043 fiber route miles as of December
31, 1997. The Company has 19 operating high capacity  digital voice switches and
15 data  communications  switches,  and plans to install additional  switches as
demand warrants. As a complement to its local exchange services, the Company has
begun marketing bundled service offerings which include long distance,  enhanced
telecommunications  services  and  data  services  and  plans to  intensify  the
offerings of such services in the near term.

     The  Company  will  continue to expand its  network  through  construction,
leased  facilities,  strategic  alliances  and  mergers  and  acquisitions.  For
example,  in January  1998,  the Company  completed  its merger with  NETCOM,  a
provider  of  Internet  connectivity  and Web site  hosting  services  and other
value-added services,  located in San Jose, California. For calendar years 1995,
1996 and 1997,  NETCOM  reported  revenue of $52.4  million,  $120.5 million and
$160.7  million,  respectively,  and EBITDA  losses of $(6.3)  million,  $(20.3)
million  and $(1.7)  million,  respectively.  The Company  will  account for the
business  combination  under the pooling of interests  method of accounting  and
accordingly,  the Company's financial statements will be restated to reflect the
operations  of NETCOM and the  Company on a  combined  basis for all  historical
periods.  Also, in two transactions  occurring  October 1997 and March 1998, the
Company purchased 100% of the capital stock of CBG, an Ohio based local exchange
and centrex reseller which had, at December 31, 1997,  48,256 local access lines
in service,  principally  pursuant to various resale and other  agreements  with
Ameritech,  the ILEC in the markets it serves.  Further,  for the calendar years
1995,  1996 and 1997,  CBG's  revenue was  approximately  $15.4  million,  $21.4
million and $33.8 million,  respectively,  and EBITDA losses were  approximately
$(1.3) million, $(1.0) million and $(3.2) million,  respectively. The operations
of CBG have been included in the Company's  operations for the period subsequent
to October 17, 1997,  the  acquisition  closing date.  In May 1997,  the Company
entered into an agreement  with a subsidiary of Southern  permitting the Company
to construct a 100-mile fiber optic network in the Atlanta metropolitan area. In
addition,  the Company  expanded its geographic  focus to include Texas (and may
also expand to Arkansas,  Louisiana and Oklahoma) through its strategic alliance
with CSW that will  develop and market  telecommunications  services,  including
local service,  in these markets.  In June 1997, the Company entered into an IRU
agreement  with Qwest for  approximately  1,800 miles of fiber optic network and
additional broadband capacity in California,  Colorado,  Ohio and the Southeast.
This new capacity will be used for the transmission of local,  long distance and
communications services in and between the Company's markets.

     Telecom  Services  revenue has increased from $32.3 million for fiscal 1995
to $177.7 million for fiscal 1997. The Company has experienced  declining prices
and increasing  price  competition for access services which, to date, have been
more than offset by increasing network usage. The Company expects to continue to
experience declining prices and increasing price competition for the foreseeable
future.

     In conjunction with the increase in its service offerings,  the Company 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.  This has and will continue to have an adverse effect on
operating   margins  until  such  time  as  sufficient   volumes  of  customers'
telecommunications  traffic are attained.  As the Company's customer base grows,
the Company  anticipates  that  operating  margins will  improve as  incremental
revenue   will   exceed   incremental   operating   expenses.    The   preceding
forward-looking statement is dependent upon the successful implementation of the
Company local dial tone,  data and long distance  services  strategy,  continued
development of the Company's  network  infrastructure,  increased traffic on the
Company's  facilities,  any or all of which may not occur,  and upon  actions of
competitors and regulatory authorities.

     Currently  the  Company has  experienced  and may  continue  to  experience
negative  operating  margins  from its  wholesale  switched  services  while its
networks are in the  development and  construction  phases and while the Company
relies  on ILEC  networks  to  carry a  significant  portion  of its  customers'
switched  traffic.  The Company expects overall  operating margins from switched
services  to improve as local dial tone,  local  toll,  long  distance  and data
communications  services become a relatively  larger portion of its business mix
and the Company de-emphasizes its wholesale switched services. In addition,  the
Company believes that the unbundling of ILEC services and the  implementation of
local telephone number portability, which are mandated by the Telecommunications
Act,  will  reduce  the  Company's  costs of  providing  switched  services  and
facilitate the marketing of local and other  services.  The Company has recently
raised prices on its  wholesale  switched  services  product in order to improve
margins  and free up  switch  port  capacity  for its  higher  margin  dial tone
product.

     The Company  believes that the  provisions of the  Telecommunications  Act,
including the opening of the local  telephone  services  market to  competition,
will  facilitate  the  Company's  plan to  provide a full  array of local,  long
distance  and data  communications  services.  In order to fully  implement  its
strategy,  the Company must make  significant  capital  expenditures  to provide
additional switching capacity, network infrastructure and electronic components.
The Company must also make significant  investments and expenditures to develop,
train and manage its marketing and sales personnel.

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

(1)  During  fiscal  1996,  the  Company  changed its method of  accounting  for
     long-term  telecom services  contracts to recognize revenue as services are
     provided.  See "-Accounting  Changes." Other than the cumulative  effect of
     adopting  this new  method of  accounting,  the  effect  of this  change in
     accounting for the periods presented was not significant.

Fiscal 1997 Compared to 12 Months Ended December 31, 1996

     Revenue. Revenue for fiscal 1997 increased $82.7 million or 43% from the 12
months ended December 31, 1996. Telecom Services revenue increased 63% to $177.7
million due to an increase in network usage for both switched and special access
services, offset in part by a decline in average unit pricing. Switched services
revenue  increased from $48.1 million (44% of Telecom Services  revenue) for the
12 months  ended  December 31, 1996 to $93.9  million  (53% of Telecom  Services
revenue) for fiscal 1997.  Switched access  (terminating  long distance) revenue
represented  approximately  77%  of  the  Company's  switched  services  revenue
component for fiscal 1997, compared to 100% for the 12 months ended December 31,
1996.  Special  access  revenue  increased  from $39.4  million  (36% of Telecom
Services  revenue)  for the 12 months ended  December 31, 1996 to $55.4  million
(31% of Telecom  Services  revenue)  for fiscal 1997.  Also  included in Telecom
Services revenue for fiscal 1997 is $28.3 million  generated by Zycom,  compared
to $21.5  million for the same  12-month  period in 1996.  The increase in Zycom
revenue  for  fiscal  1997 as  compared  to the same  period in 1996  relates to
changes  in the  classification  of certain  operating  costs as a result of the
Company entering into long-term contracts with its major customers.  These costs
were netted against revenue through April 1996 due to the uncertainty of renewal
of short-term customer contracts.  At December 31, 1997, the Company had 141,035
access lines in service  compared to zero at December 31, 1996.  Special  access
network usage reflected in voice grade equivalents  ("VGEs")  increased 49% from
748,528 VGEs at December 31, 1996,  to 1,111,697  VGEs at December 31, 1997.  At
December 31,  1997,  the Company had 2,321  buildings  connected to its networks
compared to 2,069  buildings  connected  at  December  31,  1996.  Additionally,
switched  minutes of use increased 43% from  approximately  2.0 billion  minutes
during the 12 months  ended  December  31,  1996 to  approximately  2.9  billion
minutes during fiscal 1997. Revenue from long distance and data services did not
generate a material  portion of total  revenue  during  either  period.  Network
Services  revenue  increased 9% to $65.7  million for fiscal 1997 as compared to
$60.4 million for the 12 months ended December 31, 1996. The increase in Network
Services  revenue is due to a single  equipment sale during fiscal 1997 for $3.2
million  as well as general  increases  in volume.  Satellite  Services  revenue
increased  $8.7 million,  or 41%, to $30.0 million for fiscal 1997,  compared to
the 12 months ended  December 31, 1996.  This  increase is primarily  due to the
operations of MCN,  which  comprised  $6.3 million of total  Satellite  Services
revenue for fiscal 1997 compared to $1.8 million during the same 12-month period
in 1996.  The remaining  increase can be attributed to the general growth of MTN
and its increased sales of C-Band equipment to offshore oil and gas customers.

     Operating  costs.  Total  operating  costs for fiscal 1997 increased  $88.3
million,  or 56%, from the 12 months ended December 31, 1996.  Telecom  Services
operating  costs  increased  from  $101.3  million,  or 93% of Telecom  Services
revenue,  for the 12 months ended December 31, 1996 to $175.8 million, or 99% of
Telecom Services  revenue,  for fiscal 1997.  Telecom  Services  operating costs
consist  of  payments  to ILECs for the use of  network  facilities  to  support
special and switched access services, network operating costs, right of way fees
and other  costs.  The  increase  in  operating  costs in  absolute  dollars  is
attributable  to the  increase in switched  access  services and the addition of
engineering  and  operations  personnel  dedicated to the  development  of local
exchange  services.  The  increase in operating  costs as a percentage  of total
revenue is due primarily to the increase in switched  access  services  revenue,
and the investment in the  development of local  exchange  services  without the
benefit of  substantial  corresponding  revenue in the same period.  The Company
expects  that the Telecom  Services  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 ILEC  facilities  and obtains the right to use unbundled
ILEC  facilities  on  satisfactory  terms,  any or all of which  may not  occur.
Network Services operating costs increased 16% to $53.9 million and increased as
a  percentage  of  Network  Services  revenue  from 77% for the 12 months  ended
December 31, 1996 to 82% for fiscal 1997. The increase is due to a substantially
lower margin earned on equipment  sales (which  constituted a larger  portion of
1997  revenue)  relative to other  services and certain  indirect  project costs
included in operating  costs  during  fiscal 1997 which were treated as selling,
general and  administrative  expenses  during the comparable  12-month period in
1996.  Network  Services  operating  costs  include the cost of equipment  sold,
direct  hourly  labor and  other  indirect  project  costs.  Satellite  Services
operating  costs  increased to $16.7 million for fiscal 1997, from $10.2 million
for the 12 months ended December 31, 1996. Satellite Services operating costs as
a percentage of Satellite  Services  revenue also  increased from 48% for the 12
months ended  December 31, 1996 to 56% for fiscal 1997.  This increase is due to
an increase in MCN's sales as well the increased volume of equipment sales, both
of which provide lower margins than other maritime services.  Satellite Services
operating  costs consist  primarily of  transponder  lease costs and the cost of
equipment sold.

     Selling,  general  and  administrative   expenses.   Selling,  general  and
administrative  ("SG&A")  expenses for fiscal 1997 increased  $68.4 million,  or
83%,  compared to the 12 months  ended  December  31,  1996.  This  increase was
principally  due to the  continued  rapid  expansion  of the  Company's  Telecom
Services networks and related significant  additions to the Company's management
information systems,  customer service,  marketing and sales staffs dedicated to
the  expansion of the  Company's  networks and  implementation  of the Company's
expanded services strategy, primarily the development of local and long distance
telephone  and data  communications  services.  SG&A expenses as a percentage of
total revenue  increased  from 43% for the 12 months ended  December 31, 1996 to
55% for fiscal 1997.  There is typically a period of higher  administrative  and
marketing  expense  prior to the  generation of  appreciable  revenue from newly
developed  networks or services.  The Company  expects SG&A expenses for Telecom
Services to increase slightly over the near term as a result of hiring new staff
to facilitate the marketing and development of local dial tone, local toll, long
distance and data transmission services.

     Depreciation and  amortization.  Depreciation  and  amortization  increased
$21.8 million, or 62%, for fiscal 1997, compared to the 12 months ended December
31, 1996, due to increased  investment in depreciable  assets resulting from the
continued expansion of the Company's networks and services.  The Company reports
high levels of depreciation  expense  relative to revenue during the early years
of operation of a new network  because the full cost of a network is depreciated
using the straight-line  method despite the low rate of capacity  utilization in
the early stages of network operation.

     Net loss  (gain) on  disposal  of  long-lived  assets.  Net loss  (gain) on
disposal of long-lived  assets decreased from a net loss of $3.3 million for the
12 months ended December 31, 1996 to a net gain of $0.7 million for fiscal 1997.
Net loss on disposal of long-lived  assets for the 12 months ended  December 31,
1996 includes the loss  recorded on the sale of four of the Company's  teleports
used in its Satellite Services  operations ($1.1 million),  the loss recorded on
the  disposal of other  operating  assets  ($2.7  million) and a write-off of an
investment ($0.3 million), offset by a gain on the sale on sale of the Company's
50% interest in the Phoenix  network joint venture  ($0.8  million).  For fiscal
1997,  net loss on disposal of  long-lived  assets  primarily  relates to losses
recorded on the disposal of the Company's investment in its Melbourne network.

     Provision for impairment of long-lived assets.  For fiscal 1997,  provision
for  impairment of long-lived  assets  includes the  write-down of the Company's
investment in StarCom International Optics Corporation, Inc. ($5.2 million), MCN
($2.9  million),  Zycom ($2.7  million) and Nova-Net ($0.9 million) as well as a
write-down of other operating assets ($0.3 million). Provision for impairment of
long-lived  assets for the 12 months ended December 31, 1996 includes  valuation
allowances for the amounts  receivable for advances made to the Phoenix  network
joint  venture  included  in  long-term  note  receivable  ($5.8  million),  the
investments in the Melbourne  network ($2.7 million) and the Satellite  Services
Mexico  subsidiary  ($0.1 million) and the note receivable  from NovoComm,  Inc.
($1.3 million). Provision for impairment of long-lived assets was recorded based
on management's  estimate of the net realizable value of the Company's assets at
December 31, 1996 and 1997.

     Interest  expense.  Interest  expense  increased $22.6 million,  from $95.0
million for the 12 months ended  December 31, 1996, to $117.5 million for fiscal
1997,  which  includes  $105.5 million of non-cash  interest.  This increase was
primarily  attributable to an increase in long-term debt,  primarily the 11 5/8%
Notes  issued  in March  1997.  In  addition,  the  Company's  interest  expense
increased,  and will continue to increase,  because the principal  amount of its
indebtedness  increases until the Company's  senior  indebtedness  begins to pay
interest in cash.

     Interest income. Interest income increased $0.4 million, from $21.5 million
for the 12 months ended  December 31, 1996 to $21.9 million for fiscal 1997. The
increase is attributable to the increase in cash and invested cash balances from
the proceeds from the issuances of the 11 5/8% Notes and 14% Preferred  Stock in
March 1997 and the 6 3/4% Preferred Securities in September and October 1997.

     Other,  net. Other,  net decreased from $3.9 million net expense for the 12
months  ended  December  31, 1996 to $0.7  million net expense for fiscal  1997.
Other  expense  recorded  for the 12 months  ended  December  31, 1996  consists
primarily  of the  write-off of deferred  financing  costs  associated  with the
conversion  or repayment of debt and  litigation  settlement  costs.  For fiscal
1997, other, net consists primarily of litigation  settlement costs and the loss
on disposal of non operating assets.

     Minority  interest  in share of  losses,  net of  accretion  and  preferred
dividends on preferred securities of subsidiaries. Minority interest in share of
losses,  net of accretion  and  preferred  dividends on preferred  securities of
subsidiaries increased $10.7 million, from $27.1 million for the 12 months ended
December  31,  1996 to $37.8  million  for  fiscal  1997.  The  increase  is due
primarily to the  issuances of the 14%  Preferred  Stock in March 1997 and the 6
3/4%  Preferred  Securities  in  September  and October  1997.  Offsetting  this
increase is $12.3 million  recorded during the 12 months ended December 31, 1996
for the  excess of the  redemption  price  over the  carrying  amount of the 12%
redeemable  preferred  stock of  Holdings  ("12%  Redeemable  Preferred  Stock")
redeemed in April 1996.  Minority interest in share of losses,  net of accretion
and preferred dividends on preferred securities of subsidiaries  recorded during
fiscal 1997  consists of the  accretion  of issue costs ($0.9  million)  and the
accrual of the preferred security dividends ($38.9 million)  associated with the
6  3/4%  Preferred  Securities,   the  14%  Preferred  Stock  and  the  14  1/4%
Exchangeable Preferred Stock Mandatorily Redeemable 2007 (the "14 1/4% Preferred
Stock"), offset by minority interest in losses of subsidiaries of $2.0 million.

     Share of losses of joint venture and investment. Effective October 1, 1996,
the Company sold its 50% interest in the Phoenix  network  joint  venture.  As a
result,  no share of losses in joint venture was recorded during fiscal 1997, as
compared to the $1.6 million loss recorded during the comparable 12-month period
in 1996.

     Net loss. Net loss increased  $128.4 million,  or 64%, due to the increases
in operating  costs,  SG&A  expense,  depreciation  and  amortization,  interest
expense and minority interest in share of losses, net of accretion and preferred
dividends on preferred securities of subsidiaries noted above.

Three Months Ended December 31, 1996 Compared to Three Months Ended 
December 31, 1995

     Revenue.  Revenue for the three  months ended  December 31, 1996  increased
$21.6  million,  or 61%,  from the three  months ended  December  31, 1995.  The
increase in total revenue reflects continued growth in Telecom Services, Network
Services  and  Satellite  Services,  offset  slightly  by the  loss  in  revenue
resulting  from the sale of four of the  Company's  teleports  during the second
quarter of fiscal 1996. Telecom Services revenue increased 157% to $34.8 million
due to an  increase  in  network  usage for both  switched  and  special  access
services, offset in part by a decline in average unit pricing. Switched services
revenue  increased from $5.1 million (38% of Telecom  Services  revenue) for the
three months ended December 31, 1995, to $16.4 million (47% of Telecom  Services
revenue) for the three months ended December 31, 1996.  Switched  access revenue
represented  substantially  all  of  the  Company's  switched  services  revenue
component for the three months ended  December 31, 1996.  Special access revenue
increased  from $7.5  million  (56% of Telecom  Services  revenue) for the three
months  ended  December  31,  1995 to $10.9  million  (31% of  Telecom  Services
revenue) for the three months ended December 31, 1996. Also, included in Telecom
Services  revenue for the three months  ended  December 31, 1996 is $7.5 million
generated by Zycom, compared to $0.9 million for the three months ended December
31, 1995.  Approximately  $6.5 million of the increase in Zycom  revenue for the
three  months  ended  December  31,  1996 as compared to the same period in 1995
relates to changes in the  classification of certain operating costs as a result
of the Company  entering  into  long-term  contracts  with its major  customers.
Network  usage as reflected in VGEs  increased 53% from 488,403 VGEs on December
31, 1995 to 748,528 at December 31, 1996. On December 31, 1996,  the Company had
2,069 buildings  connected to its networks compared to 1,539 buildings connected
on December 31, 1995.  Consistent with  expectations,  Network  Services revenue
growth was  moderate,  increasing  from $15.7  million to $16.0  million for the
three months ended December 31, 1995 and 1996,  respectively,  while the Company
repositioned its systems and operations to improve operating results.  Satellite
Services  revenue  remained  relatively  stable between the three-month  periods
ended  December  31,  1995 and 1996 as a result  of the  offsetting  effects  of
increased  maritime minutes of use from cruise ships and no revenue in the three
months ended  December 31, 1996 from the four teleports sold in March 1996. On a
pro forma basis to reflect the sale of the  teleports,  the Company's  Satellite
Services  revenue for the three months ended December 31, 1995 and 1996 was $3.7
million and $6.2 million, respectively.

                                       40


     Operating costs.  Total operating costs for the three months ended December
31, 1996 increased $22.8 million,  or 84%, from the same period in 1995. Telecom
Services  operating  costs  increased  from $11.9  million,  or 88%,  of Telecom
Services revenue for the three months ended December 31, 1995, to $34.5 million,
or 99%, of Telecom  Services  revenue for the three  months  ended  December 31,
1996. The increase in operating costs in absolute dollars is attributable to the
increase  in switched  access  services  and the  addition  of  engineering  and
operations  personnel  dedicated to the development of local exchange  services.
The increase in operating  costs as a percentage  of revenue is due primarily to
the increase in switched access services  revenue.  Network  Services  operating
costs increased 2% to $12.3 million for the three months ended December 31, 1996
and  increased as a percentage of Network  Services  revenue from 76% to 77% for
the  three  month  periods  ended  December  31,  1995 and  1996,  respectively.
Satellite  Services  operating  costs decreased 2% to $3.2 million for the three
months  ended  December  31,  1996.  Satellite  Services  operating  costs  as a
percentage of revenue  declined to 51% of Satellite  Services revenue during the
three  months ended  December  31, 1996,  from 52% during the three months ended
December 31, 1995.  The  decrease in  percentage  of revenue as well as absolute
dollars is  attributable  to the decline in revenue  resulting  from the sale of
four of the Company's  teleports in March 1996,  offset by an increase in higher
margin  maritime  services  revenue at MTN.  Revenue  from  teleport  operations
historically have yielded lower gross margins than maritime services revenue.

     Selling,  general and administrative  expense.  SG&A expenses for the three
months ended December 31, 1996 increased $5.6 million,  or 30%,  compared to the
three months ended December 31, 1995.  This increase was  principally due to the
continued rapid expansion of the Company's Telecom Services networks and related
significant additions to the Company's management information systems,  customer
service,  marketing and sales staffs dedicated to the expansion of the Company's
networks  and  implementation  of  the  Company's  expanded  services  strategy,
primarily the development of the Company's CLEC  operations.  SG&A expenses as a
percentage  of total  revenue was 43% for the three  months  ended  December 31,
1996,  compared to 53% for the same period in 1995.  SG&A  expenses  for Network
Services  decreased  both in  absolute  dollars and as a  percentage  of Network
Services  revenue due to approximately  $0.7 million in  non-recurring  charges,
primarily  legal  accruals,  recorded during the three months ended December 31,
1995.  Satellite  Services SG&A expenses  decreased in absolute dollars and as a
percentage  of Satellite  Services  revenue due to cost  control  efforts by the
Company's  management.  Other corporate expenses increased from $4.0 million, or
11% of total  revenue,  for the three  months  ended  December  31, 1995 to $5.7
million, or 10% of total revenue,  for the three months ended December 31, 1996.
This  increase  is  primarily   attributable   to  the  addition  of  employees,
principally  human  resources  and  regulatory  personnel,  for the  purpose  of
managing  the  Company's  growth and its  expansion  into new markets as allowed
under the Telecommunications Act.

                                       41


     Depreciation  and  amortization  expense.   Depreciation  and  amortization
expense increased $4.9 million, or 100%, for the three months ended December 31,
1996,  as  compared  to the same period in 1995.  Depreciation  of fixed  assets
increased  by  approximately  $2.3  million  as a result  of the  shortening  of
estimated  depreciable  lives during fiscal 1996,  as discussed in  "-Accounting
Changes,"  and an  increase in  depreciable  fixed  assets due to the  continued
expansion of the Company's  networks.  The increase in depreciation  expense was
offset  slightly  due to the sale of four of the  Company's  teleports  in March
1996.

     Net loss  (gain) on  disposal  of  long-lived  assets.  Net loss  (gain) on
disposal of long-lived  assets decreased from a net loss of $1.0 million for the
three months ended December 31, 1995 to a net gain of $0.8 million for the three
months ended  December 31, 1996.  Net loss on disposal of long-lived  assets for
the three months  ended  December  31, 1995  includes  the  write-off of certain
operating  assets.  For the three  months ended  December 31, 1996,  net gain on
disposal of long-lived  assets consists of the gain on sale of the Company's 50%
interest in the Phoenix network joint venture.

     Interest expense.  Interest expense  increased by $9.3 million,  from $15.2
million for the three  months ended  December 31, 1995 to $24.5  million for the
three months ended  December 31, 1996,  which included $22.7 million of non-cash
interest.  This  increase was  attributable  to an increase in  long-term  debt,
primarily  the 12 1/2% Senior  Discount  Notes (the "12 1/2%  Notes")  issued in
April 1996 and an increase in capitalized  lease  obligations to finance Telecom
Services equipment used in the expansion of the Company's networks.

     Interest  income.  Interest  income  increased  $2.2 million from the three
months  ended  December  31,  1995 to $6.0  million for the three  months  ended
December 31, 1996. The increase is  attributable  to the interest  earned on the
proceeds from the issuance of the 12 1/2% Notes and the 14 1/4% Preferred  Stock
in April 1996.

     Share of losses of joint venture and investment. As a result of the sale of
the Company's 50% interest in the Phoenix  network  joint  venture,  no share of
losses in joint venture was recorded  during the three months ended December 31,
1996, as compared to the $0.2 million recorded during the same period in 1995.

     Other,  net.  Other,  net for the three months ended  December 31, 1996 was
$0.1  million net  expense as compared to a minor net gain for the three  months
ended December 31, 1995.  Other expense  recorded during the three-month  period
ended December 31, 1996 consists of miscellaneous other expenses.

                                       42


     Minority  interest  in share of  losses,  net of  accretion  and  preferred
dividends on preferred securities of subsidiaries. Minority interest in share of
losses,  net of accretion  and  preferred  dividends on preferred  securities of
subsidiaries  increased  $1.8  million,  from $3.2  million for the three months
ended  December 31, 1995 to $5.0 million for the three months ended December 31,
1996.  The increase is due  primarily  to the issuance of the 14 1/4%  Preferred
Stock in April 1996.  Minority interest in share of losses, net of accretion and
preferred dividends on preferred securities of subsidiaries  recorded during the
current  three-month period ended December 31, 1996 consists of the accretion of
issue costs ($0.1 million) and the accrual of the preferred stock dividend ($5.7
million)  associated  with  the 14 1/4%  Preferred  Stock,  offset  by  minority
interest in losses of subsidiaries of $0.8 million.

     Cumulative  effect of change  in  accounting  for  revenue  from  long-term
telecom services  contracts.  The cumulative  effect of change in accounting for
revenue from long-term  telecom  services  contracts  recorded  during the three
months ended  December 31, 1995 is due to the change in accounting  principle as
described  in  "-Accounting  Changes." As the change in  accounting  was applied
retroactively as of October 1, 1995, no similar amounts were recorded during the
three months ended December 31, 1996.

     Net loss. Net loss increased $15.2 million,  or 44%, due to the increase in
operating  costs,  SG&A expenses,  depreciation  and  amortization  and interest
expense noted above.

Fiscal 1996 Compared to Fiscal 1995

     The following  information  reflects the results of  operations  for fiscal
1996 compared to the pro forma results of operations  for fiscal 1995,  assuming
the change in accounting for long-term telecom services  contracts  described in
"-Accounting Change" had been applied retroactively.

     Revenue.  Revenue for fiscal 1996  increased  $58.2  million,  or 52%, from
fiscal 1995. The increase in total revenue reflects  continued growth in Telecom
Services,  Network Services and Satellite Services,  offset slightly by the loss
in revenue resulting from the sale of four of the Company's  teleports.  Telecom
Services  revenue  increased 177% to $87.7 million due to an increase in network
usage for both switched and special access services, offset in part by a decline
in average unit prices. Switched services revenue, consisting solely of switched
access services,  increased from $5.8 million (18% of Telecom Services  revenue)
for fiscal 1995, to $36.7 million (42% of Telecom  Services  revenue) for fiscal
1996.  Special  access  revenue  increased  from $25.1  million  (78% of Telecom
Services  revenue)  for fiscal 1995 to $36.1  million  (41% of Telecom  Services
revenue) for fiscal 1996. Also included in Telecom  Services  revenue for fiscal
1996 is $14.9  million  generated  by Zycom,  compared to $1.4 million in fiscal
1995.  Approximately  $10.6 million of the increase in Zycom revenue  relates to
changes  in the  classification  of certain  operating  costs as a result of the
Company  entering into  long-term  contracts with its major  customers.  Network
usage as reflected  in VGEs  increased  47% from  430,535 VGEs on September  30,
1995, to 630,697 VGEs on September 30, 1996. On September 30, 1996,  the Company
had 2,067  buildings  connected  to its  networks  compared  to 1,375  buildings
connected on September 30, 1995. Consistent with expectations,  Network Services
revenue  growth was moderate,  increasing  from $58.8 million to $60.1  million,
while the Company  repositioned its systems and operations to improve  operating
results.  Satellite  Services  revenue  increased 4% to $21.3 million for fiscal
1996 primarily due to increased maritime minutes of use from cruise ships offset
in  part by the  decrease  resulting  from  the  sale  of four of the  Company's
teleports.  Satellite  Services revenue for fiscal 1995 and 1996, on a pro forma
basis to reflect the sale of  teleports,  was $11.4  million and $18.9  million,
respectively.  Satellite  Services revenue decreased $0.4 million from the third
quarter of fiscal 1996 to the fourth  quarter of fiscal  1996.  The  decrease in
revenue was primarily due to three Navy vessels being in "dry dock."

                                       43


     Operating  costs.  Total  operating  costs for fiscal 1996 increased  $56.4
million,  or 72%, from fiscal 1995.  Telecom Services  operating costs increased
from $21.8 million, or 69% of Telecom Services revenue for fiscal 1995, to $78.7
million,  or 90% of Telecom  Services  revenue for fiscal 1996.  The increase in
operating costs in absolute  dollars is attributable to the increase in switched
access services and the expansion in off-net  special access service  offerings.
The  increase  in  operating  costs  as a  percentage  of total  revenue  is due
primarily to the increase in switched access services revenue.  Network Services
operating  costs  increased 1% to $46.3 million and decreased as a percentage of
Network  Services  revenue  from 78% for  fiscal  1995 to 77% for  fiscal  1996.
Satellite  Services  operating costs decreased to $10.3 million for fiscal 1996,
from $11.1  million for fiscal 1995.  Satellite  Services  operating  costs as a
percentage of revenue also declined to 48% for fiscal 1996,  compared to 54% for
fiscal  1995.  The  decrease  both in absolute  dollars and as a  percentage  of
revenue is  attributable  to the decline in revenue  resulting  from the sale of
four of the  Company's  teleports,  partially  offset by an  increase  in higher
margin maritime services revenue at MTN.

     Selling,  general and administrative expense. SG&A expenses for fiscal 1996
increased  $13.8  million,  or 22%,  compared to fiscal 1995.  This increase was
principally  due to the  continued  rapid  expansion  of the  Company's  Telecom
Services networks and related significant  additions to the Company's management
information systems, marketing and sales staff dedicated to the expansion of the
Company's  networks  and  implementation  of  the  Company's  switched  services
strategy and  development  of the Company's  CLEC  operations.  A portion of the
increase  was  also  attributable  to  approximately   $1.8  million  of  legal,
accounting,  and SEC filing  fees  incurred in the  incorporation  of a new U.S.
publicly traded holding company,  ICG  Communications,  Inc., and  approximately
$1.3  million  of  consulting  fees  related  to  various  process   improvement
initiatives.  SG&A  expenses as a percentage of total revenue was 45% for fiscal
1996,  compared to 57% for fiscal  1995.  SG&A  expenses  for  Network  Services
increased  due to increased  engineering,  marketing  and sales staff to support
growth  in  network  system  installations.  Satellite  Services  SG&A  expenses
increased primarily due to the growth of MTN and MCN.

     Depreciation and  amortization.  Depreciation  and  amortization  increased
$13.7 million, or 83%, for fiscal 1996 compared to fiscal 1995.  Depreciation of
fixed  assets  increased  by  approximately  $7.0  million  as a  result  of the
shortening of estimated  depreciable  lives discussed in "-Accounting  Changes,"
and an increase in  depreciable  fixed assets due to the continued  expansion of
the Company's networks. The increase in depreciation expense was offset slightly
due to the sale of four of the Company's teleports.

     Net loss  (gain) on  disposal  of  long-lived  assets.  Net loss  (gain) on
disposal of long-lived  assets increased to $5.1 million during fiscal 1996 from
$0.2 million during fiscal 1995.  Net loss on disposal of long-lived  assets for
fiscal 1996  includes  the loss  recorded  on the sale of four of the  Company's
teleports used in its Satellite  Services  operations  ($1.1 million),  the loss
recorded  on the  disposal  of  other  operating  assets  ($3.7  million)  and a
write-off of an investment ($0.3 million).
<PAGE>
                                       44


     Provision for impairment of long-lived assets.  Provision for impairment of
long-lived  assets  increased $3.0 million from fiscal 1995 to $10.0 million for
fiscal  1996.  The  amount  recorded  during  fiscal  1996  includes   valuation
allowances for the amounts  receivable for advances made to the Phoenix  network
joint  venture  included in  long-term  notes  receivable  ($5.8  million),  the
investment in the Melbourne  network ($2.7  million),  the note  receivable from
NovoComm, Inc. ($1.3 million) and the Satellite Services Mexico subsidiary ($0.2
million).  The fiscal 1995 amount includes an allowance for an investment  ($2.0
million) and a write-down in the goodwill  associated  with the  acquisition  of
Nova-Net  ($5.0  million).  Provision for  impairment  of long-lived  assets was
recorded  based on  management's  estimate  of the net  realizable  value of the
Company's assets at September 30, 1995 and 1996.

     Interest expense.  Interest expense increased by $61.3 million,  from $24.4
million for fiscal 1995 to $85.7 million for fiscal 1996,  which  included $66.5
million of non-cash  interest.  This increase was attributable to an increase in
long-term  debt,  primarily the 13 1/2% Senior  Discount Notes due 2005 (the "13
1/2%  Notes")  issued in August 1995 and the 12 1/2% Notes issued in April 1996,
and an increase in  capitalized  lease  obligations  to finance the  purchase of
Telecom  Services and Satellite  Services  equipment.  Also included in interest
expense is a charge of  approximately  $11.5  million for the  payments  made to
holders of the 13 1/2%  Notes with  respect to  consents  to  amendments  to the
indenture  governing the 13 1/2% Notes in order to permit the offering of the 13
1/2% Notes in April 1996.

     Interest income.  Interest income increased $15.1 million from fiscal 1995.
The  increase is  attributable  to the increase in cash from the proceeds of the
issuance  of the 13 1/2% Notes in August  1995 and the 12 1/2% Notes and 14 1/4%
Preferred Stock in April 1996.

     Share of losses of joint  venture  and  investment.  Share of losses in the
Phoenix network joint venture,  in which the Company held a 50% equity interest,
increased  $1.1  million,  or 145%,  from fiscal 1995 to $1.8 million for fiscal
1996  due to  increased  losses  resulting  from  the  continued  expansion  and
implementation of switched access services.

     Other,  net. Other,  net increased from $0.5 million net expense for fiscal
1995 to $3.9  million net expense for fiscal  1996.  Other  expense  recorded in
fiscal 1996 consists  primarily of settlement costs of certain  litigation ($1.2
million)  and the  write-off  of deferred  financing  costs upon  conversion  or
settlement of debt ($2.7 million).

     Minority  interest  in share of  losses,  net of  accretion  and  preferred
dividends on preferred securities of subsidiaries. Minority interest in share of
losses,  net of accretion  and  preferred  dividends on preferred  securities of
subsidiaries  increased  $24.2  million,  from $1.1  million  for fiscal 1995 to
approximately  $25.3  million  for  fiscal  1996.  The  increase  is  due to the
accretion of the unit warrants  issued in  connection  with the 13% Notes ($14.4
million) and issue costs ($1.1 million)  associated with the issuance of the 12%
Redeemable Preferred Stock, of Holdings (the "12% Preferred Stock") accretion of
issue costs associated with the 14 1/4% Preferred Stock ($0.3 million),  accrual
of the preferred  stock  dividend on the 12% Preferred  Stock ($2.1 million) and
the 14 1/4% Preferred Stock ($9.1 million) and the excess  redemption price over
the stated value of the convertible  Series B Preferred Stock of Holdings-Canada
($1.0  million),  partially  offset  by  the  minority  interest  in  losses  of
subsidiaries.

     Income tax  benefit.  Income tax benefit for fiscal 1996 was $5.1  million.
The income tax benefit is due to an  adjustment to the deferred tax liability as
a result of the change in estimated depreciable lives.

     Cumulative  effect of change  in  accounting  for  revenue  from  long-term
telecom  services  contracts.  The  increase in  cumulative  effect of change in
accounting for revenue from long-term  telecom services  contracts is due to the
change in accounting as described in "-Accounting Changes."

     Net loss. Net loss increased $107.5 million,  or 140%, due to the increases
in operating  costs,  SG&A expenses,  depreciation  and  amortization,  interest
expense and minority interest in share of losses, net of accretion and preferred
dividends on preferred securities of subsidiaries noted above.

Quarterly Results

     The following  table  presents  selected  unaudited  operating  results for
three-month  quarterly  periods,  beginning with the three months ended December
31, 1995 and through the three  months  ended  December  31,  1997.  The Company
believes that all necessary adjustments have been included in the amounts stated
below to present fairly the quarterly  results when read in conjunction with the
Company's Consolidated Financial Statements and related notes included elsewhere
in this Annual Report.  Results of operations for any particular quarter are not
necessarily indicative of results of operations for a full year or predictive of
future  periods.   ICG's   development  and  expansion   activities,   including
acquisitions, during the periods shown below materially affect the comparability
of this data from one period to another.

</TABLE>

(1)  During  fiscal  1996,  the  Company  changed its method of  accounting  for
     long-term  telecom services  contracts to recognize revenue as services are
     provided.  See  "-Accounting  Change." Other than the cumulative  effect of
     adopting  this new  method of  accounting,  the  effect  of this  change in
     accounting for the periods presented was not significant.

(2)  EBITDA  consists of revenue less operating  costs and selling,  general and
     administrative  expenses.  EBITDA  is  provided  because  it  is a  measure
     commonly used in the  telecommunications  industry.  EBITDA 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 GAAP for the periods indicated. EBITDA is not a measurement under GAAP
     and is not necessarily  comparable with similarly  titled measures of other
     companies.   Net  cash  flows  from  operating,   investing  and  financing
     activities as determined using GAAP are also presented in Other Data.

(3)  Capital  expenditures  includes  assets  acquired  under capital leases and
     excludes payments for construction of the Company's new headquarters  which
     the  Company  sold in  January  1998  and  leased  back  under a  long-term
     operating lease.

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

(5)  Access  lines in service at December 31, 1997  includes  66,346 lines which
     are  provisioned  through the  Company's  switch and 74,689 lines which are
     provisioned through resale and other agreements with various local exchange
     carriers.  Resale  lines  typically  generate  lower  margins  and are used
     primarily to obtain customers.  Although the Company plans to migrate lines
     from resale to higher margin on-switch lines,  there are no assurances that
     it will be successful in executing this strategy.

(6)  Hybrid buildings  connected  represent buildings connected to the Company's
     network via another carrier's  facilities.  Hybrid buildings  declined from
     September  30, 1996 to December  31, 1996 due to the sale of the  Company's
     50% interest in the Phoenix joint venture.

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

(8)  Fiber  route  miles  refers to the  number of miles of fiber  optic  cable,
     including  leased  fiber.  As of December 31,  1997,  the Company had 3,043
     fiber  route  miles,  of which 171 fiber  route  miles  were  leased  under
     operating  leases.  Fiber route miles under  construction  represents fiber
     under construction which is expected to be operational within six months.

(9)  Fiber strand  miles  refers to the number of fiber route  miles,  including
     leased fiber, along a  telecommunications  path multiplied by the number of
     fiber  strands  along that path.  As of December 31, 1997,  the Company had
     111,435 fiber strand  miles,  of which 3,278 fiber strand miles were leased
     under operating leases.  Fiber strand miles under  construction  represents
     fiber under  construction  which is expected to be  operational  within six
     months.

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

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

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


     The Company's  consolidated  revenue has increased  every quarter since the
first fiscal quarter of 1992,  primarily due to the installation and acquisition
of new  networks,  the  expansion of existing  networks and  increased  services
provided over existing networks. From the third quarter of fiscal 1993 until the
sale of four teleports in the second quarter of fiscal 1996,  Satellite Services
also contributed to the quarterly revenue growth.
<PAGE>
                                       48


     EBITDA,  operating  and net losses  have  generally  increased  immediately
preceding  and during  periods  of  relatively  rapid  network  acquisition  and
expansion  activity.  The increased  quarterly  losses from the first quarter of
fiscal  1995  through the  quarter  ended  December  31,  1997  resulted  from a
combination of increases in negative margin switched access services revenue and
increases in personnel  and other SG&A expenses to support the  acquisition  and
expansion of Telecom  Services  networks,  the  implementation  of the Company's
switched  access services  strategy and development of local exchange  services.
Since the quarter  ended June 30,  1996,  EBITDA  losses have  improved for each
consecutive  quarter.  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  supporting  its Telecom  Services  networks,  any or all of
which may not occur, the Company anticipates that EBITDA losses will continue to
improve in the near term.

     Individual operating units may experience variability in quarter to quarter
revenue due to (i) the type and mix of services available to customers, (ii) the
timing  and size of  contract  orders,  (iii) the  timing of price  changes  and
associated impact on volume, and (iv) customer usage patterns.

 Net Operating Loss Carryforwards

     As of December 31, 1997, the Company had net operating  loss  carryforwards
("NOLs") of  approximately  $353.0  million,  which  expire at various  times in
varying  amounts  through 2012.  However,  due to the provisions of Section 382,
Section 1502 and certain other  provisions of the Internal Revenue Code of 1986,
as  amended  (the  "Code"),  the  utilization  of a portion  of the NOLs will be
limited.  In addition,  the Company is also subject to certain  state income tax
laws which may also limit the utilization of NOLs for state income tax purposes.

     Section 382 of the Code provides annual restrictions on the use of NOLs, as
well as other tax attributes,  following  significant  changes in ownership of a
corporation's stock, as defined in the Code. Investors are cautioned that future
events beyond the control of the Company could reduce or eliminate the Company's
ability to utilize the tax benefits of its NOLs.  Future ownership changes under
Section  382 will  require a new  Section 382  computation  which could  further
restrict the use of the NOLs. In addition,  the Section 382 limitation  could be
reduced to zero if the  Company  fails to satisfy  the  continuity  of  business
enterprise requirement for the two-year period following an ownership change.

 Liquidity and Capital Resources

     The Company's growth has been funded through a combination of equity,  debt
and lease financing.  As of December 31, 1997, the Company had current assets of
$310.2  million,   including  $217.0  million  of  cash,  cash  equivalents  and
short-term investments available for sale, which exceeded current liabilities of
$99.3 million,  providing working capital of $210.9 million. The Company invests
excess funds in short-term,  interest-bearing  investment-grade securities until
such funds are used to fund the capital  investments  and operating needs of the
Company's business.  The Company's short term investment  objectives are safety,
liquidity and yield, in that order.

 Cash Used By Operating Activities

     The Company's operating  activities used $42.8 million and $43.4 million in
fiscal 1995 and 1996, respectively,  $4.6 million and $8.6 million for the three
months ended  December 31, 1995 and 1996,  respectively,  and $127.0 million for
fiscal 1997.  Cash used by operations is primarily due to net losses,  which are
partially  offset by non-cash  expenses,  such as depreciation  and amortization
expense, deferred interest expense,  preferred dividends on subsidiary preferred
securities and changes in working capital items.

     The  Company  expects to  continue  to  generate  negative  cash flows from
operating  activities  while it emphasizes  the  development,  construction  and
expansion of its Telecom Services business. Consequently, it does not anticipate
that  cash  provided  by  operations   will  be  sufficient  to  fund  operating
activities,  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  supporting its Telecom  Services
networks,  any or all of which may not occur, the Company  anticipates that cash
used by operating activities will continue to improve in the near term.

 Cash Used By Investing Activities

     Cash used by investing activities was $71.6 million and $135.2 million (net
of $21.6  million  received  in  connection  with the sale of certain  satellite
equipment,  including  four  teleports)  in fiscal 1995 and 1996,  respectively,
$25.2   million  (net  of  $21.1  million   received  in  connection   with  the
aforementioned  equipment  sale) and $82.3  million for the three  months  ended
December 31, 1995 and 1996,  respectively,  and $429.9  million for fiscal 1997.
Cash used by investing  activities includes cash expended for the acquisition of
property,  equipment  and other assets of $50.1  million and $122.3  million for
fiscal 1995 and 1996, respectively,  and $26.8 million and $50.8 million for the
three months ended December 31, 1995 and 1996, respectively,  and $269.6 million
for  fiscal  1997.  Additionally,  cash used by  investing  activities  includes
payments for  construction  of the Company's new  headquarters  of $1.5 million,
$7.9 million and $29.4 million for fiscal 1996,  the three months ended December
31, 1996 and fiscal 1997, respectively. The Company will continue to use cash in
investing  activities in 1998 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 and through the issuance of
debt or  warrants of $38.7  million  and $55.0  million in fiscal 1995 and 1996,
respectively, $0.1 million and $19.5 million for the three months ended December
31, 1995 and 1996, respectively, and zero for fiscal 1997.

 Cash Provided (Used) By Financing Activities

     Financing  activities  provided $377.8 million and $360.2 million in fiscal
1995 and 1996,  respectively,  used $8.4  million and $0.2  million in the three
months ended  December  31, 1995 and 1996,  respectively,  and  provided  $315.7
million in fiscal 1997. Cash provided by financing activities primarily includes
cash received in connection  with the private  placement of units  consisting of
the 13 1/2% Senior Discount Notes due 2005 (the "13 1/2% Notes") and warrants in
August 1995,  the 12 1/2% Notes and the 14 1/4%  Preferred  Stock in April 1996,
the 11 5/8%  Notes  and the 14%  Preferred  Stock in  March  1997 and the 6 3/4%
Preferred Securities in September and October 1997.  Historically,  the funds to
finance the  Company's  business  acquisitions,  capital  expenditures,  working
capital  requirements and operating losses have been obtained through public and
private  offerings  of  ICG  and  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.

     On March 11, 1997,  Holdings completed a private placement of 11 5/8% Notes
and 100,000  shares of 14%  Preferred  Stock for net  proceeds of  approximately
$192.4 million.  The Company believes the net proceeds of the private  placement
will improve its operating and financial  flexibility over the near term because
(a) the 11 5/8% Notes do not require the payment of cash interest until 2002 and
(b)  Holdings  has the option to pay  dividends  on the 14%  Preferred  Stock in
additional  shares of 14% Preferred  Stock prior to 2002 and the Preferred Stock
is not mandatorily redeemable until 2008.

     The 11 5/8% Notes are unsecured senior obligations of Holdings  (guaranteed
by ICG) that  mature  on March 15,  2007.  Interest  will  accrue at 11 5/8% per
annum,  beginning March 15, 2002, and is payable each March 15 and September 15,
commencing  September  15,  2002.  Dividends  on the  14%  Preferred  Stock  are
cumulative at a rate of 14% per annum and are payable  quarterly in arrears each
March 15, June 15,  September 15 and December 15,  commencing June 15, 1997. The
14%  Preferred  Stock has a  liquidation  preference  of $1,000 per share,  plus
accrued and unpaid  dividends,  and is  mandatorily  redeemable in 2008. The 14%
Preferred  Stock is  exchangeable,  at the option of  Holdings,  into 14% senior
subordinated  exchange  debentures  of Holdings due 2008,  at any time after the
exchange is permitted under certain indenture restrictions.

     On  September  24 and  October 3, 1997,  ICG  Funding  completed  a private
placement  (guaranteed by ICG) of 2,645,000 6 3/4% Preferred  Securities for net
proceeds,  after underwriting costs, of approximately $127.6 million.  Dividends
on the 6 3/4%  Preferred  Securities  are  payable  quarterly  in  arrears  each
February 15, May 15, August 15 and November 15, and commenced November 15, 1997.
The dividend is payable in cash through November 15, 2000, and in cash or shares
of ICG  common  stock,  at the  option of ICG  Funding,  thereafter.  The 6 3/4%
Preferred  Securities  have a liquidation  preference of $50 per security,  plus
accrued and unpaid dividends, and are mandatorily redeemable in 2009. The 6 3/4%
Preferred  Securities  are  exchangeable  at any time prior to November 15, 2009
into shares of ICG Common  Stock at a rate of 2.0812  shares of Common Stock per
preferred security or $24.025 per share.

                                       51


     As of December 31, 1997,  an aggregate of  approximately  $60.2  million of
capitalized  lease  obligations  was due  prior  to  December  31,  2001  and an
aggregate  accreted value of approximately  $887.5 million was outstanding under
the 13 1/2% Notes,  the 12 1/2% Notes and the 11 5/8%  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 March 15,
2002 and  mature on March 15,  2007.  The 6 3/4%  Preferred  Securities  require
payments of  dividends to be made in cash and are being paid  currently  through
November  15,  2000.  In  addition,  the  14%  Preferred  Stock  and the 14 1/4%
Preferred Stock require payment of dividends to be made in cash commencing June
15, 2002 and August 1, 2001, respectively.  As of December 31, 1997, the Company
had $7.9 million of other  indebtedness  outstanding.  The Company may also have
additional  payment  obligations  prior to such time, the amount of which cannot
presently be determined.  The Company's cash on hand and amounts  expected to be
available through vendor financing  arrangements  will provide  sufficient funds
necessary for the Company to expand its Telecom  Services  business as currently
planned and to fund its  operating  deficits  through the first quarter of 1999.
With respect to  indebtedness  outstanding on December 31, 1997, the Company has
cash interest  payment  obligations  of  approximately  $113.3  million in 2001,
$158.0  million in 2002 and $168.1  million in 2003.  With  respect to preferred
securities currently  outstanding,  the Company has cash dividend obligations of
approximately  $8.9  million in each of 1998,  1999 and 2000,  $21.5  million in
2001, $57.0 million in 2002 and $70.9 million in 2003. Accordingly,  the Company
may  have  to  refinance  a  substantial   amount  of  indebtedness  and  obtain
substantial additional funds prior to March 2001. The Company's ability to do so
will  depend on,  among  other  things,  its  financial  condition  at the time,
restrictions in the instruments  governing its indebtedness,  and other factors,
including market conditions,  beyond the control of the Company. There can be no
assurance  that  the  Company  will  be  able to  refinance  such  indebtedness,
including such capitalized  leases,  or obtain such additional funds, and if the
Company is unable to effect such  refinancings or obtain  additional  funds, the
Company's ability to make principal and interest payments on its indebtedness or
make  payments  of cash  dividends  on,  or the  mandatory  redemption  of,  its
preferred securities, would be adversely affected.

     On February 12, 1998,  ICG  Services  completed a private  placement of 10%
Senior Discount Notes due 2008 for net proceeds,  after  underwriting  costs, of
approximately $291.6 million.  Interest will accrue at 10% per annum,  beginning
February 15, 2003,  and is payable  each  February 15 and August 15,  commencing
August 15, 2003. The Notes will be redeemable at the option of ICG Services,  in
whole or in  part,  on or after  February  15,  2003.  

 Capital Expenditures

     The  Company  expects to  continue  to  generate  negative  cash flows from
operating  activities  over  the near  term  while  it  emphasizes  development,
construction  and expansion of its business and until the Company  establishes a
sufficient  revenue-generating customer base. The Company's capital expenditures
(including  assets  acquired  under capital  leases and  excluding  payments for
construction  of the Company's new  headquarters)  were $88.7 million and $177.3
million for fiscal 1995 and 1996, respectively,  $26.9 million and $70.3 million
for the three months ended December 31, 1995 and 1996, respectively,  and $269.6
million for fiscal 1997. 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 $450.0
million during 1998,  including capital  expenditure  requirements of NETCOM. To
facilitate  the  expansion  of its services and networks the Company has entered
into equipment purchase  agreements with various vendors under which the Company
must  purchase a substantial  amount of equipment and other assets,  including a
full  range of  switching  systems,  fiber  optic  cable,  network  electronics,
software  and  services.  Actual  capital  expenditures  will depend on numerous
factors,  including certain factors beyond the Company's control.  These factors
include the nature of future expansion and acquisition  opportunities,  economic
conditions, competition, regulatory developments and the availability of equity,
debt and lease financing.

                                       52


 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
acquisitions 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 capitial expenditures,
it has other cash  commitments  as described in the  footnotes to the  Company's
audited Consolidated Financial Statements for the fiscal year ended December 31,
1997 included elsewhere herein.

     In view of the anticipated  negative cash flows from operating  activities,
the continuing development of the Company's products and services, the expansion
of  existing  networks  and  the  construction,  leasing  and  licensing  of new
networks, the Company will require additional amounts of cash in the future from
outside sources. Management believes that the Company's cash on hand and amounts
expected to be available  through  vendor  financing  arrangements  will provide
sufficient  funds  necessary  for the  Company  to expand its  Telecom  Services
business as currently  planned and to fund its  operating  deficits  through the
first quarter of 1999. Additional sources of cash may include public and private
equity and debt financings,  sales of non-strategic  assets,  capitalized leases
and other financing arrangements.  The Company may require additional amounts of
equity  capital  in the near term.  In the past,  the  Company  has been able to
secure sufficient  amounts of financing to meet its capital  expenditure  needs.
There can be no assurance  that  additional  financing  will be available to the
Company or, if  available,  that it can be obtained on terms  acceptable  to the
Company.

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

Year 2000 Compliance

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

Accounting Change

     During  fiscal  1996,  the  Company  changed its method of  accounting  for
long-term  telecom  services  contracts.  Under  the  new  method,  the  Company
recognizes  revenue as services  are provided  and  continues  to charge  direct
selling  expenses  to  operations  as  incurred.   The  Company  had  previously
recognized  revenue  in an  amount  equal to the  noncancelable  portion  of the
contract,  which is a minimum of one year on a three-year or longer contract, at
the inception of the contract and upon activation of service to the customer, to
the extent of direct  installation  and selling  expense  incurred in  obtaining
customers  during the  period in which  such  revenue  was  recognized.  Revenue
recognized in excess of normal monthly  billings  during the year was limited to
an amount  which did not exceed  such  installation  and  selling  expense.  The
remaining  revenue  from the  contract  had  been  recognized  ratably  over the
remaining  noncancelable  portion of the contract.  The Company believes the new
method is  preferable  because it  provides  a better  matching  of revenue  and
related  operating  expenses and is more consistent  with  accounting  practices
within the telecommunications industry.

     As required by generally accepted  accounting  principles,  the Company has
reflected  the  effects of the change in  accounting  as if such change had been
adopted as of October 1, 1995.  The Company's  results for fiscal 1996 include a
charge of $3.5 million ($0.13 per share)  relating to the  cumulative  effect of
this change in  accounting  as of October 1, 1995.  The effect of this change in
accounting was not significant  for fiscal 1996. If the new revenue  recognition
method had been  applied  retroactively,  Telecom  Services  revenue  would have
decreased   by  $0.5  million  and  $0.7  million  for  fiscal  1994  and  1995,
respectively.  See  the  Company's  Consolidated  Financial  Statements  and the
related notes thereto contained elsewhere in this Annual Report.

 New Accounting Standard

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

ITEM 11.  EXECUTIVE COMPENSATION

Director Compensation

     ICG compensates its non-employee Directors $250 for telephonic meetings and
$2,500 for each Board of Directors'  meeting or committee meeting  attended,  or
$500 for committee  meetings  attended in conjunction with a Board of Directors'
meeting, plus reimbursement of expenses. In addition,  the Chairman of the Board
receives an annual fee of $80,000 payable in quarterly  installments.  In fiscal
1996, all non-employee  Directors of ICG were granted options to purchase 20,000
shares of Common  Stock  under  ICG's 1995  Stock  Option  Plan,  and during the
transition   period  from  October  1,  1996  through  December  31,  1996,  all
non-employee  Directors of ICG were granted  options to purchase 5,000 shares of
Common Stock under ICG's 1996 Stock Option Plan (the "1996 Plan"). On January 1,
1997, all non-employee  Directors of ICG were granted options to purchase 20,000
shares of Common  Stock under the 1996 Plan,  which vested as to 5,000 shares at
the end of each fiscal quarter. On June 17, 1997, all non-employee  Directors of
ICG were granted an additional  option to purchase  5,000 shares of Common Stock
under the 1996 Plan. On January 1, 1998, all non-employee  Directors of ICG were
granted  options to purchase  20,000 shares of Common Stock under the 1996 Plan,
which vest as to 5,000 shares at the end of each fiscal quarter.

Compensation Committee Interlocks and Insider Participation

     The  Compensation   Committee   presently  consists  of  four  non-employee
Directors:  William J.  Laggett,  Chairman of the Board of  Directors,  Harry R.
Herbst, Walter Threadgill and Leontis Teryazos.

Board Compensation Committee Report on Executive Compensation

     The  Compensation  Committee  of the Board of Directors of the Company (the
"Compensation Committee") evaluates compensation levels of senior management and
evaluates the various factors  affecting  compensation of the Company's  highest
paid officers.  The  Compensation  Committee  believes that  compensation to the
Company's  executive  officers  should  be  designed  to  encourage  and  reward
management's  efforts to further strengthen the Company's business and to create
added value for stockholders.  Such a compensation  program helps to achieve the
Company's business and financial  objectives and also provides incentives needed
to attract  and retain  well-qualified  executives.  The  Company  operates in a
competitive  marketplace and needs to attract and retain highly qualified senior
management and executive personnel in order for the Company to achieve its goals
of  continuing  to develop new services and expanding  into new  businesses  and
markets.  The  Compensation  Committee  attributes a substantial  portion of the
Company's overall  performance,  as well as the individual  contributions of the
executive officers, to the executive officers' compensation.
<PAGE>
                                       61
  
     The  Company  has  employment  agreements  with  several  of its  executive
officers.  See  "Executive  Employment  Contracts"  for  descriptions  of  those
agreements.  All senior  management,  except for J. Shelby Bryan,  President and
Chief Executive  Officer,  are  compensated  with a base salary and an incentive
bonus.  The base salaries are intended to compensate  these executives for their
ongoing leadership skills and management  responsibility.  The incentive bonuses
are dependent  upon  individual  performance.  For purposes of  determining  the
bonuses, the Compensation Committee evaluates the accomplishment of goals set at
the start of each fiscal year and compares  the  Company's  performance  in each
year to the prior year. Based on the progress of the Company during fiscal 1997,
Chairman Laggett recommended,  and the Compensation Committee approved,  bonuses
for the named  executive  officers of the  Company.  See  "Summary  Compensation
Table" for the bonuses paid to executive officers.

     The compensation of the Company's President and Chief Executive Officer, J.
Shelby  Bryan,  is set  forth in his  employment  contract.  His base  salary is
computed  as: the sum of (x) one percent (1%) of the increase in Revenues of the
Company for such month over  Revenues of the Company for the  immediately  prior
month and (y) three  percent  (3%) of the  increase  in Earnings  Before  Income
Taxes,  Depreciation and  Amortization  ("EBITDA") of the Company for such month
over EBITDA of the Company for the  immediately  prior month.  In addition,  Mr.
Bryan receives other benefits. See "Summary Compensation Table" for the type and
amount  of  these  payments.   The  Compensation  Committee  believes  that  the
compensation paid to Mr. Bryan is a suitable  compensation  package based on Mr.
Bryan's experience in the  communications  industry and because his compensation
is directly tied to the performance of the Company.

     In addition,  the Stock Option  Committee  awarded stock options to certain
employees  of the  Company,  including  executive  officers.  These  grants were
related to the executive officers'  performance in fiscal 1996 and as incentives
for continued  efforts and success and were based on individual  performance and
responsibility.  The Compensation Committee believes that stock options serve as
important  long-term  incentives  for executive  officers by  encouraging  their
continued   employment  and  commitment  to  the  Company's   performance.   The
Compensation  and Stock Option  Committees do not consider the number of options
currently  held by all  executive  officers  in  determining  individual  grants
because such  consideration  could  create an incentive to exercise  options and
sell the  underlying  stock.  See  "Summary  Compensation  Table"  for the stock
options granted to the executive officers.

     The  Compensation  Committee has reviewed the compensation of the Company's
executive  officers and has concluded that their  compensation was reasonable in
view of the Company's  performance.  The  Compensation  Committee  observed that
revenue increased $82.7 million,  approximately  43%, in fiscal 1997 as compared
with the 12 months ended  December 31, 1996.  The Company's  networks have grown
from  approximately  2,385  operational  fiber route  miles at December  1996 to
approximately  3,043  operational  miles at the end of fiscal 1997.  The Company
also  raised net  proceeds of $320.0  million  from the  issuance  of  preferred
securities  and notes during  fiscal 1997.  These  accomplishments  exceeded the
Company's  objectives for fiscal 1997. The Compensation  Committee believes that
the Company  appropriately  awarded its executive  officers for their short- and
long-term efforts.
<PAGE>
                                       62

     The Compensation  Committee  continually  evaluates the compensation of the
Company's  executive  officers,  including  assessing  compensation  reports for
comparable companies and for the  telecommunications  industry. The Compensation
Committee believes that maintaining suitable executive  compensation programs is
necessary  to  support  the  future  development  of the  Company  and growth in
stockholder value.

Executive Compensation

     The  following  table  provides  certain  summary  information   concerning
compensation  paid or  accrued by the  Company  and its  subsidiaries,  to or on
behalf of J. Shelby Bryan, the Company's  President and Chief Executive Officer,
the four other most highly compensated executive officers of the Company and one
additional officer for whom disclosure would have been required but for the fact
that the  individual  was not serving as executive  officer at December 31, 1997
(the "Named  Officers") for the fiscal years ended December 31, 1997,  September
30,  1996 and 1995.  Due to the  Company's  change in year end during  1996 from
September 30 to December 31,  additional  amounts are shown below in the Summary
Compensation Table for the 12 months ended December 31, 1996 and are referred to
in such  tables  as  "1996T."  The  Company  has not  maintained  any  long-term
incentive plans and the Company has not granted stock appreciation rights.

                         Ten-Year Option/SAR Repricings

Report on Repricing of Options/SARs
     
     The Stock  Option  Committee  of the Board of Directors of the Company (the
"Committee") is responsible for  administering the Company's Stock Option Plans,
as well as granting any stock options  thereunder.  The Committee is composed of
four independent, non-employee directors.

     In 1996, the Company  established  the 1996 Stock Option Plan (the "Plan").
Prior to that time, the Plan was known as the IntelCom  Group Inc.  Restated and
Amended 1995 Stock Option Plan (the "IntelCom Plan").  Effective as of August 2,
1996, the Company assumed sponsorship of, and immediately thereafter amended and
restated, the IntelCom Plan. The Plan constitutes a continuation of the IntelCom
Plan, as assumed by the Company.

     The purpose of the Plan is to promote  success and enhance the value of the
Company by linking the personal interest of participants to those of the Company
stockholders  by  providing  participants  with  an  incentive  for  outstanding
performance.  The Plan is further  intended to assist the Company in its ability
to  motivate,  and retain the services of,  participants  upon whose  judgement,
interest and special effort the successful  conduct of its operations is largely
dependent.  Stock options are awarded by the Committee according to the terms of
the Plan. Up to an aggregate number of 2,500,000 shares may be granted under the
Plan, reduced by the number of Common Shares of IntelCom  represented by options
granted to  individuals  under the IntelCom  Plan prior to August 2, 1996.  When
awarding stock options,  the Committee takes into consideration the individual's
past performance and contribution to the Company, as well as future potential.

     In April 1997, the Committee  considered  repricing  certain existing stock
options  that, as a result of recent stock  declines in the Company's  industry,
had an exercise  price in excess of the then fair market value of the  Company's
Common Stock. Specifically, approximately 154,000 stock options granted on March
7, 1996 as part of employee bonus compensation had an exercise price of $15.875,
approximately  219,000  options  granted in connection with recent new hires had
exercise prices ranging from $16.25 to $26.25, and approximately 225,000 options
granted  as part of  employee  bonus  compensation  on October  22,  1996 had an
exercise  price of $19.125 per share.  At those prices,  the Committee  believed
that the  options  were  not able to  effectively  serve as  incentives  for the
employees and that, in the current  competitive market place, the Company needed
to have a strong  incentive  compensation  program  in place in order to retain,
keep and motivate its employees.

     Consequently,  the  Committee  approved the  repricing  of all  outstanding
employee  stock options  previously  granted under the stock option plans of the
Company  (and  its   predecessor,   IntelCom  Group  Inc.)  which  options  were
exercisable  at  prices  at or in excess of  $15.875  per share  (the  "Eligible
Options").  The  repricing was  accomplished  through an offer to all holders of
Eligible  Options to exchange  the Eligible  Options for new stock  options (the
"Repriced  Options"),  as of April 19, 1997, under the same terms and conditions
(including vesting) contained in the stock option plan as originally granted the
Eligible Option.  The Repriced Options are exercisable at a price of $10.375 per
share,  which was the closing price of a common share of Common Stock,  $.01 par
value, of the company on the Nasdaq National Market on April 19, 1997.

covenant.

     The Company's  employment  agreement with Mr. Grenfell  originally provided
for an initial  two-year term which commenced  November 1, 1995. Upon completion
of the first 12 months of the initial term, the agreement  automatically renewed
and will continue to automatically renew from month-to-month such that 12 months
remain in the term. The agreement may be terminated  upon 30 days written notice

ITEM 13. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

     To facilitate the  acquisition of certain  competitive  access networks and
satellite  services  businesses which held common carrier radio licenses subject
<PAGE>
                                       73

to foreign  ownership  restrictions,  the common  carrier  licenses  used by the
Company's   teleports  and  the  wireless   competitive   access  networks  were
controlled,  prior to November 30, 1997, by Teleport Transmissions Holdings Inc.
("TTH"),  a corporation owned one-third each by U.S. Director William J. Laggett
and two former Directors.  TTH's  subsidiaries gave 15-year  promissory notes to
ICG to acquire the FCC  licenses.  After  receipt of approval  from the FCC, the
Company  exercised  its option on November  30, 1997 to have the common  carrier
licenses transferred back to the Company. Upon completion of the transfer of the
licenses,  the promissory notes were canceled.  In fiscal 1997, the Company paid
or accrued  approximately  $0.6 million to TTH's subsidiaries for common carrier
services,  and the Company received from TTH's  subsidiaries  approximately $2.4
million  as  payment  in  full on the  promissory  notes,  management  services,
equipment leases and technical support. In addition,  approximately $1.1 million
of the  note  balances  were  canceled  due  to the  sale  of  the  licenses  in
conjunction   with  the   sale  of  four  of  the   Company's   teleports.   See
"Business-Regulation."

     Holdings-Canada and International  Communications Consulting,  Inc. ("ICC")
have  entered into a three-year  consulting  agreement  whereby ICC will provide
various consulting services to the Company through December 1999 in exchange for
approximately  $4.2 million in consulting fees to be paid during the term of the
agreement.  During  fiscal  1997,  the Company paid  approximately  $1.1 million
related to this consulting  agreement.  William W. Becker, a former Director and
stockholder of the Company, is President and Chief Executive Officer of ICC.

     As part of a resolution  and  settlement  of certain  transactions  in 1995
between the Company and the Becker Group of Companies  (the "Becker  Group"),  a
company founded by William W. Becker, the Company was assigned a note receivable
in the amount of $200,000,  which had previously been advanced to John D. Field,
a former  executive  officer  of the  Company,  by the  Becker  Group.  The note
receivable  is  evidenced  by a  promissory  note from Mr.  Field to the Company
payable on demand, which bears interest at a rate of 7% per annum.

     In order to  facilitate  the  relocation  of William J.  Maxwell,  a former
executive  officer of the Company,  the Company advanced $200,000 to Mr. Maxwell
in April 1994  pursuant  to a  promissory  note  payable on demand  which  bears
interest  at a rate of 7% per annum.  In March 1998,  the April 1994  promissory
note was replaced with a new  promissory  note for $125,000 which is due in full
on September 30, 1998.

                          Independent Auditors' Report




The Board of Directors and Stockholders
ICG Communications, Inc.:

We  have  audited  the   accompanying   consolidated   balance   sheets  of  ICG
Communications,  Inc. and  subsidiaries as of December 31, 1996 and 1997 and the
related consolidated  statements of operations,  stockholders' equity (deficit),
and cash flows for the fiscal  years  ended  September  30,  1995 and 1996,  the
three-month  period ended  December 31, 1996, and the fiscal year ended December
31, 1997. These consolidated  financial statements are the responsibility of the
Company's  management.  Our  responsibility  is to  express  an opinion on these
consolidated financial statements based on our audits.

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

In our opinion, the consolidated  financial statements referred to above present
fairly, in all material respects,  the financial position of ICG Communications,

ICG COMMUNICATIONS, INC.
AND SUBSIDIARIES

Notes to Consolidated Financial Statements
December 31, 1996 and 1997
- -------------------------------------------------------------------------------

(1)  Organization and Nature of Business

     ICG Communications,  Inc., a Delaware corporation ("ICG"), was incorporated
     on April 11, 1996, for the purpose of becoming the new publicly-traded U.S.
     parent  company  of  ICG  Holdings  (Canada),   Inc.,  a  Canadian  federal
     corporation ("Holdings-Canada"), ICG Holdings, Inc., a Colorado corporation
     ("Holdings"), and its subsidiaries.  Pursuant to a Plan of Arrangement (the
     "Arrangement"),  which was approved by Holdings-Canada shareholders on July
     30,  1996,  and by the  Ontario  Court of Justice  on August 2, 1996,  each
     shareholder  of   Holdings-Canada   exchanged  their  common  shares  on  a
     one-for-one  basis for either (i) shares of $.01 par value  common stock of
     ICG (the "Common Stock"),  or (ii) Class A common shares of Holdings-Canada
     (which are  exchangeable at any time on a one-for-one  basis into shares of
     ICG Common Stock). On August 2, 1996, 28,795,132,  or approximately 98%, of
     the total issued and  outstanding  common  shares of  Holdings-Canada  were
     exchanged  for an equal  number  of  shares  of  Common  Stock  of ICG.  In
     accordance with generally accepted accounting  principles,  the Arrangement
     was accounted for in a manner  similar to a pooling of interests  since ICG
     and  Holdings-Canada  had  common  shareholders,  and the  number of shares
     outstanding and the weighted average number of shares  outstanding  reflect
     the equivalent shares outstanding for the combined companies.  On September
     17, 1997,  ICG formed a new special  purpose  entity,  ICG Funding,  LLC, a
     Delaware limited liability company and wholly owned subsidiary of ICG ("ICG
     Funding").  ICG and its subsidiaries  are  collectively  referred to as the
     "Company."

     The Company's principal business activity is  telecommunications  services,
     including Telecom Services, Network Services and Satellite Services, and as
     of January 21, 1998, the Company also began  providing  Internet  Services,
     through its recently  acquired  subsidiary,  NETCOM  On-Line  Communication
     Services,  Inc.  ("NETCOM").  Telecom  Services  consists of the  Company's
     competitive  local exchange  carrier  operations  which provide services to
     business end users, long distance carriers and resellers.  Network Services
     supplies information  technology services and selected networking products,
     focusing on network  design,  installation,  maintenance  and support for a
     variety  of end  users,  including  Fortune  1000  firms  and  other  large
     businesses and  telecommunications  companies.  Satellite Services provides
     satellite  voice  and  data  services  to  major  cruise  ship  lines,  the
     commercial  shipping  industry,  yachts,  the U.S.  Navy and  offshore  oil
     platforms.  The  Company  intends  to  dispose  of its  Satellite  Services
     operations to better focus on its core Telecom  Services unit,  although it
     has not entered into a formal arrangement for such dispostion. Beginning in
     1998, the Company's Internet Services

(1)  Organization and Nature of Business

     includes Internet access,  World Wide Web (the "Web") site hosting services
     and other value-added  connectivity services,  which are primarily targeted
     to small and medium-sized  business customers in the United States,  Canada
     and the United Kingdom.

(2)  Summary of Significant Accounting Policies

     (a)  Basis of Presentation

          The accompanying  consolidated financial statements have been prepared
          in accordance with  accounting  principles  generally  accepted in the
          United  States,  and  include  the  accounts  of the  Company  and its
          majority and wholly owned subsidiaries. Financial information prior to
          the  completion of the  Arrangement  on August 2, 1996  represents the
          financial  position and results of operations of  Holdings-Canada  and
          Holdings, which are considered to be predecessor entities to ICG.

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

     (b)  Change in Fiscal Year End

          The Company  changed its fiscal year end to December 31 from September
          30,  effective  January 1, 1997.  References to fiscal 1995,  1996 and
          1997  relate  to the  years  ended  September  30,  1995  and 1996 and
          December 31, 1997, respectively.

          Unaudited consolidated statements of operations and cash flows for the
          three  months  ended  December  31,  1995  have been  included  in the

(2)  Summary of Significant Accounting Policies (continued)

     (c)  Cash Equivalents and Short-term Investments Available for Sale

          The Company  considers  all highly  liquid  investments  with original
          maturities of three months or less to be cash equivalents. 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.  The Company carries all
          cash   equivalents   and  short-term   investments   at  cost,   which
          approximates fair value.

     (d)  Inventory

          Inventory,  consisting of satellite systems equipment and equipment to
          be utilized in the installation of  communications  systems,  services
          and  networks  for  customers,  is  recorded  at the  lower of cost or
          market, using the first-in, first-out method of accounting for cost.

     (e)  Investments

          Investments  in joint  ventures  are  accounted  for using the  equity
          method,  under which the Company's  share of earnings or losses of the
          joint  ventures are reflected in operations and dividends are credited
          against the investment when received.  Losses  recognized in excess of
          the Company's  investment  due to  additional  investment or financing
          requirements,  or  guarantees,  are  recorded  as a  liability  in the
          consolidated financial statements.  Other investments  representing an
          interest of 20% or more,  but less than 50%, are  accounted  for using
          the equity method of accounting. Investments of less than a 20% equity
          interest are accounted  for using the cost method,  unless the Company
          exercises  significant influence and/or control over the operations of
          the investee company, in which case the equity method is used.

(2)  Summary of Significant Accounting Policies (continued)

     (f)  Property and Equipment

          Property and equipment are stated at cost.  Costs of construction  are
          capitalized,   including   interest  costs  related  to  construction.
          Equipment held under capital leases is stated at the lower of the fair
          value of the  asset or the net  present  value  of the  minimum  lease
          payments  at the  inception  of the lease.  For  equipment  held under
          capital  leases,  depreciation  is  provided  using the  straight-line
          method over the  estimated  useful lives of the assets  owned,  or the
          related lease term, whichever is shorter.

          Estimated  useful lives of major  categories of property and equipment
          are as follows:  Office furniture and equipment 3 to 7 years Buildings
          and  improvements  31.5 years  Machinery  and  equipment  3 to 8 years
          Switch equipment 10 years Fiber optic transmission system 20 years

          The  Company   capitalizes  the  direct  costs   associated  with  the
          installation of dial tone customers'  service,  including labor and an
          allocation  of  overhead  costs,  and  amortizes  these costs over two
          years, the estimated average customer contract term.

     (h)  Use of Estimates

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

     (i)  Revenue Recognition

          The Company recognizes Telecom Services and Satellite Services revenue
          as services  are  provided  and  charges  direct  selling  expenses to
          operations as incurred.  Revenue from Network  Services  contracts for
          the design and  installation  of  communication  systems and networks,
          which are generally  short-term in duration,  is recognized  using the
          percentage of completion method of accounting.  Maintenance revenue is
          recognized as services are provided.  Uncollectible  trade receivables
          are accounted for using the allowance method.

          Revenue  which has been  earned  under the  percentage  of  completion
          method,  but has not  been  billed  to the  customer  is  included  in
          receivables-revenue earned, but unbilled in the consolidated financial
          statements.  Deferred  revenue  includes  monthly advance  billings to
          customers  for  certain  services  provided by the  Company's  Telecom
          Services and Satellite  Services,  as well as Network Services revenue
          which has been billed to the  customer  in  compliance  with  contract
          terms, but not yet earned under the percentage of completion method.

          Prior to January 1, 1996,  the  Company  recognized  Telecom  Services
          revenue  in an  amount  equal  to the  non-cancelable  portion  of the
          contract,  which is a minimum  of one year on a  three-year  or longer
          contract,  at the  inception of the contract  and upon  activation  of
          service  to the  customer  to the  extent of direct  installation  and
          selling expenses incurred in obtaining  customers during the period in
          which such revenue

(2)  Summary of Significant Accounting Policies (continued)

          was  recognized.  Revenue  recognized  in  excess  of  normal  monthly
          billings during the year was limited to an amount which did not exceed
          such installation and selling expense.  The remaining revenue from the
          contract  was  recognized  ratably over the  remaining  non-cancelable
          portion  of the  contract.  The  Company  believes  the new  method is
          preferable  because it  provides  a better  matching  of  revenue  and
          related  operating  expenses and is more  consistent  with  accounting
          practices  within the  telecommunications  industry.  As  required  by
          generally accepted  accounting  principles,  the Company has reflected
          the  effects of the change in  accounting  as if such  change had been
          adopted  as of October 1, 1995,  and has  included  in the  results of
          operations  for fiscal  1996 a charge of  approximately  $3.5  million
          relating to the cumulative effect of this change in accounting.  Other
          than the cumulative  effect of adopting this new method of accounting,
          the effect of this change in accounting for the periods  presented was
          not significant.

     (j)  Income Taxes

          The  Company  accounts  for  income  taxes  under  the  provisions  of
          Statement of Financial  Accounting  Standards No. 109,  Accounting for
          Income Taxes ("SFAS  109").  Under the asset and  liability  method of
          SFAS 109,  deferred tax assets and  liabilities are recognized for the
          future  tax  consequences  attributable  to  differences  between  the
          financial   statement   carrying   amounts  of  existing   assets  and
          liabilities  and their  respective tax bases.  Deferred tax assets and
          liabilities  are measured using enacted tax rates expected to apply to
          taxable income in the years in which those  temporary  differences are
          expected to be  recovered  or settled.  Under SFAS 109,  the effect on
          deferred  tax  assets  and  liabilities  of a change  in tax  rates is
          recognized in income in the period that includes the enactment date.

     (k)  Loss Per Share

          Loss per share is  calculated by dividing the net loss by the weighted
          average  number  of shares  outstanding.  Weighted  average  number of
          shares  outstanding  for fiscal year 1995 and the three  months  ended
          December  31,  1995  represents  outstanding   Holdings-Canada  common
          shares. Weighted average number of shares outstanding for fiscal 1996,
          the three  months ended  December 31, 1996 and fiscal 1997  represents
          Holdings-Canada common shares outstanding for the period October 1,

(2)  Summary of Significant Accounting Policies (continued)

          1995  through  August 2,  1996,  and  combined  ICG  Common  Stock and
          Holdings-Canada  Class A common  shares  outstanding  for the  periods
          subsequent to August 5, 1996.

          In February  1997,  the Financial  Accounting  Standards  Board issued
          Statement  No. 128,  Earnings Per Share ("SFAS 128") which revises the
          calculation and presentation provisions of Accounting Principles Board
          Opinion No. 15 and related interpretations. Under SFAS 128, basic loss
          per share is computed on the basis of weighted  average  common shares
          outstanding.  Diluted loss per share considers  potential common stock
          instruments in the  calculation.  The Company adopted SFAS 128 for its
          fiscal year ending  December 31, 1997,  including the  requirement for
          retroactive application. The adoption of SFAS 128 had no effect on the
          Company's  previously reported loss per share.  Potential common stock
          instruments,   which  include   options,   warrants  and   convertible
          subordinated notes and preferred  securities,  are not included in the
          loss per share calculation as their effect is anti-dilutive.

     (l)  Stock-Based Compensation

          The Company  accounts for its  stock-based  employee and  non-employee
          director  compensation  plans using the  intrinsic  value based method
          prescribed by Accounting  Principles Board Opinion No. 25,  Accounting
          for Stock Issued to Employees, and related Interpretations ("APB 25").
          The Company has  provided pro forma  disclosures  of net loss and loss
          per share as if the fair value based  method of  accounting  for these
          plans,  as prescribed by Statement of Financial  Accounting  Standards
          No. 123,  Accounting for Stock-Based  Compensation  ("SFAS 123"),  had
          been applied.  Pro forma  disclosures  include the effects of employee
          and  non-employee  director stock options  granted during fiscal 1996,
          the three months ended December 31, 1996 and fiscal 1997.

     (m)  Impairment of Long-Lived Assets

          The Company provides for the impairment of long-lived  assets pursuant
          to Statement of Financial Accounting Standards No. 121, Accounting for
          the Impairment of Long-Lived  Assets and for  Long-Lived  Assets to Be
          Disposed Of ("SFAS 121") which  requires  that  long-lived  assets and
          certain identifiable intangibles held and used by an

(2)  Summary of Significant Accounting Policies (continued)

          entity be  reviewed  for  impairment  whenever  events or  changes  in
          circumstances  indicate that the carrying value of an asset may not be
          recoverable.   An  impairment   loss  is  recognized   when  estimated
          undiscounted  future cash flows  expected to be generated by the asset
          is less than its carrying value. Measurement of the impairment loss is
          based on the fair value of the asset,  which is  generally  determined
          using  valuation  techniques  such as the discounted  present value of
          expected future cash flows.

     (n)  Reclassifications

          Certain prior period  amounts have been  reclassified  to conform with
          the current period's presentation.

(3)  Business Combinations and Investments

     (a)  Acquisition During Fiscal 1997

          On October 17, 1997, the Company  purchased  approximately  91% of the
          outstanding  capital  stock  of  Communications   Buying  Group,  Inc.
          ("CBG"),  an Ohio based  local  exchange  and  centrex  reseller.  The
          Company paid total consideration of approximately $46.5 million,  plus
          the  assumption  of certain  liabilities.  Separately,  on October 17,
          1997,   the  Company   sold   687,221   shares  of  Common  Stock  for
          approximately $16.0 million to certain shareholders of CBG. Subsequent
          to December 31,1997, the Company purchased the remaining approximately
          9% interest in CBG for approximately $2.9 million in cash.

          The Company  has  accounted  for the  acquisition  under the  purchase
          method of accounting, and accordingly, the operations of CBG have been
          included in the Company's  operations since the acquisition  date. The
          excess  of  the  purchase  price  over  the  fair  value  of  the  net
          identifiable  assets  acquired of $48.8  million has been  recorded as
          goodwill  and is being  amortized  on a  straight-line  basis over six
          years.  Revenue,  net loss and loss per share on a pro forma  combined
          basis are not  significantly  different from the Company's  historical
          results for the periods presented herein.

(3)  Business Combinations and Investments (continued)

     (b)  Acquisitions and Investments During Fiscal 1996

          In January  1996,  the Company  purchased  the  remaining 49% minority
          interest of Fiber Optic  Technologies,  Inc.  ("FOTI"),  making FOTI a
          wholly   owned   subsidiary.   Consideration   for  the  purchase  was
          approximately  $2.0  million  in cash  and  66,236  common  shares  of
          Holdings-Canada  valued  at  approximately  $0.8  million,  for  total
          consideration of approximately $2.8 million.

          In February 1996, the Company  entered into an agreement with Linkatel
          California,   L.P.  ("Linkatel")  and  its  other  partners,  Linkatel
          Communications,  Inc.  and The Copley  Press,  Inc.,  under  which the
          Company acquired a 60% interest in Linkatel for an aggregate  purchase
          price of $10.0  million  in cash and  became  the  general  partner of
          Linkatel.  In April 1996, the  partnership  was renamed ICG Telecom of
          San Diego, L.P.

          In March 1996, the Company acquired a 90% equity interest in MarineSat
          Communications  Network,  Inc.  ("MCN"),  (formally  Maritime Cellular
          Tele-network,   Inc.),  a  Florida-based   provider  of  cellular  and
          satellite   communications  for  commercial  ships,  private  vessels,
          offshore oil platforms and land-based  mobile units, for approximately
          $0.7 million in cash and  approximately  $0.1 million of assumed debt,
          for total  consideration of approximately $0.8 million. In April 1997,
          the Company  received  the  remaining  10%  interest in MCN as partial
          consideration  for the sale of its investment in Mexico. In the fourth
          quarter  of  fiscal  1997,  the  Company   recorded  a  provision  for
          impairment of $2.9 million of its investment in MCN.

          In August  1996,  the  Company  acquired  certain  Signaling  System 7
          ("SS7") assets of Pace Network Services,  Inc. ("Pace"), a division of
          Pace  Alternative  Communications,  Inc. SS7 is used by local exchange
          companies,  long-distance  carriers,  wireless  carriers and others to
          signal between network elements, creating faster call set-up resulting
          in a more  efficient use of network  resources.  The Company paid cash
          consideration  of  $1.6  million  as of  September  30,  1996  and  an
          additional  $1.0  million  in  January  1997,  based on the  operating
          results of the underlying business since the date of acquisition.

(3)  Business Combinations and Investments (continued)

          The  acquisitions  described  above have been  accounted for using the
          purchase  method of accounting  and,  accordingly,  the net assets and
          results of  operations  are  included  in the  consolidated  financial
          statements from the respective dates of acquisition. Revenue, net loss
          and  loss  per  share  on a pro  forma  basis  are  not  significantly
          different  from  the  Company's  historical  results  for the  periods
          presented   herein.   The  aggregate   purchase   price  of  the  1996
          acquisitions,  in which the Company  obtained a controlling  interest,
          was allocated  based on fair values of the underlying  assets acquired
          as follows (in thousands):

          Current assets                                     $   6,563
          Property and equipment                                 7,542
          Other assets, including goodwill                      10,647
          Current liabilities                                     (775)

     (c)  Acquisitions and Investments During Fiscal 1995

          In  January  1995,  the  Company  and an  unaffiliated  entity  formed
          Maritime  Telecommunications Network, Inc. ("MTN") to provide wireless
          communications  through  satellites to the maritime  cruise  industry,
          U.S. Navy vessels and offshore oil platforms. The Company acquired (i)
          approximately  64% of MTN,  (ii)  approximately  $4.4 million in notes
          receivable from MTN and (iii)  consulting and  non-compete  agreements
          valued at an aggregate of  approximately  $0.3 million in exchange for
          (i)  approximately  $9.0  million  in  cash,  (ii) the  surrender  and
          cancellation  of a note to the Company  from the other entity for $0.6
          million plus  interest,  (iii) 408,347  Holdings-Canada  common shares
          valued at  approximately  $5.1 million (of which 256,303 common shares
          were  issued  in the  fourth  quarter  of fiscal  1994),  and (iv) the
          Company's commitment to provide additional convertible working capital
          advances  to MTN as  required  by MTN.  The other  shareholder  of MTN
          contributed the assets of a predecessor business to MTN.

          MTN also assumed  approximately  $2.1 million of  obligations  of such
          predecessor  business.  The Company paid a $0.5  million  finder's fee
          obligation of the  predecessor to a third party.  As part of the terms
          of the original purchase agreement, the

(3)  Business Combinations and Investments (continued)

          Company agreed to purchase, at fair market value, all of the shares of
          MTN that were owned by the minority  shareholders,  upon demand of the
          minority  shareholders,  if  a  transaction  was  not  effected  which
          converted the minority shares into publicly traded  securities or cash
          by January 3, 1998.  As of the current  date,  no such demand has been
          made by the minority shareholders.

          During  fiscal  1995,  the Company  purchased a 58%  interest in Zycom
          Corporation ("Zycom"), an Alberta, Canada corporation whose shares are
          traded on the Alberta Stock Exchange.  Consideration  for the purchase
          was approximately $0.8 million in cash, the conversion of $2.0 million
          in notes receivable,  and the assumption of approximately $0.7 million
          in debt for total  consideration  of  approximately  $3.5 million.  In
          March 1996, the Company acquired an additional  approximate 12% equity
          interest in Zycom by  converting  a $3.2 million  receivable  due from
          Zycom into common  stock.  In the fourth  quarter of fiscal 1997,  the
          Company  recorded a provision  for  impairment  of $2.7 million of its
          investment in Zycom.

          The acquisitions described above were accounted for using the purchase
          method of accounting, and accordingly,  the net assets and the results
          of operations are included in the  consolidated  financial  statements
          from the respective dates of acquisition.  Revenue,  net loss and loss
          per share on a pro forma basis are not  significantly  different  from
          the Company's historical results for the periods presented herein. The
          aggregate  purchase  price of the  1995  acquisitions,  in  which  the
          Company obtained a controlling  interest,  was allocated based on fair
          values of the underlying assets acquired as follows (in thousands):

          Current assets                                    $       1,835
          Property and equipment                                    9,086
          Other assets, including goodwill                         16,986
          Current liabilities                                      (2,764)

          During fiscal 1995, the Company  invested  approximately  $5.2 million
          ($3.9   million   in  cash,   $1.1   million   in  common   shares  of
          Holdings-Canada,  and the conversion of approximately  $0.2 million in
          notes  receivable)  in  StarCom   International   Optics   Corporation
          ("StarCom"),  for which the Company  received a 25% equity interest in
          each of Starcom's  wholly owned  operating  subsidiaries.  In December
          1997, a senior secured  creditor of StarCom  notified the Company that
          it intended to foreclose on its collateral in StarCom,  and in January
          1998, StarCom commenced bankruptcy proceedings.  Based on management's
          estimate of the net realizable  value of its  investment,  the Company
          recorded a provision for  impairment of its investment of $5.2 million
          in fiscal 1997.

     (d)  Investments in Joint Venture and Affiliate

          In September 1992, the Company entered into a joint venture  agreement
          with Greenstar  Technologies  Inc. (now GST  Telecommunications,  Inc.
          ("GST")) to design, construct and operate a competitive access network
          in Phoenix.  The Company and GST each had a 50% equity interest in the
          joint  venture.  All  financing  provided to the joint  venture by the
          Company,  as well as the  recognition  of the  Company's  share of the
          joint venture's losses,  were recorded  according to the equity method
          of accounting.  During fiscal 1996,  the Company  recorded a valuation
          allowance of  approximately  $5.8  million for the amounts  receivable
          arising from advances made to the Phoenix network joint venture, based
          on  management's   estimate  of  the  net  realizable   value  of  the
          receivable.

          In October 1996, the Company sold its interest in the joint venture to
          GST.  The  Company  received   approximately  $2.1  million  in  cash,
          representing  $1.3 million of  consideration  for its 50% interest and
          $0.8 million for equipment and amounts  advanced to the joint venture.
          In addition,  the Company received  equipment with a net book value of
          $2.4 million and assumed  liabilities of $0.3 million.  A gain on sale
          of the joint venture of approximately $0.8 million was recorded in the
          consolidated  financial  statements  during  the  three  months  ended
          December 31, 1996.

     (e)  Merger Subsequent to December 31, 1997

          On January  21,  1998,  the Company  completed  a merger with  NETCOM.
          Located  in San Jose,  California,  NETCOM is a provider  of  Internet
          connectivity  and Web site  hosting  services  and  other  value-added
          Internet  services.   At  the  effective  time  of  the  merger,  each
          outstanding   share  of  NETCOM  common  stock  became   automatically
          convertible into shares of Common Stock at an exchange ratio of 0.8628
          shares of Common  Stock per NETCOM  common  share.  As a result of the
          transaction,  the Company  expects to issue an estimated  10.2 million
          shares of Common Stock for the NETCOM  common  shares  outstanding  on
          January 21, 1998. Cash will be paid in lieu of fractional  shares. The
          Company  will  account  for  the   business   combination   under  the
          pooling-of-interests   method  of  accounting  and  accordingly,   the
          Company's  financial  statements  will  be  restated  to  reflect  the
          operations  of NETCOM  and the  Company  on a  combined  basis for all
          historical periods.

          The following  unaudited pro forma  information  presents the combined
          results of  operations  of the Company  and NETCOM as if the  business
          combination had been  consummated on October 1, 1994. The Company does
          not anticipate any  significant  adjustments to conform the accounting
          policies of NETCOM with those of the Company.

(10) Long-term Debt (continued)

          Approximately  $35.3  million of the  proceeds  from the 1996  Private

          agreement, plus unpaid interest, if any, at the date of redemption.

          The Unit  Warrants  entitle the holder to purchase one common share of

          at the exercise  price of $12.51 per share and are  exercisable at any
          time between August 8, 1996 and August 8, 2005.

          In  connection  with the  issuance of the 13 1/2%  Notes,  the Company
          obtained $6.0 million of interim  financing  from the placement  agent
          and  certain  private  investors  in exchange  for the  issuance of an
          aggregate  of 520,000  Series A Warrants  (see note 12 (c)).  The $6.0
          million  was  repaid  with a  portion  of the  proceeds  from the 1995
          Private  Offering.  As a  result  of  the  repayment  of  the  interim
          financing,  the  value  assigned  to the  Series A  Warrants  totaling
          approximately $3.0 million, representing debt discount, was charged to
          interest expense during the year ended September 30, 1995.

(11) Redeemable Preferred Securities of Subsidiaries (continued)

     (c)  6 3/4% Preferred Securities

          During  fiscal 1997,  a new  subsidiary  of the Company,  ICG Funding,
          completed a private placement of 6 3/4% Exchangeable Limited Liability
          Company Preferred Securities  Mandatorily Redeemable 2009 (the "6 3/4%
          Preferred  Securities")  for gross  proceeds of $132.25  million.  Net
          proceeds  from the  private  placement,  after  offering  costs,  were
          approximately $127.6 million.  Restricted cash at December 31, 1997 of
          $38.7  million  includes  the  proceeds  from the  offering  which are
          designated  for the payment of cash  dividends on the 6 3/4% Preferred
          Securities through November 15, 2000.

          The 6 3/4%  Preferred  Securities  consist of  2,645,000  exchangeable
          preferred securities of ICG Funding that bear a cumulative dividend at
          the  rate of 6 3/4% per  annum.  The  dividend  is paid  quarterly  in
          arrears  each  February  15, May 15,  August 15 and  November  15, and
          commenced  November 15, 1997.  The dividend is payable in cash through
          November  15,  2000 and  thereafter,  in cash or shares of ICG Common
          Stock, at the option of ICG Funding.  The 6 3/4% Preferred  Securities
          are  exchangeable,  at the option of the holder,  at any time prior to
          November  15,  2009 into  shares  of Common  Stock at a rate of 2.0812
          shares of Common Stock per preferred  security,  or $24.025 per share,
          subject to  adjustment.  ICG Funding may, at its option,  redeem the 6
          3/4%  Preferred  Securities at any time on or after November 18, 2000.
          Prior to that  time,  ICG  Funding  may  redeem  the 6 3/4%  Preferred
          Securities  if the  current  market  value of Common  Stock  equals or
          exceeds the exchange price, for at least 20 days of any 30-day trading
          period,  by 170% prior to November  16, 1998;  160% from  November 16,
          1998  through  November  15,  1999;  and 150% from  November  16, 1999
          through November 15, 2000. The 6 3/4% Preferred Securities are subject
          to mandatory redemption on November 15, 2009.

          On February 15, 1998, ICG Funding used the remaining proceeds from the
          private  placement  of the 6 3/4%  Preferred  Securities  to  purchase
          $112.4  million of ICG  Communications,  Inc.  Preferred  Stock  ("ICG
          Preferred  Stock")  which pays  dividends  each  February  15, May 15,
          August 15 and November 15 in additional  shares of ICG Preferred Stock
          through November 15, 2000.  Subsequent to November 15, 2000, dividends
          are payable in cash or shares of Common  Stock,  at the option of ICG.
          The ICG Preferred Stock is exchangeable, at the option of ICG

          Stock at an  exchange  rate based on the  exchange  rate of the 6 3/4%
          Preferred Securities.  The ICG Preferred Stock is subject to mandatory
          redemption on November 15, 2009.

          The accreted value of the 6 3/4%  Preferred  Securities is included in
          Company-obligated   mandatorily  redeemable  preferred  securities  of
          subsidiary  limited  liability  company  which  holds  solely  Company
          preferred  stock in the  accompanying  consolidated  balance  sheet at
          December 31, 1997.

     Included in  minority  interest in share of losses,  net of  accretion  and
     preferred   dividends   on  preferred   securities   of   subsidiaries   is
     approximately $1.3 million,  $27.0 million,  $5.8 million and $39.8 million
     for fiscal 1995 and 1996,  the three  months  ended  December  31, 1996 and
     fiscal 1997, respectively, associated with the accretion of issuance costs,
     discount and preferred  security dividend accruals for the 6 3/4% Preferred
     Securities,  the 14% Preferred  Stock,  the 14 1/4% Preferred Stock and the
     Redeemable  Preferred  Stock  (issued in  connection  with the 1995 Private
     Offering and redeemed in April 1996).  These costs are partially  offset by
     the minority interest share in losses of subsidiaries of approximately $0.6
     million,  $2.7  million,  $0.8 million and $2.0 million for fiscal 1995 and
     1996,   the  three  months  ended   December  31,  1996  and  fiscal  1997,

     (b)  Stock Options and Employee Stock Purchase Plan

          In fiscal years 1991,  1992 and 1993, the Company's Board of Directors
          approved  incentive  stock  option plans and  replenishments  to those
          plans  which  provide  for  the  granting  of  options  to  directors,
          officers,  employees  and  consultants  of  the  Company  to  purchase
          285,000, 724,400 and 1,692,700 shares, respectively,  of the Company's
          Common Stock,  with exercise  prices  between 80% and 100% of the fair
          value of the shares at the date of grant. A total of 1,849,600 options
          have been granted under these plans with exercise  prices ranging from
          approximately $2.92 to $14.03.  Compensation expense has been recorded
          for options  granted at an exercise  price below the fair market value
          of the  Company's  Common Stock at the date of grant,  pursuant to the
          provisions  of APB 25.  The  options  granted  under  these  plans are
          subject to  various  vesting  requirements  and expire in five and ten
          years from the date of grant.

          In fiscal years 1994,  1995 and 1996,  the three months ended December
          31, 1996 and fiscal 1997,  the Company's  Board of Directors  approved
          incentive and non-qualified  stock option plans and  replenishments to

          the  Company's  Common  Stock under the 1994 plan and an  aggregate of
          2,700,000 shares of the Company's Common Stock under the 1995 and 1996
          plans.  A total of 5,709,426  options  have been  granted  under these
          plans at original  exercise prices ranging from $7.94 to $27.06,  none
          of which  were less than 100% of the fair  market  value of the shares
          underlying  options  on  the  date  of  grant,  and  accordingly,   no
          compensation  expense was recorded for these options under APB 25. The
          options  granted  under  these  plans are  subject to various  vesting
          requirements and expire in five and ten years from the date of grant.

          In order to continue  to provide  non-cash  incentives  and retain key
          employees,  all employee  stock options  outstanding on April 16, 1997
          with  exercise  prices at or in excess of $15.875 were canceled by the
          Stock  Option  Committee  of the  Company's  Board  of  Directors  and
          regranted with an exercise price of $10.375,  the closing price of the
          Company's  Common  Stock on the  Nasdaq  National  Market on April 16,
          1997.  A total of  597,600  options,  with  original  exercise  prices
          ranging from $15.875 to $26.25, were canceled and regranted. There was
          no effect on the  Company's  consolidated  financial  statements  as a
          result of the cancellation and regranting of options.

          In October 1996,  the Company  established  an Employee Stock Purchase
          Plan  whereby  employees  can  elect to  designate  1% to 30% of their
          annual salary,  to be used to purchase shares of the Company's  Common
          Stock,  up to a limit of $25,000 in Common  Stock each year,  at a 15%
          discount to fair market value. Stock purchases will occur four times a
          year on February 1, May 1, August 1 and November 1, with the price per
          share  equaling the lower of 85% of the market price at the  beginning
          or end of the offering  period.  The Company is  authorized to issue a
          total of 1,000,000 shares of Common Stock to participants in the plan.
          During fiscal 1997,  the Company sold 109,213  shares of the Company's
          Common Stock to employees under this plan.

          The  Company  recorded  compensation  expense in  connection  with its
          stock-based employee and non-employee  director  compensation plans of
          $0.2 million and $0.1 million for fiscal 1995 and 1996,  respectively,
          pursuant  to  the  intrinsic   value  based  method  of  APB  25.  Had
          compensation  expense for the Company's plans been determined based on
          the fair market value of the options at the grant dates for awards

          The fair value of each option grant was estimated on the date of grant
          using  the  Black-Scholes  option-pricing  model  with  the  following
          weighted average  assumptions:  an expected option life of three years
          for directors,  officers and other executives, and two years for other
          employees,  for  all  periods;  expected  volatility  of 50%  for  all
          periods;  and risk-free interest rates ranging from 5.03% to 7.42% for
          fiscal 1995 and 1996 and the three months ended December 31, 1996, and
          risk-free  interest rates ranging from 5.61% to 6.74% for fiscal 1997.
          Risk-free  interest  rates,  as were currently  available on the grant
          date,  were assigned to each granted  option based on the  zero-coupon
          rate of U.S.  Treasury  bills to be held for the  same  period  as the
          assumed option life. Since the Company does not anticipate issuing any
          dividends on its Common  Stock,  the dividend  yield was assumed to be
          zero. The weighted average fair market value of options granted during
          fiscal 1995 and 1996,  the three  months  ended  December 31, 1996 and
          fiscal  1997 was  approximately  $4.11,  $5.28,  $9.42  and  $5.75 per
          option, respectively.

(13) Sale of Teleports

     In December  1995,  the Company  received  approximately  $21.1  million as
     partial  payment for the sale of four of its teleports and certain  related
     assets, and entered into a management  agreement with the purchaser whereby
     the purchaser assumed control of the teleport operations.  Upon approval of
     the  transaction  by the Federal  Communications  Commission  ("FCC"),  the
     Company  completed the sale in March 1996 and received an  additional  $0.4
     million due to certain  closing  adjustments,  for total  proceeds of $21.5
     million. The Company recognized a loss of approximately $1.1 million on the
     sale.  Revenue  associated  with these  operations was  approximately  $9.1
     million  and $2.5  million  for  fiscal  1995 and 1996,  respectively.  The
     Company  has  reported  results of  operations  from these  assets  through
     December 31, 1995.

     (a)  Network Construction

          In March 1996,  the Company and  Southern  California  Edison  Company
          ("SCE")  jointly  entered  into a 25-year  agreement  under  which the
          Company  will  lease  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 will be 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 $144.7 million at
          December 31, 1997.  The agreement has been  accounted for as a capital
          lease in the accompanying consolidated balance sheets.

          In May 1997, the Company  entered into a long-term  agreement with The
          Southern  Company   ("Southern")  that  will  permit  the  Company  to
          construct a 100-mile  fiber optic network in the Atlanta  metropolitan
          area.  The Company paid $5.5 million upon  execution of the  agreement
          and is responsible for  reimbursement to Southern for costs of network
          design,   construction,    installation,   maintenance   and   repair.
          Additionally, the Company is also required to pay Southern a quarterly
          fee based on specified  percentages of the Company's  revenue  derived
          from services provided over this network.  Network construction on the
          initial  43-mile build is expected to be completed by May of 1998. The
          Company   estimates   costs  to  complete  the  initial  build  to  be
          approximately  $5.2  million.  Other  than the  initial  $5.5  million
          payment, no costs have been incurred as of December 31, 1997.

          In January 1997, the Company  announced the formation of ChoiceCom,  a
          strategic  alliance  between the Company and CSW, which is expected to
          develop and market  telecommunications  services in certain  cities in
          Texas. CSW holds 100% of the partnership interest in ChoiceCom and the
          Company has an option to purchase a 50%  interest at any time prior to
          July 1, 2003.  Subsequent  to July 1,  1999,  if the  Company  has not
          exercised  its  option,  CSW  will  have the  right to sell,  at price
          pursuant to the terms of the limited partnership agreement, either 51%
          or 100% of the  partnership  interest  in  ChoiceCom  to the  Company.
          Additionally,  the  Company  has  committed  to loan $15.0  million to
          ChoiceCom  under two  promissory  notes,  of which  $10.0  million was
          advanced as of December  31, 1997 and the  remaining  $5.0 million was
          advanced during the first quarter of fiscal 1998.

          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 complete by
          December  1998.  The  Company  is  responsible   for  payment  on  the
          construction as segments of the network are completed and has incurred

          approximately  $8.0 million as of December 31, 1997,  with total costs
          anticipated  to be  approximately  $35.0  million.  Additionally,  the
          Company has  committed to purchase  $6.0  million in network  capacity
          from Qwest prior to the end of 1998.

     (b)  Company Headquarters

          During the three months ended December 31, 1996, the Company  acquired
          property for its new  headquarters  and commenced  construction  of an
          office building that will accommodate  most of the Company's  Colorado
          operations.   The  total  cost  of  the  project  is  expected  to  be
          approximately  $44.2 million, of which $29.4 million had been incurred
          as of December 31, 1997 and is included in  construction  in progress.
          In January 1998, the Company sold the substantially completed building
          to a third party and entered  into an  agreement  to lease back all of
          the office space under a 15-year  operating  lease which  includes two
          ten-year renewal terms.

     (c)  Other Commitments

          As part of the terms of the original purchase  agreement,  the Company
          was obligated to purchase,  at fair market value, all of the shares of
          Maritime   Telecommunications  Network,  Inc.  ("MTN"),  a  64%  owned
          subsidiary   of  the   Company,   that  were  owned  by  the  minority
          shareholders,   upon  demand  of  the  minority  shareholders,   if  a
          transaction  was not effected which converted the minority shares into
          publicly  traded  securities  or cash by January  3,  1998.  As of the
          current   date,   no  such  demand  has  been  made  by  the  minority
          shareholders.

          The Company has entered into  various  equipment  purchase  agreements
          with certain of its vendors.  Under these  agreements,  if the Company
          does not meet a minimum  purchase  level in any given year, the vendor
          may  discontinue  for that  year  certain  discounts,  allowances  and
          incentives  otherwise  provided  to  the  Company.  In  addition,  the
          agreements  may be terminated by either the Company or the vendor upon
          prior written notice.

          Additionally,  the Company has entered  into  certain  commitments  to
          purchase   capital   assets  with  an  aggregate   purchase  price  of
          approximately  $19.5 million at December 31, 1997.

     (d)  Leases

          The Company  leases  office space and equipment  under  non-cancelable
          operating leases.  Lease expense was approximately $2.8 million,  $5.1
          million,  $1.3 million and $11.8 million for fiscal 1995 and 1996, the
          three  months ended  December 31, 1996 and fiscal 1997,  respectively.
          Estimated  future minimum lease  payments for the years  subsequent to
          December 31, 1997 are (in thousands):

     (e)  Reciprocal Compensation

          The Company has  recorded  revenue of  approximately  $4.9 million for
          fiscal 1997 for reciprocal  compensation relating to the transport and
          termination  of local  traffic  to  Internet  service  providers  from
          customers of incumbent  local  exchange  carriers  pursuant to various
          interconnection  agreements.  These local  exchange  carriers 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 under state and federal laws and public  policies.  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
          rulings from 15 states and no  unfavorable  final rulings by any state
          public utilities  commission or the FCC that would indicate that calls
          placed by end users to Internet service providers would not qualify as
          local traffic subject to the payment of reciprocal compensation. While
          the Company  believes that all revenue  recorded  through December 31,
          1997 is collectible and that future  reciprocal  compensation  revenue
          will  be  realized,  there  can  be  no  assurance  that  such  future
          regulatory rulings will be favorable to the Company.

     (f)  Litigation

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

          The Company is a party to certain other litigation which has arisen in
          the ordinary  course of business.  In the opinion of  management,  the
          ultimate  resolution of these matters will not have a material adverse
          effect on the Company's financial condition,  results of operations or
          cash flows.

(15) Income Taxes

     The  components  of income tax  benefit  for fiscal 1996 are as follows (in
     thousands):

    Current income tax expense                 $    (198)
    Deferred income tax benefit                     5,329
                                            ---------------------
      Total                                    $    5,131
                                            =====================

     Current  income tax  expense for fiscal 1996  represents  state  income tax
     relating to operations of companies in states requiring separate entity tax
     returns.  Accordingly,  these entities'  taxable income cannot be offset by
     the Company's net operating  loss  carryforwards.  No income tax expense or
     benefit was  recorded in fiscal 1995,  the three months ended  December 31,
     1996 or fiscal 1997.

(15) Income Taxes (continued)

     During fiscal 1996, the deferred tax liability was adjusted for the effects
     of  certain  changes  in  estimated  lives of  property  and  equipment  as
     discussed in note 2 (j). As a result,  the Company recognized an income tax
     benefit of $5.3 million.

     Income tax benefit  differs from the amounts  computed by applying the U.S.
     federal income tax rate to loss before income taxes  primarily  because the
     Company  has not  recognized  the income tax  benefit of certain of its net
     operating  loss  carryforwards  and other  deferred  tax  assets due to the
     uncertainty of realization.

     The tax  effect of  temporary  differences  that  give rise to  significant
     portions  of the  deferred  tax  assets and  deferred  tax  liabilities  at
     December 31, 1996 and 1997 are as follows:

(15) Income Taxes (continued)

     As of December 31, 1997, the Company has net operating  losses  ("NOLs") of
     approximately  $353.0 million for U.S. tax purposes which expire in varying
     amounts  through  2012.  However,  due to the  provisions  of Section  382,
     Section 1502 and certain other provisions of the Internal Revenue Code (the
     "Code"), the utilization of these NOLs will be limited. The Company is also
     subject  to  certain  state  income  tax laws,  which  will also  limit the
     utilization of NOLs.

     A valuation allowance has been provided for the deferred tax asset relating
     to the Company's NOLs, as management cannot determine when the Company will
     generate future taxable income.

(16) Employee Benefit Plans

     The Company has established  salary  reduction  savings plans under Section
     401(k)  of  the  Code  which  the  Company  administers  for  participating
     employees. All full-time employees are covered under the plan after meeting
     minimum  service  and  age  requirements.  The  Company  makes  a  matching
     contribution of its Common Stock (up to

(16) Employee Benefit Plans (continued)

     a  maximum  of  6%  of  an  employee's  eligible  earnings)  which  totaled
     approximately  $0.5 million,  $1.2  million,  $0.5 million and $3.0 million
     during fiscal 1995 and 1996,  the three months ended  December 31, 1996 and
     fiscal 1997, respectively.

(17) Significant Customer

     During fiscal 1995,  the Company had revenue from a single  customer  which
     comprised 11% of total revenue and accounts  receivable  which comprised 8%
     of the total accounts  receivable balance at September 30, 1995. There were
     no customers  which  accounted  for greater than 10% of revenue or accounts
     receivable as of, or for the respective  periods ended  September 30, 1996,
     December 31, 1996 or 1997.

(18) Summarized Financial Information of ICG Holdings, Inc.

     As discussed  in note 10, the 11 5/8% Notes issued by Holdings  during 1997
     are  guaranteed  by ICG.  The 12 1/2%  Notes  and 13 1/2%  Notes  issued by
     Holdings during fiscal 1996 and 1995, respectively,  are also guaranteed by
     ICG and  Holdings-Canada.  The separate  complete  financial  statements of

1997 as contained  in the  Company's  Annual  Report on Form 10-K for the fiscal
year  ended   December  31,  1997.  In   connection   with  our  audits  of  the

FIRST PART:    TERM OF EMPLOYMENT, DUTIES AND SCOPE, COMPENSATION AND BENEFITS
               DURING EMPLOYMENT


Section 1:  Term of Employment

(a)  Basic Rule. The Corporation  agrees to continue the Employee's  employment,
     and the Employee agrees to remain in employment with the Corporation,  from
     June 1, 1997, until the earliest of:

     (1)  The date of the Employee's death; or

     (2)  The  date  when  the  Employee's  employment  terminates  pursuant  to
          Subsection (b), (c), (d) or (e) below.

(b)  Early  Termination  or  Resignation.  The  Corporation  may  terminate  the
     Employee's employment at any time and for any reason by giving the Employee
     written  notice.  The Employee may terminate the Employee's  employment for
     any reason by giving the  Corporation not less than 30 days' advance notice
     in writing.

(c)  Termination  for  Cause.  The  Corporation  may  terminate  the  Employee's
     employment  at any  time for  Cause  shown.  For all  purposes  under  this
     Agreement,  "Cause"  shall mean (1) a willful  failure by the  Employee  to
     substantially  perform the Employee's  duties under this  Agreement,  other
     than a failure resulting from the Employee's complete or partial incapacity
     due to physical or mental illness or  impairment,  (2) a willful act by the
     Employee that constitutes gross misconduct and that is materially injurious
     to the  Corporation,  (3) a willful  breach by the  Employee  of a material
     provision of this  Agreement  or (4) a material and willful  violation of a
     federal  or state  law or  regulation  applicable  to the  business  of the
     Corporation   that  is  materially  and   demonstrably   injurious  to  the
     Corporation. No act, or failure to act, by the Employee shall be considered
     "willful"  unless  committed  without  good faith and without a  reasonable
     belief that the act or omission was in the Corporation's best interest.

(d)  Termination  for  Disability.  The Corporation may terminate the Employee's
     employment for Disability by giving the Employee  written  notice.  For all
     purposes under this Agreement,  "Disability"  shall mean that the Employee,
     at the time the notice is given,  has been unable to perform the Employee's
     duties under this Agreement for a period of not less than three consecutive
     months as a result of the  Employee's  incapacity due to physical or mental
     illness.  In the  event  that  the  Employee  resumes  the  performance  of
     substantially  all of the Employee's duties under this Agreement before the
     termination  of  the  Employee's  employment  under  this  Section  becomes
     effective,  the notice of termination shall automatically be deemed to have
     been revoked.

(e)  Termination of Agreement.  This Agreement shall expire when all obligations
     of the parties  hereunder  have been  satisfied.  In  addition,  either the
     Corporation  or the Employee may terminate  this  Agreement for any reason,
     and without affecting the Employee's  status as an employee,  by giving the
     other party one year's  advance  notice in writing.  A termination  of this
     Agreement  pursuant to the  preceding  sentence  shall be effective for all
     purposes,  except  that such  termination  shall not affect the  payment or
     provision of  compensation or benefits under this Agreement on account of a
     termination  of  employment  occurring  prior  to the  termination  of this
     Agreement.

Section 2:  Duties and Scope of Employment

(a)  Position.  The  Corporation  agrees to employ the  Employee for the term of
     employment under this Agreement in the position of Chief Executive Officer.
     Employee shall be given such duties,  responsibilities  and  authorities as
     are appropriate to his position.

(b)  Obligations.  During  the term of  employment  under  this  Agreement,  the
     Employee shall devote the Employee's full business  efforts and time to the
     business and affairs of the  Corporation  as needed to carry out his duties
     and  responsibilities  hereunder subject to the overall  supervision of the
     Corporation's  Board of  Directors.  The  foregoing  shall not preclude the
     Employee  from  engaging in  appropriate  civic,  charitable  or  religious
     activities  or from  devoting  a  reasonable  amount  of  time  to  private
     investments  or from serving on the boards of directors of other  entities,
     as long as such  activities  and service do not  interfere or conflict with
     the Employee's responsibilities to the Corporation.

Section 3:  Base Compensation

During the term of employment  under this Agreement,  the Corporation  agrees to
pay the Employee as  compensation  for services a base salary at the annual rate
of $350,000, or at such higher rate as the Compensation/Option  Committee of the
Board of Directors may determine from time to time. Such salary shall be payable
in accordance with the standard payroll procedures of the Corporation.  Once the
Corporation's  Compensation/Option  Committee  of the  Board  of  Directors  has
increased such salary,  it thereafter shall not be reduced;  provided,  however,
that if a Change  in  Control  has not  occurred,  such  salary  (including  any
increases) may be reduced by the Corporation if (1) the Employee  commits an act
or omission that meets the  definition of Cause,  as defined in Section 1(c), or
(2) the Employee and all other  executive  officers of the  Corporation  who are
parties to  written  employment  agreements  containing  substantially  the same
provisions as this  Agreement  have their  salaries  (including  any  increases)
reduced  by the same  percentage  amount  for the same time  period.  The annual
compensation  specified in this Section 3,  together  with any increases in such
compensation  that the  Compensation/Option  Committee of the Board of Directors
may grant from time to time, and together with any reductions made in accordance
with this Section 3, is referred to in this Agreement as "Base Compensation."

Section 4:  Employee Benefits

In General.  During the term of employment  under this  Agreement,  the Employee
shall be eligible to  participate  in the employee  benefit  plans and executive
compensation   programs  maintained  by  the  Corporation,   including  (without
limitation) savings or profit-sharing  plans, deferred compensation plans, stock
option,  incentive or other bonus plans, life, disability,  health, accident and
other insurance programs, paid vacations, and similar plans or programs, subject
in each case to the  generally  applicable  terms and  conditions of the plan or
program in question  and to the  discretion  and  determinations  of any person,
committee or entity  administering such plan or program.  In addition,  Employee
shall  be  eligible  for a car  allowance  of  $600  per  month  and a  cellular
telephone.

Section 5:  Business Expenses and Travel

During  the term of  employment  under this  Agreement,  the  Employee  shall be
authorized to incur  necessary and reasonable  travel,  entertainment  and other
business  expenses in  connection  with the  Employee's  duties  hereunder.  The
Corporation  shall reimburse the Employee for such expenses upon presentation of
an itemized account and appropriate supporting documentation,  all in accordance
with generally applicable policies.

SECOND PART:   COMPENSATION AND BENEFITS IN CASE OF ACTUAL OR CONSTRUCTIVE 
               TERMINATION NOT OCCURRING WITHIN SIX MONTHS AFTER A CHANGE 
               IN CONTROL

Section 6:  Terminations Not Relating to a Change in Control

This Second Part of the Agreement, consisting of Sections 6 through 8, describes
the  benefits  and  compensation,  if any,  payable  in case of  termination  of
employment  that does not occur  within six months after a Change in Control (as
defined in Section 12). The Third Part of the Agreement,  consisting of Sections
9 through 12, describes  benefits and  compensation,  if any, payable in case of
termination  occurring within six months after a Change in Control.  If benefits
and  compensation  are payable  under this  Second  Part,  then no benefits  and
compensation are payable under the Third Part.

Section 7:  Involuntary Actual Or Constructive Termination Without Cause 
            or Disability

In the event that, during the term of this Agreement,  the Employee's employment
terminates in a Qualifying  Termination,  as defined in Subsection (a), and such
termination  does not occur within six months  after a Change in Control,  then,
after  executing the release of claims  described in Section 7(d),  the Employee
shall be entitled to receive the payments and benefits  described in Subsections
(b) and (c).

(a)  Qualifying Termination. A Qualifying Termination occurs if:

     (1)  The  Corporation  terminates the Employee's  employment for any reason
          other than Cause or Disability; or

     (2)  The  Employee  separates  from  employment  with  the  Corporation  in
          response  to a  "Constructive  Termination,"  which  means a  material
          reduction  in salary or  benefits  (subject  to Section 3), a material
          change in responsibilities,  or a requirement to relocate,  except for
          office  relocations  that would not  increase the  Employee's  one-way
          commute distance by more than 20 miles.


(b)  Severance (1x payment). The Corporation shall pay to the Employee following
     the date of the employment  termination  and over the succeeding 12 months,
     in accordance  with  standard  payroll  procedures,  an amount equal to the
     following:

     (1)  One times the Employee's  Base  Compensation  in effect on the date of
          the employment termination; plus

     (2)  100% of the Employee's  annual  incentive  bonus earned on a quarterly
          basis as of the date of the  termination,  assuming  the  Employee was
          employed  on the  last day of the  quarter  in  which  termination  of
          employment occurred.

          Any  other  provision  of  this  Agreement  or  of  the  Corporation's
          Incentive Bonus Plan  notwithstanding,  after the amount  described in
          this Subsection (b) has been paid to the Employee,  the Employee shall
          have no further interest in such Plan.

(c)  Twelve  Months of Life  Insurance  and Health Plan  Coverage.  The coverage
     described  in this  Subsection  (c) shall be provided  for a  "Continuation
     Period" beginning on the date when the employment  termination is effective
     and ending on the earlier of (1) the 12-month  anniversary of the date when
     the  employment  termination is effective or (2) the date of the Employee's
     death. During the Continuation Period, the Employee (and, where applicable,
     the Employee's  dependents) shall be entitled to continue  participation in
     the  group  term  life  insurance  plan  and in the  health  care  plan for
     employees  maintained by the  Corporation  as if the Employee were still an
     employee of the  Corporation.  The coverage  provided under this Subsection
     (c)  shall  run   concurrently   with  and  shall  be  offset  against  any
     continuation  coverage  under Part 6 of Title I of the Employee  Retirement
     Income Security Act of 1974, as amended.  Where applicable,  the Employee's
     compensation  for purposes of such plans shall be deemed to be equal to the
     Employee's compensation (as defined in such plans) in effect on the date of
     the employment  termination.  To the extent that the  Corporation  finds it
     undesirable to cover the Employee under the group life insurance and health
     plans of the  Corporation,  the Corporation  shall provide the Employee (at
     its own expense) with the same level of coverage under individual policies.

(d)  Release of Claims.  As a  condition  to the  receipt  of the  payments  and
     benefits  described in this  Section 7, the  Employee  shall be required to
     execute a release of all claims 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,  but  excluding  claims  for
     indemnification  from the Corporation under any  indemnification  agreement
     with the  Corporation,  its  certificate  of  incorporation  and by-laws or
     applicable law or claims for directors and officers' insurance coverage.

(e)  Conditions  to Receipt of  Payments  and  Benefits.  In view of  Employee's
     position and his access to Confidential Information,  as a condition to the
     receipt of payments and benefits  described in this Section 7, the Employee
     shall  not,  without  the  Corporation's   written  consent,   directly  or
     indirectly,  alone or as a  partner,  joint  venturer,  officer,  director,
     employee,  consultant,  agent or  stockholder  (other  than a less  than 5%
     stockholder of a publicly  traded company) (i) engage in any activity which
     is in  competition  with the  business,  the  products  or  services of the
     Corporation (a list of competitors and  competitive  products and services,
     which  may  be  updated,  is  attached  hereto),  (ii)  solicit  any of the
     Corporation's  employees,  consultants or customers,  (iii) hire any of the
     Corporation's  employees or consultants  in an unlawful  manner or actively
     encourage  employees  or  consultants  to leave  the  Corporation,  or (iv)
     otherwise breach his Confidential Information obligations.

(f)  No Mitigation. The Employee shall not be required to mitigate the amount of
     any payment or benefit  contemplated  by this Section 7, nor shall any such
     payment or benefit be reduced by any earnings or benefits that the Employee
     may receive from any other source.

Section 8: Other Terminations Under This Part

If termination of employment,  actual or constructive,  occurs at a time that is
not within six months  after a Change in  Control,  and the  termination  is not
described in Section 7, then the Employee is entitled only to the  compensation,
benefits and  reimbursements  payable  under the terms of Sections 3, 4 and 5 of
this Agreement for the period  preceding the effective  date of the  termination
including any  disability or death  benefits to which Employee (or his estate or
beneficiary(s))  may be entitled as a result of termination of his employment on
account of Disability or death.  The payments under this  Agreement  shall fully
discharge  all   responsibilities  of  the  Corporation  to  the  Employee  upon
termination  of the  Employee's  employment.  This  Section 8  applies,  without
limitation,  to any termination of employment  initiated by the Employee (except
an  Employee-initiated  termination  that is described in Paragraph 2 of Section
7(a)),  termination of employment  caused by the Employee's death or Disability,
termination of the Employee for Cause,  and any  constructive  termination  (not
described in Section 7).

THIRD PART:  COMPENSATION AND BENEFITS IN CASE OF ACTUAL OR CONSTRUCTIVE 
             TERMINATION OCCURRING WITHIN SIX MONTHS AFTER A CHANGE IN CONTROL

Section 9:  Terminations Relating to a Change in Control

This Third Part of the Agreement, consisting of Sections 9 through 12, describes
the  benefits  and  compensation,  if any,  payable  in case of  termination  of
employment  that occurs  within six months after a Change in Control (as defined
in Section  12).  The Second  Part of the  Agreement,  consisting  of Sections 6
through 8,  describes  benefits  and  compensation,  if any,  payable in case of
termination that does not occur within six months after a Change in Control.  If
benefits and  compensation  are payable under this Third Part,  then no benefits
and compensation are payable under the Second Part.

Section 10: Involuntary Actual or Constructive Termination Without Cause

In the event that, during the term of this Agreement and within six months after
a Change in  Control,  the  Employee's  employment  terminates  in a  Qualifying
Termination, the Employee shall be entitled to receive the payments and benefits
described in Subsections (a), (b) and (c).

(a)  Severance (2x payment). The Corporation shall pay to the Employee in a lump
     sum, not less than 31 days nor more than 60 days  following the date of the
     employment termination, an amount equal to the following:

     (1)  Two times the Employee's  Base  Compensation  in effect on the date of
          the employment termination; plus

     (2)  200% of the greater of his prior year's  incentive bonus or his annual
          incentive  bonus  earned  on a  quarterly  basis as of the date of the
          termination, assuming the Employee was employed on the last day of the
          quarter in which termination of employment occurred.

          Any  other  provision  of  this  Agreement  or  of  the  Corporation's
          Incentive Bonus Plan  notwithstanding,  after the amount  described in
          this Subsection (a) has been paid to the Employee,  the Employee shall
          have no further interest in such Plan.

(b)  Two  Years  of Life  Insurance  and  Health  Plan  Coverage.  The  coverage
     described  in this  Subsection  (c) shall be provided  for a  "Continuation
     Period" beginning on the date when the employment  termination is effective
     and ending on the  earlier of (1) the second  anniversary  of the date when
     the  employment  termination is effective or (2) the date of the Employee's
     death. During the Continuation Period, the Employee (and, where applicable,
     the Employee's  dependents) shall be entitled to continue  participation in
     the  group  term  life  insurance  plan  and in the  health  care  plan for
     employees  maintained by the  Corporation  as if the Employee were still an
     employee of the  Corporation.  The coverage  provided under this Subsection
     (c)  shall  run   concurrently   with  and  shall  be  offset  against  any
     continuation  coverage  under Part 6 of Title I of the Employee  Retirement
     Income Security Act of 1974, as amended.  Where applicable,  the Employee's
     compensation  for purposes of such plans shall be deemed to be equal to the
     Employee's compensation (as defined in such plans) in effect on the date of
     the employment  termination.  To the extent that the  Corporation  finds it
     undesirable to cover the Employee under the group life insurance and health
     plans of the  Corporation,  the Corporation  shall provide the Employee (at
     its own expense) with the same level of coverage under individual policies.

(c)  Incentive  Programs.  All options granted by the Corporation  shall vest an
     additional  50% (or the remaining  unvested  options if less than 50%) upon
     the  effective  date of the Change in Control  and any  remaining  unvested
     options  shall  fully vest upon a  Qualifying  Termination  within 6 months
     after the Change in Control.

(d)  No Mitigation. The Employee shall not be required to mitigate the amount of
     any payment or benefit  contemplated by this Section 10, nor shall any such
     payment or benefit be reduced by any earnings or benefits that the Employee
     may receive from any other source.

Section 11:       Other Terminations Under This Part

If termination of employment,  actual or constructive,  occurs at a time that is
within  six  months  after a  Change  in  Control,  and the  termination  is not
described in Section 10, then the Employee is entitled only to the compensation,
benefits and  reimbursements  payable  under the terms of Sections 3, 4 and 5 of
this Agreement for the period  preceding the effective  date of the  termination
including any  disability or death  benefits to which Employee (or his estate or
beneficiary(s))  may be entitled as a result of termination of his employment on
account of Disability or death.  The payments under this  Agreement  shall fully
discharge  all   responsibilities  of  the  Corporation  to  the  Employee  upon
termination  of the  Employee's  employment.  This  Section 11 applies,  without
limitation,  to any termination of employment  initiated by the Employee (except
an Employee-initiated  termination that is described in Paragraph (2) of Section
7(a))  or a  termination  of  employment  caused  by  Disability,  Cause  or the
Employee's death.

Section 12:       Definition of Change in Control

For all purposes under this Agreement,  "Change in Control" shall mean a "Change
in Control" of the Corporation,  as defined in the NetCom On-Line Communications
Services, Inc. 1993 Stock Option Plan as in effect on the date this Agreement is
executed.

FOURTH PART:      PARACHUTE PAYMENTS


Section 13:       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
Corporation,  any Person who  acquires  ownership  or  effective  control of the
Corporation,  or  ownership  of a  substantial  portion  of  the  assets  of the
Corporation  (within the meaning of section 260G of the Code and the regulations
thereunder)  or any  affiliate  of such Person (the "Total  Payments")  would be
subject to the excise tax imposed by section 4999 of the Code or any interest or
penalties  with respect to such excise tax (such excise tax,  together  with any
such 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 Payments.

Section 14:       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 14, 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 14,
shall be made by an  independent  accounting  firm selected by the Employee from
amount the largest six  accounting  firms in the United States (the  "Accounting
Firm"). The Accounting Firm shall provide to the Corporation 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 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 days after the  Determination is delivered to
the Corporation or the Employee.  Any determination by the Accounting Firm shall
be binding upon the Corporation 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  Corporation and members of the
Corporation  should have been made  ("Underpayment"),  or that Gross-Up Payments
will have been made by the  Corporation  and  members  of the  Corporation  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 Corporation 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  Corporation,  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 Corporation, and otherwise
reasonably cooperate with the Corporation to correct such Overpayment; provided,
however,  that (1) Employee shall not in any event be obligated to return to the
Corporation 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  13,  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
Corporation an amount that is less than the Overpayment.

FIFTH PART:       TRADE SECRETS, SUCCESSORS, MISCELLANEOUS PROVISIONS, 
                  SIGNATURE PAGE


Section 15:  Confidential Information

(a)  Acknowledgement.  The  Corporation  and the Employee  acknowledge  that the
     services to be performed by the Employee  under this  Agreement  are unique
     and extraordinary and that, as a result of the Employee's  employment,  the
     Employee  will be in a  relationship  of  confidence  and  trust  with  the
     Corporation and will come into possession of "Confidential Information" (1)
     owned  or  controlled  by the  Corporation,  (2) in the  possession  of the
     Corporation  and belonging to third parties or (3)  conceived,  originated,
     discovered  or developed,  in whole or in part,  by the  Employee.  As used
     herein   "Confidential   Information   includes  trade  secrets  and  other
     confidential  or proprietary  business,  technical,  personnel or financial
     information,  whether  or not the  Employee's  work  product,  in  written,
     graphic,  oral or other  tangible or  intangible  forms,  including but not
     limited to  specifications,  samples,  records,  data,  computer  programs,
     drawings,  diagrams,  models,  customer  names,  ID's or e-mail  addresses,
     business or marketing plans,  studies,  analyses,  projections and reports,
     communications  by or to attorneys  (including  attorney-client  privileged
     communications),  memos and other materials  prepared by attorneys or under
     their direction (including attorney work product), and software systems and
     processes.  Any  information  that is not readily  available  to the public
     shall be considered to be a trade secret and  confidential and proprietary,
     even if it is not  specifically  marked  as such,  unless  the  Corporation
     advises the Employee otherwise in writing.

(b)  Nondisclosure.  The Employee agrees that the Employee will not, without the
     prior written  consent of the  Corporation,  directly or indirectly  use or
     disclose  Confidential  Information  to any  person,  during  or after  the
     Employee's employment, except as may be necessary in the ordinary course of
     performing the Employee's  duties under this  Agreement.  The Employee will
     keep the Confidential  Information in strictest  confidence and trust. This
     Section 15 shall apply indefinitely, both during and after the term of this
     Agreement.

(c)  Surrender Upon  Termination.  The Employee  agrees that in the event of the
     termination of the Employee's  employment for any reason, the Employee will
     immediately  deliver  to the  Corporation  all  property  belonging  to the
     Corporation, including all documents and materials of any nature pertaining
     to the  Employee's  work with the  Corporation,  and will not take with the
     Employee any documents or materials of any description, or any reproduction
     thereof of any  description,  containing or pertaining to any  Confidential
     Information.  It is understood that the Employee is free to use information
     that  is in the  public  domain  (not  as a  result  of a  breach  of  this
     Agreement).

Section 16:       Successors

(a)  Corporation's  Successors.  The  Corporation  shall  require any  successor
     (whether  direct or  indirect  and  whether  by  purchase,  lease,  merger,
     consolidation, liquidation or otherwise) to all or substantially all of the
     Corporation's business and/or assets, by an agreement in substance and form
     satisfactory  to the  Employee,  to  assume  this  Agreement  and to  agree
     expressly  to perform  this  Agreement  in the same  manner and to the same
     extent as the Corporation would be required to perform it in the absence of
     a succession.  The Corporation's  failure to obtain such agreement prior to
     the  effectiveness  of a succession shall be a breach of this Agreement and
     shall entitle the Employee to all of the compensation and benefits to which
     the Employee  would have been  entitled  hereunder if the  Corporation  had
     involuntarily   terminated  the  Employee's  employment  without  Cause  or
     Disability,  on the date when such succession  becomes  effective.  For all
     purposes under this  Agreement,  the term  "Corporation"  shall include any
     successor to the  Corporation's  business  and/or  assets that executes and
     delivers the assumption  agreement described in this Subsection (a) or that
     becomes bound by this Agreement by operation of law.

(b)  Employee's  Successors.  This  Agreement  and all  rights  of the  Employee
     hereunder  shall  inure to the  benefit  of,  and be  enforceable  by,  the
     Employee's personal or legal  representatives,  executors,  administrators,
     successors, heirs, distributees, devisees and legatees.

Section 17:  Miscellaneous Provisions

(a)  Waiver.  No  provision  of this  Agreement  shall be  modified,  waived  or
     discharged  unless the  modification,  waiver or  discharge is agreed to in
     writing  and signed by the  Employee  and by an  authorized  officer of the
     Corporation  (other than the  Employee).  No waiver by either  party of any
     breach of, or of  compliance  with,  any  condition  or  provision  of this
     Agreement  by the other  party  shall be  considered  a waiver of any other
     condition  or  provision  or of the same  condition or provision at another
     time.

(b)  Whole Agreement. No agreements,  representations or understandings (whether
     oral or written and whether  express or implied) that are not expressly set
     forth in this Agreement, or any existing indemnification  agreement for the
     benefit of the  Employee,  have been made or entered  into by either  party
     with respect to the subject matter hereof. In addition, the Employee hereby
     acknowledges and agrees that this Agreement  supersedes in its entirety any
     employment  agreement  between the Employee and the  Corporation  in effect
     immediately  prior  to the  effective  date  of this  Agreement.  As of the
     effective date of this Agreement, such employment agreement shall terminate
     without any further  obligation by either party  thereto,  and the Employee
     hereby relinquishes any further rights that the Employee may have had under
     such prior employment agreement.

(c)  Notice. Notices and all other communications contemplated by this Agreement
     shall be in  writing  and shall be deemed  to have  been  duly  given  when
     personally  delivered or when mailed by U.S.  registered or certified mail,
     return receipt requested and postage prepaid.  In the case of the Employee,
     mailed  notices shall be addressed to the Employee at the home address that
     the Employee most recently  communicated to the Corporation in writing.  In
     the case of the  Corporation,  mailed  notices  shall be  addressed  to its
     corporate headquarters,  and all notices shall be directed to the attention
     of its Chief Operating Officer.

(d)  No Setoff. There shall be no right of setoff or counterclaim,  with respect
     to any claim,  debt or obligation,  against  payments to the Employee under
     this Agreement.

(e)  Choice of Law. The validity,  interpretation,  construction and performance
     of this Agreement shall be governed by the laws of the State of California,
     irrespective of California's choice-of-law principles.

(f)  Severability.  The  invalidity  or  unenforceability  of any  provision  or
     provisions   of  this   Agreement   shall  not  affect  the   validity   or
     enforceability  of any other provision  hereof,  which shall remain in full
     force and effect.

(g)  Arbitration.  Except  as  otherwise  provided  in  Section  14  and  in the
     enforcement  of Section 15, 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.

(h)  No Assignment of Benefits. The rights of any person to payments or benefits
     under this  Agreement  shall not be made  subject to option or  assignment,
     either by  voluntary  or  involuntary  assignment  or by  operation of law,
     including (without limitation) bankruptcy, garnishment, attachment or other
     creditor's  process,  and any action in  violation of this  Subsection  (i)
     shall be void.

(i)  Employment  at  Will;  Limitation  of  Remedies.  The  Corporation  and the
     Employee acknowledge that the Employee's  employment is at will, as defined
     under  applicable  law. If the  Employee's  employment  terminates  for any
     reason,  the  Employee  shall not be  entitled to any  payments,  benefits,
     damages, awards or compensation other than as provided by this Agreement.

(j)  Employment  Taxes.  All payments made pursuant to this  Agreement  shall be
     subject to withholding of applicable taxes.

(k)  Benefit Coverage  Non-Additive.  In the event that the Employee is entitled
     to life  insurance and health plan  coverage  under more than one provision
     hereunder,  only one  provision  shall  apply,  and  neither the periods of
     coverage nor the amounts of benefits shall be additive.


IN WITNESS WHEREOF, each of the parties has executed this Agreement, in the case
of the Corporation by its duly authorized  officer, as of the day and year first
above  written.  Employee has consulted (or has had the  opportunity to consult)
with his own counsel  (who is other than the  Corporation's  counsel,  Pillsbury
Madison & Sutro, LLP) prior to execution of this Agreement.

purchase  from  Seller,  upon and  subject to the terms and  conditions  in this
Agreement, all of the following property (collectively the "Property"):

     (a) The real property in the City of Englewood,  County of Arapahoe,  State
of Colorado, commonly known as 161 Inverness Drive West, Englewood, Colorado, as
described  in  commitment  no.  ABS568808-2  dated  as of  July  17,  1997  (the

                                    ARTICLE 2

                                 Purchase Price

     2.1 Amount and Payment.  The total purchase price for the Property shall be
forty-four  million two hundred thousand dollars  ($44,200,000).  At the Closing

PROPERTY IS NOT COMPLETED,  THEN THIS AGREEMENT  SHALL TERMINATE AND BUYER SHALL
PAY TWO  MILLION  FIVE  HUNDRED  THOUSAND  DOLLARS  ($2,500,000)  TO SELLER UPON
TERMINATION  OF THIS  AGREEMENT  WHICH  AMOUNT  SHALL BE  RETAINED  BY SELLER AS

BUYER  AGREE  THAT,  UNDER  THE  CIRCUMSTANCES  EXISTING  AS OF THE DATE OF THIS
AGREEMENT,  ACTUAL  DAMAGES MAY BE DIFFICULT  TO  ASCERTAIN  AND THAT THE AMOUNT
SPECIFIED ABOVE IS A REASONABLE ESTIMATE OF THE DAMAGES THAT WILL BE INCURRED BY
SELLER IF BUYER MATERIALLY  DEFAULTS UNDER OR MATERIALLY BREACHES THIS AGREEMENT
AND FAILS TO PURCHASE THE PROPERTY.

          (b) if the  Closing  shall not have  occurred on or prior to March 15,

If Buyer delivers such notice of  termination,  this Agreement  shall  terminate
immediately  and neither party shall have any further  obligations  to the other
hereunder,  except as provided in the  following  sentence.  If (1) Seller shall
have ceased,  for a period of thirty (30) days or more, to diligently  prosecute
the  completion of the Project or shall have stated its intention to discontinue
work  on  the  Project,   and  (2)  such  cessation  or  discontinuance  is  not
necessitated by Force Majeure (as defined below),  and (3) Buyer terminates this
Agreement,  then Seller shall pay to Buyer two hundred  fifty  thousand  dollars
($250,000) as liquidated  damages for Seller's  failure to complete the Project.
SELLER AND BUYER AGREE THAT,  IF THE EVENTS  LISTED IN CLAUSES 1, 2 AND 3 OF THE
PRECEDING  SENTENCE OCCUR, THEN IT SHALL CONSTITUTE A MATERIAL DEFAULT BY SELLER
UNDER THIS AGREEMENT AND THAT, UNDER THE  CIRCUMSTANCES  EXISTING AS OF THE DATE
OF THIS  AGREEMENT,  ACTUAL  DAMAGES MAY BE DIFFICULT TO ASCERTAIN  AND THAT THE
AMOUNT  SPECIFIED  ABOVE IS A  REASONABLE  ESTIMATE OF THE DAMAGES  THAT WILL BE
INCURRED  BY BUYER  IF  SELLER  MATERIALLY  DEFAULTS  UNDER  THIS  AGREEMENT  AS
DESCRIBED  ABOVE.  Nothing in this  section 3.2 shall  impair  Buyer's  right to
specifically  enforce  Seller's  obligations  under  this  Agreement  in lieu of
seeking the remedy set forth in this section 3.2.

         Seller's initials:  JDG           Buyer's initials:  GPL

As used herein, the term "Force Majeure" shall mean fire,  earthquake,  tornado,
flood,  other  acts  of  God,  strike,  lockout,  acts of  public  enemy,  riot,
insurrection,  or  governmental  regulation  of the  sale or  transportation  of
materials, supplies or labor.

     3.3  Buyer's  Right to  Accelerate  Closing.  Buyer shall have the right to
accelerate  the Closing  Date,  by notice to Seller,  to a date in December 1997
specified  in such  notice  (provided  that such date shall be not less than ten
(10) business days after the date such notice is delivered) notwithstanding that
the condition set forth in section 8.2(d) shall not have been satisfied.  In the
event that on such  specified  date (the  "Accelerated  Closing Date") any other
condition  set forth in section 8.2 shall not have been  satisfied,  Buyer shall
have the right to postpone the Closing until such condition has been  satisfied.
On the  Accelerated  Closing Date,  the Closing  shall occur in accordance  with
Articles 8 and 9 of this Agreement,  except that a portion of the purchase price
equal to one  hundred  thirty  percent  (130%) of the  Unpaid  Project  Cost (as
defined  below)  shall be held in escrow on such  terms as Buyer may  reasonably
require and shall be paid to Seller  after the  Closing as  follows:  Buyer will
instruct  the escrow  holder to disburse to Seller,  from time to time,  amounts
equal to amounts paid by Seller for completed  portions of the  Unfinished  Work
(as defined  below),  as evidenced by paid  invoices  describing  the  completed
portions;  the  balance of such  funds  shall be paid upon  satisfaction  of the
condition  set forth in  section  8.2(d),  but  subject  to the terms of section
7.5(j). The term "Unpaid Project Costs" means the cost, as reasonably  estimated
by the  Architect  (as  defined in section  7.5(h)) and  reasonably  approved by
Buyer, of the work remaining to be completed as of the Closing Date ("Unfinished
Work") in order to achieve  substantial  completion of the Project. In the event
the actual  amount of the Unpaid  Project  Costs  exceeds  the amount so held in
escrow, Seller shall pay such excess costs.

notice to Seller,  to terminate this Agreement.  In addition,  if Buyer fails to
obtain the Board  Approval (as defined in section  8.2(a)) by the Board Approval
Date, than Buyer shall have the right, by giving notice to Seller,  to terminate
this  Agreement.  If Buyer  exercises the right to terminate  this  Agreement in
accordance  with this section 5.4, this Agreement shall terminate as of the date
such termination  notice is given by Buyer. If Buyer does not exercise the right
to terminate  this  Agreement  in  accordance  with this section 5.4,  then this
Agreement  shall  continue  in full force and  effect,  and Buyer  shall have no
further  right  to  terminate  this  Agreement  pursuant  to this  section  5.4.
Notwithstanding the foregoing or any contrary  provisions of this Agreement,  if
Buyer fails to deliver to Seller  notice of the Board  Approval on or before the
Board Approval Date, then Seller may deliver to Buyer notice of Buyer's failure,

                         Representations and Warranties

     6.1 Seller.  The  representations  and warranties of Seller in this section
6.1 and in Seller's  Closing  Certificate  (as defined in section  7.1(c)) are a
material  inducement  for Buyer to enter into this  Agreement.  Buyer  would not
purchase the Property from Seller without such representations and warranties of
Seller. All  representations and warranties of Seller shall survive the Closing.
Seller  represents  and  warrants to Buyer as of the date of this  Agreement  as
follows:

     (a)  Seller  is a  corporation  existing  under  the  laws of the  State of
Colorado.  Seller has full power and authority to enter into this  Agreement and
the Lease and to perform this Agreement and the Lease.  The execution,  delivery
and  performance  of this  Agreement  and the Lease by Seller have been duly and
validly  authorized  by all  necessary  action  on the  part of  Seller  and all
required consents and approvals have been duly obtained.  This Agreement is, and
upon  execution  the Lease will be, a legal,  valid and  binding  obligation  of
Seller,  enforceable against Seller in accordance with its terms, subject to the
effect  of  applicable  bankruptcy,  insolvency,  reorganization,   arrangement,
moratorium  or other similar laws  affecting the rights of creditors  generally.
Neither the  execution  and  delivery of this  Agreement  or the Lease,  nor the
consummation of the transactions  contemplated hereby or thereby,  will conflict
with,  or (with or  without  notice  or lapse  of  time,  or both)  result  in a
termination, breach, impairment or violation of, or give rise to a default under
(i) any  provision of Seller's  articles of  incorporation  or bylaws,  (ii) any
material instrument or contract to which Seller is a party or by which Seller is
bound, or (iii) any federal,  state,  local or foreign judgment,  writ,  decree,
order,  statute,  rule or regulation  applicable to Seller,  the Property or any
other property of Seller.

     (b)  There are no  presently  effective  leases,  lease  amendments,  lease
guaranties,   work  letter  agreements,   improvement   agreements,   subleases,
assignments,  licenses,  concessions  or other  agreements  with  respect to the
leasing, use or occupancy of the Real Property or any part thereof. There are no
persons leasing, using or occupying the Real Property or any part thereof except
Seller.  All of the Personal Property is described in Exhibit B attached hereto,
which is an accurate and complete list of all tangible and  intangible  personal
property owned by Seller  relating to the ownership,  construction,  management,
operation,  maintenance  or repair  of the Real  Property.  All of the  tangible
Personal  Property is located at the Real  Property.  All of the  Contracts  are
described in Exhibit C attached  hereto,  which is an accurate and complete list
of all presently effective contracts,  agreements,  warranties and guaranties to
which  Seller  is a party or by  which  Seller  or the  Property  may be  bound,
relating  to  the  advertising,  promotion,  design,  construction,   ownership,
management,  operation,  maintenance or repair of the Real  Property,  and which
could  continue to be in effect after the Closing  Date.  All of the Permits are
described in Exhibit D attached  hereto,  which is an accurate and complete list
of all presently  effective  building  permits,  certificates of occupancy,  and
other necessary  certificates,  permits,  licenses and approvals relating to the
design,  construction,   ownership,   occupancy,  use,  management,   operation,
maintenance  or  repair  of the Real  Property.  Seller  has  good  title to the
Personal Property,  the Contracts and the Permits,  free and clear of all liens,
encumbrances,  security  interests  and  adverse  claims  of any kind or  nature
whatsoever.  All of the copies of the documents  delivered to Buyer  pursuant to
section 5.1 are accurate and complete  copies of all  originals of the documents
described in section 5.1.

     (c) Except for the fee payable by Seller to the Broker in  connection  with
the transactions  described in this Agreement,  there are no leasing commissions
or other commissions,  fees or compensation  presently owed or which will become
due and payable  with respect to the Lease or which could become due and payable
in the future upon the exercise of any right or option contained in the Lease.

     (d) The Real  Property and every part thereof and (as of the Closing  Date)
the use and  occupancy  of the Real  Property  are in full  compliance  with all
applicable building, earthquake, zoning, land use, environmental, antipollution,
health, fire, safety, access and accommodations for the physically  handicapped,
subdivision,  energy and resource conservation or similar laws, statutes, rules,
regulations  and  ordinances  and all  covenants,  conditions  and  restrictions
applicable  to the Real  Property.  Seller has  received no notice,  citation or
other claim alleging any violation of any such law, statute,  rule,  regulation,
ordinance,  covenant,  condition or restriction.  The Real Property (as shown in
the Design Documents)  includes  sufficient parking spaces to satisfy all zoning
and private land use requirements. The Real Property has direct access to one or
more public streets.  The Permits have been duly and validly issued, are in full
force  and  effect,  and  are all of the  certificates,  permits,  licenses  and
approvals  that are  required  by law to own,  operate,  use and occupy the Real
Property  as it is  presently,  or  is  presently  contemplated  to  be,  owned,
operated,  used  and  occupied.  Seller  has  fully  performed,   satisfied  and
discharged all of the obligations,  requirements  and conditions  imposed on the
Real Property by the Permits.

     (e) Except as permitted by  applicable  Environmental  Laws or disclosed in
the  Environmental  Reports,  to the actual  knowledge  of Seller,  no Hazardous
Substances  are  present  in, on or under the Real  Property  or any nearby real
property  which  could  migrate  to the Real  Property,  and there is no present
Release or threatened  Release of any Hazardous  Substances  in, on or under the
Real Property.  Seller has never used the Real Property or any part thereof, and
Seller  has never  permitted  any  person to use the Real  Property  or any part
thereof, for the production,  processing,  manufacture,  generation,  treatment,
handling, storage or disposal of Hazardous Substances, except in compliance with
applicable  Environmental  Laws.  Except for one (1) 20,000  gallon  underground
water tank, no underground or above-ground storage tanks, barrels,  wells, pits,
sumps,  lagoons or other  containers of any kind are, or to the actual knowledge
of Seller, have been located in, on, under or about the Real Property.  The Real
Property and every part thereof,  and all operations and activities  therein and
thereon  and  the  use  and  occupancy  thereof,   comply  with  all  applicable
Environmental  Laws,  and neither  Seller nor any person using or occupying  the
Real Property or any part thereof is violating any  Environmental  Laws.  Seller
has all  permits,  licenses  and  approvals  (which are included in the Permits)
required by all applicable  Environmental Laws for the use and occupancy of, and
all  operations  and  activities  in,  the  Real  Property;  Seller  is in  full
compliance with all such permits,  licenses and approvals; and all such permits,
licenses  and  approvals  were duly issued and are in full force and effect.  No
claim, demand,  action or proceeding of any kind relating to any past or present
Release or threatened  Release of any Hazardous  Substances  in, on or under the
Real Property or any past or present violation of any Environmental  Laws at the
Real Property has been made or commenced,  or is pending, or is being threatened
or contemplated by any person.  For purposes of this section 6.1(e),  the phrase
"actual  knowledge  of Seller"  shall mean the  actual  knowledge  of Douglas O.
McKinnon,  the officer of Seller primarily responsible for the Real Property and
the Project, without any duty of special inquiry or investigation.

     (f) There is no litigation,  arbitration  or other legal or  administrative
suit, action,  proceeding or investigation of any kind pending,  or, to the best
of Seller's knowledge,  threatened or being  contemplated,  against or involving
Seller  relating to the Real Property or any part  thereof,  and, to the best of
Seller's knowledge, there is no valid basis for any such litigation, arbitration
or, to the best of  Seller's  knowledge,  other  legal or  administrative  suit,
action,  proceeding  or  investigation.  There is no general  plan,  land use or
zoning action or proceeding of any kind, or general or special assessment action
or  proceeding  of any  kind,  or  condemnation  or  eminent  domain  action  or
proceeding of any kind pending or, to the best of Seller's knowledge, threatened
or being  contemplated  with respect to the Real  Property or any part  thereof.
There is no legal or administrative  action or proceeding  pending to contest or
appeal the amount of real property taxes or assessments  levied against the Real
Property or any part thereof or the assessed  value of the Real  Property or any
part thereof for real property tax purposes. No supplemental real property taxes
have  been or will be  levied  against  or  assessed  with  respect  to the Real
Property  or  any  part  thereof  based  on  any  change  in  ownership  or  new
construction  or other event or occurrence  relating to the Real Property before
the date of this Agreement,  except any such supplemental real property taxes as
have been paid in full and discharged.  The Real Property consists of a separate
tax parcel,  and no real  property  other than the Real Property is assessed for
real property tax purposes as a portion of that tax parcel.

     (e) Seller shall indemnify and defend Buyer against and hold Buyer harmless
from all Claims  arising  from or based on any  failure by Seller to perform all

Seller or condition  that,  after notice or the passage of time, or both,  would
constitute a breach,  default or violation by Seller) under the Contracts or the
Permits  that  occurs  before  the  Closing  Date,  or any  condition,  event or
circumstance  relating to the Real Property that existed or occurred  before the
Closing  Date,  or any personal  injury or property  damage  occurring in, on or
about the Real Property before the Closing Date.

     (f) Seller shall indemnify and defend Buyer against and hold Buyer harmless

7.3 Casualty  Damage.  If, before the Closing Date, the improvements on the
Real  Property  are  damaged  by any  casualty  and  the  cost to  restore  such
improvements,  as  reasonably  determined  by Buyer,  is more  than one  million
dollars  ($1,000,000),  Buyer shall have the right,  by giving  notice to Seller
within  thirty (30) days after  Seller gives  notice of the  occurrence  of such
casualty to Buyer,  to terminate this  Agreement,  in which event this Agreement
shall  terminate.  If the  cost to  restore  such  improvements,  as  reasonably

(30) days  described in this  section 7.3 has expired,  and (if Buyer so elects)
the repair and restoration of the improvements has been completed.

7.4 Eminent Domain. If, before the Closing Date,  proceedings are commenced
for the taking by exercise of the power of eminent  domain of all or any part of
the Property  which,  as reasonably  determined by Buyer,  would render the Real
Property  unacceptable  to Buyer or  unsuitable  for Buyer's  intended use as an
office  building,  Buyer shall have the right, by giving notice to Seller within
thirty  (30)  days  after  Seller  gives  notice  of the  commencement  of  such
proceedings to Buyer, to terminate this Agreement, in which event this Agreement
shall terminate.  If such proceedings are commenced and such taking would render
the Real  Property  unsuitable  for Seller's use under the Lease,  as reasonably
determined  by Seller,  Seller shall have the right,  by giving  notice to Buyer
within thirty (30) days after  commencement  of such  proceedings,  to terminate
this Agreement,  in which event this Agreement shall terminate.  If either Buyer
or Seller  terminate this Agreement  pursuant to this section 7.4,  Seller shall
thereupon  pay Buyer an  amount  equal to all of  Buyer's  costs  calculated  in
accordance  with section  9.3(b),  and the  condemnation  award shall be paid to
Seller.  If Buyer  and/or  Seller  has the  right to  terminate  this  Agreement
pursuant to the preceding  sentence but neither party exercises such right, then
this  Agreement  shall remain in full force and effect and, on the Closing Date,
the condemnation  award (or, if not theretofore  received,  the right to receive
such  award)  payable on account of the taking  shall be  transferred  to Buyer.
Seller shall give notice to Buyer immediately after Seller's receiving notice of
the  commencement  of any proceedings for the taking by exercise of the power of
eminent domain of all or any part of the Property.  Buyer shall have a period of
thirty (30) days (or such shorter  period as Buyer may elect by giving notice to
Seller) after Seller has given the notice to Buyer  required by this section 7.4
to evaluate the extent of the taking and make the determination as to whether to
terminate  this  Agreement.  If  necessary,  the Closing Date shall be postponed
until Seller has given the notice to Buyer  required by this section 7.4 and the
period of thirty (30) days described in this section 7.4 has expired.

(b)  Construction.  Seller  shall  construct  the  Project  in a  good  and
workmanlike  manner in  accordance  with the Plans  and  Specifications  and the

ordinances,  rules, regulations,  building restrictions,  recorded covenants and
restrictions, and requirements of all regulatory authorities having jurisdiction
over  the  Project  or  the  Property  (collectively  the  "Requirements").   If
necessary,  the Plans and  Specifications  shall be  modified to comply with the
Requirements, subject to the provisions of section 7.5(c). Seller represents and

Buyer's prior  written  approval,  except for Minor Changes (as defined  below).
Requests for approval  shall be submitted on a change order form  acceptable  to
Buyer signed by Seller and, if required by Buyer, the project  architect and the
general  contractor,  accompanied by working drawings and a written narrative of
the  proposed  change.  As  conditions  to  its  approval,   Buyer  may  require
satisfactory  evidence of the cost of the proposed change and the time necessary
to complete the proposed change.  Seller acknowledges that this approval process
may result in delays.  Upon Buyer's request,  Seller,  the project architect and
the general  contractor  shall initial the copy of the Plans and  Specifications
delivered  to  and  approved  by,  Buyer  as  a  true  copy  of  the  Plans  and
Specifications for the Project. Seller shall maintain at all times a full set of
the Plans and  Specifications  and any other  working  drawings  for the Project
available  for  inspection by Buyer.  Within thirty (30) days after  Substantial
Completion of the Project, Seller shall deliver to Buyer complete as-built Plans
and Specifications for the completed Project.

     The prior  written  consent of Buyer shall not be  required  for any "Minor
Change"  in the Plans and  Specifications,  meaning a change  which does not (a)
constitute  a material  adverse  change in the  building  material or  equipment
specifications  or the architectural or structural  design,  value or quality of
any of the Project,  or (b) result in a change in Total Project Cost (as defined
below) which causes Total Project Cost to be less than forty-three  million five
hundred thousand dollars  ($43,500,000),  or (c) adversely affect the structural
integrity,  quality of building material or equipment,  or overall efficiency of
operating systems or utility systems of the Project, or (d) require the approval
(which  has not  been  given as of the date of any  such  change)  of any  other
person,  entity,  agency or authority.  The term "Total Project Cost" shall mean
all of the out-of-pocket costs incurred by Seller in acquiring the Real Property
and constructing the Project,  whether incurred before or after the date of this
Agreement, including the following:

          (1) The cost of acquiring the Real Property;

          (2) The cost of  demolishing  and removing any buildings or structures
     on the Real Property prior to  commencement of construction of the Project,
     and the cost of grading  and  otherwise  preparing  the Real  Property  for
     construction of the Project;

          (3) The  costs  of fees and  other  compensation  paid to  architects,
     engineers, and other design professionals in connection with the design and
     planning of the Project;

          (4) The costs of fees and other  compensation  paid to consultants and
     professionals,   including  legal,  accounting,  financial,  political  and
     environmental, necessary or incident to the Project or the determination as
     to the feasibility or practicality thereof;

          (5) The amounts paid to contractors,  subcontractors and suppliers for
     construction of the Project;

          (6) The amount paid by Seller to Buyer pursuant to section 9.3(b); and

          (7) The  costs of  interest  on,  and fees and  expenses  incurred  in
     connection  with,  borrowings  made for the  purpose  of  constructing  the
     Project;
<PAGE>
                                       20


provided,  however,  that  Total  Project  Costs  shall  not  include  (1) costs
(including  legal costs,  title  premiums,  transfer  taxes,  recording fees and
escrow  fees)  incurred  by  Seller  in  connection   with  the   sale-leaseback
transaction contemplated by this Agreement,  except costs specifically described
in  clause  (6)  of the  preceding  sentence,  or (2)  any  costs  incurred  for
equipment,  machinery,  trade  fixtures,  furniture,  furnishings or decorations
installed in the Project. Notwithstanding the foregoing, Seller shall submit all
proposed changes in the Plans and Specifications to Buyer at least ten (10) days
prior to the  commencement  of  construction  relating to such proposed  change,
whether  or not any such  change  is  subject  to  Buyer's  approval;  provided,
however,  that if a change is necessitated by a site condition discovered in the
course  of  the  Project  and  such  ten  (10)  day  notice   requirement  would
unreasonably interfere with the orderly progress of the Project, then Seller may
proceed  with such  change  upon  shorter  notice,  and as to changes  requiring
Buyer's  approval,  Buyer shall  respond to requests for approval as promptly as
practicable.

     previously delivered, such update thereof as Buyer may request.

     (e) Prohibited  Contracts.  Without Buyer's prior written  consent,  Seller
shall not contract for any materials, furnishings,  equipment, fixtures or other
parts or components of the Project,  or other  property for the use or occupancy
of the Property or the Project, if any third party retains or purports to retain
any interest  (other than lien rights,  if any,  created by operation of law) in
such items after their delivery to the Property. Seller shall have five (5) days
to effect the removal of any such retained interest.

     (f) Construction  Responsibilities.  Seller shall be solely responsible for

upon by Seller or any third  party.  Buyer owes no duty of care to Seller or any
third party to protect  against,  or to inform Seller or any third party of, any

or remedies if Seller  defaults in the  performance of any covenant or agreement
to be performed by Seller or if Seller breaches any  representation  or warranty
made by  Seller  in  section  6.1 or in  Seller's  Closing  Certificate.  If any

limitation." The words "approval,"  "consent" and "notice" shall be deemed to be
preceded by the word "written."

     10.6 Further Assurances.  From and after the date of this Agreement, Seller

     10.11 Seller's Default.  In the event of a material breach by Seller in the
performance of its obligations under this Agreement,  Buyer shall have the right
to all remedies it may have against Seller at law or in equity. Without limiting
the generality of the foregoing, Buyer shall have the right to injunctive relief

this  Agreement,  by giving  notice to Seller before the Closing Date, to assign
this Agreement or to have Seller convey, assign and transfer the Property at the
Closing in accordance  with this Agreement to any person  designated by Buyer in

shall  constitute one and the same Agreement.  This Agreement may not be amended
or  modified  except by a written  instrument  signed by Seller and Buyer.  This
Agreement  constitutes  the entire and integrated  agreement  between Seller and
Buyer relating to the purchase and sale of the Property and supersedes all prior
agreements,  understandings,  offers and  negotiations,  oral or  written,  with
respect to the  purchase  and sale of the  Property.  The  covenants,  terms and
conditions of this Agreement shall survive the Closing.

     10.13  Confidentiality.  This  Agreement  is  entered  into by Buyer on the
condition, and Seller covenants, that Seller shall not disclose the existence of
this  Agreement and its terms to any person,  except on a strictly  confidential
basis to the Escrow Company, to Title Company, to Seller's  contractors,  and to
Seller's   partners  and  their  respective   partners,   directors,   officers,
affiliates,  employees  and  advisors,  who are  directly  involved  in Seller's
obligations under this Agreement and to Seller's lenders. Seller shall not make,
and Seller shall use its best efforts to ensure that the foregoing third parties
do not make,  any public  announcement  of this  Agreement  or the  transactions
contemplated by this Agreement without the prior consent of Buyer, which consent
may be withheld by Buyer in its sole and absolute discretion, unless such public
announcement  is  necessary  to comply  with  applicable  law.  Buyer  shall not
disclose any confidential or proprietary  information  regarding the business or
financial condition of Seller to any person,  except on a strictly  confidential
basis to Buyer's contractors,  and to Buyer's directors,  officers,  affiliates,
employees and advisors,  who are directly involved in Seller's obligations under
this Agreement, or as such disclosure may be necessary to comply with applicable
law.

     IN WITNESS WHEREOF, Seller and Buyer have executed this Agreement as of the
date first hereinabove written.

                                      LEASE



     THIS LEASE,  made as of the date specified in the Basic Lease  Information,
by  and  between  the  landlord   specified  in  the  Basic  Lease   Information
("Landlord"),   and  the  tenant  specified  in  the  Basic  Lease   Information
("Tenant"),


                              W I T N E S S E T H:


                                    ARTICLE 1

                                    Premises

     1.1  Landlord  hereby  leases to Tenant,  and  Tenant  hereby  leases  from
Landlord,  for the term and subject to the covenants  hereinafter  set forth, to
all of which  Landlord and Tenant  hereby agree,  the building  specified in the
Basic  Lease  Information  (the  "Building")  containing  approximately  239,749
rentable  square  feet of space,  and the land on which the  Building is located
(such land,  together with the Building and the other  improvements  thereon are
referred to herein, collectively, as the "Premises").


                                    ARTICLE 2

                                      Term

     2.1 The term of this Lease shall be the term  specified  in the Basic Lease
Information,  which shall  commence on the  commencement  date  specified in the
Basic Lease Information (the "Commencement  Date") and, unless sooner terminated
as hereinafter provided, shall end on the expiration date specified in the Basic
Lease Information (the "Expiration Date").

     2.2 If the  Commencement  Date is not the  first day of a  calendar  month,
Tenant shall pay to Landlord,  as additional  rent,  the Base Rent payable under
section  3.1,  calculated  on  a  per  diem  basis,  for  the  period  from  the
Commencement  Date until the first day of the next full calendar  month.  Tenant
shall  pay  the  Base  Rent  in  respect  of  such  period  to  Landlord  on the
Commencement Date.

     2.3 Tenant  shall accept the  Premises  "as is" on the  Commencement  Date.
Landlord  shall have no obligation to construct or install any  improvements  in
the Premises.  Tenant  acknowledges that, prior to the Commencement Date, Tenant
occupied the  Premises.  Tenant's  possession of the Premises  shall  constitute
Tenant's  acknowledgment  that the Premises are in all respects in the condition
in which Landlord is required to deliver the Premises to Tenant under this Lease
and that Tenant has  examined  the  Premises  and is fully  informed to Tenant's
satisfaction of the physical and environmental  condition and the utility of the
Premises.  Tenant acknowledges that Landlord, its agents and employees and other
persons acting on behalf of Landlord have made no  representation or warranty of
any kind in connection with any matter relating to the physical or environmental
condition,  value,  fitness, use or zoning of the Premises upon which Tenant has
relied directly or indirectly for any purpose.

     2.4 Provided that Tenant is not in monetary or other material default under
or breach of this Lease,  either at the time of exercising the applicable option
to renew  described  below or at the time such  renewal term  commences,  Tenant
shall have the option to renew  this Lease for two (2)  additional  terms of ten
(10) years each.  Tenant shall  exercise  each option to renew by  delivering to
Landlord written notice of Tenant's  election to renew the term of this Lease at
least  eighteen (18) months before the expiration of the  then-existing  term of
this Lease.  Landlord's failure to receive Tenant's written notice duly electing
to renew the term of this Lease shall be conclusively  deemed Tenant's  election
not to exercise its option to renew, in which event the term shall expire on the
last day of the then-existing term. If Tenant duly exercises an option to renew,
then  Tenant  shall  continue  to occupy  the  Premises  on all of the terms and
conditions  of this  Lease,  except  that:  (a) the Base Rent  payable by Tenant
during the  applicable  renewal  term shall be increased as set forth in section
3.1(a);  and (b) after the second  renewal  term,  Tenant  shall have no further
renewal  options  under this Lease.  Tenant's  rights to extend the term of this
Lease are  personal  to Tenant,  may not be  exercised  by or be assigned to any
person or entity  other than  Tenant or a  Corporate  Successor  (as  defined in
section  12.1),  and  shall  terminate  and be of no  further  effect  upon  any
assignment of this Lease or subletting of all or any part of the Premises to any
person or entity.


                                    ARTICLE 3

                                      Rent

     3.1 Tenant shall pay to Landlord the following amounts as base monthly rent
for the Premises ("Base Rent"):

     (a) During the period between the Commencement Date and the last day of the
twelfth full calendar month thereafter,  Tenant shall pay to Landlord the amount
of monthly rent  specified in the Basic Lease  Information  (the  "Initial  Base
Rent").  Commencing on the first day of the thirteenth full calendar month after
the  Commencement  Date,  and on  each  anniversary  of  that  date  thereafter,
including during all renewal terms (each, an "Adjustment  Date"),  the Base Rent
shall be increased to an amount equal to the greater of:

          (i)  the  sum  of (A)  the  Base  Rent  in  effect  during  the  month
     immediately  preceding the Adjustment Date, plus (B) the product of (1) the
     Base Rent in effect during the month  immediately  preceding the Adjustment
     Date, multiplied by (2) the lesser of (x) three percent (3.0%), and (y) the
     product of two (2),  multiplied by the percentage  increase in the Consumer
     Price Index (as defined  below)  measured from the last month for which the
     Consumer  Price Index is published  immediately  preceding  the date twelve
     (12) months prior to the Adjustment  Date in question to the last month for
     which the Consumer Price Index is published  immediately  preceding the CPI
     Adjustment Date in question; and
<PAGE>
                                       3


          (ii) the  lesser  of (A) the  Initial  Base  Rent  increased  by three
     percent  (3%)  per  year,  compounded,  from the  Commencement  Date to the
     Adjustment Date in question,  and (B) the sum of (1) an amount equal to the
     Initial  Base  Rent,  plus (2) the  product  of (x) an amount  equal to the
     Initial Base Rent,  multiplied by (y) the product of two (2), multiplied by
     the percentage  increase in the Consumer Price Index measured from the last
     month for which the Consumer Price Index is published immediately preceding
     the Commencement  Date to the last month for which the Consumer Price Index
     is published immediately preceding the Adjustment Date in question;

provided,  however,  that in no event  shall the Base Rent after any  Adjustment
Date be less than the product of an amount  equal to the Base Rent in effect for
the month immediately  preceding such Adjustment Date, multiplied by one hundred
one and one-half percent (101.5%).

     (b) Landlord and Tenant each shall, promptly after any determination of the
Base Rent pursuant to section 3.1(a), execute and deliver to the other a written
confirmation  which sets forth the Base  Rent,  but such Base Rent shall  become
effective whether or not such confirmation is executed.

     (c) As used in this Lease,  "Consumer  Price Index" shall mean the Consumer
Price Index for All Cities,  All Urban  Consumers,  All Items,  1982-1984 equals
100,  published  by the  United  States  Department  of  Labor,  Bureau of Labor
Statistics.  If the comparison Consumer Price Index required for the calculation
specified in section 3.1(a) is not available on the Adjustment Date in question,
Tenant  shall to pay, as of such  Adjustment  Date,  one hundred  three  percent
(103%) of the Base Rent payable  during the period  immediately  preceding  such
Adjustment  Date until the Consumer  Price Index is available  and the necessary
calculation  is  made.  As  soon as  such  calculation  is  made,  Tenant  shall
immediately pay to Landlord or Landlord shall credit Tenant (as the case may be)
the  amount of any  underpayment  or  overpayment  of Base Rent for the month or
months that may have elapsed  pending the  calculation  of the Base Rent for the
Adjustment  Date in  question.  If the federal  government  revises or ceases to
publish the  Consumer  Price  Index,  this  section 3.1 shall  automatically  be
amended to provide that, as of each  Adjustment Date  thereafter,  the Base Rent
shall be one hundred  three percent  (103%) of the Base Rent payable  during the
period immediately preceding such Adjustment Date.

                                       4


     (d)  Throughout  the term of this Lease,  Tenant  shall pay, as  additional
rent,  all Other Taxes (as defined in section 5.3),  all Operating  Expenses (as
defined in section 5.1) and all other  amounts of money and charges  required to
be paid by Tenant  under this  Lease,  whether  or not such  amounts of money or
charges are designated  "additional  rent." As used in this Lease,  "rent" shall
mean and  include  all Base  Rent and  additional  rent  payable  by  Tenant  in
accordance with this Lease.

     3.2 It is the  intention  of Landlord and Tenant that the Base Rent payable
by Tenant to Landlord  during the entire term of this Lease shall be  absolutely
net of all  costs and  expenses  incurred  in  connection  with the  management,
operation,  maintenance,  repair and  replacement  of the Premises in accordance
with this Lease,  except as expressly  provided in section 8.3.  Landlord  shall
have no  obligations  or  liabilities  whatsoever  with respect to the costs and
expenses of  management,  operation,  maintenance,  repair or replacement of the
Premises during the term of this Lease,  except as expressly provided in section
8.3,  and  Tenant  shall pay all  costs  and  expenses  incurred  in  connection
therewith.  Without  limiting the  generality of the  foregoing,  throughout the
entire term of this Lease,  Tenant shall pay, as additional  rent, all Operating
Expenses (as defined in section 5.1) that accrue  during or are allocable to the
term of this Lease.

     3.3 Tenant  shall pay all Base Rent to Landlord,  in advance,  on or before
the first day of each and every  calendar  month  during the term of this Lease.
Tenant shall pay all additional  rent upon demand.  Tenant shall pay all rent to
Landlord  without notice,  demand,  deduction or offset,  in lawful money of the
United  States of America,  at the address of  Landlord  specified  in the Basic
Lease  Information,  or to such other  person or at such other place as Landlord
may from time to time designate in writing.

     3.4 Tenant acknowledges that the late payment by Tenant of any Base Rent or
additional  rent  (including  the items  described  in  section  3.2) will cause
Landlord to incur costs and  expenses,  the exact  amount of which is  extremely
difficult  and  impractical  to  fix.  Such  costs  and  expenses  will  include
administration  and collection  costs and  processing  and accounting  expenses.
Therefore,  if any Base Rent or  additional  rent is not  received  by  Landlord
within five (5) Business Days (as defined  below) after it is due,  Tenant shall
immediately  pay to  Landlord a late charge  equal to six  percent  (6%) of such
delinquent  amount. The term "Business Days" means any day other than Saturdays,
Sundays  and  days on  which  national  banks  are  permitted  to be  closed  in
accordance with Federal banking laws and regulations.  Landlord and Tenant agree
that such  late  charge  represents  a  reasonable  estimate  of such  costs and
expenses and is fair  compensation to Landlord for the loss suffered by Tenant's
failure to make timely payment.  In no event shall such late charge be deemed to
grant to Tenant a grace period or extension of time within which to pay any rent
or prevent  Landlord from exercising any right or enforcing any remedy available
to  Landlord  upon  Tenant's  failure  to pay all rent due under this Lease in a
timely  fashion,  including  the right to terminate  this Lease.  All amounts of
money payable by Tenant to Landlord hereunder,  if not paid when due, shall bear
interest from the due date until paid at a rate (the "Interest  Rate") per annum
equal to five (5)  percentage  points plus the prime or reference rate announced
from time to time by Bank of America N.T.&S.A.  (the "Reference Rate"), provided
that the Interest Rate shall at no time exceed twelve percent (12%) per annum.

                                    ARTICLE 4

                          Payment of Operating Expenses

     4.1(a) In addition to the Base Rent payable  during the term of this Lease,
Tenant  shall pay to  Landlord,  as  additional  rent,  an  amount  equal to the
Operating Expenses paid or incurred by Landlord in any calendar year (or partial
year)  during  the term of this  Lease.  If it shall not be lawful for Tenant to
reimburse Landlord for any Operating Expenses,  as defined herein, the Base Rent
payable to Landlord  shall be  increased  to net Landlord the same net Base Rent
after payment of such Operating Expenses as would have been received by Landlord
prior to the payment of such Operating Expenses.

     (b)  During  December  of  each  calendar  year or as  soon  thereafter  as
practicable,  Landlord  shall give Tenant  notice of its estimate of the amounts
payable pursuant to section 4.1(a) above for the succeeding calendar year. On or
before the first day of each month during the succeeding  calendar year,  Tenant
shall pay to Landlord,  as additional rent, one twelfth (1/12) of such estimated
amounts. If Landlord fails to deliver such notice to Tenant in December,  Tenant
shall  continue  to pay  Operating  Expenses  on the basis of the  prior  year's
estimate  until the first day of the next  calendar  month  after such notice is
given,  provided  that on such date Tenant  shall pay to Landlord  the amount of
such estimated  adjustment  payable to Landlord for prior months during the year
in question,  less any portion thereof previously paid by Tenant. If at any time
it appears to Landlord that the amounts  payable  under this section  4.1(b) for
the current calendar year will vary from Landlord's  estimate,  Landlord may, by
giving written notice to Tenant,  revise Landlord's  estimate for such year, and
subsequent  payments  by  Tenant  for such year  shall be based on such  revised
estimate.

     (c)(i)  Within ninety (90) days after the close of each calendar year or as
soon after such ninety (90) day period as practicable, Landlord shall deliver to
Tenant a statement of the amounts  payable under  section  4.1(a) above for such
calendar year (the "annual  statement")  and such  statement  shall be final and
binding upon Landlord and Tenant, subject to the terms of section 4.1(c)(ii). If
on the  basis of such  statement  Tenant  owes an  amount  that is more than the
estimated  payments for such calendar  year  previously  made by Tenant,  Tenant
shall pay the deficiency to Landlord  within fifteen (15) days after delivery of
the statement.  If on the basis of such statement Tenant has paid to Landlord an
amount in excess of the  amounts  payable  under  section  4.1(a)  above for the
preceding  calendar year and Tenant is not in default in the  performance of any
of its covenants under this Lease,  then Landlord,  at its option,  shall either
promptly  refund such excess to Tenant or credit the amount  thereof to the Base
Rent next becoming due from Tenant until such credit has been exhausted.
<PAGE>
                                       6


     (ii) Tenant shall have the right,  during the one hundred  eighty (180) day
period  following  delivery of an annual  statement,  at  Tenant's  sole cost to
review in Landlord's  offices  Landlord's records of Operating Expenses and Real
Property Taxes for the subject  calendar year.  Such review shall be carried out
only by regular employees of Tenant or by a "Big Six" accounting firm and not by
any other third party.  No person  conducting such an audit shall be compensated
on a "contingency" or other incentive basis. If, as of the one hundred eightieth
day after  delivery  to Tenant of an  annual  statement,  Tenant  shall not have
delivered  to Landlord an  objection  statement  (as defined  below),  then such
annual statement shall be final and binding upon Landlord and Tenant, and Tenant
shall have no further right to object to such annual  statement.  If within such
one  hundred  eighty  (180) day  period,  Tenant  delivers to Landlord a written
statement  specifying   objections  to  such  annual  statement  (an  "objection
statement"),  then  Tenant and  Landlord  shall meet to attempt to resolve  such
objection within thirty (30) days after delivery of the objection statement.  If
such objection is not resolved  within such thirty (30) day period,  then either
party shall have the right to require  that the dispute be  submitted to binding
arbitration   under  the  rules  of  the   American   Arbitration   Association.
Notwithstanding  that any  such  dispute  remains  unresolved,  Tenant  shall be
obligated to pay Landlord all amounts  payable in  accordance  with this section
4.1 (including any disputed amount).  If such dispute results in an agreement or
an  arbitrator's  determination  that Tenant is  entitled to a refund,  Landlord
shall, at its option, either pay such refund or credit the amount thereof to the
Base Rent next becoming due from Tenant.

     (d) If this Lease terminates on a day other than the last day of a calendar
year,  the amounts  payable by Tenant under section 4.1(a) above with respect to
the  calendar  year in which such  termination  occurs  shall be prorated on the
basis which the number of days from the  commencement  of such calendar year, to
and including such termination date, bears to 360. The termination of this Lease
shall not affect the  obligations  of  Landlord  and Tenant  pursuant to section
4.1(c) above to be performed after such termination.

Landlord  written notice of such contest and the nature thereof and Tenant shall

                                       Use

     6.1 The Premises shall be used only for the purpose  specified in the Basic
Lease Information and no other purpose without Landlord's prior written consent,
which consent shall not be unreasonably withheld or delayed; provided,  however,
Landlord's  withholding of consent shall be conclusively  presumed reasonable if
the proposed use would  materially  increase the wear and tear on or the risk of
damage to the Premises above levels or risks  resulting from Tenant's use of the
Premises  exclusively  for  office  purposes  or if the  proposed  use is for an
illegal,  immoral or disreputable purpose; and provided,  further, that only the
Tenant originally named herein, and no subtenant, assignee or other successor to
such  original  Tenant,  shall  have the right to use the  Premises  or any part
thereof for any purpose other than office use.  Notwithstanding  anything to the
contrary in the Basic Lease Information,  (a) Tenant's right to use the Premises
or any part  thereof for any use other than  general  office use (whether or not
such  other use is listed in the Basic  Lease  Information)  is  subject  to the
following conditions:  (i) such ancillary  (non-office) uses shall be limited to
areas  comprising  less than thirty percent (30%) of the total  rentable  square
footage  of the  building  in the  aggregate,  and (ii) all such  uses  shall be
consistent with Tenant's  obligations  under Articles 11 and 21 hereof;  and (b)
any  subtenant  or assignee of the  original  Tenant  named herein shall use the
Premises  exclusively  for office  purposes and no other use shall be permitted,
except that the  original  Tenant  named herein may sublease the portions of the
Premises  to be used as an  employee  cafeteria  or  child  care  center  to the
operators of those  facilities.  Tenant shall not do or permit to be done in, on
or about  the  Premises,  nor  bring or keep or  permit  to be  brought  or kept
therein,  anything  which is  prohibited by or will in any way conflict with any
law, ordinance, rule, regulation or order now in force or which may hereafter be
enacted,  or which is prohibited by any  insurance  policy for the Premises,  or
will in any way increase the existing  rate of, or cause a  cancellation  of, or
affect any insurance for the Premises. Tenant shall not do or permit anything to
be done in, on or about the Premises which will in any way obstruct or interfere
with the rights of  Landlord.  Tenant  shall not maintain or permit any nuisance
in, on or about the Premises or commit or suffer to be  committed  any waste in,
on or about the Premises.

such other services as Landlord determines to furnish to the Premises.  Landlord
shall not be in default  hereunder or be liable for any damage or loss  directly
or indirectly  resulting from, nor shall the rent be abated or a constructive or
other eviction be deemed to have occurred by reason of, the installation, use or
interruption of use of any equipment in connection with the furnishing of any of
the foregoing  services,  any failure to furnish or delay in furnishing any such
services,  whether such failure or delay is caused by accident or any  condition
beyond  the  control  of  Landlord  or Tenant or by the  making  of  repairs  or
improvements  to the  Premises,  or any  limitation,  curtailment,  rationing or
restriction on use of water, electricity,  gas or any form of energy serving the
Premises,  whether such  results  from  mandatory  governmental  restriction  or
voluntary  compliance with  governmental  guidelines.  Tenant shall pay the full
cost of all of the  foregoing  services as additional  rent in  accordance  with
Article 4.

                                    ARTICLE 8

                  Maintenance and Repairs; Capital Improvements

     8.1  Landlord  shall,  at all times  during  the term of this  Lease and at
Tenant's  sole cost and expense  (except as otherwise  provided in section 8.3),
maintain,  repair  and  replace  the  Premises  and every part  thereof  and all
grounds, landscaping, parking areas, lighting, roof, walls, floors, foundations,
signs,  heating,  ventilating  and  air  conditioning,  mechanical,  electrical,
plumbing, sprinkler and life safety systems, equipment,  fixtures,  alterations,
additions  and  improvements  therein or thereon  and keep all of the  foregoing
clean and in good order and operating condition (including painting the exterior
of the Premises as often as  reasonably  needed to keep such exterior in a good,
well painted condition, cleaning interior and exterior doors, windows and glass,
and  repairing  and  replacing  any  exterior  windows and glass that is broken,
cracked  or  damaged).   Landlord  shall  engage  a  duly  licensed  independent
contractor  to perform  all  maintenance  and repair  services  on all  heating,
ventilating and air conditioning,  mechanical,  electrical,  plumbing, sprinkler
and life safety systems and equipment in the Premises that is to be performed by
Landlord in accordance with this section 8.1. Tenant hereby waives all rights to
make  repairs  at the  expense  of  Landlord  or in lieu  thereof  to vacate the
Premises.  Subject to section 9.2,  Tenant shall, at the end of the term of this
Lease,  surrender  to Landlord  the  Premises  and all  alterations,  additions,
fixtures  and  improvements  therein or thereto  in the same  condition  as when
received,  ordinary wear and tear and damage  thereto by fire or other  casualty
excepted.

     8.2 In the event  Landlord  fails to  perform  any  maintenance  and repair
obligation  under section 8.1 within fifteen (15) days after Tenant  delivers to
Landlord  notice  specifying  such  obligation  (or such longer period as may be
reasonably required due to the nature of such obligation), then Tenant may, upon
a further ten (10) days'  notice to  Landlord,  perform at Tenant's  own expense
such obligation  (unless  Landlord cures its  nonperformance  within such 10-day
period).  Notwithstanding  the foregoing,  in the event that (i)  maintenance or
repairs  are,  in  Tenant's  reasonable  judgment,  urgently  required  to avoid
material  disruption of or interference  with the operation of Tenant's business
on the  Premises  or to avoid  imminent  danger to health  or  safety,  and (ii)
Landlord,  having  received  notice  thereof,  does not, in Tenant's  reasonable
judgment,  commence  with  appropriate  promptness  and pursue with  appropriate
diligence  the  required  maintenance  or repairs,  then Tenant may perform such
maintenance  or repairs  without  waiting for the time  periods set forth in the
preceding sentence.

     8.3 To the extent included within the definition of "Operating Expenses" in
section 5.1, the costs incurred by Landlord in performing its obligations  under
section  8.1 shall be  recoverable  from  Tenant  pursuant  to Article 4. To the
extent such costs are excluded from the definition of "Operating Expenses," such
costs shall be Landlord's responsibility, subject to Landlord's right to collect
reserves for  anticipated  capital  repairs,  improvements  and  replacements in
accordance  with the definition of "Operating  Expenses".  In the event that the
cost of any such  capital  repairs,  improvements  or  replacements  exceeds the
amount that Landlord has specified to be reserved therefor,  Landlord shall bear
such cost to the extent of such excess.

                                    ARTICLE 9

                                   Alterations

     9.1 Tenant shall not make any alterations,  additions or improvements in or
to the  Premises  or any part  thereof,  or attach  any  fixtures  or  equipment
thereto,  without  Landlord's prior written consent,  which consent shall not be
unreasonably withheld.  Notwithstanding the preceding sentence,  Tenant may make
such alterations,  additions or improvements  without Landlord's consent only if
the total cost of such alterations,  additions or improvements is fifty thousand
dollars ($50,000) or less and such  alterations,  additions or improvements will
not affect in any way the structural,  exterior or roof elements of the Premises
or  mechanical,  electrical,  plumbing,  utility or life  safety  systems of the
Premises,  but Tenant shall give prior written  notice of any such  alterations,
additions or improvements to Landlord.  In no event shall Tenant be permitted to
install  underground storage tanks (excepting a single 20,000 gallon water tank)
or  fuel  systems  on  the  Premises.  Landlord's  refusal  to  consent  to  the
installation  of an  underground  tank  or fuel  system  shall  be  conclusively
presumed to be reasonable. All alterations,  additions and improvements in or to
the Premises to which Landlord consents shall be made by Tenant at Tenant's sole
cost and expense as follows:

     (a) Tenant shall  submit to  Landlord,  for  Landlord's  written  approval,
complete plans and specifications for all work to be done by Tenant.  Such plans
and  specifications   shall  be  prepared  by  the  licensed   architect(s)  and
engineer(s), shall comply with all applicable codes, laws, ordinances, rules and
regulations, shall not adversely affect the structural elements of the Premises,
shall  be in a  form  sufficient  to  secure  the  approval  of  all  government
authorities  with  jurisdiction  over  the  Premises,  and  shall  be  otherwise
satisfactory to Landlord in Landlord's reasonable discretion.

     (b) Landlord  shall notify Tenant in writing,  within fifteen (15) Business
Days after Landlord's receipt of such plans and specifications, whether Landlord
approves  or  disapproves  such  plans  and  specifications   and,  if  Landlord
disapproves such plans and  specifications,  Landlord shall describe the reasons
for disapproval.  Tenant may submit to Landlord revised plans and specifications
for Landlord's prior written approval. Tenant shall pay all costs, including the
fees and expenses of the licensed  architect(s)  and  engineer(s),  in preparing
such plans and specifications.
<PAGE>
                                       15


     (c) All changes in the plans and specifications  approved by Landlord shall
be subject to Landlord's  prior written  approval.  If Tenant wishes to make any
such change in such approved  plans and  specifications,  Tenant shall have such
architect(s) and engineer(s)  prepare plans and  specifications  for such change
and submit them to Landlord for  Landlord's  written  approval.  Landlord  shall
notify Tenant in writing promptly whether Landlord  approves or disapproves such
change and, if Landlord  disapproves  such change,  Landlord  shall describe the
reasons  for  disapproval.  Tenant  may  submit to  Landlord  revised  plans and
specifications for such change for Landlord's written approval. After Landlord's
written approval of such change,  such change shall become part of the plans and
specifications approved by Landlord.

     (d) Tenant  shall  obtain and comply  with all  building  permits and other
governmental  permits and approvals required in connection with the work. Tenant
shall, through Tenant's licensed  contractor,  perform the work substantially in
accordance  with  (i) the  plans  and  specifications  approved  in  writing  by
Landlord,  (ii) the permits obtained by Tenant,  and (iii) all applicable codes,
laws, ordinances,  rules and regulations.  Tenant shall pay, as additional rent,
the entire cost of all work (including the cost of all utilities, permits, fees,
taxes, and property and liability  insurance  premiums in connection  therewith)
required  to  make  the  alterations,   additions  and  improvements.  Under  no
circumstances  shall Landlord be liable to Tenant for any damage,  loss, cost or
expense  incurred  by  Tenant  on  account  of  any  plans  and  specifications,
contractors or subcontractors,  design of any work, construction of any work, or
delay in completion of any work.

     (e)  Tenant  shall give  written  notice to  Landlord  of the date on which
construction  of any work will be commenced at least ten (10) days prior to such
date. Tenant shall keep the Premises free from mechanics', materialmen's and all
other  liens  arising  out of any  work  performed,  labor  supplied,  materials
furnished or other  obligations  incurred by Tenant.  Tenant shall  promptly and
fully pay and  discharge all claims on which any such lien could be based or, in
the event Tenant  reasonably  disputes the validity or amount of any such claim,
Tenant may bond over such lien to Landlord's reasonable  satisfaction.  Landlord
shall have the right to post and keep posted on the  Premises  any notices  that
may be  provided  by law or  which  Landlord  may  deem  to be  proper  for  the
protection of Landlord and the Premises  from such liens,  and to take any other
action  Landlord deems necessary to remove or discharge liens or encumbrances at
the expense of Tenant.

     9.2  All  alterations,   additions,  fixtures  and  improvements,   whether
temporary or permanent in  character,  made in or to the Premises by Landlord or
Tenant,  shall become part of the Premises and  Landlord's  property  excluding,

however,  underground  tanks which shall remain the property of Tenant and shall
be  registered  in the name of Tenant so long as this  Lease  remains in effect.
Upon  termination of this Lease,  Landlord  shall have the right,  at Landlord's
option, by giving written notice to Tenant at any time before or within ten (10)
days after such termination, to retain all such alterations, additions, fixtures
and improvements in the Premises,  without  compensation to Tenant, or to remove
all such  alterations,  additions,  fixtures and improvements from the Premises,
repair all damage  caused by any such  removal,  and restore the Premises to the
condition  in which the Premises  existed  before such  alterations,  additions,
fixtures and improvements  were made, and in the latter case Tenant shall pay to
Landlord,  upon  billing  by  Landlord,  the cost of such  removal,  repair  and
restoration   (including  a  reasonable  charge  for  Landlord's  oversight  and
administration  of  such  work).  Notwithstanding  the  foregoing,  all  movable
furniture,  equipment,  trade fixtures (including the video screen walls, visual
systems,  projectors  and  related  equipment  in Tenant's  service  reliability
center) and other personal  property  shall remain the property of Tenant.  Upon
termination of this Lease,  Tenant shall, at Tenant's  expense,  remove all such
movable  furniture,  equipment,  trade fixtures other personal property from the
Premises and repair all damage caused by any such removal.  Termination  of this
Lease shall not affect the obligations of Tenant pursuant to this section 9.2 to
be performed after such termination.

                                    Insurance

     10.1  Landlord  shall not be liable to Tenant  for any damage to or loss or
theft of any property or for any bodily or personal injury,  illness or death of
any person in, on or about the  Premises  arising at any time and from any cause
whatsoever,  except to the  extent  caused by the gross  negligence  or  willful
misconduct of Landlord.  Tenant waives all claims against  Landlord arising from
any liability described in this section 10.1, except to the extent caused by the
gross negligence or willful misconduct of Landlord.

     10.2 Tenant shall indemnify and defend  Landlord  against and hold Landlord
harmless  from all claims,  demands,  liabilities,  damages,  losses,  costs and
expenses,  including reasonable attorneys' fees and disbursements,  arising from
or related to any use or  occupancy  of the  Premises,  or any  condition of the
Premises,  or any default in the  performance  of Tenant's  obligations,  or any
damage to any property  (including property of employees and invitees of Tenant)
or any bodily or  personal  injury,  illness  or death of any person  (including
employees and invitees of Tenant)  occurring in, on or about the Premises or any
part  thereof or any part of the  building or the land  containing  the Premises
arising at any time and from any cause  whatsoever  (except to the extent caused
by the gross negligence or willful  misconduct of Landlord) or occurring outside
the Premises when such damage,  bodily or personal  injury,  illness or death is
caused by any act or  omission  of Tenant or its  agents,  officers,  employees,
contractors,  invitees  or  licensees.  This  section  10.2  shall  survive  the
termination of this Lease with respect to any damage, bodily or personal injury,
illness or death occurring prior to such termination.

     10.3  Tenant  shall,  at all  times  during  the term of this  Lease and at
Tenant's  sole cost and  expense,  obtain and keep in force  commercial  general
liability insurance, including contractual liability (specifically covering this
Lease), cross liability,  fire legal liability, and premises operations,  all on
an "occurrence"  policy form, with a minimum combined single limit in the amount
specified in the Basic Lease  Information  per occurrence for bodily or personal
injury to, illness of, or death of persons and damage to property  occurring in,
on or about the Premises,  such insurance  shall name the Landlord and any other
parties designated by Landlord,  or any other party with an insurable  interest,
as  additional  insureds.  Tenant shall,  at Tenant's sole cost and expense,  be
responsible for insuring Tenant's  furniture,  equipment,  fixtures,  computers,
office machines and personal property.

     10.4  Tenant  shall,  at all  times  during  the term of this  Lease and at
Tenant's sole cost and expense,  obtain and keep in force worker's  compensation
and employer's  liability  insurance in all states in which the Premises and any
other  operations  of the Tenant are  located  and any other  state in which the
Tenant or its contractors or  subcontractors  may be subject to any statutory or
other  liability  arising in any manner  whatsoever out of the actual or alleged
employment  of others.  The total limits of the  employer's  liability  coverage
required hereunder shall not be less than the amounts specified in section 10.3.

     10.5 The insuring party for property insurance specified in the Basic Lease
Information  shall,  at all times during the term of this Lease, at such party's
sole cost and expense,  obtain and keep in force (a)  insurance  against loss or
damage to the  Premises by fire and all other risks of physical  loss covered by
insurance  of the type now known as "all risk," with  difference  in  conditions
coverage,  in an amount not less than the full  replacement cost of the Premises
(without deduction for depreciation),  including the cost of debris removal, and
such endorsements as Landlord may reasonably require, including the "Replacement
Cost Endorsement"; (b) boiler and machinery insurance covering pressure vessels,
air tanks, boilers,  machinery,  pressure piping,  heating,  ventilation and air
conditioning  equipment,  and elevator  and  escalator  equipment,  provided the
Premises  contain  equipment  of  such  nature  and  insurance  against  loss of
occupancy or use arising from any  breakdown of any such items,  in such amounts
as Landlord  may  reasonably  determine;  and (c) plate glass  insurance in such
amounts as Landlord may reasonably determine if the Premises contain plate glass
[Add flood  insurance?].  In addition to the  insurance  specifically  described
above,  Tenant  shall  obtain  and keep in force such  other  insurance  (or the
above-described  insurance  at  increased  limits) as  Landlord  may  reasonably
require from time to time.

     10.6 All  insurance  required to be maintained by Tenant under this Article
10 and all renewals  thereof shall be issued by good and  responsible  companies
qualified  to do and doing  business in the state where the Premises are located
and having a rating in Best's  Insurance  Guide of at least A-XI. All deductible
amounts under each such  insurance  policy shall be subject to Landlord's  prior
written approval. Each policy to be maintained by Tenant shall expressly provide
that the policy shall not be canceled or altered  without sixty (60) days' prior
written notice to Landlord and shall remain in effect  notwithstanding  any such
cancellation  or alteration  until such notice shall have been given to Landlord
and such period of sixty (60) days shall have expired.  All insurance under this
Article 10 to be  maintained by Tenant shall name Landlord and any other parties
designated  by Landlord,  or any other party with an insurable  interest,  as an
additional insured or loss payee, shall be primary and noncontributing  with any
insurance which may be carried by Landlord, shall afford coverage for all claims
based on any act,  omission,  event or condition  that occurred or arose (or the
onset of which occurred or arose) during the policy period,  and shall expressly
provide  that  Landlord,   although  named  as  an  additional  insured,   shall
nevertheless  be  entitled to recover  under the policy for any loss,  injury or
damage to Landlord.  Upon the issuance of each such policy to be  maintained  by
Tenant,  Tenant  shall  deliver  each  such  policy  or a  certified  copy and a
certificate  thereof to Landlord for  retention by Landlord.  If Tenant fails to
insure or fails to furnish  to  Landlord  upon  notice to do so any policy to be
maintained  by Tenant or  certified  copy and  certificate  thereof as required,
Landlord shall have the right from time to time to effect such insurance for the
benefit of Tenant or Landlord or both of them and all premiums  paid by Landlord
shall be payable by Tenant as  additional  rent on demand.  Tenant  shall pay to
Landlord,  immediately upon demand all costs incurred by Landlord as a result of
Tenant's  failure to obtain and  maintain in effect the  policies  of  insurance
required under this Article 10.

     10.7  Tenant  waives on  behalf  of all  insurers  under  all  policies  of
property, liability and other insurance (excluding workers' compensation) now or
hereafter carried by Tenant insuring or covering the Premises, or any portion or
any contents thereof, or any operations therein, all rights of subrogation which
any insurer might  otherwise,  if at all,  have to any claims of Tenant  against
Landlord.  Landlord  waives on  behalf of all  insurers  under all  policies  of
property, liability and other insurance (excluding workers' compensation) now or
hereafter  carried by Landlord  insuring or covering the Premises or any portion
or any contents thereof,  or any operations  therein,  all rights of subrogation
which any insurer  might  otherwise,  if at all,  have to any claims of Landlord
against  Tenant.  Tenant shall,  prior to or immediately  after the date of this
Lease,  procure  from each of the  insurers  under  all  policies  of  property,
liability and other insurance (excluding workers' compensation) now or hereafter
carried by Tenant  insuring  or  covering  the  Premises,  or any portion or any
contents  thereof,  or  any  operations  therein,  a  waiver  of all  rights  of
subrogation which the insurer might otherwise,  if at all, have to any claims of
Tenant against Landlord as required by this section 10.6.

                       Compliance With Legal Requirements

     11.1 Tenant shall, at Tenant's sole cost and expense,  promptly comply with
all of the following  (collectively,  "Legal  Requirements")  laws,  ordinances,
rules,  regulations,  orders and other  requirements of any government or public
authority now in force or which may hereafter be in force, with all requirements
of any  board of fire  underwriters  or  other  similar  body  now or  hereafter
constituted,  with all directions and  certificates of occupancy issued pursuant
to any  law by  any  governmental  agency  or  officer  and  with  all  recorded
covenants,  conditions or restrictions,  insofar as any thereof relate to or are
required by the  condition,  use or occupancy of the Premises or the  operation,
use or maintenance of any personal property, fixtures,  machinery,  equipment or
improvements in the Premises. Tenant's obligations under this Section 11.1 shall
include the obligation to make  alterations or  improvements  to the Premises if
required to comply with any Legal Requirements.

                                   ARTICLE 12

                             Assignment or Sublease

     12.1 Tenant shall not,  directly or  indirectly,  without the prior written
consent of Landlord (which consent shall not be unreasonably  withheld),  assign
this Lease or any interest  herein or sublease the Premises or any part thereof,
or permit the use or  occupancy  of the  Premises by any person or entity  other
than Tenant;  provided,  however,  Landlord's  withholding  of consent  shall be
conclusively presumed reasonable if: (a) the financial condition of the proposed
transferee  is not  suitable  to perform  the  obligations  being  assumed by it
hereunder;  or  (b)  the  proposed  use  of the  Premises  (i) is not  permitted
hereunder  or under any Legal  Requirements,  or (ii) is other  than  office use
(except in the case of a sublease of the portions of the Premises to be used for
an  employee  cafeteria  and  child  care  center  to  the  operators  of  those
facilities).  This Lease shall not, nor shall any interest herein, be assignable
as to the  interest of Tenant  involuntarily  or by operation of law without the
prior written consent of Landlord.  Any of the foregoing acts without such prior
written  consent of Landlord shall be void and shall, at the option of Landlord,
constitute  a  default  that   entitles   Landlord  to  terminate   this  Lease.
Notwithstanding  the  foregoing,  Landlord  hereby  consents to any  sublease or
assignment to any direct or indirect wholly-owned subsidiary of either Tenant or
ICG Communications, Inc., a Delaware corporation or to any surviving corporation
resulting  from a  merger  with  Tenant,  or to any  corporation  as part of the
acquisition  of all or  substantially  all of the assets and  business of Tenant
(collectively,  a "Corporate  Successor"),  provided such sublease or assignment
otherwise complies with this Article 12, and provided further that Landlord does
not  approve any such  sublease or  assignment  in  connection  with a merger or
acquisition if the net worth or  creditworthiness  of such subtenant or assignee
is, in Landlord's  reasonable  judgment,  less than that of Tenant prior to such
merger or  acquisition  transaction.  Tenant agrees that the instrument by which
any  assignment or sublease to which  Landlord  consents is  accomplished  shall
expressly  provide  that the  assignee  or  subtenant  will  perform  all of the
covenants to be performed by Tenant under this Lease (in the case of a sublease,
only insofar as such covenants  relate to the portion of the Premises subject to
such  sublease) as and when  performance  is due after the effective date of the
assignment  or sublease  and that  Landlord  will have the right to enforce such
covenants directly against such assignee or subtenant.  Any purported assignment
or sublease without an instrument  containing the foregoing  provisions shall be
void.  Tenant  shall in all  cases  remain  liable  for the  performance  by any
assignee or subtenant of all such covenants.

     12.2 If Landlord  consents in writing,  Tenant may  complete  the  intended
assignment or sublease subject to the following covenants:  (a) no assignment or
sublease  shall be valid and no assignee or subtenant  shall take  possession of
the Premises or any part thereof  until an executed  duplicate  original of such
assignment or sublease,  in compliance  with section 12.1, has been delivered to
Landlord,  (b) no assignee or subtenant  shall have a right further to assign or
sublease.
<PAGE>
                                       21


     12.3 No  assignment  or  sublease  whatsoever  shall  release  Tenant  from
Tenant's  obligations  and  liabilities  under this  Lease or alter the  primary
liability  of Tenant to pay all rent and to perform all  obligations  to be paid
and  performed  by Tenant.  The  acceptance  of rent by Landlord  from any other
person or entity shall not be deemed to be a waiver by Landlord of any provision
of this Lease. Consent to one assignment or sublease shall not be deemed consent
to any  subsequent  assignment  or  sublease.  If  any  assignee,  subtenant  or
successor  of  Tenant  defaults  in  the  performance  of any  obligation  to be
performed by Tenant  under this Lease,  Landlord  may proceed  directly  against
Tenant  without the  necessity of  exhausting  remedies  against such  assignee,
subtenant  or  successor.  Landlord  may consent to  subsequent  assignments  or
subleases  or  amendments  or   modifications  to  this  Lease  with  assignees,
subtenants or successors of Tenant, without notifying Tenant or any successor of
Tenant and without obtaining any consent thereto from Tenant or any successor of
Tenant,  and such action  shall not release  Tenant  from  liability  under this
Lease.

     12.4 Upon  Tenant's  entering into any agreement to sell or transfer all or
substantially  all of its  assets  (whether  or not  the  assets  to be  sold or
transferred  include this Lease),  Tenant shall within three (3) days thereafter
notify  Landlord of the essential  terms of such  agreement.  If Tenant sells or
transfers  substantially  all of its assets but does not  expressly  assign this
Lease to the transferee,  then at Landlord's option,  this Lease shall be deemed
to have been assigned to such transferee and such transferee  shall be deemed to
have assumed all of Tenant's  obligations  under this Lease.  If such transferee
does not expressly assume such obligations in writing within ten (10) days after
demand  delivered to Tenant,  the  Stipulated  Difference (as defined in section
14.2(c)) shall be increased by five million dollars ($5,000,000).

                                Entry by Landlord

     13.1 Landlord  shall have the right,  upon not less than  twenty-four  (24)
hours prior notice (except in cases of emergency),  to enter the Premises at any
time to (a)  inspect the  Premises,  (b)  exhibit  the  Premises to  prospective
purchasers,  lenders  or  (during  the last  eighteen  (18)  months of the term)
tenants, (c) determine whether Tenant is performing all of Tenant's obligations,
(d) perform any  obligations of Tenant in accordance with section 14.5, (e) post
notices of nonresponsibility in and about the Premises,  (f) make any repairs to
the  Premises  and (g)  investigate  and  perform  tests to  determine  Tenant's

<PAGE>
                                       22


compliance  with Article 21. In connection  with any such entry,  Landlord shall
use reasonable  efforts to avoid any  unnecessary  disruption of or interference
with Tenant's business  operation.  Tenant waives all claims for damages for any
injury or inconvenience to or interference with Tenant's  business,  any loss of
occupancy or quiet  enjoyment of the  Premises or any other loss  occasioned  by
such entry.  If  Landlord  removes any  existing  underground  tanks and fueling
system from the Premises,  Landlord  shall have no obligation to replace them or
provide alternate tanks or a fueling system.  Landlord shall at all times have a
key to unlock  all such doors and  Landlord  shall have the right to use any and
all means which  Landlord  may deem proper to open such doors in an emergency to
obtain entry to the Premises.  Any entry to the Premises obtained by Landlord by
any of such means shall not under any circumstances be construed or deemed to be
a forcible or unlawful  entry into or a detainer of the Premises or an eviction,
actual or constructive, of Tenant from the Premises or any portion thereof.


                                   ARTICLE 14

                         Events of Default and Remedies

     14.1 The  occurrence of any one or more of the following  events ("Event of
Default") shall constitute a breach of this Lease by Tenant:

     (a) Tenant  fails to pay any Base Rent  within five (5) days after the date
when such rent becomes due or fails to make the additional  deposits to the Draw
Account within the time period set forth in section 24.5; or

     (b) Tenant  fails to pay any  additional  rent or other  amount of money or
charge payable by Tenant hereunder as and when such additional rent or amount or
charge becomes due and payable and such failure continues for more than ten (10)
Business Days after Landlord  gives written notice thereof to Tenant;  provided,
however, that after the second such failure in a calendar year, only the passage
of time,  but no further  notice,  shall be  required to  establish  an Event of
Default in the same calendar year; or

     (c) Tenant fails to perform or breaches any other  agreement or covenant of
this Lease to be  performed  or  observed by Tenant as and when  performance  or
observance  is due and such failure or breach  continues  for more than ten (10)
Business Days after Landlord  gives written notice thereof to Tenant;  provided,
however,  that if, by the nature of such agreement or covenant,  such failure or
breach cannot  reasonably be cured within such period of ten (10) Business Days,
an  Event of  Default  shall  not  exist as long as  Tenant  commences  with due
diligence  and dispatch the curing of such failure or breach within a reasonable
period of time after  becoming  aware of such  failure or breach and,  having so
commenced,  thereafter  prosecutes with diligence and dispatch and completes the
curing of such failure or breach within a reasonable time; or
<PAGE>
                                       23


     (d) Tenant or any Guarantor  (i) files,  or consents by answer or otherwise
to the  filing  against  it of, a  petition  for  relief  or  reorganization  or
arrangement  or any other  petition in bankruptcy or for  liquidation or to take
advantage of any  bankruptcy,  insolvency  or other  debtors'  relief law of any
jurisdiction,  (ii) makes an assignment for the benefit of its creditors,  (iii)
consents to the appointment of a custodian,  receiver,  trustee or other officer
with similar powers of Tenant (or any Guarantors) or of any substantial  part of
Tenant's (or any Guarantor's)  property, or (iv) takes action for the purpose of
any of the foregoing; or

     (e) Without  consent by Tenant or a Guarantor (as the case may be), a court
or government  authority  enters an order,  and such order is not vacated within
thirty (30) days, (i) appointing a custodian, receiver, trustee or other officer
with similar powers with respect to Tenant or any Guarantor,  or with respect to
any  substantial  part  of  Tenant's  or  any  Guarantor's   property,  or  (ii)
constituting  an order  for  relief  or  approving  a  petition  for  relief  or
reorganization  or  arrangement  or any  other  petition  in  bankruptcy  or for
liquidation or to take advantage of any bankruptcy, insolvency or other debtors'
relief law of any jurisdiction, or (iii) ordering the dissolution, winding-up or
liquidation of Tenant or any Guarantor; or

     (f) This Lease or any estate of Tenant  hereunder  is levied upon under any
attachment or execution and such  attachment or execution is not vacated  within
thirty (30) days; or

     (g) Tenant vacates or abandons the Premises; or

     (h) Any Lease  Guaranty  (as defined in section  24.1) ceases to be in full
force and effect; or

     (i) Tenant  merges or sells or transfers  all or  substantially  all of its
assets  (whether  or not the assets sold or  transferred  include  this  Lease),
unless Landlord consents to such transaction in accordance with section 12.1.

     14.2 If an Event of Default  occurs,  Landlord  shall have the right at any
time to give a written  termination  notice to Tenant and, on the date specified
in such notice,  Tenant's  right to  possession  shall  terminate and this Lease
shall terminate. Upon such termination, Landlord shall have the right to recover
from Tenant:

     (a) The worth at the time of award of all unpaid rent which had been earned
at the time of termination;

     (b) The worth at the time of award of the amount by which all  unpaid  rent
which would have been earned after  termination  until the time of award exceeds
the amount of such  rental loss that Tenant  proves  could have been  reasonably
avoided;
<PAGE>
                                       24


     (c) The worth at the time of award of the amount by which all  unpaid  rent
for the  balance of the term of this Lease  after the time of award  exceeds the
amount of such rental  loss that  Tenant  proves  could be  reasonably  avoided;
provided that, in the event that, at the time of the  termination of this Lease,
the Premises or any substantial  portion of the Premises have not been relet, in
lieu of such  amount,  Landlord  shall be entitled to withdraw  the balance then
held in the Draw Account and retain such balance as  liquidated  damages for the
loss of the rents  payable  under this Lease for the balance of the term of this
Lease, in which event such  liquidated  damages would be accepted by Landlord in
full satisfaction of all damages suffered by Landlord for the loss of rents that
would have been  payable  under the Lease with  respect to the period  after the
date of termination  of the Lease.  The amount of funds from time to time in the
Draw Account  pursuant to this Article 24 (subject to section  12.4) is referred
to herein as the "Stipulated Difference." Tenant and Landlord agree that (a) the
Stipulated  Difference is a fair and  reasonable  estimate of the  difference in
value of the Premises if Tenant's covenants and obligations, as tenant under the
Leases,  are performed in all material respects and the value of the Premises if
such covenants and obligations are not performed in all material  respects,  (b)
that the  definition  of the term  "Event  of  Default"  reflects  Tenant's  and
Landlord's  negotiated  agreement as to a fair standard for determining  whether
such covenants and obligations are being performed in all material respects, and
(c) that such difference in value will not be precisely calculable since it will
involve  complex  and  intangible  factors  such as  reduced  salability  of the
Premises,  reduced  creditworthiness of Landlord and harm to Landlord's business
reputation. Said liquidated damages would not be in lieu of or otherwise replace
amounts that Landlord would be entitled to collect under Sections  14.2(a),  (b)
and (d), and  Landlord  would be entitled to collect all of the same from Tenant
in addition to the liquidated damages provided for in this section 14.2(c); and

     (d)  All  other  amounts  necessary  to  compensate  Landlord  for  all the
detriment  proximately  caused by  Tenant's  failure to perform  all of Tenant's
obligations  under this Lease or which in the ordinary course of things would be
likely  to result  therefrom.  The  "worth at the time of award" of the  amounts
referred to in clauses (a) and (b) above shall be computed by allowing  interest
at the  Interest  Rate (as  defined in section  3.4).  The "worth at the time of
award" of the  amount  referred  to in clause  (c) above  shall be  computed  by
discounting such amount at the discount rate of the Federal Reserve Bank located
nearest the Premises at the time of award plus one percent (1%). For the purpose
of  determining  unpaid  rent under  clauses  (a),  (b) and (c) above,  the rent
reserved  in this Lease  shall be deemed to be the total rent  payable by Tenant
under Articles 3 and 5 hereof.

     14.3 If an Event of Default occurs,  Landlord may, without terminating this
Lease, terminate Tenant's right to possession of the Premises, in which event:
<PAGE>
                                       25


     (a) Landlord may, with or without process of law, retake  possession of the
Premises;

     (b) Tenant's  obligations under this Lease (including the obligation to pay
rent on the dates  specified in this Lease) shall  continue  unaffected  for the
entire term of this Lease or until such  earlier  time as  Landlord  may, at its
option,  elect to terminate this Lease which Landlord may, at its option,  do at
any time;

     (c) Without being deemed to have elected to terminate this Lease,  Landlord
may relet the  Premises  in  accordance  with  Section  14.4 for the  account of
Tenant,  in the name of  Landlord  or in the name of  Tenant  on such  terms and
conditions  and to such tenants as Landlord may, in its  discretion,  determine.
Landlord shall be entitled to remodel and repair the Premises,  to subdivide the
Premises,  or to combine all or any portion or  portions  of the  Premises  with
other premises in any manner which  Landlord shall deem  appropriate in order to
accomplish such reletting;  and Tenant shall reimburse Landlord,  on demand, for
all  costs and  expenses  in  connection  with such  repair  or  remodeling  and
reletting ("Reletting Costs"). Notwithstanding Landlord's recovery of possession
and  notwithstanding  any  reletting,  Tenant  shall  continue  to pay all  rent
provided for herein as and when it comes due, less the net proceeds  received by
Landlord from any reletting;  provided that, if the proceeds of reletting exceed
the amount due from  Tenant,  on or before the 15th day of each month,  Landlord
shall refund to Tenant any amount by which the rent paid by Tenant  through such
date,  when added to the  amount,  if any,  recovered  by  Landlord  through any
reletting of the Premises through such date,  reduced by all Reletting Costs for
which  Tenant has not paid  Landlord,  and reduced by all amounts  Landlord  has
previously  refunded  to Tenant  under this  subsection,  and  reduced any other
amounts Tenant owes Landlord  under this Lease,  exceeds the rent due under this
Lease  through such date.  Tenant shall  reimburse  Landlord upon demand for all
Reletting  Costs and any other costs and  expenses  which  Landlord may incur in
connection with recovery of possession or repair of the Premises;

     (d) In the event Landlord proceeds under this Section 14.3, Landlord may at
any time terminate this Lease by notice to Tenant.  Such termination  shall have
the effect  specified  in Section  14.2 and  Landlord  shall be  entitled to all
remedies under Section 14.2 upon termination.

     14.4  Landlord  shall have no duty to attempt to  mitigate  its  damages by
retaking  and  reletting  the  Premises;  provided  that,  if  Landlord  retakes
possession of the Premises under either  Section 14.2 or Section 14.3,  Landlord
shall use good faith  reasonable  efforts to relet the Premises,  subject to the
following terms, conditions and limitations:
<PAGE>
                                       26


     (a) Any  reletting  of the  Premises  shall be on the terms and  conditions
determined  by  Landlord in its  reasonable  good faith  discretion  and to such
tenants as  Landlord  shall  approve in its  reasonable  good faith  discretion.
Without limiting the generality of the foregoing,  Tenant  acknowledges that, in
reletting the  Premises,  Landlord may  legitimately  consider the effect of any
such  reletting on the Premises and on any other  property  owned by Landlord or
any other person or entity  controlling,  controlled by, or under common control
with Landlord, or otherwise affiliated with Landlord (which parties are referred
to herein collectively as "Landlord Affiliates"), and, therefore, may decide not
to lease the  Premises  at rates  which are lower  than  Landlord  is  otherwise
endeavoring  to maintain in the  Premises,  or at rates which are lower than the
rate that Landlord believes to be appropriate for the Premises.

     (b) Tenant recognizes that Landlord and Landlord's Affiliates currently and
in the future may have vacant space in the  Premises and other  property and may
in the future also have vacant  space in new  projects in  competition  with the
Premises. In no event shall Landlord be obligated to use any effort to relet the
Premises in preference to leasing any such other vacant space then available for
leasing by  landlord  or any of  Landlord's  Affiliates.  Landlord  shall not be
deemed to have  failed to mitigate  damages  solely on account of the leasing of
other space which Landlord or Landlord's  Affiliates  have available  instead of
the reletting of the Premises.

     14.5 Whether or not Landlord  elects to terminate  this Lease on account of
any Event of Default by Tenant,  and  subject to  Landlord's  duty to attempt to
mitigate  its  damages  as  provided  herein,  Landlord  shall have the right to
terminate  any and all  subleases,  licenses,  concessions  or other  consensual
arrangements for possession entered into by Tenant and affecting the Premises or
may,  in  Landlord's  sole  discretion,  succeed to  Tenant's  interest  in such
sublease,  licenses,  concessions  or  arrangements.  In the event of Landlord's
election  to succeed  to  Tenant's  interest  in any such  subleases,  licenses,
concessions or arrangements,  Tenant shall, as of the date of notice by Landlord
of such  election,  have no further  right to or  interest  in the rent or other
consideration  receivable  thereunder,  except that amounts actually received by
Landlord  thereunder  shall be credited  against  any amounts  payable by Tenant
hereunder.

     14.6 Except as otherwise provided in section 14.2(c), the remedies provided
for in this Lease are in addition to all other remedies available to Landlord at
law or in equity by statute or otherwise.

     14.7 All  agreements  and  covenants  to be performed or observed by Tenant
under this Lease  shall be at  Tenant's  sole cost and  expense  and without any
abatement of rent.  If Tenant fails to pay any sum of money to be paid by Tenant
or to perform any other act to be performed by Tenant under this Lease, Landlord
shall  have the  right,  but shall not be  obligated,  and  without  waiving  or
releasing Tenant from any obligations of Tenant,  to make any such payment or to
perform  any such other act on behalf of Tenant in  accordance  with this Lease.
All sums so paid by Landlord and all necessary  incidental costs shall be deemed
additional  rent hereunder and shall be payable by Tenant to Landlord on demand,
together with interest on all such sums from the date of expenditure by Landlord
to the date of repayment by Tenant at the Interest Rate. Landlord shall have, in
addition  to all other  rights and  remedies  of  Landlord,  the same rights and
remedies in the event of the  nonpayment of such sums plus interest by Tenant as
in the case of default by Tenant in the payment of rent.

     14.8 If Tenant  abandons or surrenders the Premises,  or is dispossessed by
process of law or otherwise, any movable furniture, equipment, trade fixtures or
personal  property  belonging to Tenant and left in the Premises shall be deemed
to be abandoned, at the option of Landlord, and Landlord shall have the right to
sell  or  otherwise  dispose  of  such  personal  property  in any  commercially
reasonable manner.

                              Damage or Destruction

     15.1 If the  Premises,  or any part  thereof,  is  damaged by fire or other
casualty before the Commencement  Date or during the term of this Lease,  Tenant
shall repair such damage and restore the Premises to  substantially  the same or
better  condition  as  existed  before  the  occurrence  of such  fire or  other
casualty, Tenant shall repair and replace all such movable furniture, equipment,
trade fixtures and personal property,  and this Lease shall remain in full force
and effect.  Such repair and  replacement  by Tenant shall be done in accordance
with  Article 9. In no event shall rent abate.  Provided  that Tenant shall have
unconditionally  ratified  in writing  its repair  and  restoration  obligations
pursuant to this section 15.1 with respect to such  casualty,  Tenant shall have
the right to participate  in the adjustment of any insurance  claim arising from
such casualty and shall have the right to approve any  settlement or adjustment,
which approval shall not unreasonably be withheld or delayed. Provided Tenant is
not in  default  under this Lease  (and no event has  occurred  which,  with the
passage of time, the giving of notice, or both, would constitute a default), and
provided  Tenant has (i) delivered to Landlord  plans and  specifications  and a
budget  for such  repair  and  restoration  (all of which  Landlord  shall  have
approved in its reasonable  judgment),  and (ii) deposited with Landlord cash in
the sum  equal to the  excess,  if any,  of the  total  cost  set  forth in such
approved  budget over the amount of  insurance  proceeds  received on account of
such  casualty,  then  Landlord  shall make  available  to Tenant all  insurance
proceeds  actually  received  by  Landlord  on  account  of such  casualty,  for
application to the costs of such approved repair and restoration, as follows:

     (a) No more  frequently  than once per calendar  month,  Tenant may request
that Landlord reimburse Tenant for costs incurred by Tenant for work in place to
repair and restore the Premises during the immediately preceding calendar month.
Tenant's  request  shall  certify  that  all  work for  which  reimbursement  is
requested was performed in compliance with the plans and specifications approved
by Landlord  pursuant to Article 9 and all  applicable  laws,  and shall include
reasonably   satisfactory   evidence  of  the  costs   incurred  by  Tenant  and
unconditional  lien  releases in form and substance  required by applicable  law
executed by all mechanic's, materialmen, laborers, suppliers and contractors who
performed any portion of the repair work or supplied materials.

     (b) Within fifteen (15) days after  receiving  Tenant's  request,  Landlord
shall  approve or  disapprove  Tenant's  request,  which  approval  shall not be
unreasonably  withheld, by written notice to Tenant. If Landlord approves all or
any  portion  of a  request  and  Landlord  has  received  (and  not  previously
disbursed) insurance proceeds, then Landlord's approval shall include a check in
the amount approved by Landlord. If Landlord disapproves all or any portion of a
request,  then Landlord's  notice shall state the reasons for that  disapproval.
Landlord's failure to deliver a notice approving or disapproving a request shall
be  conclusively  deemed  Landlord's  disapproval  of the request.  In addition,
Landlord shall have the right to impose other  conditions  upon  disbursement so
long as they  are  consistent  with  customary  construction  loan  disbursement
practices.  Landlord shall maintain in an interest-bearing  account any proceeds
of insurance  held by Landlord and any sums  deposited  with  Landlord by Tenant
pursuant to this  section  15.1,  and so long as no default by Tenant under this
Lease has occurred, interest earned on such account shall be disbursed to Tenant
upon  completion  of such  repair and  restoration,  except to the  extent  such
interest has been applied to the costs of such repair and restoration.

     15.2 If the  Premises,  or any part  thereof,  is  damaged by fire or other
casualty and (a) such fire or other casualty  occurs during the last twelve (12)
months  of the term of this  Lease and the  repair  and  restoration  work to be
performed  by Tenant in  accordance  with section  15.1  cannot,  as  reasonably
estimated by Landlord,  be completed within four (4) months after the occurrence
of such  fire or other  casualty,  or (b) the  insurance  proceeds  received  by
Landlord and Tenant in respect of such damage are not adequate to pay the entire
cost, as reasonably estimated by Landlord, of the repair and restoration work to
be  performed  by Landlord in  accordance  with section 15.1 and Tenant does not
deposit such shortfall with  Landlord,  then, in any such event,  Landlord shall
have the right,  by giving written notice to Tenant within sixty (60) days after
the occurrence of such fire or other casualty, to terminate this Lease as of the
date of such  notice,  in which case all  insurance  proceeds on account of such
casualty  shall be paid to Landlord.  If Landlord does not exercise the right to
terminate this Lease in accordance  with this section 15.2,  Tenant shall repair
such damage and restore the  Premises in  accordance  with section 15.1 and this
Lease shall remain in full force and effect.

                                 Eminent Domain

     16.1 If a  substantial  portion of the Premises is taken and the  remaining
portion of the Premises is not reasonably suitable for Tenant's purposes,  or if
a portion of the Premises is taken resulting in a substantial  loss of access to
and from the Premises  without  reasonable  substitute  access being  available,
Landlord and Tenant each shall have the right,  by giving  written notice to the
other within thirty (30) days after the date of such taking,  to terminate  this
Lease. If either Landlord or Tenant exercises such right to terminate this Lease
in accordance  with this section 16.1, this Lease shall terminate as of the date
of such taking. If neither Landlord nor Tenant exercises such right to terminate
this Lease in accordance  with this section 16.1,  this Lease shall terminate as
to the portion of the  Premises so taken as of the date of such taking and shall
remain in full force and effect as to the portion of the  Premises not so taken,
Tenant shall  restore the portion of the Premises not so taken to an  integrated
architectural  unit in  accordance  with  Article 9 and the Base  Rent  shall be
reduced as of the date of such taking in the  proportion  that the rentable area
of the Premises so taken bears to the total  rentable area of the  Premises.  If
all of the Premises is taken by exercise of the power of eminent  domain  before
the  Commencement  Date or  during  the term of this  Lease,  this  Lease  shall
terminate as of the date of such taking.

     16.2 If all or any part of the  Premises  is taken by exercise of the power
of eminent domain, all awards, compensation,  damages, income, rent and interest
payable in connection  with such taking shall,  except as expressly set forth in
this section  16.2,  be paid to and become the property of Landlord,  and Tenant
hereby assigns to Landlord all of the foregoing. Without limiting the generality
of the  foregoing,  Tenant  shall have no claim  against  Landlord or the entity
exercising  the power of eminent  domain for the value of the  leasehold  estate
created by this Lease or any unexpired term of this Lease. Tenant shall have the
right to claim and  receive  directly  from the entity  exercising  the power of
eminent domain only the share of any award  determined to be owing to Tenant for
the taking of improvements  installed in the portion of the Premises so taken by
Tenant at Tenant's sole cost and expense based on the unamortized  cost actually
paid by  Tenant  for such  improvements,  for the  taking  of  Tenant's  movable
furniture,  equipment,  trade  fixtures  and  personal  property,  for  loss  of
goodwill,  for interference  with or interruption of Tenant's  business,  or for
removal and relocation expenses.

     16.3 In the event of any taking other than a taking  referred to in section
16.1, this Lease shall continue in full force and effect,  Tenant shall continue
to pay  all of the  rent  and to  perform  all of the  covenants  of  Tenant  in
accordance  with  this  Lease  and  Tenant  shall  restore  the  Premises  to an
integrated  architectural  unit in accordance with Article 9. Provided Tenant is
not in  default  under this Lease  (and no event has  occurred  which,  with the
passage of time, the giving of notice, or both, would constitute a default), and
provided  Tenant has (i) delivered to Landlord  plans and  specifications  and a
budget  for such  repair  and  restoration  (all of which  Landlord  shall  have
approved in its reasonable  judgment),  and (ii) deposited with Landlord cash in
the sum  equal to the  excess,  if any,  of the  total  cost  set  forth in such
approved  budget  over the amount of  condemnation  award  proceeds  received on
account  of such  taking,  then  Landlord  shall  make  available  to Tenant all
condemnation  award  proceeds  actually  received by Landlord on account of such
taking, for application to the costs of such approved repair and restoration, as
follows:
<PAGE>
                                       31


     (a) No more  frequently  than once per calendar  month,  Tenant may request
that Landlord reimburse Tenant for costs incurred by Tenant for work in place to
repair and restore the Premises during the immediately preceding calendar month.
Tenant's  request  shall  certify  that  all  work for  which  reimbursement  is
requested was performed in compliance with the plans and specifications approved
by Landlord  pursuant to Article 9 and all  applicable  laws,  and shall include
reasonably   satisfactory   evidence  of  the  costs   incurred  by  Tenant  and
unconditional  lien  releases in form and substance  required by applicable  law
executed by all mechanic's, materialmen, laborers, suppliers and contractors who
performed any portion of the repair work or supplied materials.

     (b) Within fifteen (15) days after  receiving  Tenant's  request,  Landlord
shall  approve or  disapprove  Tenant's  request,  which  approval  shall not be
unreasonably  withheld, by written notice to Tenant. If Landlord approves all or
any  portion  of a  request  and  Landlord  has  received  (and  not  previously
disbursed) condemnation award proceeds, then Landlord's approval shall include a
check in the amount  approved by Landlord.  If Landlord  disapproves  all or any
portion of a request,  then  Landlord's  notice shall state the reasons for that
disapproval.  Landlord's failure to deliver a notice approving or disapproving a
request shall be conclusively  deemed Landlord's  disapproval of the request. In
addition,  Landlord  shall  have  the  right to  impose  other  conditions  upon
disbursement  so long as they are consistent  with customary  construction  loan
disbursement practices.  Landlord shall maintain in an interest-bearing  account
any condemnation  award held by Landlord and any sums deposited with Landlord by
Tenant  pursuant to this section 16.3, and so long as no default by Tenant under
this Lease has occurred,  interest  earned on such account shall be disbursed to
Tenant upon completion of such repair and restoration, except to the extent such
interest has been applied to the costs of such repair and restoration.

     16.4 As used in this Article 16, a "taking" means the acquisition of all or
part of the Premises for a public use by exercise of the power of eminent domain
(or a sale of any or all of the Premises in lieu, or under threat,  thereof) and
the taking shall be  considered  to occur as of the earlier of the date on which
possession of the Premises (or part so taken) by the entity exercising the power
of eminent domain is authorized as stated in an order for possession or the date
on which title to the Premises (or part so taken) vests in the entity exercising
the power of eminent domain.

                         Subordination, Merger and Sale

     17.1 This Lease shall be subject and  subordinate  at all times to the lien
of all mortgages and deeds of trust  securing any amount or amounts  whatsoever,
and any ground  lease or master  lease of the  Premises,  which may now exist or
hereafter  be placed on or against  the  Premises  or on or  against  Landlord's
interest  or estate  therein,  all  without  the  necessity  of  having  further
instruments executed by Tenant to effect such subordination. Notwithstanding the
foregoing,  in the event of a foreclosure  of any such mortgage or deed of trust
or of any other action or proceeding for the enforcement thereof, or of any sale
thereunder, or in the event any such ground lease or master lease is terminated,
this Lease shall not be  terminated  or  extinguished,  nor shall the rights and
possession of Tenant hereunder be disturbed,  if no Event of Default then exists
under this Lease, and Tenant shall attorn to the person who acquires  Landlord's
interest hereunder through any such mortgage or deed of trust.  Tenant agrees to
execute, acknowledge and deliver upon demand such further instruments evidencing
such  subordination of this Lease to the lien of all such mortgages and deeds of
trust or to all such  ground  leases or master  leases  of the  Premises  as may
reasonably be required by Landlord,  but Tenant's  covenant to subordinate  this
Lease to  mortgages  or deeds of  trust,  or ground  leases  or  master  leases,
hereafter  executed is  conditioned  upon each such  senior  mortgage or deed of
trust, or ground lease or master lease, or a separate  subordination  agreement,
containing the commitments specified in the preceding sentence. Without limiting
the  generality of the foregoing,  Tenant agrees to enter into a  subordination,
nondisturbance  and  attornment  agreement in the form required by the holder of
any such  mortgage or deed of trust or by any party to any such ground  lease or
master lease.

     17.2 The voluntary or other surrender of this Lease by Tenant,  or a mutual
cancellation  thereof,  shall  not work a merger  and  shall,  at the  option of
Landlord,  terminate all or any existing subleases or subtenancies or operate as
an assignment to Landlord of any or all such subleases or subtenancies.

     17.3 If the original  Landlord  hereunder,  or any  successor  owner of the
Premises,  sells or conveys the Premises, all liabilities and obligations on the
part of the  original  Landlord,  or such  successor  owner,  under  this  Lease
accruing  after  such  sale or  conveyance  shall  terminate  and  the  original
Landlord,  or such successor owner, shall  automatically be released  therefrom,
and thereupon all such liabilities and obligations shall be binding upon the new
owner. Tenant agrees to attorn to such new owner.

days after  written  request by Landlord,  execute,  acknowledge  and deliver to
Landlord a certificate, in the form attached as Exhibit A, or such other form as
may be  requested,  certifying:  (a) that this Lease is  unmodified  and in full
force and effect  (or, if there have been  modifications,  that this Lease is in
full  force and  effect as  modified,  and  stating  the date and nature of each
modification);  (b) the Commencement  Date and the Expiration Date determined in
accordance with Article 2 and the date, if any, to which all rent and other sums
payable hereunder have been paid; (c) that no notice has been received by Tenant
of any  default  by  Tenant  hereunder  which has not been  cured,  except as to
defaults  specified  in such  certificate;  (d) that  Landlord is not in default
under this Lease,  except as to defaults specified in such certificate;  and (e)
such other matters as may be  reasonably  requested by Landlord or any actual or
prospective  purchaser or mortgage  lender.  Any such  certificate may be relied
upon by Landlord and any actual or prospective  purchaser or mortgage  lender of
the Premises or any part thereof.

     (b) At any time and from time to time, Landlord shall, within ten (10) days
after written  request by Tenant,  execute,  acknowledge and deliver to Tenant a
certificate certifying:  (a) that this Lease is unmodified and in full force and
effect (or, if there have been  modifications,  that this Lease is in full force
and effect as modified,  and stating the date and nature of each  modification);
(b) the Commencement  Date and the Expiration Date determined in accordance with
Article  2 and the  date,  if any,  to which  all rent and  other  sums  payable
hereunder  have been paid;  (c) that no notice has been  received by Landlord of
any  default  by  Landlord  hereunder  which  has not been  cured,  except as to
defaults specified in such certificate;  (d) that Tenant is not in default under
this Lease,  except as to defaults  specified in such certificate;  and (e) such
other matters as may be reasonably requested by Tenant. Any such certificate may
be relied upon by Tenant and any actual or prospective lender.

     19.1 If,  without  objection by Landlord,  Tenant holds  possession  of the
Premises  after  expiration  of the term of this Lease,  Tenant  shall  become a
tenant from month to month upon the terms  herein  specified  but at a Base Rent
equal to one  hundred  twenty  percent  (120%) of the Base Rent in effect at the
expiration  of the term of this Lease  pursuant to Article 3, payable in advance

Statements")  for the fiscal  year of ICGC ended on the  previous  December  31,

                               Hazardous Materials

     21.1 As used herein,  the term "Hazardous  Material" means any hazardous or
toxic substance, material or waste, or any pollutant or contaminant, or words of
similar  import,  which  is or  becomes  regulated  by  any  local  governmental
authority,  the state in which the Premises are  located,  or the United  States
Government.  The term "Hazardous Material" includes,  but is not limited to, any
material  or  substance  which is, (i)  designated  as a  "hazardous  substance"
pursuant to section 311 of the Federal  Water  Pollution  Control Act (33 U.S.C.

Material (other than normal  quantities of office supplies and cleaning supplies
which Tenant shall  handle,  use,  store and dispose of in  compliance  with all
Environmental  Requirements) without prior written notice to Landlord.  Any such
notice by Tenant to Landlord  shall be in writing and shall  demonstrate  to the
reasonable satisfaction of Landlord that such Hazardous Material is necessary to
the business of Tenant and will be handled, used, generated,  treated, stored or
disposed of in a manner that complies with all Environmental  Requirements.  Any
such handling, use, generation,  treatment, storage or disposal of any Hazardous

(a) actual or alleged violation of Environmental  Requirements by Tenant or with
respect  to the  Premises,  (b)  actual or  threatened  migration  of  Hazardous
Material from the Premises,  or (c) the existence of Hazardous Material in or on
the  Premises or  regarding  any actual or  threatened  investigation,  inquiry,
lawsuit, claim, citation,  directive,  summons,  proceeding,  complaint, notice,

     21.5 Tenant shall indemnify and defend  Landlord  against and hold Landlord
harmless from all claims, demands,  liabilities,  damages, fines,  encumbrances,
liens,  losses,  costs and expenses,  including  reasonable  attorneys' fees and
disbursements, and costs and expenses of investigation,  arising from or related
to the existence on or after the Commencement  Date of Hazardous  Material in or
on  the  Premises  or  the  actual  or  threatened  migration  on or  after  the
Commencement Date of Hazardous Material from the Premises or the existence on or
after the  Commencement  Date of a violation of  Environmental  Requirements  by
Tenant or with respect to the  Premises.  The  obligations  of Tenant under this
section  21.5  shall not be  affected  by any  investigation  by or on behalf of
Landlord or by any  information  which  Landlord may have or obtain with respect
thereto. Tenant shall, to the reasonable  satisfaction of Landlord,  perform all
remedial  actions  necessary  to  remove  any  Hazardous  Material  in or on the
Premises on or after the  Commencement  Date or to remedy  actual or  threatened
migration from the Premises of any Hazardous Material or to remedy any actual or
threatened  violation of  Environmental  Requirements,  provided  such  remedial
action is required  under  Environmental  Requirements.  This section 21.5 shall

                                     Waiver

     22.1 The waiver by Landlord or Tenant of any breach of any covenant in this
Lease shall not be deemed to be a waiver of any subsequent breach of the same or
any other  covenant  in this Lease,  nor shall any custom or practice  which may
grow up  between  Landlord  and  Tenant in the  administration  of this Lease be
construed  to waive or to lessen the right of  Landlord or Tenant to insist upon
the performance by Landlord or Tenant in strict  accordance with this Lease. The
subsequent  acceptance  of rent  hereunder by Landlord or the payment of rent by
Tenant  shall not waive any  preceding  breach by Tenant of any covenant in this
Lease, nor cure any Event of Default,  nor waive any forfeiture of this Lease or
unlawful detainer action, other than the failure of Tenant to pay the particular
rent so  accepted,  regardless  of  Landlord's  or  Tenant's  knowledge  of such
preceding breach at the time of acceptance or payment of such rent.

of this Lease and the  Commencement  Date,  on or before the  Commencement  Date
Tenant shall cause to be delivered to Landlord  Continuing  Lease  Guaranties in

     24.2 As a condition  precedent for Landlord's  benefit to the effectiveness
of this Lease and the  Commencement  Date,  on or before the  Commencement  Date
Tenant shall  deposit with  Landlord by wire  transfer the amount of ten million
dollars  ($10,000,000)  (the  "Security  Amount")  to be held by  Landlord  as a
security  deposit in accordance  with this Article 24. The Security Amount shall
be held in an  interest-bearing  account in Landlord's own name as secured party
with  respect  to the  security  interest  hereby  granted  by  Tenant,  as cash
collateral  (the  "Draw  Account"),  established  with a  financial  institution
selected by Landlord and reasonably  satisfactory  to Tenant.  Funds in the Draw
Account  shall  be  invested  in  such  Permitted  Investments  (as  hereinafter
defined),  as  Tenant  may from  time to time  designate  by  written  notice to
Landlord  and as approved by Landlord  in its  reasonable  discretion.  The term
"Permitted  Investments"  means money market  accounts with, or  certificates of
deposit issued by, a national bank or other depository institution which bank or
institution is  satisfactory to Landlord in its sole  discretion;  United States
Treasury  securities;  or  commercial  paper rated AAA or better by Standard and
Poors Corporation (or equivalent rating of another nationally  recognized credit
rating  agency).  Risk of loss of the amounts held in the Draw Account  shall be
borne  by  Tenant,  and  Landlord  shall  have no  liability  for any  loss,  or
diminution  in  value,  of the Draw  Account  due to any  failure  of,  or other
financial problems affecting, such financial institution. Interest earned on the
Draw Account  shall for all purposes  become part of the Draw  Account.  On each
anniversary  of the date the funds are  deposited in the Draw  Account,  amounts
held in the Draw Account in excess of the Security  Amount (as the same may have
been  adjusted  pursuant to section  24.6) shall be  disbursed  as follows:  (a)
first,  to pay all reasonable  costs to establish and maintain the Draw Account;
and (b) second, the balance, if any, to Tenant. Tenant hereby grants to Landlord
a security  interest in the Draw Account and all proceeds  thereof to secure the
full and  timely  performance  of  Tenant's  obligations  under this  Lease.  In
addition to the remedies set forth in this Lease, Landlord shall have all of the
rights  and  remedies  of a secured  party  pursuant  to the  [Colorado  Uniform
Commercial Code]. On or prior to the Commencement Date, Tenant shall execute and
deliver to Landlord such security  agreements,  financing  statements  and other
documents as Landlord  may  reasonably  require to further  evidence and perfect
such security interest.

     24.3 If this Lease is  terminated  and  Landlord is entitled to  liquidated
damages in  accordance  with section  14.2(c),  Landlord may withdraw all of the
funds then remaining in the Draw Account and retain the withdrawn amount.

     24.4 Landlord may, from time to time,  withdraw funds from the Draw Account
for application  against any installment of Rent not paid when due or to pay any
other amount payable by Tenant  hereunder  that is not paid when due,  including
amounts  payable by Tenant  under this Lease to  reimburse  Landlord for amounts
paid by Landlord for the account of Tenant as provided for in this Lease.

     24.5 In the event of a partial withdrawal of funds from the Draw Account in
accordance with section 24.4, Tenant shall,  within five (5) business days after
Landlord has given Tenant notice of such  withdrawal  (including  the purpose of
such withdrawal),  deposit to the Draw Account such additional funds as shall be
necessary to cause the amount of funds in the Draw Account to be returned to the
Security Amount and if Tenant fails to do so within that 5-day period,  an Event
of Default shall be deemed to have occurred and the Landlord may terminate  this
Lease and/or exercise any of its other rights and remedies, including its rights
under this Article 24.

     24.6 The Security  Amount shall be subject to  adjustment  on the terms and
conditions  set  forth  in this  section  24.6.  As of  April  15 of  each  year
commencing  with April 15, 2001 (each a "Reduction  Date"),  the Security Amount
shall be reduced by the Reduction  Amount (as defined below)  applicable to such
Reduction  Date,  provided that, as of such Reduction Date, all of the following

          immediately  preceding three fiscal years shall have been more than an

     24.7 (a) The  Security  Amount  shall be  reduced to five  million  dollars
($5,000,000)   at  any  time  that  Tenant   delivers  to  Landlord   reasonably

     continuous  period  of not  less  than  twelve  (12)  months  (without  any
     "CreditWatch" or downgrade consideration), ratings of its unsecured debt of

     its  unsecured  debt of BBB- or better from Duff & Phelps Credit Rating Co.
     ("Duff");

provided  that,  as of the date Tenant would be entitled to such  reduction,  no

reduction,  Landlord  shall  deliver to Tenant  from the Draw  Account an amount
equal to the excess (if any) of the funds then held in the Draw Account over the
adjusted Security Amount becoming effective upon such reduction. If the Security
Amount is less than five million  dollars  ($5,000,000),  this  section  24.7(a)
shall have no effect.

          (b)  Tenant's  obligations  pursuant  to this  Article  24 to  provide
     security  shall  terminate,  and Landlord  shall return to Tenant all funds
     remaining in the Draw Account at any time that Tenant  delivers to Landlord
     reasonably satisfactory evidence that:

               (i) either Tenant or ICGC shall have obtained, and maintained for
          a continuous period of not less than eighteen (18) months (without any
          "CreditWatch"  or downgrade  consideration),  ratings of its unsecured
          debt of BBB or better from S&P and Baa2 or better from Moody's; or

          for a continuous  period of not less than thirty (30) months  (without
          any  "CreditWatch"  or  downgrade  consideration),  a  rating  of  its
          unsecured  debt of BBB- or  better  from  S&P or Baa3 or  better  from

provided that, as of the time that Tenant  delivers to Landlord such evidence of
such ratings, no Event of Default has occurred and is continuing.

     24.8 Upon the  expiration  or sooner  termination  of this Lease,  Landlord
shall return to Tenant any funds  remaining in the Draw  Account,  provided that
Landlord  shall  have the  right to  retain  in the Draw  Account  (and  draw in
accordance with this Article 24) an amount which Landlord reasonably  determines
to be equal to the  damages  Landlord  has  suffered  arising  from any  uncured
default by Tenant.

     24.9 So long as no Event of Default has occurred and is continuing,  Tenant
shall have the right to provide Landlord,  in lieu of the security  described in
this Article 24, an  irrevocable  standby  letter of credit in the amount of the
Security Amount, in form and substance  satisfactory to Landlord and issued by a
bank satisfactory to Landlord (a "Letter of Credit"). In the event Tenant elects
to so provide a Letter of Credit,  Landlord and Tenant  shall  negotiate in good
faith an  amendment  to this Lease to set forth the rights  and  obligations  of
Landlord  and Tenant  with  respect to the Letter of Credit,  the terms of which
amendment  shall  provide  Landlord  with  comparable  security,  in  Landlord's
reasonable judgment, to that provided pursuant to this Article 24.

                                   ARTICLE 26

                          Option to Expand the Building

     26.1 (a) Upon and subject to the terms and  conditions  of this Article 26,
Landlord hereby grants to Tenant the right and option (the  "Expansion  Option")
(i) to request that Landlord  construct the Expansion  Improvements  (as defined
below)  and lease the  Expansion  Improvements  to  Tenant  in  accordance  with
Sections  26.2 and 26.4,  or (ii) to request that Landlord  purchase  from,  and
lease back to, Tenant the  Expansion  Improvements  upon  Tenant's  construction
thereof in accordance with Sections 26.3 and 26.4, or (iii) if Landlord declines
to  construct  or  purchase  from  Tenant  the  Expansion  Improvements,  to (A)
subdivide  the  Premises  and  purchase the portion of the Premises on which the
Expansion  Improvements  are  to be  constructed  and  construct  the  Expansion
Improvements  itself in  accordance  with Section  26.5,  or (B)  construct  the
Expansion  Premises itself as a leasehold  improvement  without  subdividing the
Premises in accordance with Section 26.6.

     (b) The additional  improvements to be constructed if the Expansion  Option
is exercised (the "Expansion  Improvements")  shall (i) be one or more buildings
separate from the existing  Building,  of design,  nature and type substantially
similar  to the  existing  Building,  and (ii) be of a size and be  located  and
configured  per the  location and  configuration  of "Phase 2" shown in the Site
Plan  attached  hereto as  Exhibit  C,  unless  at the  request  of the  Tenant,
Landlord, in its sole and absolute discretion, shall agree to construct or allow
Tenant to construct  Expansion  Improvements  of a different  design,  nature or
type.  Landlord  shall  have the  right,  but not the  obligation,  to provide a
proposal to construct the Expansion Improvements.

     (c) The  Expansion  Option  shall be  exercised  by Tenant,  if at all,  by
written  notice  thereof (an  "Expansion  Notice") to Landlord given not earlier
than the  Commencement  Date and not later than the tenth (10th)  anniversary of
the Commencement Date (the "Exercise Period").  The Expansion Notice may propose
either one or two buildings and shall be accompanied  by preliminary  conceptual
plans and specifications for the Expansion  Improvements  ("Preliminary Plans").
The Expansion  Notice shall specify whether Tenant (1) proposes to construct the
<PAGE>
                                       45



Expansion Improvements itself and requests that Landlord purchase and lease back
the Expansion  Improvements  in  accordance  with Sections 26.3 and 26.4, or (2)
requests that Landlord  construct the Expansion  Improvements  and lease them to
Tenant in accordance  with Sections 26.2 and 26.4.  The Expansion  Option may be
exercised  from time to time,  each  exercise  relating  to a single  additional
building.  No purported  exercise of the Expansion Option which fails to satisfy
the  conditions  set forth in Section 26.7 and no valid  exercise which is later
rescinded  shall impair  Tenant's  right  thereafter  to exercise the  Expansion
Option during the Exercise  Period.  As of the end of the Exercise  Period,  the
Expansion  Option shall lapse and be of no further  force and effect,  except to
the extent theretofore exercised. Time is of the essence of this provision.

     26.2  If  the  Expansion  Notice  requests  that  Landlord  constructs  the
Expansion  Improvements,  then not later than sixty (60) days after  delivery of
the Expansion Notice, Landlord shall notify Tenant if it elects not to construct
the  Expansion   Improvements  (which  election  shall  be  in  Landlord's  sole
discretion),  or, in the event  Landlord  proposes to  construct  the  Expansion
Improvements,  Landlord  shall  submit  to Tenant a notice  (the  "Specification
Notice") which notice shall contain  Landlord's  best good faith estimate of (i)
the total costs (hard and soft) of constructing the Expansion Improvements, (ii)
the  projected  date for  completion  and  delivery  to Tenant of the  Expansion
Improvements,  and (iii) the projected Expansion Base Rent. Tenant may elect, by
written notice to Landlord within sixty (60) days following  Tenant's receipt of
the Specification Notice, either to accept the terms of the Specification Notice
or to rescind its exercise of the Expansion  Option. In the event Landlord shall
have  notified  Tenant  that  Landlord  elects not to  construct  the  Expansion
Improvements,  then Tenant may elect, by written notice to Landlord within sixty
(60) days following Tenant's receipt of Landlord's notice, to either (A) rescind
its exercise of the  Expansion  Option,  (B) exercise the right (the  "Leasehold
Improvement Option") to construct the Expansion  Improvements on the Premises at
its sole cost in  accordance  with Section  26.6, or (C) exercise the right (the
"Tenant  Subdivision  Option") to cause the Premises to be subdivided  such that
the site on which the proposed Expansion Improvements are to be constructed (the
"Expansion  Site") is a separate legal parcel in compliance  with all applicable
laws,  codes,  ordinances and regulations  and with the  requirements of Section
26.5 and to  purchase  the  Expansion  Site  from  Landlord  and  construct  the
Expansion  Improvements  itself, all in accordance with Section 26.5;  provided,
however,  that if Tenant elects to either  rescind the exercise of the Expansion
Option or to exercise the Tenant Subdivision Option or the Leasehold Improvement
Option,  Tenant shall pay to Landlord as additional rent an amount equal to 150%
of Landlord's out-of-pocket costs incurred to third parties (including,  without
limitation,  architects,  engineers and other design professionals) in preparing
the Specification  Notice, and Tenant shall, upon payment, be entitled to copies
of all plans,  specifications  and designs.  Tenant's failure to timely exercise
the Tenant  Subdivision  Option or the  Leasehold  Improvement  Option  shall be
conclusively  deemed to constitute a rescission of the exercise of the Expansion
Option. Time is of the essence of this provision.

     26.3 If the Expansion Notice proposes that Tenant  constructs the Expansion
Improvements  and requests  that Landlord  purchase the Expansion  Improvements,
then not later  than sixty (60) days after  delivery  of the  Expansion  Notice,
Landlord  shall notify Tenant whether or not it elects to purchase the Expansion
Improvements  (which election shall be in Landlord's sole  discretion),  and the
provisions  of subsection  (a) or (b) of this Section 26.3, as applicable  shall
apply.

     (a) In the event Landlord shall have notified  Tenant that Landlord  elects
to purchase the Expansion  Improvements  (the  "Purchase  Notice"),  then Tenant
shall undertake construction of the Expansion Improvements ("Tenant's Work") and
the provisions of Section  26.3(a)(i) through  26.3(a)(ix)  hereinbelow shall be
applicable

          (i) Tenant shall cause to be constructed the Expansion Improvements in
     accordance   with  all  applicable   laws  and  the  procedures  set  forth
     hereinbelow.  Upon the  Expansion  Rent  Commencement  Date (as  defined in
     Section  26.4(a)),  Landlord  shall  purchase  and  Tenant  shall  sell the
     Expansion  Improvements  for a net price equal to Tenant's  Expansion Costs
     (as defined  below),  and Tenant shall execute and deliver to Landlord such
     documents and instruments as Landlord may reasonably  request in connection
     with such purchase and sale. The term "Tenant's  Expansion Costs" means all
     hard and soft  costs  incurred  by Tenant  (but  excluding  land  costs) in
     connection with the design and construction of the Expansion  Improvements,
     as said term may be further defined in the Lease Amendment described below.
     Tenant shall pay all closing  costs in  connection  with such  purchase and
     sale,  including the premium for an endorsement to Landlord's  title policy
     to increase  the  liability  amount to reflect  the price of the  Expansion
     Improvements.  From and after the Expansion Rent  Commencement Date and for
     the remainder of the term (as the same may be extended  pursuant to Section
     26.4(c)),  Tenant pay Expansion  Base Rent (as defined in Section  26.4(a))
     for the Expansion Improvements;  the Expansion Improvements shall be deemed
     to be a part of the Premises hereunder;  and Tenant shall pay all Operating
     Expenses for the Expansion  Improvements as set forth in Section 3.1(b) and
     shall  perform all other  obligations  of Tenant under this Lease as if the
     Expansion   Improvements  were  part  of  the  original  Premises.  At  the
     conclusion of this Lease, the Expansion  Improvements shall be delivered to
     Landlord in good condition  (reasonable  wear and tear excepted).  Title to
     the  Expansion  Improvements  shall,  at all  times,  remain in the name of
     Landlord and shall not pass to Tenant.

                                       47


          (ii) On or before ten (10) days from the date of the Purchase  Notice,
     Tenant  shall notify  Landlord of the  identity and mailing  address of the
     licensed  architect  engaged  by Tenant  for the  preparation  of plans for
     Tenant's  Work.  On or  before  forty-five  (45)  days from the date of the
     Purchase  Notice,   Tenant,  at  Tenant's  expense,  shall  cause  Tenant's
     architect  to prepare  and deliver to Landlord  for  Landlord's  reasonable
     approval five (5) sets of final plans and specifications for Tenant's Work.

          (iii) Landlord shall review said plans and  specifications  and notify
     Tenant within fifteen (15) days of receipt of said plans and specifications
     in Landlord's  office, of the matters,  if any, in said plans which fail to
     conform to Landlord's  construction  requirements or otherwise fail to meet
     with Landlord's approval which approval shall not be unreasonably withheld,
     conditioned or delayed.  Tenant shall, within ten (10) days from receipt of
     any such  notice  from  Landlord,  cause  said  plans to be revised in such
     manner as is requisite to  obtaining  Landlord's  approval and shall submit
     revised plans for Landlord's approval.  When Landlord has approved Tenant's
     plans,  Landlord  shall initial and return one (1) set of approved plans to
     Tenant, which set shall also show the date of Landlord's approval. Tenant's
     Work  shall be  carried  out  pursuant  to a fixed  price or  not-to-exceed
     construction  contract in form and  substance  reasonably  satisfactory  to
     Landlord,  and  with  a  licensed  contractor  reasonably  satisfactory  to
     Landlord.  Landlord  shall have the right to  require  that  Tenant  obtain
     payment and  completion  bonds on terms  satisfactory  to Landlord prior to
     commencing Tenant's Work. Tenant agrees not to commence Tenant's Work until
     Landlord has approved the final plans,  the contractor and the construction
     contract,  all  required  permits  have been issued and this Lease has been
     amended in accordance with section 26.8.  Tenant shall  reimburse  Landlord
     for actual costs expended for review of all plans.

          (iv)  Tenant  shall  not  deviate  from the  final  set of  plans  and
     specifications  approved  by  Landlord  without  Landlord's  prior  written
     consent,  which  consent  shall not be  unreasonably  withheld.  Landlord's
     approval of plans and specifications shall not constitute the assumption of
     any  responsibility by Landlord for any of Tenant's Work or the accuracy or
     sufficiency of Tenant's plans and specifications.
<PAGE>
                                       48


          (v) If Tenant fails to complete the Tenant's Work in  accordance  with
     such  plans  and  specifications  prior to the  Construction  Deadline  (as
     defined below),  Landlord,  at Landlord's  option, may terminate this Lease
     or, at Landlord's  option, may enter the Expansion  Improvements,  complete
     Tenant's  Work,  and Tenant  shall pay the cost  thereof to  Landlord  upon
     demand.  The term  "Construction  Deadline"  means the date  eighteen  (18)
     months after  commencement  of  construction,  plus the number of days that
     construction is delayed due to Force Majeure; provided that such date shall
     be extended an additional six (6) months so long as Tenant is  continuously
     and diligently proceeding with construction.

          (vi) Tenant shall  comply with and shall  require its  contractors  to
     comply with all federal, state, and local laws, ordinances, regulations and
     directions  relating to the employment,  conditions of employment and hours
     of labor in connection with any construction,  alteration,  installation or
     repair work done by or for Tenant in or about the Premises.  If Landlord is
     damaged  as a result of any  breach by  Tenant of these  covenants,  Tenant
     shall pay to Landlord the amount of such damage, upon demand.

          (vii) Upon completion of  construction of the Expansion  Improvements,
     Tenant shall submit:

               (1)  Properly  notarized  final  releases of liens from  Tenant's
          general contractor and all subcontractors.

               (2)  Properly  notarized  final  releases of liens from  Tenant's
          major suppliers, architect or anyone supplying a significant amount of
          materials  or  services  for  the   construction   of  the   Expansion
          Improvements.

               (3) A certificate of occupancy and a final inspection  report (as
          applicable) from the appropriate  governing body,  indicating that the
          Expansion Improvements has no violation of local building codes.

          (viii) At all times prior to the completion of Tenant's  Work,  Tenant
     shall cause its general  contractor  and  subcontractors  to maintain  such
     insurance as Landlord  may  reasonably  require,  with  insurance  carriers
     reasonably  approved  by  Landlord,   in  amounts  reasonably  approved  by
     Landlord.

                                       49


          (ix)  Tenant's  Work  shall  be  completed,  lien-free  in a good  and
     workmanlike  manner,  and shall constitute Class A office space constructed
     to the same  standards as the existing  Building.  Tenant  hereby agrees to
     indemnify,  defend and hold Landlord harmless from any and all liens and/or
     claims placed against the Premises,  arising out of, or in connection with,
     Tenant's Work; and  notwithstanding  anything to the contrary  contained in
     this Lease, no liens of any nature,  whether voluntary or involuntary,  may
     be placed or allowed by Tenant on the  Premises.  However,  Tenant may bond
     around any mechanic's  liens within thirty (30) days of recording,  without
     an Event of Default  occurring.  Landlord  shall have no  liability  of any
     kind,  and Tenant  shall be solely  responsible,  for any  defects or legal
     violations respecting the Expansion  Improvements.  Tenant hereby agrees to
     indemnify,  defend and hold  Landlord  harmless from any and all claims and
     liabilities  of any kind,  howsoever  arising,  relating  to the  Expansion
     Improvements and Tenant shall execute an indemnity, reasonably satisfactory
     to Landlord in form and content, prior to commencement of Tenant's Work.

     (b) In the event Landlord shall have notified  Tenant that Landlord  elects
not to purchase the Expansion  Improvements,  then Tenant may elect,  by written
notice  to  Landlord  within  sixty  (60) days  following  Tenant's  receipt  of
Landlord's  notice,  to either (A) rescind its exercise of the Expansion Option,
(B)  exercise  the  Leasehold  Improvement  Option,  or (C)  exercise the Tenant
Subdivision  Option.  Tenant's failure to timely exercise the Tenant Subdivision
Option or the  Leasehold  Improvement  Option  shall be  conclusively  deemed to
constitute a rescission of the exercise of the Expansion Option.  Time is of the
essence of this provision.

     26.4  (a)  Base  Rent  for  the  Expansion  Improvements  if the  Expansion
Improvements are constructed by Landlord or if Landlord  purchases the Expansion
Improvements  in  accordance  with  section  26.3(a)  ("Expansion  Base  Rent"),
calculated  as provided in Section  26.4(b),  shall  commence upon the date (the
"Expansion Rent Commencement Date") the Expansion Improvements are substantially
completed, subject only to "punch list" items and other items of incomplete work
that do not  materially  interfere  with the use and  occupancy of the Expansion
Improvements (as certified to Landlord and Tenant by the supervising  architect,
or, as evidenced by the  issuance of a temporary  or  permanent  certificate  of
occupancy), and delivered to Tenant for Tenant's occupancy.  Expansion Base Rent
shall be  included  in "Base  Rent" for  purposes  of this  Lease,  and shall be
payable  concurrently  with  payments  of Base  Rent  hereunder  as set forth in
Article 3 of this Lease.  From and after the Expansion Rent  Commencement  Date,
the  Expansion  Improvements  shall  be  deemed  to be a part  of  the  Premises
hereunder,  and in  addition  to  Expansion  Base  Rent,  Tenant  shall  pay all
Operating Expenses for the Expansion Improvements as set forth in Section 3.1(b)
and shall  perform all other  obligations  of Tenant  under this Lease as if the
Expansion Improvements were part of the original Premises.

                                       50


     (b) If  the  Expansion  Improvements  are  constructed  by  Landlord  or if
Landlord  purchases  the  Expansion  Improvements  in  accordance  with  section
26.3(a),  Expansion  Base Rent shall be: (i) for the first  twelve  (12)  months
after the Expansion  Rent  Commencement  Date,  an amount  calculated to provide
Landlord with an annual return on Landlord's investment of Total Expansion Costs
(as defined below) equal to the Rent Yield (as defined below), and (ii) for each
successive twelve (12) month period  thereafter,  an amount equal to one hundred
three percent  (103%) of the Expansion  Base Rent in effect during the preceding
12-month period.  The term "Total Expansion Costs" means all hard and soft costs
incurred by Landlord (including a reasonable development fee payable to Landlord
and financing  charges,  but excluding land costs) in connection with the design
and  construction  of the  Expansion  Improvements,  as said term may be further
defined in the Lease Amendment  described below. In the event Landlord purchases
the Expansion Improvements in accordance with Section 26.3(a),  "Total Expansion
Costs"  shall mean  Tenant's  Expansion  Costs.  The term "Rent  Yield"  means a
percentage  equal to Landlord's  Spread (as defined below) plus the Assumed Loan
Constant (as defined below).  The term  "Landlord's  Spread" means (x) if, as of
the  Expansion  Rent  Commencement  Date,  Tenant shall have  satisfied the debt
rating conditions set forth in Section 24.7, seventy-five (75) basis points; and
(y) if,  as of the  Expansion  Rent  Commencement  Date,  Tenant  shall not have
satisfied  the debt rating  conditions  set forth in Section  24.7,  one hundred
twenty-five  (125)  basis  points.  The term  "Assumed  Loan  Constant"  means a
percentage equal to the percentage of Total Expansion Costs which Landlord would
be required to pay  annually  as debt  service on a secured  loan in a principal
amount equal to Total  Expansion  Costs,  with  amortization of principal over a
term which ends five (5) years  after the term of this Lease (as the same may be
extended  pursuant to Section  26.4(c)) and interest at the then prevailing rate
(determined  with reference to loan terms being proposed by major life insurance
company  lenders  such as  Principal  Mutual,  Metropolitan  Life  and  Teachers
Insurance) for fully amortizing mortgage loans of like tenor secured by property
comparable to the Premises. Effective upon the Expansion Rent Commencement Date,
the Security  Amount  shall be  increased  by an amount equal to twenty  percent
(20%) of the Total Expansion Costs,  provided that the Security Amount shall not
be required  to exceed ten million  dollars  ($10,000,000).  Effective  upon the
Expansion Rent Commencement  Date, Section 24.6 shall be amended to provide that
the first Reduction Date shall occur on the fourth (4th) April 15 to occur after
the Expansion Rent Commencement Date, and subsequent Reduction Dates shall occur
annually  thereafter  (but the Reduction  Amounts  applicable on the  successive
Reduction Dates shall remain as set forth in Section 24.6).

     (c) In the event the  Expansion  Commencement  Date  occurs  later than the
third (3rd)  anniversary of the Commencement  Date, the term of this Lease shall
automatically be extended such that the Expiration Date shall be the date twelve
(12) years after the  Expansion  Commencement  Date.  If Landlord  constructs or
purchases the Expansion  Improvements,  Base Rent for the extended term shall be
calculated  in accordance  with section 3.1 based upon the Base Rent  (including
Expansion Base Rent).

                                       51


     26.5 In the event that Landlord elects not to undertake construction of the
Expansion  Improvements  or elects not to purchase  the  Expansion  Improvements
pursuant to Section 26.3(a),  and Tenant exercises the Tenant Subdivision Option
and elects to undertake  construction of the Expansion  Improvements  ("Tenant's
Work"),  the provisions of Section 26.5(a) through 26.5(f)  hereinbelow shall be
applicable.

     (a) Tenant shall,  at its sole cost and expense and upon and subject to the
terms of this Section 26.5 and the other  applicable  provisions of this Article
26, (A) cause the  Premises to be  subdivided  so that the  Expansion  Site is a
separate legal parcel,  (B) purchase the Expansion  Site from Landlord,  and (C)
cause to be  constructed  the  Expansion  Improvements  in  accordance  with all
applicable laws and the procedures set forth  hereinbelow.  For the remainder of
the term of this Lease, the Expansion Site and the Expansion  Improvements shall
not be a part of the Premises hereunder.

     (b) On or before  forty-five (45) days after the date of Tenant's  exercise
of the Tenant Subdivision Option, Tenant, at Tenant's expense, shall (A) cause a
registered  surveyor  or civil  engineer  to prepare  and  deliver to Landlord a
proposed  subdivision  map (the "Proposed  Subdivision  Map"),  complying in all
respects with all laws, statutes, codes and ordinances,  to legally separate the
Expansion Site and the remainder of the Premises (the  "Remaining  Parcel") such
that each parcel complies with all applicable laws, statutes,  codes, ordinances
and covenants, conditions and restrictions ("Legal Requirements"), and (B) cause
Tenant's  architect to prepare and deliver to Landlord for  Landlord's  approval
five (5) sets of final plans and  specifications  for Tenant's Work  including a
detailed  depiction  of all  proposed  improvements  (the  "Final  Plans").  The
Proposed  Subdivision Map shall be subject to Landlord's  approval,  which shall
not be  unreasonably  withheld.  Without  limiting the  foregoing,  Landlord may
disapprove  the Proposed  Subdivision  Map if (1) Landlord  would be required to
expend any sums to improve the Remaining  Parcel to cause it to be in compliance
with any Legal  Requirements,  (2) the  Remaining  Parcel  would,  in Landlord's
reasonable  judgment,  be of less value than the value prior to the  subdivision
minus  the  Site  Price  (as  defined  below),  or (3) the  expense  of  owning,
operating,  managing or maintaining  the Remaining  Parcel would be increased by
the subdivision.  Landlord shall review the Proposed  Subdivision Map and notify
Tenant within fifteen (15) days of receipt of the matters, if any, which fail to
conform to Landlord's reasonable requirements.

     (c) Landlord  shall review the Final Plans and notify Tenant within fifteen
(15) days of receipt of said plans and  specifications in Landlord's  office, of
the matters,  if any, in said plans which fail to meet with Landlord's  approval
<PAGE>
                                       52



which  approval  shall not be  unreasonably  withheld,  conditioned  or delayed.
Tenant  shall,  within  ten (10)  days  from  receipt  of any such  notice  from
Landlord, cause the Proposed Subdivision Map and/or the Final Plans, as the case
may be, to be revised in such manner as is  requisite  to  obtaining  Landlord's
approval and shall submit a revised Proposed  Subdivision Map and/or Final Plans
for Landlord's approval. The Proposed Subdivision Map as approved by Landlord is
referred  to  herein  as  the  "Subdivision  Map."  As  promptly  as  reasonably
practicable  after  Landlord's  approval  of the  Subdivision  Map and the Final
Plans,  Tenant shall cause the Subdivision Map to be recorded and shall take all
other steps necessary to cause the Premises to be subdivided.  Tenant agrees not
to commence  Tenant's Work until Landlord has approved the  Subdivision  Map and
the Final Plans, the Premises has been legally subdivided in accordance with the
approved  Subdivision Map, Tenant has purchased the Expansion Site in accordance
with this Section 26.5, all required permits have been issued and this Lease has
been amended in accordance with Section 26.8.  Tenant shall  reimburse  Landlord
for actual  costs  expended  for review of all maps and plans.  Tenant shall not
materially  deviate from the Final Plans approved by Landlord without Landlord's
prior written  consent,  which shall not be  unreasonably  withheld.  Landlord's
approval of plans and specifications  shall not constitute the assumption of any
responsibility  by  Landlord  for  any  of  Tenant's  Work  or the  accuracy  or
sufficiency of Tenant's plans and specifications.

     (d) Immediately  upon  recordation of the Subdivision Map and completion of
all  procedures  necessary  to legally  subdivide  the  Premises,  Tenant  shall
purchase the Expansion Site from Landlord for a price (the "Site Price"), net to
Landlord,  equal to the  product of (i) the number of gross  square feet of land
area in the Expansion Site, multiplied by (ii) the Square Foot Price (as defined
below) in effect as of the date of the sale.  The term "Square Foot Price" means
(A) during the twelve (12) month period  commencing  on the  Commencement  Date,
seven and one-half  dollars ($7.50) (the "Initial  Price"),  and (B) during each
successive twelve (12) month period, the Initial Price increased by five percent
(5%) per year on a compounded  basis.  Tenant shall bear all costs and expenses,
and shall reimburse Landlord for all costs and expenses incurred by Landlord, in
connection with such purchase, including the subdivision of the Premises and the
Lease  Amendment.  After  the  recordation  of  the  Subdivision  Map  and  upon
completion of the sale of the Expansion Site to Tenant,  Tenant shall be subject
to no further  restriction  on encumbrance of the Expansion Site with a mortgage
or deed of trust.

     (e) If Tenant fails to commence  construction  of Tenant's work within nine
(9) months  after  delivery of the  Expansion  Notice or fails to  complete  the
Tenant's  Work in  accordance  with the Final  Plans  prior to the  Construction
Deadline,  Landlord, at Landlord's option, may rescind the sale of the Expansion
Site in which case the sale of the Expansion Site shall be reversed (with Tenant
conveying  the  Expansion  Site to  Landlord  at a net  price  equal to the Site
Price), and Tenant shall be deemed to have elected not to exercise the Expansion
Option.
<PAGE>
                                       53


     (f) Landlord and Tenant  acknowledge  that the  subdivision of the Premises
and  construction  of the Expansion  Improvements  will require  modification of
and/or additions to the parking facilities on the Premises.  Landlord and Tenant
shall include in the Final Plans provisions for parking  facilities serving both
the existing Building and the Expansion  Improvements.  Such parking  facilities
shall be designed and constructed at Tenant's sole cost and expense. If adequate
parking  facilities are not constructed on each respective  parcel sufficient to
serve that  parcel and it is  necessary  or  appropriate  to  construct  parking
facilities  on one of the  parcels to provide  parking  for both  parcels,  then
Landlord and Tenant shall enter into an appropriate perpetual access and parking
easement simultaneously with Tenant's purchase of the Expansion Site.

     26.6 In the event that Landlord elects not to undertake construction of the
Expansion  Improvements  or elects not to purchase  the  Expansion  Improvements
pursuant to Section  26.3(a),  and Tenant  exercises the  Leasehold  Improvement
Option  and  elects to  undertake  construction  of the  Expansion  Improvements
("Tenant's Work"), the provisions of Section 26.6(a) through 26.6(c) hereinbelow
shall be applicable.

     (a) Tenant shall cause to be  constructed  the  Expansion  Improvements  in
accordance  with all applicable  laws and the procedures set forth  hereinbelow.
Landlord  shall have no obligation to purchase the Expansion  Improvements,  and
Tenant shall,  for the remainder of the term, pay no Expansion Base Rent for the
Expansion  Improvements,  but the Expansion Improvements shall be deemed to be a
part of the Premises hereunder,  and Tenant shall pay all Operating Expenses for
the Expansion  Improvements as set forth in Section 3.1(b) and shall perform all
other  obligations  of Tenant under this Lease as if the Expansion  Improvements
were  part of the  original  Premises.  At the  conclusion  of this  Lease,  the
Expansion  Improvements  shall  be  delivered  to  Landlord  in  good  condition
(reasonable wear and tear excepted).  Title to the Expansion Improvements shall,
at all  times,  remain in the name of  Landlord  and  shall not pass to  Tenant.
Landlord  shall  have no  liability  of any  kind,  and  Tenant  shall be solely
responsible,  for any  defects  or legal  violations  respecting  the  Expansion
Improvements in the event Tenant performs Tenant's Work. Tenant hereby agrees to
indemnify,  defend  and  hold  Landlord  harmless  from any and all  claims  and
liabilities  of  any  kind,   howsoever  arising,   relating  to  the  Expansion
Improvements and Tenant shall execute an indemnity,  reasonably  satisfactory to
Landlord in form and content, prior to commencement of Tenant's Work.

     (b) The design and  construction  of the  Expansion  Improvements  shall be
carried  out in  accordance  with the  terms  of  Sections  26.3(a)(ii)  through
26.3(a)(ix),  all of which shall be applicable to Tenant's Work pursuant to this
Section 26.6.
<PAGE>
                                       54


     (c)  Notwithstanding  that  Tenant  may  pay for  the  construction  of the
Expansion Improvements, if an Event of Default occurs, Landlord shall retain all
rights in law and equity against  Tenant,  including,  without  limitation,  the
right to dispossess Tenant from the Expansion  Improvements without compensation
for the cost thereof.

     26.7 Anything in this Article 26 to the contrary notwithstanding,  Tenant's
notice of exercise of the Expansion Option or the Tenant  Subdivision  Option or
the Leasehold Improvement Option shall be effective, only if at the time of such
notice of exercise the following  conditions (the "Expansion  Conditions") shall
be satisfied:

          (i) Landlord shall not have notified  Tenant that Tenant is in default
     in the performance of any of the terms,  covenants or conditions  contained
     in this Lease which default has not been cured within any applicable  grace
     period or cure period.

          (ii) This Lease  shall not have been  terminated  and shall be in full
     force and effect.

          (iii) There shall have been no assignment of Tenant's interest in this
     Lease except to a Corporate  Successor as permitted by Section 12.1 hereof.
     Tenant  acknowledges  that the  Expansion  Option  and all other  rights of
     Tenant under this Article 26 are personal to Tenant, and not a right of any
     successor to the rights of Tenant under this Lease.

          (iv) There shall have been no material adverse change in the financial
     condition of Tenant or the Guarantor since the execution of this Lease, and
     Landlord shall determine,  at its sole reasonable  discretion,  that Tenant
     and Guarantor are each creditworthy in light of the obligations  undertaken
     pursuant  to this Lease and the other  existing  obligations  of Tenant and
     Guarantor.
<PAGE>
                                       55


     26.8 Notwithstanding anything to the contrary herein, promptly after Tenant
accepts the proposal in Landlord's  Specification  Notice, or Landlord elects to
purchase  the  Expansion  Improvements  pursuant to Section  26.3(a),  or Tenant
exercises the Tenant Subdivision Option or the Leasehold  Improvement Option, as
the case may be, Landlord and Tenant shall enter into an amendment to this Lease
(the "Lease  Amendment")  setting  forth the terms of the expanded  lease or the
terms relating to Tenant's  Subdivision Option or Leasehold  Improvement Option,
in form and substance  mutually  agreeable to Landlord and Tenant which shall be
consistent with the applicable terms of this Article 26.

                            CONTINUING LEASE GUARANTY


     THIS GUARANTY, made as of ___________ __, ____, by  _______________________
("Guarantor") to __________________ ("Landlord").

                              W I T N E S S E T H:

     1. For valuable  consideration,  receipt of which is  acknowledged,  and to
satisfy certain  requirements under the Lease dated  _____________ __, 19__ (the
"Lease") between Landlord and __________________________  ("Tenant"),  Guarantor
hereby absolutely,  unconditionally and irrevocably  guarantees to Landlord, and
agrees fully to pay, perform and discharge, as and when payment, performance and
discharge are due, all of the covenants,  obligations  and liabilities of Tenant
under  the  Lease  and  all  amendments,  modifications,  renewals,  extensions,
supplements,  substitutions  and  replacements  of the Lease arising  during the
period  beginning  on the date  hereof and ending on the date this  Guaranty  is
terminated (the  "Guaranteed  Obligations").  The obligations of Guarantor under
this  Guaranty  shall be  absolute,  unconditional  and  irrevocable  and  shall
continue  and  remain in full  force  and  effect  until  all of the  Guaranteed
Obligations have been fully paid, performed and discharged.

     2. The  obligations of Guarantor under this Guaranty shall not be affected,
modified or impaired by the occurrence of any of the following  events,  whether
or not with notice to, or the consent of, Guarantor: (a) the waiver,  surrender,
compromise,  settlement,  release or termination of any or all of the Guaranteed
Obligations; (b) the failure to give notice to Guarantor of the occurrence of an
event of default under the Guaranteed Obligations; (c) the extension of the time
for  the  payment,  performance  or  discharge  of any or all of the  Guaranteed
Obligations;  (d) the amendment or modification  (whether material or otherwise)
of the Guaranteed Obligations in any respect; (e) any failure,  omission,  delay
or lack on the part of Landlord to enforce,  assert or exercise any right, power
or remedy  conferred  on  Landlord  under the  Guaranteed  Obligations;  (f) the
voluntary or involuntary liquidation,  dissolution, sale or other disposition of
all or substantially  all of the assets,  marshalling of assets and liabilities,
receivership,  insolvency,  bankruptcy, assignment for the benefit of creditors,
reorganization,  arrangement, composition with creditors or adjustment of debts,
or other similar proceedings  affecting Tenant or Guarantor or any of the assets
of either of them;  (g) the release or  discharge  by operation of law of Tenant
from the  payment,  performance  or  discharge  of any or all of the  Guaranteed
Obligations;  (h) the release or discharge by operation of law of Guarantor from
any or all of the  obligations  of  Guarantor  under this  Guaranty;  or (i) the
invalidity  or  unenforceability  of any or all of the  Guaranteed  Obligations.
Guarantor acknowledges that Landlord would not enter into the Lease without this
Guaranty and that Landlord is relying on this Guaranty.

                                       2


     3. The  obligations of Guarantor under this Guaranty are independent of the
Guaranteed  Obligations.  Guarantor agrees that Landlord shall have the right to
proceed  against  Guarantor  directly and  independently  of Tenant.  A separate
action may be brought and prosecuted  against Guarantor whether or not an action
is  brought  against  Tenant or Tenant is joined in any such  action.  Guarantor
authorizes  Landlord and Tenant,  without  notice to, demand of, or consent from
Guarantor and without  releasing or affecting  Guarantor's  liability under this
Guaranty,  from time to time to amend,  modify,  renew,  extend,  supplement  or
replace  the  Guaranteed  Obligations  or  otherwise  change  the  terms  of the
Guaranteed   Obligations,   to  take  and  hold  security  for  the   Guaranteed
Obligations, and to enforce, waive, surrender, impair, compromise or release any
such  security  or any or all of the  Guaranteed  Obligations  or any  person or
entity liable for any or all of the Guaranteed  Obligations.  Guarantor shall be
and remain bound under this Guaranty notwithstanding any such act or omission by
Tenant or Landlord.  Guarantor  waives the right, if any, to require Landlord to
proceed  against  Tenant,  to proceed  against or exhaust any  security  held by
Landlord, or to pursue any other remedy in Landlord's power. Landlord shall have
the right to exercise or enforce any right or remedy  Landlord  may have against
Tenant or any security held by Landlord.  Guarantor waives the right, if any, to
the benefit of, or to direct the  application of, any security held by Landlord.
Guarantor  waives (a) any defense  arising out of any alteration of the original
Guaranteed Obligations,  (b) any defense arising out of the absence,  impairment
or loss of any right of reimbursement or subrogation or other right or remedy of
Guarantor  against Tenant or any security held by Landlord,  and (c) any defense
arising by reason of any  disability  or other defense of Tenant or by reason of
the cessation or reduction from any cause  whatsoever of the liability of Tenant
other  than  full  payment,   performance   and  discharge  of  the   Guaranteed
Obligations.  The  cessation  or  reduction  of the  liability of Tenant for any
reason  whatsoever  other than full  payment,  performance  and discharge of the
Guaranteed  Obligations  shall not release or affect in any way the liability of
Guarantor under this Guaranty.

     4. If  Tenant  becomes  insolvent  or is  adjudicated  bankrupt  or files a
petition for  reorganization,  arrangement,  composition or similar relief under
any present or future  provision of the federal  Bankruptcy  Code,  or if such a
petition is filed against  Tenant,  or if Tenant makes a general  assignment for
the  benefit  of  creditors,  and  in  any  such  proceeding  any  or all of the
Guaranteed  Obligations  are  terminated  or  rejected  or  any  or  all  of the
Guaranteed  Obligations  are modified or abrogated,  then Guarantor  agrees that
Guarantor's  liability  under this  Guaranty  shall not  thereby be  affected or
modified  and such  liability  shall  continue in full force and effect as if no
such action or proceeding  had  occurred.  This  Guaranty  shall  continue to be
effective or be reinstated, as the case may be, if any payment of the Guaranteed
Obligations  must be returned by Landlord  upon the  insolvency,  bankruptcy  or
reorganization of Tenant or Guarantor,  or otherwise, as though such payment had
not been made.
<PAGE>
                                       3


     5. Guarantor  assumes the  responsibility  for being and keeping  Guarantor
informed of the  financial  condition  of Tenant and of all other  circumstances
bearing  upon  the risk of  failure  to pay,  perform  or  discharge  any of the
Guaranteed Obligations which diligent inquiry would reveal, and Guarantor agrees
that Landlord has no duty to advise  Guarantor of information  known to Landlord
regarding such condition or any such circumstance.  Guarantor  acknowledges that
repeated and  successive  demands may be made and payments or  performance  made
hereunder  in response to such  demands as and when,  from time to time,  Tenant
defaults in the payment, performance or discharge of the Guaranteed Obligations.
Notwithstanding any such payments and performance hereunder, this Guaranty shall
remain  in full  force and  effect  and  shall  apply to any and all  subsequent
defaults  by Tenant.  It is not  necessary  for  Landlord  to  inquire  into the
capacity,  authority or powers of Tenant or the partners,  directors,  officers,
employees,  agents or  representatives  acting or purporting to act on behalf of
Tenant,  and all of the Guaranteed  Obligations made or created in reliance upon
the purported exercise of such powers shall be guaranteed under this Guaranty.

     6. If Tenant and Guarantor fail to pay, perform and discharge,  as and when
payment,  performance and discharge are due, all of the Guaranteed  Obligations,
Landlord shall have the right, but no obligation,  and without  releasing Tenant
or  Guarantor  from  any of the  Guaranteed  Obligations,  to pay,  perform  and
discharge  any or all of the  Guaranteed  Obligations  on behalf  of Tenant  and
Guarantor.  Guarantor  shall,  on demand,  pay to Landlord all sums  expended by
Landlord  in  the  payment,   performance   and  discharge  of  the   Guaranteed
Obligations,  together  with  interest  on  all  such  sums  from  the  date  of
expenditure  to the date  all such  sums are  paid by  Tenant  or  Guarantor  to
Landlord at the Interest  Rate (as defined in the Lease).  Guarantor  waives all
presentments,  demands for  performance,  notices of  nonperformance,  protests,
notices of  protest,  notices of  dishonor  and  notices of  acceptance  of this
Guaranty.  Guarantor agrees to pay all costs and expenses,  including reasonable
attorneys'  fees and  disbursements,  which  are  incurred  by  Landlord  in the
enforcement  of this  Guaranty.  If any provision of this Guaranty is held to be
invalid or unenforceable, the validity or enforceability of the other provisions
of this Guaranty shall not be affected. If there is more than one Guarantor, all

<PAGE>
                                       4


obligations  of  Guarantor  under this  Guaranty  shall be the joint and several
obligations of each  Guarantor.  This Guaranty may not be amended or modified in
any respect except by a written instrument signed by Guarantor and Landlord.  As
used in this  Guaranty,  the singular  shall  include the plural.  This Guaranty
shall  bind and  inure to the  benefit  of  Guarantor  and  Landlord  and  their
respective transferees, personal representatives, heirs, successors and assigns.
This Guaranty shall be governed by and construed in accordance  with the laws of
the  State  where the  premises  leased by Tenant  from  Landlord  are  located.
Guarantor hereby irrevocably  consents to the non-exclusive  jurisdiction of the
courts of the States of Colorado  and  California  and any federal  court of the
United States of America  located in the City of San Francisco,  California,  or
the city of Denver,  Colorado.  Guarantor  and Landlord  each waive any right to
trial by jury in connection  herewith.  Without limiting anything else contained
herein,  the  fullest  extent it may  effectively  do so under  applicable  law,
Guarantor  irrevocably  waives and agrees not to assert,  by way of motion, as a
defense or otherwise,  any claim that it is not subject to the  jurisdiction  of
any such court, any objection that it may now or hereafter have to the laying of
the venue of any such suit,  action or proceeding  brought in any such court and
any claim that any such suit, action or proceeding brought in any such court has
been brought in an inconvenient forum.

     7. To induce  Landlord to enter into the Lease,  Guarantor  represents  and
warrants to Landlord as follows:  Guarantor is a corporation  existing under the
laws of the ________ of  _________.  Guarantor  has full power and  authority to
enter into this Guaranty and to perform its obligations under this Guaranty. The
execution, delivery and performance of this Guaranty by Guarantor have been duly
and validly  authorized by all necessary action on the part of Guarantor and all
required  consents and  approvals  have been duly  obtained.  This Guaranty is a
legal, valid and binding obligation of Guarantor,  enforceable against Guarantor
in accordance  with its terms,  subject to the effect of applicable  bankruptcy,
insolvency,  reorganization,  arrangement,  moratorium  or  other  similar  laws
affecting the rights of creditors generally.  Neither the execution and delivery
of this Guaranty nor the  consummation of the transactions  contemplated  hereby
will conflict with, or (with or without notice or lapse of time, or both) result
in a termination,  breach, impairment or violation of, or give rise to a default
under (i) any provision of Guarantor's articles of incorporation or bylaws, (ii)
any material  instrument  or contract to which  Guarantor is a party or by which
Guarantor is bound,  or (iii) any  federal,  state,  local or foreign  judgment,
writ, decree, order, statute, rule or regulation applicable to Guarantor, or any
property of Guarantor.

     IN WITNESS  WHEREOF,  Guarantor has executed this Continuing Lease Guaranty
as of the date first hereinabove written.

                                       Guarantor:

                       TRINET CORPORATE REALTY TRUST, INC.
                               SURVEY REQUIREMENTS

The following items are to be included in the ALTA/ACSM LAND TITLE SURVEY;

1.   Monuments placed (or a reference  monument or witness to the corner) at all
     major corners of the boundary of the  property,  unless  already  marked or
     referenced by an existing monument or witness to the corner,  except in the
     states of California,  Oregon and Washington,  wherein the local Government
     requires a record plat of new  monuments  set which  mandate  substantially
     higher fee to cover review costs.

2.   Flood zone  designation  (with property  annotation  based on Federal Flood
     Insurance  Rate  Maps or the  state  or local  equivalent,  by  scaled  map
     location and graphic plotting only). If the property resides in two or more
     zones  then the survey  shall  clearly  display  the limits of each zone by
     graphically transposing each zone line from the FIRM to the survey.

3.   Land area.

4.   Identify,  and show if possible,  setback,  height and bulk restrictions of
     record or disclosed by applicable  zoning or building codes (in addition to
     those recorded in subdivision maps). If none, so state.

5.   (a) Exterior dimensions of all buildings at ground level

     (b)  Square footage of exterior footprint of all buildings,  or gross floor
          area of all buildings, at ground level

     (c)  Height of all buildings above grade at a defined location.

6.   Parking areas and, if striped, the striping and the type (e.g. handicapped,
     motorcycle,  regular,  etc.) and number of parking  spaces.  Designate  all
     "handicapped" spaces as such on the survey. Show all striped parking spaces
     within the fee owned or leased  land and within the limits of all REAs with
     typical  sizes.  List in a tabular  format the number of regular spaces and
     handicap  spaces,  both  within the limits of the fee owned or leased  land
     plus within the limits of any and all REAs.

7.   Indication of access to a public way, such as curb cuts, driveways marked.

8.   Location of utilities serving or existing on the property,  as evidenced by
     on-site observation or as determined by records provided by client, utility
     companies and other appropriate sources (with reference as to the source of
     information).  For example:  (a) railroad tracks and sidings; (b) manholes,
     catch basins,  valve vaults or other surface  indications  of  subterranean
     uses; (c) wires and cables (including their function) crossing the surveyed
     premises,  all poles on or within ten feet of the surveyed premises and the
     dimensions of all crosswires or overhangs  affecting the surveyed premises;
     and (d) utility company installations on the surveyed premises.

                                       2


     In addition to the above the surveyor  shall report all visible roof drains
     and  surface  lines,  including  their  outfalls.  For  hidden  underground
     utilities the surveyor is to show the  approximate  location of underground
     connecting  lines as may be  discernible  from visible  appurtenances.  For
     hidden  underground  gravity  flow  as  may  be  discernible  from  visible
     appurtenances.

9.   Significant  observations not otherwise disclosed including but not limited
     to,  visible  evidence of unusual  subsurface  matters (such as underground
     storage  tanks as may be  apparent  by surface  appurtenances)  and general
     knowledge  about the  neighborhood  (such as condemnation of the area by US
     EPA) or restricted  building heights by the FFA. If the surveyor  questions
     what is to be reported or encounters a special reporting problem,  he is to
     consult with his client.

10.  Areas denoted or restricted in Reciprocal Easement Agreements ("REA").  The
     surveyor shall show the limits of any offsite appurtenant  easements on his
     survey,  but no improvements or utilities  within said easements need to be
     field measured and reported on the survey. However, the surveyor shall show
     the  outlines  of any  and all  buildings  within  the  REA by  transposing
     building location information from available site plans, aerial photographs
     or other plans and stating the source of such information on his survey. If
     no other  information is available showing the location of buildings within
     the REA, then the surveyor  shall advise the client prior to the completion
     of his survey.  If the client requires  additional field work to locate and
     report the location of buildings,  then this shall constitute an additional
     work order  beyond the scope of the  survey.  In the event the  property is
     disproportionately  smaller than the REA or appurtenant easements, then the
     surveyor  shall provide on his survey  smaller  (larger  scale)  drawing to
     depict the area affected in relationship to the fee or leased land.

11.  Add the limits of any REAs or offsite appurtenant and beneficial  easements
     to the  land  subject  to  your  survey  and  report  the  location  of all
     buildings, parking spaces and other improvements on those lands.

12.  Add a note after  your legal  description  stating  it  describes  the same
     property as insured in the title  commitment.  If there are  exceptions  to
     this statement, then qualify such within the note.

                      FIRST AMENDMENT TO PURCHASE AGREEMENT


     THIS FIRST AMENDMENT TO PURCHASE AGREEMENT (the "Amendment"), is made as of
January 15, 1998,  by and between ICG  HOLDINGS,  INC.,  a Colorado  corporation
("Seller"),  and TRINET  ESSENTIAL  FACILITIES  X, INC., a Maryland  corporation
("Buyer"), with reference to the following facts:

     A. Seller and Buyer entered into that certain Purchase Agreement,  dated as
of December 9, 1997 (the "Agreement"),  with respect to the purchase and sale of
the Property.  Each  capitalized  term used in this  Amendment,  but not defined
herein, shall have the meaning ascribed to it in the Agreement.

     B. Buyer and  Seller  have  agreed  that Buyer  shall  waive the  condition
precedent  to the Closing that the Project has been  Substantially  Completed by
the Closing Date, as set forth in Section  8.2(d) of the  Agreement,  as long as
one  hundred  thirty  percent  (130%) of the Unpaid  Project  Costs shall not be
disbursed  to Seller  at  Closing,  but is held in escrow to pay for the  Unpaid
Project Costs pursuant to the terms and provisions contained herein.

     C. Because the actual amount of Buyer's  out-of-pocket  costs in connection
with the Purchase Agreement and the transactions contemplated thereby, the Lease
and the  Project,  for which  Seller is  required to  reimburse  Buyer up to two
hundred fifty  thousand  dollars  ($250,000)  pursuant to Section  9.3(b) of the
Purchase  Agreement,  will not be determined  by Closing,  Buyer and Seller have
agreed  that two  hundred  eighteen  thousand  seven  hundred  ninety-seven  and
twenty-five  hundredths dollars ($218,797.25) of the Purchase Price shall not be
disbursed to Seller at Closing,  but shall be held in escrow to satisfy Seller's
obligation.

     D. Seller and Buyer desire to enter into this Amendment to modify the terms
of the Agreement, all as set forth hereinbelow.

     NOW, THEREFORE, the parties agree as follows:

     1. Holdback Escrow.  The Agreement is hereby amended by adding new Sections
2.3 through 2.5 thereto, which read in their entirety as follows:

          "2.3 Funds for Unpaid Project Costs Held in Escrow.

          "(a) Escrow Account-A. Buyer and Seller acknowledge that there will be
     Unpaid  Project Costs after the Closing Date. In order to assure Buyer that
     such Unpaid Project Costs will be paid promptly as they become due,  Seller
     and Buyer agree that,  upon and subject to the terms and conditions of this
     section 2.3 and an escrow  agreement  (the "Escrow  Agreement") in the form
     attached  hereto as Exhibit S, at the Closing,  one hundred  thirty percent
     (130%) of the Unpaid  Project Costs shall not be then  disbursed to Seller,
     and  shall be held in escrow by the  Escrow  Holder in an  interest-bearing
     escrow account ("Escrow Account-A"), pursuant to the Escrow Agreement. Such
     escrowed  funds are referred to herein as "Escrow  Amount-A".  All interest
     earned on Escrow Amount-A shall be paid to Seller. Escrow Amount-A shall be
     held and disbursed in accordance with the terms of this section 2.3 and the
     Escrow Agreement.
<PAGE>
                                       2


          "(b) Completion of Unfinished Work. Seller shall promptly complete all
     Unfinished  Work; in any event,  all Unfinished  Work shall be completed by
     Seller no later  than by June 30,  1998.  If Seller has not  completed  the
     Unfinished  Work by June 30, 1998,  Buyer may complete the Unfinished  Work
     and receive disbursements from Escrow Account-A upon Buyer's instruction to
     the  Escrow  Agent  to pay  for  the  costs  incurred  in  completing  such
     Unfinished  Work. If at any time Escrow  Amount-A is  insufficient to cover
     such costs incurred by Buyer to complete the Unfinished Work,  Seller shall
     promptly pay Buyer for such costs upon demand by Buyer,  as additional rent
     under the Lease.  Seller's  failure to pay such additional costs within ten
     (10) days after  demand  shall  constitute  an Event of  Default  under the
     Lease.

          "(c) Disbursements to Seller from Escrow Account-A.

          (i) Substantial Completion. From time to time, whenever Buyer receives
     evidence from Seller that Seller has paid for any  Unfinished  Work (in the
     form of one or more  invoices  together  with such lien  releases  or other
     evidence  of  payment  as Buyer  may  reasonably  require)  which  has been
     completed and is in place (as evidenced by an  architect's  certificate  or
     such other  evidence  as Buyer may  reasonably  require),  Buyer and Seller
     shall  instruct  the  Escrow  Holder  to  disburse  to Seller  from  Escrow
     Account-A  the amount paid by Seller for such  Unfinished  Work;  provided,
     however, that no disbursement from Escrow Account-A shall exceed the amount
     of the then remaining Escrow Amount-A.

          (ii) Punch-list  Items.  Upon satisfaction of the conditions set forth
     in Sections  7.5(i)(1)  through  7.5(i)(4)  and  7.5(i)(6)  (i.e.  once the
     Project is  Substantially  Completed),  Buyer and Seller shall instruct the
     Escrow Holder to disburse to Seller an amount equal to the remaining Escrow
     Amount-A less the amount  required to be held in escrow pursuant to Section
     7.5(j).  Buyer  and  Seller  shall  instruct  the  Escrow  Holder  to  make
     disbursements  to Seller from Escrow  Account-A  amounts  paid by Seller to
     complete the Punch-list Items pursuant to Section 2.3(c)(i).
<PAGE>
                                       3


          "(d) Termination of Escrow Agreement.  Buyer and Seller shall instruct
     the Escrow  Holder  that  Escrow  Account-A  shall be closed and the Escrow
     Agreement  shall  terminate  with  respect  to  Escrow  Account-A  and  any
     remaining  amounts  of Escrow  Amount-A  shall be paid to  Seller  upon the
     earlier to occur of the  following:  (i) all sums have been  disbursed from
     Escrow  Account-A  in  accordance  with this section 2.3; or (ii) Buyer has
     received  adequate  evidence  from  Seller  (in the form of an  architect's
     certificate or such other  evidence as Buyer may  reasonably  require) that
     the Punch-list Items have been completed in their entirety.

          "2.4 Funds for Out-of-Pocket Costs Held in Escrow.

          "(a) Escrow  Account-B.  Buyer and Seller  acknowledge that, after the
     Closing Date, there will be out-of-pocket costs which have been incurred by
     Buyer prior to the  Closing  Date and which will be incurred by Buyer after
     the  Closing  Date  that are  required  to be  reimbursed,  but will not be
     reimbursed  by the  Closing  Date,  by Seller  pursuant  to Section  9.3(b)
     ("Out-of-Pocket  Costs").  In order to assure Buyer that such Out-of-Pocket
     Costs will be paid  promptly  as they  become  due,  Seller and Buyer agree
     that,  upon and subject to the terms and conditions of this section 2.4 and
     the Escrow Agreement,  at the Closing,  two hundred eighteen thousand seven
     hundred  ninety-seven and twenty-five  hundredths dollars  ($218,797.25) of
     the Purchase Price shall not be then disbursed to Seller, and shall be held
     in  escrow  by the  Escrow  Holder in an  interest-bearing  escrow  account
     ("Escrow Account-B"), pursuant to the Escrow Agreement. Such escrowed funds
     are referred to herein as "Escrow Amount-B".  All interest earned on Escrow
     Amount-B  shall  be paid to  Seller.  Escrow  Amount-B  shall  be held  and
     disbursed in  accordance  with the terms of this section 2.4 and the Escrow
     Agreement.

          "(b) Disbursements to Seller from Escrow Account-B. From time to time,
     whenever  Seller   receives   evidence  from  Buyer  that  Buyer  owes  any
     Out-of-Pocket  Costs  (in the form of one or more  invoices  or other  such
     evidence as Seller may reasonably require), Buyer and Seller shall instruct
     the Escrow  Holder to disburse to Buyer from  Escrow  Account-B  the amount
     paid by Buyer for such  Out-of-Pocket  Costs;  provided,  however,  that no
     disbursement  from  Escrow  Account-B  shall  exceed the amount of the then
     remaining Escrow Amount-B.

          "(c) Termination of Escrow Agreement.  Buyer and Seller shall instruct
     the Escrow  Holder  that  Escrow  Account-B  shall be closed and the Escrow
     Agreement  shall  terminate  with  respect  to  Escrow  Account-B  and  any
     remaining  amounts  of Escrow  Amount-B  shall be paid to  Seller  upon the
     earlier to occur of the  following:  (i) all sums have been  disbursed from
     Escrow  Account-B  in  accordance  with this section 2.4; or (ii) Buyer and
     Seller  have  agreed  in  writing  that  Seller  has  fully  satisfied  its
     obligation to reimburse Seller for the Out-of-Pocket Costs.

          "2.5 Arbitration.

          "(a) Buyer and Seller agree that any dispute  respecting  their rights
     to Escrow Amount-A  and/or Escrow  Amount-B (the "Escrow  Amount") shall be
     determined  exclusively by final and binding arbitration in accordance with
     this  section  2.5.  In the  event  either  party  wishes  to  commence  an
     arbitration  proceeding  to resolve  any dispute  relating to the  parties'
     rights to the Escrow Amount, such arbitration shall be final and binding on
     Buyer and Seller,  shall be conducted in the County of Arapahoe,  Colorado,
     and shall be administered by and in accordance  with the  Comprehensive  or
     Streamlined  Arbitration  Rules and  Procedures of  J.A.M.S./Endispute,  as
     applicable,  or, if such rules no longer exist,  the then existing rules of
     practice  and  procedure  of  J.A.M.S./Endispute  (both  sets of rules  are
     collectively  referred  to  as  the  "Rules  of  J.A.M.S./Endispute").  The
     arbitrator  shall be a  retired  Colorado  or  federal  judge  selected  in
     accordance with the Rules of  J.A.M.S./Endispute.  The arbitrator and not a
     jury will decide the matter submitted to arbitration.

          "The arbitrator shall determine only the rights of Buyer and Seller to
     the Escrow Amount and no other issues.  Judgment upon any decision rendered
     by the  arbitrator  may be  entered by any state or  federal  court  having
     jurisdiction  thereof.  Subject to the final  sentence of this Section 2.5,
     the  arbitrator  shall have the power to award damages in  accordance  with
     this section 2.5 payable from Escrow  Account-A  and/or  Escrow  Account-B,
     whichever is applicable, and to order the disposition of the Escrow Amount,
     but shall not have the power to award any other  damages or grant any other
     relief,  and  shall  not have the  power  to vary  the  provisions  of this
     Agreement.

          "Discovery  in any  arbitration  shall  be  permitted  but it shall be
     limited to one deposition and the exchange of documents and witness lists.

          "Except as  otherwise  required  by law,  the  parties  agree that the
     arbitration  proceeding  will be  confidential;  all  conduct,  statements,
     promises,  offers,  views and  opinions,  oral or written,  made during the
     arbitration  by any party or a party's  agent,  employee or  attorney  will
     remain confidential and, where appropriate, will be considered work product
     and privileged;  and the existence and the results of the arbitration  will
     be maintained  by the parties and their  respective  agents,  employees and
     attorneys as confidential at all times.

          "In the event that J.A.M.S./Endispute is no longer in existence at the
     time that  arbitration  is  requested,  the dispute  shall be  submitted to
     arbitration in accordance with the rules and procedures of the successor to
     J.A.M.S./Endispute  or, if there is no such successor,  the matter shall be
     submitted  to  an  organization   which  consists  of  members  similar  to
     J.A.M.S./Endispute or its successor.

          "The losing party shall bear all of its own and the prevailing party's
     costs and expenses  incurred in connection with the arbitration,  including
     the arbitrator's fees and costs."

     2. Survey. The Agreement is hereby further amended as follows:

          (a) Subparagraph (5) of Section 7.5(i) is hereby deleted.

          (b)  Section  7.5(g)  is  hereby  replaced  in its  entirety  with the
     following paragraph:

               "7.5(g)  Surveys.  If  Buyer  requests  upon  completion  of  the
          Project,  Seller  shall  deliver to Buyer,  at  Seller's  expense,  an
          as-built  survey  of  the  Real  Property   meeting  the  requirements
          described in Section 5.5 and showing no material encroachments,  bases
          for third-party  claims or violations of law or private  covenants not

                                      LEASE



     THIS LEASE,  made as of the date specified in the Basic Lease  Information,
by  and  between  the  landlord   specified  in  the  Basic  Lease   Information
("Landlord"),   and  the  tenant  specified  in  the  Basic  Lease   Information
("Tenant"),


                              W I T N E S S E T H:


                                    ARTICLE 1

                                    Premises

     1.1  Landlord  hereby  leases to Tenant,  and  Tenant  hereby  leases  from
Landlord,  for the term and subject to the covenants  hereinafter  set forth, to
all of which  Landlord and Tenant  hereby  agree,  the  building  located at the
address  specified in the Basic Lease  Information (the  "Building")  containing
approximately  239,749  rentable square feet of space, and the land on which the
Building  is  located  (such  land,  together  with the  Building  and the other
improvements thereon are referred to herein, collectively, as the "Premises").


                                    ARTICLE 2

                                      Term

     2.1 The term of this Lease shall be the term  specified  in the Basic Lease
Information,  which shall  commence on the  commencement  date  specified in the
Basic Lease Information (the "Commencement  Date") and, unless sooner terminated
as hereinafter provided, shall end on the expiration date specified in the Basic
Lease Information (the "Expiration Date").

     2.2 If the  Commencement  Date is not the  first day of a  calendar  month,
Tenant shall pay to Landlord,  as additional  rent,  the Base Rent payable under
section  3.1,  calculated  on  a  per  diem  basis,  for  the  period  from  the
Commencement  Date until the first day of the next full calendar  month.  Tenant
shall  pay  the  Base  Rent  in  respect  of  such  period  to  Landlord  on the
Commencement Date.

     2.3 Tenant  shall accept the  Premises  "as is" on the  Commencement  Date.
Landlord  shall have no obligation to construct or install any  improvements  in
the Premises.  Tenant  acknowledges that, prior to the Commencement Date, Tenant
occupied the  Premises.  Tenant's  possession of the Premises  shall  constitute
Tenant's  acknowledgment  that the Premises are in all respects in the condition
in which Landlord is required to deliver the Premises to Tenant under this Lease
and that Tenant has  examined  the  Premises  and is fully  informed to Tenant's
satisfaction of the physical and environmental  condition and the utility of the
Premises.  Tenant acknowledges that Landlord, its agents and employees and other
persons acting on behalf of Landlord have made no  representation or warranty of
any kind in connection with any matter relating to the physical or environmental
condition,  value,  fitness, use or zoning of the Premises upon which Tenant has
relied directly or indirectly for any purpose.

                                       2


     2.4 Provided that Tenant is not in monetary or other material default under
or breach of this Lease,  either at the time of exercising the applicable option
to renew  described  below or at the time such  renewal term  commences,  Tenant
shall have the option to renew  this Lease for two (2)  additional  terms of ten
(10) years each.  Tenant shall  exercise  each option to renew by  delivering to
Landlord written notice of Tenant's  election to renew the term of this Lease at
least  eighteen (18) months before the expiration of the  then-existing  term of
this Lease.  Landlord's failure to receive Tenant's written notice duly electing
to renew the term of this Lease shall be conclusively  deemed Tenant's  election
not to exercise its option to renew, in which event the term shall expire on the
last day of the then-existing term. If Tenant duly exercises an option to renew,
then  Tenant  shall  continue  to occupy  the  Premises  on all of the terms and
conditions  of this  Lease,  except  that:  (a) the Base Rent  payable by Tenant
during the  applicable  renewal  term shall be increased as set forth in section
3.1(a);  and (b) after the second  renewal  term,  Tenant  shall have no further
renewal  options  under this Lease.  Tenant's  rights to extend the term of this
Lease are  personal  to Tenant,  may not be  exercised  by or be assigned to any
person or entity  other than  Tenant or a  Corporate  Successor  (as  defined in
section  12.1),  and  shall  terminate  and be of no  further  effect  upon  any
assignment of this Lease or subletting of all or any part of the Premises to any
person or entity.


                                    ARTICLE 3

                                      Rent

     3.1 Tenant shall pay to Landlord the following amounts as base monthly rent
for the Premises ("Base Rent"):

     (a) During the period between the Commencement Date and the last day of the
twelfth full calendar month thereafter,  Tenant shall pay to Landlord the amount
of monthly rent  specified in the Basic Lease  Information  (the  "Initial  Base
Rent").  Commencing on the first day of the thirteenth full calendar month after
the  Commencement  Date,  and on  each  anniversary  of  that  date  thereafter,
including during all renewal terms (each, an "Adjustment  Date"),  the Base Rent
shall be increased to an amount equal to the greater of:

          (i)  the  sum  of (A)  the  Base  Rent  in  effect  during  the  month
     immediately  preceding the Adjustment Date, plus (B) the product of (1) the
     Base Rent in effect during the month  immediately  preceding the Adjustment
     Date, multiplied by (2) the lesser of (x) three percent (3.0%), and (y) the
     product of two (2),  multiplied by the percentage  increase in the Consumer
     Price Index (as defined  below)  measured from the last month for which the
     Consumer  Price Index is published  immediately  preceding  the date twelve
     (12) months prior to the Adjustment  Date in question to the last month for
     which the Consumer Price Index is published  immediately  preceding the CPI
     Adjustment Date in question; and
<PAGE>
                                       3


          (ii) the  lesser  of (A) the  Initial  Base  Rent  increased  by three
     percent  (3%)  per  year,  compounded,  from the  Commencement  Date to the
     Adjustment Date in question,  and (B) the sum of (1) an amount equal to the
     Initial  Base  Rent,  plus (2) the  product  of (x) an amount  equal to the
     Initial Base Rent,  multiplied by (y) the product of two (2), multiplied by
     the percentage  increase in the Consumer Price Index measured from the last
     month for which the Consumer Price Index is published immediately preceding
     the Commencement  Date to the last month for which the Consumer Price Index
     is published immediately preceding the Adjustment Date in question;

provided,  however,  that in no event  shall the Base Rent after any  Adjustment
Date be less than the product of an amount  equal to the Base Rent in effect for
the month immediately  preceding such Adjustment Date, multiplied by one hundred
one and one-half percent (101.5%).

     (b) Landlord and Tenant each shall, promptly after any determination of the
Base Rent pursuant to section 3.1(a), execute and deliver to the other a written
confirmation  which sets forth the Base  Rent,  but such Base Rent shall  become
effective whether or not such confirmation is executed.

     (c) As used in this Lease,  "Consumer  Price Index" shall mean the Consumer
Price Index for All Cities,  All Urban  Consumers,  All Items,  1982-1984 equals
100,  published  by the  United  States  Department  of  Labor,  Bureau of Labor
Statistics.  If the comparison Consumer Price Index required for the calculation
specified in section 3.1(a) is not available on the Adjustment Date in question,
Tenant  shall to pay, as of such  Adjustment  Date,  one hundred  three  percent
(103%) of the Base Rent payable  during the period  immediately  preceding  such
Adjustment  Date until the Consumer  Price Index is available  and the necessary
calculation  is  made.  As  soon as  such  calculation  is  made,  Tenant  shall
immediately pay to Landlord or Landlord shall credit Tenant (as the case may be)
the  amount of any  underpayment  or  overpayment  of Base Rent for the month or
months that may have elapsed  pending the  calculation  of the Base Rent for the
Adjustment  Date in  question.  If the federal  government  revises or ceases to
publish the  Consumer  Price  Index,  this  section 3.1 shall  automatically  be
amended to provide that, as of each  Adjustment Date  thereafter,  the Base Rent
shall be one hundred  three percent  (103%) of the Base Rent payable  during the
period immediately preceding such Adjustment Date.

                                       4


     (d)  Throughout  the term of this Lease,  Tenant  shall pay, as  additional
rent,  all Other Taxes (as defined in section 5.3),  all Operating  Expenses (as
defined in section 5.1) and all other  amounts of money and charges  required to
be paid by Tenant  under this  Lease,  whether  or not such  amounts of money or
charges are designated  "additional  rent." As used in this Lease,  "rent" shall
mean and  include  all Base  Rent and  additional  rent  payable  by  Tenant  in
accordance with this Lease.

     3.2 It is the  intention  of Landlord and Tenant that the Base Rent payable
by Tenant to Landlord  during the entire term of this Lease shall be  absolutely
net of all  costs and  expenses  incurred  in  connection  with the  management,
operation,  maintenance,  repair and  replacement  of the Premises in accordance
with this Lease,  except as expressly  provided in section 8.3.  Landlord  shall
have no  obligations  or  liabilities  whatsoever  with respect to the costs and
expenses of  management,  operation,  maintenance,  repair or replacement of the
Premises during the term of this Lease,  except as expressly provided in section
8.3,  and  Tenant  shall pay all  costs  and  expenses  incurred  in  connection
therewith.  Without  limiting the  generality of the  foregoing,  throughout the
entire term of this Lease,  Tenant shall pay, as additional  rent, all Operating
Expenses (as defined in section 5.1) that accrue  during or are allocable to the
term of this Lease.

     3.3 Tenant  shall pay all Base Rent to Landlord,  in advance,  on or before
the first day of each and every  calendar  month  during the term of this Lease.
Tenant shall pay all additional  rent upon demand.  Tenant shall pay all rent to
Landlord  without notice,  demand,  deduction or offset,  in lawful money of the
United  States of America,  at the address of  Landlord  specified  in the Basic
Lease  Information,  or to such other  person or at such other place as Landlord
may from time to time designate in writing.

     3.4 Tenant acknowledges that the late payment by Tenant of any Base Rent or
additional  rent  (including  the items  described  in  section  3.2) will cause
Landlord to incur costs and  expenses,  the exact  amount of which is  extremely
difficult  and  impractical  to  fix.  Such  costs  and  expenses  will  include
administration  and collection  costs and  processing  and accounting  expenses.
Therefore,  if any Base Rent or  additional  rent is not  received  by  Landlord
within five (5) Business Days (as defined  below) after it is due,  Tenant shall
immediately  pay to  Landlord a late charge  equal to six  percent  (6%) of such
delinquent  amount. The term "Business Days" means any day other than Saturdays,
Sundays  and  days on  which  national  banks  are  permitted  to be  closed  in
accordance with Federal banking laws and regulations.  Landlord and Tenant agree
that such  late  charge  represents  a  reasonable  estimate  of such  costs and
expenses and is fair  compensation to Landlord for the loss suffered by Tenant's
failure to make timely payment.  In no event shall such late charge be deemed to
grant to Tenant a grace period or extension of time within which to pay any rent
or prevent  Landlord from exercising any right or enforcing any remedy available
to  Landlord  upon  Tenant's  failure  to pay all rent due under this Lease in a
timely  fashion,  including  the right to terminate  this Lease.  All amounts of
money payable by Tenant to Landlord hereunder,  if not paid when due, shall bear
interest from the due date until paid at a rate (the "Interest  Rate") per annum
equal to five (5)  percentage  points plus the prime or reference rate announced
from time to time by Bank of America N.T.&S.A.  (the "Reference Rate"), provided
that the Interest Rate shall at no time exceed twelve percent (12%) per annum.

                          Payment of Operating Expenses

     4.1(a) In addition to the Base Rent payable  during the term of this Lease,
Tenant  shall pay to  Landlord,  as  additional  rent,  an  amount  equal to the
Operating Expenses paid or incurred by Landlord in any calendar year (or partial
year)  during  the term of this  Lease.  If it shall not be lawful for Tenant to
reimburse Landlord for any Operating Expenses,  as defined herein, the Base Rent
payable to Landlord  shall be  increased  to net Landlord the same net Base Rent
after payment of such Operating Expenses as would have been received by Landlord
prior to the payment of such Operating Expenses.

     (b)  During  December  of  each  calendar  year or as  soon  thereafter  as
practicable,  Landlord  shall give Tenant  notice of its estimate of the amounts
payable pursuant to section 4.1(a) above for the succeeding calendar year. On or
before the first day of each month during the succeeding  calendar year,  Tenant
shall pay to Landlord,  as additional rent, one twelfth (1/12) of such estimated
amounts. If Landlord fails to deliver such notice to Tenant in December,  Tenant
shall  continue  to pay  Operating  Expenses  on the basis of the  prior  year's
estimate  until the first day of the next  calendar  month  after such notice is
given,  provided  that on such date Tenant  shall pay to Landlord  the amount of
such estimated  adjustment  payable to Landlord for prior months during the year
in question,  less any portion thereof previously paid by Tenant. If at any time
it appears to Landlord that the amounts  payable  under this section  4.1(b) for
the current calendar year will vary from Landlord's  estimate,  Landlord may, by
giving written notice to Tenant,  revise Landlord's  estimate for such year, and
subsequent  payments  by  Tenant  for such year  shall be based on such  revised
estimate.

     (c)(i)  Within ninety (90) days after the close of each calendar year or as
soon after such ninety (90) day period as practicable, Landlord shall deliver to
Tenant a statement of the amounts  payable under  section  4.1(a) above for such
calendar year (the "annual  statement")  and such  statement  shall be final and
binding upon Landlord and Tenant, subject to the terms of section 4.1(c)(ii). If
on the  basis of such  statement  Tenant  owes an  amount  that is more than the
estimated  payments for such calendar  year  previously  made by Tenant,  Tenant
shall pay the deficiency to Landlord  within fifteen (15) days after delivery of
the statement.  If on the basis of such statement Tenant has paid to Landlord an
amount in excess of the  amounts  payable  under  section  4.1(a)  above for the
preceding  calendar year and Tenant is not in default in the  performance of any
of its covenants under this Lease,  then Landlord,  at its option,  shall either
promptly  refund such excess to Tenant or credit the amount  thereof to the Base
Rent next becoming due from Tenant until such credit has been exhausted.
<PAGE>
                                       6


     (ii) Tenant shall have the right,  during the one hundred  eighty (180) day
period  following  delivery of an annual  statement,  at  Tenant's  sole cost to
review in Landlord's  offices  Landlord's records of Operating Expenses and Real
Property Taxes for the subject  calendar year.  Such review shall be carried out
only by regular employees of Tenant or by a "Big Six" accounting firm and not by
any other third party.  No person  conducting such an audit shall be compensated
on a "contingency" or other incentive basis. If, as of the one hundred eightieth
day after  delivery  to Tenant of an  annual  statement,  Tenant  shall not have
delivered  to Landlord an  objection  statement  (as defined  below),  then such
annual statement shall be final and binding upon Landlord and Tenant, and Tenant
shall have no further right to object to such annual  statement.  If within such
one  hundred  eighty  (180) day  period,  Tenant  delivers to Landlord a written
statement  specifying   objections  to  such  annual  statement  (an  "objection
statement"),  then  Tenant and  Landlord  shall meet to attempt to resolve  such
objection within thirty (30) days after delivery of the objection statement.  If
such objection is not resolved  within such thirty (30) day period,  then either
party shall have the right to require  that the dispute be  submitted to binding
arbitration   under  the  rules  of  the   American   Arbitration   Association.
Notwithstanding  that any  such  dispute  remains  unresolved,  Tenant  shall be
obligated to pay Landlord all amounts  payable in  accordance  with this section
4.1 (including any disputed amount).  If such dispute results in an agreement or
an  arbitrator's  determination  that Tenant is  entitled to a refund,  Landlord
shall, at its option, either pay such refund or credit the amount thereof to the
Base Rent next becoming due from Tenant.

     (d) If this Lease terminates on a day other than the last day of a calendar
year,  the amounts  payable by Tenant under section 4.1(a) above with respect to
the  calendar  year in which such  termination  occurs  shall be prorated on the
basis which the number of days from the  commencement  of such calendar year, to
and including such termination date, bears to 360. The termination of this Lease
shall not affect the  obligations  of  Landlord  and Tenant  pursuant to section
4.1(c) above to be performed after such termination.

expensive by a reasonable owner of a comparable  building,  Landlord shall first
have obtained Tenant's reasonable approval) or that are designed to reduce other
Operating Expenses,  such cost or allocable portion thereof to be amortized over
the useful life  thereof  (except  that  Landlord  may  include as an  Operating
Expense in any calendar year a portion of the cost of such a capital improvement

     5.4 In the event that  Tenant  reasonably  and in good faith  disputes  the
validity or amount of any Property Taxes or Other Taxes,  then Tenant shall have
the right to defer  payment  thereof,  provided that (a) Tenant shall have given
Landlord  written notice of such contest and the nature thereof and Tenant shall
thereafter  diligently and continuously  prosecute such contest to completion or

                                       Use

     6.1 The Premises shall be used only for the purpose  specified in the Basic
Lease Information and no other purpose without Landlord's prior written consent,
which consent shall not be unreasonably withheld or delayed; provided,  however,
Landlord's  withholding of consent shall be conclusively  presumed reasonable if
the proposed use would  materially  increase the wear and tear on or the risk of
damage to the Premises above levels or risks  resulting from Tenant's use of the
Premises  exclusively  for  office  purposes  or if the  proposed  use is for an
illegal,  immoral or disreputable purpose; and provided,  further, that only the
Tenant originally named herein, and no subtenant, assignee or other successor to
such  original  Tenant,  shall  have the right to use the  Premises  or any part
thereof for any purpose other than office use.  Notwithstanding  anything to the
contrary in the Basic Lease Information,  (a) Tenant's right to use the Premises
or any part  thereof for any use other than  general  office use (whether or not
such  other use is listed in the Basic  Lease  Information)  is  subject  to the
following conditions:  (i) such ancillary  (non-office) uses shall be limited to
areas  comprising  less than thirty percent (30%) of the total  rentable  square
footage  of the  building  in the  aggregate,  and (ii) all such  uses  shall be
consistent with Tenant's  obligations  under Articles 11 and 21 hereof;  and (b)
any  subtenant  or assignee of the  original  Tenant  named herein shall use the
Premises  exclusively  for office  purposes and no other use shall be permitted,
except that the  original  Tenant  named herein may sublease the portions of the
Premises  to be used as an  employee  cafeteria  or  child  care  center  to the
operators of those  facilities.  Tenant shall not do or permit to be done in, on
or about  the  Premises,  nor  bring or keep or  permit  to be  brought  or kept
therein,  anything  which is  prohibited by or will in any way conflict with any
law, ordinance, rule, regulation or order now in force or which may hereafter be
enacted,  or which is prohibited by any  insurance  policy for the Premises,  or
will in any way increase the existing  rate of, or cause a  cancellation  of, or
affect any insurance for the Premises. Tenant shall not do or permit anything to
be done in, on or about the Premises which will in any way obstruct or interfere
with the rights of  Landlord.  Tenant  shall not maintain or permit any nuisance
in, on or about the Premises or commit or suffer to be  committed  any waste in,
on or about the Premises.

shall not be in default  hereunder or be liable for any damage or loss  directly
or indirectly  resulting from, nor shall the rent be abated or a constructive or
other eviction be deemed to have occurred by reason of, the installation, use or
interruption of use of any equipment in connection with the furnishing of any of
the foregoing  services,  any failure to furnish or delay in furnishing any such
services,  whether such failure or delay is caused by accident or any  condition
beyond  the  control  of  Landlord  or Tenant or by the  making  of  repairs  or
improvements  to the  Premises,  or any  limitation,  curtailment,  rationing or
restriction on use of water, electricity,  gas or any form of energy serving the
Premises,  whether such  results  from  mandatory  governmental  restriction  or
voluntary  compliance with  governmental  guidelines.  Tenant shall pay the full
cost of all of the  foregoing  services as additional  rent in  accordance  with
Article 4.

                  Maintenance and Repairs; Capital Improvements

     8.1  Landlord  shall,  at all times  during  the term of this  Lease and at
Tenant's  sole cost and expense  (except as otherwise  provided in section 8.3),
maintain,  repair  and  replace  the  Premises  and every part  thereof  and all
grounds, landscaping, parking areas, lighting, roof, walls, floors, foundations,

plumbing, sprinkler and life safety systems, equipment,  fixtures,  alterations,
additions  and  improvements  therein or thereon  and keep all of the  foregoing
clean and in good order and operating condition (including painting the exterior
of the Premises as often as  reasonably  needed to keep such exterior in a good,
well painted condition, cleaning interior and exterior doors, windows and glass,
and  repairing  and  replacing  any  exterior  windows and glass that is broken,
cracked  or  damaged).   Landlord  shall  engage  a  duly  licensed  independent
contractor  to perform  all  maintenance  and repair  services  on all  heating,
ventilating and air conditioning,  mechanical,  electrical,  plumbing, sprinkler
and life safety systems and equipment in the Premises that is to be performed by
Landlord in accordance with this section 8.1. Tenant hereby waives all rights to

Premises.  Subject to section 9.2,  Tenant shall, at the end of the term of this
Lease,  surrender  to Landlord  the  Premises  and all  alterations,  additions,
fixtures  and  improvements  therein or thereto  in the same  condition  as when
received,  ordinary wear and tear and damage  thereto by fire or other  casualty
excepted.

     8.2 In the event  Landlord  fails to  perform  any  maintenance  and repair
obligation  under section 8.1 within fifteen (15) days after Tenant  delivers to
Landlord  notice  specifying  such  obligation  (or such longer period as may be
reasonably required due to the nature of such obligation), then Tenant may, upon
a further ten (10) days'  notice to  Landlord,  perform at Tenant's  own expense
such obligation  (unless  Landlord cures its  nonperformance  within such 10-day
period).  Notwithstanding  the foregoing,  in the event that (a)  maintenance or
repairs  are,  in  Tenant's  reasonable  judgment,  urgently  required  to avoid
material  disruption of or interference  with the operation of Tenant's business
on the  Premises  or to avoid  imminent  danger  to health  or  safety,  and (b)
Landlord,  having  received  notice  thereof,  does not, in Tenant's  reasonable
judgment,  commence  with  appropriate  promptness  and pursue with  appropriate
diligence  the  required  maintenance  or repairs,  then Tenant may perform such
maintenance  or repairs  without  waiting for the time  periods set forth in the
preceding sentence.

     8.3 To the extent included within the definition of "Operating Expenses" in
section 5.1, the costs incurred by Landlord in performing its obligations  under
section  8.1 shall be  recoverable  from  Tenant  pursuant  to Article 4. To the
extent such costs are excluded from the definition of "Operating Expenses," such
costs shall be Landlord's responsibility, subject to Landlord's right to collect
reserves for  anticipated  capital  repairs,  improvements  and  replacements in
accordance  with the definition of "Operating  Expenses".  In the event that the
cost of any such  capital  repairs,  improvements  or  replacements  exceeds the
amount that Landlord has specified to be reserved therefor,  Landlord shall bear
such cost to the extent of such excess.

                                    ARTICLE 9

                                   Alterations

     9.1 Tenant shall not make any alterations,  additions or improvements in or
to the  Premises  or any part  thereof,  or attach  any  fixtures  or  equipment
thereto,  without  Landlord's prior written consent,  which consent shall not be
unreasonably withheld.  Notwithstanding the preceding sentence,  Tenant may make
such alterations,  additions or improvements  without Landlord's consent only if
the total cost of such alterations,  additions or improvements is fifty thousand
dollars ($50,000) or less and such  alterations,  additions or improvements will
not affect in any way the structural,  exterior or roof elements of the Premises
or  mechanical,  electrical,  plumbing,  utility or life  safety  systems of the
Premises,  but Tenant shall give prior written  notice of any such  alterations,
additions or improvements to Landlord.  In no event shall Tenant be permitted to
install  underground storage tanks (excepting a single 20,000 gallon water tank)
or  fuel  systems  on  the  Premises.  Landlord's  refusal  to  consent  to  the
installation  of an  underground  tank  or fuel  system  shall  be  conclusively
presumed to be reasonable. All alterations,  additions and improvements in or to
the Premises to which Landlord consents shall be made by Tenant at Tenant's sole
cost and expense as follows:

     (a) Tenant shall  submit to  Landlord,  for  Landlord's  written  approval,
complete plans and specifications for all work to be done by Tenant.  Such plans
and  specifications   shall  be  prepared  by  the  licensed   architect(s)  and
engineer(s), shall comply with all applicable codes, laws, ordinances, rules and
regulations, shall not adversely affect the structural elements of the Premises,
shall  be in a  form  sufficient  to  secure  the  approval  of  all  government
authorities  with  jurisdiction  over  the  Premises,  and  shall  be  otherwise
satisfactory to Landlord in Landlord's reasonable discretion.

     (b) Landlord  shall notify Tenant in writing,  within fifteen (15) Business
Days after Landlord's receipt of such plans and specifications, whether Landlord
approves  or  disapproves  such  plans  and  specifications   and,  if  Landlord
disapproves such plans and  specifications,  Landlord shall describe the reasons
for disapproval.  Tenant may submit to Landlord revised plans and specifications
for Landlord's prior written approval. Tenant shall pay all costs, including the
fees and expenses of the licensed  architect(s)  and  engineer(s),  in preparing
such plans and specifications.
<PAGE>
                                       15


     (c) All changes in the plans and specifications  approved by Landlord shall
be subject to Landlord's  prior written  approval.  If Tenant wishes to make any
such change in such approved  plans and  specifications,  Tenant shall have such
architect(s) and engineer(s)  prepare plans and  specifications  for such change
and submit them to Landlord for  Landlord's  written  approval.  Landlord  shall
notify Tenant in writing promptly whether Landlord  approves or disapproves such
change and, if Landlord  disapproves  such change,  Landlord  shall describe the
reasons  for  disapproval.  Tenant  may  submit to  Landlord  revised  plans and
specifications for such change for Landlord's written approval. After Landlord's
written approval of such change,  such change shall become part of the plans and
specifications approved by Landlord.

     (d) Tenant  shall  obtain and comply  with all  building  permits and other
governmental  permits and approvals required in connection with the work. Tenant
shall, through Tenant's licensed  contractor,  perform the work substantially in
accordance  with  (i) the  plans  and  specifications  approved  in  writing  by
Landlord,  (ii) the permits obtained by Tenant,  and (iii) all applicable codes,
laws, ordinances,  rules and regulations.  Tenant shall pay, as additional rent,
the entire cost of all work (including the cost of all utilities, permits, fees,
taxes, and property and liability  insurance  premiums in connection  therewith)
required  to  make  the  alterations,   additions  and  improvements.  Under  no
circumstances  shall Landlord be liable to Tenant for any damage,  loss, cost or
expense  incurred  by  Tenant  on  account  of  any  plans  and  specifications,
contractors or subcontractors,  design of any work, construction of any work, or
delay in completion of any work.

     (e)  Tenant  shall give  written  notice to  Landlord  of the date on which
construction  of any work will be commenced at least ten (10) days prior to such
date. Tenant shall keep the Premises free from mechanics', materialmen's and all
other  liens  arising  out of any  work  performed,  labor  supplied,  materials
furnished or other  obligations  incurred by Tenant.  Tenant shall  promptly and
fully pay and  discharge all claims on which any such lien could be based or, in
the event Tenant  reasonably  disputes the validity or amount of any such claim,
Tenant may bond over such lien to Landlord's reasonable  satisfaction.  Landlord
shall have the right to post and keep posted on the  Premises  any notices  that
may be  provided  by law or  which  Landlord  may  deem  to be  proper  for  the
protection of Landlord and the Premises  from such liens,  and to take any other
action  Landlord deems necessary to remove or discharge liens or encumbrances at
the expense of Tenant.

     9.2  All  alterations,   additions,  fixtures  and  improvements,   whether
temporary or permanent in  character,  made in or to the Premises by Landlord or
Tenant,  shall become part of the Premises and  Landlord's  property  excluding,
however,  underground  tanks which shall remain the property of Tenant and shall
be  registered  in the name of Tenant so long as this  Lease  remains in effect.
Upon  termination of this Lease,  Landlord  shall have the right,  at Landlord's
option, by giving written notice to Tenant at any time before or within ten (10)
days after such termination, to retain all such alterations, additions, fixtures
and improvements in the Premises,  without  compensation to Tenant, or to remove
all such  alterations,  additions,  fixtures and improvements from the Premises,
repair all damage  caused by any such  removal,  and restore the Premises to the
<PAGE>
                                       16


condition  in which the Premises  existed  before such  alterations,  additions,
fixtures and improvements  were made, and in the latter case Tenant shall pay to
Landlord,  upon  billing  by  Landlord,  the cost of such  removal,  repair  and
restoration   (including  a  reasonable  charge  for  Landlord's  oversight  and
administration  of  such  work).  Notwithstanding  the  foregoing,  all  movable
furniture,  equipment,  trade fixtures (including the video screen walls, visual
systems,  projectors  and  related  equipment  in Tenant's  service  reliability
center) and other personal  property  shall remain the property of Tenant.  Upon
termination of this Lease,  Tenant shall, at Tenant's  expense,  remove all such
movable  furniture,  equipment,  trade fixtures other personal property from the
Premises and repair all damage caused by any such removal.  Termination  of this
Lease shall not affect the obligations of Tenant pursuant to this section 9.2 to
be performed after such termination.

                                    Insurance

     10.1  Landlord  shall not be liable to Tenant  for any damage to or loss or
theft of any property or for any bodily or personal injury,  illness or death of
any person in, on or about the  Premises  arising at any time and from any cause
whatsoever,  except to the  extent  caused by the gross  negligence  or  willful
misconduct of Landlord.  Tenant waives all claims against  Landlord arising from
any liability described in this section 10.1, except to the extent caused by the
gross negligence or willful misconduct of Landlord.

     10.2 Tenant shall indemnify and defend  Landlord  against and hold Landlord
harmless  from all claims,  demands,  liabilities,  damages,  losses,  costs and
expenses,  including reasonable attorneys' fees and disbursements,  arising from
or related to any use or  occupancy  of the  Premises,  or any  condition of the
Premises,  or any default in the  performance  of Tenant's  obligations,  or any
damage to any property  (including property of employees and invitees of Tenant)
or any bodily or  personal  injury,  illness  or death of any person  (including
employees and invitees of Tenant)  occurring in, on or about the Premises or any
part  thereof or any part of the  building or the land  containing  the Premises
arising at any time and from any cause  whatsoever  (except to the extent caused
by the gross negligence or willful  misconduct of Landlord) or occurring outside
the Premises when such damage,  bodily or personal  injury,  illness or death is
caused by any act or  omission  of Tenant or its  agents,  officers,  employees,
contractors,  invitees  or  licensees.  This  section  10.2  shall  survive  the
termination of this Lease with respect to any damage, bodily or personal injury,
illness or death occurring prior to such termination.

     10.3  Tenant  shall,  at all  times  during  the term of this  Lease and at
Tenant's  sole cost and  expense,  obtain and keep in force  commercial  general
liability insurance, including contractual liability (specifically covering this
Lease), cross liability,  fire legal liability, and premises operations,  all on
an "occurrence"  policy form, with a minimum combined single limit in the amount
specified in the Basic Lease  Information  per occurrence for bodily or personal
injury to, illness of, or death of persons and damage to property  occurring in,
on or about the Premises,  such insurance  shall name the Landlord and any other
parties designated by Landlord,  or any other party with an insurable  interest,
as  additional  insureds.  Tenant shall,  at Tenant's sole cost and expense,  be
responsible for insuring Tenant's  furniture,  equipment,  fixtures,  computers,
office machines and personal property.

     10.4  Tenant  shall,  at all  times  during  the term of this  Lease and at
Tenant's sole cost and expense,  obtain and keep in force worker's  compensation
and employer's  liability  insurance in all states in which the Premises and any
other  operations  of the Tenant are  located  and any other  state in which the
Tenant or its contractors or  subcontractors  may be subject to any statutory or
other  liability  arising in any manner  whatsoever out of the actual or alleged
employment  of others.  The total limits of the  employer's  liability  coverage
required hereunder shall not be less than the amounts specified in section 10.3.

     10.5 The insuring party for property insurance specified in the Basic Lease
Information  shall,  at all times during the term of this Lease, at such party's
sole cost and expense,  obtain and keep in force (a)  insurance  against loss or
damage to the  Premises by fire and all other risks of physical  loss covered by
insurance  of the type now known as "all risk," with  difference  in  conditions
coverage,  in an amount not less than the full  replacement cost of the Premises
(without deduction for depreciation),  including the cost of debris removal, and
such endorsements as Landlord may reasonably require, including the "Replacement
Cost Endorsement"; (b) boiler and machinery insurance covering pressure vessels,
air tanks, boilers,  machinery,  pressure piping,  heating,  ventilation and air
conditioning  equipment,  and elevator  and  escalator  equipment,  provided the
Premises  contain  equipment  of  such  nature  and  insurance  against  loss of
occupancy or use arising from any  breakdown of any such items,  in such amounts
as Landlord  may  reasonably  determine;  and (c) plate glass  insurance in such
amounts as Landlord  may  reasonably  determine if the  Premises  contain  plate
glass. In addition to the insurance  specifically  described above, Tenant shall
obtain and keep in force such other insurance (or the above-described  insurance
at increased limits) as Landlord may reasonably require from time to time.

     10.6 All  insurance  required to be maintained by Tenant under this Article
10 and all renewals  thereof shall be issued by good and  responsible  companies
qualified  to do and doing  business in the state where the Premises are located
and having a rating in Best's  Insurance  Guide of at least A-XI. All deductible
amounts under each such  insurance  policy shall be subject to Landlord's  prior

<PAGE>
                                       18


written approval. Each policy to be maintained by Tenant shall expressly provide
that the policy shall not be canceled or altered  without sixty (60) days' prior
written notice to Landlord and shall remain in effect  notwithstanding  any such
cancellation  or alteration  until such notice shall have been given to Landlord
and such period of sixty (60) days shall have expired.  All insurance under this
Article 10 to be  maintained by Tenant shall name Landlord and any other parties
designated  by Landlord,  or any other party with an insurable  interest,  as an
additional insured or loss payee, shall be primary and noncontributing  with any
insurance which may be carried by Landlord, shall afford coverage for all claims
based on any act,  omission,  event or condition  that occurred or arose (or the
onset of which occurred or arose) during the policy period,  and shall expressly
provide  that  Landlord,   although  named  as  an  additional  insured,   shall
nevertheless  be  entitled to recover  under the policy for any loss,  injury or
damage to Landlord.  Upon the issuance of each such policy to be  maintained  by
Tenant,  Tenant  shall  deliver  each  such  policy  or a  certified  copy and a
certificate  thereof to Landlord for  retention by Landlord.  If Tenant fails to
insure or fails to furnish  to  Landlord  upon  notice to do so any policy to be
maintained  by Tenant or  certified  copy and  certificate  thereof as required,
Landlord shall have the right from time to time to effect such insurance for the
benefit of Tenant or Landlord or both of them and all premiums  paid by Landlord
shall be payable by Tenant as  additional  rent on demand.  Tenant  shall pay to
Landlord,  immediately upon demand all costs incurred by Landlord as a result of
Tenant's  failure to obtain and  maintain in effect the  policies  of  insurance
required under this Article 10.

     10.7  Tenant  waives on  behalf  of all  insurers  under  all  policies  of
property, liability and other insurance (excluding workers' compensation) now or
hereafter carried by Tenant insuring or covering the Premises, or any portion or
any contents thereof, or any operations therein, all rights of subrogation which
any insurer might  otherwise,  if at all,  have to any claims of Tenant  against
Landlord.  Landlord  waives on  behalf of all  insurers  under all  policies  of
property, liability and other insurance (excluding workers' compensation) now or
hereafter  carried by Landlord  insuring or covering the Premises or any portion
or any contents thereof,  or any operations  therein,  all rights of subrogation
which any insurer  might  otherwise,  if at all,  have to any claims of Landlord
against  Tenant.  Tenant shall,  prior to or immediately  after the date of this
Lease,  procure  from each of the  insurers  under  all  policies  of  property,
liability and other insurance (excluding workers' compensation) now or hereafter
carried by Tenant  insuring  or  covering  the  Premises,  or any portion or any
contents  thereof,  or  any  operations  therein,  a  waiver  of all  rights  of
subrogation which the insurer might otherwise,  if at all, have to any claims of
Tenant against Landlord as required by this section 10.6.

                       Compliance With Legal Requirements

     11.1 Tenant shall, at Tenant's sole cost and expense,  promptly comply with
all of the following  (collectively,  "Legal  Requirements")  laws,  ordinances,
rules,  regulations,  orders and other  requirements of any government or public
authority now in force or which may hereafter be in force, with all requirements
of any  board of fire  underwriters  or  other  similar  body  now or  hereafter
constituted,  with all directions and  certificates of occupancy issued pursuant
to any  law by  any  governmental  agency  or  officer  and  with  all  recorded
covenants,  conditions or restrictions,  insofar as any thereof relate to or are
required by the  condition,  use or occupancy of the Premises or the  operation,
use or maintenance of any personal property, fixtures,  machinery,  equipment or
improvements in the Premises. Tenant's obligations under this section 11.1 shall
include the obligation to make  alterations or  improvements  to the Premises if
required to comply with any Legal Requirements.

                                   ARTICLE 12

                             Assignment or Sublease

     12.1 Tenant shall not,  directly or  indirectly,  without the prior written
consent of Landlord (which consent shall not be unreasonably  withheld),  assign
this Lease or any interest  herein or sublease the Premises or any part thereof,
or permit the use or  occupancy  of the  Premises by any person or entity  other
than Tenant;  provided,  however,  Landlord's  withholding  of consent  shall be
conclusively presumed reasonable if: (a) the financial condition of the proposed
transferee  is not  suitable  to perform  the  obligations  being  assumed by it
hereunder;  or  (b)  the  proposed  use  of the  Premises  (i) is not  permitted
hereunder  or under any Legal  Requirements,  or (ii) is other  than  office use
(except in the case of a sublease of the portions of the Premises to be used for
an  employee  cafeteria  and  child  care  center  to  the  operators  of  those
facilities).  This Lease shall not, nor shall any interest herein, be assignable
as to the  interest of Tenant  involuntarily  or by operation of law without the
prior written consent of Landlord.  Any of the foregoing acts without such prior
written  consent of Landlord shall be void and shall, at the option of Landlord,
constitute  a  default  that   entitles   Landlord  to  terminate   this  Lease.
Notwithstanding  the  foregoing,  Landlord  hereby  consents to any  sublease or
assignment to any direct or indirect wholly-owned subsidiary of either Tenant or
ICG Communications, Inc., a Delaware corporation or to any surviving corporation
resulting  from a  merger  with  Tenant,  or to any  corporation  as part of the
acquisition  of all or  substantially  all of the assets and  business of Tenant
(collectively,  a "Corporate  Successor"),  provided such sublease or assignment
otherwise complies with this Article 12, and provided further that Landlord does
not  approve any such  sublease or  assignment  in  connection  with a merger or
acquisition if the net worth or  creditworthiness  of such subtenant or assignee
is, in Landlord's  reasonable  judgment,  less than that of Tenant prior to such
merger or  acquisition  transaction.  Tenant agrees that the instrument by which
any  assignment or sublease to which  Landlord  consents is  accomplished  shall
expressly  provide  that the  assignee  or  subtenant  will  perform  all of the
covenants to be performed by Tenant under this Lease (in the case of a sublease,
only insofar as such covenants  relate to the portion of the Premises subject to
such  sublease) as and when  performance  is due after the effective date of the
assignment  or sublease  and that  Landlord  will have the right to enforce such
covenants directly against such assignee or subtenant.  Any purported assignment
or sublease without an instrument  containing the foregoing  provisions shall be
void.  Tenant  shall in all  cases  remain  liable  for the  performance  by any
assignee or subtenant of all such covenants.

     12.2 If Landlord  consents in writing,  Tenant may  complete  the  intended
assignment or sublease subject to the following covenants:  (a) no assignment or
sublease  shall be valid and no assignee or subtenant  shall take  possession of
the Premises or any part thereof  until an executed  duplicate  original of such
assignment or sublease,  in compliance  with section 12.1, has been delivered to
Landlord,  (b) no assignee or subtenant  shall have a right further to assign or
sublease.
<PAGE>
                                       21


     12.3 No  assignment  or  sublease  whatsoever  shall  release  Tenant  from
Tenant's  obligations  and  liabilities  under this  Lease or alter the  primary
liability  of Tenant to pay all rent and to perform all  obligations  to be paid
and  performed  by Tenant.  The  acceptance  of rent by Landlord  from any other
person or entity shall not be deemed to be a waiver by Landlord of any provision
of this Lease. Consent to one assignment or sublease shall not be deemed consent
to any  subsequent  assignment  or  sublease.  If  any  assignee,  subtenant  or
successor  of  Tenant  defaults  in  the  performance  of any  obligation  to be
performed by Tenant  under this Lease,  Landlord  may proceed  directly  against
Tenant  without the  necessity of  exhausting  remedies  against such  assignee,
subtenant  or  successor.  Landlord  may consent to  subsequent  assignments  or
subleases  or  amendments  or   modifications  to  this  Lease  with  assignees,
subtenants or successors of Tenant, without notifying Tenant or any successor of
Tenant and without obtaining any consent thereto from Tenant or any successor of
Tenant,  and such action  shall not release  Tenant  from  liability  under this
Lease.

     12.4 Upon  Tenant's  entering into any agreement to sell or transfer all or
substantially  all of its  assets  (whether  or not  the  assets  to be  sold or
transferred  include this Lease),  Tenant shall within three (3) days thereafter
notify  Landlord of the essential  terms of such  agreement.  If Tenant sells or
transfers  substantially  all of its assets but does not  expressly  assign this
Lease to the transferee,  then at Landlord's option,  this Lease shall be deemed
to have been assigned to such transferee and such transferee  shall be deemed to
have assumed all of Tenant's  obligations  under this Lease.  If such transferee
does not expressly assume such obligations in writing within ten (10) days after
demand  delivered to Tenant,  the  Stipulated  Difference (as defined in section
14.2(c)) shall be increased by five million dollars ($5,000,000).

                                Entry by Landlord

     13.1 Landlord  shall have the right,  upon not less than  twenty-four  (24)
hours prior notice (except in cases of emergency),  to enter the Premises at any
time to (a)  inspect the  Premises,  (b)  exhibit  the  Premises to  prospective
purchasers,  lenders  or  (during  the last  eighteen  (18)  months of the term)
tenants, (c) determine whether Tenant is performing all of Tenant's obligations,
(d) perform any  obligations of Tenant in accordance with section 14.5, (e) post
notices of nonresponsibility in and about the Premises,  (f) make any repairs to
the  Premises  and (g)  investigate  and  perform  tests to  determine  Tenant's
compliance  with Article 21. In connection  with any such entry,  Landlord shall
use reasonable  efforts to avoid any  unnecessary  disruption of or interference
with Tenant's business  operation.  Tenant waives all claims for damages for any
injury or inconvenience to or interference with Tenant's  business,  any loss of
occupancy or quiet  enjoyment of the  Premises or any other loss  occasioned  by
such entry.  If  Landlord  removes any  existing  underground  tanks and fueling
system from the Premises,  Landlord  shall have no obligation to replace them or
provide alternate tanks or a fueling system.  Landlord shall at all times have a
key to unlock  all such doors and  Landlord  shall have the right to use any and
all means which  Landlord  may deem proper to open such doors in an emergency to
obtain entry to the Premises.  Any entry to the Premises obtained by Landlord by
any of such means shall not under any circumstances be construed or deemed to be
a forcible or unlawful  entry into or a detainer of the Premises or an eviction,
actual or constructive, of Tenant from the Premises or any portion thereof.

                         Events of Default and Remedies

     14.1 The  occurrence of any one or more of the following  events ("Event of
Default") shall constitute a breach of this Lease by Tenant:

     (a) Tenant  fails to pay any Base Rent  within five (5) days after the date
when such rent becomes due or fails to make the additional  deposits to the Draw
Account within the time period set forth in section 24.5; or

     (b) Tenant  fails to pay any  additional  rent or other  amount of money or
charge payable by Tenant hereunder as and when such additional rent or amount or
charge becomes due and payable and such failure continues for more than ten (10)
Business Days after Landlord  gives written notice thereof to Tenant;  provided,
however, that after the second such failure in a calendar year, only the passage
of time,  but no further  notice,  shall be  required to  establish  an Event of
Default in the same calendar year; or

     (c) Tenant fails to perform or breaches any other  agreement or covenant of
this Lease to be  performed  or  observed by Tenant as and when  performance  or
observance  is due and such failure or breach  continues  for more than ten (10)
Business Days after Landlord  gives written notice thereof to Tenant;  provided,
however,  that if, by the nature of such agreement or covenant,  such failure or
breach cannot  reasonably be cured within such period of ten (10) Business Days,
an  Event of  Default  shall  not  exist as long as  Tenant  commences  with due
diligence  and dispatch the curing of such failure or breach within a reasonable
period of time after  becoming  aware of such  failure or breach and,  having so
commenced,  thereafter  prosecutes with diligence and dispatch and completes the
curing of such failure or breach within a reasonable time; or

     (d) Tenant or any Guarantor  (i) files,  or consents by answer or otherwise
to the  filing  against  it of, a  petition  for  relief  or  reorganization  or
arrangement  or any other  petition in bankruptcy or for  liquidation or to take
advantage of any  bankruptcy,  insolvency  or other  debtors'  relief law of any
jurisdiction,  (ii) makes an assignment for the benefit of its creditors,  (iii)
consents to the appointment of a custodian,  receiver,  trustee or other officer
with similar powers of Tenant (or any Guarantors) or of any substantial  part of
Tenant's (or any Guarantor's)  property, or (iv) takes action for the purpose of
any of the foregoing; or

     (e) Without  consent by Tenant or a Guarantor (as the case may be), a court
or government  authority  enters an order,  and such order is not vacated within
thirty (30) days, (i) appointing a custodian, receiver, trustee or other officer
with similar powers with respect to Tenant or any Guarantor,  or with respect to
any  substantial  part  of  Tenant's  or  any  Guarantor's   property,  or  (ii)
constituting  an order  for  relief  or  approving  a  petition  for  relief  or
reorganization  or  arrangement  or any  other  petition  in  bankruptcy  or for
liquidation or to take advantage of any bankruptcy, insolvency or other debtors'
relief law of any jurisdiction, or (iii) ordering the dissolution, winding-up or
liquidation of Tenant or any Guarantor; or

     (f) This Lease or any estate of Tenant  hereunder  is levied upon under any
attachment or execution and such  attachment or execution is not vacated  within
thirty (30) days; or

     (g) Tenant vacates or abandons the Premises; or

     (h) Any Lease  Guaranty  (as defined in section  24.1) ceases to be in full
force and effect; or

     (i) Tenant  merges or sells or transfers  all or  substantially  all of its
assets  (whether  or not the assets sold or  transferred  include  this  Lease),
unless Landlord consents to such transaction in accordance with section 12.1.

     14.2 If an Event of Default  occurs,  Landlord  shall have the right at any
time to give a written  termination  notice to Tenant and, on the date specified
in such notice,  Tenant's  right to  possession  shall  terminate and this Lease
shall terminate. Upon such termination, Landlord shall have the right to recover
from Tenant:

     (a) The worth at the time of award of all unpaid rent which had been earned
at the time of termination;

     (b) The worth at the time of award of the amount by which all  unpaid  rent
which would have been earned after  termination  until the time of award exceeds
the amount of such  rental loss that Tenant  proves  could have been  reasonably
avoided;
<PAGE>
                                       24


     (c) The worth at the time of award of the amount by which all  unpaid  rent
for the  balance of the term of this Lease  after the time of award  exceeds the
amount of such rental  loss that  Tenant  proves  could be  reasonably  avoided;
provided that, in the event that, at the time of the  termination of this Lease,
the Premises or any substantial  portion of the Premises have not been relet, in
lieu of such  amount,  Landlord  shall be entitled to withdraw  the balance then
held in the Draw Account and retain such balance as  liquidated  damages for the
loss of the rents  payable  under this Lease for the balance of the term of this
Lease, in which event such  liquidated  damages would be accepted by Landlord in
full satisfaction of all damages suffered by Landlord for the loss of rents that
would have been  payable  under the Lease with  respect to the period  after the
date of termination  of the Lease.  The amount of funds from time to time in the
Draw Account  pursuant to this Article 24 (subject to section  12.4) is referred
to herein as the "Stipulated Difference." Tenant and Landlord agree that (a) the
Stipulated  Difference is a fair and  reasonable  estimate of the  difference in
value of the Premises if Tenant's covenants and obligations, as tenant under the
Leases,  are performed in all material respects and the value of the Premises if
such covenants and obligations are not performed in all material  respects,  (b)
that the  definition  of the term  "Event  of  Default"  reflects  Tenant's  and
Landlord's  negotiated  agreement as to a fair standard for determining  whether
such covenants and obligations are being performed in all material respects, and
(c) that such difference in value will not be precisely calculable since it will
involve  complex  and  intangible  factors  such as  reduced  salability  of the
Premises,  reduced  creditworthiness of Landlord and harm to Landlord's business
reputation. Said liquidated damages would not be in lieu of or otherwise replace
amounts that Landlord would be entitled to collect under sections  14.2(a),  (b)
and (d), and  Landlord  would be entitled to collect all of the same from Tenant
in addition to the liquidated damages provided for in this section 14.2(c); and

     (d)  All  other  amounts  necessary  to  compensate  Landlord  for  all the
detriment  proximately  caused by  Tenant's  failure to perform  all of Tenant's
obligations  under this Lease or which in the ordinary course of things would be
likely  to result  therefrom.  The  "worth at the time of award" of the  amounts
referred to in clauses (a) and (b) above shall be computed by allowing  interest
at the  Interest  Rate (as  defined in section  3.4).  The "worth at the time of
award" of the  amount  referred  to in clause  (c) above  shall be  computed  by
discounting such amount at the discount rate of the Federal Reserve Bank located
nearest the Premises at the time of award plus one percent (1%). For the purpose
of  determining  unpaid  rent under  clauses  (a),  (b) and (c) above,  the rent
reserved  in this Lease  shall be deemed to be the total rent  payable by Tenant
under Articles 3 and 5 hereof.

     14.3 If an Event of Default occurs,  Landlord may, without terminating this
Lease, terminate Tenant's right to possession of the Premises, in which event:

          (a) Landlord may, with or without process of law, retake possession of
     the Premises;
<PAGE>
                                       25


          (b) Tenant's obligations under this Lease (including the obligation to
     pay rent on the dates  specified in this Lease) shall  continue  unaffected
     for the entire  term of this Lease or until such  earlier  time as Landlord
     may, at its option,  elect to terminate  this Lease which  Landlord may, at
     its option, do at any time;

          (c) Without  being  deemed to have  elected to  terminate  this Lease,
     Landlord  may relet the  Premises in  accordance  with section 14.4 for the
     account of Tenant, in the name of Landlord or in the name of Tenant on such
     terms  and  conditions  and  to  such  tenants  as  Landlord  may,  in  its
     discretion, determine. Landlord shall be entitled to remodel and repair the
     Premises,  to subdivide the  Premises,  or to combine all or any portion or
     portions of the Premises with other  premises in any manner which  Landlord
     shall deem  appropriate in order to accomplish such  reletting;  and Tenant
     shall  reimburse  Landlord,  on  demand,  for all  costs  and  expenses  in
     connection  with  such  repair  or  remodeling  and  reletting  ("Reletting
     Costs").    Notwithstanding   Landlord's   recovery   of   possession   and
     notwithstanding  any  reletting,  Tenant  shall  continue  to pay all  rent
     provided  for  herein  as and when it  comes  due,  less  the net  proceeds
     received by Landlord from any reletting;  provided that, if the proceeds of
     reletting  exceed the amount due from Tenant,  on or before the 15th day of
     each month,  Landlord  shall  refund to Tenant any amount by which the rent
     paid by  Tenant  through  such  date,  when  added to the  amount,  if any,
     recovered by Landlord  through any  reletting of the Premises  through such
     date,  reduced  by all  Reletting  Costs  for  which  Tenant  has not  paid
     Landlord,  and reduced by all amounts  Landlord has previously  refunded to
     Tenant under this  subsection,  and reduced any other  amounts  Tenant owes
     Landlord  under this Lease,  exceeds the rent due under this Lease  through
     such date.  Tenant shall  reimburse  Landlord upon demand for all Reletting
     Costs  and any  other  costs  and  expenses  which  Landlord  may  incur in
     connection with recovery of possession or repair of the Premises;

          (d) In the event Landlord  proceeds under this section 14.3,  Landlord
     may at any time terminate this Lease by notice to Tenant.  Such termination
     shall  have the effect  specified  in section  14.2 and  Landlord  shall be
     entitled to all remedies under section 14.2 upon termination.

     14.4  Landlord  shall have no duty to attempt to  mitigate  its  damages by
retaking  and  reletting  the  Premises;  provided  that,  if  Landlord  retakes
possession of the Premises under either  section 14.2 or section 14.3,  Landlord
shall use good faith  reasonable  efforts to relet the Premises,  subject to the
following terms, conditions and limitations:
<PAGE>
                                       26


          (a) Any reletting of the Premises shall be on the terms and conditions
     determined by Landlord in its reasonable good faith  discretion and to such
     tenants as Landlord shall approve in its reasonable good faith  discretion.
     Without limiting the generality of the foregoing, Tenant acknowledges that,
     in reletting the Premises, Landlord may legitimately consider the effect of
     any such  reletting  on the  Premises  and on any other  property  owned by
     Landlord or any other person or entity controlling, controlled by, or under
     common control with Landlord,  or otherwise affiliated with Landlord (which
     parties are referred to herein collectively as "Landlord Affiliates"), and,
     therefore,  may decide not to lease the  Premises  at rates which are lower
     than Landlord is otherwise  endeavoring to maintain in the Premises,  or at
     rates  which  are  lower  than  the  rate  that  Landlord  believes  to  be
     appropriate for the Premises.

          (b)  Tenant   recognizes  that  Landlord  and  Landlord's   Affiliates
     currently and in the future may have vacant space in the Premises and other
     property  and may in the future also have vacant  space in new  projects in
     competition  with the Premises.  In no event shall Landlord be obligated to
     use any effort to relet the  Premises  in  preference  to leasing  any such
     other  vacant  space  then  available  for  leasing by  landlord  or any of
     Landlord's  Affiliates.  Landlord  shall not be  deemed  to have  failed to
     mitigate  damages  solely on account of the  leasing of other  space  which
     Landlord or Landlord's  Affiliates have available  instead of the reletting
     of the Premises.

     14.5 Whether or not Landlord  elects to terminate  this Lease on account of
any Event of Default by Tenant,  and  subject to  Landlord's  duty to attempt to
mitigate  its  damages  as  provided  herein,  Landlord  shall have the right to
terminate  any and all  subleases,  licenses,  concessions  or other  consensual
arrangements for possession entered into by Tenant and affecting the Premises or
may,  in  Landlord's  sole  discretion,  succeed to  Tenant's  interest  in such
sublease,  licenses,  concessions  or  arrangements.  In the event of Landlord's
election  to succeed  to  Tenant's  interest  in any such  subleases,  licenses,
concessions or arrangements,  Tenant shall, as of the date of notice by Landlord
of such  election,  have no further  right to or  interest  in the rent or other
consideration  receivable  thereunder,  except that amounts actually received by
Landlord  thereunder  shall be credited  against  any amounts  payable by Tenant
hereunder.

     14.6 Except as otherwise provided in section 14.2(c), the remedies provided
for in this Lease are in addition to all other remedies available to Landlord at
law or in equity by statute or otherwise.

     14.7 All  agreements  and  covenants  to be performed or observed by Tenant
under this Lease  shall be at  Tenant's  sole cost and  expense  and without any
abatement of rent.  If Tenant fails to pay any sum of money to be paid by Tenant
or to perform any other act to be performed by Tenant under this Lease, Landlord
shall  have the  right,  but shall not be  obligated,  and  without  waiving  or
releasing Tenant from any obligations of Tenant,  to make any such payment or to
perform  any such other act on behalf of Tenant in  accordance  with this Lease.
All sums so paid by Landlord and all necessary  incidental costs shall be deemed
additional  rent hereunder and shall be payable by Tenant to Landlord on demand,
together with interest on all such sums from the date of expenditure by Landlord
to the date of repayment by Tenant at the Interest Rate. Landlord shall have, in
addition  to all other  rights and  remedies  of  Landlord,  the same rights and
remedies in the event of the  nonpayment of such sums plus interest by Tenant as
in the case of default by Tenant in the payment of rent.

                                       27


     14.8 If Tenant  abandons or surrenders the Premises,  or is dispossessed by
process of law or otherwise, any movable furniture, equipment, trade fixtures or
personal  property  belonging to Tenant and left in the Premises shall be deemed
to be abandoned, at the option of Landlord, and Landlord shall have the right to
sell  or  otherwise  dispose  of  such  personal  property  in any  commercially
reasonable manner.


                                   ARTICLE 15

                              Damage or Destruction

     15.1 If the  Premises,  or any part  thereof,  is  damaged by fire or other
casualty before the Commencement  Date or during the term of this Lease,  Tenant
shall repair such damage and restore the Premises to  substantially  the same or
better  condition  as  existed  before  the  occurrence  of such  fire or  other
casualty, Tenant shall repair and replace all such movable furniture, equipment,
trade fixtures and personal property,  and this Lease shall remain in full force
and effect.  Such repair and  replacement  by Tenant shall be done in accordance
with  Article 9. In no event shall rent abate.  Provided  that Tenant shall have
unconditionally  ratified  in writing  its repair  and  restoration  obligations
pursuant to this section 15.1 with respect to such  casualty,  Tenant shall have
the right to participate  in the adjustment of any insurance  claim arising from
such casualty and shall have the right to approve any  settlement or adjustment,
which approval shall not unreasonably be withheld or delayed. Provided Tenant is
not in  default  under this Lease  (and no event has  occurred  which,  with the
passage of time, the giving of notice, or both, would constitute a default), and
provided  Tenant has (i) delivered to Landlord  plans and  specifications  and a
budget  for such  repair  and  restoration  (all of which  Landlord  shall  have
approved in its reasonable  judgment),  and (ii) deposited with Landlord cash in
the sum  equal to the  excess,  if any,  of the  total  cost  set  forth in such
approved  budget over the amount of  insurance  proceeds  received on account of
such  casualty,  then  Landlord  shall make  available  to Tenant all  insurance
proceeds  actually  received  by  Landlord  on  account  of such  casualty,  for
application to the costs of such approved repair and restoration, as follows:
<PAGE>
                                       28


          (a) No more  frequently  than  once per  calendar  month,  Tenant  may
     request that  Landlord  reimburse  Tenant for costs  incurred by Tenant for
     work in place to repair and restore  the  Premises  during the  immediately
     preceding calendar month.  Tenant's request shall certify that all work for
     which reimbursement is requested was performed in compliance with the plans
     and  specifications  approved  by  Landlord  pursuant  to Article 9 and all
     applicable laws, and shall include reasonably  satisfactory evidence of the
     costs  incurred  by Tenant  and  unconditional  lien  releases  in form and
     substance   required  by  applicable   law  executed  by  all   mechanic's,
     materialmen,  laborers, suppliers and contractors who performed any portion
     of the repair work or supplied materials.

          (b)  Within  fifteen  (15)  days  after  receiving  Tenant's  request,
     Landlord shall approve or disapprove Tenant's request, which approval shall
     not be  unreasonably  withheld,  by written  notice to Tenant.  If Landlord
     approves all or any portion of a request and Landlord has received (and not
     previously  disbursed)  insurance proceeds,  then Landlord's approval shall
     include a check in the amount approved by Landlord. If Landlord disapproves
     all or any portion of a request,  then  Landlord's  notice  shall state the
     reasons  for that  disapproval.  Landlord's  failure  to  deliver  a notice
     approving or disapproving a request shall be conclusively deemed Landlord's
     disapproval of the request.  In addition,  Landlord shall have the right to
     impose other  conditions  upon  disbursement so long as they are consistent
     with customary  construction  loan disbursement  practices.  Landlord shall
     maintain in an  interest-bearing  account any proceeds of insurance held by
     Landlord and any sums  deposited  with Landlord by Tenant  pursuant to this
     section  15.1,  and so long as no  default  by Tenant  under this Lease has
     occurred, interest earned on such account shall be disbursed to Tenant upon
     completion  of such  repair  and  restoration,  except to the  extent  such
     interest has been applied to the costs of such repair and restoration.

     15.2 If the  Premises,  or any part  thereof,  is  damaged by fire or other
casualty and (a) such fire or other casualty  occurs during the last twelve (12)
months  of the term of this  Lease and the  repair  and  restoration  work to be
performed  by Tenant in  accordance  with section  15.1  cannot,  as  reasonably
estimated by Landlord,  be completed within four (4) months after the occurrence
of such  fire or other  casualty,  or (b) the  insurance  proceeds  received  by
Landlord and Tenant in respect of such damage are not adequate to pay the entire
cost, as reasonably estimated by Landlord, of the repair and restoration work to
be  performed  by Landlord in  accordance  with section 15.1 and Tenant does not
deposit such shortfall with  Landlord,  then, in any such event,  Landlord shall
have the right,  by giving written notice to Tenant within sixty (60) days after
the occurrence of such fire or other casualty, to terminate this Lease as of the
date of such  notice,  in which case all  insurance  proceeds on account of such
casualty  shall be paid to Landlord.  If Landlord does not exercise the right to
terminate this Lease in accordance  with this section 15.2,  Tenant shall repair
such damage and restore the  Premises in  accordance  with section 15.1 and this
Lease shall remain in full force and effect.

                                   ARTICLE 16

                                 Eminent Domain

     16.1 If a  substantial  portion of the Premises is taken and the  remaining
portion of the Premises is not reasonably suitable for Tenant's purposes,  or if
a portion of the Premises is taken resulting in a substantial  loss of access to
and from the Premises  without  reasonable  substitute  access being  available,
Landlord and Tenant each shall have the right,  by giving  written notice to the
other within thirty (30) days after the date of such taking,  to terminate  this
Lease. If either Landlord or Tenant exercises such right to terminate this Lease
in accordance  with this section 16.1, this Lease shall terminate as of the date
of such taking. If neither Landlord nor Tenant exercises such right to terminate
this Lease in accordance  with this section 16.1,  this Lease shall terminate as
to the portion of the  Premises so taken as of the date of such taking and shall
remain in full force and effect as to the portion of the  Premises not so taken,
Tenant shall  restore the portion of the Premises not so taken to an  integrated
architectural  unit in  accordance  with  Article 9 and the Base  Rent  shall be
reduced as of the date of such taking in the  proportion  that the rentable area
of the Premises so taken bears to the total  rentable area of the  Premises.  If
all of the Premises is taken by exercise of the power of eminent  domain  before
the  Commencement  Date or  during  the term of this  Lease,  this  Lease  shall
terminate as of the date of such taking.

     16.2 If all or any part of the  Premises  is taken by exercise of the power
of eminent domain, all awards, compensation,  damages, income, rent and interest
payable in connection  with such taking shall,  except as expressly set forth in
this section  16.2,  be paid to and become the property of Landlord,  and Tenant
hereby assigns to Landlord all of the foregoing. Without limiting the generality
of the  foregoing,  Tenant  shall have no claim  against  Landlord or the entity
exercising  the power of eminent  domain for the value of the  leasehold  estate
created by this Lease or any unexpired term of this Lease. Tenant shall have the
right to claim and  receive  directly  from the entity  exercising  the power of
eminent domain only the share of any award  determined to be owing to Tenant for
the taking of improvements  installed in the portion of the Premises so taken by
Tenant at Tenant's sole cost and expense based on the unamortized  cost actually
paid by  Tenant  for such  improvements,  for the  taking  of  Tenant's  movable
furniture,  equipment,  trade  fixtures  and  personal  property,  for  loss  of
goodwill,  for interference  with or interruption of Tenant's  business,  or for
removal and relocation expenses.
<PAGE>
                                       30


     16.3 In the event of any taking other than a taking  referred to in section
16.1, this Lease shall continue in full force and effect,  Tenant shall continue
to pay  all of the  rent  and to  perform  all of the  covenants  of  Tenant  in
accordance  with  this  Lease  and  Tenant  shall  restore  the  Premises  to an
integrated  architectural  unit in accordance with Article 9. Provided Tenant is
not in  default  under this Lease  (and no event has  occurred  which,  with the
passage of time, the giving of notice, or both, would constitute a default), and
provided  Tenant has (i) delivered to Landlord  plans and  specifications  and a
budget  for such  repair  and  restoration  (all of which  Landlord  shall  have
approved in its reasonable  judgment),  and (ii) deposited with Landlord cash in
the sum  equal to the  excess,  if any,  of the  total  cost  set  forth in such
approved  budget  over the amount of  condemnation  award  proceeds  received on
account  of such  taking,  then  Landlord  shall  make  available  to Tenant all
condemnation  award  proceeds  actually  received by Landlord on account of such
taking, for application to the costs of such approved repair and restoration, as
follows:

          (a) No more  frequently  than  once per  calendar  month,  Tenant  may
     request that  Landlord  reimburse  Tenant for costs  incurred by Tenant for
     work in place to repair and restore  the  Premises  during the  immediately
     preceding calendar month.  Tenant's request shall certify that all work for
     which reimbursement is requested was performed in compliance with the plans
     and  specifications  approved  by  Landlord  pursuant  to Article 9 and all
     applicable laws, and shall include reasonably  satisfactory evidence of the
     costs  incurred  by Tenant  and  unconditional  lien  releases  in form and
     substance   required  by  applicable   law  executed  by  all   mechanic's,
     materialmen,  laborers, suppliers and contractors who performed any portion
     of the repair work or supplied materials.

          (b)  Within  fifteen  (15)  days  after  receiving  Tenant's  request,
     Landlord shall approve or disapprove Tenant's request, which approval shall
     not be  unreasonably  withheld,  by written  notice to Tenant.  If Landlord
     approves all or any portion of a request and Landlord has received (and not
     previously disbursed) condemnation award proceeds, then Landlord's approval
     shall  include a check in the amount  approved  by  Landlord.  If  Landlord
     disapproves all or any portion of a request,  then Landlord's  notice shall
     state the reasons  for that  disapproval.  Landlord's  failure to deliver a
     notice  approving or  disapproving a request shall be  conclusively  deemed
     Landlord's disapproval of the request. In addition, Landlord shall have the
     right to impose  other  conditions  upon  disbursement  so long as they are
     consistent  with  customary   construction  loan  disbursement   practices.
     Landlord shall  maintain in an  interest-bearing  account any  condemnation
     award held by  Landlord  and any sums  deposited  with  Landlord  by Tenant
     pursuant to this  section  16.3,  and so long as no default by Tenant under
     this Lease has occurred, interest earned on such account shall be disbursed
     to Tenant upon  completion  of such repair and  restoration,  except to the
     extent  such  interest  has been  applied  to the costs of such  repair and
     restoration.

     16.4 As used in this Article 16, a "taking" means the acquisition of all or
part of the Premises for a public use by exercise of the power of eminent domain
(or a sale of any or all of the Premises in lieu, or under threat,  thereof) and
the taking shall be  considered  to occur as of the earlier of the date on which
possession of the Premises (or part so taken) by the entity exercising the power
of eminent domain is authorized as stated in an order for possession or the date
on which title to the Premises (or part so taken) vests in the entity exercising
the power of eminent domain.


                                   ARTICLE 17

                         Subordination, Merger and Sale

     17.1 This Lease shall be subject and  subordinate  at all times to the lien
of all mortgages and deeds of trust  securing any amount or amounts  whatsoever,
and any ground  lease or master  lease of the  Premises,  which may now exist or
hereafter  be placed on or against  the  Premises  or on or  against  Landlord's
interest  or estate  therein,  all  without  the  necessity  of  having  further
instruments executed by Tenant to effect such subordination. Notwithstanding the
foregoing,  in the event of a foreclosure  of any such mortgage or deed of trust
or of any other action or proceeding for the enforcement thereof, or of any sale
thereunder, or in the event any such ground lease or master lease is terminated,
this Lease shall not be  terminated  or  extinguished,  nor shall the rights and
possession of Tenant hereunder be disturbed,  if no Event of Default then exists
under this Lease, and Tenant shall attorn to the person who acquires  Landlord's
interest hereunder through any such mortgage or deed of trust.  Tenant agrees to
execute, acknowledge and deliver upon demand such further instruments evidencing
such  subordination of this Lease to the lien of all such mortgages and deeds of
trust or to all such  ground  leases or master  leases  of the  Premises  as may
reasonably be required by Landlord,  but Tenant's  covenant to subordinate  this
Lease to  mortgages  or deeds of  trust,  or ground  leases  or  master  leases,
hereafter  executed is  conditioned  upon each such  senior  mortgage or deed of
trust, or ground lease or master lease, or a separate  subordination  agreement,
containing the commitments specified in the preceding sentence. Without limiting
the  generality of the foregoing,  Tenant agrees to enter into a  subordination,
nondisturbance  and  attornment  agreement in the form required by the holder of
any such  mortgage or deed of trust or by any party to any such ground  lease or
master lease.

     17.2 The voluntary or other surrender of this Lease by Tenant,  or a mutual
cancellation  thereof,  shall  not work a merger  and  shall,  at the  option of

     24.2 As a condition  precedent for Landlord's  benefit to the effectiveness
of this Lease and the  Commencement  Date,  on or before the  Commencement  Date
Tenant shall  deposit with  Landlord by wire  transfer the amount of ten million
dollars  ($10,000,000)  (the  "Security  Amount")  to be held by  Landlord  as a
security  deposit in accordance  with this Article 24. The Security Amount shall
be held in an  interest-bearing  account in Landlord's own name as secured party
with  respect  to the  security  interest  hereby  granted  by  Tenant,  as cash
collateral  (the  "Draw  Account"),  established  with a  financial  institution
selected by Landlord and reasonably  satisfactory  to Tenant.  Funds in the Draw
Account  shall  be  invested  in  such  Permitted  Investments  (as  hereinafter
defined),  as  Tenant  may from  time to time  designate  by  written  notice to
Landlord  and as approved by Landlord  in its  reasonable  discretion.  The term
"Permitted  Investments"  means money market  accounts with, or  certificates of
deposit issued by, a national bank or other depository institution which bank or
institution is  satisfactory to Landlord in its sole  discretion;  United States
Treasury  securities;  or  commercial  paper rated AAA or better by Standard and
Poors Corporation (or equivalent rating of another nationally  recognized credit
rating  agency).  Risk of loss of the amounts held in the Draw Account  shall be
borne  by  Tenant,  and  Landlord  shall  have no  liability  for any  loss,  or
diminution  in  value,  of the Draw  Account  due to any  failure  of,  or other
financial problems affecting, such financial institution. Interest earned on the
Draw Account  shall for all purposes  become part of the Draw  Account.  On each
anniversary  of the date the funds are  deposited in the Draw  Account,  amounts
held in the Draw Account in excess of the Security  Amount (as the same may have
been  adjusted  pursuant to section  24.6) shall be  disbursed  as follows:  (a)
first,  to pay all reasonable  costs to establish and maintain the Draw Account;
and (b) second, the balance, if any, to Tenant. Tenant hereby grants to Landlord
a security  interest in the Draw Account and all proceeds  thereof to secure the
full and  timely  performance  of  Tenant's  obligations  under this  Lease.  In
addition to the remedies set forth in this Lease, Landlord shall have all of the
rights and remedies of a secured  party  pursuant to the  Massachusetts  Uniform
Commercial Code. At any time upon Landlord's  request,  Tenant shall execute and
deliver to Landlord such security agreements, financing statements and other

documents as Landlord  may  reasonably  require to further  evidence and perfect
such security interest.

     24.3 If this Lease is  terminated  and  Landlord is entitled to  liquidated
damages in  accordance  with section  14.2(c),  Landlord may withdraw all of the
funds then remaining in the Draw Account and retain the withdrawn amount.

     24.4 Landlord may, from time to time,  withdraw funds from the Draw Account
for application  against any installment of Rent not paid when due or to pay any
other amount payable by Tenant  hereunder  that is not paid when due,  including
amounts  payable by Tenant  under this Lease to  reimburse  Landlord for amounts
paid by Landlord for the account of Tenant as provided for in this Lease.

     24.5 In the event of a partial withdrawal of funds from the Draw Account in
accordance with section 24.4, Tenant shall,  within five (5) business days after
Landlord has given Tenant notice of such  withdrawal  (including  the purpose of
such withdrawal),  deposit to the Draw Account such additional funds as shall be
necessary to cause the amount of funds in the Draw Account to be returned to the
Security Amount and if Tenant fails to do so within that 5-day period,  an Event
of Default shall be deemed to have occurred and the Landlord may terminate  this
Lease and/or exercise any of its other rights and remedies, including its rights
under this Article 24.

     24.6 The Security  Amount shall be subject to  adjustment  on the terms and
conditions  set  forth  in this  section  24.6.  As of  April  15 of  each  year
commencing  with April 15, 2001 (each a "Reduction  Date"),  the Security Amount
shall be reduced by the Reduction  Amount (as defined below)  applicable to such
Reduction  Date,  provided that, as of such Reduction Date, all of the following

Upon the occurrence of any Reduction Event,  Landlord shall deliver to Tenant an

adjusted Security Amount becoming effective upon such Reduction Date.

     24.7(a)  The  Security  Amount  shall be  reduced to five  million  dollars
($5,000,000)   at  any  time  that  Tenant   delivers  to  Landlord   reasonably

equal to the excess (if any) of the funds then held in the Draw Account over the
adjusted Security Amount becoming effective upon such reduction. If the Security
Amount is less than five million  dollars  ($5,000,000),  this  section  24.7(a)
shall have no effect.

     (b) Tenant's  obligations  pursuant to this Article 24 to provide  security
shall terminate,  and Landlord shall return to Tenant all funds remaining in the

     continuous  period of not less  than  eighteen  (18)  months  (without  any

     of BBB- or better from S&P or Baa3 or better from Moody's,  and a rating of
     its  unsecured  debt of BBB- or better from Duff & Phelps Credit Rating Co.
     ("Duff");

provided that, as of the time that Tenant  delivers to Landlord such evidence of
such ratings, no Event of Default has occurred and is continuing.

     24.8 Upon the  expiration  or sooner  termination  of this Lease,  Landlord
shall return to Tenant any funds  remaining in the Draw  Account,  provided that
Landlord  shall  have the  right to  retain  in the Draw  Account  (and  draw in

to be equal to the  damages  Landlord  has  suffered  arising  from any  uncured
default by Tenant.

     24.9 So long as no Event of Default has occurred and is continuing,  Tenant
shall have the right to provide Landlord,  in lieu of the security  described in
this Article 24, an  irrevocable  standby  letter of credit in the amount of the
Security Amount, in form and substance  satisfactory to Landlord and issued by a
bank satisfactory to Landlord (a "Letter of Credit"). In the event Tenant elects
to so provide a Letter of Credit,  Landlord and Tenant  shall  negotiate in good
faith an  amendment  to this Lease to set forth the rights  and  obligations  of
Landlord  and Tenant  with  respect to the Letter of Credit,  the terms of which
amendment  shall  provide  Landlord  with  comparable  security,  in  Landlord's
reasonable judgment, to that provided pursuant to this Article 24.

                                   ARTICLE 26

                          Option to Expand the Building

     26.1(a)  Upon and subject to the terms and  conditions  of this Article 26,
Landlord hereby grants to Tenant the right and option (the  "Expansion  Option")
(i) to request that Landlord  construct the Expansion  Improvements  (as defined
below)  and lease the  Expansion  Improvements  to  Tenant  in  accordance  with
sections  26.2 and 26.4,  or (ii) to request that Landlord  purchase  from,  and
lease back to, Tenant the  Expansion  Improvements  upon  Tenant's  construction
thereof in accordance with sections 26.3 and 26.4, or (iii) if Landlord declines
to  construct  or  purchase  from  Tenant  the  Expansion  Improvements,  to (A)
subdivide  the  Premises  and  purchase the portion of the Premises on which the
Expansion  Improvements  are  to be  constructed  and  construct  the  Expansion
Improvements  itself in  accordance  with section  26.5,  or (B)  construct  the
Expansion  Premises itself as a leasehold  improvement  without  subdividing the
Premises in accordance with section 26.6.

     (b) The additional  improvements to be constructed if the Expansion  Option
is exercised (the "Expansion  Improvements")  shall (i) be one or more buildings
separate from the existing  Building,  of design,  nature and type substantially
similar  to the  existing  Building,  and (ii) be of a size and be  located  and
configured  per the  location and  configuration  of "Phase 2" shown in the Site
Plan  attached  hereto as  Exhibit  C,  unless  at the  request  of the  Tenant,
Landlord, in its sole and absolute discretion, shall agree to construct or allow
Tenant to construct  Expansion  Improvements  of a different  design,  nature or
type.  Landlord  shall  have the  right,  but not the  obligation,  to provide a
proposal to construct the Expansion Improvements.
<PAGE>
                                       44


     (c) The  Expansion  Option  shall be  exercised  by Tenant,  if at all,  by
written  notice  thereof (an  "Expansion  Notice") to Landlord given not earlier
than the  Commencement  Date and not later than the tenth (10th)  anniversary of
the Commencement Date (the "Exercise Period").  The Expansion Notice may propose
either one or two buildings and shall be accompanied  by preliminary  conceptual
plans and specifications for the Expansion  Improvements  ("Preliminary Plans").
The Expansion  Notice shall specify whether Tenant (i) proposes to construct the
Expansion Improvements itself and requests that Landlord purchase and lease back
the Expansion  Improvements  in accordance  with sections 26.3 and 26.4, or (ii)
requests that Landlord  construct the Expansion  Improvements  and lease them to
Tenant in accordance  with sections 26.2 and 26.4.  The Expansion  Option may be
exercised  from time to time,  each  exercise  relating  to a single  additional
building.  No purported  exercise of the Expansion Option which fails to satisfy
the  conditions  set forth in section 26.7 and no valid  exercise which is later
rescinded  shall impair  Tenant's  right  thereafter  to exercise the  Expansion
Option during the Exercise  Period.  As of the end of the Exercise  Period,  the
Expansion  Option shall lapse and be of no further  force and effect,  except to
the extent theretofore exercised. Time is of the essence of this provision.

     26.2  If  the  Expansion  Notice  requests  that  Landlord  constructs  the
Expansion  Improvements,  then not later than sixty (60) days after  delivery of
the Expansion Notice, Landlord shall notify Tenant if it elects not to construct
the  Expansion   Improvements  (which  election  shall  be  in  Landlord's  sole
discretion),  or, in the event  Landlord  proposes to  construct  the  Expansion
Improvements,  Landlord  shall  submit  to Tenant a notice  (the  "Specification
Notice") which notice shall contain  Landlord's  best good faith estimate of (a)
the total costs (hard and soft) of constructing the Expansion Improvements,  (b)
the  projected  date for  completion  and  delivery  to Tenant of the  Expansion
Improvements,  and (c) the projected  Expansion Base Rent.  Tenant may elect, by
written notice to Landlord within sixty (60) days following  Tenant's receipt of
the Specification Notice, either to accept the terms of the Specification Notice
or to rescind its exercise of the Expansion  Option. In the event Landlord shall
have  notified  Tenant  that  Landlord  elects not to  construct  the  Expansion
Improvements,  then Tenant may elect, by written notice to Landlord within sixty
(60) days following Tenant's receipt of Landlord's notice, to either (i) rescind
its exercise of the Expansion  Option,  (ii) exercise the right (the  "Leasehold
Improvement Option") to construct the Expansion  Improvements on the Premises at
its sole cost in accordance  with section 26.6, or (iii) exercise the right (the
"Tenant  Subdivision  Option") to cause the Premises to be subdivided  such that
the site on which the proposed Expansion Improvements are to be constructed (the
"Expansion  Site") is a separate legal parcel in compliance  with all applicable
laws,  codes,  ordinances and regulations  and with the  requirements of section
26.5 and to  purchase  the  Expansion  Site  from  Landlord  and  construct  the
Expansion  Improvements  itself, all in accordance with section 26.5;  provided,
however,  that if Tenant elects to either  rescind the exercise of the Expansion
Option or to exercise the Tenant Subdivision Option or the Leasehold Improvement
Option,  Tenant shall pay to Landlord as additional rent an amount equal to 150%
of Landlord's out-of-pocket costs incurred to third parties (including,  without
limitation,  architects,  engineers and other design professionals) in preparing
the Specification  Notice, and Tenant shall, upon payment, be entitled to copies
of all plans,  specifications  and designs.  Tenant's failure to timely exercise
the Tenant  Subdivision  Option or the  Leasehold  Improvement  Option  shall be
conclusively  deemed to constitute a rescission of the exercise of the Expansion
Option. Time is of the essence of this provision.

                                       45


     26.3 If the Expansion Notice proposes that Tenant  constructs the Expansion
Improvements  and requests  that Landlord  purchase the Expansion  Improvements,
then not later  than sixty (60) days after  delivery  of the  Expansion  Notice,
Landlord  shall notify Tenant whether or not it elects to purchase the Expansion
Improvements  (which election shall be in Landlord's sole  discretion),  and the
provisions of subsection (a) or (b) of this section 26.3, as  applicable,  shall
apply.

     (a) In the event Landlord shall have notified  Tenant that Landlord  elects
to purchase the Expansion  Improvements  (the  "Purchase  Notice"),  then Tenant
shall undertake construction of the Expansion Improvements ("Tenant's Work") and
the provisions of section  26.3(a)(i) through  26.3(a)(ix)  hereinbelow shall be
applicable.

          (i) Tenant shall cause to be constructed the Expansion Improvements in
     accordance   with  all  applicable   laws  and  the  procedures  set  forth
     hereinbelow.  Upon the  Expansion  Rent  Commencement  Date (as  defined in
     section  26.4(a)),  Landlord  shall  purchase  and  Tenant  shall  sell the
     Expansion  Improvements  for a net price equal to Tenant's  Expansion Costs
     (as defined  below),  and Tenant shall execute and deliver to Landlord such
     documents and instruments as Landlord may reasonably  request in connection
     with such purchase and sale. The term "Tenant's  Expansion Costs" means all
     hard and soft  costs  incurred  by Tenant  (but  excluding  land  costs) in
     connection with the design and construction of the Expansion  Improvements,
     as said term may be further defined in the Lease Amendment described below.
     Tenant shall pay all closing  costs in  connection  with such  purchase and
     sale,  including the premium for an endorsement to Landlord's  title policy
     to increase  the  liability  amount to reflect  the price of the  Expansion
     Improvements.  From and after the Expansion Rent  Commencement Date and for
     the remainder of the term (as the same may be extended  pursuant to section
     26.4(c)),  Tenant pay Expansion  Base Rent (as defined in section  26.4(a))
     for the Expansion Improvements;  the Expansion Improvements shall be deemed
     to be a part of the Premises hereunder;  and Tenant shall pay all Operating
     Expenses for the Expansion  Improvements as set forth in section 3.1(b) and
     shall  perform all other  obligations  of Tenant under this Lease as if the
     Expansion   Improvements  were  part  of  the  original  Premises.  At  the
     conclusion of this Lease, the Expansion  Improvements shall be delivered to
     Landlord in good condition  (reasonable  wear and tear excepted).  Title to
     the  Expansion  Improvements  shall,  at all  times,  remain in the name of
     Landlord and shall not pass to Tenant.

                                       46


          (ii) On or before ten (10) days from the date of the Purchase  Notice,
     Tenant  shall notify  Landlord of the  identity and mailing  address of the
     licensed  architect  engaged  by Tenant  for the  preparation  of plans for
     Tenant's  Work.  On or  before  forty-five  (45)  days from the date of the
     Purchase  Notice,   Tenant,  at  Tenant's  expense,  shall  cause  Tenant's
     architect  to prepare  and deliver to Landlord  for  Landlord's  reasonable
     approval five (5) sets of final plans and specifications for Tenant's Work.

          (iii) Landlord shall review said plans and  specifications  and notify
     Tenant within fifteen (15) days of receipt of said plans and specifications
     in Landlord's  office, of the matters,  if any, in said plans which fail to
     conform to Landlord's  construction  requirements or otherwise fail to meet
     with Landlord's approval which approval shall not be unreasonably withheld,
     conditioned or delayed.  Tenant shall, within ten (10) days from receipt of
     any such  notice  from  Landlord,  cause  said  plans to be revised in such
     manner as is requisite to  obtaining  Landlord's  approval and shall submit
     revised plans for Landlord's approval.  When Landlord has approved Tenant's
     plans,  Landlord  shall initial and return one (1) set of approved plans to
     Tenant, which set shall also show the date of Landlord's approval. Tenant's
     Work  shall be  carried  out  pursuant  to a fixed  price or  not-to-exceed
     construction  contract in form and  substance  reasonably  satisfactory  to
     Landlord,  and  with  a  licensed  contractor  reasonably  satisfactory  to
     Landlord.  Landlord  shall have the right to  require  that  Tenant  obtain
     payment and  completion  bonds on terms  satisfactory  to Landlord prior to
     commencing Tenant's Work. Tenant agrees not to commence Tenant's Work until
     Landlord has approved the final plans,  the contractor and the construction
     contract,  all  required  permits  have been issued and this Lease has been
     amended in accordance with section 26.8.  Tenant shall  reimburse  Landlord
     for actual costs expended for review of all plans.

          (iv)  Tenant  shall  not  deviate  from the  final  set of  plans  and
     specifications  approved  by  Landlord  without  Landlord's  prior  written
     consent,  which  consent  shall not be  unreasonably  withheld.  Landlord's
     approval of plans and specifications shall not constitute the assumption of
     any  responsibility by Landlord for any of Tenant's Work or the accuracy or
     sufficiency of Tenant's plans and specifications.

          (v) If Tenant fails to complete the Tenant's Work in  accordance  with
     such  plans  and  specifications  prior to the  Construction  Deadline  (as
     defined below),  Landlord,  at Landlord's  option, may terminate this Lease
     or, at Landlord's  option, may enter the Expansion  Improvements,  complete
     Tenant's  Work,  and Tenant  shall pay the cost  thereof to  Landlord  upon
     demand.  The term  "Construction  Deadline"  means the date  eighteen  (18)
     months after  commencement  of  construction,  plus the number of days that
     construction is delayed due to Force Majeure; provided that such date shall
     be extended an additional six (6) months so long as Tenant is  continuously
     and diligently proceeding with construction.

                                       47


          (vi) Tenant shall  comply with and shall  require its  contractors  to
     comply with all federal, state, and local laws, ordinances, regulations and
     directions  relating to the employment,  conditions of employment and hours
     of labor in connection with any construction,  alteration,  installation or
     repair work done by or for Tenant in or about the Premises.  If Landlord is
     damaged  as a result of any  breach by  Tenant of these  covenants,  Tenant
     shall pay to Landlord the amount of such damage, upon demand.

          (vii) Upon completion of  construction of the Expansion  Improvements,
     Tenant shall submit:

               (A)  Properly  notarized  final  releases of liens from  Tenant's
          general contractor and all subcontractors.

               (B)  Properly  notarized  final  releases of liens from  Tenant's
          major suppliers, architect or anyone supplying a significant amount of
          materials  or  services  for  the   construction   of  the   Expansion
          Improvements.

               (C) A certificate of occupancy and a final inspection  report (as
          applicable) from the appropriate  governing body,  indicating that the
          Expansion Improvements has no violation of local building codes.

          (viii) At all times prior to the completion of Tenant's  Work,  Tenant
     shall cause its general  contractor  and  subcontractors  to maintain  such
     insurance as Landlord  may  reasonably  require,  with  insurance  carriers
     reasonably  approved  by  Landlord,   in  amounts  reasonably  approved  by
     Landlord.

          (ix)  Tenant's  Work  shall  be  completed,  lien-free  in a good  and
     workmanlike  manner,  and shall constitute Class A office space constructed
     to the same  standards as the existing  Building.  Tenant  hereby agrees to
     indemnify,  defend and hold Landlord harmless from any and all liens and/or
     claims placed against the Premises,  arising out of, or in connection with,
     Tenant's Work; and  notwithstanding  anything to the contrary  contained in
     this Lease, no liens of any nature,  whether voluntary or involuntary,  may
     be placed or allowed by Tenant on the  Premises.  However,  Tenant may bond
     around any mechanic's  liens within thirty (30) days of recording,  without
     an Event of Default  occurring.  Landlord  shall have no  liability  of any
     kind,  and Tenant  shall be solely  responsible,  for any  defects or legal
     violations respecting the Expansion  Improvements.  Tenant hereby agrees to
     indemnify,  defend and hold  Landlord  harmless from any and all claims and
     liabilities  of any kind,  howsoever  arising,  relating  to the  Expansion
     Improvements and Tenant shall execute an indemnity, reasonably satisfactory
     to Landlord in form and content, prior to commencement of Tenant's Work.
<PAGE>
                                       48


     (b) In the event Landlord shall have notified  Tenant that Landlord  elects
not to purchase the Expansion  Improvements,  then Tenant may elect,  by written
notice  to  Landlord  within  sixty  (60) days  following  Tenant's  receipt  of
Landlord's  notice,  to either (i) rescind its exercise of the Expansion Option,
(ii) exercise the Leasehold  Improvement  Option,  or (iii)  exercise the Tenant
Subdivision  Option.  Tenant's failure to timely exercise the Tenant Subdivision
Option or the  Leasehold  Improvement  Option  shall be  conclusively  deemed to
constitute a rescission of the exercise of the Expansion Option.  Time is of the
essence of this provision.

     26.4(a)  Base  Rent  for  the  Expansion   Improvements  if  the  Expansion
Improvements are constructed by Landlord or if Landlord  purchases the Expansion
Improvements  in  accordance  with  section  26.3(a)  ("Expansion  Base  Rent"),
calculated  as provided in section  26.4(b),  shall  commence upon the date (the
"Expansion Rent Commencement Date") the Expansion Improvements are substantially
completed, subject only to "punch list" items and other items of incomplete work
that do not  materially  interfere  with the use and  occupancy of the Expansion
Improvements (as certified to Landlord and Tenant by the supervising  architect,
or, as evidenced by the  issuance of a temporary  or  permanent  certificate  of
occupancy), and delivered to Tenant for Tenant's occupancy.  Expansion Base Rent
shall be  included  in "Base  Rent" for  purposes  of this  Lease,  and shall be
payable  concurrently  with  payments  of Base  Rent  hereunder  as set forth in
Article 3 of this Lease.  From and after the Expansion Rent  Commencement  Date,
the  Expansion  Improvements  shall  be  deemed  to be a part  of  the  Premises
hereunder,  and in  addition  to  Expansion  Base  Rent,  Tenant  shall  pay all
Operating Expenses for the Expansion Improvements as set forth in section 3.1(b)
and shall  perform all other  obligations  of Tenant  under this Lease as if the
Expansion Improvements were part of the original Premises.

     (b) If  the  Expansion  Improvements  are  constructed  by  Landlord  or if
Landlord  purchases  the  Expansion  Improvements  in  accordance  with  section
26.3(a),  Expansion  Base Rent shall be: (i) for the first  twelve  (12)  months
after the Expansion  Rent  Commencement  Date,  an amount  calculated to provide
Landlord with an annual return on Landlord's investment of Total Expansion Costs
(as defined below) equal to the Rent Yield (as defined below), and (ii) for each
successive twelve (12) month period  thereafter,  an amount equal to one hundred
three percent  (103%) of the Expansion  Base Rent in effect during the preceding
12-month period.  The term "Total Expansion Costs" means all hard and soft costs
incurred by Landlord (including a reasonable development fee payable to Landlord

<PAGE>
                                       49


and financing  charges,  but excluding land costs) in connection with the design
and  construction  of the  Expansion  Improvements,  as said term may be further
defined in the Lease Amendment  described below. In the event Landlord purchases
the Expansion Improvements in accordance with section 26.3(a),  "Total Expansion
Costs"  shall mean  Tenant's  Expansion  Costs.  The term "Rent  Yield"  means a
percentage  equal to Landlord's  Spread (as defined below) plus the Assumed Loan
Constant (as defined below).  The term  "Landlord's  Spread" means (x) if, as of
the  Expansion  Rent  Commencement  Date,  Tenant shall have  satisfied the debt
rating conditions set forth in section 24.7, seventy-five (75) basis points; and
(y) if,  as of the  Expansion  Rent  Commencement  Date,  Tenant  shall not have
satisfied  the debt rating  conditions  set forth in section  24.7,  one hundred
twenty-five  (125)  basis  points.  The term  "Assumed  Loan  Constant"  means a
percentage equal to the percentage of Total Expansion Costs which Landlord would
be required to pay  annually  as debt  service on a secured  loan in a principal
amount equal to Total  Expansion  Costs,  with  amortization of principal over a
term which ends five (5) years  after the term of this Lease (as the same may be
extended  pursuant to section  26.4(c)) and interest at the then prevailing rate
(determined  with reference to loan terms being proposed by major life insurance
company  lenders  such as  Principal  Mutual,  Metropolitan  Life  and  Teachers
Insurance) for fully amortizing mortgage loans of like tenor secured by property
comparable to the Premises. Effective upon the Expansion Rent Commencement Date,
the Security  Amount  shall be  increased  by an amount equal to twenty  percent
(20%) of the Total Expansion Costs,  provided that the Security Amount shall not
be required  to exceed ten million  dollars  ($10,000,000).  Effective  upon the
Expansion Rent Commencement  Date, section 24.6 shall be amended to provide that
the first Reduction Date shall occur on the fourth (4th) April 15 to occur after
the Expansion Rent Commencement Date, and subsequent Reduction Dates shall occur
annually  thereafter  (but the Reduction  Amounts  applicable on the  successive
Reduction Dates shall remain as set forth in section 24.6).

     (c) In the event the  Expansion  Commencement  Date  occurs  later than the
third (3rd)  anniversary of the Commencement  Date, the term of this Lease shall
automatically be extended such that the Expiration Date shall be the date twelve
(12) years after the  Expansion  Commencement  Date.  If Landlord  constructs or
purchases the Expansion  Improvements,  Base Rent for the extended term shall be
calculated  in accordance  with section 3.1 based upon the Base Rent  (including
Expansion Base Rent).

     26.5 In the event that Landlord elects not to undertake construction of the
Expansion  Improvements  or elects not to purchase  the  Expansion  Improvements
pursuant to section 26.3(a),  and Tenant exercises the Tenant Subdivision Option
and elects to undertake  construction of the Expansion  Improvements  ("Tenant's
Work"),  the provisions of section 26.5(a) through 26.5(f)  hereinbelow shall be
applicable.
<PAGE>
                                       50


     (a) Tenant shall,  at its sole cost and expense and upon and subject to the
terms of this section 26.5 and the other  applicable  provisions of this Article
26, (i) cause the  Premises to be  subdivided  so that the  Expansion  Site is a
separate legal parcel, (ii) purchase the Expansion Site from Landlord, and (iii)
cause to be  constructed  the  Expansion  Improvements  in  accordance  with all
applicable laws and the procedures set forth  hereinbelow.  For the remainder of
the term of this Lease, the Expansion Site and the Expansion  Improvements shall
not be a part of the Premises hereunder.

     (b) On or before  forty-five (45) days after the date of Tenant's  exercise
of the Tenant Subdivision Option, Tenant, at Tenant's expense, shall (i) cause a
registered  surveyor  or civil  engineer  to prepare  and  deliver to Landlord a
proposed  subdivision  map (the "Proposed  Subdivision  Map"),  complying in all
respects with all laws, statutes, codes and ordinances,  to legally separate the
Expansion Site and the remainder of the Premises (the  "Remaining  Parcel") such
that each parcel complies with all applicable laws, statutes,  codes, ordinances
and covenants,  conditions and restrictions  ("Legal  Requirements"),  and (iii)
cause  Tenant's  architect  to prepare and deliver to  Landlord  for  Landlord's
approval  five (5) sets of final  plans and  specifications  for  Tenant's  Work
including a detailed depiction of all proposed improvements (the "Final Plans").
The Proposed  Subdivision  Map shall be subject to  Landlord's  approval,  which
shall not be unreasonably withheld. Without limiting the foregoing, Landlord may
disapprove  the Proposed  Subdivision  Map if (A) Landlord  would be required to
expend any sums to improve the Remaining  Parcel to cause it to be in compliance
with any Legal  Requirements,  (B) the  Remaining  Parcel  would,  in Landlord's
reasonable  judgment,  be of less value than the value prior to the  subdivision
minus  the  Site  Price  (as  defined  below),  or (C) the  expense  of  owning,
operating,  managing or maintaining  the Remaining  Parcel would be increased by
the subdivision.  Landlord shall review the Proposed  Subdivision Map and notify
Tenant within fifteen (15) days of receipt of the matters, if any, which fail to
conform to Landlord's reasonable requirements.

     (c) Landlord  shall review the Final Plans and notify Tenant within fifteen
(15) days of receipt of said plans and  specifications in Landlord's  office, of
the matters,  if any, in said plans which fail to meet with Landlord's  approval
which  approval  shall not be  unreasonably  withheld,  conditioned  or delayed.
Tenant  shall,  within  ten (10)  days  from  receipt  of any such  notice  from
Landlord, cause the Proposed Subdivision Map and/or the Final Plans, as the case
may be, to be revised in such manner as is  requisite  to  obtaining  Landlord's
approval and shall submit a revised Proposed  Subdivision Map and/or Final Plans
for Landlord's approval. The Proposed Subdivision Map as approved by Landlord is
referred  to  herein  as  the  "Subdivision  Map."  As  promptly  as  reasonably
practicable  after  Landlord's  approval  of the  Subdivision  Map and the Final
Plans,  Tenant shall cause the Subdivision Map to be recorded and shall take all
other steps necessary to cause the Premises to be subdivided.  Tenant agrees not
to commence  Tenant's Work until Landlord has approved the  Subdivision  Map and
the Final Plans, the Premises has been legally subdivided in accordance with the
approved  Subdivision Map, Tenant has purchased the Expansion Site in accordance
with this section 26.5, all required permits have been issued and this Lease has
been amended in accordance with section 26.8.  Tenant shall  reimburse  Landlord
for actual  costs  expended  for review of all maps and plans.  Tenant shall not
materially  deviate from the Final Plans approved by Landlord without Landlord's
prior written  consent,  which shall not be  unreasonably  withheld.  Landlord's
approval of plans and specifications  shall not constitute the assumption of any
responsibility  by  Landlord  for  any  of  Tenant's  Work  or the  accuracy  or
sufficiency of Tenant's plans and specifications.

     (d) Immediately  upon  recordation of the Subdivision Map and completion of
all  procedures  necessary  to legally  subdivide  the  Premises,  Tenant  shall
purchase the Expansion Site from Landlord for a price (the "Site Price"), net to
Landlord,  equal to the  product of (i) the number of gross  square feet of land
area in the Expansion Site, multiplied by (ii) the Square Foot Price (as defined
below) in effect as of the date of the sale.  The term "Square Foot Price" means
(A) during the twelve (12) month period  commencing  on the  Commencement  Date,
seven and one-half  dollars ($7.50) (the "Initial  Price"),  and (B) during each
successive twelve (12) month period, the Initial Price increased by five percent
(5%) per year on a compounded  basis.  Tenant shall bear all costs and expenses,
and shall reimburse Landlord for all costs and expenses incurred by Landlord, in
connection with such purchase, including the subdivision of the Premises and the
Lease  Amendment.  After  the  recordation  of  the  Subdivision  Map  and  upon
completion of the sale of the Expansion Site to Tenant,  Tenant shall be subject
to no further  restriction  on encumbrance of the Expansion Site with a mortgage
or deed of trust.

     (e) If Tenant fails to commence  construction  of Tenant's work within nine
(9) months  after  delivery of the  Expansion  Notice or fails to  complete  the
Tenant's  Work in  accordance  with the Final  Plans  prior to the  Construction
Deadline,  Landlord, at Landlord's option, may rescind the sale of the Expansion
Site in which case the sale of the Expansion Site shall be reversed (with Tenant
conveying  the  Expansion  Site to  Landlord  at a net  price  equal to the Site
Price), and Tenant shall be deemed to have elected not to exercise the Expansion
Option.

     (f) Landlord and Tenant  acknowledge  that the  subdivision of the Premises
and  construction  of the Expansion  Improvements  will require  modification of
and/or additions to the parking facilities on the Premises.  Landlord and Tenant
shall include in the Final Plans provisions for parking  facilities serving both
the existing Building and the Expansion  Improvements.  Such parking  facilities
shall be designed and constructed at Tenant's sole cost and expense. If adequate
parking  facilities are not constructed on each respective  parcel sufficient to
serve that  parcel and it is  necessary  or  appropriate  to  construct  parking
facilities  on one of the  parcels to provide  parking  for both  parcels,  then
Landlord and Tenant shall enter into an appropriate perpetual access and parking
easement simultaneously with Tenant's purchase of the Expansion Site.

     26.6 In the event that Landlord elects not to undertake construction of the
Expansion  Improvements  or elects not to purchase  the  Expansion  Improvements
pursuant to section  26.3(a),  and Tenant  exercises the  Leasehold  Improvement
Option  and  elects to  undertake  construction  of the  Expansion  Improvements
("Tenant's Work"), the provisions of section 26.6(a) through 26.6(c) hereinbelow
shall be applicable.

     (a) Tenant shall cause to be  constructed  the  Expansion  Improvements  in
accordance  with all applicable  laws and the procedures set forth  hereinbelow.
Landlord  shall have no obligation to purchase the Expansion  Improvements,  and
Tenant shall,  for the remainder of the term, pay no Expansion Base Rent for the
Expansion  Improvements,  but the Expansion Improvements shall be deemed to be a
part of the Premises hereunder,  and Tenant shall pay all Operating Expenses for
the Expansion  Improvements as set forth in section 3.1(b) and shall perform all
other  obligations  of Tenant under this Lease as if the Expansion  Improvements
were  part of the  original  Premises.  At the  conclusion  of this  Lease,  the
Expansion  Improvements  shall  be  delivered  to  Landlord  in  good  condition
(reasonable wear and tear excepted).  Title to the Expansion Improvements shall,
at all  times,  remain in the name of  Landlord  and  shall not pass to  Tenant.
Landlord  shall  have no  liability  of any  kind,  and  Tenant  shall be solely
responsible,  for any  defects  or legal  violations  respecting  the  Expansion
Improvements in the event Tenant performs Tenant's Work. Tenant hereby agrees to
indemnify,  defend  and  hold  Landlord  harmless  from any and all  claims  and
liabilities  of  any  kind,   howsoever  arising,   relating  to  the  Expansion
Improvements and Tenant shall execute an indemnity,  reasonably  satisfactory to
Landlord in form and content, prior to commencement of Tenant's Work.

     (b) The design and  construction  of the  Expansion  Improvements  shall be
carried  out in  accordance  with the  terms  of  sections  26.3(a)(ii)  through
26.3(a)(ix),  all of which shall be applicable to Tenant's Work pursuant to this
section 26.6.

     (c)  Notwithstanding  that  Tenant  may  pay for  the  construction  of the
Expansion Improvements, if an Event of Default occurs, Landlord shall retain all
rights in law and equity against  Tenant,  including,  without  limitation,  the
right to dispossess Tenant from the Expansion  Improvements without compensation
for the cost thereof.

     26.7 Anything in this Article 26 to the contrary notwithstanding,  Tenant's
notice of exercise of the Expansion Option or the Tenant  Subdivision  Option or
the Leasehold Improvement Option shall be effective, only if at the time of such
notice of exercise the following  conditions (the "Expansion  Conditions") shall
be satisfied:

          (i) Landlord shall not have notified  Tenant that Tenant is in default
     in the performance of any of the terms,  covenants or conditions  contained
     in this Lease which default has not been cured within any applicable  grace
     period or cure period.
<PAGE>
                                       53


          (ii) This Lease  shall not have been  terminated  and shall be in full
     force and effect.

          (iii) There shall have been no assignment of Tenant's interest in this
     Lease except to a Corporate  Successor as permitted by section 12.1 hereof.
     Tenant  acknowledges  that the  Expansion  Option  and all other  rights of
     Tenant under this Article 26 are personal to Tenant, and not a right of any
     successor to the rights of Tenant under this Lease.

          (iv) There shall have been no material adverse change in the financial
     condition of Tenant or the Guarantor since the execution of this Lease, and
     Landlord shall determine,  at its sole reasonable  discretion,  that Tenant
     and Guarantor are each creditworthy in light of the obligations  undertaken
     pursuant  to this Lease and the other  existing  obligations  of Tenant and
     Guarantor.

     26.8 Notwithstanding anything to the contrary herein, promptly after Tenant
accepts the proposal in Landlord's  Specification  Notice, or Landlord elects to
purchase  the  Expansion  Improvements  pursuant to section  26.3(a),  or Tenant
exercises the Tenant Subdivision Option or the Leasehold  Improvement Option, as
the case may be, Landlord and Tenant shall enter into an amendment to this Lease
(the "Lease  Amendment")  setting  forth the terms of the expanded  lease or the
terms relating to Tenant's  Subdivision Option or Leasehold  Improvement Option,
in form and substance  mutually  agreeable to Landlord and Tenant which shall be
consistent with the applicable terms of this Article 26.

     IN WITNESS WHEREOF,  Landlord and Tenant have executed this Lease as of the
date first hereinabove written.

Landlord:                                Tenant:

                            CONTINUING LEASE GUARANTY


     THIS GUARANTY, made as of ___________ __, ____, by  _______________________
("Guarantor")  to TriNet  Essential  Facilities X, Inc., a Maryland  corporation
("Landlord").

                              W I T N E S S E T H:

     1. For valuable  consideration,  receipt of which is  acknowledged,  and to
satisfy  certain  requirements  under  the Lease  dated  January  15,  1998 (the
"Lease")  between  Landlord  and ICG  Holdings,  Inc.,  a  Colorado  corporation
("Tenant"),   Guarantor  hereby  absolutely,   unconditionally  and  irrevocably
guarantees to Landlord,  and agrees fully to pay, perform and discharge,  as and
when  payment,  performance  and  discharge  are  due,  all  of  the  covenants,
obligations  and  liabilities  of Tenant  under  the  Lease and all  amendments,
modifications, renewals, extensions, supplements, substitutions and replacements
of the Lease arising  during the period  beginning on the date hereof and ending
on the date this  Guaranty is terminated  (the  "Guaranteed  Obligations").  The
obligations of Guarantor  under this Guaranty  shall be absolute,  unconditional
and irrevocable and shall continue and remain in full force and effect until all
of the Guaranteed Obligations have been fully paid, performed and discharged.

     2. The  obligations of Guarantor under this Guaranty shall not be affected,
modified or impaired by the occurrence of any of the following  events,  whether
or not with notice to, or the consent of, Guarantor: (a) the waiver,  surrender,
compromise,  settlement,  release or termination of any or all of the Guaranteed
Obligations; (b) the failure to give notice to Guarantor of the occurrence of an
event of default under the Guaranteed Obligations; (c) the extension of the time
for  the  payment,  performance  or  discharge  of any or all of the  Guaranteed
Obligations;  (d) the amendment or modification  (whether material or otherwise)
of the Guaranteed Obligations in any respect; (e) any failure,  omission,  delay
or lack on the part of Landlord to enforce,  assert or exercise any right, power
or remedy  conferred  on  Landlord  under the  Guaranteed  Obligations;  (f) the
voluntary or involuntary liquidation,  dissolution, sale or other disposition of
all or substantially  all of the assets,  marshalling of assets and liabilities,
receivership,  insolvency,  bankruptcy, assignment for the benefit of creditors,
reorganization,  arrangement, composition with creditors or adjustment of debts,
or other similar proceedings  affecting Tenant or Guarantor or any of the assets
of either of them;  (g) the release or  discharge  by operation of law of Tenant
from the  payment,  performance  or  discharge  of any or all of the  Guaranteed
Obligations;  (h) the release or discharge by operation of law of Guarantor from
any or all of the  obligations  of  Guarantor  under this  Guaranty;  or (i) the
invalidity  or  unenforceability  of any or all of the  Guaranteed  Obligations.
Guarantor acknowledges that Landlord would not enter into the Lease without this
Guaranty and that Landlord is relying on this Guaranty.
<PAGE>
                                       2


     3. The  obligations of Guarantor under this Guaranty are independent of the
Guaranteed  Obligations.  Guarantor agrees that Landlord shall have the right to
proceed  against  Guarantor  directly and  independently  of Tenant.  A separate
action may be brought and prosecuted  against Guarantor whether or not an action
is  brought  against  Tenant or Tenant is joined in any such  action.  Guarantor
authorizes  Landlord and Tenant,  without  notice to, demand of, or consent from
Guarantor and without  releasing or affecting  Guarantor's  liability under this
Guaranty,  from time to time to amend,  modify,  renew,  extend,  supplement  or
replace  the  Guaranteed  Obligations  or  otherwise  change  the  terms  of the
Guaranteed   Obligations,   to  take  and  hold  security  for  the   Guaranteed
Obligations, and to enforce, waive, surrender, impair, compromise or release any
such  security  or any or all of the  Guaranteed  Obligations  or any  person or
entity liable for any or all of the Guaranteed  Obligations.  Guarantor shall be
and remain bound under this Guaranty notwithstanding any such act or omission by
Tenant or Landlord.  Guarantor  waives the right, if any, to require Landlord to
proceed  against  Tenant,  to proceed  against or exhaust any  security  held by
Landlord, or to pursue any other remedy in Landlord's power. Landlord shall have
the right to exercise or enforce any right or remedy  Landlord  may have against
Tenant or any security held by Landlord.  Guarantor waives the right, if any, to
the benefit of, or to direct the  application of, any security held by Landlord.
Guarantor  waives (a) any defense  arising out of any alteration of the original
Guaranteed Obligations,  (b) any defense arising out of the absence,  impairment
or loss of any right of reimbursement or subrogation or other right or remedy of
Guarantor  against Tenant or any security held by Landlord,  and (c) any defense
arising by reason of any  disability  or other defense of Tenant or by reason of
the cessation or reduction from any cause  whatsoever of the liability of Tenant
other  than  full  payment,   performance   and  discharge  of  the   Guaranteed
Obligations.  The  cessation  or  reduction  of the  liability of Tenant for any
reason  whatsoever  other than full  payment,  performance  and discharge of the
Guaranteed  Obligations  shall not release or affect in any way the liability of
Guarantor under this Guaranty.

     4. If  Tenant  becomes  insolvent  or is  adjudicated  bankrupt  or files a
petition for  reorganization,  arrangement,  composition or similar relief under
any present or future  provision of the federal  Bankruptcy  Code,  or if such a
petition is filed against  Tenant,  or if Tenant makes a general  assignment for
the  benefit  of  creditors,  and  in  any  such  proceeding  any  or all of the
Guaranteed  Obligations  are  terminated  or  rejected  or  any  or  all  of the
Guaranteed  Obligations  are modified or abrogated,  then Guarantor  agrees that
Guarantor's  liability  under this  Guaranty  shall not  thereby be  affected or
modified  and such  liability  shall  continue in full force and effect as if no
such action or proceeding  had  occurred.  This  Guaranty  shall  continue to be
effective or be reinstated, as the case may be, if any payment of the Guaranteed
Obligations  must be returned by Landlord  upon the  insolvency,  bankruptcy  or
reorganization of Tenant or Guarantor,  or otherwise, as though such payment had
not been made.
<PAGE>
                                       3


     5. Guarantor  assumes the  responsibility  for being and keeping  Guarantor
informed of the  financial  condition  of Tenant and of all other  circumstances
bearing  upon  the risk of  failure  to pay,  perform  or  discharge  any of the
Guaranteed Obligations which diligent inquiry would reveal, and Guarantor agrees
that Landlord has no duty to advise  Guarantor of information  known to Landlord
regarding such condition or any such circumstance.  Guarantor  acknowledges that
repeated and  successive  demands may be made and payments or  performance  made
hereunder  in response to such  demands as and when,  from time to time,  Tenant
defaults in the payment, performance or discharge of the Guaranteed Obligations.
Notwithstanding any such payments and performance hereunder, this Guaranty shall
remain  in full  force and  effect  and  shall  apply to any and all  subsequent
defaults  by Tenant.  It is not  necessary  for  Landlord  to  inquire  into the
capacity,  authority or powers of Tenant or the partners,  directors,  officers,
employees,  agents or  representatives  acting or purporting to act on behalf of
Tenant,  and all of the Guaranteed  Obligations made or created in reliance upon
the purported exercise of such powers shall be guaranteed under this Guaranty.

     6. If Tenant and Guarantor fail to pay, perform and discharge,  as and when
payment,  performance and discharge are due, all of the Guaranteed  Obligations,
Landlord shall have the right, but no obligation,  and without  releasing Tenant
or  Guarantor  from  any of the  Guaranteed  Obligations,  to pay,  perform  and
discharge  any or all of the  Guaranteed  Obligations  on behalf  of Tenant  and
Guarantor.  Guarantor  shall,  on demand,  pay to Landlord all sums  expended by
Landlord  in  the  payment,   performance   and  discharge  of  the   Guaranteed
Obligations,  together  with  interest  on  all  such  sums  from  the  date  of
expenditure  to the date  all such  sums are  paid by  Tenant  or  Guarantor  to
Landlord at the Interest  Rate (as defined in the Lease).  Guarantor  waives all
presentments,  demands for  performance,  notices of  nonperformance,  protests,
notices of  protest,  notices of  dishonor  and  notices of  acceptance  of this
Guaranty.  Guarantor agrees to pay all costs and expenses,  including reasonable
attorneys'  fees and  disbursements,  which  are  incurred  by  Landlord  in the
enforcement  of this  Guaranty.  If any provision of this Guaranty is held to be

                            CONTINUING LEASE GUARANTY

     THIS GUARANTY, made as of January 20, 1998, by ICG COMMUNICATIONS,  INC., a
Delaware  corporation  ("Guarantor") to TRINET  ESSENTIAL  FACILITIES X, INC., a
Maryland corporation ("Landlord").

                              W I T N E S S E T H:

     1. For valuable  consideration,  receipt of which is  acknowledged,  and to
satisfy  certain  requirements  under  the Lease  dated  January  15,  1998 (the
"Lease")  between  Landlord  and ICG  Holdings,  Inc.,  a  Colorado  corporation
("Tenant"),   Guarantor  hereby  absolutely,   unconditionally  and  irrevocably
guarantees to Landlord,  and agrees fully to pay, perform and discharge,  as and
when  payment,  performance  and  discharge  are  due,  all  of  the  covenants,
obligations  and  liabilities  of Tenant  under  the  Lease and all  amendments,
modifications, renewals, extensions, supplements, substitutions and replacements
of the Lease arising  during the period  beginning on the date hereof and ending
on the date this  Guaranty is terminated  (the  "Guaranteed  Obligations").  The
obligations of Guarantor  under this Guaranty  shall be absolute,  unconditional
and irrevocable and shall continue and remain in full force and effect until all
of the Guaranteed Obligations have been fully paid, performed and discharged.

     2. The  obligations of Guarantor under this Guaranty shall not be affected,
modified or impaired by the occurrence of any of the following  events,  whether
or not with notice to, or the consent of, Guarantor: (a) the waiver,  surrender,
compromise,  settlement,  release or termination of any or all of the Guaranteed
Obligations; (b) the failure to give notice to Guarantor of the occurrence of an
event of default under the Guaranteed Obligations; (c) the extension of the time
for  the  payment,  performance  or  discharge  of any or all of the  Guaranteed
Obligations;  (d) the amendment or modification  (whether material or otherwise)
of the Guaranteed Obligations in any respect; (e) any failure,  omission,  delay
or lack on the part of Landlord to enforce,  assert or exercise any right, power
or remedy  conferred  on  Landlord  under the  Guaranteed  Obligations;  (f) the
voluntary or involuntary liquidation,  dissolution, sale or other disposition of
all or substantially  all of the assets,  marshalling of assets and liabilities,
receivership,  insolvency,  bankruptcy, assignment for the benefit of creditors,
reorganization,  arrangement, composition with creditors or adjustment of debts,
or other similar proceedings  affecting Tenant or Guarantor or any of the assets
of either of them;  (g) the release or  discharge  by operation of law of Tenant
from the  payment,  performance  or  discharge  of any or all of the  Guaranteed
Obligations;  (h) the release or discharge by operation of law of Guarantor from
any or all of the  obligations  of  Guarantor  under this  Guaranty;  or (i) the
invalidity  or  unenforceability  of any or all of the  Guaranteed  Obligations.
Guarantor acknowledges that Landlord would not enter into the Lease without this
Guaranty and that Landlord is relying on this Guaranty.

                                       2


     3. The  obligations of Guarantor under this Guaranty are independent of the
Guaranteed  Obligations.  Guarantor agrees that Landlord shall have the right to
proceed  against  Guarantor  directly and  independently  of Tenant.  A separate
action may be brought and prosecuted  against Guarantor whether or not an action
is  brought  against  Tenant or Tenant is joined in any such  action.  Guarantor
authorizes  Landlord and Tenant,  without  notice to, demand of, or consent from
Guarantor and without  releasing or affecting  Guarantor's  liability under this
Guaranty,  from time to time to amend,  modify,  renew,  extend,  supplement  or
replace  the  Guaranteed  Obligations  or  otherwise  change  the  terms  of the
Guaranteed   Obligations,   to  take  and  hold  security  for  the   Guaranteed
Obligations, and to enforce, waive, surrender, impair, compromise or release any
such  security  or any or all of the  Guaranteed  Obligations  or any  person or
entity liable for any or all of the Guaranteed  Obligations.  Guarantor shall be
and remain bound under this Guaranty notwithstanding any such act or omission by
Tenant or Landlord.  Guarantor  waives the right, if any, to require Landlord to
proceed  against  Tenant,  to proceed  against or exhaust any  security  held by
Landlord, or to pursue any other remedy in Landlord's power. Landlord shall have
the right to exercise or enforce any right or remedy  Landlord  may have against
Tenant or any security held by Landlord.  Guarantor waives the right, if any, to
the benefit of, or to direct the  application of, any security held by Landlord.
Guarantor  waives (a) any defense  arising out of any alteration of the original
Guaranteed Obligations,  (b) any defense arising out of the absence,  impairment
or loss of any right of reimbursement or subrogation or other right or remedy of
Guarantor  against Tenant or any security held by Landlord,  and (c) any defense
arising by reason of any  disability  or other defense of Tenant or by reason of
the cessation or reduction from any cause  whatsoever of the liability of Tenant
other  than  full  payment,   performance   and  discharge  of  the   Guaranteed
Obligations.  The  cessation  or  reduction  of the  liability of Tenant for any
reason  whatsoever  other than full  payment,  performance  and discharge of the
Guaranteed  Obligations  shall not release or affect in any way the liability of
Guarantor under this Guaranty.

     4. If  Tenant  becomes  insolvent  or is  adjudicated  bankrupt  or files a
petition for  reorganization,  arrangement,  composition or similar relief under
any present or future  provision of the federal  Bankruptcy  Code,  or if such a
petition is filed against  Tenant,  or if Tenant makes a general  assignment for
the  benefit  of  creditors,  and  in  any  such  proceeding  any  or all of the
Guaranteed  Obligations  are  terminated  or  rejected  or  any  or  all  of the
Guaranteed  Obligations  are modified or abrogated,  then Guarantor  agrees that
Guarantor's  liability  under this  Guaranty  shall not  thereby be  affected or
modified  and such  liability  shall  continue in full force and effect as if no
such action or proceeding  had  occurred.  This  Guaranty  shall  continue to be
effective or be reinstated, as the case may be, if any payment of the Guaranteed
Obligations  must be returned by Landlord  upon the  insolvency,  bankruptcy  or
reorganization of Tenant or Guarantor,  or otherwise, as though such payment had
not been made.
<PAGE>
                                       3


     5. Guarantor  assumes the  responsibility  for being and keeping  Guarantor
informed of the  financial  condition  of Tenant and of all other  circumstances
bearing  upon  the risk of  failure  to pay,  perform  or  discharge  any of the
Guaranteed Obligations which diligent inquiry would reveal, and Guarantor agrees
that Landlord has no duty to advise  Guarantor of information  known to Landlord
regarding such condition or any such circumstance.  Guarantor  acknowledges that
repeated and  successive  demands may be made and payments or  performance  made
hereunder  in response to such  demands as and when,  from time to time,  Tenant
defaults in the payment, performance or discharge of the Guaranteed Obligations.
Notwithstanding any such payments and performance hereunder, this Guaranty shall
remain  in full  force and  effect  and  shall  apply to any and all  subsequent
defaults  by Tenant.  It is not  necessary  for  Landlord  to  inquire  into the
capacity,  authority or powers of Tenant or the partners,  directors,  officers,
employees,  agents or  representatives  acting or purporting to act on behalf of
Tenant,  and all of the Guaranteed  Obligations made or created in reliance upon
the purported exercise of such powers shall be guaranteed under this Guaranty.

     6. If Tenant and Guarantor fail to pay, perform and discharge,  as and when
payment,  performance and discharge are due, all of the Guaranteed  Obligations,
Landlord shall have the right, but no obligation,  and without  releasing Tenant
or  Guarantor  from  any of the  Guaranteed  Obligations,  to pay,  perform  and
discharge  any or all of the  Guaranteed  Obligations  on behalf  of Tenant  and
Guarantor.  Guarantor  shall,  on demand,  pay to Landlord all sums  expended by
Landlord  in  the  payment,   performance   and  discharge  of  the   Guaranteed
Obligations,  together  with  interest  on  all  such  sums  from  the  date  of
expenditure  to the date  all such  sums are  paid by  Tenant  or  Guarantor  to
Landlord at the Interest  Rate (as defined in the Lease).  Guarantor  waives all
presentments,  demands for  performance,  notices of  nonperformance,  protests,
notices of  protest,  notices of  dishonor  and  notices of  acceptance  of this
Guaranty.  Guarantor agrees to pay all costs and expenses,  including reasonable
attorneys'  fees and  disbursements,  which  are  incurred  by  Landlord  in the
enforcement  of this  Guaranty.  If any provision of this Guaranty is held to be
invalid or unenforceable, the validity or enforceability of the other provisions
of this Guaranty shall not be affected. If there is more than one Guarantor, all
obligations  of  Guarantor  under this  Guaranty  shall be the joint and several
obligations of each  Guarantor.  This Guaranty may not be amended or modified in
any respect except by a written instrument signed by Guarantor and Landlord.  As
used in this  Guaranty,  the singular  shall  include the plural.  This Guaranty
shall  bind and  inure to the  benefit  of  Guarantor  and  Landlord  and  their
respective transferees, personal representatives, heirs, successors and assigns.
This Guaranty shall be governed by and construed in accordance  with the laws of
the  State  where the  premises  leased by Tenant  from  Landlord  are  located.
Guarantor hereby irrevocably  consents to the non-exclusive  jurisdiction of the
courts of the States of Colorado  and  California  and any federal  court of the
United States of America  located in the City of San Francisco,  California,  or
the city of Denver,  Colorado.  Guarantor  and Landlord  each waive any right to
trial by jury in connection  herewith.  Without limiting anything else contained
herein,  the  fullest  extent it may  effectively  do so under  applicable  law,
Guarantor  irrevocably  waives and agrees not to assert,  by way of motion, as a
defense or otherwise,  any claim that it is not subject to the  jurisdiction  of
any such court, any objection that it may now or hereafter have to the laying of
the venue of any such suit,  action or proceeding  brought in any such court and
any claim that any such suit, action or proceeding brought in any such court has
been brought in an inconvenient forum.

     7. To induce  Landlord to enter into the Lease,  Guarantor  represents  and
warrants to Landlord as follows:  Guarantor is a corporation  existing under the
laws of the State of Delaware.  Guarantor  has full power and authority to enter
into this  Guaranty  and to perform its  obligations  under this  Guaranty.  The
execution, delivery and performance of this Guaranty by Guarantor have been duly

affecting the rights of creditors generally.  Neither the execution and delivery
of this Guaranty nor the  consummation of the transactions  contemplated  hereby
will conflict with, or (with or without notice or lapse of time, or both) result
in a termination,  breach, impairment or violation of, or give rise to a default
under (i) any provision of Guarantor's articles of incorporation or bylaws, (ii)

satisfy  certain  requirements  under  the Lease  dated  January  15,  1998 (the
"Lease")  between  Landlord  and ICG  Holdings,  Inc.,  a  Colorado  corporation

of the Lease arising  during the period  beginning on the date hereof and ending

     3. The  obligations of Guarantor under this Guaranty are independent of the
Guaranteed  Obligations.  Guarantor agrees that Landlord shall have the right to
proceed  against  Guarantor  directly and  independently  of Tenant.  A separate
action may be brought and prosecuted  against Guarantor whether or not an action
is  brought  against  Tenant or Tenant is joined in any such  action.  Guarantor
authorizes  Landlord and Tenant,  without  notice to, demand of, or consent from
Guarantor and without  releasing or affecting  Guarantor's  liability under this
Guaranty,  from time to time to amend,  modify,  renew,  extend,  supplement  or
replace  the  Guaranteed  Obligations  or  otherwise  change  the  terms  of the
Guaranteed   Obligations,   to  take  and  hold  security  for  the   Guaranteed
Obligations, and to enforce, waive, surrender, impair, compromise or release any
such  security  or any or all of the  Guaranteed  Obligations  or any  person or
entity liable for any or all of the Guaranteed  Obligations.  Guarantor shall be
and remain bound under this Guaranty notwithstanding any such act or omission by
Tenant or Landlord.  Guarantor  waives the right, if any, to require Landlord to
proceed  against  Tenant,  to proceed  against or exhaust any  security  held by
Landlord, or to pursue any other remedy in Landlord's power. Landlord shall have
the right to exercise or enforce any right or remedy  Landlord  may have against
Tenant or any security held by Landlord.  Guarantor waives the right, if any, to
the benefit of, or to direct the  application of, any security held by Landlord.
Guarantor  waives (a) any defense  arising out of any alteration of the original
Guaranteed Obligations,  (b) any defense arising out of the absence,  impairment
or loss of any right of reimbursement or subrogation or other right or remedy of
Guarantor  against Tenant or any security held by Landlord,  and (c) any defense
arising by reason of any  disability  or other defense of Tenant or by reason of
the cessation or reduction from any cause  whatsoever of the liability of Tenant
other  than  full  payment,   performance   and  discharge  of  the   Guaranteed
Obligations.  The  cessation  or  reduction  of the  liability of Tenant for any
reason  whatsoever  other than full  payment,  performance  and discharge of the
Guaranteed  Obligations  shall not release or affect in any way the liability of
Guarantor under this Guaranty.

     4. If  Tenant  becomes  insolvent  or is  adjudicated  bankrupt  or files a
petition for  reorganization,  arrangement,  composition or similar relief under
any present or future  provision of the federal  Bankruptcy  Code,  or if such a
petition is filed against  Tenant,  or if Tenant makes a general  assignment for
the  benefit  of  creditors,  and  in  any  such  proceeding  any  or all of the
Guaranteed  Obligations  are  terminated  or  rejected  or  any  or  all  of the
Guaranteed  Obligations  are modified or abrogated,  then Guarantor  agrees that
Guarantor's  liability  under this  Guaranty  shall not  thereby be  affected or
modified  and such  liability  shall  continue in full force and effect as if no
such action or proceeding  had  occurred.  This  Guaranty  shall  continue to be
effective or be reinstated, as the case may be, if any payment of the Guaranteed
Obligations  must be returned by Landlord  upon the  insolvency,  bankruptcy  or
reorganization of Tenant or Guarantor,  or otherwise, as though such payment had
not been made.

Landlord shall have the right, but no obligation,  and without  releasing Tenant
or  Guarantor  from  any of the  Guaranteed  Obligations,  to pay,  perform  and

Landlord  in  the  payment,   performance   and  discharge  of  the   Guaranteed
Obligations,  together  with  interest  on  all  such  sums  from  the  date  of

of this Guaranty shall not be affected. If there is more than one Guarantor, all
obligations  of  Guarantor  under this  Guaranty  shall be the joint and several
obligations of each  Guarantor.  This Guaranty may not be amended or modified in
any respect except by a written instrument signed by Guarantor and Landlord.  As

This Guaranty shall be governed by and construed in accordance  with the laws of
the  State  where the  premises  leased by Tenant  from  Landlord  are  located.
Guarantor hereby irrevocably  consents to the non-exclusive  jurisdiction of the
courts of the States of Colorado  and  California  and any federal  court of the
United States of America  located in the City of San Francisco,  California,  or
the city of Denver,  Colorado.  Guarantor  and Landlord  each waive any right to

herein,  the  fullest  extent it may  effectively  do so under  applicable  law,
Guarantor  irrevocably  waives and agrees not to assert,  by way of motion, as a
defense or otherwise,  any claim that it is not subject to the  jurisdiction  of
