ITEM 1. BUSINESS
 
    Certain statements under this caption "Business" constitute "forward-looking
statements" under the Reform Act.
 
GENERAL
 
    MFN is a facilities-based provider of technologically advanced,
high-bandwidth, fiber optic communications infrastructure to carrier and
corporate/government customers. The Company is expanding its existing network to
encompass in excess of 229,000 fiber miles, or in excess of 650 route miles,
concentrated in the northeastern United States, a market which the Company
believes is characterized by significant demand for and limited supply of fiber
optic capacity. The fiber infrastructure leased by MFN to its customers provides
high-bandwidth capacity for customers that seek to establish secure
communications networks for the transmission of large amounts of voice, data and
video. For example, a pair of MFN fiber optic strands can transmit up to 8.6
gigabits of data per second or the equivalent of approximately 129,000
simultaneous voice conversations.
 
    The Company tailors the amounts of capacity leased to the needs of its
customers. Certain customers that lease fiber optic capacity from the Company
connect their own transmission equipment to the leased fiber, thereby obtaining
a fixed-cost, secure telecommunications alternative to the metered
communications services offered by traditional providers. Other customers that
require lesser amounts of transmission capacity will have the option to lease
such broadband capacity on the Company's network, whereby the Company
effectively divides a single strand of fiber into multiple smaller
communications channels. The
 
                                       3
<PAGE>
Company believes that it will have installation, operating, and maintenance cost
advantages per fiber mile relative to its competitors because MFN installs its
network with as many as 432 fibers per route mile as compared to a generally
lower number of fibers in existing competitive networks.
 
    The Company was formed in 1993 and currently possesses a fiber optic
communications network in the New York/New Jersey metropolitan area (the "NY
Network") and has infrastructure and will commence operations in the Chicago
metropolitan area, consisting of more than 30,000 fiber miles. Within the next
eighteen months the Company plans to complete an expansion of the NY Network to
increase its coverage within the New York/New Jersey metropolitan area. In
addition, the Company intends to construct intra-city fiber optic networks in
Washington, D.C., Chicago and Philadelphia and an inter-city fiber optic route
between New York City and Washington, D.C. The Company currently intends to
expand its network in order to connect the NY Network with other major domestic
metropolitan areas, in part through the exchange of fiber capacity with other
carriers and through other arrangements. The Company has also entered into a
50/50 joint venture, International Optical Network, L.L.C. ("ION"), with a
subsidiary of Racal Electronics Plc, a United Kingdom manufacturer of
electronics and other equipment and a provider of telecommunications services in
the U.K. ION will provide managed transatlantic network services by linking the
Company's network to London by acquiring transatlantic fiber optic cable rights
linking points of presence in the US and UK. ION will enable the Company to
offer its customers seamless broadband connectivity between New York and other
cities served by MFN and London. See "--Build-out of Networks." The Company's NY
Network supports a self-healing SONET architecture that minimizes the risk of
downtime in the event of a fiber cut and provides MFN's customers with high
security and reliability. It is expected that the Company's other intra-city
networks will also support a self-healing SONET architecture. Most of the
Company's fiber is installed inside high density polyethylene conduit to protect
the cable and, where practicable, MFN installs additional unused conduits to
accommodate future network expansion.
 
    MFN is focused on providing its broadband communications infrastructure to
two main customer groups: communications carriers and corporate/government
customers located in selected Tier I markets (generally, the top cities in the
United States based on population). Carrier customers targeted by the Company
include a broad range of communications companies such as incumbent local
exchange carriers ("ILECs"), competitive local exchange carriers ("CLECs"), long
distance companies/interexchange carriers ("IXCs"), paging, cellular and PCS
companies, cable companies, and Internet service providers ("ISPs"). These
carrier customers typically would lease fiber optic capacity with which they
would develop their own communications networks as a low-cost alternative to
building their own infrastructure or purchasing metered services from ILECs or
CLECs. The Company's corporate and government customers would typically lease
fiber optic infrastructure and other broadband services on a point-to-point
basis for high-bandwidth, secure voice and data networks. The Company believes
that it will be well-positioned to penetrate the corporate and government
markets since it plans to continue to install most of its fiber in Tier I
markets. See "--Customers."
 
    On April 30, 1997, Metromedia Company ("Metromedia") and certain of its
affiliates made a substantial equity investment in the Company (the "Metromedia
Investment"). Metromedia and its partners own all of the outstanding shares of
Class B Common Stock of the Company, par value $.01 per share (the "Class B
Common Stock"), which is entitled to 10 votes per share and to vote separately
to elect at least 75% of the members of the Board of Directors. As a result,
Metromedia and its partners own and control approximately 18.26% of the common
equity of the Company (on a diluted basis) and approximately 69% of the
outstanding voting power (on a diluted basis). On October 28, 1997, the Company
successfully completed its initial public offering of 9,108,000 shares of Class
A Common Stock (the "Offering") generating proceeds to the Company of $135.5
million (deducting underwriting discounts but not deducting offering expenses).

Operations" and "Item 8. Financial Statements and Supplementary Data" of this
Form 10-K.
 
BUILD-OUT OF NETWORKS
 
    Since its founding in 1993 the Company has mostly concentrated on developing
and constructing its NY Network. The Company has developed a plan for the
expansion of the NY Network and the construction of new fiber optic intra-city
telecommunications networks in Washington, D.C., Chicago and Philadelphia (the
"Intra-City Networks") and fiber optic backbone between New York City and
Washington, D.C. (the "Inter-City Networks") and is pursuing the acquisition of
necessary licenses, franchises and rights-of-way. In constructing its fiber
optic networks, the Company seeks to create strategic alliances with the
engineering and construction management firms that have been engaged to develop
routes, easements and manage deployment plans. Firms with whom the Company is
allied in this regard have deployed local loop network infrastructure for RBOCs
as well as for CLECs. Though much of the actual construction will be outsourced
to various construction firms, the Company maintains strict oversight of the
design and implementation of its fiber optic communications networks. The
Company utilizes only advanced commercially available fiber. Although the
Company has ordered a substantial portion of its fiber optic cable from Lucent
Technologies, Inc., it believes that it could obtain advanced fiber from other
suppliers on acceptable terms.
 
    The Company intends to finance the completion of the build-out of its
networks through the use of cash on hand, revenues generated from the sale of
capacity on its networks including substantial up front payments for certain
long term leases and rights to use agreements.
 
    NY NETWORK.  The NY Network currently consists of an over 100 route mile
fiber optic communications network in the New York/New Jersey metropolitan area
consisting of more than 27,000 fiber miles. As currently planned, upon
completion the NY Network will be in excess of 180 route miles with each
additional route-mile consisting of up to 432 fibers for a network total in
excess of 60,000 fiber miles. Upon its completion, the entire NY Network will
create a SONET capable fiber ring focused in Manhattan and extending into each
of the other four boroughs, as well as east to Brookhaven, Suffolk County, Long
Island, north to White Plains, Westchester County and west to Northern and
Central New Jersey. The expanded NY Network is expected to pass more than 800
buildings in New York City and to pass through 31 RBOC central offices, which
are believed to connect to over 15 million people and over 400,000 businesses.
On September 19, 1997, the Company entered into a twenty-year fiber swap
arrangement with an engineering and telecommunications infrastructure
construction company which provides the Company with access to approximately
7,760 fiber miles (or 38.8 route miles) in the New York/New Jersey metropolitan
area in return for the Company providing access to 21.9 route miles on its NY
Network. The agreement also gives the Company the right to acquire a twenty-year
indefeasible right to use an additional 7,756 fiber miles and duct for MFN to
place its own fibers in the New York/New Jersey metropolitan area in return for
certain monthly payments.
 
    INTRA-CITY NETWORKS.  Subject to the receipt of the necessary franchises,
licenses and rights-of-way, the Company plans to construct additional fiber
optic communications networks in Washington, D.C., Chicago, and Philadelphia. No
assurance can be given that the necessary franchises, licenses and rights of way
will be obtained or consummated or will provide all of the rights needed to
implement the Company's
 
                                       5

    INTER-CITY NETWORK.  Subject to the receipt of the necessary franchises,
licenses and rights-of-way, the Company plans to construct and operate its
Inter-City Network between New York City and Washington, D.C., covering
approximately 114,000 fiber miles (or 264 route miles). The Company has
completed or is in the process of negotiating for the acquisition of related
rights-of-way.
 
    RIGHTS-OF-WAY.  When the Company decides to build a fiber optic
communications network, its corporate development staff seeks to obtain the
necessary rights of way and governmental authorizations. In some jurisdictions,
a construction permit is all that is required. In other jurisdictions, a license
agreement or franchise is also required. Such licenses and franchises are
generally for a term of limited duration. Where possible, rights-of-way are
leased under multi-year agreements with renewal options and are generally
non-exclusive. The Company strives to obtain rights-of-way that afford it the
opportunity to expand its communications networks as business develops.
 
    The Company plans to lease underground conduit and pole space and other
rights-of-way from entities such as ILECs, utilities, railroads, IXCs, state
highway authorities, local governments and transit authorities.
 
    The following is a summary of the status of MFN's efforts to secure
rights-of-way:
 
    - NEW YORK CITY: A franchise agreement entered into between the Company and
      the City of New York on December 20, 1993 (the "NYC Franchise Agreement")
      grants MFN the right, until December 2008, to install, operate, repair,
      maintain, remove and replace cable, wire, fiber or other transmission
      media that may be used in lieu of cable, wire or fiber on, over and under
      the inalienable property of New York City in order to provide
      telecommunications services which originate and/or terminate in or transit
      New York City. The Conduit Occupancy Agreement (as defined herein) between
      the Company and Bell Atlantic, together with easements granted to the
      Company by Bell Atlantic's subsidiary, Empire City Subway (Ltd.) ("ECS"),
      authorize the installation of the Company's fiber optic communications
      network in Bell Atlantic's conduit system and the conduit system
      associated with the ECS, respectively. See "--Franchise, License and
      Related Agreements--New York City Franchise Agreement" and "--Conduit
      Occupancy Agreement."
 
    - CHICAGO: MFN has entered into agreements which will provide the Company
      with access to more than 4300 fiber miles along in excess of 40 miles of
      infrastructure on key routes within its Chicago market, in addition to the
      necessary easements and rights-of-way for its Chicago network. MFN is also
      investigating procuring the required franchises, licenses, permits and
      other agreements needed to complete its Chicago network.
 
    - WASHINGTON, D.C.: The Company has obtained rights-of-way for a portion of
      the Washington, D.C. Intra-City Network and is investigating obtaining the
      necessary licenses and permits for this network.
 
    - PHILADELPHIA: MFN has negotiated with the City of Philadelphia for
      permission, subject to certain conditions, to construct, maintain and
      operate, replace and remove a telecommunications system in, under and
      across the public rights-of-way and city streets and/or to place such
      telecommunications system within the existing facilities owned by Bell
      Atlantic Corporation, PECO Energy Company,
 
                                       6
<PAGE>
      Southeastern Pennsylvania Transportation Authority, Consolidated Rail
      Corporation or any other entity holding a grant pursuant to City
      ordinances. An appropriate ordinance was passed by the Philadelphia city
      council in June 1997 and the Company expects to enter into formal licenses
      and other agreements shortly.
 
    In developing the Inter-City Network, MFN has negotiated with certain rail
transportation providers to accomplish the Company's goal of providing its
customers with a flexible network architecture. Design and planning is underway
and the Company soon will start construction of this route.
 
TECHNOLOGY
 
    The MFN Network consists of fiber optic communication paths which allow for
high speed, high quality transmission of voice, data and video communications.
Fiber optic systems use laser-generated light to transmit voice, data and video
in digital formats through ultra-thin strands of glass. Fiber optic systems are
generally characterized by large circuit capacity, good sound quality,
resistance to external signal interference and direct interface to digital
switching equipment or digital microwave systems. The Company plans to install
backbone fiber optic cables containing up to 432 fiber optic strands, which have
significantly greater bandwidth than traditional analog copper cables. Using
current electronic transmitting devices, a single pair of glass fibers used by
the Company's network can transmit up to 8.6 gigabits of data per second or the
equivalent of approximately 129,000 simultaneous voice conversations, which is
substantially more than traditional analog copper cable installed in many
current communications networks. The Company believes that continuing
developments in compression technology and multiplexing equipment will increase
the capacity of each fiber optic strand, thereby providing more bandwidth
carrying capacity at relatively low incremental costs. The Company's network is
capable of using the highest commercially available capacity transmission
(OC-192) and thereby can handle advanced, capacity-intensive data applications
such as Frame Relay, ATM, multimedia and Internet-related applications.
 
    The Company offers end-to-end fiber optic capacity, capable of utilizing
SONET capable ring architecture, which has the ability to route customer traffic
in either direction around its ring design thereby assuring that fiber cuts do
not interrupt service to customers on the NY Network and its planned Intra-City
Networks. The Company's Network is also capable of supporting DWDM (dense wave
division multiplexing), ATM and gigabit ethernet. Currently, a state-of-the-art
network operating system continuously monitors and maintains quality control of
the NY Network on a 24-hour basis and alerts the Company of any degradation or
loss of fiber capacity, pinpoints the location of such degradation and enables
the Company to repair or replace impaired fiber without any loss of service. In
addition, the monitoring system automatically reroutes traffic in the event of a
catastrophic break in the system, enabling the Company to ensure that its
customers obtain continuous service.
 
FRANCHISE, LICENSE AND RELATED AGREEMENTS
 
    NEW YORK CITY FRANCHISE AGREEMENT.  The Company has entered into a 15 year
non-exclusive franchise agreement with New York City, which expires in December
2008, to install, operate, repair, maintain, remove and replace cable, wire,
fiber or other transmission medium that may be used in lieu of cable, wire or
fiber on, over and under the inalienable property of New York City in order to
provide telecommunications services which originate and/or terminate in or
transit New York City. The NYC Franchise Agreement provides that the Company may
submit a written petition to New York City to renew the term of the franchise at
least 12 months (but not more than 18 months) before the expiration of the 15
year term. However, New York City has no obligation to renew the NYC Franchise
Agreement. The City of New York has granted only seven franchises to date.
However, the Company is not aware of any limit on the number of franchises that
the City of New York may grant and believes that the City of New York has begun
the process that will result in the awarding of additional licenses.
 
                                       7
<PAGE>
    The NYC Franchise Agreement requires the Company to provide New York City
with certain telecommunications infrastructure and, by November 1999, to
complete construction of its initial network as described in the NYC Franchise
Agreement. The Company believes it is on schedule to complete such construction.
 
    Both New York City and the Company have the right, at any one time after
December 20, 2000, upon six months notice, to renegotiate certain terms of the
NYC Franchise Agreement, including the annual compensation payable by the
Company to New York City, based on changes in technological, regulatory or
market conditions which may occur after the effective date of the NYC Franchise
Agreement. In the event either party calls for renegotiation, both New York City
and the Company are required to negotiate any such changes in good faith. In the
event an agreement cannot be reached upon any such renegotiation, the NYC
Franchise Agreement will be subject to early termination on a date which would
be one half of the number of days between the date of the notice to renegotiate
and January 1, 2009.
 
    The Company was required to pay the City of New York an annual franchise fee
at a rate of 10% of Gross Revenues per year for 1995 and 1996, 6% of Gross
Revenues for 1997, currently pays 5% of Gross Revenues in 1998 and will pay 5%
of Gross Revenues for each remaining year of the franchise. "Gross Revenues" is
defined in the NYC Franchise Agreement as all revenues received directly or
indirectly by the Company or any affiliate of the Company from or in connection
with telecommunications services which originate in, terminate in, or transit
New York City. Revenues that are generated from transmissions which transit New
York City, but also include transmission through other areas, are to be
pro-rated. The minimum franchise fee payable to the City of New York is $200,000
per annum.
 
    The NYC Franchise Agreement requires that the consent of the City of New
York be obtained in connection with the acquisition of 5% or more of the shares
of the Company by any person other than Mr. Stephen A. Garofalo, Metromedia, Mr.
Howard M. Finkelstein or Mr. Peter Sahagen or any other 5% stockholder on the
date of the consummation of the Offering. Accordingly, the City of New York
would need to consent to the acquisition by any person of more than 5% of the
Class A Common Stock.
 
    CONDUIT OCCUPANCY AGREEMENT.  The Company entered into a non-exclusive
conduit occupancy agreement (the "Conduit Occupancy Agreement") with Bell
Atlantic in May 1993, authorizing the Company to install its cable facilities in
Bell Atlantic's conduit system in New York. The Company is required to pay Bell
Atlantic certain rates and charges pursuant to the terms of the agreement.
 
    The Conduit Occupancy Agreement, which had an initial term of 12 months but
was to continue indefinitely if not affirmatively terminated by either party, is
terminable without cause by either party upon three months' written notice.
Under certain circumstances, a petition may be brought to the Public Services
Commission requesting that it decide a dispute arising over termination prior to
the termination of the Conduit Occupancy Agreement.
 
SALES AND MARKETING
 
    The Company's sales and marketing strategy includes (i) positioning itself
as the communications carriers' carrier of choice, (ii) focusing on high dollar
volume corporate and government customers and (iii) emphasizing the cost
advantages which will allow the Company to lease its fiber optic infrastructure
at fixed prices which represent potentially significant savings for its large
volume carrier and corporate customers relative to their present build or buy
alternatives. The Company also believes that communications carriers and
corporate and government customers will be attracted to the Company's dark fiber
product and its unmetered pricing structure. (Dark fiber is installed fiber
optic cable which is not otherwise carrying a signal originated by the service
provider (i.e., MFN), but which will carry a signal generated by the customer.)
The Company intends to focus its sales and marketing efforts on carrier
customers. However, the Company is currently in the process of hiring additional
sales professionals to focus on both customer groups. As MFN constructs fiber
optic networks in new cities, local sales professionals are expected to be hired
to target regional corporate, government and carrier customers.
 
                                       8

CUSTOMERS
 
    CARRIERS.  The Company expects that communications carriers will account for
a majority of its business. The Company currently targets the major carriers,
such as resellers, data services, RBOCs, IXCs, CLECs, ISPs, wireless providers,
and major information service providers. The Company believes it can compete
effectively with other providers due to its rapid deployment, pricing,
reliability, customer service and capacity of the MFN Network. The Company
traditionally leases dark fiber to communications carriers, providing them with
point-to-point and IXC point of presence ("POP") to end user non-switched
access, which connects their customers to the Company's network, enabling them
to eliminate or reduce costly access charges.
 
    The Company has entered into contracts with several communications carriers,
including providers of wireless, cellular, interexchange and competitive local
exchange services. In addition, the Company is currently in the process of
negotiating agreements with certain other major communications carriers and will
continue to target such carriers in the future.
 
    On June 3, 1997, the Company entered into an agreement with NextLink New
York, L.L.C. ("NextLink"), a CLEC, that provides certain exclusive long-term
rights to certain fiber strands in the NY Network. The agreement calls for MFN
to provide NextLink with capacity over a portion of MFN's network at specified
locations for twenty years (the "Term"), with an additional ten year option
exercisable by the customer. In addition, the agreement permits the carrier to
use additional fiber miles for additional charges and requires, under certain
circumstances, the Company to construct and maintain extensions of up to two
miles from the then-existing network. As compensation through the Term, the
Company is to receive $11.0 million in scheduled upfront payments, a monthly
recurring charge per terminated fiber strand terminating at certain additional
locations, and an additional fiber charge per mile of additional fiber made
available for the customer. Charges for the term of the option period are to be
determined at market rates prevailing at the time the option is exercised.
 
    In April 1996, the Company entered into an agreement with U.S. One
Communications ("U.S. One"), an IXC, pursuant to which it leases portions of its
fiber optic network to U.S. One for an initial term lasting until December 20,
2008. U.S. One has the option to renew the agreement for an additional term of
up to 13 years. Lease payments consisted of prepayments of $3.6 million. Lease
payments for the additional term are payable only if U.S. One elects to renew
the agreement, either monthly at a rate per fiber mile equal to the lowest lease
rate charged by the Company to any lessee or in a lump sum payment equal to the
present value of the lease payments, up to a maximum of $8.8 million plus a
certain percentage based upon the consumer price index. The lump sum payment to
be made by U.S. One is subject to adjustment if the Company has not completed
the build-out of a portion of its network. During 1997 U.S. One was acquired by
Winstar Communications.
 
    In February 1998, the Company entered into an agreement with an affiliate of
NextLink to provide certain rights to multiple fibers and innerducts along
various MFN routes for a period of 20 years with two ten-year renewals. This
agreement provides this NextLink affiliate with the exclusive rights of use to
certain fiber strands on intra-city routes in Metropolitan Philadelphia and
Washington, D.C., an inter-city link between New York City and Washington, D.C.
and additional routes in Metropolitan New York/New Jersey. Pursuant to the
agreement, the Company is to receive $92.0 million in payments from the
affiliate of NextLink, with $11.75 million paid upfront and $80.25 million to be
placed in escrow and released to MFN periodically as delivery of the fibers and
innerducts are completed during 1998 and 1999 in accordance with the agreement.
 
    CORPORATE/GOVERNMENT CUSTOMERS.  The Company expects that its corporate and
government customers, including members of the international financial and
commercial community, will primarily be entities with multiple locations and
high volume communications requirements. The Company expects to provide these
customers with dedicated point-to-point communications that have the capacity to
carry a wide range of communications services (e.g., high speed intranet
access). The Company offers its high-bandwidth
 
                                       9
<PAGE>
services to such customers at prices that are lower than those currently offered
by regulated CLECs and ILECs. However, the Company's customers currently provide
their own transmission or switching equipment.
 
    The Company believes it can effectively compete for corporate and government
customers based upon price, non-metered usage, reliability and solutions
tailored to the customers' needs. In addition, the Company's NY Network
utilizes, and the Intra-City Networks will permit use of, SONET technology and
offer reliability which the Company believes is generally superior to that
provided by the ILECs. The Company currently has dark fiber infrastructure
leasing arrangements with a variety of financial services firms, including
investment and commercial banks, securities and accounting firms and a financial
exchange, although installation of the dark fiber to be leased pursuant to
certain of the contracts has not yet been completed by the Company.
 
COMPETITION
 
    Fiber optic systems are currently under construction both locally and
nationally. In New York City, for example, seven franchisees have been granted
the right to install and operate a telecommunications network within the city.
Development of fiber optic networks is also continuing on a national scale; for
example, one provider of fiber is currently in the midst of constructing a
cross-continental long distance fiber optic network from Los Angeles to New York
and another, Qwest Communications International, is constructing a fiber-based
national backbone network which will connect more than 125 metropolitan areas
and span approximately 16,285 miles. Other companies have also recently
announced their intention to build national fiber-based networks.
 
    The construction of these networks enables their owners to lease access to
their networks to other communications carriers or large corporate or government
customers seeking high bandwidth capacity, without these customers having to
incur costly expenditures associated with building networks of their own.
Alternatively, some network owners may choose to use their infrastructure to
provide switched voice and data services, competing directly with ILECs and
IXCs. Currently, MFN does not provide such services or plan to provide such
services.
 
    In New York City and the cities where MFN plans to deploy fiber optic
communications networks, the Company faces significant competition from the
ILECs, which currently dominate their local communications markets. The Company
also faces competition from CLECs and other potential competitors in New York
City and will face competition in the cities in which the Company plans to build
its networks. Many of the Company's competitors have financial, management and
other resources substantially greater than those of the Company, as well as
other competitive advantages over the Company, including established reputations
in the communications market.
 
    Various communications carriers already own fiber optic cables as part of
their communications networks. Accordingly, each of these carriers could, and
some do, compete directly with the Company in the market for leasing fiber
capacity. In addition, although CLECs generally provide a wider array of
services to their customers than the Company presently provides to its
customers, CLECs nevertheless represent an alternative means by which a
potential customer of the Company could obtain direct access to an IXC POP or
other site of the customer's choosing. Thus, CLECs could compete with the
Company.
 
    Some communications carriers and local cable companies have extensive
networks in place that could be upgraded to fiber optic cable, as well as
numerous personnel and substantial resources to undertake the requisite
construction to so equip their networks. To the extent that communications
carriers and local cable companies decide to equip their networks with fiber
optic cable, they are potential direct competitors of the Company provided that
these competitors are willing to offer this capacity to all of their customers.
 
    The Company believes that as competition in the local exchange market
develops, a fundamental division between the needs of corporate, governmental
and institutional end users and residential end
 
                                       10
<PAGE>
users will drive the creation of differentiated communications services and
service providers. The Company believes that the CLECs, IXCs, ISPs, wireless
carriers and corporate and government customers on which it focuses will have
distinct requirements, including maximum reliability, consistent high quality
transmissions, capacity for high-speed data transmissions, diverse routing and
responsive customer service. The Company believes that it will be able to
satisfy the needs of such customers.
 
REGULATION
 
    On February 8, 1996, the Telecommunications Act of 1996 (the "1996 Act"),
the most comprehensive reform of the nation's telecommunications laws since the
Communications Act, was enacted. The 1996 Act has resulted in substantial
changes in the marketplace for communications services that should be largely
favorable to the Company.
 
    FEDERAL
 
    The 1996 Act imposes a number of access and interconnection requirements on
all local exchange providers, including CLECs, with additional requirements
imposed on ILECs. The 1996 Act provides a detailed list of items which are
subject to these interconnection requirements, as well as a detailed set of
duties for all affected carriers. All LECs, including CLECs, have a duty to (i)
not unreasonably limit the resale of their services, (ii) provide number
portability if technically feasible, (iii) provide dialing parity to competing
providers, and nondiscriminatory access to telephone numbers, directory
assistance, operator services and directory listings, (iv) provide access to
poles, ducts, conduits and rights-of-way and (v) establish reciprocal
compensation arrangements for the transport and termination of
telecommunications. In addition to those general duties of all LECs, ILECs have
duties to (i) interconnect at any technically feasible point and provide service
equal in quality to that provided to their customers or the ILEC itself, (ii)
provide unbundled access to network elements at any technically feasible point
at just, reasonable and nondiscriminatory rates, terms and conditions, (iii)
offer retail services at wholesale prices for the use of telecommunication
carriers, (iv) provide reasonable public notice of changes in the network or the
information necessary to use the network or which affect interoperability and
(v) provide for physical collocation. "Physical collocation" is an offering by
an ILEC that enables another telecommunications carrier to enter the ILEC's
premises to install, maintain and repair its own equipment that is necessary for
interconnection or access to the ILEC's network elements. An ILEC must allocate
reasonable amounts of space to carriers on a first-come first-served basis. If
space limitations or practical or technical reasons prohibit physical
collocation, an ILEC must offer "virtual collocation," by which the other
carrier may specify ILEC equipment to be dedicated to its use and electronically
monitor and control communications terminating in such equipment.
 
    The FCC adopted pricing and other guidelines to implement the
interconnection provisions of the 1996 Act, but the 8th Circuit Court of Appeals
recently vacated most of the FCC's guidelines. The 8th Circuit's decision is
expected to be reviewed by the Supreme Court in its 1998-99 term. The
responsibility for setting pricing and other guidelines with respect to
interconnection has thus been left up to the individual state public service
commissions. It is expected that varying pricing and guidelines will emerge from
state to state, and some of these guidelines may eventually have an indirect
adverse effect on the Company's business.
 
    Federal telecommunications law directly shapes the market in which the
Company competes. Consequently, undesirable regulatory changes could adversely
affect the Company's business, financial conditions and results of operations.
 
    Federal telecommunications law imposes special legal requirements on "common
carriers" who engage in "interstate or foreign communication by wire or radio."
The Company believes that the leasing of dark fiber facilities does not
constitute engaging in "communication by wire or radio" and therefore is not
subject to these legal requirements. In any event, the Company does not intend
to offer its dark fiber
 
                                       11
<PAGE>
facilities as a common carrier. Common carriers are those who offer services
directly to the public, or to all potential users on an indiscriminate basis
subject to standardized rates, terms or conditions. The Company does not intend
to offer its dark fiber services in this manner, but instead intends to enter
into individualized negotiations on a selective basis with prospective lessees
of its dark fiber facilities to determine whether and on what terms to serve
each potential lessee. The Company therefore does not believe that its dark
fiber offerings are subject to the common carrier jurisdiction of the FCC or to
the common carrier provisions of the Communications Act.
 
    Federal telecommunications law also imposes special legal requirements on
"telecommunications carriers." The law essentially defines "telecommunications
carriers" as those offering certain telecommunication services "directly to the
public" or to all potential users. The Company therefore believes that a company
has to be a common carrier in order to be considered a telecommunications
carrier. For the reasons stated above, the Company believes that it is neither a
common carrier nor a telecommunications carrier with respect to its dark fiber
service. Nevertheless, the law is not entirely clear as to, and the FCC has not
definitively addressed whether, the term "telecommunications carriers" is meant
to encompass only common carriers, and therefore whether a provider of dark
fiber facilities on an individualized basis, like the Company, is a
"telecommunications carrier." The FCC has been petitioned by certain railroad,
power and telecommunications associations, none of which are affiliated with the
Company, to clarify the status of dark fiber providers in this respect, and if
the agency decides that such companies are telecommunications carriers, then the
Company would be subject to certain additional regulatory requirements. These
requirements may have a material adverse effect on the Company.
 
    If the Company's offering of dark fiber facilities were deemed to constitute
a "telecommunications service," then its revenues from such leases to end users
(but not to other telecommunication carriers) would become subject to assessment
for the FCC's Universal Service Fund, a fund that was established by the FCC
pursuant to the Telecom Act to assist in ensuring the universal availability of
basic telecommunications services at affordable prices. Such assessments could
create a liability equal to a percentage of these gross revenues. The Company
anticipates that the rate of assessment will be approximately 4.5% of gross
interstate end-user revenues for the year 1998, and may be higher in subsequent
years). The Company also may be liable for assessments by state commissions for
state universal service programs.
 
    With respect to its offering of telecommunications transmission services,
however, the Company will likely operate as a common carrier and therefore will
be subject to the regulatory requirements applicable to common carriers and to
telecommunications carriers. For example, the Company will be required, with
respect to its transmission services, to (1) provide such services
indiscriminately upon any reasonable request; (2) charge rates and adopt
practices, classifications and regulations that are just and reasonable; and (3)
avoid unreasonable discrimination in charges, practices, regulations, facilities
and services. The Company may also be required to file tariffs setting forth the
rates for its services. Under current FCC policies, these regulatory
requirements should not impose any substantial burdens on the Company. The FCC
has recently determined, for example, that providers of "access" services
(intracity transmission services used to originate and/or terminate interstate
and foreign communications) need not file tariffs and may offer such services to
customers on a private, contractual basis. Although the FCC's policies may be
subject to change in the future due to regulatory, judicial, or legislative
actions, and such changes could have a material adverse effect on the Company,
the Company does not believe that regulation of its services at the federal
level will have any detrimental effect on its competitiveness. The Company's
revenues from transmission services will be subject to FCC Universal Service
Fund assessments as described above, to the extent that these services are
purchased by end users; since the revenues of the Company's competitors will be
subject to comparable assessments; however, this should not reduce the Company's
competitiveness.
 
    ILECs, CLECs and IXCs are subject to various federal telecommunications
laws. Accordingly, federal telecommunications law may affect the Company's
business by virtue of the inter-relationships that exist among the Company and
many of these regulated telecommunications entities. For example, the FCC
 
                                       12
<PAGE>
recently issued an order requiring, among other things, that common line access
fees charged to IXCs, which previously amounted to more than what was necessary
to recover the costs of providing access, shift from being usage driven to a
fixed flat cost-based structure. While it is not possible to predict the precise
effect the access charge changes will have on the Company's business or
financial condition, the reforms will reduce access charges paid by IXCs, likely
eliminating one of the principal disincentives for use of ILEC facilities by
IXCs, which could have a material adverse effect on the use of the Company's
fiber optic telecommunications networks by IXCs.
 
    The FCC has responsibility under the 1996 Act's interconnection provisions
to determine what elements of an ILEC's network must be provided to competitors
on an unbundled basis. The FCC has decided not to declare dark fiber an
unbundled network element under these provisions. This decision is currently
subject to petitions for reconsideration before the FCC. An FCC decision to
alter this decision on reconsideration could decrease the demand for dark fiber
provided by the Company. In addition, the FCC has announced that state
commissions may decide to add network elements to the FCC's list of elements
that are required to be unbundled by all carriers throughout the country.
 
    STATE
 
    The 1996 Act prohibits state and local governments from enforcing any law,
rule or legal requirement that prohibits or has the effect of prohibiting any
person from providing any interstate or intrastate telecommunications service.
Notwithstanding the prohibition contained in the 1996 Act, states regulate
telecommunications services, including through certification of providers of
intrastate services, regulation of intrastate rates and service offerings, and
other regulations. Nonetheless, this provision of the 1996 Act should enable the
Company and customers of the Company to provide telecommunications services in
states that previously prohibited competitive entry.
 
    States retain jurisdiction under the 1996 Act to adopt regulations necessary
to preserve universal service, protect public safety and welfare, ensure the
continued quality of communications services and safeguard the rights of
consumers. States are also responsible for mediating and arbitrating CLEC-ILEC
interconnection arrangements if voluntary agreements are not reached.
Accordingly, the degree of state involvement in local telecommunications
services may be substantial.
 
    In arbitrating interconnection agreements under the 1996 Act between ILECs
and their potential competitors, some state commissions have considered whether
dark fiber should be considered an unbundled network element. For example, the
New York Public Service Commission determined that it would not require Bell
Atlantic to provide dark fiber as an unbundled network element. State
commissions, including those in Florida, Maryland, North Carolina, and Virginia,
also have either refused to require the ILECs to offer dark fiber to
competitors, or have stated that the issue would be addressed at a later time.
On the other hand, state commissions in Illinois, Massachusetts, Arizona,
Georgia, Minnesota, Ohio, Oregon and Tennessee have found dark fiber to be a
network element and required the ILECs to offer it on an unbundled basis to
CLECs. There can be no assurance that these requirements, and the associated
pricing methodologies, where applicable, will not reduce the demand for dark
fiber provided by the Company.
 
    Each state (and the District of Columbia, which is treated as a state for
the purpose of regulation of telecommunications services) has its own statutory
scheme for regulating providers of certain telecommunications-related services
as "common carriers," as "public utilities," or under similar rubrics. The
Company believes that the offering of dark fiber facilities is not subject to
this type of regulation in the states in which the Company currently intends to
operate. However, the Company's offering of transmission services (as distinct
from dark fiber capacity) likely will be subject to regulation in each of these
jurisdictions to the extent that these services are offered for intra-state use.
Even though many of the Company's facilities will be physically intra-state, the
Company anticipates that most customers will use its
 
                                       13
<PAGE>
facilities and services for the purpose of originating and/or terminating
inter-state and foreign communications. Under current FCC policies, any
dedicated transmission service or facility that is used more than 10% of the
time for the purpose of inter-state or foreign communication is subject to FCC
jurisdiction to the exclusion of any state regulation.
 
    Regulation of the telecommunications industry is changing rapidly, and the
regulatory environment varies substantially from state to state. At present, the
Company does not anticipate that the regulatory requirements to which it will be
subject in the states in which the Company currently intends to operate will
have any material adverse effect on its operations, although the Company will
incur certain costs to comply with regulatory requirements such as the filing of
tariffs, submission of periodic financial and operational reports to regulators,
and payment of regulatory fees and assessments. In some jurisdictions, the
Company's pricing flexibility for intra-state services may be limited because of
regulation, although the Company's direct competitors will be subject to similar
restrictions. However, there can be no assurance that future regulatory,
judicial, or legislative action will not have a material adverse effect on the
Company.
 
    In response to the 1996 Act, Bell Atlantic "unbundled" its local loop in
October 1996. As a result, carriers such as the Company will be permitted to
access Bell Atlantic's existing wiring infrastructure in buildings on an
economical basis, which the Company believes enhances the strategic value of the
NY Network to potential customers. By virtue of the unbundling, Bell Atlantic
must make a significant portion of its in-house apartment wiring available for
$2 per month per apartment. The availability of an unbundled local loop will
enable new carriers to enter the residential voice market on a competitive basis
with Bell Atlantic.
 
    LOCAL
 
    In addition to federal and state laws, local governments exercise legal
authority that may impact the Company's business. For example, local
governments, such as the City of New York, typically retain the ability to
license public rights-of-way, subject to the limitation that local governments
may not prohibit persons from providing telecommunications services. Local
authorities affect the timing and costs associated with the Company's use of
public rights-of-way. These regulations may have an adverse effect on the
Company's business.
 
    INTERNATIONAL
 
    Various regulatory requirements and limitations also will influence the
Company's business as it attempts to enter international markets.
 
    Although the Company has not fully determined its international business
strategy, the Company has negotiated an agreement with a foreign firm that
contemplates jointly acquiring and selling international, facilities-based
telecommunications capacity between the U.S. and the United Kingdom. Depending
on the Company's specific business plan in this arrangement, it is possible that
the Company will become a U.S. international common carrier subject to U.S.
regulation under Title II of the Communications Act. Under current FCC rules,
international carriers that do not exercise market power and that are not
affiliated with dominant foreign carriers are subject to relatively relaxed U.S.
regulation as nondominant international carriers. As a common carrier, the
Company would be subject to among other policies, the common carrier obligations
of nondiscrimination. In addition, FCC rules prohibit U.S. carriers from
bargaining for special concessions from certain foreign partners. The Company
would also be required, under Sections 214 and 203 of the Communications Act,
respectively, to obtain authority and file an international service tariff
containing rates, terms and conditions prior to initiating service. As a
nondominant carrier, the Company would be eligible to seek "global" authority to
operate as facilities-based and/or resale carrier in an application subject to
the FCC's streamlined processing rules. International carriers are also subject
to certain annual fees and filing requirements, including the requirement to
file contracts with other carriers including foreign carrier agreements, and
reports setting forth international circuit, traffic and revenue
 
                                       14
<PAGE>
data. Failure to obtain an appropriate U.S. license for international service or
the revocation of a license could have a material adverse effect on the future
operations of the Company.
 
    If the Company operates as an international common carrier, it will also be
required to comply with FCC's International Settlements Policy ("INSP") which
defines the permissible boundaries for U.S. carriers and their foreign
correspondents to settle the cost of terminating each other's traffic over their
respective networks. The INSP is designed to eliminate a foreign carrier's
opportunity to discriminate among different U.S. carriers by bargaining for
accounting rates or other terms that benefit the foreign carrier but is
inconsistent with the U.S. public interest. The INSP generally provides that
U.S. carriers may only enter into foreign carrier agreements for the exchange of
traffic that contain the same accounting rate and settlement rate (typically
one-half of the accounting rate) offered to all other U.S. carriers. The INSP
also requires U.S. carriers to adhere to the principle of proportionate return
so that competing U.S. carriers have comparable opportunities to receive the
return traffic that reduces the marginal cost of providing international
service.
 
    If the Company provides public switched services over international private
lines, it would be subject to FCC rules governing such activity rather than to
the INSP. These rules limit the Company from providing switched services over
international private lines between the United States and certain countries and
impose certain conditions on carriers engaging in such activity.
 
    The FCC continues to refine its international service rules to promote
competition, reflect and encourage liberalization in foreign countries, and
reduce accounting rates toward cost. Among other things, the FCC has recognized
the advent of competition in the U.K. market by designating the U.K. as a
country that offers U.S. carriers effective competitive opportunities. The FCC
has also amended its rules to reflect the U.S. participation in the WTO
Agreement on Basic Telecommunications Services in which 72 countries have agreed
to eliminate barriers to competition in their markets for basic
telecommunications services. For example, the FCC has decided to permit U.S.
carriers to enter into "flexible" termination arrangements with carriers in WTO
countries, unless such arrangements would not promote competition. By taking
these actions, the FCC has relaxed or eliminated regulatory limitations on many
U.S. carrier services between U.S. and the U.K. (as well as between the U.S. and
other members of the WTO). In addition, the FCC has established reduced
"benchmark" rates for the amounts U.S. carriers will be allowed to pay to
foreign carriers for terminating U.S.-originated traffic. As of January 1, 1999,
U.S. carriers may ask the FCC to require that U.S. carriers pay foreign carriers
in "high income" countries such as the United Kingdom no more than $.15 per
minute to terminate such calls. Different rates would apply in different
countries depending on the countries' wealth.
 
    Regulation of the international telecommunications industry is changing
rapidly. The Company is unable to predict how the FCC will resolve the various
pending international policy issues and the effect of such resolutions on the
Company.
 
    The Company's international services would also be subject to regulation in
the United Kingdom. U.K. regulation, as well as policies and regulations on the
European Union level, would impose separate licensing, service and other
conditions on the Company's international service operations, and these
requirements may have a material adverse impact on the Company.
 
EMPLOYEES
 
    As of March 10, 1998, the Company employed 48 people. The Company's
employees are not represented by any labor union. The Company considers its
relationship with employees to be good.
 
ITEM 2. PROPERTIES
 
    The NY Network and its component assets are the principal properties
currently owned by the Company. The Company owns substantially all of the
communications equipment required for its business.
 
                                       15

The Company's installed fiber optic cable is laid under the various
rights-of-way held by the Company. See Item 1 "Business--Build-out of
Networks--Rights-of-Way." Other fixed assets are located at various leased
locations in geographic areas served by the Company.
 
    The Company's executive and administrative offices are located at its
principal office at One North Lexington Avenue, White Plains, New York. MFN
leases this space (currently 15,061 square feet, expandable to 21,336 square
feet) under an agreement that expires in March 2003. The Company's sales offices
are located at 110 East 42nd Street, New York, N.Y. under an agreement that
expires in June 1998. The Company leases additional space at 60 Hudson Street,
New York, New York, from Hudson Telegraph Associates.
 
ITEM 3. LEGAL PROCEEDINGS
 
    On or about April 18, 1997, Howard Katz, Realprop Capital Corp. and Evelyn
Katz commenced an action against the Company, Stephen A. Garofalo, Peter Sahagen
and Peter Silverman in the United States District Court for the Southern
District of New York captioned KATZ, ET AL. v. NATIONAL FIBER NETWORK, INC., ET
AL., No. 97 Civ. 2764 (JGK) (the "Katz Litigation"). (National Fiber Network,
Inc. is the former name of the Company). On May 28, 1997, the plaintiffs filed
an amended complaint and on September 15, 1997, the plaintiffs filed a second
amended complaint, which, among other things, added Metromedia and Silverman,
Collura, Chernis & Balzano, P.C. as defendants. The second amended complaint
alleges causes of action for, among other things, common law fraud, violations
of Section 10(b) of the Securities Exchange Act of 1934 and Rule 10b-5
promulgated thereunder, breach of fiduciary duty and negligent
misrepresentation, for alleged misrepresentations and omissions made in
connection with the repurchase of the Katz Securities (as defined below under
"Certain Relationships and Related Transactions"). The second amended complaint
also contains allegations of corporate waste against the Company and Mr.
Garofalo. Plaintiffs seek, among other things, compensatory damages of not less
than $12 million, punitive damages in the amount of $100 million and, in the
alternative, rescission of the purchase by the Company of 264,631 shares of
Class A Common Stock and 207,883 warrants to acquire shares of Class A Common
Stock. On October 31, 1997, all defendants moved to dismiss the second amended
complaint. The motions were fully briefed as of December 12, 1997. The Company
intends to vigorously defend itself against these allegations based on its
belief that MFN acted appropriately in connection with the matters at issue in
this litigation. No assurance can be made though, that the Company will not
determine that the advantages of entering into a settlement outweigh the risks
and expense of protracted litigation or that ultimately the Company will be
successful in its defense of the allegations. If the Company is unsuccessful in
its defense of the allegations, an award of the magnitude being sought by the
plaintiffs in the Katz Litigation would have a material adverse effect on the 3
Company's financial condition or results of operations.
 
    On or about October 20, 1997, Vento & Company of New York, LLC ("VCNY")
commenced an action against the Company, Stephen A. Garofalo, Peter Silverman,
the law firm of Silverman, Collura, Chernis & Balzano, P.C., Peter Sahagen,
Sahagen Consulting Group of Florida (collectively, the "Sahagen Defendants") and
Robert Kramer, Birdie Capital Corp., Lawrence Black, Sterling Capital LLC,
Penrush Limited, Needham Capital Group, Arthur Asch, Michael Asch and Ronald
Kuzon (the "Kramer Defendants") in the United States District Court for the
Southern District of New York (No. 97 CIV 7751) (the "VCNY Litigation"). The
complaint alleges causes of action for, among other things, violation of Section
10(b) of the Securities Exchange Act of 1934 and Rule 10b-5 promulgated
thereunder, fraud and fraudulent concealment, breach of fiduciary duty and
negligent misrepresentation and omission made in connection with the sale by
VCNY of 1,368,900 shares of Class A Common Stock to Peter Sahagen and the Kramer
Defendants on January 13, 1997 (the "VCNY Sale"). The complaint also alleges a
cause of action for declaratory judgment asserting that certain "piggyback"
registration rights are applicable to shares of the Company's Class A Common
Stock which VCNY owns (or which may be rescinded to VCNY pursuant to its
requested remedies). The complaint further requests a declaratory judgment that
a stockholders
 
                                       16
<PAGE>
agreement between the Company, Stephen Garofalo and VCNY be declared operative,
which agreement indirectly required VCNY, through designated directors, to
approve significant transactions, and, accordingly, the Metromedia Loan and the
Metromedia Investment should be rescinded and Mr. Vento should be reappointed as
Chief Executive Officer of the Company. The Company believes, among other
things, that the stockholders agreement to which Mr. Vento was a party had
terminated and as a result Mr. Vento had no such rights to approve the
Metromedia Investment or the Metromedia Loan or to remain as Chief Executive
Officer of the Company. Plaintiff seeks, among other things, (i) rescission of
the VCNY Sale, or alternatively, damages in an amount not presently
ascertainable, but believed to be in the excess of $36 million, together with
interest thereon, (ii) punitive damages in the amount of $50 million, and (iii)
the declaratory judgments discussed above. The Company intends to vigorously
defend itself against these allegations based on its belief that MFN acted
appropriately in connection with the matters at issue in this litigation. No
assurance can be made, though, that the Company will not determine that the
advantages of entering into a settlement outweigh the risk and expense of
protracted litigation or that ultimately the Company will be successful in its
defense of the allegations. If the Company is unsuccessful in its defense of the
allegations, an award of the magnitude being sought by the plaintiffs in the
VCNY Litigation would have a material adverse effect on the Company's financial
condition or results of operations.
 
    In addition, the Company is subject to various claims and proceedings in the
ordinary course of business. Based on information currently available, the
Company believes that none of such current claims, or proceedings, individually
or in the aggregate, including the Katz Litigation and the VCNY Litigation, will
have a material adverse effect on the Company's financial condition or results
of operations, although there can be no assurances in this regard.

    a. Since October 28, 1997, the Class A Common Stock has been listed and
traded on the Nasdaq National Market (the "Nasdaq") under the symbol "MFNX." The
following table shows the range of reported high and low closing prices per
share of Class A Common Stock.

    As of March 27, 1998, there were approximately 104 record holders of Class A
Common Stock and two record holders of Class B Common Stock. The closing price
for the Class A Common Stock on such date was $37.00 per share as reported on
the Nasdaq National Market.
 
    On October 28, 1997, in connection with the Offering, the Company approved
of two share exchanges pursuant to which 9,564,940 shares of the old common
stock, par value $.01 per share, were exchanged for the same number of shares of
Class A Common Stock and a total of 8,403.25 shares of the Series B Convertible
Preferred Stock, par value $.01 per share of the Company were exchanged for
4,260,486 shares of the Company's Class B Common Stock. Immediately thereafter,
two shareholders converted an aggregate of 39,327 shares of Class B Common Stock
into an equivalent number of shares of Class A Common Stock. These exchanges
were exempt from registration under the Securities Act of 1933, as amended, by
virtue of Section 3(a)(9) thereof.
 
    DIVIDENDS.  The Company has never declared or paid any cash dividends on its
Class A Common Stock and does not expect to do so in the foreseeable future. The
Company anticipates that all future earnings, if any, generated from operations
will be retained to finance the expansion and continued development of its
business. Any future determination with respect to the payment of dividends will
be within the sole discretion of the Company's Board and will depend upon, among
other things, the Company's earnings, capital requirements, the terms of then
existing indebtedness, applicable requirements of the Delaware General
Corporation Law, general economic conditions and such other factors considered
relevant by the Company's Board. See Item 7 "Management's Discussion and
Analysis of Financial Condition and Results of Operations."
 
    b. USE OF PROCEEDS. On November 3, 1997, the Company successfully completed
the Offering of 9,108,000 shares of Class A Common Stock. The principal
underwriters in connection with the Offering included Salomon Brothers Inc.,
Donaldson, Lufkin & Jenrette Securities Corporation and Deutsche Morgan Grenfell
Inc. The aggregate offering price was $145,728,000 and the aggregate
underwriting discount was $10,200,960. The Offering generated net proceeds to
the Company of approximately $135.5 million, before deducting other offering
expenses. The shares sold through the Offering were registered pursuant to a
registration statement on Form S-1 (Registration No. 333-33653) which was
declared effective on October 28, 1997. The Offering terminated on November 3,
1997 after all 9,108,000 shares of Class A Common Stock were sold.
 
    The following table sets forth all expenses paid by the Company, other than
underwriting discounts and commissions, in connection with the issuance and
distribution of the shares sold through the Offering. None of the amounts shown
were paid directly or indirectly to any director, officer, general partner of

    Net proceeds to the Company after deducting offering expenses and
underwriting discounts totaled $133.9 million. Such net proceeds will be used
primarily for capital expenditures associated with the build-out of the MFN

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
  OF OPERATIONS
 
    The following discussion and analysis relates to the financial condition and
results of operations of the Company for the three years ended December 31,
1997. This information should be read in conjunction with the "Item 6. Selected
Financial Data" and the Company's consolidated Financial Statements and related
notes thereto appearing elsewhere in this document.
 
STATEMENT ON FORWARD-LOOKING INFORMATION
 
    Certain information included herein contains statements that constitute
"forward-looking statements." For a related discussion, see "Part I. Special
Note Regarding Forward-Looking Statements."
 
GENERAL
 
    The Company is a facilities-based provider of technologically advanced,
high-bandwidth fiber optic communications infrastructure to carrier and
corporate/government customers, primarily in the form of leased fiber optic
cables and circuits. The Company currently operates a 107 route mile fiber optic
network within the New York/New Jersey metropolitan area which consists of in
excess of 27,000 fiber miles. The company plans to expand its existing network
within the next two years to encompass approximately 229,000 fiber miles, in
excess of 650 route miles, concentrated in the northeastern United States. The
planned build-out will include intra-city fiber optic networks in Washington,
D.C., Chicago and Philadelphia, as well as an inter-city network between New
York and Washington, D.C. In the fourth quarter of 1997, the Company entered
into the MFN/Racal Joint Venture to provide broadband transatlantic
communication services to their respective customers. The Company anticipates
that initial service, which will include fiber optic international leased line,
ranging in capacity from 2Mb to 45Mb, will be available by the second quarter of
1998. See "Item 1. Business."
 
RESULTS OF OPERATIONS
 
YEAR ENDED DECEMBER 31, 1997 COMPARED TO YEAR ENDED DECEMBER 31, 1996:
 
    Revenues for 1997 were $2,524,311, a 969% increase as compared to 1996
revenues of $236,082. The revenue increase was generated by one time revenues
associated with commencement of services to customers as well as increased
recurring lease revenues which reflects the growth in the number of customers.
 
    Cost of sales for 1997 were $3,572,005, an increase of 411% versus the
$698,793 which was recorded as cost of sales in 1996. The increase in cost of
sales was associated with the increased revenues. Cost of sales as a percentage
of revenues improved to 142% in 1997 from 296% in 1996. The improvement in cost
of sales as a percentage of revenues reflects the increases in revenue
outdistancing the increases in cost, as the components of cost were mostly of a
fixed nature.
 
    Selling, general and administrative expenses increased to $6,303,041 in 1997
from $2,070,345 in 1996, a 204% increase. This increase resulted primarily from
increased legal expenses as a result of the increased business activities within
the Company and increased staffing to accommodate the Company's anticipated
growth.
 
    Consulting and employment incentives expense of $19,218,591 was recorded in
1997 versus $3,652,101 in 1996. The 1997 expense represents the value of stock
options issued to key employees, officers, directors and consultants in order to
attract or retain their services. The amount recorded in 1996 reflects the
expense associated with issuance of stock and warrants to consultants in
consideration for services rendered.
 
                                       21
<PAGE>
    Depreciation and amortization expense was $757,133 in 1997 as compared to
$612,530 in 1996. The increase in depreciation and amortization expense resulted
from increased investment in the Company's fiber optic network.
 
    Interest income of $1,808,007 was recorded in 1997 versus no interest income
during 1996. The interest income in 1997 arose from the investment of the
Company's excess cash during the year. In 1996, the Company had no excess cash
to invest and, accordingly, earned no interest income. See "Item 5. Market for
Registrant's Common Equity and Related Stockholder Matters--Use of Proceeds."
 
    Interest expense (including financing costs) decreased in 1997 to $740,786
from $3,561,010 in 1996. The decrease in interest expense reflects the repayment
of all of the Company's debt during the year with the proceeds of the Metromedia
Investment, as well as lower financing costs.
 
    A net loss of $26,259,238 was recorded in 1997 versus a net loss of
$10,358,697 in 1996. The increase in the net loss was primarily attributable to
costs associated with organizing to meet the growth objectives of the Company.
In particular, such costs include the consulting and employment incentive,
described above, to attract and retain key employees, officers and directors, as
well as increased overhead to meet the Company's growth objectives.
 
YEAR ENDED DECEMBER 31, 1996 COMPARED TO YEAR ENDED DECEMBER 31, 1995:
 
    During the year ended December 31, 1995, the Company was in its early
development stage and did not generate its first revenues until the last three
months of 1995 when customers began using the Company's facilities.
 
    Total revenues increased to $236,082 for the year ended December 31, 1996
from $56,149 for the year ended December 31, 1995, representing an increase of
$179,933. The increase in revenue was due primarily to an increase in the number
of customers.
 
    Cost of sales was $698,793 for the year ended December 31, 1996. There were
no cost of sales recorded for the year ended December 31, 1995. The increase was
primarily attributable to the inclusion of franchise fees and easement costs in
cost of sales for 1996. In prior years such fees were classified as selling,
general and administrative expense.
 
    Selling, general and administrative expenses decreased to $2,070,345 for the
year ended December 31, 1996 from $3,886,568 for the year ended December 31,
1995, representing a decrease of $1,816,223.
 
    Consulting and employment incentives were $3,652,101 for the year ended
December 31, 1996 versus none in 1995, reflecting the Company's issuance of
equity instruments for consulting services.
 
    Depreciation and amortization increased to $612,530 for the year ended
December 31, 1996 from $161,576 for the year ended December 31, 1995,
representing an increase of $450,954. Certain components of depreciation and
amortization are recognized by the Company upon commencement of service to
customers, which did not occur until late 1995. As a result, depreciation and
amortization in 1996 was larger than it was in 1995 due to the inclusion of a
full year of depreciation and amortization for such customers.
 
    Interest Expense (including financing costs) increased to $3,561,010 for the
year ended December 31, 1996 from $327,106 for the year ended December 31, 1995,
representing an increase of $3,233,904. This increase was a result of additional
debt incurred in 1996 to finance construction of the NY Network and to fund the
operations of the Company.
 
    Net Loss increased to $10,358,697 for the year ended December 31, 1996 from
$4,319,101 for the year ended December 31, 1995, representing an increase of
$6,039,596. The increase in net loss is attributable to the factors discussed
above.
 
                                       22

LIQUIDITY AND CAPITAL RESOURCES
 
    On November 3, 1997, the Company generated net proceeds of $133.9 million in
the Offering of 9,108,000 shares of its Class A Common Stock, after deducting
the underwriters' commission and expenses relating to the Offering.
 
    During 1997, the Company utilized approximately $7.7 million for operating
activities primarily to prepay a long term, non-exclusive right-of-way in order
to build-out a portion of its network and also to meet the growth objectives of
the Company. A portion of the operating activities were funded by advance
payments received from customers. In addition, the Company utilized
approximately $9.8 million in 1997 for investing activities, primarily to
build-out the Company's network. In 1997, approximately $155.9 million of cash
flows were provided by financing activities reflecting the net proceeds of the
Offering, as discussed above, and by the equity investment in MFN of $32.5
million made by Metromedia Company and certain of its affiliates on April 30,
1997, a portion of which was utilized to repay all the outstanding debt of the
Company and purchase all of the Company's Series A preferred stock outstanding
at April 30, 1997.
 
    Cash used in operating activities during 1996 was approximately $2.75
million as compared to approximately $1.3 million in 1995. Cash was utilized in
both years to support the operations through the Company's startup phase. Cash
flows used in investing activities were approximately $1.1 million in 1996 and
approximately $4.2 million in 1995. The investing activities cash outflows in
both years were primarily used for the building of the Company's New York City
Network. Financing activities provided cash flows of approximately $4.3 million
in 1996 and approximately $5.2 million in 1995 with the issuance of equity in
1996 and the issuance of debt in both 1996 and 1995. The cash flows from
financing activities in both 1996 and 1995 were utilized to fund the Company's
operating and investing activities.
 
    The Company anticipates that it will continue to incur net operating losses
as it expands the NY Network, constructs additional networks and markets its
services to an expanding customer base. The Company anticipates spending
approximately $124.0 million through 1998 on the build-out of its fiber optic
network. Cash provided by operations will not be sufficient to fund the
expansion and development of networks as currently planned and as a result the
Company intends to use cash on hand and the net proceeds of the Offering to fund
this expansion and development; Management believes that the cash on hand as of
December 31, 1997 along with cash generated in 1998 (including advance customer
payments), will be sufficient to fund the Company's planned build-out of its
fiber optic network and its other working capital needs through the year ended
December 31, 1998. The Company may also consider from time to time private or
public sales of additional equity or debt securities of the Company and bank
financings, depending upon market conditions, in order to finance the continued
build-out of its network. There can be no assurance that the Company will be
able to successfully consummate any such financing at all, or on acceptable
terms. Accordingly, the Company expects to continue experiencing net operating
losses and negative cash flows for the foreseeable future.
 
    The Company has completed an assessment of its exposure to the "year 2000"
computer problem. Based on this assessment, the Company believes that no
critical software systems will be impacted by this situation. Systems currently
in use are already "year 2000" compliant. Although the Company believes that it
is taking appropriate precautions against disruption of its systems due to the
"year 2000" problem, there can be no assurance that the Company's suppliers and
customers will not be adversely affected by the "year 2000" problem.
Nonetheless, the Company believes that the "year 2000" issue will not have a
material impact on MFN's business operations or financial condition.
 
ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
 
    The Company will be required to provide both quantitative and qualitative
disclosures about market risk in its Annual Report on Form 10-K for the fiscal
year ending December 31, 1998.

These consolidated financial statements and schedule are the responsibility of
the Company's management. Our responsibility is to express an opinion on these

significant estimates made by management, as well as evaluating the overall
consolidated financial statement presentation. We believe that our audits
provide a reasonable basis for our opinion.
 
    In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the consolidated financial position of
Metromedia Fiber Network, Inc. and Subsidiaries as of December 31, 1997 and
1996, and the consolidated results of their operations and their cash flows for
the years then ended in conformity with generally accepted accounting

To the Board of Directors and Shareholders of
 
    Metromedia Fiber Network, Inc.
 
    We have audited the accompanying consolidated statements of operations,
stockholders' deficiency and cash flows for the year ended December 31, 1995 of
Metromedia Fiber Network, Inc. and Subsidiaries (the "Company"). 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 audit.
 
    We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audits to obtain
reasonable assurance about whether the consolidated financial statements are
free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the consolidated financial
statements. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
consolidated financial statement presentation. We believe that our audit
provides a reasonable basis for our opinion.
 
    In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the consolidated results of operations
and cash flows for the year ended December 31, 1995 of Metromedia Fiber Network,
Inc. and Subsidiary in conformity with generally accepted accounting principles.
 
    The accompanying consolidated financial statements have been prepared
assuming that the Company will continue as a going concern. As discussed in Note
1 to the consolidated financial statements, the Company's significant recurring
losses, operating history and significant working capital deficiency, including
significant amounts of past due payables, raise substantial doubt about the
Company's ability to continue as a going concern. Management's plans in regard
to these matters are also discussed in Note 1. The consolidated financial
statements do not include any adjustments relating to the recoverability and
classification of recorded asset amounts or the amounts and classification of
liabilities that might result from the outcome of this uncertainty.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
BUSINESS OPERATIONS AND LINE OF BUSINESS
 
    Metromedia Fiber Network, Inc. (formerly National Fiber Network, Inc.) and
its subsidiaries (the "Company") was granted a nonexclusive right from the City
of New York, effective December 20, 1993, to provide telecommunication services
and construct a fiber optic network for the purpose of providing these services.
In October 1995, the basic backbone of the Fiber Optic Cable Network in the City
of New York was completed and the Company began servicing its customers.
 
    The Company entered into a joint venture agreement with Racal
Telecommunications, Inc. ("Racal") on November 26, 1997. The joint venture will
enable the Company and Racal to provide broadband transatlantic communication
services, between New York and London, to their respective customers. Racal is
part of the Racal Electronics Group which is headquartered in the United
Kingdom.
 
    The accompanying consolidated financial statements have been prepared on a
going concern basis which contemplates the realization of assets and the
satisfaction of liabilities in the normal course of business. On April 30,1997
the Company sold 8,403.325 shares of Series B preferred shares in exchange for
$32,500,000 in cash. Prior thereto, the Company had working capital deficiencies
and stockholders' deficiencies. Further, substantially all of its trade payables
and certain current liabilities were past due. These factors, prior to the April
1997 sale of preferred stock, raised substantial doubt about the Company's
ability to continue as a going concern.
 
BASIS OF PRESENTATION
 
    The consolidated financial statements include the accounts of the Company
and it subsidiaries. All intercompany balances and transactions have been
eliminated in consolidation. The investment in the Racal joint venture in which
the Company owns 50% is accounted for by the equity method. Certain balances
have been restated to conform to the current period presentation.
 
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 at the
date of the financial statements and the reported amounts of revenues and
expenses during the reporting period. Actual results could differ from those
estimates.
 
CASH AND CASH EQUIVALENTS
 
    For purposes of the consolidated financial statements the Company considers
all highly liquid investments with an original maturity of three months or less
when purchased to be cash equivalents.
 
FIBER OPTIC TRANSMISSION NETWORK AND RELATED EQUIPMENT
 
    The fiber optic transmission network and related equipment are stated at
cost. Costs in connection with the installation and expansion of the network are
capitalized. Depreciation is computed using the straight-line method through the
life of either the franchise agreement or right of way for the related network.

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
PROPERTY AND EQUIPMENT
 
    Property and equipment are stated at cost. Depreciation is computed using
the straight-line method over the estimated useful lives of the assets.
 
FRANCHISE COSTS
 
    Amortization of franchise costs on the New York City Network began upon
commencement of service to customers and is computed on the straight-line method
through December 20, 2008 (159 months), the expiration date of the franchise
agreement.
 
ORGANIZATION COSTS
 
    Costs incurred in connection with the organization of the company were
capitalized and are being amortized over five years on a straight-line basis.
 
LONG-LIVED ASSETS
 
    The Company reviews for the impairment of long-lived assets and certain
identifiable intangibles whenever events or changes in circumstances indicate
that the carrying amount of an asset may not be recoverable. No such impairment
indicators have been identified by the Company.
 
INCOME TAXES
 
    The Company recognizes deferred tax liabilities and assets, if any, for the
expected future tax consequences of events that have been included in the
financial statements or tax returns. Under this method, deferred tax liabilities
and assets are determined based on the difference between the financial
statement and tax bases of assets and liabilities using enacted tax rates in
effect for the year in which the differences are expected to reverse. Valuation
allowances are provided when the expected realization of tax assets does not
meet a more likely than not criterion.
 
RECAPITALIZATIONS
 
    On February 17, 1995, the Company effected a 4,000-for-one stock split of
its outstanding shares of common stock. In April 1997, the Company increased its
authorized common stock of $.01 par value to 60,000,000 shares; in addition,
authorized preferred stock with a par value of $.01 was increased to 2,000,000
shares. On April 29, 1997, the Company effected a 3-for-one stock split of its
outstanding shares of common stock. In September 1997, the Company effected a
 .507-for-1 reverse stock split of its common stock. On October 28, 1997, the
total authorized number of shares of common stock of the Company was increased
to 200 million shares, par value $0.01 per share, of which 180 million shares
were designated Class A common stock and 20 million shares were designated Class
B common stock. The accompanying financial statements give retroactive effect to
the above recapitalizations.
 
RECOGNITION OF REVENUE
 
    The Company recognizes revenue on telecommunications services ratably over
the term of the applicable agreements with customers. The Company also provides
installation services for its customers, and as these services typically are
completed within a year, the Company records the revenues and related costs for
these services under the completed contract method.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
STOCK-BASED COMPENSATION
 
    The Company has adopted the disclosure-only provisions of SFAS No. 123,
"Accounting for Stock-Based Compensation." The Company applies APB Opinion No.
25, "Accounting for Stock Issued to Employees," and related interpretations in
accounting for its stock options.
 
CONSULTING AND EMPLOYMENT INCENTIVES
 
    The amounts represent the value of common stock, warrants and options issued
to consultants, officers, employees and directors of the Company as incentive to
provide services to the Company. The 1997 amounts represent the value of options
to purchase 3,095,235 shares of the Company's common stock issued in 1997 to
officers, employees and directors of the Company. The options have been valued
in accordance with APB Opinion No. 25 at the difference between the exercise
price of the options and the fair market value of the Company's common stock.
 
EARNINGS PER SHARE
 
    The Company, as required, adopted SFAS No. 128, "Earnings Per Share," for
the year end 1997. All prior period earnings per share data have been restated.
Net loss per share computations are based upon the net loss attributable to
common shareholders divided by the weighted average number of shares of common
stock outstanding during the respective periods. The effect of stock options and
warrants, using the treasury stock method in computing diluted earnings per
share, is anti-dilutive
 
PREPAID EXPENSES
 
    Non-current prepaid expense mainly represents a prepayment in 1997 to a rail
transportation company which granted the Company a long-term, non-exclusive
right-of-way to place a fiber optic network on a portion of their property.
 
RESTRICTED CASH
 
    In 1997, the Company entered into agreements regarding the issuance of
long-term standby letters of credit with a financial institution whereby the
financial institution required the Company to maintain collateral in the form of
an interest-bearing cash balance with the financial institution in the full
amount of the standby letters of credit issued. The restricted cash is invested
in short-term time deposits of the issuing financial institution and the
interest earned on the time deposits is free of restriction and released to the
Company periodically.
 
DEFERRED REVENUES
 
    Deferred revenue represents prepayments received from customers for future
use of the Company's fiber optic network as well as prepayment for installation
services which have not yet been provided. The Company derives revenues from
leasing dark fiber optic cable. Lease payments are structured as either
prepayments or monthly recurring charges. Prepayments are accounted for as
deferred revenues and recognized over the term of the respective customer lease
agreement. At December 31, 1997, the Company had received prepaid lease payments
totaling $11.5 million.

    a. On April 16, 1996, the Company entered into an agreement with U.S. One
Communications ("U.S. One") for the exclusive usage rights for fibers on the
Company's fiber optic transmission network. The initial term of the agreement
was for a period beginning April 1996 and expiring December 2008. The agreement
was renewable, at the option of U.S. One, for an extended term of 13 years
expiring December 2021. In connection with this agreement, the Company borrowed
$4,900,000 from U.S. One, of which $3,227,867 was immediately used to repay all
notes payable to Tomen America.
 
    On April 30, 1997 the Company amended this agreement which allows U.S. One
to have the exclusive right to use 888 fiber miles of the network. Additionally,
pursuant to the amended agreement, U.S. One received an option to acquire from
the Company up to 1,620 additional fiber miles upon payment of a predetermined
amount. In accordance with the amended agreement the following occurred: (i) all
interest accrued from the inception of the loan to the closing date of the
agreement was waived by U.S. One, and (ii) the $4,900,000 principal balance of
the loan was offset against the $3,530,000 scheduled payment due from U.S. One
to the Company under the amended lease agreement, and (iii) the Company paid to
U.S. One the difference of $1,370,000.
 
    In connection with the execution of the aforementioned lease and financing
agreements, the Company granted U.S. One a warrant to purchase common stock of
the Company. The warrant is exercisable for a number of shares of Class A common
stock to be determined at the Company's discretion subject to a minimum number
of 76,050 shares and maximum number of 456,300 shares. The per share exercise

noteholders which were exercisable for common shares of the Company in an amount
equal to 0.7% of the outstanding shares of common stock immediately following an
initial public offering of the Company's common stock, at an exercise price
equal to 60% of the initial public offering price. These warrants are

initial public offering. In April 1996, the Company offered the warrantholders
shares of common stock equal to 0.7% of the common stock then issued and
outstanding, in exchange for the surrender and cancellation of the outstanding
warrants, and in consideration for the extension of the maturity date of the
notes through June 30, 1996. All of the warrantholders accepted this offer and,
accordingly, the Company issued a total of 59,359 shares of the Company's common
stock. The Company recorded a noncash charge of $107,322 in connection with such
issuance. In 1996, the Company repaid $50,000 of this debt. In 1997, the Company
repaid the outstanding balance of these notes plus all accrued interest.

    Pro forma information regarding net income and earnings per share is
required by Statement of Financial Standards No. 123, "Accounting for
Stock-Based Compensation" ("SAF 123"), and has been determined as if the Company
had accounted for its employees' stock options under the fair value method
provided by that Statement. The fair value of the options was estimated at the
date of grant using the Black-Scholes option pricing model with the following
assumptions for vested and non-vested options:

Dividend yield.............................................................              --
Average life...............................................................         5 years
</TABLE>
 
    The Black-Scholes options valuation model was developed for use in
estimating the fair value of traded options which have no vesting restrictions
and are fully transferable. In addition, option valuation models require the
input of highly subjective assumptions including the expected stock price
volatility. Because the Company's employee stock has characteristics
significantly different from those of traded options, and because changes in the
subjective input assumptions can materially affect the fair value estimate, in
management's option, the existing models do not necessarily provide a reliable
single measure of the fair value of its employee stock options.
 
    For purpose of pro forma disclosures, the estimated fair value of the
options is amortized to expense over the vesting period of the options. The
Company's pro forma information is as follows:

    The weighted average fair value of options granted during the year ended
December 31, 1997 is $3.93. The weighted average remaining contractual life of
options outstanding at December 31, 1997 is 9.4 years.
 
9. INCOME TAXES
 
    There was no provision for federal or state income taxes for the years ended
December 31, 1997, 1996 and 1995. At December 31, 1997, the Company expects to
have available approximately $16,000,000 of net operating loss carryforwards,
expiring in the years 2009 through 2012. The Company has recorded a full
valuation allowance against the deferred tax asset as its realization is
uncertain.

    k. In February 1997, a former investment advisor to the Company asserted a
claim against the Company in the amount of $305,731 pursuant to an agreement
made on June 27, 1995, for the payment of certain fees and expenses. In
September 1997, the Company paid the former investment advisor $250,000 in full
settlement of such claim plus any and all related expenses.
 
    l. On or about April 18, 1997, Howard Katz, Realprop Capital Corporation and
Evelyn Katz commenced an action against, among others, the Company, Stephen A.
Garofalo, Peter Sahagen and Peter Silverman in the United States District Court
for the Southern District Court of New York captioned KATZ, ET AL. V. NATIONAL
FIBER NETWORK, INC., ET AL., No. 97 Civ. 2764 (JGK) (the "Katz Litigation"). On
May 28, 1997, the plaintiffs filed an amended complaint and on September 15,
1997, the plaintiffs filed a second amended complaint. The complaint as amended
alleges causes of action for, among other things, common law fraud, violations
of section 10(b) of the Securities Exchange Act of 1934 and Rule 10b-5
promulgated thereunder, breach of fiduciary duty and negligent misrepresentation
for alleged misrepresentations and omissions made in connection with the
repurchase of a right to purchase an aggregate of 264,631 shares of Class A
common stock of the Company, which class of shares was authorized in October
1997, and an option to purchase warrants for the purchase of 207,888 shares of
Class A common stock. The amended complaint also contains allegations of
corporate waste against the Company and Stephen A. Garofalo. Plaintiffs seek,
among other things, compensatory damages of not less than $12 million, punitive
damages in the amount of $100 million and, in the alternative, rescission of the
purchase of the common stock and warrants by the Company. On October 31, 1997,
all defendants moved to dismiss the amended complaint. The motions were fully
briefed as of December 12, 1997. The Company intends to vigorously defend itself
against these allegations based on its belief that the Company acted
appropriately in connection with the matters at issue in this litigation. No
assurance can be made, though, that the Company will not determine that the
advantages of entering into a settlement outweigh the risk and expense of
protracted litigation or that ultimately the Company will be successful in its
defense of the allegations. If the Company is unsuccessful in its defense of the
allegations, an award of the magnitude being sought by the plaintiffs in the
Katz Litigation would have a material adverse effect on the Company's financial
condition or results of operations.
 
    m. On or about October 20, 1997, Vento & Company of New York, LLC ("VCNY")
commenced an action against the Company, Stephen A. Garofalo, Peter Silverman,
the law firm of Silverman, Collura, Chernis & Balzano, P.C., Peter Sahagen,
Sahagen Consulting Group of Florida (collectively, the "Sahagen Defendants") and
Robert Kramer, Birdie Capital Corp, Lawrence Black, Sterling Capital LLC,

11. COMMITMENTS AND CONTINGENCIES (CONTINUED)
Limited, Needham Capital Group, Arthur Asch, Michael Asch and Ronald Kuzon (the
"Kramer Defendants") in the United States District Court for the Southern
District of New York (No. 97 CIV 7751) (the "VCNY Litigation"). The complaint
alleges causes of action for, among other things, violation of Section 10(b) of
the Securities Exchange Act of 1934 and Rule 10b-5 promulgated thereunder, fraud
and fraudulent concealment, breach of fiduciary duty and negligent
misrepresentation and omission made in connection with the sale by VCNY of
1,368,900 shares of Class A common stock to Peter Sahagen and the Kramer
Defendants on January 13, 1997 (the "VCNY Sale"). The complaint also alleges a
cause of action for declaratory judgment asserting that certain "piggyback"
registration rights are applicable to shares of the Company's Class A common
stock which VCNY owns (or which may be rescinded to VCNY pursuant to its
requested remedies). The complaint further requests a declaratory judgement that
a stockholders' agreement between the Company, Stephen A. Garofalo and VCNY be
declared operative, which agreement indirectly required VCNY, through designated
directors, to approve significant transactions, and, accordingly, the Metromedia
Loan and the Metromedia Investment should be rescinded and Mr. Vento should be
reappointed as Chief Executive Officer of the Company. The Company believes,
among other things, that the stockholder's agreement to which Mr. Vento was a
party had terminated and, as a result, Mr. Vento had no such rights to approve
the Metromedia Investment or the Metromedia Loan or to remain as Chief Executive
Officer of the Company. Plaintiff seeks, among other things, (i) rescission of
the VCNY Sale, or alternatively, damages in an amount not presently
ascertainable, but believed to be in the excess of $36 million, together with
interest thereon, (ii) punitive damages in the amount of $50 million, and (iii)
the declaratory judgements discussed above. The Company intends to vigorously
defend itself against these allegations based on its belief that it acted
appropriately in connection with the matters at issue in this litigation.
However, no assurance can be made that the Company will not determine that the
advantages of entering into a settlement outweigh the risk and expense of
protracted litigation or that ultimately the Company will be successful in its
defense of the allegations. If the Company is unsuccessful in its defense of the
allegations, an award of the magnitude being sought by the plaintiffs in the
VCNY Litigation would have a material adverse effect on the Company's financial
condition or results of operations.

ITEM 9. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS AND FINANCIAL DISCLOSURE.
 
    In September 1996, the Company decided to engage a "big six" accounting firm
and engaged Ernst & Young LLP ("Ernst & Young") to serve as its independent
auditors. Stephen A. Garofalo, majority stockholder, approved the dismissal of
M.R. Weiser & Co. LLP, Certified Public Accountants ("Weiser"), the Company's
former independent auditors, and the engagement of Ernst & Young. At no time
during the periods in which Weiser served as the Company's independent auditors
were there any disagreements between the Company and Weiser regarding any matter
of accounting principles or practices, financial statement disclosure or
auditing scope or procedures. Weiser included in its opinions on the Company's
financial statements a separate paragraph stating that there was substantial
doubt about the Company's ability to continue as a going concern. Ernst &
Young's report on the Company's consolidated financial statements for the years
ended December 31, 1997 and December 31, 1996 does not contain a similar
statement.
 
                                    PART III
 
    The information called for by this Part III (Items 10, 11, 12 and 13) is not
set forth herein because the Company intends to file with the SEC not later than
120 days after the end of the fiscal year ended December 31, 1997 the Definitive
Proxy Statement for the 1998 Annual Meeting of Stockholders to be held on May
18, 1998. Such information to be included in the Definitive Proxy Statement is
hereby incorporated into these Items 10, 11, 12 and 13 by this reference.

                       FIBER LEASE AND INNERDUCT USE AGREEMENT

     This AGREEMENT ("Agreement") is made and entered into as of the 23rd day of
February, 1998, by and between Metromedia Fiber Network, Inc., a Delaware
corporation ("MFN") and NEXTLINK Communications, Inc. ("NEXTLINK"), a Washington
corporation (either MFN or NEXTLINK being referred to in this Agreement as a
"Party," and collectively as the "Parties").

     WHEREAS MFN constructs and maintains a fiber optic cable network and
desires to provide NEXTLINK with long term exclusive use of a portion of this
network subject to the terms and conditions of this Agreement;

     WHEREAS NEXTLINK desires to acquire certain long term rights to use
portions of the MFN System as described herein, subject to the terms and
conditions of this Agreement; and

     WHEREAS NEXTLINK and MFN are increasing the fiber count in NEXTLINK's
network under the New York Fiber Agreement (as defined below);

     NOW, THEREFORE, in consideration of the mutual agreements contained in this
Agreement, the Parties agree as follows.

     ARTICLE I DEFINITIONS

<PAGE>

                                                                               2

     ARTICLE II     TERM AND LEASE

          2.1  LEASE OF FIBERS.  MFN hereby grants to NEXTLINK a lease of the
exclusive use of *** fiber-miles of optical fiber, configured as described in
Exhibit A to this Agreement as of the date of this Agreement and as Exhibit A
may be amended after the date of this Agreement with the agreement of the
Parties and pursuant to Section 2.2, for a Term commencing on the Acceptance
Date for the first segment of NEXTLINK Fibers accepted by NEXTLINK in accordance
with the Acceptance Testing procedures set forth in Section 2.7 ("Acceptance")
and terminating twenty years after the Acceptance Date for the last segment of
NEXTLINK Fibers (the "Term").  MFN shall deliver the NEXTLINK Fibers to NEXTLINK
in logical segments as set forth on Exhibit A.  This lease shall provide
NEXTLINK with quiet enjoyment of the NEXTLINK Fibers for the Term.  If MFN, in
its sole discretion, extends or renews any underlying right-of-way relating to
the NEXTLINK Fibers beyond the Term, NEXTLINK shall have the right to extend the
Term of the fiber lease for a term corresponding to such extension or renewal
(up to two additional ten-year periods), upon notice to MFN not less than 180
days prior to the expiration of the then-current term. The consideration payable
for any extensions of the Term shall be as stated in Section 3.1. MFN shall
promptly notify NEXTLINK of the expiration dates for rights-of-way relevant to
this Agreement. In the event that NEXTLINK desires to extend the fiber lease, it
shall give notice to MFN no sooner than two years, and no later than one year,
prior to the expiration of the Term (the "Extension Notice").  Within 60 days
after the date of the Extension Notice MFN shall give notice to NEXTLINK
advising NEXTLINK whether or not it intends to renew any relevant rights-of-way.
If MFN does not intend to extend or renew such right-of-way, NEXTLINK shall have
the right to negotiate directly with the holder of any right-of-way for a new
right-of-way.  If MFN elects not to renew or extend a right-of-way and intends
to abandon the use of the NEXTLINK Fibers in such right-of-way, MFN shall, upon
NEXTLINK's request, convey title to such NEXTLINK Fibers to NEXTLINK in exchange
for a payment of $100.00 by NEXTLINK.

          2.2  DESCRIPTION OF NEXTLINK FIBERS.  Exhibit A in the form attached
to this Agreement on the date of this Agreement identifies the type of fiber and
configuration for fiber miles to be leased by NEXTLINK.  Exhibit A also states
MFN's anticipated construction schedule for the NEXTLINK Fibers.  For a period
of 90 days after the date of this Agreement, NEXTLINK shall have the right (with
the consent of MFN, which shall not be unreasonably withheld or delayed by MFN)
to change the fiber count for particular segments as designated on Exhibit A as
long as the total fiber miles to be changed does not exceed 25% of the total
fiber miles to be leased pursuant to Section 2.1.  MFN shall use commercially
reasonable efforts to deliver the NEXTLINK Fibers to NEXTLINK on the schedule
set forth in Exhibit A.  NEXTLINK acknowledges, however, that MFN does not
guarantee delivery of the NEXTLINK Fibers to NEXTLINK on the dates set forth on
such schedule.

          2.3  LONG-HAUL INNERDUCT.  MFN hereby grants to NEXTLINK an exclusive,
indefeasible right of use ("IRU"), for a single, one and one-quarter inch 

<PAGE>

                                                                              3

(11/4") vacant innerduct (the "Long-Haul Innerduct") throughout the entire route
described on Exhibit B-4 (the "Long-Haul Route") for a term ending (with respect
to any particular segment) with the expiration of the underlying right-of-way
for that segment (or, in the case of right-of-way held by Consolidated Rail
Corporation, a term ending with the expiration of the first ten-year "Extension
Term" under MFN's agreement with Consolidated Rail Corporation).  This IRU shall
commence upon NEXTLINK's Acceptance of the Long-Haul Innerduct. This IRU shall
provide NEXTLINK with quiet enjoyment of the Long-Haul Innerduct for the term
ending as stated above in Section 2.3.  NEXTLINK shall have the right to extend
the term for this IRU for a term ending with the expiration of the underlying
right-of-way for any particular segment, if renewed or extended by MFN in its
discretion from time to time, at no additional consideration other than for
maintenance charges and MFN's incremental share of right-of-way fees as stated
in Section 3.2.  The Long-Haul Innerduct shall meet the specifications stated on
Exhibit B and shall include fiber-drop or splice points at locations shown on
Exhibit B or otherwise agreed upon by the Parties.  MFN shall deliver to
NEXTLINK such evidence of the grant of the IRU for the Long-Haul Innerduct (on
the terms stated in this Agreement) as NEXTLINK may reasonably request upon
Acceptance of the Long-Haul Innerduct by NEXTLINK.  The Long-Haul Innerduct
shall be completed and made available for delivery to NEXTLINK in the logical
sequences shown on Exhibit B, no later than the dates set forth on Exhibit C. 
MFN shall grant this IRU for segments of the Long-Haul Innerduct as such
segments are completed rather than waiting for completion of the entire Long-
Haul Innerduct. NEXTLINK shall, not later than the next business day after
NEXTLINK's Acceptance of any segment of the Long-Haul Innerduct, instruct the
Escrow Agent (as defined below) to release funds from escrow calculated at the
rate of *** per mile of Long-Haul Innerduct.  Together with the IRU for the
Long-Haul Innerduct, MFN shall use commercially reasonable efforts to grant
NEXTLINK either a lease or IRU for innerduct from MFN's Jersey City, New Jersey
point of presence to MFN's New York, New York point of presence at 60 Hudson
Street, as further described on Exhibit B for the term of the IRU set forth in
this paragraph.  If MFN is unable to grant such lease or IRU, MFN shall grant
NEXTLINK a lease of fibers from Jersey City, New Jersey to New York, New York. 
The lease of fibers in this segment from Jersey City to New York shall include
the same number of fiber strands that are installed for NEXTLINK's use in the
adjoining portions of the Long-Haul Innerduct. NEXTLINK shall directly pay for
the fibers to be installed in the Jersey City to New York segment, or reimburse
MFN for MFN's cost to purchase the fibers, and NEXTLINK shall also pay directly,
or reimburse MFN for, MFN's cost to install the fibers.  These fiber miles do
not reduce the fiber miles to be leased by NEXTLINK under Section 2.1.

          The grant of the IRU described in this Section 2.3 is subject to (i)
MFN's receipt of any necessary consents of holders of underlying rights-of-way
required for such IRU , (ii) NEXTLINK entering into such agreement as the holder
of the underlying right-of-way may reasonably request, and (iii) to NEXTLINK's
approval of the amount of right-of-way fees or other fees to be incurred by
NEXTLINK with respect to the Long-Haul Innerduct and of the terms of all
rights-of-way applicable to the Long-Haul 

<PAGE>

                                                                              4

Innerduct.  The Parties shall cooperate in good faith, using their respective
commercially reasonable efforts, to obtain the necessary consents or agreements
from holders of underlying rights-of-way.  If such consents have not been
obtained within one year after the date of this Agreement, or if NEXTLINK has
not approved the amount of the right-of-way fees or other fees to be incurred by
NEXTLINK and the terms of all rights of way applicable to the Long-Haul
Innerduct within one year after the date of this Agreement, then either Party
may, by written notice to the other Party, terminate the Parties' Agreement for
the IRU under this Section 2.3.  Upon such termination, NEXTLINK shall have the
right to select one of the following options, which shall be determined by
NEXTLINK as soon as practical after such termination: (a) NEXTLINK may elect to
terminate the portion of this Agreement relating to the grant of the IRU
pursuant to this Section 2.3 and pay MFN an additional $4,000,000 in
consideration of the fiber lease described in Section 2.1, by deposit into
escrow under the Escrow Agreement (as defined below), which $4,000,000 shall be
disbursed over time upon Acceptance of segments of the NEXTLINK Fibers, in
proportion to the number of fiber miles in such segment compared with the
then-remaining number of fiber miles of NEXTLINK Fibers yet to be delivered; or
(b) if MFN is permitted to pull additional fiber in the Long-Haul Route,
NEXTLINK may (to the extent MFN is permitted to do so under applicable
right-of-way agreements) require MFN to grant NEXTLINK a lease or IRU for the
number of strands requested by NEXTLINK, up to a maximum of 432 strands of fiber
throughout the Long-Haul Route for a one-time payment of *** per fiber mile that
is subject to such lease or IRU (less all amounts released to MFN from escrow,
and the down payment made by NEXTLINK, with respect to the Long-Haul Innerduct),
or (c) if MFN is not permitted to pull additional fiber in the Long-Haul Route,
NEXTLINK may require MFN to lease to NEXTLINK up to 96 strands of fiber for a
one-time lease payment of *** per fiber mile (less all amounts released to MFN
from escrow, and the down payment made by NEXTLINK, with respect to the
Long-Haul Innerduct).  The lease or IRU granted under clause (b) and the lease
granted under clause (c) shall expire on expiration of the IRU for the Long-Haul
Innerduct.

          2.4  ADDITIONAL INNERDUCT.  In the event MFN owns innerduct or the
equivalent in any portion of the route of the NEXTLINK Fibers, and MFN elects to
offer such innerduct or equivalent to NEXTLINK, such election to be in MFN's
sole discretion, and if NEXTLINK elects to accept such offer, such election to
be in NEXTLINK's sole discretion, MFN shall grant NEXTLINK a 20-year IRU for an
additional single, one and one-quarter inch (11/4") vacant innerduct (the
"Additional Innerduct"), or equivalent raceway space, in the route agreed to in
writing by the Parties. MFN shall deliver to NEXTLINK such evidence of the grant
of the IRU for the Additional Innerduct (on the terms stated in this Agreement)
as NEXTLINK may reasonably request upon Acceptance of the Additional Innerduct
by NEXTLINK.  The Additional Innerduct shall meet the specifications stated in
Exhibit B with respect to the type, quality and other specifications.  NEXTLINK
shall have the right to extend the Term for this IRU for a term ending with the
expiration of the underlying right-of-way for any particular segment, as renewed
or extended by MFN from time to time, at no 

<PAGE>

                                                                              5

additional consideration other than for maintenance charges and incremental
share of right-of-way fees as stated in Section 3.3.

          2.5  INSTALLATION OF FIBER IN LONG-HAUL INNERDUCT.  NEXTLINK shall
give MFN not less than ninety days written notice prior to the date NEXTLINK
desires to have installation of fiber in the Long-Haul Innerduct commence. 
NEXTLINK shall select a contractor from a list of contractors approved by MFN to
install such fiber.  At NEXTLINK's option, NEXTLINK may require such contractors
to participate in a competitive-bid process prior to selection of the
contractor.  NEXTLINK shall pay the cost charged by such contractor for the
installation.   MFN shall have the right to manage and supervise the
installation.  NEXTLINK shall reimburse MFN for MFN's reasonable costs for time
spent  in such management and supervision, as set forth in invoice from MFN to
NEXTLINK showing in reasonable detail the time spent by MFN personnel. 
NEXTLINK's notice regarding the installation shall designate the number of
strands that NEXTLINK intends to have installed in such Long-Haul Innerduct.  By
written notice to NEXTLINK within thirty days after such notice from NEXTLINK,
MFN may exercise its option to require NEXTLINK to lease to MFN fiber in one or
more segments of the Long-Haul Innerduct as stated in this Section 2.5.  If MFN
fails to provide such notice to NEXTLINK, MFN shall have no right to require
NEXTLINK to lease to MFN fibers in any innerduct.  NEXTLINK shall, at MFN's
request, include in the single bundle of fibers installed in such innerduct a
minimum of 96 additional strands of fiber.  Subject to the foregoing, if
NEXTLINK has fewer 336 fibers installed in such Long-Haul Innerduct, MFN shall
have the right to increase the number of strands to be installed for MFN by
NEXTLINK above 96 such that a total of up to 432 strands will be installed in
the Long-Haul Innerduct.  NEXTLINK shall lease such fibers to MFN for a period
equal to the remaining term on NEXTLINK's IRU for the Long-Haul Innerduct (as
extended or renewed) with no lease payment due from MFN to NEXTLINK.  The lease
shall commence on delivery of the fiber strands to MFN.

          2.6  COLLOCATION.  The Parties shall consult and negotiate with each
other with respect to collocation space, regeneration sites and the like,
including possible swaps of collocation space and regeneration sites.  Any
agreement between the Parties with respect thereto shall be in writing and shall
state the pricing terms.

          2.7  SPLICING; ACCEPTANCE TESTING.  MFN shall, at NEXTLINK's request,
provide such services as shall be necessary to connect the NEXTLINK Fibers,
Long-Haul Innerduct and Additional Innerduct and spurs, laterals, subrings and
other network assets (including regeneration equipment) on and after the
Acceptance Date at splice points and other appropriate points identified on
Exhibits A and B, and also as requested by NEXTLINK at other technically
feasible locations, with the consent of MFN, which consent shall not be
unreasonably withheld or delayed by MFN.  NEXTLINK shall have the right to
supervise such work, at NEXTLINK's expense.  NEXTLINK shall reimburse MFN for
MFN's reasonable costs in performing such services.

                                                                              6

               (a)  MFN shall test all NEXTLINK Fibers, Long-Haul Innerduct and
Additional Innerduct in accordance with the specifications stated in the
Exhibits to this Agreement ("Acceptance Testing") to verify that such the
NEXTLINK Fibers, Long-Haul Innerduct and Additional Innerduct are installed in
compliance with the specifications described in the applicable Exhibits. 
Acceptance Testing shall progress span by span along each segment as cable
splicing or other installation progresses, so that test results may be reviewed
in a timely manner.  Where practical, MFN shall provide NEXTLINK at least ten
(10) business days advance notice, but in any case at least five (5) business
days advance notice, of the date and time of each Acceptance Testing (each of
which shall take place during normal business hours where practical) such that
NEXTLINK shall have the right, but not the obligation, to have a person or
persons present to observe MFN's Acceptance Testing.  When MFN has determined
that the results of the Acceptance Testing with respect to a particular span
show that the NEXTLINK Fibers, Long-Haul Innerduct or Additional Innerduct so
tested are installed and in compliance with the applicable specifications set
forth in the Exhibits to this Agreement, MFN shall promptly provide NEXTLINK
with a copy of such test results.

               (b)  When MFN reasonably determines the NEXTLINK Fibers,
Long-Haul Innerduct or Additional Innerduct with respect to an entire segment
are installed substantially in conformity with the applicable specifications set
forth in the Exhibits to this Agreement, MFN shall promptly provide written
notice of completion to NEXTLINK (a "Completion Notice").  NEXTLINK shall,
within fourteen (14) days of receipt of the Completion Notice, either reject the
Completion Notice specifying the defect or failure in such Acceptance Testing or
give MFN written notice of acceptance of such Acceptance Testing (the period
from the date of NEXTLINK's receipt of the Completion Notice to the date of
MFN's receipt of NEXTLINK's notice of rejection or Acceptance being referred to
herein as the "Review Period").  In the event NEXTLINK rejects the Completion
Notice, MFN shall promptly, and not later than fourteen (14) days after receipt
of NEXTLINK's notice of rejection, and at no cost to NEXTLINK, commence to
remedy the defect or failure.  Thereafter, upon completion of the remediation of
the defect or failure, MFN shall again give NEXTLINK a Completion Notice.  The
foregoing procedure shall apply again and successively thereafter for a total of
two attempts to remedy the defect or failure.  If MFN fails to adequately remedy
or cure the defect or failure after two attempts, NEXTLINK shall have the right
to proceed promptly and in an economically efficient manner for a period of up
to thirty days to cure such defects or failures at MFN's cost and expense, which
shall be paid by MFN to NEXTLINK upon demand, or at the election of NEXTLINK
offset from any payment by NEXTLINK to MFN under this Agreement.  No acceptance
of, or failure by NEXTLINK to reject, the Completion Notice shall be deemed to
be a waiver of any rights or remedies of NEXTLINK under this Agreement; provided
that NEXTLINK's use of the fiber or Innerduct in question (other than in
connection with testing) and any failure by NEXTLINK to timely reject as set
forth above shall be deemed Acceptance for purposes of this Agreement.  The date
when NEXTLINK accepts or is deemed to have accepted a Completion Notice or cures
such defects at MFN'S cost and expense as provided above with respect to any
portion of the NEXTLINK Fibers is herein defined 

<PAGE>

                                                                              7

as the "Acceptance Date."  Not later than the business day following the
Acceptance Date, NEXTLINK shall cause the Escrow Agent to release from escrow a
portion of the funds held by the Escrow Agent under the Escrow Agreement, in the
amount designated by the Parties in the applicable Exhibits corresponding to the
segment being accepted by NEXTLINK.

          2.8  REMOVAL ON TERMINATION.  Upon the expiration of the fiber lease
and IRUs provided to NEXTLINK in this Agreement, or any earlier termination of
this Agreement, NEXTLINK shall exercise commercially reasonable efforts to
remove all NEXTLINK property from the MFN System and reroute NEXTLINK's traffic
within sixty (60) days from such expiration or termination and shall complete
such removal in a manner that does not interfere with or damage the MFN System. 
In the event that NEXTLINK fails to remove its property within such period, MFN
may remove and store the NEXTLINK property at NEXTLINK's expense.

          2.9  CONSTRUCTION STANDARDS.  All construction required for
performance by MFN of its obligations under this Agreement shall be performed in
accordance with the terms stated in any Exhibit to this Agreement and in
accordance with industry standards.

          2.10 COOPERATION IN PLANNING.  The Parties shall cooperate in good
faith in planning the design and construction of the NEXTLINK Fibers, the
Long-Haul Innerduct and the Additional Innerduct.  Not less frequently than once
every six months, NEXTLINK and MFN shall meet to evaluate MFN's construction
plans and network design and to consider NEXTLINK's comments and requests for
modifications.  Except as may be requested to comply with the applicable
specifications stated in this Agreement or an Exhibit to this Agreement, MFN
shall not have any obligation to make modifications requested by NEXTLINK.  MFN
shall promptly notify NEXTLINK of any material deviation from the route design
previously proposed by MFN for any particular segments and NEXTLINK shall have
the right to withdraw from participation in the affected portion of the route
and the right to designate (in a commercially reasonable manner) replacement
fibers in technically feasible locations.  To the extent technically feasible
and commercially reasonable, however, MFN shall add additional splice points and
make other changes requested by NEXTLINK (at NEXTLINK's expense), provided that
NEXTLINK responds with such requests within the time periods reasonably
determined from time to time by MFN (and given to NEXTLINK in writing) based on
MFN's construction schedule.

          2.11 INCREASE IN NEW YORK FIBERS.  As part of the consideration
NEXTLINK is receiving under this Agreement, MFN shall increase the fiber count
for the "Leased Fibers" as defined in the New York Fiber Agreement by the number
of  fiber miles equivalent to the number of fiber miles required to increase the
fiber count for such "Leased Fibers" to *** fibers in all segments of such
"Leased Fibers."  The specific fiber counts by segment shall be as stated by
NEXTLINK in a written request to MFN within 90 days after the date of this
Agreement, with the consent of MFN 

<PAGE>

                                                                              8

(which shall not be unreasonably withheld or delayed by MFN).  This Section 2.11
shall not obligate MFN to install these additional strands of fiber in any
particular location unless MFN is obligated to lease to NEXTLINK fiber at that
location under the New York Fiber Agreement.  No additional payment shall be due
from NEXTLINK under this Agreement or the New York Fiber Agreement as a result
of such increase in the fiber count for such Leased Fibers.  Such increase in
fiber count shall not reduce the fiber-miles NEXTLINK is entitled to lease under
Section 2.1 of this Agreement.

          2.12 NEXTLINK and MFN agree that the lease to MFN contemplated under
Section 2.5 and the provision of additional fiber to NEXTLINK contemplated under
Section 2.11 are of equivalent value and are valued at Four Million Four Hundred
Thousand Dollars ($4,400,000).

     ARTICLE III    TERMS OF PAYMENT

          3.1  FIBER LEASE PAYMENT.  In consideration of the lease of fibers set
forth in Section 2.1, NEXTLINK shall pay MFN a one-time lease payment of $***. 
This lease payment shall be paid as follows: on the third business day following
the execution of this Agreement by both parties, NEXTLINK shall pay the sum of
$*** by wire transfer directly to MFN.  Within five days after the execution by
the Parties and the Escrow Agent (as defined in Section 3.4) of the Escrow
Agreement (as defined in Section 3.4) NEXTLINK shall pay the balance of $*** by
wire transfer to the Escrow Agent identified in Section 3.4 below.  The funds in
escrow shall be released from escrow as segments of the NEXTLINK Fibers are
accepted by NEXTLINK.   If the Term is extended as provided in Section 2.1, the
lease payment for such extended term shall be determined at a rate equal to 35%
of the fair market value of the fiber lease at the commencement of each
extension, plus payment of MFN's maintenance charges at market rates and
increases in right-of-way fees.  No monthly charges or other recurring charges
shall be due from NEXTLINK in connection with the lease or maintenance of the
NEXTLINK Fibers (except for maintenance required (i) at NEXTLINK's request, but
not required for compliance with the specifications stated in this Exhibits to
this Agreement, or (ii) as a result of NEXTLINK's acts or omissions.

          3.2  LONG-HAUL INNERDUCT PAYMENT.  In consideration of the grant of
the IRU for the Long-Haul Innerduct set forth in Section 2.3, NEXTLINK shall pay
MFN a one-time payment of $***.  This payment shall be made as follows: on the
third business day following the execution of this Agreement by both parties,
NEXTLINK shall pay the sum $*** by wire transfer directly to MFN.  Within five
days after the execution of the Escrow Agreement by the Parties and the Escrow
Agent, NEXTLINK shall pay the balance of $*** by wire transfer to the Escrow
Agent identified in Section 3.4 below.  NEXTLINK shall instruct the Escrow Agent
to release $*** (in increments of $*** with respect to the CSX right-of-way and
$*** with respect to the Conrail right-of-way) to MFN promptly after MFN obtains
any necessary consents of holders of rights-of-way under Section 2.3, and
NEXTLINK has approved the amount of right-of-way fees or other fees to be
incurred by NEXTLINK with respect to the Long-Haul Innerduct and 

<PAGE>

                                                                              9

NEXTLINK has approved the terms of all right-of-way agreements NEXTLINK is
required to enter into with respect to the Long-Haul Innerduct and the terms of
any consent given by any holder of such right-of-way.  The balance of the funds
in escrow shall be released from escrow as segments of the Long-Haul Innerduct
are accepted by NEXTLINK.  No monthly charges or other recurring charges shall
be due from NEXTLINK in connection with the IRU for the Long-Haul Innerduct.
NEXTLINK shall be responsible for payment of maintenance costs with respect to
such Long-Haul Innerduct, by hiring MFN to maintain such Long-Haul Innerduct and
paying MFN's reasonable charges for such maintenance.  For a period of two years
after NEXTLINK's Acceptance of the Long-Haul Innerduct, such maintenance charges
shall be calculated at a rate of $200.00 per year per route mile.  Such
maintenance charges shall increase or decrease thereafter based on MFN's actual
maintenance costs, as may be agreed by the Parties at the time or, failing such
agreement of the Parties, pursuant to the dispute resolution process set forth
in this Agreement. NEXTLINK shall pay MFN for Emergency Unscheduled Maintenance
on a time and materials basis.  If any additional right-of-way fees or other
fees are imposed on MFN by the holder of the underlying right-of-way or other
third party as a result of the installation or use by NEXTLINK of the Long-Haul
Innerduct, NEXTLINK shall pay such additional fees either directly or on a
pass-through basis to MFN.  For any pass-through payment, NEXTLINK shall have
the right to receive evidence reasonably satisfactory to NEXTLINK that such
additional fees were actually paid by MFN, or are payable by MFN, with respect
to the installation (or use by NEXTLINK) of the Long-Haul Innerduct.  If MFN
exercises its right under Section 2.5 to include fiber in the Long-Haul
Innerduct, NEXTLINK's share of expenses for maintenance and right-of-way fees
under this Section 3.2 shall be reduced Pro Rata.  No additional payment shall
be required from NEXTLINK for any renewal or extension of the IRU for the
Long-Haul Innerduct, but NEXTLINK shall continue to pay for maintenance as
required and other fees under this Section 3.2 and shall pay its pro rata share
of any increase right-of-way or other fees incurred by MFN as a result of such
renewal or extension of the right-of-way.  

          3.3  ADDITIONAL INNERDUCT PAYMENT.  In consideration of the grant of
any IRU for the Additional Innerduct set forth in Section 2.4, NEXTLINK shall
pay MFN a one-time fee equal to *** per mile, rounded up or down to the nearest
mile based on the total number of miles of Additional Innerduct granted to
NEXTLINK.  This payment shall be paid directly to MFN at the time NEXTLINK
accepts delivery of the Additional Innerduct.  No monthly charges or other
recurring charges shall be due from NEXTLINK in connection with the grant of the
IRU with respect to the Additional Innerduct.  NEXTLINK shall be responsible for
payment of maintenance costs with respect to such Additional Innerduct, by
hiring MFN to maintain such Additional Innerduct and paying MFN's reasonable
charges for such maintenance.  Such maintenance charges shall be calculated at
the rate per year per route mile applicable under Section 3.2 at the time.
NEXTLINK shall pay MFN for Emergency Unscheduled Maintenance on a time and
materials basis.  If any additional right-of-way fees or other fees are imposed
on MFN by the holder of the underlying right-of-way as a result of the
installation (or use by NEXTLINK) of the Additional Innerduct, NEXTLINK shall
pay 

<PAGE>

                                                                             10

such additional fees either directly or on a pass-through basis to MFN.  For any
pass-through payment, NEXTLINK shall have the right to receive evidence
reasonably satisfactory to NEXTLINK that such additional fees were actually paid
by MFN, or are payable by MFN, with respect to the installation of the
Additional Innerduct. No additional payment shall be required from NEXTLINK for
any renewal or extension of the IRU for the Additional Innerduct, but NEXTLINK
shall continue to pay for maintenance as required in this Section 3.3 and shall
pay its pro rata share of any increase right-of-way or other fees incurred by
MFN as a result of such renewal or extension of the right-of-way. 

          3.4  ESCROW.  Promptly after the execution of this Agreement, the
Parties shall enter an Escrow Agreement substantially in the form attached as
Exhibit G hereto (the "Escrow Agreement"), with such changes as may be
reasonably requested by the Escrow Agent.  Pursuant to the Escrow Agreement,
NEXTLINK shall make deposits as set forth in this Article III to an escrow
account established with First Trust National Association or other escrow agent
satisfactory to both Parties (the "Escrow Agent").  The Escrow Agreement shall
authorize the Escrow Agent to remit the Escrow Deposit (as defined in the Escrow
Agreement), when the conditions precedent to such payments, as provided herein,
are satisfied.

          3.5  PAYMENT BY MFN.  MFN shall pay NEXTLINK for MFN's pro rata share
of the additional costs for materials and right-of-way fees and similar fees
(other than labor) that NEXTLINK incurs as a result of MFN's exercise of its
rights under Section 2.5.

     ARTICLE IV     MAINTENANCE AND REPAIR OF THE NEXTLINK FIBERS

          4.1  ROUTINE MAINTENANCE.  Routine maintenance and repair of the
NEXTLINK Fibers described in Section 2.1 ("Scheduled Maintenance") shall be
performed at MFN's expense by or under the direction of MFN.  Scheduled
Maintenance shall commence with respect to each segment upon the Acceptance Date
for such segment.  All scheduled maintenance shall be performed in accordance
with industry standards and in compliance with MFN's standard maintenance
procedures.

          4.2  UNSCHEDULED MAINTENANCE.  Non-routine maintenance and repair of
the NEXTLINK Fibers which is not included as Scheduled Maintenance ("Unscheduled
Maintenance"), shall be performed at MFN's expense (except to the extent caused
by the acts or omissions of NEXTLINK) by or under the direction of MFN. 
Unscheduled Maintenance shall commence with respect to each segment upon the
Acceptance Date for such segment.  Unscheduled Maintenance shall consist of:

               (a)  "Emergency Unscheduled Maintenance" in response to an alarm
identification by MFN's Operations Center, notification by NEXTLINK or
notification by any third party of any failure, interruption or impairment in
the operation 

<PAGE>

                                                                             11

of the NEXTLINK Fibers, or any event imminently likely to cause the failure,
interruption or impairment in the operation of the NEXTLINK Fibers.

               (b)  "Non-Emergency Unscheduled Maintenance" in response to any
potential service-affecting situation to prevent any failure, interruption or
impairment in the operation of the NEXTLINK Fibers.

          NEXTLINK shall promptly report the need for Unscheduled Maintenance to
MFN in accordance with procedures promulgated by MFN from time to time.  MFN
will log the time of NEXTLINK's report, verify the problem and will dispatch
personnel promptly (and as provided in Section 4.3) to take corrective action. 
If NEXTLINK has caused the problem giving rise to the Unscheduled Maintenance,
NEXTLINK shall reimburse MFN for MFN's reasonable costs (on a time and materials
basis) with respect to such problem.

          4.3  OPERATIONS CENTERS.  MFN shall operate and maintain one or more
Operations Centers ("OCs") staffed twenty-four hours a day, seven (7) days a
week by trained and qualified personnel beginning with the earliest Acceptance
Date under this Agreement.  Qualified maintenance personnel shall be available
for dispatch twenty-four (24) hours a day, seven (7) days week.  MFN shall use
its best efforts to have its first maintenance representative at the site
requiring Emergency Unscheduled Maintenance activity within two (2) hours after
the time MFN becomes aware of an event requiring Emergency Unscheduled
Maintenance.  MFN shall maintain a telephone number through which NEXTLINK may
contact personnel at an OC without toll from the New York metropolitan area. 
MFN's OC personnel shall dispatch maintenance and repair personnel along the
system to handle and repair problems detected in the NEXTLINK Fibers, (i)
through NEXTLINK's remote surveillance equipment and upon notification by
NEXTLINK to MFN, or (ii) upon notification by a third party.

          4.4  COOPERATION AND COORDINATION.  NEXTLINK shall utilize an
Operations Escalation List, as updated from time to time, to report and seek
immediate initial redress of exceptions noted in the performance of MFN in
meeting maintenance service objectives.  NEXTLINK will, as necessary, arrange
for escorted access for MFN to all sites of the NEXTLINK Fibers, subject to
applicable contractual underlying real property and other third-party
limitations and restrictions.  In performing its services hereunder, MFN shall
take workmanlike care to prevent impairment to the signal continuity and
performance of the NEXTLINK Fibers.  The precautions to be taken by MFN shall
include notification to NEXTLINK.  In addition, MFN shall reasonably cooperate
with NEXTLINK in sharing information and analyzing the disturbances regarding
the cable and/or fibers.  In the event that any Scheduled or Unscheduled
Maintenance hereunder requires a traffic roll or reconfiguration involving
cable, fiber, electronic equipment, or regeneration or other facilities of
NEXTLINK, then NEXTLINK shall, at MFN's reasonable request, make such personnel
of NEXTLINK available as may be necessary in order to accomplish such
maintenance, which personnel shall coordinate and cooperate with MFN in
performing such maintenance as required 

<PAGE>

                                                                             12

of MFN hereunder.  MFN shall use its best efforts to notify NEXTLINK at least
five business days prior to the date of any Scheduled Maintenance on any
NEXTLINK Fibers and as soon as possible after becoming aware of the need for
Unscheduled Maintenance.  NEXTLINK shall have the right to be present during the
performance of any Scheduled Maintenance on any NEXTLINK Fibers or Unscheduled
Maintenance so long as this requirement does not interfere with MFN's ability to
perform its obligations under this Agreement.  In the event that Scheduled
Maintenance is canceled or delayed for whatever reason as previously notified,
MFN shall notify NEXTLINK at MFN's earliest opportunity, and will comply with
the provisions of the previous sentence to reschedule any delayed activity.

          4.5  FACILITIES.  MFN shall maintain the NEXTLINK Fibers in a manner
that will permit NEXTLINK's use, in accordance with the terms and conditions of
this Agreement, of the NEXTLINK Fibers and associated facilities required to be
provided under the terms of this Agreement.  Except to the extent otherwise
expressly provided in this Agreement, NEXTLINK will be solely responsible for
providing and paying for any and all maintenance of all electronic, optronic and
other equipment, materials and facilities used by NEXTLINK in connection with
the operation of the NEXTLINK Fibers, none of which is included in the
maintenance services to be provided hereunder.

          4.6  FIBERS.  MFN shall perform appropriate Scheduled Maintenance on
the cable containing the NEXTLINK Fibers in accordance with MFN's then current
preventative maintenance procedures as agreed to by NEXTLINK, which shall not
substantially deviate from standard industry practice.  MFN shall maintain
sufficient capability to teleconference with NEXTLINK during an Emergency
Unscheduled Maintenance in order to provide regular communication during the
repair process.  When correcting or repairing cable discontinuity or damage,
including but not limited to in the event of Emergency Unscheduled Maintenance,
MFN shall use reasonable efforts to repair traffic-affecting discontinuity
within four (4) hours after the MFN maintenance employee's arrival at the
problem site.  In order to accomplish such objective, it is acknowledged that
the repairs so effected may be temporary in nature.  In such event, within
twenty-four (24) hours after completion of any such Emergency Unscheduled
Maintenance, MFN shall commence its planning for permanent repair, and
thereafter promptly shall notify NEXTLINK of such plans, and shall implement
such permanent repair within an appropriate time thereafter.  Restoration of
open fibers on fiber strands not immediately required for service shall be
completed on a mutually agreed-upon schedule.  If the fiber is required for
immediate service, the repair shall be scheduled for the next available Planned
Service Work Period ("PSWP").  In performing repairs, MFN shall comply with the
splicing specifications as set forth in Exhibit E.  MFN shall provide to
NEXTLINK any modifications to these specifications as may be necessary or
appropriate in any particular instance for NEXTLINK's approval, which approval
shall not be unreasonably withheld.  MFN's representatives that are responsible
for initial restoration of a cut cable shall carry on their vehicles the
typically appropriate equipment that would enable a temporary splice, with the
objective of restoring operating capability in as little time as possible.  MFN
shall maintain and supply an inventory of spare cable 

<PAGE>

                                                                             13

in storage facilities supplied and maintained by MFN at strategic locations to
facilitate timely restoration.

          4.7  PLANNED SERVICE WORK PERIOD ("PSWP").  Scheduled Maintenance that
is reasonably expected to produce any signal discontinuity must be coordinated
between the parties. Generally, this work should be scheduled after midnight and
before 6:00 a.m. local time.  Major system work such as fiber rolls and hot cuts
will be scheduled for PSWP weekends.  A calendar showing approved PSWP will be
agreed upon in the last quarter of every year for the year to come.  The intent
is to avoid jeopardy work on the first and last weekends of the month and
high-traffic holidays.

          4.8  RESTORATION.  MFN shall use its best efforts to respond to any
interruption of service or a failure of the NEXTLINK Fibers to operate in
accordance with the specifications set forth in the applicable Exhibits to this
Agreement (in any event, an "Outage") as quickly as possible in accordance with
the procedures set forth herein.  When restoring a cut cable in the NEXTLINK
Fibers, the parties agree to work together to restore all traffic as quickly as
possible.  MFN, promptly upon arriving on the site of the cut, shall determine
the course of action to be taken to restore the cable and shall begin
restoration efforts.  MFN shall splice fibers tube by tube or ribbon by ribbon,
rotating between tubes or ribbons operated by any fiber lessees or holders of
IRUs (collectively, "Interest Holders"), including NEXTLINK, in accordance with
the following described priority and rotation mechanics; provided that, lit
fibers in all buffer tubes or ribbons shall have priority over any dark fibers
in order to allow transmission systems to come back on line; and provided
further that MFN will continue such restoration efforts until all lit fibers in
all buffer tubes or ribbons are spliced and all traffic restored.  In general,
priority among Interest Holders affected by a cut shall be determined on a
rotating restoration-by-restoration and segment-by-segment basis, to provide
fair restoration to all Interest Holders.  However, MFN shall establish a
Priority Customer Grouping ("PCG") which will receive, whenever possible,
priority in the restoration of tubes or ribbons that affect their use of MFN
facilities.  NEXTLINK shall be a member of the PCG.  The goal of emergency
restoration splicing shall be to restore service as quickly as possible.  This
requires the use of some type of mechanical splice, such as the "3M Fiber Lock"
to complete the temporary restoration.  Permanent restorations will take place
as soon as possible after the temporary splice is complete.

          4.9  STANDARDS; SUBCONTRACTING.  All Scheduled Maintenance shall be
performed in accordance with industry standards and in compliance with the
Standards observed by MFN in its maintenance on any other similar MFN assets. 
MFN may subcontract any of the maintenance services hereunder; provided that MFN
shall require the subcontractor(s) to perform in accordance with the requirement
and procedures set forth herein and all applicable industry standards.  The use
of any such subcontractor shall not relieve MFN of any of its obligations
hereunder.

          4.10 FIBER REPLACEMENT.  In the event all or any part of the NEXTLINK
Fibers shall require replacement during the term of this Agreement, such
replacement 

<PAGE>

                                                                             14

shall be made as soon as reasonably practical, at MFN's sole cost and expense;
except, however, if the replacement of the NEXTLINK Fibers is required as a
result of the acts or omissions of NEXTLINK, MFN shall make such replacement at
NEXTLINK's cost and expense on a time and materials basis.

          4.11 OUTAGES.  During the Term of this Agreement, MFN shall refund to
NEXTLINK, the amounts set forth in Exhibit H hereto, as compensation for
"Outages."  Payment of such amounts shall be NEXTLINK's sole remedy for such
Outages.  For the purposes of this Agreement, an Outage is the complete
interruption of service over any fiber circuit in the NEXTLINK Fibers, whether
or not due to the physical damage or severance of such fiber circuit; except
that no interruption of service caused in whole or in part by the negligent act
or omission or willful misconduct of NEXTLINK shall constitute an Outage.

          4.12 REPLACEMENT MAINTENANCE.  For any isolated incident wherein MFN
has failed to cure an Outage within the time frames stated in this Agreement or
on an Exhibit to this Agreement, or has failed to otherwise perform its
maintenance obligations as required under this Agreement, NEXTLINK may (after
notice to MFN, which may be oral if the circumstances so require) secure the
services of the contractor selected in advance by MFN for the purposes of
repairing and maintaining the NEXTLINK Fibers, the Long-Haul Innerduct or the
Additional Innerduct (as the case may be)  at such location at MFN's expense.

     ARTICLE V      PERMITS, ACCESS, AND REQUIRED RIGHTS-OF-WAY

          5.1  MFN represents and warrants that it has obtained or will obtain
all regulatory approvals, franchises, permits, orders, consents, and
rights-of-way, either by contract or through a franchise, and all other rights
necessary to be obtained by MFN to enable its provision of the NEXTLINK Fibers
and the grant of the IRU for the Long-Haul Innerduct and the Additional
Innerduct (all of which are herein collectively referred to as the
"Rights-of-Way").  If any provision in the Right-of-Way would in the reasonable
judgment of MFN, have an adverse impact on  NEXTLINK, MFN shall, on or before
the Acceptance Date for each segment of NEXTLINK Fibers, Long-Haul Innerduct or
Additional Innerduct, provide NEXTLINK with a copy or, in MFN's discretion, a
reasonably-detailed summary of all Rights-of-Way applicable to such segment of
the MFN System accepted. MFN shall exercise reasonable efforts to obtain any
necessary consent of any third party to the disclosure of such Rights-of-Way.
MFN shall use commercially reasonable efforts to cause such Rights-of-Way to
remain effective through the Term and any extensions (or to replace such
Right-of-Way with suitable replacement Right-of-Way).  MFN shall in no event be
required to extend any Right-of-Way other than the first ten-year renewal option
pursuant to MFN's agreement with Conrail dated February 24, 1997, as amended. 
In the event that any Rights-of-Way are discontinued and not replaced and the
loss of such Rights-of-Way adversely affects the use of the NEXTLINK Fibers, the
Long-Haul Innerduct, or the Additional Innerduct, MFN shall issue a rebate to
NEXTLINK.  The amount of the rebate shall be the pro rata 

<PAGE>

                                                                             15

portion of the payment allocable to the remainder of the term, in proportion to
the number of fiber miles (or route miles in the case of Long-Haul Innerduct or
Additional Innerduct).

     ARTICLE VI     RELOCATION OF THE MFN SYSTEM AND THE NEXTLINK FIBERS

          6.1  If MFN receives notice of any request, intent, or plan by any
third party, including, but not limited to, a governmental entity, to relocate
any segment of MFN's fiber network used in the provision of the NEXTLINK Fibers,
the Long-Haul Innerduct or the Additional Innerduct, MFN shall notify NEXTLINK
of such request, intent, or plan and shall consult with NEXTLINK regarding
proceedings and negotiations involving such proposed relocation and communicate
with NEXTLINK regarding the status of such proceedings and negotiations.  If MFN
is required by any such third party to relocate any segment of MFN's fiber
network used in providing the NEXTLINK Fibers, the Long-Haul Innerduct or the
Additional Innerduct, MFN shall give NEXTLINK at least sixty (60) days' (or such
lesser period of notice that MFN may have received) prior written notice of any
such relocation ("Relocation Notice").  Along with the Relocation Notice, MFN
shall provide an estimate of the cost of such relocation.  MFN shall relocate
the NEXTLINK Fibers, the Long-Haul Innerduct or the Additional Innerduct (as the
case may be), and, to the extent MFN is not reimbursed for the cost of such
relocation by a third party, governmental entity or otherwise, NEXTLINK shall
pay its Pro Rata share of the costs associated with the relocation of the
NEXTLINK Fibers, the Long-Haul Innerduct or the Additional Innerduct (as the
case may be); except, however, to the extent that the factors causing such
relocation are under MFN's control.  MFN shall use its reasonable best efforts

     C.1.  If Lessor shall purchase any item of capital equipment or make any
capital expenditure intended to result in savings or reductions in the Common
Area Maintenance Charges and which Lessor reasonably believes shall provide
Lessee with the benefit of a savings or reduction in such Common Area
Maintenance Charges based upon the advice of Lessor's consultants, then the
actual costs for same shall be included in the Common Area Maintenance Charges,
to the extent hereinafter set forth.  Lessor shall deliver to Lessee, promptly
following Lessee's request, a copy of any concluded studies conducted by Lessor
which show anticipated savings or reductions in such Common Area Maintenance
Charges as a result of any planned capital expenditure or purchase of capital
equipment.  The costs of capital equipment or capital expenditures shall be
included in the Common Area Maintenance Charges in the year in which the costs
are incurred and in any subsequent years, on a straight-line basis, to the
extent that such items are amortized over such period of time as reasonably can
be estimated at the time in which such savings or reductions in such Common Area
Maintenance Charges are expected to equal Lessor's costs for such capital
equipment or capital expenditure, with an interest factor equal to two percent
(2%) above the interest rate payable on United States Treasury securities having
a maturity comparable to the period of amortization at the time Lessor incurred
said costs.  If Lessor shall lease any such item of capital equipment designed
to result in savings or reductions in any Common Area Maintenance Charges, then
the rentals and other costs paid pursuant to such leasing shall be included in
such Common Area Maintenance Charges for the year in which they were incurred.

     2. If Lessor shall purchase any item of capital equipment or make any other
capital expenditure in order to comply with Legal Requirements, Insurance
Requirements or Environmental Laws (as those terms are hereinafter defined) or
reasonably necessary in order to benefit or increase the safety and security of
the Building, Property, or its tenants and/or invitees, then the costs for same
shall be included in Common Area Maintenance Charges for the year in which the
costs are incurred and subsequent years, on a straight-line basis, amortized
over the useful life of such items, with an interest factor equal to two percent
(2%) above the interest rate payable on United States Treasury securities having
a maturity comparable to the useful life of such items at the time Lessor
incurred said costs.  If Lessor shall lease any such item of capital equipment
to comply with Legal Requirements, Insurance Requirements, Environmental Laws or
to increase safety and security then, in such event, the rentals and other costs
paid pursuant to such leasing shall be included in Common Area Maintenance
Charges for the year in which they were incurred.

     3. If during all or part of any year, including calendar year 1998, (i)
less than ninety-five percent (95%) of the leasable space in the Building is
occupied by tenants or occupants or (ii) Lessor shall furnish any particular
item(s) of work or service (which would constitute a Common Area Maintenance
Charge hereunder) to less than ninety-five percent (95%) of the leasable
portions of the Building or to only a portion of the Property, due to the fact
that less than ninety-five percent (95%) of the leasable portions of the
Building are occupied, or because such item of work or service is not required
or desired by the tenant of such portion, or such tenant is itself obtaining and
providing such item of work or service, or for other reasons, then, for the
purposes 

                                     Page 4 of 40
<PAGE>
of computing the Additional Rent payable hereunder, the amount of Common Area
Maintenance Charges or the amount of the expenses attributable to such item as
the case may be, for such period shall be deemed to be increased by an amount
equal to the additional costs and expenses which would reasonably have been
incurred during such period had the Building been at least ninety-five percent
(95%) occupied or had Lessor furnished such item of work or services to such
other portions of the Building or the Property.

     D. Lessor shall have the absolute right, at all times during the Term and
any Renewal Term (as hereinafter defined) to increase, reduce, alter or
otherwise modify the way in which it uses, operates, repairs, or maintains the
Building and/or the Property and the cost thereof.  Nothing contained herein
shall require Lessor to incur or provide any particular service or charge in
connection with its use, operation, repair or maintenance of the Building and/or
Property, it being agreed and understood that the items described in Section
3.0l.B. are by way of illustration only and shall not obligate Lessor thereto,
except that Lessor shall maintain the Building and Property as a first class
office building located in Westchester County, New York.

     E. The term "Taxes" shall mean all such taxes, assessments, use and
occupancy taxes in respect of this Lease and any subleases made hereunder, water
and sewer charges, rates and rents, water and other meter charges and all such
other charges, taxes, levies and sums of every kind or nature whatsoever,
general and special, extraordinary as well as ordinary, whether or not now
within the contemplation of the parties, as shall or may during or in respect of
the Term (or any period prior to the Term for which Fixed Rent is payable) be
assessed, levied, charged or imposed upon or become a lien on the Property,
Building, or Demised Premises, or any part thereof, or anything appurtenant
thereto, or the sidewalks, streets or roadways in front of, adjacent to or
appurtenant to the Property, Building or Demised Premises (and which have a
basis related in any way to the Property, Building, or Demised Premises and/or
the use or manner of use thereof), or which, if imposed on Lessee or in respect
of the Property, Building or Demised Premises and if not paid by Lessee, would
be collectible from Lessor, or which have been so assessed, levied, charged or
imposed prior to the Term (but, in the last-mentioned case, only with respect to
a period falling within the Term); PROVIDED, HOWEVER, that, except if and to the
extent otherwise provided in the succeeding sentence, "Taxes" shall not mean
federal, state or local income taxes, franchise, excise, gift, transfer, capital
stock, estate, succession or inheritance taxes or penalties or interest for late
payment of any tax in respect of which Lessee shall have duly made payment of
Additional Rent as herein provided.  If, at any time during the Term, the
methods of taxation prevailing at the commencement of the Term shall be altered
so that, in lieu of or as a substitution in whole or in part for the taxes,
assessments, levies, impositions or charges now or hereafter levied, assessed or
imposed on real estate and the improvements thereon, shall be levied, assessed
or imposed any tax or other charge on or in respect of the Property, Building
and/or Demised Premises or the rents, income or gross receipts of Lessor
therefrom (including any county, town, municipal, state or federal levy), then
such tax or charge shall be deemed a Tax, but only to the extent that such Tax
would be payable if the Property, Building or Demised Premises, or the rent,
income or gross receipts received therefrom, were the only property of Lessor
subject to such Tax, and Lessee shall pay and discharge the same as herein
provided in respect of the payment of Taxes.

     F. The term "School Tax Base" shall mean the amount of Taxes as hereinabove
defined, imposed, levied, assessed and/or collected on the Property, for the
1997/1998 School Tax and "Town Tax Base" shall mean the amount of Taxes as
hereinabove defined, imposed, levied, assessed and/or collected on the Property
for the 1998 Town, County and State Tax.

     G. The term "School Tax Year" shall mean each period of twelve (12)
consecutive months commencing as of the first day of January of each such
period; and "Town Tax Year" shall mean each period of twelve (12) consecutive
months commencing as of the first day of January of each such period, in which
any part of the term of this Lease shall occur, or such other periods of twelve
(12) months as may be adopted as the fiscal year for real estate tax purposes.

     SECTION 3.02.A. Lessee shall pay to Lessor, as Additional Rent, during or
in respect of the period from the Commencement Date to the Expiration Date (both
dates inclusive) for each School Tax Year and Town Tax Year or portion thereof,
its proportionate share ("Lessee's Proportionate Share," as hereinafter defined)
of increases in Taxes which will be imposed, levied, assessed or collected on
the Property, and/or Building of which the Demised Premises are a part, for such
School Tax Year and/or Town Tax Year, as the case may be, over the respective
tax bases regardless of whether such increase results from a higher tax rate
and/or an increase in the assessed valuation of either the Property or Building
or any other tax.  Reasonable fees and expenses, if any, incurred in obtaining
any reduction in assessed valuation from the tentative 
                                     Page 5 of 40
<PAGE>

assessment to the final assessment shall also be considered an increase in Taxes
for the purpose of this provision.  Such payments shall be made by Lessee as
Additional Rent in equal monthly installments during the applicable tax year
together with the payment of Fixed Rent.  Copies of tax bills applicable to the
School Tax Base and the Town Tax Base, as the case may be, and to any such
applicable tax year shall be made available by Lessor for inspection by Lessee
during normal business hours.  In the event of any reduction in Taxes after
final assessment and with respect to which Lessee has paid its proportionate
share, any such reduction, less fees and expenses incurred to obtain such
reduction shall be refunded in proportionate amounts to Lessee.

     B. If Lessor obtains a reduction of either the School Tax Base or Town Tax
Base by final determination of legal proceedings or otherwise, then: (i) the
School Tax Base or Town Tax Base shall be correspondingly revised, (ii) all Tax
payments theretofore paid or payable hereunder shall be recomputed on the basis
of such reduction, (iii) Lessee shall pay to Lessor as Additional Rent, within
thirty (30) days after receipt of a bill therefor, any deficiency between the
amount of such Tax payments theretofore computed and the amount thereof due as a
result of such recomputations and (iv) all future Tax payments shall be computed
using the revised School Tax Base and Town Tax Base.

     SECTION 3.03.A. Lessee shall pay to Lessor, as Additional Rent, during or
in respect of the period from the Commencement Date to the Expiration Date (both
dates inclusive) for each calendar year or portion thereof, Lessee's
Proportionate Share of the increases in the Common Area Maintenance Charges over
the over the Base Common Area Maintenance Charges (as hereinafter defined). 
Such payments shall be made by Lessee as Additional Rent in equal monthly
installments during the applicable calendar year together with the payment of
Fixed Rent.

     B. The term "Base Common Area Maintenance Charges" shall mean the Common
Area Maintenance Charges in effect for the calendar year ending December 31,
1998.

     SECTION 3.04.A. At any time hereafter and from time to time, Lessor may
furnish to Lessee a Lessor's Statement setting forth (i) Lessor's actual Common
Area Maintenance Charges (or any one or more items thereof) and/or actual Taxes
for a period which shall have expired and/or (ii) Lessor's reasonable estimate
of Common Area Maintenance Charges and/or Taxes for a succeeding period.  Within
thirty (30) days next following rendition of each such Lessor's Statement,
Lessee shall pay to Lessor the entire amount, if any, shown on such Lessor's
Statement as being due with respect to any period which shall have expired.  In
addition, Lessee shall pay to Lessor, on the first day of each month following
rendition of each such Lessor's Statement, on account of the estimated
Additional Rent thereafter payable, a proportionate sum of the total Additional
Rent shown upon such Lessor's Statement as being Lessor's reasonable estimate
for a succeeding period on an annual basis (it being agreed that Lessor's
estimate shall in any event be deemed reasonable if it is based on actual Common
Area Maintenance Charges (or any one or more items thereto and/or actual Taxes
for a period which shall have expired immediately prior thereto, so that one
month prior to the end of such period, Lessee's Proportionate Share of the
increase shall be paid in full, and Lessee shall continue to pay Additional Rent
on such basis until receipt of a subsequent Lessor's Statement.  Such Additional
Rent shall be due and payable at the same time as each monthly installment of
Fixed Rent.

     B. A reconciliation shall be made upon each Lessor's Statement as follows:
Lessee shall be debited with any Common Area Maintenance Charges and/or Taxes
payable as shown on such Lessor's Statement, and credited with the aggregate of
the total amount, if any, paid by Lessee in accordance with the provisions of
the preceding paragraph on account of the estimated Additional Rent, for the
period or item in question, and, within thirty (30) days next following
rendition of such Lessor's Statement, Lessee shall pay Lessor the amount of any
net debit balance shown thereon or Lessor shall apply against the next ensuing
installments of Fixed Rent the net credit balance shown thereon.

     C. Without limiting the preceding provisions of Section 3.04, it is
understood that Lessor shall furnish a Lessor's Statement, for each calendar
year falling wholly or partially within the Term.

     SECTION 3.05.A. Lessor's failure to render Lessor's Statements with respect
to any period shall not prejudice Lessor's fight to render a Lessor's Statement
with respect to that or any subsequent period.  The obligations of Lessor and
Lessee under the provisions of this Article with respect to Additional Rent
shall survive the expiration or any sooner termination of the Term.

     B. Each Lessor's Statement shall be conclusive and binding upon Lessee
unless within thirty (30) days after receipt of such Lessor's Statement, Lessee
shall notify Lessor that it disputes 

                                     Page 6 of 40
<PAGE>
the reasonableness or correctness of Lessor's Statement, specifying the respects
in which Lessor's Statement is claimed to be unreasonable or incorrect. Pending
the determination of such dispute by agreement or otherwise, Lessee shall pay
Additional Rent in accordance with the applicable Lessor's Statement, and such
payment will be without prejudice to Lessee's position.  If the dispute shall be
finally determined in Lessee's favor by a court of competent jurisdiction,
Lessor shall forthwith pay Lessee the amount of Lessee's overpayment of
Additional Rent resulting from compliance with Lessor's Statement.  Lessor, upon
request of Lessee, shall either make available to Lessee such documentation as
may be in Lessor's possession to support a particular Common Area Maintenance
Charge or permit Lessee to examine relevant portions of Lessor's books and
records.

     SECTION 3.06. Lessee shall pay and discharge, or cause to be paid and
discharged, the following items, regardless of to whom or how incurred, all
taxes and assessments, if any, which shall or may during the Term be charged,
levied, assessed or imposed upon, or become a lien upon, the personal property
of Lessee used in the operation of the Demised Premises and which if not paid by
Lessee, would be collectible from Lessor.

the proper and lawful conduct of Lessee's business in the Demised Premises or
any part thereof, then Lessee, at its sole cost and expense, shall duly procure
and thereafter maintain such license or permit and submit the same to inspection
by Lessor.  Lessee shall, at all times, comply with the terms and conditions of
each such license or permit, but in no event shall failure to procure and
maintain same by Lessee affect Lessee's obligations hereunder.  Lessee shall not
use or occupy the Demised Premises, or suffer or permit anyone to use or occupy
the Demised Premises, in violation of any certificate of occupancy issued for

necessary or otherwise required by law in accordance with the specifications

excess of ordinary lavatory and drinking purposes as shown on said meter as
Additional Rent as and when bills are rendered; (d) air conditioning and/or

the following conditions: (i) the occupancy does not exceed one (1) person for
each 150 square feet of area; (ii) the total connected electrical load does not
exceed 5 watts per square foot of installed ceiling area for all purposes,
including lighting and power; and (iii) proper use of window blinds to control
sunload.  The system shall provide fresh air as per code requirements.  If due
to use of the Demised Premises in a number exceeding the aforementioned
occupancy and electrical load criteria, or due to rearrangement of partitioning
after the initial preparation of the Demised Premises, interference with normal
operation of the air conditioning in the Demised Premises results, necessitating
changes in the air conditioning system servicing the Demised Premises, such
changes shall be made by Lessor upon written notice to Lessee and at Lessee's
sole cost and expense.  Lessee agrees to keep all windows closed, and to lower
and close window coverings when necessary because of the sun's position whenever
the said air conditioning system is in operation, and Lessee agrees at all times
to cooperate fully with Lessor and to abide by all the regulations and
requirements which Lessor may prescribe for the proper functioning and
protection of the said air conditioning system.  Lessor, throughout the Term,
shall have free and unrestricted access to any and all air conditioning
facilities in the Demised Premises.

     C. Except as otherwise specifically provided for in this Lease, Lessor
represents that Lessee shall have access (by elevator) to the Demised Premises
Twenty-Four (24) hours a day, Seven (7) days a week.

     D. Lessor agrees that Lessee shall have the right to use the existing
supplemental air conditioning units located in the Demised Premises, which shall
be in working order on the Commencement Date.  During the Term hereof and any
Renewal Term, Lessor shall furnish to Lessee condenser water ("Condenser Water")
serving not more than Five (5) tons of rated cooling capacity for use in
connection with the Supplemental Units serving the Demised Premises.  Lessee
agrees to pay Lessor for all Condenser Water used in connection with the
Supplemental Units at the rate of One Hundred and Twenty-Five and 00/100
($125.00) Dollars per month, per rated ton of connected load (the "Condenser
Water Charge"), PROVIDED, HOWEVER, that in no 

                                     Page 9 of 40
<PAGE>

event shall Lessor ever be obligated to provide Lessee with more than Five (5)
tons per hour of Condenser Water for use in connection with the Supplemental
Units.

     SECTION 6.02. During the Term hereof and any Renewal Term, Lessor shall
furnish to Lessee cleaning services for the Demised Premises in accordance with
the Cleaning Specifications annexed hereto as EXHIBIT "D."

     SECTION 6.03.A. If Lessee uses the Demised Premises outside Normal Working
Hours, Lessee agrees to pay to Lessor an overtime charge to cover Lessor's
actual expenses for electricity for lighting and normal Building Equipment (as
hereinafter defined) and other incidental equipment, extra building maintenance,
building employee overtime, furnishing water for lavatories, air cooling, heat,
ventilation, wear and tear, etc. caused by Lessee's overtime use ("Overtime
Services").

     B.1. Lessor shall furnish such Overtime Services to Lessee as may be
required provided that (i) Lessee pays to Lessor as Additional Rent special
overtime charges (the "Overtime Charges") therefor, which is presently at the
rate of One Hundred and Seventy-Five and 00/100 ($175.00) Dollars per hour,
along with Lessee's next monthly installment of Fixed Rent if such service shall
have been finished to Lessee prior to the fifteenth (15th) day of the month or
along with the subsequent monthly installment of Fixed Rent if such service
shall have been furnished to Lessee after the fifteenth (15th) day of the month,
(ii) that Lessee's request shall be received by Lessor by not later than 2:00
P.M. on the day for which such required after hours service is requested (and by
not later than 2:00 P.M. on the day preceding any requested before-hours
service), (iii) that Lessor shall not be required to furnish such Overtime
Services to Lessee for more than twenty (20) hours in any one (1) week, and (iv)
the Building HVAC system is not then producing chilled water for future HVAC
use.  Notwithstanding anything contained to the contrary in this Article 6,
Lessee shall not be required to pay Overtime Charges for intermittent use of the
Demised Premises outside Normal Working Hours, provided that such use shall not
be on a scale and of a frequency so as to constitute the regular operation of
Lessee's business outside Normal Working Hours.  In no event, however, shall
Lessor be obligated to supply heating or air conditioning outside of Normal
Working Hours unless Lessee shall request and pay for the same as provided in
this Article 6.

     2. Lessee agrees that the Overtime Charges and Condenser Water Charge may,
from time to time, be increased by Lessor, with not less than thirty (30) days
prior written notice to Lessee, if the rates at which Lessor purchases
electrical energy from the public utility corporation supplying electrical
current to the Building of which the Demised Premises are a part or shall be
increased, or the cost of supplying Condenser Water shall be increased, or any
tax is imposed upon Lessor's receipt from the sale or resale of electrical
energy or Condenser Water by any Federal, State or Municipal Authority, or any
charges incurred or taxes payable by Lessor in connection therewith shall be
increased.  The Overtime Charges and Condenser Water Charge shall be increased
by an amount equal to the product of the respective hourly rate times the
percentage increase in the rates at which Lessor purchases electrical energy
from the public utility corporation as aforesaid, or the percentage increase in
the cost of producing Condenser Water, as the case may be.

     SECTION 6.04.A. Lessee acknowledges and agrees that Lessor shall furnish
electrical current to Lessee for lighting, electrical appliances and/or office
equipment in the Demised Premises, including electrical current for the
Supplemental Units ("Electric Service") based on the method of including the use
thereof within the Fixed Rent and, accordingly, Lessee agrees that the Fixed
Rent provided for in Article 2 of this Lease has been increased to compensate
Lessor for supplying Electric Service on the basis of Two and 25/100 dollars
($2.25) per square foot per annum for each square foot contained in the Demised
Premises (hereinafter referred to as the "Base Charge") payable in equal monthly
installments commencing on the Commencement Date.  By the execution of this
Lease, Lessee acknowledges and agrees that the Base Charge shall not be
contestable by Lessee at a future date and shall only be increased by Lessor at
a future date in accordance with this Section.  Lessor will furnish electricity
to Lessee through presently installed electrical facilities, which Lessor
represents to be at least five (5) watts of connected load per square foot of
installed ceiling area for all lighting and power purposes, for Lessee's
reasonable use.

     B.1. Lessee shall make no substantial alterations or additions to the
initial lighting, electrical appliances or office equipment without first
obtaining written consent from Lessor (which consent shall not be unreasonably
withheld or delayed) in each instance.  Lessor warrants that the electrical
facilities servicing the Demised Premises is in good working order and can
accommodate a normal office installation with associated office machinery and
equipment.  

                                    Page 10 of 40
<PAGE>

Lessee agrees that at all times its use of Electric Service shall not exceed the
capacity or overload any of the central and appurtenant installations for
Electric Service including, but not limited to all wires, feeders, risers,
electrical boxes, switches, outlets, connections, and cables located in the
Property, Building, or Demised Premises or any other mechanical equipment spaces
located therein.  Lessee's use of Electric Service shall not interfere with the
use thereof by other occupants of the Property, or Building and shall be of such
a nature, as determined by Lessor in its reasonable judgment and discretion, so
as not cause permanent damage or injury to the Demised Premises or the Building
of which the Demised Premises are a part, or cause or create a dangerous or
hazardous condition or entail excessive or unreasonable alterations, repairs or
expense, or interfere with or disturb other tenants or occupants.

     2. If at any time prior to or during the Term or any Renewal Term of this
Lease, subject to the restrictions contained elsewhere in this Lease: (i) Lessee
installs substantial additional or substituted lighting, electrical appliances,
office equipment or otherwise increases its use of Electric Service in excess of
five (5) watts of connected load per square foot of installed ceiling area for
all purposes, and/or; (ii) subject to the provisions of Article 8 of this Lease,
electrical feeders, risers, wiring or other electrical facilities serving the
Demised Premises shall be installed by Lessor, Lessee or others, on behalf of
Lessee or any person claiming through or under Lessee in addition to the
feeders, risers, wiring or other electrical facilities necessary to serve the
lighting fixtures, electrical appliances, office equipment and electrical
receptacles initially located in the Demised Premises; then the Fixed Rent shall
be increased by an amount determined by the electrical engineer selected by
Lessor who shall certify the amount of the Additional Rent to be increased in
writing to Lessor and Lessee.  Following any such determination and
certification by the electrical engineer, this Lease shall automatically be
modified by increasing the Additional Rent by an amount equal to (i) the product
of the Base Charge times the percentage increase in Lessee's use of electrical
current over that for Lessee's initially installed lighting, electrical
appliances and office equipment and/or (ii) the product of the Base Charge times
the percentage increase in the potential additional electrical energy made
available to Lessee annually based upon the estimated capacity of such
additional electrical feeders, risers, wiring or other electrical facilities, as
the case may be.  As evidence of such modification, such electrical engineer's
certification shall be delivered by Lessor to Lessee and also appended hereto. 
Any such increase shall be effective as of the date of the first use by Lessee
of such additional service and retroactive to such date if necessary.  In
addition, Lessee shall pay to Lessor, as Additional Rent, within ten (10) days
of the date of a notice therefor from Lessor, the total actual Cost (as
hereinafter defined) to Lessor of the additional electrical feeders, risers,
wiring, or other electrical facilities serving the Demised Premises.

     C. If, at any time or times after the date of this Lease, the rates at
which Lessor purchases electrical energy from the public utility corporation
supplying electrical current to the Building of which the Demised Premises are a
part shall be increased, or any tax is imposed upon Lessor's receipt from the
sale or resale of electrical energy or gas or telephone service to Lessee by any
Federal, State or Municipal Authority, or any charges incurred or taxes payable
by Lessor in connection therewith shall be increased, the Additional Rent shall
be increased by an amount equal to the product of the Base Charge times the
percentage increase in the rates at which Lessor purchases electrical energy
from the public utility corporation as aforesaid, over those rates in effect on
the date of the calculation of the Base Charge.  Following any such rate
increase or other charge, this Lease shall automatically be modified by
increasing the Additional Rent for the remainder of the term hereof in
accordance with this Subsection and, as evidence of such modification,
documentation of such rate increase or other charge shall be delivered by Lessor
to Lessee and also appended hereto.  Any such increase in the Additional Rent
shall be effective as of the date of any such increase in cost or other charge
to Lessor and shall be retroactive to such date if necessary.

     D. Notwithstanding anything contained to the contrary in this Article 6,
Lessor shall have the right, at its option, to conduct a survey of the Demised
Premises by an electrical engineer of Lessor's choosing at any time during the
term of this Lease in order to determine Lessee's actual use of electrical
current therein.  In the event that Lessor's survey provided for in the
preceding sentence shall indicate that Lessee's use of electrical current
exceeds five (5) watts of connected load per square foot of installed ceiling
area for all purposes, Lessee, upon receipt of notice from Lessor, shall pay to
Lessor an increase in Fixed Rent equal to an amount determined by multiplying
the Base Charge times the percentage increase in Lessee's use of electrical
current over five (5) watts of connected load per square foot of installed
ceiling area for all purposes.  Any such increase shall be payable in accordance
with the terms of this Article 6 and shall be effective as of the date of
Lessee's first increased use of electrical current and shall be retroactive to
such date, if necessary.

                                    Page 11 of 40
<PAGE>
     SECTION 6.05. Except as otherwise specifically provided for in this Lease,
Lessor reserves the right to temporarily stop, interrupt and/or suspend Utility
Service, and/or Electric Service when necessary by reason of accident or for
repairs, alterations, replacements or improvements necessary or desirable in the
judgement of Lessor for as long as may be reasonably required by reason thereof.
The repairs, alterations, replacements or improvements shall be done with a
minimum of inconvenience to Lessee and Lessor shall pursue same with due
diligence.

     SECTION 6.06. Except to the extent caused by the negligent or wilful acts
or on omissions of Lessor, its employees, agents or contractors, Lessor shall in
no way be liable for any loss, damage, or expense which Lessee may incur as a
result of the change, at any time, of the character or quality of Electric
Service, or Utility Service or any failure of or defect in Electric Service, or
Utility Service by reason of any public or private utility company then
supplying such service to the Property, Building or the Demised Premises and
Lessee agrees to hold the Lessor harmless and to indemnify it from and against
any loss, liability or damage in connection therewith.  This indemnity shall
survive the expiration or other termination of this Lease.

                          ARTICLE 7 - REPAIR AND MAINTENANCE

     SECTION 7.01.A. Subject to the provisions of Section 7.02 hereof, Lessee
shall, during the Term of this Lease and any Renewal Term, at Lessee's sole cost
and expense, take good care of, maintain and make all repairs (other than
structural) in the Demised Premises, and the fixtures and equipment therein and
appurtenances thereto, including but not limited to, the Supplemental Units,
internal doors and entrances, door checks, internal signs, floor covering,
interior walls, columns and partitions; and lighting, heating, hot water,
plumbing and sewerage facilities, sprinkler system and sprinkler heads located
within the Demised Premises and serve only the Demised Premises.

     B. If Lessee refuses or neglects to maintain or make repairs or otherwise
fails to perform any of Lessee's repair or maintenance obligations hereunder,
Lessor shall have the right, but shall not be obligated, to make such repairs or
perform on behalf of and for the account of Lessee.  All sums so paid by Lessor
in connection with the payment or performance by it or any of the obligations of
Lessee hereunder and all actual and reasonable costs, expenses and disbursements
paid in connection therewith or enforcing or endeavoring to enforce any right
under or in connection with this Lease, or pursuant to law, together with
interest thereon at the minimum legal rate from the respective dates of the
making of such payment, shall constitute Additional Rent payable by Lessee under
this Lease and shall be paid by Lessee to Lessor upon demand by Lessor.  The
provisions of this Section shall survive the expiration or other termination of
this Lease.

     SECTION 7.02.A. Lessor shall not be required to make any repairs or
improvements of any kind upon the Demised Premises except for necessary
structural repairs to the Building or for damage caused by a casualty or
Lessor's negligent or wilful acts or omissions, excluding Lessee's property. 
Lessor shall during the Term of this Lease and any Renewal Term, maintain and
repair all common areas and other facilities in or about the Property and/or the
Building, exclusive of doors, door frames, door checks, windows and window
frames.  Lessor shall have the right to construct, maintain and operate lighting
and other facilities on all said areas and improvements; to police the same; to
change the area, level, location and arrangement of parking areas and other
facilities; to build multistory parking facilities; to restrict parking by
Lessees, their officers, directors, agents and employees, to enforce parking
charges (by operation of meters and otherwise to the extent required by law);
and to close all or any portion of said areas or facilities to such extent as
may be legally sufficient to prevent a dedication thereof or the accrual of any
right to any person or the public therein; to close temporarily all or any
portion of the parking areas or facilities to discourage non-visitor parking. 
Lessor shall operate and maintain the common areas in such manner as Lessor in
its discretion shall determine, and Lessor shall have full right and authority
to employ and discharge all personnel with respect thereto.  If Lessor shall
designate an employee or lessee parking area or areas, Lessee and its employees
shall use only such areas for parking and Lessee shall cooperate fully with
Lessor in enforcing this covenant.

     B. In the event that Lessor is unable or fails to provide Critical Services
(as hereinafter defined) which it is obligated to provide under this Lease
solely as a result of Lessor's negligence, wilful acts or omissions, and the
loss of such services causes all or part of the Demised Premises to become
unusable or access to the Demised Premises is not reasonably available for more
than five (5) consecutive business days, or if such condition is caused by any
other reason other than as provided for herein and such condition continues for
thirty (30) 
                                    Page 12 of 40
<PAGE>

consecutive days, and the Demised Premises are in fact not used for the purposes
for which they were leased, during such period, then in such event, Lessee shall
be entitled to a pro rata abatement of Rent commencing with the sixth (6th)
consecutive business day, or the thirty-first (31st) consecutive day that same
are unusable, as the case may be; PROVIDED, HOWEVER, that Lessee shall not be
entitled to any abatement of Rent if such unusability is (a) caused by the
negligence or wilful act or omission of Lessee or any of Lessee's servants,
employees, agents, or licensees; or (b) where such condition arises in
connection with work performed by Lessor at the request of Lessee to make a
decoration, alteration, improvement or addition; or (c) where the repair in

withheld or delayed.

     SECTION 7.04. Lessor shall not be required to make any repairs or
replacements to the common areas occasioned by the act or negligence of Lessee,
its agents, employees, invitees, customers, licensees, or contractors, except to
the extent that Lessor is reimbursed therefor under any policy of insurance

     SECTION 8.01. Lessor shall have no obligation whatsoever to perform any
build-out or similar work to Demised Premises, and Lessee agrees to accept same
in "AS IS" physical order and condition on the Commencement Date and without any
representation or warranty, express or implied, in fact or by law, by Lessor,
and without recourse to Lessor, as to title thereto, the nature, condition or
usability thereof or as to the use or occupancy which may be made thereof. 
Notwithstanding the foregoing, Lessor agrees to perform the work set forth on
the plans and specifications annexed hereto as EXHIBIT "E" and made a part
hereof (the "Work").  Lessor agrees to perform, at its sole cost and expense,
that portion of the Work more particularly set forth on EXHIBIT "F" annexed

operating fixtures and equipment, plumbing, lighting and other fixtures and
equipment, furniture, furnishings, floor covering, and any and all other items
necessary for the proper operation of Lessee's business ("Lessee's Work").  All
equipment permanently affixed to the Demised Premises by Lessee shall not be
subject to liens, conditional sales contracts, security agreements or chattel
mortgages.  Nothing contained herein shall prohibit Lessee from purchasing
display and other moveable equipment which may be subject to liens, conditional
sales contracts, security agreements or chattel mortgages ("Lessee's Trade
Fixtures").  Lessee shall complete or cause to be completed all of Lessee's Work
required on Lessee's part to be performed in and at the Demised Premises under
this Lease pursuant to Lessor's STANDARD REQUIREMENTS FOR ALTERATIONS TO BE
PERFORMED BY LESSEES' annexed hereto as EXHIBIT "G," as may be amended from time
to time.

     SECTION 8.03. Other than as specifically provided for in Section 8.02
hereof, Lessee shall not do any construction, work or alterations to the Demised
Premises, nor shall Lessee install any items other than Lessee's Trade Fixtures

     SECTION 9.01. Lessor represents that the Demised Premises, the Building and
Property and all of Lessor's Work will comply with all Legal Requirements,
Environmental Laws and Insurance Requirements as of the Commencement Date.

     SECTION 9.02. Throughout the Term of this Lease and all Renewal Terms, if
any, Lessee shall promptly comply with all Legal Requirements, Environmental
Laws and Insurance Requirements whether or not such compliance involves
structural repairs or changes or be required on account of any particular use to
which the Demised Premises, or any part, may be put, and whether or not any such
Legal Requirements, Environmental Laws, or Insurance Requirements be of a kind
not now within the contemplation of the parties hereto.  Compliance by Lessee
with Legal Requirements, Environmental Laws, and Insurance Requirements shall be
at Lessee's sole cost and expense.  Lessee shall not contest the application or
validity of any such Legal Requirements, Environmental Laws, or Insurance
Requirements without the prior written consent of Lessor in each such instance. 
Any repair or change required under this Section shall be deemed a repair for
the purposes of Article 7.  With respect to actions necessary to comply with
Legal Requirements, Insurance Requirements and Environmental Laws which, due to
their nature, can only be taken by Lessor, Lessor, at Lessee's expense, will
cooperate with Lessee in facilitating such compliance.

annoyance, disturbance or loss of business to Lessee or any sublessee by reason
of making any repairs or the performance of any work, or on account of bringing
materials, tools, supplies and equipment into or through the Demised Premises
during the course thereof and the obligations of Lessee under this Lease shall
not be affected thereby.  The rights provided in this Article shall be exercised
so as to minimize interference with the use and occupancy of the Demised
Premises by Lessee.  Nothing contained in this Article shall impose, or shall be
construed to impose on Lessor any obligation to maintain the systems referred to
in this Article or the Demised Premises or anything appurtenant thereto, or to
make repairs or alterations thereof or thereto, or to create any liability for
any failure to do so.

including overtime cost incurred by Lessor in the event that repairs,
alterations, decorating or other work in the Demised Premises are made or done
after ordinary business hours at Lessee's request, (e) to immediately enter and

     further insure, at Lessor's request, against any other peril generally
     insured against by a business of Lessee's type.

     B. Said insurance is to be written in form and substance reasonably
satisfactory to Lessor by an insurance company, licensed to do business in the
State of New York, which shall be rated by Best's Insurance Rating Service with
at least a rating equal to A:XII.  Lessee shall procure, maintain and place such
insurance and pay all premiums and charges therefor and upon failure to do so
Lessor may, but shall not be obligated to, procure, maintain and place such
insurance or make such payments, and in such event Lessee agrees to pay the
amount thereof plus interest at the maximum legal rate, to Lessor on demand as
Additional Rent.  If Lessee has other locations that it owns or leases, said
policy shall include an aggregate per location endorsement.  Lessee shall cause
to be included in all such insurance policies (i) a provision to the effect that
the same will not be canceled or modified except upon not less than thirty (30)
days' prior written notice to the Lessor, and (ii) a provision to the effect
that the naming of any person other than Lessee as an insured shall not obligate
such person to pay any premium.  Each such Lessee's fire (casualty) insurance
policy shall contain an agreement by the insurer that the act or omission of one
insured will not invalidate the policy as to any other insured.  Not less than
ten (10) days prior to the Commencement Date the original insurance policies or
appropriate certificates and paid receipts therefor (together with a photocopy
of the policy, if Lessor shall so request), shall be deposited with Lessor.  Any
renewals or endorsements thereto shall also be deposited with Lessor, not less
than ten (10) days prior to the expiration date of the policy being renewed, 

                                    Page 15 of 40
<PAGE>
replaced or endorsed, to the end that said insurance shall be in full force and
effect at all times during the Term.

     SECTION 11.02. Lessee agrees to use reasonable efforts to include in each
of its insurance policies (insuring the Demised Premises and Lessor's property
therein, against loss occasioned by fire or other casualty) a waiver of the
insurer's right of subrogation against the Lessor, or if such waiver should be
unobtainable or unenforceable, (a) an express agreement that such policy shall
not be invalidated if the insured waives or has waived before the casualty the
right of recovery against any party responsible for a casualty covered by the
policy, or (b) any other form of permission for the release of the other party,
or (c) the inclusion of the Lessor as an additional insured, as its interests
may appear.  Lessee, upon request from Lessor from time to time, will furnish
evidence of the nature of the insurance arrangements made concerning the subject
matter of this Section.

     SECTION 11.03. As long as both parties' fire (casualty) insurance policies
then in force include the waiver of subrogation or agreement or permission to
release liability referred to in Section 11.02 or name the other party as an
additional insured, each party hereby waives (and agrees to cause any other
permitted occupants of the Demised Premises to execute and deliver to the other
party written instruments waiving) any right of recovery against the other
party, the holder of the Mortgage, or Superior Lease, and any servants,
employees, agents or contractors of the other party, or of any such Lessor's or
holder, or of any such other tenants or occupants, for any loss occasioned by
fire or other casualty, that is an insured risk under Lessee's fire (casualty)
insurance policies.  In the event that at any time either party's fire
(casualty) insurance carriers shall not include such or similar provisions in
the other party's fire (casualty) insurance policies, the waivers set forth in
the foregoing sentence shall be deemed of no further force and effect.  During
any period when either party fails to maintain such fire (casualty) insurance,
for the purposes of the first sentence of this Section there shall be deemed to
be in effect such fire (casualty) insurance meeting the requirements of such
sentence.

     SECTION 11.04. Nothing contained in this Lease shall (i) relieve Lessee of
any liability to Lessor or to its insurance carriers which Lessee may have under
law or the provisions of this Lease in connection with any damage to the Demised
Premises by fire or other casualty; (ii) impose upon Lessor any duty to procure
or maintain any kinds of insurance or any particular amounts or limits of any
such kinds of insurance.

     SECTION 11.05. Lessor shall insure the Building with all risk insurance
coverage in such amounts so as to avoid co-insurance and Lessor agrees that such
policies shall contain a waiver of subrogation in favor of Lessee.

                          ARTICLE 12 - DAMAGE OR DESTRUCTION

     SECTION 12.01. If the Demised Premises or any part thereof shall be damaged
by fire or other casualty, Lessee shall give prompt notice thereof to Lessor and
Lessor shall proceed (subject to the provisions of this Article) with reasonable
diligence to repair or cause to be repaired such damage.  Except as provided in
Section 12.05, the Fixed Rent shall be abated proportionately to the extent that
the Demised Premises shall have been rendered Untenantable (as hereinafter
defined), such abatement to be from the date of such damage or destruction to
the date the Demised Premises shall no longer be Untenantable.

     SECTION 12.02. If the Demised Premises shall be totally damaged or the
whole of the Demised Premises shall be rendered Untenantable by fire or other
casualty, and Lessor has not terminated this Lease pursuant to Section 12.03 and
Lessor has not completed the making of the required repairs and restored and
rebuilt the Demised Premises and/or access thereto within one (1) year from the
date of such damage or destruction to the level of demising walls only, and such
additional time after such date, as shall equal the aggregate period Lessor may
have been delayed in doing so by Unavoidable Delays or adjustment of insurance,
Lessee may serve notice on Lessor of its intention to terminate this Lease and
if within thirty (30) days thereafter, Lessor shall not have substantially
completed the making of the required repairs and restored and rebuilt the
Demised Premises to the level of demising walls, then in such events, this Lease
shall terminate on the expiration of such thirty (30) day period as if such
termination date were the Expiration Date, and the Fixed Rent and Additional
Rent shall be apportioned as of such date of sooner termination and any prepaid
portion of Fixed Rent and Additional Rent for any period after such date shall
be refunded by Lessor to Lessee.

     SECTION 12.03.A. If the Demised Premises shall be totally damaged or the
whole of the Demised Premises shall be rendered Untenantable by fire or other
casualty or if the Demised 
                                    Page 16 of 40
<PAGE>

Premises shall be so damaged by fire or other casualty that substantial
alteration or reconstruction shall, in Lessor's reasonable opinion, be required,
then and in such events Lessor may, at its option, terminate this Lease and the
Term and estate hereby granted by giving Lessee not less than thirty (30) days,
nor more than sixty (60) days, notice of such termination, within ninety (90)
days after the date of such damage.  In the event that such notice of
termination shall be given, this Lease and the Term and estate hereby granted
shall terminate as of the date provided in such notice of termination (whether
or not the Term shall have commenced) with the same effect as if that were the
Expiration Date, and the Fixed Rent and Additional Rent shall be apportioned as
of such date of sooner termination, mid any prepaid portion of Fixed Rent and
Additional Rent for any period after such date shall be refunded by Lessor to
Lessee.

     B. If the Demised Premises shall be totally damaged or the whole or
substantially all of the Demised Premises shall be rendered untenantable by fire
or other casualty, and Lessor has not terminated this Lease as provided in
Section 12.03.A., Lessor shall notify Lessee, within ninety (90) days after such
fire or other casualty, as to the estimated period of time necessary to complete
the required repairs and restore and rebuild the Demised Premises to the level
of demising walls.  If such Lessor's estimate exceeds one (1) year, from the
date of such notice, or if Lessor falls to deliver such notice, then in such
events, Lessee may serve on Lessor, within thirty (30) days of its receipt of
Lessor's notice, or the expiration of the ninety (90) days after such fire or
other casualty, as the case may be (time being of the essence with respect
thereto), notice of its intention to terminate this Lease on a date which shall
be not more than thirty (30) days from the date of Lessee's notice.  If Lessee
gives notice of its intention to cancel this Lease as provided herein, then in
such event, this Lease shall terminate on the expiration of such thirty (30) day
period as if such termination date were the Expiration Date, and the Fixed Rent
and Additional Rent shall be apportioned as of such date of sooner termination
and any prepaid portion of Fixed Rent and Additional Rent for any period after
such date shall be refunded by Lessor to Lessee.  Lessee's failure to notify
Lessor within the thirty (30) day period shall be deemed a waiver of the right
to terminate this Lease.

     SECTION 12.04. Lessor shall not be liable for any inconvenience or
annoyance to Lessee or injury to the business of Lessee resulting in any way
from such damage by fire or other casualty or the repair thereof.

     SECTION 12.05. Lessee shall restore all improvements made by Lessee to the
Demised Premises, at Lessee's sole cost and expense.  Nothing herein contained
shall relieve Lessee from any liability to the Lessor or to its insurers in
connection with any damage to the Property, Building or Demised Premises by fire
or other casualty if Lessee shall be legally liable in such respect. 
Notwithstanding any of the foregoing provisions of this Article, if by reason of
some action or inaction on the part of Lessee or any of its employees, agents,
officers, directors or contractors, Lessor or the holder of the Mortgage or
Superior Lease shall be unable to collect all of the insurance proceeds
(including rent insurance proceeds) applicable to damage or destruction of the
Demised Premises by fire or other cause, then, without prejudice to any other
remedy which may be available against Lessee, the abatement of Fixed Rent
provided for in this Article shall not be effective to the extent of the
uncollected insurance proceeds.

     SECTION 12.06. This Lease shall be considered an express agreement to the
contrary pursuant to New York REAL PROPERTY LAW Section 227 governing any case
of damage to or destruction of the Demised Premises or any part thereof by fire
or other casualty, and any law providing for such a contingency in the absence
of such express agreement, now or hereafter enacted, shall have no application
in such case to the extent inconsistent with this Lease.

     SECTION 12.07. Lessee shall, at its own cost and expense, remove all of
Lessee's property from the Demised Premises as Lessor shall require in order to
repair and restore the Demised Premises and Lessor shall not be obligated to
commence repairs or restoration of the Demised Premises until such property has
been removed by Lessee from the damaged portion of the Demised Premises.  Should
Lessee neglect, fail, or refuse to remove its aforesaid property within thirty
(30) days after such damage or destruction, the provisions for abatement of
Fixed Rent contained herein shall be suspended and of no force and effect
whatsoever until Lessee has completed such removal.  In no event shall the
Lessor be required to repair or replace Lessee's merchandise, trade fixtures,
furniture, furnishings, inventory and equipment.

                   ARTICLE 13 - CURING DEFAULT'S; FEES AND EXPENSES

     SECTION 13.01. If Lessee shall default in the full and prompt performance
of any covenant contained herein and to be performed on Lessee's part, Lessor,
after notice to Lessee in accordance with provisions of this Lease (except that
a lesser notice appropriate to the 

                                    Page 17 of 40
<PAGE>

circumstances shall be required in case of an emergency), without being under
any obligation to do so and without thereby waiving such default may perform
such covenant for the account and at the expense of Lessee and may enter upon
the Demised Premises for any such purpose and take all action thereon as may be
necessary therefor.  All reasonable sums so paid by Lessor in connection with
the payment or performance by it of any of the obligations of Lessee hereunder
and all actual and reasonable costs, expenses and disbursements paid in
connection therewith or enforcing or endeavoring to enforce any right under or
in connection with this Lease, or pursuant to law, together with interest
thereon at the maximum legal rate from the respective dates of the making of
each such payment, shall constitute Additional Rent payable by Lessee under this
Lease and shall be paid by Lessee to Lessor upon demand by Lessor.  The
provisions of this Section shall survive the expiration or other termination of
this Lease.

                           ARTICLE 14 - DEFAULT PROVISIONS

     SECTION 14.01.A. If any one or more of the following events shall happen
and shall not have been cured within any applicable grace period herein
provided:

          (1) if default shall be made in the due and punctual payment of Fixed
     Rent or Additional Rent payable by Lessee under this Lease when and as the
     same shall become due and payable, and such default shall continue for a
     period of five (5) days after written notice thereof from Lessor to Lessee
     (provided that no such notice shall be required if, during the period of
     one (1) year immediately preceding the date of default, there shall have
     been two (2) or more defaults in the due and punctual payment of Fixed Rent
     or Additional Rent payable by Lessee under this Lease when and as the same
     shall have been due and payable); or

          (2) if default shall be made by Lessee in performance of, or
     compliance with, any of the covenants, agreements or conditions contained
     in this Lease and either (i) in the case of a default or a contingency
     which can with due diligence be cured within thirty (30) days, such default
     shall continue for a period of thirty (30) days after written notice
     thereof from Lessor to Lessee, or (ii) in the case of a default or a
     contingency which cannot with due diligence be cured within thirty (30)
     days, Lessee shall fail, after written notice thereof from Lessor, to
     proceed promptly and with all due diligence to commence to cure the same
     and thereafter to prosecute the curing of such default with all due
     diligence (it being intended that, in connection with a default which is
     not susceptible of being cured with due diligence within thirty (30) days
     the time of Lessee within which to cure the same shall be extended for such
     period as may be necessary for the curing thereof with all due diligence);
     or

          (3) if Lessee shall file a voluntary petition seeking an order or
     relief under Title 11 of the United States Code or similar law of any
     jurisdiction applicable to Lessee, or Lessee shall be adjudicated a debtor,
     bankrupt or insolvent, or shall file any petition or answer seeking,
     consenting to or acquiescing in any order for relief, reorganization,
     arrangement, composition, adjustment, winding-up, liquidation, dissolution
     or similar relief with respect to Lessee or its debts under the present or
     any future bankruptcy act or any other present or future applicable
     federal, state or other statute or law, or shall file an answer admitting
     or failing to deny the material allegations of a petition against it for
     any such relief or shall generally not, or shall be unable to, pay its
     debts as they become due or shall admit in writing in any filing with any
     court or Governmental Authority its insolvency or its inability to pay its
     debts as they become due, or shall make a general assignment for the
     benefit of creditors or shall seek or consent or acquiesce in the
     appointment of any trustee, receiver, examiner, assignee, sequestrator,
     custodian or liquidator or similar official of Lessee or of all or any part
     of Lessee's property or if Lessee shall take any action in furtherance of
     or authorizing any of the foregoing; or if Lessee shall call a meeting of,
     or propose any form of arrangement, composition, extension or adjustment
     with its creditors holding a majority in amount of Lessee's outstanding
     indebtedness; or

          (4) if any case, proceeding or other action shall be commenced or
     instituted against Lessee, seeking to adjudicate lessee a bankrupt or
     insolvent, or seeking an order for relief against Lessee as debtor, or
     reorganization, arrangement, composition, adjustment, winding-up,
     liquidation, dissolution or similar relief with respect to Lessee or its
     debts under the present or any future bankruptcy act or any other present
     or future applicable federal, state or other statute or law, or seeking
     appointment of any trustee, receiver, examiner, assignee, sequestrator,
     custodian or liquidator or similar official of Lessee or of all or part of
     Lessee's property, which either (i) results in the entry of an 

                                    Page 18 of 40
<PAGE>

     order for relief, adjudication of bankruptcy or insolvency or such an
     appointment or the issuance or entry of any other order having similar
     effect or (ii) remains undismissed for a period of ninety (90) days; or if
     any case, proceeding or other action shall be commenced or instituted
     against Lessee seeking issuance of a warrant of execution, attachment,
     restraint or similar process against Lessee or any of Lessee's property
     which results in the taking or occupancy of the Demised Premises or an
     attempt to take or occupy the Demised Premises which shall not have been
     vacated, discharged, or stayed or bonded pending appeal within ninety (90)
     days after the entry thereof; or

          (5) if any event shall occur or any contingency shall arise whereby
     this Lease or the estate hereby granted to the unexpired balance of the
     Term would, by operation of law or otherwise, devolve upon or pass to any
     person other than Lessee, except as is expressly permitted under Article
     27, or if default shall be made by Lessee in the performance of, or
     compliance with the covenants, agreements and conditions set forth in
     Article 27; or

          (6) if Lessee's (other than Lessee herein named) obligations under
     this Lease shall have been guaranteed by any person other than Lessee and
     such person shall default in observance or performance of any term,
     covenant or condition to be observed or performed by such person under the
     instrument or agreement containing such guarantee; or

          (7) if any financial statement or other information furnished to
     Lessor by Lessee in connection with this Lease is materially false or
     misleading; or

          (8) if Lessee shall default in the observance or performance of any
     term, covenant or condition on Lessee's part to be observed or performed
     under the provisions of Section 35.09; or

          (9) if Lessee is the subject of a Chapter 11 reorganization under the
     Bankruptcy Reform Act of 1978 and such reorganization is not confirmed
     within eighteen (18) months from the time of filing of a voluntary or
     involuntary petition thereunder (it being understood that in such event
     Lessee consents to the termination of the automatic stay provisions of
     Section 362 of such Act);

 then and in any such event (hereinafter sometimes called an "Event of Default")
Lessor may give written notice ("Termination Notice") to Lessee specifying such
Event of Default or Events of Default and stating that this Lease and the Term
shall expire and terminate on the date specified in the Termination Notice,
which shall be at least seven (7) days after the giving of the Termination
Notice, and on the date specified therein this Lease and the Term and all rights
of Lessee under this Lease shall expire and terminate, it being the intention of
the Lessor and Lessee hereby to create conditional limitations, and Lessee shall
remain liable as provided in Article 15 and in accordance with those provisions
of this Lease which are specifically stated herein to survive the expiration or
other termination of this Lease.

     B. Notwithstanding the provisions of Section 14.0l.A, if there shall be an
Event of Default at any time or from time to time under the provisions of
subdivision (1) of Section 14.0l.A, Lessor may, in lieu of giving a Termination
Notice, at any time after the occurrence of any such Event of Default and during
the continuance thereof, institute an action for the recovery of the Fixed Rent
and/or Additional Rent in respect of which an Event of Default shall have
occurred and be continuing.  Neither the commencement of any such action for the
recovery of Fixed Rent and/or Additional Rent nor the prosecution thereof shall
be deemed a waiver of Lessor's right to give a Termination Notice in respect of
any such Event of Default during the continuance thereof and Lessor may,
notwithstanding the commencement and prosecution of any such action, give a
Termination Notice and terminate this Lease pursuant to Section 14.0l.A at any
time during the continuance of such Event of Default.

     C. If, at any time, (i) Lessee shall be comprised of two or more persons,
or (ii) Lessee's obligations under this Lease shall have been guaranteed by any
person other than Lessee, or (iii) Lessee's interest in this Lease shall have
been assigned, the word "Lessee," as used in subdivisions (4), (5) and (9) of
Section 14.0l.A, shall be deemed to mean any one or more of the persons
primarily or secondarily liable for Lessee's obligations under this Lease.  Any
monies received by Lessor from or on behalf of Lessee during the pendency of any
proceeding of the types referred to in said subdivisions (4), (5) and (9) of
Section 14.0l.A shall be deemed paid as compensation for the use and occupation
of the Demised Premises and the acceptance of any such 

                                    Page 19 of 40
<PAGE>
compensation by Lessor shall not be deemed an acceptance of rent or a waiver on
the part of Lessor of any rights under Section 14.01.

     SECTION 14.02. In the event that this Lease shall be terminated as provided
in this Article, Lessor or Lessor's agents may, immediately, or at any time
thereafter, without further notice, enter upon and re-enter the Demised Premises
and possess and repossess itself thereof, by summary proceedings, ejectment or
otherwise, and have, hold and enjoy the Demised Premises and the right to
receive all income of and from the same.  No re-entry by Lessor pursuant to this
Article shall be deemed an acceptance of a surrender of this Lease nor shall it
absolve or discharge Lessee from any liability under this Lease.

     SECTION 14.03. In the event that this Lease shall be terminated as provided
in this Article, Lessor may, at any time or from time to time thereafter, relet
the Demised Premises or any part thereof, for such term or terms (which may be
greater or less than the period which would otherwise have constituted the
balance of the Term) and on such conditions (which may include concessions or
free rent, which shall, however, be amortized over the entire term for the
purpose of determining damages under Article 15) as Lessor may determine, to any
tenant which it may deem suitable and satisfactory and for any use and purpose
it may deem appropriate and may collect and receive the rents therefor.  Lessor
shall use commercially reasonable methods in making such reletting.  Lessor, at
its option, may make such repairs, alterations, additions, improvements,
decorations and other physical changes in and to the Demised Premises as Lessor
considers advisable or necessary in connection with any such reletting or
proposed reletting, without relieving Lessee of any liability under this Lease
or otherwise affecting any such liability.  Lessor shall in no way be
responsible or liable for any failure to relet the Demised Premises, or any part
thereof, or for any failure to collect any rent due upon such reletting.  Lessor
shall not in any event be required to pay Lessee (but shall credit Lessee, to
the extent set forth in Article 15, with) any sum received by Lessor on a
reletting of the Demised Premises, or any part thereof, whether or not in excess
of the rent reserved in this Lease.

     SECTION 14.04. Lessee, on its own behalf and on behalf of all persons
claiming through or under Lessee including all creditors, does hereby waive any
and all rights and privileges, so far as is permitted by law, which Lessee and
all such persons might otherwise have under any present or future law, to (i)
the service of any notice of intention to re-enter or institute legal
proceedings to that end, excluding service of process, (ii) redeem the Demised
Premises, (iii) re-enter or repossess the Demised Premises, or (iv) restore the
operation of this Lease, after Lessee shall have been dispossessed by a judgment
or by warrant of any court or judge, or after any re-entry by Lessor or after
any expiration or termination of this Lease and the Term, whether such
dispossess, re-entry, expiration or termination shall be by operation of law or
pursuant to the provisions of this Lease.  The words "re-enter," "re-entry" and
"re-entered" as used in this Lease shall not be deemed to be restricted to their
technical legal meanings.

     SECTION 14.05. In the event the Lessee shall dispute the validity or
amount, or the time or manner of payment of, any Rent claimed by Lessor to be
due from Lessee under this Lease, Lessee shall nevertheless pay the same and
such payment may be without prejudice to Lessee's position if Lessee so requests
at the time of payment.  If the dispute shall be finally determined in Lessee's
favor by a court of competent jurisdiction, Lessor shall within a reasonable
period of time not to exceed sixty (60) days pay Lessee the amount of Lessee's
overpayment of such rent.  Lessee's failure to observe and perform the
provisions of this Section shall be deemed a default under subdivision (1) of
Section 14.0l.A.

                 ARTICLE 15 - MEASURE OF DAMAGES IN EVENT OF DEFAULT

     SECTION 15.01.A. In the event that this Lease be terminated pursuant to
Article 14 as a result of an Event of Default on the part of the Lessee and
whether or not the Demised Premises be relet, Lessor shall be entitled to retain
all monies, if any, paid by Lessee to Lessor, whether as advance Rent or
otherwise, but such monies shall be credited by Lessor against any Rent due at
the time of such termination, or at Lessor's option, against any damages payable
by Lessee, and Lessor shall be entitled to recover from Lessee, and Lessee shall
pay to Lessor the following:

          (a) All Rent to the date upon which this Lease and the Term shall have
     terminated, and

          (b) All expenses reasonably incurred by Lessor in recovering
     possession of the Demised Premises (including summary proceedings),
     restoring the Demised Premises to good order and condition, maintaining the
     Demised Premises in good order and condition 
                                    Page 20 of 40
<PAGE>

     while vacant, altering or otherwise preparing the same for reletting, and
     in reletting the Demised Premises (including reasonable and customary
     brokerage commissions and legal expenses), the same to be paid by Lessee to
     Lessor on demand, and

          (c) The amount by which the rent which, but for the termination of
     this Lease, would have been payable under this Lease from the date of
     termination to the Expiration Date exceeds the rental and other income, if
     any, collected by Lessor in respect of the Demised Premises, or any part
     thereof, subject nevertheless to the provisions of Section 14.03, said
     amount to be due and payable by Lessee to Lessor on the several days on
     which the Rent reserved in this Lease would have become due and payable for
     the period which otherwise would have constituted the unexpired portion of
     the Term (that is to say, upon each of such days Lessee shall pay to Lessor
     the amount of deficiency then existing).

     B. Whether or not Lessor shall have collected any monthly deficiencies
aforesaid, Lessor shall be entitled to recover from Lessee on demand, as and for
liquidated damages, a lump sum payment equal to the amount by which the Fixed
Rent and Additional Rent payable hereunder for the period which otherwise would
have constituted the unexpired portion of the Term (due account being taken of
amounts, if any, collected under clause [c] of Section 15.0l.A, and conclusively
presuming the Additional Rent to be the same as was payable for the year
immediately preceding such termination or re-entry and thereafter increasing by
three (3%) percent per annum) exceeds the then rental value of the Demised
Premises for the same period both discounted at a rate equal to then applicable
Treasury Rate to present value.  If the Demised Premises or any part thereof be
relet by Lessor for the unexpired portion of the Term, or any part thereof,
before presentation of proof of such liquidated damages to any court, commission
or tribunal, the amount of rent reserved upon such reletting shall be deemed
PRIMA FACIE to be the fair and reasonable rental value for the part or the whole
of the Demised Premises so relet during the term of the reletting.  Nothing
herein contained shall limit or prejudice the right of the Lessor to prove for
and obtain as damages by reason of such termination an amount equal to the
maximum allowed by any statute or rule of law in effect at the time when, and
governing the proceedings in which, such damages are to be proved, whether or
not such amount be greater or less than the amount of liquidated damages
referred to above (due account to be taken, however, of the amounts, if any,
collected under this Article 15).

     SECTION 15.02. In no event shall Lessee be entitled to receive any excess
of the rental and other income collected by Lessor in respect of the Demised
Premises over the sums payable by Lessee to Lessor hereunder.  In no event shall
Lessee be entitled in any suit for the collection of damages pursuant to this
Article to a credit in respect of any such rental and other income, except to
the extent that such rental and other income is allocable to the portion of the
Term in respect of which such suit is brought and is actually received by Lessor
prior to the entry of judgment in such suit.

     SECTION 15.03. Separate actions may be maintained by Lessor against Lessee
from time to time to recover any damages which, at the commencement of any such
action, have then or theretofore become due and payable to Lessor under Article
14, without waiting until the end of the Term and without prejudice to Lessor's
right to collect damages thereafter.

                             ARTICLE 16 - INDEMNIFICATION

     SECTION 16.01. Notwithstanding that joint or concurrent liability may be
imposed upon either party by statute, ordinance, rule, regulation, order or
court decision, and notwithstanding any insurance furnished by either party
pursuant hereto or otherwise, Lessee shall and does hereby indemnify and hold
Lessor and its agents, officers, directors, and employees, harmless from and
against any and all loss, liability, fines, suits, claims, obligations, damages,
penalties, demands and actions, and costs and reasonable expenses of any kind or
nature (including architects', engineers' and attorneys' fees) due to or arising
out of any of the following:

          (a) any work or thing done in, on or about the Demised Premises,
     Building or the Property or any part thereof or any use, possession,
     occupation, condition, operation, maintenance, repair or management of the
     Demised Premises, Building or the Property or any part thereof, by Lessee
     or anyone claiming through or under Lessee or the respective employees,
     agents, licensees, contractors, servants or sublessees of Lessee or any
     such person;

                                    Page 21 of 40
<PAGE>
          (b) any act or omission on the part of Lessee or any person claiming
     through or under Lessee, or the respective employees, agents, licensees,
     invitees, contractors, servants or sublessees of Lessee or any such person;
     or

          (c) any accident or injury to any person (including death) or damage
     to property (including loss of property) occurring in, on, or about the
     Demised Premises, Building or the Property or any part thereof, due to the
     act or omission by Lessee, its employees, agents, licensees, invitees,
     contractors or servants.

     The provisions of this Section 16.01 shall survive the expiration or
termination of this Lease.  Any sums payable by Lessee to Lessor under this
Section 16.01 shall be due and payable on demand.

     SECTION 16.02. Lessor and Lessor's agents, officers, directors, and
employees shall not be liable for any of the following, however caused, other
than by negligent or wilful acts: (a) failure of any Utility Service, (b) damage
to Lessee's property on the Demised Premises caused by or resulting from any
cause whatsoever, including explosion, falling plaster, vermin, smoke, gasoline,
oil, Hazardous Materials, steam, gas, electricity, earthquake, subsidence of
land, hurricane, tornado, flood, wind or similar storms or disturbances or
water, rain, ice or snow which may be upon, or leak or flow from, any street,
road, parking lot, sewer, gas main or subsurface area, or from any part of the
Property, or leakage of gasoline, oil or other substances from pipes, pipelines,
appliances, storage tanks, sewers or plumbing works in or at the Property, or
from any other place, or from the breaking of any electrical wire or the
breaking, bursting or leaking of water or Hazardous Materials from any plumbing
or sprinkler system, or any other pipe or storage tanks in, on, under or about
the Property, (c) interference with light or other incorporeal hereditaments,
and (d) loss by theft or otherwise of Lessee's Property or the property of any
person claiming through or under Lessee.  Any employees of Lessor to whom any
property shall be entrusted by or on behalf of Lessee shall be deemed to be
acting as Lessee's agents with respect to such property and neither Lessor nor
Lessor's agents shall be liable for any loss or for damage to any such property
by theft or otherwise.  This Section 16.02 shall not be construed as a provision
for indemnification.

     SECTION 16.03. Except as otherwise provided for in this Lease, Lessor shall
and does hereby agree to indemnify, defend and hold harmless Lessee and Lessee's
agents from and against any and all loss, liability, fines, suits, claims,
obligations, damages, penalties, demands and actions, and costs and reasonable
expenses of any kind or nature (including architects' and attorneys' fees) due
to or arising out of the negligence or willful misconduct of Lessor, its agents,
officers, directors and employees.  In case of any obligation of Lessor to
indemnify Lessee pursuant to this Section, such obligation shall be subject to
and conditioned upon (x) the receipt by Lessor of prompt written notice of the
claim with respect to which indemnification is sought and (y) Lessor's having
had reasonable opportunity to conduct the defense of such claim in such manner
as it deems appropriate, with the full cooperation of Lessee, and using counsel
reasonably acceptable to Lessor.

                        ARTICLE 17 - MECHANICS AND OTHER LIENS

     SECTION 17.01. If any mechanic's, laborer's or materialman's lien shall be
at any time be filed against the Demised Premises, Building or Property, or any
part thereof with respect to any work done, or caused to be done, or labor or
materials furnished, or caused to be furnished, by Lessee or anyone claiming
through or under Lessee (except for Lessor's Work), Lessee, within thirty (30)
days after notice of the filing thereof, shall cause the same to be discharged
of record by payment, deposit, bond, order of a court of competent jurisdiction
or otherwise.  If Lessee shall fail to cause such lien to be discharged within
the period aforesaid, then, in addition to any other right or remedy, Lessor
may, but shall not be obligated to, discharge the same by bonding proceedings,
if permitted by law (and if not so permitted, by deposit in court).  Any amount
so paid by Lessor, including all reasonable and actual costs and expenses paid
by Lessor in connection therewith, together with interest thereon at the maximum
legal rate from the respective dates of Lessor's so paying any such amount, cost
or expense, shall constitute Additional Rent payable by Lessee under this Lease
and shall be paid by Lessee to Lessor on demand.

                              ARTICLE 18 - CONDEMNATION

     SECTION 18.01. If the whole of the Demised Premises, or such part thereof
as will render the remainder Untenantable, shall be acquired or condemned for
any public or quasi-public use or purpose, this Lease and the Term shall end as
of the date of vesting of title in the 
                                    Page 22 of 40
<PAGE>
condemning authority with the same effect as if said date were the Expiration
Date.  If only a part of the Demised Premises shall be so acquired or condemned
then, except as otherwise provided in this Article, this Lease and the Term
shall continue in force and effect but, from and after the date of the vesting
of title, the Fixed Rent shall be an amount which bears the same ratio to the
Fixed Rent payable immediately prior to such condemnation pursuant to this Lease
as the value of the untaken portion of the Demised Premises (appraised after
taking and repair of any damage to the Demised Premises pursuant to this
Section) bears to the value of the entire Demised Premises immediately before
the taking.  The value of the Demised Premises before and after the taking shall
be determined for the purposes of this Section by an independent licensed
appraiser chosen by Lessor.  If more than sixty (60%) percent of the total area
of the Building included in the Demised Premises immediately prior to
acquisition or condemnation is so acquired or condemned, or if by reason of such
acquisition or condemnation, Lessee no longer has reasonable means of access to
the Demised Premises, then in such event, either party, may give notice to the
other party within sixty (60) days next following the date upon which Lessee
have received notice of vesting of title, thirty (30) days notice of termination
of this Lease.  In the event any such thirty (30) day notice of termination is
given by Lessor or Lessee, this Lease and the Term shall terminate upon the
expiration of said thirty (30) days with the same effect as if that date were
the Expiration Date.  If a part of the Demised Premises shall be so acquired or
condemned, and the Term shall not be terminated pursuant to the provisions of
this Section, Lessor, at Lessor's expense, shall restore that part of the
Demised Premises not so acquired or condemned to a self-contained unit.  In the
event of any termination of this Lease and the Term pursuant to the provisions
of this Section, the Fixed Rent and Additional Rent shall be apportioned as of
the date of sooner termination and any prepaid portion of the Fixed Rent and
Additional Rent for any period after such date shall be refunded by Lessor to
Lessee, subject to the claims, if any, of Lessor against Lessee hereunder or
otherwise.

     SECTION 18.02. In the event of any acquisition or condemnation of all or
part of the Demised Premises for any public or quasi-public use or purpose,
Lessor shall be entitled to receive the entire award for such acquisition or
condemnation, Lessee shall have no claim against Lessor or the condemning
authority for the value of any unexpired portion of the Term and Lessee hereby
expressly assigns to Lessor all of its right, title and interest in and to any
such award, and also agrees to execute any and all further documents that may be
required in order to facilitate the collection thereof by Lessor.  Nothing
contained in this Section shall be deemed to prevent Lessee from making a
separate claim in any condemnation proceeding for moving expenses and for the
value of any Lessee's Property which would be removable at the end of the Term
pursuant to the provisions hereof, directly against any Governmental Authority
authorized to exercise the power of eminent domain, provided that applicable
statutes permit such awards and any award to Lessor is not diminished or
adversely affected thereby.

     SECTION 18.03. The terms "condemnation" and "acquisition" as used in this
Article shall include any agreement in lieu of or in anticipation of the
exercise of the power of eminent domain between Lessor and/or any Superior
Mortgage and any Governmental Authority authorized to exercise the power of
eminent domain.

                      ARTICLE 19 -  COVENANT OF QUIET ENJOYMENT

     SECTION 19.01. If and so long as no Event of Default shall have occurred
and be continuing, Lessor covenants and agrees that Lessee may peaceably and
quietly enjoy the Demised Premises and Lessee's possession of the Demised
Premises will not be disturbed by Lessor, its successors and assigns, subject,
however, to the terms of this Lease (including those set forth in Sections 24.01
and 24.02), the Mortgage, Superior Lease and any and/or all other agreements and
any amendments thereto, to which this Lease is subordinated.

                  ARTICLE 20 - WAIVER OF COUNTERCLAIM AND JURY TRIAL

     SECTION 20.01. In the event that Lessor shall commence any summary or other
proceedings or action for non-payment of Rent hereunder, Lessee shall not
interpose any counterclaim of any nature or description in such proceeding or
action, unless such non-interposition would effect a waiver of Lessee's right to
assert such claim against Lessor in a separate action or proceeding.  The
parties hereto waive a trial by jury on any and all issues arising in any action
or proceeding between them or their successors under or in any way connected
with this Lease or any of its provisions, any negotiations in connection
therewith, the relationship of Lessor and Lessee, or Lessee's use or occupation
of the Demised Premises, including any claim of injury or any emergency or other
statutory remedy with respect thereto.  The provisions of this Article shall
survive the expiration or other termination of this Lease.

                                 ARTICLE 21 - NOTICES

     SECTION 21.01.A. Except as otherwise expressly provided in this Lease, any
bills, statements, notices, demands, requests, consents or other communications
given or required to be given under this Lease shall be effective only if
rendered or given in writing and

          (a) If to Lessee, then, at the option of Lessor, (i) addressed to
     Lessee's address as set forth in this Lease with a copy thereof to Lessee
     at One Meadowlands Plaza, East Rutherford, New Jersey 07073, Attention:
     General Counsel, or to such other address as Lessee may designate as its
     new address for such purpose by notice given to Lessor in accordance with
     the provisions of this Section, or (ii) delivered personally to Lessee, or
     (iii) by overnight courier,

          (b) If to Lessor, sent by personal delivery or overnight courier,
     addressed to Lessor at Lessor's address as set forth in this Lease, with a
     copy thereof to Hirsch & Katz, LLP, 595 Stewart Avenue, Suite 400, Garden
     City, New York 11530, Attention: Steven C. Hirsch, Esq., or to such other
     address as Lessor may designate as its new address for such purpose by
     notice given to Lessee in accordance with the provisions of this Section.

     B. Any such bill, statement, notice, demand, request, consent or other
communication shall be deemed to have been rendered or given: (i) on the date
delivered, if delivered to Lessee personally, or by overnight courier and
(ii) on the expiration of five (5) days after mailing, if mailed to Lessor or
Lessee as provided in this Section.  Any notice by a party signed by counsel for
such party shall be deemed a notice signed by such party.

                 ARTICLE 22 - WAIVERS AND SURRENDERS TO BE IN WRITING

     SECTION 22.01. The receipt of full or partial Rent by Lessor with knowledge
of any breach of this Lease by Lessee or of any default on the part of the
Lessee in the observance or performance of any of the provisions or covenants of
this Lease shall not be deemed to be a waiver of any such provision, covenant or
breach of this Lease, PROVIDED, HOWEVER, that acceptance of a payment of Rent
shall be valid PRO TANTO.  No waiver or modification by Lessor, unless in
writing, and signed by Lessor, shall discharge or invalidate any provision or
covenant or affect the right of Lessor to enforce the same in the event of any
subsequent breach or default.  The failure on the part of Lessor to insist in
any one or more instances upon the strict performance of any of the provisions
or covenants of this Lease, or to enforce any covenant or provision herein
contained or to exercise any right, remedy or election herein contained
consequent upon a breach of any provision of this Lease, shall not affect or
alter this Lease or be construed as a waiver or relinquishment for the future of
such one or more provisions or covenants or of the right to insist upon strict
performance or to exercise such right, remedy or election, but the same shall
continue and remain in full force and effect with respect to any existing or
subsequent breach, act or omission, whether of a similar nature or otherwise. 
The receipt by Lessor of any rent or any other sum of money or any other
consideration hereunder paid by Lessee after the termination, in any manner, of
the Term, or after the giving by Lessor of the Termination Notice, shall not
reinstate, continue or extend the Term, or destroy, or in any manner impair the
efficacy of any such Termination Notice, as may have been given hereunder by
Lessor to Lessee prior to the receipt of any such Rent, or other sum of money or
other consideration, unless so agreed to in writing and signed by Lessor. 
Neither acceptance of the keys or any other act or thing done by Lessor or any
agent or employee shall be deemed to be an acceptance of a surrender of the
Demised Premises, or any part thereof, excepting only an agreement in writing
signed by Lessor.  No payment by Lessee or receipt by Lessor of a lesser amount
than the correct Rent shall be deemed to be other than a payment on account, nor
shall any endorsement or statement on any check, as distinguished from any
letter accompanying such check or payment, be deemed to effect or evidence an
accord and satisfaction, and Lessor may accept such check or payment without
prejudice to Lessor's right to recover the balance or pursue any other remedy in
this Lease provided.

     SECTION 22.02. No waiver or modification by Lessee, unless in writing, and
signed by Lessee, shall discharge or invalidate any provision or covenant or
affect the right of Lessee to enforce the same in the event of any subsequent
breach or default.  The failure on the part of Lessee to insist in any one or
more instances upon the strict performance of any of the provisions or covenants
of this Lease, or to enforce any covenant or provision herein contained or to
exercise any right, remedy or election herein contained consequent upon a breach
of any provision of this Lease, shall not affect or alter this Lease or be
construed as a waiver or relinquishment for the future of such one or more
provisions or covenants or of the right to insist 
                                    Page 24 of 40
<PAGE>

upon strict performance or to exercise such right, remedy or election, but the
same shall continue and remain in full force and effect with respect to any
existing or subsequent breach, act or omission, whether of a similar nature or
otherwise.

                            ARTICLE 23 - RIGHTS CUMULATIVE

     SECTION 23.01. Each right and remedy of Lessor shall be cumulative and to
the extent permitted by law, the exercise or beginning of the exercise by Lessor
of any one or more of the rights or remedies of such party shall not preclude
the simultaneous or later exercise by Lessor of any or all other rights or
remedies; PROVIDED, HOWEVER, that this sentence shall not be construed to
entitle Lessor to satisfaction of more than one remedy in respect of a
particular breach.  In the event of any breach or threatened breach by Lessee or
any persons claiming through or under Lessee of any of the agreements, terms,
covenants or conditions contained in this Lease, Lessor shall be entitled to
enjoin such breach or threatened breach (if entitled to do so at law or in
equity or by statute or otherwise) and shall have the right to invoke any right
or remedy allowed by law or in equity or by statute or otherwise as if re-entry,
summary proceedings or other specific remedies were not provided for in this
Lease.

                    ARTICLE 24 - CONVEYANCE; LIABILITY OF PARTIES

     SECTION 24.01. The term "Lessor" as used herein shall mean and include only
the owner or owners at the time in question of the Lessor's interest in this
Lease so that in the event of any transfer or transfers (by operation of law or
otherwise) of Lessor's entire interest in this Lease, Lessor herein named (and
in the case of any subsequent transfers or conveyances, the then transferor)
shall be and hereby is automatically freed and relieved, from and after the date
of such transfer or conveyance, of all liability in respect of the performance
of any covenants or obligations on the part of the Lessor contained in this
Lease thereafter to be performed, provided that the transferee shall be deemed
to have assumed and agreed to perform subject to the limitation of this Article
(and without further agreement between or among the parties or their successors
in interest, and/or the transferee) and only during and in respect of the
transferee's period of ownership, all of the terms, covenants and conditions in
this Lease contained on the part of Lessor to be performed, which terms,
covenants, and conditions shall be deemed to "run with the land," it being
intended hereby that the terms, covenants and conditions contained in this Lease
or the part of the Lessor to be performed shall, subject as aforesaid, be
binding on Lessor, its successors and assigns, only during and in respect of
their respective successive periods of ownership.

     SECTION 24.02. In the event of a breach by Lessor of any provisions,
covenants or obligations of this Lease to be performed by Lessor, the monetary
liability of Lessor in relation to any such breach shall be limited to the
equity of Lessor in the Demised Premises, and Lessee shall look only to Lessor's
equity in the Demised Premises for the performance and observance of the terms,
covenants, conditions and obligations of this Lease to be performed or observed
by Lessor and for the satisfaction of Lessee's remedies for the collection of
any award, judgment or other judicial process requiring the payment of money by
Lessor in the event of a default in the full and prompt payment and performance
of any Lessor's obligations hereunder and in no event shall any of the partners
constituting Lessor (the "Partners"), nor the partners, shareholders, officers
or directors of Lessor or the Partners shall be liable for the performance of
Lessor's obligations under this Lease, nor shall any of the Partners assets be
liable to any levy, execution, restraint, award, claim of any kind whatsoever
arising out of, or in any way related to this Lease.

     SECTION 24.03. The term "Lessee" as used in this Lease shall mean and
include Lessee named herein and, during and in respect of their respective
successive periods of ownership, each subsequent owner or owners of the
leasehold estate created by this Lease.  For all purposes of this Lease and
without affecting the rights of, and obligations between, Lessee herein named
and any transferee, notwithstanding any transfer (by operation or law or
otherwise) of title to the leasehold estate created by this Lease by Lessee
herein named or by any subsequent owner of such estate and notwithstanding the
assumption by any transferee of the obligations of the Lessee hereunder, Lessee
herein named, as between Lessor and Lessee herein named, shall remain primarily
liable as primary obligor and not as a surety, for the full and prompt payment
and performance of Lessee's obligations hereunder and, without limiting the
generality of the foregoing or of Article 28, shall remain fully and directly
responsible and liable to Lessor for all acts and omissions on the part of any
transferee subsequent to it in violation of any obligation of this Lease.

                    ARTICLE 25 - CHANGES AND ALTERATIONS BY LESSEE

     SECTION 25.01.A. Lessee shall have no right to make any alteration, change,
additions or improvement, structural or otherwise (an "Alteration"), to the
Demised Premises or any appurtenances thereto without the prior written consent
of Lessor in each instance, which consent shall not be unreasonably withheld.

     B. If Lessor shall grant its consent to the making of an Alteration, then
the same shall (i) be performed at the sole cost and expense of Lessee, (ii) be
performed in a good and workmanlike manner, and in compliance with all
applicable Legal Requirements (including existing zoning requirements),
Insurance Requirements and Environmental Laws, (iii) be consistent with the use
of the Demised Premises provided for herein, (iv) not in any way render the
Demised Premises other than a complete, self containing operating unit, (v) in
the case of a structural alteration, be performed in accordance with plans and
specifications approved prior to the commencement of any work by the appropriate
Governmental Authorities and by Lessor, (vi) be of such nature so as not to
lessen the fair market value of the Demised Premises, and (vii) be performed
under the supervision of a licensed architect approved by Lessor and in
accordance with Lessor's STANDARD REQUIREMENTS FOR ALTERATIONS TO BE PERFORMED
BY LESSEES', as may be amended from time to time.

     SECTION 25.02.A. Any and all Alterations made in accordance with
Section 25.01 shall immediately become the property of Lessor, PROVIDED,
HOWEVER, that if, in accordance with the provisions of Sections 25.02.B and
29.02, Lessee shall have the option to and shall remove its trade fixtures,
provided that same are not affixed to or such removal would otherwise damage the
Demised Premises, then the same shall cease to be property of the Lessor upon
removal.

     B. Unless Lessor shall otherwise expressly indicate in writing at the time
of granting its consent to the making of a proposed Alteration, Lessee shall, as
and when provided in Section 29.02, restore the affected portion of the Demised
Premises to the state or condition thereof existing prior to the making of such
Alteration.

     C. Any and all contractors to be involved in performing work shall be
subject to Lessor's prior approval, which shall not be unreasonably withheld.

     D. Prior to commencing any work at the Demised Premises, Lessee shall
furnish Lessor with evidence reasonably satisfactory to Lessor of such insurance
as Lessor may require and such insurance shall be in full force and effect
during such work and will cover, by endorsement or otherwise, the risk during
the course of such work.

     E. In the event of any Alteration as provided for in this Article, the Rent
payable hereunder shall not be reduced or abated in any manner whatsoever,
except as specifically provided for in Article 3 hereof.  

     F. No Alterations shall involve the removal of any fixtures, equipment or
other property in the Demised Premises which are not Lessee's property, unless
Lessor's prior written consent is first obtained and unless such fixtures,
equipment or other property shall be promptly replaced, at Lessee's expense and
free of superior title, liens and claims, with fixtures, equipment or other
property (as the case may be) of like utility and at least equal value (which
replaced fixtures, equipment or other property shall thereupon become the
property of Lessor), unless Lessor shall otherwise expressly consent in writing.

     SECTION 25.03. Notwithstanding anything herein to the contrary, Lessor
(which term shall mean Lessor and/or Lessor's affiliated general contractor)
shall have the right to bid on any and all Alterations pursuant to Article 25 of
this Lease.  In the event that Lessor is not the successful bidder, then in such
event, Lessor (which term shall mean Lessor and/or Lessor's affiliated general
contractor) shall be entitled to a general supervisory fee of Five (5%) percent
to supervise all such Alterations.

                          ARTICLE 26 - CERTIFICATE OF LESSEE

     SECTION 26.01. Lessee agrees at any time and from time to time, within
twenty (20) days after receiving written request by Lessor, to execute,
acknowledge and deliver a statement certifying (i) the Commencement Date and/or
Rent Commencement Date hereunder, (ii) that this Lease is unmodified and in full
force and effect (or if there have been modifications, that the Lease is in full
force and effect as modified and stating the modifications), (iii) the dates to
which the Fixed Rent and Additional Rent have been paid, and (iv) whether or not
to the knowledge of 

                                    Page 26 of 40
<PAGE>

the signer of such statement (a) Lessor is in default in keeping, observing or
performing any term, covenant, agreement, provision, condition or limitation
contained in this Lease and, if in default, specifying each such default,
(b) either party is holding any funds under this Lease in which the other has an
interest (and, if so, specifying the party holding such funds and the nature and
amount thereof), and (c) there is any amount then due and payable to Lessee by
Lessor, it being intended that any such statement delivered pursuant to this
Section may be relied upon by Lessor, any mortgagee, superior lessor or any
person who may and does become a mortgagee, superior lessee, any person who may
and does become a purchaser or assignee of Lessor's interest in this Lease or
the mortgagee's interest in any mortgage or the Lessor's interest in the
Superior Lease.

                  ARTICLE 27 - ASSIGNMENTS, SUBLEASES AND MORTGAGES

     SECTION 27.01.A. Except as otherwise specifically provided in this Article,
neither this Lease, nor the Term and estate hereby granted, nor any part
thereof, nor the interest of Lessee in any sublease or the rental thereunder,
shall be assigned, mortgaged, pledged, encumbered or otherwise transferred by
Lessee or Lessee's legal representatives or successors in interest, by operation
of law or otherwise, and neither the Demised Premises, nor any part thereof, nor
any Lessee's Property, shall be encumbered in any manner by reason of any act or
omission on the part of Lessee or anyone claiming under or through Lessee, or
shall be sublet or be used or occupied or permitted to be used or occupied or
utilized for desk or storage space by anyone other than Lessee or for any
purpose other than as specifically permitted by this Lease, without the prior
written consent of Lessor in each case, which consent may be withheld for any
reason whatsoever.  If Lessee is other than a public company, a transfer
(including any issuance of stock) of an aggregate of fifty (50%) percent or more
stock, partnership interest or other equity interest in Lessee by any party or
parties in interest shall be deemed an assignment of this Lease.

     B. If Lessee is a corporation, upon at least thirty (30) days prior notice
to Lessor, this Lease in its entirety may be assigned without Lessor's consent
to a corporation into which Lessee merges or consolidates, or which controls, is
controlled by or under common control with Lessee, so long as the Demised
Premises continue to be used for the use described in Article 4 of this Lease;
the transfer is not principally for the purpose of transferring the leasehold
estate created hereby; the net worth of the assignee is at least equal to or in
excess of the net worth of Lessee at the time of execution of this Lease and
immediately prior to such assignment or the assignee can otherwise secure and
guaranty the payment to Lessor of all rent and any other amounts due from Lessee
pursuant to this Lease in a manner reasonably satisfactory to Lessor; the
assignee assumes by documents satisfactory to Lessor all of Lessee's obligations
to be performed under this Lease, and; provided such assignment shall be subject
to all of the other terms and conditions of this Lease.

     SECTION 27.02. If this Lease be assigned, whether or not in violation of
the provisions of this Lease, Lessor may collect rent from the assignee, and
Lessor shall be entitled to receive, as Additional, Rent, all the excess
consideration paid to Lessee in connection with such assignment as shall for any
period exceed the aggregate of the Rents payable under this Lease (the "Excess
Consideration").  Such Excess Consideration shall be reduced by the reasonable
cost of tenant improvements, rent concessions, and brokerage commissions
reasonably incurred by Lessee for such assignment, and the net amount thereof
shall be paid to Lessor either: (i) in a lump sum, (ii) or allocated to such
period on a straight line basis over the term of such assignment if paid in
installments, as the case may be, promptly after receipt thereof by Lessee.  The
provisions of the preceding sentence shall be in full force and effect
notwithstanding that Lessee has sought the protection of any provisions of the
bankruptcy law (as hereinafter defined) or if a petition has been filed against
Lessee under such bankruptcy law.  If the Demised Premises or any part thereof
be sublet or be used or occupied by anybody other than Lessee, whether or not in
violation of this Lease, Lessor may, after default by Lessee and expiration of
Lessee's time to cure such default, if any, collect rent from the sublessee or
occupant.  In either event, Lessor may apply the net amount collected to the
rents herein reserved, but no such assignment, subletting, occupancy or
collection shall be deemed a waiver of any of the provisions of Section 27.01,
or the acceptance of the assignee, sublessee or occupant as tenant, or a release
of Lessee from the further performance by Lessee of Lessee's obligations under
this Lease.  The consent by Lessor to an assignment, mortgaging or subletting
pursuant to any provision of this Lease shall not in any way be considered to
relieve Lessee from obtaining the express consent of Lessor for any other or
further assignment, mortgaging or subletting.  References in this Lease to use
or occupancy by anyone other than Lessee shall not be construed as limited to
sublessees and those claiming under or through sublessees but as including also
licensees and others claiming under or through Lessee, immediately or remotely. 
The listing of any name other than that of Lessee on any door of the Demised
Premises or on any sign on the Demised Premises, or 

                                    Page 27 of 40
<PAGE>

otherwise, shall not operate to vest in the person so named any right or
interest in this Lease or in the Demised Premises, or be deemed to constitute,
or serve as a substitute for, any prior consent of Lessor required under this
Article, and it is understood that any such listing shall constitute a privilege
extended by Lessor which shall be revocable at Lessor's will by notice to
Lessee.  Lessee agrees to pay to Lessor any reasonable counsel fees incurred by
Lessor in connection with any proposed assignment of Lessee's interest in this
Lease or any proposed subletting of the Demised Premises or any part thereof. 
Neither any assignment of Lessee's interest in this Lease nor any subletting,
occupancy or use of the Demised Premises or any part thereof by any person other
than Lessee as provided in this Article, nor any application of any such rent as
provided in this Article shall, under any circumstances, relieve Lessee herein
named of its obligations fully to observe and perform the terms, covenants and
conditions of this Lease on Lessee's part to be observed and performed.

     SECTION 27.03.A. Notwithstanding anything contained in Sections 27.01 and
27.02, in the event that, at any time or from time to time during the Term,
Lessee desires to sublet all or any part of the Demised Premises, Lessee shall
notify Lessor of such desire and shall: (i) submit to Lessor in writing the name
and address of the proposed subtenant, a reasonably detailed statement of the
proposed subtenant's business, reasonably detailed financial references for the
proposed subtenant and any other information reasonably requested by Lessor, and
(ii) submit to Lessor a copy of the proposed sublease.


     B. If a proposed assignment or sublease requires Lessor's consent, then
upon receipt of such notice Lessor shall thereupon have the option and right,
exercisable within ten (10) days of receipt of such notice from Lessee, to
terminate this Lease effective as of a date specified by Lessor in such notice
which date shall not be later than thirty (30) days after the date of Lessor's
notice.  Notwithstanding the foregoing, Lessor shall not have the right to
terminate this Lease in connection with a collateral assignment of the Lease
which Lessor has consented to.

     C. If within fifteen (15) days after Lessee shall have requested the
consent of Lessor to any assignment or subletting under this Article, and shall
have submitted all items required hereby, Lessor does not exercise its option to
terminate this Lease, the term of the proposed assignment or sublease may
commence upon Lessor's consent, which consent may not be unreasonably withheld,
it being agreed that if within such fifteen (15) day period Lessor does not
advise Lessee that such consent is not granted, such consent shall be deemed
granted by Lessor.  Lessor, however, shall not in any event be obligated to
consent to the proposed sublease or the commencement of the term unless: (i) in
the reasonable judgment of Lessor the proposed subtenant is of a character and
financial worth such as is in keeping with the standards of Lessor in those
respects for the Demised Premises, and the nature of the proposed subtenant's
business and its reputation are in keeping with the character of the Demised
Premises and the use thereof, (ii) the purpose for which the proposed subtenant
intends to use the portion of the Demised Premises sublet to it are uses
expressly permitted by and not expressly prohibited by this Lease; (iii) the
proposed sublease shall prohibit any further assignment or subletting, except in
accordance with the terms of this Lease; (iv) no Event of Default shall have
occurred and be continuing and (v) Lessee shall reimburse Lessor for all
reasonable costs that may be incurred by Lessor in connection with any sublease
or assignment, including the costs of making investigations as to the
acceptability of a proposed subtenant or assignee and legal costs incurred in
connection with the granting of any requested consent.

     D. With respect to each and every subletting authorized by the provisions
of this Article it is further agreed and understood between Lessor and Lessee
that: (i) the subletting shall be, and each such sublease shall expressly
provide that is, subject and subordinate at all times and in all respects, to
this Lease, (ii) no subletting shall be for a term ending later than one day
prior to the Expiration Date originally provided for herein and that part, if
any, of the proposed term of any sublease which shall extend beyond a date one
day prior to the Expiration Date originally provided for herein (or any sooner
date of the expiration of the term or termination of this Lease) is hereby
deemed to be a nullity, (iii) there shall be delivered to Lessor, within ten
(10) days after the commencement of the term of the proposed sublease, notice of
such commencement and a fully executed copy of the proposed sublease (unless
previously submitted) and (iv) Lessee shall pay to Lessor, as Additional Rent,
all of the rents, additional charges and other consideration arising from such
subletting as shall for any period exceed the aggregate of the Rents payable
under this Lease for the subleased space of the same period less the brokerage
commissions and attorneys' fees and disbursements reasonably incurred by Lessee
for such subletting, allocated to such period on a straight line basis over the
term of such subletting.

     E. Anything herein contained to the contrary notwithstanding: (i) Lessee
shall not advertise but may list its space for subletting or assignment, and may
list its space at a rental rate 

                                    Page 28 of 40
<PAGE>

lower than the rental rate then being paid by Lessee to Lessor only with respect
to subletting (but not assignment) and (ii) No assignment or subletting shall be
made to any person or entity which shall at that time otherwise be a tenant,
sub-tenant or other occupant of any part of the Property or which shall within
the prior six (6) months have been negotiating with Lessor to become such a
tenant, sub-tenant or occupant of the Property, unless such person or entity
desires the Demised Premises solely for expansion purposes and not for
relocating its business and Lessor has no space available to satisfy such person
or entity's needs.

                              ARTICLE 28 - SUBORDINATION

     SECTION 28.01. Subject to the provisions of Section 28.02, this Lease, and
all rights of Lessee hereunder, are and shall be subject and subordinate in all
respects to (a) all present and future ground leases, overriding leases and
underlying leases and/or grants of term of the Property, the Building, the
Building Equipment and/or any appurtenance thereto of which Lessor has notified
Lessee (collectively, the "Superior Lease"), (b) all mortgages and building loan
agreements, including leasehold mortgages, deeds of trust, and building loan
agreements, which may now or hereafter affect the Property, the Building, the
Building Equipment and/or any appurtenance thereto, of which Lessor has notified
Lessee (collectively, the "Mortgage"), whether or not the Mortgage shall also
cover other land and/or buildings, and (c) each and every advance made or
hereafter to be made under the Mortgage and to all renewals, modifications,
replacements, substitutions and extensions of any Superior Lease and the
Mortgage and spreaders and consolidations of the Mortgage.  The provisions of
this Section shall be self-operative and no further instrument of subordination
shall be required.  In confirmation of such subordination, Lessee shall promptly
execute and deliver, at its own cost and expense, an instrument in recordable
form to evidence such subordination.  If, in connection with the obtaining,
continuing or renewing of financing for which the Demised Premises or the
interest of the lessee under the Superior Lease represents collateral in whole
or in part, a bank, insurance company or other lender shall request reasonable
modifications of this Lease as a condition of such financing, Lessee will not
unreasonably withhold or delay its consent thereto, provided that such
modifications do not increase the monetary obligations of Lessee under this
Lease or materially increase the other obligations of Lessee hereunder or
materially and adversely affect the rights of Lessee under this Lease. 
Notwithstanding the foregoing, Lessor represents that as of the date hereof, the
Property and Building are not encumbered by a Superior Lease or Mortgage.

     SECTION 28.02. The subordination provided in Section 28.01 shall be
effective as between Lessee herein named and any lessor under a future Superior
Lease, or any holder of a future Mortgage, as the case may be, only if such
lessor or holder delivers to Lessee an agreement providing in substance, that if
and so long as no Event of Default shall have occurred and be continuing, this
Lease shall continue upon its then executory terms and conditions and possession
of the Demised Premises held by Lessee herein named will not be disturbed by
such person in the event of a default under the underlying lease or the
Mortgage, as the case may be.  The foregoing provisions of this Section shall
endure to the benefit of Lessee herein named and shall apply notwithstanding
that, as a matter of law, this Lease may terminate upon the termination of the
Superior Lease, or the foreclosure (including judgment of foreclosure and sale)
of the Mortgage.

     SECTION 28.03. If at any time prior to the expiration of the Term, the
holder of the Mortgage shall become the owner of the Demised Premises as a
result of foreclosure of its mortgage or by reason of an assignment of the
lessee's interest under any such lease or conveyance of the Demised Premises,
Lessee agrees, at the election and upon demand of any owner of the Demised
Premises, or of the holder of any Mortgage or Superior Lease (including a
leasehold mortgage) in possession of the Demised Premises, to attorn, from time
to time, to any such owner, or lessee, upon the then executory terms and
conditions of this Lease, provided that such owner, holder or lessee, as the
case may be, shall then be entitled to possession of the Demised Premises.  No
such owner, holder or lessee shall be liable for any previous acts or omission
of Lessor under this Lease (except that this provision shall not be construed to
relieve such person from any obligation thereafter to be performed), nor shall
such owner, holder or Lessee be subject to any offset which shall have
theretofore accrued to Lessee against Lessor, or be bound by any previous
modification of this Lease, not expressly provided for in this Lease, entered
into after the date of the Mortgage, or Superior Lease, or by any previous
prepayment of more than one month's Fixed Rent.  The foregoing provisions of
this Section shall enure to the benefit of any such owner, holder or lessee,
shall apply notwithstanding that, as a matter of law, this Lease may terminate
upon the termination of the Superior Lease, or the foreclosure (including
judgment of foreclosure and sale) of the Mortgage, shall be self-operative upon
any such demand, and no further instrument shall be required to give effect to
said provisions.  Lessee, however, upon demand of any such owner, holder or
lessee, agrees to execute, from time 

                                    Page 29 of 40
<PAGE>
to time, instruments in confirmation of the foregoing provisions of this
Section, acknowledging such attornment and setting forth the terms and
conditions of its tenancy.  Nothing contained in this Section shall be construed
to impair any right otherwise exercisable by any such owner, holder or lessee.

                 ARTICLE 29 - SURRENDER; REMOVAL OF LESSEE'S PROPERTY

     SECTION 29.01. On the last day of the Term or on the earlier termination of
the Term, Lessee shall peaceably and quietly leave, surrender and deliver the
Demised Premises to Lessor, together with (a) all alterations, changes,
additions and improvements, which may have been made upon the Demised Premises,
and (b) except for Lessee's Property, all fixtures and articles of personal
property of any kind or nature which Lessee may have installed or affixed on,
in, or to the Demised Premises for use in connection with the operation and
maintenance of the Demised Premises (whether or not said property be deemed to
be fixtures), all of the foregoing to be surrendered in good, substantial and
sufficient repair, order and condition, reasonable use, wear and tear, and
damage by fire or other casualty, excepted, and free of occupants and
sublessees.

     SECTION 29.02. On or prior to the Expiration Date or any earlier
termination of this Lease, Lessee shall remove Lessee's Property, and any items
referred to in clauses (a) or (b) of Section 29.01, which Lessor shall request
Lessee to remove (unless Lessor shall have waived such right as to any item
referred to in clause (a) of Section 29.01 at the time of the granting of
consent with respect thereto under Article 25), and Lessee shall pay or cause to
be paid the cost of repairing or remedying any damage caused thereby, provided
that no item of Lessee's Property may be removed if its removal would impair the
integrity (structural or otherwise) of the Building or Building Equipment.  All
property not so removed shall be deemed abandoned and may either be retained by
Lessor as its property or disposed of, without accountability, at Lessee's sole
cost, expense and risk, in such manner as Lessor may see fit.

     SECTION 29.03. If the Demised Premises are not surrendered in accordance
with the provisions of this Article upon the expiration or termination of this
Lease, Lessor shall have all rights given at law or in equity, in the case of
holdovers, to remove Lessee and anyone claiming through or under Lessee.  In any
event, Lessee shall and does hereby indemnify Lessor against all loss or
liability arising from delay by Lessee in so surrendering the Demised Premises,
including any claims made by and succeeding lessees founded on such delay. 
Lessee expressly waives, for itself and for any person claiming through or under
Lessee (including creditors), any rights which Lessee or any such person may
have under the provisions of any law in connection with any holdover summary
proceedings which Lessor may institute to enforce the provisions of this
Article.  Lessee's obligations under this Article shall survive the expiration
or termination of this Lease.

     SECTION 29.04. Lessee acknowledges the extreme importance to Lessor that
possession of the Demised Premises be surrendered at the expiration or sooner
termination of this Lease.  In the event that Lessee fails to vacate the Demised
Premises at the expiration or sooner termination of this Lease, Lessee shall be
obligated to pay Lessor damages in an amount equal to twice the amount of annual
Fixed Rent and Additional Rent provided for on the day preceding the Expiration
Date for such period of time that Lessee holds over on a per diem basis.

                              ARTICLE 30 - RENEWAL TERM

     SECTION 30.01. Lessee named herein, shall have the right, at its option, to
extend this Lease for a term ("Renewal Term") of five (5) years (to commence on
the Expiration Date originally provided for herein and to end at noon on the
Fifth (5th) Anniversary of such Expiration Date originally provided for herein)
by giving Lessor notice of such election at any time but not less than Nine (9)
months prior to the Expiration Date originally provided for herein (time being
of the essence with respect thereto), and upon the giving of such notice this
Lease thereupon shall, subject to the provisions of Section 30.02, be
automatically extended for the Renewal Term with the same force and effect as if
the Renewal Term had been originally included in the Term, without the execution
of any further instrument.

     SECTION 30.02. Any notice of election to exercise the option to extend as
hereinbefore provided must be in writing and sent to Lessor as provided in
Article 21.  Neither the option granted to Lessee in this Article to extend the
Term, nor the exercise of such option by Lessee, named herein shall prevent
Lessor from exercising any option or right granted or reserved to Lessor in this
Lease to terminate this Lease, and the effective exercise of any such right of
termination by Lessor shall terminate any such renewal or extension and any
right of Lessee to 
                                    Page 30 of 40
<PAGE>

any such renewal or extension, whether or not Lessee shall have exercised any
such option to extend the Term.  Any such option or right on the part of Lessor
to terminate this Lease pursuant to the provisions hereof shall continue during
any Renewal Term.

     SECTION 30.03. All of the terms, covenants and conditions of this Lease
shall continue in full force and effect during the Renewal Term except that
(i) the Fixed Rent for the Renewal Term shall be as provided in Section 30.04
(all other rent and charges payable by Lessee remaining unaffected), and
(b) there shall be no further privilege of extension of this Lease beyond the
Renewal Term. 

     SECTION 30.04.A. During the Renewal Term, Lessee shall pay to Lessor annual
Fixed Rent, at the same times and in the same manner as in the Term originally
provided for, at the annual rate equal to the annual fair rental value of the
Demised Premises (with deduction for the cash value of free rent and leasehold
improvements), which renewing, non-equity tenants are then receiving in
connection with a lease for comparable space in a building of the same age,
quality, size, location, services, amenities, quality of construction and
appearance to that of the Building on the date of the commencement of the
Renewal Term with a term equal to the Renewal Term and otherwise containing the
same provisions as this Lease contains, as determined by agreement between
Lessor and Lessee.  If, prior to the commencement of the Renewal Term, Lessor
and Lessee are unable to agree on the amount of the annual Fixed Rent during the
Renewal Term, then in such event, the determination of such annual fair rental
value shall be made by arbitration pursuant to the provisions of
Section 30.04.B. hereof.  If the Renewal Term shall commence prior to
determination of the amount of annual Fixed Rent payable during the Renewal
Term, either by agreement or by decision of the arbitrators, Lessee, in the
meantime, shall pay the monthly installments of Fixed Rent at the annual rate
payable under this Lease for the year ending on the Expiration Date originally
provided for herein.  If monthly installments of the amount agreed upon by
Lessor and Lessee, or found by the arbitrators, shall be greater than such
amount, then Lessee, forthwith after such agreement or arbitrator's decision,
shall pay to Lessor, for the period from the commencement of the Renewal Term to
the last day of the calendar month in which the agreement or the arbitrators'
decision takes effect, the difference between the monthly installments actually
paid and the monthly installments which should have been paid in accordance with
such agreement or arbitrators' decision, together with interest at the prime
rate plus two (2%) percent from the respective due dates of each monthly
installment to the date of payment pursuant to this paragraph; and, thereafter,
Lessee shall pay the monthly installments at the new rate.  In no event shall
the annual Fixed Rent during the Renewal Term be less than the annual Fixed Rent
payable immediately prior to the Renewal Term.

     B.(1) In the event that Lessor and Lessee are unable to agree on the amount
of the annual Fixed Rent during the Renewal Term, then either Lessor or Lessee
(hereinafter referred to as the "Initiating Party") may give the other party
(hereinafter called the "Responding Party") a notice designating the name and
address of the arbitrator designated by the Initiating Party to act on its
behalf in the arbitration process hereinafter described (the "Review Notice").

     (2) If the Initiating Party gives a Review Notice, then within twenty (20)
days after giving of such Review Notice, the Responding Party shall give notice
to Initiating Party specifying in such notice the name and address of the
arbitrator designated by the Responding Party to act on its behalf.  In the
event the Responding Party shall fail to give such notice within such twenty
(20) day period, then the appointment of such arbitrator shall be made in the
same manner as hereinafter provided for the appointment of a third arbitrator in
a case where two arbitrators are appointed hereunder and the parties are unable
to agree to such appointment.  The two arbitrators so chosen shall meet within
thirty (30) days after the second arbitrator is appointed and shall exchange
sealed envelopes each containing such arbitrators written determination of the
fair market rent of the Demised Premises based on the criteria set forth in
Section 30.04.A. The fair market rent specified by Lessor's arbitrator shall be
called the "Lessor's Submitted Value" and the fair market rent specified by
Lessee's arbitrator shall be called the "Lessee's Submitted Value."  Copies of
such written determinations shall promptly be sent to both Lessor and Lessee. 
Any failure of either such arbitrator to meet and exchange such determinations
shall be acceptance of the other party's arbitrator's determination as to fair
market rent, if, and only if, such failure persists for five (5) days after
notice to whom such arbitrator is acting, and, provided that such five (5) day
period shall be extended by reason of any Unavoidable Delay.  If the higher
determination of the fair market rent for the Demised Premises is not more than
one hundred and five (105%) percent of the lower determination of the fair
market rent, then the fair market rent for such space shall be deemed to be the
average of the two determinations.  If, however, the higher determination is
more than one hundred and five (105%) percent of the lower determination, then
within ten (10) days of the date the arbitrators submitted their respective fair
market rent determinations, the two arbitrators shall appoint a third
arbitrator.  In the event of 

                                    Page 31 of 40
<PAGE>
their being unable to agree upon such appointment within ten (10) days after the
exchange of the sealed envelopes, the third arbitrator shall be selected by the
parties themselves if they can agree thereon within a further period of 10 days.
If the parties do not so agree, then either party, on behalf of both and on
notice to the other, may request such an appointment by the American Arbitration
Association (or any successor organization) in accordance with its rules then
prevailing or if the American Arbitration Association (or any successor
organization) shall fail to appoint said third arbitrator within fifteen (15)
days after such request is made, then either party may apply for such
appointment, on notice to the other, to the President of the Westchester County
Bar Association (who may consult with the Chairman of the Real Property Law
Committee of the Westchester County Bar Association).  Within ten (10) days
after the appointment of such third arbitrator, the Lessor's arbitrator shall
submit Lessor's Submitted Value to such third arbitrator and the Lessee's
arbitrator shall submit Lessee's Submitted Value to such third arbitrator.  Such
third arbitrator shall, within thirty (30) days after the end of such fifteen
(15) day period, make his own determination of the fair market rent of the
Demised Premises using the criteria set forth in Section 30.04.A. hereof, and
send copies of his determination promptly to both Lessor and Lessee specifying
whether Lessor's Submitted Value or Lessee's Submitted Value was closer to the
determination by such third arbitrator of the fair market rent of the Demised
Premises.  Whichever of Lessor's Submitted Value or Lessee's Submitted Value
shall be closer to the determination by such third arbitrator shall conclusively
be deemed to be the fair market rent of the Demised Premises.

     (3) In no event shall the arbitrators enlarge upon, or alter or amend, this
Lease or Lessor's or Lessee's rights as provided in this Lease, it being
understood that the sole issue for determination by the arbitrators shall be the
single issue of fact of the annual fair rental value of the Demised Premises as
provided in paragraph A of this Section 30.01.

     (4) Except as otherwise provided in the following sentence, the fees and
expenses of an arbitration proceeding shall be borne by the parties equally. 
The fees of respective counsel engaged by the parties the fees and expenses of
expert witnesses and other witnesses called and the cost of transcripts shall be
borne by the parties engaging such counsel or, calling such witness or ordering
such transcripts.

     SECTION 30.05. The rights provided to Lessee to extend this Lease as
provided in Section 30.01 is conditioned in all respects upon (i) there being no
Event of Default in the observance or performance of any term, covenant,
condition or agreement of Lessee's part to be observed or performed under this
Lease both at the time the notice of exercise is given and immediately prior to
commencement of the Renewal Term, and (ii) there being no sublease in effect
(other than subleases with related corporations) with respect to the Demised
Premises or any part thereof during the two (2) year period immediately
preceding the Expiration Date originally provided for herein.  Any termination,
cancellation or surrender of this Lease shall terminate any right of extension
hereunder for the Renewal Term.

                     ARTICLE 31 -   FIBER OPTIC NETWORK SERVICES

     SECTION 31.01. From and after the Commencement Date, Lessor agrees that
Lessee shall have the right, subject to the rights of other lessees, and
Lessor's reasonable consent, which shall not be unreasonably withheld,
conditioned or delayed, to install, maintain, repair, remove and operate in the
Demised Premises and penetrate the Building in a location reasonably designated
by Lessor and utilize existing Building conduits and risers for the installation
and maintenance of fiber optic cables, PROVIDED, HOWEVER, that such fiber optic
cables do not exceed four (4) inches in diameter, in connection with Lessee's
fiber optic network (the "Fiber Optic Network") for the Term of this Lease or
any Renewal Term.  Lessee shall notify Lessor of its intention to install, use
and maintain the Fiber Optic Network in accordance with the provisions of this
Lease.

     SECTION 31.02. If Lessor shall grant its consent to the installation, use
or maintenance of the Fiber Optic Network, then the same shall (i) be installed
and maintained at the sole cost and expense of Lessee, (ii) be installed and
maintained in a good and workmanlike manner, in a location reasonably designated
by Lessor, and in compliance with all applicable Legal Requirements (including
existing zoning requirements), Insurance Requirements and Environmental Laws,
(iii) be consistent with the use of the Demised Premises provided for herein,
(iv) be performed in accordance with plans and specifications approved prior to
the commencement of any work by the appropriate Governmental Authorities and by
Lessor, which approval by Lessor will not be unreasonably withheld, conditioned
or delayed, (v) be of such nature so as not to lessen the fair market value of
the Building or Property, and (vi) be performed under the supervision of a
licensed architect reasonably approved by Lessor and in accordance 
                                    Page 32 of 40
<PAGE>

with Lessor's STANDARD REQUIREMENTS FOR ALTERATIONS TO BE PERFORMED BY LESSEES,
as may be reasonably amended from time to time. 

     SECTION 31.03.A. Unless Lessor shall otherwise expressly indicate in
writing at the time of granting its consent to the installation of the Fiber
Optic Network, Lessee shall, on or before the expiration or sooner termination
of this Lease as and when provided in Section 29.02, remove the Fiber Optic
Network and restore the affected portion of the Demised Premises and Building to
the state or condition thereof existing prior to the installation of the Fiber
Optic Network.

     B. Any and all contractors to be involved in performing work shall be
subject to Lessor's prior approval, which shall not be unreasonably withheld,
conditioned or delayed.

     C. Prior to installing the Fiber Optic Network, Lessee shall furnish Lessor
with evidence reasonably satisfactory to Lessor of such insurance as Lessor may
require and such insurance shall be in full force and effect during such
installation and will cover, by endorsement or otherwise, the risk during the
course of such installation.

     SECTION 31.04. All of the terms, covenants and conditions of this Lease
shall continue in full force and effect.

     SECTION 31.05. The right of Lessee to install, use or maintain the Fiber
Optic Network as provided in Section 31.01 is conditioned in all respects upon
there being no material Event of Default in the observance or performance of any
term, covenant, condition or agreement on Lessee's part to be observed or
performed under this Lease both at the time the notice is given.  Any
termination, cancellation or surrender of this Lease shall terminate Lessee's
right to install, use or maintain the Fiber Optic Network.

                                 ARTICLE 32 - BROKERS

     SECTION 32.01. The parties represent that in connection with this Lease it
dealt with no broker other than Austin Corporate Properties, Inc. and
Insignia/ESG (the "Brokers"), nor has either party had any correspondence or
other communication in connection with this Lease with any other person who is a
broker, and that so far as the parties are aware the Brokers are the only
brokers who negotiated this Lease.  Each party hereby indemnifies the other
party and holds it harmless from any and all loss, cost, liability, claim,
damage, or expense (including court costs and attorneys' fees) arising out of
any inaccuracy of the above representation.  Lessor agrees to pay the Brokers
all commissions due for their services pursuant to a separate written agreement.

                            ARTICLE 33 - SECURITY DEPOSIT

     SECTION 33.01.A. Lessee shall deposit with Lessor, upon execution of this

vendee or lessee, and Lessor shall thereupon be released by Lessee from all
liability for the return of such cash security or Letter of Credit to a new
lessor, provided that such new lessor assumes all of Lessor's obligations with
respect to such cash security or Letter of Credit.  Lessee shall execute such
documents as may be necessary to accomplish such transfer or assignment of the
Letter of Credit.

     SECTION 33.04. Lessee covenants that it will not assign or encumber, or
attempt to assign or encumber the monies or Letter of Credit deposited hereunder
as security, and that neither Lessor nor its successors and/or assigns shall be

     SECTION 33.05. In the event that Lessee shall fully and faithfully comply
with all of the terms, provisions, conditions and covenants of this Lease, and
provided further, that no Event of Default shall have occurred and be

                              STANDARD REQUIREMENTS FOR
                        ALTERATIONS TO BE PERFORMED BY LESSEES

     For purposes of these STANDARD REQUIREMENTS FOR ALTERATIONS TO BE PERFORMED
BY LESSEES, Lessee's Alterations, as that term is defined in Article 8 of the
Lease, and Lessee's construction, work and alterations as contemplated in
Article 25 of the Lease are hereinafter sometimes collectively referred to as
the "Alterations."  Whenever in this Exhibit G Lessor's approval or consent must
be sought and obtained prior to the performance of any Alterations, such
approval or consent shall not be unreasonably withheld or delayed.

     SECTION 1.  All Lessee's Alterations shall be performed in accordance with
all Governmental Authority, Legal Requirements, Insurance Requirements and
Environmental Laws (as those terms are defined in the Lease) and other agencies
having jurisdiction and with the over-all design and construction standards of
the Building, Building Equipment and Demised Premises.  All Lessee's Alterations
shall be built in accordance with the provisions hereof, the Lease, and the
Final Plans (as hereinafter defined).

     SECTION 2.  All architectural and engineering plans and specifications for
the Demised Premises shall be prepared by a licensed architect employed by
Lessee at its sole cost and expense and shall describe all the work which under
this Lease is to be performed by Lessee and showing in sufficient detail the
location of all utilities, partitions, bathrooms, offices, storage and/or locker
facilities and any other matters which may affect the construction work to be

requested by Lessee or his architect and the actual cost thereof shall be born
by Lessee.

     SECTION 3.  It shall be the sole responsibility of Lessee and/or Lessee's
agent to file all drawings, plans and specifications, pay all fees and obtain
all permits and applications from all Governmental Authority having
jurisdiction, and to obtain a Certificate of Occupancy, Certificate of
Compliance and all other "sign offs" and approvals required to enable Lessee to
occupy the Demised Premises for the purposes provided for in its Lease.  Lessor,
at its sole cost and expense, shall be responsible for all violations in other
parts of the Building which prevent Lessee from obtaining the Certificate of
Occupancy, Certificate of Compliance and all other "sign offs" and approval to
enable Lessee to occupy the Demised Premises

     SECTION 4.  Simultaneously with any request for consent to make Lessee's
Alterations as defined in Article 8 of the Lease or alterations to the Demised

expense shall cause Lessee's architect to prepare and deliver to Lessor for
Lessor's approval two (2) sets of preliminary plans for Lessee's Alterations,
prepared in strict accordance with the provisions contained herein, initialed by
Lessee.  Lessor shall notify Lessee of the matters, if any, in which the
preliminary plans fail to conform to the standards established for the Property,
Building, Building Equipment and/or Demised Premises, or otherwise fail to meet
with the Lessor's approval.  Lessee shall promptly upon receipt of any such
notice or notices from Lessor cause the preliminary plans to be revised in such
manner as is requisite to obtaining Lessor's approval and shall resubmit said
revised preliminary plans initialed by Lessee as aforesaid for Lessor's approval
within Thirty (30) days of said notice.  When Lessor shall determine that the
preliminary plans are satisfactory to Lessor, Lessor shall cause one set thereof
to be initialed on behalf of Lessor, thereby evidencing the approval thereof by
the Lessor, and shall return such set so initialed to Lessee.  The preliminary
plans or revised preliminary plans, as the case may be, so approved by Lessor
are hereinafter referred to as the "Preliminary Plans."  If such Preliminary
Plans are not approved by Lessor within Fifteen (15) days after submission to
Lessor, Lessor shall advise Lessee of such disapproval and Lessee's architect
shall revise said plans at Lessee's cost and expense, and such plans shall be
deemed approved by both Lessee and Lessor.

     SECTION 5.  Within Thirty (30) days after Lessor's approval of Lessee's
Preliminary Plans, Lessee, at its sole cost and expense, shall cause to be
prepared and delivered to Lessor four (4) complete sets of drawings and
specifications showing Lessee's Alterations, prepared in conformity with
Preliminary Plans, and such drawings and specifications shall have been
initialed by Lessee, evidencing Lessee's approval thereof.  Lessor shall notify

of such notice from Lessor cause said drawings and specifications to be revised
in such manner as is requisite to obtaining Lessor's approval and shall resubmit
revised drawings and specifications initialed by Lessee as aforesaid for

     SECTION 5.01.  Licensor and Licensor's agents, officers, directors,

and from any and all liability, claims, suits, demands, judgments, costs,

proceeding shall be brought against Licensor by reason of any one or more
thereof, upon notice from Licensor, Licensee shall resist such action or
proceeding at Licensee's expense by counsel selected by Licensee and reasonably
satisfactory to Licensor.

     SECTION 8.01.  In the event Licensee ceases to be a tenant or occupant of
the Property, then in such event, this Parking Agreement shall automatically
terminate as of the date that Licensee ceases to be such tenant or occupant of
the Property.

     SECTION 9.01.  Licensee acknowledges that the monthly amount charged
pursuant to the terms and conditions of this Parking Agreement provided for in
Section 2 hereof is based on the current monthly rate of Seventy-Five ($75.00)
Dollars for each reserved space and Sixty-Five ($65.00) Dollars for each
non-reserved space.  Licensee agrees that such rates may, from time to time, be
increased by Licensor, with not less than thirty (30) days prior written notice
to Licensee, and such increased amount shall be paid by Licensee, and shall be
the greater of:  (a) the then current rate increased by an annual adjustment in

for the monthly rental of parking spaces as determined by comparison to similar
