OVERVIEW

    We are a growing Internet service provider offering Internet access and
enhanced services, such as web hosting, managed security solutions and other
value added products to small and medium sized enterprises through our regional
customer network facilities. We primarily offer our services in the mid-Atlantic
area of the United States and our strategy is to expand by replicating our
customer network facilities and our services offered to small and medium sized
enterprises in selected high growth secondary markets throughout the United
States. We have been providing Internet access services to our customers since
our incorporation in 1994. We supplement our dedicated Internet access services
with a comprehensive suite of enhanced products and services that are designed
to meet the expanding needs of our customers and increase our revenue per
customer. The services we provide include:

    - Internet access services;

    - Total Managed Security;

    - Web hosting services;

    - Internet applications hosting services;

    - Virtual private networks;

    - Unified messaging; and

    - Total managed backup and recovery services.

    Our customer network facility infrastructure and local sales support are
regionally located in order to provide cost savings to our customers and a high
quality of customer service. We intend to duplicate this network architecture in
targeted high growth secondary markets across the mid-Atlantic and northeastern
United States and, eventually, across the entire country.

    On July 30, 1999, we acquired Internet Unlimited, Inc., a web hosting and
colocation company. As of December 31, 1999, we provided Internet access and
enhanced products and services to approximately 300 enterprise customers, of
which approximately 275 were small and medium sized enterprises, and
approximately 15,800 dial-up customers in the mid-Atlantic area. We also provide
web hosting services to approximately 4,400 customers.

                                       1

OUR MARKET OPPORTUNITY

    OVERVIEW.  The Internet has become an important global medium enabling
millions of people to obtain and share information and conduct business
electronically. Its expanded use has made the Internet a critical tool for
information and communications for many users. Internet access and enhanced
Internet services, including web hosting and electronic commerce services,
represent two of the fastest growing segments of the telecommunications services
market. International Data Corporation estimates that at the end of 1998 there
were over 62 million web users in the United States and over 134 million
worldwide, and projects that by the end of 2003 the number of web users will
increase to 177 million in the United States and over 472 million worldwide. The
availability of Internet access, advancements in technologies required to
navigate the Internet, and the proliferation of content and applications
available over the Internet have attracted a rapidly growing number of Internet
users.

    GROWTH IN BUSINESS USE OF THE INTERNET.  The dramatic growth in Internet
usage in recent years, combined with enhanced functionality, accessibility and
security, has made the Internet increasingly attractive to businesses as a
medium for communication and commerce. For many businesses, the Internet has
created a new communication and sales channel which enables large numbers of
geographically dispersed organizations and consumers to be reached quickly and
cost-effectively. International Data Corporation estimates that the number of
consumers buying goods and services on the Internet will grow from 21.1 million
in 1998 to 72.1 million in 2003, and that the total value of goods and services
purchased over the Internet will increase from approximately $37 billion in 1998
to approximately $707 billion by 2002.

    Businesses are increasingly adding a variety of enhanced services and
applications to their basic Internet access, web sites and e-commerce
applications in order to more fully capitalize on the power of the Internet.
These services and applications allow them to more efficiently and securely
communicate company information, expand and enhance their distribution channels,
increase productivity through back-office automation, ensure reliability and
reduce costs.

    - DEMAND FOR INTERNET ACCESS SERVICES. The Internet continues to increase in
      size and importance as its role in integral business operations expands.
      Internet access services represent the means by which ISPs interconnect
      their customers to the Internet or corporate intranets and extranets.
      According to International Data Corporation, Internet access revenues from
      businesses are expected to more than double in the next four years from
      $5.1 billion in 1999 to $12 billion in 2003. Because small and medium
      sized enterprises often lack the technical capabilities and operational
      scale to implement their Internet operations, these enterprises often seek
      assistance from third-party service providers.

    - DEMAND FOR WEB HOSTING SERVICES. As Internet web sites become increasingly
      critical to businesses, many businesses are seeking to outsource to ISPs
      services such as web hosting, colocation and file transfer protocol data
      storage and retrieval.

    - DEMAND FOR SECURE PRIVATE NETWORKS. As businesses increasingly rely on the
      Internet for communication and commerce, concerns relating to the security
      of their internal and proprietary information, data loss and reduced
      transmission speed has led those businesses to demand Internet services
      that include the ability to provide electronic security monitoring and
      threat responses.

    THE SMALL AND MEDIUM SIZED ENTERPRISE MARKET.  We have specifically targeted
small and medium sized enterprises because:

    - We believe that these enterprises increasingly need high-speed data and
      Internet connections to access business information and to communicate
      more effectively with employees, customers, vendors and business partners.

                                       2

    - We believe that a relatively small percentage of these enterprises
      currently utilize the Internet, however, we believe the number of
      enterprises utilizing the Internet will increase rapidly. The small and
      medium sized enterprise segment is expected to be one of the fastest
      growing segments of the Internet industry. According to International Data
      Corporation, web-related expenditures by small businesses in the United
      States are expected to grow from $9.6 billion in 1999 to over $32 billion
      by 2003.

    - Many of these enterprises lack the resources and expertise to develop,
      maintain and expand, on a cost-effective basis, the facilities and network
      systems necessary for successful Internet operations.

    - These enterprises often prefer an Internet service provider with
      locally-based personnel who are available to assist in developing and
      implementing their growing use of the Internet and to respond to technical
      problems in a timely manner.

    - We believe that these enterprises rely more heavily on their Internet
      service provider than larger enterprises.

    INTERNET SERVICES IN SECONDARY MARKETS.  Small and medium sized enterprises
are often concentrated in secondary markets to avoid the higher costs associated
with locating in a metropolitan area. We define a secondary market as typically
smaller than the 100 most populated U.S. metropolitan markets. However, national
ISPs have historically placed their largest points of presence, only in or
around densely populated major cities. Customers that are located within a few
miles from these points of presence often receive cost savings on their access
pricing. However, customers located in secondary markets that are 20 to 75 miles
away from these points of presence have typically been charged higher prices for
Internet access services.

    We believe that small and medium sized enterprises located in high growth
secondary markets are currently underserved by both national and local providers
of Internet access and related services. National ISPs typically lack the local
presence to provide local support. Local ISPs, on the other hand, often lack the
requisite scale and resources to provide a full range of services at acceptable
quality and pricing levels.

OUR SOLUTION

    We believe that we offer our customers a comprehensive solution to their
Internet access and enhanced products and services needs. Key aspects of our
solution include:

    TECHNOLOGY PLATFORM.  Our network architecture is designed around customer
network facilities that we construct in each region in which we operate. As of
March 24, 2000 we had eleven customer network facilities in operation. A
customer network facility is a high capacity data center that provides our
customers with redundant connections to the Internet through connections to not
less than two independent Internet backbone networks. This assures our customers
of fewer delays in accessing the Internet and continued service should one of
the backbone networks fail. In addition, our customer network facilities feature
redundant power and climate control systems, and are continuously monitored
through a connection to our network operations center. This connection allows us
to monitor and control regional customer network facility operations
24 hours-a-day, 7 days a week, which allows our staff to be immediately alerted
and responsive to problems as they arise. This control of our network
infrastructure also allows us to improve quality of service by minimizing
network downtime. The network operations center also provides an additional
level of redundancy of Internet connectivity. In the event that both independent
Internet backbone networks to which a customer network facility is connected
fail, customer traffic can be routed to the Internet through the network
operations center to minimize service interruptions. Likewise, a customer
network facility will continue to function even if its connection to the network
operations center fails.

                                       3

    COMPREHENSIVE SUITE OF SERVICES.  We seek to provide small and medium sized
enterprises with a single source for their Internet service needs. Our
comprehensive suite of services enables our customers to easily and more
cost-effectively address their Internet needs without developing solutions
internally or assembling services from multiple vendors, including resellers,
other Internet service providers and information technology service providers.
We offer our services in customized bundles through a single network connection
and provide our customers with technical support and management expertise.

    HIGH QUALITY CUSTOMER SUPPORT AND SERVICE.  We focus on providing our
customers with high quality support and service in order to maintain customer
loyalty and maximize retention. Our focus on regional marketing and regional
network access enables us to provide the personalized service and attention that
small and medium sized enterprises often require. In addition, we believe that
customer satisfaction is critical to our success in selling our enhanced
products and services. We provide around-the-clock customer support, real-time
monitoring of all circuits and services and high quality customer service.

    PLUG AND PLAY EASE OF INSTALLATION.  In order to simplify what is sometimes
a technically challenging installation, we have designed and continue to enhance
our products and services to provide our customers with plug and play
installation. We ship pre-configured equipment to our customers that, in most
cases, is ready for installation. In the event that a customer requires
assistance, the customer can contact our engineering installation department,
where the customer is guided through the installation process at no additional
charge. In addition, many of our enhanced products and services require no
additional hardware and can be installed through the customer's existing
connection to our customer network facility.

    COST SAVINGS TO OUR CUSTOMERS.  We believe our Internet solutions are more
cost-effective for our customers than developing their own in-house Internet
solutions. In order to match the level of performance and reliability that we
provide to our customers, they would need to make significant expenditures for
equipment, personnel and dedicated bandwidth. In addition, they would need to
develop Internet expertise and would be required to divert resources from their
primary business activities.

    We believe that we can continue to provide high quality Internet services to
small and medium sized enterprises because we have developed a cost-effective
and highly efficient regional strategy that enables us to eliminate many of the
high cost network transport and interconnect elements typically associated with
a national network. A national network is commonly designed to include a point
of presence, or Internet access point, which enables a customer to connect to
one or more peering points. These peering points enable national networks to
connect with other networks to access the Internet for their customers. National
network customers connect to a point of presence then to a peering point through
large and typically expensive data circuits owned by the national network. Our
regional network design reduces the high costs associated with a national
network structure by eliminating the need for us to invest capital to purchase
large expensive data circuits. Instead, our network delivers the data from the
customer directly to the primary backbone provider which requires less expensive
circuits that connect our regionally located customer network facilities to our
main network operations center. In addition, because we position our customer
network facilities close to secondary markets, we often are able to utilize
shorter circuits than those used by national providers and do not need to rely
on national or international transport circuits, which are generally higher cost
than regional circuits. Furthermore, because our customer network facilities
support only our data products, we do not incur expenses related to telephony
equipment, long-distance switches and other voice services.

                                       4

OUR STRATEGY

    Our goal is to be the premier provider of Internet access and enhanced
Internet products and services to small and medium sized enterprises in our
target markets. Key elements of our strategy include:

    REPLICATING OUR MODEL RAPIDLY IN SELECTED SECONDARY MARKETS.  We intend to
continue expanding into selected high growth secondary markets by replicating
our regional network and marketing model. Our network architecture and scalable
sales and marketing plan are designed to allow us to penetrate additional
regions rapidly and cost-effectively. In the past, we have been able to provide
limited services to customers within 90 days after the start of construction of
a new customer network facility. By focusing on smaller regions, we are able to
build our regional networks more quickly than if we were to build a contiguous
national network. Our customer network facilities are modular and use
non-proprietary standards-based equipment that can be obtained from multiple
vendors. This allows for a simpler design, easier duplication and cost savings.
We also implement a flexible marketing model in each region that addresses the
particular product and service needs of our target customers in that region. In
order to successfully replicate our model in our target regions, we must:

    - IDENTIFY ATTRACTIVE REGIONS. We target regions that are typically growing
      rapidly and have a large concentration of small and medium sized
      enterprises. Our focus has been on regions outside of major metropolitan
      cities located in the mid-Atlantic area of United States. We intend to
      expand throughout the mid-Atlantic United States and enter into target
      regions in the northeastern United States and, eventually, throughout the
      entire country.

    - RAPIDLY BUILD ADDITIONAL CUSTOMER NETWORK FACILITIES. Our network
      architecture is easily replicated in each target region. Each of our
      customer network facilities requires virtually the same equipment,
      physical space and redundancy regardless of the region. As a result, we
      can pre-fabricate many of the elements required to deploy a customer
      network facility and also take advantage of volume pricing for our
      equipment.

    - CONTINUE OUR HIGHLY FOCUSED SALES AND MARKETING EFFORTS. We have
      established a sales and marketing strategy based upon a centralized sales
      staff with active local support. We will continue to market our products
      and services in our target regions through a combination of highly focused
      local advertising, brand awareness campaigns and a focused sales effort.
      We tailor our marketing efforts to each region to utilize the most
      cost-effective methods of advertising and to address local preferences. As
      a result, we generally do not incur the significant expenses related to
      broad-based national media and advertising campaigns.

    EXPANDING CUSTOMER RELATIONSHIPS TO MARKET ENHANCED SERVICES.  We offer a
portfolio of enhanced products and services to meet the expanding needs and
complexity of our customers' Internet operations. We market these products and
services to our existing customers to increase revenues per customer and
maintain high customer retention by strengthening our customer relationships.

    USING CENTRALIZED SALES AND MARKETING OPERATIONS TO EXPAND OUR REGIONAL
SALES AND MARKETING BY TAKING ADVANTAGE OF ECONOMIES OF SCALE. We use our
centralized sales and marketing staff to help implement our regional strategy
cost-effectively. We intend to hire and train additional local sales and
marketing personnel within our target regions to compliment the core of our
sales and marketing staff which will continue to be concentrated in one
centralized location to maximize efficiency. These regionally located employees
add local market knowledge, expertise and familiarity to our sales and marketing
efforts. This allows us to maintain a field presence in each of our regions,
while maximizing the utilization of our central operations, where the majority
of our employees are located.

    ENTERING INTO STRATEGIC RELATIONSHIPS AND MAKING SELECTED ACQUISITIONS.  We
seek to enter into strategic relationships with third party vendors to develop
and obtain new technologies to incorporate into our

                                       5

product and service offerings. We believe that this enables us to meet our
customers' needs efficiently and in a cost-effective manner. For example, as
part of our relationship with WatchGuard Technologies, Inc., we worked with
WatchGuard to modify their security product to meet customers' needs.
Additionally, we have recently entered into an agreement with Covad
Communications Company to sell Covad's DSL services to our customers.

    We recently entered into an equipment lease arrangement with Lucent
Technologies, Inc. and acquired Internet Unlimited, Inc., a provider of web
hosting and colocation services. We intend to make strategic acquisitions that
enable us to offer additional enhanced products and services to our customers.
We may also enter into strategic relationships with third-party service
providers to enable them to deliver their Internet products and services
directly to our customers.

SALES AND MARKETING

    As of December 31, 1999 we employed 29 sales and marketing professionals at
our corporate headquarters. This group comprises our centralized sales and
marketing team and is responsible for contacting potential and existing
customers within each region. Our sales team also works with our regional
marketing managers to offer enhanced products and services to existing customers
and ensure overall customer satisfaction. In order to maximize the efficiency of
our sales process, we have developed a uniform set of sales procedures which our
sales staff has been trained to implement.

    We use targeted marketing and media advertising to develop brand awareness
and supplement these efforts with our highly customized sales process and
personalized customer service. Through our regional marketing managers, we seek
to develop strong customer relationships within local communities.

    Our regional marketing managers also provide assistance and support to our
centralized sales staff. This enables us to evaluate customers' needs more
effectively, to design customized solutions and to reinforce our local presence
as a value-added provider of enhanced Internet services. Our regional marketing
managers also identify market trends, provide constant data regarding changes in
the competitive landscape and also may identify and initiate contact with new
customers. In addition, our regional marketing managers attend trade shows and
Chamber of Commerce events, as examples, to further reach the targeted small and
medium sized enterprises in each region.

    We also maintain a web site at WWW.FAST.NET, which provides Internet users
information about us and the opportunity to obtain answers to some frequently
asked questions. Through our web site, customers can also learn how to obtain
Internet access and enhanced products and services through a FASTNET connection.

PRODUCTS AND SERVICES

    We offer a comprehensive Internet solution to our customers, which includes
dedicated and dial-up Internet access and enhanced Internet products and
services. Our dedicated Internet access offering is available at speeds that
range from 56 kilobits per second to 45 megabits per second. Dedicated Internet
access can be delivered through standard telephony circuits, such as T-1 through
T-3 digital circuits, digital subscriber line technology, also known as DSL, or
wireless connections. We offer our customers DSL service through an agreement
with Covad Communications Company which enables us to sell Covad's DSL service
as a bundled package with our Internet access and other value added services.
Our dedicated Internet access provides our customers with always-on connectivity
to the Internet as well as access to our enhanced Internet products and
services. In addition, we offer dial-up Internet access to customers, which
provides lower cost, lower bandwidth connectivity to the Internet. To ensure
maximum availability and reliability of our products and services, our
facilities feature backup power and redundant bandwidth.

                                       6

    In addition to Internet access, we offer a suite of enhanced Internet
products and services to our customers. As the needs of our customers evolve, we
will add to and modify existing product and services offerings to meet the needs
of our customers. Our current enhanced services include:

    - TOTAL MANAGED SECURITY SERVICES--We address our customers' concerns about
      the security of data transmitted over the Internet by offering various
      levels of protection through our Total Managed Security services. These
      services provide security to a company's network, including local area
      networks and wide area networks, from unauthorized access by external
      sources. In addition, as part of our services, our network operations
      center personnel provide 24 hours-a-day, seven days-a-week monitoring and
      threat response. We incorporate third-party products into our security
      solution and we continually evaluate third-party products to meet the
      future needs of our customers. These products include web content
      filtering, mail filtering and detailed log file generation. On
      December 30, 1998, we entered into a Managed Security Services Agreement
      with WatchGuard Technologies, Inc. to provide these security services and
      products, which expires on December 31, 2000. This agreement renews for an
      additional one-year term if we meet or exceed minimum quarterly purchase
      amounts and neither party has provided the other party notice of its
      intention not to renew the agreement at least 30 days prior to the end of
      the applicable term. Under the terms of this agreement, we have agreed to
      purchase a minimum annual amount of services and products from WatchGuard,
      resulting in minimum payments to WatchGuard of approximately $274,000 per
      year.

    - WEB HOSTING SERVICES--We provide a wide range of content hosting services,
      including shared and dedicated hosting on our servers for customer web
      sites as well as colocation hosting of customer supplied servers in our
      facilities. Entry level shared server web hosting provides our customers
      with a managed and pre-configured system at a reasonable cost. The
      customer simply adds its content through an interface such as FTP (file
      transfer protocol) or, in a growing number of cases, through Microsoft's
      FrontPage extensions. Server colocation allows customers to place their
      own servers within our facilities. Upon request, we can sell servers to
      the customer and maintain them for an additional fee.

    - INTERNET APPLICATIONS HOSTING SERVICES--The growth of the Internet has
      made a strong web presence increasingly important for small and medium
      sized enterprises. We provide our customers with the Internet applications
      hosting services they need to remain competitive. Our Internet
      applications hosting services include e-commerce services and other
      sophisticated applications related to the operation of an e-commerce
      enabled web site. Our Internet applications hosting services work in
      conjunction with our web hosting services to provide our customers with a
      comprehensive web presence.

    - VIRTUAL PRIVATE NETWORK SERVICES--When an enterprise customer wants to
      enable remote or off-site access to its computer network, the enterprise
      commonly uses a form of a virtual private network connection. A virtual
      private network provides a convenient and secure computer connection from
      a remote location back to the company's main computer network. We provide
      customers with our CC/vpn product, which enables them to control many
      aspects of their configuration, such as user profile changes and security
      functions, through a private web-based interface.

    - UNIFIED MESSAGING SERVICES--The Internet has been the catalyst for a
      variety of convenient web-based communications services, such as e-mail,
      computer-based faxing and paging. In many cases, each of these services
      requires the user to access individual applications to view messages.
      Unified messaging combines messaging services and allows a user to view
      all messages through one application. We provide our customers with a user
      friendly unified messaging service that is based on Internet protocol
      standards. We believe that we will be able to offer our unified

                                       7

      messaging services in the future with enhancements such as voicemail and
      other multimedia tools.

    - TOTAL MANAGED BACKUP AND RECOVERY SERVICES--We provide Internet-enabled
      backup and recovery services for a company's data network through off-site
      data and storage. We believe that many small and medium sized businesses
      lack a scheduled computer data back-up routine, which may leave them
      vulnerable to data loss. Our total managed backup and recovery product is
      simple to use and can be easily installed on most servers and desktop
      computers. By using this service, our customers can schedule automatic
      data back-ups to our servers located within our network. Typically, the
      customer accesses our server over the customer's connection to our
      customer network facility. In most cases, this eliminates the need for the
      customer's data to be transmitted over the Internet. For a further level
      of security, we encrypt the customer's data before transmission to the
      storage servers, where it remains in a secret encrypted form. These total
      managed backup and recovery services effectively provide our customers
      convenient and secure off-site storage of their data.

    We have agreements with our customers for our services that are typically
for a one year term that after expiration will automatically convert to a
monthly term until the agreement is either terminated upon 30 days notice or
renewed for a new one year term. We bill our customers on a monthly basis and in
some circumstances we offer discounts for prepayment. We offer each of our
services individually or as part of a bundled solution. Our customers receive
additional discounts from us if they purchase more than one service.

NETWORK ARCHITECTURE AND INFRASTRUCTURE

    Our network architecture is designed to provide our customers with reliable,
high speed Internet access as well as our comprehensive suite of enhanced
products and services. Key components of our network are:

    CUSTOMER NETWORK FACILITY.  The core of each of our regional networks is the
customer network facility. Each customer network facility is designed to operate
as a stand-alone, self-contained Internet services facility capable of
supporting our full range of products and services to meet the needs of our
customers in each region. We provide our dedicated access customers with
constant Internet access through a data circuit that is connected continuously
to the Internet by way of a customer network facility. Dedicated access
customers in each region connect to one of our customer network facilities using
high speed data circuits provided by an incumbent local exchange carrier or
competitive local exchange carrier. An incumbent local exchange carrier is
generally the original telephone company which services the customer's area. A
competitive local exchange carrier is generally a company that is trying to
compete with an incumbent local exchange carrier. Our dial-up customers connect
to our network using either 56K modem or digital ISDN circuits. We subscribe on
a monthly basis for services provided by a number of local exchange carriers,
including AT&T Corporation, through its subsidiary Teleport Communications
Group, and Bell Atlantic Corporation. We also have agreements with local
exchange carriers, including the following companies:

    - HYPERION COMMUNICATIONS OF NEW JERSEY, LLC. We entered into an agreement
      with Hyperion on May 12, 1999 for a term of one year. Hyperion provides us
      with local exchange, switched access, long distance and dedicated access.
      Under the terms of this agreement, we have agreed to purchase a minimum
      annual amount of services from Hyperion, resulting in minimum payments to
      Hyperion of approximately $242,000 per year.

    - NEXTLINK PENNSYLVANIA, INC. We entered into agreements with NEXTLINK in
      June, October and December 1999, each for a term of three years. NEXTLINK
      provides us with point-to-point DS3 service. Under the terms of these
      agreements, we have agreed to purchase a minimum

                                       8

      annual amount of services from NEXTLINK, resulting in minimum payments to
      NEXTLINK of approximately $327,000 per year.

    Each customer network facility has access to at least two Internet backbone
providers. We have agreements with a number of national Internet backbone
providers, including the following companies:

    - MCI WORLDCOM INC. We entered into an agreement with MCI on August 6, 1999
      for a term of three years. MCI provides us with DS3 private line service.
      Under the terms of this agreement, we have agreed to purchase a minimum
      annual amount of services from MCI, resulting in minimum payments to MCI
      of approximately $180,000 per year. This agreement is renewable on a
      month-to-month basis.

    - UUNET TECHNOLOGIES, INC. We entered into agreements with UUNET, one in
      August 1999 for a one year term and another in December 1999 for a three
      year term. UUNET provides us with T3 and T1 service. Under the terms of
      these agreements, we have agreed to purchase a minimum annual amount of
      services from UUNET, resulting in minimum payments to UUNET of
      approximately $669,000 per year. These agreements may be terminated by
      either party upon 60 days advance notice to the other party, without
      obligation or penalties for further payments.

    - SPRINT COMMUNICATIONS COMPANY, L.P. We entered into an agreement with
      Sprint on June 8, 1999 for a term of three years. Sprint provides us with
      dedicated Internet access service. Under the terms of this agreement, we
      have agreed to purchase a minimum annual amount of services from Sprint,
      resulting in minimum payments to Sprint of approximately $1.4 million per
      year.

    These services provide redundancy and high reliability in the event that any
of our backbone providers should experience network difficulties. We are billed
by all of our backbone providers monthly and are generally charged according to
the number of services that we choose to subscribe to in addition to initial
installation fees. Since we maintain a carrier-independent design, we have the
flexibility to select the most reliable and lowest cost provider in each region.

    NETWORK OPERATIONS CENTER.  Each customer network facility is connected to
our network operations center. The network operations center monitors the
operation of each device connected to our network and provides instantaneous
notification of any faults or failures. This monitoring process is designed to
ensure that we are in position to react quickly to restore operations in the
event of technical problems. In addition, the connection between the network
operations center and the customer network facilities provides an additional
level of redundancy for customer traffic if needed. Once each customer network
facility is connected to the Internet independently from the network operations
center, connections from a customer network facility to the network operations
center typically do not require the same expensive high capacity or high
bandwidth transport facilities that link customer network facilities to the
Internet. As a result, we reduce our costs of backbone transport.

    EQUIPMENT.  We purchase our equipment from a number of vendors to take
advantage of beneficial pricing and improvements in technology and performance.
We currently use routers from Cisco Systems, Inc., such as the 7500 series, that
are equipped with redundant components including route switching processors and
power supplies for added reliability. We sell both Cisco Systems, Inc. and
Nortel Networks Corporation (Bay Networks) routers to our customers for use as
customer premise equipment. We entered into an Equipment Lease Agreement with
Bay Networks on May 29, 1997 for a term of three years. Under the terms of this
agreement, we have agreed to make minimum payments to Bay Networks of
approximately $31,000 per year. This agreement is renewable on a month-to-month
basis. We entered into a Master Lease Agreement with Cisco Systems on
November 3, 1999 for a term of three years. Under the terms of this agreement,
we have agreed to lease equipment from Cisco Systems, resulting in minimum
payments to Cisco Systems of approximately $235,000 per year. Our dial-up
Internet access, as well as our virtual private network services for 56K analog
and 128K ISDN, use Lucent Technologies (Ascend) TNT remote access servers. On
September 18, 1998

                                       9

and June 29, 1999 we entered into Master Lease Agreements for equipment leasing
with Lucent Technologies (Ascend), each having three year terms. Under the terms
of one of these agreements, we have agreed to lease equipment from Lucent,
resulting in minimum payments to Lucent of approximately $34,000 per year. Under
the terms of the second agreement, we have a credit line to finance the leasing
of additional equipment. We have the option to purchase the equipment subject to
these leases at the end of the lease term and, in some cases, renew the term of
the lease for an additional rental period. Our networks also utilize and rely on
switches, hubs and other connection devices, which we purchase from a number of
different manufacturers. Our enhanced products and services are supported by Sun
Microsystems, Inc. UNIX-based and Microsoft Windows NT-based servers located at
our customer network facilities.

    PEERING ARRANGEMENTS.  Peering is the act of exchanging data across
networks, typically at specific, defined locations. Peering allows traffic from
one network to be delivered to an address located on another network. In
general, our contracts with our Internet backbone providers include peering
arrangements at the public peering points on the Internet. We may decide in the
future to supplement these public peering arrangements with private peering
agreements with other service providers if we determine that these would improve
our service and provide economic and/or technological benefits.

CUSTOMERS

    Our customer base consists primarily of small and medium sized enterprises
and dial-up customers located in high growth secondary markets. As of
December 31, 1999, we provided Internet access and enhanced services to
approximately 300 enterprise customers, of which approximately 275 were small
and medium sized enterprises, and approximately 15,800 dial-up customers in the
mid-Atlantic area. We also provided web hosting services to approximately 4,400
customers. While we have not concentrated our sales and marketing efforts on
Fortune 500 companies, we provide our Internet solutions to a number of large
enterprises. Lucent Technologies, Inc. accounted for 7% of total revenues for
the year ended December 31, 1999 and 11% of total revenues for the fiscal year
ended December 31, 1998 and Microsoft's WebTV Networks, Inc. accounted for 21%
of total revenues for the year ended December 31, 1999 and 9% of total revenues
for the fiscal year ended December 31, 1998. We expect that a significant
portion of our revenues will continue to be derived from a limited number of
customers which may vary from year to year.

CUSTOMER AND TECHNICAL SUPPORT

    We believe superior customer and technical support is critical to our
ability to retain existing customers and attract new customers. Our customers
depend on the speed and reliability of our network and our ability to keep them
connected to the Internet at all times. The knowledge and service orientation of
our local customer and technical support personnel are key elements in our
ability to assist our customers in quickly resolving their problems.

    To address individual customer problems, we provide customer technical
support 24 hours-a-day, seven days-a-week. Our customers also have the ability
to reach our customer support representatives by e-mail or schedule a telephone
appointment at a time that is convenient to them. In addition, our local
customer representatives are available to respond to individual customer needs
and provide direct customer support within their designated area. Our strategy
of creating a partnership between local support teams and a central call center
enables us to capture economies of scale, improve quality and responsiveness and
increase productivity, while allowing local personnel to focus on relationships
with customers.

                                       10

COMPETITION

    The Internet services market is extremely competitive and highly fragmented.
We face competition from numerous types of ISPs, including national ISPs, and
anticipate that competition will only intensify in the future as the ISP
industry consolidates. We believe that the primary competitive factors in the
Internet services market include:

    - pricing;

    - quality and breadth of products and services;

    - ease of use;

    - personal customer support and service; and

    - brand awareness.

    We believe that we have competed favorably based on these factors,
particularly due to our:

    - regionally focused operating strategy;

    - superior customer support and service; and

    - high performance.

    Our current competitors include many large companies that have substantially
greater market presence, brand-name recognition and financial resources. Some of
our local or regional competitors may also enjoy greater recognition within a
particular community. We currently compete, or expect to compete, with the
following types of companies:

    - national Internet service providers, such as PSINet, Inc. and Concentric
      Network Corporation;

    - providers of web hosting, colocation and other Internet-based business
      services, such as Verio, Inc.;

    - numerous regional and local Internet service providers, some of which have
      significant market share in their particular market area;

    - established on-line service providers, such as America Online, Inc.;

    - computer hardware and other technology companies that provide Internet
      connectivity with their own or other products, including the International
      Business Machines Corporation and Microsoft Corporation;

    - national long distance carriers such as AT&T Corporation, MCI
      WorldCom, Inc., Qwest Communications International Inc. and Sprint
      Communications Company, L.P.;

    - regional Bell operating companies and local telephone companies;

    - providers of free Internet service, including NetZero, Inc. and MicroWorkz
      Computer Corporation

    - cable operators or their affiliates, including At Home Corporation and
      Time Warner Entertainment Company, L.P.;

    - terrestrial wireless and satellite Internet service providers; and

    - nonprofit or educational ISPs.

    Many of the major cable companies and some other Internet access providers
have begun to offer or are exploring the possibility of offering Internet
connectivity through the use of cable modems. Cable companies, however, are
faced with large-scale upgrades of their existing plant, equipment and

                                       11

infrastructure in order to support connections to the Internet backbone via
high-speed cable access devices. We believe that there is a trend toward
horizontal integration through acquisitions or joint ventures between cable
companies and telecommunications carriers. Other alternative service companies
have also announced plans to enter the Internet connectivity market with various
wireless terrestrial and satellite-based service technologies. In addition,
several competitive local exchange carriers and other Internet access providers
have launched national or regional digital subscriber line programs providing
high speed Internet access using the existing copper wire telephone
infrastructure. Several of these competitive local exchange carriers have
announced strategic alliances with local, regional and national service
providers to provide broadband Internet access. These developments could harm
our business.

    Recently, several national access providers have begun offering dial-up
Internet access for free or at substantial discounts to prevailing rates, which
may result in significant pricing pressure for dial-up Internet access services.
We also believe that manufacturers of computer hardware and software products,
media and telecommunications companies and others will continue to enter the
Internet services market, which will intensify competition, especially for
dial-up access providers.

GOVERNMENT REGULATION

    We provide Internet access, in part through transmissions over public
telephone lines. These transmissions are governed by regulations and policies
establishing charges, terms and conditions for communications. As an Internet
provider, we are not currently regulated directly by the Federal Communications
Commission or any other agency, other than regulations applicable to businesses
generally. We could, however, become subject to regulation by the Federal
Communications Commission and/or other regulatory agencies if we become
classified as a provider of basic telecommunications services. These regulations
could affect the charges that we pay to connect to the local telephone network
or for other purposes. For example, Internet access providers, unlike long
distance telephone companies, currently are not required to pay carrier access
charges. Access charges are assessed by local telephone companies on
long-distance companies for the use of the local telephone network when the
local telephone company originates and terminates long-distance calls, generally
on a per-minute basis. The payment of access charges has been a matter of
continuing dispute, with long-distance companies complaining that the charges
are substantially in excess of actual costs and local telephone companies
arguing that access charges are justified to subsidize lower local rates for end
users and other purposes. In May 1997, the Federal Communications Commission
reaffirmed its decision that Internet access providers should not be required to
pay access charges and subsequent statements issued by the Federal
Communications Commission have not altered this conclusion. A requirement by the
Federal Communications Commission that we pay access charges could have a
significant impact on our costs of providing service.

    The Federal Communications Commission also has concluded that Internet
access providers should not be required to contribute to a new universal service
fund established to replace current local rate subsidies and to meet other
public policy objectives, such as providing access to enhanced communications
systems for schools, libraries and health care providers. As a result, unlike
other telecommunications providers, Internet access providers do not have to
contribute a percentage of their revenues to the federal universal service fund
and are not expected nor required to contribute to similar funds being
established at the state level. Both the access charge issue and the universal
service treatment of Internet access providers, however, are the subjects of
Federal Communications Commission proceedings and could change. Telephone
companies are actively seeking reconsideration or reversal of the relevant
Federal Communications Commission decisions and their arguments are gaining
support as Internet-based telephony begins to compete with conventional
telecommunications services. We cannot predict how these matters will be
resolved but we could be adversely affected if, in

                                       12

the future, Internet service providers are required to pay access charges or
contribute to universal service support.

    In addition, to the extent that an end user's call to an Internet access
provider is considered local rather than long distance, the local telephone
company that serves the Internet service provider may be entitled to reciprocal
compensation from the calling party's local telephone company. Reciprocal
compensation is a reimbursement mechanism between telephone companies whereby
the carrier that terminates a call is eligible for payment from the carrier
serving the calling party. This payment of reciprocal compensation reduces the
local telephone company's costs and ultimately reduces the internet service
provider's costs. However, the Federal Communications Commission recently
determined that most, but not all, traffic to an Internet access provider is
interstate rather than local in nature. This determination could potentially
eliminate the payment of reciprocal compensation to the local telephone
companies that serve us, which ultimately may affect our costs. There is a
pending proceeding at the Federal Communications Commission to determine
appropriate compensation mechanisms for such calls and the Federal
Communications Commission has ruled that state commissions, in the interim, may
determine under what circumstances reciprocal compensation should be paid. To
date, most states considering the issue have upheld reciprocal compensation for
calls placed to Internet service providers. If new compensation mechanisms
increase the costs to carriers that terminate calls to Internet service
providers or if states eliminate reciprocal compensation payments for calls to
Internet service providers, the affected carriers could increase the price of
service to Internet service providers to compensate themselves which could have
a material adverse effect on our business, financial condition and results of
operation.

    The Federal Communications Commission is also considering measures that
could stimulate the development of high-speed telecommunications facilities and
make it easier for operators of these facilities to obtain access to customers
by requiring incumbent telephone companies to provide access to their
rights-of-way and wiring located within multiple tenant buildings. In addition,
the Federal Communications Commission is considering requiring owners of
multiple tenant buildings to provide competing service providers
nondiscriminatory access to their buildings. Such regulatory measures could
enhance the competitive viability of Internet service providers that are
affiliated with the providers of these high-speed facilities.

    Finally, the issue of Internet service provider access to the infrastructure
deployed by cable television operators is under consideration at the local and
federal levels. Several municipal franchising authorities have required
franchised cable companies to provide competing Internet service providers open
access to their cable infrastructure. However, the Federal Communications
Commission has recently filed a brief in federal court addressing the open
access issue in which it voiced its opposition to such local regulation,
preferring instead a uniform national policy on the issue of open access. Also,
an ISP has recently sought a ruling from the Federal Communications Commission
that, pursuant to Section 612 of the Communications Act, cable operators should
be required to lease to competitors a 6 MHz channel to be used to provide
Internet services. Section 612 of the Communications Act requires cable
operators to provide leased access to competitors seeking to provide video
service. The Internet service provider seeking this Federal Communications
Commission ruling claims that almost all Internet services involve video
services, such as streaming technology, and therefore qualify for leased access
rights under Section 612. The outcome of these efforts to compel open access and
leased access will affect our business, by either increasing or foreclosing
Internet service provider access rights to the cable television infrastructure.

    The law relating to the liability of Internet service providers and online
service providers due to information disseminated through their networks is not
completely settled. While the U.S. Supreme Court has held that content
transmitted over the Internet is entitled to the highest level of protection
under the U.S. Constitution, there are federal and state laws regarding the
distribution of obscene, indecent, defamatory or otherwise illegal material, as
well as materials that infringe on intellectual

                                       13

property rights, that may subject us to liability. These risks are mitigated by
two federal laws. In 1996, Congress immunized Internet service providers and
online service providers from liability for defamation and similar claims
arising from materials the Internet service providers and online service
providers did not create, but merely distributed without knowing or having had
reason to know of their defamatory nature. Likewise, in 1998, Congress created a
safe harbor from copyright infringement liability for Internet service providers
and online service providers arising from materials placed on the Internet
service provider's or online service provider's network by third parties, so
long as basic requirements are satisfied.

    Due to the increasing popularity and use of the Internet, it is possible
that additional laws and regulations may be adopted covering issues such as the
sale of alcohol and firearms, content, user privacy, pricing and trademark or
copyright infringement. Laws and regulations potentially affecting us have been
adopted, and may be adopted in the future, by federal and state governments, as
well as by foreign governments. We cannot predict the impact, if any, that
recent and future legislative or regulatory changes or developments may have on
our business, financial condition and results of operations. Changes in the
regulatory environment relating to the Internet access industry, including
regulatory changes that directly affect telecommunications costs or increase the
likelihood or scope of competition from regional telephone or other companies,
such as open access to cable infrastructure, could have a material adverse
effect on our business.

INTELLECTUAL PROPERTY

    We have proprietary rights to trade secrets relating to technical and
business aspects of our operations. We have sought and will continue to seek
federal, state and local protection for these proprietary rights. We rely on a
combination of copyright, trademark and trade secret laws to protect our
proprietary rights, particularly those related to our names and logos. We
require each of our employees to enter into an inventions agreement, pursuant to
which each agrees that any intellectual property rights developed while in our
employment belong to us. We believe that we were the first to adopt the service
mark FASTNET and the associated logo in connection with Internet service
business, and have received federal registrations for them. In addition, we have
registrations pending for the following other names and marks: YOU'RE HUMAN, SO
ARE WE; 123HOSTME.COM; 123HOSTME! and HOST ME! We currently believe that these
names and marks are not material to our business.

    In connection with the delivery of some of our services, we bundle third
party software in our products for customers using personal computers operating
on the Microsoft Windows or Apple Macintosh platforms. While some of the
applications included in our start-up kit for access services subscribers are
shareware that we have obtained permission to distribute or that are otherwise
in the public domain and freely distributable, other applications included in
the start-up kit have been licensed where necessary. We currently intend to
maintain or negotiate renewals of all existing software licenses and
authorization as necessary, although we cannot be certain that such renewals
will be available to us on acceptable terms, if at all. We may also enter into
additional licensing agreements in the future for other applications.

EMPLOYEES

    As of December 31, 1999, we had a total of 91 employees, including 88
full-time employees and three part-time employees. Of these employees, 19 people
were in engineering, 43 people in general and administrative positions,
including executives, customer support, facilities-based transport and
accounting/billing and 29 people in sales and marketing.

    We are not a party to any collective bargaining agreements covering any of
our employees, have never experienced any material labor disruption and are
unaware of any current efforts or plans to organize our employees. We consider
our relationships with our employees to be good.

                   FACTORS AFFECTING FUTURE OPERATING RESULTS

    This annual report on Form-10-K contains forward-looking statements
concerning the Registrant's future products, expenses, revenue, liquidity and
cash needs as well as the Registrant's plans and strategies. These
forward-looking statements are based on current expectations and the Registrant
assumes no obligation to update this information. Numerous factors could cause
actual results to differ significantly from the results described in these
forward-looking statements, including the following risk factors.

WE ONLY RECENTLY BEGAN TO IMPLEMENT OUR CURRENT BUSINESS STRATEGY. AS A RESULT,
YOU MAY NOT BE ABLE TO EVALUATE OUR BUSINESS PROSPECTS BASED ON OUR HISTORICAL
RESULTS.

    In late 1998, we began to implement our current business strategy of
targeting small and medium sized enterprises in high growth secondary markets
not only within the mid-Atlantic United States, but also outside of such region.
Prior to 1998, we conducted business solely in the mid-Atlantic area,
particularly in Eastern Pennsylvania. Consequently, the evaluation of our future
business prospects is difficult because our historical results for periods
during which we were implementing our current business strategy are limited.

WE HAVE A HISTORY OF LOSSES AND EXPECT FUTURE LOSSES.

    We have incurred net losses since our inception. For the years ended
December 31, 1996, 1997, 1998 and 1999, we had losses of $115,000, $322,000,
$1.3 million and $5.6 million, respectively. On a pro forma basis, assuming that
the acquisition of Internet Unlimited, Inc. was consummated on January 1, 1998,
we would have incurred net losses of approximately $2.6 million, or 42% of
revenues, for the year ended December 31, 1998 and approximately $6.5 million,
or 71% of revenues, for year ended December 31, 1999. Under our current business
strategy, we expect to continue to operate at a loss for the foreseeable future.

    In order to achieve profitability, we must develop and market products and
services that gain broad commercial acceptance by small and medium sized
enterprises and residential customers in our target regions. We cannot give any
assurances that our products and services will ever achieve broad commercial
acceptance among our customers. Although our revenues have increased each year
since we began operations, we cannot give any assurances that this growth in
annual revenues will continue or lead to our profitability in the future.
Therefore, we cannot predict whether we will obtain or sustain positive
operating cash flow or generate net income in the future.

OUR OPERATING RESULTS FLUCTUATE DUE TO A VARIETY OF FACTORS AND ARE NOT A
MEANINGFUL INDICATOR OF FUTURE PERFORMANCE.

    Our operating results have fluctuated in the past and may fluctuate
significantly in the future, depending upon a variety of factors, including:

    - the timing of costs relating to the construction of our customer network
      facilities;

    - the timing of the introduction of new products and services;

    - changes in pricing policies and product offerings by us or our
      competitors; and

    - fluctuations in demand for Internet access and enhanced products and
      services.

    Therefore, we believe that period-to-period comparisons of our operating
results are not necessarily meaningful and cannot be relied upon as indicators
of future performance. If our operating results in any future period fall below
the expectations of common stock analysts and investors, the market price of our
common stock would likely decline.

                                       15

OUR EXPANSION EFFORTS MAY NOT BE SUCCESSFUL IN OUR NEW TARGET REGIONS BECAUSE
OUR BUSINESS GROWTH STRATEGY IS LARGELY UNTESTED.

    Our growth strategy includes building customer network facilities in high
growth secondary markets where we do not currently operate. In each market, we
will target primarily small and medium sized enterprise customers. Since our
growth strategy is largely untested, we cannot give any assurances that we will
be able to successfully implement it in our target regions.

    Our success will depend upon:

    - our ability to identify attractive target regions outside of the
      mid-Atlantic area;

    - our ability to rapidly deploy additional customer network facilities; and

    - our ability to replicate our sales and marketing efforts.

    Our ability to successfully implement our business strategy, and the
expected benefits to be obtained from our strategy, may be adversely affected by
a number of factors, such as unforeseen costs and expenses, technological
change, economic downturns, competitive factors or other events beyond our
control.

FOR THE YEAR ENDED DECEMBER 31, 1999, OUR LARGEST CUSTOMER ACCOUNTED FOR 21% OF
OUR TOTAL REVENUES. THE LOSS OF THIS CUSTOMER COULD HARM OUR RESULTS OF
OPERATIONS.

    Although our primary business strategy is to target small and medium sized
enterprises, we currently derive, and expect in the future to derive, a
significant portion of our revenues from a small number of our business
customers that are not small and medium sized enterprises. For example, Lucent
Technologies, Inc. accounted for 7% of total revenues for the year ended
December 31, 1999 and 11% of total revenues for the fiscal year ended
December 31, 1998 and Microsoft's WebTV Networks, Inc. accounted for 21% of
total revenues for the year ended December 31, 1999 and 9% of total revenues for
the fiscal year ended December 31, 1998. If we are unable to implement our
strategy of targeting small and medium sized enterprises, we will continue to be
substantially dependent upon revenues from our larger customers. We expect
revenues from these customers to vary from year to year. Our agreement with
Microsoft's WebTV Networks may be terminated upon 120 days notice. The loss of
any of our significant customers or a significant decrease in revenues from
these customers could harm our results of operations.

IN THE FUTURE, WE MAY BE UNABLE TO EXPAND OUR SALES, TECHNICAL SUPPORT AND
CUSTOMER SUPPORT INFRASTRUCTURE, WHICH MAY HINDER OUR ABILITY TO GROW AND MEET
CUSTOMER DEMANDS.

    We rely upon our centralized sales force and regional marketing managers to
sell our products and services in our new regions. We serve our existing
customers through our sales, technical support and customer support staff. If,
in the future, we are unable to expand our sales force and our technical support
and customer support staff, our business would be harmed because this would
limit our ability to obtain new customers, sell products and services and
provide existing customers with a high level of technical support.

IF WE ARE UNABLE TO RAPIDLY EXPAND INTO OUR TARGET REGIONS, WE MAY NEED TO
MODIFY OUR GROWTH AND OPERATING PLANS.

    Our business strategy depends on our ability to rapidly expand into our new
regions, which requires significant capital resources. As a result, we may need
significant additional funds to execute our growth strategy. If our existing
cash is not sufficient to meet our cash requirements, our need to fund our
ongoing operations could limit our ability to execute our business strategy.
Therefore, we will need to seek additional capital from public or private equity
and debt sources to fund our growth and

                                       16

operating strategies. We cannot be certain that we will be able to raise
additional capital in the future on terms acceptable to us or at all. If
alternative sources of financing are insufficient or unavailable, we may be
required to modify our growth and operating plans in accordance with the extent
of available financing.

    In the past, we have been able to provide limited services to customers
90 days after the date construction begins for a new customer network facility.
There are many factors, however, which may affect our ability to expand rapidly
into target regions, including availability of equipment and telecommunications
services. Therefore, there can be no assurances that we will be able to expand
into our target regions in our anticipated time frame. If we are unable to
rapidly expand into our target regions, our business and results of operations
will be harmed.

WE FACE SIGNIFICANT AND INCREASING COMPETITION IN OUR INDUSTRY WHICH COULD CAUSE
US TO LOWER PRICES RESULTING IN REDUCED REVENUES.

    The growth of the Internet access and related services market and the
absence of substantial barriers to entry have attracted many start-ups as well
as existing businesses from the telecommunications, cable, and technology
industries. As a result, the market for Internet access and related services is
very competitive. We anticipate that competition will continue to intensify as
the use of the Internet grows. Current and prospective competitors include:

    - national Internet service providers and regional and local Internet
      service providers, including providers of free dial-up Internet access;

    - national and regional long distance and local telecommunications carriers;

    - cable operators and their affiliates;

    - providers of web hosting, colocation and other Internet-based business
      services;

    - computer hardware and other technology companies that bundle Internet
      connections with their products; and

    - terrestrial wireless and satellite Internet service providers.

    We believe that the number of competitors we face is significant and is
constantly changing. As a result, it is extremely difficult for us to accurately
identify and quantify our competitors. In addition, because of the constantly
evolving competitive environment, it is extremely difficult for us to determine
our relative competitive position at any given time.

    As a result of an increase in the number of competitors, and vertical and
horizontal integration in the industry, we currently face and expect to continue
to face significant pricing pressure and other competition in the future.
Advances in technology and changes in the marketplace and the regulatory
environment will continue, and we cannot predict the effect that ongoing or
future developments may have on us or the pricing of our products and services.

    We believe that the following are the primary competitive factors in our
market:

    - pricing;

    - quality and breadth of products and services;

    - ease of use;

    - personal customer support and service; and

    - brand awareness.

                                       17

    Many of our competitors have significantly greater market presence,
brand-name recognition, and financial resources than we do. In addition, all of
the major long distance telephone companies, also known as interexchange
carriers, offer Internet access services. The recent reforms in the federal
regulation of the telecommunications industry have created greater opportunities
for local exchange carriers, including incumbent local exchange carriers and
competitive local exchange carriers, to enter the Internet access market. In
order to address the Internet access requirements of the current business
customers of long distance and local carriers, many carriers are integrating
horizontally through acquisitions of or joint ventures with Internet service
providers, or by wholesale purchase of Internet access from Internet service
providers. In addition, many of the major cable companies and other alternative
service providers, such as those companies utilizing wireless and
satellite-based service technologies, have announced their plans to offer
Internet access and related services. While few of these larger companies have
focused on our key customer base of small and medium sized enterprises in our
target markets, it is possible that they will do so in the future. Accordingly,
we may experience increased competition from traditional and emerging
telecommunications providers. Many of these companies, in addition to their
substantially greater network coverage, market presence, and financial,
technical and personnel resources, also already provide telecommunications and
other services to many of our target customers. Furthermore, they may have the
ability to bundle Internet access with basic local and long distance
telecommunications services, which we do not currently offer. This bundling of
services may harm our ability to compete effectively with them and may result in
pricing pressure on us that would reduce our earnings.

OUR GROWTH DEPENDS ON THE CONTINUED ACCEPTANCE BY SMALL AND MEDIUM SIZED
ENTERPRISES OF THE INTERNET FOR COMMERCE AND COMMUNICATION.

    If the use of the Internet by small and medium sized enterprises for
commerce and communication does not continue to grow, our business and results
of operations will be harmed. Our products and services are designed primarily
for the rapidly growing number of business users of the Internet. Commercial use
of the Internet by small and medium sized enterprises is still in its early
stages. Despite growing interest in the commercial uses of the Internet, many
businesses have not purchased Internet access and related services for several
reasons, including:

    - lack of inexpensive, high-speed connection options;

    - a limited number of reliable local access points for business users;

    - lack of affordable electronic commerce solutions;

    - limited internal resources and technical expertise;

    - inconsistent quality of service; and

    - difficulty in integrating hardware and software related to Internet based
      business applications.

    In addition, we believe that many Internet users lack confidence in the
security of transmitting their data over the Internet, which has hindered
commercial use of the Internet. Technologies that adequately address these
security concerns may not be developed.

    The adoption of the Internet for commerce and communication applications,
particularly by those enterprises that have historically relied upon alternative
means, generally requires the understanding and acceptance of a new way of
conducting business and exchanging information. In particular, enterprises that
have already invested substantial resources in other means of conducting
commerce and exchanging information may be reluctant or slow to adopt a new
strategy that may make their existing personnel and infrastructure obsolete.

                                       18

OUR SUCCESS DEPENDS ON THE CONTINUED DEVELOPMENT OF INTERNET INFRASTRUCTURE.

    The recent growth in the use of the Internet has caused periods of
performance degradation, requiring the upgrade by providers and other
organizations with links to the Internet of routers and switches,
telecommunications links and other components forming the infrastructure of the
Internet. We believe that capacity constraints caused by rapid growth in the use
of the Internet may impede further development of the Internet to the extent
that users experience increased delays in transmission or reception of data or
transmission errors that may corrupt data. Any degradation in the performance of
the Internet as a whole could impair the quality of our products and services.
As a consequence, our future success will be dependent upon the reliability and
continued expansion of the Internet.

WE RELY ON A LIMITED NUMBER OF VENDORS AND SERVICE PROVIDERS, SOME OF WHICH ARE
OUR COMPETITORS. THIS MAY ADVERSELY AFFECT THE FUTURE TERMS OF OUR
RELATIONSHIPS.

    We rely on other companies to supply key components of our network
infrastructure, which are available only from limited sources. For example, we
currently rely on routers, switches and remote access devices from Lucent
Technologies, Inc., Cisco Systems, Inc. and Nortel Networks Corporation. We
could be adversely affected if any of these products were no longer available on
commercially reasonable terms, or at all. From time to time, we experience
delays in the delivery and installation of these products and services, which
can lead to the loss of existing or potential customers. We do not know that we
will be able to obtain such products in the future cost-effectively and in a
timely manner. Moreover, we depend upon Sprint Communications Company, L.P., MCI
WorldCom, Inc. and UUNET Technologies, Inc. as our primary backbone providers.
These companies also sell products and services that compete with ours. Our
agreements with our primary backbone providers are fixed price contracts with
terms ranging from one to three years. Our backbone providers operate national
or international networks that provide data and Internet connectivity and enable
our customers to transmit and receive data over the Internet. Our relationship
with these backbone providers could be adversely affected as a result of our
direct competition with them. Failure to renew these relationships when they
expire or enter into new relationships for such services on commercially
reasonable terms or at all could harm our business, financial condition and
results of operations.

WE DEPEND ON OUR EXECUTIVE OFFICERS TO EXECUTE OUR BUSINESS STRATEGY AND COULD
BE HARMED BY THE LOSS OF THEIR SERVICES.

    Our success depends in part upon the continued service and performance of:

    - David K. Van Allen, Chief Executive Officer;

    - Sonny C. Hunt, President;

    - Stanley F. Bielicki, Chief Financial Officer;

    - Phillip L. Weller, Chief Technology Officer;

    - Rafe Scheinblum, Executive Vice President--Operations;

    - Mark A. Horinko, Vice President--Engineering; and

    - Thomas J. Roberts, Vice President--Sales.

    We currently do not have employment agreements with any of our named
executive officers. The loss of the services of one or more of our executive
officers could impair our ability to expand our operations and provide a high
level of service to our customers.

                                       19

WE NEED TO RECRUIT AND RETAIN QUALIFIED PERSONNEL OR OUR BUSINESS COULD BE
HARMED.

    Competition for highly-qualified employees in the Internet service industry
is intense because there is a limited number of people with an adequate
knowledge of and significant experience in our industry. Our success depends to
a significant degree upon our ability to attract, train and retain highly
skilled management, technical, marketing and sales personnel and upon the
continued contributions of such people. Since it is difficult and time consuming
to identify and hire highly qualified employees, we cannot assure you of our
ability to do so. Our failure to attract additional highly qualified personnel
could impair our ability to grow our operations and services to our customers.

WE COULD EXPERIENCE SYSTEM FAILURES AND CAPACITY CONSTRAINTS, WHICH COULD RESULT
IN THE LOSS OF OUR CUSTOMERS OR LIABILITY TO OUR CUSTOMERS.

    The continued operation of our network infrastructure depends upon our
ability to protect against:

    - downtime due to malfunction or failure of hardware or software;

    - overload conditions;

    - power loss or telecommunications failures;

    - human error;

    - natural disasters; and

    - sabotage or other intentional acts of vandalism.

    Any of these occurrences could result in interruptions in the services we
provide to our customers and require us to spend substantial amounts of money
repairing and replacing equipment. In addition, we have finite capacity to
provide service to our customers under our current infrastructure. Because
utilization of our network is constantly changing depending upon customer use at
any given time, we maintain a level of capacity that we believe to be adequate
to support our current customer base. If we obtain additional customers in the
future, we will need to increase our capacity to maintain the quality of service
that we currently provide our customers. If customer usage exceeds our capacity
and we are unable to increase our capacity in a timely manner, our customers may
experience interruptions in or decreases in quality of the services we provide.
As a result, we may lose current customers or incur significant liability to our
customers for any damages they suffer due to any system downtime as well as the
possible loss of customers.

OUR NETWORK MAY EXPERIENCE SECURITY BREACHES WHICH COULD DISRUPT OUR SERVICES.

    Our network infrastructure may be vulnerable to computer viruses, break-ins
and similar disruptive problems caused by our customers or other Internet users.
Computer viruses, break-ins or other problems caused by third parties could lead
to interruptions, delays or cessation in service to our customers. There
currently is no existing technology that provides absolute security, and the
cost of minimizing these security breaches could be prohibitively expensive. We
may face liability to customers for such security breaches. Furthermore, such
incidents could deter potential customers and adversely affect existing customer
relationships.

WE FACE POTENTIAL LIABILITY FOR INFORMATION DISSEMINATED THROUGH OUR NETWORK.

    It is possible that claims could be made against Internet service providers
in connection with the nature and content of the materials disseminated through
their networks. The law relating to the liability of Internet service providers
due to information carried or disseminated through their networks is not
completely settled. While the U.S. Supreme Court has held that content
transmitted over the Internet is entitled to the highest level of protection
under the U.S. Constitution, there are federal and

                                       20

state laws regarding the distribution of obscene, indecent, or otherwise illegal
material, as well as material that violates intellectual property rights which
may subject us to liability. Several private lawsuits have been brought in the
past and are currently pending against other entities which seek to impose
liability upon Internet service providers as a result of the nature and content
of materials disseminated over the Internet. If any of these actions succeed, we
might be required to respond by investing substantial resources or discontinuing
some of our service or product offerings, which could harm our business.

NEW LAWS AND REGULATIONS GOVERNING OUR INDUSTRY COULD HARM OUR BUSINESS.

    We are subject to a variety of risks that could materially affect our
business due to the rapidly changing legal and regulatory landscape governing
Internet access providers. For example, the Federal Communications Commission
currently exempts Internet access providers from having to pay per-minute access
charges that long-distance telecommunications providers pay local telephone
companies for the use of the local telephone network. In addition, Internet
access providers are currently exempt from having to pay a percentage of their
gross revenues as a contribution to the federal universal service fund. Should
the Federal Communications Commission eliminate these exemptions and impose such
charges on Internet access providers, this would increase our costs of providing
dial-up Internet access service and could have a material adverse effect on our
business, financial condition and results of operations.

    We face risks due to possible changes in the way our suppliers are regulated
which could have an adverse effect on our business. For example, most states
require local exchange carriers to pay reciprocal compensation to competing
local exchange carriers for the transport and termination of Internet traffic.
However, in February 1999, the Federal Communications Commission concluded that
at least a substantial portion of dial-up Internet traffic is jurisdictionally
interstate which could ultimately eliminate the reciprocal compensation payment
requirement for Internet traffic. Should this occur our telephone carriers may
no longer be entitled to receive payment from the originating carrier to
terminate traffic delivered to us. The Federal Communications Commission has
launched an inquiry to determine a mechanism for covering the costs of
terminating calls to Internet service providers, but in the interim state
commissions will determine whether carriers will receive compensation for such
calls. If the new compensation mechanism that may be adopted by the Federal
Communications Commission increases the costs to our telephone carriers for
terminating traffic to us, or if states eliminate reciprocal compensation
payments, our telephone carriers may increase the price of service to us in
order to recover such costs. This could have a material adverse effect on our
business, financial condition and results of operations.

    We face risks due to possible changes in the way our competitors are
regulated which could have an adverse effect on our business. For example, the
Federal Communications Commission is considering measures that could stimulate
the development of high-speed telecommunications facilities and make it easier
for operators of these facilities to obtain access to customers. Such favorable
regulatory measures could enhance the viability of our competitors in the
Internet access marketplace. In addition, changes in the regulatory environment
may provide competing Internet service providers the right of access to the
cable systems of local franchised cable operators. The adoption of open access
to cable systems by Internet service providers could harm our business.

    IMPACT OF THE YEAR 2000 The commonly referred to Year 2000 or Y2K issue
results from the fact that many computer programs and systems were developed
without considering the possible impact of a change in the century designation
that occurred on January 1, 2000. As a result, these programs and systems use
only two digits instead of four to identify the year in the date field. Many
people were concerned that essential systems and programs might not properly
recognize this date and therefore could generate wrong data, calculate erroneous
results, or fail if the issue remained uncorrected. As a result of these
concerns, we undertook a pervasive inventory, internal assessment,

                                       21

and service-level testing effort across all of our operations. Based on these
initiatives we discovered certain non-material Y2K compliance issues and took
appropriate corrective actions in advance of January 1, 2000. On January 1, 2000
and since that time, we have not experienced any significant Year 2000 problems
in connection with any of our systems or operations. Based on that experience,
we do not expect that we will encounter any significant latent Y2K-related
problems in the future nor incur any significant additional costs. As of
December 31, 1999, we had spent approximately $360,000 in the aggregate in
connection with our Y2K assessment and remediation efforts. These costs included
hardware and software remediation costs incurred in connection with the
compliance program. These costs do not include internal costs for employee time
spent on the project, and various system upgrades that we implemented and that
otherwise would be part of our overall capital expenditure.

ITEM 2. PROPERTIES.

    Our corporate offices are located in Bethlehem, Pennsylvania where we lease
approximately 72,881 square feet of space for our Network Operations Center. Our
lease agreements for this space, which commenced on June 1, 1999 and
September 1, 1999, respectively, have six-year terms. We also entered into a
lease on January 6, 2000 for 34,580 square feet of space for our principal
executive offices with a lease term of six years. This lease agreement includes
a purchase option which expires on January 5, 2001. We also lease space for our
Customer Network Facilities, ranging from 600 to 2,000 square feet, in
Pennsylvania, New Jersey, New York, Washington D.C., and Maryland. We will
require additional space for our customer network facilities as we expand. We
believe that we will continue to be able to obtain suitable space on
commercially reasonable terms.

ITEM 3. LEGAL PROCEEDINGS.

    We are not involved currently in any legal proceedings that either
individually or taken as a whole, will have a material adverse effect on our
business, financial condition and results of operations.

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

    No matter was submitted to a vote of security holders in the fourth quarter
of the fiscal year covered by this report.

                                    PART II.

ITEM 5. MARKET FOR THE REGISTRANT'S SECURITIES AND RELATED SHAREHOLDER MATTERS.

    Our common stock has traded on the Nasdaq National Market (Nasdaq Symbol:
FSST) since the completion of our initial public offering ("IPO") on
February 7, 2000. Prior to that date, there was no public market for our common
stock.

    On March 24, 2000, the closing price of our common stock as reported on the
Nasdaq National Market was $14.13 per share. As of March 24, 2000, there were
approximately 169 shareholders of record of our common stock.

    We have never declared or paid any cash dividends on our common stock and do
not expect to pay dividends in the foreseeable future. Our current policy is to
retain all of our earnings to finance future growth and working capital needs.

    Our initial public offering, or IPO, was effected through a Registration
Statement on Form S-1 (File No. 333-85465) that was declared effective by the
SEC on February 7, 2000 and pursuant to which we sold an aggregate of 4,000,000
shares of our common stock at $12.00 per share. On March 7, 2000, the managing
underwriters of our IPO, ING Barings LLC, SoundView Technology Group, Inc., FAC/
Equities, a division of First Albany Corporation and DLJDIRECT, Inc., exercised
the over-allotment option selling an additional 600,000 shares of our common
stock. Total aggregate proceeds were $55.2 million.

    In the preceding three years, we have issued the following securities that
were not registered under the Securities Act:

    Since our inception, we have issued to employees and H&Q You Tools
Investment Holding, L.P. an aggregate of 7,000,000 shares of common stock and to
employees and directors options to purchase 585,000 shares issued pursuant to
our Equity Compensation Plan. All of such sales were made under the exemption
from registration provided under Section 4(2) of the Securities Act.

    On May 28, 1998, we sold 1,000,000 shares of common stock for $0.20 per
share and a warrant to purchase 1,000,000 shares of our common stock at a per
share exercise price of $1.50. This warrant is exercisable at any time on or
before May 30, 2005 to H&Q You Tools Investment Holding L.P. This sale was made
under the exemption from registration provided under Section 4(2) of the
Securities Act.

    Pursuant to our Equity Compensation Plan, we have granted, as of
December 31, 1999, options to purchase a total of 585,000 shares of common
stock, of which 450,000 are exercisable at a price of $1.50 per share; 115,000
are exercisable at a price of $2.50 per share and 20,000 are exercisable at a
price of $7.13 per share. No options have been exercised. In granting the
options and selling the underlying securities upon exercise of the options, we
relied upon exemptions from registration set forth in Rule 701 and Section 4(2)
of the Securities Act.

    On July 30, 1999, we issued 546,984 shares of our common stock to the
shareholders of Internet Unlimited, Inc. in connection with our acquisition of
Internet Unlimited, Inc. These sales were made under the exemption from
registration provided under Section 4(2) of the Securities Act.

    In August 1999, we sold 666,198 shares of Series A convertible preferred
stock to H&Q You Tools Investment Holding L.P., Naveen Jain, Everest Venture
Partners I, L.P., Entrepreneurial Investment Corporation, J.F. Shea Co. Inc., as
nominee, Lucent Technologies, Inc, InterNetworking Systems, at a price of $7.13
per share. All of these sales were made under the exemption from registration
provided under Section 4(2) of the Securities Act. All of these shares of
preferred stock were converted into 666,198 shares of our common stock
immediately prior to the consummation of our IPO.

                                       23

OVERVIEW

    We began providing Internet access services to our customers in 1994. In
1998, we began to implement our current strategy of providing Internet access
and enhanced products and services to small and medium sized enterprises in
selected high growth markets. In order to fund this strategy, we decided to seek
financing through the issuance of additional equity and debt.

    - In May 1998, we raised approximately $3.3 million in a private debt and
      equity financing, of which approximately $1.5 million was used to retire
      debt and repurchase outstanding shares of our common stock. We used the
      remainder of the proceeds to advance our business plan.

    - In May 1999, we raised $1.0 million from H&Q You Tools Investment Holding,
      L.P. through the issuance of a convertible note. The principal and accrued
      interest on this note were converted in August 1999 into 142,431 shares of
      series A convertible preferred stock at $7.13 per share. In August 1999,
      we sold 666,198 shares of series A convertible preferred stock at $7.13
      per share for net proceeds of approximately $4.5 million to a group of
      investors including Lucent Technologies, Inc. All of the outstanding
      preferred stock converted automatically into an equivalent number of
      common shares upon the consummation of the Company's initial public
      offering (see below).

    On July 30, 1999 we acquired Internet Unlimited, Inc., a web hosting and
colocation company located in Bethlehem, Pennsylvania. As a result of this
acquisition, we increased the number of customers using our web hosting services
and supplemented our management and technical expertise.

    On February 7, 2000, the company completed its initial public offering (the
"Offering") of 4,000,000 shares of Common stock at a price of $12.00 per share.
On March 7, 2000 the Company sold 600,000 shares of common stock at a price of
$12.00 per share pursuant to the exercise of the underwriters' overallotment
option. The Company received aggregate net cash proceeds of $51,336,000 from the
initial public offering and exercise of the over allotment option.

OUR HISTORY OF OPERATING LOSSES

    We have incurred operating losses in each year since our inception. Our
operating losses were 8% of revenues for the year ended December 31, 1997, 20%
for the year ended December 31, 1998 and 62% of revenues for the year ended
December 31, 1999. On a pro forma basis, assuming the acquisition of Internet
Unlimited was consummated on January 1, 1998, our losses would have increased
from 20% of revenues on an actual basis to 41% on a pro forma basis for the year
ended December 31, 1998, and would have increased from 62% on an actual basis to
67% on a pro forma basis for the year ended December 31, 1999. We anticipate
that we will continue to operate at a loss for the foreseeable future.

                                       25

RESULTS OF OPERATIONS

    We broadly classify our revenues by customer type, enterprise and
non-enterprise. Enterprise customers are business customers, governmental
entities, and non-profit organizations. Our non-enterprise customers are
residential customers and Microsoft's WebTV Networks' customers. We historically
have derived at least 60% of our revenues from our enterprise customers. Our
customers purchase Internet access, web hosting services and other enhanced
products and services either individually or as part of a bundled solution.

    Typically, our customers sign annual service contracts that set forth their
charges for recurring services, and may include one time set up fees. We offer
our customers monthly, quarterly, semi-annual and annual service periods and
provide discounts to our customers for prepayment and for purchase of bundled
services. In most cases, our customers are invoiced 30 days prior to the start
of their service period. In only a limited number of instances are our customers
invoiced after services have been provided. Revenues are recognized as services
are rendered. Amounts billed relating to future periods are recorded as deferred
revenues and recognized as services are rendered.

    Dedicated Internet access, virtual private networking and dial-up Internet
access together represent more than 60% of our revenues in each period
presented. Our dedicated Internet access revenue has grown in each period and
represented approximately $1.8 million in 1997, $2.9 million in 1998 and
$3.3 million in 1999. Revenues from our virtual private networking service,
which we began offering in 1997, were $679,000 and $2.1 million for the years
ended December 31, 1998 and 1999, respectively. This increase in virtual private
networking revenues is primarily attributable to the increase in Microsoft's
WebTV Networks' customers utilizing this service and our expansion into new
regions. Dial-up access revenues increased from approximately $147,000 in 1996
to approximately $733,000 in 1998 and approximately $1.4 million in the year
ended December 31, 1999. This growth is primarily attributable to expansion of
our customer base and increased sales and marketing efforts.

    Our primary focus is on generating recurring revenues from small and medium
sized business customers. Currently, revenues from enterprise customers
represent more than 60% of total revenues. During the years ended December 31,
1997 and 1998, revenues from the sale of our enhanced products and services
represented between 11% and 17% of our total revenues. On a pro forma basis
assuming our acquisition of Internet Unlimited, Inc. occurred on January 1,
1998, enhanced products and services revenues would have been 19% of revenues in
the year ended December 31, 1998 and 18% of revenues for the year ended
December 31, 1999. We anticipate that enhanced products and services revenues
will increase as a percentage of our total revenues in the future.

    As our revenues have grown, we have increased the number of our employees,
expanded our facilities and infrastructure, and increased our sales and
marketing efforts. We had 19 employees at December 31, 1996, 33 employees at
December 31, 1997, 41 employees at December 31, 1998, 91 employees at
December 31, 1999. As of December 31, 1996, we operated our network operations
center and one customer network facility. As of December 31, 1999, we had
expanded the capabilities of the network operations center and had seven
customer network facilities in operation with five additional customer network
facilities in construction. Our advertising expenditures increased from $243,000
in 1997 to $625,000 in 1998 to $1.0 million in 1999. We expect to continue to
increase the number of our employees, to expand our facilities and
infrastructure, and to increase our sales and marketing efforts. As a
consequence, we expect operating expenses to continue to increase for the
foreseeable future.

    Cost of services revenues consists primarily of Internet access and
telecommunications charges. These charges are the costs of directly connecting
to Internet backbone providers. Cost of services revenues also includes the
payroll and related expenses for engineering, and rental expense on leased
network and customer network facility equipment. Costs of hardware and software
includes the costs of third party hardware and software sold to our customers.

                                       26

    Selling, general and administrative expense consists primarily of payroll
and related expenses for personnel engaged in marketing, selling, customer
service, accounting, management, and administrative functions. Selling, general
and administrative expense includes office space rent, advertising, promotion,
insurance, professional fees, as well as other general corporate expenses.

    The following table sets forth statement of operations data as a percentage
of revenues for the periods indicated:

YEAR ENDED DECEMBER 31, 1999 COMPARED TO THE YEAR ENDED DECEMBER 31, 1998.

    REVENUES.  Total revenues increased by $2.9 million, or 52%, to
$8.4 million for the year ended December 31, 1999, compared to $5.5 million for
the year ended December 31, 1998. On a pro forma basis, assuming our acquisition
of Internet Unlimited, Inc. occurred prior to January 1, 1999, total revenues
would have been $9.1 million for the year ended December 31, 1999.

    Services revenues increased by $3.3 million, or 68%, to $8.2 million for the
year ended December 31, 1999, compared to $4.9 million for the year ended
December 31, 1998. This increase in services revenues is primarily attributable
to an increase in the number of customers using our dedicated Internet access
services and a 211% increase in virtual private network revenues from $679,000
for the period ended December 31, 1998 to $2.1 million for the period ended
December 31, 1999. This increase in virtual private networking revenues is
primarily attributable to the increase in revenues from one customer,
Microsoft's WebTV Networks. Our enhanced products and service revenues increased
by 152% for the period ended December 31, 1999 over the same period in 1998 in
part due to our acquisition of Internet Unlimited, Inc. Our dial-up customer
base continued to grow over the comparable period, resulting in an increase in
dial-up revenues of 95% for the period ended December 31, 1999 over the same
twelve month period in 1998.

    Hardware and software revenues which represents our resale of third party
hardware and software to our customers decreased by $441,000 or 68% to $212,000
for the year ended December 31, 1999, compared to $653,000 for the year ended
December 31, 1998. In the year ended December 31, 1998, we sold a significant
amount of third party hardware and software as part of an installation for one
of our major customers. We expect hardware sales to decline as a percentage of
revenue because of our focus on small and medium sized enterprises. These
customers historically have required less hardware because of the scale of their
Internet needs and their inclination to use their existing equipment when
available.

                                       27

    During these periods, we derived a significant portion of our revenues from
Microsoft's WebTV Networks and the State of Delaware. Microsoft's WebTV Networks
represented 21% of total revenues for the year ended December 31, 1999. The
State of Delaware represented 11% of total revenues for the year ended
December 31, 1998.

    COST OF REVENUES.  Cost of revenues increased by $2.4 million, or 75%, to
$5.7 million for the year ended December 31, 1999, compared to $3.2 million for
the year ended December 31, 1998. As a percentage of revenues, cost of revenue
increased to 68% for the year ended December 31, 1999 from 59% for the year
ended December 31, 1998. On a pro forma basis, assuming our acquisition of
Internet Unlimited, Inc. occurred prior to January 1, 1999, cost of revenues
would have been $5.8 million for the year ended December 31, 1999.

    Cost of services increased by $2.9 million, or 113%, to $5.5 million for the
year ended December 31, 1999, compared to $2.6 million for the year ended
December 31, 1998. As a percentage of services revenues, cost of services were
53% in the year ended December 31, 1998 compared to 67% in the year ended
December 31, 1999. These increases were primarily attributable to the increase
in Internet access and telecommunications charges, increased rental expense on
leased equipment, and an increase in payroll and related expenses for engineers
associated with our increased revenues, in advance of generating revenues in new
regions.

    Cost of hardware and software decreased by $485,000 or 72% to $184,000 for
the year ended December 31, 1999, compared to $669,000 for the year ended
December 31, 1998 as a result of the decrease in hardware and software revenues.

    SELLING, GENERAL AND ADMINISTRATIVE.  Selling, general and administrative
expenses increased by $3.3 million, or 107%, to $6.4 million for the year ended
December 31, 1999 compared to $3.1 million for the year ended December 31, 1998.
As a percentage of revenues, selling, general and administrative expenses
increased to 76% for the year ended December 31, 1999 from 55% for the year
ended December 31, 1998. This increase is primarily attributable to the increase
in selling, general and administrative personnel from 31 at December 31, 1998 to
73 at December 31, 1999, and a 67% increase in advertising expense from $625,000
in the year ended December 31, 1998 to $1.0 million in the year ended
December 31, 1999. As a result of the increase in personnel, all related general
and administrative expenses increased. Five hundred thousand dollars of the
$3.3 million increase was for financial advisory services provided by
Hambrecht & Quist LLC. On a pro forma basis, assuming our acquisition of
Internet Unlimited, Inc. occurred prior to January 1, 1999, selling, general and
administrative expenses would have been $6.9 million for the year ended
December 31, 1999.

    DEPRECIATION AND AMORTIZATION.  Depreciation and amortization increased by
$1.3 million or 362%, to $1.6 million for the year ended December 31, 1999,
compared to $347,000 for the year ended December 31, 1998. This increase was
primarily attributable to the purchase of equipment necessary to support the
expansion of our network and to the amortization of the intangible assets
associated with our acquisition of Internet Unlimited, Inc. On a pro forma
basis, assuming our acquisition of Internet Unlimited, Inc. occurred prior to
January 1, 1999, depreciation and amortization, including the amortization of
intangible assets associated with the Internet Unlimited acquisition would have
been $2.5 million for the year ended December 31, 1999.

YEAR ENDED DECEMBER 31, 1998 COMPARED TO THE YEAR ENDED DECEMBER 31, 1997.

    REVENUES.  Total revenues increased by $1.8 million, or 51%, to
$5.5 million for the year ended December 31, 1998, from $3.7 million for the
year ended December 31, 1997. On a pro forma basis, assuming our acquisition of
Internet Unlimited occurred prior to January 1, 1998, total revenues would have
been $6.1 million for the year ended December 31, 1998.

                                       28

    Services revenues increased by $2.1 million, or 71%, to $4.9 million for the
year ended December 31, 1998, from $2.8 million for the year ended December 31,
1997. This increase in services revenues resulted from an overall increase in
the number of customers using our dedicated Internet access services and from an
increase in virtual private networking revenues for the year ended December 31,
1998, compared, to the year ended December 31, 1997. Our dedicated Internet
access revenues increased by $1.2 million, or 67%, in 1998 compared to 1997. Our
dial-up customer base continued to increase in 1998 compared to 1997, resulting
in dial-up revenues increasing $207,000, or 40%, in 1998 compared to 1997.

    Hardware and software revenues decreased by $171,000, or 21%, to $653,000
for the year ended December 31, 1998, from $824,000 for the year ended
December 31, 1997, primarily because we sold a significant amount of third party
hardware and software as part of an installation for one of our major customers
in 1997.

    During the year ended December 31, 1998, revenues from Lucent
Technologies, Inc. represented in excess of 11% of total revenues. During the
year ended December 31, 1997, revenues from Lucent Technologies, Inc.
represented 24% and revenues from Vanguard Cellular Systems, Inc. represented
13% of total revenues.

    COST OF REVENUES.  Cost of revenues increased by $908,000, or 39%, to
$3.2 million for the year ended December 31, 1998 from $2.3 million for the year
ended December 31, 1997. On a pro forma basis, assuming our acquisition of
Internet Unlimited occurred on January 1, 1998, cost of revenues would have been
$3.3 million for the year ended December 31, 1998.

    Cost of services increased by $801,000, or 45%, to $2.6 million for the year
ended December 31, 1998, from $1.8 million for the year ended December 31, 1997.
This increase was primarily attributable to the increase in Internet access and
telecommunications charges and increased rental expense on leased equipment. As
a percentage of services revenues, cost of services were 53% in the year ended
December 31, 1998 compared to 62% in the year ended December 31, 1997. This
decrease is primarily attributable to a higher utilization rate of our network
and the addition of new customers without proportional incremental
infrastructure and telecommunications costs.

    Cost of hardware and software increased by $107,000 or 19% to $669,000 for
the year ended December 31, 1998, from $562,000 for the year ended December 31,
1997. This increase is primarily attributable to a large sale of hardware to one
customer.

    SELLING, GENERAL AND ADMINISTRATIVE.  Selling, general and administrative
expenses increased by $1.7 million, or 112%, to $3.1 million for the year ended
December 31, 1998 from $1.4 million for the year ended December 31, 1997. As a
percentage of revenues, these expenses were 56% for the year ended December 31,
1998, compared to 39% for the year ended December 31, 1997. This increase in
selling, general and administrative expense in dollars and as a percentage of
revenues is primarily attributable to the increase in selling, general and
administrative personnel from 28 at December 31, 1997 to 35 at December 31,
1998, and a 157% increase in advertising expense from $243,000 in the year ended
December 31, 1997 to $625,000 in the year ended December 31, 1998. On a pro
forma basis, assuming our acquisition of Internet Unlimited occurred on
January 1, 1998, selling, general and administrative expenses would have been
$3.5 million for the year ended December 31, 1998.

    DEPRECIATION AND AMORTIZATION.  Depreciation and amortization increased by
$170,000, or 95%, to $347,000 for the year ended December 31, 1998 from $177,000
for the year ended December 31, 1997. This increase was primarily attributable
to the purchase of equipment necessary to support the expansion of our network.
On a pro forma basis, assuming our acquisition of Internet Unlimited, Inc.
occurred on January 1, 1998, depreciation and amortization, including the
amortization of intangible assets associated with the Internet Unlimited
acquisition, would have been $1.9 million for the year ended December 31, 1998.

LIQUIDITY AND CAPITAL RESOURCES

    Our business plan has required, and is expected to continue to require,
substantial capital to fund operations, capital expenditures, expansion of sales
and marketing capabilities and acquisitions. The following is a table setting
forth our cash flow activities:

    Prior to the offering, we have satisfied our cash requirements primarily
through debt and equity financings. In May 1998, we issued 1,000,000 shares of
our common stock, a convertible promissory note in the amount of approximately
$3.1 million to H&Q You Tools Investment Holding, L.P. and a warrant to purchase
1,000,000 shares of our common stock at an exercise price of $1.50 per share to
H&Q You Tools Investment Holding, L.P. for an aggregate of approximately
$3.3 million in cash. In connection with this financing, we granted H&Q You
Tools Investment Holding, L.P. a security interest in substantially all of our
assets. H&Q You Tools Investment Holding, L.P. has committed to convert this
note into 2,033,334 shares of our common stock and release its security interest
immediately prior to the offering. We used a portion of the proceeds from this
financing to repurchase outstanding shares of our common stock representing 50%
of our then outstanding shares of common stock for $1.0 million.

    In May 1999, we issued a $1.0 million convertible note to H&Q You Tools
Investment Holding, L.P. for $1.0 million in cash. The principal amount of this
note and accrued interest was converted into 142,431 shares of series A
convertible preferred stock at $7.13 per share in August 1999. In July 1999, we
used a portion of the proceeds from this financing to acquire Internet
Unlimited, Inc. a provider of web hosting and colocation services, for $400,000
in cash and 546,984 shares of common stock.

    In August 1999, we sold 666,198 shares of series A convertible preferred
stock to purchasers including Lucent Technologies, Inc. at $7.13 per share. The
net proceeds from these sales of series A convertible preferred stock were
approximately $4.5 million. All of the outstanding preferred stock automatically
converted into common stock immediately prior to the consummation of the initial
public offering.

    In June 1999, we entered into a master lease agreement with Ascend Credit
Corporation for a $20 million equipment lease facility. Under this arrangement,
we lease equipment necessary for the construction of our customer network
facilities. Currently, we have approximately $16.4 million available under this
facility.

    In January 2000, we entered into a purchase agreement under which we issued
a $1.0 million note to H&Q You Tools Investment Holding, L.P. The note bore
interest at a rate equal to 7% per annum and was fully repaid on March 2, 2000
with a portion of the proceeds from the initial public offering.

    As of December 31, 1999, our cash and cash equivalents were $953,840. We
believe that our existing cash and cash equivalents, available financing under
the $20 million equipment lease facility, and the proceeds from the initial
public offering will be sufficient to meet our working capital and capital
expenditure requirements for at least the next 12 months. However, we may be
required to seek additional sources of financing, in order to fund the planned
expansion of the Company. If additional

                                       30

funds are raised through the issuance of equity securities, our existing
shareholders may experience significant dilution. Furthermore, additional
financing may not be available when needed or, if available, such financing may
not be on terms favorable to us or our shareholders. If such sources of
financing are insufficient or unavailable, or if we experience shortfalls in
anticipated revenue or increases in anticipated expenses, we may need to slow
down or stop the expansion of our regional deployment, including our customer
network facilities and reduce our marketing and development efforts. Any of
these events could harm our business, financial condition or results of
operations.

ITEM 7A. QUALITATIVE AND QUANTITATIVE DISCLOSURE ABOUT MARKET RISK.

    Our financial instruments primarily consist of debt. All of our debt
instruments bear interest at fixed rates. Therefore, a change in interest rates
would not affect the interest incurred or cash flows related to our debt. A
change in interest rates would, however, affect the fair value of the debt. The
following sensitivity analysis assumes an instantaneous 100 basis point move in
interest rates from levels at December 31, 1999 with all other factors held
constant. A 100 basis point increase or decrease in market interest rates would
result in a change in the value of our debt of less than $50,000 at
December 31, 1999. Because our debt is neither publicly traded nor redeemable at
our option, it is unlikely that such a change would impact our financial
statements or results of operations.

    All of our transactions are conducted using the United States dollar.
Therefore, we are not exposed to any significant market risk relating to
currency rates.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To FASTNET Corporation:

    We have audited the accompanying consolidated balance sheets of FASTNET
Corporation (a Pennsylvania Corporation) and Subsidiary as of December 31, 1998
and 1999, and the related consolidated statements of operations, shareholders'
equity and cash flows for each of the three years in the period ended
December 31, 1999. These financial statements are the responsibility of the
Company's management. Our responsibility is to express an opinion on these
financial statements based on our audits.

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

    In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of FASTNET
Corporation and Subsidiary as of December 31, 1998 and 1999, and the results of
their operations and their cash flows for each of the three years in the period
ended December 31, 1999, in conformity with accounting principles generally
accepted in the United States.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. THE COMPANY:

    FASTNET Corporation (formerly You Tools Corporation) and its subsidiary
("FASTNET" or the "Company"), a Pennsylvania corporation, has been providing
Internet access and enhanced products and services to its customers since 1994.
The Company is a growing Internet services provider targeting small and medium
sized enterprises in selected high growth secondary markets. The Company
complements its Internet access services by delivering a wide range of enhanced
products and services that are designed to meet the needs of its target customer
base.

    As of December 31, 1999, the Company had a working capital deficit of
$3,238,257 and accumulated losses of $7,531,630. The Company has incurred losses
since inception and expects to continue to incur losses in 2000. The Company
intends to expand its operation into new regions throughout the United States.
To do so, the Company plans to construct and deploy new facilities, increase its
sales and marketing operations and enhance its infrastructure. The Company
completed its initial public offering of 4,000,000 shares of Common stock at a
price of $12.00 per share on February 7, 2000 raising net proceeds of
approximately $43,040,000. In addition, on March 7, 2000, the underwriters
exercised their over-allotment option of 600,000 shares of Common stock at a
price of $12.00 per share. The Company received net proceeds of $6,696,000. (see
Note 10).

    The Company is subject to those risks associated with companies in the early
stages of development. The Company's future results of operations involve a
number of risks and uncertainties. Factors that could affect the Company's
future operating results and cause actual results to vary materially from
expectations include, but are not limited to, dependence on major customers,
risks from competition, new products and technological change, and dependence on
key personnel.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

PRINCIPLES OF CONSOLIDATION

    The accompanying consolidated financial statements include the accounts of
FASTNET and its wholly owned subsidiary. All material intercompany balances and
transactions have been eliminated in consolidation.

USE OF ESTIMATES

    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent 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

    The Company considers all highly liquid investments purchased with an
original maturity of three months or less to be cash equivalents.

PROPERTY AND EQUIPMENT

    Property and equipment are stated at cost. Depreciation and amortization are
provided on the straight-line basis over the estimated useful lives of the
respective assets, which range from 3 to 7 years. Maintenance, repairs and minor
replacements are charged to expense as incurred.

                                      F-6

                       FASTNET CORPORATION AND SUBSIDIARY

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)

    Effective July 1, 1999, the Company changed its method of depreciation for
property and equipment from mid-year convention to mid-month convention. This
change was applied on a prospective basis (as a change in accounting estimate)
to assets acquired after that date. The Company changed its method of
depreciation based upon management's belief that the mid-month convention
provides a better matching of costs and revenues and the fact that the mid-month
convention is the predominant method in practice. The effect of the change on
the net loss for the year ended December 31, 1999 was to decrease the net loss
by approximately $390,000 or $0.05 per share.

FAIR VALUE OF FINANCIAL INSTRUMENTS

    Carrying amounts of financial instruments held by the Company, which include
cash equivalents, accounts receivable, other current assets, accounts payable,
accrued expenses and deferred revenues, are reflected in the accompanying
consolidated financial statements at fair value due to the short-term nature of
those instruments. The carrying amount of long-term debt approximates its fair
value.

IMPAIRMENT OF LONG-LIVED ASSETS

    The Company accounts for its long-lived assets in accordance with Statement
of Financial Accounting Standard ("SFAS") No. 121, "Accounting for the
Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed Of."
The Company reviews its long-lived assets, including property and equipment,
goodwill and customer list, for impairment whenever events or changes in
circumstances indicate that the carrying amount of the assets may not be fully
recoverable. To determine recoverability of its long-lived assets, the Company
evaluates the probability that future undiscounted net cash flows will be less
than the carrying amount of the assets. Impairment is measured at fair value.
There were no such asset impairments at December 31, 1999.

REVENUE RECOGNITION

    Service revenues include one-time and ongoing charges to customers for
accessing the Internet. One-time charges relate to porting, initial connection
or other related fees and are recognized as revenue when the Company completes
the process, typically when the customer is set up for initial or expanded
service. The Company recognizes ongoing access revenue over the period the
services are provided. The Company offers contracts for Internet access that are
generally paid for in advance by customers. The Company has deferred revenue
recognition on these advance payments and recognizes this revenue ratably over
the service period.

    Revenues are also derived from the resale of products, including hardware
and software, and web hosting services. The Company recognizes product sales
revenue when the equipment is shipped to the customer. The Company sells its web
hosting and related services for contractual periods ranging from one to twelve
months. These contracts generally are cancelable by either party without
penalty. Revenues from these contracts are recognized ratably over the
contractual period as services are provided. Incremental fees for excess
bandwidth usage and data storage are billed and recognized as revenues in the
period in which customers utilize such services. Revenues include network
installation, maintenance and consulting services. These services are provided
on a time-and-material basis and revenues are recognized based upon time (at
established rates) and other direct costs as incurred.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)
ADVERTISING

    All advertising costs are expensed as incurred. Advertising expense for the
years ended December 31, 1997, 1998 and 1999 was $243,104, $625,264 and
$1,046,181, respectively.

COST OF REVENUES

    Cost of revenues includes telecommunications charges and other charges
incurred in the delivery and support of services, including personnel costs in
the Company's operations support function, as well as equipment costs related to
hardware and software sales. The telecommunications component of cost of
revenues was $1,318,021, $2,091,772 and $4,528,908 for the years ended
December 31, 1997, 1998 and 1999, respectively.

INCOME TAXES

    The Company accounts for income taxes in accordance with SFAS No. 109,
"Accounting for Income Taxes." Under SFAS No. 109, deferred tax assets and
liabilities are determined based on differences between the financial reporting
and tax bases of assets and liabilities and are measured using enacted tax rates
that are expected to be in effect when the differences reverse.

    At December 31, 1999, the Company had a net operating loss carryforward for
federal income tax purposes of approximately $6,137,000. The net operating loss
carryforward will begin to expire in 2010. The Company's utilization of its loss
carryforward could be limited pursuant to the Tax Reform Act of 1986, due to
cumulative changes in ownership in excess of 50%.

    The Company has a net deferred tax asset primarily related to the net
operating loss carryforward and timing differences between the financial
reporting and tax accounting treatment of certain expenses. Due to the Company's
history of operating losses, the realization of the deferred tax asset is
uncertain therefore, the Company has provided a full valuation allowance against
the net deferred tax asset.

NET LOSS PER COMMON SHARE

    The Company has presented net loss per share pursuant to SFAS No. 128,
"Earnings per Share." Basic loss per share was computed by dividing net loss by
the weighted average number of shares of Common stock outstanding during the
period. Diluted loss per share is the same as basic loss per share because the
impact on loss per share using the treasury stock method is antidilutive due to
the Company's losses.

MAJOR CUSTOMERS

    The Company derived revenues of approximately 24% and 13% from its two
largest customers for the year ended December 31, 1997, 11% from its largest
customer for the year ended December 31, 1998 and 21% from its largest customer
for the year ended December 31, 1999.

    Financial instruments that potentially subject the Company to concentration
of credit risk consist principally of cash balances and trade receivables. The
Company invests its excess cash with federally insured banks. The Company does
not require collateral from its customers.

SUPPLEMENTAL CASH FLOW INFORMATION

    For the years ended December 31, 1997, 1998, and 1999, the Company paid
interest of $36,281, $171,101 and $317,443, respectively. For the years ended
December 31, 1997, 1998 and 1999, the Company paid income taxes of $23,069,

NEW ACCOUNTING PRONOUNCEMENTS

    In December 1999, the Securities and Exchange Commission issued Staff
Accounting Bulletin ("SAB") No. 101, "Revenue Recognition in Financial
Statements." The bulletin draws on existing accounting rules and provides
specific guidance on how those accounting rules should be applied. SAB 101 is
effective for fiscal years beginning after December 15, 1999. The Company is
currently evaluating the impact that SAB No. 101 may have on its consolidated
financial statements and related disclosures.

3. ACQUISITION:

    On July 30, 1999, the Company acquired 100% of the capital stock of Internet
Unlimited, Inc., a provider of web hosting and colocation services, for $400,000
in cash and 546,984 shares of Common stock with transaction costs of $75,000.
The results of operations from the acquired business have been included in the
consolidated financial statements from the date of acquisition. The Company
recorded the acquisition using the purchase method of accounting pursuant to
Accounting Principles Board ("APB") No. 16, "Accounting for Business
Combinations." The excess of the purchase price over the fair value of net
liabilities was determined to be $4,462,498. Of this amount $2,462,498 was
allocated to goodwill and $2,000,000 was allocated to customer list. The
customer list and goodwill are being amortized on a straight-line basis over
3 years. If the acquisition of Internet Unlimited Inc. had occurred on
January 1, 1998, the unaudited pro forma information, after giving effect to the
pro forma adjustments described below, would have been as follows:

    The unaudited pro forma information does not purport to be indicative of the
results that would have been attained if the operations had actually been
combined for the periods presented and is not necessarily indicative of the
operating results to be expected in the future. The pro forma adjustments
consist of the amortization of customer list and goodwill of $1,487,500 for the
year ended December 31, 1998 and $1,487,500 (including $619,791 recorded by the
Company in August through December 1999) for the year ended December 31, 1999.
Additionally, prior to the acquisition, the Company derived revenues from
Internet Unlimited, Inc. These revenues and the corresponding costs of revenues
recorded by Internet Unlimited, Inc. have been eliminated from the above
unaudited information.

    On May 28, 1998, the Company sold a $3,050,000 convertible note (the
"Convertible Note"), and a warrant to purchase 1,000,000 shares of Common stock
at an exercise price of $1.50 per share to an investor. The investor also
purchased 1,000,000 shares of Common stock (see Note 7). The Black-Scholes
pricing model calculated a minimal value for the warrant; therefore, no proceeds
were assigned to the warrant.

    The Convertible Note bears interest at 7% and is convertible into Common
stock at the option of the investor at any time prior to maturity at $1.50 per
share subject to adjustment, as defined. The Convertible Note is secured by
substantially all of the assets of the Company. Interest on the Convertible Note
is payable quarterly in arrears. The Convertible Note originally matured on
November 30, 1999. On August 9, 1999, the investor agreed to extend the maturity
of the Convertible Note to January 31, 2001. The investor also agreed to convert
the Convertible Note into 2,033,334 shares of Common stock immediately prior to
the consummation of the initial public offering. The

Convertible note was converted to Common stock upon the consummation of the
initial public offering (see Note 10).

    On May 14, 1999, the Company sold a $1,000,000 convertible note to an
investor (the "May 14th Convertible Note"). The May 14th Convertible Note bore
interest at 7%, and both principal and accrued interest were convertible at the
option of the holder at any time prior to maturity at rates subject to
adjustment based on the future sales price of the Company's Common stock. In
August 1999, this investor converted the May 14th Convertible Note together with
accrued and unpaid interest on the note into 142,431 shares of Series A
Preferred. The shares of Series A Preferred converted to Common stock upon the
consummation of the initial public offering (see Note 10).

    In 1997, the Company received a $21,873 term note from a financing company,
bearing interest at 10.75%. The outstanding balance at December 31, 1999 was
$9,909.

    In 1998, the Company received a $44,000 term note from a bank, bearing
interest at 9%. The outstanding balance at December 31, 1999 was $34,710. Future
maturities on this term note are $8,200, $8,969, $9,811, and $7,730 and are due
in 2000, 2001, 2002, and 2003, respectively.

    In 1998, the Company received a $250,000 note from a customer bearing 7.5%
interest. The note was paid off in May 1998.

    In 1997, the Company issued a $200,000 demand note bearing 8.0% interest to
a company controlled by a shareholder of FASTNET. The note was repaid in
May 1998 with the proceeds from the Convertible Note.

7. SHAREHOLDERS' EQUITY:

COMMON STOCK

    The Company has 50,000,000 authorized shares of no par value Common stock.
The Company had 7,000,000 shares outstanding on December 31, 1998 and 7,546,984
shares outstanding on December 31, 1999.

    In May 1998, the Company purchased 5,787,610 shares of Common stock from
certain employee shareholders (the "Sellers") of the Company. Subsequently in
May 1998, the Company sold 1,000,000 shares to an investor. The Company recorded
the purchase from the Sellers as a purchase of treasury stock. Also, in
May 1998, the investor purchased a $3,050,000 note from the Company and received
a warrant to purchase 1,000,000 shares of Common stock. Also in May 1998, the
Company issued 212,390 shares of fully vested Common stock to certain employees.
In connection with issuing these vested shares, the Company charged $42,478 to
compensation expense, the value of the 212,390 shares. This expense is included
within selling, general and administrative expenses in the accompanying
consolidated statements of operations.

PREFERRED STOCK

    The Company has 10,000,000 authorized shares of no par value Preferred
stock. The Company designated and issued 808,629 shares as Series A Convertible
Preferred stock ("Series A Preferred") in August 1999. The Series A Preferred is
convertible at any time into Common stock of the Company at

a one-for-one conversion ratio. The holders of the Series A Preferred have a
liquidation preference of $7.13 per share.

    In August 1999, the Company sold 666,198 shares of Series A Preferred to
certain investors at $7.13 per share. In connection with the sale of Series A
Preferred, an advisory fee of $285,000 is due to the financial advisor, who is
an affiliate of a significant shareholder. The proceeds from the sales of the
Series A Preferred were $4,445,108, net of offering costs of $304,884. The
Series A Preferred converted into Common Stock immediately prior to the
consumation of the Company's initial Public Offering (see Note 10).

COMMON STOCK OPTIONS

    In March 1999, the Company approved the 1999 Equity Compensation Plan (the
"1999 Plan"). The 1999 Plan provides for the issuance of up to 1,000,000 shares
of Common stock for incentive stock options ("ISOs"), nonqualified stock options
("NQSOs") and restricted shares. ISOs are granted with exercise prices at or
above fair value as determined by the Board of Directors. NQSOs are granted with
exercise prices determined by the Board of Directors. Each option expires on
such date as the Board of Directors may determine, generally ten years.

    The Company applies APB Opinion No. 25, "Accounting for Stock Issued to
Employees," and the related interpretations in accounting for options issued to
employees under the 1999 Plan. Accordingly, compensation expense is recognized
for the intrinsic value (the difference between the exercise price and the fair
value of the Company's stock) on the date of grant. Compensation, if any, is
deferred and charged to expense over the respective vesting period. In May and
June 1999, the Company issued options to purchase 110,000 and 3,000 shares of
Common stock, respectively for $2.50 per share. At that time the fair value of
the Company's Common stock was deemed $7.13 per share. These options vest over
periods ranging from one to five years. In connection with these option grants,
the Company recorded deferred compensation of $532,450 for the year ended
December 31, 1999. The amortization expense as a result of the amortization of
the deferred compensation was $168,301 in the same period.

    Under SFAS No. 123, "Accounting for Stock-Based Compensation," compensation
cost related to stock options granted to employees is computed based on the
value of the stock option at the date of grant using an option valuation
methodology, typically the Black-Scholes pricing model. SFAS No. 123 can be
applied either by recording the fair value of the options or by continuing to
record the APB No. 25 value and disclosing the SFAS No. 123 impact on a pro
forma basis. The Company has elected the disclosure method of SFAS No. 123. Had
compensation cost of the Company's 1999 Plan been determined based upon the fair
value of the options at the date of grant, as prescribed under SFAS No. 123, the
Company's net loss for the year ended December 31, 1999 would have increased by
$296,864.

    The weighted average fair value of the options granted during 1999 is
estimated at $2.11 using the Black-Scholes pricing model with the following
assumptions: dividend yield of zero; volatility of 70%; weighted average
risk-free interest rate of 5.55% and an expected life of six years.

    As of December 31, 1999, there were exercisable options to purchase an
aggregate of 295,000 shares at an average exercise price of $1.52 per share. The
weighted average remaining contractual life of all options outstanding at
December 31, 1999 is 9.24 years.

WARRANTS

    In May 1998, the Company issued a warrant to an investor to purchase
1,000,000 shares of Common stock at an exercise price of $1.50 per share. This
warrant is currently exercisable and expires in May 2005.

8. COMMITMENTS AND CONTINGENCIES:

LEASES

    In June 1999, the Company entered into a $20 million master equipment lease
agreement with an equipment vendor. Leases under the agreement are payable in
three monthly installments of 0.83% of the value of the equipment leased and
33 monthly installments of 0.0345% of the value of the equipment leased. As of
December 31, 1999, the Company had $16,348,133 available for the purchase of
additional equipment under the lease.

    The Company leases office space, telecommunications services and equipment

                       FASTNET CORPORATION AND SUBSIDIARY

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

8. COMMITMENTS AND CONTINGENCIES: (CONTINUED)
LITIGATION

    From time-to-time, the Company is involved in certain legal actions arising
in the ordinary course of business. In the Company's opinion, based on the
advise of counsel, the outcome of such actions will not have a material adverse
effect on the Company's future financial position or results of operations.

RELATED PARTY TRANSACTION

    In June 1999, the Company entered into a financial arrangement, as amended,
with an advisor (the "Financial Advisor"), who is an affiliate of a significant
shareholder. This agreement provided for a payment of $320,000 to be made to the
Financial Advisor on February 1, 2001 related to the private placement of
securities, and a $500,000 payment due upon the earlier of the consummation of
an initial public offering or February 1, 2001. This $500,000 payment is related
to general strategic and advisory services rendered during the three months
ended September 30, 1999. The $500,000 was repaid March 2, 2000 with a portion
of the proceeds from the initial public offering.

    In January 2000, the Company received a $1,000,000 promissory note from the
Financial Advisor, bearing interest at 7%. This promissory note was repaid upon
the consummation of the initial public offering (see Note 10).

9. RETIREMENT SAVINGS PLAN

    In 1999, the Company established a defined contribution 401(k) retirement
savings plan, which covers substantially all employees. Employees become
eligible to participate in the plan upon six months of employment. Employees may
elect to contribute up to 15% of their annual compensation up to the maximum
allowable under the Internal Revenue Code. The Company matches $0.50 on every
$1.00 up to the first 6% of the employee contributions. The Company made $72,036
of contributions in 1999.

10. SUBSEQUENT EVENT:

    On February 7, 2000, the Company completed its initial public offering of
4,000,000 shares of Common stock at a price of $12.00 per share raising net
proceeds of approximately $43,040,000. Additionally, on March 7, 2000, the
underwriters exercised their over-allotment option for the purchase of 600,000
shares at a price of $12.00 per share. The Company received net cash proceeds of
approximately $6,696,000 from the exercise of the underwriters over-allotment
option. Additionally, immediately prior to the consummation of the initial
public offering the Convertible Note converted into 2,033,334 shares of Common
stock (see Note 6); and 808,629 shares of Series A Preferred converted to Common
stock (see Note 7).
