ITEM 1. BUSINESS

Overview

PART I

We  are a leading facilities-based provider of low-cost, high-speed Internet access and Internet
Protocol, or IP, communications services. Our network  is specifically designed and optimized  to  transmit
data using IP. We deliver our services  primarily to small and  medium-sized  businesses, communications
service providers and other bandwidth-intensive organizations through approximately 25,000 customer
connections in North America and Europe.

Our on-net service consists of high-speed Internet access and IP connectivity ranging from 0.5
Megabits per second to 10 Gigabits per second  of  bandwidth. We  offer our on-net  services  to  customers
located in buildings that are physically  connected to our network.  Because of our integrated network
architecture, we are not dependent on local telephone companies  to  serve  these on-net  customers.  We
provide on-net Internet access to net-centric  and  corporate  customers. Our primary on-net service
offered to our corporate customers is  Internet access at a speed of 100 Megabits per second. Our
corporate customers are located in multi-tenant office  buildings and typically include law firms,
financial services firms, advertising and  marketing firms and other professional services businesses.  Our
on-net services offered to our net-centric  customers include Internet  access at speeds  of ten Gigabits
per  second. Our net centric customers  include certain  bandwidth-intensive users such as universities,
other Internet service providers, telephone companies, cable television companies and  commercial
content providers. These customers generally receive service in colocation facilities and  in our data
centers. For the years ended December  31, 2008, 2009 and 2010,  our on-net  customers generated
81.7%, 79.9% and 77.8%, respectively,  of  our total service revenue.

Our off-net services are sold to businesses that are  connected to our  network primarily by means
of ‘‘last mile’’ access service lines obtained from  other carriers, primarily in the  form of point-to-point
TDM, POS, SDH  and/or Carrier Ethernet circuits. For the years ended December 31,  2008, 2009 and
2010, our off-net customers generated 16.1%,  18.4%, and  21.0%, respectively, of our total service
revenue.

Our non-core services, which consist  primarily of legacy  services of companies whose assets  or
businesses we have acquired and continue to support  but do not actively sell, primarily include  dial-up
Internet access services and voice services (only  provided in  Toronto, Canada). For the years ended
December 31, 2008, 2009 and 2010, non-core services generated  2.2%,  1.7% and 1.2%, respectively, of
our  total service revenue.

We  also operate 41 data centers comprising  over 369,000 square feet throughout North America

and Europe that allow customers to co-locate their equipment  and  access our network.

Competitive Advantages

We  believe we address many of the IP data communications needs  of small and medium-sized
businesses, communications service providers and other bandwidth-intensive organizations  by  offering
them high-quality Internet service at  attractive prices.

Low  Cost of Operation. We offer a streamlined set of products on an integrated network that

operates on a single protocol. Our network design allows  us  to  avoid many of  the costs that our
competitors incur associated with circuit-switched and  TDM networks  related to provisioning,
monitoring and maintaining multiple transport protocols.  We believe that our low  cost of operation also
gives us greater pricing flexibility and a significant advantage in  a competitive environment
characterized by falling Internet access prices. We believe our value proposition is equal or superior to

2

our  competitors’ in all on-net multi-tenant office buildings  and carrier  neutral  data  centers  in which we
compete.

Independent Network. Our on-net service does not rely on infrastructure controlled by  a third
party carrier. In on-net multi-tenant office  buildings  we  provide our  customers  the entire network,
including the last mile and the in-building wiring  to  the customer’s  suite.  In carrier neutral  data  centers
we are colocated with our customers so  only  a connection within-the-data center  is required to provide
our services. This gives us more control over our service, quality  and pricing. It  also allows us to
provision services more quickly and efficiently  than provisioning services on  a third party carrier
network. We are typically able to activate service to our customers in  one of our on-net buildings  in
approximately ten business days.

High Quality, Reliable Service. We are able to offer high-quality Internet service due to our
network (created solely to transmit IP  data) and  our dedicated intra-city bandwidth for each customer.
This design increases the speed and  throughput of our  network and reduces the number of data
packets dropped during transmission  compared to traditional circuit-switched networks. We believe that
we deliver a high level of technical performance because our network is optimized for IP traffic. We
believe that our network is more reliable and delivers IP  traffic at lower cost than networks  built as
overlays to traditional circuit-switched  networks.

High Traffic Network Footprint. We have strategically chosen locations, such as  large  multi-tenant
office buildings in major cities and colocation  facilities with high  levels of Internet traffic, to maximize
our  revenue opportunities and expand our margins. Our network  is connected to our on-net multi-
tenant  office buildings where we offer our services to a diverse  set of high-quality, low  churn  customers
within close physical proximity of each other. Our network is also  directly connected to over 490  carrier
neutral colocation and data centers where our  net-centric customers directly interconnect  with our
network.

Low  Capital Cost to Grow Our Business. We have a history of efficient network expansion and

integration execution. We believe that  we  have incurred relatively lower costs in growing our business
than our competitors because we use  Internet routers without additional legacy equipment and have
acquired optical fiber from the excess capacity  in  existing networks.

Next Generation IP-Based Network. We believe that there is a clear industry  and market trend  for
legacy products (e.g., TDM voice, Private Line,  Frame Relay, and ATM) to be replaced with IP-based
services. Many of our competitors may  need  to  migrate their existing customers  and products to IP in
the near future. Given our next generation IP network,  we benefit from this trend. This migration can
be costly, time consuming and risky. We do not face this challenge because  our network and products
are already IP-based. In addition, we  believe  there is a trend away from  private networks to the use of
the public Internet for communications services.  Our focus has been and continues to be providing
services that make use of the public Internet.

Proven and Experienced Management  Team. Our senior management team is composed of

seasoned executives with extensive expertise in the telecommunications industry as well as knowledge of
the markets in which we operate. The members  of  our senior management  team have an average of
over 20 years of experience in the telecommunications industry and have been working  together  at
Cogent for several years. Several members of the senior management team  have been working together
at Cogent since 2000. Our senior management team has designed and  built our  network and led the
integration of our  network assets, customers  and  service offerings we acquired through 13 significant
acquisitions.

Our Strategy

We  intend to become the leading provider  of high-quality Internet  access and IP communications

services and to continue to improve our profitability and cash flow. The principal  elements of our
strategy include:

Focus on Providing Low-Cost, High-Speed Internet Access and IP  Connectivity. We intend to further

load  our high-capacity network to respond to the growing demand for  high-speed  Internet service
generated by  bandwidth-intensive applications such  as streaming media, online gaming, video, voice
over IP (VOIP), remote data storage,  distributed  computing  and  virtual private  networks. We intend to
do so by continuing to offer our high-speed and high-capacity services  at competitive  prices.

Pursuing  On-Net Customer Growth. We intend to increase usage of our network  and operational

infrastructure by adding customers in our  existing on-net buildings, as  well as adding multi-tenant office
buildings and carrier neutral data centers to our network. Our on-net service generates greater profit
margins and more control over service levels,  quality, pricing and faster provisioning of services than
our  off-net services. Our fiber network  connects directly to on-net customers’ premises and we pay no
local access (‘‘last mile’’) charges to other  carriers.  We  are responding to this on-net revenue
opportunity by increasing our sales and  marketing  efforts including  increasing  our  number of sales
representatives and implementing strategies to optimize sales productivity.

Selectively Pursuing Acquisition Opportunities.

In addition to adding customers through our sales

and marketing efforts, we will continue to seek out  acquisition  opportunities that increase  our customer
base, allowing us to take advantage of the  unused  capacity on  our network and to add revenues with
minimal incremental costs. Given our record of successful asset integration,  we believe  we can continue
to successfully integrate new businesses as  they are acquired. We may  also make acquisitions of
network assets at attractive prices.

Our Network

Our network is comprised of in-building  riser facilities, metropolitan optical networks,  metropolitan

traffic aggregation points and inter-city  transport facilities. We believe that  we deliver a high level of
technical performance because our network is  optimized for IP  traffic.  We believe that our  network is
more reliable and delivers IP traffic at  lower cost  than networks built as overlays to traditional  circuit-
switched telephone networks.

Our network serves over 160 metropolitan markets in  North  America and Europe  and

encompasses:

(cid:127) over 1,115 multi-tenant office buildings strategically located in commercial  business  districts;

(cid:127) over 490 carrier-neutral Internet aggregation  facilities,  data centers  and  single-tenant buildings;

(cid:127) over 390 intra-city networks consisting of over 15,500 fiber miles;

(cid:127) an inter-city network of more than 51,200 fiber route miles; and

(cid:127) multiple high-capacity transatlantic circuits that connect  the North  American and  European

portions of our network.

We  have created our network by acquiring optical  fiber from carriers  with large amounts  of  unused

fiber and  directly connecting Internet routers to our existing optical fiber national backbone. We have
expanded our network through key acquisitions  of  financially distressed  companies or their assets at a
significant discount to their original cost.  Due to our network design and acquisition strategy, we
believe we are positioned to grow our  revenue and increase our profitability  with limited incremental
capital expenditures.

4

Inter-city Networks

Our inter-city network consists of optical  fiber connecting major  cities  in North  America and
Europe. The North American and European  portions of our network  are connected  by  transatlantic
circuits. Our network was built by acquiring from various owners of fiber optic networks the right to
use typically two strands of optical fiber  out of the multiple fibers owned by  the carrier. We install the
optical and electronic equipment necessary  to  amplify, regenerate,  and route the  optical signals  along
these networks. We have the right to  use  the optical fiber  under long term agreements.  We pay these
providers fees for the maintenance of  the optical fiber  and provide our  own equipment maintenance.

Intra-city Networks

In each metropolitan area in which we provide our  high-speed on-net Internet access services, our

backbone network is connected to one or more routers  that  are  connected  to  one or more of our
metropolitan  optical networks. We create  our intra-city  networks by obtaining the  right to use  optical
fiber from carriers with optical fiber networks  in those cities. These metropolitan  networks consist of
optical fiber that runs from the central  router  in a market  into routers located in  our on-net  buildings.
In most cases the metropolitan fiber  runs  in  a ring architecture,  which provides redundancy  so that if
the fiber is cut, data can still be transmitted to the central  router by directing traffic in the opposite
direction around the ring. The router  in the  building provides the connection to each of  our on-net
customers.

Within the cities where we offer our off-net Internet  access  services, we lease circuits from
telecommunications carriers, primarily local telephone companies, to provide the last mile connection
to our customer’s premises. Typically, these  circuits are aggregated at various locations in those cities
onto higher-capacity leased circuits that  ultimately  connect the local aggregation  route to our network.

In-Building Networks

In office buildings where we provide  service  to  multiple tenants we connect  our  routers to a cable
typically containing 12 to 288 optical  fiber strands that run  from  our equipment in  the basement of the
building through the building riser to  the customer  location. Our  service is initiated by connecting  a
fiber optic cable from our customer’s local area network  to the infrastructure in the  building riser. Our
customer then has dedicated and secure access to our network using an Ethernet connection. We
believe that Ethernet is the lowest cost  network connection technology and is  used  almost universally
for the local area networks that businesses operate.

Internetworking

The Internet is an aggregation of interconnected networks. We have  settlement -free
interconnections between our network  and  most major Internet Service Providers,  or ISPs. We
interconnect our network through public and private peering  arrangements. Public peering is the  means
by which ISPs have traditionally connected  to  each  other at  central,  public  facilities.  Larger  ISPs also
exchange traffic and interconnect their networks  by means of direct private connections referred to as
private  peering.

Peering agreements between ISPs are necessary in order  for them  to  exchange traffic. Without
peering agreements, each ISP would  have to buy Internet access from every other  ISP  in order for  its
customer’s traffic, such as email, to reach  and be received from customers of other ISPs. We are
considered a Tier 1 ISP and, as a result, we  have settlement-free peering arrangements with  other
providers. This allows us to exchange  traffic with those  ISPs without payment  by  either party. In such
arrangements, each party exchanging traffic  bears its own  cost of delivering traffic to the point  at which
it is handed off to the other party. We also engage in public peering arrangements in which each party
also pays a fee to the owner of routing  equipment that  operates as the central exchange for all the

5

participants. We do not treat our settlement-free  peering arrangements as generating revenue or
expense related to the traffic exchanged.  However, we charge customers  for transit services across our
network. We directly connect with over  3,500  total  networks.

Network Management and Control

Our primary network operations centers are located  in Washington, D.C.  and Madrid, Spain. These

facilities provide continuous operational support in both North America and  Europe. Our network
operations centers are designed to immediately  respond  to any problems in our network. To ensure  the
quick replacement of faulty equipment  in  the intra-city and  long-haul networks, we have deployed  field
engineers across North America and  Europe. In addition, we have maintenance contracts with  third
party vendors that specialize in optical  and  routed  networks.

Our Services

We  offer our high-speed Internet access and  IP connectivity primarily to small  and medium-sized

businesses, communications providers  and  other  bandwidth-intensive organizations  located  in North
America and Europe.

We  offer on-net services in over 160  metropolitan markets. We  serve over 1,580 buildings of  which

more than 1,330 are located in North America with the remainder  located in Europe. Our  most
popular on-net service in North America is  our  Fast  Ethernet  service, which provides  Internet access at
100 megabits per second. We typically  offer  our Fast Ethernet (Internet access) service to our  small and
medium-sized business customers. We  also  offer Internet access services at higher speeds of  up to ten
Gigabits per second. These services are  generally used by customers that have businesses, such as web
hosting, that are Internet based and are generally delivered at data centers and carrier hotels. We
believe that, on a per-Megabit basis,  this  service offering is one  of  the lowest priced in  the marketplace.
We  also offer colocation services in 41  locations in North America and Europe. This service offers
Internet access combined with rack space  and power in a Cogent facility,  allowing the customer to
locate a server or other equipment at that  location and  connect to our Internet service. Our final
on-net service offering is our ‘‘Point-to-Point’’ or ‘‘Layer 2’’ service.  These point-to-point connections
span North America and Europe and allow customers to connect geographically dispersed local area
networks in a seamless manner. We offer  lower prices  for  longer term and volume commitments. We
emphasize the sale of our on-net services  because  we believe that  we  have a competitive advantage in

6

providing these services and these services generate greater gross  profit  margins than our off-net
services.

We  offer our off-net services to customers that are not located in our  on-net  buildings. These
services are primarily provided in the  metropolitan markets in  North America and  Europe in which we
offer on-net services. These services are generally provided to small  and medium-sized businesses  in
approximately 3,430 off-net buildings.

We  support certain non-core services that we  assumed with  certain of our acquisitions. These
services primarily include dial-up Internet  access services and voice services (only provided in Toronto,
Canada). We expect that the revenue from our non-core services will decline. We do not actively  sell
these services and expect the growth of our Internet access services to compensate  for this loss.

Sales and Marketing

Sales. We employ a direct sales and marketing approach  including telesales.  As of February  1,
2011, our sales force included 311 full-time employees. Approximately one-third  of these  employees are
located in our call centers with the remaining two-thirds located in our  sales  offices. Our outside  direct
sales personnel work through direct face-to-face contact  with potential customers in, or  intending to
locate in, our on-net buildings. Through  agreements with  building owners, we  are able  to  initiate and
maintain personal contact with our customers by staging various promotional and social events in  our
on-net buildings. Direct sales personnel are compensated with a base salary plus  quota-based
commissions and incentives. We use  a  customer  relationship management system to efficiently track
sales activity levels and sales productivity.

Marketing. Because of our focus on a direct sales force,  we have  not  spent funds  on television,

radio or print advertising. Our marketing  efforts  are designed  to  drive awareness of our products  and
services, identify qualified leads through various direct  marketing  campaigns and provide our sales force
with product brochures, collateral materials, in building  marketing  events and relevant sales tools  to
improve the overall effectiveness of our sales organization.  In  addition, we conduct public relations
efforts focused on cultivating industry analyst  and media relationships  with the goal of securing  media
coverage and public recognition of our Internet communications  services.  Our marketing organization is
responsible for our product strategy and direction based upon  primary  and secondary  market research
and the advancement of new technologies.

Competition

We  face competition from incumbent  carriers, Internet service providers and facilities-based

network operators, many of whom are  much  larger than us, have significantly greater financial
resources, better-established brand names and large, existing  installed customer bases in the  markets in
which  we compete. We also face competition from other new  entrants to the communications  services
market. Many of these companies offer products  and services  that are similar to our products and
services. Unlike some of our competitors,  we do not have title to most of the  dark  fiber that makes up
our  network. Our interests in that dark  fiber are in  the form of long-term  leases under  indefeasible
rights of use or IRUs. We rely on the  third-party maintenance of such dark fiber to provide our on-net
services to customers. We are also dependent on third party providers, for the local loop facilities for
the provision of connections to our off-net customers.

We  believe that competition is based on  many  factors, including price,  transmission speed,  ease of

access and use, breadth of service availability, reliability of service, customer support and brand
recognition. Because our fiber optic  networks  have been recently installed compared  to  those of the
incumbent carriers, our state-of-the-art  technology may provide us with  cost, capacity, and service
quality advantages over some existing incumbent carrier networks; however, our network may  not
support some of the services supported  by  these legacy networks,  such as  circuit-switched  voice,  ATM

7

and frame relay. While the Internet access speeds offered by traditional  ISPs serving multi-tenant office
buildings typically do not match our on-net offerings, these slower  services are usually priced lower
than our offerings and thus provide competitive pressure on  pricing,  particularly for more price-
sensitive customers. These and other  downward  pricing pressures particularly in carrier neutral  data
centers have diminished, and may further diminish,  the competitive advantages that we have enjoyed  as
the result of our service pricing.

Regulation

In the United States, the Federal Communications Commission (FCC) regulates common carriers’

interstate services and the state public utilities commissions exercise jurisdiction over  intrastate basic
telecommunications services. Our Internet  service  offerings are not currently regulated  by  state public
utility commissions. The FCC recently promulgated rules intended  to  regulate some aspects of  the way
traffic is handled by Internet service providers. We may become subject  to  additional regulation  in the
U.S. at the federal and state levels and  in other countries. These regulations change  from time  to  time
in ways that are difficult for us to predict.

In the United States, we are subject to the obligations set forth in  the Communications  Assistance

for Law Enforcement Act, which is administered by  the FCC. That law requires  that  we be able to
intercept communications when required to do so by law enforcement  agencies. We are required  to
comply  or we may face significant fines and penalties. We are subject to similar requirements  in other
countries.

There is  no current legal requirement that owners  or managers  of commercial office  buildings give
access to competitive providers of telecommunications  services,  although the  FCC does prohibit carriers
from entering contracts that restrict the  right  of  commercial multiunit  property owners  to  permit any
other common carrier to access and serve  the property’s commercial tenants.

Our subsidiary, Cogent Canada, offers voice and Internet services  in Canada. Generally, the
regulation of Internet access services and competitive  voice services has been  similar in Canada to that
in the U.S. in that providers of such services  face fewer  regulatory requirements than the incumbent
local telephone company. This may change. Also,  the Canadian government  has requirements limiting
foreign ownership of certain telecommunications  facilities  in Canada. We are not subject to these
restrictions today. We will have to comply with these regulations to the extent they change and to the
extent we begin using facilities in a manner  that subjects us to these restrictions.

Our European and Mexican subsidiaries operate in  more highly regulated environments  for the

types of services they provide. In many  such countries, a  national  license  or a  notice filed with  a
regulatory authority is required for the provision  of  data and Internet services. In addition, our
subsidiaries operating in member countries of the European Union are subject  to  the directives  and
jurisdiction of the European Union. We  believe  that  each of our subsidiaries has the  necessary  licenses
to provide its services in the markets  where it operates  today. To  the  extent we  expand our operations
or service offerings into new markets, in particularly in non EU member countries,  we may face new
regulatory requirements.

The laws related to Internet telecommunications are unsettled and there  may be new legislation

and court decisions that may affect our  services and expose  us to liabilities.

Employees

As of February 1, 2011, we had 568 employees. A union  represents  twenty-three  of  our  employees

in France. We believe that we have a  satisfactory relationship with our employees.

ITEM 1A. RISK FACTORS

If our operations do not consistently produce positive cash flow  to  pay for our growth or  meet our operating
and financing obligations, and we are unable to  otherwise raise  additional  capital to meet these  needs,  our
ability to implement our business plan will be  materially and adversely affected.

We  currently generate positive cash flow from our operations. We  are  not consistently cash  flow
positive overall and we have limited  funds available to us.  If we do  not  become consistently cash flow
positive or if we acquire or invest in additional businesses, assets,  services or technologies we  may need
to raise additional capital beyond that available from  our  operating cash flow. We may  also face
unforeseen capital requirements for new technology  required to remain competitive  or to comply with
new regulatory requirements, for unforeseen  maintenance of  our network and  facilities,  and for other
unanticipated expenses associated with  running our business. In addition, if  we do not retain existing
customers or add new customers, our cash flow may be impaired and  we  may be required  to  raise
additional funds through the issuance  of  debt or equity. We cannot  assure you  that  we will have access
to necessary capital, nor can we assure you  that any such financing will be available on  terms that are
acceptable to our stockholders or us.  If  issuing equity  securities raises additional funds, substantial
dilution to existing stockholders may result.

We need to retain existing customers and continue to  add  new  customers  in  order to become consistently
profitable and cash  flow positive.

In order to become consistently profitable and  consistently cash flow positive,  we need to both
retain existing customers and continue  to  add a  large number of new customers.  The  precise  number of
additional customers required is dependent on  a number  of  factors, including the  turnover of  existing
customers, the pricing of our product offerings  and the  revenue mix among our customers. We may not
succeed in adding customers if our sales and marketing plans are unsuccessful. In addition, many of our
target customers are existing businesses  that are already purchasing Internet  access services  from one
or more providers, often under a contractual commitment. It has been our experience that such  target
customers are often reluctant to switch  providers due to costs and  effort  associated with  switching
providers. Further, as some of our customers grow larger  they may decide to build  their own Internet
networks. While no single customer accounted for more than 4.9% of our 2010  revenues, a  migration
of a few very large Internet users to their own networks or  the  loss or reduced  purchases from several
significant customers could impair our  growth,  cash flow and profitability.

Our growth and financial health are subject to a number of economic  risks.

Negative developments in the credit  and  financial markets  in the United States and worldwide
have resulted in extreme disruption, including, among other things, extreme volatility in security prices,
including our own, severely diminished  liquidity  and  credit availability,  rating downgrades  of  certain
investments and declining valuations of others. While conditions in  the capital and credit  markets  have
improved, if the capital and credit markets continue to experience volatility and the availability of funds
remains limited, it is possible that our  ability to access  the capital and  credit  markets  for significant
purchases or operations may be limited  by these conditions or  other factors at a time when  we would

9

like, or need, to do so. A prolonged downturn in the  capital or credit markets may cause us to seek
alternative sources of potentially less  attractive  financing. This could  have an impact on our ability to
react to changing economic and business conditions.

The economic downturn has significantly affected the  financial services  industry, which  includes

many  of our customers. In addition, the tightening  of  credit in financial markets potentially  adversely
affects the ability of certain of our customers to obtain financing  for their operations, and could result
in a decrease in sales to new customers  or an increase in existing  customers canceling  our  services  as
well as impact the ability of our customers  to  make payments, which would negatively  impact  our  cash
flow. We are unable to predict the likely duration and severity of  any disruption in financial markets
and adverse economic conditions in the  U.S.  and  other  countries.

Our business and operations are growing rapidly  and we may not be able to efficiently manage our growth.

We  have rapidly grown our company through network expansion and the acquisition of new
customers through our sales efforts. Our  expansion  places significant strains on our management,
operational and financial infrastructure. Our ability  to  manage our growth will be particularly
dependent upon our ability to:

(cid:127) expand, develop and retain an effective sales force and qualified personnel;

(cid:127) maintain the quality of our operations and our service offerings;

(cid:127) maintain and enhance our system of  internal controls to ensure  timely  and accurate compliance

with our regulatory reporting requirements; and

(cid:127) expand our accounting and operational information systems  in order to support our growth.

If we  fail to implement these measures  successfully, our ability to manage  our growth will  be  impaired.

We may  experience difficulties in implementing our expansion in Eastern  Europe and Mexico and may incur
related unexpected costs and regulatory  issues.

We  began to expand our network into  Eastern  Europe  in 2007 and into Mexico in 2009.  We have
experienced difficulty in acquiring dark  fiber and other  difficulties in  making our network operational
in these markets. Our expansion may  cost more than we have planned.  We  also may experience
regulatory issues. Finally, we may be unsuccessful  in selling our services  in these markets. If  we are  not
successful in developing our market presence in Eastern Europe and Mexico  our  operating results  and
growth could be adversely impacted.

We may  experience delays and additional costs in expanding our on-net buildings.

Currently, we plan on continuing to increase the  number of our carrier-neutral facilities and multi-

tenant  office buildings that are connected  to our network. We may be unsuccessful  at identifying
appropriate buildings or negotiating favorable terms  for  acquiring  access to such buildings, and
consequently, may experience difficulty in  adding customers to our network and  fully using our
network’s available capacity.

Our connections to the Internet require  us to establish and maintain relationships  with other providers, which
we may not be able to maintain.

The Internet is composed of various public and private network  providers who operate their own

networks that interconnect at public and private  interconnection  points. Our network is one such
network. In order to obtain Internet  connectivity for our network, we must establish  and maintain
relationships with other providers and incur the necessary capital  costs to locate  our  equipment and
connect our network at these various interconnection points.

10

By  entering into what are known as settlement-free peering arrangements, providers agree to
exchange traffic between their respective networks  without charging each other. Our ability to avoid the
higher  costs of acquiring paid dedicated  network capacity  and to maintain high network performance is
dependent upon our ability to establish and maintain peering relationships.  The terms and conditions
of our peering relationships may also be subject to adverse changes,  which we  may not be able  to
control. For example, several network operators with large numbers of individual users are arguing that
they should be able to charge or charge more to network operators and businesses that exchange  traffic
to those users. If we are not able to maintain or increase our peering  relationships in  all  of our  markets
on favorable terms, we may not be able  to provide  our customers with high performance or affordable
or reliable services, which could cause  us to lose existing and potential customers,  damage our
reputation and have a material adverse  effect on  our  business. We have in the past had disputes with
other network providers that resulted  in a  temporary disruption of  the  exchange of  traffic between our
network and the network of the other carrier. We have resolved the  majority of such  disputes through
negotiations. We continue to experience  resistance from  certain incumbent telephone companies,
especially in Europe, to upgrade the  settlement-free peering connections necessary to accommodate the
growth of the traffic that we exchange  with  such carriers. We cannot assure  you that we will be able  to
continue to establish and maintain relationships with  providers  or favorably resolve  disputes  with
providers.

We may  be required to censor content on the  Internet, which we may  find difficult to  do and which may
impact our ability to provide service in  some  countries as well as impact the growth of Internet  usage,  upon
which we depend.

Some governments attempt to limit access to certain content  on the  Internet. It is  impossible for

us (and other providers as far as we know) to filter  all  content that flows across the Internet
connections we provide. For example, some content  is encrypted when a secure  web site  is accessed. It
is difficult to limit access to web sites that  engage in practices that make it difficult to block them  by
blocking a fixed set of Internet addresses.  Should  a government  require  us to perform these  types of
blocking procedures we could experience difficulties  ranging  from  incurring  additional expenses to
ceasing to provide service in that country.  We could also  be subject  to  penalties if we fail to implement
the censorship.

We may  not successfully make or integrate acquisitions or enter into  strategic alliances.

As part of our growth strategy, we intend  to  pursue selected acquisitions  and strategic alliances. To

date,  we have completed 13 significant acquisitions. We compete  with other companies  for acquisition
opportunities and we cannot assure you that we  will be able to execute future acquisitions  or strategic
alliances on commercially reasonable terms, or  at all. Even if we enter  into these transactions, we may
experience:

(cid:127) delays in realizing or a failure to realize the  benefits we  anticipate;

(cid:127) difficulties or higher-than-anticipated costs associated with integrating any acquired  companies,

products or services into our existing business;

(cid:127) attrition of key personnel from acquired businesses;

(cid:127) unexpected costs or charges; or

(cid:127) unforeseen operating difficulties that require significant financial  and managerial  resources  that

would otherwise be available for the  ongoing  development or expansion of our existing
operations.

In the past, our acquisitions have often  included assets,  service offerings and financial obligations
that are not compatible with our core business strategy. We  have expended  management attention and

11

other resources to the divestiture of assets,  modification  of products  and  systems  as well as
restructuring financial obligations of  acquired operations. In most  acquisitions, we have  been successful
in renegotiating the long-term agreements that we have acquired. If we are  unable to satisfactorily
renegotiate such agreements in the future  or with respect  to future acquisitions,  we may be exposed to
large claims for payment for services  and  facilities we do not need.

Consummating these transactions could also  result in the  incurrence of additional  debt  and related
interest expense, as well as unforeseen contingent  liabilities,  all of which  could  have a material adverse
effect on our business, financial condition  and  results of operations. Because we have purchased
financially distressed companies or their assets,  and  may  continue to do so in the  future, we have not
had, and may not have, the opportunity to perform extensive due diligence or  obtain  contractual
protections and indemnifications that  are  customarily  provided  in corporate  acquisitions. As a  result, we
may face unexpected contingent liabilities  arising from these acquisitions.  We may also issue  additional
equity in connection with these transactions, which would dilute our existing shareholders.

Following an acquisition, we have experienced a decline in revenue attributable to acquired

customers as these customers’ contracts have expired and they  have entered into standard Cogent
customer contracts at generally lower rates or  have chosen  not  to  renew service  with us. We anticipate
that we will experience similar declines  with respect to customers  we may acquire  in the future.

We depend upon our key employees and may  be unable to attract or retain sufficient  qualified personnel.

Our future performance depends upon the  continued  contribution of our executive management

team and other key employees, in particular,  our Chairman and Chief Executive  Officer, Dave
Schaeffer. As founder of our company,  Mr. Schaeffer’s knowledge  of our  business  and our industry
combined with his deep involvement in every  aspect  of  our  operations and planning make him
particularly well-suited to lead our company and difficult  to  replace.

Our business could suffer because telephone  companies and  cable  companies may provide better delivery  of
Internet content originating on their own  networks.

Broadband connections provided by cable TV and telephone companies have  become the
predominant means by which consumers  connect to the Internet. The  providers  of  these  broadband
connections may treat Internet content delivered from different  sources differently. The possibility of
this  has been characterized as an issue  of  ‘‘net neutrality.’’ As many of our customers operate websites
and services that deliver content to consumers our ability  to sell our services would  be  negatively
impacted if Internet content delivered  by us was less easily received by consumers  than Internet  content
delivered by others. The U.S. Federal  Communications Commission  (‘‘FCC’’) has recently adopted
rules addressing net neutrality that it  deems necessary to ensure  continuation of an  ‘‘open’’ Internet.
We  cannot predict whether or how the  FCC’s new rules  or subsequent additions or  changes to those
rules will affect our business and operations.

Our operations outside of the United States  expose us  to economic,  regulatory and  other  risks.

The nature of our European, Canadian, and Mexican  businesses involve a number of risks,

including:

(cid:127) fluctuations in currency exchange rates;

(cid:127) exposure to additional regulatory and legal requirements, including import restrictions  and

controls, exchange controls, tariffs and other  trade barriers;

(cid:127) difficulties in staffing and managing our foreign  operations;

(cid:127) changes in political and economic  conditions; and

(cid:127) exposure to additional and potentially adverse tax regimes. 

12

As we continue to expand into other  countries, our  success will depend,  in part, on  our  ability  to
anticipate and effectively manage these  and other risks. Our  failure to manage  these risks and grow our
operations outside the U.S. may have a material adverse effect  on our business and results of
operations.

Fluctuations in foreign exchange rates may adversely affect our  financial position  and results  of operations.

Our operations outside the U.S. expose us to currency fluctuations  and exchange rate risk. For
example, while we record revenues and the financial results of our European operations in Euros, these
results are reflected in our consolidated  financial statements in  U.S.  dollars. Therefore, our reported
results are exposed to fluctuations in the  exchange rates between  the U.S.  dollar and  the Euro. We
fund certain of our cash flow requirements of  our  European, Canadian  and  Mexican operations  in U.S.
dollars. Accordingly, in the event that  their  currencies  strengthen  against  the  dollar to a greater extent
than we anticipate, the cash flow requirements associated with these operations  may be significantly
greater in U.S.-dollar terms than planned.

Our business could suffer delays and problems due  to the actions of network providers on whom we are
partially dependent.

Our off-net customers are connected  to our network by means of communications lines  that  are
provided as services by local telephone companies  and  others. We  may experience problems  with the
installation, maintenance and pricing of  these lines  and  other communications links, which could
adversely affect our results of operations  and our plans to add additional customers to our network
using such services. We have historically  experienced  installation and maintenance delays when  the
network provider is devoting resources  to  other  services, such as  traditional telephony. We have also
experienced pricing problems when a  lack  of alternatives allows  a  provider  to  charge high prices for
services in an area. We attempt to reduce this  problem by  using many different providers so that we
have alternatives for linking a customer  to our network. Competition among the providers tends to
improve installation, maintenance and  pricing.

Our network could suffer serious disruption if certain locations experience  serious damage.

There are certain locations through which a  large amount of our Internet traffic passes.  Examples

are facilities in which we exchange traffic  with other carriers,  the facilities through which our
transatlantic traffic passes, and certain of  our network hub sites.  If any  of these facilities were
destroyed or seriously damaged a significant amount of our network  traffic  could  be  disrupted. Because
of the large volume of traffic passing  through these facilities our ability  (and the ability of carriers with
whom we exchange traffic) to quickly restore service would be challenged. There could be parts of our
network or the networks of other carriers  that could  not  be  quickly  restored or that would experience
substantially reduced service for a significant  time. If  such a disruption occurs,  our reputation could be
negatively impacted which may cause  us to lose customers and  adversely affect our ability to attract
new customers, resulting in an adverse effect on our business and  operating results.

If the information systems that we depend on to support  our customers, network operations, sales, billing and
financial reporting do not perform as expected, our operations and our financial  results may be adversely
affected.

We  rely  on complex information systems to operate our network and support our other business

functions. Our ability to track sales leads,  close sales opportunities, provision services, bill our
customers for those services and prepare our financial  statements depends upon the effective
integration of our various information systems. If  our  information systems, individually or  collectively,
fail or do not perform as expected, our  ability to process and  provision orders, to make timely
payments to vendors, to ensure that we collect amounts owed  to  us and prepare  our  financial

13

statements would be adversely affected. Such failures or  delays  could result in increased capital
expenditures, customer and vendor dissatisfaction,  loss of business or the inability to add new
customers or additional services, and prepare accurate and  timely  financial statements all of which
would adversely affect our business and results of operations.

We have  historically incurred operating  losses and these losses  may  continue  for the foreseeable future.

Since we initiated operations in 2000, we  have generated operating losses and these  losses may
continue for the foreseeable future. In 2008 we had  an operating  loss of $22.2 million,  in 2009 we had
an operating loss of $3.8 million and in 2010 we had  operating income of $15.2 million.  As of
December 31, 2010, we had an accumulated  deficit of  $332.0  million.  Continued operating losses  may
prevent us from pursuing our strategies for growth  or may require  us to seek  unplanned additional
capital and could cause us to be unable  to meet our debt service obligations, capital  expenditure
requirements or working capital needs.

The utilization of certain of our net operating loss carryforwards are limited and depending upon the  amount
of our taxable income we may be subject  to  paying income taxes earlier than planned.

Due to the uncertainty surrounding the  realization of our net  deferred tax asset, we have recorded

a valuation allowance for the substantial majority of our net deferred tax asset. As of December 31,
2010, we have combined net operating loss carry-forwards  of approximately $1.1 billion.  This amount
includes federal and state net operating loss  carry-forwards in  the United  States  of approximately
$376 million, and net operating loss carry-forwards of approximately $6.2 million, $0.8  million and
$686.6 million related to our operations in Canada, Mexico  and Europe, respectively. Section  382 of
the Internal Revenue Code in the United  States limits the utilization of net operating losses when
ownership changes, as defined by that section, occur. We  have performed an analysis of our Section 382
ownership changes and have determined  that the utilization of certain of  our net operating  loss
carryforwards in the United States may  be limited.

We may  have difficulty intercepting communications as  required by the U.S. Communications Assistance  for
Law Enforcement Act and similar laws of  other countries.

The U.S. Communications Assistance for Law Enforcement  Act  and the laws of  other  countries

require that we be able to intercept communications when required to do so by law enforcement
agencies. We may experience difficulties and incur  significant costs in complying  with these laws. If we
are unable to comply with the laws we could be subject to fines in  the United States  of  up to
$1.0 million per event and equal or greater  fines in other countries.

Our business could suffer from an interruption of service from our fiber providers.

The carriers from whom we have obtained our inter-city and intra-city  dark fiber maintain that
dark fiber. We are contractually obligated  under the  agreements with  these  carriers  to  pay monthly
maintenance fees, and if we are unable to continue to pay such  monthly  fees we would be in default
under these agreements. If these carriers  fail to maintain the fiber or disrupt our  fiber connections due
to our default or for other reasons, such  as business disputes with us  and  governmental takings, our
ability to provide service in the affected  markets  or parts  of markets would be impaired unless we  have
or can obtain alternative fiber routes. The  companies  that maintain our inter-city  dark  fiber and  many
of the companies that maintain our intra-city dark fiber  are also competitors  of ours. Consequently,
they may have incentives to act in ways unfavorable to us. While we have  successfully  mitigated the
effects of prior service interruptions and  business disputes  in the past, we may incur significant delays
and costs in restoring service to our  customers in  connection with future  service  interruptions, and  as a
result we may lose customers.

14

Our business depends on agreements with  carrier neutral data center operators, which we could  fail  to obtain
or maintain.

Our business depends upon access to  customers in  carrier neutral data  centers, which  are facilities

in which many large users of the Internet house the  computer servers that deliver content and
applications to users by means of the Internet and provide  access to multiple  Internet access  networks.
Most carrier neutral data centers allow  any carrier to operate within the facility (for a  standard fee).
We  expect to enter into additional agreements with carrier neutral data center operators as part of our
growth plan. Current government regulations do not require carrier neutral data center  operators to
allow all carriers access on terms that are reasonable  or nondiscriminatory. We have been  successful in
obtaining agreements with these operators in  the past and  have generally found  that  the operators want
to have us located in their facilities because we offer low-cost, high capacity Internet service to their
other customers. Any deterioration in our existing relationships with these operators could harm  our
sales and marketing efforts and could substantially reduce our  potential customer base. Increasing
concentration in this industry, such as  the mergers between Switch  & Data Facilities  Company, Inc. and
Equinix, Inc., and Verizon Communications, Inc.  and  Terremark Worldwide, Inc. could negatively
impact us if any such combined entities  decide to discontinue operation of their facilities in  a carrier
neutral fashion.

Our ability to serve customers in multi-tenant office  buildings  depends on license  agreements with building
owners and managers, which we could fail  to obtain or  maintain.

Our on-net business depends upon our in-building networks. Our in-building networks  depend  on

access agreements with building owners or  managers  allowing us to install  our in-building  networks and
provide our services in these buildings.  These  agreements typically have terms of five to ten years, with
one or more renewal options. Any deterioration in  our existing relationships with building owners or
managers could harm our sales and marketing  efforts and  could  substantially reduce our potential
customer base. We expect to enter into  additional access  agreements as  part of our growth plan.
Current federal and state regulations do  not require  building owners  to  make  space available to us or
to do so on terms that are reasonable or  nondiscriminatory. While the FCC has adopted regulations
that prohibit common carriers under  its  jurisdiction from  entering into exclusive arrangements with
owners of multi-tenant commercial office  buildings, these  regulations do not require  building owners to
offer us access to their buildings. Building owners or managers may decide not to permit us to install
our  networks in their buildings or they may  elect  not  to  renew or amend our access agreements.  The
initial term of most of our access agreements  will  conclude in the next  several years. Most of these
agreements have one or more automatic renewal  periods and others may  be  renewed at the option of
the landlord. While we have historically been  successful in  renewing  these agreements  and no single
building access agreement is material to our  success, the failure  to  obtain or maintain a number of
these agreements would reduce our revenue, and we might not recover our costs  of procuring building
access and installing our in-building networks  in those  locations.

We may  not be able to obtain or construct additional building laterals to connect  new buildings to our
network.

In order to connect a new building to our network we  need to obtain  or construct a  lateral from
our  metropolitan network to the building.  We  may  not be able to obtain  fiber in an existing lateral at
an attractive price from a provider and may not be able to construct  our  own lateral due to the  cost of
construction or municipal regulatory restrictions. Failure to obtain fiber  in an existing  lateral or to
construct a new lateral could keep us from adding  new buildings  to  our network and negatively  impact
our  growth opportunities.

15

Impairment of our intellectual property rights and our alleged infringement  on other companies’  intellectual
property rights could harm our business.

We  are aware of several other companies in our and other industries that  use the word ‘‘Cogent’’

in their corporate names. One company  has informed us that  it believes our  use of the  name ‘‘Cogent’’
infringes  on their intellectual property  rights  in that name.  If such a challenge is  successful, we could be
required to change our name and lose the goodwill associated with  the Cogent name in  our markets.

Furthermore, we cannot assure you that the steps  taken  by us  to  protect our intellectual  property
rights will be adequate to deter misappropriation of proprietary information  or that we  will be able to
detect unauthorized use and take appropriate steps to enforce our intellectual property rights.  We also
are subject to the risk of litigation alleging  infringement of  third party  intellectual property rights. Any
such claims could require us to spend significant sums  in litigation, pay damages, develop
non-infringing intellectual property or acquire licenses  to  the intellectual property that is the  subject of
the alleged infringement.

The sector in which we operate is highly competitive, and  we may not  be  able  to  compete effectively.

We  face significant competition from incumbent carriers,  Internet service providers and facilities-

based network operators. Relative to  us,  many  of these  providers have significantly greater financial
resources, more well-established brand  names, larger customer bases,  and  more diverse strategic  plans
and service offerings.

Intense competition from these traditional and  new  communications companies  has led to

declining prices and margins for many communications  services,  and we expect this trend to continue as
competition intensifies in the future. Decreasing prices for high-speed  Internet  services have somewhat
diminished the competitive advantage  that we have  enjoyed as a result of our service pricing.

Our competitors may also introduce new technologies or  services  that could  make  our services  less

attractive to potential customers.

We issue projected results and estimates for  future periods from time to time,  and  such  projections and
estimates are subject to inherent uncertainties and may prove to  be inaccurate.

Financial information, results of operations and other projections that we may issue from time to

time are based upon our assumptions  and  estimates. While we  believe these assumptions and estimates
to be reasonable when they are developed, they are inherently subject to  significant  business,  economic
and competitive uncertainties and contingencies, many of  which are  beyond our control. You should
understand that certain unpredictable  factors could cause our  actual  results to differ from our
expectations and those differences may be material. No independent expert  participates in  the
preparation of these estimates. These  estimates should not be regarded as a representation by us as to
our  results of operations during such periods  as there  can be no assurance that any of these estimates
will be realized. In light of the foregoing,  we  caution  you not to place undue  reliance  on these
estimates. These estimates constitute forward-looking  statements.

Network failure or delays and errors in  transmissions  expose us to potential liability.

Our network is part of the Internet which is a  network of networks. Our network uses a collection

of communications equipment, software, operating protocols  and proprietary applications  for the
high-speed transportation of large quantities of data  among  multiple locations.  Given the complexity  of
our  network, it is possible that data will  be lost or  distorted. Delays in data delivery may  cause
significant losses to one or more customers using our network. Our  network  may also contain
undetected design faults and software bugs that, despite  our testing, may  not be discovered  in time  to
prevent harm to our network or to the data transmitted over it. The failure of  any equipment  or facility

16

on our network could result in the interruption  of  customer service until we affect the necessary repairs
or install replacement equipment. Network failures, delays  and errors could  also result  from natural
disasters, power losses, security breaches,  computer  viruses, denial of service attacks and  other  natural
or man-made events. Our off-net services are dependent  on the network facilities of other providers or
on local  telephone companies. Network  failures, faults or  errors could cause delays  or service
interruptions, expose us to customer  liability or  require expensive modifications that could have a
material adverse effect on our business.

As  an Internet access provider, we may incur liabilities  for information disseminated through our network.

The law relating to the liabilities of Internet access providers and  on-line  services companies for

information carried on or disseminated through their networks is  unsettled.  As the law in  this  area
develops and as we expand our international operations,  the potential imposition of liabilities  upon us
for information carried on and disseminated through our network could require us to implement
measures to reduce our exposure to such liabilities,  which may  require  the expenditure  of  substantial
resources or the discontinuation of certain products or service offerings. Any costs that are incurred as
a result of such measures or the imposition of liabilities  could harm  our business.

The holders of our senior convertible notes have the right to convert  their notes  to common stock.

The holders of our senior convertible  notes are  under certain  circumstances able  to  convert  their

notes into common stock at a conversion price of  $49.18 per  share of common stock and  to  obtain
additional shares of common stock. If  our  share  price exceeds $49.18 and the conversion rights are
exercised by the holders of the convertible notes  the number  of our  shares of  common stock
outstanding will increase which could  reduce  further appreciation  in our stock price and impact our per
share earnings. Rather than issue the  stock we are permitted to pay the cash  equivalent in  value to the
stock to be issued. We might not have sufficient funds to do this  or doing so might have  other
detrimental impacts on us.

Legislation and government regulation  could  adversely affect us.

As an Internet service provider, we are not subject to substantial regulation by the FCC  or the
state public utilities commissions in the  United States. However, the FCC has recently promulgated
limited rules applicable to Internet service providers. Internet service  is also subject  to  minimal
regulation in Western Europe and in  Canada.  In  Eastern  Europe and  Mexico the regulation is greater,
though not as extensive as the regulation  for providers of voice services. If  we decide to offer
traditional voice services or otherwise  expand our service offerings  to  include services that would  cause
us to be deemed a common carrier, we will become subject to additional  regulation. Additionally, if we
offer voice service using IP (voice over  IP) or offer certain  other types of data services using IP we  may
become  subject to additional regulation.  This regulation could impact our business because of the  costs
and time required to obtain necessary authorizations,  the additional taxes that we  may become subject
to or may have to collect from our customers,  and  the additional administrative costs  of providing  these
services, and other costs. Even if we  do  not  decide to offer additional services, governmental authorities
may decide to impose additional regulation and  taxes upon providers of Internet service. All  of  these
could inhibit our ability to remain a low  cost  carrier and  could  have a  material adverse effect on our
business, financial condition or results  of  operations.

Much of the law related to the liability of  Internet service providers remains unsettled. For
example, many jurisdictions have adopted laws related to unsolicited commercial email or  ‘‘spam’’ in
the last several years. Some jurisdictions  have  laws,  regulations, or court decisions  that  impose
obligations upon Internet access providers  to  restrict access  to  certain content. Other legal issues,  such
as the sharing of copyrighted information, transborder  data flow, universal service, and liability for
software viruses could become subjects  of  additional legislation and legal  development. We cannot

17

predict the impact of these changes on  us. Regulatory  changes could have a  material  adverse  effect  on
our  business, financial condition or results  of  operations.

Terrorist activity throughout the world,  military action to counter  terrorism  and natural disasters could
adversely impact our business.

The September 11, 2001 terrorist attacks in the  United States and the continued threat  of  terrorist

activity and other acts of war or hostility have had,  and may  continue to have, an  adverse  effect  on
business, financial and general economic  conditions internationally. Effects from these events and any
future terrorist activity, including cyber  terrorism, may, in  turn, increase our costs due to the need to
provide enhanced security, which would  adversely affect  our business and results of operations. These
circumstances may also damage or destroy  the Internet infrastructure and may adversely  affect our
ability to attract and retain customers, our  ability  to  raise capital  and  the  operation and maintenance  of
our  network access points. We are particularly vulnerable to acts  of terrorism because our largest
customer concentration is located in  New  York,  our  headquarters is in  Washington, D.C., and we have
significant operations in Paris, Madrid and London,  cities that  have historically been  targets for
terrorist attacks. We are also susceptible  to  other catastrophic events such as major natural disasters,
extreme weather, fire or similar events  that could  affect our headquarters, other offices, our network,
infrastructure or equipment, which could  adversely affect our  business.

If we do not comply with the U.S. Foreign  Corrupt Practices Act,  we may become subject to  monetary or
criminal penalties.

The U.S. Foreign Corrupt Practices Act  generally prohibits  companies and  their intermediaries

from bribing foreign officials for the purpose of obtaining or keeping business. We currently take
precautions to comply with this law. However, these precautions may  not  protect us against liability,
particularly as a result of actions that  may be taken in the  future by  agents  and other  intermediaries
through whom we have exposure under  the Foreign  Corrupt Practices Act even though  we may  have
limited or no ability to control such persons. Our  competitors  include foreign entities  that  are not
subject to the Foreign Corrupt Practices Act, and hence  we  may  be  at a  competitive disadvantage.

Risk Factors Related to Our Indebtedness

We have  substantial debt which we may  not  be  able to repay when due.

Our total indebtedness, net of discount, at  December  31, 2010 was $182.9 million.  As of

December 31, 2010, we have $92.0 million of face value of senior  convertible notes  outstanding. The
holders  of the notes have the right to  compel us  to  repurchase  for  cash on June 15, 2014,  June 15,
2017 and June 15, 2022, all or some of their notes. They also  have the right to be paid  the principal
upon default and upon certain designated events, such as  certain changes of control.  We may not have
sufficient funds to pay the principal at  the time  we are  obligated  to  do so, which could result in
bankruptcy, or we may only be able to raise the necessary  funds on unfavorable terms.

Our total indebtedness at December 31,  2010 includes $111.7 million  of  capital lease obligations
for dark fiber primarily under 15 - 20  year IRUs. The amount of  our IRU capital lease  obligations may
be impacted due to our expansion activities  and  fluctuations in foreign currency rates.

In January 2011 we issued $175.0 million in  senior secured notes due  that  are due in 2018. We

cannot guarantee that we will have sufficient funds available  to  repay the interest on  these  notes and
the principal when the notes mature.

18

Our substantial level of indebtedness could  adversely  affect our financial condition and prevent us from
fulfilling our obligations under our notes and our other indebtedness.

We  have substantial indebtedness. Our substantial debt may have important consequences. For

instance, it could:

(cid:127) make it more difficult for us to satisfy  our financial  obligations, including those relating to our

debt;

(cid:127) require us to dedicate a substantial portion of any cash flow from  operations to the payment of
interest and principal due under our debt, which will reduce  funds available for other business
purposes, including the growth of our operations,  capital expenditures and  acquisitions;

(cid:127) place us at a competitive disadvantage compared with some  of our  competitors that may have

less  debt and better access to capital resources;  and

(cid:127) limit our ability to obtain additional  financing required  to  fund working  capital and  capital

expenditures, for strategic acquisitions and for  other  general  corporate  purposes.

Our ability to satisfy our obligations and  to  reduce our total debt depends on our future operating
performance and on economic, financial, competitive and other  factors, many  of which are  beyond our
control. Our business may not generate sufficient cash flow,  and future financings  may not be available
to provide sufficient net proceeds, to meet  these obligations or to successfully execute our business
strategy.

Despite our leverage we may still be able  to  incur more debt. This could further  exacerbate the risks that we
and our subsidiaries face.

We  and our subsidiaries may incur additional  indebtedness, including  additional secured

indebtedness, in the future. The terms  of our debt indentures restrict, but do not completely  prohibit,
us from doing so. In addition, the indentures  allow us to issue additional  notes  and other  indebtedness
secured by the collateral under certain  circumstances. Moreover, we are not prevented from incurring
other liabilities that do not constitute indebtedness, including additional capital lease obligations in  the
form of IRUs. These liabilities may represent claims that  are effectively prior to the claims of our note
holders. If new debt or other liabilities are added to our debt levels the related risks that we and  our
subsidiaries now face could intensify.

The agreements governing our various  debt obligations impose  restrictions on  our  business and could
adversely affect our ability to undertake  certain  corporate actions.

The agreements governing our various debt obligations, include  covenants imposing  significant
restrictions on our business. These restrictions may affect  our ability  to  operate  our business and may
limit our ability to take advantage of potential business opportunities as they arise. These  covenants
place restrictions on our ability to, among other things:

(cid:127) incur additional debt;

(cid:127) create liens;

(cid:127) make certain investments;

(cid:127) enter into certain transactions with affiliates;

(cid:127) declare or pay dividends, redeem stock or  make other distributions to stockholders; and

(cid:127) consolidate, merge or transfer or sell all or  substantially  all of our  assets.

19

Our ability to comply with these agreements may be affected by  events beyond our control,

including prevailing economic, financial  and industry conditions. These covenants  could  have an adverse
effect on our business by limiting our ability  to  take advantage of  financing, merger and acquisition or
other corporate opportunities. The breach of any of  these  covenants  or restrictions could result in a
default under the agreements governing our debt  obligations.

To service our indebtedness, we will require a  significant amount of cash.  However, our  ability to generate
cash depends on many factors beyond our  control.

Our ability to make payments on and  to  refinance  our  indebtedness and to fund planned capital

expenditures will depend on our ability to generate  cash in  the future,  which, in  turn,  is subject  to
general economic, financial, competitive, regulatory and other factors,  many of which  are beyond our
control.

Our business may not generate sufficient cash  flow from  operations and  we may not have  available

to us future borrowings in an amount  sufficient to enable us to pay our  indebtedness or to fund our
other liquidity needs. In these circumstances, we  may  need to refinance  all  or a portion  of  our
indebtedness  on or before maturity. We  may not be able  to refinance any  of our  indebtedness on
commercially reasonable terms or at all. Without this financing,  we could be forced to sell assets  or
secure additional financing to make up for any  shortfall  in our payment  obligations under  unfavorable
circumstances. However, we may not  be  able  to  secure  additional  financing  on terms favorable to us or
at all and, in addition, the terms of the  indentures governing  our notes limit our ability to sell assets
and also restrict the use of proceeds from such a sale. We may not be able to sell assets quickly  enough
or for sufficient amounts to enable us to meet our obligations, including our obligations under our
notes.

ITEM 2. DESCRIPTION OF PROPERTIES

We  lease and own space for offices, data centers, colocation facilities, and points-of-presence.

Our headquarters facility consists of  approximately 15,370  square feet located in Washington, D.C.

The lease for our headquarters is with an entity controlled by  our Chief Executive  Officer.  The  lease
expires on August 31, 2012.

We  also lease a total of approximately 500,000 square  feet of space in 81  locations to house our

colocation facilities, corporate headquarters,  regional offices and  operations centers.  The remaining
term of these leases ranges from 3 months to 10 years with, in  many cases, options to renew.

We  believe that these facilities are generally in  good condition and  suitable  for our operations.

ITEM 3. LEGAL PROCEEDINGS

We  are involved in legal proceedings in the normal course  of our  business that we do  not  expect to

have a material adverse affect on our  business,  financial  condition or results of operations. For  a
discussion of the significant proceedings  in which we  are involved,  see Note 6 to our consolidated
financial statements.

We  have not paid any dividends on our common stock since  our inception and do not anticipate
paying  any dividends in the foreseeable future. Any future determination  to  pay dividends will  be  at the
discretion of our board of directors and  will be dependent upon then-existing conditions, including our
financial condition, results of operations, contractual restrictions, capital requirements,  business
prospects and other factors our board  of  directors  deems relevant.  We currently have no  preferred
stock outstanding.

Performance Graph

In connection with our merger with Allied  Riser  Communications Corporation, in February 2002
we began trading shares of our common  stock on the American  Stock Exchange. On March 6, 2006,
our  shares of common stock began trading  on the  NASDAQ National Market.  Our common stock
currently trades on the NASDAQ Global  Select Market.  The  chart below compares the  relative changes
in the cumulative total return of our  common  stock for  the period December 31, 2005—December  31,
2010, against the cumulative total return  for the same  period of  the  (1) The  Standard & Poor’s  500
(S&P  500) Index and (2) an industry peer group  consisting of Savvis Communications Corporation
(NASDAQ: SVVS); Internap Network  Services  Corporation (NASDAQ: INAP); and TW Telecom  Inc.
(NASDAQ: TWTC). The comparison assumes $100 was  invested  on December 31, 2005  in our
common stock, the S&P 500 Index and the industry peer  group, with  dividends,  if  any, reinvested.

ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS  OF FINANCIAL  CONDITION AND

RESULTS OF OPERATIONS

You should read the following discussion and analysis together with ‘‘Selected Consolidated  Financial

Data’’ and our consolidated financial statements and  related  notes included  in this  report. The discussion in
this report contains forward-looking statements that involve risks and uncertainties, such  as statements of
our plans, objectives, expectations and  intentions. The  cautionary statements made in this report  should  be
read as applying to all related forward-looking statements wherever  they appear in this report.  Factors that
could cause or contribute to these differences include those discussed  in ‘‘Risk Factors,’’ as well as those
discussed elsewhere. You should read ‘‘Risk Factors’’ and ‘‘Special Note  Regarding Forward-Looking
Statements.’’ Our actual results could  differ materially from those discussed here. Factors that could  cause
or contribute to these differences include, but are  not limited to:

Future economic instability in the global economy, which  could affect spending on  Internet services; the

impact of changing foreign exchange rates (in particular the  Euro-USD and Canadian—USD exchange
rates) on the translation of our non-USD denominated revenues,  expenses, assets and liabilities; legal and
operational difficulties in new markets; the  imposition of a requirement that we contribute to  the Universal
Service Fund; changes in government policy  and/or  regulation, including net neutrality rules issued by the
United States Federal Communications  Commission and in  the area of data protection; increasing
competition leading to lower prices for  our  services;  our ability to attract new customers  and to  increase and
maintain the volume of traffic on our  network; the  ability to maintain  our Internet  peering arrangements on
favorable terms; our reliance on a network equipment vendor,  and  the  potential  for hardware or  software
problems associated with such network  equipment;  the dependence of our  network on  the quality and
dependability of third-party fiber providers; our  ability to  retain  certain customers  that  comprise a significant

Commission, including, without limitation, this  annual report on  Form  10-K for the fiscal year ended
December 31, 2010.

General Overview

We  are a leading facilities-based provider of low-cost, high-speed Internet access and

IP communications services. Our network is specifically  designed and optimized to transmit  data  using
IP. IP networks are significantly less expensive to operate and are able to achieve higher  performance
levels than the traditional circuit-switched  networks  used  by many of our  competitors when  providing
Internet access services, thus, we believe, giving us  cost and performance  advantages.  We deliver our
services to small and medium-sized businesses,  communications  service providers and other bandwidth-
intensive organizations through approximately 25,000 customer  connections  in North  America and
Europe.

Our on-net service consists of high-speed Internet access and IP connectivity ranging from

0.5 Megabits per second to 10 Gigabits  per  second  of bandwidth.  We offer our on-net services to
customers located in buildings that are physically connected to our network.  We provide on-net
Internet access to net-centric and corporate  customers. Our net centric customers include certain
bandwidth-intensive users such as universities, other Internet  service providers,  telephone  companies,
cable  television companies and commercial content providers. These customers  generally  receive service
in colocation facilities and in our data centers. Our corporate customers  are located in  multi-tenant
office buildings and typically include law firms, financial services firms,  advertising and marketing firms
and other professional services businesses.

Our off-net services are sold to businesses that are  connected to our  network primarily by means
of ‘‘last mile’’ access service lines obtained from  other carriers, primarily in the  form of point-to-point
TDM, POS, SDH  and/or Carrier Ethernet circuits. Our non-core services, which consist primarily of

24

legacy services of companies whose assets or businesses we  have acquired, primarily include dial-up
Internet access services and voice services (only  provided in  Toronto, Canada). We  do  not  actively
market these non-core services and expect the  service revenue associated with them to continue  to
decline.

Our network is comprised of in-building  riser facilities, metropolitan optical fiber networks,

metropolitan  traffic aggregation points and inter-city transport facilities.  Our network  is physically
connected entirely through our facilities  to 1,579 buildings in which we provide our on-net services,
including 1,116 multi-tenant office buildings.  We also  provide on-net services in  carrier-neutral
colocation facilities, Cogent controlled  data centers  and  single-tenant office buildings.  Because of our
integrated network architecture, we are not dependent on  local  telephone companies  to  serve our
on-net customers. We emphasize the  sale of  our on-net  services because we believe we have a
competitive advantage in providing these  services and these services  generate  gross profit margins that
are greater than the gross profit margins on  our  off-net and non-core services.

We  also provide Internet connectivity to customers that  are not located in buildings directly
connected to our network. We serve  these  off-net customers using other  carriers’  facilities  to  provide
the ‘‘last mile’’ (local loop) portion of  the link  from our customers’ premises to our network. We also
provide certain non-core services which  are  legacy services which we acquired and continue  to  support
but do not actively sell.

We  believe our key growth opportunity is  provided by our high-capacity network,  which provides  us

with the ability to  add a significant number  of customers to our  network with minimal direct
incremental costs. Our focus is to add  customers to our  network in a way that maximizes its use and  at
the same time provides us with a profitable  customer mix. We  are  responding  to  this  opportunity by
increasing our sales and marketing efforts  including increasing our number of sales representatives. In
addition, we may add customers to our network through  strategic acquisitions.

We  are expanding our network to locations that  we believe  can  be  economically integrated and

represent significant concentrations of Internet traffic.  One  of  our keys  to developing a profitable
business will be to carefully match the cost of extending our  network to reach new  customers with the
revenue expected to be generated by  those customers.

We  believe two of the most important trends  in our industry are  the continued long-term growth in

Internet traffic and a decline in Internet  access prices within carrier  neutral data centers. As Internet
traffic continues to grow and prices per  unit of traffic continue  to  decline,  we believe  our  ability  to  load
our  network and gain market share from  less efficient network operators  will continue to expand.
However, continued erosion in Internet  access prices  will likely  have a negative impact on the rate at
which  we can increase our revenues and our  profitability. Our revenue  may also be negatively affected
if we are unable to grow our Internet  traffic or  if  the rate of growth  of Internet traffic  does not offset
the expected decline in per unit pricing. We  do not know if Internet traffic will increase or  decrease, or
the rate at which it will grow or decrease.  Changes in Internet traffic  will  be  a function of the  number
of users, the applications for which the Internet  is used, the pricing of Internet services, and  other
factors.

The growth in Internet traffic has a more significant  impact on our net  centric customers who
represent the majority of the traffic on  our  network and who tend to consume the majority  of  their
allocated bandwidth on their connections. Net  centric  customers tend to purchase their service on a
price per megabit basis. Our corporate customers tend to utilize a small portion of their allocated
bandwidth on their connections and  tend  to purchase their service on  a per connection basis.

Due to our strategic acquisitions of network assets  and equipment, we believe we are well

positioned to grow our revenue base. We  continue to purchase and deploy  network equipment to parts
of our network to maximize the utilization of our assets and to expand our network. Our future  capital

25

expenditures will be based primarily on  the expansion of our network,  the addition of on-net buildings
and the concentration and growth of  our  customer base. We plan  to  continue to expand our network
and to increase the number of on-net buildings we  serve. Many factors  can  affect our ability to add
buildings to our network. These factors  include the  willingness of building owners  to  grant us access
rights, the availability of optical fiber networks  to  serve those  buildings,  and equipment  availability.

Service Revenue. Our service revenue increased 11.7% from $235.8 million for  the year  ended

December 31, 2009 to $263.4 million for the year  ended December 31, 2010. The impact of  exchange
rates negatively impacted the increase  in revenues by approximately $1.2 million. All foreign currency
comparisons herein reflect results for the  year ended December 31, 2010 translated at  the average
foreign currency exchange rates for the year  ended December 31, 2009.  For the  years  ended
December 31, 2009 and 2010, on-net, off-net and non-core revenues  represented 79.9%, 18.4% and
1.7% and 77.8%, 21.0% and 1.2% of  our net service  revenues,  respectively.

Revenues from our corporate and net  centric customers represented 47.3%  and 52.7%  of our
service revenue, respectively, for the year  ended December 31, 2009, and represented 49.4% and 50.6%
of our service revenue, respectively, for the year ended  December 31,  2010. Revenues from  corporate
customers increased 16.5% from $111.6 million for  the year  ended  December 31, 2009 to $130.1  million
for the year ended December 31, 2010.  Revenues  from our net-centric customers increased 7.4% from
$124.2 million for the year ended December  31, 2009 to $133.3 million for the year ended
December 31, 2010. The difference in  the increase percentages  in net centric revenues  as compared  to

26

the increase in corporate revenues is  primarily attributed  to  a decline in the  average revenue  per  net
centric customer connection from discounting  and from  the impact  of exchange rates  (almost  all  of our
European revenues are from net centric  customers).

Our on-net revenues increased 8.8% from $188.5 million for the year ended  December 31, 2009 to

$205.0 million for the year ended December 31, 2010.  Our on-net revenues  increased  as we  increased
the number of our on-net customer connections  by 21.4%  from approximately 17,200 at December  31,
2009 to approximately 20,900 at December  31, 2010. On-net  customer connections increased at a
greater rate than on-net revenues due  to  a  decline  in the average revenue  per  on-net customer
connection—primarily from our net centric customers. This decline  is partly attributed to a shift  in the
customer connection mix and due to  volume and term  based pricing discounts. Additionally,  on-net
customers who cancel their service from  our installed base of customers, in general, have greater
average revenue per connection than  new  customers.  These trends  and the impact of foreign exchange
rates resulted in a reduction to our average revenue  per  on-net connection.

Our off-net revenues increased 27.6%  from $43.3 million for the year  ended December  31, 2009 to
$55.3 million for the year ended December 31, 2010.  Our  off-net customer  connections increased 9.0%
from approximately 3,200 at December  31, 2009 to approximately 3,500 at December 31, 2010.  Off-net
revenues increased at a greater rate than off-net customer connections due to an  increase in the
average revenue per off-net customer connection. Off-net  customers who cancel their service, in
general, have an average revenue per  connection and per connection bandwidth speed that is less than
the average revenue per connection for  new off-net  customers who generally purchase higher-
bandwidth connections.

Our non-core revenues decreased 22.0%  from $4.0 million for the year ended  December 31,  2009

to $3.1 million for the year ended December 31, 2010. The number  of  our  non-core customer
connections decreased 29.9% from approximately 900 at  December 31,  2009 to approximately 650  at
December 31, 2010. We do not actively market these  acquired non-core  services and  expect that the
service revenue associated with them  will  continue  to  decline.

Network Operations Expenses. Network operations expenses include costs associated with service
delivery, network management, and customer support. This includes the costs of personnel  and related
operating expenses associated with these activities, network  facilities costs, fiber  and equipment
maintenance fees, leased circuit costs,  and access  and  facilities  fees  paid to building owners. Our
network operations expenses, excluding  equity-based compensation expense, increased 15.6% from
$102.6 million for the year ended December 31, 2009  to  $118.7 million for the year ended
December 31, 2010. The impact of exchange rates resulted  in a  reduction of network  operations
expenses for the year ended December 31,  2010 of approximately $0.9 million. The increase in network
operations expenses is primarily attributable to an increase in costs  related to our network  and facilities
expansion activities including personnel  and related operating  expenses and an increase  in our off-net
revenues. When we provide off-net revenues  we also assume the cost of the associated tail-circuits.

Selling, General, and Administrative Expenses  (‘‘SG&A’’). Our SG&A expenses, excluding equity-
based compensation expense, decreased  3.9% from $68.5  million for the year ended  December 31, 2009
to $65.8 million for the year ended December 31, 2010. SG&A  expenses decreased primarily from a
reduction in SG&A personnel costs,  a reduction in bad debt  expense  and a reduction in certain
non-income taxes related to our European  operations.  The  impact of exchange  rates resulted in a
reduction of approximately $0.5 million  in SG&A expenses.

Equity-based Compensation Expense. Equity-based compensation expense is related to restricted
stock and stock options. Our equity-based compensation expense decreased 22.9% from $8.6 million  for
the year ended December 31, 2009 to  $6.6 million for the year ended December 31, 2010. The decrease
is primarily due to the completion of the  service  period in April 2009  of  certain restricted stock  grants

27

made to our employees in April 2007 partly offset  by  the impact  of grants  of  restricted shares  to
certain of our employees in the second  quarter of  2010. In the second quarter of 2010,  we granted
approximately 0.9 million restricted shares to certain of our employees that will vest over a  three year
period. These restricted shares were valued at approximately $9.6 million and  will  be  recognized as
equity-based compensation expense on a  straight line basis  over the three year service period. In April
2010, we also granted an additional 0.2  million  restricted shares that are subject  to  certain performance
conditions based upon our operating metrics for 2010,  2011 and  2012. We recorded approximately
$0.2 million of equity-based compensation expense  related to the  performance conditions  for 2010 in
the fourth quarter of 2010 since it was considered probable that  the performance conditions would  be
met. These restricted shares were valued  at approximately  $0.5 million and will  be  recognized as equity-
based compensation expense on a straight  line basis over the  requisite service  period through  April 15,
2011. The total equity based compensation expense for  the performance  shares related to 2011 (if  the
conditions are met) is approximately  $0.9 million and will be recognized  over the requisite  service
period of approximately one year.

Asset Impairment.

In 2010, we recorded an impairment charge of  $0.6 million  related  to  certain

property and equipment that were no longer in  use. There were  no such  charges in 2009.

Depreciation and Amortization Expenses. Our depreciation and amortization expense decreased
5.7% from $59.9 million for the year ended December  31, 2009 to $56.5  million  for the  year  ended
December 31, 2010. The decrease is primarily due to the decline in depreciation  expense from fully
depreciated fixed assets and an adjustment to our  asset retirement  obligations, discussed below, more
than offsetting depreciation expense  associated with the increase related to newly deployed  fixed  assets.
The impact of exchange rates resulted in  a reduction  of  approximately  $0.2 million in depreciation and
amortization expenses.

In the first quarter of 2010, we determined  that our  estimates of  restoration costs  for our leased

facility asset retirement obligations were  too high based on current costs to restore and  changes in the
expected timing of the payment of those costs due to the extensions of  lease terms. As a result, in the
first quarter of 2010, we revised our  estimates  of the cash flows  that we  believed  will be required to
settle our leased facility asset retirement  obligations at the end of the respective lease  terms, which
resulted in a reduction to our asset retirement obligation liability. These revisions  in the estimated
amount and timing of cash flows for  asset retirement obligations reduced  our asset retirement
obligation liability by $0.9 million with  an offsetting reduction  to  depreciation  and amortization of
$0.7 million and selling, general and  administrative  expenses of  $0.2 million.

Income  Tax  Provision  (Benefit). The income tax benefit was $1.2 million for the year  ended

December 31, 2009 and $1.2 million  for the year ended December 31, 2010. The net income tax benefit
for the year ended December 31, 2009  includes income taxes for the United States of approximately
$0.3 million for state income taxes (including approximately $0.1 million related to penalties and
interest on an uncertain tax position)  offset by a  tax  benefit of $1.5 million from  the partial reduction
of a valuation allowance on deferred  tax  assets related to our Canadian operations. The net income tax
benefit for the year ended December  31,  2010 includes income taxes for the  United States of
approximately $0.7 million for state income taxes  (including approximately $0.3 million related  to
uncertain tax positions), $0.1 million  of income tax provision related to our European operations offset
by a tax benefit of $1.5 million from the  reduction of the remaining valuation allowance on net
deferred tax assets related to our Canadian operations  and $0.6 million related to a refund of federal
alternative minimum taxes.

Buildings On-net. As of December 31, 2009 and 2010 we had a total  of  1,451 and  1,579 on-net

buildings connected to our network, respectively.

Service Revenue. Our service revenue increased 9.4% from $215.5 million for  the year  ended
December 31, 2008 to $235.8 million for the year  ended December 31, 2009. The impact of  exchange
rates negatively impacted the increase  in revenues by approximately $3.9 million. All foreign currency
comparisons herein reflect results for the  year ended December 31, 2009 translated at  the average
foreign currency exchange rates for the year  ended December 31, 2008.  For the  years  ended
December 31, 2008 and 2009, on-net, off-net and non-core revenues  represented 81.7%, 16.1% and
2.2% and 79.9%, 18.4% and 1.7% of  our net service  revenues,  respectively.

Revenues from our corporate and net  centric customers represented 44.7%  and 55.3%  of our
service revenue, respectively, for the year  ended December 31, 2008 and represented 47.3% and 52.7%
of our service revenue, respectively, for the year ended  December 31,  2009. Revenues from  corporate
customers increased 15.9% from $96.3 million for  the year  ended  December 31, 2008 to $111.6  million
for the year ended December 31, 2009.  Revenues  from our net-centric customers increased 4.2% from
$119.2 million for the year ended December  31, 2008 to $124.2 million for the year ended
December 31, 2009. The difference in  the increase percentages  in net centric revenues  as compared  to
the increase in corporate revenues is  primarily attributed  to  a decline in the  average revenue  per  net
centric  customer connection from discounting and from  the impact  of exchange rates  (almost  all  of our
European revenues are from net centric customers).  In June 2008,  we  introduced  additional volume
and  term based discounts to certain of our net  centric customers in  an effort to continue  to  gain
market share and to continue to grow our  revenues.

29

Our on-net revenues increased 7.1% from $176.0 million for the year ended  December 31, 2008 to

$188.5 million for the year ended December 31, 2009.  Our on-net revenues  increased  as we  increased
the number of our on-net customer connections  by 21.5%  from approximately 14,100 at December  31,
2008 to approximately 17,200 at December  31, 2009. On-net  customer connections increased at a
greater rate than on-net revenues due  to  a  decline  in the average revenue  per  on-net customer
connection—primarily from our net centric customers. This decline  is partly attributed to a shift  in the
customer connection mix and due to  volume and term  based pricing discounts. Due to the increase in
the size of our sales force, we are now able  to  focus not only  on  customers who  purchase
high-bandwidth connections, as we have  done  historically, but also on  customers who purchase lower-
bandwidth connections. We expect to continue to focus our sales efforts on a broad mix of customers.
Additionally, on-net customers who cancel their service from our installed base of customers, in
general, have greater average revenue per connection than new  customers.  These trends and  the impact
of foreign exchange rates resulted in  a reduction to our  average revenue per on-net connection.

Our off-net revenues increased 25.3%  from $34.6 million for the year  ended December  31, 2008 to
$43.3 million for the year ended December 31, 2009.  Our  off-net customer  connections increased 6.4%
from approximately 3,000 at December  31, 2008 to approximately 3,200 at December 31, 2009.  Off-net
revenues increased at a greater rate than off-net customer connections due to an  increase in the
average revenue per off-net customer connection. Off-net  customers who cancel their service, in
general, have an average revenue per  connection and per connection bandwidth speed that is less than
the average revenue per connection for  new off-net  customers who generally purchase higher-
bandwidth connections.

Our non-core revenues decreased 17.6%  from $4.9 million for the year ended  December 31,  2008

to $4.0 million for the year ended December 31, 2009. The number  of  our  non-core customer
connections increased 51.1% from approximately  600 at December 31, 2008 to approximately 900  at
December 31, 2009 primarily due to the  May 2009 acquisition of approximately 700  non-core customer
connections. We do not actively market  these acquired  non-core services and expect  that  the service
revenue associated with them will continue to decline.

Network Operations Expenses. Our network operations expenses, excluding equity-based

compensation expense, increased 10.7%  from $92.7 million for the year ended December 31,  2008 to
$102.6 million for the year ended December 31, 2009.  The impact  of exchange rates  resulted in  a
reduction of network operations expenses for  the year ended December 31, 2009  of approximately
$1.4 million. The increase in network  operations  expenses is primarily  attributable  to  an increase in
costs related to our network and facilities expansion activities and an increase in  our off-net  revenues.
When we provide off-net revenues we also assume the cost  of the associated  tail-circuits.

Selling, General, and Administrative Expenses  (‘‘SG&A’’). Our SG&A expenses, excluding equity-

based compensation expense, increased  8.8% from $62.9  million for the  year ended December  31, 2008
to $68.5 million for the year ended December 31, 2009. SG&A  expenses increased primarily from the
increase in salaries and related costs required  to  support our expanding  sales  and marketing efforts.
The impact of exchange rates resulted in  a reduction  of  approximately  $1.2 million in SG&A expenses.

Equity-based Compensation Expense. Equity-based compensation expense is related to restricted

stock and stock options. Our total equity-based  compensation  expense decreased 51.9% from
$17.9 million for the year ended December 31, 2008  to  $8.6 million for the year ended December 31,
2009. Equity-based compensation expense  decreased primarily due  to  the completion of the  service
period in April 2009 of certain restricted stock  grants made  in April  2007 and  $1.2 million of equity-
based compensation expense related to share grants made to our board of directors  in January 2008.
There were no such grants to our board  of directors in  2009.

30

Depreciation and Amortization Expenses. Our depreciation and amortization expense decreased
4.3% from $62.6 million for the year ended December  31, 2008 to $59.9  million  for the  year  ended
December 31, 2009. The decrease is primarily due to the decline in depreciation  expense from fully
depreciated fixed assets more than offsetting depreciation  expense associated  with the increase  in
deployed fixed assets. The impact of  exchange  rates  resulted in a reduction of approximately
$0.6 million in depreciation and amortization expenses.

Asset Impairment.

In 2008, we recorded an impairment charge of  $1.6 million  related  to  an  IRU
asset under a capital lease. The IRU asset  was no  longer in  use and we  have obtained alternative dark
fiber that serves the related facilities and  customers. There was no such charge  in 2009.

Gains on Purchases of Convertible Senior Notes.

In June 2007, we issued our 1.00% Convertible

Senior Notes (the ‘‘Notes’’) due June 15,  2027,  for an aggregate principal amount of $200.0 million.  In
2008, we purchased an aggregate of $108.0 million of face value  of the Notes for $48.6 million in cash
in a series of transactions. These transactions  resulted in gains totaling $23.1 million for the year ended
December 31, 2008. There were no purchases of Notes in the  year ended December  31, 2009.

Income Tax Provision (Benefit). The income tax provision was $1.5 million for  the year ended

December 31, 2008 and an income tax  benefit  of  $1.2  million was recorded for the year ended
December 31, 2009. In the year ended  December 31,  2008, primarily due to the gains on the purchases
of our Notes, we became subject to the  alternative minimum tax in the United  States. Under  the
alternative minimum tax system, the ability  to  offset taxable income with the utilization of net operating
loss carryforwards is limited. The tax  provision for the year ended  December 31, 2008 includes income
taxes for the United States of approximately $0.6  million  for federal alternative minimum tax and
approximately $0.9 million for state income taxes  (including approximately $0.5 million related  to  an
uncertain tax position). The net income tax benefit for  the year ended December 31, 2009 includes
income taxes for the United States of  approximately $0.3  million for state income taxes (including
approximately $0.1 million related to  penalties and interest on  an uncertain tax  position) offset by a tax
benefit of $1.5 million from the partial  reduction of a valuation allowance on deferred tax assets
related to our Canadian operations.

Buildings On-net. As of December 31, 2008 and 2009 we had a total  of  1,326 and  1,451 on-net

buildings connected to our network, respectively.

Liquidity and Capital Resources

In assessing our liquidity, management  reviews  and  analyzes our current cash  balances,  short-term

investments, accounts receivable, accounts payable, accrued liabilities, capital expenditure and operating
expense commitments, and required capital  lease, interest and debt payments and other obligations.

Net Cash Provided By Operating Activities. Our primary sources of operating cash are receipts
from our customers who are billed on a  monthly  basis for our  services. Our  primary  uses of  operating
cash are payments made to our vendors, employees  and interest payments made  to  our capital  lease
vendors and our note holders. Net cash  provided by operating activities was $54.3  million for the year
ended December 31, 2008 compared to net cash provided by operating activities  of $56.9 million for
the year ended December 31, 2009. The increase in  cash provided by operating activities is due to an
increase in our operating profit partly offset  by  changes in operating assets and liabilities. Net  cash
provided by operating activities was $56.9  million for  the year  ended December 31, 2009 compared to
net cash  provided by operating activities  of  $71.5 million for the year ended December 31,  2010. The
increase in cash provided by operating  activities is  due  to  an increase in  our  operating profit  and an
increase in changes in operating assets  and liabilities.

Net Cash Used In Investing Activities. Net cash used in investing activities was $32.5 million for

the year ended December 31, 2008, $49.4  million for the year ended December 31,  2009 and
$52.2 million for the year ended December 31, 2010.  Our  primary use of investing cash during 2008
was $33.5 million for the purchases of  property  and  equipment.  Our primary sources of  investing cash
in 2008 were $0.7 million from the proceeds  of the maturities  of short-term investments  and
$0.2 million from the proceeds of the  sales  of  assets. Our primary use  of  investing cash during 2009  was
$49.5 million for the purchases of property  and equipment. Our primary sources of investing cash in
2009 was $0.3 million from the proceeds of the sales of assets. Our primary use of investing cash  during
2010 was $52.8 million for the purchases of property and  equipment. Our  primary  sources  of investing
cash in 2010 was $0.5 million from the  proceeds of the sales of assets.  The increases in  purchases of
property and equipment from the year ended  December  31,  2008 to the  year ended December  31, 2009
and from the year ended December  31, 2009  to  the year ended December 31, 2010 were  primarily due
to our increase in our network expansion activities  including geographic expansion  and adding  more
buildings to our network.

Net Cash Used In Financing Activities. Financing activities used cash of $125.6 million for  the year

ended December 31, 2008, $23.5 million  for the  year ended December 31, 2009 and $18.9  million for
the year ended December 31, 2010. Our primary use of financing cash for the year ended
December 31, 2008 was $59.3 million  for the  purchase  of shares of  our common stock, $48.6 million for
repurchases of our 1.00% convertible senior notes  and $18.0 million of principal  payments under our
capital lease obligations. Our primary  use  of  financing cash for  the year  ended December 31, 2009  was
$23.2 million of principal payments under our capital  lease obligations and $0.7 million for the
purchases of shares of our common stock. Our primary source of financing cash for the year ended
December 31, 2009 was $0.3 million  of  proceeds from the exercises of stock options. Our primary use
of financing cash for the year ended December 31,  2010 was $19.1 million of principal  payments under
our  capital lease obligations. Our primary  source of financing cash for the year ended  December 31,
2010 was $0.3 million of proceeds from  the exercises of stock options. The increase  in principal
payments under our capital lease obligations  from the year ended December 31, 2008 to the years
ended December 31, 2009 and 2010 was  primarily due  to  the increase in  our  network expansion
activities.

Indebtedness

Our total indebtedness, net of discount, at  December  31, 2010 was $182.9 million  and our total
cash and cash equivalents were $56.3 million.  Our total indebtedness at December  31, 2010 includes
$111.7 million of capital lease obligations  for dark  fiber primarily  under  15–25 year IRUs.

Convertible Senior Notes

In June 2007, we issued our 1.00% convertible  senior  notes (the ‘‘Convertible Notes’’) due
June 15, 2027, for an aggregate principal amount of $200.0 million in  a private  offering for resale to

32

qualified institutional buyers pursuant  to  SEC Rule  144A. The Convertible Notes are unsecured  and
bear interest at 1.00% per annum. The  Convertible Notes will rank equally with any  future senior debt
and senior to any future subordinated  debt  and will be effectively subordinated  to  all  of our  subsidiary’s
existing and future liabilities and to any  secured debt that  we may issue to the  extent of the value of
the collateral. Interest is payable in cash semiannually  in arrears on June 15  and December 15,  of  each
year, beginning on December 15, 2007. We received proceeds of approximately $195.1 million after
deducting the original issue discount  of 2.25% and  issuance  costs.

In 2008, we purchased $108.0 million  of face value of our Convertible Notes  for $48.6 million  in

cash in a series of transactions. These transactions resulted  in a  gain  of  $23.1 million for the year
ended December 31, 2008. After these transactions there  is $92.0  million of  face value of our
Convertible Notes outstanding. We may  purchase  additional  Convertible Notes.

The Convertible Notes are convertible into shares of our common stock at an initial conversion
price of $49.18 per share, or 20.3355 shares  for each  $1,000 principal amount of Convertible Notes,
subject to adjustment for certain events as set forth  in the indenture. Upon  conversion  of the
Convertible Notes, we will have the right  to  deliver shares of our  common  stock,  cash or  a combination
of cash and shares of our common stock.  The Convertible  Notes are convertible (i) during any fiscal
quarter after the fiscal quarter ending September 30,  2007, if the closing sale price of  our common
stock for 20 or more trading days in  a  period of 30  consecutive trading  days ending on the last trading
day of the immediately preceding fiscal  quarter exceeds 130%  of the conversion price in effect on  the
last trading day of the immediately preceding fiscal quarter, or (ii) specified corporate transactions
occur, or (iii) the trading price of the Convertible Notes falls  below a certain threshold,  or (iv) if we
call the Convertible Notes for redemption,  or (v) on or after  April 15, 2027, until maturity. In addition,
following specified corporate transactions, we will  increase the  conversion  rate for holders who elect to
convert Convertible Notes in connection with such corporate transactions, provided  that  in no  event
may the shares issued upon conversion, as a  result of adjustment or otherwise, result  in the issuance of
more than 35.5872 common shares per $1,000 principal amount. The  Convertible Notes include an
‘‘Irrevocable Election of Settlement’’  whereby we may choose,  in our sole discretion, and without the
consent of the holders of the Convertible  Notes, to waive  our right to settle the conversion feature  in
either cash or stock or in any combination, at our option.

The Convertible Notes may be redeemed  by  us  at any time after  June 20,  2014 at  a redemption
price of 100% of the principal amount  plus  accrued interest. Holders of the Convertible Notes have the
right to require us to repurchase for  cash all or  some of  their Convertible Notes on  June  15, 2014, 2017
and 2022 and upon the occurrence of  certain designated events  at  a  redemption price of 100% of the
principal amount plus accrued interest.

Revolving Line of Credit

In October 2009, we entered into a $20.0 million revolving line of credit  facility with a  commercial

bank. The credit facility had a floating  interest rate of one month  LIBOR  plus 2.5% per annum,
subject to a minimum interest rate of  3.0% and  had  a commitment fee  of  0.3% per annum. There  were
no borrowings under the revolving facility  and we  were  in compliance  with its covenants. The  facility
expired on October 14, 2010.

Senior Secured Notes

In January 2011, we issued our 8.375% Senior Secured  Notes (the ‘‘Senior Notes’’) due

February 15, 2018, for an aggregate principal amount of $175.0 million in  a private  offering for resale
to qualified institutional buyers pursuant  to SEC  Rule 144A.  The Senior Notes are  secured and bear
interest at 8.375% per annum. Interest is  payable in cash  semiannually  in arrears  on February 15 and
August 15, of each year, beginning on August 15,  2011. We received net  proceeds of  approximately

33

$170.5 million after deducting $4.5 million  of issuance costs. We  intend to use the net proceeds from
the Senior Notes for general corporate  purposes and/or  repurchases  of our common stock or  our
Convertible Notes or a special dividend  to our stockholders.

The Senior Notes are fully guaranteed on a senior secured  basis, jointly and severally, by each of

our  existing domestic and future material domestic subsidiaries, subject  to  certain exceptions and
permitted liens. Under certain circumstances, subsidiaries may be released from these guarantees
without the consent of the holders of  the  Senior Notes. The Senior Notes and the guarantees are
secured by (i) first priority liens on substantially all of our and  our guarantors’ assets, (ii) all of the
equity interests in any of our domestic  subsidiaries and (iii) 65% of the equity interests of our first-tier
foreign subsidiaries held by us and our guarantors. The Senior Notes and the guarantees represent our
and the guarantors’ senior secured obligations and effectively rank equally and ratably with all of our
and the guarantors’ existing and future  first lien obligations, to the extent of the  value of  the collateral
securing such indebtedness, subject to  permitted  liens; are structurally subordinated  to  any existing and
future indebtedness and liabilities of  non-guarantor  subsidiaries and  rank  equally  in right of  payment
with all  of our and the guarantors’ existing and future senior indebtedness.

The Senior Notes may be redeemed, in whole  or in part, at any time prior to February 15, 2015 at
a price equal to 100% of the principal  amount  plus a ‘‘make-whole’’ premium, plus  accrued and  unpaid
interest, if any, to the date of redemption.  The  Senior Notes  are redeemable, in whole or in part,  at
any time on or after February 15, 2015  at the applicable redemption prices  specified under  the
indenture governing the Senior Notes plus accrued  and unpaid interest, if any,  to  the date  of
redemption. In addition, we may redeem  up to 35%  of  the Senior Notes before February 15, 2014  with
the net cash proceeds from certain equity  offerings.  If we experience  specific kinds of changes of
control, we must offer to repurchase  all of the Senior Notes at a purchase price of  101% of their
principal amount, plus accrued and unpaid interest, if any, to the repurchase date.

The indenture governing the Senior Notes, among other things, limits our ability and our

guarantors’ ability to incur indebtedness; to pay dividends  or make other  distributions; to make certain
investments and other restricted payments; to create liens; consolidate,  merge, sell or otherwise dispose
of all or substantially all of our assets;  to  incur restrictions on  the ability of a subsidiary to pay
dividends or make other payments; and to enter into certain  transactions  with  our affiliates.

Common Stock Buyback Program

In June 2007 we used approximately  $50.1 million of the net proceeds from our issuance of our

Convertible Notes to repurchase approximately 1.8 million shares of our common stock.  In August
2007, our board of directors approved  a  $50.0 million common stock buyback  program. In June 2008,
our  board of directors approved an additional $50.0 million of purchases  of our common  stock  under
the buyback program to occur prior to  December 31,  2009. In the years ended  December 31, 2007,
2008 and 2009, we purchased approximately 2.2 million, 4.4  million and 0.1  million shares of our
common stock, respectively, for approximately $59.9 million,  $59.3 million and  $0.7 million, respectively.
All purchased common shares were subsequently  retired. There  were no purchases of common stock  in
the year ended December 31, 2010.

(1) The Convertible Notes are assumed  to  be  outstanding until June 15,  2014 which  is the earliest  put
date  and these amounts include interest and principal payment  obligations on  the Convertible
Notes.

(2) The $175.0 million Senior Notes  were issued  in January  2011 and these amounts  include interest

and principal payment obligations through  the maturity date of February 15, 2018.

(3) These amounts include operating lease, maintenance,  building access and  tenant license agreement

obligations.

(4) As of December 31, 2010, we had committed to additional dark fiber IRU lease  agreements

totaling approximately $62.6 million in future payments  for  fiber lease  and  maintenance services.
These amounts are included in unconditional  purchase obligations and  are to be paid  in periods of
up to 20 years beginning once the related fiber is  accepted.

Capital Lease Obligations. The capital lease obligations above were incurred in connection with

IRUs for inter-city and intra-city dark fiber  underlying  substantial portions of our network.  These
capital leases are presented on our balance sheet at the net present value of the  future minimum lease
payments, or $111.7 million at December  31, 2010. These  leases generally have  initial terms  of  15 to
20 years.

Letters of Credit. We are also party to letters of credit  totaling  $0.5 million at December 31, 2010.
These obligations are fully secured by our restricted investments, and as a result, are excluded  from the
contractual cash obligations above.

Future Capital Requirements

We believe that our cash on hand, cash received from the proceeds  of our  Senior Notes  and cash

generated from our operating activities will be adequate to meet our working capital, capital
expenditure, debt service, and other  cash requirements if we execute our business plan.

Any future acquisitions or other significant unplanned costs  or  cash requirements may require  that

we raise additional funds through the  issuance of debt or equity. We cannot assure you that such
financing will be available on terms acceptable  to  us or our stockholders, or at all. Insufficient funds
may require us to delay or scale back the number of buildings  and markets that we add to our network,
reduce our planned increase in our sales and marketing efforts,  or  require us to otherwise alter our
business plan or take other actions that could  have a  material  adverse effect on our  business,  results of

35

operations and financial condition. If  issuing equity securities raises additional funds, substantial
dilution to existing stockholders may result.

Off-Balance Sheet Arrangements

We  do not have relationships with unconsolidated entities or financial partnerships,  such as  entities

often referred to as structured finance  or special purpose entities, which would have  been established
for the purpose of facilitating off-balance sheet arrangements  or other  contractually narrow or  limited
purposes. In addition, we do not engage  in trading activities  involving  non-exchange traded contracts.
As such, we are not materially exposed to any financing, liquidity, market or credit risk that could arise
if we had engaged in these relationships.

Income taxes

Due to the uncertainty surrounding the  realization of our net  deferred tax asset, we have recorded
a valuation allowance for a substantial majority of our net deferred tax asset. As of December 31, 2010,
we have combined net operating loss carry-forwards  of  approximately $1.1 billion. This amount includes
federal and state net operating loss carry-forwards in  the United  States of  approximately $376.0 million,
net operating loss carry-forwards related to our Canadian  operations of  approximately  $6.2 million, net
operating loss carry-forwards related  to  our operations in Mexico of approximately $0.8 million and net
operating loss carry-forwards related  to  our European operations  of approximately $686.6 million.
Section 382 of the Internal Revenue Code in the United States  limits the utilization of  net operating
losses when ownership changes, as defined by that section, occur.  We have performed an analysis of
our  Section 382 ownership changes and have determined that the utilization of certain  of  our  net
operating loss carryforwards in the United States may be limited. The net  operating loss carryforwards
in the United States will expire, if unused, between 2022 and 2029. The net operating loss  carry-
forwards related to our Canadian operations expire if  unused, between 2015 and  2027. The net
operating loss carry-forwards related  to  our Mexican operations  expire if unused,  between 2019 and
2020. The net operating loss carry-forwards related to our European operations include $540.8 million
that do not expire and $145.8 million  that expire between 2011 and 2026.

Critical Accounting Policies and Significant Estimates

Our discussion and analysis of our financial condition and results of  operations are  based upon our

consolidated financial statements, which  have  been prepared in accordance  with accounting principles
generally accepted in the United States. The  preparation of  these financial statements requires us to
make estimates and judgments that affect  the reported amounts of assets,  liabilities, revenue and
expenses, and the related disclosure  of contingent  assets and  liabilities. We base our  estimates on
historical experience and on various  other  assumptions that are believed  to be reasonable under  the
circumstances, the results of which form the basis  for making judgments  about  the carrying values of
assets and liabilities that are not readily  apparent from  other sources. Actual results may  differ  from
these estimates under different assumptions  or conditions.

The accounting policies we believe to be most critical to understanding our financial results  and

condition or that require complex, significant  and  subjective management judgments are  discussed
below.

Revenue Recognition

We  recognize service revenue when the services are performed,  evidence of an arrangement  exists,
the fee is fixed and determinable and  collection is probable.  Service discounts  and incentives offered to
certain customers are recorded as a reduction  of revenue  when granted. Fees billed  in connection  with
customer installations are deferred and recognized ratably over the  longer of estimated customer life or

36

contract term. We determine the estimated customer life using  a historical analysis  of customer
retention and contract terms. If our estimated customer life and contract terms increase,  we will
recognize installation revenue over a longer period. We expense the direct  costs associated  with sales as
incurred.

Allowances for Sales Credits and Unfulfilled Customer Purchase Obligations

We  have established allowances to account for sales credits and unfulfilled  contractual  purchase

obligations.

(cid:127) Our allowance for sales credits is recorded as a reduction to our service revenue to provide  for
situations when customers are granted a service termination adjustment  for amounts billed  in
advance or a service level agreement credit or discount. This allowance  is determined by actual
credits granted during the period and an estimate  of  unprocessed credits.

(cid:127) Our allowance for unfulfilled contractual  customer purchase obligations  is designed  to  account
for the possible non-payment of amounts  under agreements that we have with certain of  our
customers that place minimum purchase obligations  on them. Although we vigorously  seek
payments due pursuant to these purchase obligations,  we have  historically collected only a small
portion of these billed obligations. In  order  to  allow for  this,  we reduce  our gross service
revenue by the amount that has been invoiced to these customers. We reduce  this allowance and
recognize the related service revenue only upon the  receipt of cash payments in respect of these
invoices. This allowance is determined by the amount of unfulfilled contractual purchase
obligations invoiced to our customers and with  respect to which  we are continuing to seek
payment.

Valuation Allowances for Doubtful Accounts Receivable and Deferred Tax Assets

We  have established allowances associated with  uncollectible  accounts receivable and our deferred

tax assets.

(cid:127) Our valuation allowance for uncollectible accounts  receivable is  designed to account for the

expense associated with accounts receivable that we  estimate will not be collected. We assess the
adequacy of this allowance by evaluating general factors,  such as  the length of time individual
receivables are past due, historical collection experience, and changes in  the credit-worthiness of
our  customers. We also assess the ability of specific customers  to  meet  their financial  obligations
to us and establish specific allowances based on  the amount we expect to collect from these
customers. If circumstances relating to specific  customers change  or  economic  conditions change
such that our past collections experience  and  assessment of the economic environment  are no
longer appropriate, our estimate of  the recoverability of our trade  receivables could be impacted.

(cid:127) Our valuation allowance for our net deferred tax  asset reflects the  uncertainty surrounding the
realization of our net operating loss carry-forwards  and our other deferred tax assets. To reflect
for the uncertainty of future taxable  income  we have  recorded a valuation allowance for  the
significant majority of our net deferred tax asset. At each balance sheet date, we assess  the
likelihood that we  will be able to realize  our  deferred tax assets.  We consider all available
positive and negative evidence in assessing the need for a valuation allowance. As of
December 31, 2008, we determined that a full  valuation  allowance  against our deferred tax
assets was necessary primarily due to the effect  of  historical operating losses.  At December  31,
2009, we concluded that it was more likely than  not  that  we would be able  to  realize certain of
our  Canadian deferred tax assets primarily as  a result  of  our  estimate of expected future taxable
income related to our Canadian operations. Accordingly, we reduced the  valuation allowance
recording an income tax benefit of $1.5 million in the  year ended December  31, 2009. At
December 31, 2010, we concluded that it was more likely than not that  we  would be able  to

37

realize the remainder of our Canadian deferred tax  assets. Accordingly, we reduced the
remaining valuation allowance related to our Canadian deferred tax  assets recording an  income
tax benefit of $1.5 million in the year ended December 31, 2010.  As of December 31, 2010, we
maintained a full valuation allowance against our  other  deferred tax assets  consisting primarily
of net operating loss carryforwards.

Equity-based Compensation

We  grant options for shares of our common stock to certain  of our  employees with  a strike  price

equal to the market value at the grant  date. We grant shares of restricted  stock  to  our  senior
management team and to certain other employees.  We determine the  fair value of grants of  restricted
stock by the closing trading price of our common  stock  on the  grant date.  We determine the  fair value
of grants of options for shares of common stock  by  the closing trading  price of our common stock on
the grant date using the Black-Scholes  method. Grants  of  shares  of  restricted stock and options for
common stock generally vest over periods  ranging from three to four-years. In April 2010,  we granted
0.2 million restricted shares that are subject to certain performance conditions. We record equity-based
compensation expense related to the  performance conditions when it  is considered probable that the
conditions will be met. Compensation  expense for all awards is  recognized  ratably over  the service
period.

The accounting for equity-based compensation expense  requires us to make additional  estimates

and judgments that affect our financial  statements. These estimates include the following.

Expected Dividend Yield—We have never  declared  or paid dividends and have no plans  to  do  so

in the foreseeable future.

Expected Volatility—We use the historical volatility for a period commensurate  with the expected

term.

Risk-Free Interest Rate—We use the zero coupon U.S. Treasury rate during the quarter having a

term that most closely resembles the expected term of the option.

Expected Term of the Option—We estimate the expected life of the  option term  by  analyzing

historical stock option exercises and other  relevant  data.

Forfeiture Rates—We estimate the forfeiture rate  based on historical data with further
consideration given to the class of employees to whom the options or shares were granted.

Other Accounting Policies

We  record assets and liabilities under capital  leases at  the lesser  of the present value of the
aggregate future minimum lease payments  or the fair value of the assets  under lease. We establish the
number of renewal option periods used  in determining  the lease term, if any, based  upon our
assessment at the inception of the lease  of the  number of option periods that are reasonably  assured.
We  estimate the fair value of leased assets  using  market  data for similar assets.

We  capitalize the direct costs incurred  prior to an  asset being ready for service. These costs include
costs under the related construction  contract and the compensation costs of employees  directly involved
with construction activities. Our capitalization of these costs  is based upon estimates  of time  for our
employees involved in construction activities.

We  estimate our litigation accruals based upon our estimate  of the expected outcome after

consultation with legal counsel.

We  estimate our accruals for disputed leased  circuit obligations based upon the nature and age of

the dispute. Our network costs are impacted by the timing  and  amounts of  disputed circuit costs.  We

38

generally record these disputed amounts  when billed by the vendor and reverse these  amounts when
the vendor credit has been received or  the dispute  has otherwise been resolved.

We  estimate the useful lives of our property and equipment based upon historical usage with
consideration given to technological  changes and  trends in  the industry that could impact the asset
utilization. We establish the number  of  renewal option periods used in determining  the lease term, if
any, for amortizing leasehold improvements  based upon  our assessment at  the inception of the  lease of
the number of option periods that are  reasonably assured.

Recent  Accounting Pronouncements

Recent Accounting Pronouncements—to be Adopted

In September 2009, the FASB issued  Accounting Standards Update  (‘‘ASU’’)  2009-13, Multiple
Element Arrangements. ASU 2009-13 addresses the determination of when the individual  deliverables
included in a multiple arrangement may  be treated as separate units  of accounting. ASU 2009-13 also
modifies the manner in which the transaction consideration  is allocated across  separately identified
deliverables and establishes definitions  for determining fair value  of elements in an arrangement.  This
standard must be adopted by us no later  than January 1, 2011. The adoption of this standard  update is
not expected to have a material impact  on  our consolidated  financial statements.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES  ABOUT MARKET  RISK

We  are exposed to certain market risks. These risks, which  include interest  rate risk and foreign

currency exchange risk, arise in the normal course of business rather than from  trading activities.

Interest Rate Risk

Our cash  flow exposure due to changes  in interest rates related  to  our debt is limited as our
Convertible Notes and Senior Notes have  fixed interest rates. The fair value  of  our  Convertible Notes
may increase or decrease for various reasons, including fluctuations in the market price of  our common
stock, fluctuations in market interest  rates  and fluctuations in general economic  conditions. Based upon
the quoted market price at December  31,  2010, the fair  value of our Convertible Notes was
approximately $78.4 million.

Our interest income is sensitive to changes  in the general level of interest rates. However,  based
upon the nature and current level of our investments, which are  primarily  cash and cash equivalents, we
believe that there is no material interest  rate  exposure related to our investments.

Senior Secured Notes

In January 2011, we issued our 8.375% Senior Notes due February  15, 2018, for an aggregate
principal amount of $175.0 million in  a  private offering for  resale to qualified institutional buyers
pursuant to SEC Rule 144A. The Senior Notes are  secured and  bear interest at a fixed rate of 8.375%
per  annum. Interest is payable in cash  semiannually in arrears on  February 15  and August 15, of each
year, beginning on August 15, 2011. We  received  net proceeds  of approximately  $170.5 million after
deducting $4.5 million of issuance costs. We will  incur approximately  $15.3 million of additional  annual
interest expense related to the issuance  of the Senior  Notes. This includes $14.7 million  from the
interest on the Senior Notes and $0.6  million  from the amortization of the costs  related to the
Senior Notes.

39

Foreign Currency Exchange Risk

Our operations outside of the U.S. expose us  to  potentially unfavorable  adverse movements in
foreign currency rate changes. We have not entered into forward exchange contracts  related to our
foreign currency exposure. While we  record financial  results and assets and liabilities from  our
international operations in the functional currency, which is generally the local currency, these results
are reflected in our consolidated financial statements in U.S. dollars. Therefore, our reported  results
are exposed to fluctuations in the exchange rates between the U.S. dollar and the local currencies, in
particular the Euro and the Canadian  dollar. In  addition, we fund certain cash flow requirements  of
our  international operations in U.S. dollars.  Accordingly, in the  event that the local currencies
strengthen versus the U.S. dollar to a greater extent than planned the revenues, expenses  and cash flow
requirements associated with our international operations  may  be  significantly higher in  U.S.-dollar
terms than planned. Changes in foreign  currency rates  could adversely  affect  our operating results.

Report of Independent Registered Public  Accounting Firm

The Board of Directors and Stockholders of  Cogent  Communications Group, Inc.

We  have audited the accompanying consolidated balance sheets of Cogent Communications

Group, Inc. and subsidiaries (the ‘‘Company’’) as of December 31, 2009 and 2010, and the related
consolidated statements of operations, changes in  stockholders’ equity, and  cash flows for each of the
three years in the period ended December  31, 2010. Our audits also included the financial statement
schedule listed in the index at 15(a)  2. These financial  statements and schedule are  the responsibility of
the Company’s management. Our responsibility is to express an opinion  on these financial statements
and schedule based on our audits.

We  conducted our audits in accordance with the standards  of  the Public Company Accounting
Oversight Board (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 financial statements referred to above present fairly, in all material respects,

the consolidated financial position of  Cogent Communications Group, Inc. and subsidiaries at
December 31, 2009 and 2010, and the consolidated results  of their  operations and  their cash flows for
each  of the three years in the period  ended  December 31,  2010, in  conformity with U.S.  generally
accepted accounting principles. Also  in  our opinion, the  related financial  statement schedule, when
considered in relation to the basic financial statements taken as a whole,  presents  fairly in all material
respects the information set forth therein.

We  also have audited, in accordance  with the standards of  the Public Company Accounting
Oversight Board (United States), Cogent Communications Group, Inc.’s internal control over financial
reporting as of December 31, 2010, based  on criteria established  in Internal Control—Integrated
Framework issued by the Committee of  Sponsoring  Organizations of the Treadway Commission and  our
report dated February 28, 2011 expressed an unqualified  opinion thereon.

Description of business

Cogent Communications Group, Inc.  (the ‘‘Company’’) is a Delaware  corporation and is

headquartered in Washington, DC. The  Company is a  facilities-based provider  of  low-cost, high-speed
Internet access and Internet Protocol  (‘‘IP’’)  communications services. The Company’s network  is
specifically designed and optimized to transmit data  using  IP. The Company delivers its services to
small and medium-sized businesses, communications service providers and other bandwidth-intensive
organizations in North America and Europe.

The Company offers on-net Internet access services  exclusively through its own  facilities,  which run

all the way to its customers’ premises. Because of its integrated  network architecture, the  Company is
not dependent on local telephone companies to serve  its on-net  customers. The  Company provides
on-net Internet access to its net centric  customers  which include certain bandwidth-intensive users such
as universities, other Internet service  providers,  telephone companies, cable television companies and
commercial content providers at speeds up  to  10 Gigabits per second. These customers generally
receive service in colocation facilities  and  the Company’s data  centers. The Company also offers
Internet access services to its corporate customers in multi-tenant  office buildings typically serving law
firms, financial services firms, advertising  and marketing firms and  other professional services
businesses. The Company operates data centers throughout North America  and Europe that allow
customers to collocate their equipment and access the  Company’s network.

In addition to providing on-net services,  the Company  also provides Internet  connectivity to

customers that are not located in buildings directly connected  to  its network. The Company serves
these off-net corporate customers using  other carriers’ facilities to provide the  ‘‘last mile’’  portion of
the link  from its customers’ premises  to  the Company’s network. The  Company also  provides certain
non-core services that resulted from acquisitions. The Company continues to support  but does not
actively sell these non-core services.

Summary of significant accounting policies

Principles of consolidation

The consolidated financial statements  have been prepared in accordance with United  States
generally accepted accounting principles  and include the  accounts of the Company and  all  of its  wholly
owned and majority-owned subsidiaries. All intercompany balances and  transactions have  been
eliminated in consolidation.

Use of estimates

The preparation of consolidated financial statements in conformity with United States generally
accepted accounting principles requires management to make  estimates and assumptions that affect  the
reported amounts of assets and liabilities and disclosures  of contingent assets  and liabilities at the date
of the consolidated financial statements and the reported amounts of  revenues  and expenses during the
reporting period. Actual results may differ from these estimates.

Revenue recognition and allowance for  doubtful accounts

The Company’s service offerings consist of telecommunications services. Fixed fees are billed
monthly in advance and usage fees are  billed monthly  in arrears. Net revenues from  telecommunication
services are recognized when the services  are  performed,  evidence of an arrangement  exists, the fee is
fixed and determinable and collection is  probable. The probability  of  collection is  determined by an
analysis of a new customer’s credit history and historical payment  patterns  for existing customers.
Service discounts and incentives related to telecommunication  services are recorded  as a reduction of
revenue when granted. Fees billed in connection with  customer installations  are deferred  and
recognized ratably  over the longer of  the contract  term or  the  estimated  customer life  which is
determined by a historical analysis of  customer  retention and the contract  term. The Company  expenses
the direct costs associated with sales  as incurred.

The Company invoices certain customers  for amounts  contractually due for unfulfilled minimum
contractual obligations and recognizes  a  corresponding  sales allowance equal  to  the amount invoiced
resulting in the recognition of no net  revenue at  the time  the customer is billed. The Company
vigorously seeks payment of these amounts.  The Company  recognizes revenue as these  billings are
collected.

The Company establishes an allowance for doubtful accounts  and other  sales  credit adjustments
related to its  trade receivables. Trade  receivables  are recorded at the invoiced amount and  can bear
interest. Allowances for sales credits are  established through a reduction of  revenue, while  allowances
for doubtful accounts are established through a  charge to selling, general, and administrative expenses.
The Company assesses the adequacy  of these  reserves  by evaluating factors, such as the  length  of time
individual receivables are past due, and historical collection experience, and  changes in the  credit
worthiness of its customers. The Company also assesses  the ability of specific  customers  to  meet their
financial obligations and establishes specific allowances related to these  customers. If circumstances
relating to specific customers change or economic conditions change  such that the Company’s past
collection experience and assessment  of the  economic environment are  no longer appropriate, the
Company’s estimate of the recoverability of its trade receivables could  be  impacted.  Accounts
receivable balances are written-off against the  allowance  for  doubtful accounts after  all  means of
collection have been exhausted and the potential for recovery is  considered remote. The  Company
recognized bad debt expense, net of recoveries, of approximately $4.6 million, $4.9 million and
$4.3 million for the years ended December 31,  2008, 2009 and 2010,  respectively.

Network operations

Network operations expenses include costs associated with  service delivery, network  management,
and customer support. This includes  the  costs of personnel and  related  operating expenses associated
with these activities, network facilities costs, fiber and equipment maintenance fees, leased circuit costs,
and access fees paid to building owners.  The  Company estimates its  accruals for  any disputed leased
circuit obligations based upon the nature  and  age of  the dispute. Network operations costs are
impacted by the timing and amounts of disputed circuit costs.  The Company generally records  these
disputed amounts when billed by the  vendor and  reverses  these amounts  when the vendor credit has
been received or the dispute has otherwise  been resolved. The Company  does  not  allocate depreciation
and amortization expense to its network operations  expense.

Foreign currency translation adjustment and comprehensive income  (loss)

The consolidated financial statements  of the Company’s non-U.S. operations are translated into

U.S. dollars using the period-end foreign currency exchange rates  for assets and liabilities and the
average foreign currency exchange rates  for revenues and  expenses. Gains and  losses on  translation of
the accounts are accumulated and reported  as a component of other comprehensive loss in
stockholders’ equity. The Company’s  only  components of ‘‘other comprehensive  loss’’ are currency
translation adjustments for all periods presented.

Financial instruments

The Company considers all highly liquid investments  with an original maturity of three months or

less  at purchase to be cash equivalents.  The Company determines the  appropriate  classification  of its
investments at the time of purchase and  evaluates  such designation at each balance sheet  date.

At December 31, 2009 and December 31, 2010,  the carrying amount of cash and cash equivalents,

accounts receivable, prepaid and other current assets, accounts payable, and accrued expenses
approximated fair value because of the short-term nature of these instruments.  The Company measures
its  cash equivalents at fair value based upon quoted  (Level  1) market prices and  at amortized cost,
which  approximates fair value. Based upon the quoted (Level 1) market price  at December 31, 2010,
the fair value of the Company’s $92.0 million convertible senior notes was approximately  $78.4 million.

The Company was party to letters of  credit totaling  approximately  $0.4 million  as of December 31,

2009 and $0.5 million as of December 31,  2010. These letters of credit  are secured  by  investments
totaling approximately $0.5 million at  December 31,  2009 and  December  31, 2010, that are restricted
and included in other assets.

Concentration of credit risk

The Company’s assets that are exposed to credit  risk  consist of its cash and  cash equivalents, other

assets and accounts receivable. As of December 31,  2009 and 2010, the Company’s cash  equivalents
were invested in demand deposit accounts,  overnight  investments  and money  market  funds.  The largest
individual investment amount was $11.1  million  at December 31, 2009 (demand  deposit account) and
$16.7 million at December 31, 2010 (overnight investment).  The  Company places  its  cash equivalents
and short-term investments in instruments that  meet  high-quality credit standards as specified in the
Company’s investment policy guidelines. Accounts receivable  are due from customers located in  major
metropolitan  areas in the United States,  Europe, Canada and  Mexico.  Receivables  from the Company’s
net centric (wholesale) customers are subject  to  a higher degree of credit  risk than other customers.

The Company relies upon an equipment  vendor for the  majority of its network  equipment and  is

also dependent upon third-party fiber  providers for providing its services to its  customers.

Property and equipment

Property and equipment are recorded at cost and depreciated  once deployed using  the straight-line

method over the estimated useful lives  of the assets.  Useful lives are determined  based on  historical
usage with consideration given to technological changes and trends in the industry that could impact

the asset utilization. System infrastructure costs include the capitalized compensation costs of
employees directly involved with construction activities  and costs incurred by third  party contractors.
Assets  and liabilities under capital leases  are  recorded at  the lesser of the present value of the
aggregate future minimum lease payments  or the fair value of the assets  under lease. Leasehold
improvements include costs associated with building  improvements. The Company determines the
number of renewal option periods, if  any,  included in  the lease term for purposes of amortizing
leasehold improvements based upon its assessment  at the  inception of the lease  of the number of
option periods that are reasonably assured.  Expenditures  for maintenance and repairs  are expensed
as incurred.

Depreciation and amortization periods are  as follows:

beginning when the IRU is ready for use
3 to 8 years

5  years
40 years
3 to 7 years
5 to 10 years

Long-lived assets

The Company’s long-lived assets include  property  and  equipment  and identifiable intangible assets.

These long-lived assets are reviewed  for impairment whenever events or changes in  circumstances
indicate that the carrying amount may not be recoverable. Impairment is determined by comparing the
carrying  value of these long-lived assets  to management’s probability weighted estimate of the future
undiscounted cash flows expected to result  from the use of the assets.  In  the event an impairment
exists, a loss is recognized based on the amount by  which the  carrying value exceeds the fair  value of
the asset, which would be determined  by using  quoted market prices or valuation  techniques such as
the discounted present value of expected  future cash  flows, appraisals, or  other  pricing  models.  In  the
event there are changes in the planned use of the Company’s long-term assets  or the Company’s
expected future undiscounted cash flows are reduced significantly, the  Company’s assessment of its
ability to recover the carrying value of  these assets  could  change.

Asset retirement obligations

The Company’s asset retirement obligations consist of restoration  requirements for certain leased

facilities. The Company recognizes a  liability for the present value of the estimated  fair value  of
contractual obligations associated with the retirement  of long-lived  assets that result from  the
acquisition, construction, development and/or the  normal operation of a  long-lived asset  in the period
incurred. The present value of the fair value of the  obligation is  also  capitalized as property, plant and
equipment and then amortized over the  estimated remaining useful life of the  associated asset.

1. Description of the business and summary of significant accounting policies:  (Continued)

Increases to the asset retirement obligation liability due to the passage of  time are recognized  within
selling, general and administrative expenses in  the Company’s consolidated statements of operations.
Changes in the liability due to revisions  to estimates of future cash  flows are recognized  by  increasing
or decreasing the liability with the offset  adjusting the  carrying amount of the  related long-lived asset.

Equity-based compensation

The Company recognizes compensation expense for its share-based payments granted to its
employees based on their grant date  fair values  with the expense being recognized on a  straight-line
basis over the requisite service period.  The Company begins recording equity-based compensation
expense related to its performance awards  when it is probable that the performance conditions will be
met. Equity-based compensation expense  is recognized  in the statement of  operations in a manner
consistent with the classification of the employee’s salary  and other compensation.  See Note 8 for
additional information related to share-based payments.

Debt with conversion options

On January 1, 2009, the Company adopted the provisions of Accounting Standards Codification

(‘‘ASC’’) ASC 470-20, Debt, ‘‘Debt with Conversion and Other Options’’ (‘‘ASC 470-20’’). ASC  470-20
clarified the accounting for convertible  debt instruments that may be settled  in cash (including partial
cash settlement) upon conversion. ASC  470-20 requires issuers  to  account separately for the liability
and equity components of certain convertible debt instruments in a manner that reflects the  issuer’s
nonconvertible debt borrowing rate when  interest cost is recognized. ASC 470-20 requires bifurcation of
a component of the debt, classification  of  that component in equity  and  the  amortization of the
resulting discount on the debt to be  recognized as part of interest  expense in  the Company’s
consolidated statements of operations.

The Company estimated the fair value of convertible  notes on the issuance date and  on each
purchase date. The fair value that was  assigned to the  liability  component  of convertible notes was
determined using interest rates of similar  debt that excluded a conversion feature and then applying
that effective interest rate to the cash flows associated with the convertible  notes to calculate the
present  value.

Income taxes

The Company’s deferred tax assets or  liabilities are computed based  upon the differences between

financial statement and income tax bases of  assets and liabilities using the enacted  marginal  tax rate.
Deferred income tax expense or benefits are based upon the changes in the assets  or liability from
period to period. At each balance sheet  date, the  Company assesses the likelihood that it will be able
to realize its deferred tax assets. The  Company  considers all  available positive and negative evidence in
assessing the need for a valuation allowance. The Company will reduce its valuation  allowance if the
Company concludes that it is more likely than not that it would  be  able to realize  its deferred tax
assets.

Management determines whether a tax position is more likely  than not to be sustained  upon
examination based on the technical merits of  the position.  Once it  is determined that a  position  meets

this  recognition threshold, the position  is measured to determine the amount of benefit to be
recognized in the financial statements.  The Company’s policy  is to recognize interest and penalties
accrued on any unrecognized tax benefits  as a  component of income tax expense.

The Company or one of its subsidiaries  files income tax returns in  the U.S.  federal jurisdiction and

various state and foreign jurisdictions.  The Company  is subject  to  U.S. federal tax and  state tax
examinations for years from 2005 to 2010. The Company is subject to tax examinations in its foreign
jurisdictions generally for years from 2000  to  2010. Management does not believe there  will be any
material changes in its unrecognized  tax  positions over  the next 12 months.

Basic and diluted net (loss) income per  common share

Basic earnings per share (‘‘EPS’’) excludes dilution for common stock equivalents and is computed
by dividing net income or (loss) available  to common stockholders  by the  weighted-average number of
common shares outstanding for the period. Diluted EPS is based on  the weighted-average number of
shares of common stock outstanding  during  each period,  adjusted for the effect of  common stock
equivalents, if dilutive.

Shares of restricted stock are included  in the computation  of  basic EPS  as they  vest and are

included in diluted EPS, to the extent  they are  dilutive,  determined using the treasury  stock method. As
of December 31, 2008, 2009 and 2010, 1.7 million, 0.4 million and 0.4 million unvested shares of
restricted common stock, respectively, are not  included in  the computation of  diluted (loss) income per
share, as the effect would be anti-dilutive.

Using the ‘‘if-converted’’ method, the shares issuable  upon conversion of  the Company’s 1.00%

Convertible Senior Notes (the ‘‘Convertible Notes’’) were anti-dilutive for the years ended
December 31, 2008, 2009 and 2010. Accordingly, the  impact has been  excluded from the EPS
computations. The Convertible Notes  are  convertible into shares of the Company’s  common stock at an
initial conversion price of $49.18 per share, yielding  1.9 million shares at December 31, 2008,  2009 and
2010, subject to certain adjustments set  forth in the indenture.

The Company computes the dilutive  effect of outstanding  options using  the treasury stock  method.
For the years ended December 31, 2008,  2009 and 2010 options to purchase 1.1 million, 0.4  million  and
0.2 million shares of common stock,  respectively, at  weighted-average exercise  prices of $5.65  and
$12.59 and $17.84 per share, respectively, are not included  in the computation  of  diluted loss per share
as the effect would be anti-dilutive.

$62.6 million, $59.6 million and $56.5  million, for the years ended December 31,  2008, 2009 and 2010,
respectively.

Capitalized construction costs

The Company capitalizes the compensation cost  of  employees directly involved  with its
construction activities. In 2008, 2009  and  2010, the Company capitalized compensation  costs of
$4.1 million, $4.5 million and $5.9 million  respectively.  These amounts are included in system
infrastructure costs.

Asset impairments

During  the first quarter of 2008, the  Company identified  an impaired IRU  asset that resulted  in an

asset impairment charge of $1.6 million.  The  impaired  IRU  asset  was  no  longer in  use and the
Company obtained alternative dark fiber that  serves the  related facilities and customers. As  of
December 31, 2010, the Company’s balance sheet includes a capital lease liability including accrued
interest totaling $2.7 million related  to  this IRU as the requirements for the extinguishment of such
liability have not been met and payments with the vendor are in dispute.

In the three months ended March 31, 2010 the  Company recorded  an  impairment charge  for

certain property and equipment that were  no  longer in use  totaling  $0.6 million.

Asset retirement obligations

In the first quarter of 2010, the Company determined  that its estimates of restoration  costs for its
leased facility asset retirement obligations  were too high based on current  costs to restore  and changes
in the expected timing of the payment of  those costs due  to  the extensions of lease  terms. As  a result,
in the first quarter of 2010, the Company  revised its  estimates of the cash  flows that it believes  will  be
required to settle its leased facility asset  retirement  obligations at  the end of the  respective lease terms,
which  resulted in a reduction to the Company’s asset retirement  obligation liability. As a  result of the
revisions in the estimated amount and timing of cash flows for  its  asset retirement obligations,  in the
three months ended March 31, 2010,  the Company reduced its asset retirement obligation  liability  by
$0.9 million with an offsetting reduction  to  depreciation and amortization  of  $0.7 million and  selling,
general and administrative expenses  of  $0.2 million.

A reconciliation of the amounts related to these obligations is as follows (in thousands):

4. Long-term debt:

Convertible senior notes

In June 2007, the Company issued its  Convertible Notes for  an aggregate principal  amount  of

$200.0 million in a private offering for  resale to qualified institutional buyers  pursuant  to  SEC
Rule 144A. The Convertible Notes mature  on June 15,  2027, are unsecured,  and bear interest at 1.00%
per  annum. The Convertible Notes will  rank equally with any future senior debt  and senior to any
future subordinated debt and will be  effectively subordinated to all existing and future liabilities of the
Company’s subsidiaries and to any secured debt the Company may issue,  to  the extent of the value of
the collateral. Interest is payable in cash semiannually  in arrears on June 15  and December 15,  of  each
year, beginning on December 15, 2007. The Company received net  proceeds from  the issuance of the
Convertible Notes of approximately $195.1 million, after  deducting the original issue discount  of  2.25%
and issuance costs. The discount and  other  issuance  costs are  being  amortized to interest expense using
the effective interest method through June 15, 2014,  which is the earliest put date.

Conversion process and other terms of  the  Convertible Notes

The Convertible Notes are convertible into shares of the Company’s common stock at an initial
conversion price of $49.18 per share, or 20.3355 shares for each  $1,000 principal amount of Convertible
Notes, subject to adjustment for certain events as  set forth in  the indenture. Depending upon the price
of the Company’s common stock at the  time  of conversion, holders of the  Convertible Notes will
receive additional shares of the Company’s common  stock.  Upon  conversion of the Convertible Notes,
the Company will  have the right to deliver shares of its common stock, cash or a  combination  of cash
and shares of its common stock. The  Convertible  Notes are convertible (i) during any fiscal quarter
after the fiscal quarter ending September  30, 2007, if the closing sale price of the  Company’s common
stock for 20 or more trading days in  a  period of 30  consecutive trading  days ending on the last trading
day of the immediately preceding fiscal  quarter exceeds 130%  of the conversion price in effect on  the
last trading day of the immediately preceding fiscal quarter, or (ii) specified corporate transactions
occur, or (iii) the trading price of the Convertible Notes falls  below a certain threshold,  or (iv) if the
Company calls the Convertible Notes for  redemption, or (v)  on or after April  15, 2027, until  maturity.
In addition, following specified corporate  transactions, the Company will  increase the conversion rate
for holders who elect to convert notes  in connection with  such corporate transactions, provided that in
no event may the shares issued upon  conversion, as a  result of adjustment or  otherwise, result  in the
issuance of more than 35.5872 common shares per $1,000  principal  amount.  The Convertible Notes
include an ‘‘Irrevocable Election of Settlement’’ whereby the Company may  choose,  in its sole
discretion, and without the consent of the  holders of  the Convertible  Notes, to waive its right  to  settle
the conversion feature in either cash  or  stock  or in any combination at its option.  The Convertible
Notes may be redeemed by the Company at any time after June 20,  2014 at  a redemption price of
100% of the principal amount plus accrued interest. Holders  of  the Convertible Notes  have the right to
require the Company to repurchase for  cash  all or some  of their notes  on June 15, 2014,  2017 and 2022
and upon the occurrence of certain designated events  at a  redemption price of 100%  of the principal
amount plus accrued interest.

Registration rights

Under the terms of the Convertible Notes, the Company is required to use  reasonable efforts to

file and maintain a shelf registration  statement  with the  SEC covering  the resale of the Convertible

4. Long-term debt: (Continued)

Notes and the common stock issuable on  conversion of the  Convertible Notes. If  the Company fails to
meet these terms, the Company will  be  required  to  pay  special interest on the Convertible  Notes in the
amount of 0.25% for the first 90 days after  the occurrence  of the failure to  meet and  0.50% thereafter.
In addition to the special interest, additional interest of 0.25% per annum will  accrue in the event of
default, as defined in the indenture.  The Company filed a shelf  registration statement registering the
Convertible Notes and common stock  issuable upon  conversion  of  the Convertible Notes  in July  2007.

The Company separately accounted for the  debt  and equity components of its  Convertible Notes in

At each balance sheet date, the Company assesses the likelihood that it  will be able to realize its

deferred tax assets. The Company considers all available positive  and negative  evidence in assessing  the
need for a valuation allowance. At December 31, 2009, the Company concluded that it was more likely
than not that it would be able to realize certain of its deferred  tax  assets primarily as a  result of
expected future taxable income related  to  its  Canadian operations. Accordingly, the Company reduced
a portion of its valuation allowance related to these  deferred tax assets and recorded  an income tax
benefit of $1.5 million in the year ended  December 31,  2009. At December 31, 2010,  the Company
concluded that it was more likely than  not  that  it  would be  able  to  realize the remaining of its
Canadian deferred tax assets related  to  its Canadian operations. Accordingly, the Company  reduced  the
remaining valuation allowance related to these  deferred tax assets and  recorded  an income tax  benefit
of $1.5 million in the year ended December 31, 2010.  As of December 31,  2009 and  2010 the Company
maintained a full valuation allowance against its other deferred tax assets  consisting primarily of net
operating loss carryforwards.

As of December 31, 2010, the Company has combined net operating  loss carry-forwards  of
approximately $1.1 billion. This amount  includes federal and state net operating loss carry-forwards  in
the United States of approximately $376.0  million, net operating loss carry-forwards related  to  its
European, Canadian and Mexican operations of approximately $686.6 million, $6.2 million and
$0.8 million, respectively. Section 382 of  the Internal Revenue Code in  the United  States  limits the
utilization of net operating losses when  ownership changes, as defined by that section, occur.  The

5. Income taxes: (Continued)

Company has performed an analysis  of  its Section  382 ownership changes  and has determined that the
utilization of certain of its net operating  loss carryforwards in  the United  States may  be  limited. The
net operating loss carryforwards in the United States will expire, if unused,  between  2022 and 2029.
The net operating loss carry-forwards related  to  the Canadian operations expire  if  unused, between
2015 and 2027. The net operating loss carry-forwards  related to the Mexican operations  expire if
unused, between 2019 and 2020. The net operating loss  carry-forwards  related to the European
operations include $540.8 million that  do not expire and $145.8 million that expire between  2011
and 2026.

In the normal course of business the  Company takes positions  on  its  tax returns that may  be
challenged by taxing authorities. The Company evaluates  all uncertain  tax  positions  to  assess whether
the position will more likely than not  be  sustained upon  examination.  If the Company determines that
the tax position is more likely than not to be sustained, the  Company records the  amount  of the benefit
that is more likely than not to be realized when  the tax  position  is settled.  This liability, including
accrued interest and penalties, is included  in other long-term  liabilities in the accompanying balance
sheets and was $0.6 million as of December 31,  2009 and $0.9 million as of December 31, 2010. During
the years ended December 31, 2008,  2009  and 2010 the  Company recognized approximately  $0,
$0.1 million and $0.1 million in interest  and penalties related to its  uncertain tax positions. The
Company does not expect the final resolution  of  tax  examinations to have a material impact on the
Company’s financial results in the next 12  months.

Capital leases—fiber lease agreements

The Company has entered into lease agreements  with numerous  providers of dark fiber primarily

under 15–20 year IRUs with additional  renewal terms. Once the Company has accepted  the related
fiber route, leases that meet the criteria  for treatment as capital leases are recorded  as a capital  lease
obligation and an IRU asset. The future  minimum payments under  these agreements are as  follows  (in

Current and potential litigation

The Company has been made aware of several other companies in  its own and  in other industries
that use the word ‘‘Cogent’’ in their  corporate names.  One  company has informed  the Company that it
believes the Company’s use of the name ‘‘Cogent’’ infringes on its intellectual  property rights in that
name. If such a challenge is successful,  the Company could be required to change its name and lose the
value associated with the Cogent name in its markets. Management does not believe such a challenge,
if successful, would have a material impact on  the Company’s business, financial condition or  results of
operations.

In the normal course of business the  Company is  involved in  other legal activities and  claims.
Because such matters are subject to many uncertainties and the outcomes are  not  predictable with
assurance, the liability related to these legal  actions and claims  cannot be determined with certainty.
Management does not believe that such claims  and actions will  have a material impact on the
Company’s financial condition or results  of operations.

Operating leases, maintenance and tenant  license agreements

The Company leases office space, network  equipment sites, and data center facilities under

operating leases. The Company also  enters into building  access agreements  with the landlords of  multi-
tenant  office buildings. The Company  pays fees for the maintenance of its leased dark fiber and  in

Expenses related to these arrangements  were $44.9 million in 2008,  $49.0 million in 2009  and

$53.5 million in 2010.

Unconditional purchase obligations

Unconditional purchase obligations for equipment and services totaled  approximately $10.3 million

at December 31, 2010 and are expected  to  be  fulfilled within one year. As  of  December 31, 2010 the
Company had committed to additional dark fiber  IRU lease agreements totaling approximately
$62.6 million in future payments for  fiber  lease and  maintenance payments to be paid over periods of
up to 20 years. These obligations begin  when the  related fiber is accepted, which is generally expected
to occur  in 2011. Future minimum payments under these  obligations are approximately, $9.2 million,
$3.0 million, $3.0 million, $3.0 million, and $3.0  million for the years ending December  31, 2011 to
December 31, 2015, respectively, and  approximately $41.5  million,  thereafter. In June  2009, the
Company entered into an amended equipment  purchase  agreement with  a vendor.  Under  the
agreement, and prior agreements, the Company is  required to purchase equipment totaling
approximately $23.2 million through  2011. Approximately $6.4 million  remains  to  be  ordered under the
agreement.

Defined contribution plan

The Company sponsors a 401(k) defined contribution plan that, effective in August 2007,  provides
for a Company matching payment. The  Company matching  payments were approximately $0.3 million
for 2008, 2009 and 2010 and were paid in  cash.

7. Stockholders’ equity:

Authorized shares

The Company has 75.0 million shares  of  authorized  $0.001 par  value common stock  and 10,000

authorized but unissued shares of $0.001  par value preferred  stock. The holders of common  stock  are
entitled to one vote per common share  and, subject to any rights of any series of preferred stock,
dividends may be declared and paid  on the  common  stock when  determined by the Company’s Board
of Directors.

7. Stockholders’ equity: (Continued)

Common stock buybacks

In August 2007, the Company’s board of directors  approved  a  $50.0 million common stock buyback

program (the ‘‘Buyback Program’’). In  June 2008, the  Company’s board  of directors approved an
additional $50.0 million of purchases  of the Company’s  common stock under  the Buyback Program to
occur prior to December 31, 2009. In  the  years  ended December 31, 2008 and 2009, the  Company
purchased approximately 4.4 million  and 0.1 million shares of its common stock, respectively, for
approximately $59.3 million and $0.7  million,  respectively, under the Buyback Program. These common
shares were subsequently retired. There  were no purchases of the  Company’s common stock in 2010.

Allied Riser warrants

In connection with the February 2002  merger with Allied Riser, the Company assumed warrants
issued by Allied Riser that could convert  into  approximately 5,200  shares of  the Company’s  common
stock. During the year ended December  31, 2009,  these warrants with a  carrying amount of
approximately $0.8 million expired resulting in  a reduction  to  warrants and a  corresponding  increase to
additional paid-in capital.

8. Stock option and award plan:

Incentive award plan

The Company has an award plan, the 2004 Incentive  Award  Plan, as amended (the ‘‘Award Plan’’),

under which grants of restricted stock  and  options  for common  stock  are made. Stock options granted
under the Award Plan generally vest  over  a four-year  period  and have  a  term of ten  years.  Grants of
shares of restricted stock granted under  the Award  Plan  generally vest over periods ranging  from three
to four years. Compensation expense for  all awards is  recognized over the service period.  Awards with
graded vesting terms are recognized  on  a  straight line basis. Certain option and  share grants provide
for accelerated vesting if there is a change  in control, as defined. For  grants of restricted stock, when
an employee terminates prior to full  vesting the employee  retains their vested  shares and the
employees’ unvested shares are returned  to  the plan.  For grants  of  options for common stock,  when an
employee terminates prior to full vesting the employee  may  elect  to  exercise their vested  options  for a
period of ninety days and any unvested  options  are returned to the  plan. Shares issued to satisfy awards
are provided from the Company’s authorized  shares.

On April 15, 2010, the Company’s stockholders approved  a 1.3 million increase  to  the authorized

shares in the Award Plan. In the second  quarter of 2010, the Company  granted approximately
0.9 million restricted shares to certain  of its employees  that will  vest over a three year period. These
restricted shares were valued at approximately $9.6  million and will be recognized as equity-based
compensation expense on a straight-line basis over the  three year service period. The Company also
granted an additional 0.2 million restricted  shares that are  subject to certain performance conditions
based upon the Company’s operating metrics for 2010, 2011  and  2012. In  November 2010,  the
performance conditions for 2010 were  modified.  The Company  expects to record approximately

performance shares related to 2011 (if  the conditions are met) is approximately $0.9  million  and will be
recognized over the requisite service  period which  is approximately one year. As of  December 31,  2010,
of the 7.1 million authorized shares under  the Award Plan  there were  a total of 0.3 million  shares
available for grant.

The accounting for equity-based compensation expense  requires the Company to make estimates

and judgments that affect its financial statements. These  estimates  include  the following.

Expected Dividend Yield—The Company has never  declared or paid dividends and has no plans to
do so in the foreseeable future.

Expected Volatility—The Company uses its historical volatility for a  period commensurate with the
expected term.

Risk-Free Interest Rate—The Company uses the zero  coupon U.S. Treasury  rate during the
quarter having a term that most closely  resembles the expected  term of the  option.

Expected Term of the Option—The Company  estimates the  expected life  of  the option  term by
analyzing historical stock option exercises and  other relevant data.

Forfeiture Rates—The Company estimates  its forfeiture  rate  based on historical data with further
consideration given to the class of employees to whom the options or shares were granted.

The weighted-average per share grant date fair value  of  options was  $7.20 in 2008, $4.73 in  2009

and $5.44 in 2010.  The following assumptions were used for determining the  fair value of options
granted in the three years ended December 31,  2010:

The weighted average per share grant date  fair value of restricted stock  granted to employees  was
$22.59 in 2008 (0.7 million shares), $6.65 in 2009 (25,008 shares)  and  $9.17 in 2010  (1.2  million shares).
The fair value was determined using  the quoted market price of the Company’s common stock on the
date  of  grant. The fair value of shares  of restricted  stock vested  in the years ended  December 31,  2008,
2009 and 2010 was approximately $3.6 million, $10.8  million,  and  $2.1 million  respectively.

Equity-based compensation expense related  to  stock  options and restricted  stock was approximately

$17.9 million, $8.6 million and $6.6 million for the years ended December 31,  2008, 2009, and 2010,
respectively. The Company capitalized  compensation  expense related to stock options and  restricted
stock of approximately $1.0 million, $1.0 million and $0.7  million for the years ended December  31,
2008, 2009, and 2010, respectively. As  of December  31, 2010 there was approximately $11.7 million of
total unrecognized compensation cost related  to  non-vested  equity-based compensation  awards.  That
cost is expected to be recognized over a  weighted  average period of approximately 2 years.

9. Related party transactions:

Office lease and equipment purchases

The Company’s headquarters is located in an  office building owned by a partnership

(6715 Kenilworth Avenue Partnership).  The two owners of the partnership are the  Company’s Chief
Executive Officer, who has a 51% interest  in the partnership and his wife, who  has a 49%  interest in
the partnership. The Company paid $0.6  million in 2008, 2009  and  2010 in rent and related costs
(including taxes and utilities) to this  partnership  under a  lease that  expires  in August 2012. The dollar
value of the Company’s Chief Executive Officer’s interest in the  lease payments  in 2010 was
$0.3 million. The dollar value of his wife’s interest in  the lease payments  in 2010 was $0.3 million.  If
the Company’s Chief Executive Officer’s interest is combined with that  of  his wife then the  total dollar
value of his interest in the lease payments in 2010 was $0.6 million.

In 2008, 2009 and  2010, the Company purchased approximately $0.1 million,  $13,000 and

$0.1 million of equipment from an equipment vendor. One of the  Company’s directors is also a director
of the equipment vendor.

12. Subsequent events:

Senior Secured Notes

In January 2011, the Company issued its 8.375% Senior  Secured Notes (the ‘‘Senior Notes’’)  due
February 15, 2018, for an aggregate principal amount of $175.0 million in  a private  offering for resale
to qualified institutional buyers pursuant  to SEC  Rule 144A.  The Senior Notes are  secured and bear
interest at 8.375% per annum. Interest is  payable in cash  semiannually  in arrears  on February 15 and
August 15, of each year, beginning on August 15,  2011. The Company received net  proceeds of
approximately $170.5 million after deducting $4.5  million of issuance  costs. The Company intends  to
use the net proceeds from the Senior Notes for general corporate  purposes and/or  repurchases of its
common stock or its Convertible Notes  or a special dividend to its stockholders. The  Company will
incur approximately $15.3 million of additional annual interest expense  related  to  the issuance of the
Senior Notes. This includes $14.7 million from the  interest on the Senior  Notes and $0.6 million from
the amortization of the costs related to the Senior  Notes.

The Senior Notes are fully guaranteed on a senior secured  basis, jointly and severally, by each of

the Company’s existing domestic and future material  domestic subsidiaries, subject  to  certain  exceptions
and permitted liens. Under certain circumstances,  subsidiaries may be released  from these guarantees
without the consent of the holders of  the  Senior Notes. The Senior Notes and the guarantees are
secured by (i) first priority liens on substantially all of Company’s  and its guarantors’ assets,  (ii) all of
the equity interests in any of its domestic subsidiaries and (iii)  65% of  the  equity interests of its
first-tier foreign subsidiaries held by  Company  and  its guarantors. The Senior  Notes and the guarantees
represent Company’s and the guarantors’  senior secured  obligations and effectively rank  equally and
ratably with all of  its and the guarantors’ existing and future  first lien  obligations, to the extent of  the

value of the collateral securing such  indebtedness, subject to permitted liens; are  structurally
subordinated to any existing and future indebtedness  and  liabilities of non-guarantor subsidiaries and
rank equally in right of payment with  all of its and the guarantors’ existing  and future senior
indebtedness.

The Senior Notes may be redeemed, in whole  or in part, at any time prior to February 15, 2015 at
a price equal to 100% of the principal  amount  plus a ‘‘make-whole’’ premium, plus  accrued and  unpaid
interest, if any, to the date of redemption.  The  Senior Notes  are redeemable, in whole or in part,  at
any time on or after February 15, 2015  at the applicable redemption prices  specified under  the
indenture governing the Senior Notes plus accrued  and unpaid interest, if any,  to  the date  of
redemption. In addition, the Company may redeem  up to 35% of  the Senior Notes before February  15,
2014 with the net cash proceeds from  certain equity  offerings. If the Company experiences specific
kinds of changes of control, the Company must  offer  to  repurchase all of the Senior  Notes at a
purchase price of 101% of their principal amount, plus accrued and  unpaid interest, if any, to the
repurchase date.

The indenture governing the Senior Notes, among other things, limits the  Company’s ability and its

guarantors’ ability to incur indebtedness; to pay dividends  or make other  distributions; to make certain
investments and other restricted payments; to create liens; consolidate,  merge, sell or otherwise dispose
of all or substantially all of its assets; to incur restrictions on  the ability of a subsidiary to pay  dividends
or make other payments; and to enter into certain  transactions with  its affiliates.

ITEM 9A. CONTROLS AND PROCEDURES

We maintain disclosure controls and procedures that are designed  to  ensure that information
required to be disclosed in our reports  under the Securities  Exchange Act of 1934, as amended, is
recorded, processed, summarized and reported  within the  time periods specified in  the Securities and
Exchange Commission’s rules and forms, and that  such information is accumulated and communicated
to our management, including our Chief  Executive  Officer  and Chief Financial  Officer, as appropriate,
to allow timely decisions regarding required disclosure.  In designing and evaluating  the disclosure
controls and procedures, management recognized that any  controls and procedures, no  matter how  well
designed  and operated, can provide only  reasonable assurance of achieving the desired control
objectives, and management necessarily was required  to  apply its judgment in evaluating the
cost-benefit relationship of possible controls and procedures.

As required by SEC Rule 13a-15(b), an evaluation was performed  under the supervision and  with

the participation of our management, including our principal executive officer and  our  principal
financial officer, of the effectiveness  of the design and operation of our disclosure controls  and
procedures (as defined in Rules 13a-15(e) and 15d-15(e)  under the Securities Exchange  Act of 1934) as
of the end of the period covered by this  report.  Based  upon that evaluation, our management,
including our principal executive officer and our principal  financial officer, concluded that the  design
and  operation of these disclosure controls and  procedures  were  effective at  the reasonable assurance
level.

There has been no change in our internal controls over financial  reporting during our most recent

fiscal quarter that has materially affected, or is  reasonably likely to materially affect, our internal
controls over financial reporting.

MANAGEMENT’S REPORT ON INTERNAL CONTROL
OVER FINANCIAL REPORTING

We  are responsible for the preparation and integrity  of our published financial statements. The
financial statements have been prepared in accordance with accounting principles generally accepted  in
the United States of America and, accordingly,  include amounts based  on judgments and estimates
made by our management. We also prepared the other  information included in  the annual report  and
are responsible for its accuracy and consistency with the financial  statements.

We  are responsible for establishing and maintaining  a system of internal control over  financial

reporting, which is intended to provide  reasonable assurance to our  management and Board  of
Directors regarding the reliability of  our financial  statements. The  system includes but is not limited to:

(cid:127) a documented organizational structure and division  of responsibility;

(cid:127) established policies and procedures, including a  code of conduct to foster a  strong ethical

climate which is communicated throughout the  company;

(cid:127) regular reviews of our financial statements by qualified individuals; and

(cid:127) the careful selection, training and  development  of  our  people.

There are inherent limitations in the effectiveness of any system of internal  control,  including the

possibility of human error and the circumvention or  overriding of controls.  Also, the  effectiveness of an
internal control system may change over time.  We have implemented  a  system of internal control that
was designed to provide reasonable assurance regarding the reliability  of  financial reporting  and the
preparation of financial statements in accordance with generally accepted accounting  principles.

We  have assessed our internal control system in relation to criteria for  effective internal  control
over financial reporting described in  ‘‘Internal  Control-Integrated Framework’’ issued by the Committee
of Sponsoring Organizations (COSO) of the Treadway  Commission. Based upon these criteria,  we
believe that, as of  December 31, 2010,  our system of  internal  control over financial reporting was
effective.

The independent registered public accounting  firm,  Ernst & Young  LLP, has audited  our  2010
financial statements. Ernst & Young LLP was  given unrestricted access to  all  financial  records and
related data, including minutes of all  meetings of stockholders, the Board of Directors  and committees
of the Board. Ernst & Young LLP has issued  an unqualified  report on  our  2010 financial statements  as
a result of the audit and also has issued  an unqualified  report on  our internal control over  financial
reporting which is attached hereto.

Report of Independent Registered Public  Accounting Firm
On Internal Control over Financial Reporting

The Board of Directors and Stockholders of Cogent  Communications Group, Inc.

We have audited Cogent Communications Group, Inc.’s internal control over financial reporting as
of December 31, 2010, based on criteria established in  Internal  Control—Integrated Framework issued
by the Committee of Sponsoring Organizations of  the Treadway Commission (the COSO  criteria).
Cogent Communications Group, Inc.’s management is responsible for  maintaining effective internal
control over financial reporting, and for its assessment of the effectiveness of internal control over
financial reporting included in the accompanying  Management’s Report  on Internal Control  over
Financial Reporting. Our responsibility is to express an opinion  on the company’s internal  control  over
financial reporting based on our audit.

We conducted our audit in accordance with the  standards of  the Public Company Accounting
Oversight Board (United States). Those  standards require that we  plan and perform the audit to obtain
reasonable assurance about whether  effective  internal control over financial reporting was maintained
in all material respects. Our audit included obtaining an understanding  of internal control  over
financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design
and  operating effectiveness of internal control based  on the assessed risk, and performing such other
procedures as we considered necessary in the circumstances. We  believe that our audit provides a
reasonable basis for our opinion.

A company’s internal control over financial reporting is a process designed to provide  reasonable

assurance regarding the reliability of  financial reporting and the preparation  of  financial  statements  for
external purposes in accordance with generally accepted accounting  principles. A company’s internal
control over financial reporting includes those policies  and procedures that (1)  pertain to the
maintenance of records that, in reasonable detail, accurately and fairly reflect the  transactions and
dispositions of the assets of the company; (2) provide reasonable assurance that transactions  are
recorded as necessary to permit preparation of financial statements in  accordance with generally
accepted accounting principles, and that receipts and expenditures of the company are being made  only
in accordance with authorizations of management and directors of the company; and  (3) provide
reasonable assurance regarding prevention  or timely detection of unauthorized acquisition, use, or
disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over  financial  reporting may not prevent or

detect misstatements. Also, projections  of any  evaluation of  effectiveness to future periods are  subject
to the risk that controls may become inadequate  because  of changes in conditions, or  that  the degree
of compliance with the policies or procedures may deteriorate.

In our opinion, Cogent Communications Group,  Inc. maintained,  in all  material respects, effective

internal control over financial reporting as of December 31, 2010, based  on  the COSO criteria.

We also have audited, in accordance with the  standards of  the Public Company Accounting

Oversight Board (United States), the  consolidated balance  sheets of Cogent Communications
Group, Inc. and subsidiaries as of December 31,  2009 and  2010, and the related consolidated
statements of operations, changes in  stockholders’ equity,  and cash flows for each of the  three years in
the period ended December 31, 2010 of Cogent Communications  Group, Inc. and subsidiaries and  our
report dated February 28, 2011 expressed an unqualified opinion thereon.
