Item 2. Management's Discussion and Analysis of Financial Condition and Results
of Operation

      This report contains certain forward-looking statements and information
relating to FiberNet Telecom Group, Inc. and its subsidiaries ("FiberNet" or
the "Company") that are based on the beliefs of the Company's management, as
well as assumptions made by and information currently available to the
Company's management. When used herein, words such as "anticipate," "believe,"
"estimate," "expect," "intend," and similar expressions, as they relate to the
Company or the Company's management, identify forward-looking statements. Such
statements reflect the current views of the Company with respect to future
events and are subject to certain risks, uncertainties and assumptions,
relating to the operations and results of operations of the Company, the
Company's business strategy, competition and changes in economic cycles, as
well as other factors described herein. Should one or more of these risks or
uncertainties materialize, or should underlying assumptions prove incorrect,
actual results or outcomes may vary materially from those described herein as
anticipated, estimated, expected or intended.

Overview

      FiberNet owns and operates fiber-optic networks designed to provide
comprehensive transmission services to communications service providers in
major metropolitan areas. The Company's technologically advanced, all-optical
network architecture enables it to extend a carrier-class communications
network from carrier points of presence directly to the offices of end-users in
commercial buildings.

      FiberNet's networks originate in carrier point facilities, where the
Company offers colocation space and interconnects with other carriers to
transfer their traffic onto its metropolitan transport networks. Each of the
Company's metropolitan transport networks consists of out-of-building lit
fiber-optic rings that enable FiberNet to establish connectivity between
carrier point facilities and commercial office buildings in the local loop.
FiberNet transports its customers' traffic directly to their retail end-users
located in multi-tenant class A office buildings where the Company has
installed its advanced in-building infrastructure, known as its FiberNet In-
Building Networks, or FINs, by interconnecting its metropolitan transport
network and its FINs. FiberNet's FINs, consist of fully redundant, self-
healing, synchronous optical network, or SONET, rings. The Company refers to
each of the buildings in which it installed a FIN as an on-net building.
FiberNet's FINs provide a central distribution system within on-net buildings,
extending from the basement of the building to each floor.

      FiberNet believes that its metropolitan network solution addresses the
need for bandwidth in the metropolitan local loop, where there is insufficient
network capacity to meet the growing demand for data-intensive applications.
Communications service providers that use the Company's networks are able to
access the high-bandwidth capacity necessary to offer broadband data, voice and
video services without having to build the infrastructure themselves or use
their competitors' networks. In addition, FiberNet's technologically advanced
fiber-optic networks and rapid provisioning times allow its customers to
deliver their services reliably, quickly and efficiently.

      The Company also manages communications access and infrastructure for
commercial office properties nationwide. For the owners and managers of these
buildings, FiberNet provides the in-building infrastructure necessary to meet
the connectivity needs of tenants and controls service providers' access to
these off-net buildings.

      FiberNet commenced operations in the New York metropolitan area in 1999
and began providing services in January 2000. The Company is currently
expanding its operations into Chicago, where it expects to be operational in
the fourth quarter of 2000. The Company also intends to establish its
metropolitan networks in other gateway cities, including Los Angeles, San
Francisco, Boston and Washington D.C.

Results of Operations

Six Months Ended June 30, 2000 Compared to Six Months Ended June 30, 1999

      Revenues. Revenues for the six months ended June 30, 2000 were $1.8
million. The Company generated revenues by providing transport, colocation and
communications access management services to its customers. FiberNet recognized
$1.2 million in transport services, $0.5 million in colocation services and
$0.1 million in communications access management and other services during the
period. During this period, three of the Company's customers, 360networks,
Network Plus and Qwest, accounted for approximately 88% of its revenues. The
Company expects such customer concentration to diminish as it expands its
operations. Prior to the six months ended June 30, 2000, the Company had no
commercial operations and did not generate any revenues.

      Direct Costs. Direct costs for the six months ended June 30, 2000 were
$0.8 million in expenses associated with the operation of the Company's
networks. These costs included on-net building license fees, maintenance and
repair costs, rent expense at carrier point facilities and on-net buildings,
and related utility costs. For the six months ended June 30, 1999, the Company
did not record any direct costs because it was not offering services during
that period.

      Selling, General and Administrative Expenses. Selling, general and
administrative expenses for the six months ended June 30, 2000 were $9.8
million compared to $3.0 million for the six months ended June 30, 1999. This
increase is consistent with the rapid expansion of the Company's operations.
FiberNet has experienced significant growth in personnel costs, marketing and
advertising expenses, and network construction overhead to support its business
strategy. The number of significant transactions that FiberNet has undertaken
this year has also contributed to professional fees, including legal and
accounting costs, of $1.4 million for the six months ended June 30, 2000,
included in selling, general and administrative expenses.

      Stock Related Expense. Stock related expense for the six months ended
June 30, 2000 was $2.2 million. This non-cash expense relates to the granting
of stock options to the Company's employees. FiberNet did not incur any stock
related expense for the six months ended June 30, 1999.

      Depreciation and Amortization. Depreciation and amortization expense for
the six months ended June 30, 2000 was $2.4 million compared to $0.1 million of
depreciation and amortization expense for the six months ended June 30, 1999.
The increase resulted from commencement of the depreciation of certain network
related fixed assets that were placed into service.

      Interest Expense, Net. Interest expense, net for the six months ended
June 30, 2000 was $1.2 million compared to $0.2 million of interest expense,
net for the six months ended June 30, 1999. Interest expense was generated as a
result of borrowings under the Company's senior secured credit facility and its
outstanding capital lease obligations.

      Preferred Stock Dividends. For the six months ended June 30, 2000,
FiberNet paid non-cash dividends on its Series D, E and F Preferred Stock of
$5.5 million in the form of additional shares of each respective series of
preferred stock, which are convertible into shares of the Company's common
stock. The liquidation value of the dividends paid was $0.7 million. The
Company also recorded a beneficial conversion feature of $14.0 million upon the
issuance of the Series G Preferred Stock, which is convertible into common
stock at a price of $10.00 per share, on June 30, 2000. The amounts of the
dividends and the beneficial conversion feature assume a price per share of the
underlying common stock of $17.00. The Company did not record any preferred
dividends during the six months ended June 30, 1999.

      Net Loss Applicable to Common Stockholders. The Company reported a net
loss applicable to common stockholders of $34.2 million for the six months
ended June 30, 2000, compared to a loss of $3.3 million for the six months
ended June 30, 1999. The increase is a result of the aforementioned changes in
the Company's operations.

Three Months Ended June 30, 2000 Compared to Three Months Ended June 30, 1999

      Revenues. Revenues for the three months ended June 30, 2000 were $1.7
million. The Company generated revenues by providing transport, colocation and
communications access management services to its customers. FiberNet recognized
$1.2 million in transport services, $0.4 in colocation services and $0.1
million in communications access management and other services during the
period. During this period, three of the Company's customers, 360networks,
Network Plus and Qwest, accounted for approximately 88% of its revenues. The

      Direct Costs. Direct costs for the three months ended June 30, 2000 were

and related utility costs. For the three months ended June 30, 1999, FiberNet
did not record any direct costs because it was not offering services during
that period.

      Selling, General and Administrative Expenses. Selling, general and
administrative expenses for the three months ended June 30, 2000 were $5.5
million compared to $2.3 million for the three months ended June 30, 1999. This
increase is consistent with the rapid expansion of the Company's operations.
FibertNet has experienced significant growth in personnel costs, marketing and
advertising expenses, and network construction overhead to support its business
strategy.

      Stock Related Expense. Stock related expense for the three months ended
June 30, 2000 was $0.5 million. This non-cash expense relates to the granting
of stock options to the Company's employees. FiberNet did not incur any stock
related expense for the three months ended June 30, 1999.

      Depreciation and Amortization. Depreciation and amortization expense for
the three months ended June 30, 2000 was $1.2 million compared to $0.1 million
of depreciation and amortization expense for the three months ended June 30,
1999. The increase resulted from commencement of the depreciation of certain

June 30, 2000 was $1.3 million compared to $0.2 million of interest expense,
net for the three months ended June 30, 1999. Interest expense was generated as
a result of borrowings under the Company's senior secured credit facility and
its outstanding capital lease obligations.

      Preferred Stock Dividends. For the three months ended June 30, 2000,
FiberNet paid non-cash dividends on its Series D, E and F Preferred Stock of
$2.7 million in the form of additional shares of each respective series of
preferred stock, which are convertible into shares of the Company's common
stock. The liquidation value of the dividends paid was $0.4 million. The

dividends during the three months ended June 30, 1999.

      Net Loss Applicable to Common Stockholders. The Company reported a net
loss applicable to common stockholders of $24.2 million for the three months
ended June 30, 2000, compared to a loss of $2.6 million for the three months
ended June 30, 1999. The increase is a result of the aforementioned changes in
the Company's operations.

Liquidity and Capital Resources

      As a result of FiberNet's developmental activities and the deployment of
its networks and facilities, the Company has incurred significant losses from
inception to date. The Company expects such losses to continue, as it further
executes its business plan and expands its operations. Consequently, the
Company has been dependent upon external sources of capital to fund its
operations. Prospectively, the Company will continue to

                                       3
<PAGE>

incur losses and will not be able to fund its operations with internally
generated funds. Therefore it will require additional, external capital.
Additionally, the Company has no relevant operating history upon which an
evaluation of its performance and prospects can be made. The Company is subject
to unforeseen capital requirements, failure of market acceptance, failure to
establish business relationships, and competitive disadvantages against larger
and more established companies.

      To date, FiberNet has financed its operations through direct equity
investments from its stockholders, the issuance of additional debt and equity
securities in private transactions and by arranging a senior secured credit
facility with a group of lenders. The Company has incurred an EBITDA loss and a
net loss for the six months ended June 30, 2000 of $8.8 million and $34.2
million, respectively, and $3.0 million and $3.3 million, respectively, during
the six months ended June 30, 1999. During the six months ended June 30, 2000,
cash used to fund operating activities was $10.5 million, and cash purchases of
property, plant and equipment were $14.1 million, compared to $4.0 million and
$5.0 million, respectively, for the six months ended June 30, 1999. In
addition, the Company invested $3.0 million in Devnet L.L.C. on April 12, 2000.

      During the six months ended June 30, 2000, the Company received $41.6
million in net cash proceeds from financing activities. The net borrowings
under its senior secured credit facility were $18.4 million. The Company
received $3.3 million in cash proceeds from the exercise of outstanding options
to purchase shares of common stock and $20.0 million from the private placement
of Series G Preferred Stock to Nortel Networks Inc. For the six months ended
June 30, 1999, the Company received $15.6 million in net cash proceeds from
equipment financings and the private placement of certain debt and equity
securities.

      FiberNet's planned operations will require significant, additional
capital to fund equipment purchases, engineering and construction costs,
marketing costs, administrative expenses and other operating activities. The
Company anticipates spending over $100 million during the fiscal year 2000 for
the deployment of its FINs, expansion of its metropolitan transport networks,
the development of additional carrier point facilities and other network
programs and management systems.

      As a result, the Company will require significant additional financing to
complete its networks. FiberNet continues to have on-going discussions with
sources of additional financing. From time to time, FiberNet may consider
private or public sales of additional equity or debt securities and other
financings, depending upon market conditions, in order to finance the continued
operations of its business. To date, no commitments for additional financing
have been obtained. There can be no assurance that the Company will be able to
successfully consummate any such financing on acceptable terms, or at all.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To FiberNet Telecom Group, Inc.:

We have reviewed the accompanying balance sheet of FiberNet Telecom Group, Inc.
and subsidiaries as of June 30, 2000, and the related consolidated statements
of operations for the three-month and six-month periods ended June 30, 2000 and
1999, and the consolidated statements of cash flows for the six-month periods
ended June 30, 2000 and 1999. These financial statements are the responsibility
of the company's management.

We conducted our review in accordance with standards established by the
American Institute of Certified Public Accountants. A review of interim
financial information consists principally of applying analytical procedures to
financial data and making inquiries of persons responsible for financial and
accounting matters. It is substantially less in scope than an audit conducted
in accordance with generally accepted auditing standards, the objective of
which is the expression of an opinion regarding the financial statements taken
as a whole. Accordingly, we do not express such an opinion.

Based on our review, we are not aware of any material modifications that should
be made to the financial statements referred to above for them to be in
conformity with accounting principles generally accepted in the United States
of America.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                  (UNAUDITED)

1. BUSINESS OPERATIONS

      FiberNet Telecom Group, Inc. ("FiberNet" or the "Company") is an all-
optical, facilities-based communications provider focused on providing
wholesale broadband connectivity for data, voice and video transmission on its
state-of-the-art fiber-optic networks in major metropolitan areas. The Company
offers an advanced high bandwidth, fiber-optic solution to support the growing
demand for network capacity in the intra-city market, or local loop. The
Company has established operations in the New York metropolitan area and
expects to expand operations into other target markets, including Chicago, Los
Angeles, San Francisco, Boston and Washington D.C.

      FiberNet is a holding company that owns all of the outstanding common

level holding company. FiberNet Telecom, Inc. owns all of the outstanding
membership interests of Local Fiber, LLC ("Local Fiber"), a New York limited
liability company, and all of the outstanding membership interests of FiberNet
Equal Access, LLC ("Equal Access"), also a New York limited liability company.
The Company conducts its primary business operations through its operating
subsidiaries, Local Fiber and Equal Access.

      The Company was a development stage enterprise through December 31, 1999.
During the fiscal quarter ended March 31, 2000, the Company began offering its
services to customers and recognizing revenues.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

      The interim unaudited consolidated financial statements in this report
have been prepared in accordance with the United States Securities and Exchange
Commission's Regulation S-X and consequently do not include all disclosures
required under generally accepted accounting principles. The interim unaudited
consolidated financial statements should be read in conjunction with the
audited consolidated financial statements of the Company and accompanying notes
for the year ended December 31, 1999, contained in the Company's Annual Report
on Form 10-KSB. The Form 10-KSB includes information with respect to the
Company's significant accounting and financial reporting policies and other
pertinent information. The Company believes that all adjustments of a normal
recurring nature that are necessary for a fair presentation of the results of
the interim periods presented in this report have been made. Certain balances
have been reclassified to conform to the current period presentation. All
significant intercompany balances and transactions have been eliminated.

Use of Estimates

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

Revenue Recognition

      FiberNet generates revenues from selling network capacity and related
services to other communications service providers. The majority of the
Company's revenues are generated on a monthly recurring basis under long-term
contracts, typically three to five years in length. Most of its customers are

                                       12
<PAGE>

obligated to make minimum payments for the utilization of its networks and
facilities. Customers may elect to purchase additional services in excess of
minimum contractual requirements.

      Revenues are derived from three general types of services:

    . Transport services. FiberNet's transport services include the offering
      of broadband circuits on its metropolitan transport networks and in-
      building networks. Over its metropolitan transport networks, the
      Company can provision circuits from one of its carrier point
      facilities to another carrier point facility or to an on-net building
      via an interconnection with its in-building network in that building.
      The Company can also provision circuits vertically between floors in a
      carrier point facility or an on-net building.

    . Colocation facility services. FiberNet's colocation services include
      providing customers with the ability to locate their communications
      and networking equipment at its carrier point facilities in a secure
      technical operating environment. The Company also can provide its
      customers with colocation services in the central equipment rooms of
      certain of its on-net buildings. If a customer purchases colocation
      services, the Company typically requires the customer to make a
      minimum commitment for transport services, as well.

    . Communications access management services. FiberNet's access
      management services include providing its customers with the non-
      exclusive right to market and provide their retail services to tenants
      in its on-net and off-net buildings. Customers typically enter into an
      agreement with the Company to gain access to all or a significant
      number of its properties. For all of its off-net buildings and some of
      its on-net buildings, the Company has the exclusive right to manage
      communications access. Once a customer has entered into an agreement
      with the Company for access services, FiberNet typically requires that
      customer to utilize its in-building network infrastructure for
      connectivity to end-user tenants.

      The Company recognizes revenue on transport services, colocation facility
services and communication access management and other services ratably over
the term of the contract with each customer.

Direct Costs

      The Company classifies expenses of an identifiable activity related to a
contract with a customer that is substantially complete as direct costs. Costs
of contracts in process are accumulated, but there are no interim charges to
income. General and administrative costs are charged to expense as incurred. If
necessary, the estimated loss on an uncompleted contract is expensed in the
period in which it is identified.

Impairment of Long-Lived Assets

      The Company reviews the carrying value of long-lived assets for
impairment whenever events and circumstances indicate the carrying value of an
asset may not be recoverable from the estimated future cash flows expected to
result from its use and eventual disposition. In cases where undiscounted
expected future cash flows are less than the carrying value, an impairment loss
would be recognized equal to an amount by which the carrying value exceeds the
fair value of the assets.

4. SIGNIFICANT AND SUBSEQUENT EVENTS

      On July 31, 2000, FiberNet acquired the remaining 97% of the membership
interests of Devnet L.L.C. ("Devnet") not already beneficially owned by the
Company pursuant to the Agreement and Plan of Reorganization, dated as of June
2, 2000. Devnet manages the communications access and infrastructure for
approximately 40 million square feet of class A commercial real estate in major
markets nationwide. In connection with the acquisition, the Company issued
3,461,162 shares of its Common Stock and paid approximately $15 million in
exchange for approximately 97% of the membership interests in Devnet. The
acquisition will be accounted for under the purchase method of accounting.
FiberNet had previously acquired approximately 3% of the Devnet membership
interests for a purchase price of $3 million in April 2000. The acquisition of
the remaining Devnet membership interests gave the Company control of 100% of
Devnet. The Company has not yet allocated the purchase price of approximately
$60 million to the assets and liabilities of Devnet and will complete the
allocation within one year. In connection with the acquisition, the Company
paid an aggregate of $500,000 to related parties for financial advisory
services.

      On June 22, 2000, the Company amended its master purchase agreement with
Nortel Networks Inc. ("Nortel") to expand the scope of this agreement from
$60.0 million to $260.0 million and to extend the term of the agreement to
2002. On December 31, 1999, FiberNet entered into this master purchase
agreement giving it the right to purchase optical networking equipment and
related services at predetermined volume-based pricing.

      On June 30, 2000, FiberNet issued and sold 2,000,000 shares of Series G
Preferred Stock to Nortel in a private placement for an aggregate purchase
price of $20.0 million. Each share of Series G Preferred Stock was convertible
into one share of Common Stock of FiberNet at $10.00 per share, subject to
anti-dilution adjustments. In connection with this transaction, the Company
recorded a nonrecurring non-cash charge for a beneficial conversion feature in
the amount of $14.0 million to reflect the market price of the Common Stock as
of the date of the issuance.

      On July 31, 2000 FiberNet issued and sold 426,333 shares of Series H
Preferred Stock, $.001 par value per share (the "Series H Preferred Stock") to
Nortel in a private placement for an aggregate purchase price consisting of
$22.5 million in cash plus the cancellation by Nortel of the 2,000,000 shares
of the Series G Preferred Stock, including all accrued and unpaid dividends
thereon. Each share of Series H Preferred Stock is convertible into ten shares
of Common Stock at $10.00 per share, subject to anti-dilution adjustments. This
amount is reflected in the accompanying balance sheet net of the value of
warrants to purchase 425,000 shares of Common Stock of the Company issued in
connection with this transaction. The value of these warrants was estimated on
the date of issuance using an acceptable pricing model. In connection with this
transaction, the Company recorded a nonrecurring non-cash charge for the
beneficial conversion feature in the amount of $12.2 million to reflect the
market price of the Common Stock as of the date of the issuance.

      On August 11, 2000 FiberNet issued and sold 62,500 shares of Series I
Preferred Stock, $.001 par value per share (the "Series I Preferred Stock") to
Nortel in a private placement for an aggregate purchase price of $7.5 million.
Each share of Series I Preferred Stock is convertible into ten shares of Common
Stock at $12.00 per share, subject to anti-dilution adjustments. The Company
anticipates recording a beneficial conversion feature in connection with this
issuance. To date, Nortel has invested a total of $50.0 million in preferred
stock of the Company.

      On May 26, 2000, FiberNet entered into an amended, expanded agreement
with Tishman Speyer Properties, L.P. ("TSP"). Under the agreement, FiberNet
will issue up to 1.6 million shares of its Common Stock to TSP as the Company
enters into license agreements for the deployment and operation of its in-
building networks in certain class A commercial office properties owned or
managed by TSP. As of June 30, 2000, approximately 700,000 shares have been
issued under the agreement for a total value of $6.4 million, based on fair
market value on the date of issuance. This amount is included in deferred
charges on the accompanying balance sheet and is being amortized over 15 years,
the term of the underlying license agreement. In a related transaction, TSP
exchanged a warrant it held for membership interests in Equal Access, an
indirect wholly-owned subsidiary of FiberNet. This exchange had no impact on
the financial statements of the Company.

      On May 23, 2000, FiberNet's board of directors approved, and on July 27,
2000 the Company's stockholders ratified, the adoption of an equity incentive
plan, which amends and restates the Company's 1999 stock option plan. The
equity incentive plan provides for the grant of incentive stock options, non-
qualified stock options and other performance and non-performance based equity
awards, including restricted stock, performance awards, stock appreciation
rights, or SARs, and other types of awards based on the Company's Common Stock.

      On April 27, 2000, the Company began trading its Common Stock on the
Nasdaq National Market System under the ticker symbol "FTGX". Previously, the
Company's Common Stock was quoted on the OTC Bulletin Board under the same
ticker symbol.

      On April 11, 2000, the Company entered into a $75.0 million Senior
Secured Credit Facility (the "Credit Facility") with Deutsche Bank AG New York
Branch, Deutsche Bank Securities Inc., Toronto Dominion (Texas), Inc. and
Nortel. In addition to the initial lenders, First Union National Bank and IBM
Credit Corporation are currently lenders under the Credit Facility. FiberNet
intends to use the funds available under the Credit Facility for the
acquisition and construction of its network infrastructure and for general
corporate purposes. The Credit Facility has a term of four and one-half years,
consisting of revolving availability for the first eighteen months and a term
loan for the remaining three years. The Credit Facility is secured by the
Company's assets, except for the assets pledged in connection with its capital
lease obligations, and contains certain restrictive covenants customary for a
financing of this type. As of June 30, 2000, $21.0 million was outstanding
under the Credit Facility. This amount is included in notes payable in the
accompanying balance sheet net of a discount of $14.9 million. This discount
represents the value of warrants to purchase approximately 1,500,000 shares of
Common Stock of the Company at a price of $18.06 per share issued to the
lenders in connection with the Credit Facility. The discount is being amortized
over the term of the Credit Facility. The fair value of the warrants was
estimated on the date of issuance using an acceptable pricing model.

      In February 2000, FiberNet entered into a two year services agreement
with Bechtel Corporation and Bechtel Associates Professional Corporation for
engineering services, labor, materials and equipment in connection with the
design and installation of the Company's in-building networks.
