for each share of Preferred Stock standing in their name on the books of the
Company. The presence, in person or by proxy, of holders of a majority of the

is necessary to constitute a quorum at the Annual Meeting. The Directors shall
be elected by a plurality of the votes of the shares of capital stock present
in person or represented by proxy at the Annual Meeting and entitled to vote on
the election of directors.

   All shares represented by valid proxies received by the Company prior to the
Annual Meeting will be voted at the Annual Meeting as specified in the proxy,
unless such proxies previously have been revoked. If no specification is made,
the shares will be voted FOR the election of each of the Board's nominees to
the Board of Directors. Unless otherwise indicated by the stockholder, the
proxy card also confers discretionary authority on the Board-appointed proxies
to vote the shares represented by the proxy on any matter that is properly
presented for action at the Annual Meeting. A stockholder giving a proxy has
the power to revoke it any time prior to its exercise by delivering to the
Secretary of the Company a written revocation or a duly executed proxy bearing
a later date, or by attendance at the meeting and voting his shares in person.

   Abstentions and broker non-votes will be counted as shares present for
purposes of determining whether a quorum is present. Abstentions will count as
shares entitled to vote and represented at the Annual Meeting and not voting in
favor of the proposals. Broker non-votes will not count as shares entitled to
vote and represented at the Annual Meeting and will not be included in
calculating the number of votes necessary for approval of the proposals
described below.

                             ELECTION OF DIRECTORS

Description of Board of Directors

   The Bylaws of the Company provide for the Board of Directors to be elected
by a plurality of the votes of the shares present in person or represented by
proxy at the meeting and entitled to vote on the election of directors by the
holders of Class A Common Stock, the holders of Class B Common Stock and the
holders of Preferred Stock, voting together as a single class, with each share
of Class A Common Stock entitled to one (1) vote, each share of Class B Common
Stock entitled to ten (10) votes and each share of Preferred Stock entitled to
one (1) vote. Stockholders of the Company are not entitled to cumulate their
votes in the election of directors.

   The Bylaws of the Company provide that the Board of Directors shall
establish the number of directors which shall not be less than seven (7) nor
more than twenty-one (21). The Board currently consists of eight (8) directors,
all of whom are also nominees for director.

   Each director is to hold office until the next annual meeting of
stockholders and until his successor is duly elected and qualified, subject to
the right of the stockholders to remove any director as provided in the Bylaws.
Any vacancy in the office of a director elected by the holders of Class A
Common Stock, the holders of Class B Common Stock and the holders of Preferred
Stock voting as a single class may be filled by such holders voting as a single
class. In the absence of a stockholder vote, a vacancy on the Board of
Directors may be filled by the remaining directors then in office, even if less
than a quorum, or by the sole remaining director. Any director elected by the
Board of Directors to fill a vacancy shall serve until the next annual meeting
of stockholders and until his successor has been duly elected and qualified. If
the Board of Directors increases the number of directors, any vacancy so
created may be filled by the Board of Directors.

   The persons named as proxies in the enclosed form of proxy were selected by
the Board of Directors and have advised the Board of Directors that, unless
authority is withheld, they intend to vote the shares represented by them at
the Annual Meeting for the election of John J. Rigas, James P. Rigas, Michael
J. Rigas, Timothy J. Rigas, Pete J. Metros, James L. Gray, Peter L. Venetis and
Edward S. Mancini on behalf of all of the stockholders of the Company. All
nominees except Mr. Metros, Mr. Gray, Mr. Mancini and Mr. Venetis were first
elected or appointed as directors of the Company in 1991. Mr. Metros and Mr.
Gray were first elected as directors of the Company in 1997, and Mr. Mancini
and Mr. Venetis were first elected as directors of the Company in 1999.

   The Board of Directors knows of no reason why any nominee for director would
be unable to serve as director. If at the time of the Annual Meeting any of the
named nominees are unable or unwilling to serve as directors of the Company,
the persons named in the proxy intend to vote for such substitutes as may be
nominated by the Board of Directors.

   The following sets forth certain information concerning each nominee for

Compensation Committee Interlocks and Insider Participation

   James L. Gray, Pete J. Metros and Edward S. Mancini serve as members of the
Compensation Committee of the Board of Directors. Neither Mr. Gray, Mr. Metros
nor Mr. Mancini is or has been an officer or employee of the Company or its
subsidiaries.

Board of Directors Compensation

   Directors who are not also employees of the Company each currently receive
compensation from the Company for services as a director at a rate of $1,000
plus reimbursement of expenses for each Board and committee meeting attended.
Non-employee directors are eligible to receive grants under the Company's 1996
Long-Term Incentive Compensation Plan and Adelphia's 1998 Long-Term Incentive
Compensation Plan. Directors who are employees of the Company do not receive
any compensation for services as a director or as a member of Board committees.

Audit Committee Charter

   On June 12, 2000, the Board of Directors of the Company adopted a written
charter for the Audit Committee of the Board, a copy of which is attached as
Appendix B.

                                       7


         REPORT OF THE COMPENSATION COMMITTEE OF THE BOARD OF DIRECTORS

   Executive compensation decisions during the year ended December 31, 2000,
were addressed by the Compensation Committee of the Board of Directors (see
"Election of Directors--Audit and Compensation Committees and Meetings of the
Board of Directors"), composed of three independent, non-employee directors,
Pete J. Metros, James L. Gray and Edward S. Mancini.

   The annual base salary of James P. Rigas, the Chief Executive Officer, is
determined by the Compensation Committees of both the Company and Adelphia
Communications in accordance with Mr. Rigas's employment agreement with
Adelphia and after according significant weight to the input of John J. Rigas,
Chief Executive Officer of Adelphia. The Compensation Committee has recognized
Mr. Rigas's success in achieving the Company's strategic objectives and has
also recognized Mr. Rigas's leadership and vision in formulating strategies for
responding to the challenges of increased regulation and increasing
competition, and for positioning the Company for growth in a regulated
environment. Based on compensation data for other companies, the Compensation
Committee believes that Mr. Rigas's annual base salary and overall compensation
package is lower than the compensation packages (including salary, bonus,
options and deferred compensation) paid to chief executive officers of many
other publicly held telecommunications firms.

   Neither John J. Rigas, Michael J. Rigas nor Timothy J. Rigas were given
salaries or bonuses directly by the Company during the year ended December 31,
2000. Their services, as well as the services of certain other employees of
Adelphia Communications, were paid for directly by Adelphia Communications.
Adelphia Communications has historically charged the Company for the provision
of shared corporate overhead services, but has not charged the Company for the
actual cost of compensating these named executive officers of the Company who
are employees of Adelphia Communications.

Stock Performance Graph

   The following graph compares the percentage change in the cumulative total
shareholder return on the weighted average of the Company's Class A Common
Stock ("Adelphia Business Solutions Class A Common Stock" after October 25,
1999, prior to such date "Hyperion Class A Common Stock") during the period
from May 5, 1998, through December 31, 2000, with the cumulative total return
on the Standard & Poor's 500 Stock Index, a selected peer group of five
companies engaged in the competitive access/telephony industry: Allegiance
Telecom Inc. (Class A); McLeodUSA, Inc. (Class A); RCN Corp. (Class A); US Lec
Corp. (Class A); and XO Communications, Inc. (Class A)(the " Peer Group").* The
returns of each component issuer in the foregoing peer group have been weighted
according to the respective issuer's market capitalization. The comparison
assumes $100 was invested on May 5, 1998, in the Company's Class A Common Stock
and in each of the foregoing indices, and also assumes reinvestment of
dividends.

**   The peer group in the above stock performance graph differs from the peer
     group in the Company's 2000 proxy statement as a result of the bankruptcy
     filings of GST Telecommunications, Inc. and ICG Communications, Inc. Due
     in large part to these bankruptcy filings, shares of these two members of
     the Peer Group are no longer actively traded. Thus, the Company added
     McLeodUSA, Inc. and XO Communications, Inc. to the peer group in this
     proxy statement.

Certain Transactions

   During the year ended December 31, 2000, the Company made demand advances to
Adelphia Communications periodically, for which the Company earned interest of
between 5.15% to 6.33% totaling approximately $6.3 million. During the period
January 1, 2000, to December 31, 2000, the largest amount due from Adelphia
Communications at the end of any quarter was approximately $163.2 million at
March 31, 2000.

   The Company and Adelphia Communications have entered into a registration
rights agreement, as amended, whereby the Company has agreed to provide to
Adelphia Communications and certain permitted transferees, with respect to
common stock owned by them, two demand registration rights per year under
certain conditions, including that any such demand be with respect to shares
with a minimum of $10 million in market value, and with certain piggyback
registration rights in future public offerings of the common stock. Adelphia
Communications' demand registration rights terminate at such time as Adelphia
Communications ceases to hold at least $10 million in market value of common
stock.

   During the year ended December 31, 2000, the Company incurred charges from
Adelphia Communications of approximately $18.5 million for the provision to the
Company of shared corporate overhead services in areas such as personnel,
payroll, management information services, computer services, shared use of
office, aircraft and network facilities and support equipment. The Company
expects that charges for the provision of similar services by Adelphia
Communications to the Company, or by the Company to Adelphia Communications,
will continue to be incurred or charged by the Company in the future. The
transactions related to the provision of these services have been based on
allocation of Adelphia Communications' incremental costs incurred for these
services, and do not necessarily represent the actual costs that would be
incurred if the Company was to secure such services on its own or the costs
which would be charged on a pro-rata allocation of such costs under the
Management Services Agreement between the Company and Adelphia Communications
dated April 10, 1998, with respect to shared corporate overhead service. During
the year ended December 31, 2000, the Company (i) paid Adelphia Communications
or certain of Adelphia Communications' affiliates, fiber lease payments of
approximately $0.3 million, (ii) received from Adelphia Communications $8.6
million in revenue for providing switched services, and (iii) paid to entities
owned by members of the Rigas family who are executive officers of the Company
approximately $11.4 million for property, plant and equipment and services.

   During June 2000, Adelphia Communications exercised a warrant to purchase
913,380 shares of Class A common stock of the Company at a price of $6.15 per
share. Adelphia purchased the warrant in May 1998 from WorldCom in connection
with the Company's IPO. Total proceeds to the Company were approximately $5.6
million.

   During December 2000, the Company sold to a subsidiary of Adelphia
Communications certain network and telecommunications assets. The assets sold
related to six markets in Virginia, Colorado, California and Ohio which the
Company has decided not to pursue as part of its revised business plan. The
aggregate purchase price for these transactions was approximately $87.5 million
plus the assumption of certain liabilities. The Company will manage these
networks for Adelphia on a going forward basis.

   The Company and certain of Adelphia Communications' other subsidiaries and
affiliates are parties to a joint bank credit facility. As part of this
facility, the Company and its subsidiaries have the ability to borrow up to an
aggregate of $500.0 million which, if borrowed, would be guaranteed by other
members of the borrowing group. As of December 31, 2000, a subsidiary of the
Company had borrowed $500.0 million under this credit facility. In addition,
the Company has agreed to pay a subsidiary of Adelphia $15.0 million as a fee
for placing the credit facility. The interest rate at which the Company has
borrowed these funds is 12 1/2%, a portion of which is payable to a subsidiary
of Adelphia. For the year ended December 31, 2000, the Company recorded $21.9
million for interest expense relating to the credit facility, $7.0 million of
which was payable to a subsidiary of Adelphia.

   Proposals of stockholders submitted for consideration at the 2002 Annual
Meeting must be received by the Company no later than March 7, 2002, in order
to be considered for inclusion in the Company's proxy materials for that
meeting. Such proposals must also comply with the requirements set forth in the
rules and regulations of the Securities and Exchange Commission in order to be
eligible for inclusion in the 2002 Annual Meeting proxy materials. Stockholders
who wish to make a proposal at the 2002 Annual Meeting other than by inclusion
in the Company's proxy materials must notify the Company of the matter no later
than May 21, 2002. Notwithstanding the fact that the Company may at its
discretion exclude any untimely proposal, if a stockholder presents a proposal
after May 21, 2002, and that proposal is accepted by the Company, then the
proxies that management solicits for the meeting will have discretionary
authority to vote on the stockholder's proposal if the proposal is otherwise
properly brought before the meeting.

(a) The data presented represents financial information for the Company and its
    consolidated subsidiaries. As of December 31, 2000, three of the Company's
    networks were owned by joint ventures in which it owned an interest of 50%,
    and for which the Company reports its interest pursuant to the equity
    method of accounting consistent with generally accepted accounting
    principles. During December 2000, the Company sold six markets to Adelphia.
    As a result, Statement of Operations and Other Company Data includes such
    networks while Balance Sheet Data excludes such networks as of December 31,
    2000.
(b) Earnings before interest expense, income taxes, depreciation and
    amortization, restructuring charges, other non-cash charges, gain on sale
    of investment, interest income and equity in net loss of joint ventures
    ("EBITDA") and similar measurements of cash flow are commonly used in the
    telecommunications industry to analyze and compare telecommunications
    companies on the basis of operating performance, leverage, and liquidity.
    While EBITDA is not an alternative to operating income as an indicator of
    operating performance or an alternative to cash flows from operating
    activities as a measure of liquidity, all as defined by generally accepted
    accounting principles, and while EBITDA may not be comparable to other
    similarly titled measures of other companies, the Company's management
    believes EBITDA is a meaningful measure of performance.
(c) For the fiscal years ended March 31, 1997 and 1998, the nine months ended
    December 31, 1998, and the years ended December 31, 1999 and 2000, the
    Company's capital expenditures (including capital expenditures relating to
    its wholly-owned operating companies) were $24.6, $68.6, $146.8, $453.2,
    and $712.8 million, respectively, and the Company's investments in its less
    than wholly-owned operating companies were $34.8, $64.3, $69.0, $24.5 and
    $10.4 million, respectively, for the same periods. In addition, during the
    fiscal year ended March 31, 1997, the Company invested $20.0 million in
    fiber assets and a senior secured note.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Overview

   The Private Securities Litigation Reform Act of 1995 provides a "safe
harbor" for forward-looking statements. Certain information, statements or
schedules included in this proxy statement, including Management's Discussion
and Analysis of Financial Condition and Results of Operations, is forward-
looking, such as information relating to the effects of future regulation,
future capital commitments and the effects of competition. Such forward-looking
information involves important risks and uncertainties that could significantly
affect expected results in the future from those expressed in any forward-
looking statements made by, or on behalf of, the Company. These "forward-
looking statements" can be identified by the use of forward-looking terminology
such as "believes," "expects," "may," "will," "should," "intends" or
"anticipates" or the negative thereof or other variations thereon or comparable
terminology, or by discussions of strategy that involve risks and
uncertainties. These risks and uncertainties include, but are not limited to,
uncertainties relating to our ability to successfully market our services to
current and new customers, access markets on a nondiscriminatory basis,
identify, design and construct fiber optic networks, install cable and
facilities (including switching electronics) and obtain rights of way, access
rights to buildings and any required governmental authorizations, franchises
and permits, all in a timely manner, at reasonable costs and on satisfactory
terms and conditions, as well as uncertainties relating to general business and
economic conditions, acquisitions and divestitures, the cost of availability of
capital, government and regulatory policies, the pricing and availability of
equipment, materials, inventories and programming, product acceptance, risks
associated with reliance on the performance and financial condition of vendors
and customers, dependence on the Company's customers and their spending
patterns, the ability of the Company to execute on its business plan and to
design and construct fiber optic networks and related facilities, technological
developments and changes in the competitive environment in which the Company
operates. Persons reading this proxy statement are cautioned that forward-
looking statements herein are only predictions, that no assurance can be given
that the future results will be achieved, and that actual events or results may
differ materially as a result of the risks and uncertainties facing the
Company. Unless otherwise stated, the information contained in this proxy
statement is as of and for the twelve months ended December 31, 2000.
Additional information regarding factors that may affect the business and
financial results of Adelphia Business Solutions can be found in the Company's
filings with the Securities and Exchange Commission, including the prospectus
and most recent prospectus supplement under Registration Statement No. 333-
11142 (formerly No. 333-88927), under the caption "Risk Factors."

   The "Company" or "Adelphia Business Solutions" means Adelphia Business
Solutions, Inc. together with its majority-owned subsidiaries, except where the
context otherwise requires. Unless the context otherwise requires, references
herein to the networks mean (i) the 22 telecommunications networks in operation
or under construction as of May 8, 1998, the date of the Company's initial
public offering (the "Original Markets"), which are owned by wholly-and
majority-owned subsidiaries or by two joint venture partnerships or limited
liability companies managed by the Company and in which the Company holds a 50%
equity interest with one or more other partners, and are broken into two
subcategories, the 14 markets which began operations in 1996 or previously (the
"Class of 1996") and the eight markets which began operations in 1997 or 1998
(the "Class of 1997/98") and (ii) the additional networks operational or under
development subsequent to May 8, 1998 (the "New Markets") which are broken into
two subcategories, those which began operations in 1999 (the "Class of 1999")
and those which began operations in 2000 (the "Class of 2000"). During December
2000, the Company sold to a subsidiary of Adelphia certain network and
telecommunications assets. The assets sold related to six markets in Virginia,
Colorado, California and Ohio which the Company has decided not to pursue as
part of the revised business plan. Network or market information presented in
this proxy statement includes these six markets.

   Adelphia Business Solutions is a leading provider of facilities-based
integrated communications services to customers that include businesses,
governmental and educational end users and other communications services
providers primarily throughout the eastern United States. As of December 31,
2000, the Company offered a full

                                      A-4


range of communications services in 75 markets and expects by the end of the
year 2001 to be offering services in approximately 80 markets, including
substantially all of the top 40 metropolitan statistical areas in the United
States. To serve the Company's customers' broad and expanding communications
needs, the Company has assembled a diverse collection of high-bandwidth, local
and national network assets. The Company intends to integrate these assets with
advanced communications technologies and services in order to provide
comprehensive end-to-end communications services over its networks. The Company
provides customers with communications services such as local switch dial tone
(also known as local phone service), long distance service, high-speed data
transmission and Internet connectivity. The Company's customers have a choice
of receiving these services separately or as bundled packages which are
typically priced at a discount when compared to the price of the separate
services.

   In order to take advantage of the improved economic returns and better
customer service from providing services "on-net," or over the Company's own
network, the Company is in the process of further expanding the reach of its
network system. The Company's Original Markets are principally located in the
eastern half of the United States. Due to the Company's success in operating
and expanding the Original Markets, the Company intends to serve approximately
80 total markets by the end of the year 2001, leveraging the Company's existing
and planned switching platforms and inter-city fiber networks. The Company
believes that the full buildout of this footprint will position it to address
approximately 53% of the 60 million business access lines nationwide, which
currently represent approximately $70 billion in annual revenues. This network
system expansion includes the purchase, lease or construction of local fiber
optic network facilities and the interconnection of all of the Company's
existing and new markets with its own fiber optic facilities. The Company will
also implement various technologies including dense wave division multiplexing,
or DWDM, to provide greater bandwidth capacity on its local and long-haul
network system. Once fully installed, the long-haul fiber optic backbone in the
eastern half of the United States, combined with the Company's local fiber will
support the Company's full line of communication service offerings.

   Financing Transactions. During June 2000, Adelphia exercised a warrant to
purchase 913,380 shares of Class A Common Stock of the Company at a price of
$6.15 per share. Adelphia purchased the warrant in May 1998 from WorldCom in
connection with the Company's IPO. The total proceeds to the Company were $5.6
million.

   The Company and certain of Adelphia's other subsidiaries and affiliates are
party to a joint bank credit facility. As part of this facility, the Company
and its subsidiaries have the ability to borrow up to an aggregate of $500.0
million, which would be guaranteed by other members of the borrowing group,
subject to compliance by the entire borrowing group with certain covenants and
financial tests. As of December 31, 2000, a subsidiary of the Company had
borrowed $500.0 million under this new credit facility. In addition, the
Company has agreed to pay a subsidiary of Adelphia approximately $15.0 million
as a fee for placing the credit facility. The interest rate at which the
Company has borrowed these funds is 12 1/2%, a portion of which is payable to a
subsidiary of Adelphia. For the year ended December 31, 2000, the Company
recorded $7.0 million in interest expense relating to the portion of interest
due to the subsidiary of Adelphia.

   During March 2001, the Company issued and sold 25,222 shares of Class A
common stock to the public in a rights offering at a price of $7.28 per share.
Simultaneously, the Company issued and sold 11,820,070 and 51,459,624 shares of
Class A and Class B common stock, respectively in the rights offering to
Adelphia at a price of $7.28 per share. Total proceeds to the Company were
$460.9 million.

   Acquisition of Partner Interests.  During July 2000, the Company consummated
a purchase agreement with Allegheny Communications Connect, Inc. ("Allegheny")
to acquire its interest in a jointly owned network located in State College,
PA. Consideration paid to Allegheny was 330,000 shares of the Company's Class A
common stock. This purchase increased the Company's ownership in this network
to 100%. The acquisition was accounted for under the purchase method of
accounting. Accordingly, the financial results of the acquired network have
been included in the consolidated results of the Company effective from the
date acquired.

                                      A-5


   Sale of Operating Networks. During December 2000, the Company sold to a
subsidiary of Adelphia certain network and telecommunications assets. The
assets sold related to six markets in Virginia, Colorado, California and Ohio
which the Company has decided not to pursue as part of the revised business
plan. The aggregate purchase price for these transactions was approximately
$87.5 million plus the assumption of certain liabilities. The results of
operations discussed in Management's Discussion and Analysis of Financial
Conditions and Results of Operations include these six markets.

   The increased number and size of the operations of the networks resulted in
increased employee related costs, equipment maintenance costs and expansion
costs.

   Selling, general and administrative expense. Selling, general and
administrative expense increased 94% to $277.2 million for the twelve months
ended December 31, 2000, from $142.6 million in the prior twelve-month period.

   Corporate overhead charges....................................     38,309


   Restructuring Charges. Restructuring charges were $5.4 million for the
twelve months ended December 31, 2000 primarily as a result of the Company's
revised network expansion plan.

   Depreciation. Depreciation and amortization expense increased 76% to $114.6
million during the twelve months ended December 31, 2000, from $65.2 million in
the prior twelve-month period primarily as a result of increased depreciation
resulting from the higher depreciable asset base at the NOCC and the networks,
amortization of deferred financing costs and the acquisition of local partner
interests.

   Interest Income. Interest income decreased to $3.9 million during the twelve
months ended December 31, 2000 from $19.9 million in the prior twelve-month
period as a result of the payment of interest due to the Company from Telergy
received in 1999 as well as decreases in interest income resulting from lower
amounts of cash and cash equivalents and U.S. Government securities.

   Interest Income--Affiliate. Interest income--affiliate decreased 26% to $6.3
million during the twelve months ended December 31, 2000 from $8.5 million in
the prior twelve-month period as a result of lower demand advances made to
Adelphia.

   Interest Expense. Interest expense increased 10% to $81.6 million for the
twelve months ended December 31, 2000, from $74.3 million in the prior twelve-
month period as a result of the draws on the credit facility.

   Interest Expense--Affiliate. Interest expense--affiliate was $7.0 million as
a result of draws on the credit facility discussed previously and incremental
payments of interest to Adelphia in connection with these draws.

   Equity in Net Loss of Joint Ventures. Equity in net loss of joint ventures
decreased by 63% to $2.9 million for the twelve months ended December 31, 2000,
from $7.8 million in the prior twelve-month period as a result of the
consolidation of several joint ventures resulting from the purchase of the
local partners' interests, and the maturing of the remaining joint venture
networks. The decreased net losses of the joint ventures were primarily the
result of increased revenues only partially being offset by startup and other
costs and expenses associated with design, construction, operation and
management of the networks.

   The number of non-consolidated joint venture networks paying management fees
to the Company decreased from four at December 31, 1999 to three at December
31, 2000. These networks paid management and monitoring fees to the Company,
which are included in revenues, aggregating approximately $7.6 million for the
twelve months ended December 31, 2000, an increase of approximately $2.6
million over the prior twelve-month period. The non-consolidated networks' net
losses, including networks under construction, for the twelve months ended
December 31, 1999 and 2000, aggregated approximately $15.2 million and $6.2
million, respectively.

   Preferred Stock Dividends. Preferred stock dividends increased 13% to $35.7
million during the twelve months ended December 31, 2000 from $31.6 million
during the prior twelve-month period. The increase was

                                      A-7


due to a higher outstanding preferred stock base resulting from the payment of
dividends in additional shares of preferred stock.

   Expansion Markets.............................................     10,888
   Network Control Center........................................        701


   The increased number and size of the operations of the networks resulted in
increased employee related costs, equipment maintenance costs and expansion
costs.

   Selling, General and Administrative. Selling, general and administrative
expense increased 251% to $142.6 million for the twelve months ended December
31, 1999 from $40.6 million in the prior twelve-month period.



                                                                     Amounts

                                      A-8


   Depreciation and Amortization. Depreciation and amortization expense
increased 110% to $65.2 million during the twelve months ended December 31,
1999 from $31.1 million in the prior twelve-month period primarily as a result
of increased depreciation resulting from the higher depreciable asset base at
the NOCC and the networks, amortization of deferred financing costs and the
acquisition of local partner interest.

   Interest Income. Interest income for the twelve months ended December 31,
1999 increased 28% to $19.9 million from $15.6 million in the prior twelve-
month period as a result of the payment of interest due the company from
Telergy as discussed previously, offset by decreases in interest income
resulting from lower amounts of cash and cash equivalents and U.S. government
securities.

   Interest Income--Affiliate. Interest income--affiliate remained relatively
unchanged at $8.5 million for the twelve months ended December 31, 2000 as
compared to $8.4 million in the prior twelve-month period.

   Interest Expense. Interest expense increased 43% to $74.3 million during the
twelve months ended December 31, 1999 from $52.0 million in the prior twelve-
month period as a result of the issuance of the 12% Senior Subordinated Notes
due 2007, partially offset by an increase in the amount of interest capitalized
on projects under construction in 1998.

   Equity in Net Loss of Joint Venture. Equity in net loss of joint ventures
decreased by 41% to $7.8 million during the twelve months ended December 31,
1999 from $13.3 million in the prior twelve-month period as a result of the
consolidation of several joint ventures resulting from the purchase of the
local partners' interests, and the maturing of the remaining joint venture
networks. The decreased net losses of the joint ventures were primarily the
result of increased revenues only partially offsetting startup and other costs
and expenses associated with design, construction, operation and management of
the networks.

   The number of non-consolidated networks paying management fees to the
Company decreased from eight at December 31, 1998 to four at December 31, 1999.
These networks paid management and monitoring fees to the Company, which are
included in revenues, aggregating approximately $4.9 million for the twelve
months ended December 31, 1999, an increase of approximately $1.2 million over
the prior twelve-month period. The non-consolidated networks' net losses,
including networks under construction, for the twelve months ended December 31,
1998 and 1999 aggregated approximately $28.4 million and $15.2 million,
respectively.

   Preferred Stock Dividends. Preferred stock dividends increased by 14% to
$31.6 million during the twelve months ended December 31, 1999 from $27.7
million during the prior twelve-month period. The increase is due to a higher
outstanding preferred stock base resulting from the payment of dividends in
additional shares of preferred stock.

Supplementary Network Financial Analysis

   At December 31, 2000, 54 of the 75 operational markets had been in operation
for two years or less, while the remaining 21 markets have been in operation
for more than two years. In order to provide an additional measure of the
financial position, growth and performance of the Company and its networks,
management analyzes the aggregates operational markets based on the year or
years in which the markets became operational. The Original Markets, including
nonconsolidated joint ventures, are broken down into two categories, those
which began operations in 1996 or before and those which began operations in
1997 or 1998. The Expansion Markets are also broken down into two categories,
those which began operations in 1999 and those which began operations in 2000.
The following table provides information relating to the aggregation of those
markets. This financial information, however, is not indicative of the
Company's overall historical financial position or results of operations.

(a) The above table summarizes operating results before the allocation of
    corporate overhead for Adelphia Business Solutions' Original and Expansion
    Markets, grouped by the year or years in which operations commenced.
    Operating Results are presented before an allocation of Corporate Overhead
    for network operating control center, engineering and other administrative
    support functions totaling $23.7 million in the December 2000 quarter and
    $17.1 million in the September 2000 quarter and before a bad debt provision
    for previously recorded revenues of $15.0 million in the December 2000
    quarter. The Original Markets include fourteen markets in the Class of 1996
    and eight markets in the Class of 1997/1998. The Expansion Markets include
    thirty markets in the Class of 1999 and twenty-nine markets in the Class of
    2000.

(b) Earnings before interest, income taxes, depreciation and amortization,
    restructuring charges, other income/expense and non-cash stock compensation
    ("EBITDA") and similar measures of cash flow are commonly used in the
    telecommunications industry to analyze and compare telecommunications
    companies on the basis of operating performance, leverage, and liquidity.
    While EBITDA is not an alternative indicator of operating performance or an
    alternative to cash flows from operating activities as a measure of
    liquidity as defined by GAAP, and while EBITDA may not be comparable to
    other similarly titled measure of other companies, management of Adelphia
    Business Solutions believes that EBITDA is a meaningful measure of
    performance.

(a) The table above summarizes operating results before the allocation of
    corporate overhead for Adelphia Business Solutions' Original and Expansion
    Markets, grouped by the year or years in which operations commenced.
    Operating Results are presented before an allocation of Corporate Overhead
    for network operating control center, engineering and other administrative
    support functions totaling $23.7 million in the December 2000 quarter and
    $14.4 million in the December 1999 quarter and before a bad debt provision
    for previously recorded revenues of $15.0 million in the December 2000
    quarter. The Original Markets include fourteen markets in the Class of 1996
    and eight markets in the Class of 1997/98. The Expansion Markets include
    thirty markets in the Class of 1999 and twenty-nine markets in the Class of
    2000.
(b) Earnings before interest, income taxes, depreciation and amortization,
    restructuring charges, other income/expense and non-cash stock compensation
    ("EBITDA") and similar measures of cash flow are commonly used in the
    telecommunications industry to analyze and compare telecommunications
    companies on the basis of operating performance, leverage, and liquidity.
    While EBITDA is not an alternative indicator of operating performance or an
    alternative to cash flows from operating activities as a measure of
    liquidity as defined by GAAP, and while EBITDA may not be comparable to
    other similarly titled measure of other companies, management of Adelphia
    Business Solutions believes that EBITDA is a meaningful measure of
    performance.

Liquidity and Capital Resources

   The development of the Company's business and the installation and expansion
of the networks, as well as the development of the markets, combined with the
construction and expansion of the Company's NOCC, have resulted in substantial
capital expenditures and investments during the past several years. Capital
expenditures by the Company were $453.2 million and $712.8 million for the
years ended December 31, 1999 and 2000, respectively. Further, investments made
by the Company in nonconsolidated networks and in LMDS licenses were $24.5
million and $88.0 million for the years ended December 31, 1999 and 2000,
respectively. The significant increase in capital expenditures for the year
ended December 31, 2000 is largely attributable to capital expenditures
necessary to develop the Original Markets and the Expansion Markets, as well as
the fiber purchases to interconnect the networks. The Company expects that it
will continue to incur substantial capital expenditures in this development
effort. The Company also expects to continue to fund operating losses as the
Company develops and grows its business. For information regarding recent
transactions affecting the Company's liquidity and capital resources, see
"Financing Transactions" and "Acquisitions of Partners Interests" above.

   The Company has experienced negative operating and investing cash flow since
its inception. A combination of operating losses, substantial capital
investments required to build the Company's networks and its state-of-the-art
NOCC, and incremental investments in the joint ventures has resulted in
substantial negative cash flow.

   Expansion of the Company's Original Markets and services and the development
of Expansion Markets and additional networks and services requires significant
capital expenditures. The Company's operations have required and will continue
to require substantial capital investment for (i) the installation of
electronics for switched services in the Company's networks, (ii) the expansion
and improvement of the Company's NOCC and Original Markets, (iii) the design,
construction and development of Expansion Markets and (iv) the acquisition of
additional ownership interests in the Original Markets. The Company has made
substantial capital investments and investments in joint ventures in connection
with the installation of 5ESS switches or remote switching modules in all of
its Original Markets and has installed regional super switches in certain key
Expansion Markets when such Expansion Markets were operational. To date, the
Company has installed switches in all of its Original Markets and plans to
provide such services in all of its Expansion Markets on a standard switching
platform based on Lucent 5 switch technology. The Company also plans to
purchase its partners' interest in the joint ventures when it can do so at
attractive economic terms. The Company estimates that, in addition to the cash
and cash equivalents on hand and the restricted cash as of December 31, 2000, a
total of approximately $500 million will be required to fund the Company's
capital expenditures, working capital requirements, operating losses and pro
rata investments in the joint ventures during calendar 2001. The Company
currently expects calendar 2001 revenues to be in the range of $500 million,
with first quarter 2001 revenue at approximately the same level as December
2000 quarterly revenue. These expectations include the Company's estimate of
the effect of the revised business plan, the sale of the six markets to
Adelphia and the general economic downturn affecting the United State economy
and its effect on the Company's customers and vendors.

   In addition, there can be no assurance (i) that the Company's future cash
requirements will not vary significantly from those presently planned due to a
variety of factors including acquisition of additional networks, continued
acquisition of increased ownership in its networks, material variances from
expected capital expenditure requirements for Original Markets and Expansion
Markets and development of the LMDS spectrum, or (ii) that anticipated
financings, Local Partner investments and other sources of capital will become
available to the Company on economically attractive terms or at all. In
addition, it is possible that expansion of the Company's networks may include
the geographic expansion of the Company's existing clusters and the development
or acquisition of other new markets not currently planned.

   The Company will need additional funds to fully fund its business plan. The
Company expects to fund its capital requirements through existing resources,
credit facilities and vendor financings at the Company and joint

                                      A-12


venture levels, internally generated funds, equity invested by Local Partners
in joint ventures and additional debt or equity financings, as appropriate, and
expects to fund any potential additional purchase of partnership interests of
Local Partners through existing resources, internally generated funds and
additional debt or equity financings, as appropriate. The Company's ability to
generate cash to meet its future needs will depend generally on its results of
operations and the continued availability of external financing.

   During March 2001, the Company issued and sold 25,322 shares of Class A
common stock, to the public in a rights offering at a price of $7.28 per share.
Simultaneously, the Company issued and sold 11,820,070 and 51,459,624 shares of
Class A and Class B common stock, respectively in the rights offering to
Adelphia at a price of $7.28 per share. Total proceeds to the Company were
$460.9 million.

Recent Accounting Pronouncements

   Statement of Financial Accounting Standards ("SFAS") No. 133, "Accounting
for Derivative Instruments and Hedging Activities," as amended by SFAS 137,
"Accounting for Derivative Instruments and Hedging Activities--Deferral of the
Effective Date of FASB Statement No. 133," and by SFAS 138, "Accounting for
Certain Derivative Instruments and Certain Hedging Activities" is effective for
the Company as of January 1, 2001. SFAS No. 133, as amended, establishes
accounting and reporting standards requiring that every derivative instrument
be recorded in the balance sheet as either an asset or liability measured at
its fair value with changes in fair value reflected in the statement of
operations.

   The Company has no freestanding derivative instruments. In conjunction with
preparing for the implementation of this standard, the Company reviewed
contracts from various functional areas of the Company to identify potential
derivatives embedded in the selected contracts. No embedded derivatives were
identified as a result of this review. The adoption of this statement or any
transition adjustment will not have a significant effect on the Company's
consolidated results of operations or financial position.

   In December 1999, the Securities and Exchange Commission issued Staff
Accounting Bulletin ("SAB") No. 101, which clarified the existing accounting
rules for revenue recognition. SAB No. 101 was adopted by the Company in the
fourth quarter of 2000. The Company's revenue recognition policy did not change
with the adoption of SAB No. 101.

Impact of Inflation

   The Company does not believe that inflation has had a significant impact on
the Company's consolidated operations or on the operations of the joint
ventures in the nine months ended December 31, 1998 and the years ended
December 31, 1999 and 2000.

           QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK

   The Company uses fixed rate debt to fund its working capital requirements,
capital expenditures and acquisitions. These debt arrangements expose the
Company to market risk related to changes in interest rates. The table below
summarizes the fair values and contract terms of the Company's financial
instruments subject to interest rate risk as of December 31, 2000.

                          INDEPENDENT AUDITORS' REPORT

Adelphia Business Solutions, Inc. and Subsidiaries

   We have audited the accompanying consolidated balance sheets of Adelphia
Business Solutions, Inc. and Subsidiaries (the "Company") as of December 31,
1999 and 2000, and the related consolidated statements of operations, of common
stock and other stockholders' equity (deficiency) and of cash flows for the
nine months ended December 31, 1998 and the years ended December 31, 1999 and
2000. These financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.

   We conducted our audits in accordance with auditing standards generally
accepted in the United States of America. 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, such consolidated financial statements present fairly, in
all material respects, the financial position of Adelphia Business Solutions,
Inc. and subsidiaries as of December 31, 1999 and 2000, and the results of
their operations and their cash flows for the nine months ended December 31,

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                (Dollars in thousands, except per share amounts)

1. The Company and Summary of Significant Accounting Policies

Organization and Business

   The consolidated financial statements include the accounts of Adelphia
Business Solutions, Inc. and it's more than 50% owned subsidiaries ("Adelphia
Business Solutions" or the "Company"). All significant intercompany accounts
and transactions have been eliminated in consolidation. The Company was formed
in 1991 and is a majority-owned subsidiary of Adelphia Communications
Corporation ("Adelphia"). On October 25, 1999, the stockholders of the Company
elected to change the name of the Company from Hyperion Telecommunications,
Inc. to Adelphia Business Solutions, Inc., which management believes will
further align the strengths of both companies to develop a single brand in the
communications marketplace.

   Adelphia Business Solutions operates in one segment and is a nationwide
facilities based integrated communications provider, or ICP, that offers
broadband communications solutions, including local switch dial tone, long
distance service, high-speed data transmission and internet connectivity.

   On March 30, 1999, Adelphia Business Solutions elected to change its fiscal
year from March 31 to December 31. The decision was made to conform to general
industry practice and for administrative purposes. The change became effective
for the nine months ended December 31, 1998.

   On May 8, 1998, the Company issued and sold 12,500,000 shares of Class A
common stock at a price to the public of $16.00 per share (the "IPO").
Simultaneously with the closing of the IPO, the Company issued and sold an
additional 3,324,001 shares of Class A common stock to Adelphia at a purchase
price of $15.00 per share (or an aggregate of approximately $49,900). In
addition, at such closing, the Company issued 3,642,666 shares of Class A
common stock to Adelphia in exchange for certain of the Company's indebtedness
and payables with a carrying value of $44,258 owed to Adelphia at a purchase
price of $15.00 per share (or an aggregate of $54,600). In a related
transaction, on June 5, 1998, the Company issued and sold 350,000 shares of
Class A common stock at the $16.00 IPO price pursuant to the underwriters'
over-allotment option in the IPO.

   On November 30, 1999, the Company issued and sold 8,750,000 shares of Class
A common stock at a price to the public of $30.00 per share. Simultaneously
with the closing of this transaction, the Company issued and sold 5,181,350
shares of Class B common stock to Adelphia at a purchase price of $28.95 per
share.

   During March 2001, the Company issued and sold 25,322 shares of Class A
common stock, to the public in a rights offering at a price of $7.28 per share.
Simultaneously, the Company issued and sold 11,820,070 and 51,459,624 shares of
Class A and Class B common stock, respectively in the rights offering to
Adelphia at a price of $7.28 per share. Total proceeds to the Company were
$460,900.

   At December 31, 2000, Adelphia owned approximately 60% of Adelphia Business
Solutions' outstanding common stock and held approximately 90% of the total
voting rights.

   The Company is a leading provider of facilities-based integrated
communications services to customers that include businesses, governmental and
educational end users and other communications services providers primarily
throughout the eastern United States. The Company currently offers a full range
of communications services in 75 markets and expects by the end of the year
2001 to be offering services in approximately 80 markets, including
substantially all of the top 40 metropolitan statistical areas in the United
States. To serve its customers' broad and expanding communications needs, the
Company has assembled a diverse collection of high-bandwidth, local and
national network assets. The Company intends to integrate these assets with

                                      A-21


               ADELPHIA BUSINESS SOLUTIONS, INC. AND SUBSIDIARIES

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)
                (Dollars in thousands except per share amounts)

advanced communications technologies and services in order to provide
comprehensive end-to-end communications services over our own networks. The
Company provides customers with communications services such as local switch
dial tone (also known as local phone service), long distance service, high-
speed data transmission and Internet connectivity. The Company offers its
customers a choice of receiving these services separately or as bundled
packages which are typically priced at a discount when compared to the price of
the separate services.

   To develop the original markets and the new markets, as well as the fiber
purchases to interconnect the networks, the Company expects that it will
continue to incur capital expenditures. In addition to cash and cash
equivalents on hand and the restricted cash as of December 31, 2000, a total of
approximately $500,000 will be required to fund the Company's capital
expenditures, working capital requirements, operating losses and pro rata
investments in the joint ventures during calendar 2001. The Company will need
additional funds to fully fund its business plan. The Company expects to fund
its capital requirements through existing resources, credit facilities and
vendor financings at the Company and joint venture levels, internally generated
funds, equity invested by local partners in joint ventures and additional debt
or equity financings, as appropriate, and expects to fund any potential
additional purchase of partnership interest of local partners through existing
resources, internally generated funds and additional debt or equity financings,
as appropriate. The Company's ability to generate cash to meet its future needs
will depend generally on its results of operations and the continued
availability of external financing.

   Joint ventures, which the Company currently does not control, are accounted
for under the equity method of accounting.

Acquisitions of Partner Interests

   On February 12, 1998, the Company purchased additional partnership interests
in Louisville Lightwave (Louisville and Lexington), NHT Partnership (Buffalo),
New Jersey Fiber Technologies and Hyperion of Harrisburg. As a result, the
Company's ownership in these networks increased to 100%. The aggregate purchase
price was comprised of approximately $45,000 in cash and a warrant, which was
not exercised until May 1998, for 731,624 shares of the Company's Class A
common stock (See Note 6). In addition, the Company paid certain amounts
related to fiber lease financings upon consummation of the purchase of the
additional partnership interests.

   During March 1999, Adelphia Business Solutions consummated purchase
agreements with subsidiaries of Multimedia, Inc. and MediaOne of Colorado Inc.
to acquire their respective interests in jointly owned networks located in the
Wichita, Kansas, Jacksonville, Florida and Richmond, Virginia markets for an
aggregate of approximately $89,750. The agreements increased the Company's
ownership interest in each of these networks to 100%.

   During June 1999, the Company consummated a purchase agreement with Entergy
Corporation ("Entergy"), the parent of its local partner in the Baton Rouge,
Louisianna, Little Rock, Arkansas, and Jackson, Mississippi markets, whereby
Entergy received approximately $36,518 for its ownership interests in these
markets. The agreements increased the Company's ownership interest in each of
these networks to 100%.

   During July 2000, the Company consummated a purchase agreement with
Allegheny Communications Connect, Inc. ("Allegheny") to acquire interests in a
jointly owned network located in State College, Pennsylvania. Consideration
paid to Allegheny was 330,000 shares of the Company's Class A Common Stock.
This purchase increased the Company's ownership in this network to 100%.

   All of the acquisitions described above were accounted for using the
purchase method. Accordingly, the financial results of each acquisition have
been included in the Company's consolidated financial statements from the date
acquired.

   The following unaudited financial information of the Company assumes that
each of the transactions described above had occurred at the beginning of the
preceding period.

Cash and Cash Equivalents

   Cash and cash equivalents consist of highly liquid instruments with an
initial maturity date of three months or less.

Restricted Cash

   Restricted cash consists of highly liquid investments with an initial
maturity date of three months or less reserved for the construction of the
advanced information technology infrastructure under the Company's contract
with the Commonwealth of Pennsylvania. The contract was entered into on May 3,
2000. As part of the contract, the Company was required to place $75.8 million
into a restricted account to be used for the completion on the technology
infrastructure. As of December 31, 2000, the Company had used $21.6 million
towards the completion of the infrastructure.

U.S. Government Securities--Pledged

   U.S. Government Securities--Pledged consist of highly liquid investments
which will be used to pay the first six semi-annual interest payments on the 12
1/4% Senior Secured Notes. Such investments are classified as held-to-maturity
and the carrying value approximates market value.

Accounts Receivable

   An allowance for doubtful accounts of $9,640 and $48,513 is recorded as a
reduction of accounts receivable at December 31, 1999 and 2000, respectively.

Property, Plant and Equipment

   Property, plant and equipment is stated at cost less accumulated
depreciation. Costs capitalized include amounts directly associated with
network engineering, design and construction.

   Provision for depreciation of property, plant and equipment is computed
using the straight-line method over the estimated useful lives of the assets
beginning in the month the asset is available for use or is acquired.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)
                (Dollars in thousands except per share amounts)


   The estimated useful lives of the Company's principal classes of property,
plant and equipment are as follows:


                                                                  
Telecommunications networks......................................... 10-20 years
Network monitoring and switching equipment..........................  5-10 years
Fiber optic use rights..............................................    15 years
Other...............................................................  3-10 years


Revenue Recognition

   The Company recognizes revenue from communications services in the month the
related service is provided. Revenues on billings to customers in advance of
providing services are deferred and recognized when earned. The Company
recognizes revenues related to management and network monitoring of the joint
ventures in the month that the related services are provided. Reciprocal
compensation revenue is an element of switched service revenue, which
represents compensation from Local Exchange Carriers ("LECs") for local
exchange traffic originated by other LECs terminated on the Company's
facilities. Adelphia Business Solutions recognizes revenue based upon
established contracts with the LECs and has established a reserve for a portion
of those revenues that are under dispute.

Significant Customers

   During the nine months ended December 31, 1998, Adelphia Business Solutions'
sales to AT&T and Bell Atlantic represented 11.4% and 10.1% of total revenues,
respectively. During the year ended December 31, 1999, Adelphia Business
Solutions' sales to AT&T and Bell Atlantic represented 8.8% and 14.7% of total
revenues, respectively. During the year ended December 31, 2000, Adelphia
Business Solutions' sales to Verizon represented 15.7% of total revenues.

Basic and Diluted Net Loss per Weighted Average Share of Common Stock

   Basic net loss per weighted average share of common stock is computed based
upon the weighted average number of common shares and warrants outstanding
during the period. Diluted net loss per common share is equal to basic net loss
per common share because the Adelphia Warrant discussed in Note 6 had an
antidilutive effect for the periods presented. Class B common stock warrants to
purchase shares of Class B common stock have been included as shares
outstanding for purposes of the calculation of both basic and diluted net loss
per share for the nine months ended December 31, 1998 and the years ended
December 31, 1999 and 2000.

Other Assets--net

   Deferred debt financing costs, included in other assets, are amortized over
the term of the related debt. The unamortized amounts of deferred debt
financing costs at December 31, 1999 and 2000 were $17,434 and $27,034,
respectively. Included in other assets at December 31, 1999 and 2000 is $44,605
and $122,504, respectively, relating to licenses. These licenses which cover
approximately 60% of the nation's population are a spectrum for a fixed
wireless technology known as local multipoint distribution service ("LMDS") and
are being amortized on a straight line basis over the life of the licenses,
which is 10 years.

Asset Impairments

   Adelphia Business Solutions periodically reviews the carrying value of its
long-lived assets for impairment whenever events or changes in circumstances
indicate that the carrying value of these assets may not be

                                      A-24


               ADELPHIA BUSINESS SOLUTIONS, INC. AND SUBSIDIARIES

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)
                (Dollars in thousands except per share amounts)

recoverable. Measurement of any impairment would include a comparison of
estimated future operating cash flows anticipated to be generated during the
remaining life of the assets with their net carrying value. An impairment loss
would be recognized as the amount by which the carrying value of the assets
exceeds their fair value.

Financial Instruments

   Financial instruments which potentially subject the Company to concentration
of credit risk consist principally of accounts receivable. Concentration of
credit risk with respect to accounts receivable is limited due to the
dispersion of the Company's customer base among different customers and
geographic areas.

   The Company's financial instruments include cash and cash equivalents, notes
payable and redeemable preferred stock. The fair value of the notes payable
exceeded their carrying value by approximately $52,058 at December 31, 1999.
The carrying value of the notes payable exceeded their fair value by
approximately $275,626 at December 31, 2000. The carrying value of the
redeemable preferred stock was equal to its fair value at December 31, 1999.
The carrying value of the redeemable preferred stock exceeded its fair value by
approximately $207,947 at December 31, 2000. The fair values of the financial
instruments were based upon quoted market prices.

Non-cash Financing and Investing Activities

   Capital leases entered into during the nine months ended December 31, 1998,
and the years ended December 31, 1999 and 2000 totaled $1,155, $5,772, and
$17,747 respectively (See Note 5). Dividend requirements applicable to
preferred stock were satisfied by the issuance of an additional 20,624, 30,733
and 34,885 shares of such preferred stock during the nine months ended December
31, 1998 and the years ended December 31, 1999 and 2000, respectively (See Note
5).

Comprehensive Income

   Comprehensive income includes all changes to all changes in stockholder's
equity during a period except those resulting from investments by and
distributions to owners. For the nine months ended December 31, 1998 and the
years ended December 31, 1999 and 2000, the Company's only component of
comprehensive income is its net loss for those periods.

Use of Estimates in the Preparation of Financial Statements

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

Recent Accounting Pronouncements

   Statement of Financial Accounting Standards ("SFAS") No. 133, "Accounting
for Derivative Instruments and Hedging Activities," as amended by SFAS 137,
"Accounting for Derivative Instruments and Hedging Activities--Deferral of the
Effective Date of FASB Statement No. 133," and by SFAS 138, "Accounting for
Certain Derivative Instruments and Certain Hedging Activities" is effective for
the Company as of January 1,

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)
                (Dollars in thousands except per share amounts)

2001. SFAS No. 133, as amended, establishes accounting and reporting standards
requiring that every derivative instrument be recorded in the balance sheet as
either an asset or liability measured at its fair value with changes in fair
value reflected in the statement of operations.

   The Company has no freestanding derivative instruments. In conjunction with
preparing for the implementation of this standard, the Company reviewed
contracts from various functional areas of the Company to identify potential
derivatives embedded in the selected contracts. No embedded derivatives were
identified as a result of this review. The adoption of this statement or any
transition adjustment will not have a significant effect on the Company's
consolidated results of operations or financial position.

   In December 1999, the Securities and Exchange Commission issued Staff
Accounting Bulletin ("SAB") No. 101, which clarified the existing accounting
rules for revenue recognition. SAB No. 101 was adopted by the Company in the
fourth quarter of 2000. The Company's revenue recognition policy did not change
with the adoption of SAB No. 101.

Reclassifications

   Certain December 31, 1998 and 1999 amounts have been reclassified to conform
with the presentation for the year ended December 31, 2000.

   Additions to property, plant and equipment are recorded at cost which
includes amounts for material, applicable labor and overhead and interest.
Capitalized interest amounted to $9,986, $23,282 and $43,609 for the nine
months ended December 31, 1998 and the years ended December 31, 1999 and 2000,
respectively.

3. Investment in Fiber Asset and Senior Secured Note

   On February 20, 1997, the Company entered into several agreements regarding
the leasing of dark fiber in New York state in furtherance of its strategy to
interconnect its networks in the northeastern United States. Pursuant to these
agreements and in consideration of a payment of $20,000, the Company received a
$20,000 Senior Secured Note bearing interest at 22 1/2% (subject to reduction
upon early repayment of principal) due February 2002 (subject to early
redemption options), from Telergy, Inc. ("Telergy"), a right to receive 58,752
shares of Telergy Class A common stock ("Telergy Stock"), and a fully prepaid
lease from a Telergy affiliate

                                      A-26


               ADELPHIA BUSINESS SOLUTIONS, INC. AND SUBSIDIARIES

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)
                (Dollars in thousands except per share amounts)

for an initial lease term of 25 years (with two additional ten-year extensions)
for 24 strands of dark fiber installed or to be installed in a New York fiber
optic telecommunications backbone network. As of December 31, 1998, the Company
included $11,500 and $8,500 in Property, Plant and Equipment and Other Assets,
respectively, as the allocation of the $20,000 payment between the fiber asset
and the Senior Secured Note. No amounts were allocated to the Telergy Stock.
The allocation reflected the Company's estimate of the relative fair values of
the assets acquired.

   On May 15, 1998, Telergy paid the Company $1,000 in exchange for the Telergy
Stock and a gain of $1,000 was recorded by the Company, which is included in
"other income" in the consolidated statement of operations. On November 10,
1998, the Senior Secured Note was amended to mature on January 20, 2000 in
exchange for an indefeasible right to use ("IRU") or long term lease of certain
fiber segments in New York City and along Telergy's long haul fiber segments in
the northeastern United States and Southeastern Canada.

   During May 1999, the Company received $32,329 from Telergy for the repayment
of the Senior Secured Note. The payment represented $20,000 in principal and
$12,329 of interest, which is included in "Interest income" in the consolidated
statement of operations.

4. Investments

   The equity method of accounting is used to account for investments in joint
ventures in which the Company owns less than a majority interest. Under this
method, the Company's initial investment is recorded at cost and subsequently
adjusted for the amount of its equity in the net income or loss of its joint
ventures. Dividends or other distributions are recorded as a reduction of the
Company's investment. Investments in joint ventures accounted for using the
equity method reflect the Company's equity in their underlying net assets.

   The Company's nonconsolidated investments are as follows:

5. Financing Arrangements

Note Payable--Adelphia

   The Company had an unsecured credit arrangement with Adelphia which had no
repayment terms prior to April 15, 1996. On April 15, 1996, $25,000 of the
proceeds from the sale of the 13% Senior Discount Notes (the "Senior Discount
Notes") and Class B common stock warrants were used to repay a portion of this
obligation. Interest expense and fees on this credit arrangement were based
upon the weighted average cost of unsecured borrowings of Adelphia during the
corresponding periods. Effective April 15, 1996, the remaining balance due on
the Note payable-Adelphia was evidenced by an unsecured subordinated note due
April 16, 2003. This obligation had an interest rate of 16.5% per annum.
Interest accrued through May 8, 1998 on the amount outstanding to Adelphia
totaled $10,645. On May 8, 1998, the Note payable--Adelphia and all accrued
interest was converted into shares of Class A common stock simultaneously with
the closing of the IPO (See Note 1).

13% Senior Discount Notes and Class B Common Stock Warrants

   On April 15, 1996, the Company issued $329,000 of 13% Senior Discount Notes
due April 15, 2003 and 329,000 warrants to purchase an aggregate of 1,993,638
shares of its Class B common stock. Prior to April 15, 2001, interest on the
Senior Discount Notes is not payable in cash, but is added to principal.
Thereafter, interest is payable semi-annually commencing October 15, 2001. The
Senior Discount Notes are unsecured and are senior to all future subordinated
indebtedness. On or after April 15, 2001, the Company may redeem, at its
option, all or a portion of the Senior Discount Notes at 106.5%, which declines
to par in 2002, plus accrued interest.

   The holders of the Senior Discount Notes may put the Senior Discount Notes
to the Company at any time upon the occurrence of a Change of Control (as
defined in the Indenture) at a price of 101% of accreted principal. In
addition, the Company will be required to offer to purchase Senior Discount
Notes at a price of 100% with the proceeds of certain asset sales (as defined
in the Indenture). The Indenture stipulates, among other things, limitations on
additional borrowings, issuance of equity instruments, payment of dividends and
other distributions, repurchase of equity interests or subordinated debt, sale-
leaseback transactions, liens, transactions with affiliates, sales of Company
assets, mergers and consolidations.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)
                (Dollars in thousands except per share amounts)


   The Class B common stock warrants are exercisable at $0.00308 per share,
upon the earlier of May 1, 1997 or a Change of Control. Unless exercised, the
Class B common stock warrants will expire on June 30, 2001. The number of
shares and the exercise price for which a warrant is exercisable are subject to
adjustment under certain circumstances. Through December 31, 2000, 298,705
warrants were exercised and converted into 1,810,150 shares of Class B common
stock. The Company received $5 in consideration for the exercise of the
warrants.

   During the nine months ended December 31, 1998, the Company paid $17,313 to
repurchase a portion of the Senior Discount Notes which had a face value of
$25,160 and a carrying value of $17,750. The notes were retired upon repurchase
which resulted in a $237 gain.

12 1/4% Senior Secured Notes

   On August 27, 1997, the Company issued $250,000 aggregate principal amount
of 12 1/4% Senior Secured Notes due September 1, 2004 (the "Senior Secured
Notes"). The Senior Secured Notes are collateralized through the pledge of the
common stock of certain of the Company's wholly-owned subsidiaries. A portion
of the proceeds was invested in U.S. government securities and placed in an
escrow account for payment in full when due of the first six scheduled semi-
annual interest payments on the Senior Secured Notes as required by the
Indenture.

   Interest is payable semi-annually commencing March 1, 1998. The Senior
Secured notes rank pari passu in right of payment with all existing and future
senior Indebtedness (as defined in the Indenture) of the Company and will rank
senior in right of payment to future subordinated Indebtedness of the Company.
On or before September 1, 2000 and subject to certain restrictions, the Company
could redeem, at its option, up to 25% of the aggregate principal amount of the
Senior Secured Notes at a price of 112.25% of principal with the net proceeds
of one or more Qualified Equity Offerings (as defined in the Indenture). As of
September 1, 2000, the Company had not exercised its option to redeem any
senior secured notes. On or after September 1, 2001, the Company may redeem, at
its option, all or a portion of the Senior Secured Notes at 106.125% of
principal which declines to par in 2003, plus accrued interest. The holders of
the Senior Secured Notes may put them to the Company at any time upon the
occurrence of a Change of Control (as defined in the Indenture) at a price of
101% of principal. The Indenture stipulates, among other things, limitations on
additional borrowing, payment of dividends and other distributions, repurchase
of equity interests, transactions with affiliates and the sale of assets.

12 7/8% Senior Exchangeable Redeemable Preferred Stock

   On October 9, 1997, the Company issued $200,000 aggregate liquidation
preference of 12 7/8% Senior Exchangeable Redeemable Preferred Stock due
October 15, 2007 (the "Preferred Stock"). Proceeds to the Company, net of
commissions and other transaction costs, were approximately $194,500.

   Dividends are payable quarterly commencing January 15, 1998 at 12 7/8% of
the liquidation preference of outstanding Preferred Stock. Through October 15,
2002, dividends are payable in cash or additional shares of Preferred Stock at
the Company's option. Subsequent to October 15, 2002, dividends are payable in
cash. The Preferred Stock ranks junior in right of payment to all indebtedness
and other obligations of the Company, its subsidiaries and joint ventures. On
or before October 15, 2000, and subject to certain restrictions, the Company
could redeem, at its option, up to 35% of the initial aggregate liquidation
preference of the Preferred Stock originally issued with the net cash proceeds
of one or more Qualified Equity Offerings (as defined in the Certificate of
Designation) at a redemption price equal to 112.875% of the liquidation
preference per share of

the Preferred Stock, plus, without duplication, accumulated and unpaid
dividends to the date of redemption; provided that, after any such redemption,
there are remaining outstanding shares of Preferred Stock having an aggregate
liquidation preference of at least 65% of the initial aggregate liquidation
preference of the Preferred Stock originally issued. As of October 15, 2000,
the Company had not exercised its option to redeem any Preferred Stock. On or
after October 15, 2002, the Company may redeem, at its option, all or a portion
of the Preferred Stock at 106.438% of the liquidation preference thereof
declining to 100% of the liquidation preference in 2005, plus accrued interest.
The Company is required to redeem all of the shares of Preferred Stock
outstanding on October 15, 2007 at a redemption price equal to 100% of the
liquidation preference thereof, plus, without duplication, accumulated and
unpaid dividends to the date of redemption.

   The holders of the Preferred Stock may put the Preferred Stock to the
Company at any time upon the occurrence of a Change of Control (as defined in
the Certification of Designation) at a price of 101% of the liquidation
preference thereof. The Certificate of Designation stipulates, among other
things, limitations on additional borrowings, payment of dividends and other
distributions, transactions with affiliates and the sale of assets. The Company
may, at its option, on any dividend payment date, exchange in whole, but not in
part, the then outstanding shares of Preferred Stock for 12 7/8% Senior
Subordinated Debentures due October 15, 2007 (the "Exchange Debentures").
Interest, redemption and registration rights provisions of the Exchange
Debentures are consistent with the provisions of the Preferred Stock.

12% Senior Subordinated Notes due 2007

   On March 2, 1999, Adelphia Business Solutions issued $300,000 aggregate
principal amount of 12% Senior Subordinated Notes due 2007 ("Subordinated
Notes"). An entity controlled by members of the Rigas Family, controlling
stockholders of Adelphia, purchased $100,000 aggregate principal amount of the
Subordinated Notes directly from the Company. Proceeds to the Company, net of
discounts, commissions and other transaction costs were approximately $295,000.

   Interest is payable semi-annually commencing May 1, 1999. The Subordinated
Notes rank behind all current and future indebtedness (other than trade
payables), except indebtedness that expressly provides that it is not senior to
the notes. On or before November 1, 2003 and subject to certain restrictions,
the Company could redeem at its option, up to 25% of the aggregate principal
amount of the Subordinated Notes at a price of 112.00% of principal with the
net proceeds of one or more Qualified Equity Offerings (as defined in the
Indenture). On or after November 1, 2003, the Company could redeem, at its
option, all or a portion of the Subordinated Notes at 106.00% of principal
which declines to par in 2005, plus accrued interest. The holders of the
Subordinated Notes may put them to the Company at any time upon the occurrence
of a Change in Control (as defined in the Indenture) at a price of 101.00% of
principal. The Indenture stipulates, among other things, limitations on
additional borrowing, payment of dividends, and other distributions, repurchase
of equity, interests, transactions with affiliates and the sale of assets.

   The expected maturities of the 13% Senior Discount Notes, the 12 1/4% Senior
Secured Notes, the 12 7/8% Senior Exchangeable Redeemable Preferred Stock and
the 12% Senior Subordinated Notes are as follows:

Note Payable

   The Company and certain of Adelphia's other subsidiaries and affiliates are
parties to a joint bank credit facility. As part of their facility, the Company
and its subsidiaries have the ability to borrow up to an aggregate of $500,000
which, if borrowed, would be guaranteed by other members of the borrowing

Long Term Lease Facility

   On December 31, 1997, the Company consummated an agreement for a $24,500
long-term lease facility with AT&T Capital Corporation. The lease facility
provides financing for certain of the switching equipment. Included in the
lease facility is the sale and leaseback of certain switch equipment for which
the Company received $14,876.

Other Debt

   Other debt consists primarily of capital leases entered into in connection
with the acquisition of fiber leases for use in the telecommunications networks
and the long-term lease facility described above. The interest rate on such
debt ranges from 7.5% to 15.0%.

6. Common Stock and Other Stockholders' Equity (Deficiency)

   Adelphia Business Solutions' authorized capital stock consists of
800,000,000 shares of Class A common stock, par value $0.01 per share,
400,000,000 shares of Class B common stock, par value $0.01 per share, and
50,000,000 shares of preferred stock, par value $0.01 per share.

Common Stock

   Shares of Class A common stock and Class B common stock are substantially
identical, except that holders of Class A common stock are entitled to one vote
per share and holders of Class B common stock are entitled to 10 votes per
share on all matters submitted to a vote of stockholders. Each share of Class B
common stock is convertible into one share of Class A common stock. In the
event a cash dividend is paid, the holders of the Class A and the Class B
common stock will be paid an equal amount.

   Prior to the IPO in May 1998, certain former company officers (the
"Officers") were parties to a stockholder agreement, as amended (the
"Stockholder Agreement") with Adelphia. The Stockholder Agreement provided,
among other things, (i) that upon the earlier of (a) the termination of
employment of any of the officers or (b) after October 7, 1998, such officers
could put their shares to Adelphia for fair market value, unless such put
rights were terminated as a result of the registration of the Company's common
stock under the Securities Act of 1933 (the "Securities Act") and (ii) for
certain buy/sell and termination rights and duties among Adelphia and the
Officers. The Stockholder Agreement terminated automatically upon the date of
the IPO.

   The Company also entered into Term Loan and Stock Pledge Agreements ("Loan
Agreements") with each of the Officers. Pursuant to the Loan Agreements, each
Officer borrowed $1,000 from the Company. Each of these loans accrued interest
at the average rate at which the Company could invest cash on a short-term
basis, was secured by a pledge of the borrower's common stock in the Company,
and would mature upon the earlier of (i) October 8, 1998 or (ii) the date of
the IPO and the Officers had the right to sell at least $1,000 worth of their
shares. Each Loan Agreement also provided that any interest accruing on a loan
from the date six months after the date of such loan would be offset by a bonus
payment when principal and interest thereon are due and which would include
additional amounts to pay income taxes applicable to such bonus payment.

   Pursuant to agreements among the Company, Adelphia and the Officers,
simultaneous with the consummation of the IPO, (i) the Stockholder Agreement
and Loan Agreements terminated, (ii) the Officers each repaid the $1,000
borrowed from the Company pursuant to the Loan Agreements plus accrued interest
thereon by each selling 66,667 shares of Class B common stock to Adelphia and
using the proceeds therefrom to repay such loans and (iii) the Company paid to
the management stockholders bonus payments in the amount of interest accruing
on the Loans from the date six months after the date of the Loan Agreements and
any additional amounts necessary to pay income taxes applicable to such bonus
payments.

   On April 8, 1998, the Board of Directors of the Company approved a 3.25-for-
one stock split of its Class A and Class B common stock payable to stockholders
of record on April 28, 1998. The stock split was effected in the form of a
dividend of 2.25 shares for every outstanding share of common stock. All
references in the accompanying consolidated financial statements to the number
of shares of common stock and the par value have been retroactively restated to
reflect the stock split on April 28, 1998.

   On October 25, 1999, the shareholders of the Company approved an amendment
to Article IV of the Amended and Restated Certificate of Incorporation
increasing the number of authorized shares of capital stock from 455,000,000 to
1,250,000,000, the authorized number of Class A common stock from 300,000,000
to

Warrants

 Class A Common Stock Warrants

   On February 12, 1998, the Company consummated an agreement with Lenfest
Telephony, Inc. ("Lenfest") whereby Lenfest received a warrant to obtain
731,624 shares of Class A common stock of the Company (the "Lenfest Warrant")
in exchange for its partnership interest in the Harrisburg, Pennsylvania
network. The Lenfest Warrant was exercised during May 1998 for no additional
consideration.

 Class B Common Stock Warrants

   The Class B common stock warrants were issued on April 15, 1996 in
connection with the issuance of the Senior Discount Notes (See Note 5).

 Adelphia Warrant

   On June 13, 1997, the Company entered into agreements with MCI. Pursuant to
these agreements the Company is designated MCI's preferred provider for new end
user dedicated access circuits and conversions of end user dedicated access
circuits as a result of conversions from the incumbent LEC in the Company's

markets. Adelphia Business Solutions also has certain rights of first refusal
to provide MCI with certain communications services. Under this arrangement,
the Company issued a warrant to purchase 913,380 shares of Class A common stock
for $6.15 per share to MCI (the "MCI Warrant") representing 2 1/2% of the
common stock of the Company on a fully diluted basis. MCI could receive
additional warrants to purchase up to an additional 6% of the shares of the
Company's Class A common stock, on a fully diluted basis, at fair value, if MCI
met certain purchase volume thresholds over the term of the agreement.

   In connection with the IPO and the related over-allotment option, the
Company and MCI entered into an agreement that provides as follows with respect
to the MCI Warrant and MCI's right to receive additional MCI warrants as a
result of the IPO (the "Additional MCI Warrants"): (i) the Additional MCI
Warrants, totaling 508,121 shares, issued with respect to the shares sold to
the public in the IPO, the over-allotment option and with respect to the
Adelphia shares purchased will have an exercise price equal to the lower of
$6.15 per share or the price per share to the public in the IPO (the "IPO
Price"), and (ii) Adelphia purchased from MCI the MCI Warrant and the
Additional MCI Warrants for a purchase price equal to the number of Class A
common stock shares issuable under the warrants being purchased times the IPO
Price minus the underwriting discount, less the aggregate exercise price of
such warrants. Furthermore, in consideration of the obligations undertaken by
Adelphia to facilitate the agreements between MCI and Adelphia Business
Solutions, the Company paid to Adelphia a fee of $500 and issued a warrant to
Adelphia, which expires three years after its issuance, to purchase 200,000
shares of Class A common stock at an exercise price equal to the IPO Price.
During June 2000, Adelphia exercised a warrant to purchase 913,380 shares of
Class A Common Stock of the Company at a price of $6.15 per share. Total
proceeds to the Company were $5,611.

 Long Term Incentive Compensation Plan

   On October 3, 1996, the Board of Directors and stockholders of the Company
approved the Company's 1996 Long-Term Incentive Compensation Plan (the "1996
Plan"). The 1996 Plan provides for the grant of (i) options which qualify as
"incentive stock options" within the meaning of Section 422 of the Internal
Revenue Code of 1986, as amended, (ii) options which do not so qualify, (iii)
share awards (with or without restrictions on vesting), (iv) stock appreciation
rights and (v) stock equivalent or phantom units. The number of shares of Class
A common stock available for issuance initially was 5,687,500. Such number is
to increase each year by 1% of outstanding shares of all classes of the
Company's common stock, up to a maximum of 8,125,000 shares. Options, awards
and units may be granted under the 1996 Plan to directors, officers, employees
and consultants. The 1996 Plan provides the incentive stock options must be
granted with an exercise price of not less than the fair market value of the
underlying common stock on the date of grant. Options outstanding under the
Plan may be exercised by paying the exercise price per share through various
alternative settlement methods.

   In August 1999, the Company issued under the 1996 Plan to each of John J.
Rigas, Michael J. Rigas, Timothy J. Rigas and James P. Rigas (i) stock options
(the "Rigas Options") covering 100,000 shares of Class A common stock, which
options will vest in equal one-third amounts on the third, fourth and fifth
year anniversaries of grant (vesting conditioned on continued service as an
employee or director) and which shall be exercisable at $16.00 per share and
(ii) stock awards (the "Rigas Grants") covering 100,000 shares of Class A
common stock, which stock awards will vest in equal one-third amounts on the
third, fourth and fifth year anniversaries of grant (vesting conditioned on
continued service as an employee or director).

   In addition to the Rigas Options, certain employees have been granted
options to purchase shares of Class A common stock at prices equal to the fair
market value of the shares on the date the option was granted. Options are
exercisable beginning from immediately after granting and have a maximum term
of ten years.

   SFAS No. 123, "Accounting for Stock-Based Compensation," ("SFAS 123")
requires the Company to disclose pro forma information regarding option grants
made to its employees. SFAS 123 specifies certain valuation techniques that
produce estimated compensation charges that are included in the pro forma
results below. These amounts have not been reflected in the Company's statement
of operations, because the Company applies the provisions of APB 25,
"Accounting for Stock Issued to Employees," which specifies that no
compensation charge arises when the exercise price of the employees' stock
options equals or exceeds the market value of the underlying stock at the grant
date, as in the case of options granted to the Company's employees.

   SFAS 123 pro forma numbers are as follows:

   Under SFAS 123, the fair value of each option grant is estimated on the date
of the grant using the Black-Scholes option pricing model with the following
weighted average assumptions



                                                              Employee Stock

                                                            -------------------
                                                            1999       2000
                                                            -------------------
                                                             
   Expected dividend yield.................................   0%         0%
   Risk-free interest rate................................. 6.93%  5.10% -6.20%
   Expected volatility.....................................  50%    106% -116%
   Expected life (in years)................................  5.2        9.1


   The Black-Scholes option valuation model was developed for use in estimating
the fair value of traded options that have no vesting restrictions and are
fully transferable. In addition, option valuation models require the input of
highly subjective assumptions including the expected stock price volatility.
Because the Company's employee stock options have characteristics significantly
different from those of traded options, and because changes in the subjective
input assumptions can materially affect the fair value estimate, in
management's opinion the existing models do not necessarily provide a reliable
single measure of the fair value of the Company's options.

   In addition to the stock options and Rigas Grants, the Company issued 58,500
and 98,500 shares of Class A common stock to certain employees for the nine
months ended December 31,1998 and the year ended December 31, 2000,
respectively, resulting in the recognition of $761 and $387 of compensation
expense, respectively.

7. Commitments and contingencies

   The Company rents office space, node space and fiber under leases with terms
which are generally less than one year or under agreements that are generally
cancelable on short notice. Total rental expense under all operating leases
aggregated $1,893, $10,166 and $22,606 for the nine months ended December 31,
1998 and the years ended December 31, 1999 and 2000, respectively.

   The minimum future lease obligations under the noncancelable operating
leases as of December 31, 2000 are approximately:

   During July 1999, the Company purchased the naming rights to the NFL
Football Tennessee Titans stadium in Nashville, Tennessee. The term of the
naming rights contract is for 15 years and requires the Company to pay $2,000

   The communications industry and Adelphia Business Solutions are subject to
extensive regulation at the federal, state and local levels. On February 8,

since the Communications Act of 1934. Management of the Company is unable to
predict the effect that the Telecommunications Act, related rulemaking
proceedings or other future rulemaking proceedings will have on its business
and results of operations in future periods.

   Adelphia Business Solutions has entered into a series of agreements with
several local and long-haul fiber optic network providers. These agreements
provide the Company with ownership or an IRU to local and long-haul fiber optic
cable. The Company believes this will allow it to expand its business strategy
to include on-net provisioning of regional, local and long distance, internet
and data communications and to cost-effectively further interconnect its
markets in the eastern half of the United States.

   The estimated obligations under these arrangements as of December 31, 2000
are approximately

   Thereafter..........................................................   13,107


   In addition to the amounts due under the agreements for the fiber optic
cable, the Company is also required to pay certain fiber optic network
providers for pro-rated maintenance and rights of ways fees on a yearly basis.

and taxation. Such costs were estimated by Adelphia and do not necessarily
represent the actual costs that would be incurred if the Company were to secure
such services on its own.

   Fiber lease expense represents amounts paid to various subsidiaries of
Adelphia for the utilization of existing cable television plant for development
and operation of the consolidated operating networks.

   Amortization of deferred debt financing costs for the year ended December
31, 2000 relate to the amortization of the $15,000 placement fee paid to a
subsidiary of Adelphia.

   During the nine months ended December 31, 1998 and the years ended December
31, 1999 and 2000, the Company paid $1,044, $7,577 and $11,387 respectively, to
entities owned by certain shareholders of Adelphia primarily for property,
plant and equipment and services at market rates.

   During the nine months ended December 31, 1998 and the years ended December
31, 1999 and 2000, the Company made demand advances to Adelphia. At December
31, 1998, 1999 and 2000, $4,950, $392,629 and $0, respectively were outstanding
under this agreement. The Company received interest on such advances at a rate
of between 5.15% and 6.33%, which is included in interest income--affiliate in
the consolidated statement of operations. Demand advances represent cash held
by Adelphia's centralized cash management system immediately available to the
Company for any corporate purpose on demand.

   During December 2000, the Company sold to a subsidiary of Adelphia certain
network and telecommunications assets. The assets sold related to six markets
in Virginia, Colorado, California and Ohio which the Company has decided not to
pursue as part of the revised business plan. Network or market information
presented in this proxy statement includes these six markets. The aggregate
purchase price for these transactions was approximately $87,500plus the
assumption of certain liabilities. The Company will manage these networks for
Adelphia on a going forward basis.

9. Employee Benefit Plan

   The Company participates in the Adelphia 401(k) and stock value plan which
provides that eligible full-time employees may contribute from 2% to 16% of
their pre-tax compensation subject to certain limitations. The Company matches
contributions up to 1.5% of each participant's pre-tax compensation. For the
Nine Months ended December 31, 1998 and the years ended December 31, 1999 and
2000, the Company's matching contributions were $87, $401 and $855,
respectively. The 401(k) and stock value plans also provide for certain stock

   In addition to the 401(k) and stock value plan, the Company participates in
an Adelphia stock incentive plan which provides certain management level
employees with compensation bonuses based on a weighted average of Adelphia
Class A common stock and Adelphia Business Solutions Class A common stock
performance. Costs to the Company associated with this plan were approximately
$1,746 and $261 for the years ended December 31, 1999 and 2000, respectively.

10. Income Taxes

   For the nine months ended December 31, 1998 and the years ended December 31,
1999 and 2000, Adelphia Business Solutions will not be included within
Adelphia's consolidated federal income tax return. Deferred income taxes
reflect the net tax effects of (a) temporary differences between the carrying
amounts of assets and liabilities for financial reporting purposes and the
amounts used for income tax purposes and (b) operating loss carryforwards.

   At December 31, 2000, the Company had net operating loss carryforwards for
federal income tax purposes of $573,127, which expire as follows:

1999 and 2000 was an increase of $65,297 and $125,554, respectively. The
Company recorded the valuation allowance to reduce the deferred tax asset to
zero because the Company does not believe that it is more likely than not that
it will realize its deferred tax asset.

11. Restructuring Charges

   During December 2000, the Company initiated a plan to reduce its network
expansion plan from its former target of 175 to 200 markets nationwide by the
end of 2001 to a new target of approximately 80 markets, thereby canceling
plans to enter or continue operations in approximately 120 markets. In January
2001, the Company reduced its national staff by approximately 8% as a result of
the Company's revised business plan. Most of the affected employees were
located in markets in which the Company has stopped expansion. For the year
ended December 31, 2000, the Company recorded a charge of approximately $5,420
to cover a portion of the costs associated with this revised business plan.
Approximately $4,568 of the charge relates to cash expenses relating to the
termination of lease contracts in the eliminated markets.

   Approximately $852 of the charge relates to severance for certain executive
employees. No amounts were recorded for severance for terminated non-executive
employees as of December 31, 2000. In addition, no amounts were recorded for
the disposal of assets as most equipment deployed in the terminated markets can
be redeployed in the Company's surviving markets, at little or no incremental
costs.

Dividends

   The Company has never declared any cash dividends on any of its respective

stock.

Sale of Unregistered Securities

   During June 2000, Adelphia exercised a warrant to purchase 913,380 shares of
Class A common stock of the Company at a price of $6.15 per share. Adelphia
purchased the warrant in May 1998 from WorldCom in connection with the
Company's IPO. Total proceeds to the Company were $5.6 million. These shares
were sold in reliance on the exemption under section 4(2) of the Securities
Act.

   In July 2000, Adelphia Business Solutions issued 330,000 shares of Class A
common stock to Allegheny in exchange for its interest in a jointly owned
network located in State College, Pennsylvania. These shares were sold in
reliance on the exemption under section 4(2) of the Securities Act.

   On March 19, 2001, Adelphia Business Solutions issued and sold 25,322 shares
of Class A common stock to the public in a rights offering at a price of $7.28
per share. Simultaneously, in a private placement in reliance on the exemption
under section 4(2) of the Securities Act, Adelphia purchased 11,820,070 and
51,459,624 shares of Class A and Class B Common Stock, respectively, in the
rights offering at a price of $7.28 per share. The net proceeds of
approximately $460.9 million will be used to pay down the Company's outstanding
borrowings under its revolving bank credit facility, all of which, subject to
the terms and maturity of that credit facility, may be re-borrowed and used by
the Company for general corporate purposes.

                       Adelphia Business Solutions, Inc.
            Charter of the Audit Committee of the Board of Directors

I. Audit Committee Purpose

   The Audit Committee is appointed by the Board of Directors of Adelphia
Business Solutions, Inc. (the "Company") to assist the Board in fulfilling its
oversight responsibilities. The Audit Committee's primary duties and
responsibilities are to:

  .   Monitor the integrity of the Company's financial reporting process and
      systems of internal controls regarding finance, accounting, and legal
      compliance.

  .   Monitor the independence and performance of the Company's independent
      auditors and internal auditing department.

  .   Provide an avenue of communication among the independent auditors,
      management, the internal auditing department, and the Board of
      Directors.

   The Audit Committee has the authority to conduct any investigation
appropriate to fulfilling its responsibilities, and it has direct access to the
independent auditors as well as anyone in the organization. The Audit Committee
has the ability to retain, at the Company's expense, special legal, accounting,
or other consultants or experts it deems necessary in the performance of its
duties.

II. Audit Committee Composition and Meetings

   Audit Committee members shall meet the applicable independence and
experience requirements, in effect from time to time, of the National
Association of Securities Dealers, Inc. ("NASD") or such other applicable stock
exchange or association on which the Company's common stock is then listed. The
Audit Committee shall be comprised of three or more directors as determined by
the Board. All members of the Committee shall have a basic understanding of
finance and accounting and be able to read and understand fundamental financial
statements, and at least one member of the Committee shall have accounting or
related financial management expertise.

   Audit Committee members shall be appointed by the Board on recommendation of
the Nominating Committee. If an Audit Committee Chair is not designated or
present, the members of the Committee may designate a Chair by majority vote of
the Committee membership.

   The Committee shall meet at least four times annually, or more frequently as
circumstances dictate. The Audit Committee Chair shall prepare and/or approve
an agenda in advance of each meeting. Audit Committee members may attend
meetings in person, by telephone conference or similar communications
equipment, or as otherwise permitted by law. The Committee should meet

committee to discuss any matters that the Committee or each of these groups
believe should be discussed.

III. Audit Committee Responsibilities and Duties

   the Charter to the Board of Directors for approval and have the document

2. Review the Company's annual audited financial statements prior to filing or
   distribution. Review should include discussion with management and

                                      B-1


3. In consultation with management, the independent auditors, and the internal
   auditors, consider the integrity of the Company's financial reporting
   processes and controls. Discuss any significant financial risk exposures and

   exposures. Review significant findings prepared by the independent auditors
   and the internal auditing department together with management's responses.

4. Review with financial management and the independent auditors the Company's
   quarterly financial results prior to the release of earnings and the
   Company's quarterly financial statements prior to filing or distribution.
   Discuss any significant changes to the Company's accounting principles and

   accordance with Statement on Auditing Standards No. 61 ("SAS 61") (see item
   9). The Chair of the Committee may represent the entire Audit Committee for
   purposes of this review.

 Independent Auditors

5. The independent auditors are ultimately accountable to the Audit Committee
   and the Board of Directors. The Audit Committee shall review the
   independence and performance of the auditors and annually recommend to the
   Board of Directors the appointment of the independent auditors or approve
   any discharge of auditors when circumstances warrant.

6. Approve the fees and other significant compensation to be paid to the
   independent auditors.

7. On an annual basis, the Committee should review and discuss with the
   independent auditors all significant relationships they have with the
   Company that could impair the auditors' independence.

8. Review the independent auditors audit plan--discuss scope, staffing,
   reliance upon management, and internal audit and general audit approach.

                                      B-2


 Scope of Duties

18. While the Audit Committee has the responsibilities and powers set forth in
    this Charter, it is not the duty of the Audit Committee to plan, direct or
    conduct audits, or to determine whether the Company's financial statements
    are complete and accurate and are in accordance with generally accepted
    accounting principles. These are the responsibilities of management and/or
    the independent auditors. Nor is it the duty of the Audit Committee to
    conduct investigations, to resolve disagreements, if any, between
    management and the independent auditors or to assure compliance with laws
    and regulations and any internal rules or codes of conduct of the Company.
